Diligentiae tuae, qua in iuvenili aetate non vanitati sed sapientiae intendis, studio provocatus, et desiderio satisfacere cupiens, libro Aristotelis qui Perihermeneias dicitur, multis obscuritatibus involuto, inter multiplices occupationum mearum sollicitudines, expositionem adhibere curavi, hoc gerens in animo sic altiora pro posse perfectioribus exhibere ut tamen iunioribus proficiendi auxilia tradere non recusem. Suscipiat igitur studiositas tua praesentis expositionis munus exiguum, ex quo, si profeceris, provocare me poteris ad maiora.
My attention has been drawn to your diligence, whereby in your youthful state you pursue not vanity but the study of wisdom. Desiring to satisfy your desire, I have taken the trouble, in the midst of many demanding tasks, to undertake an exposition on the book of Aristotle called Peri hermeneias, which contains many obscure passages. I aimed, as far as possible, to explain higher things to advanced students, without depriving the younger ones of the assistance they need to make progress. Therefore, may your studious self accept the small gift of the present exposition. If it helps you to make progress, you may stimulate me to do you greater favors.

Prooemium
Introduction
16a1. Primum oportet constituere quid sit nomen et quid sit verbum. Postea quid negatio et quid affirmatio, et enunciatio et oratio.
16a1. First, we must determine what a name is and what a verb is; then what negation is and affirmation, and the enunciation and speech.
Peri.L1
1. Sicut Philosophus dicit in III De anima, duplex est operatio intellectus:
There is a twofold operation of the intellect, as the Philosopher says in On the Soul 3.6, 430a26.
Peri.L1
una quidem quae dicitur indivisibilium intelligentia, per quam scilicet intellectus apprehendit essentiam uniuscuiusque rei in se ipsa;
One is the understanding of simple objects, that is, the operation by which the intellect apprehends just the essence of a thing alone.
Peri.L1
alia est autem operatio intellectus componentis et dividentis;
The other is the operation of composing and dividing.
Peri.L1
additur autem et tertia operatio ratiocinandi, secundum quod ratio procedit a notis ad inquisitionem ignotorum.
There is also a third operation, that of reasoning, by which reason proceeds from what is known to the investigation of things that are unknown.
Peri.L1
Harum autem operationum prima ordinatur ad secundam, quia non potest esse compositio et divisio nisi simplicium apprehensorum; secunda vero ordinatur ad tertiam, quia videlicet oportet quod ex aliquo vero cognito cui intellectus assentiat procedatur ad certitudinem accipiendam de aliquibus ignotis.
The first of these operations is ordered to the second, for there cannot be composition and division unless things have already been apprehended simply. The second, in turn, is ordered to the third, for clearly we must proceed from some known truth to which the intellect assents in order to have certitude about something not yet known.
Peri.L1
2. Cum autem logica dicatur rationalis scientia, necesse est quod eius consideratio versetur circa ea quae pertinent ad tres praedictas operationes rationis; de his igitur quae pertinent ad primam operationem intellectus, id est de his quae simplici intellectu concipiuntur, determinat Aristoteles in libro Praedicamentorum; de his vero quae pertinent ad secundam operationem, scilicet de enunciatione affirmativa et negativa, determinat Philosophus in libro Perihermeneias; de his vero quae pertinent ad tertiam operationem determinat Aristoteles in libro Priorum et in consequentibus, in quibus agitur de syllogismo simpliciter et de diversis syllogismorum et argumentationum speciebus, quibus ratio de uno procedit ad aliud; et ideo secundum praedictum ordinem trium operationum, liber Praedicamentorum ad librum Perihermeneias ordinatur, qui ordinatur ad librum Priorum et consequentes.
Since logic is called rational science, it must direct its consideration to the things that belong to the three operations of reason we have mentioned. Accordingly, Aristotle treats those belonging to the first operation of the intellect, that is, those conceived by simple understanding, in the book Categories; those belonging to the second operation, that is, affirmative and negative enunciation, in the book On Interpretation; and those belonging to the third operation in the book Prior Analytics and the books following it, in which he treats the syllogism absolutely, the different kinds of syllogism, and the species of argumentation by which reason proceeds from one thing to another. And since the three operations of reason are ordered to each other, so are the books: the Categories is ordered to On Interpretation, and On Interpretation to the Prior Analytics and the books following it.
Peri.L1
3. Dicitur ergo liber iste, qui prae manibus habetur, Perihermeneias, quasi De interpretatione. Dicitur autem interpretatio, secundum Boethium, vox significativa quae per se aliquid significat, sive sit complexa sive incomplexa; unde coniunctiones et praepositiones et alia huiusmodi non dicuntur interpretationes, quia non per se aliquid significant; similiter etiam voces significantes naturaliter, non ex proposito aut cum imaginatione aliquid significandi, sicut sunt voces brutorum animalium, interpretationes dici non possunt: qui enim interpretatur, aliquid exponere intendit; et ideo sola nomina et verba et orationes dicuntur interpretationes, de quibus in hoc libro determinat. Sed tamen nomen et verbum magis interpretationis principia esse videntur quam interpretationes: ille enim interpretari videtur qui exponit aliquid esse verum vel falsum; et ideo sola oratio enuntiativa, in qua verum vel falsum invenitur, interpretatio vocatur; ceterae vero orationes, ut optativa et imperativa, magis ordinantur ad exprimendum affectum quam ad interpretandum id quod in intellectu habetur. Intitulatur ergo liber iste De interpretatione, ac si dicetur De enuntiativa oratione, in qua verum vel falsum invenitur; non autem hic agitur de nomine et verbo nisi in quantum sunt partes enuntiationis: est enim proprium uniuscuiusque scientiae partes subiecti tradere, sicut et passiones.
The one we are now examining is named Peri hermeneias, that is, On Interpretation. Interpretation, according to Boethius, is significant vocal sound—whether complex or incomplex—which signifies something by itself. Conjunctions, then, and prepositions and other words of this kind are not called interpretations since they do not signify anything by themselves. Nor can sounds signifying naturally but not from purpose or in connection with a mental image of signifying something—such as the sounds of brute animals—be called interpretations, for one who interprets intends to explain something. Therefore only names and verbs and speech are called interpretations and these Aristotle treats in this book. The name and verb, however, seem to be principles of interpretation rather than interpretations, for one who interprets seems to explain something as either true or false. Therefore, only enunciative speech in which truth or falsity is found is called interpretation. Other kinds of speech, such as optatives and imperatives, are ordered rather to expressing volition than to interpreting what is in the intellect. This book, then, is entitled On Interpretation, that is to say, On Enunciative Speech, in which truth or falsity is found. The name and verb are treated only insofar as they are parts of the enunciation; for it is proper to a science to treat the parts of its subject as well as its properties.
Peri.L1
Patet igitur ad quam partem philosophiae pertineat liber iste et quae sit necessitas istius et quem ordinem teneat inter logicae libros.
It is clear, then, to which part of philosophy this book belongs, what its necessity is, and what its place is among the books on logic.
Peri.L1
4. Praemittit autem Philosophus huic operi prooemium, in quo sigillatim exponit ea quae in hoc libro sunt tractanda.
The Philosopher begins this work with an introduction, in which he points out one by one the things that are to be treated.
Peri.L1
Et, quia omnis scientia praemittit ea quae de principiis sunt, partes autem compositorum sunt eorum principia, ideo oportet intendenti tractare de enuntiatione praemittere de partibus eius; unde dicit: Primum oportet constituere, id est definire, quid sit nomen et quid sit verbum. In Graeco habetur: Primum oportet poni, et idem significatur: quia enim demonstrationes definitiones praesupponunt ex quibus concludunt, merito dicuntur positiones; et ideo hic praemittuntur solae definitiones eorum de quibus agendum est, quia ex definitionibus alia cognoscuntur.
For, since every science begins with a treatment of the principles, and the principles of composite things are their parts, one who intends to treat enunciation must begin with its parts. Thus, Aristotle begins by saying: first we must determine, that is, define, what a noun is and what a verb is (16a1). In the Greek text it is: first we must posit, which signifies the same thing, for demonstrations presuppose definitions, from which they conclude, and hence definitions are rightly called “positions.” This is the reason he only points out here the definitions of the things to be treated; for from definitions other things are known.
Peri.L1
5. Si quis autem quaerat, cum in libro Praedicamentorum de simplicibus dictum sit, quae fuit necessitas ut hic rursum de nomine et verbo determinaretur,
It might be asked why it is necessary to treat simple things again, that is, the name and the verb, for they were treated in the book Categories.
Peri.L1
ad hoc dicendum quod simplicium dictionum triplex potest esse consideratio:
In answer to this, we should say that simple words can be considered in three ways:
Peri.L1
una quidem secundum quod absolute significant simplices intellectus, et sic earum consideratio pertinet ad librum Praedicamentorum;
first, as they signify simple intellection absolutely, which is the consideration proper to the book Categories;
Peri.L1
alio modo secundum rationem prout sunt partes enuntiationis, et sic determinatur de eis in hoc libro (et ideo traduntur sub ratione nominis et verbi, de quorum ratione est quod significent aliquid cum tempore vel sine tempore et alia huiusmodi quae pertinent ad rationem dictionum secundum quod constituunt enuntiationem);
second, according to their function as parts of the enunciation, which is the way they are considered in this book. Hence, they are treated here under the formality of the name and the verb, and under this formality they signify something with time or without time and other things of the kind that belong to the formality of words as they are components of an enunciation.
Peri.L1
tertio modo considerantur secundum quod ex eis constituitur syllogisticus ordo, et sic determinatur de eis sub ratione terminorum in libro Priorum.
Finally, simple words may be considered as they are components of a syllogistic ordering. They are treated then under the formality of terms, and Aristotle does this in the book Prior Analytics.
Peri.L1
6. Potest iterum dubitari quare, praetermissis aliis orationum partibus, de solo nomine et verbo determinet? Ad quod dicendum quod, quia de simplici enuntiatione determinare intendit, sufficit ut solas illas partes orationis pertractet ex quibus ex necessitate simplex oratio constat; potest autem ex solo nomine et verbo simplex enuntiatio fieri, non autem ex aliis orationis partibus sine his; et ideo sufficiens ei fuit de his duabus determinare.
It might be asked why he treats only the name and verb and omits the other parts of speech. The reason could be that Aristotle intends to establish rules about the simple enunciation and for this it is sufficient to consider only the parts of the enunciation that are necessary for simple speech. A simple enunciation can be formed from just a name and a verb, but it cannot be formed from other parts of speech without these. Therefore, it is sufficient to treat these two.
Peri.L1
Vel potest dici quod sola nomina et verba sunt principales orationis partes: sub nominibus enim comprehenduntur pronomina quae, etsi <non> naturam, personam tamen determinant, sub verbo vero participium, quod significat tempus, quamvis et cum nomine convenientiam habeat. Alia vero sunt magis colligationes partium orationis, significantes habitudinem unius ad aliam, quam orationis partes, sicut clavi et alia huiusmodi non sunt partes navis, sed partium navis coniunctiones.
On the other hand, the reason could be that names and verbs are the principal parts of speech. Pronouns, which do not name a nature but determine a person—and therefore are put in place of names—are comprehended under names. The participle—although it has similarities with the name—signifies with time and is therefore comprehended under the verb. The others are things that unite the parts of speech. They signify relations of one part to another rather than parts of speech, as nails and other parts of this kind are not parts of a ship, but connect the parts of a ship.
Peri.L1
7. His igitur praemissis quasi principiis, subiungit de hiis quae pertinent ad principalem intentionem, dicens: Postea quid negatio et quid affirmatio, quae sunt enuntiationis partes non quidem integrales sicut nomen et verbum (alioquin oporteret omnem enuntiationem ex affirmatione et negatione compositam esse), sed partes subiectivae, id est species. Quod quidem nunc supponatur, posterius autem manifestabitur.
After he has proposed these parts [the name and the verb] as principles, Aristotle states what he principally intends to establish: then what negation is and affirmation (16a1). These, too, are parts of the enunciation; however, they are not integral parts, as are the name and the verb (otherwise every enunciation would have to be formed from an affirmation and negation), but subjective parts, that is, species. This is supposed here but will be proved later.
Peri.L1
8. Sed potest dubitari, cum enuntiatio dividatur in categoricam et hypotheticam, quare de his non facit mentionem sicut de affirmatione et negatione? Et potest dici quod hypothetica enuntiatio ex pluribus categoricis componitur, unde non differunt nisi secundum differentiam unius et multi.
Since enunciation is divided into categorical and hypothetical, it might be asked why he does not list these as well as affirmation and negation. In reply to this we could say that Aristotle has not added these because the hypothetical enunciation is composed of many categorical propositions, and thus categorical and hypothetical only differ according to the difference of one and many.
Peri.L1
Vel potest dici, et melius, quod hypothetica enuntiatio non continet absolutam veritatem, cuius cognitio requiritur in demonstratione, ad quam principaliter ille liber ordinatur, sed significat aliquid verum esse ex suppositione, quod non sufficit in scientiis demonstrativis, nisi confirmetur per absolutam veritatem simplicis enuntiationis; et ideo Aristoteles praetermisit tractatum de hypotheticis enuntiationibus et syllogismis.
Or we could say, and this would be a better reason, that the hypothetical enunciation does not contain absolute truth, the knowledge of which is required in demonstration and to which this book is principally ordered. Rather, it signifies something as true by supposition, which does not suffice for demonstrative sciences unless it is confirmed by the absolute truth of the simple enunciation. This is the reason Aristotle does not treat either hypothetical enunciations or syllogisms.
Peri.L1
Subdit autem: et enunciatio, quae est genus negationis et affirmationis, et oratio, quae est genus enuntiationis.
He adds: and the enunciation (16a1), which is the genus of negation and affirmation, and speech, which is the genus of enunciation.
Peri.L1
9. Si quis ulterius quaerat quare non facit ulterius mentionem de voce, dicendum est quod vox est quiddam naturale, unde pertinet ad considerationem naturalis philosophiae, ut patet in II De anima et ultimo De generatione animalium; unde non est proprie orationis genus, sed assumitur ad constitutionem orationis sicut res naturales ad constitutionem artificialium.
If it should be asked why, besides these, he does not mention vocal sound, it is because vocal sound is something natural and therefore belongs to the consideration of natural philosophy, as is evident in On the Soul 2.8, 420b5–421a6, and at the end of On the Generation of Animals.1 Also, since it is something natural, vocal sound is not properly the genus of speech, but is presupposed for the forming of speech, as natural things are presupposed for the formation of artificial things.
Peri.L1
10. Videtur autem ordo enuntiationis esse praeposterus: nam affirmatio naturaliter prior est negatione, et his enuntiatio prior est sicut genus, et per consequens oratio enuntiatione. Sed dicendum est quod, quia a partibus inceperat enumerare, procedit a partibus ad totum; negationem autem, quae divisionem continet, eadem ratione praeponit affirmationi, quae ratio consistit in compositione, quia divisio magis accedit ad partes, compositio vero magis accedit ad totum.
In this introduction, however, Aristotle seems to have inverted the order of the enunciation, for affirmation is naturally prior to negation, and enunciation is prior to these as a genus; consequently, speech is prior to enunciation. We could reply to this that he began to enumerate from the parts; consequently, he proceeds from the parts to the whole. He puts negation, which contains division, before affirmation, which consists of composition, for the same reason: division is closer to the parts, composition closer to the whole.
Peri.L1
Vel potest dici, secundum quosdam, quod praemittitur negatio quia in his quae possunt esse et non esse, prius est non esse, quod significat negatio, quam esse, quod significat affirmatio.
Or we could say, as some do, that he puts negation first because in those things that can be and not be, non-being, which negation signifies, is prior to being, which affirmation signifies.
Peri.L1
Si tamen sunt species ex aequo dividentes genus, sunt simul natura; unde non refert quod eorum praeponatur.
Aristotle, however, does not refer to the fact that one of them is placed before the other, for they are species equally dividing a genus and are therefore simultaneous according to nature.
Peri.L1
L. 2 (A.1, 16a3–16a9)The signification of vocal soundDe vocum significatione
16a3. Sunt ergo ea quae sunt in voce earum quae sunt in anima passionum notae.
16a3. Now, those that are in vocal sound are signs of passions in the soul.
Peri.L2
Et ea quae scribuntur eorum quae sunt in voce.
And those that are written are signs of those in vocal sound.
Peri.L2
16a5. Et quemadmodum nec litterae omnibus eaedem, sic nec eaedem voces.
16a5. And just as letters are not the same for all men, so neither are vocal sounds the same.
Peri.L2
Quorum autem hae primorum notae sunt, eaedem omnibus passiones animae sunt, et quorum hae similitudines, res etiam eaedem.
But the passions of the soul, of which vocal sounds are the first signs, are the same for all; and the things of which passions of the soul are likenesses are also the same.
Peri.L2
De his quidem dictum est in his quae de anima dicta sunt; alterius est enim negotii.
This has been discussed, however, in our study of the soul for it belongs to another subject of inquiry.
Peri.L2
11. Sunt ergo ea quae sunt in voce et cetera. Praemisso prooemio, Philosophus accedit ad propositum exequendum.
Now, those that are in vocal sound. After his introduction the Philosopher begins to investigate the things he has proposed.
Peri.L2
Et, quia ea de quibus promiserat se dicturum sunt voces significativae, complexae vel incomplexae, ideo praemittit tractatum de significatione vocum;
Since the things he promised to speak of are either complex or incomplex significant vocal sounds, he prefaces this with a treatment of the signification of vocal sounds;
Peri.L2
et deinde de vocibus significativis determinat, de quibus in prooemio se dicturum praedixerat, et hoc ibi: Nomen <ergo> est vox significativa et cetera.
then he takes up the significant vocal sounds he proposed in the introduction, at: a name, then, is a vocal sound significant by convention (16a19).
Peri.L2
Circa primum duo facit:
About the first he does two things:
Peri.L2
primo determinat qualis sit significatio vocum;
first, he determines what kind of signification vocal sound has;
Peri.L2
secundo ostendit differentiam significationum vocum complexarum et incomplexarum, ibi: Est autem quemadmodum in amina et cetera.
second, he shows the difference between the signification of complex and incomplex vocal sounds where he says: as sometimes there is thought in the soul (16a9; [23]).
Peri.L2
Circa primum duo facit:
About the first he does two things:
Peri.L2
primo quidem praemittit ordinem significationis vocum;
first, he presents the order of the signification of vocal sounds;
Peri.L2
secundo ostendit qualis sit vocum significatio, utrum sit ex natura vel ex positione, ibi: Et quemadmodum nec litterae omnibus eaedem etc.
second, he shows what kind of signification vocal sound has—that is, whether it is from nature or by imposition. This he does where he says: and just as letters are not the same for all men.(16a5; [18]).
Peri.L2
12. Est ergo considerandum quod circa primum tria proponit, ex quorum uno intelligitur quartum: proponit enim scripturam, voces et animae passiones, ex quibus intelliguntur res: nam passio est ex impressione alicuius agentis, et sic passiones animae originem habent ab ipsis rebus. Et, si quidem homo esset naturaliter animal solitarium, sufficerent sibi animae passiones, quibus ipsis rebus conformaretur, ut earum notitiam in se haberet; sed, quia homo est naturaliter animal politicum et sociale, necesse fuit quod conceptiones unius hominis innotescerent alii, quod fit per vocem; et ideo necesse fuit esse voces significativas ad hoc quod homines ad invicem conviverent; unde illi qui sunt diversarum linguarum non possunt bene ad invicem convivere. Rursus, si homo uteretur sola cognitione sensitiva, quae respicit ad hic et nunc, sufficeret sibi ad convivendum aliis vox significativa, sicut et ceteris animalibus, quae per quasdam voces suas conceptiones invicem sibi manifestant; sed, quia homo etiam utitur intellectuali cognitione, quae abstrahit ab hic et nunc, consequitur ipsum sollicitudo non solum de praesentibus secundum locum et tempus, sed etiam de his quae distant loco et futura sunt tempore; unde, ut homo conceptiones suas etiam his qui distant secundum locum et his qui venturi sunt in futuro tempore manifestet, necessarius fuit usus scripturae.
He proposes three things about the order of signification of vocal sounds, from one of which is understood a fourth. He proposes writing, vocal sounds, and the soul’s passions. “Things” is understood from the last, for a passion is from the impression of something acting, and hence the soul’s passions have their origin from things. Now, if man were by nature a solitary animal, the passions of the soul by which he was conformed to things to have knowledge of them would be sufficient for him; but since he is by nature a political and social animal, his conceptions had to be made known to others. He does this through vocal sound. Therefore, there had to be significant vocal sounds so that men might live together, and thus those who speak different languages find it difficult to live together in social unity. Again, if man had only sensitive cognition, which is of the here and now, such significant vocal sounds as the other animals use to manifest their conceptions to each other would be sufficient for him to live with others. But man also has intellectual cognition, which abstracts from the here and now; consequently, he is concerned with things distant in place and future in time as well as things present according to time and place. Thus, the use of writing was necessary so that he might manifest his conceptions to those who are distant according to place and to those who will come in future time.
Peri.L2
13. Sed, quia logica ordinatur ad cognitionem de rebus sumendam, significatio vocum, quae est immediata ipsis conceptionibus intellectus, pertinet ad principalem considerationem ipsius, significatio autem litterarum, tanquam magis remota, non pertinet ad eius considerationem, sed magis ad considerationem grammatici; et ideo, exponens ordinem significationum, non incipit a litteris, sed a vocibus.
However, since logic is ordered to obtaining knowledge about things, the signification of vocal sounds, which is immediate to the conceptions of the intellect, is its principal consideration. The signification of written signs, being more remote, belongs to the consideration of the grammarian rather than the logician. Aristotle therefore begins his explanation of the order of signification from vocal sounds, not written signs.
Peri.L2
Quarum primo significationem exponens, dicit: Sunt ergo ea quae sunt in voce notae, id est signa, earum passionum quae sunt in anima.
First, he explains the signification of vocal sounds: now, those that are in vocal sound are signs of passions in the soul (16a3).
Peri.L2
Dicit autem ergo, quasi ex praemissis concludens: ut supra dixerat determinandum esse de nomine et verbo et aliis praedictis, haec autem sunt voces significativae, ergo oportet significationem vocum exponere.
He says therefore as if concluding from premises because he has already said that we must establish what a name, verb, and the other things he mentioned are, but since these are significant vocal sounds, therefore signification of vocal sounds must be explained.
Peri.L2
14. Utitur autem hoc modo loquendi ut dicat: ea quae sunt in voce, et non: voces, ut quasi continuatim cum praedictis loquatur: dixerat enim dicendum esse de nomine et verbo et aliis huiusmodi;
When he says: those that are in vocal sound, and not vocal sounds, his mode of speaking implies a continuity with what he has just been saying, namely, that we must define the name and the verb and other things of this kind.
Peri.L2
haec autem tripliciter habent esse:
Now, these have being in three ways:
Peri.L2
uno quidem modo in conceptione intellectus;
in the conception of the intellect,
Peri.L2
alio modo in prolatione vocis;
in the utterance of the voice,
Peri.L2
tertio modo in descriptione litterarum;
and in the writing of letters.
Peri.L2
dicit ergo: ea quae sunt in voce, ac si dicat: nomina et verba et alia consequentia, quae tantum sunt in voce, sunt notae etc.
Therefore, when he says: those that are in vocal sound, he could mean names and verbs and the other things we are going to define, which, insofar as they are in vocal sound, are signs.
Peri.L2
Vel, quia non omnes voces sunt significativae, et earum quaedam sunt significativae naturaliter, quae longe sunt a ratione nominis et verbi et aliorum consequentium, ut appropriet suum dictum ad ea de quibus intendit, ideo dicit: quae sunt in voce, id est quae continentur sub voce sicut partes sub toto.
Or, he may be speaking in this way because not all vocal sounds are significant, and of those that are, some are significant naturally, and are thus different in nature from the name and the verb and the other things to be defined. Therefore, to adapt what he has said to the things of which he intends to speak, he says: those that are in vocal sound, that is, that are contained under vocal sound as parts under a whole.
Peri.L2
Vel, quia vox est quiddam naturale, nomen autem et verbum significant ex institutione humana, quae advenit naturali rei sicut materiae, ut forma lecti ligno, ideo ad significandum nomina et verba et alia consequentia, dicit: ea quae sunt in voce, ac si de lecto diceretur: ea quae sunt in ligno.
Or, it could because vocal sound is something natural, whereas the name and the verb signify by human institution—that is, the signification is added to the natural thing as a form to matter, as the form of a bed is added to wood. Therefore, to designate names and verbs and the other things he is going to define, he says: those that are in vocal sound, in the same way that he would say of a bed: that which is in wood.
Peri.L2
15. Circa id autem quod dicit: earum quae sunt in anima passionum, considerandum est quod passiones animae communiter dici solent appetitus sensibilis affectiones, sicut ira, gaudium et alia huiusmodi, ut dicitur in II Ethicorum; et verum est quod huiusmodi passiones significant naturaliter quaedam voces hominum, ut gemitus infirmorum et alia similia, ut dicitur in I Politicae. Sed nunc est sermo de vocibus significativis ex institutione humana, et ideo oportet passiones animae hic intelligere intellectus conceptiones quas nomina et verba et orationes significant, secundum sententiam Aristotelis: non enim potest esse quod significent immediate ipsas res, ut ex modo significandi apparet: significat enim hoc nomen ‘homo’ naturam humanam in abstractione a singularibus, unde non potest esse quod significet immediate hominem singularem. Unde Platonici posuerunt quod significaret ipsam ideam hominis separatam; sed, quia haec secundum suam abstractionem non subsistit realiter secundum sententiam Aristotelis, sed est in solo intellectu, ideo necesse fuit Aristoteli dicere quod voces significant intellectus conceptiones immediate, et eis mediantibus res.
When he speaks of passions in the soul, we are apt to think of the emotions of the sensitive appetite, such as anger, joy, and the other passions that are customarily and commonly called passions of the soul, as is the case in Ethics 2.5, 1105b21. It is true that some of the vocal sounds man makes naturally signify passions of this kind, such as the groans of the sick and the sounds of other animals, as is said in Politics 1.2, 1253a10–14. But here Aristotle is speaking of vocal sounds that are significant by human institution. Therefore, “passions in the soul” must be understood here as conceptions of the intellect; names, verbs, and speech signify these conceptions of the intellect immediately, according to the teaching of Aristotle. They cannot immediately signify things, as is clear from the mode of signifying. For the name “man” signifies human nature in abstraction from singulars; hence it is impossible that it immediately signify a singular man. For this reason, the Platonists held that it signified the separated idea of man. But because in Aristotle’s teaching man in the abstract does not really subsist, but is only in the mind, it was necessary for Aristotle to say that vocal sounds signify the conceptions of the intellect immediately and things by means of them.
Peri.L2
16. Sed, quia non est consuetum quod intellectus conceptiones Aristoteles nominet passiones, ideo Andronicus posuit hunc librum non esse Aristotelis. Sed manifeste invenitur in I De anima quod passiones animae vocat omnes animae operationes, unde et ipsa conceptio intellectus passio potest dici, vel quia intelligere non est sine phantasmate, quod non est sine corporali passione (unde et imaginationem Philosophus in III De anima nominat passivum intellectum), vel quia, extenso nomine passionis ad omnem receptionem, ipsum intelligere intellectus possibilis quoddam pati est, ut dicitur in III De anima.
Since Aristotle did not customarily speak of conceptions of the intellect as passions, Andronicus took the position that this book was not Aristotle’s. In On the Soul I, however, it is obvious that he calls all of the operations of the soul “passions of the soul.” Thus, even the conception of the intellect can be called a passion, and this is either because we do not understand without a phantasm, which requires corporeal passion (for which reason the Philosopher calls the imaginative power the passive intellect),1 or because by extending the name of passion to every reception, the understanding of the possible intellect is also a kind of undergoing. 2
Peri.L2
Utitur autem potius nomine passionum quam intellectuum,
Now, Aristotle uses the name passion rather than understanding for two reasons:
Peri.L2
tum quia ex aliqua animae passione provenit, puta ex amore vel odio, ut homo interiorem conceptum per vocem alteri significare velit,
first, because man wills to signify an interior conception to another through vocal sound as a result of some passion of the soul, such as love or hate;
Peri.L2
tum etiam quia significatio vocum refertur ad conceptionem intellectus secundum quod oritur a rebus per modum cuiusdam impressionis vel passionis.
second, because the signification of vocal sound is referred to the conception of the intellect inasmuch as the conception arises from things by way of a kind of impression or passion.
Peri.L2
17. Secundo, cum dicit: Et ea quae scribuntur et cetera, agit de significatione scripturae.
When he says: and those that are written are signs of those in vocal sound (16a3), he treats of the signification of writing.
Peri.L2
Et, secundum Alexandrum, hoc inducitur ad manifestandum praecedentem sententiam per modum similitudinis, ut sit sensus: Ita ea quae sunt in voce sunt signa passionum animae sicut et litterae sunt signa vocum; quod etiam manifestat per sequentia, cum dicit: Et quemadmodum nec litterae et cetera, inducens hoc quasi signum praecedentis: quod enim litterae significent voces, significatur per hoc quod, sicut sunt diversae voces apud diversos, ita et diversae litterae; et, secundum hanc expositionem, ideo non dixit: et litterae eorum quae sunt in voce, sed ea quae scribuntur et cetera, quia etiam litterae dicuntur in prolatione et in scriptura, quamvis magis proprie secundum quod sunt in scriptura dicantur litterae, secundum autem quod sunt in prolatione dicantur elementa vocum.
According to Alexander, he introduces this to make the preceding clause evident by means of a similitude. The meaning is as follows. Those that are in vocal sound are signs of the passions of the soul in the way in which letters are of vocal sound. He manifests this point where he says: and just as letters are not the same for all men, so neither are vocal sounds the same (16a5), introducing this as a sign of the preceding. For when he says that there are different letters among different people just as there are diverse vocal sounds, he means that letters signify vocal sounds. And according to this exposition, Aristotle said: those that are written are signs, rather than: letters are signs of those that are in vocal sound, because they are called letters in both speech and writing (though they are more properly called letters in writing, and elements of vocal sound in speech).
Peri.L2
Sed, quia Aristoteles non dicit: Sicut et ea quae scribuntur, sed continuam narrationem facit, melius est ut dicatur, sicut Porphyrius exposuit, quod Aristoteles procedit ulterius ad complendum ordinem significationis: postquam enim dixerat quod nomina et verba quae sunt in voce sunt signa eorum quae sunt in anima, continuatim subdit quod nomina et verba quae scribuntur sunt signa eorum nominum et verborum quae sunt in voce.
Aristotle, however, does not say: just as those that are written, but continues with his account. Therefore, it is better to say (as Porphyry does) that Aristotle adds this to complete the order of signification; for after he says that names and verbs in vocal sound are signs of those in the soul, he adds—in continuity with this—that names and verbs that are written are signs of the names and verbs that are in vocal sound.
Peri.L2
18. Deinde cum dicit: Et quemadmodum et cetera, ostendit differentiam praemissorum significantium et significatorum, quantum ad hoc quod est esse secundum naturam vel non esse.
Then, where he says: and just as letters (16a5), he shows that the foresaid things differ as signified and signifying, inasmuch as they are either according to nature or not.
Peri.L2
Et circa hoc tria facit.
He makes three points here.
Peri.L2
Primo enim ponit quoddam signum quo manifestatur quod nec voces nec litterae naturaliter significant: ea enim quae naturaliter sunt, sunt eadem apud omnes; significatio autem litterarum et vocum, de quibus nunc agimus, non est eadem apud omnes. Et hoc quidem apud nullos unquam dubitatum fuit quantum ad litteras, quarum non solum ratio significandi est ex positione, sed etiam ipsarum formatio fit per artem; voces autem naturaliter formantur, unde et apud quosdam dubitatum fuit utrum naturaliter significent. Sed Aristoteles hoc determinat ex similitudine litterarum, quae sicut non sunt eaedem apud omnes, ita nec voces, unde manifeste relinquitur quod, sicut nec litterae, ita nec voces naturaliter significant, sed ex institutione humana. Voces autem illae quae naturaliter significant, sicut gemitus infirmorum et alia huiusmodi, sunt eadem apud nos.
First, he posits a sign to show that neither vocal sounds nor letters signify naturally. Things that signify naturally are the same among all men, but the signification of letters and vocal sounds, which is the point at issue here, is not the same among all men. There has never been any question about this in regard to letters, for their character of signifying is from imposition and their very formation is through art. Vocal sounds, however, are formed naturally, and hence there is a question as to whether they signify naturally. Aristotle determines this by comparison with letters: these are not the same among all men, and so neither are vocal sounds the same. Consequently, like letters, vocal sounds do not signify naturally but by human institution. The vocal sounds that do signify naturally, such as groans of the sick and others of this kind, are the same among all men.
Peri.L2
19. Secundo, ibi: Quorum autem hae priorum et cetera, ostendit passiones animae naturaliter esse sicut et res, per hoc quod eaedem sunt apud omnes. Unde dicit: autem, id est sed, passiones animae sunt eaedem omnibus; quorum primorum, id est quarum passionum primarum, hae, scilicet voces, sunt notae, id est signa (comparantur enim passiones animae ad voces sicut primum ad secundum: voces enim non proferuntur nisi ad exprimendum interiores animae passiones), et res etiam eaedem, scilicet sunt apud omnes, quorum, id est quarum rerum, hae, scilicet passiones animae, sunt similitudines.
Second, when he says: but the passions of the soul (16a5), he shows that passions of the soul exist naturally, just as things exist naturally, for they are the same among all men. Thus he says: but the passions of the soul are the same for all; of which the first, that is, of which passions, which are first, these, namely, vocal sounds, are tokens, that is, signs (for passions of the soul are compared to vocal sounds as first to second, since vocal sounds are produced only to express interior passions of the soul). and so also the things are the same, that is, are the same among all, of which, that is, of which things, these passions of the soul are likenesses.
Peri.L2
Ubi attendendum est quod litteras dixit esse notas, id est signa, vocum, et voces passionum animae similiter; passiones autem animae dicit esse similitudines rerum. Et hoc ideo, quia res non cognoscitur ab anima nisi per aliquam sui similitudinem existentem vel in sensu vel in intellectu; litterae autem ita sunt signa vocum et voces passionum quod non attenditur ibi aliqua ratio similitudinis, sed sola ratio institutionis, sicut et in multis aliis signis, ut tuba est signum belli; in passionibus autem animae oportet attendi rationem similitudinis ad exprimendas res, quia eas naturaliter designant, non ex institutione.
Notice he says here that letters are signs—that is, signs of vocal sounds—and similarly that vocal sounds are signs of passions of the soul, but that passions of the soul are likenesses of things. This is because a thing is not known by the soul unless there is some likeness of the thing existing either in the sense or in the intellect. Now, letters are signs of vocal sounds and vocal sounds of passions in such a way that we do not attend to any idea of likeness in regard to them but only one of institution, as is the case in regard to many other signs (for example, the trumpet as a sign of war). But in the passions of the soul we have to take into account the idea of a likeness to the things represented, since passions of the soul designate things naturally, not by institution.
Peri.L2
20. Obiiciunt autem quidam [ostendere volentes] contra hoc quod dicit passiones animae, quas significant voces, esse omnibus easdem.
There are some who object to Aristotle’s position that passions of the soul, which vocal sounds signify, are the same for all men.
Peri.L2
Primo quidem, quia diversi diversas sententias habent de rebus, et ita non videntur esse eaedem apud omnes animae passiones.
Their argument against it is as follows. Different men have different opinions about things; therefore, passions of the soul do not seem to be the same among all men.
Peri.L2
Ad quod respondet Boethius quod Aristoteles hic nominat passiones animae conceptiones intellectus, qui numquam decipitur, et ita oportet eius conceptiones esse apud omnes easdem, quia, si quis a vero discordat, hic non intelligit.
In reply to this object, Boethius says that here Aristotle is using passions of the soul to denote conceptions of the intellect, and since the intellect is never deceived, conceptions of the intellect must be the same among all men. For if someone is at variance with what is true, in this instance he does not understand.
Peri.L2
Sed, quia etiam in intellectu potest esse falsum, secundum quod componit et dividit, non autem secundum quod cognoscit quod quid est, id est essentiam rei, ut dicitur in III De anima, referendum est hoc ad simplices conceptiones intellectus quas voces incomplexae significant, quae sunt eaedem apud omnes, quia, si quis vere intelligit quid est homo, quicumque aliquid aliud [quam hominem] apprehendit, non intelligit hominem. Huiusmodi autem simplices conceptiones intellectus sunt quas primo voces significant; unde dicitur in IV Metaphysicae quod ratio quam significat nomen est definitio. Et ideo signanter dicit: Quorum primorum hae notae sunt, ut scilicet referatur ad primas conceptiones a vocibus primo significatas.
However, since what is false can also be in the intellect, not as it knows what a thing is (that is, a thing’s essence), but as it composes and divides, as is said in On the Soul 3.6, 430a26, Aristotle’s statement should be referred to the simple conceptions of the intellect that are signified by the incomplex vocal sounds, which are the same among all men; for if someone truly understands what man is, whatever else than man he apprehends he does not understand as man. Simple conceptions of the intellect, which vocal sounds first signify, are of this kind. This is why Aristotle says (in Metaphysics 4.4, 1006b4) that the notion which the name signifies is the definition. And this is the reason he expressly says: of which the first of these are signs, namely, so that this will be referred to the first conceptions first signified by vocal sounds.
Peri.L2
21. Sed adhuc obiiciunt aliqui de nominibus aequivocis, in quibus eiusdem vocis non est eadem passio quae significatur apud omnes.
The equivocal name is given as another objection to this position, for in the case of an equivocal name the same vocal sound does not signify the same passion among all men.
Peri.L2
Et respondet ad hoc Porphyrius quod unus homo qui vocem profert ad unam intellectus conceptionem significandam eam refert, et, si alius cui loquitur aliquid aliud intelligat, ille qui loquitur se exponendo faciet quod referet intellectum ad idem.
Porphyry answers this by pointing out that a man who utters a vocal sound intends it to signify one conception of the intellect. If the person to whom he is speaking understands something else by it, if the one who is speaking explains himself, he will make his listener refer his understanding to the same thing.
Peri.L2
Sed melius dicendum est quod intentio Aristotelis non est asserere identitatem conceptionis animae per comparationem ad vocem, ut scilicet unius vocis una sit conceptio, quia voces sunt diversae apud diversos, sed intendit asserere identitatem conceptionum animae per comparationem ad res, quas similiter dicit esse easdem.
It is better to say, however, that it is not Aristotle’s intention to maintain an identity of the conception of the soul in relation to a vocal sound such that there is one conception in relation to one vocal sound, for vocal sounds are different among different peoples. Rather, he intends to maintain an identity of the conceptions of the soul in relation to things, which things he also says are the same.
Peri.L2
22. Tertio, ibi: De his quidem dictum est et cetera, excusat <se> a diligentiori horum consideratione, quia quales sint animae passiones et quomodo sint rerum similitudines, dictum est in libro De anima; non enim hoc pertinet ad logicum negotium, sed ad naturalem.
Third, when he says: this has been discussed (16a5), he excuses himself from a further consideration of these things, for the nature of the passions of the soul and the way in which they are likenesses of things does not pertain to logic but to philosophy of nature, and has already been treated in the book On the Soul.1
Peri.L2
L. 3 (A.1, 16a9–16a18)The diverse signification of vocal soundDe diversa vocum significatione
16a9. Est autem, quemadmodum in anima aliquotiens quidem intellectus sine vero et falso, aliquotiens autem cui iam necesse est horum alterum inesse, sic etiam in voce.
16a9. As sometimes there is thought in the soul without its being true or false, but sometimes it must be one or the other, so it is in vocal sound.
Peri.L3
16a12. Circa compositionem enim et divisionem est veritas falsitasque.
16a12. For in composition and division there is truth and falsity.
Peri.L3
16a13. Nomina igitur ipsa et verba consimilia sunt sine compositione et divisione intellectui, ut ‘homo’ vel ‘album’, quando non additur aliquid; neque enim adhuc verum vel falsum est.
16a13. Names and verbs, then, are like thought without composition or division (for example, “man” and “white” when nothing is added); for neither is yet true or false.
Peri.L3
16a16. Huius autem signum hoc est: ‘hircocervus’ enim significat aliquid, sed quod nondum verum vel falsum sit, si non esse vel non esse addatur vel simpliciter vel secundum tempus.
16a16. A sign of this is that “goat-stag” signifies something, but is neither true nor false unless “to be” or “not to be” is added either absolutely or according to time.
Peri.L3
23. Est autem, quemadmodum in anima, etc. Postquam Philosophus tradidit ordinem significationis vocum, hic agit de diversa vocum significatione, quarum quaedam significant verum et falsum, quaedam non.
As sometimes there is thought. After the Philosopher has treated the order of the signification of vocal sounds, he goes on to discuss a diversity in the signification of vocal sounds—that is, some of them signify the true or the false, others do not.
Peri.L3
Et circa hoc duo facit:
And he does two things about this:
Peri.L3
primo praemittit differentiam;
first, he first states the difference;
Peri.L3
secundo manifestat eam, ibi: Circa compositionem et cetera.
second, he makes it clear, at: for in composition and division there is truth and falsity (16a12; [25]).
Peri.L3
Quia vero conceptiones intellectus praeambulae sunt ordine naturae vocibus quae ad eas exprimendas proferuntur, ideo ex similitudine differentiae quae est circa intellectum assignat differentiam quae est circa significationes vocum, ut scilicet haec manifestatio non solum sit ex simili, sed ex causa quam imitatur effectus.
Now, because in the order of nature, conceptions of the intellect precede vocal sounds, which are uttered to express them, he assigns the difference in respect to the significations of vocal sounds from a likeness to the difference in intellection. Thus the manifestation is from a likeness and at the same time from the cause which the effects imitate.
Peri.L3
24. Est ergo considerandum quod, sicut in principio dictum est, duplex est operatio intellectus, ut traditur in III De anima, in quarum una non invenitur verum et falsum, in altera autem invenitur. Et hoc est quod dicit quod in anima aliquotiens est intellectus sine vero et falso, aliquotiens autem ex necessitate habet alterum istorum; et, quia voces significativae formantur ad exprimendas conceptiones intellectus, ideo ad hoc quod signum conformetur signato, necesse est quod etiam vocum significativarum similiter quaedam significent sine vero et falso, quaedam autem cum vero et falso.
The operation of the intellect is twofold, as was said in the beginning, and as is explained in On the Soul 3.6, 430a26. Now, truth and falsity is found in one of these operations but not in the other. This is what Aristotle says at the beginning of this portion of the text, that is, that in the soul sometimes there is thought without truth and falsity, but sometimes of necessity it has one or the other of these. And since significant vocal sounds are formed to express these conceptions of the intellect, it is necessary that some significant vocal sounds signify without truth and falsity, others with truth and falsity—in order that the sign be conformed to what is signified.
Peri.L3
25. Deinde cum dicit: Circa compositionem enim et divisionem et cetera, manifestat quod dixerat.
Then, when he says: for in composition and division there is truth and falsity (16a12), he manifests what he has just said:
Peri.L3
Et primo quantum ad id quod dixerat de intellectu;
first, with respect to what he has said about thought;
Peri.L3
secundo quantum ad id quod dixerat de assimilatione vocis ad intellectum, ibi: Nomina igitur <ipsa> et verba etc.
second, with respect to what he has said about the likeness of vocal sounds to thought, where he says: names and verbs, then, are like thought (16a13; [33]).
Peri.L3
Ad ostendendum igitur quod intellectus quandoque est sine vero et falso, quandoque autem cum altero horum, dicit primo quod veritas et falsitas est circa compositionem et divisionem.
To show that sometimes there is thought without truth or falsity, and sometimes it is accompanied by one of these, he says first that truth and falsity concern composition and division (16a12).
Peri.L3
Ubi oportet intelligere quod una duarum operationum intellectus est indivisibilium intelligentia, in quantum scilicet intellectus intelligit absolute cuiuscumque rei quidditatem sive essentiam per se ipsam, puta quid est homo vel quid album vel aliud huiusmodi;
To understand this we must note again that one of the two operations of the intellect is the understanding of what is indivisible. The intellect does this when it understands the quiddity or essence of a thing absolutely (for instance, what man is or what white is or what something else of this kind is).
Peri.L3
alia vero operatio intellectus est secundum quod huiusmodi simplicia concepta simul componit et dividit. Dicit ergo quod in hac secunda operatione intellectus, scilicet componentis et dividentis, invenitur veritas et falsitas, relinquens quod in prima operatione non invenitur, ut etiam traditur in III De anima.
The other operation is the one in which it composes and divides simple concepts of this kind. He says that in this second operation of the intellect—that is, composing and dividing—truth and falsity is found, with the conclusion that it is not found in the first, as he also says in On the Soul 3.6, 430a26.
Peri.L3
26. Sed circa hoc primo videtur esse dubium, quia, cum divisio fiat per resolutionem ad indivisibilia sive simplicia, videtur quod, sicut in simplicibus non est veritas vel falsitas, ita nec in divisione.
There seems to be a difficulty about this point, for division is made by resolution to what is indivisible, or simple, and therefore it seems that just as truth and falsity is not in simple things, so neither is it in division.
Peri.L3
Sed dicendum est quod, cum conceptiones intellectus sint similitudines rerum, ea quae circa intellectum sunt dupliciter considerari et nominari possunt:
To answer this it should be pointed out that the conceptions of the intellect are likenesses of things, and therefore the things that are in the intellect can be considered and named in two ways:
Peri.L3
uno modo secundum se,
in one way, according to themselves;
Peri.L3
alio modo secundum considerationes rerum quarum sunt similitudines;
in a second way, according to the nature of the things of which they are the likenesses.
Peri.L3
sicut imago Herculis secundum se quidem dicitur et est cuprum, in quantum autem est similitudo Herculis nominatur homo. Sic etiam, si consideremus ea quae sunt circa intellectum secundum se, semper est compositio ubi est veritas et falsitas, quae nunquam invenitur in intellectu nisi per hoc quod intellectus comparat unum simplicem conceptum alteri;
For just as a statue—say of Hercules—in itself is called and is bronze, but insofar it is a likeness of Hercules is called a man, so if we consider the things that are in the intellect in themselves, there is always composition where there is truth and falsity, for they are never found in the intellect except as it compares one simple concept with another.
Peri.L3
sed, si referatur ad rem, quandoque dicitur compositio, quandoque dicitur divisio: compositio quidem quando unus intellectus comparat unum conceptum alteri quasi apprehendens coniunctionem aut identitatem rerum quarum sunt conceptiones; divisio autem quando sic comparat unum conceptum alteri ut apprehendat res esse divisas. Et per hunc etiam modum in vocibus affirmatio dicitur compositio in quantum ex parte rei significat <coniunctionem>, negatio vero dicitur divisio in quantum significat rerum separationem.
But if the composition is referred to reality, it is sometimes called composition, sometimes division: composition when the intellect compares one concept to another as though apprehending a conjunction or identity of the things of which they are conceptions; division when it so compares one concept with another that it apprehends the things to be diverse. In vocal sound, therefore, affirmation is called composition inasmuch as it signifies a conjunction on the part of the thing, and negation is called division inasmuch as it signifies the separation of things.
Peri.L3
27. Ulterius autem videtur quod non solum in compositione et divisione veritas consistat.
There is still another objection in relation to this point. It seems that truth is not in composition and division alone.
Peri.L3
Primo quidem quia etiam res dicitur vera vel falsa, sicut dicitur aurum verum vel falsum. Dicitur etiam quod ens et verum convertuntur. Unde videtur quod etiam simplex conceptio intellectus, quae est similitudo rei, non careat veritate et falsitate.
First, because a thing is also said to be true or false, as gold is said to be true gold or false gold. Also, being and true are said to be convertible. It seems, therefore, that the simple conception of the intellect, which is a likeness of the thing, also has truth and falsity.
Peri.L3
Praeterea, Philosophus dicit in libro De anima quod sensus propriorum sensibilium semper verus est; sensus autem non componit vel dividit; non ergo in sola compositione et divisione est veritas.
Again, the Philosopher says in his book On the Soul,1 that the sensation of proper sensibles is always true. But the sense does not compose or divide. Therefore, truth is not in composition and division exclusively.
Peri.L3.arg1
Idem, in intellectu divino nulla est compositio, ut probatur in XI Metaphysicae; et tamen ibi <est> prima et summa veritas; non ergo veritas est solum circa compositionem et divisionem.
Moreover, in the divine intellect there is no composition, as is proved in Metaphysics 9.9, 1074b15–1075a11. But the first and highest truth is in the divine intellect. Therefore, truth is not in composition and division exclusively.
Peri.L3
28. Ad huius igitur evidentiam considerandum est
To answer these difficulties the following considerations are necessary.
Peri.L3
quod veritas in aliquo invenitur dupliciter:
Truth is found in something in two ways:
Peri.L3
uno modo sicut in eo quod est verum;
as it is in that which is true,
Peri.L3
alio modo sicut in dicente vel cognoscente verum;
and as it is in the one speaking or knowing truth.
Peri.L3
invenitur autem veritas sicut in eo quod est verum tam in simplicibus quam in compositis, sed sicut in dicente vel cognoscente verum, non invenitur nisi secundum compositionem et divisionem. Quod quidem sic patet.
Truth as it is in that which is true is found in both simple things and composite things, but truth in the one speaking or knowing truth is found only according to composition and division. This will become clear in what follows.
Peri.L3
29. Verum enim, ut Philosophus dicit in VI Ethicorum, est bonum intellectus, unde, de quocumque dicatur verum, oportet quod sit per respectum ad intellectum.
Truth, as the Philosopher says in Ethics 6.2, 1139a28–30, is the good of the intellect. Hence, anything that is said to be true is such by reference to intellect.
Peri.L3
[Comparantur autem ad intellectum voces quidem sicut signa, res autem sicut ea quorum intellectus sunt similitudines.]
[Now, vocal sounds are related to thought as signs, but things are related to thought as that of which thoughts are likenesses.]
Peri.L3
Considerandum autem quod aliqua res comparatur ad intellectum dupliciter.
It must be noted, however, that a thing is related to thought in two ways.
Peri.L3
Uno modo sicut mensura ad mensuratum, et sic comparantur res naturales ad intellectum speculativum humanum. Et ideo intellectus dicitur verus secundum quod conformatur rei, falsus autem secundum quod discordat a re. Res autem naturalis non dicitur esse vera per comparationem ad intellectum nostrum, sicut posuerunt quidam antiqui Naturales, existimantes rerum veritatem esse solum in hoc quod est videri: secundum hoc enim sequeretur quod contradictoria essent simul vera, quia contradictoria cadunt sub diversorum opinionibus. Dicitur tamen aliqua res vera vel falsa per comparationem ad intellectum nostrum, non essentialiter vel formaliter, sed effective, in quantum scilicet nata est facere de se veram vel falsam existimationem; et secundum hoc dicitur aurum verum vel falsum.
In one way, as the measure is related to the measured, and this is the way natural things are related to the human speculative intellect. Thus thought is said to be true insofar as it is conformed to the thing, but false insofar as it is not in conformity with the thing. However, a natural thing is not said to be true in relation to our thought in the way it was taught by certain ancient natural philosophers who supposed the truth of things to be only in what they seemed to be. According to this view, it would follow that contradictories could be at once true, since the opinions of different men can be contradictory. Nevertheless, some things are said to be true or false in relation to our thought—not essentially or formally, but effectively—insofar as they are so constituted naturally as to cause a true or false estimation of themselves. It is in this way that gold is said to be true or false.
Peri.L3
Alio vero modo res comparantur ad intellectum sicut mensuratum ad mensuram, ut patet in intellectu practico, qui est causa rerum. Unde opus artificis dicitur esse verum in quantum attingit ad rationem artis, falsum vero in quantum deficit a ratione artis.
In another way, things are compared to thought as measured to the measure, as is evident in the practical intellect, which is a cause of things. In this way, the work of an artisan is said to be true insofar as it achieves the conception in the mind of the artist, and false insofar as it falls short of that conception.
Peri.L3
30. Et quia omnia, etiam naturalia, comparantur ad intellectum divinum sicut artificialia ad artem, consequens est ut quaelibet res dicatur esse vera secundum quod habet propriam formam secundum quam imitatur artem divinam: nam falsum aurum est verum aurichalcum. Et hoc modo ens et verum convertuntur, quia quaelibet res naturalis per suam formam arti divinae conformatur. Unde et Philosophus in I Physicorum formam nominat quicquam divinum.
Now, all natural things are related to the divine intellect as artifacts to art, and therefore a thing is said to be true insofar as it has its own form according to which it represents divine art. False gold, for example, is true copper. It is in terms of this that being and true are converted, since any natural thing is conformed to divine art through its form. For this reason, the Philosopher says1 that form is something divine.
Peri.L3
31. Et, sicut dicitur res vera per comparationem ad suam mensuram, ita etiam et sensus vel intellectus, cuius mensura est res extra animam: unde sensus dicitur verus quando per formam <suam> conformatur rei extra animam existenti. Et sic intelligitur quod sensus proprii sensibilis sit verus. Et hoc etiam modo intellectus apprehendens quod quid est absque compositione et divisione semper est verus, ut dicitur in III De anima.
And just as a thing is said to be true by comparison to its measure, so also is sensation or thought, whose measure is the thing outside of the soul. Accordingly, sensation is said to be true when the sense is in conformity with the thing existing outside of the a soul through its form. It is in this way that the sensation of proper sensibles is true, and the intellect apprehending what a thing is (apart from composition and division) is always true, as is said in On the Soul.1
Peri.L3
Est autem considerandum quod, quamvis sensus proprii obiecti sit verus, non tamen cognoscit hoc verum: non enim potest cognoscere habitudinem conformitatis sui ad rem, sed solam rem apprehendit; intellectus autem potest huiusmodi habitudinem conformitatis cognoscere, et ideo solus intellectus potest cognoscere veritatem: unde et Philosophus dicit in VI Metaphysicae quod veritas est solum in mente, scilicet sicut in cognoscente veritatem. Cognoscere autem praedictam conformitatis habitudinem nihil est aliud quam iudicare ita esse in re vel non esse, quod est componere et dividere, et ideo intellectus non cognoscit veritatem nisi componendo vel dividendo per suum iudicium. Quod quidem iudicium, si consonet rebus, erit verum, puta cum intellectus iudicat rem esse quae est, vel non esse quae non est, falsum autem quando dissonat a re, puta cum iudicat non esse quod est vel esse quod non est. Unde patet quod veritas et falsitas sicut in cognoscente et dicente non est nisi circa compositionem et divisionem. Et hoc modo hic Philosophus loquitur.
It should be noted, however, that although the sensation of the proper object is true, the sense does not perceive the sensation to be true, for it cannot know its relationship of conformity with the thing, but only apprehends the thing. The intellect, on the other hand, can know its relationship of conformity; therefore, only the intellect can know truth. This is the reason the Philosopher says in Metaphysics 6.4, 1027b26 that truth is only in the mind, that is to say, in knowing truth. To know this relationship of conformity is to judge that a thing is such or is not, which is to compose and divide; therefore, the intellect does not know truth except by composing and dividing through its judgment. The judgment will be true if it is in accordance with things—that is, when it judges a thing to be what it is, or not to be what it is not. The judgment will be false when it is not in accordance with the thing, that is, when it judges that which is, to be not, or that which is not, to be. It is evident from this that truth and falsity as it is in the one knowing and speaking is had only in composition and division.
Peri.L3
[Et, quia voces sunt signa intellectuum, erit vox vera quae significat verum intellectum, falsa autem quae significat falsum intellectum, quamvis vox, in quantum est res quaedam, dicatur vera sicut et aliae res; unde haec vox: ‘homo est asinus’, est vera vox et verum signum, sed, quia est signum falsi, ideo dicitur falsa.]
[This is what the Philosopher is speaking of here. And since vocal sounds are signs of thought, the vocal sound which signifies true thought will be true, and the one which signifies false thought will be false, although vocal sound insofar as it is a real thing is said to be true in the same way other things are. Thus the vocal sound “man is an ass” is a true vocal sound and a true sign, but because it is a sign of something false, it is said to be false.]
Peri.L3
32. Sciendum est autem quod Philosophus hic de veritate loquitur secundum quod pertinet ad intellectum humanum, qui iudicat de conformitate rerum <et> intellectus componendo et dividendo. Sed iudicium intellectus divini de hoc est absque compositione et divisione, quia, sicut et intellectus noster intelligit materialia immaterialiter, ita etiam intellectus divinus cognoscit compositionem et divisionem simpliciter.
It should be noted that the Philosopher is speaking of truth here as it relates to the human intellect, which judges of the conformity of things and thought by composing and dividing. However, the judgment of the divine intellect concerning this is without composition and division, for just as our intellect understands material things immaterially, so the divine intellect knows composition and division simply.
Peri.L3
33. Deinde cum dicit: Nomina igitur ipsa et verba et cetera, manifestat quod dixerat de similitudine vocis ad intellectum.
When he says: names and verbs, then, are like thought without composition or division (16a13), he makes clear what he has said about the likeness of vocal sounds to thought.
Peri.L3
Et primo manifestat propositum;
First, he manifests his intention;
Peri.L3
secundo probat per signum, ibi: Huius autem signum, et cetera.
second, he proves it by a sign when he says: a sign of this (16a16; [35]).
Peri.L3
Concludit ergo ex praemissis quod, cum solum circa compositionem et divisionem sit veritas et falsitas in intellectu, consequens est quod ipsa nomina et verba, divisim accepta, assimilentur intellectui qui est sine compositione et divisione, sicut cum dico ‘homo’ vel ‘album’, si nihil aliud addatur: non enim adhuc est verum vel falsum (sed postea, quando additur esse vel non esse, fit verum vel falsum).
Here he concludes from what has been said that since there is truth and falsity in the intellect only when there is composition or division, it follows that names and verbs, taken separately, are like thought which is without composition and division, as when I say “man” or “white” and nothing else is added. For these are neither true nor false at this point, but when “to be” or “not to be” is added, they become true or false.
Peri.L3
34. Sed nec est instantia de eo qui per unicum nomen veram responsionem dat ad interrogationem factam, ut cum quaerenti: ‘Quid natat in mari?’, aliquis respondet: ‘Piscis’; nam intelligitur verbum quod fuit in interrogatione positum.
The case of someone giving a single name as a true response to a question is not an instance that can be raised against this position (for example, if someone asks, “What swims in the sea?” and someone answers, “Fish”). This is not opposed to the position Aristotle is taking here, for the verb that was posited in the question is understood.
Peri.L3
Et, sicut nomen per se positum non significat verum vel falsum, ita nec verbum per se dictum, nec est instantia de verbis primae et secundae personae, et de verbis exceptae actionis, quia in his intelligitur determinatus nominativus; unde est implicita compositio, licet non explicita.
And just as the name said by itself does not signify truth or falsity, so neither does the verb said by itself. The verbs of the first and second person and the intransitive verb are not instances opposed to this position either, for in these a particular and determined nominative is understood. Consequently, there is implicit composition, though not explicit.
Peri.L3
35. Deinde cum dicit: Huius autem signum et cetera, inducit signum ex nomine composito, scilicet hircocervus, quod componitur ex hirco et cervus, quod in Graeco dicitur tragelaphos: nam tragos est hircus et laphos cervus. Huiusmodi enim nomina significant aliquid, scilicet quosdam conceptus simplices, licet rerum compositarum; et ideo non est verum vel falsum, nisi quando additur esse vel non esse, vel secundum praesens tempus, quod est esse vel non esse in actu, et ideo hoc dicit esse simpliciter, vel secundum tempus praeteritum aut futurum, quod non est esse simpliciter, sed secundum quid, ut cum dicitur aliquid fuisse vel futurum esse. Signanter autem utitur exemplo ex nomine significante quod non est in rerum natura, in quo statim falsitas appareret, si sine compositione et divisione posset esse verum vel falsum.
Then, when he says: a sign of this (16a16), he introduces as a sign the composite name “goat-stag,” from “goat” and “stag.” In Greek, the word is “tragelaphos,” from “tragos,” meaning goat, and “elaphos,” meaning stag. Now, names of this kind signify something—namely, certain simple concepts (although the things they signify are composite)—and therefore are not true or false unless “to be” or “not to be” is added, by which a judgment of the intellect is expressed. The “to be” or “not to be” can be added either according to present time, which is to be or not to be in act (and for this reason is to be simply); or according to time, either past or future, which is to be relatively, not simply (as when we say that something has been or will be). Notice that Aristotle expressly uses as an example here a name signifying something that does not exist in reality, in which fictiveness is immediately evident, and which cannot be true or false without composition and division.
Peri.L3
L. 4 (Α.2, 16a19–16b5)The nameDe nomine
16a19. Nomen ergo est vox significativa secundum placitum sine tempore, cuius nulla pars est significativa separata.
16a19. A name, then, is a vocal sound significant by convention, without time, no part of which is significant separately.
Peri.L4
16a21. In nomine enim quod est ‘equiferus’, ‘ferus’ nihil per se significat, quemadmodum in oratione quae est, ‘equus ferus.’
16a21. For in the name “Campbell,” the part “bell” signifies nothing as such, although in the expression “camp-bell” it does.
Peri.L4
16a22. At vero non quemadmodum in simplicibus nominibus, sic se habet et in compositis; in illis enim nullo modo pars significativa est, in his autem vult quidem, sed nullius separatim, ut in eo quod est ‘equiferus’.
16a22. However, the case is not exactly the same in simple names and composite names, for in the former the part is in no way significant, but in the latter the part has meaning, but not apart from the word, as “fast” in “breakfast.”
Peri.L4
16a27. Secundum placitum vero, quoniam naturaliter nominum nihil est, sed quando fit nota. Nam designant et illitterati soni, ut ferarum, quorum nihil est nomen.
16a27. “By convention” is added because nothing is by nature a name, but it is a name when it is made a sign. For unlettered sounds (such as those of the brutes) designate, but none of them is a name.
Peri.L4
16a30. ‘Non homo’ vero non est nomen. At vero nec positum est nomen quo illud oporteat appellari, neque enim oratio aut negatio est, sed sit nomen infinitum.
16a29. “Non-man,” however, is not a name. No name has been imposed to designate this—for it is neither speech nor a negation—but let us call it an infinite name.
Peri.L4
16a33. ‘Catonis’ autem vel ‘Catoni’ et quaecumque talia sunt, non sunt nomina, sed casus nominis.
16a32. “Of Cato” and “to Cato” and all such expressions are not names but modes of names.
Peri.L4
16b1. Ratio autem eius est in aliis quidem eadem, sed differt quoniam, cum ‘est’ vel ‘fuit’ vel ‘erit’ adiunctum, neque verum neque falsum est, nomen vero semper: ut ‘Catonis est’ vel ‘non est’. Nondum enim aliquid neque verum dicit neque falsum.
16b1. The definition of these is the same in all other respects as that of the name itself, but in conjunction with “is” or “has been” or “will be,” they are not true or false. But if one of these is added to a name, there is always truth or falsity; for example, “of Cato is” or “is not” are neither true nor false.
Peri.L4
36. Nomen ergo est vox significativa et cetera. Postquam Philosophus determinavit de ordine significationis vocum, hic accedit ad determinandum de ipsis vocibus significativis.
A name, then, is a significant vocal sound. Having determined the order of the signification of vocal sounds, the Philosopher begins here to establish the definitions of the significant vocal sounds.
Peri.L4
Et quia principaliter intendit de enuntiatione, quae est subiectum huius libri, in qualibet autem scientia oportet praenoscere principia subiecti, ideo primo determinat de principiis enuntiationis; secundo de ipsa enuntiatione, ibi: Enuntiativa vero non omnis et cetera.
His principal intention is to establish what an enunciation is—which is the subject of this book—but since in any science the principles of the subject must be known first, he begins with the principles of the enunciation, and then establishes what an enunciation is where he says: yet not all speech is enunciative (17a2; [82]).
Peri.L4
Circa primum duo facit:
About the first, he does two things:
Peri.L4
primo enim determinat principia quasi materialia enuntiationis, scilicet partes integrales ipsius;
first, he determines the nature of the quasi-material principles (that is, its integral parts);
Peri.L4
secundo determinat principium formale, scilicet orationem, quae est enuntiationis genus, ibi: Oratio est vox significativa et cetera.
second, the formal principle, namely, speech, which is the genus of the enunciation, at: speech is significant vocal sound (16b26; [74]).
Peri.L4
Circa primum duo facit:
About the first he does two things:
Peri.L4
primo determinat de nomine, quod significat substantiam rei;
first, he establishes that a name signifies the substance of a thing;
Peri.L4
secundo determinat de verbo, quod significat actionem vel passionem procedentem a re, ibi: Verbum <autem> est quod consignificat tempus etc.
second, that the verb signifies action or passion proceeding from a thing, at: the verb is that which signifies with time (16b6; [52]).
Peri.L4
Circa primum tria facit:
About the first he does three things:
Peri.L4
primo definit nomen;
first, he defines the name;
Peri.L4
secundo definitionem exponit, ibi: In nomine enim quod est ‘equiferus’ etc.;
second, he explains the definition, at: for in the name “Campbell” (16a21; [44]);
Peri.L4
tertio excludit quaedam quae perfecte rationem nominis non habent, ibi: ‘Non homo’ vero non est nomen et cetera.
third, he excludes certain things which do not have the definition of the name perfectly, at: “non-man,” however, is not a name (16a29; [47]).
Peri.L4
37. Circa primum considerandum est quod definitio ideo dicitur terminus quia includit totaliter rem, ita scilicet quod nihil rei est extra definitionem, cui scilicet definitio non conveniat, nec aliquid aliud est infra definitionem, cui scilicet definitio conveniat.
It should be noted in relation to defining the name that a definition is said to be a limit because it includes a thing totally, so that nothing of the thing is outside of the definition (that is, there is nothing of the thing to which the definition does not belong); nor is any other thing under the definition, namely, the definition belongs to no other thing.
Peri.L4
38. Et ideo quinque ponit in definitione nominis.
Therefore, Aristotle posits five parts in the definition of the name.
Peri.L4
Primo enim ponitur vox per modum generis, per quod distinguitur nomen ab omnibus sonis qui non sunt voces; nam vox est sonus ab ore animalis prolatus cum imaginatione quadam, ut dicitur in II De anima.
Vocal sound is first given as the genus. This distinguishes the name from all sounds that are not vocal, for vocal sound is sound produced from the mouth of an animal and involves a certain kind of mental image, as is said in On the Soul 2.8, 420b30–34.
Peri.L4
Additur autem prima differentia, significativa, ad differentiam quarundam vocum non significantium, sive sit litterata et articulata, sicut ‘biltrix’, sive vox inlitterata et non articulata, sicut sibilus pro nihilo factus. Et, quia de significatione vocum in superioribus actum est, ideo ex praemissis concludit quod nomen est vox significativa.
Second, he adds the first difference, significant, which differentiates the name from any non-significant vocal sound, whether lettered and articulated (such as “biltrix”), or non-lettered and non-articulated (like as a hissing for no reason). Now, since he has already determined the signification of vocal sounds, he concludes from what has been established that a name is a significant vocal sound.
Peri.L4
39. Sed, cum vox sit quaedam res naturalis, nomen autem non est aliquid naturale, sed ab hominibus institutum, videtur quod non debeat genus nominis ponere vocem, quod est naturale, sed magis signum, quod est ex institutione, ut diceretur: ‘Nomen est signum vocale’, sicut etiam convenientius definiretur scutella, si quis diceret quod est <calix ligneus, quam si quis diceret quod est> lignum in forma calicis.
Now, vocal sound is a natural thing, but a name is not natural but instituted by men. It seems, therefore, that Aristotle should have taken “sign,” which is from institution, as the genus of the name, rather than “vocal sound,” which is from nature. Then the definition would be: “A name is a vocal sign,” just as a salver would be more suitably defined as a wooden dish than as wood formed into a dish.
Peri.L4
40. Sed dicendum quod artificialia sunt quidem in genere substantiae ex parte materiae, in genere autem accidentium ex parte formae: nam formae artificialium accidentia sunt; nomen ergo significat formam accidentalem ut concretam subiecto.
It should be noted, however, that while it is true that, on the part of their matter, artificial things are in the genus of substance, they are in the genus of accident on the part of their form, since the forms of artificial things are accidents. A name, therefore, signifies an accidental form made concrete in a subject.
Peri.L4
Cum autem in definitione omnium accidentium oporteat poni subiectum, necesse est quod, si qua nomina accidens in abstracto significant, quod in eorum definitione ponatur accidens in recto quasi genus, et subiectum in obliquo quasi differentia, ut cum <dicitur>: ‘Simitas est curvitas nasi’; si qua vero nomina accidens significant in concreto, in eorum definitione ponitur materia vel subiectum quasi genus, et accidens quasi differentia, ut cum dicitur: ‘Simum est nasus curvus’.
Now, the subject must be posited in the definition of every accident; thus, when names signify an accident in the abstract, the accident has to be posited directly (that is, in the nominative case) as a quasi-genus in their definition, and the subject posited obliquely1 as a quasi-difference—for example, as when we define snubness as “curvedness of the nose.” But when names signify an accident in the concrete, the matter or subject has to be posited in their definition as a quasi-genus and the accident as a quasi-difference, as when we say that a snub nose is a curved nose.
Peri.L4
Si igitur nomina rerum artificialium significant formas accidentales ut concretas subiectis naturalibus, convenientius est ut in eorum definitione ponatur res naturalis quasi genus, ut dicamus quod scutella est lignum figuratum, et similiter <quod> nomen est vox significativa. Secus autem esset si nomina artificialium acciperentur quasi significantia ipsas formas artificiales in abstracto.
Accordingly, if the names of artificial things signify accidental forms as made concrete in natural subjects, then it is more appropriate to posit the natural thing in their definition as a quasi-genus. We would say, therefore, that a salver is shaped wood, and likewise, that a name is a significant vocal sound. It would be another matter if names of artificial things were taken as signifying artificial forms in the abstract.
Peri.L4
41. Tertio ponit secundam differentiam, cum dicit: secundum placitum, id est secundum institutionem humanam a beneplacito hominis procedentem, et per hoc differt nomen a vocibus significantibus naturaliter, sicut sunt gemitus infirmorum et voces brutorum animalium.
Third, he gives the second difference, which is by convention, that is, according to human institution deriving from the will of man. This differentiates names from vocal sounds signifying naturally, such as the groans of the sick and the vocal sounds of brute animals.
Peri.L4
42. Quarto ponit tertiam differentiam, scilicet sine tempore, per quod differt nomen a verbo.
Fourth, he gives the third difference, namely, without time, which differentiates the name from the verb.
Peri.L4
Sed hoc videtur falsum esse, quia hoc nomen ‘dies’ vel ‘annus’ significat tempus.
This, however, seems to be false, for the name “day” or “year” signifies time.
Peri.L4
Sed dicendum quod circa tempus tria possunt considerari.
But there are three things that can be considered with respect to time:
Peri.L4
Primo quidem ipsum tempus secundum quod est res quaedam, et sic potest significari a nomine, sicut quaelibet alia res.
first, time itself, as it is a certain kind of thing or reality, and then it can be signified by a name just like any other thing;
Peri.L4
Alio modo potest considerari id quod tempore mensuratur in quantum huiusmodi; et quia id quod primo et principaliter tempore mensuratur est motus, in quo consistit actio et passio, ideo verbum, quod significat actionem et passionem, significat cum tempore; substantia autem secundum se considerata, prout significatur per nomen et pronomen, non habet in quantum huiusmodi ut tempore mensuretur, sed solum secundum quod subicitur motui, <prout> per participium significatur; et ideo verbum et participium significant cum tempore, non autem nomen et pronomen.
second, that which is measured by time, insofar as it is measured by time. (Motion, which consists of action and passion, is what is measured first and principally by time, and therefore the verb, which signifies action and passion, signifies with time. Substance considered in itself, which a name or a pronoun signifies, is not as such measured by time, but only insofar as it is subjected to motion, and this the participle signifies. The verb and the participle, therefore, signify with time, but not the name and pronoun.)
Peri.L4
Tertio modo potest considerari ipsa habitudo temporis mensurantis, quod significatur per adverbium temporis, ut ‘cras’, ‘heri’, et huiusmodi.
The third thing that can be considered is the very relationship of time as it measures. This is signified by adverbs of time such as “tomorrow,” “yesterday,” and others of this kind.
Peri.L4
43. Quinto ponit quartam differentiam, cum subdit: cuius nulla pars est significativa separata, scilicet a toto nomine, cooperatur tamen ad significationem nominis secundum quod est in toto (quod ideo est quia significatio est quasi forma nominis, nulla autem pars separata habet formam totius, sicut manus separata ab homine non habet formam humanam); et per hoc distinguitur nomen ab oratione, quae etiam quandoque significat sine tempore, ut cum dicitur: ‘Homo iustus’.
Fifth, he gives the fourth difference, no part of which is significant separately, that is, separated from the whole name, but each is related to the signification of the name according to its place in the whole. The reason for this is that signification is a quasi-form of the name. But no separated part has the form of the whole, just as the hand separated from the man does not have the human form. This difference distinguishes the name from speech, some parts of which signify separately—for example, in the phrase “just man.”
Peri.L4
44. Deinde cum dicit: In nomine enim quod est ‘equiferus’ et cetera, manifestat praemissam definitionem.
Then, when he says: for in the name “Campbell,“ he explains the definition.
Peri.L4
Et primo quantum ad ultimam particulam;
First, he explains the last part of the definition;
Peri.L4
secundo quantum ad tertiam, ibi: Secundum placitum vero et cetera.
second, the third part, by convention.
Peri.L4
Nam primae duae particulae manifestae sunt ex praemissis, quarta vero particula, scilicet sine tempore, manifestatur in sequentibus, in tractatu de verbo.
The first two parts were explained in what preceded, and the fourth part, without time, will be explained later in the section on the verb.
Peri.L4
Circa primum duo facit: primo manifestat propositum per nomina composita;
First, he explains the last part by means of a composite name;
Peri.L4
secundo ostendit circa hoc differentiam inter nomina composita et simplicia, ibi: At vero non quemadmodum et cetera.
second, he shows what the difference is between simple and composite names where he says: however, the case is not exactly the same (16a22; [45]).
Peri.L4
Manifestat ergo primo quod pars nominis separata nihil significat, per nomina composita, in quibus hoc minus videtur. In hoc enim nomine quod est ‘equiferus’, haec pars ‘ferus’ nihil per se significat, sicut significat in hac oratione quae est ‘equus ferus’.
First, then, he shows that a part separated from a name signifies nothing (16a21). To do this, he uses a composite name because the point is more striking there. For in this name “Campbell” the part “bell” signifies nothing of itself, although it does signify something in the phrase “camp-bell.“
Peri.L4
Cuius ratio est quia unum nomen imponitur ad significandum unum simplicem intellectum; aliud autem <est> id a quo imponitur nomen ad significandum, ab eo quod nomen significat; sicut hoc nomen ‘lapis’ imponitur a laesione pedis, quod non significat, ad significandum conceptum cuiusdam rei. Et inde est quod pars nominis compositi, quod imponitur ad significandum conceptum simplicem, non significat partem conceptionis compositae a qua imponitur nomen ad significandum. Sed oratio significat ipsam conceptionem compositam; unde pars orationis significat partem conceptionis compositae.
This is because one name is imposed to signify one simple conception, but that from which a name is imposed to signify is different from that which a name signifies. For example, the name “pedigree”1 is imposed from “pedis” and “grus,”2 which it does not signify, to signify the concept of a certain thing. Hence, a part of the composite name—which composite name is imposed to signify a simple concept—does not signify a part of the composite conception from which the name is imposed to signify. Speech, on the other hand, does signify a composite conception. Hence, a part of speech signifies a part of the composite conception.
Peri.L4
45. Deinde cum dicit: At vero et cetera, ostendit quantum ad hoc differentiam inter nomina simplicia et composita.
When he says: however, the case is not exactly the same (16a22), he shows that there is a difference between simple and composite names in regard to their parts not signifying separately.
Peri.L4
Et dicit quod non ita se habet in nominibus simplicibus compositis, quia in simplicibus nullo modo pars est significativa, neque secundum veritatem neque secundum apparentiam; sed in compositis vult quidem, id est apparentiam habet significandi, nihil tamen pars eius significat, ut dictum est de hoc nomine ‘equiferus’.
And he says that simple names are not the same as composite names in this respect, because in simple names a part is in no way significant, either according to truth or according to appearance, but in composite names the part has meaning, that is, has the appearance of signifying; yet a part of it signifies nothing, as is said of the name breakfast.
Peri.L4
Huius autem differentiae ratio est quia nomen simplex, sicut imponitur ad significandum conceptum simplicem, ita etiam imponitur ad significandum ab aliquo simplici conceptu; nomen autem <compositum> imponitur a composita conceptione, ex qua habet apparentiam quod pars eius significat.
This is because the simple name is imposed to signify a simple concept and is also imposed from a simple concept, but the composite name is imposed from a composite conception, and hence has the appearance that a part of it signifies.
Peri.L4
46. Deinde cum dicit: Secundum placitum vero et cetera, manifestat tertiam partem praedictae definitionis.
Then when he says: “by convention” is added (16a26), he explains the third part of the definition.
Peri.L4
Et dicit quod ideo dictum est quod nomen significat secundum placitum, quia nullum nomen est naturaliter. Ex hoc enim est nomen, quod significat; non autem significat naturaliter, sed ex institutione. Et hoc est quod subdit: sed quando fit nota, id est quando imponitur ad significandum: id enim quod naturaliter significat, non fit, sed naturaliter est signum. Et hoc significari dicit per illitteratos sonos ferarum, qui scilicet litteris significari non possunt; et dicit potius ‘sonos’ quam ‘voces’, quia quaedam animalia non habent vocem eo quod carent pulmone, sed tamen quibusdam sonis proprias passiones naturaliter significant; nihil autem horum sonorum est nomen. Ex quo manifeste datur intelligi quod nomen non significat naturaliter.
He says that the reason the name is said to signify by convention is that no name exists naturally. For it is a name because it signifies; however, it does not signify naturally, but by institution. He adds this when he says: but it is a name when it is made a sign, that is, when it is imposed to signify. For that which signifies naturally does not become a sign, but is a sign naturally. He explains this when he says: for unlettered sounds, such as those of the brutes, designate, that is, since they cannot be signified by letters. He says “sounds” rather than “vocal sounds” because some animals—those without lungs—do not have vocal sounds. Such animals signify proper passions by some kind of non-vocal sound which signifies naturally. But none of these sounds of the brutes is a name. We are given to understand from this that a name does not signify naturally.
Peri.L4
47. Sciendum tamen est quod circa hoc diversa fuit quorumdam opinio. Quidam enim dixerunt quod nomina nullo modo naturaliter significant, nec differt quae res quo nomine significentur. Alii vero dixerunt quod nomina omnino naturaliter significant, quasi nomina sint naturales similitudines rerum. Quidam vero dixerunt quod nomina non naturaliter significant quantum ad hoc quod eorum significatio non est a natura, ut Aristoteles hic intendit, quantum vero ad hoc naturaliter significant quod eorum significatio congruit naturis rerum, ut Plato dixit; nec obstat quod una res multis nominibus significatur, quia unius rei possunt esse multae similitudines, et similiter ex diversis proprietatibus possunt uni rei multa diversa nomina imponi.
However, there were diverse opinions about this. Some men said that names in no way signify naturally and that it makes no difference which things are signified by which names. Others said that names signify naturally in every way, as if names were natural likenesses of things. Still others said names do not signify naturally, that is, insofar as their signification is not from nature, as Aristotle maintains here, but that names do signify naturally in the sense that their signification corresponds to the natures of things, as Plato held. The fact that one thing is signified by many names is not in opposition to Aristotle’s position here, for there can be many likenesses of one thing; similarly, from diverse properties many diverse names can be imposed on one thing.
Peri.L4
Non est autem intelligendum quod dicit: quorum nihil est nomen, quasi soni animalium non habeant nomina: nominantur enim quibusdam nominibus, sicut dicitur rugitus leonum et mugitus bovum; sed quia nullus talis sonus est nomen, ut dictum est.
When Aristotle says, but none of them is a name, he does not mean that the sounds of animals are not named, for we do have names for them. For example, “roaring” is said of the sound made by a lion, and “lowing” of that of a cow. What he means is that no such sound is a name.
Peri.L4
48. Deinde cum dicit: ‘Non homo’ vero et cetera, excludit quaedam a nominis ratione.
Then when he says: “non-man,” however (16a29), he points out that certain things do not have the nature of a name.
Peri.L4
Et primo, nomen infinitum;
First, he excludes the infinite name;
Peri.L4
secundo casus nominum, ibi: ‘Catonis’ autem vel ‘Catoni’ et cetera.
second, the cases of the name where he says: “of Cato” and “to Cato” (16a32).
Peri.L4
Dicit ergo primo quod ‘non homo’ non est nomen. Omne enim nomen significat aliquam naturam determinatam, ut ‘homo’; aut personam determinatam, ut pronomen; aut utrumque determinatum, ut ‘Socrates’. Sed hoc quod dico ‘non homo’ neque determinatam naturam neque determinatam personam significat: imponitur enim a negatione hominis, quae aequaliter dicitur de ente et non ente; unde et ‘non homo’ potest dici indifferenter et de eo quod non est in rerum natura, ut si dicamus: ‘Chimaera est ‘non homo,’ et de eo quod est in rerum natura, sicut cum dicitur: ‘Equus est ‘non homo’’. Si autem imponeretur a privatione, requireret subiectum ad minus existens; sed quia imponitur a negatione, potest dici de ente et de non ente, ut Boethius et Ammonius dicunt. Quia tamen significat per modum nominis, quod potest subiici et praedicari, requiritur ad minus suppositum in apprehensione. Non autem erat nomen positum tempore Aristotelis, sub quo huiusmodi dictiones concluderentur: non enim est oratio, quia pars eius non significat aliquid separata, sicut nec in nominibus compositis; similiter autem non est negatio, id est negativa oratio, quia huiusmodi oratio superaddit negationem affirmationi, quod non contingit hic; et ideo novum nomen imponit huiusmodi dictioni, vocans eam nomen infinitum, propter indeterminationem significationis, ut dictum est.
He says that “non-man,” however, is not a name (16a29) because every name signifies some determinate nature, for example, “man,” or a determinate person in the case of the pronoun, or both determinately, as in “Socrates.” But when we say “non-man” it signifies neither a determinate nature nor a determinate person, because it is imposed from the negation of man, which negation is predicated equally of being and non-being. Consequently, “non-man” can be said indifferently both of that which does not exist in reality, as in “a chimera is non-man” and of that which does exist in reality, as in “a horse is non-man.” Now, if the infinite name were imposed from a privation it would require at least an existing subject, but since it is imposed from a negation, it can be predicated of being and non-being, as Boethius and Ammonius say. However, since it signifies in the mode of a name, and can therefore be subjected and predicated, a suppositum is required at least in apprehension. In the time of Aristotle there was no name for words of this kind. They are not speech since a part of such a word does not signify something separately, just as a part of a composite name does not signify separately; and they are not negations, that is, negative speech, for speech of this kind adds negation to affirmation, which is not the case here. Therefore he imposes a new name for words of this kind, the infinite name, because of the indetermination of signification, as has been said.
Peri.L4
49. Deinde cum dicit: ‘Catonis’ autem vel ‘Catoni’ et cetera, excludit casus nominis.
Then when he says: “of Cato” and “to Cato” (16a32), he excludes the cases of names from the nature of the name.
Peri.L4
Et dicit quod ‘Catonis’ vel ‘Catoni’ et alia huiusmodi non sunt nomina, sed solus nominativus dicitur principaliter nomen, per quem facta est impositio nominis ad aliquid significandum; huiusmodi autem obliqui vocantur casus nominis, quia quasi cadunt per quamdam declinationis originem a nominativo, qui dicitur ‘rectus’, eo quod non cadit. Stoici autem dixerunt etiam nominativos dici casus, quos grammatici sequuntur, eo quod cadunt, id est procedunt ab interiori conceptione mentis; et dicitur ‘rectus’, quia nihil prohibet aliquid cadens sic cadere ut rectum stet, sicut stilus qui cadens ligno infigitur.
And he says that “of Cato” and “to Cato” and others of this kind are not names, but the nominative is the one that is said to be a name principally, for the imposition of the name to signify something was made through it. Oblique expressions of the kind cited are called cases of the name because they fall away from the nominative as a kind of source of their declension. On the other hand, the nominative, because it does not fall away, is said to be erect. The Stoics held that even the nominatives were cases (with which the grammarians agree), because they fall, that is, proceed from the interior conception of the mind; and they said they were also called erect because a thing can fall in such a way that it stands erect, as when a pen falls and is fixed in wood.
Peri.L4
50. Ostendit autem consequenter qualiter se habent obliqui casus ad nomen.
Then Aristotle shows how oblique cases are related to the name (16b1).
Peri.L4
Et dicit quod ratio, quam nomen significat, est eadem in aliis, scilicet in casibus nominis, sed in hoc est differentia quod nomen adiunctum cum hoc verbo ‘est’ vel ‘erit’ vel ‘fuit’ semper significat verum vel falsum, quod non contingit in obliquis. Signanter autem inducit exemplum de verbo substantivo, quia sunt quaedam alia verba, scilicet impersonalia, quae cum obliquis significant verum vel falsum, ut cum dicitur: ‘Poenitet Socratem’, quia actus verbi intelligitur ferri super obliquum, ac si diceretur: ‘Poenitentia habet Socratem’.
The definition, as it signifies the name, is the same in the others, namely, in the cases of the name. But they differ in this respect: the name joined to the verb “is” or “will be” or “has been” always signifies the true or false; in oblique cases this is not so. It is significant that the substantive verb is the one he uses as an example, for there are other verbs (namely, impersonal verbs) that do signify the true or false when joined with a name in an oblique case, as in, “It grieves Socrates,” because the act of the verb is understood to be carried over to the oblique cases, as though what were said were, “Grief possesses Socrates.”
Peri.L4
51. Sed, si nomen infinitum et casus non sunt nomina, inconvenienter data est praemissa nominis definitio, quae istis convenit.
However, an objection could be made against Aristotle’s position in this portion of his text. If the infinite name and the cases of the name are not names, then the definition of the name (which belongs to these) is not consistently presented.
Peri.L4
Sed dicendum, secundum Ammonium, quod supra communius definivit nomen, postmodum vero significationem nominis arctat subtrahendo haec a nomine.
We could say, as Ammonius does, that Aristotle defines the name broadly, and afterward limits the signification of the name by subtracting these from it.
Peri.L4
Vel dicendum quod praemissa definitio non simpliciter convenit his: nomen enim infinitum nihil determinatum significat, neque casus nominis significat secundum primum placitum instituentis, ut dictum est.
Or, we could say that the definition Aristotle has given does not belong to these absolutely, since the infinite name signifies nothing determinate, and the cases of the name do not signify according to the first intent of the one instituting the name, as has been said.
Peri.L4
L. 5 (Α.3, 16b6–16b25)On the nature of the verb and its conformity with the nameDe verbi natura et eius convenientia ad nomen
16b6. Verbum autem est quod consignificat tempus, cuius pars nihil extra significat, et est semper eorum quae de altero praedicantur nota.
16b6. The verb is that which signifies with time; no part of it signifies separately, and it is a sign of something said of something else.
Peri.L5
16b8. Dico autem quoniam consignificat tempus, ut ‘cursus’ quidem nomen est, ‘currit’ vero verbum: consignificat enim nunc esse.
16b8. I mean by “signifies with time” that “maturity,” for example, is a name, but “matures” is a verb, for it connotes the present existence of maturity.
Peri.L5
16b10. Et est semper eorum quae de altero dicuntur nota, ut eorum quae de subiecto vel in subiecto.
16b10. Moreover, a verb is always a sign of something that belongs to something, that is, of something belonging to a subject or in a subject.
Peri.L5
16b12. ‘Non currit’ autem et ‘non laborat’ non verbum dico: consignificat quidem tempus et semper de aliquo est. Differentiae autem huic nomen non est positum, sed sit infinitum verbum, quoniam similiter in quolibet est vel quod est vel quod non est.
16b12. “Non-matures” and “non-declines” I do not call verbs. They signify with time and always belong to something, but they differ from the verb and no name has been established for the difference. Let us call them infinite verbs, since they belong equally to anything whatever, to both what is and what is not.
Peri.L5
16b16. Similiter autem ‘curret’ vel ‘currebat’ non verbum est, sed casus verbi. Differt autem a verbo quoniam hoc quidem praesens consignificat tempus, illa vero quod complectitur.
16b16. Likewise, “has matured” and “will mature” are not verbs but modes of the verb. They differ from the verb in that the verb signifies with present time, whereas the modes signify time outside of the present.
Peri.L5
16b19. Ipsa quidem secundum se dicta verba nomina sunt.
16b19. Verbs said by themselves are names.
Peri.L5
16b20. Et significant aliquid. Constituit enim qui dicit intellectum, et qui audit quiescit.
16b20. And they signify something. For in uttering a verb the one speaking informs the mind of the one hearing it and sets it at rest.
Peri.L5
16b21. Sed si est aut non est, nondum significat. Neque enim esse signum est rei vel non esse.
16b21. But they do not yet signify whether a thing is or is not, for the verb is not a sign of the being or non-being of a thing.
Peri.L5
16b23. Nec si hoc ipsum ‘est’ purum dixeris: ipsum quidem nihil est. Consignificat autem quamdam compositionem quam sine compositis non est intelligere.
16b23. Nor would it be a sign of the being or non-being of a thing if you were to say it alone, for it is nothing; it signifies with a composition which cannot be conceived apart from the things composing it.
Peri.L5
52. Verbum autem est quod consignificat tempus et cetera. Postquam Philosophus determinavit de nomine, hic determinat de verbo.
The verb is that which signifies with time. After determining the nature of the name, the Philosopher now determines the nature of the verb.
Peri.L5
Et circa hoc tria facit:
And he does three things:
Peri.L5
primo definit verbum;
first, he defines the verb;
Peri.L5
secundo excludit quaedam a ratione verbi, ibi: ‘Non currit’ autem et ‘non laborat’ et cetera;
second, he excludes certain forms of verbs from the definition, where he says: “non-matures” and “non-declines” (16b12; [61]);
Peri.L5
tertio ostendit convenientiam verbi ad nomen, ibi: Ipsa quidem secundum se dicta et cetera.
third, he shows in what the verb and name agree where he says: verbs in themselves, said alone, are names (16b19; [66]).
Peri.L5
Circa primum duo facit:
About the first he does two things:
Peri.L5
primo ponit definitionem verbi;
first, he defines the verb;
Peri.L5
secundo exponit eam, ibi: Dico autem quoniam consignificat et cetera.
second, he explain the definition where he says: I mean by “signifies with time” (16b8; [58]).
Peri.L5
53. Est autem considerandum quod Aristoteles, brevitati studens, non ponit in definitione verbi ea quae sunt nomini et verbo communia, relinquens ea intellectui legentis, ex his quae dixerat in definitione nominis.
In order to be brief, Aristotle does not give what is common to the name and the verb in the definition of the verb, but leaves this for the reader to understand from the definition of the name.
Peri.L5
Ponit autem tres particulas in definitione verbi.
He posits three elements in the definition of the verb (16b6).
Peri.L5
Quarum prima distinguit verbum a nomine, hoc scilicet quod dicit: quod consignificat tempus: dictum est enim in definitione nominis quod nomen significat sine tempore.
The first of these distinguishes the verb from the name, for the verb signifies with time, the name without time, as was stated in its definition.
Peri.L5
Secunda vero particula est per quam distinguitur verbum ab oratione, scilicet cum dicitur: cuius pars nihil extra significat.
The second element, no part of which signifies separately, distinguishes the verb from speech.
Peri.L5
54. Sed, cum hoc etiam positum sit in definitione nominis, videtur hic debuisse praetermitti, sicut et quod dictum est vox significativa ad placitum.
This second element was also given in the definition of the name; therefore, it seems that this second element, along with vocal sound significant by convention, should have been omitted.
Peri.L5
Ad quod respondet Ammonius quod in definitione nominis hoc positum est ut distinguatur nomen ab orationibus quae componuntur ex nominibus, ut cum dicitur: ‘Homo est animal’; quia vero sunt etiam quaedam orationes quae componuntur ex verbis, ut cum dicitur: ‘Ambulare est moveri’, ut ab his distinguatur verbum, oportuit hoc etiam in definitione verbi iterari.
Ammonius says in reply to this that Aristotle posited this in the definition of the name to distinguish it from speech which is composed of names (as in “man is an animal”), but, since speech may also be composed of verbs (as in “to walk is to move”), this also had to be repeated in the definition of the verb to distinguish it from speech.
Peri.L5
Potest etiam aliter dici <quod>, quia verbum importat compositionem in qua perficitur oratio verum vel falsum significans, maiorem convenientiam videbatur verbum habere cum oratione, quasi quaedam pars formalis ipsius, quam nomen, quod est quaedam pars materialis et subiectiva orationis.
We might also say that since the verb introduces the composition which brings about speech signifying truth or falsity, the verb seems to be more like speech (being a certain formal part of it) than the name, which is a material and subjective part of it. Therefore, this had to be repeated.
Peri.L5
55. Tertia vero particula est per quam distinguitur verbum non solum a nomine, sed etiam a participio, quod significat cum tempore; unde dicit: et est semper eorum quae de altero praedicantur nota, id est signum, quia scilicet nomina et participia possunt poni ex parte subiecti et praedicati, sed verbum semper est ex parte praedicati.
The third element distinguishes the verb not only from the name, but also from the participle, which also signifies with time. He makes this distinction when he says: and it is a sign of something said of something else, that is, names and participles can be posited on the part of the subject and the predicate, but the verb is always posited on the part of the predicate.
Peri.L5
56. Sed hoc videtur habere instantiam in verbis infinitivi modi, quae interdum ponuntur ex parte subiecti, ut cum dicitur: ‘Ambulare est moveri’.
But it seems that verbs are used as subjects. The verb in the infinitive mode is an instance of this, as in the example, “to walk is to be moving.”
Peri.L5
Sed dicendum est quod verba infinitivi modi, quando in subiecto ponuntur, habent vim nominis; unde et in Graeco et in vulgari latina locutione suscipiunt adiectionem articulorum sicut et nomina. Cuius ratio est quia proprium nominis est ut significet rem aliquam quasi per se existentem, proprium autem verbi est ut significet actionem;
Verbs of the infinitive mode, however, have the force of names when they are used as subjects. (Hence in both Greek and ordinary Latin usage articles are added to them as in the case of names.) The reason for this is that it is proper to the name to signify something as existing in itself, but proper to the verb to signify action or passion.
Peri.L5
potest autem actio significari tripliciter:
Now there are three ways of signifying action or passion.
Peri.L5
uno modo per se in abstracto, velut quaedam res, et sic significatur per nomen, ut ‘actio’, ‘passio’, ‘ambulatio’, ‘cursus’, et similia;
It can be signified per se, as a certain thing in the abstract and is thus signified by a name such as “action,” “passion,” “walking,” “running,” and so on.
Peri.L5
alio modo per modum actionis, ut scilicet est egrediens a substantia et inhaerens ei ut subiecto, et sic significatur per verba aliorum modorum, quae attribuuntur personis;
It can also be signified in the mode of an action, that is, as proceeding from a substance and inhering in it as in a subject; in this way action or passion is signified by the verbs of the different modes attributed to predicates.
Peri.L5
sed, quia etiam ipse processus vel inhaerentia actionis potest apprehendi ab intellectu et significari ut res quaedam, inde est quod ipsa verba infinitivi modi, quae significant ipsam inhaerentiam actionis ad subiectum, possunt accipi ut verba, ratione concretionis, et ut nomina, prout significant quasi res quasdam.
Finally—and this is the third way in which action or passion can be signified—the very process or inherence of action can be apprehended by the intellect and signified as a thing. Verbs of the infinitive mode signify such inherence of action in a subject and hence can be taken as verbs by reason of concretion, and as names inasmuch as they signify as things.
Peri.L5
57. Potest etiam obiici de hoc quod etiam verba aliorum modorum videntur aliquando in subiecto poni, ut cum dicitur: ‘Curro est verbum’.
On this point, the objection may also be raised that verbs of other modes sometimes seem to be posited as subjects; for example when we say, “‘Matures’ is a verb.”
Peri.L5
Sed dicendum est quod in tali locutione hoc verbum ‘curro’ non sumitur formaliter, secundum quod eius significatio refertur ad rem, sed secundum quod materialiter significat ipsam vocem, quae accipitur ut res quaedam; et ideo tam verba quam omnes orationis partes, quando ponuntur materialiter, sumuntur in vi nominum.
In such a statement, however, the verb “matures” is not taken formally according as its signification is referred to a thing, but as it signifies the vocal sound itself materially, which vocal sound is taken as a thing. When posited in this way—that is, materially—verbs and all parts of speech are taken with the force of names.
Peri.L5
58. Deinde cum dicit: Dico autem quoniam consignificat tempus et cetera, exponit definitionem positam.
Then, when he says: I mean by “signifies with time” (16b8), he begins to explain the definition of the verb.
Peri.L5
Et primo quantum ad hoc quod dixerat quod consignificat tempus;
First, in regard to this, he says that it signifies with time;
Peri.L5
secundo quantum ad hoc quod dixerat quod est nota eorum quae de altero praedicantur, cum dicit: Et est semper et cetera;
second, that the verb is a sign of something said of something else, at: moreover, a verb is always (16b10; [59]).
Peri.L5
secundam autem particulam, scilicet cuius nulla pars extra significat, non exponit, quia supra exposita est in tractatu nominis.
But he does not explain the second part, no part of which signifies separately, because an explanation of it has already been made in connection with the name.
Peri.L5
Exponit ergo primum quod verbum consignificat tempus, per exemplum, quia videlicet ‘cursus’, quia significat actionem non per modum actionis, sed per modum rei per se existentis, eo quod est nomen, non significat tempus; ‘currit’ vero, cum sit verbum significans actionem, consignificat tempus, quia proprium est motus tempore mensurari, actiones autem nobis notae sunt in tempore; dictum est autem supra quod consignificare tempus est significare aliquid ut tempore mensuratum; unde aliud est significare tempus principaliter ut rem quamdam, quod potest nomini convenire, aliud autem est significare cum tempore, quod non convenit nomini, sed verbo.
First, he shows by an example that the verb signifies with time. “Maturity,” for example, because it signifies action, not in the mode of action but in the mode of a thing existing in itself, does not signify with time, for it is a name. But “matures,” since it is a verb signifying action, signifies with time, because to be measured by time is proper to motion; moreover, actions are known by us in time. We have already mentioned that to signify with time is to signify something measured in time. Hence it is one thing to signify time principally, as a thing, which is appropriate to the name; however, it is another thing to signify with time, which is not proper to the name but to the verb.
Peri.L5
59. Deinde cum dicit: Et est semper et cetera, exponit aliam particulam.
Then, when he says: moreover, a verb is always (16b10), he explains the last part of the definition of the verb.
Peri.L5
Ubi notandum est quod, quia subiectum enuntiationis significatur ut cui inhaeret aliquid, cum verbum significet actionem per modum actionis, de cuius ratione est ut inhaereat, semper ponitur ex parte praedicati, nunquam autem ex parte subiecti, nisi sumatur in vi nominis, ut dictum est.
It should be noted first that the subject of an enunciation signifies as that in which something inheres. Hence, when the verb signifies action through the mode of action (the nature of which is to inhere), it is always posited on the part of the predicate and never on the part of the subject—unless it is taken with the force of a name, as was said.
Peri.L5
Dicitur ergo verbum semper esse nota eorum quae de altero dicuntur, tum quia verbum semper significat id quod praedicatur, tum quia in omni praedicatione oportet esse verbum, eo quod verbum importat compositionem, qua praedicatum componitur subiecto.
The verb, therefore, is always said to be a sign of something that belongs to something, and this not only because the verb always signifies that which is predicated, but also because there must be a verb in every predication, for the verb introduces the composition by which the predicate is united with the subject.
Peri.L5
60. Sed dubium videtur quod subditur: ut eorum quae de subiecto vel in subiecto. Videtur enim aliquid dici ut de subiecto, quod essentialiter praedicatur, ut: ‘Homo est animal’; <ut> in subiecto autem, sicut accidens de subiecto praedicatur, ut: ‘Homo est albus’. Si ergo verba significant actionem vel passionem, quae sunt accidentia, consequens est ut semper significent ea quae dicuntur ut in subiecto; frustra igitur dicitur: de subiecto vel in subiecto.
The last phrase of this portion of the text presents a difficulty, namely, of something belonging to a subject or in a subject. For it seems that something is said of a subject when it is predicated essentially, as in “man is an animal”; but in a subject, when it is an accident that is predicated of a subject, as in “man is white.” But if verbs signify action or passion (which are accidents), it follows that they always signify what is in a subject. It is useless, therefore, to say belonging to a subject or in a subject.
Peri.L5
Et ad hoc respondet Boethius quod utrumque ad idem pertinet: accidens enim et de subiecto praedicatur et in subiecto est. Sed, quia Aristoteles disiunctione utitur, videtur aliud per utrumque significare.
In answer to this, Boethius says that both pertain to the same thing, for an accident is predicated of a subject and is also in a subject. Aristotle, however, uses a disjunction, which seems to indicate that he means something different by each.
Peri.L5
Et ideo potest dici quod, cum Aristoteles dicit quod verbum est semper nota eorum quae de altero praedicantur, non est sic intelligendum quasi significata verborum sunt quae praedicantur, quia, cum praedicatio videatur magis proprie ad vocem pertinere, ipsa verba sunt quae praedicantur magis quam significent praedicata; est igitur intelligendum quod verbum semper est signum quod aliqua praedicentur, quia omnis praedicatio fit per verbum, ratione compositionis importatae, sive praedicetur aliquid essentialiter sive accidentaliter.
Therefore, it could be said in reply to this that when Aristotle says the verb is always a sign of those things that are predicated of another, it is not to be understood as though the things signified by verbs are predicated. For predication seems to pertain more properly to composition; therefore, the verbs themselves are what are predicated and do not signify predicates. The verb, then, is always a sign that something is being predicated, because all predication is made through the verb by reason of the composition introduced, whether what is being predicated is predicated essentially or accidentally.
Peri.L5
61. Deinde cum dicit: ‘Non currit’ autem et cetera, excludit quaedam a ratione verbi.
Then, when he says: “non-matures” and “non-declines” (16b12), he excludes certain forms of verbs from the definition of the verb.
Peri.L5
Et primo verbum infinitum;
First, he excludes the infinite verb;
Peri.L5
secundo verba praeteriti temporis vel futuri, ibi: Similiter autem ‘curret’ vel ‘currebat’ et cetera.
second, the verbs of past and future time, at: likewise, “has matured” and “will mature” (16b16; [63]).
Peri.L5
Dicit ergo primo quod ‘non currit’ et ‘non laborat’ non proprie dicitur verbum: est enim proprium verbi significare aliquid per modum actionis vel passionis, quod praedictae dictiones non faciunt; removent enim actionem vel passionem potius quam aliquam actionem vel passionem determinatam significent. Sed, quamvis non proprie possit dici verbum, tamen conveniunt sibi ea quae supra posita sunt in definitione verbi.
Therefore, he says first that “non-matures” and “non-declines” cannot strictly speaking be called verbs for it is proper to the verb to signify something in the mode of action or passion. But these words remove action or passion rather than signify a determinate action or passion. Now, while they cannot properly be called verbs, all the parts of the definition of the verb apply to them.
Peri.L5
Quorum primum est quod consignificat tempus, quia significat agere et pati, quae sicut sunt in tempore, ita et privatio horum: unde et quies tempore mensuratur, ut habetur in IV Physicorum.
First of all, the verb signifies time, because it signifies to act or to be acted upon. Since these are in time, so are their privations (and thus rest, too, is measured by time, as is said in Physics).1
Peri.L5
Secundum est quod semper ponitur ex parte praedicati, sicut et verbum, et hoc ideo quia negatio reducitur ad genus affirmationis, unde, sicut verbum quod significat actionem vel passionem significat aliquid ut in altero existens, ita praedictae dictiones significant remotionem actionis vel passionis
Again, the infinite verb is always posited on the part of the predicate, just as the verb is. The reason is that negation is reduced to the genus of affirmation. Hence, just as the verb, which signifies action or passion, signifies something as existing in another, so the foresaid words signify the remotion of action or passion.
Peri.L5
62. (si quis autem obiiciat: si praedictis dictionibus convenit definitio verbi, ergo sunt verba,
Now, someone might object that if the definition of the verb applies to the above words, then they are verbs.
Peri.L5
dicendum est quod definitio verbi supra posita datur de verbo communiter sumpto, huiusmodi autem negantur esse verba quia deficiunt a perfecta ratione verbi).
In answer to this, it should be pointed out that the definition which has been given of the verb is the definition of it taken commonly. Insofar as these words fall short of the perfect notion of the verb, they are not called verbs.
Peri.L5
Nec tamen ante Aristotelem erat nomen positum huic generi dictionum a verbis differentium; sed, quia huiusmodi dictiones in aliquo cum verbis conveniunt, deficiunt tamen a determinata significatione verbi, vocat ea verba infinita. Et rationem nominis assignat, quia unumquodque eorum indifferenter potest dici de eo quod est vel de eo quod non est: sumitur enim negatio apposita non in vi privationis, sed in vi simplicis negationis; privatio enim ponit determinatum subiectum. Differunt tamen huiusmodi verba a verbis negativis, quia verba infinita sumuntur in vi unius dictionis, verba vero negativa in vi duarum dictionum.
Before Aristotle’s time, a name had not been established for a word that differs from verbs as these do. He calls them infinite verbs because such words agree in some things with verbs and yet fall short of the determinate notion of the verb. The reason for the name, he says, is that an infinite verb can be said indifferently of what is or what is not, for the adjoined negation is taken not with the force of privation, but with the force of simple negation, since privation supposes a determinate subject. Infinite verbs do differ from negative verbs, however, for infinite verbs are taken with the force of one word, negative verbs with the force of two.
Peri.L5
63. Deinde cum dicit: Similiter autem ‘curret‘ et cetera, excludit a verbo verba praeteriti temporis et futuri.
Then when he says: likewise, “has matured” (16b16), he excludes verbs of past and future time from the definition.
Peri.L5
Et dicit quod, sicut verba infinita non sunt simpliciter verba, ita etiam ‘curret’, quod est futuri temporis, vel ‘currebat’, quod est praeteriti temporis, non est verbum, sed sunt casus verbi; et differunt in hoc a verbo, quod verbum consignificat praesens tempus, illa vero significant tempus hinc et inde circumstans.
And he says that just as infinite verbs are not verbs absolutely, so “will mature”, which is of future time, or “has matured”, of past time, are not verbs, but they are cases of the verb, and differ from the verb (which signifies with present time) by signifying time before and after the present.
Peri.L5
Dicit autem signanter praesens tempus et non simpliciter praesens, ne intelligatur praesens indivisibile, quod est instans, quia in instanti non est motus nec actio aut passio; sed oportet accipere praesens tempus quod mensurat actionem quae incepit et nondum est terminata per actum.
Aristotle expressly says present time and not just present because he does not mean here the indivisible present which is the instant, for in the instant there is neither movement, nor action, nor passion. Present time is to be taken as the time that measures action which has begun and has not yet been terminated in act.
Peri.L5
Recte autem ea quae consignificant praeteritum tempus et futurum non sunt verba proprie dicta: cum enim verbum proprie sit quod significat agere vel pati, hoc proprie verbum est quod significat agere vel pati in actu, quod est agere vel pati simpliciter; sed agere vel pati in praeterito vel futuro est secundum quid.
Accordingly, verbs that signify with past or future time are not verbs in the proper sense of the term, for the verb is that which signifies to act or to be acted upon; therefore, strictly speaking, it signifies to act or to be acted upon in act, which is to act or to be acted upon simply. But to act or to be acted upon in past or future time is relative.
Peri.L5
64. Dicuntur etiam verba praeteriti temporis vel futuri rationabiliter casus verbi quod significat praesens tempus, quia praeteritum vel futurum dicitur per respectum ad praesens: est enim praeteritum quod fuit praesens, futurum autem quod erit praesens.
It is with reason that verbs of past or future time are called cases of the verb signifying with present time, for past or future are said with respect to the present, the past being that which was present, the future, that which will be present.
Peri.L5
65. Cum autem declinatio verbi varietur per modos, tempora, numeros et personas, variatio quae fit secundum numerum et personam non constituit casus verbi, quia talis variatio non est ex parte actionis, sed ex parte subiecti; sed variatio quae est secundum modos et tempora respicit ipsam actionem, et ideo utraque constituit casus verbi: nam verba imperativi vel optativi modi casus dicuntur sicut et verba praeteriti temporis vel futuri; sed verba indicativi modi praesentis temporis non dicuntur casus, cuiuscumque sint personae vel numeri.
Although the inflection of the verb is varied by mode, time, number, and person, the variations that are made in number and person do not constitute cases of the verb, since such variation is on the part of the subject, not on the part of the action. But variation in mode and time refers to the action itself and hence both of these constitute cases of the verb. For verbs of the imperative or optative modes are called cases, as well as verbs of past or future time. Verbs of the indicative mode in present time, however, are not called cases, regardless of their person and number.
Peri.L5
66. Deinde cum dicit: Ipsa quidem secundum se dicta et cetera, ostendit convenientiam verborum ad nomina.
Then, when he says: verbs in themselves, said alone, are names (16b19), he points out the conformity between verbs and names.
Peri.L5
Et circa hoc duo facit:
And concerning this he does two things:
Peri.L5
primo proponit quod intendit;
first, he proposes what he intends to do;
Peri.L5
secundo manifestat propositum, ibi: Et significant aliquid et cetera.
second, he manifests it, at: and they signify something (16b20; [67]).
Peri.L5
Dicit ergo primo quod ipsa verba secundum se dicta sunt nomina.
First, then, he says that verbs said by themselves are names (16b19).
Peri.L5
Quod a quibusdam exponitur de verbis quae sumuntur in vi nominis, ut dictum est, sive sint infinitivi modi, ut cum dicitur: ‘Currere est moveri’, sive sint alterius modi, ut cum dico: ‘Curro est verbum’. Sed haec non videtur intentio Aristotelis, quia ad hanc intentionem non respondent sequentia.
Some have taken this to mean those verbs that are taken with the force of names—either verbs of the infinitive mode (as in “to run is to be moving”), or verbs of another mode (as in “‘matures’ is a verb”). But this does not seem to be what Aristotle means, for it does not correspond to what he says next.
Peri.L5
Et ideo aliter dicendum est quod nomen hic sumitur prout communiter significat quamlibet dictionem impositam ad significandum aliquam rem; et, quia etiam agere vel pati est quaedam res, inde est quod ipsa verba in quantum nominant, id est significant, agere et pati, sub nominibus comprehenduntur communiter acceptis. Nomen autem, prout a verbo distinguitur, significat rem sub determinato modo, prout scilicet potest intelligi ut in se existens; unde nomina possunt subiici et praedicari.
Therefore, name must be taken in another way here, that is, as it commonly signifies any word whatever that is imposed to signify a thing. Now, since to act or to be acted upon is also a certain thing, verbs themselves as they name, that is, as they signify to act or to be acted upon, are comprehended under names taken commonly. The name as distinguished from the verb signifies the thing under a determinate mode, that is, according as the thing can be understood as existing in itself. This is the reason names can be subjected and predicated.
Peri.L5
67. Deinde cum dicit: Et significant aliquid et cetera, probat propositum.
He proves the point he has just made when he says: and they signify something (16b20).
Peri.L5
Et primo per hoc quod verba significant aliquid sicut et nomina;
First, by showing that verbs, like names, signify something;
Peri.L5
secundo <per hoc> quod non significant verum vel falsum, sicut nec nomina, ibi: Sed si est aut non est et cetera.
second, by showing that, like names, they do not signify truth or falsity when he says: but they do not yet signify (16b21; [69]).
Peri.L5
Dicit ergo primo quod in tantum dictum est quod verba sunt nomina in quantum significant aliquid. Et hoc probat, quia supra dictum est quod voces significativae significant intellectus, unde proprium vocis significativae est quod generet aliquem intellectum in animo audientis; et ideo, ad ostendendum quod verbum sit vox significativa, assumit quod ille qui dicit verbum constituit intellectum in animo audientis, et ad hoc manifestandum inducit quod ille qui audit quiescit.
He says first that verbs have been said to be names only insofar as they signify a thing (16b20). He proves this by saying it has already been said that significant vocal sound signifies thought; hence it is proper to significant vocal sound to produce something understood in the mind of the one who hears it. To show, then, that a verb is significant vocal sound, he assumes that the one who utters a verb brings about understanding in the mind of the one who hears it. The evidence he introduces for this is that the mind of the one who hears it is set at rest.
Peri.L5
68. Sed hoc videtur esse falsum, quia sola oratio perfecta facit quiescere intellectum, non autem neque nomen neque verbum si per se dicatur: si enim dicam ‘homo’, suspensus est animus audientis quid de eo dicere velim; si autem dicam ‘currit’, suspensus est animus eius de quo dicam.
But what Aristotle says here seems to be false, for it is only perfect speech that makes the intellect rest. The name or the verb, if said by themselves, do not do this. For example, if I say “man,” the mind of the hearer is left in suspense as to what I wish to say about him; and if I say “runs,” the hearer’s mind is left in suspense as to whom I am speaking of.
Peri.L5
Sed dicendum est quod duplex est operatio intellectus, ut supra habitum est; ille qui dicit nomen vel verbum secundum se, constituit intellectum quantum ad primam operationem, quae est conceptio alicuius, et secundum hoc quiescit animus audientis, qui suspensus erat ante quam nomen vel verbum proferretur et eius prolatio terminaretur; non autem constituit intellectum quantum ad secundam operationem, quae est intellectus componentis et dividentis, verbum vel nomen secundum se dictum, nec quantum ad hoc quiescere facit audientem.
It should be said in answer to this objection that the operation of the intellect is twofold, as was said above, and therefore the one who utters a name or a verb by itself determines the intellect with respect to the first operation, which is the simple conception of something. It is in relation to this that the one hearing, whose mind was undetermined before the name or the verb was being uttered and its utterance terminated, is set at rest. Neither the name nor the verb said by itself, however, determines the intellect in respect to the second operation, which is the operation of the intellect composing and dividing; nor do the verb or the name said alone set the hearer’s mind at rest in respect to this operation.
Peri.L5
69. Et ideo statim subdit: Sed si est aut non est, nondum significat, id est nondum significat aliquid per modum compositionis aut divisionis, aut veri vel falsi. Et hoc est quod probare intendit.
Aristotle therefore immediately adds: but they do not yet signify whether a thing is or is not (16b21), that is, they do not yet signify something by way of composition and division, or by way of truth or falsity.
Peri.L5
Probat autem consequenter per illa verba quae maxime videntur significare veritatem vel falsitatem, scilicet ipsum verbum quod est ‘esse’ et verbum infinitum quod est ‘non esse’, quorum neutrum per se dictum est signum veritatis vel falsitatis in re; unde multo minus alia.
This is the second thing he intends to prove, and he proves it by the verbs that especially seem to signify truth or falsity, namely, the verb “to be” and the infinite verb “to non-be,” neither of which, said by itself, signifies real truth or falsity (and much less so do any other verbs).
Peri.L5
Vel potest intelligi hoc generaliter dici de omnibus verbis: quia enim dixerat quod verbum non significat si est res vel non est, hoc consequenter manifestat, quia nullum verbum est signum esse rei vel non esse, id est quod res sit vel non sit; quamvis enim omne verbum finitum implicet esse, quia ‘currere’ est ‘currentem esse’, et omne verbum infinitum implicet non esse, quia ‘non currere’ est ‘non currentem esse’, tamen nullum verbum significat hoc totum, rem esse vel non esse.
This could also be understood in a more general way—that is, that here he is speaking of all verbs—for he says that the verb does not signify whether a thing is or is not. He manifests this further, therefore, by saying that no verb is a sign of a thing’s being or non-being, that is, that a thing is or is not. For although every finite verb implies being, for “to run” is “to be running,” and every infinite verb implies non-being, for “to non-run” is “to be non-running,” nevertheless, no verb signifies the whole, namely, that a thing is or a thing is not.
Peri.L5
70. Et hoc consequenter probat per id de quo magis videtur, cum subdit: Nec si hoc ipsum ‘est’ purum dixeris: ipsum quidem nihil est.
He proves this point from something in which it will be clearer when he adds: nor would it be a sign of the being or non-being of a thing if you were to say “is” alone, for it is nothing (16b23).
Peri.L5
Ubi notandum est quod in Graeco habetur: Neque si ens ipsum nudum dixeris, ipsum quidem nihil est.
It should be noted that the Greek text has the word “being” in place of “is” here.
Peri.L5
Ad probandum vero quod verba non significant rem esse vel non esse, assumpsit id quod est fons et origo <omnium verborum, scilicet> ipsum ens, de quo dicit quod nihil est,
In order to prove that verbs do not signify that a thing is or is not, he takes the source and origin of all words—namely, being itself—of which he says that it is nothing.
Peri.L5
ut Alexander exponit, quia ens aequivoce dicitur de decem praedicamentis, omne autem aequivocum per se positum nihil designat, nisi aliquid addatur quod determinet eius significationem; unde nec ipsum <ens> per se dictum significat quod est vel non est.
Alexander explains this passage in the following way. Aristotle says being itself is nothing because being is said equivocally of the ten predicaments, and, since an equivocal name used by itself signifies nothing unless something is added to determine its signification, thus “is” said by itself does not signify what is or is not.
Peri.L5
Sed haec expositio non videtur conveniens,
But this explanation is not appropriate for this text.
Peri.L5
tum quia ens non dicitur pure aequivoce, sed secundum prius et posterius, unde simpliciter dictum intelligitur de eo quod per prius dicitur,
In the first place, “being” is not, strictly speaking, said equivocally, but according to the prior and posterior. Consequently, when said absolutely, it is understood of that of which it is said primarily.
Peri.L5
tum etiam quia dictio aequivoca non ‘nihil’ significat, sed multa significat, et quandoque hoc et quandoque illud per ipsam accipitur,
Second, an equivocal word does not signify nothing, but many things, sometimes being taken for one, sometimes for another.
Peri.L5
tum etiam quia talis expositio non multum facit ad intentionem praesentem.
Third, such an explanation does not have much application here.
Peri.L5
Unde Porphyrius aliter exposuit quod hoc ipsum ‘ens’ non significat naturam alicuius rei, sicut hoc nomen ‘homo’ vel ‘sapiens’, sed solum designat quamdam coniunctionem; unde subdit quod consignificat quamdam compositionem quam sine compositis non est intelligere.
Porphyry explains this passage in another way. He says that “being” itself does not signify the nature of a thing as the names “man” or “wise” do, but only designates a certain conjunction. This is why Aristotle adds: it signifies with a composition, which cannot be conceived apart from the things composing it (16b23).
Peri.L5
Sed nec hoc videtur convenienter dici, quia, si non significaret aliquam rem, sed solum coniunctionem, non esset neque nomen neque verbum, sicut nec praepositiones aut coniunctiones.
This explanation does not seem to be consistent with the text either, for if “being” itself does not signify a thing, but only a conjunction, it, like prepositions and conjunctions, is neither a name nor a verb.
Peri.L5
71. Et ideo aliter exponendum est, sicut Ammonius exponit, quod ipsum ‘ens’ nihil est, id est non significat verum vel falsum; et rationem huius assignat cum subdit: Consignificat autem quamdam compositionem; nec accipitur hic, ut ipse dicit, ‘consignificat’, sicut cum dicebatur quod verbum consignificat tempus, sed ‘consignificat’, id est ‘cum alio significat’, scilicet alii adiunctum compositionem significat, quae non potest intelligi sine extremis compositionis.
Therefore, Ammonius thought this should be explained in another way. He says “being” itself is nothing means that it does not signify truth or falsity. And the reason for this is given when Aristotle says, it signifies with a composition. The “signifies with,” according to Ammonius, does not mean what it does when it is said that the verb “signifies with time”; “signifies with” here means “signifies with something,” that is, joined to another it signifies composition, which cannot be understood without the extremes of the composition.
Peri.L5
Sed quia <hoc> commune est omnibus nominibus et verbis, non videtur haec expositio esse secundum intentionem Aristotelis, qui assumpsit unum ‘ens’ quasi quiddam speciale.
But since it is common to all names and verbs not to signify truth or falsity, this explanation does not seem to be in accordance with the intention of Aristotle, who takes “being” here as though it were something special.
Peri.L5
Et ideo, ut magis sequamur verba Aristotelis, considerandum est quod ipse dixerat quod verbum non significat rem esse vel non esse; addit autem quod non solum verbum non significat rem esse vel non esse, sed nec hoc ipsum ‘ens’ significat rem esse vel non esse, et hoc est quod dicit: nihil est, id est non significat aliquid esse. Et tamen maxime videbatur de hoc quod dico ‘ens’, quia ‘ens’ nihil aliud est quam ‘quod est’, et sic videtur <et> rem significare, per hoc quod dico <’quod’, et esse, per hoc quod dico> ‘est’. Et si quidem haec dictio ‘ens’ significaret esse principaliter sicut significat rem quae habet esse, procul dubio significaret aliquid esse; sed ipsam compositionem, quae importatur in hoc quod dico ‘est’, non principaliter significat, sed consignificat eam in quantum significat rem habentem esse; unde talis consignificatio compositionis non sufficit ad veritatem vel falsitatem, quia compositio in qua consistit veritas et falsitas non potest intelligi nisi secundum quod innectit extrema compositionis.
Therefore, in order to understand what Aristotle is saying, we should note that he has just said that the verb does not signify whether a thing exists or does not exist. Nor does “being” signify that a thing exists or does not exist. This is what he means when he says: it is nothing, that is, it does not signify that a thing exists. This is indeed most clearly seen in saying “being,” because “being” is nothing other than that which is. And thus we see that it signifies both a thing, when I say “that which,” and existence, when I say “is.” If the word “being” as signifying a thing having existence were to signify existence principally, without a doubt it would signify that a thing exists. But the word “being” does not principally signify the composition that is implied in saying “is”; rather, it signifies with composition inasmuch as it signifies the thing having existence. Such signifying with composition is not sufficient for truth or falsity, for the composition in which truth and falsity consists cannot be understood unless it connects the extremes of a composition.
Peri.L5
72. Si vero dicatur: nec ipsum ‘est’, ut libri nostri habent, planior est sensus: quod enim nullum verbum significet rem esse vel non esse, probat per hoc verbum ‘est’, quod secundum se dictum non significat aliquid esse, licet significet esse. Et, quia hoc ipsum ‘esse’ videtur compositio quaedam, et ita hoc verbum ‘est’, quod significat esse, potest videri significare compositionem in qua sit verum vel falsum,
If in place of what Aristotle says, we say nor would “to be” itself, as it is in our texts, the meaning is clearer. For Aristotle proves through the verb “is” that no verb signifies that a thing exists or does not exist, since “is” said by itself does not signify that a thing exists, although it signifies existence. And because to be itself seems to be a kind of composition, so also the verb “is,” which signifies to be, can seem to signify the composition in which there is truth or falsity.
Peri.L5
ad hoc excludendum subdit quod ista compositio, quam significat hoc verbum ‘est’, non potest intelligi sine componentibus, quia dependet eius intellectus ex extremis, quae si non apponantur, non est perfectus intellectus compositionis, ut possit in ea esse verum vel falsum.
To exclude this, Aristotle adds that the composition which the verb “is” signifies cannot be understood without the composing things. The reason for this is that an understanding of the composition which “is” signifies depends on the extremes, and unless they are added, understanding of the composition is not complete and hence cannot be true or false.
Peri.L5
73. Ideo autem dicit quod hoc verbum ‘est’ consignificat compositionem, quia non principaliter eam significat, sed ex consequenti: significat enim id quod primo cadit in intellectu per modum actualitatis absolute; nam ‘est’ simpliciter dictum significat esse actu, et ideo significat per modum verbi. Quia vero actualitas, quam principaliter significat hoc verbum ‘est’, est communiter actualitas omnis formae vel actus, substantialis vel accidentalis, inde est quod, cum volumus significare quamcumque formam vel actum actualiter inesse alicui subiecto, significamus illud per hoc verbum ‘est’, simpliciter quidem secundum praesens tempus, secundum quid autem secundum alia tempora; et ideo ex consequenti hoc verbum ‘est’ significat compositionem.
Therefore, he says that the verb “is” signifies with composition, for it does not signify composition principally but consequently. It primarily signifies that which is perceived in the mode of actuality absolutely, for “is,” said simply, signifies to be in act, and therefore signifies in the mode of a verb. However, the actuality which the verb “is” principally signifies is the actuality of every form commonly, whether substantial or accidental. Hence, when we wish to signify that any form or act is actually in some subject, we signify it through the verb “is,” either absolutely or relatively—absolutely, according to present time; relatively, according to other times. For this reason the verb “is” signifies composition, not principally, but consequently.
Peri.L5
L. 6 (Α.4, 16b26–17a2)On speech, the formal principle of the enunciationDe principio formali enunciationis, quod est oratio
16b26. Oratio est vox significativa, cuius partium aliquid significativum est separatum, ut dictio, non ut affirmatio.
16b26. Speech is significant vocal sound, some parts of which are significant separately, that is, as words but not as an affirmation.
Peri.L6
16b28. Dico autem ut ‘homo’ significat aliquid, sed non quoniam est aut non est. Sed erit affirmatio vel negatio, si quid addatur.
16b28. Let me explain. The word “man” signifies something, but it does not signify that it is or that it is not; it will be an affirmation or negation, however, if something is added.
Peri.L6
16b30. Sed non una nominis syllaba. Nec in hoc quidem quod est ‘sorex’, ‘rex’ significat, sed vox est nunc sola. In duplicibus vero significat quidem, sed non secundum se, sed quemadmodum dictum est.
16b30. But one syllable of a name does not signify anything; similarly, in the word “fowl,” “owl” does not signify anything in itself, but is only a vocal sound. In composite names, however, the part does signify something, but not in itself, as has been said.
Peri.L6
17a1. Est autem oratio omnis quidem significativa non sicut instrumentum, sed, quemadmodum dictum est, secundum placitum.
17a1. But all speech1 is significant—not just as an instrument, however, but by convention, as has been said.
Peri.L6
74. Oratio est vox significativa et cetera. Postquam Philosophus determinavit de nomine et verbo, quae sunt principia materialia enuntiationis utpote partes eius existentes, nunc determinat de oratione, quae est principium formale enuntiationis utpote genus eius existens.
Speech is significant vocal sound. Having established and explained the definition of the name and the verb, which are the material principles of the enunciation inasmuch as they are its parts, the Philosopher now determines and explains what speech is, which is the formal principle of the enunciation inasmuch as it is its genus.
Peri.L6
Et circa hoc tria facit:
About this, he does three things:
Peri.L6
primo proponit definitionem orationis;
first, he proposes the definition of speech;
Peri.L6
secundo exponit eam, ibi: Dico autem ut ‘homo’ et cetera;
second, he explains it, at: let me explain (16b28; [78]);
Peri.L6
tertio excludit errorem, ibi: Est autem oratio omnis et cetera.
third, he excludes an error where he says: but all speech is significant (17a1; [80]).
Peri.L6
75. Circa primum considerandum est quod Philosophus in definitione orationis primo ponit id in quo oratio convenit cum nomine et verbo, cum dicit: Oratio est vox significativa; quod etiam posuit in definitione nominis, et probavit de verbo quod aliquid significet, non autem posuit in eius definitione, quia supponebat ex eo quod positum erat in definitione nominis, studens brevitati, ne idem frequenter iteraret; iterat tamen hoc in definitione orationis, quia significatio orationis differt a significatione nominis vel verbi, quia nomen vel verbum significat simplicem intellectum, oratio autem significat intellectum compositum.
In defining speech, the Philosopher first states what it has in common with the name and verb where he says: speech is significant vocal sound (16b26). This was posited in the definition of the name but not repeated in the case of the verb, because it was supposed from the definition of the name. This was done for the sake of brevity and to avoid repetition; but subsequently he did prove that the verb signifies something. He repeats this, however, in the definition of speech because the signification of speech differs from that of the name and the verb, for the name and the verb signify simple thought, whereas speech signifies composite thought.
Peri.L6
76. Secundo autem ponit id in quo oratio differt a nomine et verbo, cum dicit: cuius partium aliquid significativum est separatum. Supra enim dictum est quod pars nominis non significat aliquid per se separata, sed solum quod est coniunctum ex duabus partibus. Signanter autem non dicit: cuius pars est significativa aliquid separata, sed: cuius aliquid partium est significativum, propter negationes et alia syncategoremata, quae secundum se non significant aliquid absolutum, sed solum habitudinem unius ad alterum.
Second, he posits what differentiates speech from the name and verb when he says: some parts of which are significant separately. For a part of a name taken separately does not signify anything in itself, except in the case of a name composed of two parts, as he said above. Note that he says: some parts of which are significant, and not, a part of which is significant separately; this is to exclude negations and the other words used to unite categorical words, which do not in themselves signify something absolutely, but only the relationship of one thing to another.
Peri.L6
Sed, quia duplex est significatio vocis, una quae refertur ad intellectum compositum, alia autem quae refertur ad intellectum simplicem, prima significatio competit orationi, secunda vero competit parti orationis, unde subdit: ut dictio, non ut affirmatio. Quasi dicat: pars orationis significativa est sicut dictio, puta significat <ut> nomen et verbum, non sicut affirmatio quae componitur ex nomine et verbo. Facit autem mentionem solum de affirmatione, non autem de negatione, quia negatio secundum vocem superaddit aliquid affirmationi, unde, si pars orationis propter sui simplicitatem non significat aliquid ut affirmatio, multo minus significat aliquid ut negatio.
Then, because the signification of vocal sound is twofold, one being referred to composite thought, the other to simple thought (the first belonging to speech, the second, not to speech but to a part of speech), he adds: as words but not as an affirmation. What he means is that a part of speech signifies in the way a word—say, a name or a verb—signifies; it does not signify in the way an affirmation signifies, which is composed of a name and a verb. He only mentions affirmation because negation adds something to affirmation as far as vocal sound is concerned, for if a part of speech does not signify as an affirmation since it is simple, it will not signify as a negation.
Peri.L6
77. Sed contra hanc definitionem Aspasius obiicit, quia videtur non omnibus partibus orationis convenire: sunt enim quaedam orationes compositae quarum partes significant aliquid ut affirmatio, puta: Si sol lucet super terram, dies est.
Aspasius objects to this definition because it does not seem to belong to all parts of speech. For there is a kind of speech, he says, in which some of the parts signify as an affirmation, such as, “If the sun shines over the earth, it is day.”
Peri.L6
Et ad hoc respondet Alexander quod in quocumque genere invenitur prius et posterius, debet definiri id quod prius est, sicut cum definitio datur alicuius speciei, puta hominis, intelligitur definitio de eo quod est in actu, non de eo quod est in potentia; et ideo, quia in genere orationis primum est oratio simplex, inde est quod Aristoteles definit orationem simplicem.
Porphyry says in reply to this objection that in whatever genus there is something prior and posterior, it is the prior thing that has to be defined. For example, when we give the definition of a species—say, of man—the definition is understood of that which is in act, not of that which is in potency. Since, then, in the genus of speech, simple speech is prior, Aristotle defines it first.
Peri.L6
Vel potest dici, secundum Alexandrum et Ammonium, quod hic definitur oratio in communi; unde debet poni in definitione hac illud quod commune est orationi simplici et compositae; habere autem partes significantes per modum affirmationis competit soli orationi compositae, sed habere partes quae significant per modum dictionis et non per modum affirmationis est commune orationi simplici et compositae; et ideo hoc debuit poni in definitione orationis. Et secundum hoc non debet intelligi esse de ratione orationis quod pars eius non sit affirmatio, sed quasi <de> ratione orationis est quod pars eius sit aliquid quod significat per modum dictionis et non per modum orationis.
Or, we can answer the objection in the way Alexander and Ammonius do. They say that speech is defined here commonly. Hence what is common to simple and composite speech ought to be stated in the definition. Now, to have parts signifying something as an affirmation belongs only to composite speech, but to have parts signifying something in the mode of a word and not in the mode of an affirmation is common to simple and composite speech. Therefore, this had to be posited in the definition of speech. We should not conclude, however, that it is of the nature of speech that its part not be an affirmation, but rather that it is of the nature of speech that its parts be something that signify in the manner of words, and not in the manner of an affirmation.
Peri.L6
Et in idem redit solutio Porphyrii quantum ad sensum, licet quantum ad verba parumper differat. Quia enim frequenter Aristoteles ponit ‘dicere’ pro ‘affirmare’, ne ‘dictio’ pro ‘affirmatione’ sumatur, dicto quod pars orationis significat ut dictio, addit: non ut affirmatio, quasi dicat, secundum sensum Porphyrii: non accipiatur nunc dictio secundum quod idem quod affirmatio.
Porphyry’s solution reduces to the same thing as far as meaning is concerned, although it is a little different verbally. Aristotle frequently uses “to say” for “to affirm,” and hence to prevent “word” from being taken as “affirmation” when he says that a part of speech signifies as a word, he immediately adds, not as an affirmation, meaning—according to Porphyry’s view—“word” is not taken here in the sense in which it is the same as “affirmation.”
Peri.L6
Philosonus autem, qui dicitur Ioannes Grammaticus, voluit quod haec definitio orationis solum daretur de oratione perfecta, eo quod partes non videntur esse nisi alicuius perfecti, sicut omnes partes domus referuntur ad domum; et ita, secundum ipsum, sola oratio perfecta habet partes significativas.
A philosopher called John the Grammarian thought that this definition could only apply to perfect speech because there only seem to be parts in the case of something perfect, or complete (such as a house to which all of the parts are referred). Therefore, only perfect speech has significant parts.
Peri.L6
Sed in hoc decipiebatur, quia, quamvis omnes partes referantur principaliter ad totum perfectum, quaedam tamen partes referuntur ad ipsum immediate, sicut paries et tectum ad domum, et membra organica ad animal, quaedam vero mediantibus partibus principalibus quarum sunt partes, sicut lapides referuntur ad domum mediante pariete, nervi et ossa ad animal mediantibus membris organicis, scilicet manu et pede et huiusmodi. Sic igitur omnes partes orationis referuntur principaliter ad orationem perfectam, cuius pars est etiam oratio imperfecta, quae et ipsa habet partes significantes. Unde ista definitio convenit tam orationi perfectae quam imperfectae.
He was in error on this point, however, for while it is true that all the parts are referred principally to the perfect, or complete whole, some parts are referred to it immediately—for example, the walls and roof to a house and organic members to an animal. Others, however, are referred to it through the principal parts of which they are parts—for example, stones to the house by the mediate wall, and nerves and bones to the animal by the mediate organic members like the hand and the foot and such things. In the case of speech, therefore, all of the parts are principally referred to perfect speech, a part of which is imperfect speech, which also has significant parts. Hence this definition belongs both to perfect and to imperfect speech.
Peri.L6
78. Deinde cum dicit: Dico autem ut ‘homo’ et cetera, exponit propositam definitionem.
When he says: let me explain (16b28), he elucidates the definition.
Peri.L6
Et primo manifestat verum esse quod dicitur;
First, he shows that what he says is true;
Peri.L6
secundo excludit falsum intellectum, ibi: Sed non una nominis syllaba et cetera.
second, he excludes a false understanding of it where he says: but one syllable of a name does not signify anything (16b30; [79]).
Peri.L6
Exponit ergo primo quod dixerat, aliquid partium orationis esse significativum, sicut hoc nomen ‘homo’, quod est pars orationis, significat aliquid, sed non ut affirmatio aut negatio, quia non significat esse vel non esse, et hoc dico in actu, sed solum in potentia: potest enim aliquid addi per cuius additionem fiet affirmatio vel negatio, scilicet si addatur ei verbum.
He explains that when he says some parts of speech are significant, he means that some of the parts signify something in the way the name “man,” which is a part of speech, signifies something, and yet does not signify as an affirmation or negation, because it does not signify to be or not to be. By this I mean it does not signify affirmation or negation in act, but only in potency, for it is possible to add something that will make it an affirmation or negation, that is, if there is added to it a verb.
Peri.L6
79. Deinde cum dicit: Sed non una nominis syllaba et cetera, excludit falsum intellectum.
Then he excludes a false understanding when he says: but one syllable of a name does not signify anything (16b30).
Peri.L6
Et posset hoc referri ad immediate dictum, ut sit sensus quod nomen erit affirmatio vel negatio si quid ei addatur, sed non si addatur ei una nominis syllaba.
This could be referred to what has just been said, and the meaning would be that the name will be an affirmation or negation if something is added to it, but not if what is added is one syllable of a name.
Peri.L6
Sed, quia huic sensui non congruunt verba sequentia, oportet quod referatur ad id quod supra dictum est, scilicet in definitione orationis, scilicet quod aliquid partium eius est significativum separatum. Sed, quia pars alicuius totius dicitur proprie illud quod immediate venit ad constitutionem totius, non autem pars partis, ideo hoc intelligendum est de partibus ex quibus immediate constituitur oratio, scilicet de nomine et verbo, non autem de partibus nominis vel verbi, quae sunt syllabae vel litterae. Et ideo dicit quod pars orationis est significativa separatim, non tamen talis pars quae est una nominis syllaba.
However, what he says next is not compatible with this meaning; therefore, these words should be referred to what was stated earlier in defining speech, namely, to some parts of which are significant separately. Now, since what is properly called a part of a whole is that which contributes immediately to the formation of the whole, and not that which is a part of a part, “some parts” should be understood as the parts from which speech is immediately formed—that is, the name and verb—and not as parts of the name or verb, which are syllables or letters. Hence, what is being said here is that a part of speech is significant separately but not such a part as one syllable of a name.
Peri.L6
Et hoc manifestat in syllabis, quae quandoque possunt esse dictiones per se significantes, sicut hoc quod dico ‘rex’ quandoque est quaedam dictio per se significans, in quantum vero accipitur ut syllaba quaedam huius nominis ‘sorex, soricis’, non significat aliquid per se, sed est vox sola; dictio enim est quidem vox composita ex pluribus vocibus, tamen in significando habet simplicitatem, in quantum scilicet significat simplicem intellectum; et ideo, in quantum est vox composita, potest habere partem quae sit vox; in quantum autem est simplex in significando, non potest habere partem significantem. Unde syllabae sunt quidem voces, sed non voces per se significantes.
He manifests this by means of syllables that sometimes can be words signifying in itself. “Owl,” for example, is sometimes one word signifying in itself. When taken as a syllable of the name “fowl,” however, it does not signify something in itself but is only a vocal sound. For a word is composed of many vocal sounds, but it has simplicity in signifying insofar as it signifies simple thought. Hence, a word inasmuch as it is a composite vocal sound can have a part which is a vocal sound, but inasmuch as it is simple in signifying it cannot have a signifying part. Thus syllables are indeed vocal sounds, but they are not vocal sounds signifying in themselves.
Peri.L6
Sciendum tamen quod in nominibus compositis, in quantum imponuntur ad significandum rem simplicem ex aliquo intellectu composito, partes secundum apparentiam aliquid significant, licet non secundum veritatem. Et ideo subdit quod in duplicibus, id est in compositis nominibus, syllabae, quae possunt etiam esse dictiones in compositionem nominis venientes, significant aliquid, scilicet in ipso composito et secundum quod sunt dictiones, non autem significant aliquid secundum se, prout sunt huius nominis partes, sed eo modo ut supra dictum est.
In contrast to this, it should be noted that in composite names, which are imposed to signify a simple thing from some composite understanding, the parts appear to signify something, although according to truth they do not. For this reason he adds that in compound words, that is, composite names, the syllables may be words contributing to the composition of a name, and therefore signify something, namely, in the composite, and according as they are words; but as parts of this kind of name they do not signify something in themselves, but in the way that has already been explained.
Peri.L6
80. Deinde cum dicit: Est autem oratio et cetera, excludit quemdam errorem.
Then, when he says: but all speech (17a1), he excludes a certain error.
Peri.L6
Fuerunt enim aliqui dicentes quod oratio et partes eius sunt significative naturaliter, non ad placitum. Ad quod probandum, utebantur tali ratione: Virtutis enim naturalis oportet esse instrumenta naturalia, quia natura non deficit in necessariis; potentia autem interpretativa est naturalis homini; ergo instrumenta eius sunt naturalia; instrumentum autem eius <est> oratio, quia per orationem virtus interpretativa interpretatur mentis conceptum: hoc enim dicimus instrumentum quo agens operatur; ergo oratio est aliquid naturale, non ex institutione humana significans, sed naturaliter.
Here he excludes the error of those who said that speech and its parts signify naturally rather than by convention. To prove their point they used the following argument. The instruments of a natural power must themselves be natural, for nature does not fail in regard to what is necessary. But the interpretive power is natural to man. Therefore, its instruments are natural. Now, the instrument of the interpretive power is speech, since it is through speech that expression is given to the conception of the mind—for we mean by an instrument that by which an agent operates. Therefore, speech is something natural, signifying, not from human institution, but naturally.
Peri.L6
81. Huic autem rationi, quae dicitur esse Platonis in libro qui intitulatur Cratylus, Aristoteles obvians dicit quod omnis oratio significativa est non sicut instrumentum, virtutis scilicet naturalis: instrumenta enim naturalis virtutis interpretativae sunt pulmo et guttur, quibus formatur vox, et lingua et labia et dentes, quibus litterati et articulati soni distinguuntur; oratio autem et partes <eius> sunt sicut effectus virtutis interpretativae per instrumenta praedicta, sicut etiam virtus motiva utitur instrumentibus naturalibus sicut brachiis et manibus ad faciendum opera artificialia. Unde et oratio et partes eius non sunt res naturales, sed quidam artificiales effectus. Et ideo subdit quod oratio significat secundum placitum, id est secundum institutionem humanae rationis et voluntatis, ut supra dictum est, sicut omnia artificialia causantur ex humana voluntate et ratione.
Aristotle refutes this argument, which is said to be that of Plato in the Cratylus, when he says that all speech is significant, but not as an instrument, that is, of a natural power. For the natural instruments of the interpretive power are the throat and lungs, by which vocal sound is formed, and the tongue, teeth, and lips, by which letters and articulate sounds are formulated. Rather, speech and its parts are effects of the interpretative power through the aforesaid instruments. For just as the motive power uses natural instruments, such as arms and hands, to make an artificial work, so the interpretative power uses the throat and other natural instruments to make speech. Hence, speech and its parts are not natural things, but certain artificial effects. This is the reason Aristotle adds here that speech signifies by convention, that is, according to the ordinance of human will and reason.
Peri.L6
Sciendum tamen quod, si virtutem interpretativam non attribuamus virtuti motivae, sed rationi, sic non est vis naturalis, sed supra omnem naturam corpoream, quia intellectus non est actus alicuius corporis, ut probatur in III De anima; ipsa autem ratio est quae movet virtutem motivam corporalem ad opera artificialia, quibus etiam ut instrumentis utitur ratio, non autem sunt instrumenta alicuius virtutis corporalis. Et hoc modo etiam ratio potest uti oratione et eius partibus quasi instrumentis, quamvis non naturaliter significent.
It should be noted, however, that if we do not attribute the interpretative power to a motive power, but to reason, then it is not a natural power but is beyond every corporeal nature, since thought is not an act of the body, as is proved in On the Soul.1 Moreover, it is reason itself that moves the corporeal motive power to make artificial works, which reason then uses as instruments; thus artificial works are not instruments of a corporeal power. Reason can also use speech and its parts in this way—that is, as instruments—although they do not signify naturally.
Peri.L6
L. 7 (Α.4, 17a2–17a7)The definition of enunciationDe enunciationis definitione
17a2. Enunciativa vero non omnis, sed in qua verum vel falsum est.
17a2. Yet not all speech is enunciative; but only speech in which there is truth or falsity.
Peri.L7
17a3. Non autem in omnibus, ut deprecatio oratio quidem est, sed neque vera neque falsa.
17a3. Truth and falsity is not present in all speech, however; a prayer, for example, is speech, but it is neither true nor false.
Peri.L7
17a5. Et ceterae quidem relinquuntur: rhetoricae enim vel poeticae convenientior consideratio est, enuntiativa vero praesentis est considerationis.
17a5. Let us therefore consider enunciative speech, which belongs to our present inquiry, and omit the other kinds, for the study of these belongs rather to rhetoric and poetics.
Peri.L7
82. Enunciativa vero non omnis et cetera. Postquam vero Philosophus determinavit de principiis enuntiationis, hic intendit determinare de ipsa enuntiatione.
Yet not all speech is enunciative. Having defined the principles of the enunciation, the Philosopher now begins to treat the enunciation itself.
Peri.L7
Et dividitur in partes duas:
This is divided into two parts.
Peri.L7
in prima determinat de enuntiatione absolute;
In the first, he examines the enunciation absolutely;
Peri.L7
in secunda de diversitate enuntiationum quae provenit secundum ea quae simplici enuntiationi adduntur,
in the second, the diversity of enunciations resulting from an addition to the simple enunciation.
Peri.L7
et hoc modo in secundo libro, ibi: Quoniam autem est de aliquo affirmatio et cetera.
The latter is treated in the second book, where he says: since an affirmation signifies something about a subject (19b5; [205]).
Peri.L7
Prima autem pars dividitur in partes tres:
The first part is divided into three parts.
Peri.L7
in prima definit enuntiationem;
In the first, he defines enunciation;
Peri.L7
in secunda dividit eam, ibi: Est autem una prima oratio et cetera;
in the second, he divides it, at: first affirmation, then negation (17a8; [88]);
Peri.L7
in tertia agit de oppositione partium eius ad invicem, ibi: Quoniam autem est enunciare et cetera.
in the third, he treats of the opposition of its parts to each other, at: since it is possible to enunciate (17a26; [109]).
Peri.L7
Circa primum tria facit:
About the first he does three things:
Peri.L7
primo proponit definitionem enuntiationis;
first, he states the definition;
Peri.L7
secundo ostendit quod per hanc definitionem differt enuntiatio ab aliis speciebus orationis, ibi: Non autem in omnibus et cetera;
second, he shows that this definition differentiates the enunciation from other species of speech, at: truth and falsity is not present in all speech, however (17a3; [85]);
Peri.L7
tertio ostendit quod de sola enuntiativa est tractandum, ibi: Et caeterae quidem relinquuntur et cetera.
third, he indicates that only the enunciation is to be treated in this book, at: let us therefore consider enunciative speech (17a5; [87]).
Peri.L7
83. Circa primum considerandum est quod oratio, quamvis non sit instrumentum alicuius virtutis naturaliter operantis, est tamen instrumentum rationis, ut supra dictum est; omne autem instrumentum oportet definiri ex suo fine, qui est usus instrumenti; usus autem orationis, sicut et omnis vocis significativae, est significare conceptionem intellectus, ut supra dictum est; operationes autem intellectus duae sunt, in quarum una non invenitur veritas et falsitas, in alia autem invenitur verum et falsum; et ideo orationem enuntiativam definit ex significatione veri et falsi, dicens quod non omnis oratio est enuntiativa, sed in qua verum et falsum est.
The point has just been made that speech, although it is not an instrument of a power operating naturally, is nevertheless an instrument of reason. Now, every instrument is defined by its end, which is the use of the instrument. The use of speech, as of every significant vocal sound, is to signify a conception of the intellect. But there are two operations of the intellect. In one are found truth and falsity; in the other, not. Aristotle therefore defines enunciative speech by the signification of the true and false: yet not all speech is enunciative, but only speech in which there is truth and falsity (17a2).
Peri.L7
Ubi considerandum est quod Aristoteles, mirabili brevitate usus, et divisionem orationis innuit in hoc quod dicit: non omnis enuntiativa, et definitionem enuntiationis in hoc quod dicit: sed in qua verum vel falsum est, ut intelligatur haec esse definitio enuntiationis: Enuntiatio est oratio in qua est verum vel falsum.
Note with what remarkable brevity he signifies the division of speech by saying: yet not all speech is enunciative, and the definition by saying: but only speech in which there is truth or falsity. This, then, is to be understood as the definition of the enunciation: Enunciation is speech in which there is truth or falsity.
Peri.L7
84. Dicitur autem in enunciatione esse verum vel falsum sicut in signo intellectus veri vel falsi; sed sicut in subiecto est verum vel falsum in mente, ut dicitur in VI Metaphysicae, in re autem sicut in causa, quia, ut dicitur in libro Praedicamentorum, eo quod res est vel non est, dicitur oratio vera vel falsa.
True or false is said to be in the enunciation as in a sign of true or false thought, but true or false is in the mind as in a subject, as is said in Metaphysics1 and in the thing as in a cause, as is said in the book Categories2—for it is from the facts of the case (that is, from a thing’s being so or not being so) that speech is true or false.
Peri.L7
85. Deinde cum dicit: Non autem in omnibus et cetera, ostendit quomodo per hanc definitionem differt enuntiatio ab aliis orationibus.
Next, he shows that this definition differentiates the enunciation from other speech, when he says: truth or falsity is not present in all speech, however (17a3).
Peri.L7
Et quidem de orationibus imperfectis manifestum est quod non significant verum vel falsum, quia, cum non faciant perfectum sensum in animo audientis, manifestum est quod non perfecte exprimunt iudicium rationis, in quo consistit verum vel falsum.
In the case of imperfect or incomplete speech, it is clear that it does not signify the true or false, since it does not make complete sense to the mind of the hearer and therefore does not completely express a judgment of reason in which the true or false consists.
Peri.L7
His igitur praetermissis, perfectae orationis, quae complet sententiam, quinque sunt species, videlicet enuntiativa, deprecativa, imperativa, interrogativa, vocativa.
Having made this point, however, it must be noted that there are five species of perfect speech that are complete in meaning: enunciative, deprecative, imperative, interrogative, and vocative.
Peri.L7
Non tamen est intelligendum quod solum nomen vocativi casus prolatum sit vocativa oratio, quia oportet aliquid partium significare separatim, ut supra dictum est; sed per vocativum revocatur sive excitatur animus audientis ad attendendum, non est autem vocativa oratio nisi plura coniungantur, ut cum dico, ‘O beate Petre!’ Harum autem orationum sola enuntiativa est in qua invenitur verum vel falsum, quia ipsa sola absolute significat [intellectus] mentis conceptum, in quo est verum vel falsum.
But it should be noted that a name alone in the vocative case is not vocative speech, for some of the parts must signify something separately, as was said above. So, although the mind of the hearer is provoked or aroused to attention by a name in the vocative case, there is not vocative speech, unless many words are joined together, as in, “O blessed Peter!” Of these species of speech, the enunciative is the only one in which there is truth or falsity, for it alone signifies the conception of the intellect absolutely, and it is in this that there is truth or falsity.
Peri.L7
86. Sed, quia intellectus seu ratio non solum concipit in se ipso veritatem rei, sed etiam ad eius officium pertinet secundum suum conceptum alia dirigere et ordinare, ideo necesse fuit ut, sicut per enuntiativam orationem significatur ipse mentis conceptus, ita etiam essent aliquae orationes significantes ordinem rationis secundum quem alia dirigit.
But the intellect, or reason, does not just conceive the truth of a thing. It also belongs to its office to direct and order others in accordance with what it conceives. Therefore, besides enunciative speech, which signifies the concept of the mind, there had to be other kinds of speech to signify the order of reason by which others are directed.
Peri.L7
Dirigitur autem ex ratione unius hominis alius homo ad tria:
Now, one man is directed by the reason of another in regard to three things:
Peri.L7
primo quidem ad attendendum mente, et ad hoc pertinet vocativa oratio;
first, to attend with his mind, and vocative speech relates to this;
Peri.L7
secundo ad respondendum voce, et ad hoc pertinet oratio interrogativa;
second, to respond with his voice, and interrogative speech relates to this;
Peri.L7
tertio ad exequendum in opere, et ad hoc pertinet quantum ad inferiores oratio imperativa, quantum autem ad superiores oratio deprecativa, ad quam etiam reducitur oratio optativa, quia respectu superioris homo non habet vim motivam nisi per expressionem sui desiderii.
third, to execute a work. In relation to this, imperative speech is used with regard to inferiors, deprecative with regard to superiors. Optative speech is reduced to the latter, for a man does not have the power to move a superior except by the expression of his desire.
Peri.L7
Quia igitur istae quatuor orationis species non significant ipsum conceptum intellectus in quo est verum vel falsum, sed quemdam ordinem ad hoc consequentem, inde est quod in nulla earum invenitur verum vel falsum, sed solum in enuntiativa, quae significat id quod mens de rebus concipit. Et inde est quod omnes modi orationum in quibus invenitur verum vel falsum sub enuntiatione continentur, <puta sub enutiativa oratio continetur> quam quidam dicunt iurativam vel suppositivam. Dubitativa autem ad interrogativam reducitur, sicut et optativa ad deprecativam.
These four species of speech do not signify the conception of the intellect in which there is truth or falsity, but a certain order following upon this. Consequently, truth or falsity is not found in any of them, but only in enunciative speech, which signifies what the mind conceives from things. It follows that all the modes of speech in which the true or false is found are contained under the enunciation, which some call jurative or suppositive. The dubitative, it should be noted, is reduced to the interrogative, as the optative is to the deprecative.
Peri.L7
87. Deinde cum dicit: Et ceterae quidem relinquuntur et cetera, ostendit quod de sola enuntiativa est agendum.
Then, Aristotle says: let us therefore consider enunciative speech (17a5). Here he points out that only enunciative speech is to be treated.
Peri.L7
Et dicit quod aliae quatuor orationis species sunt relinquendae, quantum pertinet ad praesentem intentionem, quia earum consideratio convenientior est rhetoricae vel poeticae scientiae, sed sola enuntiativa oratio est praesentis considerationis.
And he says that the other four species must be omitted as far as the present intention is concerned, because their investigation belongs rather to the sciences of rhetoric or poetics; but enunciative speech alone belongs to the present consideration.
Peri.L7
Cuius ratio est quia consideratio huius libri directe ordinatur ad scientiam demonstrativam, in qua animus hominis per rationem inducitur <ad assentiendum> vero ex his quae sunt propria rei, et ideo demonstrator non utitur ad suum finem nisi enuntiativis orationibus significantibus res secundum quod earum veritas est in anima; sed rhetor et poeta inducunt ad assentiendum ei quod intendunt, non solum per ea quae sunt propria rei, sed etiam per dispositiones audientis; unde rhetores et poetae plerumque movere auditores nituntur provocando eos ad aliquas passiones, ut Philosophus dicit in sua Rhetorica; et ideo consideratio dictarum specierum orationis, quae spectat ad ordinationem audientis in aliquid, cadit proprie sub consideratione rhetoricae vel poeticae, ratione sui significati, ad considerationem autem grammaticae prout in eis consideratur congrua vocum constructio.
The reason is that this book is ordered directly to demonstrative science, in which the mind of man is led by an act of reasoning to assent to truth from those things that are proper to the thing. To this end the demonstrator uses only enunciative speech, which signifies things according as truth about them is in the mind. The rhetorician and the poet, on the other hand, induce assent to what they intend not only through what is proper to the thing, but also through the dispositions of the hearer. Hence, rhetoricians and poets for the most part strive to move their auditors by arousing certain passions in them, as the Philosopher says.1 This kind of speech, therefore, which is concerned with the ordination of the hearer toward something, belongs to the consideration of rhetoric or poetics by reason of its intent, but to the consideration of the grammarian as regards a suitable construction of the vocal sounds.
Peri.L7
L. 8 (Α.5–6, 17a8–17a26)The division of enunciation into simple and composite, affirmative and negativeDe divisione enunciationis in simplicem et compositam, affirmativam et negativam
17a8. Est autem una prima oratio enuntiativa affirmatio, deinde negatio, aliae vero coniunctione unae.
17a8. First affirmation, then negation, is enunciative speech that is one; the others are one by conjunction.
Peri.L8
17a9. Necesse est autem omnem orationem enuntiativam ex verbo esse vel casu. Et enim hominis rationi si non aut ‘est’ aut ‘erit’ aut ‘fuit’ aut aliquid huiusmodi addatur, nondum est oratio enuntiativa.
17a9. Every enunciative speech, however, must contain a verb or a mode of the verb; for the definition of man, if “is” or “was” or “will be” or something of the kind is not added, is not yet enunciative speech.
Peri.L8
17a13. Quare autem unum quiddam est et non multa ‘animal gressibile bipes’,—neque enim in eo quod partes propinquae dicuntur, unum erit,—est alterius hoc tractare negocii.
17a13. But then the question arises as to why the definition “terrestrial biped animal” is something one and not many—for clearly it will not be one by reason of the words being said in juxtaposition—but this belongs to another subject of inquiry.
Peri.L8
17a15. Est autem una oratio enuntiativa quae unum significat vel coniunctione una, plures autem quae plura et non unum vel inconiunctione.
17a15. Enunciative speech is one when it signifies one thing or is one by conjunction; but it is many when it signifies many things and not one, or many things not joined together.
Peri.L8
17a17. Nomen ergo et verbum dictio sit sola, quoniam non est dicere sic aliquid significantem voce enuntiare, vel aliquo interrogante, vel non sed ipso proferente.
17a17. Let us call the name or the verb a word only, since to speak in this way is not to signify something with the voice so as to enunciate, either in reply to someone asking a question or by one’s own choice.
Peri.L8
17a20. Harum autem haec quidem simplex est enuntiatio, ut aliquid de aliquo vel aliquid ab aliquo, haec autem ex his coniuncta est velut oratio quaedam iam composita.
17a20. Of enunciations that are one, simple enunciation is one kind, that is, something affirmed of something or something denied of something; the other kind is composite, that is, speech composed of these simple enunciations.
Peri.L8
17a22. Est autem simplex enuntiatio vox significativa de eo quod est aliquid vel non est, quemadmodum tempora divisa sunt. Affirmatio vero est enuntiatio alicuius de aliquo, negatio vero enuntiatio alicuius ab aliquo.
17a22. A simple enunciation is vocal sound signifying that something belongs or does not belong to a subject according to the divisions of time. Affirmation is the enunciation of something about something; negation the enunciation of something separated from something.
Peri.L8
88. Est autem una prima oratio et cetera. Postquam Philosophus definivit enunciationem, hic dividit eam.
First affirmation, then negation, is enunciative speech that is one. Having defined the enunciation the Philosopher now divides it.
Peri.L8
Et dividitur in partes duas:
And this is in two parts.
Peri.L8
in prima ponit divisionem enuntiationis;
First, he gives the division;
Peri.L8
in secunda manifestat eam, ibi: Necesse est autem et cetera.
second, he manifests it, at: every enunciative speech however, must contain a verb (17a9; [94]).
Peri.L8
89. Circa primum considerandum est quod Aristoteles sub breviloquio duas divisiones enuntiationis ponit.
It should be noted that Aristotle in his concise way gives two divisions of the enunciation.
Peri.L8
Quarum una est quod enuntiationum quaedam est una simpliciter, quaedam est coniunctione una. Sicut etiam in rebus quae sunt extra animam aliquid est unum simpliciter, sicut indivisibile vel continuum, aliquid est unum colligatione aut compositione aut ordine: quia enim ens et unum convertuntur, necesse est sicut omnem rem, ita et omnem enuntiationem aliqualiter esse unam.
The first is the division into one simply and one by conjunction. This parallels things outside of the soul where there is also something one simply—for instance, the indivisible or the continuum—and something one either by aggregation or composition or order. In fact, since being and one are convertible, every enunciation must in some way be one, just as every thing is.
Peri.L8
90. Alia vero subdivisio enuntiationis est quod, si enuntiatio sit una, aut est affirmativa aut negativa.
The other is a subdivision of the enunciation; if the enunciation is one, it is either affirmative or negative.
Peri.L8
Enuntiatio autem affirmativa est prior negativa, triplici ratione, secundum tria quae supra posita sunt,
The affirmative enunciation is prior to the negative for three reasons, which are related to three things already stated.
Peri.L8
ubi dictum est quod <vox> est signum intellectus et intellectus est signum rei; ex parte igitur vocis, affirmativa enuntiatio est prior quia est simplicior: negativa enim enuntiatio addit supra affirmativam particulam negativam;
It was said that vocal sound is a sign of thought and thought a sign of the thing. Accordingly, with respect to vocal sound, affirmative enunciation is prior to negative because it is simpler, for the negative enunciation adds a negative particle to the affirmative.
Peri.L8
ex parte intellectus etiam affirmativa enuntiatio, quae significat compositionem intellectus, est prior negativa, quae significat divisionem eiusdem: divisio autem naturaliter posterior est compositione, nam non est divisio nisi compositorum, sicut non est corruptio nisi generatorum;
With respect to thought, the affirmative enunciation, which signifies composition by the intellect, is prior to the negative, which signifies division, for division is posterior by nature to composition, since division is only of composite things (just as corruption is only of generated things).
Peri.L8
ex parte etiam rei, affirmativa enuntiatio, quae significat esse, prior est quam negativa, quae significat non esse, sicut habitus naturaliter prior est privatione.
With respect to the thing, the affirmative enunciation, which signifies “to be,” is prior to the negative, which signifies “not to be,” as the having of something is naturally prior to the privation of it.
Peri.L8
91. Dicit ergo quod oratio enuntiativa una et prima est affirmatio, id est affirmativa enuntiatio. Et contra hoc quod dixerat prima, subdit: deinde negatio, id est negativa enuntiatio, quia est posterior affirmativa, ut dictum est. Contra id autem quod dixerat una, scilicet simpliciter, subdit quod quaedam aliae sunt unae, non simpliciter, sed coniunctione, ita scilicet quod quaelibet earum est coniunctione una.
What he says, then, is this: affirmation (that is, affirmative enunciation) is one and the first enunciative speech (17a8). And in opposition to first, he adds: then negation, that is, negative speech, for it is posterior to affirmative, as we have said. In opposition to one, that is, one simply, he adds, certain others are one not simply, but by conjunction, namely, that any of them is one by conjunction.
Peri.L8
92. Ex hoc autem quod hic dicitur argumentatur Alexander quod divisio enuntiationis in affirmationem et negationem non est divisio generis in species, sed divisio nominis multiplicis in sua significata: genus enim univoce praedicatur de suis speciebus, non secundum prius et posterius, unde Aristoteles noluit quod ens esset genus commune omnium, quia per prius praedicatur de substantia quam de novem generibus accidentium.
From what Aristotle says here, Alexander argues that the division of enunciation into affirmation and negation is not a division of a genus into species, but a division of a multiple name into its meanings, for a genus is not predicated according to the prior and posterior, but is predicated univocally of its species. This is the reason Aristotle would not grant that being is a common genus of all things, for it is predicated first of substance, and then of the nine genera of accidents.
Peri.L8
93. Sed dicendum est quod unum dividentium aliquod commune potest esse prius altero dupliciter:
However, in the division of that which is common, one of the dividing members can be prior to another in two ways:
Peri.L8
uno modo secundum proprias rationes aut naturas dividentium;
according to the proper notions or natures of the dividing members,
Peri.L8
alio modo secundum participationem rationis illius communis quod in ea dividitur;
or according to the participation of that common notion that is divided in them.
Peri.L8
primum autem non tollit univocationem generis, ut manifestum est in numeris, in quibus binarius secundum propriam rationem naturaliter prior est ternario, sed tamen aequaliter participant rationem communis, scilicet numeri: ita enim est ternarius multitudo mensurata per unum sicut et binarius;
The first of these does not destroy the univocity of a genus, as is evident in numbers. Twoness, according to its proper notion, is naturally prior to threeness, yet they equally participate in the notion of their genus, that is, number; for both a multitude consisting of three and a multitude consisting of two is measured by one.
Peri.L8
sed secundum impedit univocationem generis, et propter hoc ens non potest esse genus substantiae et accidentis, quia in ipsa ratione entis prioritatem habet substantia, quae est ens per se, respectu accidentis, quod est ens per aliud et in alio. Sic ergo affirmatio secundum propriam rationem est prior negatione, tamen aequaliter participant rationem enuntiationis quam supra posuit, quod enuntiatio est oratio in qua est verum vel falsum.
The second, however, does impede the univocity of a genus. This is why being cannot be the genus of substance and accident, for in the very notion of being, substance, which is being in itself, has priority in respect to accident, which is being through another and in another. Applying this distinction to the matter at hand, we see that affirmation is prior to negation in the first way—that is, according to its notion—yet they equally participate in the definition Aristotle has given of the enunciation, that is, speech in which there is truth or falsity.
Peri.L8
94. Deinde cum dicit: Necesse est autem omnem orationem et cetera, manifestat propositas divisiones.
Where he says: every enunciative speech, however, must contain a verb or a mode of the verb (17a9), he explains the divisions.
Peri.L8
Et primo manifestat primam,
He gives two explanations:
Peri.L8
scilicet quod enuntiatio vel est una simpliciter vel coniunctione;
one is of the division of enunciation into one simply and by conjunction;
Peri.L8
secundo manifestat secundam, scilicet quod enuntiatio simpliciter una vel est affirmativa vel negativa, ibi: Est autem simplex enunciatio et cetera.
the second is of the division of the enunciation which is one simply into affirmative or negative, at: a simple enunciation is vocal sound (17a22; [106]).
Peri.L8
Circa primum duo facit: primo praemittit quaedam quae sunt necessaria ad propositi manifestationem; secundo manifestat propositum, ibi: Est autem una oratio etc.
Before he explains the first division, that is, into one simply and one by conjunction, he states certain things that are necessary for the evidence of the explanation, and then explains the division where he says: enunciative speech is one when it signifies one thing (17a15; [99]).
Peri.L8
95. Circa primum duo proponit.
About the first he sets out two things.
Peri.L8
Primo dicit quod omnem orationem enuntiativam necesse est constare ex verbo, quod est praesentis temporis, vel ex casu verbi, quod est temporis praeteriti vel futuri (tacet autem de verbo infinito, quia eumdem usum habet in enuntiatione sicut et verbum negativum). Manifestat autem quod dixerat per hoc quod non solum unicum nomen sine verbo <non> facit enuntiationem, sed nec etiam oratio imperfecta: definitio enim oratio quaedam est, et tamen si rationi, id est definitioni, hominis non addatur aut ‘est’, quod est verbum, aut ‘erit’ aut ‘fuit’, quae sunt casus verbi, sive aliquid huiusmodi, id est aliquod aliud verbum seu casus verbi, nondum est oratio enuntiativa.
He states the first thing that is necessary for his explanation when he says (17a9) that every enunciative speech must contain a verb in present time, or a case of the verb, that is, in past or future time. (The infinite verb is not mentioned because it has the same function in the enunciation as the negative verb.) To manifest this, he shows that one name, without a verb, does not even constitute imperfect enunciative speech, let alone perfect speech. Definition, he points out, is a certain kind of speech, and yet if the verb “is” or modes of the verb such as “will be” or “was” or something of the kind is not added to the notion of man, that is, to the definition, it is not enunciative speech.
Peri.L8
96. Potest autem esse dubitatio, cum enuntiatio constet ex nomine et verbo, quare non facit mentionem de nomine sicut de verbo?
But, one might ask, why mention the verb and not the name, for the enunciation consists of a name and a verb?
Peri.L8
Ad quod tripliciter responderi potest.
This can be answered in three ways.
Peri.L8
Primo quidem, quia nulla omnino enuntiatio sine verbo vel casu verbi invenitur, invenitur autem aliqua enuntiatio sine nomine, puta cum utimur infinitivis verborum loco nominum, ut cum dicitur: ‘Currere est moveri’.
First, because enunciative speech is not attained without a verb or a mode of the verb, but it is without a name, such as when infinitive forms of the verb are used in place of names, as in “to run is to be moving.”
Peri.L8
Secundo et melius, quia, sicut supra dictum est, verbum est nota eorum quae de altero praedicantur, praedicatum autem est principalior pars enuntiationis, eo quod est pars formalis et completiva ipsius (unde et vocatur apud Graecos propositio categorica, id est praedicativa), denominatio autem fit a forma, quae dat speciem rei; et ideo potius fecit mentionem de verbo, tanquam de parte principaliori et formaliori. Cuius signum est quod enuntiatio categorica dicitur affirmativa vel negativa solum ratione verbi, quod affirmatur vel negatur, sicut et conditionalis dicitur affirmativa vel negativa ex eo quod affirmatur vel negatur coniunctio a qua denominatur.
A second and better reason for speaking only of the verb is that the verb is a sign of what is predicated of another. Now, the predicate is the principal part of the enunciation because it is the formal part and completes it. This is the reason the Greeks called the enunciation a categorical—that is, predicative—proposition. It should also be noted that denomination is made from the form which gives species to the thing. He speaks of the verb, then, but not the name, because it is the more principal and formal part of the enunciation. A sign of this is that the categorical enunciation is said to be affirmative or negative solely by reason of the verb being affirmed or denied, and the conditional enunciation is said to be affirmative or negative by reason of the conjunction by which it is denominated being affirmed or denied.
Peri.L8
Tertio potest dici, et adhuc melius, quod non erat hic intentio Aristotelis ostendere quod nomen vel verbum non sufficiat ad enuntiationem complendam: hoc enim supra manifestaverat tam de nomine quam de verbo; sed, quia dixerat quod quaedam enuntiatio est una simpliciter, quaedam autem coniunctione una, posset aliquis intelligere quod illa quae est una simpliciter careret omni compositione; sed ipse hoc excludit per hoc quod in omni enuntiatione oportet esse verbum, quod importat compositionem quam non est intelligere sine compositis, ut supra dictum est; nomen autem non importat compositionem, et ideo non exigit praesens intentio ut de nomine faceret mentionem, sed solum de verbo.
A third and even better reason is that Aristotle did not intend to show that the name or verb is not sufficient for a complete enunciation, for he explained this earlier. Rather, he is excluding a misunderstanding that might arise from his saying that one kind of enunciation is one simply and another kind is one by conjunction. Some might think this means that the kind that is one simply lacks all composition. But he excludes this by saying that there must be a verb in every enunciation; for the verb implies composition and composition cannot be understood apart from the things composed, as he said earlier. The name, on the other hand, does not imply composition, and therefore did not have to be mentioned.
Peri.L8
97. Secundo; ibi: Quare autem unum quiddam et cetera, proponit aliud quod est necessarium ad manifestationem propositi, scilicet quod hoc quod dico, ‘animal gressibile bipes’, quod est definitio hominis, est unum et non multa (et eadem ratio est de universis aliis definitionibus); sed huius rationem assignare dicit esse alterius negotii: pertinet enim ad metaphysicum, unde in VII et in VIII Metaphysicae huius ratio assignatur, quia scilicet differentia advenit generi non per accidens, sed per se, tanquam determinativa ipsius, per modum quo materia determinatur per formam; nam a materia sumitur genus, a forma autem differentia, unde, sicut ex materia et forma fit vere unum et non multa, ita etiam ex genere et differentia.
The other point necessary for the evidence of the first division is made where he says: but then the question arises (17a13). He indicates by this that “terrestrial biped animal”, which is a definition of man, is one and not many. The reason it is one is the same as in the case of all definitions but, he says, to assign the reason belongs to another subject of inquiry. It belongs, in fact, to metaphysics, and he assigns the reason in Metaphysics 7.12, 1037b7 and 8.6, 1045a6. It is this: the difference does not accrue to the genus accidentally, but in itself, and is determinative of it in the way in which form determines matter; for the genus is taken from matter, the difference from form. Thus, just as one thing—not many—comes to be from form and matter, so one thing comes to be from the genus and difference.
Peri.L8
98. Excludit autem quamdam rationem huius unitatis, quam quis posset suspicari, ut scilicet propter hoc definitio sit unum, quia partes eius dicuntur propinquae, scilicet sine aliqua interpositione coniunctionis vel morae. Et quidem non-interruptio prolationis necessaria est ad unitatem definitionis, quia, si interponeretur coniunctio partibus definitionis, iam secunda non determinaret primam, sed significarentur ut actu multae; et idem operatur interpositio morae, qua utuntur rhetores loco coniunctionis. Unde ad unitatem definitionis requiritur quod partes eius proferantur sine coniunctione et interpolatione, quia et in re naturali, cuius est definitio, nihil cadit medium inter materiam et formam; sed praedicta non-interruptio non sufficit ad unitatem definitionis, quia contingit etiam hanc continuitatem prolationis servari in his quae non sunt simpliciter unum, sed per accidens, ut si dicam: ‘Homo albus musicus’.
The reason for the unity of this definition might be supposed by some to be only that of juxtaposition of the parts, that is, that this definition is said to be one only because the parts are said to be side by side without conjunction or pause. But he excludes such a notion of its unity. Now, it is true that non-interruption of locution is necessary for the unity of a definition, for if a conjunction were put between the parts, the second part would not determine the first immediately and the many would consequently signify many in act. The pause used by rhetoricians in place of a conjunction would do the same thing. Hence it is a requirement for the unity of a definition that its parts be uttered without conjunction and interpolation, for in the natural thing, whose definition it is, nothing mediates between matter and form. However, non-interruption of locution is not the only thing that is needed for unity of the definition, for there can be continuity of utterance in regard to things that are one accidentally and not simply, like “white musical man.”
Peri.L8
Sic igitur Aristoteles valde subtiliter manifestavit quod absoluta unitas enuntiationis non impeditur neque per compositionem quam importat verbum, neque per multitudinem nominum ex quibus constat definitio; et est eadem ratio utrobique, nam praedicatum comparatur ad subiectum ut forma ad materiam, et similiter differentia ad genus, ex forma autem et materia fit unum simpliciter.
Aristotle has therefore manifested very subtly that absolute unity of the enunciation is not impeded either by the composition which the verb implies or by the multitude of names from which a definition is established. And the reason is the same in both cases, that is, the predicate is related to the subject as form to matter, as is the difference to a genus. But from form and matter a thing that is one simply comes into existence.
Peri.L8
99. Deinde cum dicit: Est autem una et cetera, accedit ad manifestandum praedictam divisionem.
He begins to explain the division when he says: enunciative speech is one when it signifies one thing (17a15).
Peri.L8
Et primo manifestat ipsum commune quod dividitur, quod est enuntiatio una;
First, he makes evident the common thing that is divided (namely, the enunciation as it is one);
Peri.L8
secundo manifestat partes divisionis secundum proprias rationes, ibi: Harum autem haec quidem simplex et cetera.
second, he makes the parts of the division evident according to their own proper notions, at: of enunciations that are one, simple enunciation is one kind (17a20; [105]).
Peri.L8
Circa primum duo facit: primo manifestat praemissam divisionem; secundo concludit quod ab utroque membro divisionis nomen et verbum excluduntur, ibi: Nomen ergo et verbum et cetera.
After he has made the division of the common thing evident—namely, enunciation—he then concludes that the name and the verb are excluded from each member of the division at: let us call the name or the verb a word only (17a17; [104]).
Peri.L8
Oppositum autem unitati est pluralitas, et ideo per modos unitatis manifestat modos pluralitatis.
Now, plurality is opposed to unity. Therefore, he is going to manifest the unity of the enunciation through the modes of plurality.
Peri.L8
100. Dicit ergo quod oratio enuntiativa dicitur vel una absolute, quia scilicet unum significat, vel una secundum quid, quia scilicet est una coniunctione; per oppositum autem est intelligendum quod enuntiationes plures sunt vel ex eo quod plura significant et non unum, quod opponitur primo modo unitatis, vel ex eo quod absque coniunctione proferuntur.
He begins his explanation (17a15) by saying that enunciation is either one absolutely, that is, it signifies one thing said of one thing, or one relatively, that is, it is one by conjunction. In opposition to these are the enunciations that are many, either because they signify not one but many things, which is opposed to the first mode of unity, or because they are uttered without a connecting particle, which is opposed to the second mode of unity.
Peri.L8
101. Circa quod considerandum est, secundum Boethium, quod unitas et pluralitas orationis refertur ad significationem, simplex autem et compositum attenditur secundum ipsas voces; et ideo enuntiatio quandoque quidem est una et simplex, puta cum solum ex nomine et verbo componitur quae unum significant, ut cum dico: ‘Homo est albus’; est autem oratio una, sed composita, quae quidem unam rem significat, sed tamen composita est vel ex pluribus terminis, sicut si dicam: ‘Animal rationale mortale currit’, vel ex pluribus enuntiationibus, sicut patet in conditionalibus, quae unum et non multa significant. Similiter autem in enuntiatione quandoque est pluralitas cum simplicitate, puta cum in oratione ponitur aliquod nomen multa significans, ut si dicam: ‘Canis latrat’, haec oratio plures est, quia multa significat, et tamen simplex est; quandoque vero est in enuntiatione pluralitas et compositio, puta cum ponuntur plures termini in subiecto vel praedicato, ex quibus non fit unum, sive interveniat coniunctio sive non; puta si dicam: ‘Homo albus musicus disputat’, vel: ‘Homo albus et musicus disputat’; et simile est si coniungantur multae enuntiationes, sive cum coniunctione sive sine coniunctione, ut si dicam: ‘Socrates currit, Plato disputat’. Et secundum hoc, sensus litterae est quod oratio enuntiativa est una quae unum significat, non solum si sit simplex, sed etiam si sit coniunctione una; et similiter orationes plures dicuntur quae plura et non unum significant, non solum quando interponitur aliqua coniunctio vel inter nomina seu verba, vel etiam inter ipsas enuntiationes, sed vel inconiunctione, id est si absque interposita coniunctione plura significat, vel <quia> est unum nomen aequivocum multa significans, vel quia ponuntur multa nomina absque interposita coniunctione, ex quorum significatis non fit unum, ut si dicam: ‘Homo albus musicus currit’.
Boethius interprets this passage in the following way. Unity and plurality of speech refers to what is signified, whereas simple and composite is related to the vocal sounds. Accordingly, an enunciation is sometimes one and simple, namely, when one thing is signified by the composition of name and verb, as in “Man is white.” Sometimes it is one and composite. In this case it signifies one thing, but is composed either from many terms, as in “A mortal rational animal is running,” or from many enunciations, as in conditionals that signify one thing and not many. On the other hand, sometimes there is plurality along with simplicity, namely, when a name signifying many things is used, as in “The dog barks,” in which case the enunciation is many because it signifies many things,1 but it is simple as far as vocal sound is concerned. But sometimes there is plurality and composition, namely, when many things are posited on the part of the subject or predicate from which one thing does not result, whether a conjunction intervenes or not, as in “The musical white man is arguing,” or “The musical and white man is arguing.” This is also the case if there are many enunciations joined together, with or without connecting particles, as in “Socrates runs, Plato argues.” According to this exposition, the meaning of the passage in question is this: an enunciation is one when it signifies one thing said of one thing (and this is the case whether the enunciation is one simply or is one by conjunction); an enunciation is many when it signifies not one but many things, and this not only when a conjunction is inserted between either the names or verbs or between the enunciations themselves, but even if there are many things that are not conjoined. In the latter case, they signify many things either because an equivocal name is used or because many names signifying many things from which one thing does not result are used without conjunctions, as in “The white musical man is running.”
Peri.L8
102. Sed haec expositio non videtur esse secundum intentionem Aristotelis;
However, this exposition does not seem to be what Aristotle had in mind.
Peri.L8
primo quidem, quia per disiunctionem quam interponit videtur distinguere inter orationem unum significantem et orationem quae est coniunctione una;
First of all, the disjunction he inserts seems to indicate that he is distinguishing between speech signifying one thing and speech which is one by conjunction.
Peri.L8
secundo quia Aristotiles supra dixerat quod est unum quiddam et non multa ‘animal gressibile bipes’, quod autem est coniunctione unum, non est unum et non multa, sed est unum ex multis.
In the second place, he has just said that “terrestrial biped animal” is something one and not many (17a13); moreover, what is one by conjunction is not one, and not many, but one from many.
Peri.L8
Et ideo melius videtur dicendum quod, quia Aristoteles supra dixerat aliquam enuntiationem esse unam et aliam coniunctione unam, vult hic manifestare quae sit una; et, quia iam supra ostendit quod multa nomina simul coniuncta sunt unum, sicut ‘animal gressibile bipes’, dicit consequenter quod enuntiatio est iudicanda una non ex unitate nominis, sed ex unitate significati, etiam si sint plura nomina quae unum significent; vel, si sit aliqua enuntiatio una quae multa significet, non erit una simpliciter, sed coniunctione una; et, secundum hoc, haec enuntiatio: ‘Animal gressibile bipes est risibile’, non est una quasi coniunctione una, ut in prima expositione dicebatur, sed quia unum significat.
Hence it seems better to say that since he has already said that one kind of enunciation is one simply and another kind is one by conjunction, he is showing here what one enunciation is. Having said, then, that many names joined together are something one—as in the example “terrestrial biped animal”—he goes on to say that an enunciation is to be judged as one, not from the unity of the name but from the unity of what is signified, even if there are many names signifying the one thing. If an enunciation which signifies many things is one, it will not be one simply, but one by conjunction. Hence, the enunciation “A terrestrial biped animal is risible” is not one in the sense of one by conjunction (as the first exposition would have it), but because it signifies one thing.
Peri.L8
103. Quia autem oppositum per oppositum manifestatur, ostendit consequenter quae dicuntur plures enuntiationes, et ponit duos modos pluralitatis.
Then—because an opposite is manifested through an opposite—he goes on to show which enunciations are many, and he posits two modes of plurality.
Peri.L8
Primus est quod plures dicuntur enuntiationes quae significant plura; contingit autem aliqua plura significari in aliquo uno communi, sicut cum dico: ‘Animal est sensibile’, sub hoc communi quod est animal multa continentur, et tamen haec enuntiatio est una et non plures; et ideo addit et non unum; sed melius est ut dicatur hoc esse additum propter definitionem, quae significat multa quae sunt unum. Et hic modus pluralitatis opponitur primo modo unitatis.
Enunciations are said to be many which signify many things. Many things may be signified in some one common thing, however. For example, when I say, “An animal is a sentient being,” many things are contained under the one common thing, animal, but such an enunciation is still one, not many. Therefore, Aristotle adds, and not one. It would be better to say, however, that this is added because of definition, which signifies many things that are one. The mode of plurality he has spoken of thus far is opposed to the first mode of unity.
Peri.L8
Secundus modus pluralitatis est quando enuntiationes non solum plura significant, sed etiam illa plura nullatenus coniunguntur. Et hic modus pluralitatis opponitur secundo modo unitatis. Et secundum hoc patet quod secundus modus unitatis non opponitur primo modo pluralitatis; ea autem quae non sunt opposita possunt simul esse, unde manifestum est enuntiationem quae est coniunctione una esse etiam plures in quantum significat plura et non unum.
The second mode of plurality covers enunciations that not only signify many things but many that are in no way joined together. This mode is opposed to the second mode of unity. Thus it is evident that the second mode of unity is not opposed to the first mode of plurality. Now, those things that are not opposed can be together. Therefore, the enunciation that is one by conjunction is also many insofar as it signifies many and not one.
Peri.L8
Secundum hoc ergo possumus accipere tres modos enuntiationis:
According to this understanding of the text there are three modes of the enunciation:
Peri.L8
nam quaedam est simpliciter una, in quantum unum significat;
the enunciation that is one simply inasmuch as it signifies one thing;
Peri.L8
quaedam autem est simpliciter plures, in quantum plura significat, sed una secundum quid, in quantum est coniunctione <una>;
the enunciation that is many simply inasmuch as it signifies many things, but is one relatively inasmuch as it is one by conjunction;
Peri.L8
quaedam vero sunt simpliciter plures, quae neque significant unum neque aliqua coniunctione uniuntur.
finally, the enunciations that are many simply—those that do not signify one thing and are not united by any conjunction.
Peri.L8
Ideo autem Aristoteles quatuor ponit et non solum tria, quia quandoque est plures enuntiatio quae plura significat, non tamen est coniunctione una, puta si ponatur ibi nomen multa significans.
Aristotle posits four kinds of enunciation rather than three, for an enunciation is sometimes many because it signifies many things, and yet is not one by conjunction; a case in point would be an enunciation in which a name signifying many things is used.
Peri.L8
104. Deinde cum dicit: Nomen ergo et verbum et cetera, excludit ab unitate orationis nomen et verbum.
Where he says: let us call the name or the verb a word only (17a17), he excludes the name and the verb from the unity of speech.
Peri.L8
Dixerat enim quod una enuntciatio est quae unum significat; posset autem aliquis intelligere quod sic unum significaret sicut nomen vel verbum unum significat; et ideo ad hoc excludendum subdit: Nomen et verbum dictio sit sola, id est ita sit dictio quod non enuntiatio; et videtur quod, ex modo loquendi, quod ipse imposuerit hoc nomen ad significandum partes orationis. Quod autem nomen vel verbum sit sola dictio et non enuntiatio, manifestat per hoc quod non potest dici quod ille enuntiet qui sic significat aliquid voce sicut nomen vel verbum significat.
His reason for making this point is that his statement that an enunciation is one inasmuch as it signifies one thing might be taken to mean that an enunciation signifies one thing in the same way the name or verb signify one thing. To prevent such a misunderstanding, he says: let us call the name or the verb a word only, that is, a locution which is not an enunciation. From his mode of speaking, it would seem that Aristotle himself imposed the name “word” to signify such parts of the enunciation. Then, he shows that a name or verb is only a word by pointing out that we do not say that a person is enunciating when he signifies something in vocal sound in the way in which a name or verb signifies.
Peri.L8
Et ad hoc manifestandum consequenter insinuat duos modos utendi enuntiatione:
To manifest this, he suggests two ways of using the enunciation.
Peri.L8
quandoque enim utimur ea quasi interroganti respondentes, puta si quaeratur: ‘Quid fit in scholis?’, respondemus: ‘Magister disputat’;
Sometimes we use it to reply to questions; for example, if someone asks, “What happens in school?” we answer, “The teacher argues.”
Peri.L8
quandoque autem utimur ea propria sponte, a nullo interrogati;
At other times, we use the enunciation not in reply to a question, but of our own accord.
Peri.L8
dicit ergo quod ille qui significat aliquid unum nomine vel verbo, non enuntiat vel sicut enuntiat ille qui profert enuntiationem aliquo interrogante, vel sicut enuntiat ille qui profert enuntiationem non aliquo interrogante sed ipso sponte proferente.
What Aristotle is saying, then, is that the person who signifies something one by a name or a verb is not enunciating in the way in which either the person who replies to a question or who utters an enunciation of his own accord is enunciating.
Peri.L8
Introduxit autem hoc, quia simplex nomen vel verbum, quando respondetur ad interrogationem, videtur verum et falsum significare, quod est proprium enuntiationis; sed hoc non competit nomini vel verbo nisi secundum quod intelligitur coniunctum cum alia parte proposita in interrogatione, ut si quaerenti: ‘Quis legit in scholis?’, respondeatur: ‘Magister’, subintelligitur: ‘legit’.
He introduces this point because the simple name or verb, when used in reply to a question, seems to signify truth or falsity, and truth or falsity is what is proper to the enunciation. Truth and falsity is not proper, however, to the name or verb unless it is understood as joined to another part proposed in a question; for example, if someone should ask, “Who reads in school?” we would answer, “The teacher,” understanding the verb, “reads.”
Peri.L8
Si ergo ille qui enuntiat aliquid nomine vel verbo non enuntiat, manifestum est quod enuntiatio non sic unum significat sicut nomen vel verbum. Hoc autem inducit sicut conclusionem eius quod supra praemiserat: Necesse est omnem orationem enuntiativam ex verbo esse vel casu.
If, then, something expressed by a name or verb is not an enunciation, it is evident that the enunciation does not signify one thing in the same way as the name or verb signify one thing. Aristotle draws this by way of a conclusion from what was said earlier: every enunciative speech must contain a verb or a mode of the verb (17a9).
Peri.L8
105. Deinde cum dicit: Harum autem haec quidem et cetera, manifestat praemissam divisionem secundum rationes partium.
Then when he says: of enunciations that are one, simple enunciation is one kind (17a20), he manifests the division of enunciation by the natures of the parts.
Peri.L8
Dixerat enim quod una enuntiatio est quae significat unum vel quae est coniunctione una; ratio autem huius distinctionis est ex eo quod unum natum est dividi per simplex et compositum; et ideo dicit: Harum autem, scilicet enuntiationum in quibus dicitur unum, vel quia significat unum simpliciter vel quia est coniunctione una, haec quidem est simplex enuntiatio, quae scilicet unum significat; sed, ne intelligatur quod sic unum significet sicut nomen vel verbum, ad hoc excludendum subdit: ut aliquid de aliquo, scilicet per modum compositionis, vel aliquid ab aliquo, scilicet per modum divisionis; haec autem ex his coniuncta, quae dicitur scilicet coniunctione una, est velut oratio iam composita. Quasi dicat: hoc modo enuntiationis unitas dividitur in duo praemissa sicut aliquod unum dividitur in simplex et compositum.
He has said that the enunciation is one when it signifies one thing or is one by conjunction. The basis of this division is the nature of one, which is such that it can be divided into simple and composite. Hence, Aristotle says: of these, that is, enunciations into which one is divided, which are said to be one either because the enunciation signifies one thing simply or because it is one by conjunction, simple enunciation is one kind, that is, the enunciation that signifies one thing. And to exclude the understanding of this as signifying one thing in the same way as the name or the verb signifies one thing, he adds: something affirmed of something, that is, by way of composition, or something denied of something, that is, by way of division. The other kind—the enunciation that is said to be one by conjunction—is composite, that is, speech composed of these simple enunciations. In other words, he is saying that the unity of the enunciation is divided into simple and composite, just as one is divided into simple and composite.
Peri.L8
106. Deinde cum dicit: Est autem simplex enunciatio et cetera, manifestat secundam divisionem enuntiationis, secundum scilicet quod una enuntiatio dividitur in affirmationem et negationem.
He manifests the second division of the enunciation where he says: a simple enunciation is vocal sound signifying that something belongs or does not belong to a subject (17a22), that is, the division of enunciation into affirmation and negation.
Peri.L8
Haec autem divisio primo quidem convenit simplici enuntiationi et ex consequenti convenit compositae; et ideo ad insinuandum rationem praedictae divisionis, dicit quod simplex enuntiatio est vox significativa de eo quod est aliquid, quod pertinet ad affirmationem, vel non est, quod pertinet ad negationem. Et, ne hoc intelligatur solum secundum praesens tempus, subdit: quemadmodum tempora divisa sunt, id est similiter hoc habet locum in aliis temporibus sicut et in praesenti.
This is a division that belongs primarily to the simple enunciation, and consequently to the composite enunciation. Therefore, in order to suggest the basis of the division, he says that a simple enunciation is vocal sound signifying that something belongs to a subject, which pertains to affirmation, or does not belong to a subject, which pertains to negation. And to make it clear that this is not to be understood only of present time, he adds: according to the divisions of time, that is, this holds for other times as well as the present.
Peri.L8
107. Alexander autem existimavit quod Aristoteles hic definiret enuntiationem, et, quia in definitione enuntiationis videtur ponere affirmationem et negationem, volebat hinc accipere quod enuntiatio non esset genus affirmationis et negationis, quia species nunquam ponuntur in definitione generis; id autem quod non univoce praedicatur de multis, quia non significat aliquid unum quod sit commune multis, non potest notificari nisi per illa multa quae significat; et inde est quod, quia unum non dicitur univoce de simplici et composito, sed per prius et posterius, Aristoteles semper in praecedentibus ad notificandum unitatem enuntiationis usus est utroque; quia ergo hic videtur uti affirmatione et negatione ad notificandum enuntiationem, volebat Alexander accipere quod enuntiatio non dicitur de affirmatione et negatione univoce sicut genus de suis speciebus.
Alexander thought that Aristotle was defining the enunciation here and because he seems to put affirmation and negation in the definition he took this to mean that enunciation is not the genus of affirmation and negation, for the species is never posited in the definition of the genus. Now, what is not predicated univocally of many (namely, because it does not signify something one that is common to many) cannot be made known except through the many that are signified. One is not said equivocally of the simple and composite, but primarily and consequently, and hence Aristotle always used both simple and composite in the preceding reasoning to make the unity of the enunciation known. Now, here he seems to use affirmation and negation to make the enunciation known; therefore, Alexander took this to mean that enunciation is not said of affirmation and negation univocally as a genus of its species.
Peri.L8
108. Sed contrarium apparet ex hoc quod Philosophus consequenter utitur nomine enuntiationis ut genere: definiens affirmationem et negationem subdit quod affirmatio est enuntiatio alicuius de aliquo, scilicet per modum compositionis, negatio vero est enuntiatio alicuius ab aliquo, per modum scilicet divisionis; nomine autem aequivoco non consuevimus uti ad notificandum significata eius.
But the contrary appears to be the case, for the Philosopher subsequently uses the name “enunciation” as a genus when, in defining affirmation and negation, he says: affirmation is the enunciation of something about something, that is, by way of composition; negation is the enunciation of something separated from something, that is, by way of division. Moreover, it is not customary to use an equivocal name to make known the things it signifies.
Peri.L8
Et ideo Boethius dicit quod Aristoteles suo modo breviloquio utens, simul usus est et definitione et divisione eius, ita ut quod dicit <de> eo quod est aliquid vel non est, non referatur ad definitionem enuntiationis, sed ad eius divisionem.
For this reason, Boethius says that Aristotle with his customary brevity is using both the definition and its division at once. Therefore, when he says that something belongs or does not belong to a subject, he is not referring to the definition of enunciation but to its division.
Peri.L8
Sed, quia differentiae divisivae generis non cadunt in eius definitione, nec hoc solum quod dicitur vox significativa est sufficiens definitio enuntiationis, melius dici potest, secundum Porphyrium, quod totum est definitio enuntiationis quod dicitur: vox significativa de eo quod est aliquid vel non est, nec tamen ponitur affirmatio vel negatio in definitione enuntiationis, sed virtus affirmationis et negationis, id est significatum ipsius quod est esse vel non esse, quod est naturaliter prius enuntiatione. Affirmationem vero et negationem postea definit per terminos utriusque, cum dicit affirmationem esse enuntiationem alicuius de aliquo et negationem enuntiationem alicuius ab aliquo.
However, since the differences dividing a genus do not fall in its definition, and since significant vocal sound is not a sufficient definition of the enunciation, Porphyry thought it would be better to say that the whole expression, vocal sound signifying that something belongs or does not belong to a subject, is the definition of the enunciation. According to his exposition, this is not affirmation and negation that is posited in the definition, but capacity for affirmation and negation—that is, what the enunciation is a sign of, which is to be or not to be, which is prior in nature to the enunciation. Then, immediately following this, he defines affirmation and negation in terms of themselves when he says that affirmation is the enunciation of something about something; negation the enunciation of something separated from something.
Peri.L8
Sed, quia in definitione generis non debent poni, sicut nec species, ita nec ea quae sunt propria specierum, cum tamen significare esse sit proprium affirmationis, et significare non esse sit proprium negationis, adhuc melius videtur dicendum, secundum Ammonium, quod hic non definitur enuntiatio, sed solum dividitur. Supra enim posita est eius definitio, ubi dictum est quod enuntiatio est oratio in qua est verum vel falsum, in qua quidem definitione nulla mentio facta est nec de affirmatione nec de negatione.
But just as the species should not be stated in the definition of the genus, so neither should the properties of the species. Now, to signify “to be” is the property of the affirmation, and to signify “not to be” the property of the negation. Therefore, Ammonius thought it would be better to say that the enunciation was not defined here, but only divided. For the definition was posited above when it was said that the enunciation is speech in which there is truth or falsity—in which definition no mention is made of either affirmation or negation.
Peri.L8
Est autem considerandum quod hic artificiosissime procedit: dividit enim genus non in species, sed in differentias specificas; non enim dicit quod enuntiatio sit affirmatio vel negatio, sed quod est significativa de eo quod est, quae est differentia specifica affirmationis, vel quod non est, in quo tangitur differentia specifica negationis; et ideo ex his differentiis adiunctis generi constituit definitionem speciei, cum subdit quod affirmatio est enuntiatio alicuius de aliquo, per quod significatur esse, et negatio enuntiatio alicuius ab aliquo, quod significat non esse.
It should be noticed, however, that Aristotle proceeds very skillfully here, for he divides the genus not into species, but into specific differences. He does not say that the enunciation is an affirmation or negation, but that it is vocal sound signifying that something belongs to a subject, which is the specific difference of affirmation, or does not belong to a subject, which is the specific difference of negation. Then, when he adds: affirmation is the enunciation of something about something, which signifies “to be,” and negation is the enunciation of something separated from something, which signifies “not to be,” he establishes the definition of the species by joining the differences to the genus.
Peri.L8
L. 9 (Α.6, 17a26–17a37)The opposition of affirmation and negation absolutelyDe oppositione affirmationis et negationis absolute
17a26. Quoniam autem est enuntiare et quod est non esse, et quod non est esse, et quod est esse, et quod non est non esse. Et circa ea quae sunt extra praesens tempus similiter. Omne contingit quod quis affirmaverit negare, et quod quis negaverit affirmare. Quare manifestum est quoniam omni affirmationi est negatio opposita et omni negationi affirmatio.
17a26. Since it is possible to enunciate that what belongs to a subject does not belong to it and what does not, does, and that what does belong to it, does, and what does not, does not, and to enunciate these in regard to those times outside of the present as well as of the present, it would be possible to deny whatever someone affirms and to affirm what he denies. It is evident, therefore, that there is a negation opposed to every affirmation and an affirmation opposed to every negation.
Peri.L9
17a33. Et sit hoc contradictio, affirmatio et negatio oppositae.
17a33. We will call this opposed affirmation and negation “contradiction.”
Peri.L9
17a34. Dico autem opponi eiusdem de eodem, non autem aequivoce et quaecumque cetera talium determinavimus contra sophisticas importunitates.
17a34. I mean by “opposed” the enunciation of the same thing of the same subject—not equivocally, however, nor in any of the other ways that we have distinguished in reference to the specious difficulties of the sophists.
Peri.L9
109. Quoniam autem est enunciare et cetera. Posita divisione enuntiationis, hic agit de oppositione partium enuntiationis, scilicet affirmationis et negationis.
Since it is possible to enunciate. Having made the division of the enunciation, Aristotle now deals with the opposition of the parts of the enunciation, that is, the opposition of affirmation and negation.
Peri.L9
Et, quia enuntiationem esse dixerat orationem in qua est verum vel falsum, primo ostendit qualiter enuntiationes ad invicem opponantur;
He has already said that the enunciation is speech in which there is truth or falsity. Therefore, he first shows how enunciations are opposed to each other;
Peri.L9
secundo movet quamdam dubitationem circa praedeterminata et solvit, ibi: In his ergo quae sunt et quae facta sunt et cetera.
second, he raises a doubt about some things previously determined and resolves it, at: in enunciations about that which is or has taken place (18a28; [164]).
Peri.L9
Circa primum duo facit: primo determinat qualiter una enuntiatio alteri opponatur; secundo ostendit quod una opponitur uni, ibi: Manifestum est autem et cetera.
He not only shows how one enunciation is opposed to another, but that only one is opposed to one, at: it is evident also that there is one negation of one affirmation (17b38; [154]).
Peri.L9
Prima autem pars dividitur in partes duas: in prima determinat de oppositione affirmationis et negationis absolute;
In showing how one enunciation is opposed to another, he first treats of the opposition of affirmation and negation absolutely;
Peri.L9
in secunda parte, ostendit quomodo huiusmodi oppositio diversificatur ex parte subiecti, ibi: Quoniam autem sunt haec <quidem> rerum universalia et cetera.
second, he shows in what way opposition of this kind is diversified on the part of the subject, at: since some of the things we are concerned with are universal (17a38; [125]).
Peri.L9
Circa primum duo facit:
About the first he does two things.
Peri.L9
primo ostendit quod omni affirmationi est negatio opposita et e converso;
First, he shows that there is a negation opposed to every affirmation and vice versa;
Peri.L9
secundo manifestat oppositionem affirmationis et negationis absolute, ibi: Et sit <hoc> contradictio et cetera.
second, at: we will call this opposed affirmation and negation “contradiction” (17a33; [115]), he explains the opposition of affirmation and negation absolutely.
Peri.L9
110. Circa primum considerandum est quod ad propositum ostendendum Philosophus assumit <duplicem> diversitatem enuntiationis,
In relation to the first point—that there is a negation opposed to every affirmation, and vice versa—the Philosopher assumes a twofold diversity of enunciation.
Peri.L9
quarum una est ex ipsa forma vel modo enuntiandi, secundum quod dictum est quod enuntiatio vel est affirmativa, per quam scilicet enuntiatur aliquid esse; alia autem negativa, per quam significatur aliquid non esse;
The first arises from the very form or mode of enunciating. According to this diversity, enunciation is either affirmative (in which it is enunciated that something is), or negative (in which it is signified that something is not).
Peri.L9
secunda autem diversitas est per comparationem ad rem, ex qua dependet veritas et falsitas intellectus et enuntiationis: cum enim enuntiatur aliquid vel esse vel non esse secundum congruentiam ad rem, est oratio vera, alioquin est oratio falsa.
The second is the diversity that arises by comparison to reality. Truth and falsity of thought and of the enunciation depend upon this comparison, for when it is enunciated that something is or is not, if there is agreement with reality, there is true speech. Otherwise, there is false speech.
Peri.L9
111. Sic igitur quatuor modis potest enuntiatio variari, secundum permixtionem harum duarum divisionum;
The enunciation can therefore be varied in four ways according to a combination of these two divisions.
Peri.L9
uno modo, quia id quod est in re enuntiatur ita esse sicut in re est, puta cum Socrates currit et dicimus Socratem currere;
In the first way, what is in reality is enunciated to be as it is in reality—for example, when Socrates runs, we say, “Socrates is running.”
Peri.L9
alio modo, cum enuntiatur aliquid non esse quod in re non est, quod pertinet ad negationem veram, ut cum dico: ‘Aethiops albus non est’;
In the second way, it is enunciated that something is not that which it is not in reality. This is characteristic of true negation, as when we say, “An Ethiopian is not white.”
Peri.L9
tertio modo, cum enuntiatur aliquid esse quod in re non est, quod pertinet ad affirmationem falsam, ut cum dicitur: ‘Corvus est albus’;
In the third way, it is enunciated that something is what in reality it is not, as when it is said, “The raven is white.”
Peri.L9
quarto modo, cum enuntiatur aliquid non esse quod in re est, ut si dicitur: ‘Nix non est alba’, quae est negatio falsa.
In the fourth way, it is enunciated that something is not what it is in reality, for example, if it is said that “snow is not white,” which is a false negation.
Peri.L9
Philosophus tamen, ut a minoribus ad potiora procedat, praemittit falsas veris, inter quas negativam praemittit affirmativae,
In order to proceed from the weaker to the stronger, the Philosopher puts the false before the true, and among these he states the negative before the affirmative.
Peri.L9
cum dicit quod contingit enuntiare quod est, scilicet in rerum natura, non esse;
He begins, then, with the false negative; it is possible to enunciate, that what is, namely, in reality, is not (17a26).
Peri.L9
secundo autem ponit affirmativam falsam, cum dicit: et quod non est, scilicet in rerum natura, esse;
Second, he posits the false affirmative: and that what is not, namely, in reality, is.
Peri.L9
tertio autem ponit affirmativam veram, quae opponitur negativae falsae quam primo posuit, cum dicit: et quod est, scilicet in rerum natura, <esse>;
Third, he posits the true affirmative, which is opposed to the false negative he gave first: and that what is, namely, in reality, is.
Peri.L9
quarto vero ponit negativam veram, quae opponitur secundae, scilicet affirmativae falsae, cum dicit: et quod non est, scilicet in rerum natura, non esse.
Fourth, he posits the true negative, which is opposed to the false affirmative: and that what is not, namely, in reality, is not.
Peri.L9
112. Non est autem intelligendum quod per hoc quod dixit: quod est et quod non est sit referendum ad solam existentiam vel non existentiam subiecti, sed ad hoc quod res significata per praedicatum insit vel non insit rei significatae per subiectum; nam, cum dico: ‘Corvus est albus’, significatur quod non est esse, quamvis ipse corvus sit res existens.
In saying what is and what is not, Aristotle is not referring only to the existence or nonexistence of a subject. What he is saying is that the reality signified by the predicate is in or is not in the reality signified by the subject. For what is signified in saying, “The raven is white,” is that what is not, is, although the raven itself is an existing thing.
Peri.L9
113. Et, sicut istae quatuor differentiae enuntiationum inveniuntur in propositionibus in quibus ponitur verbum praesentis temporis, ita etiam inveniuntur in enuntiationibus in quibus ponuntur verba praeteriti vel futuri temporis: supra enim dixit quod enuntiationem necesse est constare ex verbo vel casu. Et hoc est quod subdit: et similiter contingit, scilicet variari diversimode enuntiationem circa ea quae sunt extra praesens tempus, id est circa praeterita vel futura quae sunt quodam modo extrinseca respectu praesentis, quia praesens est medium praeteriti et futuri.
These four differences of enunciations are found in propositions in which there is a verb of present time, and they are also found in enunciations in which there are verbs of past or future time. He said earlier that every enunciative speech must contain a verb or a mode of the verb. Here he makes this point in relation to the four differences of enunciations: similarly it is possible to enunciate these, that is, that the enunciation be varied in diverse ways, in regard to those times outside of the present, that is, with respect to the past or future, which are in a certain way extrinsic in respect to the present, since the present is between the past and the future.
Peri.L9
114. Et quia ita est, sequitur quod contingit omne quod quis affirmaverit negare et omne quod quis negaverit affirmare. Quod quidem manifestum est ex praemissis: non enim potest affirmari nisi vel quod est in rerum natura secundum aliquod trium temporum, vel quod non est, et hoc totum contingit negare; unde manifestum est quod omne quod affirmatur potest negari et e converso.
Since there are these four differences of enunciation in past and future time as well as in present time, it is possible to deny everything that is affirmed and to affirm everything that is denied. This is evident from the premises, for it is only possible to affirm either that which is in reality according to past, present, or future time, or that which is not. It is also possible to deny all of this. It is clear, then, that everything that is affirmed can be denied, and vice versa.
Peri.L9
Et, quia affirmatio et negatio secundum se opposita sunt, utpote ex opposito condivisae, consequens est quod quaelibet affirmatio habeat negationem sibi oppositam et e converso. Cuius contrarium illo solo modo posset contingere, si aliqua affirmatio affirmaret aliquid quod negatio negare non posset.
Now, since affirmation and negation are in itself opposed, that is, in an opposition of contradiction, it follows that any affirmation would have a negation opposed to it, and conversely. The contrary of this could happen only if an affirmation could affirm something that the negation could not deny.
Peri.L9
115. Deinde cum dicit: Et sit hoc contradictio et cetera, manifestat quae sit absoluta oppositio affirmationis et negationis.
When he says: we will call this opposed affirmation and negation “contradiction” (17a33), he explains what absolute opposition of affirmation and negation is.
Peri.L9
Et primo manifestat eam per nomen;
He does this first through the name;
Peri.L9
secundo per definitionem, ibi: Dico autem opponi et cetera.
second, through the definition where he says: I mean by “opposed” (17a34; [116]).
Peri.L9
116. Dicit ergo primo quod, cum cuilibet affirmationi opponatur negatio et e converso, oppositioni huiusmodi imponatur hoc nomen quod dicatur ‘contradictio’. Per hoc enim quod dicit: sit hoc contradictio, datur intelligi quod ipse nomen contradictionis imposuit oppositioni affirmationis et negationis, ut Ammonius dicit.
He says that “contradiction” is the name imposed for the kind of opposition in which a negation is opposed to an affirmation (and conversely). By saying: we will call this “contradiction”, we are given to understand—as Ammonius points out—that he has himself imposed the name “contradiction” for the opposition of affirmation and negation.
Peri.L9
Deinde cum dicit: Dico autem opponi et cetera, definit contradictionem.
Then he defines contradiction when he says: I mean by “opposed” (17a34).
Peri.L9
Quia vero, ut dictum est, contradictio est oppositio affirmationis et negationis, illa requiruntur ad contradictionem quae sunt necessaria ad oppositionem affirmationis et negationis; oportet autem opposita esse circa idem, et, quia enuntiatio constituitur ex subiecto et praedicato, requiritur ad contradictionem primo quidem quod affirmatio et negatio sint eiusdem praedicati: si enim dicatur: ‘Plato currit, Plato non disputat’, non est contradictio;
Since contradiction is the opposition of affirmation and negation, as he has said, whatever is required for the opposition of affirmation and negation is required for contradiction. Now, opposites must be about the same thing, and since the enunciation is made up of a subject and predicate, the first requirement for contradiction is affirmation and negation of the same predicate. For if we say, “Plato runs, and Plato does not discuss,” there is no contradiction.
Peri.L9
secundo requiritur quod sint de eodem subiecto: si enim dicatur: ‘Socrates currit, Plato non currit, non est contradictio;
The second is that the affirmation and negation be of the same subject, for if we say, “Socrates runs, and Plato does not run,” there is no contradiction.
Peri.L9
tertio requiritur quod identitas praedicati et subiecti non solum sit secundum nomen, sed simul sit secundum rem et nomen: nam si non sit idem nomen, manifestum est quod non est una et eadem enuntiatio; similiter etiam ad hoc quod sit enuntiatio una, requiritur identitas <rei>: dictum est enim supra quod una enuntiatio est quae unum significat; et ideo subdit: non autem aequivoce, id est non sufficit identitas nominis cum diversitate rei, quae facit aequivocationem.
The third requirement is identity of subject and predicate not only according to name but according to the thing and the name at once. Clearly, if the same name is not used, there is not one and the same enunciation; similarly, there must be identity of the thing, for as was said above, the enunciation is one when it signifies one thing said of one thing. This is why he adds: not equivocally, however, for identity of name with diversity of the thing—which is equivocation—is not sufficient for contradiction.
Peri.L9
117. Sunt vero et quaedam alia in contradictione observanda ad hoc quod tollatur omnis diversitas, praeter eam quae est affirmationis et negationis: non enim esset oppositio si non omnino idem negaret negatio quod affirmatio affirmavit.
There are also certain other things that must be observed with respect to contradiction so that all diversity is destroyed except the diversity of affirmation and negation, for if the negation does not deny in every way the same thing that the affirmation affirms, there will not be opposition.
Peri.L9
Haec autem diversitas potest secundum quatuor considerari:
Inquiry can be made about this diversity in respect to four things.
Peri.L9
uno quidem modo secundum diversas partes subiecti: non enim est contradictio si dicatur quod aethiops est albus secundum dentem et non est albus secundum pedem;
First, are there diverse parts of the subject? For if we say that an Ethiopian is white as to teeth and not white as to foot, there is no contradiction.
Peri.L9
secundo si sit diversus modus ex parte praedicati: non enim est contradictio si dicatur: ‘Socrates currit tarde et non movetur velociter’, vel si dicatur: ‘Ovum est animal in potentia et non est animal in actu';
Second, is there a diverse mode on the part of the predicate? For there is no contradiction if we say, “Socrates runs slowly,” and “Socrates is not moving swiftly,” or “An egg is an animal in potency,” and “An egg is not an animal in act.”
Peri.L9
tertio si sit diversitas ex parte mensurae, puta loci vel temporis: non enim est contradictio si dicatur: ‘Pluit in Gallia, in Italia non pluit’, aut ‘Pluit heri, hodie non pluit’;
Third, is there diversity on the part of measure, such as of place or time? For there is no contradiction if we say, “It is raining in Gaul,” and “It is not raining in Italy,” or “It rained yesterday,” and “It did not rain today.”
Peri.L9
quarto si sit diversitas ex habitudine ad aliquid extrinsecum, puta si dicatur decem homines esse multos ut ad domum, non autem ut ad forum.
Fourth, is there diversity from a relationship to something extrinsic? For example, when we say, “Ten men are many in respect to a house, but not in respect to a market.”
Peri.L9
Et haec omnia designat cum subdit: et quaecumque cetera talium determinavimus, id est determinare consuevimus, in disputationibus contra sophisticas importunitates, id est contra importunas et litigiosas oppositiones sophistarum, de quibus plenius facit mentionem in I Elenchorum.
Aristotle designates all of these when he adds: nor in any of the other ways that we have distinguished; in other words, it is usual to determine in disputations against the specious difficulties of the sophists, that is, against the fallacious and quarrelsome objections of the sophists, which he mentions more fully in Sophistical Refutations 1.5, 166b28–167a36.
Peri.L9
L. 10 (Α.7, 17a38–17b16)The proposition’s division on the part of the subject; affirmation and negation in universal and indefinite propositionsDe divisione propositionum ex parte subiecti: deque oppositione affirmationis et negationis in propositionibus universal
17a38. Quoniam autem rerum haec quidem sunt universalia, illa vero singularia. Dico autem universale quod de pluribus natum est praedicari, singulare vero quod non; ut ‘homo’ quidem universale, ‘Plato’ vero eorum quae sunt singularia.
17a38. Since some of the things we are concerned with are universal and others singular—by “universal,” I mean that which is of such a nature as to be predicated of many, and by “singular,” that which is not (for example “man” is universal, “Plato” singular)—
Peri.L10
17b1. Necesse est autem enuntiare quoniam inest aliquid aut non, aliquotiens quidem eorum alicui quae sunt universalia, aliquotiens vero eorum quae sunt singularia.
17b1. we have to enunciate either of a universal or of a singular that something belongs or does not belong to it.
Peri.L10
17b3. Si ergo universaliter enuntiet in universali quoniam est aut non est, erunt contrariae enuntiationes; dico autem in universali enuntiationem universalem, ut ‘Omnis homo est albus—Nullus homo est albus’.
17b3. If, then, it is universally enunciated of a universal that something belongs or does not belong to it, the enunciations will be contraries. By “universally enunciated of a universal,” I mean such enunciations as “every man is white” or “no man is white.”
Peri.L10
17b6. Quando autem in universalibus non universaliter, non sunt contrariae, quae autem significantur est esse contraria.
17b6. On the other hand, when the enunciations are of a universal but not universally enunciated, they are not contraries, although it is possible for the things signified to be contraries.
Peri.L10
17b8. Dico autem non universaliter enuntiare in his quae sunt universalia, ut, ‘Est albus homo—Non est albus homo’.
17b8. I mean by “enunciated of a universal but not universally” such enunciations as “man is white” or “man is not white.”
Peri.L10
17b10. Cum enim universale sit homo, non universaliter utitur enuntiatione; ‘omnis’ namque non ‘universale’ est, sed ‘quoniam universaliter’ consignificat.
17b10. For, while “man” is a universal, it is not used as universal in the enunciation, for “every” does not signify the universal but signifies that it is taken “universally.”
Peri.L10
17b12. In eo vero quod universale praedicatur, id quod est universale praedicari universaliter non est verum. Nulla enim affirmatio erit, in qua de universali praedicato universaliter praedicetur, ut ‘Omnis homo est omne animal’.
17b12. But as regards the predicate, the universal universally predicated is not true; for no affirmation will be true in which a universal predicate is predicated universally, such as “every man is every animal.”
Peri.L10
118. Quoniam autem rerum haec quidem sunt universalia et cetera. Quia Philosophus dixerat oppositionem affirmationis et negationis esse contradictionem, quae est eiusdem et de eodem, intendit consequenter distinguere diversas oppositiones affirmationis et negationis, ut cognoscatur quae sit vera contradictio.
Since some of the things we are concerned with. The Philosopher has just said that contradiction is the opposition of the affirmation and negation of the same thing of the same subject. Following upon this, he distinguishes the diverse oppositions of affirmation and negation, the purpose being to know what true contradiction is.
Peri.L10
Et circa hoc duo facit:
And here he does two things:
Peri.L10
primo praemittit quamdam divisionem enuntiationum necessariam ad praedictam differentiam oppositionum assignandam;
first, he states a division of enunciation which is necessary in order to assign the difference of these oppositions;
Peri.L10
secundo manifestat propositum, ibi: Si ergo universaliter et cetera.
second, he begins to manifest the different oppositions where he says: if, then, it is universally enunciated of a universal (17b3; [128]).
Peri.L10
Praemittit autem divisionem enuntiationum quae sumitur secundum differentiam subiecti; unde circa primum duo facit:
The division he gives is taken from the difference of the subject; therefore, about the first he does two things:
Peri.L10
primo dividit subiectum enuntiationum;
first, he divides the subject of enunciations;
Peri.L10
secundo concludit divisionem enuntiationum, ibi: Necesse est autem enunciare et cetera.
second, he concludes with the division of enunciation, at: we have to enunciate either of a universal or of a singular (17b1; [125]).
Peri.L10
119. Subiectum autem enuntiationis est nomen vel aliquid sumptum loco nominis; nomen autem est vox significativa simplicis intellectus, qui est similitudo rei; et ideo subiectum enuntiationis distinguit secundum divisionem rerum.
Now, the subject of an enunciation is a name or something taken in place of a name. A name is a vocal sound significant by convention of simple thought, which, in turn, is a likeness of the thing.
Peri.L10
Et dicit quod rerum quaedam sunt universalia, quaedam vero singularia.
Hence, Aristotle distinguishes the subject of enunciation by a division of things. He says that of things, some are universals, others singulars (17a38).
Peri.L10
Manifestat autem membra divisionis dupliciter:
He then explains the members of this division in two ways.
Peri.L10
primo quidem per definitionem, quod universale est quod natum est de pluribus praedicari, singulare vero quod non est natum praedicari de pluribus, sed de uno solo;
First, he defines them, saying that the universal is that which is of such a nature as to be predicated of many, and that the singular is that which is not to be predicated of many, but of one alone.
Peri.L10
secundo per exemplum, cum subdit quod ‘homo’ est universale, ‘Plato’ vero singulare.
Then he manifests them by example when he says that “man” is universal, “Plato” singular.
Peri.L10
120. Accidit autem dubitatio circa hanc divisionem quia, sicut Philosophus probat in VII Metaphysicae, universale non est aliquid extra in rebus subsistens; et in Praedicamentis dicitur quod secundae substantiae non sunt nisi in primis, quae sunt singulares; non ergo videtur esse conveniens divisio rerum in universalia et singularia, quia nullae res videntur esse universales, sed omnes res sunt singulares.
There is a difficulty about this division, for the Philosopher proves in Metaphysics1 that the universal is not something existing outside of the thing; and in the Categories,2 he says that second substances are only in first substances, that is, singulars. Therefore, the division of things into universals and singulars does not seem to be consistent, since according to him there are no things that are universal; on the contrary, all things are singular.
Peri.L10
121. Dicendum est autem quod hic dividuntur res secundum quod significantur per nomina quae subiiciuntur in enuntiationibus; dictum est autem supra quod nomina non significant res nisi mediante intellectu, et ideo oportet quod divisio ista rerum accipiatur secundum quod res cadunt in intellectu. Ea vero quae sunt coniuncta in rebus, intellectus potest distinguere, quando unum eorum non cadit in ratione alterius. In qualibet autem re singulari est considerare aliquid quod est proprium illi rei in quantum est haec res, sicut Socrati vel Platoni in quantum est hic homo;
The things divided here, however, are things as signified by names—which names are subjects of enunciations. Now, Aristotle has already said that names signify things only through the mediation of the intellect; therefore, this division must be taken as a division of things as apprehended by the intellect. Now, in fact, whatever is joined together in things can be distinguished by the intellect when one of them does not belong to the notion of the other. In any singular thing, we can consider what is proper to the thing insofar as it is this thing—for instance, what is proper to Socrates or to Plato insofar as he is this man.
Peri.L10
aliquid autem est considerare in eo, in quo convenit cum aliis quibusdam rebus, sicut quod Socrates est homo vel animal aut rationalis aut risibilis aut albus. Quando igitur res denominatur ab eo quod convenit illi soli rei in quantum est haec res, huiusmodi nomen dicitur significare aliquid singulare; quando autem denominatur res ab eo quod est commune sibi et multis aliis, nomen huiusmodi dicitur significare universale, quia scilicet nomen significat naturam vel dispositionem aliquam quae est communis multis. Quia igitur hanc divisionem dedit de rebus non absolute secundum quod existunt extra animam, sed secundum quod referuntur ad intellectum, non definivit universale et singulare secundum aliquid quod pertinet ad rem, puta ut diceret quod universale est extra singularia, quod pertineret ad opiniones Platonicas, sed per actum animae intellectivae, qui est praedicari de multis vel de uno solo.
We can also consider that in which it agrees with certain other things, as that Socrates is an animal, or man, or rational, or risible, or white. Accordingly, when a thing is denominated from what belongs only to this thing insofar as it is this thing, the name is said to signify a singular. When a thing is denominated from what is common to it and to many others, the name is said to signify a universal since it signifies a nature or some disposition which is common to many. Immediately after giving this division of things, then—not of things absolutely as they are outside of the soul, but as they are referred to the intellect—Aristotle defines the universal and the singular through the act of the intellective soul as that which is such as to be predicated of many or of only one, and not according to anything that pertains to the thing (that is, as if he were affirming such a universal outside of the soul, an opinion relating to Plato’s teaching).
Peri.L10
122. Est autem considerandum quod intellectus apprehendit rem intellectam secundum propriam rationem seu definitionem; unde et in III De anima dicitur quod obiectum proprium intellectus est quod quid est. Contingit autem quandoque quod propria ratio alicuius formae intellectae non repugnat ei quod est esse in pluribus, sed hoc impeditur ab aliquo alio, sive illud sit aliquid accidentaliter adveniens, puta si, omnibus hominibus morientibus, unus solus remaneret, sive sit propter conditionem materiae, sicut est unus tantum sol, non quia repugnet rationi solari esse in pluribus secundum considerationem formae ipsius, sed quia non est alia materia susceptiva talis formae. Et ideo non dixit quod universale est quod praedicatur de pluribus, sed quod aptum natum est de pluribus praedicari.
There is a further point we should consider in relation to this portion of the text. The intellect apprehends the thing—understood according to the thing’s essence or definition. This is the reason Aristotle says1 that the proper object of the intellect is what the thing essentially is. Now, sometimes the proper nature of some understood form is not repugnant to being in many but is impeded by something else, either by something occurring accidentally (for instance, if all men but one were to die), or because of the condition of matter. The sun, for instance, is only one not because it is repugnant to the notion of the sun to be in many according to the condition of its form, but because there is no other matter capable of receiving such a form. This is the reason Aristotle did not say that the universal is that which is predicated of many, but that which is of such a nature as to be predicated of many.
Peri.L10
123. Cum autem omnis forma quae nata est recipi in materia, quantum est de se, communicabilis sit multis materiis, dupliciter potest contingere quod id quod significatur per nomen non sit aptum natum de pluribus praedicari:
Now, since every form which is so constituted as to be received in matter is communicable to many matters, there are two ways in which what is signified by a name may not be of such a nature as to be predicated of many:
Peri.L10
uno modo, quia nomen significat formam secundum quod est determinata ad hanc materiam, sicut hoc nomen ‘Socrates’ vel ‘Plato’, quod significat naturam humanam prout est in hac materia;
in one way, because a name signifies a form as terminated in this matter (for example, as in the name “Socrates” or “Plato,” which signifies human nature as it is in this matter);
Peri.L10
alio modo secundum quod nomen significat formam quae non est nata in materia recipi, unde oportet quod per se remaneat una et singularis, sicut albedo, si esset forma non existens in materia, esset una sola, unde esset singularis; et propter hoc dicit Philosophus in VII Metaphysicae quod, si essent species rerum separatae sicut Plato posuit, essent individua quaedam.
in another way, because a name signifies a form which is not constituted to be received in matter and consequently must remain in itself one and singular. Whiteness, for example, would be only one if it were a form not existing in matter, and consequently singular. This is the reason the Philosopher says that if there were separated species of things, as Plato held, they would be individuals.1
Peri.L10
124. Potest autem obiici quod hoc nomen ‘Socrates’ vel ‘Plato’ natum est de pluribus praedicari, quia nihil prohibet esse multos qui vocentur hoc nomine.
It could be objected that the name “Socrates” or “Plato” is of such a kind as to be predicated of many, since there is nothing to prevent their being applied to many.
Peri.L10
Sed ad hoc patet responsio, si attendantur verba Aristotelis: ipse enim non divisit nomina in universale et particulare, sed res; et ideo intelligendum est quod universale dicitur quando non solum nomen potest de pluribus praedicari, sed id quod significatur per nomen est natum in pluribus inveniri; hoc autem non contingit in praedictis nominibus: nam nomen Socratis vel Platonis significat naturam humanam secundum quod est in hac materia; si vero hoc nomen imponatur alteri homini, significabit naturam humanam in alia materia, et sic eius erit alia significatio, unde non erit universale, sed aequivocum.
The response to this objection is evident if we consider Aristotle’s words. Notice that he divides things into universal and particular, not names. It should be understood from this that what is said to be universal not only has a name that can be predicated of many, but that what is signified by the name is of such a nature as to be found in many. Now, this is not the case in the above-mentioned names, for the name of “Socrates” or “Plato” signifies human nature as it is in this matter. If one of these names is imposed on another man, it will signify human nature in other matter, and it will be a different signification. Consequently, it will be equivocal, not universal.
Peri.L10
125. Deinde cum dicit: Necesse est autem et cetera, concludit ex praedictis divisionem enuntiationis.
When he says: we have to enunciate either of a universal or of a singular (17b1), he infers the division of the enunciation.
Peri.L10
Quia enim semper enuntiatur aliquid de aliqua re, rerum autem quaedam sunt universalia, quaedam singularia, necesse est quod quandoque enuntietur aliquid inesse vel non inesse alicui universali, quandoque vero alicui singulari. Et est suspensiva constructio usque huc, ut sit sensus: Quoniam autem rerum et cetera, necesse est enuntiare et cetera.
Since something is always enunciated of something, and of things some are universals and some singulars, it follows that sometimes it will be enunciated that something belongs or does not belong to something universal, sometimes to something singular. The construction of the sentence was interrupted by the explanation of universal and singular, but now we can see the meaning: since some of the things we are concerned with are universal and others singulars . . . we have to enunciate either of a universal or of a singular that something belongs or does not belong to it.
Peri.L10
126. Est autem considerandum quod de universali aliquid enuntiatur quatuor modis.
In relation to the point being made here, we have to consider the four ways in which something is enunciated of the universal.
Peri.L10
Nam universale potest uno modo considerari quasi separatum a singularibus, sive sicut per se subsistens, ut Plato posuit, sive, secundum Aristotelis sententiam, secundum esse quod habet in intellectu; et sic potest ei aliquid attribui dupliciter.
On the one hand, the universal can be considered as though separated from singulars, whether subsisting in itself (as Plato held), or according to the being it has in the intellect (as Aristotle held). Considered thus, something can be attributed to it in two ways.
Peri.L10
Quandoque enim attribuitur ei sic considerato aliquid quod pertinet ad solam actionem intellectus, ut si dicatur quod homo est praedicabile de multis aut universale aut genus aut species; huiusmodi enim intentiones format intellectus attribuens eas naturae intellectae, secundum quod comparat ipsam ad res quae sunt extra animam.
Sometimes we attribute something to it which pertains only to the operation of the intellect, such as when we say man (whether the universal, the genus, or the species) is predicable of many. For the intellect forms intentions of this kind and attributes them to the nature understood according as it compares the nature to the things outside of the mind.
Peri.L10
Quandoque vero attribuitur aliquid universali sic considerato, quod scilicet apprehenditur ab intellectu ut unum, tamen id quod attribuitur ei non pertinet ad actum intellectus, sed ad esse quod habet natura apprehensa in rebus quae sunt extra animam, puta si dicatur quod homo est dignissima creaturarum: hoc enim convenit naturae humanae etiam secundum quod est in singularibus, nam quilibet homo singularis est dignior omnibus irrationalibus creaturis; sed tamen omnes homines singulares non sunt unus extra animam, sed solum in acceptione intellectus; et per hunc modum attribuitur sibi praedicatum, scilicet ut uni rei.
But sometimes we attribute something to the universal thus considered (that is, as it is apprehended by the intellect as one) which does not belong to the act of the intellect but to the being that the nature apprehended has in things outside of the soul, such as when we say, “Man is the noblest of creatures.” For this truly belongs to human nature as it is in singulars, since any single man is more noble than all irrational creatures; yet all singular men are not one man outside of the mind, but only in the apprehension of the intellect, and the predicate is attributed to it in this way (that is, as to one thing).
Peri.L10
Alio autem modo attribuitur aliquid universali prout est in ipsis singularibus; et hoc dupliciter.
On the other hand, we attribute something to the universal as in singulars in another way, and this is twofold.
Peri.L10
Quandoque quidem ratione ipsius naturae universalis, puta cum attribuitur ei aliquid quod ad essentiam eius pertinet vel consequitur principia essentialia, ut cum dico: ‘Homo est animal’, vel: ‘Homo est risibile’.
Sometimes it is in view of the universal nature itself, such as when we attribute something to it that belongs to its essence, or follows upon the essential principles, as in “Man is an animal,” or “Man is risible.”
Peri.L10
Quandoque autem attribuitur ei aliquid ratione singularis in quo invenitur, puta cum attribuitur ei aliquod accidens individuale, ut cum dicitur, ‘Homo ambulat’.
Sometimes it is in view of the singular in which the universal is found; for instance, when we attribute something to the universal that pertains to the individual, as in “Man walks.”
Peri.L10
Singulari autem attribuitur aliquid tripliciter:
Moreover, something is attributed to the singular in three ways:
Peri.L10
uno modo secundum quod cadit in apprehensione, ut cum dicitur: ‘Socrates est singulare’, vel ‘praedicabile de uno solo’;
in one way, as it is subject to the intellect, as when we say, “Socrates is a singular,” or “predicable of only one”;
Peri.L10
quandoque autem ratione naturae communis, ut cum dicitur: ‘Socrates est animal’;
in another way, by reason of the common nature, as when we say, “Socrates is an animal”;
Peri.L10
quandoque autem ratione sui ipsius, ut cum dicitur: ‘Socrates ambulat’.
in the third way, by reason of itself, as when we say, “Socrates is walking.”
Peri.L10
Et totidem etiam modis negationes variantur, quia omne quod contingit affirmare, contingit negare, ut supra dictum est.
The negations are varied in the same number of ways, since everything that can be affirmed can also be denied, as was said above.
Peri.L10
127. Est autem haec tertia divisio enuntiationis quam Philosophus ponit.
This is the third division the Philosopher has given of the enunciation.
Peri.L10
Prima namque fuit quod enuntiationum quaedam est una simpliciter, quaedam coniunctione una, quae quidem est divisio analogi in ea de quibus praedicatur secundum prius et posterius: sic enim unum dividitur in simplex et compositum.
The first was the division of the enunciation into one simply and one by conjunction. This is an analogous division into those things of which one is predicated primarily and consequently, for one is divided according to the prior and posterior into simple and composite.
Peri.L10
Alia vero fuit divisio enuntiationis in affirmationem et negationem, quae quidem est generis in species, quia sumitur secundum differentiam praedicati, ad quod fertur negatio, praedicatum autem est pars formalis enuntiationis; et ideo huiusmodi divisio dicitur pertinere ad qualitatem enuntiationis, qualitatem, inquam, essentialem, secundum quod differentia significat quale quid.
The second was the division of enunciation into affirmation and negation. This is a division of genus into species, for it is taken from the difference of the predicate to which a negation is added. The predicate is the formal part of the enunciation, and hence such a division is said to pertain to the quality of the enunciation. By “quality,” I mean essential quality, for in this case the difference signifies the quality of the essence.
Peri.L10
Tertia autem est haec divisio, quae sumitur secundum differentiam subiecti, quod praedicatur de pluribus vel de uno solo; et ideo dicitur pertinere ad quantitatem enuntiationis, nam et quantitas consequitur materiam.
The third division is based upon the difference of the subject as predicated of many or of only one, and is therefore a division that pertains to the quantity of the enunciation, for quantity follows upon matter.
Peri.L10
128. Deinde cum dicit: Si ergo universaliter et cetera, ostendit quomodo enuntiationes diversimode opponantur secundum diversitatem subiecti.
Aristotle shows next how enunciations are opposed in diverse ways according to the diversity of the subject, at: if, then, it is universally enunciated of a universal (17b3).
Peri.L10
Et circa hoc duo facit:
And here he does two things:
Peri.L10
primo distinguit diversos modos oppositionum in ipsis enuntiationibus;
first, he distinguishes the diverse modes of opposition in enunciations;
Peri.L10
secundo ostendit quomodo diversae oppositiones diversimode se habent ad verum et falsum, ibi: Quocirca has quidem impossibile et cetera.
second, he shows how these diverse oppositions are related in different ways to truth and falsity, at: hence in the case of the latter it is impossible that both be at once true (17b23; [148]).
Peri.L10
129. Circa primum considerandum est quod, cum universale possit considerari in abstractione a singularibus vel secundum quod est in ipsis singularibus, et secundum hoc diversimode ei aliquid potest attribui, ut supra dictum est. Ad designandum diversos modos attributionis adinventae sunt quaedam dictiones quae possunt dici determinationes seu signa quibus designatur quod aliquid de universali hoc vel illo modo praedicetur.
First, then, he distinguishes the diverse modes of opposition. Since these depend upon a diversity in the subject, we must first consider the latter diversity. Now, the universal can be considered either in abstraction from singulars or as it is in singulars, and by reason of this something is attributed in diverse modes to the universal, as we have already said. To designate diverse modes of attribution, certain words have been conceived which may be called determinations or signs, and which designate that something is predicated in this or that mode.
Peri.L10
Sed, quia non est communiter ab hominibus apprehensum quod universalia extra singularia subsistant, ideo communis usus loquendi non habet aliquam dictionem ad designandum illum modum praedicandi prout aliquid dicitur de eo in abstractione a singularibus; sed Plato, qui posuit universalia extra singularia subsistere, adinvenit quasdam determinationes quibus designaretur quomodo aliquid attribuitur universali prout est extra singularia, et vocabat universale separatim subsistens extra singularia, quantum ad speciem hominis ‘per se hominem’, vel ‘ipsum hominem’; et similiter in aliis universalibus.
But first we should note that since it is not commonly apprehended by all men that universals subsist outside of singulars, there is no word in common speech to designate the mode of predicating in which something is thus said of a universal in abstraction from singulars. Plato, who held that universals subsist outside of singulars, did, however, invent certain determinations to designate the way in which something is attributed to the universal as it is outside of singulars. With respect to the species “man,” he called the separated universal subsisting outside of singulars “man in itself” or “man itself,” and he designated other such universals in like manner.
Peri.L10
Sed universale secundum quod est in singularibus cadit in communi apprehensione hominum, et ideo adinventae sunt quaedam dictiones ad designandum modum attribuendi universali sic accepto, ut supra dictum est.
However, the universal as it is in singulars does fall within the common apprehension of men, and accordingly certain words have been conceived to signify the mode of attributing something to the universal taken in this way.
Peri.L10
Qui secundum praedicta duplex est.
As was said above, this happens in two ways.
Peri.L10
130. Quandoque enim attribuitur aliquid universali ratione ipsius naturae universalis, et ideo hoc dicitur praedicari de eo universaliter, quia scilicet convenit ei secundum totam multitudinem in qua invenitur; et ad hoc designandum in affirmativis praedicationibus adinventa est haec dictio ‘omnis’, quae designat quod praedicatum attribuatur universali subiecto quantum ad totum id quod sub eo continetur; in negativis autem praedicationibus ad idem inventa est haec dictio ‘nullus’, per quam scilicet significatur quod praedicatum removetur a subiecto universali secundum totum id quod continetur sub eo; unde ‘nullus’ dicitur quasi ‘non ullus’, et in Graeco dicitur ‘oudeis’, id est ‘neque unus’, quia scilicet nec unum solum est accipere sub subiecto universali a quo praedicatum non removeatur.
Sometimes, something is attributed to the universal in view of the universal nature itself; for this reason, it is said to be predicated of the universal universally—that is, it belongs to the universal according to the whole multitude in which it is found. The word “every” has been devised to designate this in affirmative predications. It designates that the predicate is attributed to the universal subject with respect to the whole of what is contained under the subject. In negative predications, the word “no” has been devised to signify that the predicate is removed from the universal subject according to the whole of what is contained under it. Hence, saying “nullus,” or “none,” in Latin is like saying “non ullus,” or “not any.” In Greek, ουδεις, “none,” is like ουδε εις, “not one,” for not a single one is understood under the universal subject from which the predicate is not removed.
Peri.L10
Quandoque vero attribuitur aliquid universali vel removetur ab eo ratione particularis, et ad hoc designandum, in affirmativis quidem adinventa est haec dictio ‘aliquis’ vel ‘quidam’, per quam designatur quod praedicatum attribuitur universali subiecto ratione ipsius particularis (sed, quia non determinate significat formam alicuius singularis, sub quadam indeterminatione singulare designat, unde et dicitur ‘individuum vagum’); in negativis vero non est aliqua una dictio posita, sed possumus accipere ‘non omnis’, ut, sicut ‘nullus’ universaliter removet, eo quod significat quasi diceretur ‘non ullus’, id est ‘non aliquis’, ita etiam ‘non omnis’ particulariter removeat, in quantum excludit universalem affirmationem.
Sometimes, something is either attributed to or removed from the universal in view of the particular. To designate this in affirmative enunciations, the words “some” or “a certain one” has been devised. We designate by this that the predicate is attributed to the universal subject by reason of the particular. “Some” or “a certain one,” however, do not signify the form of any singular determinately; rather, they designate the singular under a certain indetermination. The singular so designated is therefore called the vague individual. In negative enunciations, there is no designated word, but “not all” can be used. Just as “no,” then, removes universally because it signifies the same thing as if we were to say “not any” (that is, “not some”), so also “not all” removes particularly inasmuch as it excludes universal affirmation.
Peri.L10
131. Sic igitur tria sunt genera affirmationum in quibus de universali aliquid praedicatur:
There are, therefore, three kinds of affirmations in which something is predicated of a universal:
Peri.L10
una quidem est in qua de universali aliquid praedicatur universaliter, ut cum dico: ‘Omnis homo est animal’;
in one, something is predicated of the universal universally, as in “every man is an animal”;
Peri.L10
alia vero in qua de universali praedicatur aliquid particulariter, ut cum dicitur: ‘Quidam homo est albus’;
in another, something is predicated of the universal particularly, as in “some man is white”;
Peri.L10
tertia vero est in qua aliquid de universali praedicatur absque determinatione universalitatis vel particularitatis, unde huiusmodi enuntiatio solet vocari indefinita.
in the third, something is predicated of the universal without a determination of universality or particularity. Enunciations of this kind are customarily called “indefinite.”
Peri.L10
Totidem autem sunt negationes oppositae.
There are the same number of opposed negations.
Peri.L10
132. De singulari autem, quamvis aliquid diversa ratione praedicetur, ut supra dictum est, tamen totum refertur ad singularitatem ipsius, quia etiam natura universalis in ipso singulari individuatur; et ideo nihil differt, quantum ad rationem singularitatis, utrum praedicetur de eo aliquid ratione universalis naturae, ut cum dico: ‘Socrates est animal’, vel quod conveniat ei ratione sui singularis.
In the case of the singular, although something is predicated of it in a different respect (as was said above), nevertheless, the whole is referred to its singularity because the universal nature is individuated in the singular. Therefore, it makes no difference as far as the nature of singularity is concerned whether something is predicated of the singular by reason of the universal nature, as in “Socrates is a man,” or belongs to it by reason of its singularity.
Peri.L10
133. Si igitur praedictis tribus enuntiationibus singularis addatur, erunt quatuor enuntiationem modi ad quantitatem ipsius pertinentes, scilicet universalis, particularis, indefinita et singularis.
If we add the singular to the three already mentioned, there will be four modes of enunciation pertaining to quantity: universal, particular, indefinite, and singular.
Peri.L10
134. Sic igitur secundum has differentias Aristoteles assignat diversas oppositiones enuntiationum ad invicem.
Aristotle assigns the diverse oppositions of enunciations according to these differences.
Peri.L10
Et primo secundum differentiam universalium ad indefinitas; secundo secundum differentiam universalium ad particulares, ibi: Opponi autem affirmationem et cetera.
The first opposition is based on the difference of universals and indefinites; the second on the difference of universals and particulars, the latter being treated where he says: affirmation is opposed to negation in the way I call contradictory (17b16; [143]).
Peri.L10
Circa primum tria facit:
About the first he does three things:
Peri.L10
primo agit de oppositione propositionum universalium ad invicem;
first, he treats of the opposition of universal propositions to each other;
Peri.L10
secundo de oppositione indefinitarum, ibi: Quando autem in universalibus et cetera;
second, the opposition of indefinite enunciations, at: when the enunciations are of a universal (17b6; [136]);
Peri.L10
tertio excludit dubitationem, ibi: In eo vero quod universale et cetera.
third, he excludes a doubt, at: in the predicate, however, the universal (17b12; [140]).
Peri.L10
135. Dicit ergo primo quod, si aliquis enuntiet de universali subiecto universaliter, id est secundum continentiam suae universalitatis, quoniam est, id est affirmative, aut non est, id est negative, erunt contrariae enuntiationes, ut si dicatur: ‘Omnis homo est albus—Nullus homo est albus’.
He says first (17b3), then, that if someone enunciates universally of a universal subject (namely, according to the content of its universality) that it is (that is, affirmatively), or is not (that is, negatively), these enunciations will be contrary; as when we say, “every man is white—no man is white.”
Peri.L10
Huius autem ratio est quia contraria dicuntur quae maxime distant: non enim aliquid dicitur nigrum ex hoc solo quod non est album, sed super hoc quod est non esse album, quod significat communiter remotionem albi, addit nigrum extremam distantiam ab albo. Sic igitur id quod affirmatur per hanc enuntiationem: ‘Omnis homo est albus’, removetur per hanc negationem: ‘Non omnis homo est albus’: oportet enim quod negatio removeat modum quo praedicatum dicitur de subiecto, quem designat haec dictio ‘omnis’; sed super <hanc> remotionem addit haec enuntiatio: ‘Nullus homo est albus’, totalem remotionem, quae est extrema distantia a primo, quod pertinet ad rationem contrarietatis; et ideo convenienter hanc oppositionem dixit esse contrarietatem.
And the reason is that the things that are most distant from each other are said to be contraries. For a thing is not said to be black only because it is not white, but because over and beyond “not being white”—which signifies the remotion of white commonly—is added black, the extreme in distance from white. What is affirmed by the enunciation, “every man is white,” then, is removed by the negation, “not every man is white.” The negation, therefore, removes the mode in which the predicate is said of the subject which the word “every” designates. But over and beyond this remotion, the enunciation, “no man is white,” which is most distant from “every man is white,” adds total remotion, and this belongs to the notion of contrariety. He therefore appropriately calls this opposition contrariety.
Peri.L10
136. Deinde cum dicit: Quando autem in universalibus et cetera, ostendit qualis sit oppositio affirmationis et negationis in indefinitis.
When he says: on the other hand, when the enunciations are of a universal (17b6), he shows what kind of opposition there is between affirmation and negation in indefinite enunciations.
Peri.L10
Et primo proponit quod intendit;
First, he states the point;
Peri.L10
secundo manifestat propositum per exempla, ibi: Dico autem non universaliter et cetera;
second, he manifests it by an example, at: I mean by “enunciated of a universal but not universally” (17b8).
Peri.L10
tertio assignat rationem manifestationis, ibi: Cum enim universale sit homo et cetera.
Finally, he gives the reason for this when he says: for while “man” is a universal, it is not used as a universal (17b10).
Peri.L10
Dicit ergo primo quod quando de universalibus subiectis affirmatur et negatur aliquid, non tamen universaliter, non sunt contrariae enuntiationes, sed illa quae significantur contingit esse contraria.
He says first, then, that when something is affirmed or denied of a universal subject, but not universally, the enunciations are not contrary but the things that are signified may be contraries.
Peri.L10
Deinde cum dicit: Dico autem non universaliter et cetera, manifestat quod dixerat per exempla.
He clarifies this with examples, at: I mean by “enunciated of a universal but not universally” (17b8).
Peri.L10
Ubi considerandum est quod non dixerat: quando in universalibus particulariter, sed: non universaliter: non enim intelligit hic de particularibus enuntiationibus, sed solum de indefinitis. Et hoc manifestat per exempla quae ponit, dicens fieri in universalibus subiectis non universalem enuntiationem, cum dicitur: ‘Homo est albus—Homo non est albus’.
Note in relation to this that what he said just before this was when . . . of universals but not universally enunciated (17b6), and not, when . . . of universals particularly, because he only intends to speak of indefinite enunciations, not of particulars. He manifests this by the examples he gives. When we say, “man is white,” and, “man is not white,” the universal subjects do not make them universal enunciations.
Peri.L10
Et rationem huius expositionis ostendit consequenter per hoc quod ‘homo’, qui subiicitur, est universale, sed tamen praedicatum non universaliter enuntiatur de eo, quia non apponitur haec dictio ‘omnis’, quae non significat ipsum universale, sed significat modum universalitatis, prout scilicet praedicatum universaliter dicitur de subiecto, et ideo additum subiecto universali significat simul quod universaliter aliquid de eo dicatur.
He gives as the reason for this, that although man, which stands as the subject, is universal, the predicate is not predicated of it universally because the word “every” is not added, which does not itself signify the universal, but the mode of universality—namely, that the predicate is said universally of the subject. Therefore, when “every” is added to the universal subject, it always signifies that something is said of it universally.
Peri.L10
Tota autem haec expositio ad hoc solum refertur quod dixerat: Quando in universalibus non universaliter.
This whole exposition relates to what he had been saying: on the other hand, when the enunciations are of a universal but not universally enunciated, they are not contraries (17b6).
Peri.L10
137. Sed hoc quod additur: non sunt contrariae, quae autem significantur est esse contraria, non est expositum, quamvis obscuritatem contineat, et ideo a diversis diversimode exponitur. Quidam enim hoc referre voluerunt ad contrarietatem veritatis et falsitatis, quae competit huiusmodi enuntiationibus: contingit enim has quandoque simul esse veras: ‘Homo est albus—Homo non est albus’, et sic non sunt contrariae, quia contraria mutuo se tollunt; contingit tamen quandoque unam earum esse veram et alteram falsam, ut cum dicitur: ‘Homo est animal—Homo non est animal’, et sic, ratione significati, videntur habere quamdam contrarietatem.
Immediately after this, he adds: although it is possible for the things signified to be contraries (17b6), and although this is obscure, he does not explain it. It has therefore been interpreted in different ways. Some related it to the contrariety of truth and falsity proper to enunciations of this kind. For such enunciations may be simultaneously true, such as “man is white” and “man is not white,” and thus not be contraries, for contraries mutually destroy each other. On the other hand, one may be true and the other false, such as “man is an animal” and “man is not an animal,” and thus by reason of what is signified seem to have a certain kind of contrariety.
Peri.L10
Sed hoc non videtur ad propositum pertinere,
But this does not seem to be related to what Aristotle has said:
Peri.L10
tum quia Philosophus nondum hic loquitur de veritate et falsitate enuntiationum,
first, because the Philosopher has not yet taken up the point of truth and falsity of enunciations;
Peri.L10
tum etiam quia hoc ipsum posset et de particularibus enuntiationibus dici.
second, because this very thing can also be said of particular enunciations.
Peri.L10
138. Alii vero, sequentes Porphyrium, referunt hoc ad contrarietatem praedicati: contingit enim quandoque quod praedicatum negatur de subiecto propter hoc quod inest ei contrarium, sicut si dicatur: ‘Homo non est albus’, quia est niger; et sic id quod significatur per hoc quod dicitur: ‘non est albus’, potest esse contrarium. Non tamen semper: removetur enim aliquid a subiecto etiam si contrarium non insit, sed aliquid medium inter contraria, ut cum dicitur: ‘Aliquis non est albus’, quia est pallidus; vel quia inest ei privatio actus vel habitus seu potentiae, ut cum dicitur: ‘Aliquis non est videns’, quia est carens potentia visiva aut habens impedimentum ne videat, vel etiam quia non est natus videre, puta si dicatur quod lapis non videt. Sic igitur illa quae significantur contingit esse contraria, sed tamen ipsae enuntiationes non sunt contrariae, quia, ut in fine huius libri dicetur, non sunt contrariae opiniones quae sunt de contrariis, sicut opinio quod aliquid sit bonum et illa quae est quod aliquid sit malum.
Others, following Porphyry, relate this to the contrariety of the predicate. For sometimes the predicate may be denied of the subject because of the presence of the contrary in it, as when we say, “Man is not white,” because he is black. Thus it could be the contrary that is signified by “is not white.” This is not always the case, however, for we remove something from a subject even when it is not a contrary that is present in it but some mean between contraries, as in saying, “Someone is not white” because he is pale; or when there is a privation of act or habit or potency, as in saying, “Someone is non-seeing” because he lacks the power of sight or has an impediment so that he cannot see, or even because something is not of such a nature as to see, as in saying, “A stone does not see.” It is therefore possible for the things signified to be contraries, but the enunciations themselves not to be; for, as is said near the end of this book, opinions that are about contraries are not contrary (for example, an opinion that something is good and an opinion that something is evil).
Peri.L10
139. Sed nec hoc videtur ad propositum Aristotelis pertinere, quia non agit hic de contrarietate rerum vel opinionum, sed de contrarietate enuntiationum.
This does not seem to relate to what Aristotle has proposed either, for he is not treating here of contrariety of things or opinions, but of contrariety of enunciations. For this reason it seems better here to follow the exposition of Alexander.
Peri.L10
Et ideo magis videtur hic sequenda expositio Alexandri, secundum quam dicendum est quod <in> indefinitis enuntiationibus non determinatur utrum praedicatum attribuatur subiecto universaliter, quod faceret contrarietatem enuntiationum, aut particulariter, quod non faceret contrarietatem enuntiationum, et ideo huiusmodi enuntiationes indefinitae non sunt contrariae secundum modum quo proferuntur, contingit tamen, ratione significati, eas habere contrarietatem, puta cum attribuitur aliquid universali ratione naturae universalis, quamvis non apponatur signum universale, ut cum dicitur: ‘Homo est animal—Homo non est animal’, quia hae enuntiationes eamdem habent vim, ratione significati, ac si diceretur: ‘Omnis homo est animal—Nullus homo est animal’.
According to his exposition, in indefinite enunciations it is not determined whether the predicate is attributed to the subject universally (which would constitute contrariety of enunciations), or particularly (which would not constitute contrariety of enunciations). Accordingly, enunciations of this kind are not contrary in mode of expression. However, sometimes they have contrariety by reason of what is signified, that is, when something is attributed to a universal in virtue of the universal nature, although the universal sign is not added, as in “man is an animal” and “man is not an animal,” for in virtue of what is signified these enunciations have the same force as “every man is an animal” and “no man is an animal.”
Peri.L10
140. Deinde cum dicit: In eo vero quod universale et cetera, removet quiddam quod posset esse dubium.
When he says: but as regards the predicate, the universal universally predicated is not true (17b12), he precludes a certain difficulty.
Peri.L10
Quia enim posuerat quamdam diversitatem in oppositione enuntiationum ex hoc quod universale sumitur ex parte subiecti universaliter vel non universaliter, posset aliquis credere quod similis diversitas nasceretur ex parte praedicati, ex hoc scilicet quod universale praedicari posset vel universaliter vel non universaliter. Et ideo ad hoc excludendum subdit quod in eo quod praedicatur aliquod universale, non est verum quod praedicetur universale universaliter.
He has already stated that there is a diversity in the opposition of enunciations because of the universal being taken either universally or not universally on the part of the subject. Someone might think, as a consequence, that a similar diversity would arise on the part of the predicate—that is, that the universal could be predicated both universally and not universally. To exclude this, he says that in the case in which a universal is predicated it is not true that the universal is predicated universally.
Peri.L10
Cuius quidem ratio duplex esse potest.
There are two reasons for this.
Peri.L10
Una quidem quia talis modus praedicandi videtur repugnare praedicato secundum propriam rationem quam habet in enuntiatione. Dictum est enim supra quod praedicatum est quasi pars formalis enuntiationis, subiectum autem est pars materialis ipsius; cum autem aliquod universale profertur universaliter, ipsum universale sumitur secundum habitudinem quam habet ad singularia quae sub se continet; sicut et, quando universale profertur particulariter, sumitur secundum habitudinem quam habet ad aliquod sub se contentorum; et sic utrumque pertinet ad materialem determinationem universalis; et ideo neque signum universale neque particulare convenienter additur praedicato, sed magis subiecto; convenientius enim dicitur: ‘Nullus homo est asinus’, quam: ‘Omnis homo est nullus asinus’; et similiter etiam convenientius dicitur: ‘Aliquis homo est albus’, quam: ‘Homo est aliquod album’. Invenitur tamen quandoque a philosophis signum particulare appositum praedicato ad insinuandum quod praedicatum est in plus quam subiectum, et hoc praecipue cum, habito genere, investigant differentias completivas speciei, sicut dicitur in II De anima quod anima est actus quidam.
The first is that such a mode of predicating seems to be repugnant to the predicate in relation to its status in the enunciation; for, as has been said, the predicate is a quasi-formal part of the enunciation, while the subject is a material part of it. Now, when a universal is asserted universally, the universal itself is taken according to the relationship it has to the singulars contained under it, and when it is asserted particularly, the universal is taken according to the relationship it has to some one of what is contained under it. Thus both pertain to the material determination of the universal. This is why it is not appropriate to add either the universal or particular sign to the predicate, but rather to the subject; for it is more appropriate to say, “No man is an ass” than “Every man is no ass”; likewise, it is more proper to say, “Some man is white” than “Man is some white.” However, sometimes philosophers put the particular sign next to the predicate to indicate that the predicate is in more than the subject, and this especially when they have a genus in mind and are investigating the differences which complete the species. There is an instance of this in On the Soul 2.1, 412a22, where Aristotle says that the soul is a certain act.
Peri.L10
Alia vero ratio potest accipi ex parte veritatis enuntiationis; et ista specialiter habet locum in affirmativis, quae falsae essent si praedicatum universaliter praedicaretur. Et ideo manifestans id quod posuerat, subiungit quod nulla affirmatio erit, in qua, scilicet universali, praedicetur universaliter de universali praedicato, id est in qua universali praedicato utatur ad universaliter praedicandum, ut si diceretur: ‘Omnis homo est omne animal’. Oporteret enim, secundum praedicta, quod hoc praedicatum ‘animal’ secundum singula quae sub ipso continentur praedicaretur de singulis quae continentur sub homine, et hoc non potest esse verum neque si praedicatum sit in plus neque si praedicatum sit convertibile: oporteret quod quilibet unus homo esset omnia animalia aut omnia risibilia, quod repugnant rationi singularis quod accipitur sub universali.
The other reason is related to the truth of enunciations. This has a special place in affirmations, which would be false if the predicate were predicated universally. Hence to manifest what he has stated, he adds, for there is no affirmation in which, that is, truly, a universal predicate will be predicated universally, that is, in which a universal predicate is used to predicate universally—for example, “every man is every animal.” If this could be done, the predicate “animal,” according to the singulars contained under it, would have to be predicated of the singulars contained under “man.” But such predication could not be true, whether the predicate is in more than the subject or is convertible with the subject, for then any one man would have to be all animals or all risible beings, which is repugnant to the notion of the singular, which is taken under the universal.
Peri.L10
141. Nec est instantia si dicatur quod haec est vera: ‘Omnis homo est omnis disciplinae susceptivus’: ‘disciplina’ enim non praedicatur de homine, sed ‘susceptivum disciplinae’; repugnaret autem veritati si diceretur: ‘Omnis homo est omne susceptivum disciplinae’.
The truth of the enunciation, “every man is susceptible of every discipline” is not an instance that can be used as an objection to this position, for it is not “discipline” that is predicated of man, but “susceptible of discipline.” It would be repugnant to truth if it were said that “every man is everything susceptible of discipline.”
Peri.L10
142. Signum autem universale negativum vel particulare affirmativum, etsi convenientius ponantur ex parte subiecti, non tamen repugnat veritati si ponantur ex parte praedicati: contingit enim huiusmodi enuntiationes in aliqua materia esse veras; haec enim est vera: ‘Omnis homo nullus lapis est’, et similiter haec est vera: ‘Omnis homo aliquod animal est’. Sed haec: ‘Omnis homo omne animal est’, in quacumque materia proferatur, falsa est.
On the other hand, although the negative universal sign or the particular affirmative sign are more appropriately posited on the part of the subject, it is not repugnant to truth if they are posited on the part of the predicate, for such enunciations may be true in some matter. The enunciation, “every man is no stone,” for example, is true, and so is “every man is some animal.” But the enunciation, “every man is every animal,” in whatever matter it occurs, is false.
Peri.L10
Sunt autem quaedam aliae tales enuntiationes semper falsae, sicut ista: ‘Aliquis homo omne animal est’, quae habet eamdem causam falsitatis cum hac: ‘Omnis homo omne animal est’; et si quae aliae similes sunt semper falsae, in omnibus est eadem ratio; et ideo per hoc quod Philosophus reprobavit istam: ‘Omnis homo omne animal est’, dedit intelligere omnes consimiles esse improbandas.
There are other enunciations of this kind that are always false, such as “some man is every animal” (which is false for the same reason as “every man is every animal” is false). And if there are any others like these, they are always false; and the reason is the same in every case. And, therefore, in rejecting the enunciation, “every man is every animal,” the Philosopher meant it to be understood that all similar enunciations are to be rejected.
Peri.L10
L. 11 (Α.7, 17b16–17b37)The opposition of universal and particular enunciations; the relation of affirmation and negation to truth and falsityDe oppositione inter propositiones universales et particulares deque modo quo se habent affirmatio et negatio oppositae
17b16. Opponi autem affirmationem negationi dico contradictorie quae universaliter significat ei quae non universaliter, ut: ‘Omnis homo est albus—Non omnis homo est albus’; ‘Quidam homo est albus—Nullus homo est albus’.
17b16. Affirmation is opposed to negation in the way I call contradictory when the one signifying universally is opposed to the same one not signifying universally, as in “every man is white” and “not every man is white,” “no man is white” and “some man is white.”
Peri.L11
17b20. Contrarie vero universalem affirmationem et universalem negationem, ut ‘Omnis homo est iustus—Nullus homo est iustus’.
17b20. They are opposed contrarily when the universal affirmation is opposed to the universal negation, as in “every man is just” and “no man is just.”
Peri.L11
17b23. Quocirca has quidem impossibile est simul veras esse, his vero oppositas contingit in eodem, ut: ‘Non omnis homo albus est’, et ‘Quidam homo albus est’.
17b23. Hence in the case of the latter, it is impossible that both be at once true, but it is possible for the contradictories of these contraries to be at once true with respect to the same subject, as in “not every man is white” and “some man is white.”
Peri.L11
17b26. Quaecumque igitur contradictiones universalium sunt universaliter, necesse est alteram esse veram, alteram falsam, et quaecumque in singularibus sunt, ut: ‘Socrates albus est—Socrates albus non est’.
17b26. Whenever there are contradictions with respect to universals signifying universally, one must be true, the other false. This is also the case when there are contradictions with respect to singulars, as in “Socrates is white” and “Socrates is not white.”
Peri.L11
17b29. Quaecumque autem in universalibus non universaliter, non semper haec vera est, illa vero falsa: simul enim verum est dicere quoniam est homo albus et non est homo albus, et est homo probus et non est homo probus.
17b29. But when the contradictions are of universals not signifying universally, one is not always true and the other false, for it is at once true to say that man is white and man is not white, and man is beautiful and man is not beautiful.
Peri.L11
17b33. Si enim turpis, non est probus; et est homo pulcher et non est homo pulcher; si enim foedus, non pulcher. Et si fit aliquid, non est.
17b33. For if he is ugly, he is not beautiful; and if he is becoming something, he is not yet it.
Peri.L11
17b34. Videbitur autem subito inconveniens esse, idcirco quoniam videtur ‘Non est homo albus’ simul etiam significare quoniam nemo albus est; hoc autem neque idem significat neque simul necessario.
17b34. At first sight this might seem paradoxical, because “man is not white” seems to signify the same thing as “no man is white”; but it neither signifies this, nor are they at once true necessarily.
Peri.L11
143. Opponi autem affirmationem et cetera. Postquam Philosophus determinavit de oppositione enuntiationum comparando universales enuntiationes ad indefinitas, hic determinat de oppositione enuntiationum comparando universales ad particulares.
Affirmation is opposed to negation. Now that he has determined the opposition of enunciations by comparing universal enunciations with indefinite enunciations, Aristotle determines the opposition of enunciations by comparing universals to particulars.
Peri.L11
Circa quod considerandum est quod potest duplex oppositio in his notari:
It should be noted that there is a twofold opposition in these enunciations:
Peri.L11
una quidem universalis ad particularem, et hanc primo tangit;
first, one of universal to particular;
Peri.L11
alia vero universalis ad universalem, et hanc tangit secundo, ibi: Contrariae vero et cetera.
second, the opposition of universal to universal, which he takes up at: they are opposed contrarily (17b20; [147]).
Peri.L11
144. Particularis vero affirmativa et particularis negativa non habent proprie loquendo oppositionem, quia oppositio attenditur circa idem subiectum; subiectum autem particularis enuntiationis est universale particulariter sumptum, non pro aliquo determinato singulari, sed indeterminate pro quocumque; et ideo, cum de universali particulariter sumpto aliquid affirmatur vel negatur, ipse modus enuntiandi non habet quod affirmatio et negatio sint de eodem, quod requiritur ad oppositionem affirmationis et negationis, secundum praemissa.
The particular affirmative and particular negative do not have opposition properly speaking, because opposition is concerned with the same subject. But the subject of a particular enunciation is the universal taken particularly, not for a determinate singular but indeterminately for any singular. For this reason, when something is affirmed or denied of the universal particularly taken, the mode of enunciating is not such that the affirmation and negation are of the same thing. Hence what is required for the opposition of affirmation and negation is lacking.
Peri.L11
145. Dicit ergo primo quod enuntiatio quae universale significat, scilicet universaliter, opponitur contradictorie ei quae non significat universaliter, sed particulariter, si una earum sit affirmativa et altera negativa, sive universalis sit affirmativa et particularis negativa <sive e converso>; ut cum dicitur: ‘Omnis homo est albus—Non omnis homo est albus’: hoc enim quod dico ‘Non omnis’ ponitur loco signi particularis negativi, unde aequipollet ei quae est: ‘Quidam homo non est albus’; sicut ‘nullus’, quod idem significat ac si diceretur ‘non ullus’ vel ‘non quidam’, est signum universale negativum; unde hae duae: ‘Quidam homo est albus’ quae est particularis affirmativa, et ‘Nullus homo est albus’, quae est universalis negativa, sunt contradictoriae.
First (17b16), he says that the enunciation that signifies the universal (that is, universally) is opposed contradictorily to the one that does not signify universally but particularly, if one of them is affirmative and the other negative (whether the universal is affirmative and the particular negative or conversely). For example, “every man is white” or “not every man is white.” For “not every” is used in place of the particular negative sign; consequently, “not every man is white” is equivalent to “some man is not white.” In a parallel way, “no,” which signifies the same thing as “not any” or “not some,” is the universal negative sign. Consequently, the two enunciations, “some man is white,” which is the particular affirmative, and “no man is white,” which is the universal negative, are contradictories.
Peri.L11
146. Cuius ratio est quia contradictio consistit in sola remotione affirmationis per negationem; universalis autem affirmativa removetur per solam negationem particularis, nec aliquid aliud ex necessitate ad hoc exigitur; particularis autem affirmativa removeri non potest nisi per universalem negativam, quia iam dictum est quod particularis negativa non proprie opponitur particulari affirmativae. Unde relinquitur quod universali affirmativae contradictorie opponatur particularis negativa et particulari affirmativae universalis negativa.
The reason for this is that contradiction consists in the mere removal of the affirmation by a negation. Now, the universal affirmative is removed merely by the negation of the particular, and nothing else is required of necessity. But the particular affirmative can only be removed by the universal negative because, as has already been said, the particular negative is not properly opposed to the particular affirmative. Consequently, the particular negative is opposed contradictorily to the universal affirmative and the universal negative to the particular affirmative.
Peri.L11
147. Deinde cum dicit: Contrariae vero et cetera, tangit oppositionem universalium enuntiationum.
When he says: they are opposed contrarily (17b20), he touches on the opposition of universal enunciations.
Peri.L11
Et dicit quod universalis affirmativa et universalis negativa sunt contrariae, sicut: ‘Omnis homo est iustus—Nullus homo est iustus’, quia scilicet universalis negativa non solum removet affirmativam universalem, sed etiam designat extremam distantiam, in quantum negat totum quod affirmatio ponit, et hoc pertinet ad rationem contrarietatis; et ideo particularis affirmativa et negativa se habent sicut medium inter contraria.
The universal affirmative and universal negative, he says, are contraries, as in “every man is just—no man is just.” For the universal negative not only removes the universal affirmative, but also designates an extreme of distance between them inasmuch as it denies the whole that the affirmation posits, and this belongs to the notion of contrariety. The particular affirmative and particular negative, for this reason, are related as a mean between contraries.
Peri.L11
148. Deinde cum dicit: Quocirca has et cetera, ostendit quomodo se habeant affirmatio et negatio oppositae ad verum et falsum.
He shows how the opposed affirmation and negation are related to truth and falsity when he says: hence in the case of the latter it is impossible that both be at once true (17b23).
Peri.L11
Et primo quantum ad contrarias;
First, he shows this in regard to contraries;
Peri.L11
secundo quantum ad contradictorias, ibi: Quaecumque igitur contradictiones et cetera;
second, in regard to contradictories, at: whenever there are contradictions with respect to universal signifying universally (17b26; [149]);
Peri.L11
tertio quantum ad ea quae videntur contradictoria et non sunt, ibi: Quaecumque autem in universalibus et cetera.
third, in regard to those that seem contradictory but are not, at: but when the contradictions are of universals not signifying universally (17b29; [150]).
Peri.L11
Dicit ergo primo quod, quia universalis affirmativa et universalis negativa sunt contrariae, impossibile est quod sint simul <verae>: contraria enim mutuo se expellunt. Sed particulares, quae contradictorie opponuntur universalibus contrariis, possunt simul verificari in eodem, sicut: ‘Non omnis homo est albus’, quae contradictorie opponitur huic: ‘Omnis homo est albus’, et ‘Quidam homo est albus’, quae contradictorie opponitur huic: ‘Nullus homo est albus’. Et huius etiam simile invenitur in contrarietate rerum: nam album et nigrum numquam possunt esse simul in eodem, sed remotiones albi et nigri simul possunt esse: potest enim aliquid esse neque album neque nigrum, sicut patet in eo quod est pallidum. Et similiter contrariae enuntiationes non possunt esse simul verae, sed earum contradictoriae, quibus removentur, simul possunt esse verae.
First, he says that because the universal affirmative and universal negative are contraries, it is impossible for them to be simultaneously true, for contraries mutually remove each other. However, the particular enunciations that are contradictorily opposed to the universal contraries can be verified at the same time in the same thing, such as “not every man is white” (which is opposed contradictorily to “every man is white”) and “some man is white” (which is opposed contradictorily to “no man is white”). A parallel to this is found in the contrariety of things, for white and black can never be in the same thing at the same time, but the remotion of white and black can be in the same thing at the same time, for a thing may be neither white nor black, as is evident in something yellow. In a similar way, contrary enunciations cannot be at once true, but their contradictories, by which they are removed, can be true simultaneously.
Peri.L11
149. Deinde cum dicit: Quaecumque igitur contradictiones et cetera, ostendit qualiter se habeat veritas et falsitas in contradictoriis.
Then, when he says: whenever there are contradictions (17b26), he shows the relationship between truth and falsity in contradictories.
Peri.L11
Circa quod considerandum est quod, sicut praedictum est, in contradictione negatio non plus facit nisi quod removet affirmationem. Quod quidem contingit dupliciter:
Here he shows how truth and falsity are related in contradictories. As was said above, in contradictories the negation does no more than remove the affirmation, and this in two ways:
Peri.L11
uno modo quando una earum est universalis et alia particularis, ut supra dictum est;
in one way when one of them is universal, the other particular, as was said above;
Peri.L11
alio modo quando utraque est singularis,
in another way when each is singular.
Peri.L11
quia tunc negatio ex necessitate refertur ad idem (quod non contingit in particularibus et indefinitis), nec potest se in plus extendere nisi ut removeat affirmationem; et ideo singularis negativa semper contradictoria est singulari affirmativae, supposita identitate praedicati et subiecti.
In the case of the singular, the negation is necessarily referred to the same thing—which is not the case in particulars and indefinites—and cannot extend to more than removing the affirmation. Accordingly, the singular affirmative is always contradictory to the singular negative, supposing the identity of subject and predicate.
Peri.L11
Et ideo dicit quod, sive accipiantur contradictiones universalium universaliter, sive singularium enuntiationum, necesse est semper quod una sit vera et altera falsa. Neque enim contingit simul esse verum esse et non esse, neque simul esse falsum, quia verum nihil aliud est quam cum dicitur esse quod est vel non esse quod non est, et falsum nihil aliud esse videtur quam dicere esse quod non est vel non esse quod est, ut patet ex V Metaphysicae.
Aristotle says, therefore, that whether we take the contradiction of universals universally,1 or the contradiction of singular enunciations, one of them must always be true and the other false. It is not possible for them to be at once true or at once false because to be true is nothing other than to say of that which is that it is, or of that which is not that it is not; to be false, to say of that which is not that it is, or of that which is that it is not, as is evident in Metaphysics 5.7, 1011b25.
Peri.L11
150. Deinde cum dicit: Quaecumque autem in universalibus et cetera, ostendit qualiter se habeat veritas et falsitas in his quae videntur esse contradictoria, sed non sunt.
When he says: but when the contradictions are of universals not signifying universally (17b29), he shows how truth and falsity are related to enunciations that seem to be contradictory, but are not.
Peri.L11
Et circa hoc tria facit:
And about this he does three things:
Peri.L11
primo proponit quod intendit;
first, he proposes how they are related;
Peri.L11
secundo probat propositum, ibi: Si enim turpis, non est probus et cetera;
second, he proves it, at: for if he is ugly, he is not beautiful (17b33; [152]);
Peri.L11
tertio excludit id quod posset facere dubitationem, ibi: Videbitur autem subito et cetera.
third, he excludes a possible difficulty, at: at first sight this might seem paradoxical (17b34; [153]).
Peri.L11
Circa primum considerandum est quod affirmatio et negatio in indefinitis propositionibus videntur contradictorie opponi propter hoc quod est unum subiectum non determinatum per signum particulare, et ideo videtur affirmatio et negatio esse de eodem.
With respect to the first point, we should note that affirmation and negation in indefinite propositions seem to be opposed contradictorily because there is one subject in both of them and it is not determined by a particular sign. Hence, the affirmation and negation seem to be about the same thing.
Peri.L11
Sed ad hoc removendum Philosophus dicit quod quaecumque affirmative et negative dicuntur de universalibus non universaliter sumptis, non semper oportet quod unum sit verum et aliud falsum, sed possunt simul esse vera; simul enim est verum dicere quod ‘Homo est albus’ et ‘Homo non est albus’, et quod ‘Homo est probus’, et quod ‘Homo non est probus’.
To exclude this, the Philosopher says that in the case of affirmative and negative enunciations of universals not taken universally, one need not always be true and the other false, but they can be at once true. For it is true to say both that “man is white” and that “man is not white,” and that “man is honorable” and “man is not honorable.”
Peri.L11
151. In quo quidem, ut Ammonius refert, aliqui Aristoteli contradixerunt, ponentes quia indefinita negativa semper sit accipienda pro universali negativa.
On this point, as Ammonius reports, some men have taken a position contradictory to Aristotle’s, maintaining that the indefinite negative is always to be taken for the universal negative.
Peri.L11
Et hoc astruebant primo quidem tali ratione, quia indefinita, cum sit indeterminata, se habet in ratione materiae; materia autem secundum se considerata magis trahitur ad id quod indignius est; dignior autem est universalis affirmativa quam particularis affirmativa, et ideo indefinitam affirmativam dicunt esse sumendam pro particulari affirmativa; sed negativam universalem, quod totum destruit, dicunt esse indigniorem particulari negativa, quae destruit partem, sicut universalis corruptio peior est quam particularis; et ideo dicunt quod indefinita negativa sumenda est pro universali negativa.
They argued their position in the following way. The indefinite, since it is indeterminate, partakes of the nature of matter; but matter considered in itself is regarded as what is less worthy. Now, the universal affirmative is more worthy than the particular affirmative, and therefore they said that the indefinite affirmative was to be taken for the particular affirmative. But, they said, the universal negative, which destroys the whole, is less worthy than the particular negative, which destroys the part (just as universal corruption is worse than particular corruption); therefore, they said that the indefinite negative was to be taken for the universal negative.
Peri.L11
Ad quod etiam inducunt quod philosophi, et etiam ipse Aristoteles utitur indefinitis negativis pro universalibus, sicut cum dicitur in libro Physicorum quod non est motus praeter res, et in libro De anima quod non est sensus praeter quinque.
They went on to say in support of their position that philosophers, and even Aristotle himself, used indefinite negatives as universals. Thus, in the book Physics1 Aristotle says that there is not movement apart from the thing; and in the book On the Soul,2 he says that there are not more than five senses.
Peri.L11
Sed istae rationes non cogunt.
However, these reasons are not cogent.
Peri.L11
Quod enim primo dicitur quod materia secundum se sumpta sumitur pro peiori, est verum secundum sententiam Platonis, qui non distinguebat privationem a materia, non autem est verum secundum Aristotelem, qui dicit in I Physicorum quod malum et turpe et alia huiusmodi ad defectum pertinentia non dicuntur de materia nisi per accidens; et ideo non oportet quod indefinita semper stet pro peiori.
What they say about matter—that considered in itself it is taken for what is less worthy—is true according to the opinion of Plato, who did not distinguish privation from matter; however, it is not true according to Aristotle, who says1 that evil, ugly, and other things of this kind pertaining to defect are said of matter only accidentally. Therefore, the indefinite need not stand always for the more ignoble.
Peri.L11
Dato etiam quod indefinitam necesse sit sumi pro peiori, non oportet quod sumatur pro universali negativa, quia, sicut in genere affirmationum universalis affirmativa est potior, utpote continens particularem affirmativam, ita etiam in genere negationum universalis negativa potior est; oportet autem in unoquoque genere considerari <id> quod est potius in genere illo, non autem id quod est potius simpliciter.
Even supposing that the indefinite must be taken for the less worthy, it ought not to be taken for the universal negative, for just as the universal affirmative is more powerful than the particular in the genus of affirmation, since it contains the particular affirmative, so also the universal negative is more powerful in the genus of negations. Now, in each genus one must consider what is more powerful in that genus, not what is more powerful simply.
Peri.L11
Ulterius, etiam dato quod particularis negativa esset potior omnibus modis, non tamen adhuc sequeretur: non enim ideo indefinita affirmativa sumitur pro particulari affirmativa quia sit indignior, sed quia de universali potest aliquid affirmari ratione sui ipsius vel ratione partis sub eo contentae, unde sufficit ad veritatem eius quod praedicatum uni parti conveniat, quod designatur per signum particulare, et ideo veritas particularis affirmativae sufficit ad veritatem indefinitae affirmativae. Et, simili ratione, veritas particularis negativae sufficit ad veritatem indefinitae negativae, quia similiter contingit aliquid negari de universali vel ratione sui ipsius vel ratione suae partis.
Further, if we took the position that the particular negative is more powerful than all other modes, the reasoning still would not follow, for the indefinite affirmative is not taken for the particular affirmative because it is less worthy, but because something can be affirmed of the universal by reason of itself, or by reason of the part contained under it. Thus, it suffices for the truth of the particular affirmative that the predicate belongs to one part (which is designated by the particular sign); for this reason the truth of the particular affirmative suffices for the truth of the indefinite affirmative. For a similar reason, the truth of the particular negative suffices for the truth of the indefinite negative, because in like manner, something can be denied of a universal either by reason of itself, or by reason of its part.
Peri.L11
Utuntur autem quandoque philosophi indefinitis negativis pro universalibus in his quae per se removentur ab universalibus, sicut et utuntur indefinitis affirmativis pro universalibus in his quae per se de universalibus praedicantur.
It should be noted that philosophers sometimes use indefinite negatives for universals in the case of things that are in itself removed from universals, and they use indefinite affirmatives for universals in the case of things that are in themselves predicated of universals.
Peri.L11
152. Deinde cum dicit: Si enim turpis et cetera, probat propositum per id quod est ab omnibus concessum.
When he says: for if he is ugly, he is not beautiful (17b33), he proves what he has proposed by something conceded by everyone.
Peri.L11
Omnes enim concedunt quod indefinita affirmativa verificatur si particularis sit vera. Contingit autem accipi duas affirmativas indefinitas quarum una includit negationem alterius, puta cum sunt opposita praedicata.
Everyone concedes that the indefinite affirmative is true if the particular affirmative is true. We may take two indefinite affirmatives, one of which includes the negation of the other, as (for example) when they have opposed predicates.
Peri.L11
Quae quidem oppositio potest attendi dupliciter.
Now, this opposition can happen in two ways.
Peri.L11
Uno modo secundum perfectam contrarietatem, sicut turpis, id est inhonestus, opponitur probo, id est honesto, et foedus, id est deformis secundum corpus, opponitur pulchro. Sed per quam rationem ista affirmativa est vera: ‘Homo est probus’, quodam homine probo existente, per eamdem rationem ista est vera: ‘Homo est turpis’, quodam homine turpi existente. Sunt ergo istae duae verae simul: ‘Homo est probus’ et ‘Homo est turpis’; sed ad hanc: ‘Homo est turpis’, sequitur ista: ‘Homo non est probus’; ergo istae sunt simul verae: ‘Homo est probus—Homo non est probus’. Et eadem ratione istae duae: ‘Homo est pulcher—Homo non est pulcher’.
It can be according to perfect contrariety, as shameful (that is, dishonorable) is opposed to worthy (that is, honorable) and ugly (that is, deformed in body) is opposed to beautiful. But the reasoning by which the affirmative enunciation “man is worthy” is true (namely, by some worthy man existing) is the same as the reasoning by which “man is shameful” is true (namely, by a shameful man existing). Therefore, these two enunciations are at once true, “man is worthy” and “man is shameful.” But the enunciation “man is not worthy” follows upon “man is shameful.” Therefore, the two enunciations, “man is worthy” and “man is not worthy” are at once true. By the same reasoning these two are true: “man is beautiful” and “man is not beautiful.”
Peri.L11
Alia autem oppositio attenditur secundum perfectum et imperfectum, sicut moveri opponitur ad motum esse et fieri ad factum esse, unde ad fieri sequitur non esse eius quod fit, in permanentibus, quorum esse est perfectum; secus autem est in successivis, quae habent esse imperfectum. Sic ergo haec est vera: ‘Homo est albus’, quodam homine existente albo, et, pari ratione, quia quidam homo fit albus, haec est vera, ‘Homo fit albus’, ad quam sequitur: ‘Homo non est albus’; ergo hae duae sunt simul verae: ‘Homo est albus—Homo non est albus’.
The other opposition is according to the complete and incomplete, as “to be in movement” is opposed to “to have been moved,” and “becoming” to “to have become.” Thus, the non-being of that which is coming to be in permanent things, whose being is complete, follows upon the becoming, but this is not so in successive things, whose being is incomplete. Thus, “man is white” is true because a white man exists; by the same reasoning, because a man is becoming white, the enunciation “man is becoming white” is true, upon which it follows that “man is not white.” Therefore, the two enunciations, “man is white” and “man is not white” are at once true.
Peri.L11
153. Deinde cum dicit: Videbitur autem et cetera, excludit id quod faceret dubitationem circa praedicta.
Then, when he says: at first sight this might seem paradoxical (17b34), he excludes what might present a difficulty in relation to what has been said.
Peri.L11
Et dicit quod subito, id est primo aspectu, videtur hoc esse inconveniens quod dictum est, quia hoc quod dico: ‘Homo non est albus’, videtur idem significare cum hoc quod dico: ‘Nullus homo est albus’; sed ipse hoc removet dicens quod neque idem significant neque ex necessitate sunt simul vera, sicut ex praedictis manifestum est.
At first sight, he says, what has been stated seems to be inconsistent; for “man is not white” seems to signify the same thing as “no man is white.” But he rejects this when he says that they neither signify the same thing, nor are they at once true necessarily, as is evident from what has been said.
Peri.L11
L. 12 (Α.7–8, 17b38–18a27)Only one negation opposed to one affirmation
Quod uni affirmationi una sola negatio opponitur
Only one negation opposed to one affirmation
Peri.L12
17b38. Manifestum est autem quoniam una negatio unius affirmationis est.
17b38. It is evident also that there is one negation of one affirmation.
Peri.L12
17b39. Hoc enim idem oportet negare negationem quod affirmatio affirmavit, et de eodem, vel de aliquo singularium vel de aliquo universalium, vel universaliter vel non universaliter.
17b39. For the negation must deny the same thing that the affirmation affirms, and of the same subject, either something singular, or something universal, and either universally or not universally.
Peri.L12
18a2. Dico autem ut: ‘Est Socrates albus—Socrates albus non est’. Si autem aliud aliquid vel de alio idem, non opposita, sed erit ab eo diversa. Huic vero quae est ‘Omnis homo albus est’, illa quae est ‘Non omnis homo albus est’. Illi vero quae est ‘Aliquis homo albus est’, illa quae est ‘Nullus homo albus est’. Illi autem quae est ‘Homo albus est’, illa quae est ‘Non est homo albus’.
18a2. For example, the negation of “Socrates is white” is “Socrates is not white.” (If something else is said of the same subject or the same thing of a different subject, it will not be opposed to it but different from it.) The negation opposed to “every man is white” is “not every man is white”; to “some man is white,” “no man is white”; to “man is white,” “man is not white.”
Peri.L12
18a8. Manifestum est ergo quoniam uni negationi una affirmatio opposita est, et quoniam aliae sunt contrariae, aliae contradictorie, et quae sunt hae, dictum est, et quoniam non omnis vera vel falsa contradictio, et quare, et quando vera vel falsa.
18a8. We have said that there is one negation opposed contradictorily to one affirmation, and what these are; and that the others are contraries, and what these are; and that in every contradiction one is not always true and the other false, and what the reason is for this, and when it is the case that one is true and the other false.
Peri.L12
18a13. Una autem est affirmatio et negatio quae unum de uno significat, vel cum sit universale universaliter vel non similiter. Ut ‘Omnis homo albus est—Non est omnis homo albus’; ‘Nullus homo albus est—Quidam homo albus est’, si ‘album’ unum significat.
18a13. Affirmation or negation is one when one thing is signified of one thing, whether the subject is universal and is taken universally, or not, as in “every man is white” and “not every man is white”; “man is white” and “man is not white”; “no man is white” and “some man is white” (provided that “white” signifies one thing).
Peri.L12
18a18. Sin vero duobus unum nomen est positum ex quibus non fit unum, non est una affirmatio.
18a18. But if one name is imposed for two things, from which there is not one thing, the affirmation is not one.
Peri.L12
18a19. Ut, si quis ponat hoc nomen ‘tunica’ homini et equo et dicat: ‘Tunica est alba’, haec non est una affirmatio nec negatio.
18a19. For example, if someone were to impose the name “cloak” on horse and man, the enunciation “cloak is white” would not be one affirmation, nor would “cloak is not white” be one negation.
Peri.L12
18a21. Nihil enim hoc differt dicere quam <...> ‘Est equus albus et est homo albus’. Si ergo haec multa significant et sunt plures, manifestum est quoniam et prima multa vel nihil significat. Neque enim est aliquid homo equus.
18a21. For this is no different from saying “horse and man is white,” and this no different from saying, “horse is white and man is white.” If, then, these signify many things and are many, it is evident that the first enunciation [“cloak is white”] signifies many things—or nothing, for there is not such a thing as a horse-man.
Peri.L12
18a26. Quare nec in his necesse est hanc quidem contradictionem veram esse, illam vero falsam.
18a26. Consequently, in such enunciations it is not necessary that one contradictory be true and the other false.
Peri.L12
154. Manifestum est autem quoniam una negatio et cetera. Postquam Philosophus distinxit diversos modos oppositionum in enuntiationibus, nunc intendit ostendere quod uni affirmationi una negatio opponitur.
It is evident also that there is one negation. Having distinguished the diverse modes of opposition in enunciations, the Philosopher now proposes to show that there is one negation opposed to one affirmation.
Peri.L12
Et circa hoc duo facit:
About this he does two things:
Peri.L12
primo ostendit quod uni affirmationi opponitur una negatio;
first, he shows that there is one negation opposed to one affirmation;
Peri.L12
secundo ostendit quae sit una affirmatio vel negatio, ibi: Una autem <est> affirmatio et cetera.
second, he manifests what one affirmation and negation are, at: affirmation or negation is one when one thing is signified of one thing (18a13; [160]).
Peri.L12
Circa primum tria facit:
About the first he does three things:
Peri.L12
primo proponit quod intendit;
first, he proposes the point;
Peri.L12
secundo manifestat, ibi: Hoc enim <idem> oportet et cetera;
second, he manifests it, at: for the negation must deny (17b39; [156]);
Peri.L12
tertio epilogat quae dicta sunt, ibi: Manifestum est ergo et cetera.
third, he gives a summary of what has been said, at: we have said that there is one negation (18a8; [159]).
Peri.L12
155. Dicit ergo primo manifestum esse quod unius affirmationis est una sola negatio.
He says, then, that it is evident that there is only one negation of one affirmation.
Peri.L12
Et hoc quidem fuit necessarium hic dici, quia, cum posuerit plura oppositionum genera, videbatur quod uni affirmationi duae negationes opponerentur, sicut huic affirmativae: ‘Omnis homo est albus’, videtur secundum praedicta opponi haec negativa: ‘Nullus homo est albus’, et haec: ‘Quidam homo non est albus’. Sed, si quis recte consideret, huius affirmativae: ‘Omnis homo est albus’, negatio est sola ista: ‘Quidam homo non est albus’, quae solummodo removet ipsam, ut patet ex sua aequipollenti, quae est: ‘Non omnis homo est albus’; universalis vero negativa includit quidem in suo intellectu negationem universalis affirmativae, in quantum includit particularem negativam, sed supra hoc aliquid addit, in quantum scilicet importat non solum remotionem universalitatis, sed removet quamlibet partem ipsius; et sic patet quod sola una est negatio universalis affirmationis. Et idem apparet in aliis.
It is necessary to make this point here because he has posited many kinds of opposition and it might appear that two negations are opposed to one affirmation. Thus it might seem that the negative enunciations, “no man is white” and “some man is not white” are both opposed to the affirmative enunciation “every man is white.” But if one carefully examines what has been said, it will be evident that the only negative opposed to “every man is white” is “some man is not white,” which merely removes it, as is clear from its equivalent, “not every man is white.” It is true that the negation of the universal affirmative is included in the understanding of the universal negative inasmuch as the universal negative includes the particular negative, but the universal negative adds something over and beyond this inasmuch as it not only brings about the removal of universality but removes every part of it. Thus it is evident that there is only one negation of a universal affirmation, and the same thing is evident in the others.
Peri.L12
156. Deinde cum dicit: Hoc enim idem et cetera, manifestat propositum.
When he says: for the negation must deny the same thing (17b39), he manifests what he has said.
Peri.L12
Et primo per rationem;
First, he does this from reason;
Peri.L12
secundo per exempla, ibi: Dico autem ut: ‘Est Socrates albus’ et cetera.
second, by example, at: for example, the negation of “Socrates is white” (18a2; [157]).
Peri.L12
Ratio autem sumitur ex hoc quod supra dictum est quod negatio opponitur affirmationi quae est eiusdem de eodem. Ex quo hic accipitur quod negationem oportet negare illud idem praedicatum quod affirmatio affirmavit, et de eodem subiecto, sive illud subiectum sit aliquid singulare sive aliquid universale, vel universaliter vel non universaliter sumptum. Sed hoc non contingit nisi uno modo, ita scilicet ut negatio neget id quod affirmatio posuit et nihil aliud; ergo uni affirmationi opponitur una sola negatio.
The reasoning is taken from what has already been said, namely, that negation is opposed to affirmation when the enunciations are of the same thing of the same subject. Here he says that the negation must deny the same predicate the affirmation affirms, and of the same subject, whether that subject he something singular or something universal, either taken universally or not taken universally. But this can only be done in one way, that is, when the negation denies what the affirmation posits, and nothing else. Therefore, there is only one negation opposed to one affirmation.
Peri.L12
157. Deinde cum dicit: Dico autem et cetera, manifestat propositum per exempla.
In manifesting this by example, he says: for example, the negation of “Socrates is white” (18a2).
Peri.L12
Et primo in singularibus: huic enim affirmationi: ‘Socrates est albus’, haec sola opponitur: ‘Socrates non est albus’, tanquam eius propria negatio. Si vero esset aliud praedicatum vel aliud subiectum, non esset negatio opposita, sed omnino diversa, sicut ista: ‘Socrates non est musicus’, non opponitur ei quae est: ‘Socrates est albus’, neque etiam illa: ‘Plato est albus’.
First, he takes examples of singulars. Thus, “Socrates is not white” is the proper negation opposed to “Socrates is white.” If there were another predicate or another subject, it would not be the opposed negation, but wholly different. For example, “Socrates is not musical” is not opposed to “Socrates is white,” nor is “Plato is white” opposed to “Socrates is not white.”
Peri.L12
Secundo manifestat idem quando subiectum affirmationis est universale universaliter sumptum, sicut huic affirmationi: ‘Omnis homo est albus’, opponitur sicut propria eius negatio: ‘Non omnis homo est albus’, quae aequipollet particulari negativae.
Second, he manifests the same thing in an affirmation with a universal universally taken as the subject. Thus, “not every man is white,” which is equivalent to the particular negative, is the proper negation opposed to the affirmation “every man is white.”
Peri.L12
Tertio ponit <exemplum> quando affirmationis subiectum est universale particulariter sumptum, et dicit quod huic affirmationi: ‘Aliquis homo est albus’, opponitur tanquam propria eius negatio: ‘Nullus homo est albus’; nam nullus dicitur quasi ‘non ullus’, id est, ‘non aliquis’.
Third, he gives an example in which the subject of the affirmation is a universal taken particularly. The proper negation opposed to the affirmation “some man is white” is “no man is white,” for to say “no” is to say “not any,” that is, “not some.”
Peri.L12
Quarto ponit exemplum quando affirmationis subiectum est universale indefinite sumptum, et dicit quod isti affirmationi: ‘Homo est albus’, opponitur sicut propria negatio illa quae est: ‘Non est homo albus’.
Fourth, he gives as an example enunciations in which the subject of the affirmation is the universal taken indefinitely. “Man is not white” is the proper negation opposed to the affirmation “man is white.”
Peri.L12
158. Sed videtur hoc esse contra id quod supra dictum est, quod negativa indefinita verificatur simul cum indefinita affirmativa: negatio non simul potest verificari cum opposita affirmatione, quia non contingit de eodem affirmare et negare.
The last example used to manifest his point seems to be contrary to what he has already said, namely, that the indefinite negative and the indefinite affirmative can be simultaneously verified. A negation and its opposite affirmation cannot be simultaneously verified, since it is not possible to affirm and deny of the same subject.
Peri.L12
Sed ad hoc dicendum est quod oportet quod hic dicitur intelligi quando negatio ad idem refertur quod affirmatio continebat; et hoc potest esse dupliciter:
But what Aristotle is saying here must be understood of the negation when it is referred to the same thing the affirmation contained, and this is possible in two ways:
Peri.L12
uno modo quando affirmatur aliquid inesse universali ratione sui ipsius, quod est per se de eo praedicari, et hoc ipsum negatio negat;
in one way, when something is affirmed to belong to man by reason of what he is (which is to be predicated of the same thing per se), and the negation denies this very thing;
Peri.L12
alio modo quando aliquid affirmatur de universali ratione sui singularis, et pro eodem de eo negatur.
second, when something is affirmed of the universal by reason of its singular, and the same thing is denied of it.
Peri.L12
159. Deinde cum dicit: Manifestum est ergo et cetera, epilogat quae dicta sunt.
He concludes by summarizing what has been said: we have said that there is one negation (18a8).
Peri.L12
Et concludit manifestum esse ex praedictis quod uni affirmationi opponitur una negatio et quod oppositarum affirmationum et negationum aliae sunt contrariae, aliae contradictoriae, et dictum est quae sunt utraeque (tacet autem de subcontrariis, quia non sunt recte oppositae, ut supra dictum est); <dictum est> etiam quod non omnis contradictio est vera vel falsa (et sumitur hic large ‘contradictio’ pro qualicumque oppositione affirmationis et negationis: nam in his quae sunt vere contradictoriae, semper una est vera et altera falsa); quare autem in quibusdam oppositis hoc non verificetur, dictum est supra (quia scilicet quaedam non sunt contradictoriae, sed contrariae, quae possunt simul esse falsae; contingit etiam affirmationem et negationem non proprie opponi, et ideo contingit eas esse veras); dictum est autem quando altera semper est vera, altera falsa (quia scilicet in his quae sunt vere contradictoriae).
He considers it evident from what has been said that one negation is opposed to one affirmation, and that of opposite affirmations and negations, one kind are contraries, the other contradictories, and that what each kind is has been stated. He does not speak of subcontraries because it is not accurate to say that they are opposites, as was said above. He also says here that it has been shown that not every contradiction is true or false, “contradiction” being taken here broadly for any kind of opposition of affirmation and negation, for in enunciations that are truly contradictory, one is always true and the other false. The reason why this may not be verified in some kinds of opposites has already been stated, namely, because some are not contradictories but contraries, and these can be false at the same time. It is also possible for affirmation and negation not to be properly opposed, and consequently to be true at the same time. It has been stated, however, when one is always true and the other false, namely, in those that are truly contradictories.
Peri.L12
160. Deinde cum dicit: Una autem est affirmatio et cetera, ostendit quae sit affirmatio vel negatio una.
Then he explains what one affirmation or negation is where he says: affirmation or negation is one when one thing is signified of one thing (18a13).
Peri.L12
Quod quidem iam supra dixerat, ubi habitum est quod una est enuntiatio quae unum significat; sed, quia enuntiatio in qua aliquid praedicatur de aliquo universali universaliter multa sub se continet, intendit ostendere quod hoc non impedit unitatem enuntiationis.
He did in fact state this earlier when he said that an enunciation is one when it signifies one thing, but because the enunciation in which something is predicated of a universal (either universally or not universally) contains under it many things, he is going to show here that unity of enunciation is not impeded by this.
Peri.L12
Et circa hoc duo facit:
About this he does two things:
Peri.L12
primo ostendit quod unitas enuntiationis non impeditur per multitudinem quae continetur sub uno universali cuius ratio una est;
first, he shows that unity of enunciation is not impeded by the multitude contained under the universal, whose notion is one;
Peri.L12
secundo ostendit quod impeditur unitas enuntiationis per multitudinem quae continetur sub sola nominis unitate, ibi: Si vero duobus et cetera.
second, he shows that unity of enunciation is impeded by the multitude contained under the unity of a name only, at: but if one name is imposed for two things (18a18; [161]).
Peri.L12
Dicit ergo primo quod una est affirmatio et negatio cum unum significatur de uno, sive illud unum quod subiicitur sit universale universaliter sumptum, vel non sit aliquid tale, sed sit universale particulariter sumptum aut etiam indefinite, aut etiam si subiectum sit singulare.
He says, then, that an affirmation or negation is one when one thing is signified of one thing, whether the one thing that is subjected be a universal taken universally, or not—that is, it may be a universal taken particularly or indefinitely, or even a singular.
Peri.L12
Et exemplificat de diversis, sicut ista universalis affirmatio est una: ‘Omnis homo est albus’, et similiter particularis negativa quae est eius negatio, scilicet: ‘Non est <omnis> homo albus’; et subdit alia exempla quae sunt manifesta.
He gives examples of the different kinds, such as the universal affirmative “every man is white” and the particular negative, which is its negation, “not every man is white,” each of which is one. There are other examples which are evident.
Peri.L12
In fine autem apponit quamdam conditionem quae requiritur ad hoc quod quaelibet harum sit una, si scilicet ‘album’, quod est praedicatum, unum significat. Nam sola multitudo praedicati impediret unitatem enuntiationis, ideo autem universalis propositio una est, quamvis sub se multitudinem singularium comprehendat, quia praedicatum non attribuitur multis singularibus secundum quod sunt in se divisa, sed secundum quod uniuntur in uno communi.
At the end he states a condition that is required for any of them to be one, namely, provided the “white,” which is the predicate, signifies one thing; for a multiple predicate with a subject signifying one thing would also impede the unity of an enunciation. The universal proposition is therefore one, even though it comprehends a multitude of singulars under it, for the predicate is not attributed to many singulars according as each is divided from the other, but according as they are united in one common thing.
Peri.L12
161. Deinde cum dicit: Si vero duobus et cetera, ostendit quod sola unitas nominis non sufficit ad unitatem enuntiationis.
When he says: but if one name is imposed for two things (18a18), he shows that unity of name alone does not suffice for unity of an enunciation.
Peri.L12
Et circa hoc quatuor facit:
About this, he does four things:
Peri.L12
primo proponit quod intendit;
first, he makes the point;
Peri.L12
secundo exemplificat, ibi: Ut, si quis ponat et cetera;
second, he gives an example, at: for example, if someone were to impose (18a19; [162]);
Peri.L12
tertio probat, ibi: Nihil enim hoc differt et cetera;
third, he proves it, at: for this is no different from saying (18a21; [162]);
Peri.L12
quarto infert corollarium ex dictis, ibi: Quare nec in his et cetera.
fourth, he infers a corollary from what has been said, at: consequently, in such enunciations (18a26; [163]).
Peri.L12
Dicit ergo primo quod, si unum nomen imponatur duabus rebus ex quibus non fit unum, non est affirmatio una.
Therefore, he first says that if one name is imposed for two things, that from which one thing is not formed, there is not one affirmation (18a18).
Peri.L12
Quod autem dicit: ex quibus non fit unum, potest intelligi dupliciter. Uno modo, ad excludendum hoc quod multa continentur sub uno universali, sicut homo, equus sub animali et hoc nomen ‘animal’ significat utrumque, non secundum quod sunt multa et differentia ab invicem, sed secundum quod uniuntur in natura generis.
The from which one thing is not formed can be understood in two ways. It can be understood as excluding the many that are contained under one universal, as man and horse under animal, for the name “animal” signifies both not as they are many and different from each other, but as they are united in the nature of the genus.
Peri.L12
Alio modo, et melius, ad excludendum hoc quod ex multis partibus fit unum, sive sint partes rationis, sicut genus et differentia sunt partes definitionis, sive sint partes integrales alicuius compositi, sicut ex lapidibus et lignis fit domus.
It can also be understood, and this would be more accurate, as excluding the many parts from which something one is formed, whether these are the parts of its idea, the genus and the difference (which are parts of the definition), or the integral parts of some composite (like the stones and wood from which a house is made).
Peri.L12
Si ergo sit tale praedicatum quod attribuatur rei, requiritur ad unitatem enuntiationis quod multa quae significantur concurrant in unum secundum aliquem dictorum modorum; unde non sufficiet sola unitas vocis. Si vero sit tale praedicatum quod referatur ad vocem, sufficiet unitas vocis, ut si dicam: ‘Canis est nomen’.
If, then, there is such a predicate which is attributed to a thing, the many that are signified must concur in one thing according to some of the modes mentioned in order that there be one enunciation. Unity of vocal sound alone would not suffice. However, if there is such a predicate which is referred to vocal sound, unity of vocal sound would suffice, as in “‘dog’ is a name.”
Peri.L12
162. Deinde cum dicit: Ut, si quis ponat et cetera, exemplificat quod dictum est.
He gives an example of what he means, at: for example, if someone were to impose the name (18a19).
Peri.L12
Ut, si aliquis hoc nomen ‘tunica’ imponat ad significandum hominem et equum, et sic, si dicatur: Tunica est alba, vel: ‘Tunica non est alba’, non erit affirmatio una neque negatio.
That is, if someone were to impose the name “cloak” to signify man and horse, and then said, “cloak is white,“ or “cloak is not white,” there would not be one affirmation, nor would there be one negation.
Peri.L12
Deinde cum dicit: Nihil enim hoc differt et cetera, probat quod dixerat, tali ratione:
He proves this where he says: for this is no different from saying (18a21). His argument is as follows.
Peri.L12
Si ‘tunica’ significat hominem et equum, nihil differt si dicatur: ‘Tunica est alba’, aut si dicatur: ‘Homo est albus et equus est albus’; sed istae duae: ‘Homo est albus’ et ‘Equus est albus’, significant multa et sunt plures enuntiationes; ergo etiam ista: ‘Tunica est alba’, significat multa, et hoc si significet hominem et equum ut res diversas; si vero significet hominem et equum ut componentia unam rem, nihil significat, quia non est aliqua res quae componatur ex homine et equo.
If “cloak” signifies man and horse, there is no difference between saying, “cloak is white” and saying, “man is white and horse is white.” But “man is white and horse is white” signify many, and are many enunciations. Therefore, the enunciation “cloak is white” signifies many things. This is the case if “cloak” signifies man and horse as diverse things, but if it signifies man and horse as one thing, it signifies nothing, for there is not any thing composed of man and horse.
Peri.L12
Quod autem dicit quod non differt dicere: ‘Tunica est alba’ et: ‘Homo est albus et equus est albus’, non est intelligendum quantum ad veritatem et falsitatem; nam haec copulativa: ‘Homo est albus et equus est albus’, non potest esse vera nisi utraque pars sit vera, sed haec: ‘Tunica est alba’, praedicta positione facta, potest esse vera etiam altera existente falsa, alioquin non oporteret distinguere multiplices propositiones ad solvendum rationes sophisticas. Sed hoc est intelligendum quantum ad unitatem et multiplicitatem: nam, sicut cum dicitur: ‘Homo est albus et equus est albus’, non invenitur aliqua una res cui attribuatur praedicatum, ita etiam nec cum dicitur: ‘Tunica est alba’.
When Aristotle says that there is no difference between saying “cloak is white” and “man is white and horse is white,” it is not to be understood with respect to truth and falsity. For the copulative enunciation “man is white and horse is white” cannot be true unless each part is true; but the enunciation “cloak is white,” under the condition given, can be true even when one is false; otherwise, it would not be necessary to distinguish multiple propositions to solve sophistic arguments. Rather, it is to be understood with respect to unity and multiplicity, for just as in “man is white and horse is white,” there is not some one thing to which the predicate is attributed, so also in “cloak is white.”
Peri.L12
163. Deinde cum dicit: Quare nec in his et cetera, concludit ex praemissis quod nec in his affirmationibus et negationibus, quae utuntur subiecto aequivoco, semper oportet unam esse veram et aliam falsam, quia scilicet negatio potest aliud negare quam affirmatio affirmet.
When he says: consequently, it is not necessary in such enunciations (18a26), he concludes from what has been said that in affirmations and negations that use an equivocal subject, one need not always be true and the other false, since the negation may deny something other than the affirmation affirms.

18a28. In his ergo quae sunt et quae facta sunt, necesse est affirmationem vel negationem veram vel falsam esse. In universalibus quidem universaliter semper hanc quidem veram, illam vero falsam. Et in his quae sunt singularia, quemadmodum dictum est. In his vero quae in universalibus non universaliter dicuntur, non est necesse: dictum est autem et de his. In singularibus vero et futuris non similiter.
18a28. In enunciations about that which is or has taken place, the affirmation or the negation must be true or false. And in enunciations of universals as universal, one is always true and the other false, and also in enunciations of singulars, as has been said; but in enunciations of universals not taken universally, it is not necessary that one be true and the other false. We have already spoken of these. However, in enunciations about future singular things, the case is not the same.
Peri.L13
18a34. Nam si omnis affirmatio vel negatio vera vel falsa est, et omne necesse est vel esse vel non esse.
18a34. For if every affirmation or negation is true or false, then everything belongs or does not belong to a thing necessarily.
Peri.L13
18a35. Si hic quidem dicat futurum aliquid, ille vero non dicat hoc idem ipsum, manifestum est quoniam necesse est verum dicere alterum ipsorum, si omnis affirmatio vera vel falsa est: utraque enim non erunt simul in talibus.
18a35. For if one person says a thing will be such, and another says it will not be this very thing, clearly one of them must be speaking the truth if every affirmation is true or false. For it will not both belong and not belong to the thing simultaneously in such cases.
Peri.L13
Nam si verum est dicere quoniam album vel non album est, necesse est esse album vel non album, et, si est album vel non album, verum est vel affirmare vel negare. Et, si non est, mentitur, et, si mentitur, non est; quare necesse est aut affirmationem aut negationem veram esse.
—For if it is true to say that a thing is white or is not white, it must necessarily be white or not white. And if it is white or not white, it was true to affirm or deny it. And if it does not belong to it, it is false to say that it does, and if it is false to say that it does, then it does not belong to it. Consequently, it is necessary that either the affirmation or negation be true.
Peri.L13
Nihil igitur neque est neque fit nec casu nec utrumlibet, nec erit nec non erit, sed ex necessitate omnia.
—If this is so, then nothing either is, or takes place fortuitously or indeterminately in relation to two alternatives, or will be or will not be; but everything takes place of necessity.
Peri.L13
Et non utrumlibet: aut enim qui dicit verus est aut qui negat; similiter enim vel fieret vel non fieret: utrumlibet enim nihil magis sic vel non sic se habet aut habebit.
—And is not indeterminate to either of two alternatives (for the supposition is that either the one who affirms it or the one who denies it is speaking the truth). But if everything does not take place of necessity, it could take place or not take place as well, for what is indeterminate to either of two alternatives happens or will happen no more in this way than not.
Peri.L13
18b9. Amplius, si est album nunc, verum erat dicere primo quoniam erit album. Quare semper verum fuit dicere quodlibet eorum quae facta sunt, quoniam erit; quod si semper verum est dicere quoniam est vel erit, non potest hoc non esse vel non futurum esse.
18b9. Furthermore, on such a supposition, if something is now white, it was true to say formerly that it will be white; therefore, it was always true to say of anything that has taken place that it will be. But if it was always true to say that it is or will be, it is not possible for this not to be, nor that it will not be.
Peri.L13
Quod autem non potest non fieri, impossibile est non fieri; et quod impossibile est non fieri, necesse est fieri; omnia ergo quae futura sunt, necesse est fieri. Nihil igitur utrumlibet neque casu erit: nam si casu, non ex necessitate.
And when a thing cannot not take place, it is impossible that it not take place, and when it is impossible that it not take place, it is necessary that it take place; all things that will be, then, must necessarily take place. Therefore, nothing will be indeterminate to either of two alternatives, nor fortuitous; for if it were fortuitous, it would not take place of necessity.
Peri.L13
18b17. At vero nec quoniam neutrum verum est contingit dicere, ut quoniam neque erit neque non erit.
18b17. But still it is not possible to say that neither is true—that is, to say that a thing neither will take place nor will not take place.
Peri.L13
18b18. Primum enim, cum sit affirmatio falsa, erit negatio non vera, et, cum haec sit falsa, contingit affirmationem esse non veram.
18b18. In the first place, though the affirmation be false, the negation will not be true, and though the negation be false, the affirmation will not be true.
Peri.L13
18b20. Adhuc, si verum est dicere quoniam album est et magnum, oportet utraque esse, si vero erit cras, oportet esse cras. Si autem neque erit neque non erit cras, non erit utrumlibet, ut navale bellum: oportebit enim neque fieri navale bellum neque non fieri navale bellum.
18b20. Second, if it is true to say that a thing is white and large, both necessarily belong to it; and if they will belong to it the next day, they will necessarily belong to it the next day. But if a thing neither will be nor will not be tomorrow, it would not be indeterminate to either of two alternatives. For example, in the case of a naval battle, it would be necessary that the naval battle neither take place nor not take place tomorrow.
Peri.L13
164. In his ergo quae sunt et quae facta sunt et cetera. Postquam Philosophus determinavit de oppositione enuntiationum et <ostendit> quomodo dividunt verum et falsum oppositae enuntiationes, hic inquirit de quodam quod poterat esse dubium, utrum scilicet id quod dictum est similiter inveniatur in omnibus enuntiationibus vel non.
In enunciations about that which is or has taken place. Now, that he has treated opposition of enunciations and has shown the way in which opposed enunciations divide truth and falsity, the Philosopher inquires about a question that might arise, namely, whether what has been said is found to be so in all enunciations or not.
Peri.L13
Et circa hoc duo facit:
About this he does two things:
Peri.L13
primo proponit dissimilitudinem;
first, he proposes a dissimilarity;
Peri.L13
secundo probat eam, ibi: Nam si omnis affirmatio et cetera.
second, he proves it, at: for if every affirmation or negation is true or false (18a34; [170]).
Peri.L13
165. Circa primum considerandum est quod Philosophus in praemissis triplicem differentiam enuntiationum assignavit,
In relation to the dissimilarity which he intends to prove, we should recall that the Philosopher has given three divisions of the enunciation.
Peri.L13
quarum prima fuit secundum unitatem enuntiationis, prout scilicet enuntiatio est una simpliciter vel coniunctione una;
The first was in relation to the unity of enunciation, and according to this it is divided into one simply and one by conjunction.
Peri.L13
secunda fuit secundum qualitatem, prout scilicet enunciatio est affirmativa vel negativa;
The second was in relation to quality, and according to this it is divided into affirmative and negative.
Peri.L13
tertia autem fuit secundum quantitatem, utpote quod enuntiatio quaedam est universalis, quaedam particularis, quaedam indefinita et quaedam singularis.
The third was in relation to quantity, and according to this it is either universal, particular, indefinite, or singular.
Peri.L13
166. Tangitur autem hic quarta differentia enuntiationum, secundum tempus: nam quaedam est de praesenti, quaedam de praeterito, quaedam de futuro; et haec etiam differentia potest accipi ex his quae supra dicta sunt: dictum est enim supra quod necesse est omnem enuntiationem esse ex verbo vel ex casu verbi, verbum autem est quod consignificat praesens tempus, sed casus verbi sunt qui significant tempus praeteritum vel futurum.
Here he treats of a fourth division of enunciation, according to time. Some enunciations are about the present, some about the past, some about the future. This division could be seen in what Aristotle has already said, namely, that every enunciation must have a verb or a mode of a verb, the verb being that which signifies the present time, the modes with past or future time.
Peri.L13
Potest autem accipi quinta differentia enuntiationum, secundum materiam, quae quidem differentia attenditur secundum habitudinem praedicati ad subiectum: nam, si praedicatum per se insit subiecto, dicetur esse enuntiatio in materia necessaria vel naturali, ut cum dicitur: ‘Homo est animal’, vel: ‘Homo est risibile’; si vero praedicatum per se repugnet subiecto quasi excludens rationem ipsius, dicetur enuntiatio esse in materia impossibili sive remota, ut cum dicitur: ‘Homo est asinus’; si vero medio modo se habeat praedicatum ad subiectum, ut scilicet <nec> per se insit nec per se repugnet, dicetur enuntiatio esse in materia possibili sive contingenti.
In addition, a fifth division of the enunciation can be made in regard to matter, which is taken from the relationship of the predicate to the subject. If the predicate is in itself in the subject, it will be said to be an enunciation in necessary or natural matter. Examples of this are “man is an animal” and “man is risible.” If the predicate is repugnant to the subject in itself, as excluding the notion of it, it is said to be an enunciation in impossible or remote matter, such as the enunciation, “man is an ass.” If the predicate is related to the subject in a way midway between these two, being neither in itself repugnant to the subject nor in itself in it, the enunciation is said to be in possible or contingent matter.
Peri.L13
167. His igitur differentiis enuntiationum consideratis, non similiter se habet iudicium de veritate et falsitate in omnibus. Unde Philosophus dicit, ex praemissis concludens, quod in his quae sunt, id est in propositionibus de praesenti, et in his quae facta sunt, id est in enuntiationibus de praeterito, necesse est quod affirmatio vel negatio determinate sit vera vel falsa. Diversificatur tamen hoc secundum diversam quantitatem enuntiationis: nam in enuntiationibus in quibus de universalibus subiectis aliquid universaliter praedicatur, necesse est quod semper una sit vera, scilicet affirmativa vel negativa, et altera falsa, quae scilicet ei opponitur: dictum est enim supra quod negatio enuntiationis universalis in qua aliquid universaliter praedicatur est negativa non universalis, sed particularis, et e converso universalis negativa non est directe negatio affirmativae universalis, sed particularis; et sic oportet, secundum praedicta, quod semper una earum sit vera et altera falsa, in quacumque materia. Et eadem ratio est in singularibus enuntiationibus, quae etiam contradictorie opponuntur, ut supra habitum est. Sed in enuntiationibus in quibus aliquid praedicatur de universali non universaliter, non necesse est quod semper una sit vera et altera sit falsa, quia possunt esse ambae simul verae, ut supra ostensum est.
Given these differences of enunciations, the judgment of truth and falsity is not alike in all. Accordingly, the Philosopher says (18a28), as a conclusion from what has been established: in enunciations about that which is, that is, in propositions about the present, or has taken place, that is, in enunciations about the past, the affirmation or the negation must be determinately true or false. However, this differs according to the different quantity of the enunciations. In enunciations in which something is universally predicated of universal subjects, one must always be true, either the affirmative or negative, and the other false, namely, the one opposed to it. For as was said above, the negation of a universal enunciation in which something is predicated universally is not the universal negative, but the particular negative, and conversely, the universal negative is not directly the negation of the universal affirmative, but the particular negative. According to the foregoing, then, one of these must always be true and the other false in any matter whatever. And the same is the case in singular enunciations, which are also opposed contradictorily. However, in enunciations in which something is predicated of a universal but not universally, it is not necessary that one always be true and the other false, for both could be at once true.
Peri.L13
168. Et hoc quidem ita se habet quantum ad propositiones quae sunt de praeterito vel de praesenti. Sed, si accipiamus enuntiationes quae sunt de futuro, etiam similiter se habent, quantum ad oppositiones, quae sunt de universalibus, universaliter vel non universaliter sumptis: nam in materia necessaria omnes affirmativae determinate sunt verae, ita in futuris sicut in praeteritis vel praesentibus, negativae vero falsae; in materia autem impossibili, e contrario; in contingenti vero universales sunt falsae et particulares sunt verae, ita in futuris sicut in praesentibus vel praeteritis; in indefinitis autem utraque simul est vera, <ita> in futuris sicut in praesentibus vel praeteritis.
The case as it was just stated has to do with propositions about the past or the present. Enunciations about the future that are of universals taken either universally or not universally are also related in the same way in regard to oppositions. In necessary matter, all affirmative enunciations are determinately true and negative enunciations are determinately false (this holds for enunciations in future time as well as in past and present time). In impossible matter, the contrary is the case. In contingent matter, however, universal enunciations are false and particular enunciations true. This is the case in enunciations about the future as well as those of the past and present. In indefinite enunciations, both are at once true in future enunciations as well as in those of the present or the past.
Peri.L13
169. Sed in singularibus et futuris est quaedam dissimilitudo. Nam in praeteritis et praesentibus necesse est quod altera oppositarum determinate sit vera et altera falsa, in quacumque materia; sed in singularibus quae sunt de futuro, hoc non est necesse quod una determinate sit vera et altera falsa. Et hoc quidem quantum ad materiam contingentem: nam quantum ad materiam necessariam et impossibilem, similis ratio est in futuris singularibus sicut in praesentibus et praeteritis. Nec tamen Aristoteles mentionem fecit de materia contingenti, quia illa proprie ad singularia pertinent quae contingenter eveniunt, quae autem per se insunt vel repugnant attribuuntur singularibus secundum universalium rationes.
In singular and future enunciations (18a28), however, there is a difference. In past and present singular enunciations, one of the opposites must be determinately true and the other false in any matter whatsoever, but in singulars that are about the future, it is not necessary that one be determinately true and the other false. This holds with respect to contingent matter; with respect to necessary and impossible matter, the rule is the same as in enunciations about the present and the past. Aristotle has not mentioned contingent matter until now because those things that take place contingently pertain exclusively to singulars, whereas those that in itself belong or are repugnant are attributed to singulars according to the notions of their universals.
Peri.L13
Circa hoc igitur versatur tota praesens intentio: utrum in enuntiationibus singularibus de futuro in materia contingenti necesse sit quod determinate una oppositarum sit vera et altera sit falsa.
Aristotle is therefore wholly concerned here with this question: whether, in singular enunciations about the future in contingent matter, it is necessary that one of the opposites be determinately true and the other determinately false?
Peri.L13
170. Deinde cum dicit: Nam si omnis affirmatio et cetera, probat praemissam differentiam.
He proves that there is a difference between these opposites and the others where he says: for if every affirmation or negation is true or false (18a34).
Peri.L13
Et circa hoc duo facit:
And here he does two things:
Peri.L13
primo probat propositum ducendo ad inconveniens;
first, he proves it by showing that the opposite position leads to what is unlikely;
Peri.L13
secundo ostendit esse impossibilia illa quae sequuntur, ibi: Quae ergo contingunt inconvenientia et cetera.
second, he shows that what follows from this position is impossible, at: these absurd consequences and others like them (18b26; [176]).
Peri.L13
Circa primum duo facit:
About the first he does two things:
Peri.L13
primo ostendit quod in singularibus et futuris non semper potest determinate attribui <veritas> alteri oppositorum;
first, he shows that in enunciations about future singulars, truth cannot always be determinately attributed to one of the opposites;
Peri.L13
secundo ostendit quod non potest esse quod utraque veritate careat, ibi: At vero neque quoniam, et cetera.
second, he shows that both cannot lack truth, where he says: but still it is not possible to say that neither is true (18b17; [175]).
Peri.L13
Circa primum ponit duas rationes.
He gives two arguments with respect to the first point.
Peri.L13
In quarum prima ponit quamdam consequentiam, scilicet quod, si omnis affirmatio vel negatio determinate est vera vel falsa, ita in singularibus et futuris sicut in aliis, consequens est quod omnia necesse sit vel determinate esse vel non esse.
In the first of these, he states a certain consequence, namely, that if every affirmation or negation is determinately true or false, in future singulars as in the others, it follows that all things must determinately be or not be.
Peri.L13
Deinde cum dicit: Si hic quidem et cetera. (vel: Si itaque hic quidem, ut habetur in Graeco), probat consequentiam praedictam.
He proves this consequence where he says: therefore, if one person says (18a35), or as it is in the Greek, for if one person says something will be.
Peri.L13
Ponamus enim quod sint duo homines quorum unus dicat aliquid esse futurum, puta quod Socrates currat, alius vero dicat hoc idem ipsum non esse futurum; supposita praemissa positione, scilicet quod in singularibus et futuris contingit alteram esse veram, scilicet vel affirmativam vel negativam, sequetur de necessitate quod alter eorum verum dicat, non autem uterque, quia non potest esse quod in singularibus propositionibus utraque sit simul vera, scilicet affirmativa et negativa, sed hoc habet locum solum in indefinitis. Ex hoc autem quod necesse est alterum eorum verum dicere, sequitur quod necesse sit determinate vel esse vel non esse.
Let us suppose, he argues, that there are two men, one of whom says something will take place in the future—for instance, that Socrates will run—and the other says this same thing will not take place. If the foregoing position is supposed (namely, that in singular future enunciations one of them will be true, either the affirmative or the negative), it would follow that only one of them is saying what is true, because in singular future propositions both cannot be at once true, that is, both the affirmative and the negative. This occurs only in indefinite propositions. Moreover, from the fact that one of them must be speaking the truth, it follows that it must determinately be or not be.
Peri.L13
Et hoc probat consequenter, quod ista duo se convertibiliter consequuntur, scilicet quod verum sit id quod dicitur et quod ita sit in re [Et hoc est quod manifestat consequenter], dicens quod, si verum est dicere quod album sit, ex necessitate sequitur quod ita sit in re; et si verum est negare, ex necessitate sequitur quod ita non sit; et e converso, quia, si ita est in re vel non est, ex necessitate sequitur quod sit verum affirmare vel negare. Et eadem etiam convertibilitas apparet in falso, quia, si aliquis mentitur, falsum dicens, ex necessitate sequitur quod non sit ita in re sicut ipse affirmat vel negat, et e converso, si non <est> ita in re sicut ipse affirmat vel negat, sequitur quod affirmans vel negans mentiatur.
Then he proves this from the fact that these two follow upon each other convertibly, namely, truth is that which is said and which is so in reality. And this is what he manifests when he says that if it is true to say that a thing is white, it necessarily follows that it is so in reality; and if it is true to deny it, it necessarily follows that it is not so. And conversely, if it is so in reality, or is not, it necessarily follows that it is true to affirm or deny it. The same convertibility is also evident in what is false, for if someone lies, saying what is false, it necessarily follows that in reality it is not as he affirms or denies it to be; conversely, if it is not in reality as he affirms or denies it to be, it follows that in affirming or denying it he lies.
Peri.L13
171. Est ergo processus huius rationis talis: Si necesse est quod omnis affirmatio vel negatio in singularibus et futuris sit vera vel falsa, necesse est quod omnis affirmans vel negans determinate dicat verum vel falsum; ex hoc autem sequitur quod omne necesse sit esse vel non esse; ergo, si omnis affirmatio vel negatio determinate sit vera, necesse est omnia determinate esse vel non esse.
The process of Aristotle’s reasoning is as follows. If every affirmation or negation about future singulars must be is true or false, it is necessary that everyone who affirms or denies determinately says what is true or false. From this, it follows that everything must be or not be. Therefore, if every affirmation or negation is determinately true, everything must determinately be or not be.
Peri.L13
Ex hoc ergo concludit ulterius quod omnia sint ex necessitate. Per quod triplex genus contingentium excluditur:
From this, he further concludes that all things are of necessity. This would exclude the three kinds of contingent things, which are these:
Peri.L13
172. quaedam enim contingunt in paucioribus, quae accidunt a casu vel fortuna;
some, which happen by chance or fortune, happen infrequently;
Peri.L13
quaedam vero se habent ad utrumlibet, quia scilicet non magis se habent ad unam partem quam ad aliam (ista procedunt ex electione);
others are indeterminate to either of two alternatives because they are not inclined more to one part than to another, and these proceed from choice;
Peri.L13
quaedam vero eveniunt ut in pluribus, sicut hominem in senectute canescere, quae causantur ex natura;
still others occur for the most part, such as men becoming gray in old age, which is caused by nature.
Peri.L13
si autem omnia ex necessitate evenirent, nihil horum contingentium esset.
If, however, everything took place of necessity, there would be none of these kinds of contingent things.
Peri.L13
Et ideo dicit: Nihil est, quantum ad ipsam permanentiam eorum quae permanent contingenter, neque fit, quantum ad productionem eorum quae contingenter causantur, nec casu, quantum ad ea quae sunt in minori parte sive in paucioribus, nec utrumlibet, quantum ad ea quae se habent aequaliter ad utrumque, scilicet esse vel non esse, et ad neutrum horum sunt determinata; quod significat cum subdit: nec erit nec non erit.
Therefore, Aristotle says, nothing is with respect to the very permanence of those things that are contingently permanent; or takes place with respect to those that are caused contingently; by chance with respect to those that take place for the least part, or infrequently; or is indeterminate to either of two alternatives with respect to those that are related equally to either of two (that is, to being or to non-being), and are determined to neither of these, which he signifies when he adds, or will be, or will not be.
Peri.L13
De eo enim quod est magis determinatum ad unam partem possumus determinate verum dicere quod hoc erit vel hoc non erit, sicut medicus de convalescente vere dicit: ‘Iste sanabitur’, licet forte ex aliquo accidente eius sanitas impediatur. Unde et Philosophus dicit in II De generatione quod futurus quis incedere, non incedet: de eo enim qui habet propositum determinatum ad incedendum, vere potest dici quod ipse incedet, licet per aliquod accidens impediatur eius incessus. Sed eius quod est ad utrumlibet proprium est quod, quia non determinatur magis ad unum quam ad alterum, non possit de eo determinate dici neque quod erit neque quod non erit.
For of that which is more determined to one part we can truly and determinately say that it will be or will not be, as (for example) the physician truly says of the convalescent, “He will be restored to health,” although by some accident his cure may be impeded. The Philosopher makes this same point when he says1 that a man about to walk might not walk. For it can be truly said of someone who has the determined intention to walk that he will walk, although by some accident his walking might be impeded. But in the case of that which is indeterminate to either of two, it cannot determinately be said of it either that it will be or that it will not be, for it is proper to it not to be determined more to one than to another.
Peri.L13
Quomodo autem sequatur quod nihil sit ad utrumlibet ex praemissa hypothesi, manifestat subdens quod, <si> omnis affirmatio vel negatio determinate sit vera, oportet quod vel ille qui affirmat vel ille qui negat dicat verum, et sic tollitur id quod est ad utrumlibet, quia, si esset aliquid ad utrumlibet, similiter se haberet ad hoc quod fieret vel non fieret, et non magis ad unum quam ad alterum.
Then he manifests how it follows from the foregoing hypothesis that nothing is indeterminate to either of two alternatives when he adds that if every affirmation or negation is determinately true, then either the one who affirms or the one who denies must be speaking the truth. That which is indeterminate to either of two alternatives is therefore destroyed, for if there is something indeterminate to either of two, it would be related alike to taking place or not taking place, and no more to one than to the other.
Peri.L13
Est autem considerandum quod Philosophus non excludit hic expresse contingens quod est ut in pluribus,
It should be noted that the Philosopher is not expressly excluding the contingent that is for the most part.
Peri.L13
duplici ratione:
There are two reasons for this.
Peri.L13
primo quidem quia tale contingens non excludit quin altera oppositarum enuntiationum determinate sit vera et alia falsa, ut dictum est;
In the first place, this kind of contingency still excludes the determinate truth of one of the opposite enunciations and the falsity of the other, as has been said.
Peri.L13
secundo quia, remoto contingenti quod est in paucioribus, quod a casu accidit, removetur per consequens contingens quod est ut in pluribus: in hoc enim differt id quod est in pluribus ab eo quod est semper et ex necessitate, quod deficit in minori parte.
Second, when the contingent that is infrequent (namely, that which takes place by chance) is removed, the contingent that is for the most part is removed as a consequence, for there is no difference between that which is for the most part and that which is infrequent except that the former fails for the least part.
Peri.L13
173. Deinde cum dicit: Amplius, si est album et cetera, ponit secundam rationem ad ostendendum praedictam dissimilitudinem, ducendo ad impossibile.
When he says: furthermore, on such a supposition (18b9), he gives a second argument to show the dissimilarity of enunciations about future singulars.
Peri.L13
Si enim similiter se habet veritas et falsitas in praesentibus et futuris, sequitur ut quidquid est verum de praesenti, antea verum fuerit de futuro eo modo quo est verum de praesenti; sed determinate nunc est verum dicere de aliquo singulari quod est album; ergo primo, id est ante quam illud fieret album, erat verum dicere quoniam hoc erit album. Sed eadem ratio videtur esse in propinquo et remoto; ergo, si ante unum diem verum fuit dicere quod hoc erit album, sequitur quod semper verum fuit dicere de quolibet eorum quae iam facta sunt, quod erit; si autem semper est verum dicere de praesenti quoniam est vel de futuro quoniam erit, non potest hoc non esse vel non futurum esse.
This argument is by reduction to the impossible. If truth and falsity are related in like manner in present and in future enunciations, it follows that whatever is true of the present was also true of the future, in the way in which it is true of the present. But it is now determinately true to say of some singular that it is white; therefore, formerly, before it became white, it was true to say that this will be white. Now, the same reasoning seems to hold for the proximate and the remote. Therefore, if yesterday it was true to say that this will be white, it follows that it was always true to say of anything that has taken place that it will be. And if it is always true to say of the present that it is, or of the future that it will be, it is not possible that this not be, or that it will not be.
Peri.L13
Cuius consequentiae ratio patet, quia ista duo sunt incompossibilia, quod aliquid vere dicatur et quod non sit; nam hoc includitur in significatione veri ut sit id quod dicitur; si ergo ponitur verum esse id quod dicitur de praesenti vel de futuro, non potest esse quin illud sit praesens vel futurum.
The reason for this consequence is evident, for these two cannot stand together: that something truly be said to be, and that it not be. For this is included in the signification of the true: that which is said, is. If, therefore, that which is said concerning the present or the future is posited to be true, it is not possible that this not be in the present or future.
Peri.L13
Sed quod non potest non fieri [impossibile], idem significat cum eo quod est impossibile non fieri, et quod impossibile est non fieri idem significat cum eo quod est necesse est fieri, ut in II plenius dicetur; sequitur ergo ex praemissis quod omnia quae futura sunt necesse est fieri. Ex quo sequitur ulterius quod nihil sit neque ad utrumlibet neque casu, quia illud quod accidit casu, non est ex necessitate, sed ut in paucioribus. Hoc autem relinquit pro inconvenienti; ergo primum est falsum, scilicet quod omne quod verum est esse, verum fuit determinate dicere esse futurum.
But that which cannot not take place signifies the same thing as that which is impossible not to take place. And that which is impossible not to take place signifies the same thing as that which necessarily takes place, as will be explained more fully in the second book. It follows, therefore, that all things that are future must necessarily take place. From this, it follows further that there is nothing that is indeterminate to either of two or that takes place by chance, for what happens by chance does not take place of necessity, but happens infrequently. But this is unlikely. Therefore, the first proposition is false—namely, that of everything of which it is true that it is—it was determinately true to say that it would be.
Peri.L13
174. Ad cuius evidentiam considerandum est quod, cum ‘verum’ hoc significet ut dicatur aliquid esse quod est, hoc modo est aliquid verum quo habet esse; cum autem aliquid est in praesenti, habet esse in se ipso, et ideo vere potest dici de eo quod est; sed quamdiu aliquid est futurum, nondum est in se ipso, est <tamen> aliqualiter in sua causa.
For clarification of this point, we must consider the following. Since “true” signifies that something is said to be what it is, something is true in the manner in which it has being. Now, when something is in the present, it exists in itself, and hence it can be truly said of it that it is. But as long as something is future, it does not yet exist in itself, but it is in a certain way in its cause.
Peri.L13
Quod quidem contingit tripliciter:
This is in a threefold way.
Peri.L13
uno modo, ut sic sit in sua causa ut ex necessitate ex ea proveniat, et tunc determinate habet esse in sua causa, unde determinate potest dici de eo quod erit;
It may be in its cause in such a way that it comes from it necessarily. In this case it has being determinately in its cause, and therefore it can be determinately said of it that it will be.
Peri.L13
alio modo est aliquid in sua causa ut quae habet inclinationem ad suum effectum, quae tamen impediri potest, unde et hoc determinatum est in sua causa, sed mutabiliter, et sic de hoc vere dici potest: ‘Hoc erit’, sed non per omnimodam certitudinem;
In another way, something is in its cause as it has an inclination to its effect, but can be impeded. This, then, is determined in its cause, but changeably, and hence it can be truly said of it that it will be, but not with complete certainty.
Peri.L13
aliquid autem est in sua causa pure in potentia, quae non magis est determinata ad unum quam ad alterum, unde relinquitur quod nullo modo potest determinate de aliquo eorum dici quod sit futurum, sed quod sit vel non sit.
Third, something is in its cause purely in potency. This is the case in which the cause is not yet determined more to one thing than to another; consequently, it cannot in any way be said determinately of these that it is going to be, but that it is or is not going to be.
Peri.L13
175. Deinde cum dicit: At vero nec quoniam et cetera, ostendit quod veritas non omnino deest in singularibus futuris utrique oppositorum.
Then he says: but still it is not possible to say that neither is true (18b17). Here he shows that truth is not altogether lacking to both of the opposites in singular future enunciations.
Peri.L13
Et primo proponit quod intendit, dicens quod, sicut non est verum dicere quod in talibus alterum oppositorum sit verum <determinate, sic non contingit dicere quod neutrum sit verum>, ut si dicamus quod, neque erit neque non erit.
First, he says that just as it is not true to say that in such enunciations one of the opposites is determinately true, so it is not true to say that neither is true—as if we could say that a thing neither will take place nor will not take place.
Peri.L13
Secundo ibi: Primum enim et cetera, probat propositum duabus rationibus.
Then when he says: in the first place, though the affirmation be false (18b18), he gives two arguments to prove his point.
Peri.L13
Quarum prima talis est: Affirmatio et negatio dividunt verum et falsum (quod patet ex definitione veri et falsi: nam nihil aliud est verum quam esse quod est vel non esse quod non est, et nihil aliud est falsum quam esse quod non est vel non esse quod est), et sic oportet quod, si affirmatio sit falsa, quod negatio sit vera, et e converso; sed, secundum praedictam positionem, affirmatio est falsa, qua dicitur: ‘Hoc erit’, nec tamen negatio erit vera; et similiter negatio erit falsa, affirmatione non existente vera; ergo praedicta positio est impossibilis, scilicet quod veritas desit utrique oppositorum.
The first is as follows. Affirmation and negation divide the true and the false. (This is evident from the definition of true and false, for to be true is to be what in fact is, or not to be what in fact is not; and to be false is to be what in fact is not, or not to be what in fact is.) Consequently, if the affirmation is false, the negation must be true, and conversely. But if the position is taken that neither is true, the affirmation “this will be” is false, yet the negation is not true; likewise, the negation will be false and the affirmation not be true. Therefore, the aforesaid position is impossible, namely, that truth is lacking to both of the opposites.
Peri.L13
Secundam rationem ponit ibi: Adhuc si verum et cetera.
The second argument begins at: second, if it is true to say that a thing is white and large (18b20).
Peri.L13
Quae talis est: Si verum est dicere aliquid, sequitur quod illud sit: puta, si verum est dicere quod aliquid sit magnum et album, sequitur utraque esse; et ita de futuro sicut de praesenti: sequitur enim esse cras, si verum est dicere quod erit cras; ergo, si vera est praedicta positio dicens quod neque cras erit neque non erit, oportebit neque fieri neque non fieri, quod est contra rationem eius quod est ad utrumlibet, quia quod est ad utrumlibet se habet ad alterum, ut navale bellum. Et ita ex hoc sequitur idem inconveniens quod ex praemissis.
The argument is as follows. If it is true to say something, it follows that it is. For example, if it is true to say that something is large and white, it follows that it is both. And this is so of the future as of the present, for if it is true to say that it will be tomorrow, it follows that it will be tomorrow. Therefore, if the position that it neither will be or not be tomorrow is true, it will be necessary that it neither happen nor not happen, which is contrary to the nature of that which is indeterminate to either of two, for that which is indeterminate to either of two is related to either; for example, a naval battle will take place tomorrow, or will not. The same unlikely things follow, then, from this as from the first argument.
Peri.L13
L. 14 (Α.9, 18b26–19a22)Contingency in things and the roots of contingency in relation to singular propositions about the future in contingent matter
Iterum de propositionibus singularibus de futuro in materia contingenti de contingentia in rebus deque contingentiae radicibus
Contingency in things and the roots of contingency in relation to singular propositions about the future in contingent matter
Peri.L14
18b26. Quae ergo contingunt inconvenientia haec sunt et huiusmodi alia, si omnis affirmationis et negationis vel in his quae in universalibus dicuntur universaliter vel in his quae sunt singularia, necesse est oppositarum hanc esse veram, illam vero falsam, nihil autem utrumlibet esse in his quae fiunt, sed omnia esse vel fieri ex necessitate.
18b26. These absurd consequences and others like them result if one of the opposites must be true and the other false in every affirmation and negation (whether in regard to universals taken universally or in regard to singulars). One is that nothing is indeterminate to either of two in things that come about, but all are and take place of necessity.
Peri.L14
Quare non oportebit neque consiliari neque negotiari, quoniam, si hoc facimus, erit hoc, si vero hoc, non erit.
Consequently, there will be no need to deliberate nor to take pains about something, as though if we were to do this, such a thing would follow, and if we were not to do this, it would not follow.
Peri.L14
18b33. Nihil enim prohibet in millesimum annum hunc quidem dicere hoc futurum esse, hunc vero non dicere, quare ex necessitate erit quodlibet eorum verum erat dicere tunc.
18b33. For nothing prevents one person from saying that this will be so in ten thousand years and another person saying it will not. On the aforesaid supposition, whichever of these was truly said at that time will take place of necessity.
Peri.L14
18b36. At vero nec hoc differt si aliquis dixerit negationem vel non dixerit; manifestum est enim quod sic se habeat res vel si hic quidem affirmaverit, ille vero negaverit: non enim propter affirmare vel negare erit vel non erit, nec in millesimum annum magis quam in quantolibet tempore. Quare si in omni tempore sic se habebat ut unum vere diceretur, necesse esset hoc fieri, et unumquodque eorum quae fiunt sic se habere ut ex necessitate fieret.
18b36. Moreover, it makes no difference whether people have actually made the contradictory statements or not; for it is evident that things either will take place or will not even if one person has not affirmed and the other denied it. For it is not because of the affirming or denying that it will be or will not be, whether in ten thousand years or any other space of time.
Peri.L14
Quando enim vere dicit quis quoniam erit, non potest non fieri; et quod factum est, verum erat dicere semper quoniam erit.
Therefore, if one thing or the other was always truly said, this would have to take place; and of every one of the things that takes place, it was always true that it had to take place. For what anyone truly says will be cannot not take place; and of that which takes place, it was always true to say that it would be.
Peri.L14
19a7. Quod si non haec possibilia sunt, videmur enim esse principium futurorum et ab eo quod consiliamur atque agimus aliquid.
19a7. But these things appear to be impossible, for we see that both our deliberation about doing something and our action are principles of future events.
Peri.L14
19a9. Et quoniam est omnino in his quae non semper actu sunt esse possibile et non, in quibus utrumque contingit esse et non esse, quare et fieri et non fieri.
19a9. And we see that universally in the things not always in act there is a potentiality to be and not to be. In these, there is the possibility either of being or not being, and so they may either take place or not take place.
Peri.L14
19a12. Et multa nobis manifesta sunt sic se habentia, ut quoniam hanc vestem possibile est incidi et non incidetur, sed prius exteritur; similiter autem et non incidi possibile est: non enim esset eam prius exteri nisi esset possibile non incidi. Quare et in aliis futuris quae secundum potentiam dicuntur huiusmodi, manifestum est quoniam non omnia ex necessitate vel sunt vel fiunt, sed alia quidem utrumlibet et non magis vel affirmatio vel negatio, alia vero magis quidem in pluribus alterum, sed contingit fieri et alterum, alterum vero minime.
19a12. We can point to many clear instances of this. For example, this cloak could be cut in half, and yet might not be but wear out first; likewise it is possible that it not be cut in half, for it could not wear out first if it were not possible that it not be cut. So it is, too, in other things that are said to take place according to this kind of potentiality. It is evident, then, that not all things are or take place of necessity, but some are indeterminate to either of two, in which case the affirmation is no more true than the negation; others take place more in one way than another, as in that which takes place for the most part, and yet it is possible for the other one to take place and the more frequent one not.
Peri.L14
176. Quae ergo continguunt inconvenientia et cetera. Ostenderat superius Philosophus, ducendo ad inconveniens, quod non est similiter verum vel falsum determinate in altero oppositorum in singularibus et futuris, sicut supra de aliis enuntiationibus dixerat; nunc autem ostendit inconvenientia ad quae duxerat esse impossibilia.
These absurd consequences and others like them. The Philosopher has shown, by leading the opposite position to what is unlikely, that in singular future enunciations truth or falsity is not determinately in one of the opposites, as it is in other enunciations. Now, he is going to show that the unlikely things to which it has led are impossibilities.
Peri.L14
Et circa hoc duo facit:
And about this he does two things:
Peri.L14
primo ostendit esse impossibilia ea quae sequebantur;
first, he shows that the things that followed are impossibilities;
Peri.L14
secundo concludit quomodo circa haec se veritas habeat, ibi: Igitur esse quod est et cetera.
second, he concludes what the truth is, where he says: now that which is, when it is, necessarily is (19a23; [200]).
Peri.L14
177. Circa primum tria facit:
About the first he does three things:
Peri.L14
primo proponit inconvenientia quae sequuntur;
first, he states the unlikely things that follow from the opposite position;
Peri.L14
secundo ostendit haec inconvenientia ex praedicta positione sequi, ibi: Nihil enim prohibet et cetera;
second, he shows that these follow from the aforesaid position, at: for nothing prevents one person (18b33; [178]);
Peri.L14
tertio ostendit esse impossibilia inconvenientia memorata, ibi: Quod si non haec possibilia sunt et cetera.
third, he shows that these are impossibilities where he says: but these things appear to be impossible (19a7; [180]).
Peri.L14
Dicit ergo primo, ex praemissis rationibus concludens, quod haec inconvenientia sequuntur si ponatur quod necesse sit oppositarum enuntiationum alteram determinate esse veram et alteram falsam, similiter in singularibus sicut in universalibus, quod scilicet nihil in his quae fiunt sit ad utrumlibet, sed omnia sint et fiant ex necessitate.
He says, then (18b26), concluding from the preceding reasoning, that these unlikely things follow, if the position is taken that of opposed enunciations one of the two must be determinately true and the other false in the same way in singular as in universal enunciations, namely, that in things that come about nothing is indeterminate to either of two, but all things are and take place of necessity.
Peri.L14
Et ex hoc ulterius inducit alia duo inconvenientia,
From this he infers two other unfitting things that follow.
Peri.L14
quorum primum est quod non oportebit de aliquo consiliari: probatum est enim in III Ethicorum quod consilium non est de his quae sunt ex necessitate, sed solum de contingentibus, quae possunt esse et non esse;
First, that it will not be necessary to deliberate about anything; but he proved in Ethics 3.3, 1112a19, that counsel is not concerned with things that take place necessarily, but only with contingent things, that is, things which can be or not be.
Peri.L14
secundum inconveniens est quod omnes actiones humanae quae sunt propter aliquem finem, puta negotiatio, quae est propter divitias acquirendas, erunt superfluae, quia, si omnia ex necessitate eveniunt, sive operemur sive non operemur, erit id quod intendimus. Sed hoc est contra intentionem hominum, qui ea intentione videntur consiliari et negotiari ut, si hoc faciant, erit talis finis, si autem faciant aliquid aliud, erit alius finis.
Second, that all human actions that are for the sake of some end (such as a business transaction to acquire riches) will be superfluous, because if all things come about of necessity, what we intend will take place whether we work to bring it about or not. This, however, is in opposition to the intention of men, for they seem to deliberate and to transact business with the intention that if they do, there will be such a result, but if they do something else, there will be another result.
Peri.L14
178. Deinde cum dicit: Nihil enim prohibet et cetera, probat quod dicta inconvenientia consequantur ex dicta positione.
Where he says: for nothing prevents one person from saying (18b33), he proves that the said unlikely things follow from the said position.
Peri.L14
Et circa hoc duo facit:
About this he does two things:
Peri.L14
primo ostendit praedicta inconvenientia sequi, quodam possibili posito;
first, he shows that the unlikely things follow from the positing of a certain possibility;
Peri.L14
secundo ostendit quod eadem inconvenientia sequuntur etiam si illud non ponatur, ibi: At <vero> nec hoc differt et cetera.
second, he shows that the same unlikely things follow even if that possibility is not posited, at: moreover, it makes no difference whether people (18b36; [179]).
Peri.L14
Dicit ergo primo non esse impossibile quod ante mille annos, quando nihil apud homines erat praecogitatum vel praeordinatum de his quae nunc aguntur, unus dixerit quod hoc <erit>, puta quod civitas talis subverteretur, alius autem dixerit quod hoc non erit; sed, si omnis affirmatio vel negatio determinate est vera, necesse est quod alter eorum determinate verum dixerit; ergo necesse fuit alterum eorum ex necessitate evenire; et eadem ratio est in omnibus aliis; ergo omnia ex necessitate eveniunt.
He says, then, that it is not impossible that a thousand years before, when men neither knew nor ordained any of the things that are taking place now, a man said, “This will be” (for example, that such a state would be overthrown), and another man said, “This will not be.” But if every affirmation or negation is determinately true, one of them must have spoken the truth. Therefore, one of them had to take place of necessity. This same reasoning holds for all other things. Therefore, everything takes place of necessity.
Peri.L14
179. Deinde cum dicit: At vero nec hoc differt et cetera, ostendit quod idem sequitur si illud possibile non ponatur.
Then he shows that the same thing follows if this possibility is not posited, at: moreover, it makes no difference whether people (18b36).
Peri.L14
Nihil enim differt, quantum ad rerum existentiam vel eventum, si, uno affirmante hoc esse futurum, alius negaverit vel non negaverit; ita enim se habebit res si hoc factum fuerit sicut si hoc non factum fuerit: non enim propter nostrum affirmare vel negare mutatur cursus rerum ut sit aliquid vel non sit, quia veritas nostrae enuntiationis non est causa existentiae rerum, sed potius e converso; similiter etiam non differt quantum ad eventum eius quod nunc agitur, utrum fuerit affirmatum vel negatum ante millesimum annum vel ante quodcumque tempus. Sic ergo, si in quocumque tempore praeterito ita se habebat veritas enuntiationum ut necesse esset quod alterum oppositorum vere diceretur, et ad hoc quod necesse est aliquid vere dici sequitur quod necesse sit illud esse vel fieri, consequens est quod unumquodque eorum quae fiunt sic se habeat ut ex necessitate fiat.
It makes no difference in relation to the existence or outcome of things whether or not a person denies that this is going to take place when it is affirmed, for (as was previously said) the event will either take place or not whether the affirmation and denial have been made or not. That something is or is not does not result from a change in the course of things to correspond to our affirmation or denial, for the truth of our enunciation is not the cause of the existence of things, but rather the converse. Nor does it make any difference to the outcome of what is now being done whether it was affirmed or denied a thousand years before, or at any other time before. Therefore, if in all past time, the truth of enunciations was such that one of the opposites had to have been truly said, and if upon the necessity of something being truly said it follows that this must be or take place, it will follow that everything that takes place is such that it takes place of necessity.
Peri.L14
Et huius consequentiae rationem assignat per hoc quod, si ponatur aliquem vere dicere quod hoc erit, non potest non futurum esse (sicut, supposito quod sit homo, non potest non esse animal rationale mortale: hoc enim significatur cum dicitur aliquid vere dici, scilicet quod ita sit ut dicitur); eadem autem habitudo est eorum quae nunc dicuntur ad ea quae futura sunt, quae erat eorum quae prius dicebantur ad ea quae sunt praesentia vel praeterita; et ita omnia ex necessitate acciderunt et accidunt et accident, quia quod nunc factum est, utpote in praesenti vel praeterito existens, semper verum erat dicere quoniam erit futurum.
The reason he assigns for this consequence is the following. If it is posited that someone truly says this will be, it is not possible that it will not be, just as once we suppose that man exists, he cannot not be a rational mortal animal. For to be truly said means that it is such as is said. Moreover, the relationship of what is said now to what will be is the same as the relationship of what was said previously to what is in the present or the past. Therefore, all things have necessarily happened, and they are necessarily happening, and they will necessarily happen, for of what is accomplished now, as existing in the present or in the past, it was always true to say that it would be.
Peri.L14
180. Deinde cum dicit: Quod si non haec possibilia sunt et cetera, ostendit praedicta esse impossibilia.
When he says: but these things appear to be impossible (19a7), he shows that what has been said is impossible.
Peri.L14
Et primo per rationem;
First, he shows this by reason;
Peri.L14
secundo per exempla sensibilia, ibi: Et multa nobis manifesta sunt, et cetera.
second, by sensible examples, at: we can point to many clear instances of this (19a12; [182]).
Peri.L14
Circa primum duo facit:
He does two things about the first:
Peri.L14
primo ostendit propositum in rebus humanis;
first, he shows it through human affairs;
Peri.L14
secundo etiam in aliis rebus, ibi: <Et> quoniam est omnino, et cetera.
second, also in other things, at: and we see that universally in the things (19a9; [181]).
Peri.L14
Quantum autem ad res humanas, ostendit esse impossibilia quae dicta sunt, per hoc quod homo manifeste videtur esse principium quorumdam futurorum, quae agit quasi dominus existens suorum actuum et in sua potestate habens agere vel non agere. Quod quidem principium si removeatur, tollitur totus ordo conversationis humanae et omnia principia philosophiae moralis: hoc enim sublato, non erit aliqua utilitas persuasionis nec comminationis nec punitionis aut remunerationis, quibus homines alliciuntur ad bona et retrahuntur a malis, et sic evacuatur tota civilis scientia. Hoc ergo Philosophus accipit pro principio manifesto, quod homo sit principium futurorum; non est autem futurorum principium nisi per hoc quod consiliatur et facit aliquid: ea enim quae agunt absque consilio non habent dominium sui actus, quasi libere iudicantes de his quae sunt agenda, sed quodam naturali instinctu moventur ad agendum, ut patet in animalibus brutis. Unde impossibile est quod supra conclusum est, quod non oporteat nos agere vel consiliari, et sic etiam impossibile est illud ex quo sequebatur, scilicet quod omnia ex necessitate eveniant.
First, he argues that the position taken is impossible in relation to human affairs, for clearly man seems to be the principle of the future things that he does insofar as he is the master of his own actions and has the power to act or not to act. Indeed, to reject this principle would be to do away with the whole order of human association and all the principles of moral philosophy. For men are attracted to good and withdrawn from evil by persuasion and threat, and by punishment and reward; but rejection of this principle would make these useless and thus nullify the whole of civil science. Here the Philosopher accepts it as an evident principle that man is the principle of future things. However, he is not the principle of future things unless he deliberates about a thing and then does it. In those things that men do without deliberation, they do not have dominion over their acts—that is, they do not judge freely about things to be done, but are moved to act by a kind of natural instinct such as is evident in the case of brute animals. Hence, the conclusion that it is not necessary for us to take pains about something or to deliberate is impossible; likewise, what it followed from is impossible, namely, that all things take place of necessity.
Peri.L14
181. Deinde cum dicit: Et quoniam est omnino et cetera, ostendit idem etiam in aliis rebus.
Then he shows that this is also the case in other things, at: and we see that universally in the things (19a9).
Peri.L14
Manifestum est enim etiam in rebus naturalibus esse quaedam quae non semper actu sunt; ergo in eis contingit esse et non esse: alioquin vel semper essent vel semper non essent; id autem quod non est, incipit esse aliquid per hoc quod fit illud, sicut id quod non est album, incipit esse album per hoc quod fit album, si autem non fiat album, permanet non ens album; ergo in quibus contingit esse et non esse, contingit etiam fieri et non fieri; non ergo talia ex necessitate sunt vel fiunt, sed est in eis natura possibilitatis, per quam se habent ad fieri et non fieri, esse et non esse.
In natural things, too, it is evident that there are some things not always in act; it is therefore possible for them to be or not be, otherwise they would either always be or always not be. Now, that which is not begins to be something by becoming it, as, for example, that which is not white begins to be white by becoming white. But if it does not become white, it continues not to be white. Therefore, in things that have the possibility of being and not being, there is also the possibility of becoming and not becoming. Such things neither are nor come to be of necessity, but there is in them the kind of possibility which disposes them to becoming and not becoming, to being and not being.
Peri.L14
182. Deinde cum dicit: Et multa nobis manifesta sunt et cetera, ostendit propositum per sensibilia exempla.
Next, he shows the impossibility of what was said by examples perceptible to the senses, at: we can point to many clear instances of this (19a12).
Peri.L14
Sit enim una vestis nova: manifestum est quod eam possibile est incidi, quia nihil obviat incisioni nec ex parte agentis nec ex parte patientis; probat autem quod simul cum hoc quod est possibile eam incidi, possibile est eam non incidi, eodem modo quo supra probavit duas indefinitas oppositas esse simul veras, scilicet per assumptionem contrarii: sicut enim possibile est istam vestem incidi, ita possibile est eam exteri, id est vetustate corrumpi; sed, si exteritur, non inciditur; ergo utrumque possibile est, scilicet eam incidi et non incidi. Et ex hoc universaliter concludit quod in aliis futuris, quae non semper sunt in actu, sed sunt in potentia, hoc manifestum est quod non omnia ex necessitate sunt vel fiunt, sed eorum quaedam sunt ad utrumlibet, quae non se habent magis ad affirmationem vel negationem; alia vero sunt in quibus alterum eorum contingit ut in pluribus, sed tamen contingit etiam ut in paucioribus quod altera pars sit vera et non alia, quae scilicet contingit ut in pluribus.
Take a new garment, for example. It is evident that it is possible to cut it, for nothing stands in the way of cutting it, either on the part of the agent or the patient. He proves it is at once possible that it be cut and that it not be cut in the same way he has already proved that two opposed indefinite enunciations are at once true—that is, by the assumption of contraries. Just as it is possible that the garment be cut, so it is possible that it wear out, that is, be corrupted in the course of time. But if it wears out, it is not cut. Therefore, both are possible, namely, that it be cut and that it not be cut. From this he concludes universally in regard to other future things which are not always in act, but are in potency, that not all are or take place of necessity; some are indeterminate to either of two, and therefore are not related any more to affirmation than to negation; there are others in which one possibility happens for the most part, although it is possible, but for the least part, that the other part be true, and not the part which happens for the most part.
Peri.L14
183. Est autem hic considerandum quod, sicut Boethius dicit hic in Commento, circa possibile et necessarium diversimode aliqui sunt opinati.
With regard to this question about the possible and the necessary, there have been different opinions, as Boethius says in his Commentary, and these will have to be considered.
Peri.L14
Quidam enim distinxerunt ea secundum eventum, sicut Diodorus, qui dixit illud esse impossibile quod nunquam erit, necessarium vero quod semper erit, possibile vero quod quandoque erit, quandoque non erit.
Some who distinguished them according to result, such as Diodorus, said that the impossible is that which never will be; the necessary, that which always will be; and the possible, that which sometimes will be, sometimes not.
Peri.L14
Stoici vero distinxerunt haec secundum exteriora prohibentia: dixerunt enim necessarium esse illud quod non potest prohiberi quin sit verum, impossibile vero quod semper prohibetur a veritate, possibile vero quod potest prohiberi vel non prohiberi.
The Stoics distinguished them according to exterior restraints. They said the necessary was that which could not be prevented from being true; the impossible, that which is always prevented from being true; and the possible, that which can be prevented or not be prevented.
Peri.L14
Utraque autem distinctio videtur esse incompetens. Nam prima distinctio est a posteriori: non enim ideo aliquid est necessarium quia semper erit, sed potius ideo semper erit quia est necessarium; et idem patet in aliis.
However, the distinctions in both of those cases seem to be inadequate. The first distinctions are a posteriori, for something is not necessary because it always will be, but rather, it always will be because it is necessary. This holds for the possible as well as the impossible.
Peri.L14
Secunda autem assignatio est ab exteriori et quasi per accidens: non enim ideo aliquid est necessarium quia non habet impedimentum, sed quia est necessarium, ideo impedimentum habere non potest.
The second designation is taken from what is external and accidental, for something is not necessary because it does not have an impediment, but it does not have an impediment because it is necessary.
Peri.L14
Et ideo alii melius ista distinxerunt secundum naturam rerum, ut scilicet illud dicatur necessarium quod in sua natura determinatum est solum ad esse, impossibile autem quod est determinatum solum ad non esse, possibile autem quod ad neutrum est omnino determinatum, sive se habeat magis ad unum quam ad alterum, sive se habeat aequaliter ad utrumque, quod dicitur contingens ad utrumlibet. Et hoc quidem Boethius attribuit Philoni, sed manifeste haec est sententia Aristotelis in hoc loco: assignat enim rationem possibilitatis et contingentiae, in his quidem quae sunt a nobis ex eo quod sumus consiliativi, in aliis autem ex eo quod materia est in potentia ad utrumque oppositorum.
Others distinguished these better by basing their distinction on the nature of things. They said that the necessary is that which in its nature is determined only to being; the impossible, that which is determined only to non-being; and the possible, that which is not altogether determined to either, whether related more to one than to another or related equally to both. The latter is known as that which is indeterminate to either of two. Boethius attributes these distinctions to Philo. However, this is clearly the opinion of Aristotle here, for he gives as the reason for the possibility and contingency in the things we do the fact that we deliberate, and in other things the fact that matter is in potency to either it of two opposites.
Peri.L14
184. Sed videtur ratio haec non esse sufficiens: sicut enim in corporibus corruptibilibus materia invenitur in potentia se habens ad esse et non esse, ita etiam in corporibus caelestibus invenitur potentia ad diversa ubi, et tamen nihil in eis evenit contingenter, sed solum ex necessitate.
But this reasoning does not seem to be adequate either. While it is true that in corruptible bodies matter is in potency to being and non-being, and in celestial bodies there is potency to diverse location, nevertheless, nothing happens contingently in celestial bodies, but only of necessity.
Peri.L14
Unde dicendum est quod possibilitas materiae ad utrumque, si communiter loquamur, non est sufficiens ratio contingentiae, nisi etiam addatur ex parte potentiae activae quod non sit omnino determinata ad unum; alioquin, si ita sit determinata ad unum quod impediri non possit, consequens est quod ex necessitate reducat in actum potentiam, scilicet passivam, eodem modo.
Consequently, we have to say that the potentiality of matter to either of two possibilities, if we are speaking generally, does not suffice as a reason for contingency unless we add on the part of the active potency that it is not wholly determined to one. For if it is so determined to one that it cannot be impeded, it follows that it necessarily reduces into act the passive potency in the same mode.
Peri.L14
185. Hoc igitur quidam attendentes posuerunt quod potentia quae est in ipsis rebus naturalibus sortitur necessitatem ex aliqua causa determinante ad unum, quam dixerunt fatum.
Considering this, some maintained that the very potency which is in natural things receives necessity from some cause determined to one. This cause they called “fate.”
Peri.L14
Quorum Stoici posuerunt fatum in quadam serie sive connexione causarum, supponentes quod omne quod in mundo accidit habet causam, causa autem posita necesse est effectum poni et, si una causa per se non sufficit, multae causae ad hoc concurrentes accipiunt rationem unius causae sufficientis; et ita concludebant quod omnia ex necessitate eveniunt.
The Stoics, for example, held that fate was to be found in a series or interconnection of causes, on the assumption that everything that happens has a cause. But when a cause has been posited, the effect is posited of necessity, and if one cause does not suffice in itself, many causes concurring for this take on the nature of one sufficient cause. So, they concluded, everything happens of necessity.
Peri.L14
186. Sed hanc rationem solvit Aristoteles in VI Metaphysicae, interimens utramque propositionum assumptarum. Dicit enim quod non omne quod fit habet causam, sed solum illud quod est per se; sed id quod est per accidens non habet causam, quia proprie non est ens, sed magis ordinatur cum non ente, ut etiam Plato dixit; unde ‘esse musicum’ habet causam, et similiter ‘esse album’, sed hoc quod est ‘album esse musicum’ non habet causam; et idem est in omnibus aliis huiusmodi. Similiter etiam haec est falsa, quod causa posita, etiam sufficienti, necesse sit effectum poni: non enim omnis causa est talis, etiam si sit sufficiens, cuius effectus impediri non possit; sicut ignis est sufficiens causa combustionis lignorum, sed tamen per effusionem aquae impeditur combustio.
Aristotle refutes this reasoning in Metaphysics 6.2, 1026a33, by destroying each of the assumed propositions. He says there that not everything that takes place has a cause, but only what is in itself has a cause. What is accidental does not have a cause, for it is not properly being but is more like non-being, as Plato also held. Hence, “to be musical” has a cause, and so does “to be white,” but “to be musical white” does not have a cause. The same is the case with all others of this kind. It is also false that when a cause has been posited—even a sufficient one—the effect must be posited, for not every cause (even if it is sufficient) is such that its effect cannot be impeded. For example, fire is a sufficient cause of the combustion of wood, but if water is poured on it, the combustion is impeded.
Peri.L14
187. Si autem utraque propositionum esset vera, infallibiliter sequeretur omnia ex necessitate contingere, quia, si quilibet effectus habet causam, esset effectum qui est futurus post quinque dies aut post quodcumque tempus, reducere in aliquam causam priorem, et sic inde quo usque esset devenire ad causam quae nunc est in praesenti vel iam fuit in praeterito; si autem, causa posita, necesse est effectum poni, per ordinem causarum deveniet necessitas usque ad ultimum effectum. Puta: ‘Si comedit salsa, sitiet; si sitiet, exibit domum ad bibendum; si exibit domum, occidetur a latronibus’; quia ergo iam comedit salsa, necesse est eum occidi.
However, if both of the aforesaid propositions were true, it would follow infallibly that everything happens necessarily. For if every effect has a cause, then it would be possible to reduce an effect (which is going to take place in five days or whatever time) to some prior cause, and to continue until it reaches a cause which is now in the present or already has been in the past. Moreover, if, when the cause is posited, the effect must be posited, the necessity would reach through an order of causes all the way to the ultimate effect. For instance, if someone eats salty food, he will be thirsty; if he is thirsty, he will go outside to drink; if he goes outside to drink, he will be killed by robbers. Therefore, once he has eaten salty food, it is necessary that he be killed.
Peri.L14
Et ideo Aristoteles ad hoc excludendum, ostendit utramque propositionum praedictarum esse falsam, ut dictum est.
To exclude this position, Aristotle shows that both of these propositions are false.
Peri.L14
188. Obiiciunt autem quidam contra hoc, quod omne per accidens reducitur ad aliquid per se, et ita oportet effectum qui est per accidens reduci in causam per se.
However, some persons object to this on the grounds that everything accidental is reduced to something in itself, and therefore an effect that is accidental must be reduced to a per se cause.
Peri.L14
Sed non attendunt quod id quod est per accidens reducitur ad per se in quantum accidit ei quod est per se, sicut musicum accidit Socrati et omne accidens alicui subiecto per se existenti; et similiter omne quod in aliquo effectu est per accidens consideratur circa aliquem effectum per se qui, quantum ad id quod per se est, habet causam per se, quantum autem ad id quod inest ei per accidens, non habet causam per se, sed causam per accidens: oportet enim effectum proportionaliter referre <ad causam suam>, ut in II Physicorum et in VI Methaphysicae dicitur.
Those who argue in this way fail to take into account that the accidental is reduced to the per se inasmuch as it is accidental to that which is in itself. For example, “musical” is accidental to Socrates, and every accident is accidental to some subject existing in itself. Similarly, everything accidental in some effect is considered in relation to some per se effect, which effect, in relation to that which is in itself, has a per se cause, but in relation to what is in it accidentally, does not have a per se cause but an accidental one. This is because the effect must be proportionately referred to its cause.1
Peri.L14
189. Quidam vero, non attendentes differentiam effectuum per accidens et per se, temptant reducere omnes effectus hic inferius provenientes in aliquam causam per se, quam ponebant esse virtutem caelestium corporum, in qua ponebant fatum, dicentes nihil aliud esse fatum quam ‘vim positionis siderum’.
Some, however, not considering the difference between accidental and per se effects, tried to reduce all the effects that come about in this world to some per se cause. They posited as this cause the power of the heavenly bodies and assumed fate to be dependent on this power—fate being, according to them, nothing else but the power of the position of the constellations.
Peri.L14
Sed ex hac causa non potest provenire necessitas in omnibus quae hic aguntur.
But such a cause cannot bring about necessity in all the things accomplished in this world.
Peri.L14
Multa enim hic fiunt ex intellectu et voluntate, quae per se et directe non subduntur virtuti caelestium corporum: cum enim intellectus sive ratio et voluntas non sint actus organi corporalis, ut probatur in libro De anima, impossibile est quod directe subdantur intellectus seu ratio et voluntas virtuti caelestium corporum; nulla enim vis corporalis potest agere per se nisi in rem corpoream. Vires autem sensitivae, in quantum sunt actus organorum corporalium, per accidens subduntur actioni caelestium corporum; unde Philosophus, in libro De anima, opinionem ponentium voluntatem hominis subiici motui caeli adscribit his qui non ponebant intellectum differre a sensu. Indirecte tamen vis caelestium corporum redundat ad intellectum et voluntatem, in quantum scilicet intellectus et voluntas utuntur viribus sensitivis; manifestum autem est quod passiones virium sensitivarum non inferunt necessitatem rationi et voluntati: nam continens habet pravas concupiscentias, sed ‘non deducitur’, ut patet per Philosophum in VII Ethicorum. Sic igitur ex virtute caelestium corporum non provenit necessitas in his quae per rationem et voluntatem fiunt.
For many things come about from intellect and will, which are not subject directly and in themselves to the power of the heavenly bodies. For the intellect (or reason) and the will (which is in reason) are not acts of a corporeal organ,1 and consequently cannot be directly subject to the power of the heavenly bodies, since a corporeal force, of itself, can only act on a corporeal thing. The sensitive powers, on the other hand, are accidentally subject to the action of the heavenly bodies inasmuch as they are acts of corporeal organs. Hence, the Philosopher2 ascribes the opinion that the will of man is subject to the movement of the heavens to those who hold the position that the intellect does not differ from sense. The power of the heavenly bodies, however, does indirectly redound to the intellect and will inasmuch as the agent intellect and will use the sensitive powers. But clearly the passions of the sensitive powers do not induce necessity of reason and will, for the continent man has wrong desires but is not seduced by them.3 Therefore, we may conclude that the power of the heavenly bodies does not bring about necessity in the things done through reason and will.
Peri.L14
Similiter etiam nec in aliis corporalibus effectibus rerum corruptibilium, in quibus multa per accidens eveniunt; id autem quod est per accidens non potest reduci sicut in causam per se in aliquam virtutem naturalem, quia virtus naturae se habet ad unum, quod autem est per accidens non est unum (unde et supra dictum est quod haec enuntiatio non est una: ‘Socrates albus musicus’, quia non significat unum); et ideo Philosophus dicit in libro De somno et vigilia quod multa, quorum signa praeexistunt in corporibus caelestibus, puta in imbribus et tempestatibus, non eveniunt, quia scilicet impediuntur per accidens. Et, quamvis illud etiam impedimentum secundum se consideratum reducatur in aliquam causam caelestem, tamen concursus horum, cum sit per accidens, non potest reduci in aliquam causam naturaliter agentem.
This is also the case in other corporeal effects of corruptible things, in which many things happen accidentally. What is accidental cannot be reduced to a per se cause in a natural power because the power of nature is directed to some one thing. But what is accidental is not one; hence it was said above that the enunciation “Socrates is a white musical being” is not one because it does not signify one thing. This is the reason the Philosopher says in the book On Sleep and Sleeplessness1 that many things of which the signs preexist in the heavenly bodies—for example, in storm clouds and tempests—do not take place because they are accidentally impeded. And although this impediment considered as such is reduced to some celestial cause, the concurrence of these, since it is accidental, cannot be reduced to a cause acting naturally.
Peri.L14
190. Sed considerandum est quod id quod est per accidens potest ab intellectu accipi ut unum, sicut album esse musicum, quod, quamvis secundum se non sit unum, tamen intellectus ut unum accipit, in quantum scilicet componendo format enuntiationem unam; et secundum hoc contingit id quod secundum se per accidens evenit et casualiter, reduci in aliquem intellectum praeordinantem; sicut concursus duorum servorum ad certum locum est per accidens et casualis quantum ad eos, cum unus eorum ignoret de alio; potest tamen esse per se intentus a domino, qui utrumque mittit ad hoc quod in certo loco sibi concurrant.
However, what is accidental can be taken as one by the intellect. For example, “the white is musical,” which as such is not one, the intellect takes as one (that is, insofar as it forms one enunciation by composing). In accordance with this, it is possible to reduce what happens accidentally and fortuitously in itself to a preordaining intellect. For example, the meeting of two servants at a certain place may be accidental and fortuitous with respect to them, since neither knew the other would be there, but be itself intended by their master, who sent each of them to encounter the other in a certain place.
Peri.L14
191. Et secundum hoc aliqui posuerunt omnia quaecumque in hoc mundo aguntur, <etiam> quae videntur fortuita vel casualia, reduci in ordinem providentiae divinae, ex qua dicebant dependere fatum. Et hoc quidem aliqui stulti negaverunt, iudicantes de intellectu divino ad modum intellectus nostri, qui singularia non cognoscit.
Accordingly, some have maintained that everything whatever that is effected in this world—even the things that seem fortuitous and casual—is reduced to the order of divine providence, on which they said fate depends. Other foolish men have denied this, judging of the divine intellect in the mode of our intellect, which does not know singulars.
Peri.L14
Hoc autem est falsum: nam intelligere Dei et velle eius est ipsum esse ipsius, unde, sicut esse eius sua virtute comprehendit omne illud quod quocumque modo est, in quantum scilicet est per participationem ipsius, ita etiam suum intelligere et suum intelligibile comprehendit omnem cognitionem et omne cognoscibile, et suum velle et suum volitum comprehendit omnem appetitum et omne appetibile quod est bonum, ut scilicet ex hoc ipso quod aliquid est cognoscibile cadat sub eius cognitione, et ex hoc ipso quod est bonum cadat sub eius voluntate, sicut ex ipso quod est ens aliquid cadit sub eius virtute activa, quam ipse perfecte comprehendit, cum sit per intellectum agens.
But the position of the latter is false, for his divine thinking and willing is his very being. Hence, just as his being by its power comprehends all that is in any way (that is, inasmuch as it is through participation of him) so also his thinking and what he thinks comprehend all knowing and everything knowable, and his willing and what he wills comprehend all desiring and every desirable good. In other words, whatever is knowable falls under his knowledge, and whatever is good falls under his will, just as whatever exists falls under his active power, which he comprehends perfectly, since he acts by his intellect.
Peri.L14
192. Sed, si providentia divina sit per se causa omnium quae in hoc mundo accidunt, saltem bonorum, videtur quod omnia ex necessitate accidant:
It may be objected, however, that if divine providence is the per se cause of everything that happens in this world—at least of good things—it would look as though everything takes place of necessity:
Peri.L14
primo quidem ex parte scientiae eius, non enim potest eius scientia falli et ita ea quae ipse scit, videtur quod necesse sit evenire;
first, on the part of his knowledge, for his knowledge cannot be fallible, and so it would seem that what he knows happens necessarily;
Peri.L14
secundo ex parte voluntatis: voluntas enim Dei inefficax esse non potest, videtur igitur quod omnia quae vult ex necessitate eveniant.
second, on the part of the will, for the will of God cannot be inefficacious; therefore, it would seem that everything He wills happens of necessity.
Peri.L14
193. Procedunt autem hae obiectiones ex eo quod cognitio divini intellectus et operatio divinae voluntatis pensantur ad modum eorum quae in nobis sunt, cum tamen multo dissimiliter se habeant.
These objections arise from judging of the cognition of the divine intellect and the operation of the divine will according to the way these are in us, when in reality they are very dissimilar.
Peri.L14
194. Nam primo quidem ex parte cognitionis vel scientiae considerandum est quod ad cognoscendum ea quae secundum ordinem temporis eveniunt, aliter se habet vis cognoscitiva quae sub ordine temporis aliqualiter continetur, aliter illa quae totaliter est extra ordinem temporis.
On the part of cognition or knowledge, it should be noted that in knowing things that take place according to the order of time, the cognitive power that is contained in any way under the order of time is related to them in another way than the cognitive power that is totally outside of the order of time.
Peri.L14
Cuius exemplum conveniens accipi potest ex ordine loci: nam secundum Philosophum in IV Physicorum, secundum prius et posterius in magnitudine est prius et posterius in motu et per consequens in tempore; si ergo sint multi homines per viam aliquam transeuntes, quilibet eorum qui sub ordine transeuntium continetur habet cognitionem de praecedentibus et succedentibus, in quantum sunt praecedentes et subsequentes, quod pertinet ad ordinem loci; et ideo quilibet eorum videt eos qui iuxta se sunt et aliquos eorum qui eos praecedunt, eos autem qui post se sunt videre non potest; si autem esset aliquis extra totum ordinem transeuntium, utpote in aliqua excelsa turri constitutus unde posset tota via videri, videret quidem simul omnes in via existentes, non sub ratione praecedentis vel subsequentis, in comparatione scilicet ad eius intuitum, sed simul omnes videret et quomodo unus eorum alium praecedit.
The order of place provides a suitable example of this. According to the Philosopher, 1 “before” and “after” in movement (and consequently in time) corresponds to “before” and “after” in magnitude. Therefore, if there are many men passing along some road, any one of those in the ranks has knowledge of those preceding and following as preceding and following, which pertains to the order of place. Hence any one of them sees those who are next to him and some of those who precede him, but he cannot see those who follow behind him. If, however, there were someone outside of the whole order of those passing along the road—for instance, stationed in some high tower where he could see the whole road—he would at once see all those who were on the road, not under the formality of preceding and following (that is, in relation to his view), but all at the same time, and how one precedes another.
Peri.L14
Quia igitur cognitio nostra cadit sub ordine temporis vel per se vel per accidens (unde et anima in componendo et dividendo necesse habet adiungere tempus, ut dicitur in III de anima), consequens est quod sub eius cognitione cadant res sub ratione praesentis, praeteriti et futuri; et ideo praesentia cognoscit tanquam actu existentia et sensu aliqualiter perceptibilia, praeterita autem cognoscit ut memorata, futura autem non cognoscit in se ipsis, quia nondum sunt, sed cognoscere ea potest in causis suis, per certitudinem quidem si totaliter in causis suis determinata sunt, ut ex quibus ex necessitate eveniant; per coniecturam autem si non sint sic determinata quin impediri possint, sicut quae sunt ut in pluribus; nullo autem modo, si in suis causis sunt omnino in potentia non magis determinata ad unum quam ad aliud, sicut quae sunt ad utrumlibet: non enim est aliquid cognoscibile secundum quod est in potentia, sed solum secundum quod est in actu, ut patet per Philosophum in IX Metaphysicae.
Now, our cognition falls under the order of time, either in itself or accidentally; thus, in composing and dividing, the soul necessarily includes time.1 Consequently, things are subject to our cognition under the aspect of present, past, and future. Hence the soul knows present things as existing in act and perceptible by sense in some way. It knows past things as remembered. It does not yet know future things in themselves because they do not yet exist, but it can know them in their causes. This it does with certitude if they are totally determined in their causes so that they will take place of necessity; by conjecture if they are not so determined that they cannot be impeded, as in the case of those things that are for the most part; and in no way if they are wholly in potency in their causes, namely, not more determined to one thing than to another, as in the case of those that are indeterminate to either of two. The reason for this is that a thing is not knowable according as it is in potency, but only according as it is in act, as the Philosopher.2
Peri.L14
195. Sed Deus est omnino extra ordinem temporis, quasi in arce aeternitatis constitutus, quae est tota simul, cui subiacet totus temporis decursus [secundum unum et simplicem eius intuitum] et ideo uno intuitu videt omnia quae aguntur secundum totum temporis decursum, unumquodque ut est in se ipso existens, non quasi sibi futurum quantum ad eius intuitum prout est in solo ordine suarum causarum (quamvis et ipsum ordinem causarum videat), sed omnino aeternaliter sic videt unumquodque eorum quae sunt in quocumque tempore, sicut oculus humanus videt Socratem sedere in se ipso, non in causa sua.
God, however, is wholly outside the order of time, stationed as though at the summit of eternity, which is wholly simultaneous, and to him the whole course of time is subjected in one simple intuition. For this reason, he sees in one glance everything that is effected in the evolution of time, and each thing as it is in itself, and it is not future to him in relation to his view as it is in the order of its causes alone (although he also sees the very order of the causes). But he sees each of the things that are in whatever time completely and eternally, as the human eye sees Socrates sitting, not in its causes, but in itself.
Peri.L14
196. Ex hoc autem quod homo videt Socratem sedere, non tollitur eius contingentia, quae respicit ordinem causae ad effectum, et tamen certissime et infallibiliter videt oculus hominis Socratem sedere dum sedet, quia unumquodque prout est in se ipso iam determinatum est. Sic igitur relinquitur quod Deus certissime et infallibiliter cognoscat omnia quae fiunt in tempore, et tamen ea quae in tempore eveniunt non sunt vel fiunt ex necessitate, sed contingenter.
Now, from the fact that man sees Socrates sitting, the contingency of his sitting (which concerns the order of cause to effect) is not destroyed, yet the eye of man most certainly and infallibly sees Socrates sitting while he is sitting, since each thing as it is in itself is already determined. Hence it follows that God knows all things that take place in time most certainly and infallibly, and yet the things that happen in time neither are now nor take place of necessity, but contingently.
Peri.L14
197. Similiter etiam ex parte voluntatis divinae differentia est attendenda. Nam voluntas divina est intelligenda ut extra ordinem entium existens, velut causa quaedam profundens totum ens et omnes eius differentias; sunt autem differentiae entis possibile et necessarium, et ideo ex ipsa voluntate divina originantur necessitas et contingentia in rebus, et distinctio utriusque secundum rationem proximarum causarum: ad effectus autem quos voluit necessarios esse disposuit causas necessarias, ad effectus autem quos voluit esse contingenter, ordinavit causas contingenter agentes, <id est> potentes deficere; et secundum harum conditionem causarum, effectus dicuntur vel necessarii vel contingentes, quamvis omnes dependeant a voluntate divina sicut a prima causa quae transcendit ordinem necessitatis et contingentiae. Hoc autem non potest dici de voluntate humana nec de aliqua alia causa, quia omnis alia causa cadit iam sub ordine necessitatis vel contingentiae, et ideo oportet quod vel ipsa causa possit deficere, vel quod effectus eius non sit contingens, sed necessarius. Voluntas autem divina indeficiens est, tamen non omnes effectus eius sunt necessarii, sed quidam contingentes.
There is likewise a difference to be noted on the part of the divine will, for the divine will must be understood as existing outside of the order of beings, as a cause producing the whole of being and all its differences. Now, the possible and the necessary are differences of being, and therefore necessity and contingency in things and the distinction of each according to the nature of their proximate causes originate from the divine will itself, for he disposes necessary causes for the effects that he wills to be necessary, and he ordains causes acting contingently (that is, able to fail) for the effects that he wills to be contingent. And according to the condition of these causes, effects are called either necessary or contingent, although all depend on the divine will as on a first cause, which transcends the order of necessity and contingency. This, however, cannot be said of the human will, nor of any other cause, for every other cause already falls under the order of necessity or contingency; hence, either the cause itself must be able to fail or, if not, its effect is not contingent, but necessary. The divine will, on the other hand, is unfailing, yet, nevertheless, not all its effects are necessary, but some are contingent.
Peri.L14
198. Similiter autem aliam radicem contingentiae quam hic Philosophus ponit, ex hoc quod sumus consiliativi, aliqui subvertere nituntur, volentes ostendere quod voluntas in eligendo ex necessitate movetur ab appetibili: cum enim bonum sit obiectum voluntatis, non potest, ut videtur, ab hoc divertere quin appetat illud quod sibi videtur bonum, sicut nec ratio potest ab hoc divertere quin assentiat ei quod sibi videtur verum; et ita videtur quod electio, consilium consequens, semper ex necessitate proveniat, et sic omnia quorum nos sumus principium per consilium et electionem ex necessitate provenirent.
Some men, in their desire to show that the will is necessarily moved by the desirable in choosing, argued in such a way as to destroy the other root of contingency the Philosopher posits here, based on our deliberation. Since the good is the object of the will, they argue, it seems that cannot be diverted so as not to seek that which seems good to it—as, likewise, it is not possible to divert reason so that it does not assent to that which seems true to it. So it seems that choice, which follows upon deliberation, always takes place of necessity; thus all things of which we are the principle through deliberation and choice will take place of necessity.
Peri.L14
199. Sed dicendum est quod similis differentia est attendenda circa bonum sicut circa verum.
In regard to this point, there is a similar diversity with respect to the good and with respect to the true that must be noted.
Peri.L14
Est autem quoddam verum quod est per se notum, sicut prima principia indemonstrabilia quibus ex necessitate intellectus assentit.
There are some truths that are known in themselves, such as the first indemonstrable principles. The intellect assents to these of necessity.
Peri.L14
Sunt autem quaedam vera non per se nota, sed per alia, et horum duplex est conditio:
There are others, however, which are not known in itself, but through other truths. The condition of these is twofold.
Peri.L14
quaedam enim ex necessitate consequuntur ex principiis, ita scilicet quod non possunt esse falsa, principiis existentibus veris, sicut sunt omnes conclusiones demonstrationum; et huiusmodi veris ex necessitate assentit intellectus, postquam perceperit ordinem eorum ad principia, non autem prius;
Some follow necessarily from the principles, that is, so that they cannot be false when the principles are true. This is the case with all the conclusions of demonstrations, and the intellect assents necessarily to truths of this kind after it has perceived their order to the principles, but not before.
Peri.L14
quaedam autem sunt vera quae non ex necessitate sequuntur ex principiis, quia scilicet possunt esse falsa, principiis existentibus veris, sicut sunt opinabilia, quibus non ex necessitate assentit intellectus, quamvis ex aliquo motivo inclinetur magis in unam partem quam in aliam.
There are others that do not follow necessarily from the principles, and these can be false even though the principles are true. This is the case with things about which there can be opinion. To these the intellect does not assent necessarily, although it may be inclined by some motive more to one side than another.
Peri.L14
Ita etiam est quoddam bonum quod est propter se appetibile, sicut felicitas, quae habet rationem ultimi finis, et huiusmodi bono ex necessitate inhaeret voluntas: naturali enim quadam necessitate omnes appetunt esse felices.
Similarly, there is a good that is desirable for its own sake, namely, happiness, which has the nature of an ultimate end. The will necessarily adheres to a good of this kind, for all men seek to be happy by a certain kind of natural necessity.
Peri.L14
Quaedam vero sunt bona quae sunt appetibilia propter finem, quae comparantur ad finem sicut conclusiones ad principium, ut patet per Philosophum in II Physicorum.
There are other good things that are desirable for the sake of the end. These are related to the end as conclusions are to principles, as is clear from the Philosopher in Physics 2.7, 198a35.
Peri.L14
Si igitur essent aliqua bona quibus non existentibus non posset aliquis esse felix, haec etiam ex necessitate essent appetibilia, et maxime apud eum qui talem ordinem perciperet; et forte talia sunt esse, vivere et intelligere, et si qua alia sunt similia. Sed particularia bona, in quibus humani actus consistunt, non sunt talia, nec sub ea ratione apprehenduntur ut sine quibus felicitas esse non possit, puta comedere hunc cibum vel illum, aut abstinere ab eo, habent tamen in se unde moveant appetitum, secundum aliquod bonum consideratum in eis; et ideo voluntas non ex necessitate inducitur ad haec eligenda. Et propter hoc Philosophus signanter radicem contingentiae in his quae fiunt a nobis assignavit ex parte consilii, quod est eorum quae sunt ad finem et tamen non sunt determinata; in his enim in quibus media sunt determinata, non est opus consilio, ut dicitur in III Ethicorum.
If, then, there were some good things without the existence of which one could not be happy, these would be desirable of necessity, and especially by the person who perceives such an order. Perhaps being, living, and thinking (and other similar things, if there are any) are of this kind. However, particular good things with which human acts are concerned are not of this kind, nor are they apprehended as being such that without them happiness is impossible—for instance, to eat or abstain from this food or that. Nevertheless, such things do move the appetite according to some good considered in them. The will, therefore, is not induced to choose these of necessity. On this account, the Philosopher expressly designates the root of the contingency of things effected by us on the part of deliberation, which is concerned with those things that are for the end and yet are not determined. There is no need for deliberation in things in which the means are determined, as is said in Ethics 3.3, 1112a30–1113a14.
Peri.L14
Et haec quidem dicta sunt ad salvandum radices contingentiae quas hic Aristoteles ponit, quamvis videantur logici negotii modum excedere.
These things have been stated to save the roots of contingency that Aristotle posits here, although they may seem to exceed the mode of logical matter.
Peri.L14
L. 15 (Α.9, 19a23–19a39)It is concluded that propositions are true as they correspond to the way in which things are in reality
Ex modo quo veritas se habet circa res concluditur qualiter veritas se habeat circa propositiones
It is concluded that propositions are true as they correspond to the way in which things are in reality
Peri.L15
19a23. Igitur esse quod est quando est, et non esse quod non est quando non est, necesse est. Sed non omne quod est necesse est esse, nec quod non est necesse est non esse: non enim idem est omne quod est necessario esse quando est, et simpliciter esse ex necessitate. Similiter autem et in eo quod non est.
19a23. Now, that which is necessarily is when it is, and that which is not necessarily is not when it is not. But it is not necessary for everything that is, to be, nor is it necessary for that which is not, not to be. For these are not the same: that everything be necessarily when it is, and to be simply from necessity. And the case is similar with respect to that which is not.
Peri.L15
19a27. Et in contradictione eadem ratio est; esse quidem vel non esse omne necesse est et futurum esse vel non; non tamen dividentem dicere alterum necessario. Dico autem, necesse est quidem futurum esse bellum navale cras vel non esse futurum, sed non futurum esse cras bellum navale necesse est vel non futurum esse, futurum autem esse vel non esse necesse est.
19a27. And this is also the case with respect to contradiction. It is necessary that everything be or not be, and that it will be or will not be; however, taking them separately, it is not possible to say one of the two is necessary. For example, it is necessary that there will or will not be a naval battle tomorrow; however, it is not necessary that a naval battle take place tomorrow, nor is it necessary that it not take place. Yet it is necessary that it either take place or not take place.
Peri.L15
19a32. Quare, quoniam orationes verae sunt quemadmodum et res, manifestum est quoniam quaecumque sic se habent ut utrumlibet sint et contraria ipsorum contingere quaeant, necesse est similiter se habere et contradictionem.
19a32. And so, since speech is true as it corresponds to things, it is clear that when things are such that they are indeterminate to either of two, and opposites are possible, the corresponding contradiction must be similar.
Peri.L15
Quod contingit in his quae non semper sunt et non semper non sunt.
This is the case with those things that do not always exist or always not exist.
Peri.L15
Horum enim necesse est quidem alteram partem contradictionis veram esse vel falsam, non tamen hoc vel illud, sed utrumlibet, et magis quidem alteram veram, non tamen iam veram vel falsam.
Of these, it is necessary that one part of the contradiction be true or false—not, however, this or that part, but either of the two indeterminately. One may be more likely to be true, but it is not yet actually true or false.
Peri.L15
19a39. Quare manifestum est quoniam non est necesse omnes affirmationes et negationes oppositarum hanc quidem veram, illam autem falsam esse; neque enim quemadmodum in his quae sunt sic se habent etiam in his quae non sunt, possibilibus tamen esse aut non esse, sed quemadmodum dictum est.
19a39. Therefore, it is clear that it is not necessary that of every affirmation and negation of opposites, one is true and one false. For the case is not the same in regard to those things that are and those that are not but could be or not be. It is as we have just stated.
Peri.L15
200. Igitur esse quod est et cetera. Postquam Philosophus ostendit esse impossibilia ea quae ex praedictis rationibus sequebantur, hic, remotis impossibilibus, concludit veritatem.
Now, that which is. Now that the Philosopher has shown the impossibilities that follow from the foresaid arguments, he concludes what the truth is on this point.
Peri.L15
Et circa hoc duo facit: quia enim, arguendo ad impossibile, processerat ab enuntiationibus ad res et iam removerat inconvenientia quae circa res sequebantur,
In arguing to the impossibility of the position, he proceeded from enunciations to things, and has already rejected the unlikely consequences in respect to things.
Peri.L15
ordine converso, primo ostendit qualiter se habeat veritas circa res;
Now, in the converse order, he first shows the way in which there is truth about things;
Peri.L15
secundo qualiter se habeat veritas circa enuntiationes; ibi: Quare quoniam orationes verae sunt et cetera.
second, the way in which there is truth in enunciations, at: and so, since speech is true as it corresponds to things (19a32; [203]).
Peri.L15
Circa primum duo facit:
About the first he does two things:
Peri.L15
primo ostendit qualiter se habeat veritas et necessitas circa res absolute consideratas;
first, he shows the way in which there is truth and necessity about things absolutely considered;
Peri.L15
secundo qualiter se habeat circa eas per comparationem ad sua opposita, ibi: Et in contradictione eadem ratio est et cetera.
second, the way in which there is truth and necessity about things through a comparing of their opposites, at: and this is also the case with respect to contradiction (19a27; [202]).
Peri.L15
201. Dicit ergo primo, quasi ex praemissis concludens, quod, si praedicta sunt inconvenientia, ut scilicet omnia ex necessitate eveniant, oportet dicere ita se habere circa res, scilicet quod omne quod est, necesse est esse quando est, et omne quod non est necesse est non esse quando non est.
First, he says, as though concluding from premises, that if the foresaid things are unlikely (namely, that all things take place of necessity), then the case with respect to things must be this: everything that is must be when it is, and everything that is not necessarily not be when it is not.
Peri.L15
Et haec necessitas fundatur super hoc principium: ‘impossibile est simul esse et non esse’; si enim aliquid est, impossibile est illud simul non esse, ergo necesse est tunc illud esse; nam ‘impossibile non esse’ idem significat ei quod est ‘necesse esse’, ut in II huius dicetur; et similiter, si aliquid non est, impossibile est illud simul esse, ergo necesse est non esse, quia haec etiam idem significant; ideo manifeste verum est quod omne quod est necesse est esse quando est, et omne quod non est necesse est non esse pro illo tempore quando non est.
This necessity is founded on the principle that it is impossible at once to be and not be. For if something is, it is impossible that it at the same time not be. Therefore, it is necessary that it be at that time. For “impossible not to be” signifies the same thing as “necessary to be,” as Aristotle says in the second book. Similarly, if something is not, it is impossible that it at the same time be. Therefore, it is necessary that it not be, for they also signify the same thing. Clearly it is true, then, that everything that is must be when it is, and everything that is not must not be when it is not.
Peri.L15
Et est haec necessitas non absoluta, sed ex suppositione; unde non potest simpliciter <et> absolute dici quod omne quod est, necesse est esse, et omne quod non est, necesse est non esse, quia non idem significant quod omne ens quando est sit ex necessitate, et quod omne ens simpliciter sit ex necessitate: nam primum significat necessitatem ex suppositione, secundum autem necessitatem absolutam. Et quod dictum est de esse, intelligendum est similiter de non esse, quia aliud est simpliciter ex necessitate non esse, et aliud est ex necessitate non esse quando non est.
This is not absolute necessity, but necessity by supposition. Consequently, it cannot be said absolutely and simply that everything that is must be, and that everything that is not must not be. For to say that every being necessarily is when it is, does not signify the same thing as saying that every being necessarily is, simply. The first signifies necessity by supposition; the second, absolute necessity. What has been said about “to be” must be understood to apply also to “not to be,” for “necessarily not to be simply” and “necessarily not to be when it is not” are also different.
Peri.L15
Et per hoc videtur Aristoteles excludere id quod supra dictum est quod, si in his quae sunt alterum determinate est verum, quod etiam ante quam fieret alterum determinate esset futurum.
By this Aristotle seems to exclude what was said above, namely, that if in those things that are, one of the two is determinately true, then even before it takes place one of the two would determinately be going to happen.
Peri.L15
202. Deinde cum dicit: Et in contradictione et cetera, ostendit quomodo se habeat veritas circa res per comparationem ad sua opposita.
He shows how truth is had about things through comparison with their opposites, at: this is also the case with respect to contradiction (19a27).
Peri.L15
Et dicit quod eadem ratio est in contradictione, quae est in suppositione: sicut enim id quod non est absolute necessarium fit necessarium ex suppositione eiusdem, quia necesse est esse quando est, ita etiam quod non est in se necessarium absolute, fit necessarium per disiunctionem oppositi, quia necesse est de unoquoque quod sit vel quod non sit <et quod futurum sit vel non sit>, et hoc sub disiunctione.
The reasoning is the same, he says, in respect to contradiction and in respect to supposition. For just as that which is not absolutely necessary becomes necessary by supposition of the same (for it must be when it is), so also what in itself is not absolutely necessary becomes necessary through the disjunction of the opposite, for it is necessary that each thing be or not be, and that it will or will not be in the future (and this is under disjunction).
Peri.L15
Et haec necessitas fundatur super hoc principium quod ‘Impossibile est contradictoria simul esse <vera vel> falsa’; unde impossibile est neque esse neque non esse, ergo necesse est vel esse vel non esse; non tamen, si divisim alterum accipiatur, necesse est illud esse absolute.
This necessity is founded upon the principle that it is impossible for contradictories to be at once true and false. Accordingly, it is impossible that a thing neither be nor not be; therefore, it is necessary that it either be or not be. However if one of these is taken separately, it is not necessary that this one be absolutely.
Peri.L15
Et hoc manifestat per exemplum, quia necesse est navale bellum esse futurum cras vel non esse, sed non est necesse navale bellum futurum esse cras; similiter etiam non est necesse non esse futurum, quia hoc pertinet ad necessitatem absolutam, sed necesse est quod vel sit futurum vel non sit futurum, hoc enim pertinet ad necessitatem quae est sub disiunctione.
This he manifests by example: it is necessary that there will be or will not be a naval battle tomorrow, but it is not necessary that a naval battle will take place tomorrow, nor is it necessary that it will not take place, for this pertains to absolute necessity. It is necessary, however, that it will take place or will not take place tomorrow. This pertains to the necessity which is under disjunction.
Peri.L15
203. Deinde cum dicit: Quare quoniam orationes et cetera, ex eo quod se habet circa res, ostendit qualiter se habeat circa orationes.
Then, when he says: and so, since speech is true as it corresponds to things (19a32), he shows how truth in speech corresponds to the way things are.
Peri.L15
Et primo ostendit quomodo uniformiter se habet in veritate orationum sicut circa esse rerum;
First, he shows in what way truth of speech conforms to the being and non-being of things;
Peri.L15
secundo finaliter concludit veritatem totius dubitationis, ibi: Quare manifestum et cetera.
second, he finally arrives at the truth of the whole question, at: therefore, it is clear (19a39; [204]).
Peri.L15
Dicit ergo primo quod, quia hoc modo se habent orationes enuntiativae ad veritatem sicut et res ad esse vel non esse (quia ex eo quod res est vel non est, oratio est vera vel falsa), consequens est quod in omnibus rebus quae ita se habent ut sint ad utrumlibet, et quaecumque ita se habent quod contraria eorum qualitercumque contingere possunt, sive aequaliter sive alterum ut in pluribus, ex necessitate sequitur quod etiam similiter se habeat circa contradictionem enuntiationum.
He says, then, that enunciative speech is related to truth in the way the thing is to being or non-being (for from the fact that a thing is or is not, speech is true or false). It follows, therefore, that when things are such as to be indeterminate to either of two, and when they are such that their contraries could happen in whichever way (whether equally or one, for the most part), the contradiction of enunciations must also be such.
Peri.L15
Et exponit consequenter quae sint illae res quarum contraria contingere queunt. Et dicit huiusmodi esse quae neque semper sunt, sicut necessaria, neque semper non sunt, sicut impossibilia, sed quandoque sunt et quandoque non sunt.
He explains next what the things are in which contradictories can happen. They are those that neither always are (that is, the necessary), nor always are not (that is, the impossible), but sometimes are and sometimes are not.
Peri.L15
Et ulterius manifestat quomodo similiter se habeat in contradictoriis enuntiationibus. Et dicit quod harum enuntiationum quae sunt de contingentibus necesse est quod sub disiunctione altera pars contradictionis sit vera vel falsa, non tamen haec vel illa determinate, sed se habet ad utrumlibet; et, si contingat quod altera pars contradictionis magis sit vera, sicut accidit in contingentibus quae sunt ut in pluribus, non tamen ex hoc necesse est quod ex necessitate altera earum determinate sit vera vel falsa.
He shows further how this is maintained in contradictory enunciations. In those enunciations that are about contingent things, one part of the contradiction must be true or false under disjunction; but it is related to either, not to this or that determinately. If it should turn out that one part of the contradiction is more true, as happens in contingencies that are for the most part, it is nevertheless not necessary on this account that one of them is determinately true or false.
Peri.L15
204. Deinde cum dicit: Quare manifestum est et cetera, concludit principale intentum.
Then he says: therefore, it is clear (19a39). This is the conclusion he principally intended.
Peri.L15
Et dicit manifestum esse ex praedictis quod non est necesse in omni genere affirmationum et negationum oppositarum alteram determinate esse veram et alteram falsam, quia non eodem modo se habet veritas et falsitas in his quae sunt iam de praesenti et in his quae non sunt, sed possunt esse vel non esse; sed hoc modo se habet in utriusque sicut dictum est, quia scilicet in his quae sunt necesse est determinate alterum esse verum et alterum esse falsum, quod non contingit in futuris, quae possunt esse et non esse.
It is evident from what has been said that it is not necessary in every genus of affirmation and negation of opposites that one is determinately true and the other false, for truth and falsity is not had in the same way in regard to things that are already in the present and those that are not but which could be or not be. The position in regard to each has been explained. In those that are, it is necessary that one of them be determinately true and the other false; in things that are future, which could be or not be, the case is not the same.
Peri.L15
Et in hoc terminatur primus liber.
The first book ends with this.
Peri.L15
Book 2
L. 1 (A.10, 19b5–19b19)The distinction and order of simple enunciations, in which the finite or the infinite name is posited only on the part of the subjectDe distinctione et ordine simplicium enunciationum, in quibus nomen finitum vel infinitum ponitur tantum ex parte subiec
19b5. Quoniam autem est de aliquo affirmatio significans aliquid, hoc autem est vel nomen vel innominatum. Unum autem oportet esse et de uno hoc quod est in affirmatione.
19b5. An affirmation signifies something about something, and the subject is either the name or that which has no name, and one thing must be signified about one thing in an affirmation.
Peri.L1
19b7. Nomen autem dictum est et innominatum prius: ‘non homo’ enim nomen quidem non dico, sed infinitum nomen (unum enim quodam modo significat infinitum), quemadmodum et ‘non currit’ non verbum, sed infinitum verbum.
19b7. We have already stated what a name is and that which has no name: I do not call “non-man” a name, but an infinite name—for an infinite name also signifies one thing in a certain way—nor “non-matures” a verb, but an infinite verb.
Peri.L1
19b10. Erit autem omnis affirmatio vel ex nomine et verbo, vel ex infinito nomine et verbo.
19b10. Every affirmation will be made up of a name and a verb or an infinite name and a verb.
Peri.L1
19b12. Praeter verbum autem nulla est affirmatio vel negatio. ‘Est’ enim vel ‘erit’ vel ‘fuit’, vel quaecumque alia huiusmodi, verba sunt ex his quae sunt posita: consignificant enim tempus.
19b12. There can be no affirmation or negation without a verb; for according to what has been established, “is,” or “will be,” or “was,” or “becomes,” or any others such as these are verbs, since they signify with time.
Peri.L1
19b14. Quare prima erit affirmatio et negatio: ‘Est homo—Non est homo’; deinde: ‘Est non homo—Non est non homo’; rursus: ‘Est omnis homo—Non est omnis homo’, ‘Est omnis non homo—Non est omnis non homo’. Et in extrinsecis temporibus eadem ratio est.
19b14. Therefore, the primary affirmation and negation is “man is—man is not”; then, “non-man is—non-man is not”; and then “every man is—not every man is”; “every non-man is—not every non-man is.” There are similar affirmations and negations with regard to times outside of the present.
Peri.L1
205. Quoniam autem est de aliquo affirmatio et cetera. Postquam Philosophus in I libro determinavit de enuntiatione simpliciter considerata, hic determinat de enunciatione secundum quod diversificatur per aliquid sibi additum.
Since an affirmation signifies something about something. In the first book, the Philosopher has dealt with the enunciation considered simply. Now, he is going to treat of the enunciation as it is diversified by the addition of something to it.
Peri.L1
Possunt autem tria in enuntiatione considerari:
There are three things that can be considered in the enunciation:
Peri.L1
primo ipsae dictiones quae praedicantur vel subiiciuntur in enuntiatione, quas supra distinxit per nomina et verba;
first, the words that are predicated or subjected, which he has already distinguished into names and verbs;
Peri.L1
secundo ipsa compositio secundum quam est verum vel falsum in enuntiatione affirmativa vel negativa;
second, the composition, according to which there is truth or falsity in the affirmative or negative enunciation;
Peri.L1
tertio ipsa oppositio unius enuntiationis ad aliam.
third, the opposition of one enunciation to another.
Peri.L1
Dividitur ergo haec pars in tres partes:
This book is divided into three parts:
Peri.L1
in prima ostendit quid accidat enuntiationi ex hoc quod aliquid additur ad dictiones in subiecto vel praedicato positas;
In the first, he shows what happens to the enunciation when something is added to the words posited as the subject or predicate;
Peri.L1
secundo quid accidat enuntiationi ex hoc quod aliquid additur ad determinandum veritatem vel falsitatem compositionis, ibi: His vero determinatis et cetera;
in the second, he shows what happens when something is added to determine the truth or falsity of the composition, at: having determined these things (21a34; [290]);
Peri.L1
tertio solvit quamdam dubitationem circa oppositiones enuntiationum provenientem ex eo quod additur aliquid simplici enuntiationi, ibi: Utrum autem contraria est affirmatio et cetera.
in the third, he solves a question that arises about the oppositions of enunciations in which something is added to the simple enunciation, at: there is a question as to whether the contrary of an affirmation (23a27; [349]).
Peri.L1
Est autem considerandum quod additio facta ad praedicatum vel subiectum quandoque tollit unitatem enuntiationis, quandoque vero non tollit, sicut additio negationis infinitantis dictionem.
It should be noted that an addition made to the predicate or the subject sometimes destroys the unity of the enunciation, and sometimes does not, as when the addition is a negative making a word infinite.
Peri.L1
Circa primum ergo duo facit:
About the first he does two things:
Peri.L1
primo ostendit quid accidat enuntiationibus ex additione negationis infinitantis dictionem;
first, he shows what happens to the enunciation when the added negation makes a word infinite;
Peri.L1
secundo ostendit quid accidat circa enuntiationem ex additione tollente unitatem, ibi: At vero unum de pluribus et cetera.
second, he shows what happens when an addition destroys the unity of the enunciation, at: neither the affirmation nor the negation (20b12; [254]).
Peri.L1
Circa primum duo facit:
About the first he does two things:
Peri.L1
primo determinat de enuntiationibus simplicissimis, in quibus nomen finitum vel infinitum ponitur tantum ex parte subiecti;
first, he investigates the simplest of enunciations, in which a finite or infinite name is posited only on the part of the subject;
Peri.L1
secundo determinat de enuntiationibus in quibus nomen finitum vel infinitum ponitur non solum ex parte subiecti, sed etiam ex parte praedicati, ibi: Quando autem ‘est’ tertium adiacens et cetera.
second, he considers the enunciation in which a finite or infinite name is posited not only on the part of the subject, but also on the part of the predicate, at: but when “is” is predicated as a third element (19b19; [211]).
Peri.L1
Circa primum duo facit:
About the first he does two things:
Peri.L1
primo proponit rationes quasdam distinguendi tales enuntiationes;
first, he proposes certain grounds for distinguishing such enunciations;
Peri.L1
secundo ponit earum distinctionem et ordinem, <ibi>: Quare prima est affirmatio et cetera.
second, he gives their distinction and order, at: therefore, the primary affirmation (19b14; [210]).
Peri.L1
Circa primum duo facit:
About the first he does two things:
Peri.L1
primo ponit rationes distinguendi enuntiationes ex parte nominum;
first, he gives the grounds for distinguishing enunciations on the part of the name;
Peri.L1
secundo ostendit quod non potest esse eadem ratio distinguendi ex parte verborum, ibi: Praeter verbum, et cetera.
second, he shows that there are not the same grounds for a distinction on the part of the verb, at: there can be no affirmation or negation without a verb (19b12; [209]).
Peri.L1
Circa primum tria facit:
About the first he does three things:
Peri.L1
primo proponit rationes distinguendi enuntiationes;
first, he proposes the grounds for distinguishing these enunciations;
Peri.L1
secundo exponit quod dixerat, ibi: Nomen autem dictum est et cetera;
second, he explains this, at: we have already stated what a name is (19b7; [207]);
Peri.L1
tertio concludit intentum, ibi: Erit autem omnis affirmatio et cetera.
third, he arrives at the conclusion he intended, at: every affirmation will be made up of a name and a verb (19b10; [208]).
Peri.L1
206. Resumit ergo primo id quod supra dictum est de definitione affirmationis, quod scilicet affirmatio est enuntiatio significans aliquid de aliquo; et, quia verbum proprie est nota eorum quae de alio dicuntur, consequens est ut id de quo aliquid dicitur pertineat ad nomen; nomen autem est vel finitum vel infinitum; et ideo, quasi concludens, subdit quod, quia affirmatio significat aliquid de aliquo, consequens est ut hoc, de quo significatur, scilicet subiectum affirmationis, sit vel nomen, scilicet finitum (quod proprie dicitur nomen, ut <in> I dictum est), vel innominatum, id est nomen infinitum, quod dicitur innominatum, quia ipsum non nominat aliquid ab aliqua forma determinata, sed solum removet determinationem formae. Et, ne aliquis diceret quod id quod in affirmatione subiicitur est simul nomen et innominatum, ad hoc excludendum subdit quod id quod est, scilicet praedicatum, in affirmatione, scilicet una, de qua nunc loquimur, oportet esse unum et de uno subiecto; et sic oportet quod subiectum talis affirmationis vel sit nomen vel nomen infinitum.
First of all, he goes back to what was said above in defining affirmation, namely, that an affirmation is an enunciation signifying something about something. Since it is peculiar to the verb to be a sign of what is predicated of another, it follows that that about which something is said pertains to the name. But the name is either finite or infinite; therefore, as if drawing a conclusion, he says that since affirmation signifies something about something, it follows that that about which something is signified—that is, the subject of an affirmation—is either a finite name (which is properly called a name), or unnamed, that is, an infinite name. It is called “unnamed” because it does not name something with a determinate form but removes the determination of form. And lest anyone think that what is subjected in an affirmation is at once a name and unnamed, he adds: and one thing must be signified about one thing in an affirmation, that is, in the enunciation, of which we are speaking now. Hence the subject of such an affirmation must be either the name or the infinite name.
Peri.L1
207. Deinde cum dicit: Nomen autem et cetera, exponit quod dixerat.
When he says: we have already stated what a name is (19b7), he relates what he has previously said.
Peri.L1
Et dicit quod supra dictum est quid sit nomen et quid sit innominatum, id est infinitum nomen, quia ‘non homo’ non est nomen, sed est infinitum nomen, sicut et ‘non currit’ non est verbum, sed infinitum verbum. Interponit autem quiddam quod valet ad dubitationis remotionem, videlicet quod nomen infinitum quodam modo significat unum: non enim significat simpliciter unum, sicut nomen finitum quod significat unam formam generis vel speciei aut etiam individui, sed in quantum significat negationem formae alicuius, in qua negatione multa conveniunt, sicut in quodam uno secundum rationem: unum enim eodem modo dicitur aliquid sicut et ens, unde sicut ipsum non ens dicitur ens, non quidem simpliciter sed secundum quid, id est secundum rationem, ut patet in IV Metaphysicae, ita etiam negatio est unum secundum quid, id est secundum rationem. Introducit autem hoc ne aliquis dicat quod affirmatio in qua subiicitur nomen infinitum non significat unum de uno, quasi nomen infinitum non significet unum.
We have already stated, he says, what a name is and what that which is unnamed is, that is, the infinite name. “Non-man” is not a name but an infinite name, and “non-runs” is not a verb but an infinite verb. Then he interposes a point that is useful for the preclusion of a difficulty, namely, that an infinite name in a certain way does signify one thing. It does not signify one thing simply as the finite name does, which signifies one form of a genus or species, or even of an individual; rather, it signifies one thing insofar as it signifies the negation of a form, in which negation many things are united, as in something one according to reason. For something is said to be one in the same way it is said to be a being. Hence, just as non-being is said to be being not simply, but according to something—that is, according to reason, as is evident in Metaphysics 4.21, 1003b6—so also a negation is one according to something, namely, reason. Aristotle introduces this point so that no one will say that an affirmation in which an infinite name is the subject does not signify one thing about one subject, on the grounds that an infinite name does not signify something one.
Peri.L1
208. Deinde cum dicit: Erit autem omnis affirmatio et cetera, concludit propositum, scilicet quod duplex est modus affirmationum.
When he says: every affirmation will be made up of a name and a verb (19b10), he concludes that the mode of affirmation is twofold:
Peri.L1
Quaedam enim est affirmatio quae constat ex nomine et verbo,
one affirmation consists of a name and a verb,
Peri.L1
quaedam autem est quae constat ex infinito nomine et verbo.
the other of an infinite name and a verb.
Peri.L1
Et hoc sequitur ex hoc quod supra dictum est, quod hoc de quo affirmatio aliquid significat vel est nomen vel innominatum. Et eadem differentia potest accipi ex parte negationis, quia de quocunque contingit affirmare, contingit et negare, ut <in> I habitum est.
This follows from what has been said, namely, that that about which an affirmation signifies something is either a name or unnamed. The same difference can be taken on the part of negation, for of whatever something can be affirmed, it can be denied, as was said in the first book.
Peri.L1
209. Deinde cum dicit: Praeter verbum autem et cetera, ostendit quod differentia enuntiationum non potest sumi ex parte verbi.
When he says: there can be no affirmation or negation without a verb (19b12), he intends to show that enunciations cannot be differentiated on the part of the verb.
Peri.L1
Dictum est enim supra quod praeter verbum nulla est affirmatio vel negatio.
He made the point earlier that there is no affirmation or negation without a verb.
Peri.L1
Potest autem praeter nomen esse aliqua affirmatio vel negatio, videlicet si ponatur loco nominis infinitum nomen; loco autem verbi in enuntiatione non potest poni infinitum verbum, duplici ratione.
However, there can be an affirmation or negation without a name: namely, when an infinite name is posited in place of a name. An infinite verb, on the other hand, cannot be posited in an enunciation in place of a verb, and this for two reasons.
Peri.L1
Primo quidem quia infinitum verbum constituitur per additionem negativae particulae; quae quidem addita verbo per se dicto, id est extra enuntiationem posito, removet ipsum absolute, sicut et addita nomini removet formam nominis absolute, et ideo extra enuntiationem potest accipi verbum <infinitum> per modum unius dictionis, sicut et nomen infinitum; sed, quando negatio additur verbo in enuntiatione posito, negatio illa removet verbum ad aliquo, et sic facit enuntiationem negativam, quod non accidit ex parte nominis; non enim enuntiatio efficitur negativa nisi propter hoc quod negatur compositio quae importatur in verbo; et ideo verbum infinitum in enuntiatione positum fit verbum negativum.
First, the infinite verb is constituted by the addition of an infinite particle which, when added to a verb said by itself (that is, posited outside of the enunciation), removes it absolutely, just as it removes the form of the name absolutely when added to it. Therefore, outside of the enunciation, the infinite verb can be taken in the mode of one word, as can the infinite name. But when a negation is added to the verb in an enunciation, it removes the verb from something and thus makes the enunciation negative, which is not the case with respect to the name. For an enunciation is made negative by denying the composition which the verb introduces; hence, an infinite verb posited in the enunciation becomes a negative verb.
Peri.L1
Secundo quia in nullo variatur veritas enuntiationis sive utamur negativa particula ut infinitante verbum vel ut faciente negativam enuntiationem, et ideo accipitur semper secundum simpliciorem intellectum, prout est magis in promptu; et inde est quod non diversificavit affirmationem per hoc quod sit ex verbo vel infinito verbo, sicut diversificavit <per hoc> quod est ex nomine vel ex infinito nomine.
Second, whichever way we use the negative particle, whether as making the verb infinite or as making a negative enunciation, the truth of the enunciation is not changed. The negative particle, therefore, is always taken in the more absolute sense, as being clearer. This, then, is why Aristotle does not diversify the affirmation as made up of a verb or infinite verb, but as made up of a name or an infinite name.
Peri.L1
Est autem considerandum quod in nominibus et verbis, praeter differentiam finiti et infiniti, est differentia recti et obliqui; <obliqui vero> nominis, etiam verbo addito, non constituunt enuntiationem significantem verum vel falsum, ut in I habitum est, quia in obliquo nominis non includitur ipse rectus; sed in casibus verbi includitur ipsum verbum praesentis temporis: praeteritum enim et futurum, quae consignificant casus verbi, dicuntur per respectum ad praesens, unde si dicatur: ‘Hoc erit’, idem est ac si diceretur: ‘Hoc est futurum’; ‘Hoc fuit’, ‘Hoc est praeteritum’. Et propter hoc ex casu verbi et nomine fit enuntiatio.
It should also be noted that besides the difference of finite and infinite, there is the difference of nominative and oblique cases. The cases of names even with a verb added do not constitute an enunciation signifying truth or falsity, as was said in the first book, for the nominative is not included in an oblique name. The verb of present time, however, is included in the cases of the verb, for the past and future, which the cases of the verb signify, are said with respect to the present. Hence, if we say, “This will be,” it is the same as if we were to say, “This is future,” and “This has been” is the same as “This is past.” Thus, A name and a case of the verb do constitute an enunciation.
Peri.L1
Et ideo subiungit quod sive dicatur ‘est’, sive ‘erit’, sive ‘fuit’, vel quaecumque alia huiusmodi, verba sunt de numero praedictorum verborum sine quibus non potest fieri enuntiatio, quia omnia consignificant tempus, et alia tempora dicuntur per respectum ad praesens.
Therefore, Aristotle adds that “is," or "will be," or "was", or any other verb of this kind are of the number of the foresaid verbs without which an enunciation cannot be made, since they all signify with time, and past and future time are said with respect to the present.
Peri.L1
210. Deinde cum dicit: Quare prima est affirmatio et cetera, concludit ex praemissis distinctionem enuntiationum in quibus nomen finitum vel infinitum ponitur solum ex parte subiecti.
When he says: therefore, the primary affirmation and negation is (19b14), he infers from the premises the distinction of enunciations in which the finite and infinite name is posited only on the part of the subject.
Peri.L1
In quibus triplex differentia intelligi potest,
Among these there is a threefold difference to be noted:
Peri.L1
una quidem secundum affirmationem et negationem,
the first, according to affirmation and negation;
Peri.L1
alia secundum subiectum finitum et infinitum,
the second, according to finite and infinite subject;
Peri.L1
tertia secundum subiectum universaliter vel non universaliter sumptum.
the third, according as the subject is posited universally or not universally.
Peri.L1
Nomen autem finitum est naturaliter prius infinito sicut affirmatio prior est negatione, unde primam affirmationem ponit: ‘Homo est’, primam autem negationem: ‘Homo non est’; deinde ponit secundam affirmationem: ‘Non homo est’, secundam autem negationem: ‘Non homo non est’; ulterius autem ponit illas enuntiationes in quibus subiectum universaliter ponitur, quae sunt etiam quatuor, sicut et illae in quibus est subiectum non universaliter positum.
Now, the finite name is prior in notion to the infinite name, just as affirmation is prior to negation. Accordingly, he posits “man is” as the first affirmation and “man is not” as the first negation. Then he posits the second affirmation, “non-man is,” and the second negation, “non-man is not.” Finally, he posits the enunciations in which the subject is universally posited. These are four, as are those in which the subject is not universally posited.
Peri.L1
Praetermisit autem ponere exemplum de enuntiationibus in quibus subiicitur singulare, ut: ‘Socrates est—Socrates non est’, quia singularibus nominibus non additur aliquod signum; unde in huiusmodi enuntiationibus non potest omnis differentia inveniri.—Similiter etiam praetermittit exemplificare de enuntiationibus quarum subiecta particulariter ponuntur, quia tale subiectum quodam modo eamdem vim habet cum subiecto universali non universaliter sumpto.
The reason he does not give examples of the enunciation with a singular subject, such as “Socrates is” and “Socrates is not,” is that no sign is added to singular names, and hence not every difference can be found in them. Nor does he give examples of the enunciation in which the subject is taken particularly, for such a subject in a certain way has the same force as a universal subject not universally taken.
Peri.L1
Non ponit autem aliquam differentiam ex parte verbi, quae posset sumi secundum casus verbi, quia, sicut ipse dicit, in extrinsecis temporibus, id est in praeterito et futuro quae circumstant praesens, est eadem ratio sicut in praesenti, ut iam dictum est.
He does not posit any difference on the part of the verb according to its cases because, as he himself says, affirmations and negations in regard to extrinsic times—that is, past and future time which surround the present—are similar to these, as has already been said.
Peri.L1
L. 2 (Α.10, 19b19–19b26)The number and relationship of simple enunciations, in which the verb “is” is predicated as a third element and the subject is the finite name not universally takenDe numero et habitudine inter se simplicium enunciationum de tertio adiacente, in quibus praedicatur verbum ‘est’ et sub
19b19. Quando autem ‘est’ tertium adiacens praedicatur, dupliciter dicuntur oppositiones.
19b19. But when “is” is predicated as a third element in the enunciation, there are two oppositions.
Peri.L2
19b20. Dico autem ut: ‘Est iustus homo’, ‘est’ tertium dico adiacens nomen vel verbum in affirmatione.
19b20. I mean by this that in an enunciation such as “man is just,” the “is” is a third name or verb contained in the affirmation.
Peri.L2
19b22. Idcirco quatour iste erunt.
19b22. In this case, therefore, there will be four enunciations.
Peri.L2
19b23. Quarum duae quidem ad affirmationem et negationem sese habent secundum consequentiam ut privationes, duae vero minime.
19b23. Two of these will correspond in their sequence (in respect of affirmation and negation) with the privations, but two will not.
Peri.L2
19b24. Dico autem quoniam ‘est’ aut ‘iusto’ adiacebit aut ‘non iusto’; quare etiam negationes. Quatuor ergo sunt.
19b24. I mean that the “is” will be added either to “just” or to “non-just”; and so also in the case of the negative. Thus there will be four.
Peri.L2
Intellegimus vero quod dicitur ex his quae subscripta sunt: est iustus homo—huius negatio: non est iustus homo est non iustus homo—negatio: non est non iustus homo; 'est' enim hoc loco et 'non est' 'iusto' et 'non iusto' adiacet. Haec igitur, quemadmodum in Resolutoriis dictum est, sic sunt disposita.
19b27. The following diagram will make this clear: man is just—man is not just; man is not not-just—man is not-just. Here "is" and "is not" are added either to "just" or to "not-just." This, then, is the way these are arranged, as we have said in the Analytics.
Peri.L2
211. Quando autem ‘est’ tertium adiacens et cetera. Postquam Philosophus distinxit enuntiationes in quibus nomen finitum vel infinitum ponitur solum ex parte subiecti, hic accedit ad distinguendum illas enuntiationes in quibus nomen finitum vel infinitum ponitur ex parte subiecti et ex parte praedicati.
But when “is” is predicated as a third element. After distinguishing enunciations in which either a finite or an infinite name is posited only on the part of the subject, the Philosopher begins here to distinguish enunciations in which either a finite or an infinite name is posited as the subject and as the predicate.
Peri.L2
Et circa hoc duo facit:
About this he does two things:
Peri.L2
primo distinguit huiusmodi enuntiationes;
first, he distinguishes these enunciations;
Peri.L2
secundo manifestat quaedam quae circa eas dubia esse possent, ibi: Quoniam vero contraria est et cetera.
second, he manifests certain things that might be doubtful in relation to them, at: since the negation contrary (20a16; [242]).
Peri.L2
Circa primum duo facit:
About the first he does two things:
Peri.L2
primo agit de enuntiationibus in quibus nomen praedicatur cum hoc verbo ‘est’;
first, he deals with enunciations in which the name is predicated with the verb “is”;
Peri.L2
secundo de enunciationibus in quibus alia verba ponuntur, ibi: In his vero in quibus et cetera.
second, with those in which other verbs are used, at: in enunciations in which “is" (20a3; [237]).
Peri.L2
Distinguit autem huiusmodi enuntiationes, sicut et primas, secundum triplicem differentiam ex parte subiecti consideratam:
He distinguishes these enunciations as he did the primary enunciations, according to a triple difference on the part of the subject:
Peri.L2
primo namque agit de enuntiationibus in quibus subiicitur nomen finitum non universaliter sumptum;
first, he treats those in which the subject is a finite name not taken universally;
Peri.L2
secundo de illis in quibus subiicitur nomen finitum universaliter sumptum, ibi: Similiter autem se habet et cetera;
second, those in which the subject is a finite name taken universally, at: the same is the case when the affirmation (19b32; [226]);
Peri.L2
tertio de illis in quibus subiicitur nomen infinitum, ibi: Aliae autem ad ‘non homo’ et cetera.
third, those in which an infinite name is the subject, at: and there are two other pairs (19b36; [234]).
Peri.L2
Circa primum tria facit:
About the first he does three things:
Peri.L2
primo proponit diversitatem oppositionis talium enuntiationum;
first, he proposes a diversity of oppositions;
Peri.L2
secundo concludit earum numerum et ponit earum habitudinem, ibi: Idcirco quatuor et cetera;
second, he concludes as to their number and states their relationship, at: in this case, therefore, there will be four enunciations (19b22; [215]);
Peri.L2
tertio exemplificat quasi in figura, ibi: Intelligimus vero et cetera.
third, he exemplifies this with a table.
Peri.L2
Circa primum duo facit:
Concerning the first he does two things:
Peri.L2
primo proponit quod intendit;
first, he sets forth what he intends to do;
Peri.L2
secundo exponit quiddam quod dixerat, ibi: Dico autem et cetera.
second, he explains what he had said, at: I mean by this (19b20; [214]).
Peri.L2
212. Circa primum duo oportet intelligere.
In relation to the first point two things have to be understood.
Peri.L2
Primo quidem, quid est hoc quod <dicit quod> ‘est’ tertium adiacens praedicatur. Ad cuius evidentiam considerandum est quod hoc verbum ‘est’ quandoque in enuntiatione praedicatur secundum se, ut cum dicitur: ‘Socrates est’, per quod nihil aliud intendimus significare quam quod Socrates sit in rerum natura; quandoque vero non praedicatur per se, quasi principale praedicatum, sed quasi coniunctum principali praedicato ad connectendum ipsum subiecto, sicut cum dicitur: ‘Socrates est albus’: non enim est intentio loquentis ut asserat Socratem esse in rerum natura, sed ut attribuat ei albedinem mediante hoc verbo ‘est’; et ideo in talibus ‘est’ praedicatur ut adiacens principali praedicato, et dicitur esse tertium non quia sit tertium praedicatum, sed quia est tertia dictio posita in enuntiatione, quae simul cum nomine praedicato facit unum praedicatum, ut sic enuntiatio dividatur in duas partes, non in tres.
First, what he means by: “is” is predicated as a third element in the enunciation (19b19). To clarify this, we must note that the verb “is” itself is sometimes predicated in an enunciation, as in “Socrates is.” By this we intend to signify that Socrates really is. Sometimes, however, “is” is not predicated as the principal predicate, but is joined to the principal predicate to connect it to the subject, as in “Socrates is white.” Here the intention is not to assert that Socrates really is, but to attribute whiteness to him by means of the verb “is.” Hence, in such enunciations, “is” is predicated as added to the principal predicate. It is said to be third not because it is a third predicate, but because it is a third word posited in the enunciation, which together with the name predicated makes one predicate. The enunciation is thus divided into two parts and not three.
Peri.L2
213. Secundo considerandum est quid est quod dicit quod quando ‘est’, eo modo quo dictum est, tertium adiacens praedicatur, dupliciter dicuntur oppositiones. Circa quod considerandum est quod in praemissis enuntiationibus in quibus nomen ponebatur solum ex parte subiecti, secundum quodlibet subiectum erat una oppositio, puta, si subiectum erat nomen finitum non universaliter sumptum, erat sola una oppositio, scilicet: ‘Est homo—Non est homo’. Sed, quando ‘est’ tertium adiacens praedicatur, oportet esse duas oppositiones, eodem subiecto existente, secundum differentiam nominis praedicati, quod potest esse finitum vel infinitum, sicut haec est una oppositio: ‘Homo est iustus—Homo non est iustus’; alia vero oppositio est: ‘Homo est non iustus—Homo non est non iustus’; non enim negatio fit nisi per appositionem negativae particulae ad hoc verbum ‘est’, quod est nota praedicationis.
Second, we must consider what he means by when “is” is predicated as a third element in the enunciation (19b19), in the mode in which we have explained, there are two oppositions. In the enunciations already treated, in which the name is posited only on the part of the subject, there was one opposition in relation to any subject. For example, if the subject was a finite name not taken universally, there was only one opposition: “man is—man is not.” But when “is” is predicated in addition, there are two oppositions with regard to the same subject corresponding to the difference of the predicate name, which can be finite or infinite. There is the opposition of “man is just—man is not just,” and the opposition, “man is non-just—man is not non-just.” For the negation is effected by applying the negative particle to the verb “is,” which is a sign of a predication.
Peri.L2
214. Deinde cum dicit: Dico autem et cetera, exponit quod dixerat: ‘est’ tertium adiacens.
When he says: I mean by this (19b20), he explains what he said: when “is” is predicated as a third element in the enunciation.
Peri.L2
Et dicit quod, cum dicitur: ‘Homo est iustus’, hoc verbum ‘est’ adiacet, scilicet praedicato, tamquam tertium nomen vel verbum in affirmatione. Potest enim ipsum ‘est’ dici nomen, prout quaelibet dictio nomen dicitur, et sic est tertium nomen, id est tertia dictio. Sed, quia secundum communem usum loquendi dictio consignificans tempus magis dicitur verbum quam nomen, propter hoc addit: vel verbum, quasi dicat: ad hoc quod sit tertium, non refert utrum dicatur nomen vel verbum.
When we say “man is just,” the verb “is” is added to the predicate as a third name or verb in the affirmation. Now, “is,” like any other word, may be called a name, and thus it is a third name—that is, a word. But because, according to common usage, a word signifying time is called a “verb” rather than a “name,” Aristotle adds here, or verb, as if to say that with respect to the fact that it is a third thing, it does not matter whether it is called a name or a verb.
Peri.L2
215. Deinde cum dicit: Idcirco quatuor et cetera, concludit numerum enuntiationum.
He goes on to say: in this case, therefore, there will be four enunciations (19b22). Here he concludes to the number of the enunciations.
Peri.L2
Et primo ponit conclusionem numeri;
First, he gives the number;
Peri.L2
secundo ponit earum habitudinem, ibi: Quarum duae quidem et cetera;
second, their relationship, at: two of which will correspond in their sequence (19b23);
Peri.L2
tertio rationem numeri explicat, ibi: Dico autem quoniam est et cetera.
third, the reason for the number, at: I mean that the “is” will be added either to “just” or to “non-just" (19b24; [223]).
Peri.L2
Dicit ergo quod, quia duae sunt oppositiones quando ‘est’ tertium adiacens praedicatur, cum omnis oppositio sit inter duas enuntiationes, consequens est quod sint quatuor enuntiationes iste in quibus ‘est’ tertium adiacens praedicatur, subiecto finito non universaliter sumpto.
Therefore, he first says that since there are two oppositions when “is” is predicated as a third element in the enunciation, and since every opposition is between two enunciations, it follows that there are four enunciations in which “is” is predicated as a third element when the subject is finite and is not taken universally.
Peri.L2
Deinde cum dicit: Quarum duae quidem et cetera, ostendit habitudinem praedictarum enuntiationum ad invicem.
When he says: two of which will correspond in their sequence (19b23), he shows their relationship.
Peri.L2
Et dicit quod duae dictarum enuntiationum se habent ad affirmationem et negationem secundum consequentiam, sive secundum correlationem aut analogiam, ut in Graeco habetur, sicut privationes, aliae vero duae minime.
Two of these enunciations are related to affirmation and negation according to consequence (or according to correlation or proportion, as it is in the Greek) like privations, but the other two are not.
Peri.L2
Quod, quia breviter et obscure dictum est, diversimode est a diversis expositum.
Because this is said so briefly and obscurely, it has been explained in diverse ways.
Peri.L2
216. Ad cuius evidentiam considerandum est quod triplex nomen potest praedicari in huiusmodi enuntiationibus.
Before we take up the various explanations of this passage, there is a general point in relation to it that needs to be clarified. In this kind of enunciation, a name can be predicated in three ways.
Peri.L2
Quandoque enim praedicatur nomen finitum, secundum quod assumuntur duae enuntiationes, una affirmativa et alia negativa, scilicet: ‘Homo est iustus’ et ‘Homo non est iustus’, quae dicuntur simplices.
We can predicate a finite name and by this we obtain two enunciations, one affirmative and one negative, “man is just” and “man is not just.” These are called simple enunciations.
Peri.L2
Quandoque vero praedicatur nomen infinitum, secundum quod etiam sumuntur duae aliae, scilicet: ‘Homo est non iustus—Homo non est non iustus’, quae dicuntur infinitae.
Or, we can predicate an infinite name, and by this we obtain two other enunciations, “man is non-just” and “man is not non-just.” These are called infinite enunciations.
Peri.L2
Quandoque vero praedicatur nomen privativum, secundum quod etiam sumuntur duae aliae, scilicet ‘Homo est iniustus—Homo non est iniustus’, quae dicuntur privativae.
Finally, we can predicate a privative name, and again we will have two, “man is unjust” and “man is not unjust.” These are called privative.
Peri.L2
217. Quidam ergo sic exposuerunt quod duae enuntiationes earum quas praemiserat, scilicet illae quae sunt de infinito praedicato, se habent ad affirmationem et negationem quae sunt de praedicato finito secundum consequentiam vel analogiam, sicut privationes, id est sicut illae quae sunt de praedicato privativo; illae enim duae quae sunt de praedicato infinito se habent secundum consequentiam ad illas quae sunt de finito praedicato secundum transpositionem quandam, scilicet affirmatio ad negationem et negatio ad affirmationem: nam ‘Homo est non iustus’, quae est affirmativa de infinito praedicato, respondet secundum consequentiam negativae de praedicato finito, huic scilicet: ‘Homo non est iustus’, negativa vero de praedicato infinito, scilicet: ‘Homo non est non iustus’, affirmativae de finito praedicato, huic scilicet: ‘Homo est iustus’. Propter quod Theophrastus vocabat eas quae sunt de infinito praedicato transpositas. Et similiter etiam affirmativa de privativo praedicato respondet secundum consequentiam negativae de finito praedicato, scilicet haec: ‘Homo est iniustus’, ei quae est: ‘Homo non est iustus’, negativa vero affirmativae, scilicet haec: ‘Homo non est iniustus’, ei quae est: ‘Homo est iustus’.
Now, the passage in question has been explained by some in the following way. Two of the enunciations he has given, those with an infinite predicate, are related to the affirmation and negation of the finite predicate according to consequence or analogy, as are privations, that is, as are those with a privative predicate. For the two with an infinite predicate are related according to consequence to those with a finite predicate but in a transposed way, namely, affirmation to negation and negation to affirmation. That is, “man is non-just,” the affirmation of the infinite predicate, corresponds according to consequence to the negative of the finite predicate, that is, to “man is not just”; the negative of the infinite predicate, “man is not non-just,” corresponds to the affirmative of the finite predicate, that is, to “man is just.” Theophrastus for this reason called those with the infinite predicate “transposed.” The affirmative with a privative predicate also corresponds according to consequence to the negative with a finite predicate, that is, “man is unjust” to “man is not just”; and the negative of the privative predicate to the affirmative of the finite predicate, “man is not unjust” to “man is just.”
Peri.L2
Disponatur ergo in figura: in prima quidem linea, quae sunt de finito, scilicet: ‘Homo est iustus—Homo non est iustus’; in secunda autem linea, negativa de infinito praedicato sub affirmativa de finito et affirmativa sub negativa; in tertia vero negativa de privativo praedicato similiter sub affirmativa de finito et affirmativa sub negativa; ut patet in subscripta figura:
These enunciations can therefore be placed in a table in the following way:
Peri.L2
Simplices: homo est iustus—homo non est iustus
Simple: man is just—man is not just.
Peri.L2
Infinitae: homo non est non iustus—homo est non iustus
Infinite: man is not non-just—man is non-just.
Peri.L2
Privativae: homo non est iniustus—homo est iniustus
Privative: man is not unjust—man is unjust.
Peri.L2
Sic igitur duae, scilicet quae sunt de infinito praedicato, se habent ad affirmationem et negationem de finito praedicato sicut privationes, id est sicut illae quae sunt de privativo praedicato; sed duae aliae, quae sunt de infinito subiecto, scilicet: ‘<Non> homo est iustus—Non homo non est iustus’, manifestum est quod non similem consequentiam habent.
This makes it clear that two—those with the infinite predicate—are related to the affirmation and negation of the finite predicate in the way privations are, that is, as those that have a privative predicate. It is also evident that there are two others that do not have a similar consequence, namely, those with an infinite subject, “non-man is just” and “non-man is not just.”
Peri.L2
Et hoc modo exposuit Herminus hoc quod dicitur: duae vero minime, referens hoc ad illas quae sunt de infinito subiecto.
This is the way Herminus explained the words but two will not, that is, by referring it to enunciations with an infinite subject.
Peri.L2
Sed hoc manifeste est contra litteram: nam, cum praemisisset quatuor enuntiationes, duas scilicet de finito praedicato et duas de infinito, subiungit quasi illas subdividens: quarum duae quidem et cetera, duae vero minime; unde datur intelligi quod utraeque duae intelligantur in praemissis; illae autem quae sunt de infinito subiecto non includuntur in praemissis, sed de his postea dicetur; unde manifestum est quod de eis nunc non loquitur.
This, however, is clearly contrary to the words of Aristotle, for, after giving the four enunciations (two with a finite predicate and two with an infinite predicate), he adds: two of which, but two will not, as though he were subdividing them, which can only mean that both pairs are comprised in what he is saying. He does not include among these the ones with an infinite subject but will mention them later. It is clear, then, that he is not speaking of these here.
Peri.L2
218. Et ideo, ut Ammonius dicit, alii aliter exposuerunt, dicentes quod praedictarum quatuor propositionum duae, scilicet quae sunt de infinito praedicato, sic se habent ad affirmationem et negationem, id est ad ipsam speciem affirmationis et negationis, ut privationes, id est ut privativae affirmationes seu negationes; haec enim affirmatio: ‘Homo est non iustus’, non est simpliciter affirmatio, sed secundum quid, quasi secundum privationem affirmatio, sicut homo mortuus non est simpliciter homo, sed secundum privationem; et idem dicendum est de negativa quae est de infinito praedicato. Duae vero, quae scilicet sunt de finito praedicato, non se habent ad speciem affirmationis et negationis secundum privationem, sed simpliciter: haec enim: ‘Homo est iustus’, est simpliciter affirmativa, et haec: ‘Homo non est iustus’, est simpliciter negativa.
Since this exposition is not consonant with Aristotle’s words, others, Ammonius says, have explained this in another way. According to them, two of the four propositions—those of the infinite predicate—are related to affirmation and negation, that is, to the species itself of affirmation and negation, as privations, that is, as privative affirmations and negations. For the affirmation, “man is non-just,” is not an affirmation simply, but relatively, as though according to privation, just as a dead man is not a man simply, but according to privation. The same thing applies to the negative enunciation with an infinite predicate. However, the two enunciations having finite predicates are not related to the species of affirmation and negation according to privation, but simply, for the enunciation “man is just” is simply affirmative, and “man is not just” is simply negative.
Peri.L2
Sed nec hic sensus convenit verbis Aristotelis. Dicit enim infra: Haec igitur, quemadmodum in Resolutoriis dictum est, sic sunt disposita; ubi nihil invenitur ad hunc sensum pertinens.
But this meaning does not correspond to the words of Aristotle either, for he says further on: this, then, is the way these are arranged, as we have said in the Analytics, but there is nothing in that text pertaining to this meaning.
Peri.L2
Et ideo Ammonius, ex his quae in fine <I> Priorum dicuntur de propositionibus quae sunt de finito vel infinito vel privativo praedicato, alium sensum accipit.
Ammonius, therefore, interprets this differently and in accordance with what is said in Prior Analytics 1.46, 51b5 about propositions having a finite or infinite or privative predicate.
Peri.L2
219. Ad cuius evidentiam considerandum est quod, sicut ipse dicit, enuntiatio aliqua virtute se habet ad id de quo totum id quod in enuntiatione significatur vere praedicari potest; sicut haec enuntiatio: ‘Homo est iustus’, se habet ad omnia illa de quorum quolibet vere dici potest quod est homo iustus; similiter haec enuntiatio: ‘Homo non est iustus’, se habet ad omnia illa de quorum quolibet vere dici potest quod non est homo iustus. Secundum ergo hunc modum loquendi, manifestum est quod simplex negativa in plus est quam affirmativa infinita quae ei correspondet: nam quod sit homo non iustus vere potest dici de quolibet homine qui non habet habitum iustitiae, sed quod non sit homo iustus potest dici non solum de homine non habente habitum iustitiae, sed etiam de eo quod penitus non est homo: haec enim est vera: ‘Lignum non est homo iustus’; tamen haec est falsa: ‘Lignum est homo non iustus’; et ita negativa simplex est in plus quam affirmativa infinita, sicut etiam animal est in plus quam homo, quia de pluribus verificatur. Simili etiam ratione, negativa simplex est in plus quam affirmativa privativa, quia de eo quod non est homo non potest dici quod sit homo iniustus; sed affirmativa infinita est in plus quam affirmativa privativa: potest enim dici de puero et de quocumque homine nondum habente habitum virtutis aut vitii quod sit homo non iustus, non tamen de aliquo <eorum> vere dici potest quod sit homo iniustus. Affirmativa vero simplex in minus est quam negativa infinita, quia quod non sit homo non iustus potest dici non solum de homine iusto, sed etiam de eo quod penitus non est homo. Similiter etiam negativa privativa <in plus est quam negativa infinita>: nam quod non sit homo iniustus, potest dici non solum de homine habente habitum iustitiae et de eo quod penitus non est homo, de quorum quolibet potest dici quod non sit homo non iustus, sed ulterius potest dici de omnibus hominibus qui neque habent habitum iustitiae neque habent habitum iniustitiae.
To make Ammonius’ explanation clear, it must be noted that, as Aristotle himself says, by some power, the enunciation is related to the things of which the whole of what is signified in the enunciation can be truly predicated. The enunciation “man is just,” for example, is related to all those of which in any way “is a just man” can be truly said. So, too, the enunciation “man is not just” is related to all those of which in any way “is not a just man” can be truly said. According to this mode of speaking, it is thus evident that the simple negative is wider than the infinite affirmative which corresponds to it. Thus, “is a non-just man” can truly be said of any man who does not have the habit of justice, but “is not a just man” can be said not only of a man not having the habit of justice, but also of what is not a man at all. For example, it is true to say, “wood is not a just man,” but false to say, “wood is a non-just man.” The simple negative, then, is wider than the infinite affirmative, just as “animal” is wider than “man,” since it is true of more things. For a similar reason, the simple negative is wider than the privative affirmative, for “is an unjust man” cannot be said of what is not man. But the infinite affirmative is wider than the private affirmative, for “is a non-just man” can be truly said of a boy or of any man not yet having a habit of virtue or vice, but “is an unjust man” cannot. And the simple affirmative is narrower than the infinite negative, for “is not a non-just man” can be said not only of a just man, but also of what is not man at all. Similarly, the privative negative is wider than the infinite negative. For “is not an unjust man” can be said not only of a man having the habit of justice and of what is not man at all—of which “is not a non-just man” can be said—but over and beyond this can be said about all men who neither have the habit of justice nor the habit of injustice.
Peri.L2
220. His igitur visis, facile est exponere praesentem litteram hoc modo: Quarum, scilicet quatuor enuntiationum praedictarum, duae quidem, scilicet infinitae, se habebunt ad affirmationem et negationem, id est ad duas simplices quarum una est affirmativa et alia negativa, secundum consequentiam, id est in modo consequendi ad eas, ut privationes, id est sicut duae privativae.
With these points in mind it is easy to explain the present sentence in Aristotle. Two of which, that is, the infinites, will be related to the simple affirmation and negation according to consequence, that is, in their mode of following upon the two simple enunciations, the infinitives will be related as are privations, that is, as the two privative enunciations.
Peri.L2
Quia scilicet, sicut ad simplicem affirmativam sequitur negativa infinita et non convertitur, eo quod negativa infinita est in plus, ita etiam ad simplicem affirmativam sequitur negativa privativa, quae est in plus et non convertitur; et, sicut simplex negativa sequitur ad affirmativam infinitam, quae est in minus et non convertitur, ita etiam simplex negativa sequitur ad privativam affirmativam, quae est in minus et non convertitur. Ex quo patet quod eadem est habitudo in consequendo infinitarum ad simplices quae est etiam privativarum.
For just as the infinite negative follows upon the simple affirmative, and is not convertible with it (because the infinite negative is wider), so also the privative negative, which is wider, follows upon the simple affirmative and is not convertible. But just as the simple negative follows upon the infinite affirmative, which is narrower and is not convertible with it, so also the simple negative follows upon the privative affirmative, which is narrower and is not convertible. From this it is clear that there is the same relationship, with respect to consequence, of infinites to simple enunciations as there is of privatives.
Peri.L2
221. Sequitur: duae autem, scilicet simplices, quae relinquuntur remotis duabus, scilicet infinitis, a quatuor praemissis, minime, id est non ita se habent ad infinitas in consequendo sicut privativae se habent ad eas, quia videlicet ex una parte simplex affirmativa est in minus quam negativa infinita, sed negativa privativa est in plus quam negativa infinita; ex alia vero parte negativa simplex est in plus quam affirmativa infinita, sed affirmativa privativa est in minus quam infinita affirmativa. Sic ergo patet quod simplices non ita se habent ad infinitas in consequendo sicut privativae se habent ad infinitas.
He goes on to say: but two (19b23), namely, the simple enunciations that are left after the two infinite enunciations have been taken care of, will not, that is to say, they are not related to infinites according to consequence as privatives are related to them. On the one hand, the simple affirmative is narrower than the infinite negative, and the privative negative is wider than the infinite negative. On the other hand, the simple negative is wider than the infinite affirmative, and the privative affirmative narrower than the infinite affirmative. Thus it is clear that simple enunciations are not related to infinites in respect to consequence as privatives are related to infinites.
Peri.L2
222. Quamvis autem secundum hoc littera Philosophi subtiliter exponatur, tamen videtur esse aliquantulum expositio extorta: nam littera Philosophi videtur sonare diversas habitudines non esse attendendas respectu diversorum, sicut in praedicta expositione primo accipitur similitudo habitudinis ad simplices, postea dissimilitudo habitudinum respectu infinitarum.
But although this smoothly explains the words of the Philosopher, the explanation appears a bit forced. For the words of the Philosopher seem to say that diverse relationships will not apply in respect to diverse things. However, in the exposition we have just seen, there is first an explanation of a similitude of relationship to simple enunciations, and then an explanation of a dissimilitude of relationship in respect to infinites.
Peri.L2
Et ideo simplicior et magis conveniens litterae Aristotelis est expositio Porphyrii quam Boethius ponit, secundum quam expositionem attenditur similitudo et dissimilitudo <secundum consequentiam> affirmativarum ad negativas. Unde dicit: Quarum, scilicet quatuor praemissarum, duae quidem, scilicet affirmativae quarum una est simplex et alia infinita, se habebunt secundum consequentiam ad affirmationem et negationem, ut scilicet ad unam affirmativam sequatur alterius negativa: nam ad affirmativam simplicem sequitur negativa infinita, et ad affirmativam infinitam sequitur negativa simplex; duae vero, scilicet negativae, minime, id est non ita se habent ad affirmativas, ut scilicet ex negativis sequantur affirmativae sicut ex affirmativis sequebantur negativae. Quantum ad utrumque similiter se habent privativae sicut infinitae.
Porphyry’s simpler exposition of this passage of Aristotle, which Boethius gives, is therefore more suitable. According to Porphyry’s explanation, there is similitude and dissimilitude according to consequence of affirmatives and negatives. Thus Aristotle is saying: of which, that is, the four enunciations we are discussing, two (namely, one simple and one infinite affirmative) will be related according to consequence in regard to affirmation and negation, that is, so that the other negative follows upon one affirmative, for the infinite negative follows upon the simple affirmative and the simple negative upon the infinite affirmative. But two, namely, the negatives, will not, that is, they are not so related to affirmatives that affirmatives follow from negatives. And with respect to both, privatives are related in the same way as the infinites.
Peri.L2
223. Deinde cum dicit: Dico autem quoniam et cetera, manifestat quiddam quod supra dixerat, scilicet quod sint quatuor praedictae enuntiationes.
Then Aristotle says, I mean that the “is"(19b24). Here he shows how, under these circumstances, we get four enunciations.
Peri.L2
Loquimur enim nunc de enuntiationibus in quibus hoc verbum ‘est’ non solum praedicatur, sed adiacet alicui nomini finito vel infinito, puta secundum quod adiacet ‘iusto’, ut cum dicitur: ‘Homo est iustus’, vel secundum quod adiacet ‘non iusto’, ut cum dicitur: ‘Homo est non iustus’; et, quia in neutra harum negatio apponitur ad verbum, consequens est quod utraque sit affirmativa; omni autem affirmationi opponitur negatio, ut supra in I ostensum est; relinquitur ergo quod praedictis duabus enuntiationibus affirmativis respondet duae aliae, negationes, et sic consequens est quod sint quatuor simplices enuntiationes.
We are speaking now of enunciations in which the verb “is” is predicated as added to some finite or infinite name—for instance, as it adjoins “just” in “man is just,” or “non-just” in “man is non-just.” Now, since the negation is not applied to the verb in either of these, each is affirmative. However, there is a negation opposed to every affirmation, as was shown in the first book. Therefore, two negatives correspond to the two foresaid affirmative enunciations, making four simple enunciations.
Peri.L2
224. Deinde cum dicit: Intelligimus vero quod dicitur et cetera, manifestat quod supra dictum est per quandam figuralem descriptionem.
Then he says: the following diagram will make this clear (19b27). Here he manifests what he has said by a diagrammatic description.
Peri.L2
Dicit enim quod id quod in supra dictis dictum est intelligi potest...
For, as he says, what has been stated can be understood . . .

The Number and Relationship of Enunciations in Which the Verb “Is” Is Predicated and the Subject Is the Finite Name Taken Universally, or the Infinite Name, and of Those in Which the Adjective Verb is Predicated
Peri.L3
Similiter autem se habent, et si universalis nominis sit affirmatio;
19b32. The same is the case when the affirmation is of a name taken universally, as in the following:
Peri.L3
ut est, omnis homo iustus est;
Every man is just (Affirmation)
Peri.L3
negatio huius, non omnis est homo iustus,
Not every man is just (Negation)
Peri.L3
omnis est homo non iustus,
Every man is non-just (Affirmation)
Peri.L3
non omnis est homo non iustus.
Not every man is non-just (Negation)
Peri.L3
Sed non similiter angulares contingit veras esse; contingit autem aliquando. Hae igitur duae oppositae sunt.
19b35. But it is not possible, in the same way as in the former case, that those on the diagonal both be true; it is sometimes possible, however.
Peri.L3
Aliae autem duae ad id quod est, non homo, quasi ad subiectum aliquod additum;
19b36. These two pairs, then, are opposed; and there are two other pairs if something is added to “non-man” as a subject. Thus:
Peri.L3
ut, est iustus non homo,
Non-man is just (Affirmation)
Peri.L3
non est iustus non homo;
Non-man is not non-just (Negation)
Peri.L3
est non iustus non homo,
Non-man is not just (Negation)
Peri.L3
non est non iustus non homo.
Non-man is non-just (Affirmation)
Peri.L3
Plures autem his non erunt oppositae.
20a1. There will be no more opposites than these.
Peri.L3
Hae autem extra illas, ipsae secundum se erunt, ut nomine utentes eo, quod est non homo.
20a1. The latter, however, are separate from the former and distinct from them because of the use of “non-man” as a name.
Peri.L3
In his vero, in quibus, est, non convenit ut in eo quod est valere vel ambulare, idem faciunt sic positum, ac si, est, adderetur, ut,
20a3. In enunciations in which “is” does not join the predicate to the subject, for example when the verb “matures” or “walks” is used, the same scheme applies, and they are arranged in the same way as when “is” was added. For example:
Peri.L3
sanus est omnis homo,
Every man matures (Affirmation)
Peri.L3
non sanus est omnis homo;
Not every man matures (Negation)
Peri.L3
sanus est omnis non homo,
Every non-man matures (Affirmation)
Peri.L3
non sanus est omnis non homo.
Not every non-man matures (Negation)
Peri.L3
Non enim dicendum est, non omnis homo; sed, non, negationem ad id quod est homo addendum est; omnis enim non universalem significat, sed quoniam universaliter.
20a7. We must not say “non-every man” but must add the negation to “man”; for the “every” does not signify a universal but that a universal is taken universally.
Peri.L3
Manifestum est autem ex eo quod est, valet homo, non valet homo; valet non homo, non valet non homo. Haec enim ab illis differunt, eo quod universaliter non sunt.
20a10. This is evident from the following: “Man matures,” “Man does not mature”; “Non-man matures,” “Non-man does not mature.” For these differ from the former in that they are not taken universally; the “every” and the “no,” then, only signify that the affirmation or negation is of a name universally.
Peri.L3
Quare omnis vel nullus nihil significant aliud, nisi quoniam universaliter de nomine, vel affirmant vel negant. Ergo et caetera eadem oportet apponi.
20a14. All else in enunciations in which “is” does not join the predicate to the subject will be the same as in the case in which “is” is the second element.
Peri.L3
226. Postquam philosophus distinxit enunciationes in quibus subiicitur nomen infinitum non universaliter sumptum, hic intendit distinguere enunciationes, in quibus subiicitur nomen finitum universaliter sumptum.
Having distinguished enunciations in which the subject is an infinite name not taken universally, Aristotle now distinguishes enunciations in which the subject is a finite name taken universally.
Peri.L3
Et circa hoc tria facit:
About this he does three things.
Peri.L3
primo, ponit similitudinem istarum enunciationum ad infinitas supra positas;
He first proposes a similarity between these enunciations and the infinite enunciations already discussed;
Peri.L3
secundo, ostendit dissimilitudinem earumdem; ibi: sed non similiter etc.;
second, he shows their difference where he says, but it is not possible, in the same way as in the former case (19b35; [229]);
Peri.L3
tertio, concludit numerum oppositionum inter dictas enunciationes; ibi: hae duae igitur et cetera.
third, he concludes with the number of oppositions there are between these enunciations where he says, these two pairs, then, are opposed (19b36; [233]).
Peri.L3
Dicit ergo primo quod similes sunt enunciationes, in quibus est nominis universaliter sumpti affirmatio.
He says first, then, that enunciations in which the affirmation is of a name taken universally are similar to those already discussed.
Peri.L3
227. Quoad primum notandum est quod in enunciationibus indefinitis supra positis erant duae oppositiones et quatuor enunciationes, et affirmativae inferebant negativas, et non inferebantur ab eis, ut patet tam in expositione Ammonii, quam Porphyrii. Ita in enunciationibus in quibus subiicitur nomen finitum universaliter sumptum inveniuntur duae oppositiones et quatuor enunciationes: et affirmativae inferunt negativas et non e contra. Unde similiter se habent enunciationes supradictae, si nominis in subiecto sumpti fiat affirmatio universaliter. Fient enim tunc quatuor enunciationes: duae de praedicato finito, scilicet omnis homo est iustus, et eius negatio quae est non omnis homo est iustus; et duae de praedicato infinito, scilicet omnis homo est non iustus, et eius negatio quae est, non omnis homo est non iustus. Et quia quaelibet affirmatio cum sua negatione unam integrat oppositionem, duae efficiuntur oppositiones, sicut et de indefinitis dictum est. Nec obstat quod de enunciationibus universalibus loquens particulares inseruit; quoniam sicut supra de indefinitis et suis negationibus sermonem fecit, ita nunc de affirmationibus universalibus sermonem faciens de earum negationibus est coactus loqui. Negatio siquidem universalis affirmativae non est universalis negativa, sed particularis negativa, ut in I libro habitum est.
It is to be noted in relation to Aristotle’s first point that in indefinite enunciations there were two oppositions and four enunciations, the affirmatives inferring the negatives and not being inferred by them, as is clear in the exposition of Ammonius as well as of Porphyry. In enunciations in which the finite name universally taken is the subject there are also two oppositions and four enunciations, the affirmatives inferring the negatives and not the contrary. Hence, enunciations are related in a similar way if the affirmation is made universally of the name taken as the subject. For four enunciations will be made, two with a finite predicate—every man is just, and its negation, not every man is just—and two with an infinite predicate—every man is non-just, and its negation, not every man is non-just. And since any affirmation together with its negation makes one whole opposition, two oppositions are made, as was also said of indefinite enunciations. There might seem to be an objection to his use of particulars when speaking of universal enunciations, but this cannot be objected to, for just as in dealing with indefinite enunciations he spoke of their negations, so now in dealing with universal affirmatives he is forced to speak of their negations. The negation of the universal affirmative, however, is not the universal negative, but the particular negative, as was stated in the first book.
Peri.L3
228. Quod autem similis sit consequentia in istis et supradictis indefinitis patet exemplariter. Et ne multa loquendo res clara prolixitate obtenebretur, formetur primo figura de indefinitis, quae supra posita est in expositione Porphyrii,
A table will make it evident that the consequence is similar in these and in indefinite enunciations. And lest what is clear be made obscure by verbosity, let us first make a diagram of the indefinites posited in the last lesson, based upon the exposition of Porphyry.
Peri.L3
scilicet ex una parte ponatur affirmativa finita, et sub ea negativa infinita, et sub ista negativa privativa. Ex altera parte primo negativa finita, et sub ea affirmativa infinita, et sub ea affirmativa privativa.
Place the finite affirmative on one side and under it the infinite negative, and under this the privative negative. On the other side put the finite negative first, under it the infinite affirmative, and under this the privative affirmative.
Peri.L3
Deinde sub illa figura formetur alia figura similis illi universaliter: ponatur scilicet ex una parte universalis affirmativa de praedicato finito, et sub ea particularis negativa de praedicato infinito, et ad complementum similitudinis sub ista particularis negativa de praedicato privativo; ex altera vero parte ponatur primo particularis negativa de praedicato infinito, et sub ea universalis affirmativa de praedicato finito, et sub ista universalis affirmativa de praedicato privativo, hoc modo: (Figura).
Then, under this diagram, make another similar to it, but of universals. On one side put the universal affirmative of the finite predicate, under it the particular negative of the infinite predicate, and to complete the parallel put the particular negative of the privative predicate under this. On the other side, first put the particular negative of the infinite predicate, under it the universal affirmative of the finite predicate, and under this the universal affirmative of the privative predicate. Thus: [figure: Man is just Man is not just; Man is not non-just Man is non-just; Man is not unjust Man is unjust] [figure: Every man is just Not every man is just; Not every man is non-just Every man is non-just; Not every man is unjust Every man is unjust]
Peri.L3
Quibus ita dispositis, exerceatur consequentia semper in ista proxima figura, sicut supra in indefinitis exercita est: sive sequendo expositionem Ammonii, ut infinitae se habeant ad finitas, sicut privativae se habent ad ipsas finitas; finitae autem non se habeant ad infinitas medias, sicut privativae se habent ad ipsas infinitas: sive sectando expositionem Porphyrii, ut affirmativae inferant negativas, et non e contra. Utrique enim expositioni suprascriptae deserviunt figurae, ut patet diligenter indaganti. Similiter ergo se habent enunciationes istae universales ad indefinitas in tribus, scilicet in numero propositionum, et numero oppositionum, et modo consequentiae.
In this disposition of enunciations, the consequence always follows in the second diagram just as it followed in regard to indefinites in the first diagram. This is true if we follow the exposition of Ammonius, in which infinites are related to finites as privatives are related to the same finites, and the finites not related to the infinite middle enunciations as privatives are related to those infinites. It is equally true if we follow the exposition of Porphyry, in which affirmatives infer negatives and not vice versa. That the tables serve both expositions will be clear to one studying them. These universal enunciations, therefore, are related in like manner to indefinite enunciations in three things: the number of propositions, the number of oppositions, and the mode of consequence.
Peri.L3
229. Deinde cum dicit: sed non similiter angulares etc., ponit dissimilitudinem inter istas universales et supradictas indefinitas, in hoc quod angulares non similiter contingit veras esse.
When he says, but it is not possible (19b35), he proposes a difference between the universals and the indefinites, namely, that it is not possible for the diagonals to be true in the case of universals.
Peri.L3
Quae verba primo exponenda sunt secundum eam, quam credimus esse ad mentem Aristotelis, expositionem;
First, we will explain these words according to the exposition we believe Aristotle had in mind;
Peri.L3
deinde secundum alios.
next, according to the opinion of others.
Peri.L3
Angulares enunciationes in utraque figura suprascripta vocat eas quae sunt diametraliter oppositae, scilicet affirmativam finitam ex uno angulo, et affirmativam infinitam sive privativam ex alio angulo: et similiter negativam finitam ex uno angulo, et negativam infinitam vel privativam ex alio angulo.
Aristotle means by diagonal enunciations those that are diametrically opposed in the diagram above, namely, the finite affirmative in one corner and the infinite affirmative or the privative in the other; and the finite negative in one corner and the infinite negative or privative in the other.
Peri.L3
230. Enunciationes ergo in qualitate similes angulares vocatae, eo quod angulares, idest diametraliter distant, dissimilis veritatis sunt apud indefinitas et universales. Angulares enim indefinitae tam in diametro affirmationum, quam in diametro negationum possunt esse simul verae, ut patet in suprascripta figura indefinitarum. Et hoc intellige in materia contingenti. Angulares vero in figura universalium non sic se habent, quoniam angulares secundum diametrum affirmationum impossibile est esse simul veras in quacumque materia. Angulares autem secundum diametrum negationum quandoque possunt esse simul verae, quando scilicet fiunt in materia contingenti: in materia enim necessaria et remota impossibile est esse ambas veras. Haec est Boethii, quam veram credimus, expositio.
Enunciations that are similar in quality and called diagonal because diametrically distant are then dissimilar in truth in the case of indefinites and universals. The indefinites on the corners, both in the diagonal of affirmations and the diagonal of negations, can be simultaneously true, as is evident in the table of the indefinite enunciations. This is to be understood in regard to contingent matter. But diagonals of universals are not so related, for angulars on the diagonal of affirmations cannot be simultaneously true in any matter. Those on the diagonal of negations, however, can sometimes be true simultaneously, namely, when they are in contingent matter. In necessary and remote matter it is impossible for both of these to be true. This is the exposition of Boethius, which we believe to be the true one.
Peri.L3
231. Herminus autem, Boethio referente, aliter exponit. Licet enim ponat similitudinem inter universales et indefinitas quoad numerum enunciationum et oppositionum, oppositiones tamen aliter accipit in universalibus et aliter in indefinitis. Oppositiones siquidem indefinitarum numerat sicut et nos numeravimus, alteram scilicet inter finitas affirmativam et negativam, et alteram inter infinitas affirmativam et negativam, quemadmodum nos fecimus.
However, according to Boethius, Herminus explains this in another way. He takes the oppositions in one way in universals and in another in indefinites, although he holds that there is a likeness between universals and indefinites with respect to the number of enunciations and of oppositions. He arrives at the oppositions of indefinites we have—namely, one between the affirmative and negative finites, and the other between the affirmative and negative infinites.
Peri.L3
Universalium vero non sic numerat oppositiones, sed alteram sumit inter universalem affirmativam finitam et particularem negativam finitam, scilicet omnis homo est iustus, non omnis homo est iustus, et alteram inter eamdem universalem affirmativam finitam et universalem affirmativam infinitam, scilicet omnis homo est iustus, omnis homo est non iustus. Inter has enim est contrarietas, inter illas vero contradictio.
But he disposes the oppositions of universals in another way, taking one between the finite universal affirmative and finite particular negative—every man is just and not every man is just—and the other between the same finite universal affirmative and the infinite universal affirmative—every man is just and every man is non-just. Between the latter there is contrariety, between the former contradiction.
Peri.L3
Dissimilitudinem etiam universalium ad indefinitas aliter ponit. Non enim nobiscum fundat dissimilitudinem inter angulares universalium et indefinitarum supra differentiam quae est inter angulares universalium affirmativas et negativas, sed supra differentiam quae est inter ipsas universalium angulares inter se ex utraque parte. Format namque talem figuram, in qua ex una parte sub universali affirmativa finita, universalis affirmativa infinita est; et ex alia parte sub particulari negativa finita, particularis negativa infinita ponitur; sicque angulares sunt disparis qualitatis, et similiter indefinitarum figuram format hoc modo: (Figura).
He also proposes the dissimilarity between universals and indefinites in another way. He does not base the dissimilarity between diagonals of universals and indefinites on the difference between affirmative and negative diagonals of universals, as we do, but on the difference between the diagonals of universals on both sides among themselves. Hence he forms his diagram in this way: under the finite universal affirmative he places the infinite universal affirmative, and on the other side, under the finite particular negative the infinite particular negative. Thus the diagonals are of different quality. He also diagrams the indefinites in this way. [figure of opposition]
Peri.L3
Quibus ita dispositis, ait in hoc stare dissimilitudinem, quod angulares indefinitarum mutuo se invicem compellunt ad veritatis sequelam, ita quod unius angularis veritas suae angularis veritatem infert undecumque incipias.
With enunciations disposed in this way he says their difference is this: in indefinite enunciations, the one on the diagonal is true as a necessary consequence of the truth of the other, so that the truth of one enunciation infers the truth of its diagonal from wherever you begin.
Peri.L3
Universalium vero angulares non se mutuo compellunt ad veritatem, sed ex altera parte necessitas deficit illationis. Si enim incipias ab aliquo universalium et ad suam angularem procedas, veritas universalis non ita potest esse simul cum veritate angularis, quod compellit eam ad veritatem: quia si universalis est vera, sua universalis contraria erit falsa: non enim possunt esse simul verae. Et si ista universalis contraria est falsa, sua contradictoria particularis, quae est angularis primae universalis assumptae, erit necessario vera: impossibile est enim contradictorias esse simul falsas. Si autem incipias e converso ab aliqua particularium et ad suam angularem procedas, veritas particularis ita potest stare cum veritate suae angularis, quod tamen non necessario infert eius veritatem: quia licet sequatur: particularis est vera; ergo sua universalis contradictoria est falsa; non tamen sequitur ultra: ista universalis contradictoria est falsa; ergo sua universalis contraria, quae est angularis particularis assumpti, est vera. Possunt enim contrariae esse simul falsae.
But there is no such mutual necessary consequence in universals from the truth of one on a diagonal to the other, since the necessity of inference fails in part. If you begin from any of the universals and proceed to its diagonal, the truth of the universal cannot be simultaneous with the truth of its diagonal so as to compel it to truth. For if the universal is true, its universal contrary will be false, since they cannot be at once true; and if this universal contrary is false, its particular contradictory, which is the diagonal of the first universal assumed, will necessarily be true, since it is impossible for contradictories to be at once false. But if, conversely, you begin with a particular enunciation and proceed to its diagonal, the truth of the particular can so stand with the truth of its diagonal that it does not infer its truth necessarily. For it follows that if the particular is true, then its universal contradictory is false. But it does not follow that if this universal contradictory is false, then its universal contrary (which is the diagonal of the particular assumed) is true. For contraries can be at once false.
Peri.L3
232. Sed videtur expositio ista deficere ab Aristotelis mente quoad modum sumendi oppositiones. Non enim intendit hic loqui de oppositione quae est inter finitas et infinitas, sed de ea quae est inter finitas inter se, et infinitas inter se. Si enim de utroque modo oppositionis exponere volumus, iam non duas, sed tres oppositiones inveniemus:
But the way in which oppositions are taken in this exposition does not seem to be what Aristotle had in mind. He did not intend to speak here of the opposition between finites and infinites, but of the opposition between finites themselves and infinites themselves. For if we meant to explain each mode of opposition, there would not be two but three oppositions:
Peri.L3
primam inter finitas,
first, between finites;
Peri.L3
secundam inter infinitas,
second, between infinites;
Peri.L3
tertiam quam ipse herminus dixit inter finitam et infinitam.
and third, the one Herminus states between finite and infinite.
Peri.L3
Figura etiam quam formavit, conformis non est ei, quam Aristoteles in fine I priorum formavit, ad quam nos remisit, cum dixit: haec igitur quemadmodum in resolutoriis dictum est, sic sunt disposita. In Aristotelis namque figura, angulares sunt affirmativae affirmativis, et negativae negativis.
Even the diagram Herminus makes is not like the one Aristotle makes at the end of I Priorum, to which Aristotle himself referred us in the last lesson when he said, this, then, is the way these are arranged, as we have said in the Analytics (19b27). For in Aristotle’s diagram, affirmatives are diagonal to affirmatives and negatives to negatives.
Peri.L3
233. Deinde cum dicit: hae igitur duae etc., concludit numerum propositionum. Et potest dupliciter exponi;
Next, Aristotle says, these two pairs, then, are opposed (19b36). Here he concludes to the number of propositions. What he says here can be interpreted in two ways.
Peri.L3
primo, ut ly hae demonstret universales, et sic est sensus, quod hae universales finitae et infinitae habent duas oppositiones, quas supra declaravimus;
In the first way, these designates universals, and thus the meaning is that the finite and infinite universals have two oppositions, which we have explained above.
Peri.L3
secundo, potest exponi ut ly hae demonstret enunciationes finitas et infinitas quoad praedicatum sive universales sive indefinitas, et tunc est sensus, quod hae enunciationes supradictae habent duas oppositiones, alteram inter affirmationem finitam et eius negationem, alteram inter affirmationem infinitam et eius negationem.
In the second, these designates enunciations which are finite and infinite with respect to the predicate, whether universal or indefinite, and then the meaning is that these enunciations have two oppositions, one between the finite affirmation and its negation and the other between the infinite affirmation and its negation.
Peri.L3
Placet autem mihi magis secunda expositio, quoniam brevitas cui Aristoteles studebat, replicationem non exigebat, sed potius quia enunciationes finitas et infinitas quoad praedicatum secundum diversas quantitates enumeraverat, ad duas oppositiones omnes reducere, terminando earum tractatum, voluit.
The second exposition seems more satisfactory to me, because the brevity for which Aristotle strove allows for no repetition; hence, in terminating his treatment of the enunciations he had enumerated—those with a finite and infinite predicate according to diverse quantities—he meant to reduce all the oppositions to two.
Peri.L3
234. Deinde cum dicit: aliae autem ad id quod est etc., intendit declarare diversitatem enunciationum de tertio adiacente, in quibus subiicitur nomen infinitum.
When he says, and there are two other pairs (19b36), he shows the diversity of enunciations when “is” is added as a third element and the subject is an infinite name.
Peri.L3
Et circa hoc tria facit:
About this he does three things.
Peri.L3
primo, proponit et distinguit eas;
First, he proposes and distinguishes them;
Peri.L3
secundo, ostendit quod non dantur plures supradictis; ibi: magis autem etc.;
second, he shows that there are no more opposites than these, at: there will be no more opposites than these (20a1; [235]);
Peri.L3
tertio, ostendit habitudinem istarum ad alias; ibi: hae autem extra et cetera.
third, he shows the relationship of these to the others, at: the latter, however, are separate (20a1; [236]).
Peri.L3
Ad evidentiam primi advertendum est tres esse species enunciationum de inesse, in quibus explicite ponitur hoc verbum est.
With respect to the first point, it should be noted that there are three species of absolute enunciations in which the verb “is” is posited explicitly.
Peri.L3
Quaedam sunt, quae subiecto sive finito sive infinito nihil habent additum ultra verbum, ut, homo est, non homo est.
Some have nothing added to the subject—which can be either finite or infinite—beyond the verb, as in man is, non-man is.
Peri.L3
Quaedam vero sunt quae subiecto finito habent, praeter verbum, aliquid additum sive finitum sive infinitum, ut, homo est iustus, homo est non iustus.
Some have, besides the verb, something either finite or infinite added to a finite subject, as in man is just, man is non-just.
Peri.L3
Quaedam autem sunt quae subiecto infinito, praeter verbum, habent aliquid additum sive finitum sive infinitum, ut, non homo est iustus, non homo est non iustus.
Finally, some have, besides the verb, something either finite or infinite added to an infinite subject, as in non-man is just, non-man is non-just.
Peri.L3
Et quia de primis iam determinatum est, ideo de ultimis tractare volens, ait: aliae autem sunt, quae habent aliquid, scilicet praedicatum, additum supra verbum est, ad id quod est, non homo, quasi ad subiectum, idest ad subiectum infinitum. Dixit autem quasi, quia sicut nomen infinitum deficit a ratione nominis, ita deficit a ratione subiecti. Significatum siquidem nominis infiniti non proprie substernitur compositioni cum praedicato quam importat, est, tertium adiacens.
He has already treated the first two and now intends to take up the last ones. And there are two other pairs, he says, that have something (namely, a predicate) added to non-man beside the verb is, as if to a subject (that is, to an infinite subject). He says as if because the infinite name falls short of the notion of a subject insofar as it falls short of the notion of a name. Indeed, the signification of an infinite name is not properly submitted to composition with the predicate, which is, the third element added, introduces.
Peri.L3
Enumerat quoque quatuor enunciationes et duas oppositiones in hoc ordine, sicut in superioribus fecit. Distinguit etiam istas ex finitate vel infinitate praedicata.
Aristotle enumerates four enunciations and two oppositions in this order as he did in the former. In addition, he distinguishes these from the former finiteness and infinity.
Peri.L3
Unde primo, ponit oppositiones inter affirmativam et negativam habentes subiectum infinitum et praedicatum finitum, dicens: ut, non homo est iustus, non homo non est iustus.
First, he posits the opposition between affirmative and negative enunciations with an infinite subject and a finite predicate, non-man is just, non-man is not just.
Peri.L3
Secundo, ponit oppositionem alteram inter affirmativam et negativam, habentes subiectum infinitum et praedicatum infinitum, dicens: ut, non homo est non iustus, non homo non est non iustus.
Second, he posits another opposition between those with an infinite subject and an infinite predicate, non-man is non-just, non-man is not non-just.
Peri.L3
235. Deinde cum dicit: magis autem plures etc., ostendit quod non dantur plures oppositiones enunciationum supradictis. Ubi notandum est quod enunciationes de inesse, in quibus explicite ponitur hoc verbum est, sive secundum, sive tertium adiacens, de quibus loquimur, non possunt esse plures quam duodecim supra positae; et consequenter oppositiones earum secundum affirmationem et negationem non sunt nisi sex.
Then he says, there will be no more opposites than these (20a1). Here he points out that there are no more oppositions of enunciations than the ones he has already given. We should note, then, that there cannot be more simple enunciations than the twelve posited in which the verb “is” is explicitly set down (whether it is the second or third element added). Consequently, their oppositions according to affirmation and negation are only six.
Peri.L3
Cum enim in tres ordines divisae sint enunciationes, scilicet in illas de secundo adiacente, in illas de tertio subiecti finiti, et in illas de tertio subiecti infiniti, et in quolibet ordine sint quatuor enunciationes; fiunt omnes enunciationes duodecim, et oppositiones sex. Et quoniam subiectum earum in quolibet ordine potest quadrupliciter quantificari, scilicet universalitate, particularitate, et singularitate et indefinitione; ideo istae duodecim multiplicantur in quadraginta octo. Quater enim duodecim quadraginta octo faciunt. Nec possibile est plures his imaginari. Et licet Aristoteles nonnisi viginti harum expresserit, octo in primo ordine, octo in secundo, et quatuor in tertio, attamen per eas reliquas voluit intelligi.
For enunciations are divided into three orders: those with the second element added, those with the third element added to a finite subject, and those with the third element added to an infinite subject. Further, in any order there are four enunciations. And since their subject can be quantified in four ways in any order—namely, by universality, particularity, singularity, and indefiniteness—these twelve will be increased to forty-eight, since four times twelve is forty-eight. Nor is it possible to imagine more than these. Aristotle has only expressed twenty of these, eight in the first order, eight in the second, and four in the third, but through them he intended the rest to be understood.
Peri.L3
Sunt autem sic enumerandae et ordinandae secundum singulos ordines, ut affirmationi negatio prima ex opposito situetur, ut oppositionis intentum clarius videatur. Et sic contra universalem affirmativam non est ordinanda universalis negativa, sed particularis negativa, quae est illius negatio; et e converso, contra particularem affirmativam non est ordinanda particularis negativa, sed universalis negativa quae est eius negatio. Ad clarius autem intuendum numerum, coordinandae sunt omnes, quae sunt similis quantitatis, simul in recta linea, distinctis tamen ordinibus tribus supradictis. Quod ut clarius elucescat, in hac subscripta videatur figura: (Figura).
They are to be enumerated and disposed according to each order so that the primary negation is placed opposite an affirmation in order to make the relation of opposition more evident. Thus, the universal negative should not be ordered as opposite to the universal affirmative, but the particular negative, which is its negation. Conversely, the particular negative should not be ordered as opposite to the particular affirmative, but the universal negative, which is its negation. For a clearer look at their number, all those of similar quantity should be placed in a straight line and in the three distinct orders given above. [insert figure from https://isidore.co/aquinas/PeriHermeneias.htm#B3]
Peri.L3
Quod autem plures his non sint, ex eo patet quod non contingit pluribus modis variari subiectum et praedicatum penes finitum et infinitum, nec pluribus modis variantur finitum et infinitum subiectum. Nulla enim enunciatio de secundo adiacente potest variari penes praedicatum finitum vel infinitum, sed tantum penes subiectum quod sufficienter factum apparet. Enunciationes autem de tertio adiacente quadrupliciter variari possunt, quia aut sunt subiecti et praedicati finiti, aut utriusque infiniti, aut subiecti finiti et praedicati infiniti, aut subiecti infiniti et praedicati finiti. Quarum nullam praetermissam esse superior docet figura.
It is evident that there are no more than these, for the subject and the predicate cannot be varied in any other way with respect to finite and infinite. Nor can the finite and infinite subject be varied in any other way, for the enunciation with a second adjoining element cannot be varied with a finite and infinite predicate but only in respect to the subject. This is clear enough. But enunciations with a third adjoining element can be varied in four ways: they may have either a finite subject and predicate, or an infinite subject and predicate, or a finite subject and infinite predicate, or an infinite subject and finite predicate. These variations are all evident in the above table.
Peri.L3
236. Deinde cum dicit: hae autem extra illas etc., ostendit habitudinem harum quas in tertio ordine numeravimus ad illas, quae in secundo sitae sunt ordine, et dicit quod istae sunt extra illas, quia non sequuntur ad illas, nec e converso. Et rationem assignans subdit: ut nomine utentes eo quod est non homo, idest ideo istae sunt extra illas, quia istae utuntur nomine infinito loco nominis, dum omnes habent subiectum infinitum. Notanter autem dixit enunciationes subiecti infiniti uti ut nomine, infinito nomine, quia cum subiici in enunciatione proprium sit nominis, praedicari autem commune nomini et verbo, omne subiectum enunciationis ut nomen subiicitur.
Then, when he says, the latter, however, are separate from the former (20a1), he shows the relationship of those we have put in the third order to those in the second order. The former, he says, are distinct from the latter because they do not follow upon the latter, nor conversely. He assigns the reason when he adds: because of the use of “non-man” as a name, that is, the former are separate from the latter because the former use an infinite name in place of a name, since they all have an infinite subject. It should be noted that he says enunciations of an infinite subject use an infinite name as a name, for to be subjected in an enunciation is proper to a name but to be predicated common to a name and a verb; therefore, every subject of an enunciation is subjected as a name.
Peri.L3
237. Deinde cum dicit: in his vero in quibus est etc., determinat de enunciationibus in quibus ponuntur verba adiectiva.
Next, he takes up enunciations in which adjective verbs are posited, when he says, in enunciations in which “is” (20a3).
Peri.L3
Et circa hoc tria facit:
About this he does three things.
Peri.L3
primo, distinguit eas;
First, he distinguishes these adjective verbs;
Peri.L3
secundo, respondet cuidam tacitae quaestioni; ibi: non enim dicendum est etc.;
second, he answers an implied question, at: we must not say “non-every man” (20a7; [238]);
Peri.L3
tertio, concludit earum conditiones; ibi: ergo et caetera eadem et cetera.
third, he concludes with their conditions, at: all else in the enunciations in which “is” does not join (20a14; [241]).
Peri.L3
Ad evidentiam primi resumendum est, quod inter enunciationes in quibus ponitur est secundum adiacens, et eas in quibus ponitur est tertium adiacens talis est differentia quod in illis, quae sunt de secundo adiacente, simpliciter fiunt oppositiones, scilicet ex parte subiecti tantum variati per finitum et infinitum; in his vero, quae habent est tertium adiacens dupliciter fiunt oppositiones, scilicet et ex parte praedicati et ex parte subiecti, quia utrumque variari potest per finitum et infinitum. Unde unum ordinem tantum enunciationum de secundo adiacente fecimus, habentem quatuor enunciationes diversimode quantificatas et duas oppositiones. Enunciationes autem de tertio adiacente oportuit partiri in duos ordines, quia sunt in eis quatuor oppositiones et octo enunciationes, ut supra dictum est.
It is necessary to note here that there is a difference between enunciations in which “is” is posited as a second adjoining element and those in which it is posited as a third element. In those with “is” as a second element, oppositions are simple, that is, varied only on the part of the subject by finite and infinite. In those having “is” as a third element, oppositions are made in two ways—on the part of the predicate and on the part of the subject—for both can be varied by finite and infinite. Hence we made only one order of enunciations with “is” as the second element. It had four enunciations quantified in diverse ways, and two oppositions. But enunciations with “is” as a third element must be divided into two orders, because in them there are four oppositions and eight enunciations, as we said above.
Peri.L3
Considerandum quoque est quod enunciationes, in quibus ponuntur verba adiectiva, quoad significatum aequivalent enunciationibus de tertio adiacente, resoluto verbo adiectivo in proprium participium et est, quod semper fieri licet, quia in omni verbo adiectivo clauditur verbum substantivum. Unde idem significant ista, omnis homo currit, quod ista, omnis homo est currens. Propter quod Boethius vocat enunciationes cum verbo adiectivo de secundo adiacente secundum vocem, de tertio autem secundum potestatem, quia potest resolvi in tertium adiacens, cui aequivalet.
Enunciations with adjective verbs are made equivalent in signification to enunciations with “is” as the third element by resolving the adjective verb into its proper participle and “is,” which may always be done because a substantive verb is contained in every adjective verb. For example, “every man runs” signifies the same thing as “every man is running.” Because of this, Boethius calls enunciations having an adjective verb “enunciations of the second adjoining element according to vocal sound, but of the third adjoining element according to power.” He designates them in this manner because they can be resolved into enunciations with a third adjoining element to which they are equivalent.
Peri.L3
Quoad numerum autem enunciationum et oppositionum, enunciationes verbi adiectivi formaliter sumptae non aequivalent illis de tertio adiacente, sed aequivalent enunciationibus, in quibus ponitur est secundum adiacens. Non possunt enim fieri oppositiones dupliciter in enunciationibus adiectivis, scilicet ex parte subiecti et praedicati, sicut fiebant in substantivis de tertio adiacente, quia verbum, quod praedicatur in adiectivis, infinitari non potest. Sed oppositiones adiectivarum fiunt simpliciter, scilicet ex parte subiecti tantum variati per infinitum et finitum diversimode quantificati, sicut fieri didicimus supra in enunciationibus substantivis de secundo adiacente, eadem ducti ratione, quia praeter verbum nulla est affirmatio vel negatio, sicut praeter nomen esse potest.
With respect to the number and oppositions of enunciations, those with an adjective verb formally taken are not equivalent to those with a third adjoining element, but to those in which “is” is posited as the second element. For oppositions cannot be made in two ways in adjectival enunciations, as they are in the case of substantival enunciations with a third adjoining element—namely, on the part of the subject and predicate, because the verb which is predicated in adjectival enunciations cannot be made infinite. Hence oppositions of adjectival enunciations are made simply, that is, only by the subject quantified in diverse ways being varied by finite and infinite—as was done above in substantival enunciations with a second adjoining element for the same reason, namely, because there can be no affirmation or negation without a verb but there can be without a name.
Peri.L3
Quia autem in praesenti tractatu non de significationibus, sed de numero enunciationum et oppositionum sermo intenditur, ideo Aristoteles determinat diversificandas esse enunciationes adiectivas secundum modum, quo distinctae sunt enunciationes in quibus ponitur est secundum adiacens. Et ait quod in his enunciationibus, in quibus non contingit poni hoc verbum est formaliter, sed aliquod aliud, ut, currit, vel, ambulat, idest in enunciationibus adiectivis, idem faciunt quoad numerum oppositionum et enunciationum sic posita, scilicet nomen et verbum, ac si est secundum adiacens subiecto nomini adderetur. Habent enim et istae adiectivae, sicut illae, in quibus ponitur est, duas oppositiones tantum, alteram inter finitas, ut, omnis homo currit, omnis homo non currit, alteram inter infinitas quoad subiectum, ut, omnis non homo currit, omnis non homo non currit.
Since the present treatment is not of significations but of the number of enunciations and oppositions, Aristotle determines that adjectival enunciations are to be diversified according to the mode in which enunciations with “is” as the second adjoining element are distinguished. And he says that in enunciations in which the verb “is” is not posited formally, but some other verb is posited (such as “matures” or “walks”)—that is, in adjectival enunciations—the name and verb form the same scheme with respect to the number of oppositions and enunciations as when “is” as a second adjoining element is added to the name as a subject. For these adjectival enunciations, like the ones in which “is” is posited, have only two oppositions: one between the finites, as in “every man runs,” “not every man runs”; the other between the infinites with respect to subject, as in “every non-man runs,” “not every non-man runs.”
Peri.L3
238. Deinde cum dicit: non enim dicendum est etc., respondet tacitae quaestioni.
Then he answers an implied question when he says, we must not say “non-every man” (20a7).
Peri.L3
Et circa hoc facit duo:
About this he does two things.
Peri.L3
primo, ponit solutionem quaestionis;
First, he states the solution of the question;
Peri.L3
deinde, probat eam; ibi: manifestum est autem et cetera.
then, he proves it, at: this is evident from the following (20a10; [239]).
Peri.L3
Est ergo quaestio talis: cur negatio infinitans numquam addita est supra signo universali aut particulari, ut puta, cum vellemus infinitare istam, omnis homo currit, cur non sic infinitata est, non omnis homo currit, sed sic, omnis non homo currit? Huic namque quaestioni respondet, dicens quod quia nomen infinitabile debet significare aliquid universale, vel singulare; omnis autem et similia signa non significant aliquid universale aut singulare, sed quoniam universaliter aut particulariter; ideo non est dicendum, non omnis homo, si infinitare volumus (licet debeat dici, si negare quantitatem enunciationis quaerimus), sed negatio infinitans ad ly homo, quod significat aliquid universale, addenda est, et dicendum, omnis non homo.
The question is this: why is the negation that makes a word infinite never added to the universal or particular sign? For example, when we wish to make “every man runs” infinite, why do we do it in this way: “every non-man runs,” and not in this: “non-every man runs”? He answers the question by saying that to be capable of being made infinite, a name has to signify something universal or singular. “Every” and similar signs, however, do not signify something universal or singular, but that something is taken universally or particularly. Therefore, we should not say “non-every man” if we wish to infinitize (although it may be used if we wish to deny the quantity of an enunciation), but must add the infinitizing negation to “man,” which signifies something universal, and say “every non-man.”
Peri.L3
239. Deinde cum dicit: manifestum est autem ex eo quod est etc., probat hoc quod dictum est, scilicet quod omnis et similia non significant aliquod universale, sed quoniam universaliter tali ratione. Illud, in quo differunt enunciationes praecise differentes per habere et non habere ly omnis, est non universale aliquod, sed quoniam universaliter; sed illud in quo differunt enunciationes praecise differentes per habere et non habere ly omnis, est significatum per ly omnis; ergo significatum per ly omnis est non aliquid universale, sed quoniam universaliter. Minor huius rationis, tacita in textu, ex se clara est. Id enim in quo, caeteris paribus, habentia a non habentibus aliquem terminum differunt, significatum est illius termini. Maior vero in littera exemplariter declaratur sic. Illae enunciationes homo currit, et omnis homo currit, praecise differunt ex hoc, quod in una est ly omnis, et in altera non. Tamen non ita differunt ex hoc, quod una sit universalis, alia non universalis. Utraque enim habet subiectum universale, scilicet ly homo, sed differunt, quia in ea, ubi ponitur ly omnis, enunciatur de subiecto universaliter, in altera autem non universaliter. Cum enim dico, homo currit, cursum attribuo homini universali, sive communi, sed non pro tota humana universitate; cum autem dico, omnis homo currit, cursum inesse homini pro omnibus inferioribus significo. Simili modo declarari potest de tribus aliis, quae in textu adducuntur, scilicet, homo non currit, respectu suae universalis universaliter, omnis homo non currit: et sic de aliis. Relinquitur ergo, quod, omnis et nullus et similia signa nullum universale significant, sed tantummodo significant, quoniam universaliter de homine affirmant vel negant.
Where he says, this is evident from the following (20a10), he proves that every and similar words do not signify a universal but that a universal is taken universally. His argument is the following. That by which enunciations having or not having the every differ is not the universal; rather, they differ in that the universal is taken universally. But that by which enunciations having and not having the every differ is signified by the every. Therefore, that which is signified by the every is not a universal but that the universal is taken universally. The minor of the argument is evident, though not explicitly given in the text: that in which the having of some term differs from the not having of it, other things being equal, is the signification of that term. The major is made evident by examples. The enunciations “man matures” and “every man matures” differ precisely by the fact that in one there is an “every,” in the other not. However, they do not differ in such a way by this that one is universal, the other not universal, for both have the universal subject, “man.” They differ because in the one in which “every” is posited, the enunciation is of the subject universally, but in the other not universally. For when I say, “man matures,” I attribute maturing to “man” as universal or common, but not to man as to the whole human race; however, when I say, “every man matures,” I signify maturing to be present to man according to all the inferiors. This is evident, too, in the three other examples of enunciations in Aristotle’s text. For example, “non-man matures,” when its universal is taken universally, becomes “every non-man matures”; and so of the others. It follows, therefore, that every and no and similar signs do not signify a universal but only signify that they affirm or deny of man universally.
Peri.L3
240. Notato hic duo:
Two things should be noted here:
Peri.L3
primum est quod non dixit omnis et nullus significat universaliter, sed quoniam universaliter;
first, that Aristotle does not say “every” and “no” signify universally, but that the universal is taken universally;
Peri.L3
secundum est, quod addit, de homine affirmant vel negant.
second, that he adds, they affirm or deny of man.
Peri.L3
Primi ratio est, quia signum distributivum non significat modum ipsum universalitatis aut particularitatis absolute, sed applicatum termino distributo. Cum enim dico, omnis homo, ly omnis denotat universitatem applicari illi termino homo, ita quod Aristoteles dicens quod omnis significat quoniam universaliter, per ly quoniam insinuavit applicationem universalitatis importatam in ly omnis in actu exercito, sicut et in I posteriorum, in definitione scire applicationem causae notavit per illud verbum quoniam, dicens: scire est rem per causam cognoscere, et quoniam illius est causa.
The reason for the first is that the distributive sign does not signify the mode of universality or of particularity absolutely, but the mode applied to a distributed term. When I say “every man,” the “every” denotes that universality is applied to the term “man.” Hence, when Aristotle says “every” signifies that a universal is taken universally, by the that he conveys the application in actual exercise of the universality denoted by the “every,” just as in Posterior Analytics 1 (71b10) in the definition of “to know” (namely, to know scientifically is to know a thing through its cause and that this is its cause), he signifies by the word “that” the application of the cause.
Peri.L3
Ratio autem secundi insinuat differentiam inter terminos categorematicos et syncategorematicos. Illi siquidem ponunt significata supra terminos absolute; isti autem ponunt significata sua supra terminos in ordine ad praedicata. Cum enim dicitur, homo albus, ly albus denominat hominem in seipso absque respectu ad aliquod sibi addendum. Cum vero dicitur, omnis homo, ly omnis etsi hominem distribuat, non tamen distributio intellectum firmat, nisi in ordine ad aliquod praedicatum intelligatur. Cuius signum est, quia, cum dicimus, omnis homo currit, non intendimus distribuere hominem pro tota sua universitate absolute, sed in ordine ad cursum. Cum autem dicimus, albus homo currit, determinamus hominem in seipso esse album et non in ordine ad cursum. Quia ergo omnis et nullus, sicut et alia syncategoremata, nil aliud in enunciatione faciunt, nisi quia determinant subiectum in ordine ad praedicatum, et hoc sine affirmatione et negatione fieri nequit; ideo dixit quod nil aliud significant, nisi quoniam universaliter de nomine, idest de subiecto, affirmant vel negant, idest affirmationem vel negationem fieri determinant, ac per hoc a categorematicis ea separavit. Potest etiam referri hoc quod dixit, affirmant vel negant, ad ipsa signa, scilicet omnis et nullus, quorum alterum positive distribuit, alterum removendo.
The reason for the second is to imply the difference between categorematic and syncategorematic terms. The former apply what is signified to the terms absolutely; the latter apply what they signify to the terms in relation to the predicates. For example, in “white man,” the “white” denominates man in himself apart from any regard to something to be added; but in every man, although the “every” distributes “man,” the distribution does not confirm the intellect unless it is understood in relation to some predicate. A sign of this is that when we say “every man runs,” we do not intend to distribute “man” in its whole universality absolutely, but only in relation to “running.” When we say “white man runs,” on the other hand, we designate man in himself as “white” and not in relation to “running.” Therefore, since every and no and the other syncategorematic terms do nothing except determine the subject in relation to the predicate in the enunciation, and this cannot be done without affirmation and negation, Aristotle says that they only signify that the affirmation or negation is of a name (that is, of a subject), universally (that is, they prescribe the affirmation or negation that is being formed), and by this he separates them from categorematic terms. They affirm or deny can also be referred to the signs themselves (that is, every and no); one of these distributes positively, the other distributes by removing.
Peri.L3
241. Deinde cum dicit: ergo et caetera eadem etc., concludit adiectivarum enunciationum conditiones. Dixerat enim quod adiectivae enunciationes idem faciunt quoad oppositionum numerum, quod substantivae de secundo adiacente; et hoc declaraverat, oppositionum numero exemplariter subiuncto. Et quia ad hanc convenientiam sequitur convenientia quoad finitationem praedicatorum, et quoad diversam subiectorum quantitatem, et earum multiplicationem ex ductu quaternarii in seipsum, et si qua sunt huiusmodi enumerata; ideo concludit: ergo et caetera, quae in illis servanda erant, eadem, idest similia istis apponenda sunt.
When he says, all else in enunciations (20a14), he concludes the treatment of the conditions of adjectival enunciations. He has already stated that adjectival enunciations are the same with respect to the number of oppositions as substantival enunciations with “is” as the second element, and has clarified this by a table showing the number of oppositions. Now, since upon this conformity follows conformity both with respect to finiteness of predicates and with respect to the diverse quantity of subjects, and also—if any enunciations of this kind are enumerated—their multiplication in sets of four, he concludes, therefore, also the other things, which are to be observed in them, are to be considered the same, that is, similar to these.
Peri.L3
L. 4 (1.10, 20a16–20b11)Some Doubts About What Has Been Said Are Presented and Solved
Some Doubts About What Has Been Said Are Presented and Solved
Peri.L4
Quoniam vero contraria est negatio ei quae est, omne animal est iustum, illa quae significat quoniam, nullum animal est iustum; hae quidem manifestum est quoniam nunquam erunt, neque verae simul, neque in eodem ipso; his vero oppositae erunt aliquando: ut, non omne animal iustum est, et, aliquod animal iustum est.
20a16. Since the negation contrary to “every animal is just” is the one signifying “no animal is just,” it is evident that these will never be at once true, or in reference to the same thing, but the opposites of these will sometimes be true—that is, “not every animal is just” and “some animal is just.”
Peri.L4
Sequuntur vero eam quae est, omnis homo est non iustus, illa quae est, nullus homo est iustus; illam vero quae est, aliquis homo iustus est, opposita, quoniam, non omnis est homo non iustus. Necesse est enim aliquem esse.
20a20. Now, the enunciation “no man is just” follows upon the enunciation “every man is non-just”; and “not every man is non-just,” which is its opposite, follows upon “some man is just,” for its opposite1 must be “some man.”
Peri.L4
Manifestum est autem etiam, quod in singularibus si est verum interrogatum negare, quoniam et affirmare verum est. Ut, putasne Socrates sapiens est? Non. Socrates igitur non sapiens est. In universalibus vero non est vera, quae similiter dicitur: vera autem negativa est. Ut, putasne omnis homo sapiens est? non; omnis igitur homo non sapiens est: hoc enim falsum est: sed, non igitur omnis homo sapiens est, vera est. Haec enim opposita est; illa vero contraria.
20a23. And it is also clear with respect to the singular that if a question is asked and a negative answer is the true one, there is also a true affirmation. Take the example, “Is Socrates wise?” and the answer, “No.” Then, “Socrates is non-wise.” But in the case of universals, the affirmative inference is not true, but the negation is true. For example, in the question, “Is every man wise?” and the true answer is “no,” the inference “Then every man is non-wise” is clearly false, but “Not every man is wise” is true. The latter is the opposite, the former the contrary.
Peri.L4
Illae vero secundum infinita contra iacentes sunt nomina vel verba, ut in eo quod est, non homo, vel, non iustus, quasi negationes sine nomine et verbo esse videbuntur. Sed non sunt. Semper enim vel veram esse vel falsam necesse est negationem; qui vero dixit, non homo, nihil magis quam qui dicit, homo, sed etiam minus verus vel falsus fuit, si non aliquid addatur.
20a31. The antitheses in infinite names and verbs, as in “non-man” and “non-just,” might seem to be negations without a name or a verb; they are not, however. For the negation must always be either true or false; but the person who says “non-man” says nothing more than one who says “man,” and he is even further from saying something true or false if something is not added.
Peri.L4
Significat autem, est omnis non homo iustus, nulli illarum idem; nec huic opposita ea quae est, non est omnis non homo iustus:
20a37. Moreover, “every non-man is just” does not signify the same thing as any of the other enunciations, nor does the opposite of this, “not every non-man is just.”
Peri.L4
illa vero, quae est, omnis non iustus non homo est, illi quae est, nullus est iustus non homo, idem significat.
20a39. But “every non-man is non-just” signifies the same thing as “no non-man is just.”
Peri.L4
Transposita vero nomina et verba idem significant, ut, est albus homo, et, est homo albus.
20b1. When the names and verbs, are transposed, the enunciations signify the same thing—for example, “man is white” and “white is man.”
Peri.L4
Nam si hoc non est, eiusdem multae erunt negationes; sed ostensum est, quod una unius est: eius enim quae est, est albus homo, negatio est, non est albus homo: eius vero quae est, est homo albus, si non eadem est ei quae est, est albus homo, erit negatio, vel ea quae est, non est non homo albus, vel ea quae est, non est homo albus. Sed altera quidem est negatio eius, quae est, est non homo albus; altera vero eius quae est, est homo albus. Quare erunt duae unius. Quod igitur transposito nomine vel verbo, eadem sit affirmatio vel negatio, manifestum est.
20b3. For if this is not the case, there will be more than one negation of the same enunciation; but it has been shown that there is only one negation of one affirmation, for the negation of “man is white” is “man is not white”; and if “white is man” is not the same as “man is white,” the negation of it will be “white is not non-man” and “white is not man.” The former, however, is the negation of “white is non-man”; the latter of “man is white.” Therefore, there will be two [negations] of one [affirmation]. It is clear, therefore, that when the name and the verb are transposed, the signification of the affirmation and negation is the same.
Peri.L4
242. Postquam determinatum est de diversitate enunciationum, hic intendit removere quaedam dubia circa praedicta. Et circa hoc facit sex secundum numerum dubiorum, quae suis patebunt locis. Quia ergo supra dixerat quod in universalibus non similiter contingit angulares esse simul veras, quia affirmativae angulares non possunt esse simul verae, negativae autem sic; poterat quispiam dubitare, quae est causa huius diversitatis. Ideo nunc illius dicti causam intendit assignare talem, quia, scilicet, angulares affirmativae sunt contrariae inter se; contrarias autem in nulla materia contingit esse simul veras. Angulares autem negativae sunt subcontrariae illis oppositae; subcontrarias autem contingit esse simul veras.
Having treated the diversity of enunciations, Aristotle now answers certain questions about them. He takes up six points related to the number of difficulties, which will become evident as we come to them. Since he has said that in universal enunciations the diagonals in one case cannot be at once true but can be in another (for the diagonal affirmatives cannot be at once true but the negatives can), someone might raise a question as to the cause of this diversity. Therefore, it is his intention now to assign the cause of this: namely, that the diagonal affirmatives are contrary to each other, and contraries cannot be at once true in any matter; but the diagonal negatives are subcontraries opposed to these and can be at once true.
Peri.L4
Et circa haec duo facit:
About this, he does two things.
Peri.L4
primo, declarat conditiones contrariarum et subcontrariarum;
He first states the conditions for contraries and subcontraries.
Peri.L4
secundo, quod angulares affirmativae sint contrariae et quod angulares negativae sint subcontrariae; ibi: sequuntur vero et cetera.
Second, he shows that diagonal affirmatives are contraries and that diagonal negatives are subcontraries, at: now, the enunciation “no man is just" (20a20; [243]).
Peri.L4
Dicit ergo resumendo: quoniam in primo dictum est quod enunciatio negativa contraria illi affirmativae universali, scilicet, omne animal est iustum, est ista, nullum animal est iustum; manifestum est quod istae non possunt simul, idest in eodem tempore, neque in eodem ipso, idest de eodem subiecto esse verae. His vero oppositae, idest subcontrariae inter se, possunt esse simul verae aliquando, scilicet in materia contingenti, ut, quoddam animal est iustum, non omne animal est iustum.
By way of resumé, therefore, he says that in the first book it was said that the negative enunciation contrary to the universal affirmative every animal is just is no animal is just. It is evident that these cannot be at once true (that is, at the same time), nor of the same thing (that is, of the same subject). But the opposites of these, the subcontraries, can sometimes be at once true, namely, in contingent matter, as in some animal is just and not every animal is just.
Peri.L4
243. Deinde cum dicit: sequuntur vero etc., declarat quod angulares affirmativae supra positae sint contrariae, negativae vero subcontrariae.
When he says, now the enunciation, “no man is just” (20a20), he shows that the diagonal affirmatives previously posited are contraries, the negatives subcontraries.
Peri.L4
Et primum quidem ex eo quod universalis affirmativa infinita et universalis negativa simplex aequipollent; et consequenter utraque earum est contraria universali affirmativae simplici, quae est altera angularis. Unde dicit quod hanc universalem negativam finitam, nullus homo est iustus, sequitur aequipollenter illa universalis affirmativa infinita, omnis homo est non iustus.
First, he manifests this from the fact that the infinite universal affirmative and the simple universal negative are equal in meaning, and consequently each of them is contrary to the simple universal affirmative, which is the other diagonal. Hence, he says that the infinite universal affirmative, every man is non-just follows upon the finite universal negative, no man is just, equivalently.
Peri.L4
Secundum vero declarat ex eo quod particularis affirmativa finita et particularis negativa infinita aequipollent. Et consequenter utraque earum est subcontraria particulari negativae simplici, quae est altera angularis, ut in figura supra posita inspicere potes. Unde subdit quod illam particularem affirmativam finitam, aliquis homo est iustus, opposita sequitur aequipollenter (opposita intellige non istius particularis, sed illius universalis affirmativae infinitae), non omnis homo est non iustus. Haec enim est contradictoria eius.
Second, he shows this from the fact that the finite particular affirmative and the infinite particular negative are equal in meaning, and consequently each of these is subcontrary to the simple particular negative, which is the other diagonal. This you can see in the previous diagram. He says, then, that the opposite, not every man is non-just, follows upon the finite particular some man is just equivalently (understanding “the opposite” not of this particular, but of the infinite universal affirmative, for this is its contradictory).
Peri.L4
Ut autem clare videatur quomodo supra dictae enunciationes sint aequipollentes, formetur figura quadrata, in cuius uno angulo ponatur universalis negativa finita, et sub ea contradictoria particularis affirmativa finita; ex alia vero parte locetur universalis affirmativa infinita, et sub ea contradictoria particularis negativa infinita, noteturque contradictio inter angulares et collaterales inter se, hoc modo: (Figura).
In order to see clearly how these enunciations are equivalent, make a four-sided figure, putting the finite universal negative in one corner and under it the contradictory, the finite particular affirmative. On the other side, put the infinite universal affirmative and under it the contradictory, the infinite particular negative. Now indicate the contradiction between diagonals and the contradiction between collaterals. [insert figure]
Peri.L4
His siquidem sic dispositis, patet primo ipsarum universalium mutua consequentia in veritate et falsitate, quia si altera earum est vera, sua angularis contradictoria est falsa; et si ista est falsa, sua collateralis contradictoria, quae est altera universalis, erit vera, et similiter procedit quoad falsitatem particularium. Deinde eodem modo manifestatur mutua sequela. Si enim altera earum est vera, sua angularis contradictoria est falsa, ista autem existente falsa, sua contradictoria collateralis, quae est altera particularis erit vera; simili quoque modo procedendum est quoad falsitatem.
This arrangement makes the mutual consequence of the universals in truth and falsity evident, for if one of them is true, its diagonal contradictory is false; and if this is false, its collateral contradictory, which is the other universal, will be true. With respect to the falsity of the particulars, the procedure is the same. Their mutual consequence is made evident in the same way, for if one of them is true, its diagonal contradictory is false, and if this is false, its contradictory collateral (which is the other particular) will be true. The procedure is the same with respect to falsity.
Peri.L4
244. Sed est hic unum dubium. In I enim priorum, in fine, Aristoteles ex proposito determinat non esse idem iudicium de universali negativa et universali affirmativa infinita; et superius in hoc secundo, super illo verbo: quarum duae se habent secundum consequentiam, duae vero minime, Ammonius, Porphyrius, Boethius et sanctus Thomas dixerunt quod negativa simplex sequitur affirmativam infinitam, sed non e converso. Ad hoc dicendum est, secundum Albertum, quod negativam finitam sequitur affirmativa infinita subiecto constante; negativa vero simplex sequitur affirmativam absolute. Unde utrumque dictum verificatur, et quod inter eas est mutua consequentia cum subiecti constantia, et quod inter eas non est mutua consequentia absolute.
However, a question arises with respect to this. At the end of Prior Analytics 1 (51b5), Aristotle determines from what he has proposed that the judgment of the universal negative and the infinite universal affirmative is not the same. Furthermore, in the second book of the present work, in relation to the phrase of which two are related according to consequence, two are not, Ammonius, Porphyry, Boethius, and St. Thomas say that the simple negative follows upon the infinite affirmative and not conversely. Albert answers this latter difficulty by pointing out that the infinite affirmative follows upon the finite negative when the subject is constant, but the simple negative follows upon the affirmative absolutely. Hence both positions are verified, for with a constant subject there is a mutual consequence between them, but there is not a mutual consequence between them absolutely.
Peri.L4
Potest dici secundo, quod supra locuti sumus de infinita enunciatione quoad suum totalem significatum ad formam praedicati reductum; et secundum hoc, quia negativa finita est superior affirmativa infinita, ideo non erat mutua consequentia: hic autem loquimur de ipsa infinita formaliter sumpta. Unde s. Thomas tunc adducendo Ammonii expositionem dixit, secundum hunc modum loquendi: negativa simplex, in plus est quam affirmativa infinita. Textus vero I priorum ultra praedicta loquitur de finita et infinita in ordine ad syllogismum. Manifestum est autem quod universalis affirmativa sive finita sive infinita non concluditur nisi in primo primae. Universalis autem negativa quaecumque concluditur et in secundo primae, et primo et secundo secundae.
We could also answer this difficulty in this way. In book 2, lectio 2, we were speaking of the infinite enunciation with the whole of what it signified reduced to the form of the predicate, and according to this there was not a mutual consequence, since the finite negative is higher than the infinite affirmative. But here we are speaking of the infinite itself formally taken. Hence St. Thomas, when he introduced the exposition of Ammonius in his commentary on the above passage, said that according to this mode of speaking the simple negative is wider than the infinite affirmative. In the above mentioned text in Prior Analytics 1 (52a36), Aristotle is speaking of finite and infinite enunciations in relation to the syllogism. It is evident, however, that the universal affirmative, whether finite or infinite is only inferred in the first mode of the first figure, while any universal negative whatever is inferred in the second mode of the first figure and in the first and second modes of the second figure.
Peri.L4
245. Deinde cum dicit: manifestum est autem etc., movet secundum dubium de vario situ negationis, an scilicet quoad veritatem et falsitatem differat praeponere et postponere negationem. Oritur autem haec dubitatio, quia dictum est nunc quod non refert quoad veritatem si dicatur, omnis homo est non iustus, aut si dicatur, omnis homo non est iustus; et tamen in altera postponitur negatio, in altera praeponitur, licet multum referat quoad affirmationem et negationem. Hanc, inquam, dubitationem solvere intendens cum distinctione, respondet quod in singularibus enunciationibus eiusdem veritatis sunt singularis negatio et infinita affirmatio eiusdem, in universalibus autem non est sic. Si enim est vera negatio ipsius universalis non oportet quod sit vera infinita affirmatio universalis. Negatio enim universalis est particularis contradictoria, qua existente vera, non est necesse suam subalternam, quae est contraria suae contradictoriae esse veram. Possunt enim duae contrariae esse simul falsae. Unde dicit quod in singularibus enunciationibus manifestum est quod, si est verum negare interrogatum, idest, si est vera negatio enunciationis singularis, de qua facta est interrogatio, verum etiam est affirmare, idest, vera erit affirmatio infinita eiusdem singularis. Verbi gratia: putasne Socrates est sapiens? Si vera est ista responsio, non; Socrates igitur non sapiens est, idest, vera erit ista affirmatio infinita, Socrates est non sapiens. In universalibus vero non est vera, quae similiter dicitur, idest, ex veritate negationis universalis affirmativae interrogatae non sequitur vera universalis affirmativa infinita, quae similis est quoad quantitatem et qualitatem enunciationi quaesitae; vera autem est eius negatio, idest, sed ex veritate responsionis negativae sequitur veram esse eius, scilicet universalis quaesitae negationem, idest, particularem negativam. Verbi gratia: putasne omnis homo est sapiens? Si vera est ista responsio, non; affirmativa similis interrogatae quam quis ex hac responsione inferre intentaret est illa: igitur omnis homo est non sapiens. Haec autem non sequitur ex illa negatione. Falsum est enim hoc, scilicet quod sequitur ex illa responsione; sed inferendum est, igitur non omnis homo sapiens est. Et ratio utriusque est, quia haec particularis ultimo illata est opposita, idest contradictoria illi universali interrogatae quam respondens falsificavit; et ideo oportet quod sit vera. Contradictoriarum enim si una est falsa, reliqua est vera. Illa vero, scilicet universalis affirmativa infinita primo illata, est contraria illi eidem universali interrogatae. Non est autem opus quod si universalium altera sit falsa, quod reliqua sit vera. In promptu est autem causa huius diversitatis inter singulares et universales. In singularibus enim varius negationis situs non variat quantitatem enunciationis; in universalibus autem variat, ut patet. Ideo fit ut non sit eadem veritas negantium universalem in quarum altera praeponitur, in altera autem postponitur negatio, ut de se patet.
When he says, and it is also clear with respect to the singular (20a23), he presents a difficulty relating to the varying position of the negation, namely, whether there is a difference as to truth and falsity when the negation is a part of the predicate or a part of the verb. This difficulty arises from what he has just said, namely, that it is of no consequence as to truth or falsity whether you say every man is non-just or every man is not just; yet in one case the negation is a part of the predicate, in the other part of the copula, and this makes a great deal of difference with respect to affirmation and negation. To solve this problem Aristotle makes a distinction: in singular enunciations, the singular negation and infinite affirmation of the same subject are of the same truth, but in universals this is not so. For if the negation of the universal is true, it is not necessary that the infinite affirmation of the universal is true. The negation of the universal is the contradictory particular, but if it is true,1 it is not necessary that the subaltern, which is the contrary of the contradictory, be true, for two contraries can be at once false. Hence he says that in singular enunciations it is evident that if it is true to deny the thing asked—that is, if the negation of a singular enunciation, which has been made into an interrogation, is true—there will also be a true affirmation, namely, the infinite affirmation of the same singular will be true. For example, if the question do you think Socrates is wise? has no as a true response, then Socrates is non-wise; that is, the infinite affirmation Socrates is non-wise will be true. But in the case of universals the affirmative inference is not true—that is, from the truth of a negation to a universal affirmative question, the truth of the infinite universal affirmative (which is similar in quantity and quality to the enunciation asked) does not follow. But the negation is true—that is, from the truth of the negative response it follows that its negation is true (that is, the negation of the universal asked, which is the particular negative). Consider, for example, the question do you think every man is wise? If the response no is true, one would be tempted to infer the affirmative similar to the question asked, namely, that every man is non-wise. This, however, does not follow from the negation, for this is false as it follows from that response. Rather, what must be inferred is then not every man is wise. And the reason for both is that the particular enunciation inferred last is the opposite (that is, the contradictory) of the universal question, which, being falsified by the negative response, makes the contradictory of the universal affirmative true, for of contradictories, if one is false the other is true.
Peri.L4
246. Deinde cum dicit: illae vero secundum infinita etc., solvit tertiam dubitationem, an infinita nomina vel verba sint negationes. Insurgit autem hoc dubium, quia dictum est quod aequipollent negativa et infinita. Et rursus dictum est nunc quod non refert in singularibus praeponere et postponere negationem: si enim infinitum nomen est negatio, tunc enunciatio, habens subiectum infinitum vel praedicatum, erit negativa et non affirmativa. Hanc dubitationem solvit per interpretationem, probando quod nec nomina nec verba infinita sint negationes, licet videantur.
Next, when he says, the antitheses in infinite names and verbs (20a31), he raises the third difficulty, namely, whether infinite names or verbs are negations. This question arises from his having said that the negative and infinite are equivalent and from having just said that in singular enunciations it makes no difference whether the negative is a part of the predicate or a part of the verb. For if the infinite name is a negation, then the enunciation having an infinite subject or predicate will be negative and not affirmative. He resolves this question by an interpretation which proves that neither infinite names nor verbs are negations although they seem to be.
Peri.L4
Unde duo circa hoc facit:
About this he does two things.
Peri.L4
primo, proponit solutionem dicens: illae vero, scilicet dictiones, contraiacentes: verbi gratia: non homo, et, homo non iustus et iustus. Vel sic: illae vero, scilicet dictiones, secundum infinita, idest secundum infinitorum naturam, iacentes contra nomina et verba (utpote quae removentes quidem nomina et verba significant, ut non homo et non iustus et non currit, quae opponuntur contra ly homo ly iustus et ly currit), illae, inquam, dictiones infinitae videbuntur prima facie esse quasi negationes sine nomine et verbo ex eo quod comparatae nominibus et verbis contra quae iacent, ea removent, sed non sunt secundum veritatem. Dixit sine nomine et verbo quia nomen infinitum, nominis natura caret, et verbum infinitum verbi natura non possidet. Dixit quasi, quia nec nomen infinitum a nominis ratione, nec verbum infinitum a verbi proprietate omnino semota sunt. Unde, si negationes apparent, videbuntur sine nomine et verbo non omnino sed quasi.
First, he proposes the solution, saying, the antitheses in infinite names and verbs, that is, words contraposed such as non-man and non-just man and just man—or this may be read as, those (namely, words) corresponding to infinites, that is, corresponding to the nature of infinites, placed in opposition to names or verbs (namely, removing what the names and verbs signify, as in non-man, non-just, and non-runs, which are opposed to man, just, and runs)—would seem at first sight to be quasi-negations without name and verb, because, as related to the names and verbs before which they are placed, they remove them. However, they are not truly negations. He says without a name or a verb because the infinite name lacks the nature of a name and the infinite verb does not have the nature of a verb. He says as though because the infinite name does not fall short of the notion of the name in every way, nor the infinite verb of the nature of the verb. Hence, if it is thought that they are negations, they will be regarded as without a name or a verb, not in every way but as though they were without a name or a verb.
Peri.L4
Deinde probat distinctiones infinitas non esse negationes tali ratione. Semper est necesse negationem esse veram vel falsam, quia negatio est enunciatio alicuius ab aliquo; nomen autem infinitum non dicit verum vel falsum; igitur dictio infinita non est negatio. Minorem declarat, quia qui dixit, non homo, nihil magis de homine dixit quam qui dixit, homo. Et quoad significatum quidem clarissimum est: non homo, namque, nihil addit supra hominem, imo removet hominem. Quoad veritatis vero vel falsitatis conceptum, nihil magis profuit qui dixit, non homo, quam qui dixit, homo, si aliquid aliud non addatur, imo minus verus vel falsus fuit, idest magis remotus a veritate et falsitate, qui dixit, non homo, quam qui dixit, homo: quia tam veritas quam falsitas in compositione consistit; compositioni autem vicinior est dictio finita, quae aliquid ponit, quam dictio infinita, quae nec ponit, nec componit, idest nec positionem nec compositionem importat.
Next, he proves that infinitizing signs of separation are not negations by pointing out that it is always necessary for the negation to be true or false, since a negation is an enunciation of something separated from something. The infinite name, however, does not assert what is true or false. Therefore, the infinite word is not a negation. He manifests the minor when he says that the one who says non-man says nothing more of man than the one who says man. Clearly this is so with respect to what is signified, for non-man adds nothing beyond man; rather, it removes man. Moreover, with respect to a conception of truth or falsity, it is of no more use to say non-man than to say man if something else is not added. Rather, it is less true or false—that is, one who says non-man is more removed from truth and falsity than one who says man, for both truth and falsity depend on composition, and the finite word which posits something is closer to composition than the infinite word, which neither posits nor composes (that is, it implies neither positing nor composition).
Peri.L4
247. Deinde cum dicit: significat autem etc., respondet quartae dubitationi, quomodo scilicet intelligatur illud verbum supradictum de enunciationibus habentibus subiectum infinitum: hae autem extra illas, ipsae secundum se erunt. Et ait quod intelligitur quantum ad significati consequentiam, et non solum quantum ad ipsas enunciationes formaliter. Unde duas habentes subiectum infinitum, universalem scilicet affirmativam et universalem negativam adducens, ait quod neutra earum significat idem alicui illarum, scilicet habentium subiectum finitum. Haec enim universalis affirmativa, omnis non homo est iustus, nulli habenti subiectum finitum significat idem: non enim significat idem quod ista, omnis homo est iustus; neque quod ista, omnis homo est non iustus. Similiter opposita negatio et universalis negativa habens subiectum infinitum, quae est contrarie opposita supradictae, scilicet omnis non homo non est iustus, nulli illarum de subiecto finito significat idem. Et hoc clarum est ex diversitate subiecti in istis et in illis.
When he says, moreover, “every non-man is just” does not signify (20a37), he answers a fourth difficulty, namely, how the earlier statement concerning enunciations having an infinite subject is to be understood. The statement was that the latter, however, are separate from the former and distinct from them because of the use of “non-man” as a name. This is to be understood not just with respect to the enunciations themselves formally, but with respect to the consequence of what is signified. Hence, giving two examples of enunciations with an infinite subject, the universal affirmative and universal negative, he says that neither of these signifies the same thing as any of those, namely, of those having a finite subject. The universal affirmative every non-man is just does not signify the same thing as any of the enunciations with a finite subject, for it does not signify every man is just nor every man is non-just. Nor do the opposite negation, or the universal negative having an infinite subject which is contrarily opposed to the universal affirmative, signify the same thing as enunciations with a finite subject; that is, not every non-man is just and no non-man is just do not signify the same thing as any of those with a finite subject. This is evident from the diversity of subject in the latter and the former.
Peri.L4
248. Deinde cum dicit: illa vero quae est etc., respondet quintae quaestioni, an scilicet inter enunciationes de subiecto infinito sit aliqua consequentia. Oritur autem dubitatio haec ex eo, quod superius est inter eas ad invicem assignata consequentia. Ait ergo quod etiam inter istas est consequentia. Nam universalis affirmativa de subiecto, et praedicato infinitis et universalis negativa de subiecto infinito, praedicato vero finito, aequipollent. Ista namque, omnis non homo est non iustus, idem significat illi, nullus non homo est iustus. Idem autem est iudicium de particularibus indefinitis et singularibus similibus supradictis. Cuiuscunque enim quantitatis sint, semper affirmativa de utroque extremo infinita et negativa subiecti quidem infiniti, praedicati autem finiti, aequipollent, ut facile potes exemplis videre. Unde Aristoteles universales exprimens, caeteras ex illis intelligi voluit.
When he says, but “every non-man is non-just” signifies (20a39), he answers a fifth difficulty, namely, whether there is a consequence among enunciations with an infinite subject. This question arises from the fact that consequences were assigned among them earlier. He says, therefore, that there is a consequence even among these, for the universal affirmative with an infinite subject and predicate and the universal negative with an infinite subject but a finite predicate are equivalent—that is, every non-man is non-just signifies the same thing as no non-man is just. This is also the case in particular infinites and singulars which are similar to the ones already mentioned, for no matter what their quantity, the affirmative with both extremes infinite and the negative with an infinite subject and a finite predicate are always equivalent, as may be easily seen by examples. Hence, Aristotle, in giving the universals, intends the others to be understood from these.
Peri.L4
249. Deinde cum dicit: transposita vero nomina etc., solvit sextam dubitationem, an propter nominum vel verborum transpositionem varietur enunciationis significatio. Oritur autem haec quaestio ex eo, quod docuit transpositionem negationis variare enunciationis significationem. Aliud enim dixit significare, omnis homo non est iustus, et aliud, non omnis homo est iustus. Ex hoc, inquam, dubitatur, an similiter contingat circa nominum transpositionem, quod ipsa transposita enunciationem varient, sicut negatio transposita.
When he says, when the names and verbs are transposed (20b1), he resolves a sixth difficulty: whether the signification of the enunciation is varied because of the transposition of names or verbs. This question arises from his having shown that the transposition of the negation varies the signification of the enunciation. He said that every man is non-just does not signify the same thing as not every man is just. This raises the question as to whether a similar thing happens when we transpose names. Would this vary the enunciation as the transposed negation does?
Peri.L4
Et circa hoc duo facit:
About this he does two things.
Peri.L4
primo, ponit solutionem dicens, quod transposita nomina et verba idem significant: verbi gratia, idem significat, est albus homo, et, est homo albus, ubi est transpositio nominum. Similiter transposita verba idem significant, ut, est albus homo, et, homo albus est.
First, he states the solution, saying that transposed names and verbs signify the same thing; for instance, man is white signifies the same thing as white is man. Transposed verbs also signify the same thing, as in man is white and man white is.
Peri.L4
250. Deinde cum dicit: nam si hoc non est etc., probat praedictam solutionem ex numero negationum contradictoriarum ducendo ad impossibile, tali ratione. Si hoc non est, idest si nomina transposita diversificant enunciationem, eiusdem affirmationis erunt duae negationes; sed ostensum est in I libro, quod una tantum est negatio unius affirmationis; ergo a destructione consequentis ad destructionem antecedentis transposita nomina non variant enunciationem. Ad probationis autem consequentiae claritatem formetur figura, ubi ex uno latere locentur ambae suprapositae affirmationes, transpositis nominibus; et ex altero contraponantur duae negativae, similes illis quoad terminos et eorum positiones. Deinde, aliquantulo interiecto spatio, sub affirmativis ponatur affirmatio infiniti subiecti, et sub negativis illius negatio. Et notetur contradictio inter primam affirmationem et duas negationes primas, et inter secundam affirmationem et omnes tres negationes, ita tamen quod inter ipsam et infimam negationem notetur contradictio non vera, sed imaginaria. Notetur quoque contradictio inter tertiam affirmationem et tertiam negationem inter se. Hoc modo: (Figura).
Then he proves the solution from the number of contradictory negations when he says, for if this is not the case (20b3). He does this by a reduction to the impossible, and his reasoning is as follows. If this is not so—that is, if transposed names diversify enunciations—there will be two negations of the same affirmation. But in the first book it was shown that there is only one negation of one affirmation. Going, then, from the destruction of the consequent to the destruction of the antecedent, transposed names do not vary the enunciation. To clarify the proof of the consequent, make a figure in which both of the affirmations posited above, with the names transposed are located on one side. Put the two negatives similar to them in respect to terms and position on the opposite side. Then, leaving a little space, under the affirmatives put the affirmation with an infinite subject and under the negatives the negation of it. Mark the contradiction between the first affirmation and the first two negations and between the second affirmation and all three negations, but in the latter case mark the contradiction between it and the lowest negation as not true but imaginary. Mark, also, the contradiction between the third affirmation and negation. [insert figure]
Peri.L4
His ita dispositis, probat consequentiam Aristoteles sic. Illius affirmationis, est albus homo, negatio est, non est albus homo; illius autem secundae affirmationis, quae est, est homo albus, si ista affirmatio non est eadem illi supradictae affirmationi, scilicet, est albus homo, propter nominum transpositionem, negatio erit altera istarum, scilicet aut, non est non homo albus, aut, non est homo albus. Sed utraque habet affirmationem oppositam alia ab illa assignatam, scilicet, est homo albus. Nam altera quidem dictarum negationum, scilicet, non est non homo albus, negatio est illius quae dicit, est non homo albus; alia vero, scilicet, non est homo albus, negatio est eius affirmationis, quae dicit, est albus homo, quae fuit prima affirmatio. Ergo quaecunque dictarum negationum afferatur contradictoria illi mediae, sequitur quod sint duae unius, idest quod unius negationis sint duae affirmationes, et quod unius affirmationis sint duae negationes: quod est impossibile. Et hoc, ut dictum est, sequitur stante hypothesi erronea, quod illae affirmationes sint propter nominum transpositionem diversae.
Now we can see how Aristotle proves the consequent. The negation of the affirmation man is white is man is not white. But if the second affirmation, white is man, is not the same as man is white, because of the transposition of the names, its negation1 will be either of these two: non-man is not white, or white is not man. But each of these has another opposed affirmation than that assigned, namely, than white is man. For one of the negations, namely, non-man is not white, is the negation of non-man is white; the other, white is not man, is the negation of the affirmation man is white, which was the first affirmation. Therefore, whatever negation is given as contradictory to the middle enunciation, it follows that there are two of one—that is, two affirmations of one negation and two negations of one affirmation—which is impossible. And this, as has been said, follows upon an erroneously set up hypothesis, namely, that these affirmations are diverse because of the transposition of names.
Peri.L4
251. Adverte hic primo quod Aristoteles per illas duas negationes, non est non homo albus, et, non est homo albus, sub disiunctione sumptas ad inveniendam negationem illius affirmationis, est homo albus, caeteras intellexit, quasi diceret: aut negatio talis affirmationis acceptabitur illa quae est vere eius negatio, aut quaecunque extranea negatio ponetur; et quodlibet dicatur, semper, stante hypothesi, sequitur unius affirmationis esse plures negationes, unam veram quae est contradictoria suae comparis habentis nomina transposita, et alteram quam tu ut distinctam acceptas, vel falso imaginaris; et e contra multarum affirmationum esse unicam negationem, ut patet in opposita figura. Ex quacunque enim illarum quatuor incipias, duas sibi oppositas aspicis. Unde notanter concludit indeterminate: quare erunt duae unius.
Notice first that Aristotle has comprehended other things through these two negations, non-man is not white and white is not man, taken under disjunction to find the negation of the affirmation man is white. It is as though he said that the negation which will be taken will either be the true negation of such an affirmation or some extraneous negation. And whichever is taken, it always follows, given the hypothesis, that there are many negations of one affirmation—one which is the contradictory of it, having equal truth with the one having its name transposed, and the other which you accept as distinct, or you imagine falsely. And conversely, there is a single negation of many affirmations, as is clear in the diagram. Hence, from whichever of these four you begin, you see two opposed to it. It is significant, therefore, that Aristotle concludes indeterminately: therefore, there will be two of one.
Peri.L4
252. Nota secundo quod Aristoteles contempsit probare quod contradictoria primae affirmationis sit contradictoria secundae, et similiter quod contradictoria secundae affirmationis sit contradictoria primae. Hoc enim accepit tamquam per se notum, ex eo quod non possunt simul esse verae neque simul falsae, ut manifeste patet praeposito sibi termino singulari. Non stant enim simul aliquo modo istae duae, Socrates est albus homo, Socrates non est homo albus. Nec turberis quod eas non singulares proposuit. Noverat enim supra dictum esse in primo quae affirmatio et negatio sint contradictoriae et quae non, et ideo non fuit sollicitus de exemplorum claritate. Liquet ergo ex eo quod negationes affirmationum de nominibus transpositis non sunt diversae quod nec ipsae affirmationes sunt diversae et sic nomina et verba transposita idem significant.
Second, note that Aristotle does not consider it important to prove that the contradictory of the first affirmation is the contradictory of the second, and similarly that the contradictory of the second affirmation is the contradictory of the first. This he accepts as self-evident, since they can neither be true at the same time nor false at the same time. This is manifestly clear when a singular term is placed first, for “Socrates is a white man” and “Socrates is not a white man” cannot be maintained at the same time in any mode. You should not be disturbed by the fact that he does not propose these singulars here, for he was undoubtedly aware that he had already stated in the first book which affirmations and negations are contradictories and which are not, and for this reason felt that a careful elaboration of the examples was not necessary here. It is therefore evident that since negations of affirmations with transposed names are not diverse, the affirmations themselves are not diverse, and hence transposed names and verbs signify the same thing.
Peri.L4
253. Occurrit autem dubium circa hoc, quia non videtur verum quod nominibus transpositis eadem sit affirmatio. Non enim valet: omnis homo est animal; ergo omne animal est homo. Similiter, transposito verbo, non valet: homo est animal rationale; ergo homo animal rationale est, de secundo adiacente. Licet enim nugatio committatur, tamen non sequitur primam.
A doubt does arise, however, about the point Aristotle is making here, for it does not seem true that with transposed names the affirmation is the same. This, for example, is not valid: “Every man is an animal, therefore, every animal is a man.” Nor is the following example with a transposed verb valid: “Man is a rational animal and,” taking “is” as the second element, “therefore, ‘man animal rational is’”; for although it is nugatory as a whole combination, nevertheless it does not follow upon the first.
Peri.L4
Ad hoc est dicendum quod sicut in rebus naturalibus est duplex transmutatio, scilicet localis, scilicet de loco ad locum, et formalis de forma ad formam; ita in enunciationibus est duplex transmutatio, situalis scilicet, quando terminus praepositus postponitur, et e converso, et formalis, quando terminus, qui erat praedicatum efficitur subiectum, et e converso vel quomodolibet, simpliciter et cetera. Et sicut quandoque fit in naturalibus transmutatio pure localis, puta quando res transfertur de loco ad locum, nulla alia variatione facta; quandoque autem fit transmutatio secundum locum, non pura sed cum variatione formali, sicut quando transit de loco frigido ad locum calidum: ita in enunciationibus quandoque fit transmutatio pure situalis, quando scilicet nomen vel verbum solo situ vocali variatur; quandoque autem fit transmutatio situalis et formalis simul, sicut contingit cum praedicatum fit subiectum, vel cum verbum tertium adiacens fit secundum. Et quoniam hic intendit Aristoteles de transmutatione nominum et verborum pure situali, ut transpositionis vocabulum praesefert, ideo dixit quod transposita nomina et verba idem significant, insinuare volens quod, si nihil aliud praeter transpositionem nominis vel verbi accidat in enunciatione, eadem manet oratio. Unde patet responsio ad instantias. Manifestum est namque quod in utraque non sola transpositio fit, sed transmutatio de subiecto in praedicatum, vel de tertio adiacente in secundum. Et per hoc patet responsio ad similia.
The answer to this is as follows. Just as there is a twofold transmutation in natural things—namely, local (from place to place) and formal (from form to form)—so in enunciations there is a twofold transmutation: a positional transmutation when a term placed before is placed after (and conversely), and a formal transmutation when a term that was a predicate is made a subject (and conversely, or in whatever mode, simply, and the like). And just as in natural things sometimes a purely local transmutation is made (for instance, when a thing is transferred from place to place, with no other variation made) and sometimes a transmutation is made according to place not simply but with a formal variation (as when a thing passes from a cold place to a hot place), so in enunciations a transmutation is sometimes made which is purely positional, such as when the name and verb are varied only in vocal position, and sometimes a transmutation is made which is at once formal and positional, as when the predicate becomes the subject, or the verb which is the third element added becomes the second. Aristotle’s purpose here was to treat of the purely positional transmutation of names and verbs, as the vocabulary of the transposition indicates; when he says, then, that transposed names and verbs signify the same thing, he intends to imply that if nothing other than the transposition of name and verb takes place in the enunciation, what is said remains the same. Hence, the response to the present objection is clear, for in both examples there is not only a transposition but a transmutation of subject to predicate in one case, and from an enunciation with a third element to one with a second element in the other. The response to similar questions is evident from this.

L. 5 (1.11, 20b12–20b30)Ways in Which an Enunciation May Be Many Rather Than One
Ways in Which an Enunciation May Be Many Rather Than One
Peri.L5
At vero unum de pluribus, vel plura de uno affirmare, vel negare, si non sit unum aliquid quod ex pluribus significatur, non est affirmatio neque negatio una. Dico autem unum, non si unum nomen positum sit, non sit autem unum aliquid ex illis, ut homo est fortasse et animal et bipes et mansuetum, sed ex his unum fit, ex albo autem et homine et ambulare, non est unum; quare nec si unum aliquid de his affirmet aliquis, erit affirmatio una: sed vox quidem una, affirmationes vero multae, nec si de uno ista, sed similiter plures.
20b12. Neither the affirmation nor the negation which affirms or denies one predicate of many subjects or many predicates of one subject is one, unless something one is constituted from the many. I do not use “one” of those things which, although one name may be imposed, do not constitute something one. For example, perhaps man is “animal” and “biped” and “civilized,” but there is also something one formed from these; whereas from “white” and “man” and “walking” there is not. Consequently, if someone affirms something one of these latter there will not be one affirmation, except in vocal sound; on the contrary, there will be many affirmations. Nor will there be one affirmation if someone affirms these of one subject; in this case too there will be many.
Peri.L5
Si ergo dialectica interrogatio responsionis est petitio vel propositionis vel alterius partis contradictionis, propositio vero unius contradictionis est pars, non erit una responsio ad haec. Neque enim interrogatio una, nec si sit vera.
20b22. In fact, if dialectical interrogation is a request for an answer—that is, either for the admission of a premise or one part of a contradiction (and a premise is a part of one contradiction)—there would not be one answer in reference to the above predicates. There would not be one answer even if there is a true answer, for there would not be a single question.
Peri.L5
Dictum est autem de his in Topicis. Simul autem manifestum est, quod nec hoc ipsum, quid est, dialectica interrogatio est. Oportet enim datum esse ex interrogatione eligere, utram velit contradictionis partem enunciare: sed oportet interrogantem determinare utrum hoc sit homo, an non hoc.
20b26. But we have spoken about these things in Topics 8.7. At the same time, it is clear that the question “What is it?” is not a dialectical one. For the dialectical interrogation must provide for choosing whichever part of a contradiction one wishes to enunciate. For this the interrogator must specifically word the question so that the parts of the contradiction are clear; for example, by asking whether man is this or not.
Peri.L5
254. Postquam Aristoteles determinavit diversitatem enunciationis unius provenientem ex additione negationis infinitatis, hic intendit determinare quid accidat enunciationi ex hoc quod additur aliquid subiecto vel praedicato tollens eius unitatem.
After the Philosopher has treated the diversity in an enunciation arising from the addition of the infinite negation, he explains what happens to an enunciation when something is added to the subject or predicate which takes away its unity.
Peri.L5
Et circa hoc duo facit:
About this he does two things.
Peri.L5
quia primo, determinat diversitatem earum;
He first determines their diversity;
Peri.L5
secundo, consequentias earum; ibi: quoniam vero haec quidem et cetera.
second, he proves that all the enunciations are many, at: some things predicated separately (20b31; [262]).
Peri.L5
Circa primum duo facit:
About the first he does two things.
Peri.L5
primo, ponit earum diversitatem;
First, he outlines their diversity;
Peri.L5
secundo, probat omnes enunciationes esse plures; ibi: si ergo dialectica et cetera.
second, he determines their consequences, at: in fact, if dialectical interrogation (20b22; [258]).
Peri.L5
Dicit ergo quoad primum, resumendo quod in primo dictum fuerat, quod affirmare vel negare unum de pluribus, vel plura de uno, si ex illis pluribus non fit unum, non est enunciatio una affirmativa vel negativa. Et declarando quomodo intelligatur unum debere esse subiectum aut praedicatum, subdit quod unum dico non si nomen unum impositum sit, idest ex unitate nominis, sed ex unitate significati. Cum enim plura conveniunt in uno nomine, ita quod ex eis non fiat unum illius nominis significatum, tunc solum vocis unitas est. Cum autem unum nomen pluribus impositum est, sive partibus subiectivis, sive integralibus, ut eadem significatione concludat, tunc et vocis et significati unitas est, et enunciationis unitas non impeditur.
He begins by taking up something he said in the first book: there is not one affirmative enunciation nor one negative enunciation when one thing is affirmed or denied of many or many of one, if one thing is not constituted from the many. And he explains what he means by the subject or predicate having to be one where he says, I do not use “one” of those things which, although one name may be imposed, do not constitute something one (20b12), that is, a subject or predicate is one not from the unity of the name, but from the unity of what is signified. For when many things are brought together under one name in such a way that what is signified by that name is not one, then the unity is only one of vocal sound. But when one name has been imposed for many, whether for subjective or for integral parts, so that it encloses them in the same signification, then there is unity both of vocal sound and what is signified. In the latter case, unity of the enunciation is not impeded.
Peri.L5
255. Secundum quod subiungit: ut homo est fortasse animal et mansuetum et bipes obscuritate non caret. Potest enim intelligi ut sit exemplum ab opposito, quasi diceret: unum dico non ex unitate nominis impositi pluribus ex quibus non fit tale unum, quemadmodum homo est unum quoddam ex animali et mansueto et bipede, partibus suae definitionis. Et ne quis crederet quod hae essent verae definitionis nominis partes, interposuit, fortasse.
Then he adds, for example, perhaps man is “animal” and “biped” and “civilized" (20b12). This, however, is obscure, for it can be understood as an example of the opposite, as if he were saying, I do not mean by “one” such a “one” as the unity of the name imposed upon many from which one thing is not constituted, for instance, “man” as “one” from the parts of the definition, “animal” and “civilized” and “biped.” And to prevent anyone from thinking these are true parts of the definition of the name he interposes perhaps.
Peri.L5
Porphyrius autem, Boethio referente et approbante, separat has textus particulas, dicens quod Aristoteles hucusque declaravit enunciationem illam esse plures, in qua plura subiicerentur uni, vel de uno praedicarentur plura, ex quibus non fit unum. In istis autem verbis: ut homo est fortasse etc., intendit declarare enunciationem aliquam esse plures, in qua plura ex quibus fit unum subiiciuntur vel praedicantur; sicut cum dicitur, homo est animal et mansuetum et bipes, copula interiecta, vel morula, ut oratores faciunt. Ideo autem addidisse aiunt, fortasse, ut insinuaret hoc contingere posse, necessarium autem non esse.
Porphyry, however, who is referred to with approval by Boethius, separates these parts of the text. He says Aristotle first states that that enunciation is many in which many are subjected to one (or many are predicated of one) when one thing is not constituted from these. And when he says, for example, perhaps man is, he intends to show that an enunciation is many when many things are subjected or predicated from which one thing is constituted, as in the example man is an animal and civilized and biped, with interjected copulas or a pause such as orators make. They say that he added perhaps to imply that this could happen, but it need not.
Peri.L5
256. Possumus in eamdem Porphyrii, Boethii et Alberti sententiam incidentes subtilius textum introducere, ut quatuor hic faciat.
While agreeing with the opinion of Porphyry, Boethius, and Albert, we think a more subtle construction can be made of the text. According to it, Aristotle makes four points here.
Peri.L5
Et primo quidem, resumit quae sit enunciatio in communi dicens quod enunciatio plures est, in qua unum de pluribus, vel plura de uno enunciantur. Si tamen ex illis pluribus non fit unum, ut in primo dictum et expositum fuit.
First, he reviews what an enunciation is in general when he says that the enunciation is many in which one is enunciated of many or many of one. This is unless something one is constituted from the many, as he stated and explained in the first book.
Peri.L5
Deinde dilucidat illum terminum de uno, sive unum, dicens: dico autem unum, idest, unum nomen voco, non propter unitatem vocis, sed significationis, ut supra dictum est.
Second, he clarifies the term “one” when he says, I do not use “one” of those things, that is, I call a name “one” not by reason of the unity of vocal sound, but of signification, as was said above.
Peri.L5
Deinde tertio, dividendo declarat, et declarando dividit, quot modis contingit unum nomen imponi pluribus ex quibus non fit unum, ut ex hoc diversitatem enunciationis multiplicis insinuet.
Third, he manifests by dividing and divides by manifesting the number of ways in which one name may be imposed on many things from which one thing is not constituted. From this he implies the diversity of the multiple enunciation.
Peri.L5
Et ponit duos modos,
And he posits two ways.
Peri.L5
quorum prior est, quando unum nomen imponitur pluribus ex quibus fit unum, non tamen in quantum ex eis fit unum. Tunc enim, licet materialiter et per accidens loquendo nomen imponatur pluribus ex quibus fit unum, formaliter tamen et per se loquendo nomen unum imponitur pluribus, ex quibus non fit unum: quia imponitur eis non in quantum ex eis est unum, ut fortasse est hoc nomen, homo, impositum ad significandum animal et mansuetum et bipes, idest, partes suae definitionis, non in quantum adunantur in unam hominis naturam per modum actus et potentiae, sed ut distinctae sint inter se actualitates. Et insinuavit quod accipit partes definitionis ut distinctas per illam coniunctionem, et per illud quoque adversative additum: sed si ex his unum fit, quasi diceret, cum hoc tamen stat quod ex eis unum fit. Addidit autem, fortasse, quia hoc nomen, homo, non est impositum ad significandum partes sui definitivas, ut distinctae sunt. Sed si impositum esset aut imponeretur, esset unum nomen pluribus impositum ex quibus non fit unum.
First, when one name is imposed upon many things from which one thing is constituted, but not as one thing is constituted from them. In this case, materially and accidentally speaking, the name is imposed on many from which one thing is constituted, but it is formally and per se imposed on many from which one thing is not constituted. For it is not imposed upon them in the respect in which they constitute one thing, as perhaps the name “man” is imposed to signify “animal” and “civilized” and “biped” (which are parts of its definition) not as they are united in the one nature of man in the mode of act and potency, but as they are themselves distinct actualities. Aristotle implies that he is taking these parts of the definition as distinct by the conjunctions and by also adding adversatively, but if there is something one formed from these, as if to say, when, however, it holds that one thing is constituted from these. He adds perhaps because the name man is not imposed to signify its definitive parts as they are distinct. But if it had been so imposed or were imposed, it would be one name imposed on many things from which no one thing is constituted.
Peri.L5
Et quia idem iudicium est de tali nomine, et illis pluribus; ideo similiter illae plures partes definitivae possunt dupliciter accipi.
And since the judgment with respect to such a name and those many things is the same, the many definitive parts can also be taken in two ways.
Peri.L5
Uno modo, per modum actualis et possibilis, et sic unum faciunt; et sic formaliter loquendo vocantur plura, ex quibus fit unum, et pronunciandae sunt continuata oratione, et faciunt enunciationem unam dicendo, animal rationale mortale currit. Est enim ista una sicut et ista, homo currit.
First, in the mode of the actual and possible, and thus they constitute one thing; are formally called “many from which one thing is constituted”; are to be pronounced in continuous speech; and make one enunciation, such as “a mortal rational animal is running.” For this is one enunciation, just as is “man is running.”
Peri.L5
Alio modo, accipiuntur praedictae definitionis partes ut distinctae sunt inter se actualitates, et sic non faciunt unum: ex duobus enim actibus ut sic, non fit unum, ut dicitur VII metaphysicae; et sic faciunt enunciationes plures et pronunciandae sunt vel cum pausa, vel coniunctione interposita, dicendo, homo est animal et mansuetum et bipes; sive, homo est animal, mansuetum, bipes, rhetorico more. Quaelibet enim istarum est enunciatio multiplex. Et similiter ista, Socrates est homo, si homo est impositum ad illa, ut distinctae actualitates sunt, significandum.
In the second way, the foresaid parts of the definition are taken as they are distinct actualities, and thus they do not constitute one thing, for one thing is not constituted from two acts as such, as Aristotle says in Metaphysics 7.13 (1039a5). In this case they constitute many enunciations and are pronounced either with conjunctions interposed or with a pause in the rhetorical manner, for example, man is an animal and civilized and biped or man is animal, civilized, biped. Each of these is a multiple enunciation, and so is the enunciation, “Socrates is a man,” if “man” is imposed to signify “animal,” “civilized,” and “biped” as they are distinct actualities.
Peri.L5
Secundus autem modus, quo unum nomen impositum est pluribus ex quibus non fit unum, subiungitur, cum dicit: ex albo autem et homine et ambulante etc., idest, alio modo hoc fit, quando unum nomen imponitur pluribus, ex quibus non potest fieri unum, qualia sunt: homo, album, et ambulans. Cum enim ex his nullo modo possit fieri aliqua una natura, sicut poterat fieri ex partibus definitivis, clare liquet quod nomen aliquod si eis imponeretur, esset nomen non unum significans, ut in primo dictum fuit de hoc nomine, tunica, imposito homini et equo.
Aristotle takes up the second way in which one name is imposed on many from which one thing is not constituted where he says, whereas from “white” and “man” and “walking” there is not. Since in no way can any one nature be constituted from man, white, and walking (as there can be from the definitive parts), it is evident that if a name were imposed on these it would be a name that does not signify one thing, as was said in the first book of the name “cloak” imposed for man and horse.
Peri.L5
257. Habemus ergo enunciationis pluris seu multiplicis duos modos, quorum, quia uterque fit dupliciter, efficiuntur quatuor modi.
We have, therefore, two modes of the many (that is, the multiple) enunciation, and since both are constituted in two ways, there will be four modes:
Peri.L5
Primus est, quando subiicitur vel praedicatur unum nomen impositum pluribus, ex quibus fit unum, non in quantum sunt unum;
first, when one name imposed on many from which one thing is constituted is subjected or predicated as though the name stands for many;
Peri.L5
secundus est, quando ipsa plura ex quibus fit unum, in quantum sunt distinctae actualitates, subiiciuntur vel praedicantur;
second, when the many from one which one thing is constituted are subjected or predicated as distinct actualities;
Peri.L5
tertius est, quando ibi est unum nomen impositum pluribus ex quibus non fit unum;
third, when one name is imposed for a many from which nothing one is constituted;
Peri.L5
quartus est, quando ista plura ex quibus non fit unum, subiiciuntur vel praedicantur.
the fourth, when many which do not constitute one thing are subjected or predicated.
Peri.L5
Et notato quod cum enunciatio secundum membra divisionis illius, qua divisa est, in unam et plures, quadrupliciter variari possit, scilicet cum unum de uno praedicatur, vel unum de pluribus, vel plura de uno, vel plura de pluribus; postremum sub silentio praeterivit, quia vel eius pluralitas de se clara est, vel quia, ut inquit Albertus, non intendebat nisi de enunciatione, quae aliquo modo una est, tractare.
Note that the enunciation, according to the members of the division by which it has been divided into one and many, can be varied in four ways: one is predicated of one, one of many, many of one, and many of many. Aristotle has not spoken of the last one either because its plurality is clear enough or because, as Albert says, he only intends to treat of the enunciation which is one in some way.
Peri.L5
Demum concludit totam sententiam, dicens: quare nec si aliquis affirmet unum de his pluribus, erit affirmatio una secundum rem: sed vocaliter quidem erit una, significative autem non una, sed multae fient affirmationes. Nec si e converso de uno ista plura affirmabuntur, fiet affirmatio una. Ista namque, homo est albus, ambulans et musicus, importat tres affirmationes, scilicet, homo est albus et est ambulans et est musicus, ut patet ex illius contradictione. Triplex enim negatio illi opponitur correspondens triplici affirmationi positae.
Finally, he concludes with this summary: consequently, if someone affirms something one of these latter there will not be one affirmation, except in vocal sound; on the contrary, there will be many affirmations. Nor will there be one affirmation if someone affirms these of one subject; in this case too there will be many. For example, “man is white, walking, and musical” implies three affirmations, namely, “man is white” and “is walking” and “is musical.” This is clear from its contradiction, for a threefold negation is opposed to it, corresponding to the threefold affirmation.
Peri.L5
258. Deinde cum dicit: si ergo dialectica etc., probat a posteriori supradictas enunciationes esse plures.
Then, when he says, in fact, if dialectical interrogation is a request for an answer (20b22), he proves a posteriori that the foresaid enunciations are many.
Peri.L5
Circa quod duo facit:
About this he does two things.
Peri.L5
primo, ponit rationem ipsam ad hoc probandum per modum consequentiae;
First, he states an argument to prove this by way of the consequent;
Peri.L5
deinde probat antecedens dictae consequentiae; ibi: dictum est autem de his et cetera.
then he proves the antecedent of the given consequent where he says, but we have spoken about these things in Topics 8.7 (20b26; [261]).
Peri.L5
Quoad primum talem rationem inducit. Si interrogatio dialectica est petitio responsionis, quae sit propositio vel altera pars contradictionis, nulli enunciationum supradictarum interrogative formatae erit responsio una; ergo nec ipsa interrogatio est una, sed plures. Cuius rationis primo ponit antecedens: si ergo et cetera.
Now if dialectical questioning is a request for an answer—either a proposition or one part of a contradiction—none of the foresaid enunciations, put in the form of a question, will have one answer. Therefore, the question is not one, but many. Aristotle first states the antecedent of this argument, at: if dialectical interrogation is a request for an answer (20b22).
Peri.L5
Ad huius intelligendos terminos nota quod idem sonant enunciatio, interrogatio et responsio. Cum enim dicitur, caelum est animatum, in quantum enunciat praedicatum de subiecto, enunciatio vocatur; in quantum autem quaerendo proponitur, interrogatio; ut vero quaesito redditur, responsio appellatur. Idem ergo erit probare non esse responsionem unam, et interrogationem non esse unam, et enunciationem non esse unam.
To understand this it should be noted that an enunciation, a question, and an answer sound the same. For when we say, “The region of heaven is animated,” we call it an enunciation inasmuch as it enunciates a predicate of a subject, but when it is proposed to obtain an answer we call it an interrogation, and as applied to what was asked we call it a response. Therefore, to prove that there is not one response or one question or one enunciation will be the same thing.
Peri.L5
Adverte secundo interrogationem esse duplicem.
It should also be noted that interrogation is twofold.
Peri.L5
Quaedam enim est utram partem contradictionis eligendam proponens; et haec vocatur dialectica, quia dialecticus habet viam ex probabilibus ad utramque contradictionis partem probandam.
One proposes either of the two parts of a contradiction to choose from. This is called “dialectical interrogation” because the dialectician knows the way to prove either part of a contradiction from probable positions.
Peri.L5
Altera vero determinatam ad unum responsionem exoptat; et haec est interrogatio demonstrativa, eo quod demonstrator in unum determinate tendit.
The other kind of interrogation seeks one determinate response. This is the demonstrative interrogation, for the demonstrator proceeds determinately toward a single alternative.
Peri.L5
Considera ulterius quod interrogationi dialecticae dupliciter responderi potest.
Note, finally, that it is possible to reply to a dialectical question in two ways.
Peri.L5
Uno modo, consentiendo interrogationi, sive affirmative sive negative; ut si quis petat, caelum est animatum? Et respondeatur, est; vel, Deus non movetur? Et respondeatur, non: talis responsio vocatur propositio.
We may consent to the question either affirmatively or negatively. For example, when someone asks, “Is the region of heaven animated?” we may respond, “It is,” or to the question “Is not God moved?” we may say, “No.” Such a response is called a proposition.
Peri.L5
Alio modo, potest responderi interimendo; ut si quis petat, caelum est animatum? Et respondeatur, non; vel Deus non movetur? Et respondeatur, movetur: talis responsio vocatur contradictionis altera pars, eo quod affirmationi negatio redditur et negationi affirmatio.
The second way of replying is by destroying. For example, when someone asks “Is the region of heaven animated?” we may respond, “No,” or to the question, “Is not God moved?” we may respond, “He is moved.” Such a response is called “the other part of a contradiction,” because a negation is given to an affirmation and an affirmation to a negation.
Peri.L5
Interrogatio ergo dialectica est petitio annuentis responsionis, quae est propositio, vel contradicentis, quae est altera pars contradictionis secundum supradictam Boethii expositionem.
Dialectical interrogation, then, according to the exposition just given (which is that of Boethius) is a request for an admission (which is a proposition) or a denial (which is one part of a contradiction).
Peri.L5
259. Deinde subdit probationem consequentiae, cum ait: propositio vero unius contradictionis est et cetera. Ubi notandum est quod si responsio dialectica posset esse plures, non sequeretur quod responsio enunciationis multiplicis non posset esse dialectica; sed si responsio dialectica non potest esse nisi una enunciatio, tunc recte sequitur quod responsio enunciationis pluris, non est responsio dialectica, quae una est. Notandum etiam quod si enunciatio aliqua plurium contradictionum pars est, una non esse comprobatur: una enim uni tantum contradicit. Si autem unius solum contradictionis pars est, una est eadem ratione, quia scilicet unius affirmationis unica est negatio, et e converso. Probat ergo Aristoteles consequentiam ex eo quod propositio, idest responsio dialectica unius contradictionis est, idest una enunciatio est affirmativa vel negativa. Ex hoc enim, ut iam dictum est, sequitur quod nullius enunciationis multiplicis sit responsio dialectica, et consequenter nec una responsio sit. Nec praetereas quod cum propositionem, vel alteram partem contradictionis, responsionemque praeposuerit dialecticae interrogationis, de sola propositione subiunxit, quod est una; quod ideo fecit, quia illius alterius vocabulum ipsum unitatem praeferebat. Cum enim alteram contradictionis partem audis, unam affirmationem vel negationem statim intelligis. Adiunxit autem antecedenti ly ergo, vel insinuans hoc esse aliunde sumptum, ut postmodum in speciali explicabit, vel, permutato situ, notam consequentiae huius inter antecedens et consequens locandam, antecedenti praeposuit; sicut si diceretur, si ergo Socrates currit, movetur; pro eo quod dici deberet, si Socrates currit, ergo movetur. Sequitur deinde consequens: non erit una responsio ad hoc; et infert principalem conclusionem subdens, quod neque una erit interrogatio et cetera. Si enim responsio non potest esse una, nec interrogatio ipsa una erit.
He adds the proof of the consequent when he says, and a premise is a part of one contradiction (20b22). In relation to this it should be noted that if a dialectical response could be many, it would not follow that a response to a multiple enunciation would not be dialectical. However, if the dialectical response can only be one enunciation, then it follows that a response to a plural enunciation is not a dialectical response, for it is one.1 It should also be noted that if an enunciation is a part of many contradictions, it is thereby proven not to be one, for one contradicts only one. But if an enunciation is a part of only one contradiction, it is one by the same reasoning, namely, because there is only one negation of one affirmation, and conversely. Hence Aristotle proves the consequent from the fact that the proposition (that is, the dialectical response), is a part of one contradiction (that is, it is one affirmative or one negative enunciation). It follows from this, as has been said, that there is no dialectical response of a multiple enunciation, and consequently not one response. It should not be overlooked that when he designates a proposition or one part of a contradiction as the response to a dialectical interrogation, it is only of the proposition that he adds that it is one, because the very wording shows the unity of the other. For when you hear one part of a contradiction, you immediately understand one affirmation or negation. He puts the therefore with the antecedent, either implying that this is taken from another place and he will explain in particular afterward, or having changed the structure, he places the sign of the consequent, which should be between the antecedent and consequent, before the antecedent, as when one says, “Therefore, if Socrates runs, he is moved,” for “If Socrates runs, therefore he is moved.” Then the consequent follows that there will not be one answer to this, and the inference of the principal conclusion, for there would not be a single question. For if the response cannot be one, the question will not be one.
Peri.L5
260. Quod autem addidit: nec si sit vera, eiusmodi est. Posset aliquis credere, quod licet interrogationi pluri non possit dari responsio una, quando id de quo quaestio fit non potest de omnibus illis pluribus affirmari vel negari (ut cum quaeritur, canis est animal? Quia non potest vere de omnibus responderi, est, propter caeleste sidus, nec vere de omnibus responderi, non est, propter canem latrabilem, nulla possit dari responsio una); attamen quando id quod sub interrogatione cadit potest vere de omnibus affirmari aut negari, tunc potest dari responsio una; ut si quaeratur, canis est substantia? Quia potest vere de omnibus responderi, est, quia esse substantiam omnibus canibus convenit, unica responsio dari possit. Hanc erroneam existimationem removet dicens: nec si sit vera, idest, et dato quod responsio data enunciationi multiplici de omnibus verificetur, nihilominus non est una, quia unum non significat, nec unius contradictionis est pars, sed plures responsio illa habet contradictorias, ut de se patet.
He adds, even if there is a true answer (20b22), because someone might think that although one response cannot be given to a plural interrogation when the question concerns something that cannot be affirmed or denied of all of the many—for example, when someone asks, “Is a dog an animal?” no one response can be given, for we cannot truly say of every dog that it is an animal because of the star by that name, nor can we truly say of every dog that it is not an animal, because of the barking dog—nevertheless one response could be given when that which falls under the interrogation can be truly said of all. For example, when someone asks, “Is a dog a substance?” a single response can be given because it can truly be said of every dog that it is a substance, for to be a substance belongs to all dogs. Aristotle adds the phrase, even if there is a true answer, to remove such an erroneous judgment. For even if the response to the multiple enunciation is verified of all, it is nonetheless not one, since it does not signify one thing, nor is it a part of one contradiction. Rather, as is evident, this response has many contradictories.
Peri.L5
261. Deinde cum dicit: dictum est autem de his in Topicis etc., probat antecedens dupliciter:
Where he says, but we have spoken about these things in Topics 8.7 (20b26), he proves the antecedent in two ways.
Peri.L5
primo, auctoritate eorum quae dicta sunt in Topicis;
First, he proves it on the basis of what was said in the Topics;
Peri.L5
secundo, a signo.
second, by a sign.
Peri.L5
Et circa hoc duo facit.
About this he does two things.
Peri.L5
Primo, ponit ipsum signum, dicens: quod similiter etc., cum auctoritate topicorum, manifestum est, scilicet, antecedens assumptum, scilicet quod dialectica interrogatio est petitio responsionis affirmativae vel negativae. Quoniam nec ipsum quid est, idest ex eo quod nec ipsa quaestio quid est, est interrogatio dialectica: verbi gratia; si quis quaerat, quid est animal? Talis non quaerit dialectice.
First, he gives the sign, saying, at the same time, it is clear that the question (20b26). That is, given the doctrine in the Topics, it is clear (namely, assuming the antecedent that the dialectical interrogation is a request for an affirmative or negative response) that the question “What is it?” is not a dialectical interrogation. For instance, when someone asks, “What is an animal?” he does not interrogate dialectically.
Peri.L5
Deinde subiungit probationem assumpti, scilicet quod ipsum quid est, non est quaestio dialectica; et intendit quod quia interrogatio dialectica optionem respondenti offerre debet, utram velit contradictionis partem, et ipsa quaestio quid est talem libertatem non proponit (quia cum dicimus, quid est animal? Respondentem ad definitionis assignationem coarctamus, quae non solum ad unum determinata est, sed etiam omni parte contradictionis caret, cum nec esse, nec non esse dicat); ideo ipsa quaestio quid est, non est dialectica interrogatio. Unde dicit: oportet enim ex data, idest ex proposita interrogatione dialectica, hunc respondentem eligere posse utram velit contradictionis partem, quam contradictionis utramque partem interrogantem oportet determinare, idest determinate proponere, hoc modo: utrum hoc animal sit homo an non: ubi evidenter apparet optionem respondenti offerri. Habes ergo pro signo cum quaestio dialectica petat responsionem propositionis, vel alterius contradictionis partem, elongationem quaestionis quid est a quaestionibus dialecticis.
Second, he gives the proof of what was assumed, namely, that the question “What is it?” is not a dialectical question. He states that a dialectical interrogation must offer to the one responding the option of whichever part of the contradiction he wishes. The question “What is it?” does not offer such liberty, for in saying “What is an animal?” the one responding is forced to assign a definition, and a definition is not only determined to one but is also entirely devoid of contradiction, since it affirms neither being nor non-being. Therefore, the question “What is it?” is not a dialectical interrogation. Thus he says, for the dialectical interrogation must provide, that is, from the proposed dialectical interrogation the one responding must be able to choose whichever part of the contradiction he wishes, which the interrogator must specify—that is, he must propose the question in this way: “Is this animal man or not?” so that the wording of the question clearly offers an option to the one answering. Therefore, a sign that a dialectical question is seeking a response of a proposition or of one part of a contradiction is the setting apart of the question “What is it?” from dialectical questions.
Peri.L5
L. 6 (1.11, 20b31–21a17)Some Predicates Said Divisively of a Subject Can Be Said Conjointly, Others Not
Some Predicates Said Divisively of a Subject Can Be Said Conjointly, Others Not
Peri.L6
Quoniam vero haec quidem praedicantur composita, ut unum omne praedicatum fiat eorum quae extra praedicantur, alia vero non; quae differentia est? De homine enim verum est dicere, et extra animal, et extra bipes; et haec ut unum: et, hominem, et, album; et haec ut unum. Sed non si citharoedus (coriarius) est et bonus, etiam citharoedus (coriarius) bonus.
20b31. Some things predicated separately are such that they unite to form one predicate; others, however, do not. What, then, is the difference? For it is true to say separately of man that he is an animal and that he is biped, and it is also true to say these as one. It is also true to say “man” and “white” separately of him and to say these as one. But if a man is a shoemaker and also good, it is not true to say that he is a good shoemaker.
Peri.L6
Si enim quoniam utrumque, verum, esse oportet et simul utrumque multa inconvenientia erunt. De homine enim verum est et hominem , et album dicere; quare et omne. Rursus si album, et omne. Quare erit homo albus albus; et hoc in in iinitum. Et rursus musicus albus ambulans; et haec eadem frequenter implicita in infinitum. Amplius si Socrates, Socrates est, et homo; et Socrates Socrates homo; et si homo et bipes, erit homo homo bipes.
20b36. For if we hold that whenever each is truly said of a subject, both together must also be true, many absurdities will follow. For example, it is true to say of man that he is man and that he is white; therefore, these two taken together can also be truly said of him; again, if it is true to say that he is white and that he is also the two combined predicates above, he will be white white man; and so to infinity. Or, again, “musical,” “white,” and “walking” may be truly said of man; and these combined many times. Furthermore, if Socrates is Socrates and a man, Socrates is a Socrates man; and if he is man and biped, he is a biped man.
Peri.L6
Quod igitur si quis simpliciter dicat complexiones fieri, plurima inconvenientia contingere manifestum est. Quemadmodum ponendum est nunc dicimus.
It is clear, therefore, that if anyone says these combinations can always be made simply, many absurd things follow. Now, we will state how this must be resolved.
Peri.L6
Eorum igitur quae praedicantur, et de quibus praedicari accidit quaecumque secundum accidens dicuntur, vel de eodem, vel alterum de altero, haec non erunt unum; ut, homo albus est et musicus; sed non est unum album et musicum; accidentia enim sunt utraque eidem. Nec, si album, musicum verum est dicere, tamen non erit musicum album unum aliquid: secundum accidens enim album musicum dicetur; quare non erit album musicum unum aliquid.
21a7. Those things that are predicated—taken in relation to that to which they are joined in predication—which are said accidentally, either of the same subject or one another, will not be one. For example, man is white and musical, but whiteness and being musical are not one, for both are accidental to the same thing. Even if it were true to say that whatever is white is musical, musical and white will not be one thing, for that which is musical is white accidentally; consequently, that which is white will not be musical.
Peri.L6
Quocirca nec citharoedus (coriarius) bonus simpliciter; sed animal bipes: non enim sunt secundum accidens.
21a14. This is the reason “good” and “shoemaker” cannot be combined simply; but “biped” and “animal” can, for these are not accidental.
Peri.L6
Amplius nec quaecumque insunt in alio. Quare neque album frequenter dictum, neque homo homo animal est, vel bipes; insunt enim in homine animal et bipes.
21a16. Furthermore, predicates that are present in one another cannot be combined simply. This is the reason we cannot combine “white” many times, nor is “man” an “animal-man,” or a “biped-man,” for the notion man includes both biped and animal.
Peri.L6
262. Postquam declaravit diversitatem multiplicis enunciationis, intendit determinare de earum consequentiis.
Having explained the diversity of the multiple enunciation, Aristotle now proposes to determine the consequences of this.
Peri.L6
Et circa hoc duo facit, secundum duas dubitationes quas solvit.
He treats this in relation to two questions which he solves.
Peri.L6
Secunda incipit; ibi: verum autem est dicere et cetera.
The second begins at: on the other hand, it is also true (21a18; [273]).
Peri.L6
Circa primum tria facit:
About the first he does three things.
Peri.L6
primo, proponit quaestionem;
first, he proposes the question,
Peri.L6
secundo, ostendit rationabilitatem quaestionis; ibi: si enim quoniam etc.;
second, he shows that the question is a reasonable one, at: for if we hold that whenever each is truly said (20b36; [263]).
Peri.L6
tertio, solvit eam; ibi: eorum igitur et cetera.
third, he solves it, at: those things that are predicated (21a7; [264]).
Peri.L6
Est ergo dubitatio prima: quare ex aliquibus divisim praedicatis de uno sequitur enunciatio, in qua illamet unita praedicantur de eodem, et ex aliquibus non. Unde haec diversitas oritur? Verbi gratia; ex istis, Socrates est animal et est bipes; sequitur, ergo Socrates est animal bipes; et similiter ex istis, Socrates est homo et est albus; sequitur, ergo Socrates est homo albus. Ex illis vero, Socrates est bonus, et est citharoedus; non sequitur, ergo est bonus citharoedus. Unde proponens quaestionem inquit: quoniam vero haec, scilicet praedicta, ita praedicantur composita, idest coniuncta, ut unum sit praedicamentum quae extra praedicantur, idest, ut ex eis extra praedicatis unite fiat praedicatio, alia vero praedicata non sunt talia, quae est inter differentia; unde talis innascitur diversitas? Et subdit exempla iam adducta, et ad propositum applicata: quorum primum continet praedicata ex quibus fit unum per se, scilicet, animal et bipes, genus et differentia; secundum autem praedicata ex quibus fit unum per accidens, scilicet, homo albus; tertium vero praedicata ex quibus neque unum per se neque unum per accidens inter se fieri sequitur; ut, citharoedus et bonus, ut declarabitur.
The first question is this: why is it that from some things predicated divisively of a subject an enunciation follows in which they are predicated of the same subject unitedly, and from others not? What is the reason for this diversity? For example, from “Socrates is an animal and he is biped” follows “Therefore, Socrates is a biped animal.” Similarly, from “Socrates is a man and he is white” follows “Therefore, Socrates is a white man.” But from “Socrates is good and he is a lute player,” the enunciation, “Therefore, he is a good lute player” does not follow. Hence in proposing the question Aristotle says, some things, namely, predicates, are so predicated when combined that there is one predicate from what is predicated separately—that is, from some things that are predicated separately, a united predication is made, but from others this is not so. What is the difference between these? From where does such a diversity arise? He adds the examples which we have already cited and applied to the question. Of these examples, the first contains predicates from which something essentially one is formed, namely, “animal” and “biped,” a genus and difference; the second contains predicates from which something accidentally one is formed, namely, “white man”; the third contains predicates from which neither one essentially nor one accidentally is formed, “lute player” and “good,” as will be explained.
Peri.L6
263. Deinde cum dicit: si enim quoniam etc., declarat veritatem diversitatis positae, ex qua rationabilis redditur quaestio: si namque inter praedicata non esset talis diversitas, irrationabilis esset dubitatio. Ostendit autem hoc ratione ducente ad inconveniens, nugationem scilicet. Et quia nugatio duobus modis committitur, scilicet explicite et implicite;
When he says, for if we hold that whenever each (20b36), he shows that there truly is such a diversity among predicates and in so doing renders the question reasonable, for if there were not such a diversity among predicates the question would be pointless. He shows this by reasoning leading to an absurdity, that is, to something nugatory. Now, something nugatory is effected in two ways, explicitly and implicitly.
Peri.L6
ideo primo deducit ad nugationem explicitam,
Therefore, he first makes a deduction to the explicitly nugatory;
Peri.L6
secundo ad implicitam; ibi: amplius, si Socrates et cetera.
second, to the implicitly, at: furthermore, if Socrates is Socrates and a man, Socrates is a Socrates man (20b36).
Peri.L6
Ait ergo quod si nulla est inter quaecumque praedicata differentia, sed de quolibet indifferenter censetur quod quia alterutrum separatum dicitur, quod utrumque coniunctim dicatur, multa inconvenientia sequentur. De aliquo enim homine, puta Socrate, verum est separatim dicere quod, homo est, et albus est; quare et omne, idest et coniunctim dicetur, Socrates est homo albus. Rursus et de eodem Socrate potest dici separatim quod, est homo albus, et quod, est albus; quare et omne, idest, igitur coniunctim dicetur, Socrates est homo albus albus: ubi manifesta est nugatio. Rursus si de eodem Socrate iterum dicas separatim quod, est homo albus albus, verum dices et congrue quod est albus, et secundum hoc, si iterum hoc repetes separatim, a veritate simili non discedes, et sic in infinitum sequetur, Socrates est homo albus, albus, albus in infinitum.
If, he says, there is no difference between predicates, and it is supposed of any of them indifferently that because both are said separately both may be said conjointly, many absurdities will follow. For it is true of some man (say Socrates) to say separately that he is a man and he is white, and therefore he is both together—that is, we may also say conjointly, “Socrates is a white man.” Again, of the same Socrates we can say separately that he is a white man and that he is white, and both together—that is, conjointly, “Socrates is a white white man.” Here the nugatory expression is evident. Further, if of the same Socrates that you again say separately is a “white white man” it will be true and consistent to say that he is white, and following this, if you will not deviate from a similar truth by again repeating this separately (and this will follow to infinity), then Socrates is a “white white white man” to infinity.
Peri.L6
Simile quod ostenditur in alio exemplo. Si quis de Socrate dicat quod, est musicus, albus, ambulans, cum possit et separatim dicere quod, est musicus, et quod, est albus, et quod, est ambulans; sequetur, Socrates est musicus, albus, ambulans, musicus, albus, ambulans. Et quia pluries separatim, in eodem tamen tempore, enunciari potest, procedit nugatio sine fine.
The same thing can be shown by another example. If someone says of Socrates that he is “musical,” “white,” and “walking,” since it is also possible to say separately that he is musical, and that he is white, and that he is walking, it will follow that “Socrates is musical, white, walking, musical, white, walking.” And since these can be enunciated many times separately, yet at the same time, the nugatory statement proceeds without end.
Peri.L6
Deinde deducit ad implicitam nugationem, dicens, cum de Socrate vere dici possit separatim quod, est homo, et quod, est bipes, si coniunctim inferre licet, sequetur quod, Socrates sit homo bipes. Ubi est implicita nugatio. Bipes enim circumloquens differentiam hominis actu et intellectu clauditur in hominis ratione. Unde ponendo loco hominis suam rationem (quod fieri licet, ut docet Aristoteles II topicorum), apparebit manifeste nugatio. Dicetur enim: Socrates est homo, idest, animal bipes, bipes.
Next he makes a deduction to the implicitly nugatory. Since it can be truly said of Socrates separately that he is man and that he is biped, it will follow that Socrates is a biped man, if it is licit to infer conjointly. This is implicitly nugatory because the “biped,” which indirectly expresses the difference of man in act and in understanding, is included in the notion of man. Hence, if we posit the definition of man in place of “man” (which it is licit to do, as Aristotle teaches in Topics 2.2 [110a5]) the nugatory character of the enunciation will be evident, for when we say “Socrates is a biped man,” we are saying “Socrates is a biped biped animal.”
Peri.L6
Quoniam ergo plurima inconvenientia sequuntur si quis ponat complexiones, idest, adunationes praedicatorum fieri simpliciter, idest, absque diversitate aliqua, manifestum est ex dictis; quomodo autem faciendum est, nunc, idest, in sequentibus dicemus. Et nota quod iste textus non habetur uniformiter apud omnes quoad verba, sed quia sententia non discrepat, legat quicunque ut vult.
From what has been said it is evident that many absurdities follow if anyone proposes that combinations (or unions of predicates), be made simply, that is, without any distinction. Now, that is, in what follows, we will state how this must be settled. This particular text is not uniformly worded in the manuscripts, but since no discrepancy of thought is involved one may read it as he wishes.
Peri.L6
264. Deinde cum dicit: eorum igitur etc., solvit propositam quaestionem.
When he says, those things that are predicated (21a7), he solves the proposed question.
Peri.L6
Et circa hoc duo facit:
About this he does two things.
Peri.L6
primo, respondet instantiis in ipsa propositione quaestionis adductis;
First, he makes an answer with respect to the instances cited in proposing the question;
Peri.L6
secundo, satisfacit instantiis in probatione positis; ibi: amplius nec quaecumque et cetera.
second, he solves the problem as related to the instances posited in his proof, at: furthermore, predicates that are present (21a16; [272]).
Peri.L6
Circa primum duo facit:
About the first he does two things:
Peri.L6
primo namque, declarat veritatem;
first, he states the true position;
Peri.L6
secundo, applicat ad propositas instantias; ibi: quocirca et cetera.
second, he applies it to the instances, at: this is the reason “good” and “shoemaker” (21a14; [268]).
Peri.L6
Determinat ergo dubitationem tali distinctione. Praedicatorum sive subiectorum plurium duo sunt genera: quaedam sunt per accidens, quaedam per se. Si per accidens, hoc dupliciter contingit, vel quia ambo dicuntur per accidens de uno tertio, vel quia alterum de altero mutuo per accidens praedicatur. Quando illa plura divisim praedicata sunt per accidens quovis modo, ex eis non sequitur coniunctim praedicatum; quando autem sunt per se, tum ex eis sequitur coniuncte praedicatum.
He settles the question with this distinction: there are two kinds of multiple predicates and subjects. Some are accidental, some per se. If they are accidental, this occurs in two ways: either because both are said accidentally of a third thing or because they are predicated of each other accidentally. Now when the many predicated divisively are in any way accidental, a conjoined predicate does not follow from them; but when they are per se, a conjoined predicate does follow from them.
Peri.L6
Unde continuando se ad praecedentia ait: eorum igitur quae praedicantur, et de quibus praedicantur, idest subiectorum, quaecumque dicuntur secundum accidens (et per hoc innuit oppositum membrum, scilicet per se), vel de eodem, idest accidentaliter concurrunt ad unius tertii denominationem, vel alterutrum de altero, idest accidentaliter mutuo se denominant (et per hoc ponit membra duplicis divisionis), haec, scilicet plura per accidens, non erunt unum, idest non inferent praedicationem coniunctam.
In answering the question, therefore, Aristotle connects what he is saying with what has gone before: of those things that are predicated and those of which they are predicated, namely, subjects, whichever are said accidentally (by which he intimates the opposite member, namely, per se), either of the same subject, that is, they unite accidentally for the denomination of one third thing, or of one another, that is, they denominate each other accidentally (and by this he posits the members of a two-fold division), these, namely, these many accidentally, will not be one, that is, do not produce a conjoined predication.
Peri.L6
265. Et explanat utrumque horum exemplariter.
He explains both of these by examples.
Peri.L6
Et primo, primum, quando scilicet illa plura per accidens dicuntur de tertio, dicens: ut si homo albus est et musicus divisim. Sed non est idem, idest non sequitur adunatim, ergo homo est musicus albus. Utraque enim sunt accidentia eidem tertio.
First, he explains the first (21a7)—when the many are said accidentally of a third—with the example of how man is white and musical divisively. But they are not the same, that is, it does not follow unitedly that man is musical white, for both are accidental to the same third thing.
Peri.L6
Deinde explanat secundum, quando solum illa plura per accidens de se mutuo praedicantur, subdens: nec si album musicum verum est dicere, idest, et etiamsi de se invicem ista praedicantur per accidens ratione subiecti in quo uniuntur, ut dicatur, homo est albus, et est musicus, et album est musicum, non tamen sequitur quod album musicum unite praedicetur, dicendo, ergo homo est albus musicus. Et causam assignat, quia album dicitur de musico per accidens, et e converso.
Then he explains the second member by an example. In it, the many are predicated only of one another. Even if it were true to say white is musical—that is, even if these are predicated accidentally of each other by reason of the subject in which they are united, so that we may say man is white and he is musical, and white is musical—it still does not follow that musical white is predicated as a unity when we say, therefore, man is musical white. He gives as the cause of this that white is said of musical accidentally and conversely.
Peri.L6
266. Notandum est hic quod cum duo membra per accidens enumerasset, unico tamen exemplo utrumque membrum explanavit, ut insinuaret quod distinctio illa non erat in diversa praedicata per accidens, sed in eadem diversimode comparata; album enim et musicum, comparata ad hominem, sub primo cadunt membro; comparata autem inter se, sub secundo. Diversitatem ergo comparationis pluralitate membrorum, identitatem autem praedicatorum unitate exempli astruxit.
It must be noted here that although he has enumerated two accidental members, he explains both members by this single example so as to imply that the distinction is not one of different accidental predicates, but of the same predicates compared in different ways. White and musical compared to “man” fall under the first member, but compared with each other, under the second. Hence he has provided diversity of comparison by the plurality of the members, but identity of predicates by the unity of the example.
Peri.L6
267. Advertendum est ulterius, ad evidentiam divisionis factae in littera, quod, secundum accidens, potest dupliciter accipi.
To make this division evident, it must also be noted that “accidentally” can be taken in two ways.
Peri.L6
Uno modo, ut distinguitur contra perseitatem posterioristicam, et sic non sumitur hic: quoniam cum dicitur plura praedicata secundum accidens, aut ly secundum accidens determinaret coniunctionem inter se, et sic manifeste esset falsa regula; quoniam inter prima praedicata, animal bipes, seu, animal rationale, est praedicatio secundum accidens hoc modo (differentia enim in nullo modo perseitatis praedicatur de genere, et tamen Aristoteles in textu dicit ea non esse praedicata per accidens, et asserit quod est optima illatio, est animal et bipes, ergo est animal bipes); aut determinaret coniunctionem illarum ad subiectum, et sic etiam inveniretur falsitas in regula: bene namque dicitur, paries est coloratus, et est visibilis, et tamen coloratum visibile non per se inest parieti.
In one way, it may be taken as it is distinguished from “posterioristic essentiality.” This is not the way it is taken here, for “many predicates accidentally” would then mean that the accidentally determines a conjunction between predicates, and thus the rule would clearly be false, for the first predicates he gave as examples are predicated accidentally in this way, namely, “biped animal,” or “rational animal.” For a difference is not predicated of a genus in any mode of essentiality, and yet Aristotle says in the text that these are not predicated accidentally, and has asserted that he is an animal and biped, therefore he is a biped animal is a good inference. Or it would mean that the “accidentally” determines a conjunction of the predicates with the subject, and thus also the rule would be false, for it is valid to say, “The wall is colored and it is visible,” yet “visible colored” is not per se in the wall.
Peri.L6
Alio modo, accipitur ly secundum accidens, ut distinguitur contra hoc quod dico, ratione sui, seu, non propter aliud, et sic idem sonat, quod, per aliud: et hoc modo accipitur hic. Quaecunque enim sunt talis naturae quod non ratione sui iunguntur, sed propter aliud, ab illatione coniuncta deficere necesse est, ex eo quod coniuncta illatio unum alteri substernit, et ratione sui ea adunata denotat ut potentiam et actum. Est ergo sensus divisionis, quod praedicatorum plurium, quaedam sunt per accidens, quaedam per se, idest, quaedam adunantur inter se ratione sui, quaedam propter aliud. Ea quae per se uniuntur inferunt coniunctum, ea autem quae propter aliud, nequaquam.
Accidentally taken in the second way is distinguished from what I call “on its own account,” that is, not because of something else. “Accidentally” then means “through another.” This is the way it is taken here, for whatever things are of such a nature that they are joined because of something else, and not on their own account, do not admit of conjoined inference, because a conjoined inference subjects one to the other, and denotes the things united on their own account as potency and act. Therefore, the sense of the division is this: of many predicates, some are accidental, and some are per se—that is, some are united among themselves on their own account, some on account of another. Those that are per se united infer conjointly; those that are united on account of another do not infer conjointly in any way.
Peri.L6
268. Deinde cum dicit: quocirca nec citharoedus etc., applicat declaratam veritatem ad partes quaestionis.
When he says, this is the reason “good” and “shoemaker” cannot be combined simply (21a14), he applies the truth he has stated to the parts of the question.
Peri.L6
Et primo, ad secundam partem, quia scilicet non sequitur: est bonus et est citharoedus; ergo est bonus citharoedus, dicens: quocirca nec citharoedus bonus etc.;
He applies it first to the second part, that is, why this does not follow: “He is good and he is a shoemaker, therefore he is a good shoemaker,” at: this is the reason “good” and “shoemaker.”
Peri.L6
secundo, ad aliam partem quaestionis, quare sequebatur: est animal et est bipes; ergo est animal bipes: et ait: sed animal bipes et cetera. Et subiungit huius ultimi dicti causam, quia, animal bipes, non sunt praedicata secundum accidens coniuncta inter se aut in tertio, sed per se.
Second, he applies it to the other part of the question, that is, why this follows: “He is an animal and he is biped, therefore he is a biped animal,” at: but “biped” and “animal” can. He adds the reason in the case of the latter: “biped” and “animal” are not predicates accidentally conjoined among themselves, nor in a third thing, but per se.
Peri.L6
Et per hoc explanavit alterum membrum primae divisionis, quod adhuc positum non fuerat explicite. Adverte quod Aristoteles, eamdem tenens sententiam de citharoedo et bono et musico et albo, conclusit quod album et musicum non inferunt coniunctum praedicatum; ideo nec citharoedus et bonus inferunt citharoedus bonus simpliciter, idest coniuncte.
This also explains the other member of the first division which has not yet been explicitly posited. Notice that he maintains the same judgment is to be made about lute player and good, and musical and white. He has concluded that “white” and “musical” do not infer a conjoined predicate; hence neither do “lute player” and “good” infer “good lute player” simply, that is, conjointly.
Peri.L6
Est autem ratio dicti, quia licet musica et albedo dissimiles sint bonitati et arti citharisticae in hoc, quod bonitas nata est denominare et subiectum tertium, puta hominem et ipsam artem citharisticam (propter quod falsitas manifeste cernitur, quando dicitur: est bonus et citharoedus; ergo bonus citharoedus), musica vero et albedo subiectum tertium natae sunt denominare tantum, et non se invicem (propter quod latentior est casus cum proceditur: est albus et est musicus; ergo est musicus albus), licet, inquam, in hoc sint dissimiles, et propter istam dissimilitudinem processus Aristotelis minus sufficiens videatur;
There is a reason for saying this. For although there is a difference between musical and white, and goodness and the art of lute-playing, they are also similar. Let us consider their difference first. Goodness is of such a nature that it denominates both a third subject (namely, man) and the art of lute-playing. This is the reason the falsity is clearly discernible when we say “He is good and a lute player, therefore he is a good lute player.” Musical and whiteness, on the other hand, are of such a nature that they denominate only a third subject, and not each other, and hence the error is less obvious in “He is white and he is musical, therefore he is musical white.” Now it is this difference that makes Aristotle’s process of reasoning appear somewhat inconclusive.
Peri.L6
attamen similes sunt in hoc quod, si servetur identitas omnimoda praedicatorum quam servari oportet, si illamet divisa debent inferri coniunctim, sicut musica non denominat albedinem, neque contra, ita nec bonitas, de qua fit sermo, cum dicitur, homo est bonus, denominat artem citharisticam, neque e converso. Cum enim bonum sit aequivocum, licet a consilio, alia ratione dicitur de perfectione citharoedi, et alia de perfectione hominis. Quando namque dicimus, Socrates est bonus, intelligimus bonitatem moralem, quae est hominis bonitas simpliciter (analogum siquidem simpliciter positum sumitur pro potiori); cum autem infertur, citharoedus bonus, non bonitatem moris sed artis praedicas: unde terminorum identitas non salvatur; sufficienter igitur et subtiliter Aristoteles eamdem de utrisque protulit sententiam, quia eadem est haec, et ibi ratio et cetera.
However, they are similar. For if identity of predicates is kept in every way that is required for the same things divided to be inferred conjointly, then, just as “musical” does not denominate “whiteness,” nor the contrary, so neither does “goodness” (of which we are speaking when we say “man is good”) denominate the art of lute-playing, nor conversely. For “good” is equivocal, even though by choice, and is therefore said of the perfection of the lute player by means of one notion and of the perfection of man by means of another. For example, when we say, “Socrates is good” we understand moral goodness, which is the goodness of man absolutely (for the analogous term posited simply stands for what is mainly so); but when “good lute player” is inferred, it is not the goodness of morality that is predicated, but the goodness of art. Thus the identity of the terms is not saved. Therefore, Aristotle has adequately and subtly expressed the same judgment about both pairs (“white” and “musical,” and “good” and “lute player”), for the reason here is the same as there.
Peri.L6
269. Nec praetereundum est quod, cum tres consequentias adduxit quaestionem proponendo, scilicet; est animal et bipes; ergo est animal bipes: et, est homo et albus; ergo est homo albus: et, est citharoedus et bonus; ergo est homo albus: et, est citharoedus et bonus; ergo est bonus citharoedus; et duas primas posuerat esse bonas, tertiam vero non; huius diversitatis causam inquirere volens, cur solvendo quaestionem nullo modo meminerit secundae consequentiae, sed tantum primae et tertiae. Indiscussum namque reliquit an illa consequentia sit bona an mala.
There is another point that must be mentioned. Aristotle draws three consequences in proposing the question: “He is an animal and biped, therefore he is a biped animal”; “He is a man and white, therefore he is a white man”; and “He is a lute player and good, therefore he is a good lute player.” Then he states that the first two consequences are good, the third not. His intention was to inquire into the cause of this diversity, but in solving the question he mentions only the first and third consequences, leaving the goodness or badness of the second consequence undiscussed. Why is this?
Peri.L6
Et ad hoc videtur mihi dicendum quod ex his paucis verbis etiam illius consequentiae naturam insinuavit. Profundioris enim sensus textus capax apparet cum dixit quod, non sunt unum album et musicum etc., ut scilicet non tantum indicet quod expositum est, sed etiam eius causam, ex qua natura secundae consequentiae elucescit. Causa namque quare album et musicum non inferunt coniunctam praedicationem est, quia in praedicatione coniuncta oportet alteram partem alteri supponi, ut potentiam actui, ad hoc ut ex eis fiat aliquo modo unum, et altera a reliqua denominetur (hoc enim vis coniunctae praedicationis requirit, ut supra diximus de partibus definitionis); album autem et musicum secundum se non faciunt unum per se, ut patet, neque unum per accidens. Licet enim ipsa ut adunantur in subiecto uno sint unum subiecto per accidens, tamen ipsamet quae adunantur in uno, tertio subiecto, non faciunt inter se unum per accidens:
I would say in answer to this that in these few words he has also implied the nature of the second consequence, for there is a more profound meaning to the statement in the text that whiteness and being musical is not one (21a7). It is a meaning that not only indicates what has already been explained but also its cause, and from this the nature of the second consequence is apparent. The reason “white” and “musical” do not infer a conjoined predication is that in conjoined predication one part must be subjected to the other as potency to act such that in some way one thing is formed from them and one is denominated from the other (for the force of the conjoined predication requires this, as we have said above concerning the parts of the definition). “White” and “musical,” however, do not in themselves form one thing per se, as is evident, nor do they form one thing accidentally. For while it is true that as united in a subject they are one in subject accidentally, nevertheless things that are united in one third subject do not form one thing accidentally among themselves:
Peri.L6
tum quia neutrum informat alterum (quod requiritur ad unitatem per accidens aliquorum inter se, licet non in tertio);
first, because neither informs the other (which is required for accidental unity of things among themselves, although not in a third thing);
Peri.L6
tum quia non considerata subiecti unitate, quae est extra eorum rationes, nulla remanet inter ea unitatis causa.
second, because, considered apart from the unity of a subject, which is outside of their notions, there is no cause of unity between them.
Peri.L6
Dicens ergo quod album et musicum non sunt unum, scilicet inter se, aliquo modo, causam expressit quare coniunctim non infertur ex eis praedicatum. Et quia oppositorum eadem est disciplina, insinuavit per illamet verba bonitatem illius consequentiae. Ex eo enim quod homo et albus se habent sicut potentia et actus (et ita albedo informet, denominet atque unum faciat cum homine ratione sui), sequitur quod ex divisis potest inferri coniuncta praedicatio; ut dicatur: est homo et albus; ergo est homo albus. Sicut per oppositum dicebatur quod ideo musicum et album non inferunt coniunctum praedicatum quia neutrum alterum informabat.
Therefore, when Aristotle says that whiteness and being musical are not one (namely, among themselves), in some measure he expresses the reason why a predicate is not conjointly inferred from them. And since the same discipline extends to opposites, the goodness of the second consequence is implied by these words. That is, man and white are related as potency and act (and so whiteness informs, denominates, and forms one thing with “man” on its own account). Therefore, from these taken divisively a conjoined predication can be inferred, namely, “He is man and white, therefore be is a white man,” just as, in the opposite case, it was said that “musical” and “white” do not infer a conjoined predicate because neither informs the other
Peri.L6
270. Nec obstat quod album faciat unum per accidens cum homine: non enim dictum est quod unitas per accidens aliquorum impedit ex diversis inferre coniunctum, sed quod unitas per accidens aliquorum ratione tertii tantum est illa quae impedit. Talia enim quae non sunt unum per accidens nisi ratione tertii, inter se nullam habent unitatem; et propterea non potest inferri coniunctum, ut dictum est, quod unitatem importat. Illa vero quae sunt unum per accidens ratione sui, seu inter se, ut, homo albus, cum coniuncta accipiuntur, unitate necessaria non carent, quia inter se unitatem habent. Notanter autem apposui ly tantum: quoniam si aliqua duo sunt unum per accidens, ratione tertii subiecti scilicet, sed non tantum ex hoc habent unitatem, sed etiam ratione sui, ex hoc quod alterum reliquum informat, ex istis divisis non prohibetur inferri coniunctum. Verbi gratia, optime dicitur: est quantum et est coloratum; ergo est quantum coloratum: quia color informat quantitatem.
There is no opposition between the position just stated and the fact that white forms an accidental unity with man. For we did not say that accidental unity of certain things impedes inferring a conjunction from divided things, but that accidental unity of certain things only by reason of a third thing is the one that impedes. Things that are one accidentally only by reason of a third thing have no unity among themselves; and for this reason a conjunction, which implies unity, cannot be inferred, as we have said. But things that are one accidentally on their own account (that is, among themselves)—as, for example, white man—have the necessary unity when taken conjointly because they have unity among themselves. Notice that I have added only. The reason is that if any two are one accidentally (that is, by reason of a third subject), and they not only have unity from this but also on their own account (because one informs the other), then from these taken divisively a conjoined inference can be made. For example, we can infer, “It is a quantity and it is colored, therefore it is a colored quantity,” because color informs quantity.
Peri.L6
271. Potes autem credere quod secunda illa consequentia, quam non explicite confirmavit Aristoteles respondendo, sit bona et ex eo quod ipse proponendo quaestionem asseruit bonam, et ex eo quod nulla instantia reperitur. Insinuavit autem et Aristoteles quod sola talis unitas impedit illationem coniunctam, quando dixit quaecumque secundum accidens dicuntur vel de eodem vel alterutrum de altero. Cum enim dixit, secundum accidens de eodem, unitatem eorum ex sola adunatione in tertio posuit (sola enim haec per accidens praedicantur de eodem, ut dictum est); cum autem addidit, vel alterutrum de altero, mutuam accidentalitatem ponens, ex nulla parte inter se unitatem reliquit. Utraque ergo per accidens adducta praedicata, in tertio scilicet vel alterutrum, quae impediant illationem coniunctam, nonnisi in tertio unitatem habent.
You can hold as true that this second consequence is good even though Aristotle has not explicitly confirmed it by returning to it, both from the fact that in proposing the question he has claimed it as good and also because there is no instance opposed to it. Moreover, Aristotle has implied that it is only such unity that impedes the conjoined inference where he says: which are said accidentally, either of the same subject or of one another (21a7). By accidentally of the same subject, he posits their unity to be only from union in a third thing (for only these are predicated accidentally of the same subject, as was said). When he adds or of one another—positing mutual accidentality—no unity at all is left between them. Therefore, both kinds of accidental predicates (namely, in a third thing or in one another) that impede a conjoined inference have unity only in a third thing.
Peri.L6
272. Deinde cum dicit: amplius nec etc., satisfacit instantiis in probatione adductis, et in illis in quibus explicita committebatur nugatio, et in illis in quibus implicita; et ait quod non solum inferre ex divisis coniunctum non licet quando praedicata illa sunt per accidens, sed nec etiam quaecunque insunt in alio: idest, sed nec hoc licet quando praedicata includunt se, ita quod unum includatur in significato formali alterius intrinsece, sive explicite, ut album in albo, sive implicite, ut animal et bipes in homine. Quare neque album frequenter dictum divisim infert coniunctum, neque homo divisim ab animali vel bipede enunciatum, animal bipes, coniunctum cum homine infert; ut dicatur, ergo Socrates est homo bipes, vel animal homo. Insunt enim in hominis ratione, animal et bipes actu et intellectu, licet implicite.
Then when he says, furthermore, predicates that are present (21a16), he gives the solution for the instances (both the explicitly nugatory and the implicitly nugatory) cited in the proof. It is not only illicit, he says, to infer a union from divided predicates when these are accidental, but it is illicit when the predicates are present in one another. That is, it is illicit to infer a conjoined predicate from divided predicates when the predicates include one another in such a way that one is included in the formal signification of another intrinsically, or explicitly (as “white” in “white”), or implicitly (as “animal” and “biped” in “man”). Therefore, “white” said repeatedly and divisively does not infer a conjoined predication, nor does “man” divisively enunciated from “animal” or “biped” infer “biped” or “animal” conjoined with man, such that we could say, “Therefore, Socrates is a biped-man” or “animal-man.” For “animal” and “biped” are included in the notion of man in act and in understanding, although implicitly.
Peri.L6
Stat ergo solutio quaestionis in hoc, quod unitas plurium per accidens in tertio tantum et nugatio, impediunt ex divisis inferri coniunctum; et consequenter, ubi neutrum horum invenitur, ex divisis licebit inferre coniunctum. Et hoc intellige quando divisae sunt simul verae de eodem et cetera.
The solution of the question, then, is this: the inferring of a conjunction from divided predicates is impeded when there is unity of the many accidentally, only in a third thing, and with a nugatory result. Consequently, where neither of these is found, it will be licit to infer a conjunction from divided predicates. It is to be understood that this applies when the divided predicates are at once true of the same subject.
Peri.L6
L. 7 (1.11, 21a18–21a33)Whether From an Enunciation Having Many Conjoined Predicates It Is Licit to Infer an Enunciation That Contains the Same Predicates Divisively
Whether From an Enunciation Having Many Conjoined Predicates It Is Licit to Infer an Enunciation That Contains the Same Predicates Divisively
Peri.L7
Verum autem est dicere de aliquo et simpliciter; ut aliquem hominem hominem, aut aliquem album hominem, hohominem album: non autem semper.
21a18. On the other hand, it is also true to say predicates of something singly; for example, it is true to say that some man is a man, or that some white man is white. However, this is not always the case.
Peri.L7
Sed quando in adiecto aliquid quidem oppositorum insit, quod consequitur contradictio, non verum sed falsum est; ut, hominem mortuum, hominem dicere: quando autem non insit, verum est.
21a21. When something opposed is present in the adjunct, from which a contradiction follows, it will not be true to predicate them singly, but false—for instance, to say that a dead man is a man. When something opposed is not present in the adjunct, however, it is true to predicate them singly.
Peri.L7
Aut quando insit quidem, semper non verum est: quando vero non insit, non semper verum est; ut, Homerus est aliquid, ut poeta: utrum igitur est, an ergo etiam est; non?
21a24. Or, rather, when something opposed is present in it, it is never true; but when something opposed is not present, it is not always true. For example, Homer is something, say, a poet. Is it therefore true to say also that Homer is, or not?
Peri.L7
Secundum accidens enim praedicatur, est, de Homero; (quoniam est enim poeta), sed non secundum se praedicatur de Homero ipsum est.
21a26. The “is” here is predicated accidentally of Homer, for the “is” is predicated of him with regard to the fact that he is a poet, not in itself.
Peri.L7
Quare in quantiscumque praedicationibus neque contrarietas, [aliqua aut nulla oppositio] inest, si definitiones pro nominibus dicantur, et secundum se praedicantur et non secundum accidens, in his aliquid et simpliciter verum erit dicere.
21a29. Therefore, in whatever predications no contrariety is present when definitions are put in place of the names, and wherein predicates are predicated in itself and not accidentally, it will also be true to predicate each one singly.
Peri.L7
Quod autem non est, quoniam opinabile est, non est verum dicere esse aliquid: opinio enim eius non est, quoniam est, sed quoniam non est.
21a32. In the case of non-being, however, it is not true to say that because it is a matter of opinion it is something; for the opinion of it is not that it is, but that it is not.
Peri.L7
273. Postquam expedita est prima dubitatio, tractat secundam dubitationem.
Aristotle now takes up the second question in relation to multiple enunciations.
Peri.L7
Et circa hoc tria facit:
About this he does three things.
Peri.L7
primo, movet ipsam quaestionem;
First, he presents it;
Peri.L7
secundo, solvit eam; ibi: sed quando in adiecto etc.;
second, he solves it, at: when something opposed is present in the adjunct (21a21; [274]);
Peri.L7
tertio, ex hoc excludit quemdam errorem; ibi: quod autem non est et cetera.
third, he excludes an error, at: in the case of non-being, however (21a32; [289]).
Peri.L7
Est ergo quaestio: an ex enunciatione habente praedicatum coniunctum, liceat inferre enunciationes dividentes illud coniunctum; et est quaestio contraria superiori. Ibi enim quaesitum est an ex divisis inferatur coniunctum; hic autem quaeritur an ex coniuncto sequantur divisa. Unde movendo quaestionem dicit: verum autem aliquando est dicere de aliquo et simpliciter, idest divisim, quod scilicet prius dicebatur coniunctim, ut quemdam hominem album esse hominem, aut quoddam album hominem album esse, idest ut ex ista, Socrates est homo albus, sequitur divisim, ergo Socrates est homo, ergo Socrates est albus. Non autem semper, idest aliquando autem ex coniuncto non inferri potest divisim; non enim sequitur, Socrates est bonus citharoedus, ergo est bonus. Unde haec est differentia, quod quandoque licet et quandoque non. Et adverte quod notanter adduxit exemplum de homine albo, inferendo utramque partem divisim, ut insinuaret quod intentio quaestionis est investigare quando ex coniuncto potest utraque pars divisim inferri, et non quando altera tantum.
This is the question: Is it licit to infer from an enunciation having a conjoined predication, enunciations dividing that conjunction? This question is the contrary of the first question. The first asked whether a conjoined predicate could be inferred from divided predicates; the present one asks whether divided predicates follow from conjoined predicates. When he presents the question he says, on the other hand, it is also true to say predicates of something singly, that is, what was previously said conjointly may be said divisively, for example, that some white man is a man, or that some white man is white. That is, from “Socrates is a white man,” follows divisively, “Therefore, Socrates is a man,” and “Therefore, Socrates is white.” However, this is not always the case, that is, sometimes it is not possible to infer divisively from conjoined predicates, for this does not follow: “Socrates is a good lute player; therefore, he is good.” Hence, sometimes it is licit, sometimes not. Note that in inferring each part divisively he takes as an example “white man.” This is significant, for by it he means to imply that his intention is to investigate when each part can be inferred divisively from a conjoined predicate, and not when only one of the two can be inferred.
Peri.L7
274. Deinde cum dicit: sed quando in adiecto etc., solvit quaestionem.
When he says, when something opposed is present in the adjunct (21a21), he solves the question.
Peri.L7
Et duo facit:
And he does two things.
Peri.L7
primo, respondet parti negativae quaestionis, quando scilicet non licet;
First, he responds to the negative part of the question, that is, when it is not licit;
Peri.L7
secundo, ibi: quare in quantiscumque etc., respondet parti affirmativae, quando scilicet licet.
second, to the affirmative part, that is, when it is licit, at: therefore, in whatever predications (21a29; [280]).
Peri.L7
Circa primum considerandum quod quia dupliciter contingit fieri praedicatum coniunctum, uno modo ex oppositis, alio modo ex non oppositis, ideo duo facit:
It should be noted, in relation to the negative part of the question, that a conjoined predicate may be formed in two ways: from opposites and from non-opposites.
Peri.L7
primo, ostendit quod numquam ex praedicato coniuncto ex oppositis possunt inferri eius partes divisim;
Therefore, he shows first that the parts in a conjoined predicate of opposites can never be inferred divisively.
Peri.L7
secundo, quod nec hoc licet universaliter in praedicato coniuncto ex non oppositis, ibi: vel etiam quando et cetera.
Second, he shows that this is not licit universally in a conjoined predicate of non-opposites, at: or, rather, when something opposed (21a24; [278]).
Peri.L7
Ait ergo quod quando in termino adiecto inest aliquid de numero oppositorum, ad quae sequitur contradictio inter ipsos terminos, non verum est, scilicet inferre divisim, sed falsum. Verbi gratia cum dicitur, Caesar est homo mortuus, non sequitur, ergo est homo: quia ly mortuus, adiacens homini, oppositionem habet ad hominem, quam sequitur contradictio inter hominem et mortuum: si enim est homo, non est mortuus, quia non est corpus inanimatum; et si est mortuus, non est homo, quia mortuum est corpus inanimatum. Quando autem non inest, scilicet talis oppositio, verum est, scilicet inferre divisim. Ratio autem quare, quando est oppositio in adiecto, non sequitur illatio divisa est, quia alter terminus ex adiecti oppositione corrumpitur in ipsa enunciatione coniuncta. Corruptum autem seipsum absque corruptione non infert, quod illatio divisa sonaret.
Aristotle says, then, that when something that is an opposite is contained in the adjacent term, which results in a contradiction between the terms themselves, it is not true, but false, to infer divisively. For example, when we say, “Caesar is a dead man,” it does not follow, “Therefore, he is a man,” because the contradiction between “man” and “dead” which results from adding the “dead” to “man” is opposed to man. For if he is a man, he is not dead, because he is not an inanimate body; and if he is dead, he is not a man, because as dead he is an inanimate body. When something opposed is not present, namely, when there is no such opposition, it is true, that is, it is true to infer divisively. The reason a divided inference does not follow when there is opposition in the added term is that in a conjoined enunciation the other term is destroyed by the opposition of the added term. But that which has been destroyed is not inferred apart from the destruction, which is what the divided inference would signify.
Peri.L7
275. Dubitatur hic primo circa id quod supponitur, quomodo possit vere dici, Caesar est homo mortuus, cum enunciatio non possit esse vera, in qua duo contradictoria simul de aliquo praedicantur. Hoc enim est primum principium. Homo autem et mortuus, ut in littera dicitur, contradictoriam oppositionem includunt, quia in homine includitur vita, in mortuo non vita.
Two questions arise at this point. The first concerns something assumed here: how can it ever be true to make such a statement as “Caesar is a dead man,” since an enunciation cannot be true in which two contradictories are predicated at the same time of something (for this is a first principle)? But “man” and “dead,” as is said in the text, include contradictory opposition, for in man is included life, and in dead, non-life.
Peri.L7
Dubitatur secundo circa ipsam consequentiam, quam reprobat Aristoteles: videtur enim optima. Cum enim ex enunciatione praedicante duo contradictoria possit utrumque inferri (quia aequivalet copulativae), aut neutrum (quia destruit seipsam), et enunciatio supradicta terminos oppositos contradictorie praedicet, videtur sequi utraque pars, quia falsum est neutram sequi.
The second question concerns the consequent that Aristotle rejects, which appears to be good. The enunciation given as an example predicates terms that are opposed contradictorily. But from an enunciation predicating two contradictory terms, either both can be inferred (because it is equivalent to a copulative enunciation), or neither (because it destroys itself); therefore, both parts seem to follow, since it is false that neither follows.
Peri.L7
276. Ad hoc simul dicitur quod aliud est loqui de duobus terminis secundum se, et aliud de eis ut unum stat sub determinatione alterius.
These two questions can be answered simultaneously. It is one thing to speak of two terms in themselves, and another to speak of them as one stands under the determination of another.
Peri.L7
Primo namque modo, homo et mortuus, contradictionem inter se habent, et impossibile est quod simul in eodem inveniantur.
Taken in the first way, “man” and “dead” have a contradiction between them and it is impossible that they be found in the same thing at the same time.
Peri.L7
Secundo autem modo, homo et mortuus, non opponuntur, quia homo transmutatus iam per determinationem corruptivam importatam in ly mortuus, non stat pro suo significato secundum se, sed secundum exigentiam termini additi, a quo suum significatum distractum est.
In the second way, however, “man” and “dead” are not opposed, since “man,” changed by the destructive element introduced by “dead,” no longer stands for what it signifies as such, but as determined by the term added, by which what is signified is removed.
Peri.L7
Ad utrumque autem insinuandum Aristoteles duo dixit, et quod habent oppositionem quam sequitur contradictio, attendens significata eorum secundum se, et quod etiam ex eis formatur una vera enunciatio cum dicitur, Socrates est homo mortuus, attendens coniunctionem eorum alterius corruptivam. Unde patet quid dicendum sit ad dubitationes. Ad utramque siquidem dicitur, quod non enunciantur duo contradictoria simul de eodem, sed terminus ut stat sub distractione, seu transmutatione alterius, cui secundum se esset contradictorius.
Aristotle, in order to imply both, says two things: that they have the opposition upon which contradiction follows if you regard what they signify in themselves; and that one true enunciation is formed from them as in “Socrates is a dead man,” if you regard their conjunction as destructive of one of them. Accordingly, the answer to the two questions is evident. In a case such as this, two contradictories are not enunciated of the same thing at the same time, but one term as it stands under dissolution or transmutation from the other, to which by itself it would be contradictory.
Peri.L7
277. Dubitatur quoque circa id quod ait: inest aliquid oppositorum quae consequitur contradictio; superflue enim videtur addi illa particula, quae consequitur contradictio. Omnia enim opposita consequitur contradictio, ut patet discurrendo in singulis; pater enim est non filius, et album non nigrum, et videns non caecum et cetera. Et ad hoc dicendum est quod opposita possunt dupliciter accipi: uno modo formaliter, idest secundum sua significata; alio modo denominative, seu subiective. Verbi gratia, pater et filius possunt accipi pro paternitate et filiatione, et possunt accipi pro eo qui denominatur pater vel filius. Rursus cum omnis distinctio fiat oppositione aliqua, ut dicitur in X metaphysicae, supponatur omnino distincta esse opposita.
There is also a question about something else that Aristotle says, namely, something opposed is present . . . from which a contradiction follows (21a21). The phrase from which a contradiction follows seems to be superfluous, for contradiction follows upon all opposites, as is evident in discoursing about singulars; for a father is not a son, and white is not black, and one seeing is not blind. Opposites, however, can be taken in two ways: formally (that is, according to what they signify), and denominatively (or subjectively). For example, father and son can be taken for paternity and filiation, or they can be taken for the one who is denominated a father or a son. But, again, since every distinction is made by some opposition, as is said in Metaphysics 10.3 (1054a20), it could be supposed that opposites are wholly distinct.
Peri.L7
Dicendum ergo est quod, licet ad omnia opposita seu distincta contradictio sequatur inter se formaliter sumpta, non tamen ad omnia opposita sequitur contradictio inter ipsa denominative sumpta. Quamvis enim pater et filius mutuam sui negationem inferant inter se formaliter, quia paternitas est non filiatio, et filiatio est non paternitas; in relatione tamen ad denominatum, contradictionem non necessario inferunt. Non enim sequitur, Socrates est pater; ergo non est filius; nec e converso. Ut persuaderet igitur Aristoteles quod non quaecunque opposita colligata impediunt divisam illationem (quia non illa quae habent contradictionem annexam formaliter tantum, sed illa quae habent contradictionem et formaliter et secundum rem denominatam), addidit: quae consequitur contradictio, in tertio scilicet denominato. Et usus est satis congrue vocabulo, scilicet, consequitur: contradictio enim ista in tertio est quodammodo extra ipsa opposita.
It must be pointed out, therefore, that although contradiction follows between all opposites or distinct things formally taken, nevertheless, contradiction does not follow upon all opposites denominatively taken. Father and son formally taken infer a mutual negation of one another, for paternity is not filiation and filiation is not paternity, but in respect to what is denominated they do not necessarily infer a contradiction. It does not follow, for example, that “Socrates is a father; therefore, he is not a son,” nor conversely. Aristotle, therefore, in order to establish that not all combined opposites prevent a divided inference (since those having a contradiction applying only formally do not prevent a divided inference, but those having a contradiction both formally and according to the thing denominated do prevent a divided inference) adds, from which a contradiction follows, namely, in the third thing denominated. And appropriately enough he uses the word follows, for the contradiction in the third thing denominated is in a certain way outside of the opposites themselves.
Peri.L7
278. Deinde cum dicit: vel etiam quando est etc., declarat quod ex non oppositis in tertio coniunctis secundum unum praedicatum, non universaliter possunt inferri partes divisim.
When he says, or, rather, when something opposed is present in it, it is never true (21a24), he explains that the parts cannot universally be inferred divisively in the case of a conjoined predicate in which there is a non-opposite as the third thing denominated.
Peri.L7
Et primo, hoc proponit quasi emendans quod immediate dixerat, subiungens: vel etiam quando est, scilicet oppositio inter terminos coniunctos, falsum est semper, scilicet inferre divisim; quasi diceret: dixi quod quando inest oppositio, non verum sed falsum est inferre divisim; quando autem non inest talis oppositio, verum est inferre divisim. Vel etiam ut melius dicatur, quod quando est oppositio, falsum est semper, quando autem non inest talis oppositio, non semper verum est. Et sic modificavit supradicta addendo ly semper, et, non semper. Et subdens exemplum quod non semper ex non oppositis sequatur divisio, ait: ut, Homerus est aliquid ut poeta; ergo etiam est? Non. Ex hoc coniuncto, est poeta, de Homero enunciato, altera pars, ergo Homerus est, non sequitur; et tamen clarum est quod istae duae partes colligatae, est et poeta, non habent oppositionem, ad quam sequitur contradictio. Igitur non semper ex non oppositis coniunctis illatio divisa tenet et cetera.
First, he proposes this, at: or, rather, when something opposed is present in it, that is, opposition between the terms conjoined. This is as if amending what he has just said, namely, it is always false to infer divisively. What he is saying, then, is this: I have said that when there is inherent opposition it is not true but false to infer divisively; but when there is not such opposition it is true to infer divisively; or, even better, when there is opposition it is always false, but when there is not such opposition it is not always true. That is, he modifies what he first said by the addition of always and not always. Then he adds an example to show that division does not always follow from non-opposites: for example, Homer is something, say, a poet. Is it therefore true to say also that Homer “is,” or not? From the conjoined predicate, is a poet, enunciated of Homer, one part, therefore, Homer is, does not follow; yet it is evident that these two conjoined parts, is and poet, do not have the opposition upon which contradiction follows. Therefore, in the case of conjoined non-opposites, a divided inference does not always hold.
Peri.L7
279. Deinde cum dicit: secundum accidens etc., probat hoc, quod modo dictum est, ex eo quod altera pars istius compositi, scilicet, est, in antecedente coniuncto praedicatur de Homero secundum accidens, idest ratione alterius, quoniam, scilicet poeta, praedicatur de Homero, et non praedicatur secundum se ly est de Homero; quod tamen infertur, cum concluditur: ergo Homerus est. Considerandum est hic quod ad solvendam illam conclusionem negativam, scilicet,- non semper ex non oppositis coniunctis infertur divisim,- sufficit unam instantiam suae oppositae universali affirmativae afferre.
When he says, the “is” here is predicated accidentally of Homer (21a26), he proves what he has said. One part of this composite, namely, is, is predicated of Homer in the antecedent conjunction accidentally, that is, by reason of another, namely, with regard to the “poet” which is predicated of Homer; it is not predicated as such of Homer. Nevertheless, this is what is inferred when one concludes therefore, Homer is. To validate his negative conclusion—namely, that it is not always true to infer divisively from conjoined non-opposites—it was sufficient to give one instance of the opposite of the universal affirmative.
Peri.L7
Et hoc fecit Aristoteles adducendo illud genus enunciationum, in quo altera pars coniuncti est aliquid pertinens ad actum animae. Loquimur enim modo de Homero vivente in poematibus suis in mentibus hominum. In his siquidem enunciationibus partes coniunctae non sunt oppositae in tertio, et tamen non licet inferre utramque partem divisim. Committitur enim fallacia secundum quid ad simpliciter. Non enim valet, Caesar est laudatus, ergo est: et simile est de esse in effectu dependente in conservari. Quomodo autem intelligenda sit ratio ad hoc adducta ab Aristotele in sequenti particula dicetur.
To do this, Aristotle introduces that genus of enunciation in which one part of the conjunction is something pertaining to an act of the mind (for we are speaking only of Homer living in his poems in the minds of men). In such enunciations the parts conjoined are not opposed in the third thing denominated; nevertheless, it is not licit to infer each part divisively, for the fallacy of going from the relative to the absolute will be committed. For example, it is not valid to say, “Caesar is praiseworthy, therefore he is,” which is a parallel case, namely, of an effect whose existence requires maintenance. Aristotle will explain in the following sections of the text how the reasoning in the above text is to be understood.
Peri.L7
280. Deinde cum dicit: quare in quantiscunque etc., respondet parti affirmativae quaestionis, quando scilicet ex coniunctis licet inferre divisim. Et ponit duas conditiones oppositas supradictis debere convenire in unum, ad hoc ut possit fieri talis consequentia; scilicet, quod nulla inter partes coniuncti oppositio sit, et quod secundum se praedicentur.
When he says, therefore, in whatever predications no contrariety is present (21a29), he replies to the affirmative part of the question, that is, when it is licit to infer divisively from conjoined predicates. He maintains that two conditions—opposed to what has been said earlier in this portion of the text—must combine in one enunciation in order that such a consequence be effected: there must be no opposition between the parts conjoined, and they must be predicated per se.
Peri.L7
Unde dicit inferendo ex dictis: quare in quantiscunque praedicamentis, idest praedicatis ordine quodam adunatis, neque contrarietas aliqua, in cuius ratione ponitur contradictio in tertio (contraria enim sunt quae mutuo se ab eodem expellunt), aut universaliter nulla oppositio inest, ex qua scilicet sequatur contradictio in tertio, si definitiones pro nominibus sumantur.
He says, then, inferring from what has been said: therefore, in whatever predications, that is, predicates joined in a certain order, no contrariety, in virtue of which contradiction is posited in the third thing denominated (for contraries mutually remove each other from the same thing), is present, or universally, no opposition is present, that is, upon which a contradiction follows in the third thing denominated, when definitions are taken in place of the names.
Peri.L7
Dixit hoc, quia licet in quibusdam non appareat oppositio, solis nominibus positis, sicut, homo mortuus, et in quibusdam appareat, ut, vivum mortuum; hoc tamen non obstante, si, positis nominum definitionibus loco nominum, oppositio appareat, inter opposita collocamus. Sicut, verbi gratia, homo mortuus, licet oppositionem non praeseferat, tamen si loco hominis et mortui eorum definitionibus utamur, videbitur contradictio. Dicemus enim corpus animatum rationale, corpus inanimatum irrationale. In quantiscunque, inquam, coniunctis nulla est oppositio, et secundum se, et non secundum accidens praedicantur, in his verum erit dicere et simpliciter, idest divisim quod fuerat coniunctim enunciatum.
He says this because it may be the case that the opposition is not apparent from the names alone, as in “dead man,” and again it may be, as in “living dead,” but whether apparent or not it will be evident that we are putting together opposites if we posit the definitions of the names in place of the names. For example, in the case of “dead man,” if we replace “man” and “dead” with their definitions, the contradiction will be evident, for what we are saying is “rational animate body, irrational inanimate body.” In whatever conjoined predicates, then, there is no opposition, and where predicates are predicated per se and not accidentally, in these it will also be true to predicate them singly, that is, say divisively what had been enunciated conjointly.
Peri.L7
281. Ad evidentiam secundae conditionis hic positae, nota quod ly secundum se potest dupliciter accipi:
In order to make this second condition clear, it should be noted that per se can be taken in two ways:
Peri.L7
uno modo positive, et sic dicit perseitatem primi, secundi, universaliter, quarti modi;
positively, and thus it refers to the essentiality of the first, of the second, and of the fourth mode universally;
Peri.L7
alio modo negative, et sic idem sonat quod non per aliud.
or negatively, and thus it means the same as not through something else.
Peri.L7
Rursus considerandum est quod cum Aristoteles dixit de praedicato coniuncto quod, secundum se praedicetur, ly secundum se potest ad tria referri,
It should also be noted that when Aristotle says of a conjoined predicate that it is predicated “per se,” the per se can be referred to three things:
Peri.L7
scilicet, ad partes coniuncti inter se,
to the parts of the conjunction among themselves,
Peri.L7
ad totum coniunctum respectu subiecti,
to the whole conjunction with respect to the subject,
Peri.L7
et ad partes coniuncti respectu subiecti.
and to the parts of the conjoined predicate with respect to the subject.
Peri.L7
Si ergo accipiatur ly secundum se positive, licet non falsus, extraneus tamen a mente Aristotelis reperitur sensus ad quodcunque illorum trium referatur. Licet enim valeat, est homo risibilis, ergo est homo et est risibilis, et, est animal rationale, ergo est animal et est rationale; tamen his oppositae inferunt similes consequentias. Dicimus enim, est albus musicus, ergo est musicus et est albus: ubi nulla est perseitas, sed est coniunctio per accidens, tam inter partes inter se, quam inter totum et subiectum, quam etiam inter partes et subiectum.
Now if per se is taken positively, although it will not be false, nevertheless in reference to any of these three the meaning will be found to be foreign to the mind of Aristotle. For although these are valid: “He is a risible man; therefore, he is man and he is risible” and “He is a rational animal; therefore, he is animal and he is rational,” nevertheless the opposite kind of predication infers consequences in a similar way. For example, there is no essentiality in “He is a white musician; therefore, he is white and he is a musician”; rather, there is an accidental conjunction, not only between the parts among themselves and between the whole and the subject, but even between the parts and the subject.
Peri.L7
Liquet igitur quod non accipit Aristoteles ly secundum se positive, ex eo quod vana fuisset talis additio, quae ab oppositis non facit in hoc differentiam. Ad quid enim addidit, secundum se, et non, secundum accidens, si tam illae quae sunt secundum se, modo exposito, quam illae quae sunt secundum accidens ex coniuncto, inferunt divisum? Si vero accipiatur secundum se, negative, idest, non per aliud, et referatur ad partes coniuncti inter se, falsa invenitur regula. Nam non licet dicere, est bonus citharoedus; ergo est bonus et citharoedus; et tamen ars citharizandi et bonitas eius sine medio coniunguntur. Et similiter contingit, si referatur ad totum coniunctum respectu subiecti, ut in eodem exemplo apparet. Totum enim hoc, citharoedus bonus, non propter aliud convenit homini; et tamen non infert, ut dictum est, divisionem. Superest ergo ut ad partem coniuncti respectu subiecti referatur, et sit sensus: quando aliqua coniunctim praedicata, secundum se, idest, non per aliud, praedicantur, idest, quod utraque pars praedicatur de subiecto non propter alteram, sed propter seipsam et subiectum, tunc ex coniuncto infertur divisa praedicatio.
It is evident, therefore, that Aristotle is not taking per se positively, for an addition that does not differentiate this kind of predication from the opposed kind of predication would be useless. Why add “per se and not accidentally,” if both those that are per se in the way explained and those that are conjoined accidentally infer divisively? If “per se” is taken negatively, that is, as not through another, and is referred to the parts of the conjoined predicate among themselves, the rule is found to be false. It is not licit, for example, to say, “He is a good lute player, therefore he is good and a lute player”; yet the art of lute-playing and its goodness are conjoined without anything as a medium. And the case is the same if it is referred to the whole conjoined predicate with respect to the subject, as is clear in the same example, for the whole, “good lute player,” does not belong to man on account of another, and yet it does not infer the division, as has already been said. Therefore, “per se” is referred to the parts of the conjoined predicate with respect to the subject, and the meaning is that when the predicates are conjointly predicated per se, that is, not through another (so that each part is predicated of the subject not on account of another but on account of itself and the subject), then a divided predication is inferred from the conjoined predication.
Peri.L7
282. Et hoc modo exponunt Averroes et Boethius; et vera invenitur regula, ut inductive facile manifestari potest, et ratio ipsa suadet. Si enim partes alicuius coniuncti praedicati ita inhaerent subiecto quod neutra propter alteram insit, earum separatio nihil habet quod veritatem impediat divisarum. Est et verbis Aristotelis consonus sensus iste. Quoniam et per hoc distinguit inter enunciationes ex quibus coniunctum infert divisam praedicationem, et eas quibus haec non inest consequentia. Istae siquidem ultra habentes oppositiones in adiecto, sunt habentes praedicatum coniunctum, cuius una partium alterius est ita determinatio, quod nonnisi per illam subiectum respicit, sicut apparet in exemplo ab Aristotele adducto, Homerus est poeta. Est siquidem ibi non respicit Homerum ratione ipsius Homeri, sed praecise ratione poesis relictae; et ideo non licet inferre, ergo Homerus est. Et simile est in negativis. Si quis enim dicat, Socrates non est paries, non licet inferre, ergo Socrates non est, eadem ratione, quia esse non est negatum de Socrate, sed de pariete in Socrate.
This is the way in which Averroes and Boethius explain this and, explained in this way, a true rule is found, as can easily be manifested inductively. Moreover, the reasoning is compelling. For if the parts of some conjoined predicate so inhere in the subject that neither of them is in it on account of another, their separation produces nothing that could impede the truth of the divided predicates. And this meaning is consonant with the words of Aristotle, for by this he also distinguishes between enunciations in which the conjoined predicate infers a divided predicate, and those in which this consequence is not inherent. For, besides the predicates having opposition in the additional determining element, there are those with a conjoined predicate in which one part is a determination of the other in such a way that only through it does it regard the subject, as is evident in Aristotle’s example, Homer is a poet. The “is” does not regard Homer by reason of Homer himself, but precisely by reason of the poetry he left. Hence it is not licit to infer, “Therefore, Homer is.” The same is true with respect to negative enunciations of this type, for it is not licit to infer from “Socrates is not a wall” that “therefore, Socrates is not.” And the reason is the same: “to be” is not denied of Socrates, but of “wallness” in Socrates.
Peri.L7
283. Et per hoc patet qualiter sit intelligenda ratio in textu superiore adducta. Accipitur enim ibi, secundum se negative, modo hic exposito, et secundum accidens, idest propter aliud. In eadem ergo significatione est usus ly secundum accidens, solvendo hanc et praecedentem quaestionem: utrobique enim intellexit secundum accidens, idest, propter aliud, coniuncta, sed ad diversa retulit. Ibi namque ly secundum accidens determinabat coniunctionem duorum praedicatorum inter se; hic vero determinat partem coniuncti praedicati in ordine ad subiectum. Unde ibi, album et musicum, inter ea quae secundum accidens sunt, numerabantur; hic autem non.
Accordingly, it is evident how the reasoning in the text above is to be understood. Per se is taken negatively in the way explained here, and “accidentally” as “on account of another.” The accidentally is used with the same signification in solving this and the preceding question. In both he understands “accidentally” to mean conjoined on account of another, but it is referred to diverse things. In the preceding question accidentally determines the way in which two predicates are conjoined among themselves; in the latter question it determines the way in which the part of the conjoined predicate is ordered to the subject. Hence, in the former, white and musician are numbered among the things that are accidental, but in the latter they are not.
Peri.L7
284. Sed occurrit circa hanc expositionem dubitatio non parva. Si enim ideo non licet ex coniuncto inferre divisim, quia altera pars coniuncti non respicit subiectum propter se, sed propter alteram partem (ut dixit Aristoteles de ista enunciatione, Homerus est poeta), sequetur quod numquam a tertio adiacente ad secundum erit bona consequentia: quia in omni enunciatione de tertio adiacente, est respicit subiectum propter praedicatum et non propter se et cetera.
This exposition seems a bit dubious, however. For if it is not licit to infer divisively from a conjoined predicate because one part of the conjoined predicate does not regard the subject on account of itself but on account of another part (as Aristotle says of the enunciation, Homer is a poet), it will follow that there will never be a good consequence from the third determinant to the second, since in every enunciation with a third determinant, “is” regards the subject on account of the predicate and not on account of itself.
Peri.L7
285. Ad huius difficultatis evidentiam, nota primo hanc distinctionem. Aliud est tractare regulam, quando ex tertio adiacente infertur secundum et quando non, et aliud quando ex coniuncto fit illatio divisa et quando non. Illa siquidem est extra propositum, istam autem venamur. Illa compatitur varietatem terminorum, ista non. Si namque unus terminorum, qui est altera pars coniuncti, secundum significationem seu suppositionem varietur in separatione, non infertur ex coniuncto praedicato illudmet divisim, sed aliud.
To make this difficulty clear, we must first note a distinction. It is one thing to treat of the rule when inferring a second determinant from a third determinant, and when not; it is quite another thing when a divided inference is made from a conjoined predicate, and when not. The former is an additional point; the latter is the question we have been inquiring about. The former is compatible with variety of the terms, the latter not. For if one of the terms which is one part of a conjoined predicate will be varied according to signification, or supposition when taken separately, it is not inferred divisively from the conjoined predicate, but the other is.
Peri.L7
Nota secundo hanc propositionem: cum ex tertio adiacente infertur secundum, non servatur identitas terminorum. Liquet ista quoad illum terminum, est. Dictum siquidem fuit supra a sancto Thoma, quod aliud importat est secundum adiacens, et aliud est tertium adiacens. Illud namque importat actum essendi simpliciter, hoc autem habitudinem inhaerentiae vel identitatis praedicati ad subiectum. Fit ergo varietas unius termini cum ex tertio adiacente infertur secundum, et consequenter non fit illatio divisi ex coniuncto.
Second, note this proposition: when a second determinant is inferred from a third, identity of the terms is not kept. This is evident with respect to the term “is.” Indeed, St. Thomas said above that “is” as the second determinant implies one thing and “is” as the third determinant another. The former implies the act of being simply, the latter implies the relationship of inherence, or identity of the predicate with the subject. Therefore, when the second determinant is inferred from the third, one term is varied, and consequently an inference is not made of the divided from the conjoined.
Peri.L7
Unde praelucet responsio ad obiectionem, quod, licet ex tertio adiacente quandoque possit inferri secundum, numquam tamen ex tertio adiacente licet inferri secundum tamquam ex coniuncto divisum, quia inferri non potest divisim, cuius altera pars ipsa divisione perit. Negetur ergo consequentia obiectionis et ad probationem dicatur quod, optime concludit quod talis illatio est illicita infra limites illationum, quae ex coniuncto divisionem inducunt, de quibus hic Aristoteles loquitur.
Accordingly, the response to the objection is clear, for although the second determinant can sometimes be inferred from the third, it is never licit for the second to be inferred from the third as divided from conjoined, because you cannot infer divisively when one part is destroyed by that very division. Therefore, let the consequence of the objection be denied and for proof let it be said that the conclusion that such an inference is illicit under the limits of inferences which induce division from a conjoined predicate is good, for this is what Aristotle is speaking of here.
Peri.L7
286. Sed contra hoc instatur. Quia etiam tanquam ex coniuncto divisa fit illatio, Socrates est albus, ergo est, per locum a parte in modo ad suum totum, ubi non fit varietas terminorum. Et ad hoc dicitur quod licet homo albus sit pars in modo hominis (quia nihil minuit de hominis ratione albedo, sed ponit hominem simpliciter), tamen est album non est pars in modo ipsius est, eo quod pars in modo est universale cum conditione non minuente, ponente illud simpliciter. Clarum est autem quod album minuit rationem ipsius est, et non ponit ipsum simpliciter: contrahit enim ad esse secundum quid. Unde apud philosophos, cum fit aliquid album, non dicitur generari, sed generari secundum quid.
But the objection is raised against this that in the case of “Socrates is white; therefore, he is,” a divided inference can be made as from a conjoined predicate, in virtue of the argument that we can go from what is in the mode of part to its whole as long as the terms remain the same. The answer to this is as follows. It is true that white man is a part in the mode of man (because white diminishes nothing of the notion of man but posits man simply); “is white,” however, is not a part in the mode of “is,” because a part in the mode of its whole is a universal, the condition not diminishing the positing of it simply. But it is evident that “white” diminishes the notion of “is,” and does not posit it simply, for it contracts it to relative being. Hence, when something becomes white, philosophers do not say that it is generated, but generated relatively.
Peri.L7
287. Sed instatur adhuc quia secundum hoc, dicendo, est animal, ergo est, fit illatio divisa per eumdem locum. Animal enim non minuit rationem ipsius est. Ad hoc est dicendum quod ly est, si dicat veritatem propositionis, manifeste peccatur a secundum quid ad simpliciter. Si autem dicat actum essendi, illatio est bona, sed non est de tertio, sed de secundo adiacente.
In accordance with this, the objection is raised that in saying, “It is an animal; therefore, it is,” a divided inference is made in virtue of the same argument; for “animal” does not diminish the notion of “is” itself. The answer to this is that if the “is” asserts the truth of a proposition, the fallacy is committed of going from the relative to the absolute; if the “is” asserts the act of being, the inference is good, but it is of the second determinant, not of the third.
Peri.L7
288. Potest ulterius dubitari circa principale: quia sequitur, est quantum coloratum, ergo est quantum, et, est coloratum; et tamen coloratum respicit subiectum mediante quantitate: ergo non videtur recta expositio supra adducta. Ad hoc et similia dicendum est quod coloratum non ita inest subiecto per quantitatem quod sit eius determinatio et ratione talis determinationis subiectum denominet, sicut bonitas artem citharisticam determinat; cum dicitur, est citharoedus bonus; sed potius subiectum ipsum primo coloratum denominatur, quantum vero secundario coloratum dicitur, licet color media quantitate suscipiatur. Unde notanter supra diximus, quod tunc altera pars coniuncti praedicatur per accidens, quando praecise denominat subiectum, quia denominat alteram partem. Quod nec in similibus instantiis invenitur.
There is another doubt, this time about the principle in the exposition. For this follows, “It is a colored quantity, therefore it is a quantity and it is colored.” But “colored” regards the subject through the medium of quantity. Therefore, the exposition given above does not seem to be correct. The answer to this and to similar objections is that “colored” is not so present in a subject by means of quantity that it is its determination, and by reason of such a determination denominates the subject; as “goodness,” for instance, determines the art of lute-playing when we say “He is a good lute player.” Rather, the subject itself is first denominated “colored” and quantity is called “colored” secondarily, although color is received through the medium of quantity. Hence, we made a point of saying earlier that one part of a conjoined predicate is predicated accidentally when it denominates the subject precisely because it denominates the other part. This is not the case here, nor in similar instances.
Peri.L7
289. Deinde cum dicit: quod autem non est etc., excludit quorumdam errorem qui, quod non est, esse tali syllogismo concludere satagebant: quod est, opinabile est. Quod non est, est opinabile. Ergo quod non est, est. Hunc siquidem processum elidit Aristoteles destruendo primam propositionem, quae partem coniuncti in subiecto divisim praedicat, ac si diceret: est opinabile, ergo est. Unde assumendo subiectum conclusionis illorum ait: quod autem non est; et addit medium eorum, quoniam opinabile est; et subdit maiorem extremitatem, non est verum dicere, esse aliquid. Et causam assignat, quia talis opinatio non propterea est, quia illud sit, sed potius quia non est.
When he says, in the case of non-being, however (21a32), he excludes the error of those who were satisfied to conclude that what is not, is. This is the syllogism they use: “That which is, is ‘opinionable’; that which is not, is ‘opinionable’; therefore, what is not, is.” Aristotle destroys this process of reasoning by destroying the first proposition, which predicates divisively a part of what is conjoined in the subject, as if it said, “It is ‘opinionable’; therefore, it is.” Hence, assuming the subject of their conclusion, he says, in the case of that which is not, however; and he adds their middle term, because it is a matter of opinion; then he adds the major extreme, it is not true to say that it is something. He then assigns the cause: it is not because it is but rather because it is not that there is such opinion.

Let us grant that of mutually related enunciations, contradictories are those opposed to each other by being related in a certain way according to “to be” and “not to be.” For example, the negation of “man is” is “man is not,” and not “non-man is”; and of “man is white,” “man is not white,” and not “man is non-white.” For if this is not so, it will be true to say that “wood” is non-white man, since of anything either the affirmation or the negation is true. Now, in those in which “to be” is not the determining word added, that which is said in place of “to be” will effect the same thing. For example, the negation of “man walks” will be “man does not walk,” and not “non-man walks.” The reason, of course, is that there is no difference between “man walks” and “man is walking.” And if this is always the case, then the negation of “possible to be” will be “possible not to be,” and not “not possible to be.”
Peri.L8
Quare si hoc modo ubique, et eius, quae est, possibile esse, negatio erit possibile non esse, sed non ea quae est, nonpossibile esse. Videtur autem idem posse et esse et non esse. Omne enim quod est possibile dividi, vel ambulare, et non ambulare, et non dividi possibile est. Ratio autem est, quoniam omne quod sic possibile est, non semper in actu est; quare inerit ipsi etiam negatio: potest enim et non ambulare quod est ambulativum, et non videri quod est visibile. At vero impossibile est de eodem oppositas veras esse affirmationes et negationes.
21b12. However, it seems that the same thing is possible to be and possible not to be. For everything that has the possibility to be cut or to walk has the possibility not to be cut and not to walk, and the reason is that everything that is possible in this way is not always in act, and so the negation will also be inherent in it. For that which could walk could also not walk, and that which could be seen could not be seen. But it is impossible that contradictions in respect to the same thing be true. Therefore, the negation of “possible to be” is not “possible not to be.”
Peri.L8
Non igitur eius quae est, possibile esse, negatio est haec, possibile non esse. Contingit autem ex his, aut idem affirmare et negare simul de eodem, aut non secundum esse vel non esse, quae opponuntur, fieri affirmationes et negationes. Si ergo illud impossibile est, hoc erit magis eligendum.
21b19. For it follows from what we have said either that the same thing is asserted and denied at once of the same subject or that assertions and denials of modals are not made by the addition of “to be” or “not to be” respectively. If the former alternative is impossible, the latter must obtain.
Peri.L8
290. Postquam determinatum est de enunciationibus, quarum partibus aliud additur tam remanente quam variata unitate, hic intendit declarare quid accidat enunciationi, ex eo quod aliquid additur, non suis partibus, sed compositioni eius.
Now that he has treated enunciations in which something added to the parts leaves the unity intact on the one hand, and varies it on the other, Aristotle begins to explain what happens to the enunciation when something is added not to its parts, but to its composition.
Peri.L8
Et circa hoc duo facit:
About this he does two things.
Peri.L8
primo, determinat de oppositione earum;
First, he explains their opposition;
Peri.L8
secundo, de consequentiis; ibi: consequentiae vero et cetera.
second, he treats of the consequences of their opposition, at: logical sequences result from modals ordered thus (22a14; [309]).
Peri.L8
Circa primum duo facit:
About the first he does two things.
Peri.L8
primo, proponit quod intendit;
First, he proposes the question he intends to consider;
Peri.L8
secundo, exequitur; ibi: nam si eorum et cetera.
second, he begins his consideration, at: let us grant that of mutually related enunciations (21a38; [296]).
Peri.L8
Proponit ergo quod iam perspiciendum est, quomodo se habeant affirmationes et negationes enunciationum de possibili et non possibili et cetera. Et causam subdit: habent enim multas dubitationes speciales.
He proposes that we must now investigate the way in which affirmations and negations of the possible and not possible are related. He gives the reason when he adds, a question of considerable difficulty (21a34).
Peri.L8
Sed antequam ulterius procedatur, quoniam de enunciationibus, quae modales vocantur, sermo inchoatur, praelibandum est esse quasdam modales enunciationes, et qui et quot sunt modi reddentes propositiones modales; et quid earum sit subiectum et quid praedicatum; et quid sit ipsa enunciatio modalis; quisque sit ordo earum ad praecedentes; et quae necessitas sit specialem faciendi tractatum de his.
However, before we proceed with the consideration of enunciations that are called modal, we must first see that there are such things as modal enunciations, and which and how many modes render propositions modal; we must also know what their subject is and their predicate, what the modal enunciation itself is, what the order is between modal enunciations and the enunciations already treated, and finally, why a special treatment of them is necessary.
Peri.L8
291. Quia ergo possumus dupliciter de rebus loqui;
We can speak about things in two ways:
Peri.L8
uno modo, componendo rem unam cum alia,
in one way, composing one thing with another;
Peri.L8
alio modo, compositionem factam declarando qualis sit,
in the other, declaring the kind of composition that exists between the two things.
Peri.L8
insurgunt duo enunciationum genera;
To signify these two ways of speaking about things we form two kinds of enunciations.
Peri.L8
quaedam scilicet enunciantes aliquid inesse vel non inesse alteri, et hae vocantur de inesse, de quibus superius habitus est sermo;
One kind enunciates that something belongs or does not belong to something. These are called absolute enunciations, which we have already discussed.
Peri.L8
quaedam vero enunciantes modum compositionis praedicati cum subiecto, et hae vocantur modales, a principaliori parte sua, modo scilicet. Cum enim dicitur, Socratem currere est possibile, non enunciatur cursus de Socrate, sed qualis sit compositio cursus cum Socrate, scilicet possibilis. Signanter autem dixi modum compositionis, quoniam modus in enunciatione positus duplex est.
The other enunciates the mode of composition of the predicate with the subject. These are called modal, from their principal part, the mode. For when we say, “That Socrates run is possible,” it is not the running of Socrates that is enunciated but the kind of composition there is between running and Socrates—in this case, possible. I have said “mode of composition” expressly, for there are two kinds of mode posited in the enunciation.
Peri.L8
Quidam enim determinat verbum, vel ratione significati ipsius verbi ut Socrates currit velociter, vel ratione temporis consignificati, ut Socrates currit hodie;
One modifies the verb, either with respect to what it signifies, as in “Socrates runs swiftly,” or with respect to the time signified along with the verb, as in “Socrates runs today.”
Peri.L8
quidam autem determinat compositionem ipsam praedicati cum subiecto; sicut cum dicitur, Socratem currere est possibile.
The other kind modifies the very composition of the predicate with the subject, as in the example, “It is possible that Socrates run.”
Peri.L8
In illis namque determinatur qualis cursus insit Socrati, vel quando; in hac autem, qualis sit coniunctio cursus cum Socrate. Modi ergo non illi qui rem verbi, sed qui compositionem determinant, modales enunciationes reddunt, eo quod compositio veluti forma totius totam enunciationem continet.
The former determines how or when running is in Socrates; the latter determines the kind of conjunction there is between running and Socrates. The former, which affects the actuality of the verb, does not make a modal enunciation. Only the modes that affect the composition make a modal enunciation, the reason being that the composition, as the form of the whole, contains the whole enunciation.
Peri.L8
292. Sunt autem huiusmodi modi quatuor proprie loquendo, scilicet possibile et impossibile, necessarium et contingens. Verum namque et falsum, licet supra compositionem cadant cum dicitur, Socratem currere est verum, vel hominem esse quadrupedem est falsum, attamen modificare proprie non videntur compositionem ipsam. Quia modificari proprie dicitur aliquid, quando redditur aliquale, non quando fit secundum suam substantiam. Compositio autem quando dicitur vera, non aliqualis proponitur, sed quod est: nihil enim aliud est dicere, Socratem currere est verum, quam quod compositio cursus cum Socrate est. Et similiter quando est falsa, nihil aliud dicitur, quam quod non est: nam nihil aliud est dicere, Socratem currere est falsum, quam quod compositio cursus cum Socrate non est. Quando vero compositio dicitur possibilis aut contingens, iam non ipsam esse, sed ipsam aliqualem esse dicimus: cum siquidem dicitur, Socratem currere est possibile, non substantificamus compositionem cursus cum Socrate, sed qualificamus, asserentes illam esse possibilem. Unde Aristoteles hic modos proponens, veri et falsi nullo modo meminit, licet infra verum et non verum inferat, propter causam ibi assignandam.
This kind of mode, properly speaking, is fourfold: possible, impossible, necessary, and contingent. True and false are not included because, strictly speaking, they do not seem to modify the composition even though they fall upon the composition itself, as is evident in “That Socrates runs is true,” and “That man is four-footed is false.” For something is said to be modified in the proper sense of the term when it is caused to be in a certain way, not when it comes to be according to its substance. Now, when a composition is said to be true, it is not proposed that it is in a certain way, but that it is. To say, “That Socrates runs is true,” for example, is to say that the composition of running with Socrates is. The case is similar when it is false, for what is said is that it is not; for example, to say, “That Socrates runs is false” is to say that the composition of running with Socrates is not. On the other hand, when the composition is said to be possible or contingent, we are not saying that it is but that it is in a certain way. For example, when we say, “It is possible that Socrates run,” we do not make the composition of running with Socrates substantial, but we qualify it, asserting that it is possible. Consequently, Aristotle does not mention the true and false at all in proposing the modes, although later on he infers the true and the not true, and assigns the reason for it where he does this.
Peri.L8
293. Et quia enunciatio modalis duas in se continet compositiones, alteram inter partes dicti, alteram inter dictum et modum, intelligendum est eam compositionem modificari, idest, quae est inter partes dicti, non eam quae est inter modum et dictum. Quod sic perpendi potest.
Since the modal enunciation contains two compositions, one between the parts of what is said, the other between what is said and the mode, it must be understood that it is the former composition that is modified, that is, the composition between the parts of what is said, not the composition between what is said and the mode.
Peri.L8
Huius enunciationis modalis, Socratem esse album est possibile, duae sunt partes; altera est, Socratem esse album, altera est, possibile. Prima dictum vocatur, eo quod est id quod dicitur per eius indicativam, scilicet, Socrates est albus: qui enim profert hanc, Socrates est albus, nihil aliud dicit nisi Socratem esse album: secunda vocatur modus, eo quod modi adiectio est. Prima compositionem quandam in se continet ex Socrate et albo; secunda pars primae opposita compositionem aliquam sonat ex dicti compositione et modo. Prima rursus pars, licet omnia habeat propria, subiectum scilicet, et praedicatum, copulam et compositionem, tota tamen subiectum est modalis enunciationis; secunda autem est praedicatum.
This can be seen in an example. In the modal enunciation, “That Socrates be white is possible,” there are two parts: one, “That Socrates be white,” the other, “is possible.” The first is called the dictum because it is that which is asserted by the indicative, namely, “Socrates is white”; for in saying “Socrates is white” we are simply saying that Socrates is white. The second part is called the mode because it is the addition of a restriction. The first part of the modal enunciation consists of a certain composition of Socrates and white; the second part, opposed to the first, indicates a composition from the composition of dictum and mode. Again, the first part, although it has all the properties of an enunciation—subject, predicate, copula, and composition—is, in its entirety, the subject of the modal enunciation; the second part (the mode) is the predicate.
Peri.L8
Dicti ergo compositio subiicitur et modificatur in enunciatione modali. Qui enim dicit, Socratem esse album est possibile, non significat qualis est coniunctio possibilitatis cum hoc dicto, Socratem esse album, sed insinuat qualis sit compositio partium dicti inter se, scilicet albi cum Socrate, scilicet quod est compositio possibilis. Non dicit igitur enunciatio modalis aliquid inesse, vel non inesse, sed dicti potius modum enunciat. Nec proprie componit secundum significatum, quia compositionis non est compositio, sed rerum compositioni modum apponit. Unde nihil aliud est enunciatio modalis, quam enunciatio dicti modificativa.
In a modal enunciation, therefore, the composition of the dictum is subjected and modified; for when we say, “That Socrates be white is possible,” it does not signify the kind of conjunction of possibility there is with the dictum “that Socrates be white,” but it implies the kind of composition there is of the parts of the dictum among themselves (that is, of white with Socrates)—namely, that it is a possible composition. The modal enunciation, therefore, does not say that something is present in or not present in a subject, but rather, it enunciates a mode of the dictum. Nor, properly speaking, does it compose according to what is signified, since it is not a composition of the composition; rather, it adds a mode to the composition of the things. Hence the modal enunciation is simply an enunciation in which the dictum is modified.
Peri.L8
294. Nec propterea censenda est enunciatio plures modalis, quia omnia duplicata habeat: quoniam unum modum de unica compositione enunciat, licet illius compositionis plures sint partes. Plura enim illa ad dicti compositionem concurrentia, veluti plura ex quibus fit unum subiectum concurrunt, de quibus dictum est supra quod enunciationis unitatem non impediunt. Sicut nec cum dicitur, domus est alba, est enunciatio multiplex, licet domus ex multis consurgat partibus.
Because the modal enunciation has everything duplicated, it must not on that account be thought to be many. It enunciates one mode of only one composition, although there are many parts of that composition. The many concurring for the composition of the dictum are like the many that concur to make one subject, of which it was said above that it does not impede the unity of the enunciation. The enunciation, “The house is white,” is also a case in point, for it is not multiple, although a house is built of many parts.
Peri.L8
295. Merito autem est, post enunciationes de inesse, de modalibus tractandum, quia partes naturaliter sunt toto priores, et cognitio totius ex partium cognitione dependet; et specialis sermo de his est habendus, quia proprias habet difficultates. Notavit quoque Aristoteles in textu multa. Horum ordinem scilicet, cum dixit: his vero determinatis etc.; modos qui et quot sunt, cum eos expressit et inseruit; variationem eiusdem modi, per affirmationem et negationem, cum dixit: possibile et non possibile, contingens et non contingens; necessitatem cum addidit: habent enim multas dubitationes proprias et cetera.
Modal enunciations are rightly treated after the absolute enunciation, for parts are naturally prior to the whole, and knowledge of the whole depends on knowledge of the parts. Moreover, a special discussion of them was necessary because the modal enunciation has its own peculiar difficulties. Aristotle indicates in his text many of the things we have taken up here: the order of modal enunciations, when he says, having determined these things (21a34); what and how many modes there are when he expresses and lists them; the variation of the same mode by affirmation and negation when he says, the possible and not possible, contingent and not contingent; and the necessity of treating them, when he adds, a question of considerable difficulty.
Peri.L8
296. Deinde cum dicit: nam si eorum etc., exequitur tractatum de oppositione modalium.
Then he investigates the opposition of modal enunciations, where he says, let us grant that of mutually related enunciations (21a38).
Peri.L8
Et circa hoc duo facit:
About this he does two things.
Peri.L8
primo, movendo quaestionem arguit ad partes;
First, he presents the question, and in so doing gives arguments for the parts;
Peri.L8
secundo, determinat veritatem; ibi: contingit autem et cetera.
second, he determines the truth, at: for it follows from what we have said (21b19; [303]).
Peri.L8
Est autem dubitatio: an in enunciationibus modalibus fiat contradictio negatione apposita ad verbum dicti, quod dicit rem; an non, sed potius negatione apposita ad modum qui qualificat.
The question with respect to the opposition of modals is this: Is a contradiction made in modal enunciations by a negation added to the verb of the dictum, which expresses what is; or is it not, but rather by a negation added to the mode which qualifies?
Peri.L8
Et primo, arguit ad partem affirmativam, quod scilicet addenda sit negatio ad verbum;
Aristotle first argues for the affirmative part, that the negation must be added to the verb;
Peri.L8
secundo, ad partem negativam, quod non apponenda sit negatio ipsi verbo; ibi: videtur autem et cetera.
second, he argues for the negative part, that the negation must not be added to the verb, at: however, it seems that the same thing (21b12; [302]).
Peri.L8
297. Intendit ergo primo tale argumentum; si complexorum contradictiones attenduntur penes esse et non esse (ut patet inductive in enunciationibus substantivis de secundo adiacente et de tertio, et in adiectivis), contradictionesque omnium hoc modo sumendae sunt, contradictoria huius, possibile esse, erit, possibile non esse, et non illa, non possibile esse. Et consequenter apponenda est negatio verbo, ad sumendam oppositionem in modalibus. Patet consequentia, quia cum dicitur, possibile esse, et, possibile non esse, negatio cadit supra esse. Unde dicit: nam si eorum, quae complectuntur, idest complexorum, illae sibi invicem sunt oppositae contradictiones, quae secundum esse vel non esse disponuntur, idest in quarum una affirmatur esse, et in altera negatur.
His first argument is this. If of combined things, contradictions are those related according to “to be” and “not to be” (as is clear inductively in substantive enunciations with a second determinant, in those with a third determinant, and in adjectival enunciations), and all contradictions must be obtained in this way, the contradictory of possible to be will be possible not to be, and not not possible to be. Consequently, the negation must be added to the verb to get opposition in modal enunciations. The consequence is clear, for when we say “possible to be” and possible not to be” the negation falls on “to be.” Accordingly, he says, let us grant that of those things that are combined, that is, of complex things, contradictions are those opposed to each other which are disposed according to “to be” and “not to be,” that is, in one of which “to be” is affirmed and in the other denied.
Peri.L8
298. Et subdit inductionem, inchoans a secundo adiacente: ut, eius enunciationis quae est, esse hominem, idest, homo est, negatio est, non esse hominem, ubi verbum negatur, idest, homo non est; et non est eius negatio ea quae est, esse non hominem, idest, non homo est: haec enim non est negativa, sed affirmativa de subiecto infinito, quae simul est vera cum illa prima, scilicet, homo est.
He goes on to give an induction, beginning with an enunciation having a second determinant. The negation of man is is “man is not,” in which the verb is negated. The negation of “man is” is not non-man is, for this is not the negative but the affirmative of the infinite subject, which is true at the same time as the first enunciation, “man is.”
Peri.L8
299. Deinde prosequitur inductionem in substantivis de tertio adiacente: ut, eius quae est, esse album hominem idest, ut illius enunciationis, homo est albus, negatio est, non esse album hominem, ubi verbum negatur, idest, homo non est albus; et non est negatio illius ea, quae est, esse non album hominem, idest, homo est non albus. Haec enim non est negativa, sed affirmativa de praedicato infinito.
He continues the induction with substantive enunciations having a third determinant. The negation of the enunciation “man is white” is “man is not white,” in which the verb is negated. The negation is not “man is non-white,” for this is not the negative, but the affirmative of the infinite predicate.
Peri.L8
Et quia istae duae affirmativae de praedicato finito et infinito non possunt de eodem verificari, propterea quia sunt de praedicatis oppositis, posset aliquis credere quod sint contradictoriae;
Now, it might be thought that the affirmatives of the finite and infinite predicates are contradictories since they cannot be verified of the same thing because of their opposed predicates.
Peri.L8
et ideo ad hunc errorem tollendum interponit rationem probantem quod hae duae non sunt contradictoriae. Est autem ratio talis. Contradictoriorum talis est natura quod de omnibus aut dictio, idest affirmatio aut negatio verificatur. Inter contradictoria siquidem nullum potest inveniri medium; sed hae duae enunciationes, scilicet, est homo albus, et, est homo non albus, sunt contradictoriae per se; ergo sunt talis naturae quod de omnibus altera verificatur. Et sic, cum de ligno sit falsum dicere, est homo albus, erit verum dicere de eo, scilicet ligno, esse non album hominem, idest, lignum est homo non albus. Quod est manifeste falsum: lignum enim neque est homo albus, neque est homo non albus. Restat ergo ex quo utraque est simul falsa de eodem, quod non sit inter eas contradictio. Sed contradictio fit quando negatio apponitur verbo.
To obviate this error, Aristotle interposes an argument proving that these two are not contradictories. The nature of contradictories, he reasons, is such that either the assertion (that is, the affirmation) or the negation is verified of anything, for between contradictories no middle is possible. Now the two enunciations that something is white man and is non-white man are per se contradictories. Therefore, they are of such a nature that one of them is verified of anything. For example, it is false to say “is white man” of wood; hence “is non-white man” will be true to say of it (that is, of wood)—“wood is non-white man.” This is manifestly false, for wood is neither white man nor non-white man. Consequently, there is not a contradiction in the case in which each is at once false of the same subject. Therefore, contradiction is effected when the negation is added to the verb.
Peri.L8
300. Deinde prosequitur inductionem in enunciationibus adiectivi verbi, dicens: quod si hoc modo, scilicet supradicto, accipitur contradictio, et in quantiscunque enunciationibus esse non ponitur explicite, idem faciet quoad oppositionem sumendam, id quod pro esse dicitur (idest verbum adiectivum, quod locum ipsius esse tenet, pro quanto, propter eius veritatem in se inclusam, copulae officium facit), ut eius enunciationis quae est, homo ambulat, negatio est, non ea quae dicit, non homo ambulat (haec enim est affirmativa de subiecto infinito), sed negatio illius est, homo non ambulat; sicut et in illis de verbo substantivo, negatio verbo addenda erat. Nihil enim differt dicere verbo adiectivo, homo ambulat, vel substantivo, homo est ambulans.
He continues his induction with enunciations having an adjective verb: now, if the case is as we have stated it (21a38), that is, if contradiction is taken as said above, then in enunciations in which “to be” is not the determining word added (explicitly), that which is said in place of “to be” will effect the same thing with respect to the opposition obtained—that is, the adjective verb that occupies the place of “to be,” inasmuch as the truth of “to be” is included in it, effects the function of the copula. For example, the negation of the enunciation man walks is not non-man walks (for this is the affirmative of the infinite subject), but man does not walk. In this case, as in that of the substantive verb, the negation must be added to the verb, for there is no difference between using the adjective verb, as in “man walks,” and using the substantive verb, as in “man is walking.”
Peri.L8
301. Deinde ponit secundam partem inductionis dicens: et si hoc modo in omnibus sumenda est contradictio, scilicet, apponendo negationem ad esse, concluditur quod et eius enunciationis, quae dicit, possibile esse, negatio est, possibile non esse, et non illa quae dicit, non possibile esse. Patet conclusionis sequela: quia in illa, possibile non esse, negatio apponitur verbo; in ista autem non. Dixit autem in principio huius rationis: eorum quae complectuntur, idest complexorum, contradictiones fiunt secundum esse et non esse, ad differentiam incomplexorum quorum oppositio non fit negatione dicente non esse, sed ipsi incomplexo apposita, ut, homo, et, non homo, legit, et non legit.
Then he posits the second part of the induction: and if this is always the case (21a38), that is, that contradiction must be gotten by adding the negation to “to be,” we must conclude that the negation of the enunciation that asserts “possible to be” is “possible not to be,” and not “not possible to be.” The consequent of the conclusion is evident, for in “possible not to be” the negation is added to the verb, in “not possible to be,” it is not. At the beginning of this argument, Aristotle said, of those things that are combined, that is, complex things, the contradictions are effected according to “to be” and “not to be.” He said this in reference to the difference between complex and incomplex things, for opposition in the latter is not made by the negation expressing not to be, but by adding the negative to the incomplex thing itself, as in “man” and “non-man,” “reads” and “non-reads.”
Peri.L8
302. Deinde cum dicit: videtur autem idem etc., arguit ad quaestionis partem negativam (scilicet quod ad sumendam contradictionem in modalibus non addenda est negatio verbo), tali ratione. Impossibile est duas contradictorias esse simul veras de eodem; sed supradictae, scilicet, possibile esse, et, possibile non esse, simul verificantur de eodem; ergo istae non sunt contradictoriae: igitur contradictio modalium non attenditur penes verbi negationem.
When he says, however, it seems that the same thing (21b12), he argues for the negative part of the question—namely, that to get a contradiction in modals, the negation should not be added to the verb. His reasoning is the following: It is impossible for two contradictories to be true at once of the same subject; but “possible to be” and “possible not to be” are verified at once of the same thing; therefore, these are not contradictories. Consequently, contradiction of the modals is not obtained by negation of the verb.
Peri.L8
Huius rationis primo ponitur in littera minor cum sua probatione;
In this reasoning, the minor is posited first, with its proof;
Peri.L8
secundo maior;
second, the major;
Peri.L8
tertio conclusio.
third, the conclusion.
Peri.L8
Minor quidem cum dicit: videtur autem idem possibile esse, et, non possibile esse. Sicut verbi gratia, omne quod est possibile dividi est etiam possibile non dividi, et quod est possibile ambulare est etiam possibile non ambulare. Ratio autem huius minoris est, quoniam omne quod sic possibile est (sicut, scilicet, est possibile ambulare et dividi), non semper actu est: non enim semper actualiter ambulat, qui ambulare potest; nec semper actu dividitur, quod dividi potest. Quare inerit etiam negatio possibilis, idest, ergo non solum possibilis est affirmatio, sed etiam negatio eiusdem.
The minor is: however, it seems that the same thing is possible to be and possible not to be (21b12). For instance, everything that has the possibility of being divided also has the possibility of not being divided, and that which has the possibility of walking also has the possibility of not walking. The proof of this minor is that everything that is possible in this way (like “possible to walk” and “to be divided”) is not always in act; for he who is able to walk is not always actually walking, nor is that which can be divided always divided. And so the negation of the possible will also be inherent in it, that is, therefore not only is the affirmation possible but also the negation.
Peri.L8
Adverte quod quia possibile est multiplex, ut infra dicetur, ideo notanter Aristoteles addidit ly sic, assumens, quod sic possibile est, non semper actu est. Non enim de omni possibili verum est dicere quod non semper actu est, sed de aliquo, eo scilicet quod est sic possibile, quemadmodum ambulare et dividi.
Notice that since the possible is manifold, as will be said further on, Aristotle explicitly adds in this way when he assumes here that that which is possible is not always in act. For it is not true to say of every possible thing that it is not always in act, but only of some, namely, those that are possible in the way in which to walk and to be divided are possible.
Peri.L8
Nota ulterius quod quia tale possibile habet duas conditiones, scilicet quod potest actu esse et quod non semper actu est, sequitur necessario quod de eo simul est verum dicere, possibile esse, et, non esse. Ex eo enim quod potest actu esse, sequitur quod sit possibile esse; ex eo vero quod non semper actu est, sequitur quod sit possibile non esse. Quod enim non semper est, potest non esse.
Note also that “possible in this way” has two conditions: that it is able to be in act, and that it is not always in act. It follows necessarily, then, that it is true to say of it simultaneously that it is both possible to be and possible not to be. From the fact that it can be in act it follows that it is possible to be; from the fact that it is not always in act it follows that it is possible not to be, for that which not always is, is able not to be.
Peri.L8
Bene ergo intulit Aristoteles ex his duobus: quare inerit etiam negatio possibilis et non solum affirmatio; potest igitur et non ambulare, quod est ambulabile, et non videri, quod est visibile.
Aristotle, then, rightly infers from these two: and so the negation of the possible will also be inherent in it; and not just the affirmation, for that which could walk could also not walk and that which could be seen not be seen (21b12).
Peri.L8
Maior vero subiungitur, cum ait: at vero impossibile est de eodem veras esse contradictiones.
The major is: but it is impossible that contradictions in respect to the same thing be true (21b12).
Peri.L8
Infertur quoque ultimo conclusio: non est igitur ista (scilicet, possibile non esse) negatio illius, quae dicit, possibile esse: quia sunt simul verae de eodem.
The final conclusion inferred is: therefore, the negation of “possible to be” is not “possible not to be” (21b12), because they are true at once of the same thing.
Peri.L8
Caveto autem ne ex isto textu putes possibile, ut est modus, debere semper accipi pro possibili ad utrumlibet: quoniam hoc infra declarabitur esse falsum; sed considera quod satis fuit intendenti declarare quod in modalibus non sumitur contradictio ex verbi negatione, afferre instantiam in una modali, quae continetur sub modalibus de possibili.
In relation to this part of the text, be careful not to suppose that possible-as-a-mode is always to be taken for possible to either of two alternatives, for this will be shown to be false later on. If you consider the matter carefully, you will see that it was enough for his intention to give as an instance one modal contained under the modals of the possible in order to show that contradiction in modals is not obtained by negation of the verb.
Peri.L8
303. Deinde cum dicit: contingit autem unum ex his etc., determinat veritatem huius dubitationis. Et quia duo petebat, scilicet, an contradictio modalium ex negatione verbi fiat an non, et, an potius ex negatione modi; ideo primo, determinat veritatem primae petitionis, quod scilicet contradictio harum non fit negatione verbi;
Aristotle establishes the truth with respect to this difficulty where he says, for it follows from what we have said (21b19). Since he is investigating two things—namely, whether contradiction of modals is made by the negation of the verb or not, and whether it is not rather by negation of the mode—he first determines the truth in relation to the first question, namely, that contradiction of modals is not made by negation of the verb;
Peri.L8
secundo determinat veritatem secundae petitionis, quod scilicet fiat modalium contradictio ex negatione modi; ibi: est ergo negatio et cetera.
second, he determines the truth in relation to the second, namely, that contradiction of modals is made by negation of the mode, at: therefore, the negation of “possible to be” is “not possible to be" (21b23; [304]).
Peri.L8
Dicit ergo quod propter supradictas rationes evenit unum ex his duobus,
Hence he says that because of the foresaid reasoning one of these two follows:
Peri.L8
quae conclusimus determinare, aut idem ipsum, idest, unum et idem dicere, idest affirmare et negare simul de eodem: idest, aut quod duo contradictoria simul verificantur de eodem, ut prima ratio conclusit;
first, that either the same thing, that is, one and the same thing is said or is asserted and denied at once of the same subject (21b19), that is, either two contradictories are verified at once of the same thing, as the first argument concluded;
Peri.L8
aut affirmationes vel negationes modalium, quae opponuntur contradictorie, fieri non secundum esse vel non esse, idest, aut contradictio modalium non fiat ex negatione verbi, ut secunda ratio conclusit.
or that assertions and denials of modals, which are opposed contradictorily are not made by the addition of “to be” or “not to be” (21b19), that is, contradiction of modals is not made by the negation of the verb, as the second argument concluded.
Peri.L8
Si ergo illud est impossibile, scilicet quod duo contradictoria possunt simul esse vera de eodem, hoc, scilicet quod contradictio modalium non fiat secundum verbi negationem, erit magis eligendum. Impossibilia enim semper vitanda sunt.
If the former alternative is impossible (21b19), namely, that two contradictories can be true of the same thing at once, the latter, that contradiction of modals is not made according to negation of the verb, must obtain, for impossible things must always be avoided.
Peri.L8
Ex ipso autem modo loquendi innuit quod utrique earum aliquid obstat. Sed quia primo obstat impossibilitas quae acceptari non potest, secundo autem nihil aliud obstat nisi quod negatio supra enunciationis copulam cadere debet, si negativa fieri debet enunciatio, et hoc aliter fieri potest quam negando dicti verbum, ut infra declarabitur; ideo hoc secundum, scilicet quod contradictio modalium non fiat secundum negationem verbi, eligendum est: primum vero est omnino abiiciendum.
His mode of speaking here indicates that there is some obstacle to each alternative. But since in the first the obstacle is an impossibility that cannot be accepted, while in the second the only obstacle is that the negation must fall upon the copula of the enunciation if a negative enunciation is to be formed, and this can be done otherwise than by denying the verb of the dictum, as will be shown later on, then the second alternative must be chosen (namely, that the contradiction of modals is not made according to negation of the verb), and the first alternative is to be rejected.
Peri.L8
L. 9 (1.12, 21b23–22a13)In Contradictions of Modal Propositions the Negation Must Be Added to the Modes, Not to the Verb
In Contradictions of Modal Propositions the Negation Must Be Added to the Modes, Not to the Verb
Peri.L9
Est ergo negatio eius quae est, possibile esse, ea quae est non possibile esse. Eadem quoque ratio est et in eo quod est contingens esse: etenim negatio eius est, non contingens esse; et in aliis quoque simili modo, ut innecessario et impossibili.
21b23. Therefore, the negation of “possible to be” is “not possible to be.” The reasoning is the same in regard to “contingent to be,” for its negation is “not contingent to be.” So, too, in the others—that is, the necessary and the impossible.
Peri.L9
Fiunt enim quemadmodum in illis, esse et non esse, appositiones, subiectae vero res, hoc quidem album, illud vero homo: eodem quoque modo hoc in loco, esse quidem et non esse, ut subiectum fit, posse vero et contingere appositiones sunt, determinantes (quemadmodum in illis esse et non esse) veritatem et falsitatem, similiter hae in eo quod est, esse possibile et esse non possibile.
21b26. For just as “to be” and “not to be” are the determining additions in the former [that is, absolute enunciations] and the things subjected are “white” and “man,” so here “to be” is as the subject and “is possible” and “is contingent” are determining additions; and just as “to be” and “not to be” determine the true [and the false] in the former, in like manner these determine the true [and the false] in regard to what is possible and not possible.
Peri.L9
Eius vero, quae est, possibile non esse, negatio est non ea quae est, non esse, sed ea quae est, non possibile; et eius quae est, possibile esse, non ea quae est, possibile non esse, sed ea quae est, non possibile esse. Quare et sequi sese invicem videbuntur, possibile esse et possibile non esse. Idem enim possibile esse et non esse. Non enim contradictiones sunt sibi invicem huiusmodi, possibile esse et possibile non esse; sed possibile esse et non possibile esse, nunquam simul sunt in eodem verae sunt:
21b33. The negation, then, of “possible not to be” is “not possible not to be.” Therefore, “possible to be” and “possible not to be” would appear to be consequent to each other; for the same thing is “possible to be” and “possible not to be,” since these are not contradictory to each other. But “possible to be” and “not possible to be” are never true at once of the same subject, for they are opposed. Nor are “possible not to be” and “not possible not to be” ever true at once of the same subject.
Peri.L9
opponuntur enim neque ea quae est, possibile non esse et non possibile non esse, nunquam simul in eodem verae sunt. Similiter autem et eius quae est, necessarium est, negatio non est quae est, necessarium non esse, sed ea quae est, non necessarium esse; eius vero quae est, necessarium non esse, ea quae est, non necessarium non esse.
The case is the same with respect to the necessary. The negation of “necessary to be” is not, “necessary not to be” but “not necessary to be”; and the negation of “necessary not to be,” “not necessary not to be.”
Peri.L9
Et eius quae est, impossibile esse, non ea quae est, impossibile non esse, sed haec, non impossibile esse; eius vero quae est, impossibile non esse, ea quae est, non impossibile non esse.
Likewise, the negation of “impossible to be” is not “impossible not to be” but “not impossible to be”; and of “impossible not to be,” “not impossible not to be.”
Peri.L9
Universaliter vero, quemadmodum dictum est, esse quidam et non esse oportet ponere quemadmodum subiecta, negationem vero et affirmationem haec facientem, ad esse et non esse apponere. Et has oportet putare esse oppositas dictiones:
22a8. And universally, as has been said, “to be” and “not to be” must be posited as the subject, and those that produce affirmation and negation [that is, possible, not possible, contingent, not contingent, and so on] must be joined to “to be” and “not to be.” And these are the words that are to be considered opposed:
Peri.L9
possibile, non possibile; contingens, non contingens; impossibile, non impossibile; necessarium, non necessarium; verum, non verum.
possible and not possible; contingent and not contingent; impossible and not impossible; necessary and not necessary; true and not true.
Peri.L9
304. Determinat ubi ponenda sit negatio ad assumendam modalium contradictionem.
Aristotle now determines where the negation must be placed in order to obtain contradiction in modals.
Peri.L9
Et circa hoc quatuor facit:
About this he does four things.
Peri.L9
primo, determinat veritatem summarie;
He first determines the truth summarily;
Peri.L9
secundo, assignat determinatae veritatis rationem, quae dicitur rationi ad oppositum inductae; ibi: fiunt enim etc.;
second, he presents the argument for the truth of the position, which is also the answer to the reasoning induced for the opposite position, at: for just as “to be” and “not to be” (21b26; [305]);
Peri.L9
tertio, explanat eamdem veritatem in omnibus modalibus; ibi: eius vero etc.;
third, he makes this truth evident in all the modals, at: the negation, then, of “possible not to be” is “not possible not to be” (21b33; [307]);
Peri.L9
quarto, universalem regulam concludit; ibi: universaliter vero et cetera.
fourth, he arrives at a universal rule, at: and universally, as has been said, “to be” and “not to be” (22a8; [308]).
Peri.L9
Quia igitur negatio aut verbo aut modo apponenda est, et quod verbo non addenda est, declaratum est per locum a divisione; concludendo determinat: est ergo negatio eius quae est possibile esse, ea quae est non possibile esse, in qua negatur modus. Et eadem est ratio in enunciationibus de contingenti. Huius enim, quae est, contingens esse, negatio est, non contingens esse. Et in aliis, scilicet de necesse et impossibile idem est iudicium.
Since the negation must be added either to the verb or to the mode, and it was shown above in virtue of an argument from division that it is not to be added to the verb, he concludes: therefore, the negation of “possible to be” is “not possible to be” (21b23), that is, the mode is negated. The reasoning is the same with respect to enunciations of the contingent, for the negation of “contingent to be” is “not contingent to be.” And the judgment is the same in the others, namely, the necessary and the impossible.
Peri.L9
305. Deinde cum dicit: fiunt enim in illis appositiones etc., subdit huius veritatis rationem talem. Ad sumendam contradictionem inter aliquas enunciationes oportet ponere negationem super appositione, idest coniunctione praedicati cum subiecto; sed in modalibus appositiones sunt modi; ergo in modalibus negatio apponenda est modo, ut fiat contradictio. Huius rationis, maiore subintellecta, minor ponitur in littera per secundam similitudinem ad illas de inesse. Et dicitur quod quemadmodum in illis enunciationibus de inesse appositiones, idest praedicationes, sunt esse et non esse, idest verba significativa esse vel non esse (verbum enim semper est nota eorum quae de altero praedicantur), subiective vero appositionibus res sunt, quibus esse vel non esse apponitur, ut album, cum dicitur, album est, vel homo, cum dicitur, homo est; eodem modo hoc in loco in modalibus accidit: esse quidem subiectum fit, idest dictum significans esse vel non esse subiecti locum tenet; contingere vero et posse oppositiones, idest modi, praedicationes sunt. Et quemadmodum in illis de inesse penes esse et non esse veritatem vel falsitatem determinavimus, ita in istis modalibus penes modos. Hoc est enim quod subdit, determinantes, scilicet, fiunt ipsi modi veritatem, quemadmodum in illis esse et non esse, eam determinat.
When he says, for just as “to be” and “not to be” are the determining additions (21b26), he gives the argument for the truth of his position. To obtain contradiction among any enunciations the negation must be applied to the determining addition, that is, to the word that joins the predicate with the subject; but in modals the determining additions are the modes; therefore, to get a contradiction in modals, the negation must be added to the mode. The major of the argument is subsumed; the minor is stated in Aristotle’s wording by a further similitude to absolute enunciations. In absolute enunciations the determining additions, namely, the predications, are “to be” and “not to be,” that is, the verb signifying “to be” or “not to be” (for the verb is always a sign of those things that are predicated of another). The things subjected to the determining additions, that is, to which “to be” and “not to be” are applied, are “white,” in “white is, “or man,” in “man is.” This happens in modals in the same way but in a manner appropriate to them. “To be” is as the subject, that is, the dictum signifying “to be” or “not to be” holds the place of the subject; “is possible” and “is contingent,” that is, the modes, are the predicates. And just as in absolute enunciations we determine truth or falsity with “to be” and “not to be,” so in modals with the modes. He makes this point when he says, determining additions, that is, these modes effect truth just as “to be” and “not to be” determine truth and falsity in the others.
Peri.L9
306. Et sic patet responsio ad argumentum in oppositum primo adductum, concludens quod negatio verbo apponenda sit, sicut illis de inesse. Dicitur enim quod cum modalis enunciet modum de dicto sicut enunciatio de inesse, esse vel esse tale, puta esse album de subiecto, eumdem locum tenet modus hic, quem ibi verbum; et consequenter super idem proportionaliter cadit negatio hic et ibi. Eadem enim, ut dictum est, proportio est modi ad dictum, quae est verbi ad subiectum.
Thus the response to the argument for the opposite position, which he gave first, is evident. That argument concluded that the negation should be added to the verb as it is in absolute enunciations. But since the modal enunciates a mode of a dictum—as the absolute enunciation enunciates “to be” or “not to be” (as, for instance, “to be white” of a subject)—the mode holds the same place here that the verb does there. Consequently, the negation falls upon the same thing proportionally here and there, for the proportion of mode to dictum is the same as the proportion of verb to subject.
Peri.L9
Rursus cum veritas et falsitas affirmationem et negationem sequantur, penes idem attendenda est affirmatio vel negatio enunciationis, et veritas vel falsitas eiusdem; sicut autem in enunciationibus de inesse veritas vel falsitas esse vel non esse consequitur, ita in modalibus modum. Illa namque modalis est vera quae sic modificat dictum sicut dicti compositio patitur, sicut illa de inesse est vera, quae sic significat esse sicut est. Est ergo negatio modo hic apponenda, sicut ibi verbo, cum sit eadem utriusque vis quoad veritatem et falsitatem enunciationis.
Again, since truth and falsity follow upon affirmation and negation, the affirmation and negation of an enunciation and its truth and falsity must be controlled by the same thing. In absolute enunciations truth and falsity follow upon “to be” or “not to be”; hence in the modals they follow upon the mode, for that modal is true which modifies the dictum as the composition of the dictum permits, just as that absolute enunciation is true which signifies that something is as it is. Therefore, negation is added here to the mode just as it is added there to the verb, since the power of each is the same with respect to the truth and falsity of an enunciation.
Peri.L9
Adverte quod modos, appositiones, idest, praedicationes vocavit, sicut esse in illis de inesse, intelligens per modum totum praedicatum enunciationis modalis, puta, est possibile. In cuius signum modos ipsos verbaliter protulit dicens: contingere vero et posse appositiones sunt. Contingit enim et potest, totum praedicatum modalis continent.
Notice that he calls the modes “determining additions,” that is, predications, as “to be” is in absolute enunciations—understanding by the mode the whole predicate of the modal enunciation, for example, “is possible.” As a sign of this, he expresses the modes themselves verbally when he says, “is possible” and “is contingent” are determining additions. For is contingent and is possible comprise the whole predicate of the modal enunciation.
Peri.L9
307. Deinde cum dicit: eius vero quod est possibile est non esse etc., explanat determinatam veritatem in omnibus modalibus, scilicet de possibili, et necessario, et impossibili. Contingens convertitur cum possibili. Et quia quilibet modus facit duas modales affirmativas, alteram habentem dictum affirmatum, et alteram habentem dictum negatum; ideo explanat in singulis modis quae cuiusque affirmationis negatio sit.
When he says, the negation, then, of “possible not to be” (21b33), he makes this truth evident in all the modals, namely, the possible, the necessary, and the impossible (the contingent being convertible with the possible). And since any mode makes two modal affirmatives, one having an affirmed dictum and the other having a negated dictum, he shows what the negation of each affirmation is in each mode.
Peri.L9
Et primo in illis de possibili. Et quia primae affirmativae de possibili (quae scilicet habet dictum affirmatum) scilicet possibile esse, negatio assignata fuit, non possibile esse; ideo ad reliquam affirmativam de possibili transiens ait: eius vero, quae est possibile non esse (ubi dictum negatur) negatio est non possibile non esse. Et hoc consequenter probat per hoc quod contradictoria huius, possibile non esse, aut est, possibile esse, aut illa, quam diximus, scilicet, non possibile non esse. Sed illa, scilicet, possibile esse, non est eius contradictoria. Non enim sunt sibi invicem contradicentes, possibile esse, et, possibile non esse, quia possunt simul esse verae. Unde et sequi sese invicem putabuntur: quoniam, ut supra dictum fuit, idem est, possibile esse, et, non esse, et consequenter sicut ad, posse esse, sequitur, posse non esse, ita e contra ad, posse non esse, sequitur, posse esse; sed contradictoria illius, possibile esse, quae non potest simul esse vera est, non possibile esse: hae enim, ut dictum est, opponuntur. Remanet ergo quod huius negatio, possibile non esse, sit illa, non possibile non esse: hae namque simul nunquam sunt verae vel falsae.
First, he takes those of the possible. The negation of the first affirmative of the possible (the one with an affirmed dictum)—namely, “possible to be”—was assigned as “not possible to be.” Hence, going on to the remaining affirmative of the possible, he says, the negation, then, of “possible not to be” (in which the dictum is negated) is “not possible not to be.” Then he proves this. The contradictory of “possible not to be” is either “possible to be” or “not possible not to be.” But the former, “possible to be,” is not the contradictory of “possible not to be,” for they can be at once true. Hence they are also thought to follow upon each other, for, as was said above, the same thing is possible to be and not to be. Consequently, just as “possible not to be” follows upon “possible to be,” so conversely “possible to be” follows upon “possible not to be.” But the contradictory of “possible to be,” which cannot be true at the same time, is “not possible to be,” for these, as has been said, are opposed. Therefore, the negation of “possible not to be” is “not possible not to be,” for these are never at once true or false.
Peri.L9
Dixit quod possibile esse et non esse sequi se invicem putabuntur, et non dixit quod se invicem consequuntur: quia secundum veritatem universaliter non sequuntur se, sed particulariter tantum, ut infra dicetur; propter quod putabitur quod simpliciter se invicem sequantur.
Note that he says, therefore, “possible to be” and “possible not to be” would appear to be consequent to each other, and not that they do follow upon each other, for it is not true that they follow upon each other universally, but only particularly (as will be said later); this is the reason they appear to follow upon each other simply.
Peri.L9
Deinde declarat hoc idem in illis de necessario.
Then he manifests the same thing in the modals of the necessary.
Peri.L9
Et primo, in affirmativa habente dictum affirmatum, dicens: similiter eius quae est, necessarium esse, negatio non est ea, quae dicit necessarium non esse, ubi modus non negatur, sed ea quae est, non necessarium esse.
first, in the affirmative with an affirmed dictum: the case is the same with respect to the necessary. The negation of “necessary to be” is not “necessary not to be” (in which the mode is not negated) but, “not necessary to be.”
Peri.L9
Deinde subdit de affirmativa de necessario habente dictum negatum, et ait: eius vero, quae est, necessarium non esse, negatio est ea, quae dicit, non necessarium non esse.
Next, he adds the affirmative of the necessary with a negated dictum: and the negation of “necessary not to be is “not necessary not to be.”
Peri.L9
Deinde transit ad illas de impossibili, eumdem ordinem servans, et inquit: et eius, quae dicit, impossibile esse, negatio non est ea quae dicit, impossibile non esse, sed, non impossibile esse: ubi iam modus negatur. Alterius vero affirmativae, quae est, impossibile non esse, negatio est ea quae dicit non impossibile non esse. Et sic semper modo negatio addenda est.
Next, he takes up the impossible, keeping the same order. The negation of “impossible to be” is not “impossible not to be” but, “not impossible to be,” in which the mode is negated. The negation of the other affirmative, “impossible not to be,” is “not impossible not to be.” The negation, therefore, is always added to the mode.
Peri.L9
308. Deinde cum dicit: universaliter vero etc., concludit regulam universalem dicens quod, quemadmodum dictum est, dicta importantia esse et non esse oportet ponere in modalibus ut subiecta, negationem vero et affirmationem hoc, idest contradictionis oppositionem, facientem, oportet apponere tantummodo ad suum eumdem modum, non ad diversos modos. Debet namque illemet modus negari, qui prius affirmabatur, si contradictio esse debet.
Then he says, and universally, as has been said (22a8). Here he concludes with the universal rule. As has been said, the dictums denoting “to be” and “not to be” must be posited in the modals as subjects, and the one making this an affirmation and negation—that is, the opposition of contradiction—must be added only to the selfsame mode, not to diverse modes, for the selfsame mode which was previously affirmed must be denied if there is to be a contradiction.
Peri.L9
Et exemplariter explanans quomodo hoc fiat, subdit: et oportet putare has esse oppositas dictiones, idest affirmationes et negationes in modalibus, possibile et non possibile, contingens et non contingens. Item cum dixit negationem alio tantum modo ad modum apponi debere, non exclusit modi copulam, sed dictum. Hoc enim est singulare in modalibus quod eamdem oppositionem facit, negatio modo addita, et eius verbo. Contradictorie enim opponitur huic, possibile est esse, non solum illa, non possibile est esse, sed ista, possibile non est esse;
He gives examples of how this is to be done when he adds, and these are the words that are to be considered opposed, that is. affirmations and negations in modals, possible and not possible, contingent and not contingent. Moreover, when he said elsewhere but in another way that the negation must be applied only to the mode, he did not exclude the copula of the mode, but the copula of the dictum. For it is unique to modals that the same opposition is made by adding a negation to the mode and to its verb. The contradictory of “is possible to be,” for instance, is not only “is not possible to be,” but also “not is possible to be.”
Peri.L9
meminit autem modi potius, et propter hoc quod nunc diximus,
There are two reasons, however, for his mentioning the mode rather than the verb:
Peri.L9
ut scilicet insinuaret quod negatio verbo modi postposita, modo autem praeposita, idem facit ac si modali verbo praeponeretur,
first, for the reason we have just given, namely, so as to imply that the negation placed after the verb of the mode, the mode having been put first, accomplishes the same thing as if it were placed before the modal verb;
Peri.L9
et quia, cum modo numquam caret modalis enunciatio, semper negatio supra modum poni potest. Non autem sic de eius verbo: verbo enim modi carere contingit modalem, ut cum dicitur, Socrates currit necessario; et ideo semper verbo negatio aptari potest.
second, because the modal enunciation is never without a mode; hence the negation can always be put on the mode. However, it cannot always be put on the verb of a mode, for the modal enunciation may lack the verb of a mode—as, for example, in “Socrates runs necessarily,” in which case the negation can always be adapted to the verb.
Peri.L9
Quod autem in fine addidit, verum et non verum, insinuat, praeter quatuor praedictos modos, alios inveniri, qui etiam compositionem enunciationis determinant, puta, verum et non verum, falsum et non falsum: quos tamen inter modos supra non posuit, quia, ut declaratum fuit, non proprie modificant.
In adding true and not true at the end, he implies that besides the four modes mentioned previously there are others that also determine the composition of the enunciation, for example, “true” and “not true,” “false” and “not false.” Nevertheless, he did not posit these among the modes first given because, as was shown, they do not properly modify.
Peri.L9
L. 10 (1.13, 22a14–22b28)The Logical Consequents of the Modals
The Logical Consequents of the Modals
Peri.L10
Consequentiae vero secundum rationem fiunt cum ita ponuntur illam enim quae est, possibile esse, sequitur illa quae est, contingit esse, et haec illi convertitur, et, non impossibile esse et non necessarium esse; illam vero quae est, possibile non esse, et, contingens non esse, ea quae est, non necesse non esse, et, non impossibile non esse: illam autem quae est, non possibile esse, et, non contingens esse, ea quae est, necessarium non esse, et impossibile esse: illam vero quae est, non possibile non esse, et, non contingens non esse, ea quae est, necesse est esse, et, impossibile non esse. Consideretur autem ex subscriptione quemadmodum dicimus:
22a14. Logical sequences result from modals ordered thus. From “possible to be” follows “contingent to be,” and the latter is convertible with the former; “not impossible to be” and “not necessary to be” also follow from “possible to be.” From “possible not to be” follows “contingent not to be,” “not necessary not to be,” and “not impossible not to be.” From “not possible to be” and “not contingent to be” follows “necessary not to be” and “impossible to be.” From “not possible not to be” and “not contingent not to be” follows “necessary to be” and “impossible not to be.” Let us consider these with the help of a table.
Peri.L10
Possibile est esse, non possibile est esse.
22a24. Possible to be—not possible to be
Peri.L10
Contingens est esse, non contingens est esse.
contingent to be—not contingent to be
Peri.L10
Non impossibile est esse, impossibile est esse.
not impossible to be—impossible to be
Peri.L10
Non necessarium est esse, necessarium est non esse.
not necessary to be—necessary not to be
Peri.L10
Possibile est non esse, non possibile est non esse.
possible not to be—not possible not to be
Peri.L10
Contingens est non esse, non contingens est non esse.
contingent not to be—not contingent not to be
Peri.L10
Non impossibile est non esse, impossibile est non esse.
not impossible not to be—impossible not to be
Peri.L10
Non necessarium est non esse, necessarium est esse.
not necessary not to be—necessary to be
Peri.L10
Hae igitur, impossibile, et, non impossibile, eam quae est, contingens, et possibile, et non contingens, et non possibile sequuntur quidem contradictorie, sed conversim. Eam enim quae est, possibile esse, negatio impossibilis sequitur, quae est, non impossibile esse: negationem vero affirmatio. Illam enim, non possibile esse, ea quae est, impossibile esse: affirmatio enim est, impossibile esse; non impossibile vero, negatio.
22a32. Now, the impossible and the not impossible follow contradictorily upon the contingent and the possible and the not contingent and the not possible, but inversely. The negation of “impossible to be” follows upon “possible to be,” and the affirmation of the former follows upon the negation of the latter, that is, “impossible to be” follows upon “not possible to be.” For “impossible to be” is an affirmation, “not impossible to be” a negation.
Peri.L10
Necessarium autem quemadmodum se habeat, considerandum est. Manifestum est autem quod non eodem modo se habet, sed contrariae sequuntur, contradictoriae autem sunt extra.
22a38. Now, we must consider how enunciations predicating necessity are related to these. It is evident that the case here is not the same, for the contraries follow, but their contradictories are separated.
Peri.L10
Non enim est negatio eius, quae est, necesse non esse, ea quae est, non necesse esse: contingit enim veras esse utrasque in eodem: quod enim est necessarium non esse, non est necessarium esse.
22a39. For the negation of “necessary not to be” is not “not necessary to be,” since both may be true of the same subject, for the necessary not to be is not necessary to be.
Peri.L10
Causa autem huius est, cur non sequitur necessarium caeteris similiter: quoniam contrarie, impossibile esse, necessario redditur idem valens. Nam quod impossibile esse, necesse hoc non quidem esse, sed potius non esse: quod vero impossibile non esse, hoc necessarium esse. Quare si illa similiter sequuntur possibile, et, non possibile: haec ex opposito: quoniam non significant idem necessarium et impossibile; sed (ut dictum est) conversim.
22b3. Now, the reason why enunciations predicating necessity do not follow in the same way as the others is that the impossible expresses contrarily the same thing as the necessary. For if it is impossible that this be, it is necessary, not that it be, but necessary that it not be; and if it is impossible that it not be, it is necessary that it be. So, if the impossible and not impossible follow in like manner from the possible and not possible, the necessary and not necessary follow contrarily, since the necessary and the impossible signify the same thing, but (as has been said) inversely.
Peri.L10
Aut certe impossibile est sic poni necessarii contradictiones. Nam quod necessarium est esse, possibile est esse: nam si non, negatio consequetur: necesse est enim aut affirmare, aut negare. Quare si non possibile est esse, impossibile est esse. Igitur impossibile est esse quod necesse est esse: quod est inconveniens. At vero illam quae est, possibile esse, non impossibile esse, sequitur: hanc vero, ea quae est, non necessarium est esse; quare contingit quod necessarium esse, non necessarium esse: quod est inconveniens.
22b10. Or is it impossible to arrange the contradictions of enunciations predicating necessity in this way? For what is necessary to be, is possible to be (for if not, the negation will follow, since it is necessary either to affirm or deny; and if it is not possible to be, it is impossible to be; therefore, that which is necessary to be is impossible to be, which is absurd). But from “possible to be” follows “not impossible to be,” and from this, “not necessary to be”; and thus what is necessary to be is not necessary to be, which is absurd.
Peri.L10
At vero neque necessarium esse, sequitur eam quae est, possibile esse, neque ea quae est, necessarium non esse. Illi enim utraque contingit accidere: harum autem utralibet vera fuerit, non erunt illa vera: simul enim possibile esse, et, non esse. Si vero necesse esse, vel non esse, non erit possibile utrumque. Relinquitur ergo non necessarium non esse, sequi eam quae est, possibile est esse.
22b17. But, in fact, neither “necessary to be” nor “necessary not to be” follow upon “possible to be.” For “to be possible” admits of two possibilities; but if either “necessary to be” or “necessary not to be” is true, both possibilities will no longer be true. For a thing is at once possible to be and not to be, but if it is necessary to be or not to be, the two alternatives will not be possible. It remains, therefore, that “not necessary not to be” follows upon “possible to be.”
Peri.L10
Haec enim vera est, et de necesse esse. Haec enim fit contradictio eius, quae sequitur illam quae est, non possibile esse: illam enim sequitur ea quae est, impossibile esse, et, necesse non esse, cuius negatio est, non necesse non esse.
22b23. For this is true also with respect to “necessary to be.” For “not necessary not to be” is the contradictory of what follows upon “not possible to be,” for “not possible to be” is followed by “impossible to be” and by “necessary not to be,” and the negation of this is “not necessary not to be.”
Peri.L10
Sequuntur igitur et hae contradictiones secundum praedictum modum: et nihil impossibile contingit sic positis.
22b26. Thus, these contradictions also follow in the way indicated, and nothing impossible follows when they are thus arranged.
Peri.L10
309. Postquam determinavit de oppositione modalium, hic determinare intendit de consequentiis earum.
Having established the opposition of modals, Aristotle now intends to determine their consequents.
Peri.L10
Et circa hoc duo facit:
About this he does two things.
Peri.L10
primo, tradit veritatem;
First, he presents the true doctrine;
Peri.L10
secundo, movet quandam dubitationem circa determinata; ibi: dubitabit autem et cetera.
second, he raises a difficulty, at: but it may be asked (22b29; [327]).
Peri.L10
Circa primum duo facit:
About the first he does two things.
Peri.L10
primo, ponit consequentias earum secundum opinionem aliorum;
First, he posits the consequents of the opposition of modals according to the opinion of others;
Peri.L10
secundo, examinando et corrigendo dictam opinionem, determinat veritatem; ibi: ergo impossibile et cetera.
second, he determines the truth by examining and correcting their opinion, at: now the impossible and the not impossible (22a32; [313]).
Peri.L10
310. Quoad primum considerandum est quod cum quilibet modus faciat duas affirmationes, ut dictum fuit, et duabus affirmationibus opponantur duae negationes, ut etiam dictum fuit in primo; secundum quemlibet modum fient quatuor enunciationes, duae scilicet affirmativae et duae negativae. Cum autem modi sint quatuor, efficientur sexdecim modales: quaternarius enim in seipsum ductus sexdecim constituit. Et quoniam apud omnes, quaelibet cuiusque modi, undecumque incipias, habet unam tantum cuiusque modi se consequentem, ideo ad assignandas consequentias modalium, singulas ex singulis modis accipere oportet et ad consequentiae ordinem inter se adunare.
Before we consider these consequents according to the opinion of others, we must first note that since any mode makes two affirmations to which are opposed two negations, there will be four enunciations according to any one mode, two affirmatives and two negatives. And since there are four modes, there will be sixteen modals. Among these sixteen, from wherever you begin, any one of each mode has only one of each mode following upon it. Hence, to assign the consequents of the modals, we have to take one from each mode and arrange them among themselves to form an order of consequents.
Peri.L10
311. Et hoc modo fecerunt antiqui, de quibus inquit Aristoteles: consequentiae vero fiunt secundum infrascriptum ordinem, antiquis ita ponentibus. Formaverunt enim quatuor ordines modalium, in quorum quolibet omnes quae se consequuntur collocaverunt. Ut autem confusio vitetur, vocetur, cum Averroe, de caetero, in quolibet modo, affirmativa de dicto, et modo, affirmativa simplex; affirmativa autem de modo et negativa de dicto, affirmativa declinata; negativa vero de modo et non dicto, negativa simplex; negativa autem de utroque, negativa declinata: ita quod modi affirmationem vel negationem simplicitas, dicti vero declinatio denominet.
The modals were ordered in this way by the ancients. They disposed them in four orders placing together in each order those that were a consequent to each other. Aristotle speaks of this order when he says, logical sequences follow according to the order in the table below, which is the way in which the ancients posited them (22a14). Henceforth, however, to avoid confusion let us call the affirmative of dictum and mode in any one mode, the simple affirmative, as it is by Averroes, among others; affirmative of mode and negative of dictum, the declined affirmative; negative of mode and not of dictum, the simple negative; negative of both mode and dictum, the declined negative. Hence, simplicity of mode designates affirmation or negation, and so, too, does declination of dictum.
Peri.L10
Dixerunt ergo antiqui quod affirmationem simplicem de possibili, scilicet, possibile est esse, sequitur affirmativa simplex de contingenti, scilicet, contingens est esse (contingens enim convertitur cum possibili); et negativa simplex de impossibili, scilicet, non impossibile esse; et similiter negativa simplex de necessario, scilicet, non necesse est esse. Et hic est primus ordo modalium consequentium se.
The ancients said, then, that simple affirmation of the contingent (that is, “contingent to be”) follows upon simple affirmation of the possible (that is, “possible to be”), for the contingent is converted with the possible; the simple negative of the impossible also follows upon this (namely, “not impossible to be”); and the simple negative of the necessary (namely, “not necessary to be”). This is the first order of modal consequents.
Peri.L10
In secundo autem dixerunt quod affirmativas declinatas de possibili et contingenti, scilicet, possibile non esse, et, contingens non esse, sequuntur negativae declinatae de necessario et impossibili, scilicet, non necessarium non esse, et, non impossibile non esse.
In the second order they said that the declined negatives of the necessary and impossible (namely, “not necessary not to be” and “not impossible not to be”) follow upon the declined affirmative of the possible and the contingent (namely, “possible not to be” and “contingent not to be”).
Peri.L10
In tertio vero ordine dixerunt quod negativas simplices de possibili et contingenti, scilicet, non possibile esse, non contingens esse, sequuntur affirmativa declinata de necessario, scilicet, necesse non esse, et affirmativa simplex de impossibili, scilicet, impossibile esse.
In the third order, according to them, the declined affirmative of the necessary (that is, “necessary not to be”) and the simple affirmative of of the impossible (that is, “impossible to be”) follow upon the simple negatives of the possible and the contingent (that is, “not possible to be” and not contingent to be”).
Peri.L10
In quarto demum ordine dixerunt quod negativas declinatas de possibili et contingenti, scilicet, non possibile non esse, et, non contingens non esse, sequuntur affirmativa simplex de necessario, scilicet, necesse esse, et affirmativa declinata de impossibili, scilicet, impossibile est non esse.
Finally, in the fourth order, the simple affirmative of the necessary (namely, “necessary to be”) and the declined affirmative of the impossible (namely, “impossible not to be”) follow upon the declined negatives of the possible and the contingent (namely, “not possible not to be” and “not contingent not to be”).
Peri.L10
312. Consideretur autem ex subscriptione appositae figurae, quemadmodum dicimus, ut clarius elucescat depictum. Consequentiae enunciationum modalium secundum quatuor ordines ab antiquis positae et ordinatae. (Figura).
To make this ordering more evident, let us consider it with the help of the following table of the consequents of modal enunciations in the four orders posited and ordered by the ancient.
Peri.L10
FIRST ORDERIt is possible to beIt is contingent to beIt is not impossible to beIt is not necessary to be
Peri.L10
SECOND ORDERIt is possible not to beIt is contingent not to beIt is not impossible not to beIt is not necessary not to be
Peri.L10
THIRD ORDERIt is not possible to beIt is not contingent to beIt is impossible to beIt is necessary not to be
Peri.L10
FOURTH ORDERIt is not possible not to beIt is not contingent not to beIt is impossible not to beIt is necessary to be
Peri.L10
313. Deinde cum dicit: ergo impossibile et non impossibile etc., examinando dictam opinionem, determinat veritatem.
When he says, now, the impossible and the not impossible follow contradictorily (22a32), he determines the truth by examining the foresaid opinion.
Peri.L10
Et circa hoc duo facit:
About this he does two things.
Peri.L10
quia primo examinat consequentias earum de impossibili;
First, he examines the consequents of enunciations predicating impossibility;
Peri.L10
secundo, illarum de necessario; ibi: necessarium autem et cetera.
second, those predicating necessity, at: now we must consider how enunciations predicating necessity (22a38; [314]).
Peri.L10
Unde ex praemissa opinione concludens et approbans, dicit: ergo istae, scilicet, impossibile, et, non impossibile, sequuntur illas, scilicet, contingens et possibile, non contingens, et, non possibile, sequuntur, inquam, contradictorie, idest ita ut contradictoriae de impossibili contradictorias de possibili et contingenti consequantur, sed conversim, idest, sed non ita quod affirmatio affirmationem et negatio negationem sequatur, sed conversim, scilicet, quod affirmationem negatio et negationem affirmatio.
From the opinion advanced, then, he concludes with approval that these, the impossible and the not impossible, follow upon the contingent and the possible and the not contingent and the not possible, contradictorily (that is, the contradictories of the impossible follow upon the contradictories of the possible and the contingent), but inversely—that is, not so that affirmation follows upon affirmation and negation upon negation, but inversely, so that negation follows upon affirmation and affirmation upon negation.
Peri.L10
Et explanans hoc ait: illud enim quod est possibile esse, idest affirmationem possibilis negatio sequitur impossibilis, idest, non impossibile esse; negationem vero possibilis affirmatio sequitur impossibilis. Illud enim quod est, non possibile esse, sequitur ista, impossibile est esse; haec autem, scilicet, impossibile esse, affirmatio est; illa vero, scilicet, non possibile esse, negatio est: hic siquidem modus negatur; ibi, non.
He explains this when he says, the negation of “impossible to be” follows upon “possible to be” (22a32), that is, the negation of the impossible (“not impossible to be”) follows upon the affirmation of the possible, and the affirmation of the impossible follows upon the negation of the possible. For the affirmation “impossible to be” follows upon the negation “not possible to be.” In the latter the mode is negated, in the former it is not.
Peri.L10
Bene igitur dixerunt antiqui in quolibet ordine quoad consequentias illarum de impossibili, quia, ut in suprascripta figura apparet, semper ex affirmatione possibilis negationem impossibilis, et ex negatione possibilis affirmationem impossibilis inferunt.
Therefore, the ancients were right in saying that in any order, the consequences of enunciations predicating impossibility are as follows: from affirmation of the possible, negation of the impossible is inferred; and from negation of the possible, affirmation of the impossible is inferred. This is apparent in the diagram.
Peri.L10
314. Deinde cum dicit: necessarium autem etc., intendit examinando determinare consequentias de necessario.
When he says, now, we must consider how enunciations predicating necessity (22a38), he proposes an examination of the consequents of enunciations predicating necessity in order to determine the truth about them.
Peri.L10
Et circa hoc duo facit:
About this he does two things.
Peri.L10
primo examinat dicta antiquorum;
First, he examines what was said by the ancients;
Peri.L10
secundo, determinat veritatem intentam; ibi: at vero neque necessarium et cetera.
second, he determines the truth, at: but in fact neither “necessary to be” nor “necessary not to be” (22b17; [321]).
Peri.L10
Circa primum quatuor facit.
About the first he does four things.
Peri.L10
Primo, declarat quid bene et quid male dictum sit ab antiquis in hac re. Ubi attendendum est quod cum quatuor sint enunciationes de necessario, ut dictum est, differentes inter se secundum quantitatem et qualitatem, adeo ut unam integrent figuram oppositionis iuxta morem illarum de inesse; duae earum sunt contrariae inter se, duae autem illis contrariis contradictoriae, ut patet in hac figura. (Figura).
First, he shows what was well said by the ancients and what was badly said. It must be noted in regard to this that, as we have said, there are four enunciations predicating necessity, which differ among themselves in quantity and quality, and thus make up a diagram of opposition in the manner of the absolute enunciations. Two of them are contrary to each other, and two are contradictory to these contraries, as is clear in the diagram below. [figure]
Peri.L10
Quia ergo antiqui universales contrarias bene intulerunt ex aliis, contradictorias autem earum, scilicet particulares, male intulerunt; ideo dicit quod considerandum restat de his, quae sunt de necessario, qualiter se habeant in consequendo illas de possibili et non possibili. Manifestum est autem ex dicendis quod non eodem modo istae de necessario illas de possibili consequuntur, quo easdem sequuntur illae de impossibili. Nam omnes enunciationes de impossibili recte illatae sunt ab antiquis. Enunciationes autem de necessario non omnes recte inferuntur: sed duae earum, quae sunt contrariae, scilicet, necesse est esse, et, necesse est non esse, sequuntur, idest recta consequentia deducuntur ab antiquis, in tertio scilicet et quarto ordine; reliquae autem duae de necessario, scilicet, non necesse non esse, et, non necesse esse, quae sunt contradictoriae supradictis, sunt extra consequentias illarum, in secundo scilicet et primo ordine. Unde antiqui in tertio et quarto ordine omnia recte fecerunt; in primo autem et in secundo peccaverunt, non quoad omnia, sed quoad enunciationes de necessario tantum.
Now the ancients correctly inferred the universal contraries from the possibles, contingents, and impossibles, but incorrectly inferred their contradictories, namely, particulars. This is the reason Aristotle says that it remains to be considered how enunciations predicating necessity are related consequentially to the possible and not possible. From what Aristotle says, it is clear that those predicating necessity do not follow upon the possibles in the same way as those predicating impossibility follow upon the possibles, for all of the enunciations predicating impossibility were correctly inferred by the ancients, but those predicating necessity were not. Two of them, the contraries “necessary to be” and “necessary not to be,” follow (that is, correct consequents were deduced by the ancients in the third and fourth orders); the remaining two, “not necessary not to be” and “not necessary to be,” which are contradictories of the contraries, are outside of the consequents of these, in the second and first orders. Hence, the ancients represented everything correctly in the third and fourth orders, but in the first and second they erred—though not with respect to all things, but only with respect to enunciations predicating necessity.
Peri.L10
315. Secundo cum dicit: non enim est negatio eius etc., respondet cuidam tacitae obiectioni, qua defendi posset consequentia enunciationis de necessario in primo ordine ab antiquis facta. Est autem obiectio tacita talis. Non possibile esse, et, necesse non esse, convertibiliter se sequuntur in tertio ordine iam approbato; ergo, possibile esse, et, non necesse esse, invicem se sequi debent in primo ordine. Tenet consequentia: quia duorum convertibiliter se sequentium contradictoria mutuo se sequuntur; sed illae duae tertii ordinis convertibiliter se sequuntur, et istae duae primi ordinis sunt earum contradictoriae; ergo istae primi ordinis, scilicet, possibile esse, et, non necesse esse, mutuo se sequuntur.
Second, when he says, for the negation of “necessary not to be” is not “not necessary to be” (22a39), he replies to a tacit objection. This reply could be used to defend the consequent of the enunciation of the necessary made by the ancients in the first order. The tacit objection is this: “not possible to be” and “necessary not to be” follow convertibly in the third order which has already been shown to be correct; therefore, “possible to be” and “not necessary to be” ought to follow upon each other in the first order. The consequent holds, for the contradictories of two that convertibly follow upon each other mutually follow upon each other; but those two follow upon each other convertibly in the third order, and these two in the first order are their contradictories; therefore, those of the first order (namely, “possible to be” and “not necessary to be”) mutually follow upon each other.
Peri.L10
Huic, inquam, obiectioni respondet Aristoteles hic interimendo minorem quoad hoc quod assumit, quod scilicet necessaria primi ordinis et necessaria tertii ordinis sunt contradictoriae. Unde dicit: non enim est negatio eius quod est, necesse non esse (quae erat in tertio ordine), illa quae dicit, non necesse est esse, quae sita erat in primo ordine. Et causam subdit, quia contingit utrasque simul esse veras in eodem; quod contradictoriis repugnat. Illud enim idem, quod est necessarium non esse, non est necessarium esse. Necessarium siquidem est hominem non esse lignum et non necessarium est hominem esse lignum. Adverte quod, ut infra patebit, istae duae de necessario, quas posuerunt antiqui in primo et tertio ordine, sunt subalternae (et ideo sunt simul verae), et deberent esse contradictoriae; et ideo erraverunt antiqui.
Aristotle replies here to this objection by destroying what was assumed in the minor, namely, that the necessary of the first order and the necessary of the third order are contradictories. He says, for the negation of “necessary not to be” (which is in the third order) is not “not necessary to be” (which has been placed in the first order). He also gives the reason: it is possible for both to be true at once of the same subject, which is repugnant to contradictories. For the same thing which is necessary not to be, is not necessary to be; for example, it is necessary that man not be wood and it is not necessary that man be wood. Notice, as will be clear later, that these two, which the ancients posited in the first and third orders, are subalterns and therefore are at once true, when they should be contradictories; hence the ancients were in error.
Peri.L10
316. Boethius autem et Averroes non reprehensive legunt tam hanc, quam praecedentem textus particulam, sed narrative utramque simul iungentes. Narrare enim aiunt Aristotelem qualitatem suprascriptae figurae quoad consequentiam illarum de necessario, postquam narravit quo modo se habuerint illae de impossibili, et dicere quod secundum praescriptam figuram non eodem modo sequuntur illas de possibili illae de necessario, quo sequuntur illae de impossibili. Nam contradictorias de possibili contradictoriae de impossibili sequuntur, licet conversim; contradictoriae autem de necessario non dicuntur sequi illas contradictorias de possibili, sed potius eas sequi dicuntur contrariae de necessario: non inter se contrariae, sed hoc modo, quod affirmationem possibilis negatio de necessario sequi dicitur, negationem vero possibilis non affirmatio de necessario sequi ponitur, quae sit contradictoria illi negativae quae ponebatur sequi ad possibilem, sed talis affirmationis de necessario contrario. Et quod hoc ita fiat in illa figura ut dicimus, patet ex primo et tertio ordine, quorum capita sunt negatio et affirmatio possibilis, et extrema sunt, non necesse esse, et, necesse non esse. Hae siquidem non sunt contradictoriae. Non enim est negatio eius, quae est, necesse non esse, non necesse esse (quoniam contingit eas simul verificari de eodem), sed illa scilicet, necesse non esse, est contraria contradictoriae huius, scilicet, non necesse esse, quae est, necesse est esse.
Boethius and Averroes read both this and the preceding part of the text not reprovingly, but as explanatorily joined together. They say Aristotle explains the quality of the above table with respect to the consequents of enunciations predicating necessity after he has explained in what way those predicating impossibility are related. What Aristotle is saying, then, is that those of the necessary do not follow those of the possible in the same way as those of the impossible follow upon the possible. For contradictories of the impossible follow upon contradictories of the possible, although inversely; but contradictories of the necessary are not said to follow the contradictories of the possible, but rather the contraries of the necessary follow upon them. It is not the contraries among themselves that follow, but contraries in this way: the negation of the necessary is said to follow upon the affirmation of the possible; but what follows on the negation of this possible is not the affirmation of the necessary contradictory to that negative of the necessary following upon the possible, but the contrary of such an affirmation of the necessary. That this is the case is evident in the first and third orders. The sources are negation and affirmation of the possible, and the extremes are “not necessary to be” and “necessary not to be.” But these are not contradictories, for the negation of “necessary not to be” is not “not necessary to be,” for it is possible for them to be at once true of the same thing. “Necessary not to be” is the contrary of the contradictory of “not necessary to be,” which contradictory is “necessary to be.”
Peri.L10
Sed quia sequenti litterae magis consona est introductio nostra, quae etiam Alberto consentit, et extorte videtur ab aliis exponi ly contrariae, ideo prima, iudicio meo, acceptanda est expositio et ad antiquorum reprehensionem referendus est textus.
In my judgment, however, the first exposition should be accepted and this portion of the text taken as a reproof of the ancients, because the contraries seem to be explained in a forced way by others, whereas our introduction is more in accord with what follows in the next part of the text; in addition, it agrees with Albert’s interpretation.
Peri.L10
317. Tertio cum dicit: causa autem cur etc., manifestat id quod praemiserat, scilicet, quod non simili modo ad illas de possibili sequuntur illae de impossibili et illae de necessario. Antiquorum enim hoc peccatum fuit tam in primo quam in secundo ordine, et quod simili modo intulerunt illas de impossibili et necessario. In primo siquidem ordine, sicut posuerunt negativam simplicem de impossibili, ita posuerunt negativam simplicem de necessario, et similiter in secundo ordine utranque negativam declinatam locaverunt. Hoc ergo quare peccatum sit, et causa autem quare necessarium non sequitur possibile, similiter, idest, eodem modo cum caeteris, scilicet, de impossibili, est, quoniam impossibile redditur idem valens necessario, idest, aequivalet necessario, contrarie, idest, contrario modo sumptum, et non eodem modo. Nam si, hoc esse est impossibile, non inferemus, ergo hoc esse est necesse, sed, hoc non esse est necesse. Quia ergo impossibile et necesse mutuo se sequuntur, quando dicta eorum contrario modo sumuntur, et non quando dicta eorum simili modo sumuntur, sequitur quod non eodem modo ad possibile se habeant impossibile et necessarium, sed contrario modo. Nam ad id possibile quod sequitur dictum affirmatum de impossibili, sequitur dictum negatum de necessario; et e contrario. Quare autem hoc accidit infra dicetur. Erraverunt igitur antiqui quod similes enunciationes de impossibili et necessario in primo et in secundo ordine locaverunt.
Third, when he says, now the reason why enunciations (22b3), he shows why enunciations predicating impossibility and necessity do not follow in a similar way upon those predicating possibility. This was the error made by the ancients in both the first and second orders, for in the first order they posited the simple negative of the impossible, and in a similar way the simple negative of the necessary, and in the second order their declined negatives, the reason being that they inferred those predicating impossibility and necessity in a similar way. The cause of this error, then, and the reason why enunciations predicating necessity do not follow the possible in the same way, that is, in a similar mode, as the others, that is, as the impossibles, is that the impossible expresses the same meaning as the necessary, that is, is equivalent to the necessary, contrarily, that is, taken in a contrary mode, and not in the same mode. For if something is impossible to be, we do not infer that therefore it is necessary to be, but that it is necessary not to be. Since, therefore, the impossible and necessary mutually follow each other when their dictums are taken in a contrary mode—and not when their dictums are taken in a similar mode—it follows that the impossible and necessary are not related in the same way to the possible, but in a contrary way. For the negated dictum of the necessary follows upon that possible which follows the affirmed dictum of the impossible, and contrarily. Why this is so will be explained later. Therefore, the ancients erred when they located similar enunciations of the impossible and necessary in the first and in the second orders.
Peri.L10
318. Hinc apparet quod supra posita nostra expositio conformior est Aristoteli. Cum enim hunc textum induxerit ad manifestandum illa verba: manifestum est autem quoniam non eodem modo, etc., eo accipiendo sunt sensu illa verba, quo hic per causam manifestantur. Liquet autem quod hic redditur causa dissimilitudinis verae inter necessarias et impossibiles in consequendo possibiles, et non dissimilitudinis falso opinatae ab antiquis: quoniam ex vera causa nonnisi verum concluditur. Ergo reprehendendo antiquos, veram dissimilitudinem inter necessarias, et impossibiles in consequendo possibiles, quam non servaverunt illi, proposuisse tunc intelligendum est, et nunc eam manifestasse. Quod autem dissimilitudo illa, quam antiqui posuerunt inter necessarias et impossibiles, sit falso posita, ex infra dicendis patebit. Ostendetur enim quod contradictorias de possibili contradictoriae de necessario sequuntur conversim; et quod in hoc non differunt ab his quae sunt de impossibili, sed differunt in hoc quod modo diximus, quod possibilium et impossibilium se consequentium dictum est similiter, possibilium autem et necessariorum, se invicem consequentium dictum est contrarium, ut infra clara luce videbitur.
Hence it appears that our exposition is more in conformity with Aristotle. For he introduced this text to manifest these words: it is evident that the case here is not the same (22a38). By taking this meaning, then, these words are made clear through the cause. Moreover, it is evident that here the cause is given of a true dissimilitude between necessaries and impossibles in following the possibles, and not of a dissimilitude falsely held by the ancients, for from a true cause only the truth is concluded. Therefore, in reproving the ancients, it must be understood that a true dissimilitude between the necessary and impossible in following the possible, which they did not heed, has been proposed, and now has been made manifest. It will be clear from what will be said later that the dissimilitude posited by the ancients between the necessary and impossible is falsely posited, for it will be shown that contradictories of the necessary follow contradictories of the possible inversely, and that in this they do not differ from enunciations predicating impossibility. They do differ, however, in the way we have indicated—namely, the dictum of the possibles and of the impossibles following on them is similar, but the dictum of the possibles and of the necessaries following on them is contrary, as will be seen clearly later.
Peri.L10
319. Quarto cum dicit: aut certe impossibile est etc., manifestat aliud quod proposuerat, scilicet, quod contradictoriae de necessario male situatae sint secundum consequentiam ab antiquis, qui contradictiones necessarii ita ordinaverunt. In primo ordine posuerunt contradictoriam negationem, necesse esse, idest, non necesse esse; et in secundo contradictoriam negationem, necesse non esse, idest, non necesse non esse.
Fourth, when he says, or is it impossible to arrange the contradictions (22b10), he manifests another point he had proposed, namely, that contradictories of enunciations predicating necessity were badly placed according to consequence by the ancients when they ordered them with the contradictory negation to “necessary to be” (namely, “not necessary to be”) in the first order, and the contradictory negation to “necessary not to be” (namely, “not necessary not to be”) in the second.
Peri.L10
Et probat hunc consequentiae modum esse malum in primo ordine. Cognita enim malitia primi, facile est secundi ordinis agnoscere defectum. Probat autem hoc tali ratione ducente ad impossibile. Ad necessarium esse sequitur possibile esse: aliter sequeretur non possibile esse, quod manifeste implicat; ad possibile esse sequitur non impossibile esse, ut patet; ad non impossibile esse, secundum antiquos, sequitur in primo ordine non necessarium esse; ergo de primo ad ultimum, ad necessarium esse sequitur non necessarium esse: quod est inconveniens, quia est manifesta implicatio contradictionis. Relinquitur ergo quod male dictum sit, quod non necessarium esse consequatur in primo ordine.
Aristotle only proves that this mode of consequence is incorrect in the first order, for when this is known the mistake in the second order is readily seen. He does this by an argument leading to an impossibility. “Possible to be” follows upon “necessary to be”; otherwise “not possible to be” would follow, which it manifestly implies. “Not impossible to be” follows upon “possible to be” as is evident, and, according to the ancients, in the first order, “not necessary to be” follows upon “not impossible to be.” Therefore, from first to last, “not necessary to be” follows upon “necessary to be,” which is inadmissible because there is an obvious implication of contradiction. Therefore, it is erroneous to say that “not necessary to be” follows in the first order.
Peri.L10
Ait ergo et certe impossibile est poni sic secundum consequentiam, ut antiqui posuerunt, necessarii contradictiones, idest illas duas enunciationes de necessario, quae sunt negationes contradictoriae aliarum duarum de necessario. Nam ad id quod est, necessarium esse, sequitur, possibile est esse: nam si non, idest quoniam si hanc negaveris consequentiam, negatio possibilis sequitur illam, scilicet, necesse esse. Necesse est enim de necessario aut dicere, idest affirmare possibile, aut negare possibile: de quolibet enim est affirmatio vel negatio vera. Quare si dicas quod, ad necesse esse, non sequitur, possibile esse, sed, non possibile est esse; cum haec aequivaleat illi quae dicit, impossibile est esse, relinquitur quod ad, necesse esse, sequitur, impossibile esse, et idem erit, necesse esse et impossibile esse: quod est inconveniens. Bona ergo erat prima illatio, scilicet, necesse est esse, ergo possibile est esse. Tunc ultra. Illud quod est, possibile esse, sequitur, non impossibile esse, ut patet in primo ordine. Ad hoc vero, scilicet, non impossibile esse, secundum antiquos eodem primo ordine, sequitur, non necesse est esse (quare contingit de primo ad ultimum); ad id quod est, necessarium esse, sequitur, non necessarium esse: quod est inconveniens, immo impossibile.
He says, then, that in fact it is impossible to posit contradictions of the necessary according to consequence as the ancients posited them, namely, with the contradictory negation of “necessary to be” (that is, “not necessary to be”) in the first order, and in the second the contradictory negation of “necessary not to be,” (that is, “not necessary not to be”). For “possible to be” follows upon “necessary to be”; if not, that is, if you deny this consequence, the negation of the possible follows upon “necessary to be,” since the possible must either be asserted of the necessary or denied, because there is a true affirmation or a true negation of everything. Therefore, if you say that “possible to be” does not follow upon “necessary to be,” but “not possible to be” does follow, then, since the latter is equivalent to the former (“not possible to be” to “impossible to be”), “impossible to be” follows upon “necessary to be,” and the same thing will be “necessary to be” and “impossible to be,” which cannot be admitted. Consequently, the first inference was good, namely, “it is necessary to be, therefore it is possible to be.” But again, “possible to be” follows upon “not impossible to be,” as is evident in the first order, and according to the ancients, “not necessary to be” follows upon “not impossible to be” in the same first order. Therefore, from first to last we arrive at this: “not necessary to be” follows upon “necessary to be,” which is unlikely, not to say impossible.
Peri.L10
320. Dubitatur hic: quia in I priorum dicitur quod ad possibile sequitur non necessarium, hic autem dicitur oppositum. Ad hoc est dicendum quod possibile sumitur dupliciter.
There is a doubt about this, for in Prior Analytics 1.13 (32a28, 32b15), it is said that the not necessary follows upon the possible, while here the opposite is said. The possible, however, is taken in two ways:
Peri.L10
Uno modo in communi, et sic est quoddam superius ad necessarium et contingens ad utrunque, sicut animal ad hominem et bovem; et sic ad possibile non sequitur non necessarium, sicut ad animal non sequitur non homo.
In one way, commonly, and thus it is higher than the necessary and the contingent to either of two alternatives, as is the case with animal in relation to man and cow. Taken in this way, the not necessary does not follow upon the possible, just as not-man does not follow upon animal.
Peri.L10
Alio modo sumitur possibile pro una parte possibilis in communi, idest pro possibili seu contingenti, scilicet ad utrunque, scilicet quod potest esse et non esse; et sic ad possibile sequitur non necessarium. Quod enim potest esse et non esse, non necessarium est esse, et similiter non necessarium est non esse.
In another way, it is taken for one part of what is possible commonly, that is, for the possible or contingent to either of two alternatives (namely, for what can be and not be). The not necessary follows upon the possible taken in this way, for what can be and not be is not necessary to be, and likewise is not necessary not to be.
Peri.L10
Loquimur ergo hic de possibili in communi, ibi vero in speciali.
In the Prior Analytics, then, Aristotle is speaking of the possible in particular; here of the possible commonly.
Peri.L10
321. Deinde cum dicit: at vero neque necessarium etc., determinat veritatem intentam.
When he says, but in fact neither “necessary to be” nor “necessary not to be” follow (22b17), he determines the truth.
Peri.L10
Et circa hoc duo facit:
About this he does two things.
Peri.L10
primo, determinat quae enunciatio de necessario sequatur ad possibile;
First, he determines which enunciation of the necessary follows upon the possible;
Peri.L10
secundo, ordinat consequentias omnium modalium; ibi: sequuntur enim et cetera.
second, he orders the consequents of all of the modals, at: thus, these contradictions also follow in the way indicated (22b26; [326]).
Peri.L10
Quoad primum, sicut duabus viis reprehendit antiquos, ita ex illis duobus motivis intentum probat. Et intendit quod, ad possibile esse, sequitur, non necesse non esse.
Aristotle has reproved the ancients in two ways; on the basis of these two he now proves which enunciation of the necessary follows upon the possible. What he intends to show is that “not necessary not to be” follows upon “possible to be.”
Peri.L10
Primum motivum est per locum a divisione. Ad, possibile esse, non sequitur (ut probatum est), non necesse esse, at vero neque, necesse esse, neque, necesse non esse. Reliquum est ergo ut sequatur ad eam, non necesse non esse: non enim dantur plures enunciationes de necessario.
The first argument is taken from a locus of division. “Not necessary to be” does not follow upon possible to be” (as has been proved), but neither does “necessary to be” nor “necessary not to be.” Therefore, “not necessary not to be” follows upon “possible to be,” since there are no more enunciations of the necessary.
Peri.L10
Huius communis divisionis primo proponit reliqua duo membra excludenda, dicens: at vero neque necessarium esse, neque necessarium non esse, sequitur ad possibile non esse;
He first proposes the remaining two members that are to be excluded from this common division: but in fact neither “necessary to be” nor “necessary not to be” follow upon “possible to be” (22b17).
Peri.L10
secundo probat hoc sic. Nullum formale consequens minuit suum antecedens: tunc enim oppositum consequentis staret cum antecedente; sed utrumque horum, scilicet, necesse esse, et, necesse non esse, minuit possibile esse; ergo, et cetera. Unde, tacita maiore, ponit minoris probationem dicens: illi enim, scilicet, possibile esse, utraque, scilicet, esse et non esse, contingit accidere; horum autem, scilicet, necesse esse et necesse non esse, utrumlibet verum fuerit, non erunt illa duo, scilicet, esse et non esse, vera simul in potentia.
Second, he proves this. No formal consequent diminishes its antecedent, for if it did, the opposite of the consequent would stand with the antecedent; but both of these, namely, “necessary to be” and “necessary not to be,” diminish “possible to be”; therefore, etc. The major is therefore implied. Hhe gives the proof of the minor when he says that “possible to be” admits of two possibilities, namely, “to be” and “not to be”; but of these, namely, “necessary to be” and “necessary not to be” (whichever should be true), these two (“to be” and “not to be”) will not be true at the same time in potency.
Peri.L10
Et primum horum explanans ait: cum dico, possibile esse, simul est possibile esse et non esse.
He explains the first point thus: when I say “possible to be,” it is at once possible to be and not to be.
Peri.L10
Quoad secundum vero subdit. Si vero dicas, necesse esse vel necesse non esse, non remanet utrumque, scilicet, esse et non esse, possibile: si enim necesse est esse, possibilitas ad non esse excluditur; et si necesse est non esse, possibilitas ad esse removetur. Utrumque ergo istorum minuit illud antecedens, possibile esse, quoniam ad esse et non esse se extendit, et cetera.
With respect to the second, he adds: if you should say, “necessary to be” or “necessary not to be,” both do not remain (that is, possible to be and not to be do not remain), for if a thing is necessary to be, possibility not to be is excluded, and if it is necessary not to be, possibility to be is removed. Both of these, then, diminish the antecedent, “possible to be,” for it is extended to “to be” and “not to be.”
Peri.L10
Tertio subdit conclusionem: relinquitur ergo quod, non necessarium non esse, comes est ei quae dicit, possibile esse; et consequenter haec ponenda erit in primo ordine.
Third, he concludes that it remains, therefore, that “not necessary not to be” accompanies “possible to be,” and consequently will have to be placed in the first order.
Peri.L10
322. Occurrit in hac parte dubium circa hoc quod dicit quod, ad possibile non sequitur necessarium, cum superius dixerit quod ad ipsum non sequitur non necessarium. Cum enim necessarium et non necessarium sint contradictoria opposita, et de quolibet sit affirmatio vel negatio vera, non videtur posse evadi quin ad possibile sequatur necessarium, vel, non necessarium. Et cum non sequatur necessarium, sequetur non necessarium, ut dicebant antiqui. Augetur et dubitatio ex eo quod Aristoteles nunc usus est tali argumentationis modo, volens probare quod ad necessarium sequatur possibile. Dixit enim: nam si non negatio possibilis consequatur. Necesse est enim aut dicere aut negare.
A difficulty arises at this point with respect to his saying that the necessary does not follow upon the possible, since he has also said that the not necessary does not follow upon it. For the necessary and the not necessary are opposed contradictorily, and since of anything there is a true affirmation or negation, it seems impossible to avoid the conclusion that either the necessary or the not necessary follows upon the possible; and since the necessary does not follow, the not necessary must follow, as the ancients said. Furthermore, the difficulty is augmented by the fact that Aristotle just used such a mode of argumentation when, to prove that the possible follows upon the necessary, he said, for if not, the negation will follow (22b10); for it is necessary either to affirm or deny.
Peri.L10
323. Pro solutione huius, oportet reminisci habitudinis quae est inter possibile et necessarium, quod scilicet possibile est superius ad necessarium, et attendere quod superius potestate continet suum inferius et eius oppositum, ita quod neutrum eorum actualiter sibi vindicat, sed utrunque potest sibi contingere; sicut animali potest accidere homo et non homo: et consequenter inspicere debes quod, eadem est proportio superioris ad habendum affirmationem et negationem unius inferioris, quae est alicuius subiecti ad affirmativam et negativam futuri contingentis. Utrobique enim neutrum habetur, et salvatur potentia ad utrumlibet. Unde, sicut in futuris contingentibus nec affirmatio nec negatio est determinate vera, sed sub disiunctione altera est necessario vera, ut in fine primi conclusum est; ita nec affirmatio nec negatio inferioris sequitur determinate affirmationem vel negationem superioris, sed sub disiunctione altera sequitur necessario. Unde non valet, est animal, ergo est homo, neque, ergo non est homo, sed, ergo est homo vel non est homo. Quia ergo possibile superius est ad necessarium, ideo optime determinavit Aristoteles neutram contradictionis partem de necessario determinate sequi ad possibile. Non tamen dixit quod sub disiunctione neutra sequatur; hoc enim est contra illud primum principium: de quolibet est affirmatio vera vel falsa.
In order to resolve this, we must recall the relationship between the possible and the necessary, namely, that the possible is higher than the necessary. Now the superior potentially contains its own inferior and the opposite of it in such a way that neither of them is actually appropriated by the higher, but each is possible to it, as in the case of man and not-man in relation to animal. We must also consider that the proportion of the superior as related to the affirmation and negation of one inferior is the same (which is the proportion of some subject to the affirmative and negative of a future contingent), for it is had by neither of the two, and the potency to either is kept. Accordingly, as in future contingents neither the affirmation nor the negation is determinately true, but under disjunction one is necessarily true (as was concluded at the end of the first book), so neither the affirmation nor negation of the inferior follows upon the affirmation or negation of the superior determinately, but one follows necessarily under disjunction. For instance, neither “it is animal; therefore, it is man,” nor “therefore, it is not man” is valid; but “therefore, it is man or it is not man” is valid. Since, then, the possible is higher than the necessary, Aristotle has correctly determined that neither part of the contradiction of the necessary determinately follows upon the possible. However, he has not said that under disjunction neither follows; for this would be opposed to the first principle that of anything there is a true or false affirmation.
Peri.L10
Ad id autem quod additur, ex eadem trahitur radice responsio. Quia enim necessarium inferius est ad possibile, et inferius non in potentia sed in actu includit suum superius, necesse est ad inferius determinate sequi suum superius: aliter determinate sequetur eius contradictorium. Unde per dissimilem habitudinem, quae est inter necessarium et possibile et non possibile, ex una parte, et inter possibile et necessarium et non necessarium, ex altera parte, ibi optimus fuit processus ad alteram contradictionis partem determinate, et hic optimus ad neutram determinate.
The response to what was added is based upon the same point. Since the necessary is inferior to the possible, and the inferior does not include its superior in potency but in act, the superior must follow determinately upon the inferior; otherwise, the contradiction of it would follow determinately. Hence, because of the dissimilar relationship between the necessary, the possible, and the not possible on the one hand, and between the possible, the necessary, and the not necessary on the other, the movement of the earlier argument to one part of the contradiction determinately was quite right, and the movement here to neither determinately was quite right.
Peri.L10
324. Oritur quoque alia dubitatiuncula. Videtur enim quod Aristoteles difformiter accipiat ly possibile in praecedenti textu et in isto. Ibi enim accipit ipsum in communi, ut sequitur ad necessarium; hic videtur accipere ipsum specialiter pro possibili ad utrumlibet, quia dicit quod possibile est simul potens esse et non esse. Et ad hoc dicendum est quod uniformiter usus est possibili. Nec eius verba obstant: quoniam et de possibili in communi verum est dicere quod potest sibi utrunque accidere, scilicet, esse et non esse:
There is another slight difficulty, for it seems that Aristotle takes the possible in a different way in the preceding text and in this. There he takes it commonly as it follows upon the necessary; here he seems to take it specifically for the possible that is indifferent to alternatives, since he says that the possible is at once possible to be and not to be. But in fact Aristotle has used the possible uniformly. Nor are his words at variance, for it is also true to say of the possible as common that it admits of both possibilities, namely, of “to be” and “not to be”:
Peri.L10
tum quia quidquid verificatur de suo inferiori, verificatur etiam de suo superiori, licet non eodem modo;
first, because whatever is verified of its inferior is verified also of its superior, although not in the same mode;
Peri.L10
tum quia possibile in communi neutram contradictionis partem sibi determinat, et consequenter utranque sibi advenire compatitur, licet non asserat potentiam ad utranque partem, quemadmodum possibile ad utrunque.
second, because the possible as common determines neither part of the contradiction to itself and consequently admits of either happening, although it does not affirm a potency to each part, as does the possible to either of two alternatives.
Peri.L10
325. Secundum motivum ad idem, correspondens tacitae obiectioni antiquorum quam supra exclusit, addit cum subdit: hoc enim verum est et cetera. Ubi notandum quod Aristoteles sub illa maiore adducta pro antiquis (scilicet, convertibiliter se consequentium contradictoria se mutuo consequuntur), subsumit minorem: sed horum convertibiliter se sequentium in tertio ordine (scilicet, non possibile esse et necesse non esse), contradictoria sunt, possibile esse et non necesse non esse (quoniam modi negatione eis opponuntur); ergo istae duae (scilicet, possibile esse et non necesse non esse) se consequuntur et in primo locandae sunt ordine.
The second grounds for proving the same thing corresponds to the tacit objection of the ancients he excluded above: for this, he says, is true also with respect to “necessary to be" (22b23). It should be noted here that Aristotle subsumes under the major cited as a proof for the position of the ancients (namely, contradictories of consequences convertibly following each other mutually follow upon each other) this minor. The contradictories of those following upon each other convertibly in the third order (that is, of “not possible to be” and “necessary not to be”) are “possible to be” and “not necessary not to be” (for they are opposed to them by negation of mode). Therefore, these two (namely, “possible to be” and “not necessary not to be”) follow upon each other and are to be placed in the first order.
Peri.L10
Unde motivum tangens ait: hoc enim, quod dictum est, verum est, idest verum esse ostenditur, et de necesse non esse, idest, et ex illius, scilicet, non necesse non esse, opposita, quae est, necesse non esse. Vel, hoc enim, scilicet, non necesse non esse, verum est, scilicet, contradictorium illius de necesse non esse.
Hence, with respect to the basis of the above argument, he says, for this, that is, what has been said, is true, namely, is shown to be true, also with respect to “necessary not to be,” namely, of the opposite of “not necessary not to be,” which is “necessary not to be.” Or, for this, namely, “not necessary not to be,” is true, namely, is the true contradictory of “necessary not to be.”
Peri.L10
Et minorem subdens ait: haec enim, scilicet, non necesse non esse, fit contradictio eius, quae convertibiliter sequitur, non possibile esse.
He gives the minor when he says, for “not necessary not to be” is the contradictory of what follows upon “not possible to be”(22b23).
Peri.L10
Et explanans hoc in terminis subdit. Illud enim, non possibile esse, quod est caput tertii ordinis, sequitur hoc de impossibili, scilicet, impossibile esse, et haec de necessario, scilicet, necesse non esse, cuius negatio seu contradictoria est, non necesse non esse. Et quia, caeteris paribus, modus negatur, et illa, possibile esse, est (subauditur) contradictoria illius, scilicet, non possibile; igitur ista duo mutuo se consequuntur, scilicet, possibile esse, et, non necesse non esse, tamquam contradictoria duorum se mutuo consequentium.
Then he states this explicitly. “Not possible to be,” which is the source of the third order, is followed by this impossible, namely, “impossible to be,” and by this one of the necessary, namely, “necessary not to be,” of which the negation or contradictory is “not necessary not to be.” And since, other things being equal, the mode is negated, and “possible to be” is (it is understood) the contradictory of “not possible to be,” therefore, these two (namely, “possible to be” and “not necessary not to be”) mutually follow upon each other as contradictories of the two mutually following upon each other.
Peri.L10
326. Deinde cum dicit: sequuntur enim etc., ordinat omnes consequentias modalium secundum opinionem propriam; et ait quod, hae contradictiones, scilicet, de necessario, sequuntur illas de possibili, secundum modum praedictum et approbatum illarum de impossibili. Sicut enim contradictorias de possibili contradictoriae de impossibili sequuntur, licet conversim; ita contradictorias de possibili contradictoriae de necessario sequuntur conversim: licet in hoc, ut dictum est, dissimilitudo sit quod, contradictoriarum de possibili et impossibili similiter est dictum, contradictoriarum autem de possibili et necessario contrarium est dictum, ut in sequenti videtur figura: consequentiae enunciationum modalium secundum quatuor ordines ab Aristotele positae et ordinatae. (Figura).
When he says, thus, these contradictions also follow in the way indicated (22b26), he orders all of the consequents of modals according to his own opinion. He says, then, that these contradictions of the necessary follow those of the possible, according to the foresaid and approved mode of those of the impossible. For just as contradictories of the impossible follow upon contradictories of the possible, although inversely, so contradictories of the necessary follow contradictories of the possible inversely. In the latter, however, as has been said, there is a dissimilarity in that the dictum of the contradictories of the possible and impossible is similar, but the dictum of the contradictories of the possible and necessary is contrary. This can be seen in the following table of the consequents of modal enuniciations posited and ordered by Aristotle according to four orders.
Peri.L10
FIRST ORDERIt is possible to beIt is contingent to beIt is not impossible to beIt is not necessary to be
Peri.L10
SECOND ORDERIt is possible not to beIt is contingent not to beIt is not impossible not to beIt is not necessary not to be
Peri.L10
THIRD ORDERIt is not possible to beIt is not contingent to beIt is impossible to beIt is necessary not to be
Peri.L10
FOURTH ORDERIt is not possible not to beIt is not contingent not to beIt is impossible not to beIt is necessary to be
Peri.L10
Ubi vides quod nulla est inter Aristotelem et antiquos differentia, nisi in duobus primis ordinibus quoad illas de necessario. Praepostero namque situ usi sunt antiqui, eam de necessario, quae locanda erat in primo ordine, in secundo ponentes, et eam quae in secundo ponenda erat, in primo locantes. Et aspice quoque quod convertibiliter se consequentium semper contradictoria se consequi ordinavit. Singulis enim tertii ordinis singulae primi ordinis contradictoriae sunt; et similiter singulae quarti ordinis singulis, quae in secundo sunt, contradictoriae sunt. Quod antiqui non observarunt.
Here you see that there is no difference between Aristotle and the ancients except in the first two orders with respect to those of the necessary. The ancients inverted the position of these, placing the necessary that should have been placed in the first order in the second order, and the one that should have been in the second in the first. Notice, too, that he has ordered them in such a way that the contradictories of those following upon each other convertibly, always follow each other, for each one in the first order is the contradictory of each one in the third order, and similarly, each of the fourth order the contradictory of each in the second. This the ancients did not observe.
Peri.L10
L. 11 (1.13, 22b29–23a6)Whether “Possible to Be” Follows Upon “Necessary to Be”
Whether “Possible to Be” Follows Upon “Necessary to Be”
Peri.L11
Dubitabit autem aliquis, si ad illud quod est, necessarium esse, illud quod est, possibile esse, sequatur. Nam si non sequatur, contradictio sequetur, quae est, non possibile esse: et si quis hanc non dicat esse contradictionem, necesse est dicere, possibile non esse: quae utraeque falsae sunt de necesse esse.
22b29. But it may be asked whether “possible to be” follows upon “necessary to be.” Yet if not, the contradictory, “not possible to be,” would have to follow; or if someone should say that this is not the contradictory, then “possible not to be.” But both of these are false in regard to that which is necessary to be.
Peri.L11
At vero rursus idem videtur esse possibile aliquid incidi et non incidi, et esse et non esse: quare erit necesse esse, contingens non esse. Hoc autem falsum est.
22b33. On the other hand, it seems possible for the same thing to be cut and not to be cut, and to be and not to be, and thus it would follow that what is necessary to be is possible not to be, which is false.
Peri.L11
Manifestum est autem quod non omne possibile, vel esse, vel ambulare, etiam opposita potest; sed est in quibus non sit verum. Primum quidem in his quae non secundum rationem possunt; ut ignis calefactibilis est, et habet vim irrationalem. Quae igitur secundum rationem potestates sunt, eaedem plurium etiam contrariorum sunt. Irrationales vero non omnes: sed (quemadmodum dictum est) ignem non esse possibile calefacere et non; neque quaecumque alia seraper agunt. Alia vero possunt, et secundum irrationales potestates simul opposita suscipere. Sed hoc huius gratia: dictum est, quoniam non omnis potestas oppositorum susceptiva est, neque quaecumque secundum eamdem speciem dicuntur.
22b36. It is evident by now that not every possibility of being or walking is one that admits of opposites. There are those of which this is not true. First of all, this is not true of potentialities which are not according to reason, like fire, which has an irrational potentiality (the power to heat). Potentialities that are in conjunction with reason are capable of more than one and of contraries, but not all irrational potentialities are capable of contraries; as has been said, fire does not have the potentiality to heat and not to heat, nor does anything that always acts have this potentiality. However, even some of the irrational potencies are simultaneously capable of opposites. We have spoken of this in order to show that not every potentiality is a potentiality to opposites, not even all those that are called potentialities according to the same notion.
Peri.L11
327. Postquam Aristoteles declaravit modalium consequentias, hic movet quandam dubitationem circa unum eorum quae determinata sunt, scilicet quod possibile sequitur ad necesse.
Now that he has explained the consequents of modals, Aristotle raises a question about one of the points that has already been determined, namely, that the possible follows upon the necessary.
Peri.L11
Et duo facit:
He does two things:
Peri.L11
quia primo dubitationem absolvit;
first, he raises the question;
Peri.L11
secundo, ex determinata quaestione alium ordinem earumdem consequentiarum modalibus statuit; ibi: et est fortasse et cetera.
second, he establishes another order of the same consequents from the determination of the present question, at: indeed, the necessary and not necessary may well be (23a18; [341]).
Peri.L11
Circa primum duo facit:
About the first he does two things:
Peri.L11
primo, movet quaestionem;
first, he raises the question;
Peri.L11
secundo, determinat eam; ibi: manifestum est et cetera.
second, he settles it, at: it is evident by now that not every possibility (22b36; [329]).
Peri.L11
Movet ergo quaestionem: primo dicens: dubitabit autem aliquis si ad id quod est necesse esse sequatur possibile esse;
First, then, he raises the question: but it may be questioned whether “possible to be" follows upon “necessary to be” (22b29).
Peri.L11
et secundo, arguit ad partem affirmativam subdens: nam si non sequatur, contradictoria eius sequetur, scilicet non possibile esse, ut supra deductum est: quia de quolibet est affirmatio vel negatio vera. Et si quis dicat hanc, scilicet, non possibile esse, non esse contradictoriam illius, scilicet, possibile esse, et propterea subterfugiendum velit argumentum, et dicere quod neutra harum sequitur ad necesse esse; talis licet falsum dicat, tamen concedatur sibi, quoniam necesse erit ipsum dicere illius contradictoriam fore, possibile non esse. Oportet namque aut non possibile esse aut possibile non esse, esse contradictoriam, possibile esse; et tunc in eumdem redibit errorem, quoniam utraeque, scilicet, non possibile esse et possibile non esse, falsae sunt de eo quod est, necesse esse. Et consequenter ad ipsum neutra sequi potest. Nulla enim enunciatio sequitur ad illam, cuius veritatem destruit. Relinquitur ergo quod, ad necesse esse sequitur possibile esse.
Second, he argues to the affirmative part: yet if not, the contradictory, “not possible to be” (22b29), would have to follow, as was deduced earlier, for either the affirmation or the negation is true of anything. And if someone should say “not possible to be” is not the contradictory of “possible to be,” because he wants to avoid the conclusion by saying that neither of these follows upon “necessary to be,” this may be conceded, although what he says is false. But then he will have to say that the contradictory of “possible to be” is “possible not to be,” for the contradictory of “possible to be” has to be either “not possible to be” or “possible not to be.” But if he says this, he will fall into another error, for it is false to say it is not possible to be of that which is necessary to be, and it is false to say it is possible not to be. Consequently, neither follows upon it, for no enunciation follows upon an enunciation whose truth it destroys. Therefore, “possible to be” follows upon “necessary to be.”
Peri.L11
328. Tertio, arguit ad partem negativam cum subdit: at vero rursus etc., et intendit talem rationem. Si ad necesse esse sequitur possibile esse, cum ad possibile sequatur possibile non esse (per conversionem in oppositam qualitatem, ut dicitur in I priorum, quia idem est possibile esse et non esse), sequetur de primo ad ultimum quod necesse est possibile non esse: quod est falsum manifeste. Unde oppositionis hypothesim subdit: at vero rursus videtur idem possibile esse et non esse, ut domus, et possibile incidi et non incidi, ut vestis. Quare de primo ad ultimum necesse esse, erit contingens non esse. Hoc autem est falsum. Ergo hypothesis illa, scilicet, quod possibile sequatur ad necesse, est falsa.
Third, he argues to the negative part where he says, on the other hand, it seems possible for the same thing (22b33). His argument is as follows. If “possible to be” follows upon “necessary to be,” then, since “possible not to be” follows upon the possible (through conversion to the opposite quality, as is said in Prior Analytics 1.13 [32a31], for the same thing is possible to be and not to be), from first to last it will follow that the necessary is possible not to be, which is clearly false. In this argument, Aristotle supplies a hypothesis opposed to the position that possible to be follows upon necessary to be: on the other hand, it seems possible for the same thing to be cut and not to be cut, such as a garment, and to be and not to be, such as a house. Therefore, from first to last, necessary to be will be possible not to be. But this is false. Therefore, the hypothesis that the possible follows upon the necessary is false.
Peri.L11
329. Deinde cum dicit: manifestum est autem etc., respondet dubitationi.
When he says, it is evident by now that not every possibility of being or walking (22b36), he answers the question he proposed.
Peri.L11
Et primo, declarat veritatem simpliciter;
First, he manifests the truth simply;
Peri.L11
secundo, applicat ad propositum; ibi: hoc igitur possibile et cetera.
second, he applies it to the question, at: so it is not true to say (23a15; [339]).
Peri.L11
Proponit ergo primo ipsam veritatem declarandam, dicens: manifestum est autem, ex dicendis, quod non omne possibile esse vel ambulare, idest operari: idest, non omne possibile secundum actum primum vel secundum ad opposita valet, idest ad opposita viam habet, sed est invenire aliqua possibilia, in quibus non sit verum dicere quod possunt in opposita.
First, then, he proposes the truth he is going to explain, at: it is evident by now that not every possibility of being or walking, that is, of operating. He means that not everything possible according to first or second act admits of opposites (that is, has access to opposites); there are some possibles of which it is not true to say that they are capable of opposites.
Peri.L11
Deinde, quia possibile a potentia nascitur, manifestat qualiter se habeat potentia ipsa ad opposita: ex hoc enim clarum erit quomodo possibile se habeat ad opposita.
Then, since the possible arises from potency, he manifests how potency is related to opposites, for it will be clear from this how the possible is related to opposites.
Peri.L11
Et circa hoc duo facit:
About this he does two things.
Peri.L11
primo manifestat hoc in potentiis eiusdem rationis;
First, he manifests this in potencies having the same notion;
Peri.L11
secundo, in his quae aequivoce dicuntur potentiae; ibi: quaedam vero potentiae et cetera.
second, in those that are called potencies equivocally, at: but some are called potentialities equivocally (23a6 [335]).
Peri.L11
Circa primum tria facit:
About the first he does three things.
Peri.L11
quia primo manifestat qualiter potentia irrationalis se habeat ad opposita; et ait quod potentia irrationalis non potest in opposita.
First, he manifests how an irrational potency is related to opposites. He says that an irrational potency is not a potency that is capable of opposites.
Peri.L11
330. Ubi notandum est quod, sicut dicitur IX Metaphys., potentia activa, cum nihil aliud sit quam principium quo in aliud agimus, dividitur in potentiam rationalem et irrationalem. Potentia rationalis est, quae cum ratione et electione operatur; sicut ars medicinae, qua medicus cognoscens quid sanando expediat infirmo, et volens applicat remedia. Potentia autem irrationalis vocatur illa, quae non ex ratione et libertate operatur, sed ex naturali sua dispositione; sicut calor ignis potentia irrationalis est, quia calefacit, non ut cognoscit et vult, sed ut natura sua exigit. Assignatur autem ibidem duplex differentia proposito deserviens inter istas potentias.
It must be noted in this connection that active potency, since it is the principle by which we act on something else, is divided into rational and irrational potency, as is said in Metaphysics 9.2 (1046a36). Rational potency operates in connection with reason and choice, like the art of medicine, by which the physician, knowing and willing what is expedient in healing an illness, applies a remedy. Irrational potency operates according to its own natural disposition, not according to reason and liberty; for example, the heat of fire is an irrational potency, because it heats not as it knows and wills, but as its nature requires. In the Metaphysics, a twofold difference between these potencies is assigned which is relevant here.
Peri.L11
Prima est quod activa potentia irrationalis non potest duo opposita, sed est determinata ad unum oppositorum, sive sumatur oppositum contradictorie sive contrarie. Verbi gratia: calor non potest calefacere et non calefacere, quae sunt contradictorie opposita, neque potest calefacere et frigefacere, quae sunt contraria, sed ad calefactionem determinatus est. Et hoc intellige per se, quia per accidens calor frigefacere potest, vel resolvendo materiam caloris, humidum scilicet, vel per antiperistasin contrarii. Et similiter potest non calefacere per accidens, scilicet si calefactibile deest. Potentia autem rationalis potest in opposita et contradictorie et contrarie. Arte siquidem medicinae potest medicus adhibere remedia et non adhibere, quae sunt contradictoria; et adhibere remedia sana et nociva, quae sunt contraria.
The first is that an irrational active potency is not capable of two opposites, but is determined to one opposite, whether “opposite” is taken contradictorily or contrarily. For instance, heat cannot heat and not heat, which are opposed contradictorily; nor can it heat and cool, which are contraries, but is determined to heating. Understand this to be per se, for heat can cool accidentally either by destroying the matter of heat (namely, the humid) or through alternation of the contrary. It also has the potentiality not to heat accidentally, if that which can be heated is lacking. A rational potency, on the other hand, is capable of opposites, both contradictorily and contrarily; for by the art of medicine the physician can employ a remedy and not employ it, which are contradictories, and employ healing and harmful remedies, which are contraries.
Peri.L11
Secunda differentia est quod potentia activa irrationalis, praesente passo, necessario operatur, deductis impedimentis: calor enim calefactibile sibi praesens calefacit necessario, si nihil impediat; potentia autem rationalis, passo praesente, non necessario operatur: praesente siquidem infirmo, non cogitur medicus remedia adhibere.
The second difference is that an irrational active potency necessarily operates when a subject is present and impediments are withdrawn, for heat necessarily heats when a subject that can be heated is present and nothing impedes it. A rational potency, however, does not necessarily operate when a subject is present; for instance, when a sick man is present, the physician is not forced to employ a remedy.
Peri.L11
331. Dimittantur autem metaphysico harum differentiarum rationes et ad textum redeamus. Ubi narrans quomodo se habeat potentia irrationalis ad oppositum, ait: et primum quidem, scilicet, non est verum dicere quod sit potentia ad opposita in his quae possunt non secundum rationem, idest, in his quorum posse est per potentias irrationales; ut ignis calefactivus est, idest, potens calefacere, et habet vim, idest, potentiam istam irrationalem. Ignis siquidem non potest frigefacere; neque in eius potestate est calefacere et non calefacere. Quod autem dixit primum ordinem, nota, ad secundum genus possibilis infra dicendum, in quo etiam non invenitur potentia ad opposita.
The reasons for these differences are given in the Metaphysics, but let us return to the text. Explaining how an irrational potency is related to opposites, he says, first of all, this is not true, that is, it is not true to say that there is a potency to opposites in those which are not according to reason, namely, whose power is through irrational potencies; as fire which is calefactive, or capable of heating, has this power, that is, this irrational potentiality, since it is not able to cool, nor is it in its power to heat and not to heat. Note that he speaks here of a first kind. This is in relation to a second genus of the possible which he will speak of later, in which there is not a potency to opposites either.
Peri.L11
332. Secundo, manifestat quomodo potentia rationalis se habeat ad opposita, intendens quod potentia rationalis potest in opposita. Unde subdit: ergo potestates secundum rationem, idest rationales, ipsae eaedem sunt contrariorum, non solum duorum, sed etiam plurimorum, ut arte medicinae medicus plurima iuga contrariorum adhibere potest, et a multarum operationum contradictionibus abstinere potest. Praeposuit autem ly ergo, ut hoc consequi ex dictis insinuaret: cum enim oppositorum oppositae sint proprietates, et potentia irrationalis ex eo quod irrationalis ad opposita non se extendat; oportet potentiam rationalem ad opposita viam habere, eo quod rationalis sit.
Second, he shows how a rational potency is related to opposites, that is, it is capable of opposites: potentialities that are in conjunction with reason, that is, rational potencies, are capable of contraries (22b36), not only of two, but even of many. For example, a physician can employ many pairs of contraries by the art of medicine and he can abstain from doing or not doing many things. He begins with therefore so as to imply that this follows from what has been said. The argument would be that properties of opposites are opposites; an irrational potency, because it is irrational, does not extend itself to opposites; and therefore a rational potency, because it is rational, has access to opposites.
Peri.L11
333. Tertio, explanat id quod dixit de potentiis irrationalibus, propter causam infra assignandam ab ipso; et intendit quod illud quod dixit de potentia irrationali, scilicet quod non potest in opposita, non est verum universaliter, sed particulariter. Ubi nota quod potentia irrationalis dividitur in potentiam activam, quae est principium faciendi, et potentiam passivam, quae est principium patiendi: verbi gratia, potentia ad calorem dividitur in posse calefacere, et in posse calefieri. In potentiis activis irrationalibus verum est quod non possunt in opposita, ut declaratum est; in potentiis autem passivis non est verum. Illud enim quod potest calefieri, potest etiam frigefieri, quia eadem est materia, seu potentia passiva contrariorum, ut dicitur in II de caelo et mundo, et potest non calefieri, quia idem est subiectum privationis et formae, ut dicitur in I Physic.
Third, he explains what he has said about irrational potencies; he will later assign the reason for doing this. He makes the point that what he has said about irrational potentiality, namely, that it is not capable of opposites, is not true universally, but particularly. It should be noted here that irrational potency is divided into active potency, which is the principle of acting, and passive potency, which is the principle of being acted upon; for instance, potency to heat is divided into potentiality to heat and potentiality to be heated. Now it is true that active irrational potencies are not capable of opposites, as was explained. This is not true, however, of passive potencies, for what can be heated can also be cooled, because the matter is the same, or the passive potency of contraries, as is said in On the Heavens 2.7 (286a23). It can also not be heated, since the subject of privation and of form is the same, as is said in Physics 1.7 (189b32).
Peri.L11
Et propter hoc ergo explanando, ait: irrationales vero potentiae non omnes a posse in opposita excludi intelligendae sunt, sed illae quae sunt quemadmodum potentia ignis calefactiva (ignem enim non posse non calefacere manifestum est), et universaliter, quaecunque alia sunt talis potentiae, quod semper agunt, idest quod quantum est ex se non possunt non agere, sed ad semper agendum ex sua forma necessitantur. Huiusmodi autem sunt, ut declaravimus, omnes potentiae activae irrationales.
Therefore, in explaining about irrational potencies, he says that not all irrational potentialities should be understood to be excluded from the capacity of opposites. Those like the potentiality of fire to heat are to be excluded (for it is evident that fire cannot not heat), and, universally, whatever others are potencies of such a kind that they always act, that is, the ones that of themselves cannot not act, but are necessitated by their form always to act. All active irrational potencies are of this kind, as we have explained.
Peri.L11
Alia vero sunt talis conditionis quod etiam secundum irrationales potentias, scilicet passivas, simul possunt in quaedam opposita, ut aer potest calefieri et frigefieri. Quod vero ait, simul, cadit supra ly possunt, et non supra ly opposita; et est sensus, quod simul aliquid habet potentiam passivam ad utrunque oppositorum, et non quod habeat potentiam passivam ad utrunque oppositorum simul habendum. Opposita namque impossibile est haberi simul. Unde et dici solet et bene, quod in huiusmodi est simultas potentiae, non potentia simultatis. Irrationalis igitur potentia non secundum totum suum ambitum a posse in opposita excluditur, sed secundum partem eius, secundum potentias scilicet activas.
There are others, however, of such a condition that, even though they are irrational (or passive) potencies, are simultaneously capable of certain opposites; for example, air can be heated and cooled. Simultaneously modifies are capable and not opposites. What he means is that the thing simultaneously has a passive potency to each opposite, and not that it has a passive potency to have both opposites simultaneously, for it is impossible to have opposites at one and the same time. Hence it is customary and correct to say that in these there is simultaneity of potency, not potency of simultaneity. Therefore, irrational potency is excluded from the capacity of opposites, not completely, but according to its part, namely, according to active potencies.
Peri.L11
334. Quia autem videbatur superflue addidisse differentias inter activas et passivas irrationales, quia sat erat proposito ostendisse quod non omnis potentia oppositorum est; ideo subdit quod hoc idcirco dictum est, ut notum fiat quoniam nedum non omnis potestas oppositorum est, loquendo de potentia communissime, sed neque quaecunque potentiae dicuntur secundum eamdem speciem ad opposita possunt. Potentiae siquidem irrationales omnes sub una specie irrationalis potentiae concluduntur, et tamen non omnes in opposita possunt, sed passive tantum. Non supervacanea ergo fuit differentia inter passivas et activas irrationales, sed necessaria ad declarandum quod non omnes potentiae eiusdem speciei possunt in opposita. Potest et ly hoc demonstrare utranque differentiam, scilicet, inter rationales et irrationales, et inter irrationales activas et passivas inter se; et tunc est sensus, quod hoc ideo fecimus, ut ostenderemus quod non omnis potestas, quae scilicet secundum eamdem rationem potentiae physicae dicitur, quia scilicet potest in aliquid ut rationalis et irrationalis, neque etiam omnis potestas, quae sub eadem specie continetur, ut irrationalis activa et passiva sub specie irrationalis, ad opposita potest.
Because it might seem superfluous to have added the differences between active and passive irrational potencies, since enough had already been said to show that not every potency is of opposites, Aristotle gives the reason for this. It was not only to make it known that not every potency is of opposites, speaking of potency most commonly, but also that not all that are called potencies according to the same species are capable of opposites. For all irrational potencies are included under one species of irrational potency, and yet not all are capable of opposites, but only the passive potencies. It was not superfluous, therefore, to point out the difference between passive and active irrational potencies, since this was necessary in order to show that not all potencies of the same species are capable of opposites. “This” in the phrase “this has been said” could designate each difference, the one between rational and irrational potencies, and the one between active and passive irrational potencies. The meaning is, then, that we have said this to show that not every potentiality which is said according to the same notion of physical power (namely, because it can be in something as rational and irrational)—not even every potentiality which is contained under the same species, as active and passive under the species irrational—is capable of opposites.

The Explanation of Potencies That Are Called Such Equivocally and the Determination, Through the Notion of the Impossible, of the Possible that Follows Upon the Necessary
Peri.L12
Quaedam vero potestates aequivocae sunt. Possibile enim non simpliciter dicitur: sed hoc quidem, quoniam verum est, quod in actu est; ut possibile ambulare, quoniam ambulat iam, et omnino possibile esse, quoniam iam est in actu, quod dicitur esse possibile: illud vero, quoniam actu esse posset; ut possibile ambulare, quoniam ambulabit.
23a6. But some are called potentialities equivocally, for “possible” has more than one meaning. On the one hand, it is that which is true of a thing because it is in act, as walking is possible to someone because he is actually walking, and, in general, possible is said of that which is possible to be because it is already actualized. On the other hand, possible is said of that which can be actualized, as walking is possible to someone because he could walk.
Peri.L12
Et haec quidem in mobilibus solis est potestas, illa vero et in immobilibus. Utrumque vero verum est dicere, non impossibile esse ambulare vel esse, et quod iam ambulat et agit, et ambulativum.
23a11. This latter potentiality is only in that which is movable, but the former is also in the immovable. Now, it is true to say, both of that which is walking already and is actual, and of that which could walk, that it is not impossible that it walk or be.
Peri.L12
Hoc igitur possibile non est verum de necessario dicere simpliciter, alterum autem verum est. Quare quoniam partem universale sequitur, illud quod ex necessitate est, consequitur posse esse, sed non omne.
23a15. So it is not true to say the latter possible [that is, the possible which could be] of what is necessary simply, but it is true to say the former of it. Therefore, since the universal follows upon the part, possible to be follows upon that which necessarily is, though not every kind of possible does.
Peri.L12
Et est fortasse quidem principium, quod necessarium est, et quod non necessarium est, omnium vel esse, vel non esse: et alia, veluti horum consequentia, considerare oportet.
23a18. Indeed, the necessary and not necessary may well be the principle of all that is or is not and the others must be regarded as consequent to these.
Peri.L12
Manifestum est autem ex his quae dicta sunt, quod id quod ex necessitate est, secundum actum est: quare si priora sunt sempiterna, et quae actu sunt potestate priora sunt.
23a21. It is evident, then, from what has been said that that which necessarily is, actually is; and, if eternal things are prior, that actuality is prior to potentiality.
Peri.L12
Et haec quidem sine potestate actus sunt, ut primae substantiae: alia vero cum potestate, quae natura quidem priora sunt, tempore vero posteriora. Alia vero numquam actus sunt, sed potestates tantum.
23a23. Some things are actualities without potentiality, namely, the primary substances. Others are actualities with potentiality—those that are prior in nature, but posterior in time. And some never are actualities but are only potentialities.
Peri.L12
335. Intendit declarare quomodo illae quae aequivocae dicuntur potentiae, se habeant ad opposita.
Aristotle now proposes to show in what way potencies that are called equivocal are related to opposites.
Peri.L12
Et circa hoc duo facit:
About this he does two things.
Peri.L12
primo, declarat naturam talis potentiae;
First, he explains the nature of this kind of potency;
Peri.L12
secundo, ponit differentiam et convenientiam inter ipsas et supradictas, ibi: et haec quidem et cetera.
second, he gives the difference and agreement all between these and the foresaid, where he says, this latter potentiality is only (23a11; [337]).
Peri.L12
Ad evidentiam primi advertendum est quod V et IX Metaphys., Aristoteles dividit potentiam in potentias, quae eadem ratione potentiae dicuntur, et in potentias, quae non ea ratione qua praedictae potentiae nomen habent, sed alia. Et has appellat aequivoce potentias.
In Metaphysics 5.12 (1019a15) and 12.1 (1046a4), Aristotle divides potency into those that are called potencies for the same reason, and those that have the name potency for another reason than the aforesaid potencies. The latter are named “potencies” equivocally.
Peri.L12
Sub primo membro comprehenduntur omnes potentiae activae, et passivae, et rationales, et irrationales. Quaecunque enim posse dicuntur per potentiam activam vel passivam quam habeant, eadem ratione potentiae sunt, quia scilicet est in eis vis principiata alicuius activae vel passivae.
Under the first member are included all active and passive, rational and irrational potencies, for whatever are said to be possible through their active or passive potency are potencies for the same reason, namely, because there is in them the originative force of something active or passive.
Peri.L12
Sub secundo autem membro comprehenduntur potentiae mathematicales et logicales. Mathematica potentia est, qua lineam posse dicimus in quadratum, et eo quod in semetipsam ducta quadratum constituit. Logica potentia est, qua duo termini coniungi absque contradictione in enunciatione possunt. Sub logica quoque potentia continetur quae ea ratione potentia dicitur, quia est.
Mathematical and logical potencies are included under the second member of this division. That by which a line can lead to a square we call a mathematical potency, for a line constitutes a square when protracted back to itself. That by which two terms can be joined in an enunciation without contradiction is a logical potency. Logical potency also comprises that which is called “potency” because it is.
Peri.L12
Hae vero merito aequivoce a primis potentiae dicuntur, eo quod istae nullam virtutem activam vel passivam praedicant; et quod possibile istis modis dicitur, non ea ratione possibile appellatur quia aliquis habeat virtutem ad hoc agendum vel patiendum, sicut in primis. Unde cum potentiae habentes se ad opposita sint activae vel passivae, istae quae aequivocae potestates dicuntur ad opposita non se habent. De his ergo loquens ait: quaedam vero potestates aequivocae sunt, et ideo ad opposita non se habent.
The latter [mathematical and logical potencies] are named from the former equivocally because they predicate no active or passive capacity; and what is said to be possible in these ways is not termed possible in virtue of having the capacity to do or undergo as in the first case. Hence, since the potencies related to opposites are active or passive, the ones that are called potentialities equivocally are not related to opposites. These, then, are the potencies he speaks of when he says, but some are called potentialities equivocally (23a6), and therefore they are not related to opposites.
Peri.L12
336. Deinde declarans qualis sit ista potestas aequivoce dicta, subdit divisionem usitatam possibilis per quam hoc scitur, dicens: possibile enim non uno modo dicitur, sed duobus.
To clarify the kind of potency that is called equivocal, he gives the usual division of the possible through which this is known. “Possible,” he says, is not said in one way, but in two.
Peri.L12
Et uno quidem modo dicitur possibile eo quod verum est ut in actu, idest ut actualiter est; ut, possibile est ambulare, quando ambulat iam: et omnino, idest universaliter possibile est esse, quoniam est actu iam quod possibile dicitur.
Something is said to be possible because it is true as in act, that is, inasmuch as it actually is (for example, it is possible to walk when one is already walking), and in general (or universally) that is said to be possible which is possible to be because it is already in act.
Peri.L12
Secundo modo autem possibile dicitur aliquid non ea ratione quia est actualiter, sed quia forsitan aget, idest quia potest agere; ut possibile est ambulare, quoniam ambulabit.
Something is said to be possible in the second way not because it actually is, but because it is about to act, that is, because it can act; for instance, it is possible for someone to walk because he is about to walk.
Peri.L12
Ubi advertendum est quod ex divisione bimembri possibilis divisionem supra positam potentiae declaravit a posteriori. Possibile enim a potentia dicitur: sub primo siquidem membro possibilis innuit potentias aequivoce; sub secundo autem potentias univoce, activas scilicet et passivas. Intendebat ergo quod quia possibile dupliciter dicitur, quod etiam potestas duplex est. Declaravit autem potestates aequivocas ex uno earum membro tantum, scilicet ex his quae dicuntur possibilia quia sunt, quia hoc sat erat suo proposito.
Notice here that by this two-membered division of the possible he makes the division of potency posited above evident a posteriori, for the possible is named from potency. Under the first member of the possible he signifies potencies equivocally; under the second, potencies univocally, that is, active and passive potencies. He means to show, then, that since “possible” is said in two ways, potentiality is also twofold. He explains equivocal potentialities in terms of only one member, namely, those that are called possible because they are, since this was sufficient for his purpose.
Peri.L12
337. Deinde cum dicit: et haec quidem etc., assignat differentiam inter utranque potentiam, et ait quod potentia haec ultimo dicta physica, est in solis illis rebus, quae sunt mobiles; illa autem est et in rebus mobilibus et immobilibus. Possibile siquidem a potentia dictum eo quod possit agere, non tamen agit, inveniri non potest absque mutabilitate eius, quod sic posse dicitur. Si enim nunc potest agere et non agit, si agere debet, oportet quod mutetur de otio ad operationem. Id autem quod possibile dicitur eo quod est, nullam mutabilitatem exigit in eo quod sic possibile dicitur. Esse namque in actu, quod talem possibilitatem fundat, invenitur et in rebus necessariis, et in immutabilibus, et in rebus mobilibus. Possibile ergo hoc, quod logicum vocatur, communius est illo quod physicum appellari solet.
When he says, this latter potentiality is only in that which is movable,(23a11), he specifies the difference between each potency. This last potency,1 he says, which is called physical potency, is only in things that are movable; but the former is in movable and immovable things. The possible that is named from the potency which can act, but is not yet acting, cannot be found without the mutability of that which is said to be possible in this way. For if that which can act now and is not acting should act, it is necessary that it be changed from rest to operation. On the other hand, that which is called possible because it is requires no mutability in that which is said to be possible in this way, for to be in act, which is the basis of such a possibility, is found in necessary things, in immutable things, and in mobile things. Therefore, the possible which is called logical is more common than the one we customarily call physical.
Peri.L12
338. Deinde subdit convenientiam inter utrunque possibile, dicens quod in utrisque potestatibus et possibilibus verum est non impossibile esse, scilicet, ipsum ambulare, quod iam actu ambulat seu agit, et quod iam ambulabile est; idest, in hoc conveniunt quod, sive dicatur possibile ex eo quod actu est, sive ex eo quod potest esse, de utroque verificatur non impossibile; et consequenter necessario verificatur possibile, quoniam ad non impossibile sequitur possibile. Hoc est secundum genus possibilis, respectu cuius Aristoteles supra dixit: et primum quidem etc., in quo non invenitur via ad utrunque oppositorum, hoc, inquam, est possibile quod iam actu est. Quod enim tali ratione possibile dicitur, iam determinatum est ex eo quod actu esse suppositum est. Non ergo possibile omne ad utrunque possibile est, sive loquamur de possibili physice, sive logice.
Then he shows that there is a correspondence between these possibles when he adds that not impossible to be is true of both of these potentialities and possibles. For instance, to walk is not impossible for that which is already walking in act (that is, acting), and it is not impossible for that which could now walk; that is, they agree in that not impossible is verified of both—of either what is said to be possible from the fact that it is in act or of what is said to be possible from the fact that it could be. Consequently, the necessary is verified as possible, for possible follows upon not impossible. The possible that is already in act is the second genus of the possible in which access is not found to both opposites, of which Aristotle spoke when he said, first of all this is not true of the potentialities (22b36). For that which is said to be possible because it is already in act is already determined, since it is supposed as being in act. Therefore, not every possible is the possible of alternatives, whether we speak of the physical possible or the logical.
Peri.L12
339. Deinde cum dicit: sic igitur possibile etc., applicat determinatam veritatem ad propositum.
When he says, so it is not true to say the latter possible (23a6), he applies the truth he has determined to what has been proposed.
Peri.L12
Et primo, concludendo ex dictis, declarat habitudinem utriusque possibilis ad necessarium, dicens quod hoc ergo possibile, scilicet physicum quod est in solis mobilibus, non est verum dicere et praedicare de necessario simpliciter: quia quod simpliciter necessarium est, non potest aliter esse. Possibile autem physicum potest sic et aliter esse, ut dictum est. Addit autem ly simpliciter, quoniam necessarium est multiplex. Quoddam enim est ad bene esse, quoddam ex suppositione: de quibus non est nostrum tractare, sed solummodo id insinuare. Quod ut praeservaret se ab illis modis necessarii qui non perfecte et omnino habent necessarii rationem, apposuit ly simpliciter. De tali enim necessario possibile physicum non verificatur. Alterum autem possibile logicum, quod in rebus immobilibus invenitur, verum est de illo enunciare, quoniam nihil necessitatis adimit. Et per hoc solvitur ratio inducta ad partem negativam quaestionis. Peccabat siquidem in hoc, quod ex necessario inferebat possibile ad utrunque quod convertitur in oppositam qualitatem.
First, by way of a conclusion from what has been said, he shows the relationship of each possible to the necessary. So, he says, it is not true to say and predicate this possible (namely physical) which is only in mobile things of the necessary simply, because what is necessary simply cannot be otherwise. The physical possible, however, can be thus and otherwise, as has been said. He adds simply because the necessary is manifold. There is the necessary for well-being and there is also the necessary from supposition, but it is not our business to treat these, only to indicate them. In order, then, to avoid the modes of the necessary that do not have the notion of the necessary perfectly and in every way, he adds simply. Now the physical possible is not verified of this kind of necessary,1 but it is true to enunciate the logical possible, the one found in immovable things, of the necessary, since it takes away nothing of the necessity. The argument introduced for the negative part of this question is destroyed by this. The error in that argument was the inference—by way of conversion into the opposite quality—of the possible to both alternatives from the necessary.
Peri.L12
340. Deinde respondet quaestioni formaliter intendens quod affirmativa pars quaestionis tenenda sit, quod scilicet ad necessarium sequitur possibile; et assignat causam. Quia ad partem subiectivam sequitur constructive suum totum universale; sed necessarium est pars subiectiva possibilis: quia possibile dividitur in logicum et physicum, et sub logico comprehenditur necessarium; ergo ad necessarium sequitur possibile. Unde dicit: quare, quoniam partem, scilicet subiectivam, suum totum universale sequitur, illud quod ex necessitate est, idest necessarium, tamquam partem subiectivam, consequitur posse esse, idest possibile, tamquam totum universale.
Then he replies to the question formally. He states that the affirmative part of the question must be held, namely, that the possible follows upon the necessary, and he assigns the cause. The whole universal follows constructively upon its subjective part; but the necessary is a subjective part of the possible, because the possible is divided into logical and physical and under the logical is comprehended the necessary; therefore, the possible follows upon the necessary. Hence he says, therefore, since the universal follows upon the part (23a15), that is, since the whole universal follows upon its subjective part, to be possible to be, that is, possible, as the whole universal, follows upon that which necessarily is, that is, necessary, as a subjective part.
Peri.L12
Sed non omnino, idest sed non ita quod omnis species possibilis sequatur; sicut ad hominem sequitur animal, sed non omnino, idest non secundum omnes suas partes subiectivas sequitur ad hominem: non enim valet: est homo, ergo est animal irrationale. Et per hoc confirmata ratione adducta ad partem affirmativam, expressius solvit rationem adductam ad partem negativam, quae peccabat secundum fallaciam consequentis, inferens ex necessario possibile, descendendo ad unam possibilis speciem, ut de se patet.
He adds: though not every kind of possible does (23a15), that is, not every species of the possible follows; just as animal follows upon man, but not in every way, namely, it does not follow upon man according to all its subjective parts, for it is not valid to say, “He is a man, therefore he is an irrational animal.” By this proof of the validity of the affirmative part, Aristotle has explicitly destroyed the reasoning adduced for the negative part, which, as is evident, erred according to the fallacy of the consequent in inferring the possible from the necessary by descending to one species of the possible.
Peri.L12
341. Deinde cum dicit: et est fortasse quidem etc., ordinat easdem modalium consequentias alio situ, praeponendo necessarium omnibus aliis modis.
When he says, indeed, the necessary and not necessary (23a18), he disposes the same consequences of modals in another arrangement, placing the necessary before all the other modes.
Peri.L12
Et circa hoc duo facit:
About this he does two things.
Peri.L12
primo, proponit quod intendit;
First, he proposes the order of modals;
Peri.L12
secundo, assignat causam dicti ordinis; ibi: manifestum est autem et cetera.
second, he assigns the cause of the order, at: it is evident, then, from what has been said (23a21; [342]).
Peri.L12
Dicit ergo: et est fortasse principium omnium enunciationum modalium vel esse vel non esse, idest, affirmativarum vel negativarum, necessarium et non necessarium. Et oportet considerare alia, scilicet, possibile contingere et impossibile esse, sicut horum, scilicet, necessarii et non necessarii, consequentia, hoc modo: consequentiae enunciationum modalium secundum quatuor ordines alio convenienti situ ab Aristotele positae et ordinatae: (Figura).
Indeed, he says, the necessary and not necessary may well be the principle of the “to be” or “not to be” of all modal enunciations (23a18), that is, the necessary and not necessary is the principle of affirmatives or negatives. And the others—the possible, contingent, and impossible to be—must be considered as consequent to these, namely, to the necessary and not necessary, as seen in the table of the consequents of modal enuniciations according to the four orders, posited and disposed by Aristotle in another appropriate arrangement.
Peri.L12
FIRST ORDERIt is necessary to beIt is not possible not to beIt is not contingent not to beIt is impossible not to be
Peri.L12
SECOND ORDERIt is necessary not to beIt is not possible to beIt is not contingent to beIt is impossible to be
Peri.L12
THIRD ORDERIt is not necessary to beIt is possible not to beIt is contingent not to beIt is not impossible not to be
Peri.L12
FOURTH ORDERIt is not necessary not to beIt is possible to beIt is contingent to beIt is not impossible to be
Peri.L12
Vides autem hic nihil immutatum, nisi quod necessariae quae ultimum locum tenebant, primum sortitae sunt. Quod vero dixit fortasse, non dubitantis, sed absque determinata ratione rem proponentis est.
Nothing is changed here except the enunciations predicating necessity. They have been allotted the first place, whereas in the former table they were placed last. When he says may well be, it is not because he is in any doubt, but because he is proposing this here without a determinate proof.
Peri.L12
342. Deinde cum dicit: manifestum est autem etc., intendit assignare causam dicti ordinis.
When he says, it is evident, then, from what has been said (23a21), he gives the cause of this order.
Peri.L12
Et primo, assignat causam, quare praeposuerit necessarium possibili tali ratione. Sempiternum est prius temporali; sed necessarium dicit sempiternitatem (quia dicit esse in actu, excludendo omnem mutabilitatem, et consequenter temporalitatem, quae sine motu non est imaginabilis), possibile autem dicit temporalitatem (quia non excludit quin possit esse et non esse); ergo necesse merito prius ponitur quam possibile.
First, he gives the reason for placing the necessary before the possible: the sempiternal is prior to the temporal; but “necessary” signifies sempiternal (because it signifies “to be in act,” excluding all mutability and consequently temporality, which is not imaginable without movement) and the possible signifies temporality (since it does not exclude the possibility of being and not being); therefore, the necessary is rightly placed before the possible.
Peri.L12
Unde dicit, proponendo minorem: manifestum est autem ex his quae dicta sunt etc., tractando de necessario: quoniam id quod ex necessitate est, secundum actum est totaliter, scilicet quia omnem excludit mutabilitatem et potentiam ad oppositum: si enim mutari posset in oppositum aliquo modo, iam non esset necessarium.
He proposes the minor of this argument when he says that it is evident, then, from what has been said (in treating the necessary) that which is necessarily is totally in act, since it excludes all mutability and potency to the opposite—for if it could be changed into the opposite in any way, then it would not be necessary.
Peri.L12
Deinde subdit maiorem per modum antecedentis conditionalis: quare si priora sunt sempiterna temporalibus et cetera.
Next, he gives the major, which is in the mode of an antecedent conditional: and if eternal things are prior to temporal (23a21).
Peri.L12
Ultimo ponit conclusionem: et quae actu sunt omnino, scilicet necessaria, priora sunt potestate, idest possibilibus, quae omnino actu esse non possunt, licet compatiantur.
Finally, he posits the conclusion: those that are wholly in act in every way (namely, the necessary) are prior to the potential (namely, to possibles), which do not have being in act wholly, although they are compatible with it.
Peri.L12
343. Deinde cum dicit: et hae quidem etc., assignat causam totius ordinis a se inter modales statuti, tali ratione. Universi triplex est gradus.
Then, when he says, some things are actualities without potentiality (23a23), he assigns the cause of the whole order established among modals. The grades of the universe are threefold.
Peri.L12
Quaedam sunt actu sine potestate, idest sine admixta potentia, ut primae substantiae, non illae quas in praesenti diximus primas, eo quod principaliter et maxime substent, sed illae quae sunt primae, quia omnium rerum sunt causae, intelligentiae scilicet.
Some things are in act without potentiality, that is, not combined with potency. These are the primary substances—not those we have called “first” in the present work because they principally and especially sustain, but those that are first because they are the causes of all things, namely, the Intelligences.
Peri.L12
Alia sunt actu cum possibilitate, ut omnia mobilia, quae secundum id quod habent de actu sunt priora natura seipsis secundum id quod habent de potentia, licet e contra sit, aspiciendo ordinem temporis. Sunt enim secundum id quod habent de potentia priora tempore seipsis secundum id quod habent de actu. Verbi gratia, Socrates prius secundum tempus poterat esse philosophus, deinde fuit actualiter philosophus. Potentia ergo praecedit actum secundum ordinem temporis in Socrate, ordine autem naturae, perfectionis et dignitatis e converso contingit. Prior enim secundum dignitatem, idest dignior et perfectior habebatur Socrates cum philosophus actualiter erat, quam cum philosophus esse poterat. Praeposterus est igitur ordo potentiae et actus in unomet, utroque ordine, scilicet, naturae et temporis attento.
In others, act is accompanied with possibility, as is the case with all mobile things, which, according to what they have of act, are prior in nature to themselves according to what they have of potency, although the contrary is the case in regard to the order of time. According to what they have of potency, they are prior in time to themselves according to what they have of act. For example, according to time, Socrates first was able to be a philosopher, then he actually was a philosopher. In Socrates, therefore, potency precedes act according to the order of time. The converse is the case, however, in the order of nature, perfection, and dignity, for when he actually was a philosopher, Socrates was regarded as prior according to dignity, that is, more worthy and more perfect than when he was potentially a philosopher. Hence, when we consider each order, that is, nature and time, in one and the same thing, the order of potency and act is reversed.
Peri.L12
Alia vero nunquam sunt actu sed potestate tantum, ut motus, tempus, infinita divisio magnitudinis, et infinita augmentatio numeri. Haec enim, ut IX Metaphys. dicitur, nunquam exeunt in actum, quoniam eorum rationi repugnat. Nunquam enim aliquid horum ita est quin aliquid eius expectetur, et consequenter nunquam esse potest nisi in potentia. Sed de his alio tractandum est loco.
Others never are in act but are only in potency, such as motion, time, the infinite division of magnitude, and the infinite augmentation of number. These, as is said in Metaphysics 9.6 (1048b9–17), never terminate in act, for it is repugnant to their nature. None of them is ever such that something of it is not expected, and consequently they can only be in potency. These, however, must be treated in another place.
Peri.L12
344. Nunc haec ideo dicta sint ut, inspecto ordine universi, appareat quod illum imitati sumus in nostro ordine.
This has been said so that, once the order of the universe has been seen, it would be clear that we were imitating it in our present ordering.
Peri.L12
Posuimus siquidem primo necessarium, quod sonat actu esse sine potestate seu mutabilitate, imitando primum gradum universi.
The necessary, which signifies “to be in act” without potentiality or mutability, has been placed first, in imitation of the first grade of the universe.
Peri.L12
Locavimus secundo loco possibile et contingens, quorum utrunque sonat actum cum possibilitate, et sic servatur conformitas ad secundum gradum universi. Praeposuimus autem possibile et non contingens, quia possibile respicit actum, contingens autem secundum vim nominis respicit defectum causae, qui ad potentiam pertinet: defectus enim potentiam sequitur; et ex hoc conforme est secundae parti universi, in qua actus est prior potentia secundum naturam, licet non secundum tempus.
We have put the possible and contingent, both of which signify act with possibility, in the second place in conformity with the second grade of the universe. The possible has been placed before the contingent because the possible relates to act, while the contingent, as the force of the name suggests, relates to the defect of a cause, which pertains to potency, for defect follows upon potency. The order of these is similar to the order in the second part of the universe, where act is prior to potency according to nature, though not according to time.
Peri.L12
Ultimum autem locum impossibili reservavimus, eo quod sonat nunquam fore, sicut et ultima universi pars dicta est illa, quae nunquam actu est.
We have reserved the last place for the impossible because it signifies what never will be, just as the last part of the universe is said to be that which is never in act.
Peri.L12
Pulcherrimus igitur ordo statutus est, quando divinus est observatus.
Thus, a beautifully proportioned order is established when the divine is observed.
Peri.L12
345. Quia autem suppositae modalium consequentiae nil aliud sunt quam aequipollentiae earum, quae ob varium negationis situm, qualitatem, vel quantitatem, vel utranque mutantis, fiunt; ideo ad completam notitiam consequentium se modalium, de earum qualitate et quantitate pauca admodum necessaria dicenda sunt. Quoniam igitur natura totius ex partium naturis consurgit, sciendum est quod subiectum enunciationis modalis et dicit esse vel non esse, et est dictum unicum, et continet in se subiectum dicti; praedicatum autem modalis enunciationis, modus scilicet, et totale praedicatum est (quia explicite vel implicite verbum continet, quod est semper nota eorum quae de altero praedicantur: propter quod Aristoteles dixit quod modus est ipsa appositio), et continet in se vim distributivam secundum partes temporis. Necessarium enim et impossibile distribuunt in omne tempus vel simpliciter vel tale; possibile autem et contingens pro aliquo tempore in communi.
Since the consequents of modals (namely, those placed under each other) are their equivalents in meaning, and these are produced by the varying position of the negation changing the quality or quantity or both, a few things must be said about their quality and quantity to complete our knowledge of them. The nature of the whole arises from the parts, and therefore we should note the following things about the parts of the modal enunciation. The subject of the modal enunciation asserts to be or not to be, and is a singular dictum, and contains in itself the subject of the dictum. The predicate of a modal enunciation, namely, the mode, is the total predicate (since it explicitly or implicitly contains the verb, which is always a sign of something predicated of another, for which reason Aristotle says that the mode is a determining addition), and contains in itself distributive force according to the parts of time. The necessary and impossible distribute in all time either simply or in a limited way; the possible and contingent distribute according to some time commonly.
Peri.L12
346. Nascitur autem ex his quinque conditionibus duplex in qualibet modali qualitas, et triplex quantitas.
As a consequence of these five conditions there is a twofold quality and a threefold quantity in any modal.
Peri.L12
Ex eo enim quod tam subiectum quam praedicatum modalis verbum in se habet, duplex qualitas fit, quarum altera vocatur qualitas dicti, altera qualitas modi. Unde et supra dictum est aliquam esse affirmativam de modo et non de dicto, et e converso.
The twofold quality results from the fact that both the subject and the predicate of a modal have a verb in them. One of these is called the quality of the dictum, the other the quality of the mode. This is why it was said above that there is an enunciation which is affirmative of mode and not of dictum, and conversely.
Peri.L12
Ex eo vero quod subiectum modalis continet in se subiectum dicti, una quantitas consurgit, quae vocatur quantitas subiecti dicti: et haec distinguitur in universalem, particularem et singularem, sicut et quantitas illarum de inesse. Possumus enim dicere, Socratem, quemdam hominem, vel omnem hominem, vel nullum hominem, possibile est currere.
Of the threefold quantity of a modal enunciation, one arises from the fact that the subject of the modal contains in it the subject of the dictum. This is called the quantity of the subject of the dictum, and is distinguished into universal, particular, and singular, as in the case of the quantity of an absolute enunciation. For we can say that it is possible that “Socrates,” “some man,” “every man,” or “no man” run.
Peri.L12
Ex eo autem quod subiectum unius modalis dictum unum est, consurgit alia quantitas, vocata quantitas dicti; et haec unica est singularitas: secundum omne enim dictum cuiusque modalis singulare est istius universalis, scilicet dictum. Quod ex eo liquet quod cum dicimus, hominem esse album est possibile, exponitur sic, hoc dictum, hominem esse album, est possibile. Hoc dictum autem singulare est, sicut et, hic homo. Propterea et dicitur quod omnis modalis est singularis quoad dictum, licet quoad subiectum dicti sit universalis vel particularis.
The second quantity is that of the dictum, which arises from the fact that the subject of one modal is one dictum. This is a unique singularity, for every dictum of a modal is the singular of that universal, namely, the dictum. “That man be white is possible” means that this dictum, “that man be white,” is possible. “This dictum” is singular in quantity, just as “this man” is. Hence, every modal is singular with respect to dictum, although with respect to the subject of the dictum it is universal or particular.
Peri.L12
Ex eo autem quod praedicatum modalis, modus scilicet, vim distributivam habet, alia quantitas consurgit vocata quantitas modi seu modalis; et haec distinguitur in universalem et particularem.
The third quantity is that of the mode, or modal quantity, which arises from the fact that the predicate of the modal, which is the mode, has distributive force. This is distinguished into universal and particular.
Peri.L12
347. Ubi diligenter duo attendenda sunt.
Now, there are two things about modal enunciations that must be carefully noted.
Peri.L12
Primum est quod hoc est singulare in modalibus, quod praedicatum simpliciter quantificat propositionem modalem, sicut et simpliciter qualificat. Sicut enim illa est simpliciter affirmativa, in qua modus affirmatur, et illa negativa, in qua modus negatur; ita illa est simpliciter universalis cuius modus est universalis, et illa particularis cuius modus est particularis. Et hoc quia modalis modi naturam sequitur.
The first—which is peculiar to modals—is that the predicate quantifies the modal proposition simply, as it also qualifies it simply. For just as the modal enunciation in which the mode is affirmed is affirmative simply, and negative when the mode is negated, so the modal enunciation in which the mode is universal is universal simply and particular in which the mode is particular. The reason for this is that the modal follows the nature of the mode.
Peri.L12
Secundum attendendum (quod est causa istius primi) est, quod praedicatum modalis, scilicet modus, non habet solam habitudinem praedicati respectu sui subiecti, scilicet esse et non esse, sed habitudinem syncategorematis distributivi, sed non secundum quantitatem partium subiectivarum ipsius subiecti, sed secundum quantitatem partium temporis eiusdem. Et merito. Sicut enim quia subiecti enunciationis de inesse propria quantitas est penes divisionem vel indivisionem ipsius subiecti (quia est nomen quod significat per modum substantiae, cuius quantitas est per divisionem continui: ideo signum quantificans in illis distribuit secundum partes subiectivas), ita quia subiecti enunciationis modalis propria quantitas est tempus (quia est verbum quod significat per modum motus, cuius propria quantitas est tempus), ideo modus quantificans distribuit ipsum suum subiectum, scilicet, esse vel non esse, secundum partes temporis. Unde subtiliter inspicienti apparebit quod quantitas ista modalis proprii subiecti modalis enunciationis quantitas est, scilicet, ipsius esse vel non esse.
The second thing to be noted (which is the cause of the first) is that the predicate of a modal, which is the mode, not only has the relationship of a predicate to its subject (that is, to “to be” and “not to be”), but also has the relationship to the subject of a distributive syncategorematic term, which has the effect of distributing the subject not according to the quantity of its subjective parts, but according to the quantity of the parts of its time. And rightly so, for just as the proper quantity of the subject of an absolute enunciation varies according to the division or lack of division of its subject (since the subject is a name which signifies in the mode of substance, whose quantity is from the division of the continuous, and therefore the quantifying sign distributes according to the subjective parts), so, because the proper quantity of the subject of a modal enunciation is time (since the subject is a verb, which signifies in the mode of movement, whose proper quantity is time), the quantifying mode distributes the subject, namely, “to be” or “not to be,” according to the parts of time. Hence, we arrive at the subtle point that the quantity of the modal is the quantity of the proper subject of the modal enunciation, namely, of “to be” or “not to be.”
Peri.L12
Ita quod illa modalis est simpliciter universalis, cuius proprium subiectum distribuitur pro omni tempore: vel simpliciter, ut, hominem esse animal est necessarium vel impossibile; vel accepto, ut, hominem currere hodie, vel, dum currit, est necessarium vel impossibile. Illa vero est particularis, in qua non pro omni, sed aliquo tempore distributio fit in communi tantum; ut, hominem esse animal, est possibile vel contingens. Est ergo et ista modalis quantitas subiecti sui passio (sicut et universaliter quantitas se tenet ex parte materiae), sed derivatur a modo, non in quantum praedicatum est (quod, ut sic, tenetur formaliter), sed in quantum syncategorematis officio fungitur, quod habet ex eo quod proprie modus est.
Therefore, a modal enunciation is universal simply when the proper subject is distributed throughout all time, either simply, as in “that man is an animal is necessary or impossible,” or taken in a limited way, as in “that man is running today or until he is running is necessary or impossible.” A modal enunciation is particular in which “to be” or “not to be” is distributed not throughout all time, but commonly throughout some time, as in “that man is an animal is possible or contingent.” This modal quantity is therefore also a property of its subject (in that quantity universally comes from the matter) but is derived from the mode not insofar as it is a predicate (because, as such, it is understood formally), but insofar as it performs a syncategorematic function, which it has in virtue of the fact that it is properly a mode.
Peri.L12
348. Sunt igitur modalium (de propria earum quantitate loquendo) aliae universales affirmativae, ut illae de necessario, quia distribuunt ad semper esse; aliae universales negativae, ut illae de impossibili, quia distribuunt ad nunquam esse; aliae particulares affirmativae, ut illae de possibili et contingenti, quia distribuunt utrunque ad aliquando esse; aliae particulares negativae, ut illae de non necesse et non impossibili, quia distribuunt ad aliquando non esse: sicut in illis de inesse, omnis, nullus, quidam, non omnis, non nullus, similem faciunt diversitatem. Et quia, ut dictum est, haec quantitas modalium est inquantum modales sunt, et de his, inquantum huiusmodi, praesens tractatus fit ab Aristotele; idcirco aequipollentiae, seu consequentiae earum, ordinatae sunt negationis vario situ, quemadmodum aequipollentiae illarum de inesse: ut scilicet, negatio praeposita modo faciat aequipollere suae contradictoriae; negatio autem modo postposita, posita autem dicti verbo, suae aequipollere contrariae facit; praeposita vero et postposita suae subalternae, ut videre potes in consequentiarum figura ultimo ab Aristotele formata. In qua, tali praeformata oppositionum figura, clare videbis omnes se mutuo consequentes, secundum alteram trium regularum aequipollere, et consequenter, totum primum ordinem secundo contrarium, tertio contradictorium, quarto vero subalternum. (Figura).
Therefore, with respect to their proper quantity, some modals are universal affirmatives, namely, those of the necessary, because they distribute “to be” to all time. Others are universal negatives, namely, those of the impossible because they distribute “to be” to no time. Still others are particular affirmatives, namely, those signifying the possible and contingent, for both of these distribute “to be” to some time. Finally, there are particular negatives, namely, those of the not necessary and not impossible, for they distribute “not to be” to some time. This is similar to the diversity in absolute enunciations from the use of “every,” “no,” “some,” “not all,” and “not none.” Now, since this quantity belongs to modals insofar as they are modals, as has been said, and since Aristotle is now considering them in this particular respect, the modal enunciations that are equivalent, namely, their consequents, are ordered by the different location of the negation, as is the case with absolute enunciations that are equivalent. A negative placed before the mode makes an enunciation equivalent to its contradictory; placed after the mode, namely, with the verb of the dictum, makes it equivalent to its contrary; placed before and after the mode makes it equivalent to its subaltern, as you can see in the last table of consequents given by Aristotle. In that table of oppositions, you see all the mutual consequents, according to one of the three rules for making enunciations equivalent. Consequently, the whole first order of equivalent enunciations is contrary to the second, contradictory to the third, and the fourth is subalternated to it. [insert figure]

Contrariety of Opinions in the Mind Is Constituted by an Opposition of the True and the False
Peri.L13
Utrum autem contraria est affirmatio negationi, aut affirmatio affirmationi et oratio orationi, quae dicit, quod omnis homo iustus est, ei quae est, nullus homo iustus est; aut, omnis homo iustus est, ei quae est, omnis homo iniustus est; ut, Callias iustus est, Callias iustus non est, Callias iniustus est; utra harum contraria est?
23a27. There is a question as to whether the contrary of an affirmation is a negation, or whether the contrary of an affirmation is another affirmation; and in the case of speech whether the one saying that no man is just is contrary to the one saying that every man is just, or is the one saying that every man is unjust contrary to the one saying that every man is just. For example, which of these are contraries: “Callias is just,” “Callias is not just,” “Callias is unjust”?
Peri.L13
Nam sona, quae sunt in voce, sequuntur ea, quae sunt in intellectu, illic autem contraria est opinio contrarii, ut quod, omnis homo iustus est, ei quae est, omnis homo iniustus est, et etiam in his, quae sunt in voce, affirmationibus, necesse est similiter se se habere. Quod si neque illic contrarii opinatio contraria est, nec affirmatio affirmationi contraria erit; sed ea quae dicta est negatio. Quare considerandum est quae opinio vera opinioni falsae contraria est, utrum negationis, an ea, quae contrarium esse opinatur.
23a32. For if those things that are in vocal sound are determined by those in the intellect, and if in the intellect that opinion is contrary which is about a contrary—for instance, the contrary of “every man is just” is “every man is unjust”—the case must be the same with respect to spoken affirmations. But if in the intellect the contrary opinion is not one which is about a contrary, then in speech the affirmation will not be contrary to the affirmation, but the negation will be. We must therefore consider which false opinion is contrary to a true opinion, whether it is a negation of the true opinion or the opinion affirming a contrary.
Peri.L13
Dico autem hoc modo. Est quaedam opinatio vera boni, quod bonum est; alia vero, quod non bonum, est falsa; alia vero, quod malum: utra harum contraria verae? et si est una, secundum quamnam contraria est?
What I mean is this: there is a true opinion of that which is good, that it is good, and a false opinion, that it is not good, and another kind, that it is evil. Of the latter two, which one is contrary to the true opinion? And if they are one and the same, which one is the contrary?
Peri.L13
Nam arbitrari contrarias opiniones definiri, eo quod contrariorum sunt, falsum est: boni enim, quod bonum est, et mali, quod malum est, eadem fortasse opinio est et vera, sive plures, sive una sit. Sunt autem ista contraria. Sed non eo quod contrariorum sint contraria sunt, sed magis eo quod contrarie.
23b2. It is false, of course, to suppose that opinions are to be defined as contrary because they are about contraries; for the opinion of that which is good, that it is good, and of that which is evil, that it is evil, are probably the same, and, whether they are many or one are true. Yet good and evil are contraries. However, opinions are not contraries because they are about contraries; rather, they are contrary because they are related contrarily.
Peri.L13
Si ergo est boni quidem, quod est bonum, opinio, alia autem quod non est bonum: est vero aliquid aliud quod non est, neque potest esse: aliarum quidem nulla ponenda est, neque quaecumque esse, quod non est, opinantur, neque quaecunque non esse quod est (infinitae enim utraeque sunt, et quae esse opinantur quod non est, et quae non esse quod est).
23b7. Now, if there is the opinion of that which is good, that it is good, and the opinion that it is not good, and there are other opinions that something that does not belong and could not possibly belong to the good belongs to the good, none of the latter should be posited as the contrary, neither those purporting that what does not belong to the good belongs to it nor those purporting that what belongs to the good does not belong to it, for the opinions that that belongs which does not belong and the opinions that that does not belong which does are infinite.
Peri.L13
349. Postquam determinatum est de enunciatione secundum quod diversificatur tam ex additione facta ad terminos, quam ad compositionem eius, hic secundum divisionem a s. Thoma in principio huius secundi factam, intendit Aristoteles tractare quandam quaestionem circa oppositiones enunciationum provenientes ex eo quod additur aliquid simplici enunciationi.
Now that he has treated the enunciation as it is diversified by an addition made to the terms and by an addition made to its composition (which is the division of the text made by St. Thomas at the beginning of the second book), Aristotle takes up another question about oppositions of enunciations. This question concerns the oppositions that result from something added to the simple enunciation.
Peri.L13
Et circa hoc quatuor facit:
About this he does four things.
Peri.L13
primo, movet quaestionem;
First, he asks the question;
Peri.L13
secundo, declarat quod haec quaestio dependet ab una alia quaestione praetractanda; ibi: nam si ea, quae sunt in voce etc.;
second, he shows that this question depends upon another, which must be treated first, at: for if those things that are in vocal sound are determined by those in the intellect (23a32; [353];
Peri.L13
tertio, determinat illam aliam quaestionem; ibi: nam arbitrari etc.;
third, he settles the latter question, at: it is false, course, to suppose that opinions are to be defined (23b2; [356]);
Peri.L13
quarto, redit ad respondendum quaestioni primo motae; ibi: quare si in opinione et cetera.
fourth, he replies to the first question, at: if, therefore, this is the case with respect to opinion (24b1; [374]).
Peri.L13
Quaestio quam movere intendit est: utrum affirmativae enunciationi contraria sit negatio eiusdem praedicati, an affirmatio de praedicato contrario seu privativo? Unde dicit: utrum contraria est affirmatio negationi contradictoriae, scilicet, et universaliter oratio affirmativa orationi negativae; ut, affirmativa oratio quae dicit, omnis homo est iustus, illi contraria sit orationi negativae, nullus homo est iustus, aut illi, omnis homo est iniustus, quae est affirmativa de praedicato privativo? Et similiter ista affirmatio, Callias est iustus, est ne contraria illi contradictoriae negationi, Callias non est iustus, aut illi, Callias est iniustus, quae est affirmativa de praedicato privativo?
The first question he raises is this: is the contrary of an affirmative enunciation the negation of the same predicate or the affirmation of a contrary or privative predicate? Hence he says, there is a question as to whether the contrary of an affirmation is the contradictory negation (23a27), and universally, whether affirmative speech is contrary to negative speech. For instance, is affirmative speech which says every man is just contrary to negative speech which says no man is just, or to the affirmative of the privative predicate, every man is unjust? And similarly, is the affirmation Callias is just contrary to the contradictory negation, Callias is not just, or is it contrary to Callias is unjust, the affirmative of the privative predicate?
Peri.L13
350. Ad evidentiam tituli huius quaestionis, quia hactenus indiscusse ab aliis est relictus, considerare oportet quod cum in enunciatione sint duo, scilicet ipsa enunciatio seu significatio et modus enunciandi seu significandi, duplex inter enunciationes fieri potest oppositio, una ratione ipsius enunciationis, altera ratione modi enunciandi.
Since this question has not been discussed by others, we must begin by noting that there are two things in an enunciation, namely, the enunciation itself (or the signification), and the mode of enunciating or signifying. Hence, a twofold opposition can be made between enunciations, one by reason of the enunciation itself, the other by reason of the mode of enunciating.
Peri.L13
Si modos enunciandi attendimus, duas species oppositionis in latitudine enunciationum inveniemus, contrarietatem scilicet et contradictionem. Divisae enim superius sunt enunciationes oppositae in contrarias et contradictorias.
If we consider the modes of enunciating, we find two species of opposition among enunciations, namely, contrariety and contradiction. This point was made earlier when opposed enunciations were divided into contraries and contradictories.
Peri.L13
Contradictio inter enunciationes ratione modi enunciandi est quando idem praedicatur de eodem subiecto contradictorio modo enunciandi; ut sicut unum contradictorium nil ponit, sed alterum tantum destruit, ita una enunciatio nil asserit, sed id tantum quod altera enunciabat destruit. Huiusmodi autem sunt omnes quae contradictoriae vocantur, scilicet, omnis homo est iustus, non omnis homo est iustus, Socrates est iustus, Socrates non est iustus, ut de se patet. Et ex hoc provenit quod non possunt simul verae aut falsae esse, sicut nec duo contradictoria.
There is contradiction by reason of mode of enunciating when the same thing is predicated of the same subject in a contradictory mode; so that just as one of a pair of contradictories posits nothing but only destroys the other, so one enunciation asserts nothing, but only destroys what the other was enunciating. All enunciations that are called contradictories are of this kind; for instance, "every man is just, not every man is just"; "Socrates is just, Socrates is not just." It follows from this that they cannot be at once true or false, just as two contradictories cannot be at once.
Peri.L13
Contrarietas vero inter enunciationes ratione modi enunciandi est quando idem praedicatur de eodem subiecto contrario modo enunciandi; ut sicut unum contrariorum ponit materiam sibi et reliquo communem in extrema distantia sub illo genere, ut patet de albo et nigro, ita una enunciatio ponit subiectum commune sibi et suae oppositae in extrema distantia sub illo praedicato. Huiusmodi quoque sunt omnes illae quae contrariae in figura appellantur, scilicet, omnis homo est iustus, omnis homo non est iustus. Hae enim faciunt subiectum, scilicet hominem, maxime distare sub iustitia, dum illa enunciat iustitiam inesse homini, non quocunque modo, sed universaliter; ista autem enunciat iustitiam abesse homini, non qualitercunque, sed universaliter. Maior enim distantia esse non potest quam ea, quae est inter totam universitatem habere aliquid et nullum de universitate habere illud. Et ex hoc provenit quod non possunt esse simul verae, sicut nec contraria possunt eidem simul inesse; et quod possunt esse simul falsae, sicut et contraria simul non inesse eidem possunt.
There is contrariety between enunciations by reason of mode of enunciating when the same thing is predicated of the same subject in a contrary mode of enunciating; so that just as one of a pair of contraries posits matter common to itself and to the other which is at the extreme distance under that genus—as is evident, for instance, in white and black—so one enunciation posits a subject common to itself and its opposite at the extreme distance under that predicate. All the enunciations in the diagram that are called contrary are of this kind, such as "every man is just, no man is just." These make the subject “man” distant to the greatest degree possible under justice, one enunciating justice to be in man not in just any way, but universally, the other enunciating justice to be absent from man, not in just any way, but universally. For no distance can be greater than the distance between the total number of things having something and none of the total number of things having that thing. It follows that contrary enunciations cannot be at once true, just as contraries cannot be in the same thing at once. They can, however, be false at the same time, just as it is possible that contraries not be in the same thing at the same time.
Peri.L13
Si vero ipsam enunciationem sive eius significationem attendamus secundum unam tantum oppositionis speciem, in tota latitudine enunciationum reperiemus contrarietatem, scilicet secundum veritatem et falsitatem: quia duarum enunciationum significationes entia positiva sunt, ac per hoc neque contradictorie neque privative opponi possunt, quia utriusque oppositionis alterum extremum est formaliter non ens. Et cum nec relative opponantur, ut clarum est, restat ut nonnisi contrarie opponi possunt.
If we consider the enunciation itself (namely, its signification) according to only one species of opposition, we will find in the whole range of enunciations an opposition of contrariety, namely, an opposition according to truth and falsity. The reason for this is that the significations of two enunciations are positive, and accordingly cannot be opposed either contradictorily or privatively because the other extreme of both of these oppositions is formally non-being. And since significations are not opposed relatively, as is evident, the only way they can be opposed is contrarily.
Peri.L13
351. Consistit autem ista contrarietas in hoc quod duarum enunciationum altera alteram non compatitur vel in veritate vel in falsitate, praesuppositis semper conditionibus contrariorum, scilicet quod fiant circa idem et in eodem tempore. Patere quoque potest talem oppositionem esse contrarietatem ex natura conceptionum animae componentis et dividentis, quarum singulae sunt enunciationes. Conceptiones siquidem animae adaequatae nullo alio modo opponuntur conceptionibus inadaequatis nisi contrarie, et ipsae conceptiones inadaequatae, si se mutuo expellunt, contrariae quoque dicuntur. Unde verum et falsum, contrarie opponi probatur a s. Thoma in I parte, qu. 17. Sicut ergo hic, ita et in enunciationibus ipsae significationes adaequatae contrarie opponuntur inadaequatis, idest verae falsis; et ipsae inadaequatae, idest falsae, contrarie quoque opponuntur inter se, si contingat quod se non compatiantur, salvis semper contrariorum conditionibus. Est igitur in enunciationibus duplex contrarietas, una ratione modi, altera ratione significationis, et unica contradictio, scilicet ratione modi. Et, ut confusio vitetur, prima contrarietas vocetur contrarietas modalis, secunda contrarietas formalis. Contradictio autem non ad confusionis vitationem quia unica est, sed ad proprietatis expressionem contradictio modalis vocari potest. Invenitur autem contrarietas formalis enunciationum inter omnes contradictorias, quia contradictoriarum altera alteram semper excludit; et inter omnes contrarias modaliter quoad veritatem, quia non possunt esse simul verae, licet non inveniatur inter omnes quoad falsitatem, quia possunt esse simul falsae.
The contrariety spoken of here consists in this: of two enunciations, one is not compatible with the other either in truth or falsity—presupposing always the conditions for contraries, that they are about the same thing and at once. It can be shown that such opposition is contrariety from the nature of the conceptions of the soul when composing and dividing, each of which is an enunciation. Adequate conceptions of the soul are opposed to inadequate conceptions only contrarily, and inadequate conceptions, if each cancels the other, are also called contraries. It is from this that St. Thomas proves, in ST I, Q. 17, that the true and false are contrarily opposed. Therefore, as in the conceptions of the soul, so in enunciations, adequate significations are contrarily opposed to inadequate (that is, true to false); and the inadequate (or the false) are also contrarily opposed among themselves if it happens that they are not compatible, supposing always the conditions for contraries. There is, therefore, in enunciations a twofold contrariety, one by reason of mode, the other by reason of signification, and only one contradiction, that by reason of mode. To avoid confusion, let us call the first contrariety modal and the second formal. We may call contradiction modal, not to avoid confusion (since it is unique), but for propriety of expression. Formal contrariety is found between all contradictory enunciations, since one contradictory always excludes the other. It is also found between all modally contrary enunciations in regard to truth, since they cannot be at once true. However, it is not found between the latter in regard to falsity, since they can be at once false.
Peri.L13
352. Quia igitur Aristoteles in hac quaestione loquitur de contrarietate enunciationum quae se extendit ad contrarias modaliter, et contradictorias, ut patet in principio et in fine quaestionis (in principio quidem, quia proponit utrasque contradictorias dicens: affirmatio negationi etc.; et contrarias modaliter dicens: et oratio orationi etc., unde et exempla utrarunque statim subdit, ut patet in littera. In fine vero, quia ibi expresse quam conclusit esse contrariam affirmativae universali verae dividit, in contrariam modaliter universalem negativam, scilicet, et contradictoriam: quae divisio falsitate non careret, nisi conclusisset contrariam formaliter, ut de se patet), quia, inquam, sic accipit contrarietatem, ideo de contrarietate formali enunciationum quaestio intelligenda est. Et est quaestio valde subtilis, necessaria et adhuc nullo modo superius tacta.
Aristotle in this question is speaking of the contrariety of enunciations that extends to contraries modally and to contradictories. This is evident from what he says in the beginning and at the end of the question. In the beginning, he proposes both contradictories when he says, whether the contrary of an affirmation is a negation (23a27); and contraries modally, when he says, or whether the contrary of an affirmation is another affirmation. It is evident, too, from the examples immediately added. At the end, he explicitly divides what he has concluded to be contrary to a true universal affirmative, into the modally contrary universal negative and the contradictory. It is clear at once that this division would be false unless it comprised the contrary formally. Since he takes contrariety in this way, the question must be understood with respect to formal contrariety of enunciations. This is a very subtle question which must be treated but has not been thus far.
Peri.L13
Est igitur titulus quaestionis; utrum affirmativae verae contraria formaliter sit negativa falsa eiusdem praedicati, aut affirmativa falsa de praedicato, vel contrario? Et sic patet quis sit sensus tituli, et quare non movet quaestionem de quacunque alia oppositione enunciationum (quia scilicet nulla alia in eis formaliter invenitur), et quod accipit contrarietatem proprie et strictissime, licet talis contrarietas inveniatur inter contradictorias modaliter et contrarias modaliter. Dictum vero fuit a s. Thoma provenire hanc dubitationem ex eo quod additur aliquid simplici enunciationi, quia si tantum simplices, idest, de secundo adiacente enunciationes attendantur, non habet haec quaestio radicem. Quia autem simplici enunciationi, idest subiecto et verbo substantivo, additur aliquid, scilicet praedicatum, nascitur dubitatio circa oppositionem, an illud additum in contrariis debeat esse illudmet praedicatum, negatione apposita verbo, an debeat esse praedicatum contrarium seu privativum, absque negatione praeposita verbo.
The question, therefore, is this: whether the formal contrary of the true affirmative is the false negative of the same predicate or the false affirmative of the privative predicate (that is, of the contrary)? The meaning of the question is now clear, and it is evident why he does not ask about any other oppositions of enunciations—no other opposition is found in them formally. It is also evident that he is taking contrariety properly and strictly, notwithstanding the fact that such contrariety is found among contradictories modally and contraries modally. St. Thomas has already pointed out that this question arises from the fact that something is added to the simple enunciation, for as far as simple enunciations are concerned (that is, those with only a second determinant), there is no occasion for the question. When, however, something is added, namely a predicate, to the simple enunciation, that is, to the subject and the substantive verb, the question arises as to whether what ought to be added in contrary enunciations is the selfsame predicate with a negation added to the verb or a contrary (that is, privative) predicate without a negation added to the verb.
Peri.L13
353. Deinde cum dicit: nam si ea etc., declarat unde sumenda sit decisio huius quaestionis.
When Aristotle says, for if those things that are in vocal sound (23a32), he shows where we have to begin in order to settle this question.
Peri.L13
Et duo facit:
And he does two things.
Peri.L13
quia primo declarat quod haec quaestio dependet ex una alia quaestione, ex illa scilicet: utrum opinio, idest conceptio animae, in secunda operatione intellectus, vera, contraria sit opinioni falsae negativae eiusdem praedicati, an falsae affirmativae contrarii sive privativi.
First, he shows that the question depends on another question, namely, whether a true opinion (that is, a conception of the soul in the second operation of the intellect) is contrary to a false negative opinion of the same predicate, or to a false affirmative of the contrary (or privative) predicate.
Peri.L13
Et assignat causam, quare illa quaestio dependet ex ista, quia scilicet enunciationes vocales sequuntur mentales, ut effectus adaequati causas proprias, et ut significata signa adaequata, et consequenter similis est in hoc utraque natura.
Then he gives the reason why the former question depends on this. Vocal enunciations follow upon mental as adequate effects upon proper causes and as the signified upon adequate signs. So, in this the nature of each is similar.
Peri.L13
Unde inchoans ab hac causa ait: nam si ea quae sunt in voce sequuntur ea, quae sunt in anima, ut dictum est in principio I libri, et illic, idest in anima, opinio contrarii praedicati circa idem subiectum est contraria illi alteri, quae affirmat reliquum contrarium de eodem (cuiusmodi sunt istae mentales enunciationes, omnis homo est iustus, omnis homo est iniustus); si ita inquam est, etiam et in his affirmationibus quae sunt in voce, idest vocaliter sumptis, necesse est similiter se habere, ut scilicet sint contrariae duae affirmativae de eodem subiecto et praedicatis contrariis. Quod si neque illic, idest in anima, opinatio contrarii praedicati, contrarietatem inter mentales enunciationes constituit, nec affirmatio vocalis affirmationi vocali contraria erit de contrario praedicato, sed magis affirmationi contraria erit negatio eiusdem praedicati.
He begins, then, with the reason for this dependence (23a32): for if those things that are in vocal sound are determined by those in the intellect (as was said in the beginning of the first book) and if those opinions are contrary in the soul which affirm contrary predicates about the same subject, (for example, the mental enunciations, every man is just, every man is unjust), then in affirmations that are in vocal sound, the case must be the same. The contraries will be two affirmatives about the same subject with contrary predicates. But if in the soul this is not the case—namely, that opinions with contrary predicates constitute contrariety in mental enunciations—then the contrary of a vocal affirmation will not be a vocal affirmation with a contrary predicate. Rather, the contrary of an affirmation will be the negation of the same predicate.
Peri.L13
354. Dependet ergo mota quaestio ex ista alia sicut effectus ex causa. Propterea et concludendo addit secundum, quod scilicet de hac quaestione prius tractandum est, ut ex causa cognita effectus innotescat dicens: quare considerandum est, opinio vera cui opinioni falsae contraria est: utrum negationi falsae an certe ei affirmationi falsae, quae contrarium esse opinatur. Et ut exemplariter proponatur, dico hoc modo: sunt tres opiniones de bono, puta vita: quaedam enim est ipsius boni opinio vera, quoniam bonum est, puta, quod vita sit bona; alia vero falsa negativa, scilicet, quoniam bonum non est, puta, quod vita non sit bona; alia item falsa affirmativa contrarii, scilicet, quoniam malum est, puta, quod vita sit mala. Quaeritur ergo quae harum falsarum contraria est verae?
The first question, then, depends on this question as an effect upon its cause. For this reason, and by way of a conclusion to what he has just been saying, he adds the second question, which must be treated first so that once the cause is known the effect will be known: we must therefore consider to which false opinion the true opinion is contrary, whether it is to the false negation or to the false affirmation that it is to be judged contrary (23a32). And in order to propose the question by examples, he says, what I mean is this: there are three opinions of a good, such as of life. One is a true opinion, that it is good (for instance, that life is good). The other is a false negative, that it is not good (for instance, that life is not good). Still another, likewise false, is the affirmative of the contrary, that it is evil (for instance, that life is evil). The question is, then, which of these false opinions is contrary to the true one.
Peri.L13
355. Quod autem subdidit: et si est una, secundum quam contraria est, tripliciter legi potest.
Then he adds, the question, and if there is one, is either one the contrary (23a32). This passage can be read in three ways.
Peri.L13
Primo, dubitative, ut sit pars quaestionis; et tunc est sensus: quaeritur quae harum falsarum contraria est verae: et simul quaeritur, si est tantum una harum falsarum secundum quam fiat contraria ipsi verae: quia cum unum uni sit contrarium, ut dicitur in X metaphysicae, quaerendo quae harum sit contraria, quaeremus etiam an una earum sit contraria.
It can be read inquiringly so that it is a part of the question, and then the meaning is: which of these false opinions is contrary to the true opinion, and is there one of these by which the contrary to the true one is effected? For since one is contrary to one other, as is said in Metaphysics 10.1 (1055a19), in asking which of these is the contrary we are also asking whether one of them is the contrary.
Peri.L13
Alio modo, potest legi adversative, ut sit sensus: quaeritur quae harum sit contraria; quamquam sciamus quod non utraque sed una earum est secundum quam fit contrarietas.
This can also be read adversatively, and then the meaning is: which of these is the contrary, given that we know it is not both but one by which the contrariety is effected?
Peri.L13
Tertio modo, potest legi dividendo hanc particulam, et si est una, ab illa sequenti, secundum quam contraria est; et tunc prima pars expressive, secunda vero dubitative legitur; et est sensus: quaeritur quae harum falsarum contraria est verae, non solum si istae duae falsae inter se differunt in consequendo, sed etiam si utraque est una, idest alteri indivisibiliter unita, quaeritur secundum quam fit contrarietas.
This can be read in a third way by dividing the first clause, and if it is one, from the second clause, is either one the contrary. The first part is then read assertively, the second inquiringly, and the meaning is: which of these two false opinions is contrary to the true opinion if the two false opinions differ as to consequence, and also if both are one (that is, united to each other indivisibly)?
Peri.L13
Et hoc modo exponit Boethius, dicens quod Aristoteles apposuit haec verba propter contraria immediata, in quibus non differt contrarium a privativo. Inter contraria enim mediata et immediata haec est differentia, quod in immediatis a privativo contrarium non infertur. Non enim valet, corpus colorabile est non album, ergo est nigrum: potest enim esse rubrum. In immediatis autem valet; verbi gratia: animal est non sanum, ergo infirmum; numerus est non par, ergo impar. Voluit ergo Aristoteles exprimere quod nunc, cum quaerimus quae harum falsarum, scilicet negativae et affirmativae contrarii, sit contraria affirmativae verae, quaerimus universaliter sive illae duae falsae indivisibiliter se sequantur, sive non.
Boethius explains this passage in the last way. He says that Aristotle adds these words because of immediate contraries, in which the contrary does not differ from the privative, for the difference between mediate and immediate contraries is that in the former the contrary is not inferred from the privative. For example, this is not valid: “A colored body is not white, therefore it is black”—for it could be red. In immediate contraries, on the other hand, it is valid to infer the contrary from the privative; for instance, “An animal is not healthy, therefore it is ill; number is not even, therefore it is odd.” Therefore, Aristotle intends to show here that when we ask which of these false opinions (namely, negative and affirmative contraries) is contrary to the true affirmative, we are asking universally whether these two false opinions follow each other indivisibly or not.
Peri.L13
356. Deinde cum dicit: nam arbitrari, prosequitur hanc secundam quaestionem.
When he says, it is false, of course, to suppose (23b2), he proceeds with the second question.
Peri.L13
Et circa hoc quatuor facit.
About this he does four things.
Peri.L13
Primo, declarat quod contrarietas opinionum non attenditur penes contrarietatem materiae, circa quam versantur, sed potius penes oppositionem veri vel falsi;
First, he shows that contrariety of opinions is not determined by the contrariety of the matter involved, but rather by the opposition of true and false;
Peri.L13
secundo, declarat quod non penes quaecunque opposita secundum veritatem et falsitatem est contrarietas opinionum; ibi: si ergo boni etc.;
second, he shows that there is not contrariety of opinions in just any opposites according to truth and falsity, at: now if there is the opinion of that which is good, that it is good (23b7; [357]);
Peri.L13
tertio, determinat quod contrarietas opinionum attenditur penes per se primo opposita secundum veritatem et falsitatem tribus rationibus; ibi: sed in quibus primo fallacia etc.;
third, he determines that contrariety of opinions is concerned with the per se first opposites according to truth and falsity for three reasons, at: rather, those opinions in which there is fallacy (23b13; [358]);
Peri.L13
quarto declarat hanc determinationem inveniri in omnibus veram; ibi: manifestum est igitur et cetera.
fourth, he shows that this determination is true of all, at: it is evident that it will make no difference (24a3; [373]).
Peri.L13
Dicit ergo proponens intentam conclusionem, quod falsum est arbitrari opiniones definiri seu determinari debere contrarias ex eo quod contrariorum obiectorum sunt.
Aristotle says, then, proposing the conclusion he intends to prove, that it is false to suppose that opinions are to be defined or determined as contrary because they are about contrary objects.
Peri.L13
Et adducit ad hoc duplicem rationem.
He gives two arguments for this.
Peri.L13
Prima est: opiniones contrariae non sunt eadem opinio; sed contrariorum eadem est fortasse opinio; ergo opiniones non sunt contrariae ex hoc quod contrariorum sunt.
Contrary opinions are not the same opinion; but opinions about contraries are probably the same opinion; therefore, opinions are not contrary from the fact that they are about contraries.
Peri.L13
Secunda est: opiniones contrariae non sunt simul verae; sed opiniones contrariorum, sive plures, sive una, sunt simul verae quandoque; ergo opiniones non sunt contrariae ex hoc quod contrariorum sunt.
Also, contrary opinions are not simultaneously true; but opinions about contraries, whether many or one, are sometimes true simultaneously; therefore, opinions are not contraries because they are about contraries.
Peri.L13
Harum rationum, suppositis maioribus, ponit utriusque minoris declarationem simul,
Having supposed the majors of these arguments, he posits a manifestation of each minor at the same time.
Peri.L13
dicens: boni enim, quoniam bonum est, et mali, quoniam malum est, eadem fortasse opinio est, quoad primam.
In relation to the first argument, he says, for the opinion of that which is good, that it is good, and of that which is evil, that it is evil are probably the same (23b2).
Peri.L13
Et subdit esse vera, sive plures sive una sit, quoad secundam.
In relation to the second argument he adds: and, whether many or one, are true (23b2).
Peri.L13
Utitur autem dubitativo adverbio et disiunctione, quia non est determinandi locus an contrariorum eadem sit opinio, et quia aliquo modo est eadem et aliquo modo non. Si enim loquamur de habituali opinione, sic eadem est; si autem de actuali, sic non eadem est. Alia siquidem mentalis compositio actualiter fit, concipiendo bonum esse bonum, et alia concipiendo malum esse malum, licet eodem habitu utrunque cognoscamus, illud per se primo, et hoc secundario, ut dicitur IX metaphysicae.
He uses probably, an adverb expressing doubt and disjunction, because this is not the place to determine whether the opinion of contraries is the same opinion, and because in some way the opinion is the same and in some way not. In the case of habitual opinion, the opinion of contraries is the same, but in the case of an actual opinion it is not. One mental composition is actually made in conceiving that a good is good and another in conceiving that an evil is evil, although we know both by the same habit, the former per se and first, the latter secondarily, as is said in Metaphysics 9.4 (1051a4).
Peri.L13
Deinde subdit quod ista quae ad declarationem minorum sumpta sunt, scilicet bonum et malum, contraria sunt etiam contrarietate sumpta stricte in moralibus, ac per hoc congrua usi sumus declaratione.
Then he adds that good and evil—which are used for the manifestation of the minor—are contraries even when the contrariety is taken strictly in moral matters, and so in using this our exposition is apposite.
Peri.L13
Ultimo inducit conclusionem. Sed non in eo quod contrariorum opiniones sunt, contrariae sunt, sed magis in eo quod contrariae, idest, sed potius censendae sunt opiniones contrariae ex eo quod contrariae adverbialiter, scilicet contrario modo, idest vere et false enunciant. Et sic patet primum.
Finally, he draws the conclusion. Opinions are not contraries because they are about contraries, but rather because they are contraries (23b2), that is, opinions are to be considered as contrary from the fact that they enunciate contrarily and adverbially (namely, in a contrary mode)—that is, they enunciate truly and falsely. Thus the first argument is clear.
Peri.L13
357. Si ergo boni et cetera. Quia dixerat quod contrarietas opinionum accipitur secundum oppositionem veritatis et falsitatis earum, declarat modo quod non quaecunque secundum veritatem et falsitatem oppositae opiniones sunt contrariae, tali ratione. De bono, puta, de iustitia, quatuor possunt opiniones haberi, scilicet quod iustitia est bona, et quod non est bona, et quod est fugibilis, et quod est non appetibilis. Quarum prima est vera, reliquae sunt falsae. Inter quas haec est diversitas quod, prima negat idem praedicatum quod vera affirmabat; secunda affirmat aliquid aliud quod bono non inest; tertia negat id quod bono inest, non tamen illud quod vera affirmabat. Tunc sic. Si omnes opiniones secundum veritatem et falsitatem sunt contrariae, tunc uni, scilicet verae opinioni non solum multa sunt contraria, sed etiam infinita: quod est impossibile, quia unum uni est contrarium. Tenet consequentia, quia possunt infinitae imaginari opiniones falsae de una re similes ultimis falsis opinionibus adductis, affirmantes, scilicet ea quae non insunt illi, et negantes ea quae illi quocunque modo coniuncta sunt: utraque namque indeterminata esse et absque numero constat. Possumus enim opinari quod iustitia est quantitas, quod est relatio, quod est hoc et illud; et similiter opinari quod iustitia non sit qualitas, non sit appetibilis, non sit habitus.
When he says, now, if there is the opinion of that which is good, that it is good (23b7), he takes up the second point. Since he has just said that contrariety of opinions is taken according to their opposition of truth and falsity, he goes on to show that not just any opposites according to truth and falsity are contraries. This is his argument. Four opinions can be held about a good such as justice: that justice is good, that it is not good, that it is avoidable, that it is not desirable. Of these, the first is true, the rest false. The three false ones are diverse. The first denies the same predicate the true one affirmed; the second affirms something which does not belong to the good; the third denies what belongs to the good, but something other than the true one affirmed. Now if all opinions opposed as to truth and falsity are contraries, then not only are there many contraries to one true opinion, but an infinite number. But this is impossible, for one is contrary to one other. The consequence holds because infinite false opinions about one thing, similar to those cited, can be imagined; such opinions would affirm of it what does not belong to it and deny what is joined to it in some way. Both kinds are indeterminate and without number. We can think, for instance, that justice is a quantity, that it is a relation, that it is this and that; and likewise we can think that it is not a quality, is not desirable, is not a habit.
Peri.L13
Unde ex supradictis in propositione quaestionis, inferens pluralitatem falsarum contra unam veram, ait: si ergo est opinatio vera boni, puta iustitiae, quoniam est bonum; et si est etiam falsa opinatio negans idem, scilicet, quoniam non est quid bonum; est vero et tertia opinatio falsa quoque, affirmans aliquid aliud inesse illi, quod non inest nec inesse potest, puta, quod iustitia sit fugibilis, quod sit illicita; et hinc intelligitur quarta falsa quoque, quae scilicet negat aliquid aliud ab eo quod vera opinio affirmat inesse iustitiae, quod tamen inest, ut puta quod non sit qualitas, quod non sit virtus; si ita inquam est, nulla aliarum falsarum ponenda est contraria opinioni verae. Et exponens quid demonstret per ly aliarum, subdit: neque quaecunque opinio opinatur esse quod non est, ut tertii ordinis opiniones faciunt: neque quaecunque opinio opinatur non esse quod est, ut quarti ordinis opiniones significant. Et causam subdit: infinitae enim utraeque sunt, et quae esse opinantur quod non est, et quae non esse quod est, ut supra declaratum fuit. Non ergo quaecunque opiniones oppositae secundum veritatem et falsitatem contrariae sunt. Et sic patet secundum.
Hence, from what was said above in proposing the question, Aristotle infers a plurality of false opinions opposed to one true opinion: now if there is the opinion of that which is good, such as justice, that it is good; and there is a false opinion denying the same thing, namely, that it is not good; and besides these a third opinion, false also, affirming that some other thing belongs to justice that does not belong and cannot belong to it (for instance, that justice is avoidable or that it is illicit); and a fourth opinion, also false, that denies something other than the true opinion affirms, something, however, which does belong to justice (for instance, that it is not a quality, that it is not a virtue), then none of these other false enunciations are to be posited as the contrary of the true opinion. To explain what he is designating by of these others, he adds, neither those purporting that what is not, is, as opinions of the third order do, nor those purporting that what is, is not, as opinions of the fourth order signify. Then he adds the reason these cannot be posited as the contrary of the true opinion: for both the opinions that that is which is not, and that which is not, is, are infinite, as was shown above. Therefore, not just any opinions opposed according to truth and falsity are contraries. Thus the second argument is clear.
Peri.L13
L. 14 (1.14, 23b13–24b9)The Opposition of True and False that Constitutes Contrariety of Opinions Is Opposition According to Affirmation and Negation of the Same Predicate of the Same Subject
The Opposition of True and False that Constitutes Contrariety of Opinions Is Opposition According to Affirmation and Negation of the Same Predicate of the Same Subject
Peri.L14
Sed in quibuscumque fallacia est. Hae autem sunt ex his ex quibus sunt generationes: ex oppositis vero generationes sunt: quare etiam fallacia.
23b13. Rather, those opinions in which there is fallacy must be posited as contrary to true opinions. Now, the things from which fallacies arise are the things from which generations arise. But generations are from opposites; therefore, so are fallacies.
Peri.L14
Si ergo quod bonum est, et bonum, et non malum est; et hoc quidem secundum se, illud vero secundum accidens (accidit enim ei non malum esse); magis autem in unoquoque vera est, quae secundum se est etiam falsa, si quidem et vera. Ergo ea quae est, quoniam non est bonum quod bonum est, eius, quae secundum se falsa est; illa vero quae est, quoniam malum est, eius, quae est secundum accidens. Quare magis erit falsa de bono ea, quae est negationis opinio, quam ea, quae est contrarii. Falsus autem est maxime circa singula, qui habet contrariam opinionem: contraria enim sunt eorum, quae plurimum circa idem differunt. Si igitur harum contraria est altera, magis vero negationis est contraria; manifestum est quoniam haec erit contraria. Illa vero quae est, quoniam malum est, quod bonum est, implicita est. Etenim quoniam non bonum est, necesse est forte idem ipsum opinari.
23b15. Now, if that which is good is both good and not evil, the former per se, the latter accidentally (for it is accidental to that which is good not to be evil), and the true opinion which is a per se opinion of a thing is more true, then the false opinion which is a per se opinion is also more false. But the opinion that that which is good is not good is a false opinion about what belongs in itself to a good, and the opinion that it is evil is a false opinion concerning what belongs to it accidentally. Therefore, the opinion of the negation of the good will be more false than the opinion affirming a contrary. Now, the one who holds the contrary opinion about each thing is most mistaken; for contraries are those that differ most with respect to the same thing. If, then, of two opinions one is the contrary, but the opinion of the negation is more contrary, it is evident that it must be the contrary. The opinion that that which is good is evil, however, is implicative; for probably along with this opinion one must understand that the good is not good.
Peri.L14
Amplius si etiam in aliis similiter oportet se habere, et hoc modo videbitur bene esse dictum. Aut enim ubique ea, quae est contradictionis, aut nusquam. Quibus vero non est contrarium, de his quidem est falsa ea, quae est verae opposita; ut qui hominem non putat esse hominem, falsus est. Si ergo hae contrariae sunt, etiam aliae quae sunt contradictiones.
23b27. Further, if this necessarily holds in a similar way in all other cases, it would seem that what we have said is correct; for the opposition of contradiction either holds everywhere or nowhere. Now, in the case where there is no contrary, that opinion is false which is the opposite of the true opinion; for instance, he who thinks man is not man thinks falsely. If, then, these are contraries, the others in which there is contradiction are also contraries.
Peri.L14
Amplius similiter se habet opinio boni, quoniam bonum est, et non boni, quoniam non bonum est. Et praeter has boni, quoniam non bonum est, et non boni quoniam bonum est. Illi ergo quae est, non boni quoniam non bonum est; verae opinationi quaenam est contraria? non enim ea, quae dicit quoniam malum est: simul enim aliquando verae erunt. Nunquam autem vera verae est contraria: est enim quidquam non bonum malum. Quare contingit simul esse veras. At vero nec illa, quae est, quod non malum: vera enim et haec: simul enim et haec erunt. Relinquitur ergo, ei, quae est non bonum, quoniam non bonum est, contraria ea, quae est, non boni, quoniam bonum est. Falsa enim haec. Quare et ea, quae est boni, quoniam non bonum est, ei, quae est boni, quoniam est bonum.
23b33. Again, the opinions of that which is good, that it is good, and of that which is not good, that it is not good, are parallel; so also are the opinions of that which is good, that it is not good, and of that which is not good, that it is good. What, then, would be the contrary of a true opinion that that which is not good is not good? It is not the opinion saying that it is evil. This might be at the same time true, and a true opinion is never contrary to a true opinion; for some things that are not good are evil, and therefore it is possible for both opinions to be true. Nor is the opinion that it is not evil the contrary, for this too might be true, since something could be at one and the same time not good and not evil. It remains, therefore, that the contrary of an opinion that that which is not good is not good, is the false opinion that that which is not good is good; for the former is true. Therefore, also the opinion that that which is good is not good is contrary to the opinion that that which is good is good.
Peri.L14
Manifestum est autem quoniam nihil interest nec si universaliter ponamus affirmationem. Universalis enim negatio contraria erit; ut opinioni, quae opinatur, quoniam omne quod est bonum, bonum est, ea quae est, quoniam nihil horum quae bona sunt, bonum est. Nam ea quae est boni quoniam bonum est, si universaliter sit bonum, eadem est ei quae opinatur, quod quidquid bonum est, quoniam bonum est. Hoc autem nihil differt ab eo quod est, quod omne quod est bonum, bonum est. Similiter autem et in non bono.
24a3. It is evident that it will make no difference if we posit the affirmation universally, for the universal negation will be the contrary. For instance, the contrary of the opinion that everything that is good is good, is that nothing that is good is good. For the opinion that that which is good is good, if the good is taken universally, is the same as the opinion that whatever is good is good; and this is no different from the opinion that everything that is good is good. And the same is the case with respect to the not good.
Peri.L14
Quare si in opinione sic se habet; sunt autem hae quae sunt in voce affirmationes et negationes notae eorum quae sunt in anima; manifestum est quoniam affirmationi contraria quidem negatio est, quae de eodem universaliter; ut ei, quae est, quoniam omne bonum bonum est, vel quoniam omnis homo bonus, ea quae est, quoniam nullum vel nullus: contradictorie autem quae est, quod non omne aut non omnis.
24b1. If, therefore, this is the case with respect to opinion, and affirmations and negations in vocal sound are signs of those in the soul, it is evident that the contrary of the affirmation is the negation of the same subject universally. For example, the contrary of the enunciation “everything good is good” is “nothing good is good,” or of “every man is good” is “no man is good.” The contradictories, on the other hand, are “not everything good is good,” and “not every man is good.”
Peri.L14
Manifestum est autem, quoniam et veram verae non contingit esse contrariam, nec opinionem nec contradictionem. Contrariae enim, quae circa opposita sunt; circa eadem autem contingit verum dicere eumdem; simul autem non contingit eidem inesse contraria.
24b6. It is evident, too, that true cannot be contrary to true, either in opinion or in contradiction. For contraries are about opposites, and while it is possible for the same thing to be said truly about contraries, it is not possible for contraries to belong at once to the same subject.
Peri.L14
358. Quia subtili indagatione ostendit quod nec materiae contrarietas, nec veri falsique qualiscunque oppositio contrarietatem opinionum constituit, sed quod aliqua veri falsique oppositio id facit, ideo nunc determinare intendit qualis sit illa veri falsique oppositio, quae opinionum contrarietatem constituit. Ex hoc enim directe quaestioni satisfit. Et intendit quod sola oppositio opinionum secundum affirmationem et negationem eiusdem de eodem etc. constituit contrarietatem earum. Unde intendit probare istam conclusionem per quam ad quaesitum respondet: opiniones oppositae secundum affirmationem et negationem eiusdem de eodem sunt contrariae; et consequenter illae, quae sunt oppositae secundum affirmationem contrariorum praedicatorum de eodem, non sunt contrariae, quia sic affirmativa vera haberet duas contrarias, quod est impossibile. Unum enim uni est contrarium.
Aristotle has just completed a subtle investigation in which he has shown that contrariety of matter does not constitute contrariety of opinion, nor does just any kind of opposition of true and false, but some opposition of true and false does. Now he intends to determine what kind of opposition of true and false it is that constitutes contrariety of opinions, for this will answer the question directly. He maintains that only opposition of opinions according to affirmation and negation of the same thing of the same thing (and so on) constitutes their contrariety. Accordingly, as the response to the question, he intends to prove the following conclusion: opinions opposed according to affirmation and negation of the same thing of the same thing are contraries; and consequently, opinions opposed according to affirmation of contrary predicates of the same subject are not contraries, for if these were contraries, the true affirmative would have two contraries, which is impossible, since one is contrary to one other.
Peri.L14
359. Probat autem istam conclusionem tribus rationibus.
Aristotle uses three arguments to prove this conclusion.
Peri.L14
Prima est: opiniones in quibus primo est fallacia sunt contrariae; opiniones oppositae secundum affirmationem et negationem eiusdem de eodem sunt in quibus primo est fallacia; ergo opiniones oppositae secundum affirmationem et negationem eiusdem de eodem sunt contrariae.
The first one is as follows. Those opinions in which there is fallacy first are contraries. Opinions opposed according to affirmation and negation of the same predicate of the same subject are those in which there is fallacy first. Therefore, these are contraries.
Peri.L14
Sensus maioris est: opiniones quae primo ordine naturae sunt termini fallaciae, idest deceptionis seu erroris, sunt contrariae: sunt enim, cum quis fallitur seu errat, duo termini, scilicet a quo declinat, et ad quem labitur. Huius rationis in littera primo ponitur maior, cum dicitur: sed in quibus primo fallacia est; adversative enim continuans sermonem supradictis, insinuavit non tot enumeratas opiniones esse contrarias, sed eas in quibus primo fallacia est modo exposito.
The sense of the major is this: opinions which first in the order of nature are the limits of fallacy (that is, of deception or error) are contraries; for when someone is deceived or errs, there are two limits, the one from which he turns away and the one toward which he turns. In the text the major of the argument is posited first: rather, those opinions in which there is fallacy must be posited as contrary to true opinions (23b13). By uniting this part of the text adversatively with what was said previously, Aristotle implies that not just any of the number of opinions enumerated are contraries, but those in which there is fallacy first in the manner we have explained.
Peri.L14
Deinde subdit probationem minoris talem: eadem proportionaliter sunt, ex quibus sunt generationes et ex quibus sunt fallaciae; sed generationes sunt ex oppositis secundum affirmationem et negationem; ergo et fallaciae sunt ex oppositis secundum affirmationem et negationem. Quod erat assumptum in minore. Unde ponens maiorem huius prosyllogismi, ait: haec autem, scilicet fallacia, est ex his, scilicet terminis, proportionaliter tamen, ex quibus sunt et generationes. Et subsumit minorem: ex oppositis vero, scilicet secundum affirmationem et negationem, et generationes fiunt. Et demum concludit: quare etiam fallacia, scilicet, est ex oppositis secundum affirmationem et negationem eiusdem de eodem.
Then he gives this proof of the minor: those things from which generations are and from which fallacies are, are the same proportionally; generations are from opposites according to affirmation and negation; therefore, fallacies, too, are from opposites according to affirmation and negation (which was assumed in the minor). Hence he posits the major of this prosyllogism: now the things from which fallacies arise, namely, limits, are the things from which generations arise (23b13)—although proportionally. Under it he posits the minor: but generations are from opposites, that is, according to affirmation and negation. Finally, he concludes, therefore, also fallacies, that is, they are from opposites according to affirmation and negation of the same thing of the same thing.
Peri.L14
360. Ad evidentiam huius probationis scito quod idem faciunt in processu intellectus cognitio et fallacia seu error, quod in processu naturae generatio et corruptio. Sicut namque perfectiones naturales generationibus acquiruntur, corruptionibus desinunt; ita cognitione perfectiones intellectuales acquiruntur, erroribus autem seu deceptionibus amittuntur. Et ideo, sicut tam generatio quam corruptio est inter affirmationem et negationem, ut proprios terminos, ut dicit V Physic.; ita tam cognoscere aliquid, quam falli circa illud, est inter affirmationem et negationem, ut proprios terminos: ita quod id ad quod primo attingit cognoscens aliquid in secunda operatione intellectus est veritatis affirmatio, et quod per se primo abiicitur est illius negatio. Et similiter quod per se primo perdit qui fallitur est veritatis affirmatio, et quod primo incurrit est veritatis negatio. Recte ergo dixit quod iidem sunt termini inter quos primo est generatio, et illi inter quos est primo fallacia, quia utrobique termini sunt affirmatio et negatio.
This proof will be more evident from the following. Knowledge and fallacy, or error, bring about the same thing in the intellect’s progression as generation and corruption do in nature’s progression. For just as natural perfections are acquired by generations and perish by corruptions, so intellectual perfections are acquired by knowledge and lost by errors or deceptions. Accordingly, just as generation and corruption are between affirmation and negation as proper terms, as is said in Physics 5.1 (224b35), so both to know something and to be deceived about it is between affirmation and negation as proper terms. Consequently, what one who knows attains first in the second operation of the intellect is affirmation of the truth, and what he rejects per se and first is the negation of it. In like manner, what he who is deceived loses per se and first is affirmation of the truth, and acquires first is negation of the truth. Therefore, Aristotle is correct in maintaining that the terms between which there is generation first and between which there is fallacy first are the same, because with respect to both, the terms are affirmation and negation.
Peri.L14
361. Deinde cum dicit: si ergo quod bonum est etc., intendit probare maiorem principalis rationis. Et quia iam declaravit quod ea, in quibus primo est fallacia, sunt affirmatio et negatio, ideo utitur, loco maioris probandae, scilicet, opiniones in quibus primo est fallacia, sunt contrariae, sua conclusione, scilicet, opiniones oppositae secundum affirmationem et negationem eiusdem sunt contrariae. Aequivalere enim iam declaratum est. Fecit autem hoc consuetae brevitati studens, quoniam sic procedendo, et probat maiorem, et respondet directe quaestioni, et applicat ad propositum simul. Probat ergo loco maioris conclusionem principaliter intentam quaestionis, hanc, scilicet: opiniones oppositae secundum affirmationem et negationem eiusdem sunt contrariae; et non illae, quae sunt oppositae secundum contrariorum affirmationem de eodem.
When he says, now, if that which is good is both good and not evil (23b15), he intends to prove the major of the principal argument. He has already shown that the opinions in which there is fallacy first are affirmation and negation, and therefore in place of the major to be proved (that is, opinions in which it there is fallacy first are contraries) he uses his conclusion—which has already been shown to be equivalent—that opinions opposed according to affirmation and negation of the same thing are contraries. Thus with his customary brevity he at once proves the major, responds directly to the question, and applies it to what he has proposed. In place of the major, then, he proves the conclusion principally intended, namely, that opinions opposed according to affirmation and negation of the same thing are contraries, and not those opposed according to affirmation of contraries about the same thing.
Peri.L14
Et intendit talem rationem. Opinio vera et eius magis falsa sunt contrariae opiniones; oppositae secundum affirmationem et negationem sunt vera et eius magis falsa; ergo opiniones oppositae secundum affirmationem et negationem sunt contrariae.
His argument is as follows. A true opinion and the opinion that is more false in respect to it are contrary opinions, but opinions opposed according to affirmation and negation are the true opinion and the opinion that is more false in respect to it; therefore, opinions opposed according to affirmation and negation are contraries.
Peri.L14
Maior probatur ex eo quod, quae plurimum distant circa idem sunt contraria; vera autem et eius magis falsa plurimum distant circa idem, ut patet.
The major is proved thus. Those things that are most distant in respect to the same thing are contraries; but the true and the more false are most distant in respect to the same thing, as is clear.
Peri.L14
Minor vero probatur ex eo quod opposita secundum negationem eiusdem de eodem est per se falsa respectu suae affirmationis verae. Opinio autem per se falsa magis falsa est quacunque alia. Unumquodque enim quod est per se tale, magis tale est quolibet quod est per aliud tale.
The proof of the minor is that the opposite according to negation of the same thing of the same thing is per se false in relation to the true affirmation of it. But a per se false opinion is more false than any other, since each thing that is per se such is more such than anything that is such by reason of something else.
Peri.L14
362. Unde ad suprapositas opiniones in propositione quaestionis rediens, ut ex illis exemplariter clarius intentum ostendat, a probatione minoris inchoat tali modo. Sint quatuor opiniones, duae verae, scilicet, bonum est bonum, bonum non est malum, et duae falsae, scilicet, bonum non est bonum, et, bonum est malum. Clarum est autem quod prima vera est ratione sui, secunda autem est vera secundum accidens, idest, ratione alterius, quia scilicet non esse malum est coniunctum ipsi bono: ideo enim ista est vera, bonum non est malum, quia bonum est bonum, et non e contra; ergo prima quae est secundum se vera, est magis vera quam secunda: quia in unoquoque genere quae secundum se est vera est magis vera. Illae autem duae falsae eodem modo censendae sunt, quod scilicet magis falsa est, quae secundum se est falsa. Unde quia prima earum, scilicet, bonum non est bonum, quae est negativa, est per se et non ratione alterius falsa, relata ad illam affirmativam, bonum est bonum; et secunda, scilicet, bonum est malum, quae est affirmativa contrarii, ad eamdem relata est falsa per accidens, idest ratione alterius (ista enim, scilicet, bonum est malum, non immediate falsificatur ab illa vera, scilicet bonum est bonum, sed mediante illa alia falsa, scilicet, bonum non est bonum); idcirco magis falsa respectu affirmationis verae est negatio eiusdem quam affirmatio contrarii. Quod erat assumptum in minore.
Accordingly, returning to the opinions already given in proposing the question so as to show his intention more clearly by example, he begins with the proof of the minor. There are four opinions, of which two are true, “a good is good” and “a good is not evil”; and two are false, “a good is not good” and “a good is evil.” It is evident that the first is true by reason of itself and the second accidentally, that is, by reason of another, for not to be evil is added to that which is good. Hence, “a good is not evil” is true because a good is good, and not contrarily. Therefore, the first of these opinions, which is per se true, is more true than the second, for in each genus that which per se is true is more true. The two false opinions are to be judged in the same way. The more false is the one that is per se false. The first of them, the negative, “a good is not good,” in relation to the affirmative, “a good is good,” is per se false, not false by reason of another. The second, the affirmative of the contrary, “a good is evil,” in relation to the same opinion, is false accidentally, that is, by reason of another (for “a good is evil” is not immediately falsified by the true opinion, “a good is good,” but mediately through the other false opinion “a good is not good”). Therefore, the negation of the same thing is more false in respect to a true affirmation than the affirmation of a contrary. This was assumed in the minor.
Peri.L14
363. Unde rediens ad supra positas (ut dictum est) opiniones, infert primas duas veras opiniones dicens: si ergo quod bonum est et bonum est et non est malum, et hoc quidem, scilicet quod dicit prima opinio, est verum secundum se, idest ratione sui; illud vero, scilicet quod dicit secunda opinio, est verum secundum accidens, quia accidit, idest, coniunctum est ei, scilicet bono, malum non esse. In unoquoque autem ordine magis vera est illa quae secundum se est vera. Etiam igitur falsa magis est quae secundum se falsa est: siquidem et vera huius est naturae, ut declaratum est, quod scilicet magis vera est, quae secundum se est vera. Ergo illarum duarum opinionum falsarum in quaestione propositarum, scilicet, bonum non est bonum, et, bonum est malum, ea quae est dicens, quoniam non est bonum quod bonum est, idest negativa; scilicet, bonum non est bonum, est consistens falsa secundum se, idest, ratione sui continet in seipsa falsitatem; illa vero reliqua falsa opinio, quae est dicens, quoniam malum est, idest, affirmativa contraria, scilicet, bonum est malum, eius, quae est, idest, illius affirmationis dicentis, bonum est bonum, secundum accidens, idest, ratione alterius falsa est.
As was pointed out above, Aristotle returns to the opinions already posited, and infers the first two true opinions: now, if that which is good is both good and not evil (23b15), and if what the first opinion says is true per se, that is, by reason of itself; and what the second opinion says is true accidentally (since it is accidental or added to the good not to be evil); and if in each order that which is per se true is more true, then that which is per se false is more false, since, as has been shown, the true also is of this nature—namely, that the more true is that which per se is true. Therefore, of the two false opinions proposed in the question, namely, “a good is not good,” and “a good is evil,” the one saying that what is good is not good, namely, the negative, is an opinion positing what is per se false—that is, by reason of itself it contains falsity in it. The other false opinion, the one saying it is evil—namely, the affirmative contrary in respect to the affirmation saying that a good is good—is false accidentally, that is, by reason of another.
Peri.L14
Deinde subdit ipsam minorem: quare erit magis falsa de bono, opinio negationis, quam contrarii.
Then he gives the minor: therefore, the opinion of the negation of the good will be more false than the opinion affirming a contrary (23b15).
Peri.L14
Deinde ponit maiorem dicens quod, semper magis falsus circa singula est ille qui habet contrariam opinionem, ac si dixisset, verae opinioni magis falsa est contraria. Quod assumptum erat in maiore. Et eius probationem subdit, quia contrarium est de numero eorum quae circa idem plurimum differunt. Nihil enim plus differt a vera opinione quam magis falsa circa illam.
Next, he posits the major, the one who holds the contrary judgment about each thing is most mistaken (23b15), that is, in relation to the true judgment the contrary is more false. This was assumed in the major. He gives as the proof of this: for contraries are those that differ most with respect to the same thing, for nothing differs more from a true opinion than the more false opinion in respect to it.
Peri.L14
364. Ultimo directe applicat ad quaestionem dicens: quod si (pro, quia) harum falsarum, scilicet, negationis eiusdem et affirmationis contrarii, altera est contraria verae affirmationi, opinio vero contradictionis, idest, negationis eiusdem de eodem, magis est contraria secundum falsitatem, idest, magis est falsa, manifestum est quoniam haec, scilicet opinio falsa negationis, erit contraria affirmationi verae, et e contra. Illa vero opinio quae est dicens, quoniam malum est quod bonum est, idest, affirmatio contrarii, non contraria sed implicita est, idest, sed implicans in se verae contrariam, scilicet, bonum non est bonum. Etenim necesse est ipsum opinantem affirmationem contrarii opinari, quoniam idem de quo affirmat contrarium non est bonum. Oportet siquidem si quis opinatur quod vita est mala, quod opinetur quod vita non sit bona. Hoc enim necessario sequitur ad illud, et non e converso; et ideo affirmatio contrarii implicita dicitur. Negatio autem eiusdem de eodem implicita non est. Et sic finitur prima ratio.
Finally, he directly approaches the question. If (for “since”), then, of two opinions (namely, false opinions—the negation of the same thing and the affirmation of a contrary), one is the contrary of the true affirmation, and the contradictory opinion (that is, the negation of the same thing of the same thing), is more contrary according to falsity (namely, is more false), it is evident that the false opinion of negation will be contrary to the true affirmation, and conversely. The opinion saying that what is good is evil (that is, the affirmation of a contrary) is not the contrary but implies it, that is, it implies in itself the opinion contrary to the true opinion (namely, “a good is not good”). The reason for this is that the one conceiving the affirmation of a contrary must conceive that the same thing of which he affirms the contrary is not good. If, for example, someone conceives that life is evil, he must conceive that life is not good, for the former necessarily follows upon the latter and not conversely. Hence, affirmation of a contrary is said to be implicative, but negation of the same thing of the same thing is not implicative. This concludes the first argument.
Peri.L14
365. Notandum est hic primo quod ista regula generalis tradita hic ab Aristotele de contrarietate opinionum, quod scilicet contrariae opiniones sunt quae opponuntur secundum affirmationem et negationem eiusdem de eodem, et in se et in assumptis ad eius probationem propositionibus scrupulosa est. Unde multa hic insurgunt dubia.
The general rule about the contrariety of opinions that Aristotle has given here (namely, that contrary opinions are those opposed according to affirmation and negation of the same thing of the same thing) is accurate both in itself and in the propositions assumed for its proof. Many questions may arise, however, as a consequence of this doctrine and its proof.
Peri.L14
Primum est quia cum oppositio secundum affirmationem et negationem non constituat contrarietatem sed contradictionem apud omnes philosophos, quomodo Aristoteles opiniones oppositas secundum affirmationem et negationem ex hoc contrarias ponat. Augetur et dubitatio quia dixit quod ea in quibus primo est fallacia sunt contraria, et tamen subdit quod sunt oppositae sicut termini generationis, quos constat contradictorie opponi. Nec dubitatione caret quomodo sit verum id quod supra diximus ex intentione s. Thomae, quod nullae duae opiniones opponantur contradictorie, cum hic expresse dicitur aliquas opponi secundum affirmationem et negationem.
First of all, all philosophers hold that opposition according to affirmation and negation constitutes contradiction, not contrariety. How, then, can Aristotle maintain that opinions opposed in this way are contraries? The difficulty is augmented by the fact that he has said that those opinions in which there is fallacy first are contraries, yet he adds that they are opposed as the terms of generation are, which he establishes to be opposed contradictorily. In addition, there is a difficulty as to the way in which the assertion of St. Thomas, which we used above, is true, namely, that no two opinions are opposed contradictorily, since here it is explicitly said that some are opposed according to affirmation and negation.
Peri.L14
Dubium secundo insurgit circa id quod assumpsit, quod contraria cuiusque verae est per se falsa. Hoc enim non videtur verum. Nam contraria istius verae, Socrates est albus, est ista, Socrates non est albus, secundum determinata; et tamen non est per se falsa. Sicut namque sua opposita affirmatio est per accidens vera, ita ista est per accidens falsa. Accidit enim isti enunciationi falsitas. Potest enim mutari in veram, quia est in materia contingenti.
The second question involves his assumption that the contrary of each true opinion is per se false. This does not seem to be true, for according to what was determined previously, the contrary of the true opinion “Socrates is white” is “Socrates is not white.” But this is not per se false, for the opposed affirmation is true accidentally, and hence its negation is false accidentally. Falsity is accidental to such an enunciation because, being in contingent matter, it can be changed into a true one.
Peri.L14
Dubium est tertio circa id quod dixit: magis vero contradictionis est contraria. Ex hoc enim videtur velle quod utraque, scilicet, opinio negationis et contrarii, sit contraria verae affirmationi; et consequenter vel uni duo ponit contraria, vel non loquitur de contrarietate proprie sumpta: cuius oppositum supra ostendimus.
A third difficulty arises from the fact that Aristotle says the contradictory opinion is not contrary (23b15). He seems to be proposing, according to this, that both the opinion of the negation and of a contrary are contrary to a true affirmation. Consequently, he is either positing two opinions contrary to one or he is not taking contrariety strictly, although we showed above that he was taking contrariety properly and strictly.
Peri.L14
366. Ad evidentiam omnium, quae primo loco adducuntur, sciendum quod opiniones seu conceptiones intellectuales, in secunda operatione de quibus loquimur, possunt tripliciter accipi:
In order to answer all of the difficulties in regard to the first argument, it must be noted that opinions, or intellectual conceptions in the second operation, can be taken in three ways:

uno modo, secundum id quod sunt absolute;
in one way, according to what they are absolutely;
Peri.L14
alio modo, secundum ea quae repraesentant absolute;
in a second, according to the things they represent absolutely;
Peri.L14
tertio, secundum ea quae repraesentant, ut sunt in ipsis opinionibus.
in a third, according to the things they represent, as they are in opinions.
Peri.L14
Primo membro omisso, quia non est praesentis speculationis,
We will omit the first since it does not belong to the present consideration.
Peri.L14
scito quod si accipiantur secundo modo secundum repraesentata, sic invenitur inter eas et contradictionis, et privationis, et contrarietatis oppositio. Ista siquidem mentalis enunciatio, Socrates est videns, secundum id quod repraesentat opponitur illi, Socrates non est videns, contradictorie; privative autem illi, Socrates est caecus; contrarie autem illi, Socrates est luscus; si accipiantur secundum repraesentata. Ut enim dicitur in postpraedicamentis, non solum caecitas est privatio visus, sed etiam caecum esse est privatio huius quod est esse videntem, et sic de aliis.
If they are taken in the second way, that is, according to the things represented, there can be opposition of contradiction, of privation, and of contrariety among them. The mental enunciation “Socrates sees,” according to what it represents, is opposed contradictorily to “Socrates does not see”; privatively to “Socrates is blind”; and contrarily to “Socrates is purblind.” Aristotle points out the reason for this in Categories 10 (12a35): not only is blindness privation of sight but to be blind is also a privation of to be seeing, and so of others.
Peri.L14
Si vero accipiantur opiniones tertio modo, scilicet, prout repraesentata per eas sunt in ipsis, sic nulla oppositio inter eas invenitur nisi contrarietas: quoniam sive opposita contradictorie sive privative sive contrarie repraesententur, ut sunt in opinionibus, illius tantum oppositionis capaces sunt, quae inter duo entia realia inveniri potest. Opiniones namque realia entia sunt. Regulare enim est quod quidquid convenit alicui secundum esse quod habet in alio, secundum modum et naturam illius in quo est sibi convenit, et non secundum quod exigeret natura propria. Inter entia autem realia contrarietas sola formaliter reperitur. Taceo nunc de oppositione relativa. Opiniones ergo hoc modo sumptae, si oppositae sunt, contrarietatem sapiunt, sed non omnes proprie contrariae sunt, sed illae quae plurimum differunt circa idem veritate et falsitate. Has autem probavit Aristoteles esse opiniones affirmationis et negationis eiusdem de eodem. Istae igitur verae contrariae sunt. Reliquae vero per reductionem ad has contrariae dicuntur.
Opinions taken in the third way, that is, as the things represented through opinions are in the opinions, have no opposition except contrariety; for opposites as they are in opinions, whether represented contradictorily or privatively or contrarily, only admit of the opposition that can be found between two real beings, for opinions are real beings. The rule is that whatever belongs to something according to the being which it has in another belongs to it according to the mode and nature of that in which it is, and not according to what its own nature would require. Now, between real beings only contrariety is found formally. (I am omitting here the consideration of relative opposition.) Therefore, opinions taken in this mode, if they are opposed, represent contrariety, although not all are contraries properly. Only those differing most in respect to truth and falsity about the same thing are contraries properly. Now Aristotle proved that these are judgments affirming and denying the same thing of the same thing. Therefore, these are the true contraries. The rest are called contraries by reduction to these.
Peri.L14
367. Ex his patet quid ad obiecta dicendum sit. Fatemur enim quod affirmatio et negatio in seipsis contradictionem constituunt; in opinionibus vero existentes contrarietatem inter illas causant propter extremam distantiam, quam ponunt inter entia realia, opinionem scilicet veram et opinionem falsam circa idem. Stantque ista duo simul quod ea, in quibus primo est fallacia, sint opposita ut termini generationis, et tamen sint contraria utendo supradicta distinctione: sunt enim opposita contradictorie ut termini generationis secundum repraesentata; sunt autem contraria, secundum quod habent in seipsis illa contradictoria. Unde plurimum differunt. Liquet quoque ex hoc quod nulla est dissentio inter dicta Aristotelis et s. Thomae, quia opiniones aliquas opponi secundum affirmationem et negationem verum esse confitemur, si ad repraesentata nos convertimus, ut hic dicitur.
From this the answer to the objections is clear. We grant that affirmation and negation in themselves constitute contradiction. In actual judgments, affirmation and negation cause contrariety between opinions because of the extreme distance they posit between real beings, namely, true opinion and false opinion about the same thing. And these two stand at the same time: those in which there is fallacy first are opposed as the terms of generation are, and yet they are contraries by the use of the foresaid distinction—for they are opposed contradictorily as terms of generation according to the things represented, but they are contraries insofar as they have in themselves those contradictories and hence differ most. It is also evident that there is no disagreement between Aristotle and St. Thomas, for we have shown that it is true that some opinions are opposed according to affirmation and negation if we consider the things represented, as is said here.
Peri.L14
368. Tu autem qui perspicacioris ac provectioris ingenii es compos, hinc habeto quod inter ipsas opiniones oppositas quidam tantum motus est, eo quod de affirmato in affirmatum mutatio fit: inter ipsas vero secundum repraesentata, similitudo quaedam generationis et corruptionis invenitur, dum inter affirmationem et negationem mutatio clauditur.
It will be noted, however, by those of you who are more penetrating and advanced in your thinking, that between opposite opinions there is something of true motion when a change is made from the affirmed to the affirmed; but according to the order of representation there is a certain similitude to generation and corruption so long as the change is bounded by affirmation and negation. Consequently, fallacy or error may be regarded in different ways.
Peri.L14
Unde et fallacia sive error quandoque et motus et mutationis rationem habet diversa respiciendo, quando scilicet ex vera in per se falsam, vel e converso, quis mutat opinionem;
Sometimes it has the aspect of both movement and change. This is the case when someone changes his opinion from a true one to one that is per se false, or conversely.
Peri.L14
quandoque autem solam mutationem imitatur, quando scilicet absque praeopinata veritate ipsam falsam offendit quis opinionem;
Sometimes change alone is imitated. This happens when someone arrives at a false opinion apart from a former true opinion.
Peri.L14
quandoque vero motus undique rationem possidet, quando scilicet ex vera affirmatione in falsam circa idem contrarii affirmationem transit.
Sometimes, however, there is movement in every respect. This is the case when reason passes from the true affirmation to the false affirmation of a contrary about the same thing.
Peri.L14
Quia tamen prima ut quis fallatur radix est oppositio affirmationis et negationis, merito ea in quibus primo est fallacia, sicut generationis terminos opponi dixit.
However, since the first root of being in error is the opposition of affirmation and negation, Aristotle is correct in saying that those in which there is fallacy first are opposed as are the terms of generation.
Peri.L14
369. Ad dubium secundo loco adductum dico quod peccatur ibi secundum aequivocationem illius termini per se falsa, seu per se vera. Opinio enim et similiter enunciatio potest dici dupliciter per se vera seu falsa.
With respect to the second question, I say that there is an equivocation of the term “per se false” and “per se true” in the objection. Opinion, as well as enunciation, can be called per se true or false in two ways.
Peri.L14
Uno modo, in seipsa, sicut sunt omnes verae secundum illos modos perseitatis qui enumerantur I posteriorum, et similiter falsae secundum illosmet modos, ut, homo non est animal. Et hoc modo non accipitur in hac regula de contrarietate opinionum et enunciationum opinio per se vera aut falsa, ut efficaciter obiectio adducta concludit. Si enim ad contrarietatem opinionum hoc exigeretur non possent esse opiniones contrariae in materia contingenti: quod est falsissimum.
In one way, it can be called per se true in itself. This is the case in respect to all opinions and enunciations that are in accordance with the modes of essentiality enumerated in Posterior Analytics 1.4 (73a34–73b15). Similarly, they can be said to be per se false according to the same modes. An example of this would be “man is not an animal.” Per se true or false is not taken in this mode in the rule about contrariety of opinions and enunciations, as the objection concludes. For if this were needed for contrariety of opinions, there could not be contrary opinions in contingent matter, which is false.
Peri.L14
Alio modo potest dici opinio sive enunciatio per se vera aut falsa respectu suae oppositae. Per se vera quidem respectu suae falsae, et per se falsa respectu suae verae. Et tunc nihil aliud est dicere, est per se vera respectu illius, nisi quod ratione sui et non alterius verificatur ex falsitate illius. Et similiter cum dicitur, est per se falsa respectu illius, intenditur quod ratione sui et non alterius falsificatur ex illius veritate. Verbi gratia; istius verae, Socrates currit, non est per se falsa, Socrates sedet, quia falsitas eius non immediate sequitur ex illa, sed mediante ista alia falsa, Socrates non currit, quae est per se illius falsa, quia ratione sui et non per aliquod medium ex illius veritate falsificatur, ut patet. Et similiter istius falsae, Socrates est quadrupes, non est per se vera ista, Socrates est bipes, quia non per seipsam veritas istius illam falsificat, sed mediante ista, Socrates non est quadrupes, quae est per se vera respectu illius: propter seipsam enim falsitate istius verificatur, ut de se patet. Et hoc secundo modo utimur istis terminis tradentes regulam de contrarietate opinionum et enunciationum. Invenitur siquidem sic universaliter vera in omni materia regula dicens quod, vera et eius per se falsa, et falsa et eius per se vera, sunt contrariae.
Second, an opinion or enunciation can be said to be per se true or false in respect to its opposite: per se true with respect to its opposite false opinion, and per se false with respect to its opposite true opinion. Accordingly, to say that an opinion is per se true with regard to its opposite is to say that on its own account and not on account of another it is verified by the falsity of its opposite. Similarly, to say that an opinion is per se false with regard to its opposite means that on its own account and not on account of another it is falsified by the truth of the opposite. For example, the opinion that is per se false in respect to the true opinion “Socrates is running” is not “Socrates is sitting,” since the falsity of the latter does not immediately follow from the former, but mediately from the false opinion, “Socrates is not running.” It is the latter opinion that is per se false in relation to “Socrates is running,” since it is falsified on its own account by the truth of the opinion “Socrates is running,” and not through an intermediary. Similarly, the per se true opinion in respect to the false opinion “Socrates is four-footed” is not “Socrates is two-footed,” for the truth of the latter does not by itself make the former false; rather, it is through “Socrates is not four-footed” as a medium, which is per se true in respect to “Socrates is four-footed”; for “Socrates is not four-footed” is verified on its own account by the falsity of “Socrates is four-footed,” as is evident. We are using “per se true” and “per se false” in this second mode in propounding the rule concerning contrariety of opinions and enunciations. Thus it is universally true in all matter that the true opinion and the per se false opinion in relation to it, and the false opinion and the per se true in relation to it are contraries.
Peri.L14
Unde patet responsio ad obiectionem, quia procedit accipiendo ly per se vera, et per se falsa primo modo.
Consequently, the response to the objection is clear, for it results from taking “per se true” and “per se false” in the first mode.
Peri.L14
370. Ad ultimum dubium dicitur quod, quia inter opiniones ad se invicem pertinentes nulla alia est oppositio nisi contrarietas, coactus fuit Aristoteles (volens terminis specialibus uti) dicere quod una est magis contraria quam altera, insinuans quidem quod utraque contrarietatis oppositionem habet respectu illius verae. Determinat tamen immediate quod tantum una earum, scilicet negationis opinio, contraria est affirmationi verae. Subdit enim: manifestum est quoniam haec contraria erit. Duo ergo dixit, et quod utraque, tam scilicet negatio eiusdem quam affirmatio contrarii, contrariatur affirmationi verae, et quod una tantum earum, negatio scilicet, est contraria. Et utrunque est verum. Illud quidem, quia, ut dictum est, ambae contrarietates oppositione contra affirmationem moliuntur; sed difformiter, quia opinio negationis primo et per se contrariatur, affirmationis vero contrarii opinio secundario et per accidens, idest per aliud, ratione scilicet negativae opinionis, ut declaratum est: sicut etiam in naturalibus albo contrariantur et nigrum et rubrum, sed illud primo, hoc reductive, ut reducitur scilicet ad nigrum illud inducendo, ut dicitur V Physic. Secundum autem dictum simpliciter verum est, quoniam simpliciter contraria non sunt nisi extrema unius latitudinis, quae maxime distant; extrema autem unius distantiae non sunt nisi duo. Et ideo cum inter pertinentes ad se invicem opiniones unum extremum teneat affirmatio vera, reliquum uni tantum falsae dandum est, illi scilicet quae maxime a vera distat. Hanc autem negativam opinionem esse probatum est. Haec igitur una tantum contraria est illi, simpliciter loquendo. Caeterae enim oppositae ratione istius contrariantur, ut de mediis dictum est. Non ergo uni plura contraria posuit, nec de contrarietate large loquutus est, ut obiiciendo dicebatur.
The answer to the third difficulty is the following. Since there is no other opposition but contrariety between opinions pertaining to each other, Aristotle (since he chose to use limited terms) has been forced to say that one is more contrary than another, which implies that both have opposition of contrariety in respect to a true opinion. However, he determines immediately that only one of them, the negative opinion, is contrary to a true affirmation, when he adds, it is evident that it must be the contrary (23b15). What he says, then, is that each, i.e., both negation of the same thing and affirmation of a contrary, is contrary to a true affirmation, and that only one of them, i.e., the negation, is contrary. Both of these statements are true, for both contrarieties are caused by an opposition contrary to the affirmation, as was said, but not uniformly. The opinion of negation is contrary first and per se, the opinion of affirmation of a contrary, secondarily and accidentally, i.e., through another, namely, by reason of the negative opinion, as has already been shown. There is a parallel to this in natural things: both black and red are contrary to white, the former first, the latter reductively, i.e., inasmuch as red is reduced to black in a motion from white to red, as is said in Physics 5.5 (229b15). However, the second statement, i.e., that only one of them, the negation, is contrary, is true simply, for the most distant extremes of one extent are contraries absolutely. Nov,, there are only two extremes of one distance and since between opinions pertaining to each other true affirmation is at one extreme, the remaining extreme must be granted to only one false opinion, i.e., to the one that is most distant from the true opinion. This has been proved to be the negative opinion. Only this one, then, is contrary to that absolutely speaking. Other opposites are contrary by reason of this one, as was said of those in between. Therefore, Aristotle has not posited many opinions contrary to one, nor used contrariety in a broad sense, both of which were maintained by the objector.
Peri.L14
371. Deinde cum dicit: amplius si etiam etc., probat idem, scilicet quod affirmationi contraria est negatio eiusdem, et non affirmatio contrarii secunda ratione, dicens: si in aliis materiis oportet opiniones se habere similiter, idest, eodem modo, ita quod contrariae in aliis materiis sunt affirmatio et negatio eiusdem; et hoc, scilicet quod diximus de boni et mali opinionibus, videtur esse bene dictum, quod scilicet contraria affirmationi boni non est affirmatio mali, sed negatio boni.
When Aristotle says, further, if this necessarily holds (23b27), he gives the second argument to prove that the negation of the same thing is contrary to the affirmation, and not the affirmation of a contrary. If opinions are necessarily related in a similar way (that is, in the same way) in other matters, that is, in such a way that affirmation and negation of the same thing are contraries in other matter, it would seem that what we have said about the opinions of that which is good and that which is evil is correct, namely, that the contrary of the affirmation of that which is good is not the affirmation of evil but the negation of good.
Peri.L14
Et probat hanc consequentiam subdens: aut enim ubique, idest, in omni materia, ea quae est contradictionis altera pars censenda est contraria suae affirmationi, aut nusquam, idest, aut in nulla materia. Si enim est una ars generalis accipiendi contrariam opinionem, oportet quod ubique et in omni materia uno et eodem modo accipiatur contraria opinio. Et consequenter, si in aliqua materia negatio eiusdem de eodem affirmationi est contraria, in omni materia negatio eiusdem de eodem contraria erit affirmationi.
He proves this consequence when he adds: for the opposition of contradiction either holds everywhere or nowhere (23b27), that is, in every matter one part of a contradiction must be judged contrary to its affirmation—or nowhere, that is, in no matter. For if there is a general art which deals with contrary opinions, contrary opinions must be taken everywhere and in every matter in one and the same mode. Consequently, if in any matter, negation of the same thing of the same thing is the contrary of the affirmation, then in all matter negation of the same thing of the same thing will be the contrary of the affirmation.
Peri.L14
Deinde intendens concludere a positione antecedentis, affirmat antecedens ex sua causa, dicens quod illae materiae quibus non inest contrarium, ut substantia et quantitas, quibus, ut in praedicamentis dicitur, nihil est contrarium. De his quidem est per se falsa ea, quae est opinioni verae opposita contradictorie, ut qui putat hominem, puta Socratem non esse hominem, per se falsus est respectu putantis, Socratem esse hominem.
Since he intends in his proof to conclude from the position of the antecedent, Aristotle affirms the antecedent through its cause: in matter in which there is not a contrary, such as substance and quantity (which have no contraries, as is said in Categories 5 [3b24] and 6 [5b10]), the one contradictorily opposed to the true opinion is per se false. For example, he who thinks that a man such as Socrates is not a man is per se mistaken with regard to one who thinks that Socrates is a man.
Peri.L14
Deinde affirmando ipsum antecedens formaliter, directe concludit intentum a positione antecedentis ad positionem consequentis dicens: si ergo hae, scilicet, affirmatio et negatio in materia carente contrario, sunt contrariae, et omnes aliae contradictiones contrariae censendae sunt.
Then he affirms the antecedent formally and concludes directly from the position of the antecedent to the position of the consequent. If, then, these (23b27), namely, affirmation and negation in matter which lacks a contrary, are contraries, all other contradictions must be judged to be contraries.
Peri.L14
372. Deinde cum dicit: amplius similiter etc., probat idem tertia ratione, quae talis est: sic se habent istae duae opiniones de bono, scilicet, bonum est bonum, et, bonum non est bonum, sicut se habent istae duae de non bono, scilicet, non bonum non est bonum, et, non bonum est bonum. Utrobique enim salvatur oppositio contradictionis. Et primae utriusque combinationis sunt verae, secundae autem falsae. Unde proponens hanc maiorem quoad primas veras utriusque combinationis ait: similiter se habet opinio boni, quoniam bonum est, et non boni quoniam non est bonum. Et subdit quoad secundas utriusque falsas: et super has opinio boni quoniam non est bonum, et non boni quoniam est bonum. Haec est maior.
When he says, again, the opinions of that which is good (23b33), he begins the third argument to prove the same thing. The two opinions of that which is good—that it is good, and that it is not good—are related in the same way as the two opinions of that which is not good—that it is not good and that it is good—namely, the opposition of contradiction is kept in both. The first opinion of each combination is true, the second false. Hence with respect to the first true opinions of each combination he proposes this major: again, the opinions of that which is good, that it is good, and of that which is not good, that it is not good, are parallel. With respect to the second false judgment of each combination he adds: so also are the opinions of that which is good, that it is not good, and of that which is not good, that it is good. This is the major.
Peri.L14
Sed illi verae opinioni de non bono, scilicet, non bonum non est bonum, contraria non est, non bonum est malum, nec bonum non est malum, quae sunt de praedicato contrario, sed illa, non bonum est bonum, quae est eius contradictoria; ergo et illi verae opinioni de bono, scilicet, bonum est bonum, contraria erit sua contradictoria, scilicet, bonum non est bonum, et non affirmatio contrarii, scilicet, bonum est malum. Unde subdit minorem supradictam dicens: illi ergo verae opinioni non boni, quae est dicens quoniam scilicet non bonum non est bonum, quae est contraria.
But the contrary of the true opinion of that which is not good, namely, the true opinion “that which is not good is not good,” is not “that which is not good is evil,” nor “that which is not good is not evil,” which have a contrary predicate, but the opinion that that which is not good is good, which is its contradictory. Therefore, the contrary of the true opinion of that which is good, namely, the true opinion “that which is good is good,” will also be its contradictory, “that which is good is not good,” and not the affirmation of the contrary “that which is good is evil.” Hence he adds the minor which we have already stated: what, then, would be the contrary of the true opinion asserting that that which is not good is not good?
Peri.L14
Non enim est sibi contraria ea opinio, quae dicit affirmativae praedicatum contrarium, scilicet, quod non bonum est malum: quia istae duae aliquando erunt simul verae. Nunquam autem vera opinio verae contraria est. Quod autem istae duae aliquando simul sint verae, patet ex hoc quod quoddam non bonum malum est: iniustitia enim quoddam non bonum est, et malum. Quare contingeret contrarias esse simul veras: quod est impossibile. At vero nec supradictae verae opinioni contraria est illa opinio, quae est dicens praedicatum contrarium negativae, scilicet, non bonum non est malum, eadem ratione, quia simul et hae erunt verae. Chimaera enim est quoddam non bonum, de qua verum est simul dicere quod non est bona, et quod non est mala.
The contrary of it is not the opinion which asserts the contrary predicate affirmatively, “that which is not good is evil,” because these two are sometimes at once true. But a true opinion is never contrary to a true opinion. That these two are sometimes at once true is evident from the fact that some things that are not good are evil. Take injustice; it is something not good, and it is evil. Therefore, contraries would be true at one and the same time, which is impossible. But neither is the contrary of the above true opinion the one asserting the contrary predicate negatively, “that which is not good is not evil,” and for the same reason. These will also be true at the same time. For example, a chimera is something not good, and it is true to say of it simultaneously that it is not good and that it is not evil.
Peri.L14
Relinquitur ergo tertia pars minoris quod ei opinioni verae quae, est dicens quoniam non bonum non est bonum, contraria est ea opinio non boni, quae est dicens quod est bonum, quae est contradictoria illius.
There remains the third part of the minor: the contrary of the true opinion that that which is not good is not good is the opinion that it is good, which is the contradictory of it.
Peri.L14
Deinde subdit conclusionem intentam: quare et ei opinioni boni, quae dicit bonum est bonum, contraria est ea boni opinio, quae dicit quod bonum non est bonum, idest, sua contradictoria. Contradictiones ergo contrariae in omni materia censendae sunt.
Then he concludes as he intended: the opinion that a good is not good is contrary to the opinion that a good is good, that is, its contradictory. Therefore, it must be judged that contradictions are contraries in every matter.
Peri.L14
373. Deinde cum dicit: manifestum est igitur etc., declarat determinatam veritatem extendi ad cuiusque quantitatis opiniones. Et quia de indefinitis, et particularibus, et singularibus iam dictum est, eo quod idem evidenter apparet de eis in hac re iudicium (indefinitae enim et particulares nisi pro eisdem supponant sicut singulares, per modum affirmationis et negationis non opponuntur, quia simul verae sunt); ideo ad eas, quae universalis quantitatis sunt se transfert, dicens, manifestum esse quod nihil interest quoad propositam quaestionem, si universaliter ponamus affirmationes. Huic enim, scilicet, universali affirmationi, contraria est universalis negatio, et non universalis affirmatio de contrario; ut opinioni quae opinatur, quoniam omne bonum est bonum, contraria est, nihil horum, quae bona sunt, idest, nullum bonum est bonum. Et declarat hoc ex quid nominis universalis affirmativae, dicens: nam eius quae est boni, quoniam bonum est, si universaliter sit bonum: idest, istius opinionis universalis, omne bonum est bonum, eadem est, idest, aequivalens, illa quae opinatur, quidquid est bonum est bonum; et consequenter sua negatio contraria est illa quam dixi, nihil horum quae bona sunt bonum est, idest, nullum bonum est bonum. Similiter autem se habet in non bono: quia affirmationi universali de non bono reddenda est negatio universalis eiusdem, sicut de bono dictum est.
When he says, it is evident that it will make no difference (24a3), he shows that the truth he has determined is extended to opinions of every quantity. The case has already been stated in respect to indefinites, particulars, and singulars. On this point their status is alike, for indefinites and particulars, unless they stand for the same thing, as is the case in singulars, are not opposed by way of affirmation and negation, since they are at once true. Therefore he turns his attention to those of universal quantity. It is evident, he says, that it will make no difference with respect to the proposed question if we posit the affirmations universally, for the contrary of the universal affirmative is the universal negative, and not the universal affirmation of a contrary. For example, the contrary of the opinion that everything that is good is good is the opinion that nothing that is good (namely, no good) is good. He manifests this by the nominal definition of universal affirmative: for the opinion that that which is good is good, if the good is universal, that is, the universal opinion “Every good is good,” is the same, that is, is equivalent to the opinion that whatever is good is good. Consequently, its negation is the contrary I have stated, “nothing which is good is good,” that is, “no good is good.” The case is similar with respect to the not good. The universal negation of the not good is opposed to the universal affirmation of the not good, as we have stated with respect to the good.
Peri.L14
374. Deinde cum dicit: quare si in opinione sic se habet etc., revertitur ad respondendum quaestioni primo motae, terminata iam secunda, ex qua illa dependet.
When he says, if, therefore, this is the case with respect to opinion (24b1), he returns to the question first advanced, to reply to it, for he has now completed the second on which the first depends.
Peri.L14
Et circa hoc duo facit:
About this he does two things.
Peri.L14
quia primo respondet quaestioni;
First, he replies to the question;
Peri.L14
secundo, declarat quoddam dictum in praecedenti solutione; ibi: manifestum est autem quoniam et cetera.
second, he manifests a point in the solution of a preceding difficulty, at: it is evident, too, that true cannot be contrary to true (24b6; [378]).
Peri.L14
Circa primum duo facit.
About the first he does two things.
Peri.L14
Primo, directe respondet quaestioni, dicens: quare si in opinione sic se habet contrarietas, ut dictum est; et affirmationes et negationes quae sunt in voce, notae sunt eorum, idest, affirmationum et negationum quae sunt in anima; manifestum est quoniam affirmationi, idest, enunciationi affirmativae, contraria erit negatio circa idem, idest, enunciatio negativa eiusdem de eodem, et non enunciatio affirmativa contrarii. Et sic patet responsio ad primam quaestionem, qua quaerebatur, an enunciationi affirmativae contraria sit sua negativa, an affirmativa contraria. Responsum est enim quod negativa est contraria.
First, he replies directly to the question, saying, if, therefore, contrariety is such in the case of opinions (24b1), and affirmations and negations in vocal sound are signs of affirmations and negations in the soul, it is evident that the contrary of the affirmation, that is, of the affirmative enunciation, is the negation of the same subject. In other words, the negative enunciation of the same predicate of the same subject will be the contrary, and not the affirmative enunciation of a contrary. Thus the response to the first question—whether the contrary of the affirmative enunciation is its negative or the contrary affirmative—is clear. The answer is that the negative is the contrary.
Peri.L14
Secundo, dividit negationem contrariam affirmationi, idest, negationem universalem et contradictoriam, dicens: universalis, scilicet, negatio, affirmationi contraria est et cetera. Ut exemplariter dicatur, ei enunciationi universali affirmativae quae est, omne bonum est bonum, vel, omnis homo est bonus, contraria est universalis negativa, ea scilicet, nullum bonum est bonum, vel, nullus homo est bonus: singula singulis referendo. Contradictoria autem negatio, contraria illi universali affirmationi est, aut, non omnis homo est bonus, aut, non omne bonum est bonum, singulis singula similiter referendo. Et sic posuit utrunque divisionis membrum, et declaravit.
Second, he divides negation as it is contrary to affirmation, that is, into the universal negation and the contradictory: the universal negation, is contrary to the affirmation (24b1). In order to state this division by way of example he relates one enunciation to one enunciation: the contrary of the universal affirmative enunciation “every good is good” or “every man is good” is the universal negative “no good is good” or “no man is good.” Again, relating one to one, he says that the contradictory negation contrary to the universal affirmation is “not every man is good” or “not everything good is good.” Thus he posits both members of the division and makes the division evident.
Peri.L14
375. Sed est hic dubitatio non dissimulanda. Si enim affirmationi universali contraria est duplex negatio, universalis scilicet et contradictoria, vel uni duo sunt contraria, vel contrarietate large utitur Aristoteles: cuius oppositum supra declaravimus. Augetur et dubitatio: quia in praecedenti textu dixit Aristoteles quod, nihil interest si universalem negationem faciamus ita contrariam universali affirmationi, sicut singularem singulari. Et ita declinari non potest quin affirmationi universali duae sint negationes contrariae, eo modo quo hic loquitur de contrarietate Aristoteles.
A difficulty arises at this point which we cannot disregard. If the contrary of the universal affirmative is a twofold negation, namely, the universal and the contradictory, either there are two contraries to one affirmation or Aristotle is using “contrariety” in a broad sense, although we showed that this was not the case through of an earlier passage of the text. The difficulty is augmented by the fact that Aristotle said in the passage immediately preceding that it makes no difference if we take the universal negation as contrary to the universal affirmation, that is, as one of its negations. Hence, the conclusion cannot be avoided that in the mode in which Aristotle speaks of contrariety here, there are two contrary negations to the universal affirmative.
Peri.L14
376. Ad huius evidentiam notandum est quod, aliud est loqui de contrarietate quae est inter negationem alicuius universalis affirmativae in ordine ad affirmationem contrarii de eodem, et aliud est loqui de illamet universali negativa in ordine ad negationem eiusdem affirmativae contradictoriam. Verbi gratia: sint quatuor enunciationes, quarum nunc meminimus, scilicet, universalis affirmativa, contradictoria, universalis negativa, et universalis affirmatio contrarii, sic dispositae in eadem linea recta: omnis homo est iustus, non omnis homo est iustus, omnis homo non est iustus, omnis homo est iniustus: et intuere quod licet primae omnes reliquae aliquo modo contrarientur, magna tamen differentia est inter primae et cuiusque earum contrarietatem.
To clear up this difficulty we must note that it is one thing to speak of the contrariety between the negation of some universal affirmative in relation to the affirmation of a contrary, and another to speak of that same universal negative in relation to the negation contradictory to the same affirmative. For example, the four enunciations of which we are now speaking are the universal affirmative, the contradictory, the universal negative, and the universal affirmation of a contrary: “every man is just,” “not every man is just,” “no man is just,” “every man is unjust.” Notice that although all the rest are contrary to the first in some way, there is a great difference between the contrariety of each to the first.
Peri.L14
Ultima enim, scilicet affirmatio contrarii, primae contrariatur ratione universalis negationis, quae ante ipsam sita est: quia non per se sed ratione illius falsa est, ut probavit Aristoteles, quia implicita est.
The last one, the affirmation of a contrary, is contrary to the first by reason of the preceding universal negation, for it is false not per se, but by reason of that negation, that is, it is implicative, as Aristotle has already proved.
Peri.L14
Tertia autem, idest universalis negatio, non per se sed ratione secundae, scilicet negationis contradictoriae, contrariatur primae eadem ratione, quia, scilicet, non est per se falsa illius affirmationis veritate, sed implicita: continet enim negationem contradictoriam, scilicet, non omnis homo est iustus, mediante qua falsificatur ab affirmationis veritate, quia simpliciter et prior est falsitas negationis contradictoriae falsitate negationis universalis: totum namque compositius et posterius est partibus. Est ergo inter has tres falsas ordo.
The third, the universal negation, is not per se contrary to the first either. It is contrary by reason of the second, the contradictory negation, and for the same reason, namely, it is not per se false in respect to the truth of the affirmation but is implicative, for it contains the contradictory negation “not every man is just,” by means of which it is made false in respect to the truth of the affirmation. The reason for this is that the falsity of the contradictory negation is prior absolutely to the falsity of the universal negation, for the whole is more composite and posterior as compared to its parts. There is, therefore, an order among these three false enunciations.
Peri.L14
Ita quod affirmationi verae contradictoria negatio simpliciter sola est contraria, quia est simpliciter respectu illius per se falsa; affirmativa autem contrarii est per accidens contraria, quia est per accidens falsa; universalis vero negatio, tamquam medium sapiens utriusque extremi naturam, relata ad contrarii affirmationem est per se contraria et per se falsa, relata autem ad negationem contradictoriam est per accidens falsa et contraria. Sicut rubrum ad nigrum est album, et ad album est nigrum, ut dicitur in V physicorum. Aliud igitur est loqui de negatione universali in ordine ad affirmationem contrarii, et aliud in ordine ad negationem contradictoriam. Si enim primo modo loquamur, sic negatio universalis per se contraria et per se falsa est; si autem secundo modo, non est per se falsa, nec contraria affirmationi.
Only the contradictory negation is simply contrary to the true affirmation, for it is per se false simply in respect to the affirmation; the affirmative of the contrary is per accidens contrary, since it is per accidens false; the universal negation, which is a medium partaking of the nature of each extreme, is per se contrary and per se false as related to the affirmation of a contrary, but is per accidens false and per accidens contrary as related to the contradictory negation; just as red in a motion from red to black takes the place of white, and in a motion from red to white takes the place of black, as is said in Physics 5.5 (229b15). Therefore, it is one thing to speak of the universal negation in relation to affirmation of a contrary and another to speak of it in relation to the contradictory negation. If we are speaking of it in the first way, the universal negation is per se contrary and per se false; if in the second, it is not per se false or contrary to the affirmation.
Peri.L14
377. Quia ergo agitur ab Aristotele nunc quaestio, inter affirmationem contrarii et negationem quae earum contraria sit affirmationi verae, et non agitur quaestio ipsarum negationum inter se, quae, scilicet, earum contraria sit illi affirmationi, ut patet in toto processu quaestionis; ideo Aristoteles indistincte dixit quod utraque negatio est contraria affirmationi verae, et non affirmatio contrarii. Intendens per hoc declarare diversitatem quae est inter affirmationem contrarii et negationem in hoc quod verae affirmationi contrariantur, et non intendens dicere quod utraque negatio est simpliciter contraria. Hoc enim in dubitatione non est quaesitum, sed illud tantum.
Since Aristotle is now treating the question of whether the contrary of a true affirmation is the affirmation of a contrary or the negation, and not the question as to which of the negations is contrary to a true affirmation—as is clear in the whole progression of the question—his answer is that both negations are contrary to the true affirmation without distinction, and that affirmation of a contrary is not. His intention is to manifest the diversity between the negation and the affirmation of a contrary inasmuch as they are contrary to a true affirmation. He does not intend to say that both negations are contrary simply, for this is not the difficulty in question here, but the former is.
Peri.L14
Et similiter dixit quod nihil interest si quis ponat negationem universalem: nihil enim interest quoad hoc, quod affirmatio contrarii ostendatur non contraria affirmationi verae, quod inquirimus. Plurimum autem interesset, si negationes ipsas inter se discutere vellemus quae earum esset affirmationi contraria. Sic ergo patet quod subtilissime Aristoteles locutus de vera contrarietate enunciationum, unam uni contrariam posuit in omni materia et quantitate, dum simpliciter contrarias contradictiones asseruit.
With respect to his saying that it makes no difference if we posit the universal negation, the same point applies, for in regard to showing that affirmation of a contrary is not contrary to a true affirmation, which is the question at issue here, it makes no difference which negation is posited. It would make a great deal of difference, however, if we wished to discuss which negation was contrary to a true affirmation. It is evident, then, that Aristotle’s discussion of the true contrariety of enunciations is very subtle, for he has posited one to one contraries in every matter and quantity, and affirmed that contradictions are contraries simply.
Peri.L14
378. Deinde cum dicit: manifestum est autem etc., resumit quoddam dictum ut probet illud, dicens manifestum est autem ex dicendis quod non contingit veram verae contrariam esse, nec in opinione mentali, nec in contradictione, idest, vocali enunciatione. Et causam subdit: quia contraria sunt quae circa idem opposita sunt; et consequenter enunciationes et opiniones verae circa diversa contrariae esse non possunt. Circa idem autem contingit simul omnes veras enunciationes et opiniones verificari, sicut et significata vel repraesentata earum simul illi insunt: aliter verae tunc non sunt. Et consequenter omnes verae enunciationes et opiniones circa idem contrariae non sunt, quia contraria non contingit eidem simul inesse. Nullum ergo verum sive sit circa idem, sive sit circa aliud, est alteri vero contrarium.
When he says, it is evident, too, that true cannot be contrary to true (24b6), he returns to a statement he has already made in order to prove it. It is evident, too, from what has been said, that true cannot be contrary to true, either in mental opinion or in contradiction, that is, in vocal enunciation. He gives as the cause of this that contraries are opposites about the same thing; consequently, true enunciations and opinions about diverse things cannot be contraries. However, it is possible for all true enunciations and opinions about the same thing to be verified at the same time, inasmuch as the things signified or represented by them belong to the same thing at the same time; otherwise, they are not true. Consequently, not all true enunciations and opinions about the same thing are contraries, for it is not possible for contraries to be in the same thing at the same time. Therefore, no true opinion or enunciation, whether it is about the same thing or is about another, is contrary to another.

Et sic finitur expositio huius libri Perihermenias. Anno nativitatis dominicae 1496, in festo divi Thomae Aquinatis. Cui sit honor et gloria, eo quod dederit opus a se inceptum, tanto tempore incompletum, perfici.
We conclude the commentary on this book Peri Hermenias, 1496 A.D., on the feast of St. Thomas Aquinas. Glory and honor to God for allowing me to bring this work, so long left unfinished, to completion.
