||<b>IЄ q. 84 pr. </b>Consequenter considerandum est de actibus animae, quantum ad potentias intellectivas et appetitivas, aliae enim animae potentiae non pertinent directe ad considerationem theologi. Actus autem appetitivae partis ad considerationem moralis scientiae pertinent, et ideo in secunda parte huius operis de eis tractabitur, in qua considerandum erit de morali materia. Nunc autem de actibus intellectivae partis agetur. In consideratione vero actuum, hoc modo procedemus, primo namque considerandum est quomodo intelligit anima corpori coniuncta; secundo, quomodo intelligit a corpore separata. Prima autem consideratio erit tripartita, primo namque considerabitur quomodo anima intelligit corporalia, quae sunt infra ipsam; secundo, quomodo intelligit seipsam, et ea quae in ipsa sunt; tertio, quomodo intelligit substantias immateriales, quae sunt supra ipsam. Circa cognitionem vero corporalium, tria consideranda occurrunt, primo quidem per quid ea cognoscit; secundo, quomodo et quo ordine; tertio, quid in eis cognoscit. Circa primum quaeruntur octo. Primo, utrum anima cognoscat corpora per intellectum. Secundo, utrum intelligat ea per essentiam suam, vel per aliquas species. Tertio, si per aliquas species, utrum species omnium intelligibilium sint ei naturaliter innatae. Quarto, utrum effluant in ipsam ab aliquibus formis immaterialibus separatis. Quinto, utrum anima nostra omnia quae intelligit, videat in rationibus aeternis. Sexto, utrum cognitionem intelligibilem acquirat a sensu. Septimo, utrum intellectus possit actu intelligere per species intelligibiles quas penes se habet, non convertendo se ad phantasmata. Octavo, utrum iudicium intellectus impediatur per impedimentum sensitivarum virtutum. ||

||<b>IЄ q. 84 a. 1 arg. 1 </b>Ad primum sic proceditur. Videtur quod anima non cognoscat corpora per intellectum. Dicit enim Augustinus, in II Soliloq. quod corpora intellectu comprehendi non possunt; nec aliquod corporeum nisi sensibus videri potest. Dicit etiam, XII super Gen. ad Litt., quod visio intellectualis est eorum quae sunt per essentiam suam in anima. Huiusmodi autem non sunt corpora. Ergo anima per intellectum corpora cognoscere non potest. ||Objection 1. It would seem that the soul does not know bodies through the intellect. For Augustine says (Soliloq. ii, 4) that "bodies cannot be understood by the intellect; nor indeed anything corporeal unless it can be perceived by the senses." He says also (Gen. ad lit. xii, 24) that intellectual vision is of those things that are in the soul by their essence. But such are not bodies. Therefore the soul cannot know bodies through the intellect.

||<b>IЄ q. 84 a. 1 arg. 2 </b>Praeterea, sicut se habet sensus ad intelligibilia, ita se habet intellectus ad sensibilia. Sed anima per sensum nullo modo potest cognoscere spiritualia, quae sunt intelligibilia. Ergo nullo modo per intellectum potest cognoscere corpora, quae sunt sensibilia. ||Objection 2. Further, as sense is to the intelligible, so is the intellect to the sensible. But the soul can by no means, through the senses, understand spiritual things, which are intelligible. Therefore by no means can it, through the intellect, know bodies, which are sensible.

||<b>IЄ q. 84 a. 1 arg. 3 </b>Praeterea, intellectus est necessariorum et semper eodem modo se habentium. Sed corpora omnia sunt mobilia, et non eodem modo se habentia. Anima ergo per intellectum corpora cognoscere non potest. ||Objection 3. Further, the intellect is concerned with things that are necessary and unchangeable. But all bodies are mobile and changeable. Therefore the soul cannot know bodies through the intellect.

||<b>IЄ q. 84 a. 1 s. c. </b>Sed contra est quod scientia est in intellectu. Si ergo intellectus non cognoscit corpora, sequitur quod nulla scientia sit de corporibus. Et sic peribit scientia naturalis, quae est de corpore mobili. ||On the contrary, Science is in the intellect. If, therefore, the intellect does not know bodies, it follows that there is no science of bodies; and thus perishes natural science, which treats of mobile bodies.

||<b>IЄ q. 84 a. 1 co. </b>Respondeo dicendum, ad evidentiam huius quaestionis, quod primi philosophi qui de naturis rerum inquisiverunt, putaverunt nihil esse in mundo praeter corpus. Et quia videbant omnia corpora mobilia esse, et putabant ea in continuo fluxu esse, aestimaverunt quod nulla certitudo de rerum veritate haberi posset a nobis. Quod enim est in continuo fluxu, per certitudinem apprehendi non potest, quia prius labitur quam mente diiudicetur, sicut Heraclitus dixit quod non est possibile aquam fluvii currentis bis tangere, ut recitat philosophus in IV Metaphys. His autem superveniens Plato, ut posset salvare certam cognitionem veritatis a nobis per intellectum haberi, posuit praeter ista corporalia aliud genus entium a materia et motu separatum, quod nominabat species sive ideas, per quarum participationem unumquodque istorum singularium et sensibilium dicitur vel homo vel equus vel aliquid huiusmodi. Sic ergo dicebat scientias et definitiones et quidquid ad actum intellectus pertinet, non referri ad ista corpora sensibilia, sed ad illa immaterialia et separata; ut sic anima non intelligat ista corporalia, sed intelligat horum corporalium species separatas. Sed hoc dupliciter apparet falsum. Primo quidem quia, cum illae species sint immateriales et immobiles, excluderetur a scientiis cognitio motus et materiae (quod est proprium scientiae naturalis) et demonstratio per causas moventes et materiales. Secundo autem, quia derisibile videtur ut, dum rerum quae nobis manifestae sunt notitiam quaerimus, alia entia in medium afferamus, quae non possunt esse earum substantiae, cum ab eis differant secundum esse, et sic, illis substantiis separatis cognitis, non propter hoc de istis sensibilibus iudicare possemus. Videtur autem in hoc Plato deviasse a veritate, quia, cum aestimaret omnem cognitionem per modum alicuius similitudinis esse, credidit quod forma cogniti ex necessitate sit in cognoscente eo modo quo est in cognito. Consideravit autem quod forma rei intellectae est in intellectu universaliter et immaterialiter et immobiliter, quod ex ipsa operatione intellectus apparet, qui intelligit universaliter et per modum necessitatis cuiusdam; modus enim actionis est secundum modum formae agentis. Et ideo existimavit quod oporteret res intellectas hoc modo in seipsis subsistere, scilicet immaterialiter et immobiliter. Hoc autem necessarium non est. Quia etiam in ipsis sensibilibus videmus quod forma alio modo est in uno sensibilium quam in altero, puta cum in uno est albedo intensior, in alio remissior, et in uno est albedo cum dulcedine, in alio sine dulcedine. Et per hunc etiam modum forma sensibilis alio modo est in re quae est extra animam, et alio modo in sensu, qui suscipit formas sensibilium absque materia, sicut colorem auri sine auro. Et similiter intellectus species, corporum, quae sunt materiales et mobiles, recipit immaterialiter et immobiliter, secundum modum suum, nam receptum est in recipiente per modum recipientis. Dicendum est ergo quod anima per intellectum cognoscit corpora cognitione immateriali, universali et necessaria. ||I answer that, It should be said in order to elucidate this question, that the early philosophers, who inquired into the natures of things, thought there was nothing in the world save bodies. And because they observed that all bodies are mobile, and considered them to be ever in a state of flux, they were of opinion that we can have no certain knowledge of the true nature of things. For what is in a continual state of flux, cannot be grasped with any degree of certitude, for it passes away ere the mind can form a judgment thereon: according to the saying of Heraclitus, that "it is not possible twice to touch a drop of water in a passing torrent," as the Philosopher relates (Metaph. iv, Did. iii, 5).  After these came Plato, who, wishing to save the certitude of our knowledge of truth through the intellect, maintained that, besides these things corporeal, there is another genus of beings, separate from matter and movement, which beings he called "species" or "ideas," by participation of which each one of these singular and sensible things is said to be either a man, or a horse, or the like. Wherefore he said that sciences and definitions, and whatever appertains to the act of the intellect, are not referred to these sensible bodies, but to those beings immaterial and separate: so that according to this the soul does not understand these corporeal things, but the separate species thereof.  Now this may be shown to be false for two reasons. First, because, since those species are immaterial and immovable, knowledge of movement and matter would be excluded from science (which knowledge is proper to natural science), and likewise all demonstration through moving and material causes. Secondly, because it seems ridiculous, when we seek for knowledge of things which are to us manifest, to introduce other beings, which cannot be the substance of those others, since they differ from them essentially: so that granted that we have a knowledge of those separate substances, we cannot for that reason claim to form a judgment concerning these sensible things. Now it seems that Plato strayed from the truth because, having observed that all knowledge takes place through some kind of similitude, he thought that the form of the thing known must of necessity be in the knower in the same manner as in the thing known. Then he observed that the form of the thing understood is in the intellect under conditions of universality, immateriality, and immobility: which is apparent from the very operation of the intellect, whose act of understanding has a universal extension, and is subject to a certain amount of necessity: for the mode of action corresponds to the mode of the agent's form. Wherefore he concluded that the things which we understand must have in themselves an existence under the same conditions of immateriality and immobility. But there is no necessity for this. For even in sensible things it is to be observed that the form is otherwise in one sensible than in another: for instance, whiteness may be of great intensity in one, and of a less intensity in another: in one we find whiteness with sweetness, in another without sweetness. In the same way the sensible form is conditioned differently in the thing which is external to the soul, and in the senses which receive the forms of sensible things without receiving matter, such as the color of gold without receiving gold. So also the intellect, according to its own mode, receives under conditions of immateriality and immobility, the species of material and mobile bodies: for the received is in the receiver according to the mode of the receiver. We must conclude, therefore, that through the intellect the soul knows bodies by a knowledge which is immaterial, universal, and necessary.

||<b>IЄ q. 84 a. 1 ad 1 </b>Ad primum ergo dicendum quod verbum Augustini est intelligendum quantum ad ea quibus intellectus cognoscit, non autem quantum ad ea quae cognoscit. Cognoscit enim corpora intelligendo, sed non per corpora, neque per similitudines materiales et corporeas; sed per species immateriales et intelligibiles, quae per sui essentiam in anima esse possunt. ||Reply to Objection 1. These words of Augustine are to be understood as referring to the medium of intellectual knowledge, and not to its object. For the intellect knows bodies by understanding them, not indeed through bodies, nor through material and corporeal species; but through immaterial and intelligible species, which can be in the soul by their own essence.

||<b>IЄ q. 84 a. 1 ad 2 </b>Ad secundum dicendum quod, sicut Augustinus dicit XXII de Civit. Dei, non est dicendum quod, sicut sensus cognoscit sola corporalia, ita intellectus cognoscit sola spiritualia, quia sequeretur quod Deus et Angeli corporalia non cognoscerent. Huius autem diversitatis ratio est, quia inferior virtus non se extendit ad ea quae sunt superioris virtutis; sed virtus superior ea quae sunt inferioris virtutis, excellentiori modo operatur. ||Reply to Objection 2. As Augustine says (De Civ. Dei xxii, 29), it is not correct to say that as the sense knows only bodies so the intellect knows only spiritual things; for it follows that God and the angels would not know corporeal things. The reason of this diversity is that the lower power does not extend to those things that belong to the higher power; whereas the higher power operates in a more excellent manner those things which belong to the lower power.

||<b>IЄ q. 84 a. 1 ad 3 </b>Ad tertium dicendum quod omnis motus supponit aliquid immobile, cum enim transmutatio fit secundum qualitatem, remanet substantia immobilis; et cum transmutatur forma substantialis, remanet materia immobilis. Rerum etiam mutabilium sunt immobiles habitudines, sicut Socrates etsi non semper sedeat, tamen immobiliter est verum quod, quandocumque sedet, in uno loco manet. Et propter hoc nihil prohibet de rebus mobilibus immobilem scientiam habere. ||Reply to Objection 3. Every movement presupposes something immovable: for when a change of quality occurs, the substance remains unmoved; and when there is a change of substantial form, matter remains unmoved. Moreover the various conditions of mutable things are themselves immovable; for instance, though Socrates be not always sitting, yet it is an immovable truth that whenever he does sit he remains in one place. For this reason there is nothing to hinder our having an immovable science of movable things.

||<b>IЄ q. 84 a. 2</b> ||Whether the soul understands corporeal things through its essence?
 
|- valign = top
 
||<b>IЄ q. 84 a. 2 arg. 1 </b>Ad secundum sic proceditur. Videtur quod anima per essentiam suam corporalia intelligat. Dicit enim Augustinus, X de Trin., quod anima imagines corporum convolvit et rapit factas in semetipsa de semetipsa, dat enim eis formandis quiddam substantiae suae. Sed per similitudines corporum corpora intelligit. Ergo per essentiam suam, quam dat formandis talibus similitudinibus, et de qua eas format, cognoscit corporalia. ||Objection 1. It would seem that the soul understands corporeal things through its essence. For Augustine says (De Trin. x, 5) that the soul "collects and lays hold of the images of bodies which are formed in the soul and of the soul: for in forming them it gives them something of its own substance." But the soul understands bodies by images of bodies. Therefore the soul knows bodies through its essence, which it employs for the formation of such images, and from which it forms them.

||<b>IЄ q. 84 a. 2 arg. 2 </b>Praeterea, philosophus dicit, in III de anima, quod anima quodammodo est omnia. Cum ergo simile simili cognoscatur, videtur quod anima per seipsam corporalia cognoscat. ||Objection 2. Further, the Philosopher says (De Anima iii, 8) that "the soul, after a fashion, is everything." Since, therefore, like is known by like, it seems that the soul knows corporeal things through itself.

||<b>IЄ q. 84 a. 2 arg. 3 </b>Praeterea, anima est superior corporalibus creaturis. Inferiora autem sunt in superioribus eminentiori modo quam in seipsis, ut Dionysius dicit. Ergo omnes creaturae corporeae nobiliori modo existunt in ipsa substantia animae quam in seipsis. Per suam ergo substantiam potest creaturas corporeas cognoscere. ||Objection 3. Further, the soul is superior to corporeal creatures. Now lower things are in higher things in a more eminent way than in themselves, as Dionysius says (Coel. Hier. xii). Therefore all corporeal creatures exist in a more excellent way in the soul than in themselves. Therefore the soul can know corporeal creatures through its essence.

||<b>IЄ q. 84 a. 2 s. c. </b>Sed contra est quod Augustinus dicit, IX de Trin., quod mens corporearum rerum notitias per sensus corporis colligit. Ipsa autem anima non est cognoscibilis per corporis sensus. Non ergo cognoscit corporea per suam substantiam. ||On the contrary, Augustine says (De Trin. ix, 3) that "the mind gathers knowledge of corporeal things through the bodily senses." But the soul itself cannot be known through the bodily senses. Therefore it does not know corporeal things through itself.

||<b>IЄ q. 84 a. 2 co. </b>Respondeo dicendum quod antiqui philosophi posuerunt quod anima per suam essentiam cognoscit corpora. Hoc enim animis omnium communiter inditum fuit, quod simile simili cognoscitur. Existimabant autem quod forma cogniti sit in cognoscente eo modo quo est in re cognita. E contrario tamen Platonici posuerunt. Plato enim, quia perspexit intellectualem animam immaterialem esse et immaterialiter cognoscere, posuit formas rerum cognitarum immaterialiter subsistere. Priores vero naturales, quia considerabant res cognitas esse corporeas et materiales, posuerunt oportere res cognitas etiam in anima cognoscente materialiter esse. Et ideo, ut animae attribuerent omnium cognitionem, posuerunt eam habere naturam communem cum omnibus. Et quia natura principiatorum ex principiis constituitur, attribuerunt animae naturam principii, ita quod qui dixit principium omnium esse ignem, posuit animam esse de natura ignis; et similiter de aere et aqua. Empedocles autem, qui posuit quatuor elementa materialia et duo moventia, ex his etiam dixit animam esse constitutam. Et ita, cum res materialiter in anima ponerent, posuerunt omnem cognitionem animae materialem esse, non discernentes inter intellectum et sensum. Sed haec opinio improbatur. Primo quidem, quia in materiali principio, de quo loquebantur, non existunt principiata nisi in potentia. Non autem cognoscitur aliquid secundum quod est in potentia, sed solum secundum quod est actu, ut patet in IX Metaphys., unde nec ipsa potentia cognoscitur nisi per actum. Sic igitur non sufficeret attribuere animae principiorum naturam ad hoc quod omnia cognosceret, nisi inessent ei naturae et formae singulorum effectuum, puta ossis et carnis et aliorum huiusmodi; ut Aristoteles contra Empedoclem argumentatur in I de anima. Secundo quia, si oporteret rem cognitam materialiter in cognoscente existere, nulla ratio esset quare res quae materialiter extra animam subsistunt, cognitione carerent, puta, si anima igne cognoscit ignem, et ignis etiam qui est extra animam, ignem cognosceret. Relinquitur ergo quod oportet materialia cognita in cognoscente existere non materialiter, sed magis immaterialiter. Et huius ratio est, quia actus cognitionis se extendit ad ea quae sunt extra cognoscentem, cognoscimus enim etiam ea quae extra nos sunt. Per materiam autem determinatur forma rei ad aliquid unum. Unde manifestum est quod ratio cognitionis ex opposito se habet ad rationem materialitatis. Et ideo quae non recipiunt formas nisi materialiter, nullo modo sunt cognoscitiva, sicut plantae; ut dicitur in II libro de anima. Quanto autem aliquid immaterialius habet formam rei cognitae, tanto perfectius cognoscit. Unde et intellectus, qui abstrahit speciem non solum a materia, sed etiam a materialibus conditionibus individuantibus, perfectius cognoscit quam sensus, qui accipit formam rei cognitae sine materia quidem, sed cum materialibus conditionibus. Et inter ipsos sensus, visus est magis cognoscitivus, quia est minus materialis, ut supra dictum est. Et inter ipsos intellectus, tanto quilibet est perfectior, quanto immaterialior. Ex his ergo patet quod, si aliquis intellectus est qui per essentiam suam cognoscit omnia, oportet quod essentia eius habeat in se immaterialiter omnia; sicut antiqui posuerunt essentiam animae actu componi ex principiis omnium materialium, ut cognosceret omnia. Hoc autem est proprium Dei, ut sua essentia sit immaterialiter comprehensiva omnium, prout effectus virtute praeexistunt in causa. Solus igitur Deus per essentiam suam omnia intelligit; non autem anima humana, neque etiam Angelus. ||I answer that, The ancient philosophers held that the soul knows bodies through its essence. For it was universally admitted that "like is known by like." But they thought that the form of the thing known is in the knower in the same mode as in the thing known. The Platonists however were of a contrary opinion. For Plato, having observed that the intellectual soul has an immaterial nature, and an immaterial mode of knowledge, held that the forms of things known subsist immaterially. While the earlier natural philosophers, observing that things known are corporeal and material, held that things known must exist materially even in the soul that knows them. And therefore, in order to ascribe to the soul a knowledge of all things, they held that it has the same nature in common with all. And because the nature of a result is determined by its principles, they ascribed to the soul the nature of a principle; so that those who thought fire to be the principle of all, held that the soul had the nature of fire; and in like manner as to air and water. Lastly, Empedocles, who held the existence of our four material elements and two principles of movement, said that the soul was composed of these. Consequently, since they held that things exist in the soul materially, they maintained that all the soul's knowledge is material, thus failing to discern intellect from sense. But this opinion will not hold. First, because in the material principle of which they spoke, the various results do not exist save in potentiality. But a thing is not known according as it is in potentiality, but only according as it is in act, as is shown Metaph. ix (Did. viii, 9): wherefore neither is a power known except through its act. It is therefore insufficient to ascribe to the soul the nature of the principles in order to explain the fact that it knows all, unless we further admit in the soul natures and forms of each individual result, for instance, of bone, flesh, and the like; thus does Aristotle argue against Empedocles (De Anima i, 5). Secondly, because if it were necessary for the thing known to exist materially in the knower, there would be no reason why things which have a material existence outside the soul should be devoid of knowledge; why, for instance, if by fire the soul knows fire, that fire also which is outside the soul should not have knowledge of fire. We must conclude, therefore, that material things known must needs exist in the knower, not materially, but immaterially. The reason of this is, because the act of knowledge extends to things outside the knower: for we know things even that are external to us. Now by matter the form of a thing is determined to some one thing. Wherefore it is clear that knowledge is in inverse ratio of materiality. And consequently things that are not receptive of forms save materially, have no power of knowledge whatever--such as plants, as the Philosopher says (De Anima ii, 12). But the more immaterially a thing receives the form of the thing known, the more perfect is its knowledge. Therefore the intellect which abstracts the species not only from matter, but also from the individuating conditions of matter, has more perfect knowledge than the senses, which receive the form of the thing known, without matter indeed, but subject to material conditions. Moreover, among the senses, sight has the most perfect knowledge, because it is the least material, as we have remarked above (78, 3): while among intellects the more perfect is the more immaterial. It is therefore clear from the foregoing, that if there be an intellect which knows all things by its essence, then its essence must needs have all things in itself immaterially; thus the early philosophers held that the essence of the soul, that it may know all things, must be actually composed of the principles of all material things. Now this is proper to God, that His Essence comprise all things immaterially as effects pre-exist virtually in their cause. God alone, therefore, understands all things through His Essence: but neither the human soul nor the angels can do so.

||<b>IЄ q. 84 a. 2 ad 1 </b>Ad primum ergo dicendum quod Augustinus ibi loquitur de visione imaginaria, quae fit per imagines corporum. Quibus imaginibus formandis dat anima aliquid suae substantiae, sicut subiectum datur ut informetur per aliquam formam. Et sic de seipsa facit huiusmodi imagines, non quod anima vel aliquid animae convertatur, ut sit haec vel illa imago; sed sicut dicitur de corpore fieri aliquid coloratum, prout informatur colore. Et hic sensus apparet ex his quae sequuntur. Dicit enim quod servat aliquid, scilicet non formatum tali imagine, quod libere de specie talium imaginum iudicet, et hoc dicit esse mentem vel intellectum. Partem autem quae informatur huiusmodi imaginibus scilicet imaginativam, dicit esse communem nobis et bestiis. ||Reply to Objection 1. Augustine in that passage is speaking of an imaginary vision, which takes place through the image of bodies. To the formation of such images the soul gives part of its substance, just as a subject is given in order to be informed by some form. In this way the soul makes such images from itself; not that the soul or some part of the soul be turned into this or that image; but just as we say that a body is made into something colored because of its being informed with color. That this is the sense, is clear from what follows. For he says that the soul "keeps something"--namely, not informed with such image--"which is able freely to judge of the species of these images": and that this is the "mind" or "intellect." And he says that the part which is informed with these images--namely, the imagination--is "common to us and beasts."

||<b>IЄ q. 84 a. 2 ad 2 </b>Ad secundum dicendum quod Aristoteles non posuit animam esse actu compositam ex omnibus, sicut antiqui naturales; sed dixit quodammodo animam esse omnia, inquantum est in potentia ad omnia; per sensum quidem ad sensibilia, per intellectum vero ad intelligibilia. ||Reply to Objection 2. Aristotle did not hold that the soul is actually composed of all things, as did the earlier philosophers; he said that the soul is all things, "after a fashion," forasmuch as it is in potentiality to all--through the senses, to all things sensible--through the intellect, to all things intelligible.

||<b>IЄ q. 84 a. 2 ad 3 </b>Ad tertium dicendum quod quaelibet creatura habet esse finitum et determinatum. Unde essentia superioris creaturae, etsi habeat quandam similitudinem inferioris creaturae prout communicant in aliquo genere, non tamen complete habet similitudinem illius, quia determinatur ad aliquam speciem, praeter quam est species inferioris creaturae. Sed essentia Dei est perfecta similitudo omnium quantum ad omnia quae in rebus inveniuntur, sicut universale principium omnium. ||Reply to Objection 3. Every creature has a finite and determinate essence. Wherefore although the essence of the higher creature has a certain likeness to the lower creature, forasmuch as they have something in common generically, yet it has not a complete likeness thereof, because it is determined to a certain species other than the species of the lower creature. But the Divine Essence is a perfect likeness of all, whatsoever may be found to exist in things created, being the universal principle of all.

||<b>IЄ q. 84 a. 3</b> ||Whether the soul understands all things through innate species?
 
|- valign = top
 
||<b>IЄ q. 84 a. 3 arg. 1 </b>Ad tertium sic proceditur. Videtur quod anima intelligat omnia per species sibi naturaliter inditas. Dicit enim Gregorius, in homilia ascensionis quod homo habet commune cum Angelis intelligere. Sed Angeli intelligunt omnia per formas naturaliter inditas, unde in libro de causis dicitur quod omnis intelligentia est plena formis. Ergo et anima habet species rerum naturaliter inditas, quibus corporalia intelligit. ||Objection 1. It would seem that the soul understands all things through innate species. For Gregory says, in a homily for the Ascension (xxix in Ev.), that "man has understanding in common with the angels." But angels understand all things through innate species: wherefore in the book De Causis it is said that "every intelligence is full of forms." Therefore the soul also has innate species of things, by means of which it understands corporeal things. 
 
|- valign = top
 
||<b>IЄ q. 84 a. 3 arg. 2 </b>Praeterea, anima intellectiva est nobilior quam materia prima corporalis. Sed materia prima est creata a Deo sub formis ad quas est in potentia. Ergo multo magis anima intellectiva est creata a Deo sub speciebus intelligibilibus. Et sic anima intelligit corporalia per species sibi naturaliter inditas. ||Objection 2. Further, the intellectual soul is more excellent than corporeal primary matter. But primary matter was created by God under the forms to which it has potentiality. Therefore much more is the intellectual soul created by God under intelligible species. And so the soul understands corporeal things through innate species.

||<b>IЄ q. 84 a. 3 arg. 3 </b>Praeterea, nullus potest verum respondere nisi de eo quod scit. Sed aliquis etiam idiota, non habens scientiam acquisitam, respondet verum de singulis, si tamen ordinate interrogetur, ut narratur in Menone Platonis de quodam. Ergo antequam aliquis acquirat scientiam, habet rerum cognitionem. Quod non esset nisi anima haberet species naturaliter inditas. Intelligit igitur anima res corporeas per species naturaliter inditas. ||Objection 3. Further, no one can answer the truth except concerning what he knows. But even a person untaught and devoid of acquired knowledge, answers the truth to every question if put to him in orderly fashion, as we find related in the Meno (xv seqq.) of Plato, concerning a certain individual. Therefore we have some knowledge of things even before we acquire knowledge; which would not be the case unless we had innate species. Therefore the soul understands corporeal things through innate species.

||<b>IЄ q. 84 a. 3 co. </b>Respondeo dicendum quod, cum forma sit principium actionis, oportet ut eo modo se habeat aliquid ad formam quae est actionis principium, quo se habet ad actionem illam, sicut si moveri sursum est ex levitate, oportet quod in potentia tantum sursum fertur, esse leve solum in potentia, quod autem actu sursum fertur, esse leve in actu. Videmus autem quod homo est quandoque cognoscens in potentia tantum, tam secundum sensum quam secundum intellectum. Et de tali potentia in actum reducitur, ut sentiat quidem, per actiones sensibilium in sensum; ut intelligat autem, per disciplinam aut inventionem. Unde oportet dicere quod anima cognoscitiva sit in potentia tam ad similitudines quae sunt principia sentiendi, quam ad similitudines quae sunt principia intelligendi. Et propter hoc Aristoteles posuit quod intellectus, quo anima intelligit, non habet aliquas species naturaliter inditas, sed est in principio in potentia ad huiusmodi species omnes. Sed quia id quod habet actu formam, interdum non potest agere secundum formam propter aliquod impedimentum, sicut leve si impediatur sursum ferri; propter hoc Plato posuit quod intellectus hominis naturaliter est plenus omnibus speciebus intelligibilibus, sed per unionem corporis impeditur ne possit in actum exire. Sed hoc non videtur convenienter dictum. Primo quidem quia, si habet anima naturalem notitiam omnium, non videtur esse possibile quod huius naturalis notitiae tantam oblivionem capiat, quod nesciat se huiusmodi scientiam habere, nullus enim homo obliviscitur ea quae naturaliter cognoscit, sicut quod omne totum sit maius sua parte, et alia huiusmodi. Praecipue autem hoc videtur inconveniens, si ponatur esse animae naturale corpori uniri, ut supra habitum est, inconveniens enim est quod naturalis operatio alicuius rei totaliter impediatur per id quod est sibi secundum naturam. Secundo, manifeste apparet huius positionis falsitas ex hoc quod, deficiente aliquo sensu, deficit scientia eorum, quae apprehenduntur secundum illum sensum; sicut caecus natus nullam potest habere notitiam de coloribus. Quod non esset, si animae essent naturaliter inditae omnium intelligibilium rationes. Et ideo dicendum est quod anima non cognoscit corporalia per species naturaliter inditas. ||I answer that, Since form is the principle of action, a thing must be related to the form which is the principle of an action, as it is to that action: for instance, if upward motion is from lightness, then that which only potentially moves upwards must needs be only potentially light, but that which actually moves upwards must needs be actually light. Now we observe that man sometimes is only a potential knower, both as to sense and as to intellect. And he is reduced from such potentiality to act--through the action of sensible objects on his senses, to the act of sensation--by instruction or discovery, to the act of understanding. Wherefore we must say that the cognitive soul is in potentiality both to the images which are the principles of sensing, and to those which are the principles of understanding. For this reason Aristotle (De Anima iii, 4) held that the intellect by which the soul understands has no innate species, but is at first in potentiality to all such species. But since that which has a form actually, is sometimes unable to act according to that form on account of some hindrance, as a light thing may be hindered from moving upwards; for this reason did Plato hold that naturally man's intellect is filled with all intelligible species, but that, by being united to the body, it is hindered from the realization of its act. But this seems to be unreasonable. First, because, if the soul has a natural knowledge of all things, it seems impossible for the soul so far to forget the existence of such knowledge as not to know itself to be possessed thereof: for no man forgets what he knows naturally; that, for instance, the whole is larger than the part, and such like. And especially unreasonable does this seem if we suppose that it is natural to the soul to be united to the body, as we have established above (76 , 1): for it is unreasonable that the natural operation of a thing be totally hindered by that which belongs to it naturally. Secondly, the falseness of this opinion is clearly proved from the fact that if a sense be wanting, the knowledge of what is apprehended through that sense is wanting also: for instance, a man who is born blind can have no knowledge of colors. This would not be the case if the soul had innate images of all intelligible things. We must therefore conclude that the soul does not know corporeal things through innate species.

||<b>IЄ q. 84 a. 3 ad 1 </b>Ad primum ergo dicendum quod homo quidem convenit cum Angelis in intelligendo, deficit tamen ab eminentia intellectus eorum, sicut et corpora inferiora, quae tantum existunt secundum Gregorium, deficiunt ab existentia superiorum corporum. Nam materia inferiorum corporum non est completa totaliter per formam, sed est in potentia ad formas quas non habet, materia autem caelestium corporum est totaliter completa per formam, ita quod non est in potentia ad aliam formam, ut supra habitum est. Et similiter intellectus Angeli est perfectus per species intelligibiles secundum suam naturam, intellectus autem humanus est in potentia ad huiusmodi species. ||Reply to Objection 1. Man indeed has intelligence in common with the angels, but not in the same degree of perfection: just as the lower grades of bodies, which merely exist, according to Gregory (Homily on Ascension, xxix In Ev.), have not the same degree of perfection as the higher bodies. For the matter of the lower bodies is not totally completed by its form, but is in potentiality to forms which it has not: whereas the matter of heavenly bodies is totally completed by its form, so that it is not in potentiality to any other form, as we have said above (66, 2). In the same way the angelic intellect is perfected by intelligible species, in accordance with its nature; whereas the human intellect is in potentiality to such species.

||<b>IЄ q. 84 a. 3 ad 2 </b>Ad secundum dicendum quod materia prima habet esse substantiale per formam, et ideo oportuit quod crearetur sub aliqua forma, alioquin non esset in actu. Sub una tamen forma existens, est in potentia ad alias. Intellectus autem non habet esse substantiale per speciem intelligibilem; et ideo non est simile. ||Reply to Objection 2. Primary matter has substantial being through its form, consequently it had need to be created under some form: else it would not be in act. But when once it exists under one form it is in potentiality to others. On the other hand, the intellect does not receive substantial being through the intelligible species; and therefore there is no comparison.

||<b>IЄ q. 84 a. 3 ad 3 </b>Ad tertium dicendum quod ordinata interrogatio procedit ex principiis communibus per se notis, ad propria. Per talem autem processum scientia causatur in anima addiscentis. Unde cum verum respondet de his de quibus secundo interrogatur, hoc non est quia prius ea noverit; sed quia tunc ea de novo addiscit. Nihil enim refert utrum ille qui docet, proponendo vel interrogando procedat de principiis communibus ad conclusiones, utrobique enim animus audientis certificatur de posterioribus per priora. ||Reply to Objection 3. If questions be put in an orderly fashion they proceed from universal self-evident principles to what is particular. Now by such a process knowledge is produced in the mind of the learner. Wherefore when he answers the truth to a subsequent question, this is not because he had knowledge previously, but because he thus learns for the first time. For it matters not whether the teacher proceed from universal principles to conclusions by questioning or by asserting; for in either case the mind of the listener is assured of what follows by that which preceded.

|- valign = top
 
||<b>IЄ q. 84 a. 4 arg. 1 </b>Ad quartum sic proceditur. Videtur quod species intelligibiles effluant in animam ab aliquibus formis separatis. Omne enim quod per participationem est tale, causatur ab eo quod est per essentiam tale; sicut quod est ignitum reducitur sicut in causam in ignem. Sed anima intellectiva, secundum quod est actu intelligens, participat ipsa intelligibilia, intellectus enim in actu, quodammodo est intellectum in actu. Ergo ea quae secundum se et per essentiam suam sunt intellecta in actu, sunt causae animae intellectivae quod actu intelligat. Intellecta autem in actu per essentiam suam, sunt formae sine materia existentes. Species igitur intelligibiles quibus anima intelligit, causantur a formis aliquibus separatis. ||Objection 1. It would seem that the intelligible species are derived by the soul from some separate forms. For whatever is such by participation is caused by what is such essentially; for instance, that which is on fire is reduced to fire as the cause thereof. But the intellectual soul forasmuch as it is actually understanding, participates the thing understood: for, in a way, the intellect in act is the thing understood in act. Therefore what in itself and in its essence is understood in act, is the cause that the intellectual soul actually understands. Now that which in its essence is actually understood is a form existing without matter. Therefore the intelligible species, by which the soul understands, are caused by some separate forms.

||<b>IЄ q. 84 a. 4 arg. 2 </b>Praeterea, intelligibilia se habent ad intellectum, sicut sensibilia ad sensum. Sed sensibilia quae sunt in actu extra animam, sunt causae specierum sensibilium quae sunt in sensu, quibus sentimus. Ergo species intelligibiles quibus intellectus noster intelligit, causantur ab aliquibus actu intelligibilibus extra animam existentibus. Huiusmodi autem non sunt nisi formae a materia separatae. Formae igitur intelligibiles intellectus nostri effluunt ab aliquibus substantiis separatis. ||Objection 2. Further, the intelligible is to the intellect, as the sensible is to the sense. But the sensible species which are in the senses, and by which we sense, are caused by the sensible object which exists actually outside the soul. Therefore the intelligible species, by which our intellect understands, are caused by some things actually intelligible, existing outside the soul. But these can be nothing else than forms separate from matter. Therefore the intelligible forms of our intellect are derived from some separate substances.

||<b>IЄ q. 84 a. 4 arg. 3 </b>Praeterea, omne quod est in potentia, reducitur in actum per id quod est actu. Si ergo intellectus noster, prius in potentia existens, postmodum actu intelligat, oportet quod hoc causetur ab aliquo intellectu qui semper est in actu. Hic autem est intellectus separatus. Ergo ab aliquibus substantiis separatis causantur species intelligibiles quibus actu intelligimus. ||Objection 3. Further, whatever is in potentiality is reduced to act by something actual. If, therefore, our intellect, previously in potentiality, afterwards actually understands, this must needs be caused by some intellect which is always in act. But this is a separate intellect. Therefore the intelligible species, by which we actually understand, are caused by some separate substances.

||<b>IЄ q. 84 a. 4 co. </b>Respondeo dicendum quod quidam posuerunt species intelligibiles nostri intellectus procedere ab aliquibus formis vel substantiis separatis. Et hoc dupliciter. Plato enim, sicut dictum est, posuit formas rerum sensibilium per se sine materia subsistentes; sicut formam hominis, quam nominabat per se hominem, et formam vel ideam equi, quam nominabat per se equum, et sic de aliis. Has ergo formas separatas ponebat participari et ab anima nostra, et a materia corporali; ab anima quidem nostra ad cognoscendum, a materia vero corporali ad essendum; ut sicut materia corporalis per hoc quod participat ideam lapidis, fit hic lapis, ita intellectus noster per hoc quod participat ideam lapidis, fit intelligens lapidem. Participatio autem ideae fit per aliquam similitudinem ipsius ideae in participante ipsam, per modum quo exemplar participatur ab exemplato. Sicut igitur ponebat formas sensibiles quae sunt in materia corporali, effluere ab ideis sicut quasdam earum similitudines; ita ponebat species intelligibiles nostri intellectus esse similitudines quasdam idearum ab eis effluentes. Et propter hoc, ut supra dictum est, scientias et definitiones ad ideas referebat. Sed quia contra rationem rerum sensibilium est quod earum formae subsistant absque materiis, ut Aristoteles multipliciter probat; ideo Avicenna, hac positione remota, posuit omnium rerum sensibilium intelligibiles species, non quidem per se subsistere absque materia, sed praeexistere immaterialiter in intellectibus separatis; a quorum primo derivantur huiusmodi species in sequentem, et sic de aliis usque ad ultimum intellectum separatum, quem nominat intellectum agentem; a quo, ut ipse dicit, effluunt species intelligibiles in animas nostras, et formae sensibiles in materiam corporalem. Et sic in hoc Avicenna cum Platone concordat, quod species intelligibiles nostri intellectus effluunt a quibusdam formis separatis, quas tamen Plato dicit per se subsistere, Avicenna vero ponit eas in intelligentia agente. Differunt etiam quantum ad hoc, quod Avicenna ponit species intelligibiles non remanere in intellectu nostro postquam desinit actu intelligere; sed indiget ut iterato se convertat ad recipiendum de novo. Unde non ponit scientiam animae naturaliter inditam, sicut Plato, qui ponit participationes idearum immobiliter in anima permanere. Sed secundum hanc positionem sufficiens ratio assignari non posset quare anima nostra corpori uniretur. Non enim potest dici quod anima intellectiva corpori uniatur propter corpus, quia nec forma est propter materiam, nec motor propter mobile, sed potius e converso. Maxime autem videtur corpus esse necessarium animae intellectivae ad eius propriam operationem, quae est intelligere, quia secundum esse suum a corpore non dependet. Si autem anima species intelligibiles secundum suam naturam apta nata esset recipere per influentiam aliquorum separatorum principiorum tantum, et non acciperet eas ex sensibus, non indigeret corpore ad intelligendum, unde frustra corpori uniretur. Si autem dicatur quod indiget anima nostra sensibus ad intelligendum, quibus quodammodo excitetur ad consideranda ea quorum species intelligibiles a principiis separatis recipit; hoc non videtur sufficere. Quia huiusmodi excitatio non videtur necessaria animae nisi inquantum est consopita, secundum Platonicos, quodammodo et obliviosa propter unionem ad corpus, et sic sensus non proficerent animae intellectivae nisi ad tollendum impedimentum quod animae provenit ex corporis unione. Remanet igitur quaerendum quae sit causa unionis animae ad corpus. Si autem dicatur, secundum Avicennam, quod sensus sunt animae necessarii, quia per eos excitatur ut convertat se ad intelligentiam agentem, a qua recipit species; hoc quidem non sufficit. Quia si in natura animae est ut intelligat per species ab intelligentia agente effluxas, sequeretur quod quandoque anima possit se convertere ad intelligentiam agentem ex inclinatione suae naturae, vel etiam excitata per alium sensum, ut convertat se ad intelligentiam agentem ad recipiendum species sensibilium quorum sensum aliquis non habet. Et sic caecus natus posset habere scientiam de coloribus, quod est manifeste falsum. Unde dicendum est quod species intelligibiles quibus anima nostra intelligit, non effluunt a formis separatis. ||I answer that, Some have held that the intelligible species of our intellect are derived from certain separate forms or substances. And this in two ways. For Plato, as we have said (1), held that the forms of sensible things subsist by themselves without matter; for instance, the form of a man which he called "per se" man, and the form or idea of a horse which is called "per se" horse, and so forth. He said therefore that these forms are participated both by our soul and by corporeal matter; by our soul, to the effect of knowledge thereof, and by corporeal matter to the effect of existence: so that, just as corporeal matter by participating the idea of a stone, becomes an individuating stone, so our intellect, by participating the idea of a stone, is made to understand a stone. Now participation of an idea takes place by some image of the idea in the participator, just as a model is participated by a copy. So just as he held that the sensible forms, which are in corporeal matter, are derived from the ideas as certain images thereof: so he held that the intelligible species of our intellect are images of the ideas, derived therefrom. And for this reason, as we have said above (1), he referred sciences and definitions to those ideas. But since it is contrary to the nature of sensible things that their forms should subsist without matter, as Aristotle proves in many ways (Metaph. vi), Avicenna (De Anima v) setting this opinion aside, held that the intelligible species of all sensible things, instead of subsisting in themselves without matter, pre-exist immaterially in the separate intellects: from the first of which, said he, such species are derived by a second, and so on to the last separate intellect which he called the "active intelligence," from which, according to him, intelligible species flow into our souls, and sensible species into corporeal matter. And so Avicenna agrees with Plato in this, that the intelligible species of our intellect are derived from certain separate forms; but these Plato held to subsist of themselves, while Avicenna placed them in the "active intelligence." They differ, too, in this respect, that Avicenna held that the intelligible species do not remain in our intellect after it has ceased actually to understand, and that it needs to turn (to the active intellect) in order to receive them anew. Consequently he does not hold that the soul has innate knowledge, as Plato, who held that the participated ideas remain immovably in the soul. But in this opinion no sufficient reason can be assigned for the soul being united to the body. For it cannot be said that the intellectual soul is united to the body for the sake of the body: for neither is form for the sake of matter, nor is the mover for the sake of the moved, but rather the reverse. Especially does the body seem necessary to the intellectual soul, for the latter's proper operation which is to understand: since as to its being the soul does not depend on the body. But if the soul by its very nature had an inborn aptitude for receiving intelligible species through the influence of only certain separate principles, and were not to receive them from the senses, it would not need the body in order to understand: wherefore to no purpose would it be united to the body. But if it be said that our soul needs the senses in order to understand, through being in some way awakened by them to the consideration of those things, the intelligible species of which it receives from the separate principles: even this seems an insufficient explanation. For this awakening does not seem necessary to the soul, except in as far as it is overcome by sluggishness, as the Platonists expressed it, and by forgetfulness, through its union with the body: and thus the senses would be of no use to the intellectual soul except for the purpose of removing the obstacle which the soul encounters through its union with the body. Consequently the reason of the union of the soul with the body still remains to be sought. And if it be said with Avicenna, that the senses are necessary to the soul, because by them it is aroused to turn to the "active intelligence" from which it receives the species: neither is this a sufficient explanation. Because if it is natural for the soul to understand through species derived from the "active intelligence," it follows that at times the soul of an individual wanting in one of the senses can turn to the active intelligence, either from the inclination of its very nature, or through being roused by another sense, to the effect of receiving the intelligible species of which the corresponding sensible species are wanting. And thus a man born blind could have knowledge of colors; which is clearly untrue. We must therefore conclude that the intelligible species, by which our soul understands, are not derived from separate forms.

The intelligible species which are participated by our intellect are reduced, as to their first cause, to a first principle which is by its essence intelligible--namely, God.

Id enim in quo aliquid cognoscitur, ipsum magis et per prius cognoscitur. Sed anima intellectiva hominis, in statu praesentis vitae, non cognoscit rationes aeternas, quia non cognoscit ipsum Deum, in quo rationes aeternae existunt, sed ei sicut ignoto coniungitur, ut Dionysius dicit in I cap. mysticae theologiae. Ergo anima non cognoscit omnia in rationibus aeternis. ||Objection 1. It would seem that the intellectual soul does not know material things in the eternal types. For that in which anything is known must itself be known more and previously. But the intellectual soul of man, in the present state of life, does not know the eternal types: for it does not know God in Whom the eternal types exist, but is "united to God as to the unknown," as Dionysius says (Myst. Theolog. i). Therefore the soul does not know all in the eternal types.

Further, the eternal types are nothing else but ideas, for Augustine says (QQ. 83, qu. 46) that "ideas are permanent types existing in the Divine mind." If therefore we say that the intellectual soul knows all things in the eternal types, we come back to the opinion of Plato who said that all knowledge is derived from them.

Therefore the intellectual soul knows all true things in the eternal types.

||<b>IЄ q. 84 a. 5 co. </b>Respondeo dicendum quod, sicut Augustinus dicit in II de Doctr. Christ., philosophi qui vocantur, si qua forte vera et fidei nostrae accommoda dixerunt, ab eis tanquam ab iniustis possessoribus in usum nostrum vindicanda sunt. Habent enim doctrinae gentilium quaedam simulata et superstitiosa figmenta, quae unusquisque nostrum de societate gentilium exiens, debet evitare. Et ideo Augustinus, qui doctrinis Platonicorum imbutus fuerat, si qua invenit fidei accommoda in eorum dictis, assumpsit; quae vero invenit fidei nostrae adversa, in melius commutavit. Posuit autem Plato, sicut supra dictum est, formas rerum per se subsistere a materia separatas, quas ideas vocabat, per quarum participationem dicebat intellectum nostrum omnia cognoscere; ut sicut materia corporalis per participationem ideae lapidis fit lapis, ita intellectus noster per participationem eiusdem ideae cognosceret lapidem. Sed quia videtur esse alienum a fide quod formae rerum extra res per se subsistant absque materia, sicut Platonici posuerunt, dicentes per se vitam aut per se sapientiam esse quasdam substantias creatrices, ut Dionysius dicit XI cap. de Div. Nom.; ideo Augustinus, in libro octoginta trium quaest., posuit loco harum idearum quas Plato ponebat, rationes omnium creaturarum in mente divina existere, secundum quas omnia formantur, et secundum quas etiam anima humana omnia cognoscit. Cum ergo quaeritur utrum anima humana in rationibus aeternis omnia cognoscat, dicendum est quod aliquid in aliquo dicitur cognosci dupliciter. Uno modo, sicut in obiecto cognito; sicut aliquis videt in speculo ea quorum imagines in speculo resultant. Et hoc modo anima, in statu praesentis vitae, non potest videre omnia in rationibus aeternis; sed sic in rationibus aeternis cognoscunt omnia beati, qui Deum vident et omnia in ipso. Alio modo dicitur aliquid cognosci in aliquo sicut in cognitionis principio; sicut si dicamus quod in sole videntur ea quae videntur per solem. Et sic necesse est dicere quod anima humana omnia cognoscat in rationibus aeternis, per quarum participationem omnia cognoscimus. Ipsum enim lumen intellectuale quod est in nobis, nihil est aliud quam quaedam participata similitudo luminis increati, in quo continentur rationes aeternae. Unde in Psalmo IV, dicitur, multi dicunt, quis ostendit nobis bona? Cui quaestioni Psalmista respondet, dicens, signatum est super nos lumen vultus tui, domine. Quasi dicat, per ipsam sigillationem divini luminis in nobis, omnia nobis demonstrantur. Quia tamen praeter lumen intellectuale in nobis, exiguntur species intelligibiles a rebus acceptae, ad scientiam de rebus materialibus habendam; ideo non per solam participationem rationum aeternarum de rebus materialibus notitiam habemus, sicut Platonici posuerunt quod sola idearum participatio sufficit ad scientiam habendam. Unde Augustinus dicit, in IV de Trin., numquid quia philosophi documentis certissimis persuadent aeternis rationibus omnia temporalia fieri, propterea potuerunt in ipsis rationibus perspicere, vel ex ipsis colligere quot sint animalium genera, quae semina singulorum? Nonne ista omnia per locorum ac temporum historiam quaesierunt? Quod autem Augustinus non sic intellexerit omnia cognosci in rationibus aeternis, vel in incommutabili veritate, quasi ipsae rationes aeternae videantur, patet per hoc quod ipse dicit in libro octoginta trium quaest., quod rationalis anima non omnis et quaelibet, sed quae sancta et pura fuerit, asseritur illi visioni, scilicet rationum aeternarum, esse idonea; sicut sunt animae beatorum. ||I answer that, As Augustine says (De Doctr. Christ. ii, 11): "If those who are called philosophers said by chance anything that was true and consistent with our faith, we must claim it from them as from unjust possessors. For some of the doctrines of the heathens are spurious imitations or superstitious inventions, which we must be careful to avoid when we renounce the society of the heathens." Consequently whenever Augustine, who was imbued with the doctrines of the Platonists, found in their teaching anything consistent with faith, he adopted it: and those thing which he found contrary to faith he amended. Now Plato held, as we have said above (4), that the forms of things subsist of themselves apart from matter; and these he called ideas, by participation of which he said that our intellect knows all things: so that just as corporeal matter by participating the idea of a stone becomes a stone, so our intellect, by participating the same idea, has knowledge of a stone. But since it seems contrary to faith that forms of things themselves, outside the things themselves and apart from matter, as the Platonists held, asserting that "per se" life or "per se" wisdom are creative substances, as Dionysius relates (Div. Nom. xi); therefore Augustine (QQ. 83, qu. 46), for the ideas defended by Plato, substituted the types of all creatures existing in the Divine mind, according to which types all things are made in themselves, and are known to the human soul. When, therefore, the question is asked: Does the human soul know all things in the eternal types? we must reply that one thing is said to be known in another in two ways. First, as in an object itself known; as one may see in a mirror the images of things reflected therein. In this way the soul, in the present state of life, cannot see all things in the eternal types; but the blessed who see God, and all things in Him, thus know all things in the eternal types. Secondly, on thing is said to be known in another as in a principle of knowledge: thus we might say that we see in the sun what we see by the sun. And thus we must needs say that the human soul knows all things in the eternal types, since by participation of these types we know all things. For the intellectual light itself which is in us, is nothing else than a participated likeness of the uncreated light, in which are contained the eternal types. Whence it is written (Ps. 4:6,7), "Many say: Who showeth us good things?" which question the Psalmist answers, "The light of Thy countenance, O Lord, is signed upon us," as though he were to say: By the seal of the Divine light in us, all things are made known to us. But since besides the intellectual light which is in us, intelligible species, which are derived from things, are required in order for us to have knowledge of material things; therefore this same knowledge is not due merely to a participation of the eternal types, as the Platonists held, maintaining that the mere participation of ideas sufficed for knowledge. Wherefore Augustine says (De Trin. iv, 16): "Although the philosophers prove by convincing arguments that all things occur in time according to the eternal types, were they able to see in the eternal types, or to find out from them how many kinds of animals there are and the origin of each? Did they not seek for this information from the story of times and places?" But that Augustine did not understand all things to be known in their "eternal types" or in the "unchangeable truth," as though the eternal types themselves were seen, is clear from what he says (QQ. 83, qu. 46)--viz. that "not each and every rational soul can be said to be worthy of that vision," namely, of the eternal types, "but only those that are holy and pure," such as the souls of the blessed.

||<b>IЄ q. 84 a. 6 arg. 1 </b>Ad sextum sic proceditur. Videtur quod intellectiva cognitio non accipiatur a rebus sensibilibus. Dicit enim Augustinus, in libro octoginta trium quaest., quod non est expectanda sinceritas veritatis a corporis sensibus. Et hoc probat dupliciter. Uno modo, per hoc quod omne quod corporeus sensus attingit, sine ulla intermissione temporis commutatur, quod autem non manet, percipi non potest. Alio modo, per hoc quod omnia quae per corpus sentimus, etiam cum non adsunt sensibus, imagines tamen eorum patimur, ut in somno vel furore; non autem sensibus discernere valemus utrum ipsa sensibilia, vel imagines eorum falsas sentiamus. Nihil autem percipi potest quod a falso non discernitur. Et sic concludit quod non est expectanda veritas a sensibus. Sed cognitio intellectualis est apprehensiva veritatis. Non ergo cognitio intellectualis est expectanda a sensibus. ||Objection 1. It would seem that intellectual knowledge is not derived from sensible things. For Augustine says (QQ. 83, qu. 9) that "we cannot expect to learn the fulness of truth from the senses of the body." This he proves in two ways. First, because "whatever the bodily senses reach, is continually being changed; and what is never the same cannot be perceived."  Secondly, because, "whatever we perceive by the body, even when not present to the senses, may be present to the imagination, as when we are asleep or angry: yet we cannot discern by the senses, whether what we perceive be the sensible object or the deceptive image thereof. Now nothing can be perceived which cannot be distinguished from its counterfeit." And so he concludes that we cannot expect to learn the truth from the senses. But intellectual knowledge apprehends the truth. Therefore intellectual knowledge cannot be conveyed by the senses.

||<b>IЄ q. 84 a. 6 arg. 2 </b>Praeterea, Augustinus dicit, XII super Gen. ad Litt., non est putandum facere aliquid corpus in spiritum, tanquam spiritus corpori facienti materiae vice subdatur, omni enim modo praestantior est qui facit, ea re de qua aliquid facit. Unde concludit quod imaginem corporis non corpus in spiritu, sed ipse spiritus in seipso facit. Non ergo intellectualis cognitio a sensibilibus derivatur. ||Objection 2. Further, Augustine says (Gen. ad lit. xii, 16): "We must not think that the body can make any impression on the spirit, as though the spirit were to supply the place of matter in regard to the body's action; for that which acts is in every way more excellent than that which it acts on." Whence he concludes that "the body does not cause its image in the spirit, but the spirit causes it in itself." Therefore intellectual knowledge is not derived from sensible things.

||<b>IЄ q. 84 a. 6 co. </b>Respondeo dicendum quod circa istam quaestionem triplex fuit philosophorum opinio. Democritus enim posuit quod nulla est alia causa cuiuslibet nostrae cognitionis, nisi cum ab his corporibus quae cogitamus, veniunt atque intrant imagines in animas nostras; ut Augustinus dicit in epistola sua ad Dioscorum. Et Aristoteles etiam dicit, in libro de Somn. et Vigil., quod Democritus posuit cognitionem fieri per idola et defluxiones. Et huius positionis ratio fuit, quia tam ipse Democritus quam alii antiqui naturales non ponebant intellectum differre a sensu, ut Aristoteles dicit in libro de anima. Et ideo, quia sensus immutatur a sensibili, arbitrabantur omnem nostram cognitionem fieri per solam immutationem a sensibilibus. Quam quidem immutationem Democritus asserebat fieri per imaginum defluxiones. Plato vero e contrario posuit intellectum differre a sensu; et intellectum quidem esse virtutem immaterialem organo corporeo non utentem in suo actu. Et quia incorporeum non potest immutari a corporeo, posuit quod cognitio intellectualis non fit per immutationem intellectus a sensibilibus, sed per participationem formarum intelligibilium separatarum, ut dictum est. Sensum etiam posuit virtutem quandam per se operantem. Unde nec ipse sensus, cum sit quaedam vis spiritualis, immutatur a sensibilibus, sed organa sensuum a sensibilibus immutantur, ex qua immutatione anima quodammodo excitatur ut in se species sensibilium formet. Et hanc opinionem tangere videtur Augustinus, XII super Gen. ad Litt., ubi dicit quod corpus non sentit, sed anima per corpus, quo velut nuntio utitur ad formandum in seipsa quod extrinsecus nuntiatur. Sic igitur secundum Platonis opinionem, neque intellectualis cognitio a sensibili procedit, neque etiam sensibilis totaliter a sensibilibus rebus; sed sensibilia excitant animam sensibilem ad sentiendum, et similiter sensus excitant animam intellectivam ad intelligendum. Aristoteles autem media via processit. Posuit enim cum Platone intellectum differre a sensu. Sed sensum posuit propriam operationem non habere sine communicatione corporis; ita quod sentire non sit actus animae tantum, sed coniuncti. Et similiter posuit de omnibus operationibus sensitivae partis. Quia igitur non est inconveniens quod sensibilia quae sunt extra animam, causent aliquid in coniunctum, in hoc Aristoteles cum Democrito concordavit, quod operationes sensitivae partis causentur per impressionem sensibilium in sensum, non per modum defluxionis, ut Democritus posuit, sed per quandam operationem. Nam et Democritus omnem actionem fieri posuit per influxionem atomorum, ut patet in I de Generat. Intellectum vero posuit Aristoteles habere operationem absque communicatione corporis. Nihil autem corporeum imprimere potest in rem incorpoream. Et ideo ad causandam intellectualem operationem, secundum Aristotelem, non sufficit sola impressio sensibilium corporum, sed requiritur aliquid nobilius, quia agens est honorabilius patiente, ut ipse dicit. Non tamen ita quod intellectualis operatio causetur in nobis ex sola impressione aliquarum rerum superiorum, ut Plato posuit, sed illud superius et nobilius agens quod vocat intellectum agentem, de quo iam supra diximus, facit phantasmata a sensibus accepta intelligibilia in actu, per modum abstractionis cuiusdam. Secundum hoc ergo, ex parte phantasmatum intellectualis operatio a sensu causatur. Sed quia phantasmata non sufficiunt immutare intellectum possibilem, sed oportet quod fiant intelligibilia actu per intellectum agentem; non potest dici quod sensibilis cognitio sit totalis et perfecta causa intellectualis cognitionis, sed magis quodammodo est materia causae. ||I answer that, On this point the philosophers held three opinions. For Democritus held that "all knowledge is caused by images issuing from the bodies we think of and entering into our souls," as Augustine says in his letter to Dioscorus (cxviii, 4). And Aristotle says (De Somn. et Vigil.) that Democritus held that knowledge is cause by a "discharge of images." And the reason for this opinion was that both Democritus and the other early philosophers did not distinguish between intellect and sense, as Aristotle relates (De Anima iii, 3). Consequently, since the sense is affected by the sensible, they thought that all our knowledge is affected by this mere impression brought about by sensible things. Which impression Democritus held to be caused by a discharge of images. Plato, on the other hand, held that the intellect is distinct from the senses: and that it is an immaterial power not making use of a corporeal organ for its action. And since the incorporeal cannot be affected by the corporeal, he held that intellectual knowledge is not brought about by sensible things affecting the intellect, but by separate intelligible forms being participated by the intellect, as we have said above (4 ,5). Moreover he held that sense is a power operating of itself. Consequently neither is sense, since it is a spiritual power, affected by the sensible: but the sensible organs are affected by the sensible, the result being that the soul is in a way roused to form within itself the species of the sensible. Augustine seems to touch on this opinion (Gen. ad lit. xii, 24) where he says that the "body feels not, but the soul through the body, which it makes use of as a kind of messenger, for reproducing within itself what is announced from without." Thus according to Plato, neither does intellectual knowledge proceed from sensible knowledge, nor sensible knowledge exclusively from sensible things; but these rouse the sensible soul to the sentient act, while the senses rouse the intellect to the act of understanding. Aristotle chose a middle course. For with Plato he agreed that intellect and sense are different. But he held that the sense has not its proper operation without the cooperation of the body; so that to feel is not an act of the soul alone, but of the "composite." And he held the same in regard to all the operations of the sensitive part. Since, therefore, it is not unreasonable that the sensible objects which are outside the soul should produce some effect in the "composite," Aristotle agreed with Democritus in this, that the operations of the sensitive part are caused by the impression of the sensible on the sense: not by a discharge, as Democritus said, but by some kind of operation. For Democritus maintained that every operation is by way of a discharge of atoms, as we gather from De Gener. i, 8. But Aristotle held that the intellect has an operation which is independent of the body's cooperation. Now nothing corporeal can make an impression on the incorporeal. And therefore in order to cause the intellectual operation according to Aristotle, the impression caused by the sensible does not suffice, but something more noble is required, for "the agent is more noble than the patient," as he says (De Gener. i, 5). Not, indeed, in the sense that the intellectual operation is effected in us by the mere intellectual operation is effected in us by the mere impression of some superior beings, as Plato held; but that the higher and more noble agent which he calls the active intellect, of which we have spoken above (79, 3,4) causes the phantasms received from the senses to be actually intelligible, by a process of abstraction. According to this opinion, then, on the part of the phantasms, intellectual knowledge is caused by the senses. But since the phantasms cannot of themselves affect the passive intellect, and require to be made actually intelligible by the active intellect, it cannot be said that sensible knowledge is the total and perfect cause of intellectual knowledge, but rather that it is in a way the material cause.

For the light of the active intellect is needed, through which we achieve the unchangeable truth of changeable things, and discern things themselves from their likeness.

||<b>IЄ q. 84 a. 6 ad 2 </b>Ad secundum dicendum quod Augustinus ibi non loquitur de intellectuali cognitione, sed de imaginaria. Et quia, secundum Platonis opinionem, vis imaginaria habet operationem quae est animae solius; eadem ratione usus est Augustinus ad ostendendum quod corpora non imprimunt suas similitudines in vim imaginariam, sed hoc facit ipsa anima, qua utitur Aristoteles ad probandum intellectum agentem esse aliquid separatum, quia scilicet agens est honorabilius patiente. Et procul dubio oportet, secundum hanc positionem, in vi imaginativa ponere non solum potentiam passivam, sed etiam activam. Sed si ponamus, secundum opinionem Aristotelis, quod actio virtutis imaginativae sit coniuncti, nulla sequitur difficultas, quia corpus sensibile est nobilius organo animalis, secundum hoc quod comparatur ad ipsum ut ens in actu ad ens in potentia, sicut coloratum in actu ad pupillam, quae colorata est in potentia. Posset tamen dici quod, quamvis prima immutatio virtutis imaginariae sit per motum sensibilium, quia phantasia est motus factus secundum sensum, ut dicitur in libro de anima; tamen est quaedam operatio animae in homine quae dividendo et componendo format diversas rerum imagines, etiam quae non sunt a sensibus acceptae. Et quantum ad hoc possunt accipi verba Augustini. ||Reply to Objection 2. In this passage Augustine speaks not of intellectual but of imaginary knowledge. And since, according to the opinion of Plato, the imagination has an operation which belongs to the soul only, Augustine, in order to show that corporeal images are impressed on the imagination, not by bodies but by the soul, uses the same argument as Aristotle does in proving that the active intellect must be separate, namely, because "the agent is more noble than the patient." And without doubt, according to the above opinion, in the imagination there must needs be not only a passive but also an active power. But if we hold, according to the opinion of Aristotle, that the action of the imagination, is an action of the "composite," there is no difficulty; because the sensible body is more noble than the organ of the animal, in so far as it is compared to it as a being in act to a being in potentiality; even as the object actually colored is compared to the pupil which is potentially colored. It may, however, be said, although the first impression of the imagination is through the agency of the sensible, since "fancy is movement produced in accordance with sensation" (De Anima iii, 3), that nevertheless there is in man an operation which by synthesis and analysis forms images of various things, even of things not perceived by the senses. And Augustine's words may be taken in this sense.

Ergo species intelligibiles sufficiunt ad hoc quod intellectus actu intelligat, absque hoc quod ad phantasmata se convertat. ||Objection 1. It would seem that the intellect can actually understand through the intelligible species of which it is possessed, without turning to the phantasms. For the intellect is made actual by the intelligible species by which it is informed. But if the intellect is in act, it understands. Therefore the intelligible species suffices for the intellect to understand actually, without turning to the phantasms.

||<b>IЄ q. 84 a. 7 arg. 2 </b>Praeterea, magis dependet imaginatio a sensu, quam intellectus ab imaginatione. Sed imaginatio potest imaginari actu, absentibus sensibilibus.

But the imagination can actually imagine in the absence of the sensible. Therefore much more can the intellect understand without turning to the phantasms.

|- valign = top
 
||<b>IЄ q. 84 a. 7 co. </b>Respondeo dicendum quod impossibile est intellectum nostrum, secundum praesentis vitae statum, quo passibili corpori coniungitur, aliquid intelligere in actu, nisi convertendo se ad phantasmata. Et hoc duobus indiciis apparet. Primo quidem quia, cum intellectus sit vis quaedam non utens corporali organo, nullo modo impediretur in suo actu per laesionem alicuius corporalis organi, si non requireretur ad eius actum actus alicuius potentiae utentis organo corporali. Utuntur autem organo corporali sensus et imaginatio et aliae vires pertinentes ad partem sensitivam. Unde manifestum est quod ad hoc quod intellectus actu intelligat, non solum accipiendo scientiam de novo, sed etiam utendo scientia iam acquisita, requiritur actus imaginationis et ceterarum virtutum. Videmus enim quod, impedito actu virtutis imaginativae per laesionem organi, ut in phreneticis; et similiter impedito actu memorativae virtutis, ut in lethargicis; impeditur homo ab intelligendo in actu etiam ea quorum scientiam praeaccepit. Secundo, quia hoc quilibet in seipso experiri potest, quod quando aliquis conatur aliquid intelligere, format aliqua phantasmata sibi per modum exemplorum, in quibus quasi inspiciat quod intelligere studet. Et inde est etiam quod quando alium volumus facere aliquid intelligere, proponimus ei exempla, ex quibus sibi phantasmata formare possit ad intelligendum. Huius autem ratio est, quia potentia cognoscitiva proportionatur cognoscibili. Unde intellectus angelici, qui est totaliter a corpore separatus, obiectum proprium est substantia intelligibilis a corpore separata; et per huiusmodi intelligibilia materialia cognoscit. Intellectus autem humani, qui est coniunctus corpori, proprium obiectum est quidditas sive natura in materia corporali existens; et per huiusmodi naturas visibilium rerum etiam in invisibilium rerum aliqualem cognitionem ascendit. De ratione autem huius naturae est, quod in aliquo individuo existat, quod non est absque materia corporali, sicut de ratione naturae lapidis est quod sit in hoc lapide, et de ratione naturae equi quod sit in hoc equo, et sic de aliis. Unde natura lapidis, vel cuiuscumque materialis rei, cognosci non potest complete et vere, nisi secundum quod cognoscitur ut in particulari existens. Particulare autem apprehendimus per sensum et imaginationem. Et ideo necesse est ad hoc quod intellectus actu intelligat suum obiectum proprium, quod convertat se ad phantasmata, ut speculetur naturam universalem in particulari existentem. Si autem proprium obiectum intellectus nostri esset forma separata; vel si naturae rerum sensibilium subsisterent non in particularibus, secundum Platonicos; non oporteret quod intellectus noster semper intelligendo converteret se ad phantasmata. ||I answer that, In the present state of life in which the soul is united to a passible body, it is impossible for our intellect to understand anything actually, except by turning to the phantasms. First of all because the intellect, being a power that does not make use of a corporeal organ, would in no way be hindered in its act through the lesion of a corporeal organ, if for its act there were not required the act of some power that does make use of a corporeal organ. Now sense, imagination and the other powers belonging to the sensitive part, make use of a corporeal organ. Wherefore it is clear that for the intellect to understand actually, not only when it acquires fresh knowledge, but also when it applies knowledge already acquired, there is need for the act of the imagination and of the other powers. For when the act of the imagination is hindered by a lesion of the corporeal organ, for instance in a case of frenzy; or when the act of the memory is hindered, as in the case of lethargy, we see that a man is hindered from actually understanding things of which he had a previous knowledge. Secondly, anyone can experience this of himself, that when he tries to understand something, he forms certain phantasms to serve him by way of examples, in which as it were he examines what he is desirous of understanding. For this reason it is that when we wish to help someone to understand something, we lay examples before him, from which he forms phantasms for the purpose of understanding. Now the reason of this is that the power of knowledge is proportioned to the thing known. Wherefore the proper object of the angelic intellect, which is entirely separate from a body, is an intelligible substance separate from a body. Whereas the proper object of the human intellect, which is united to a body, is a quiddity or nature existing in corporeal matter; and through such natures of visible things it rises to a certain knowledge of things invisible. Now it belongs to such a nature to exist in an individual, and this cannot be apart from corporeal matter: for instance, it belongs to the nature of a stone to be in an individual stone, and to the nature of a horse to be in an individual horse, and so forth. Wherefore the nature of a stone or any material thing cannot be known completely and truly, except in as much as it is known as existing in the individual. Now we apprehend the individual through the senses and the imagination. And, therefore, for the intellect to understand actually its proper object, it must of necessity turn to the phantasms in order to perceive the universal nature existing in the individual. But if the proper object of our intellect were a separate form; or if, as the Platonists say, the natures of sensible things subsisted apart from the individual; there would be no need for the intellect to turn to the phantasms whenever it understands.

The species preserved in the passive intellect exist there habitually when it does not understand them actually, as we have said above (79, 6).

Incorporeal things, of which there are no phantasms, are known to us by comparison with sensible bodies of which there are phantasms. Thus we understand truth by considering a thing of which we possess the truth; and God, as Dionysius says (Div. Nom. i), we know as cause, by way of excess and by way of remotion. Other incorporeal substances we know, in the present state of life, only by way of remotion or by some comparison to corporeal things. And, therefore, when we understand something about these things, we need to turn to phantasms of bodies, although there are no phantasms of the things themselves.

Iudicium autem perfectum de re aliqua dari non potest, nisi ea omnia quae ad rem pertinent cognoscantur, et praecipue si ignoretur id quod est terminus et finis iudicii. Dicit autem philosophus, in III de caelo, quod sicut finis factivae scientiae est opus, ita naturalis scientiae finis est quod videtur principaliter secundum sensum, faber enim non quaerit cognitionem cultelli nisi propter opus, ut operetur hunc particularem cultellum; et similiter naturalis non quaerit cognoscere naturam lapidis et equi, nisi ut sciat rationes eorum quae videntur secundum sensum. Manifestum est autem quod non posset esse perfectum iudicium fabri de cultello, si opus ignoraret, et similiter non potest esse perfectum iudicium scientiae naturalis de rebus naturalibus, si sensibilia ignorentur. Omnia autem quae in praesenti statu intelligimus, cognoscuntur a nobis per comparationem ad res sensibiles naturales. Unde impossibile est quod sit in nobis iudicium intellectus perfectum, cum ligamento sensus, per quem res sensibiles cognoscimus. ||I answer that, As we have said above (7), our intellect's proper and proportionate object is the nature of a sensible thing. Now a perfect judgment concerning anything cannot be formed, unless all that pertains to that thing's nature be known; especially if that be ignored which is the term and end of judgment. Now the Philosopher says (De Coel. iii), that "as the end of a practical science is action, so the end of natural science is that which is perceived principally through the senses"; for the smith does not seek knowledge of a knife except for the purpose of action, in order that he may produce a certain individual knife; and in like manner the natural philosopher does not seek to know the nature of a stone and of a horse, save for the purpose of knowing the essential properties of those things which he perceives with his senses. Now it is clear that a smith cannot judge perfectly of a knife unless he knows the action of the knife: and in like manner the natural philosopher cannot judge perfectly of natural things, unless he knows sensible things. But in the present state of life whatever we understand, we know by comparison to natural sensible things. Consequently it is not possible for our intellect to form a perfect judgment, while the senses are suspended, through which sensible things are known to us.

||<b>IЄ q. 84 a. 8 ad 2 </b>Ad secundum dicendum quod sensus ligatur in dormientibus propter evaporationes quasdam et fumositates resolutas, ut dicitur in libro de Somn. et Vig. Et ideo secundum dispositionem huiusmodi evaporationum, contingit esse ligamentum sensus maius vel minus. Quando enim multus fuerit motus vaporum, ligatur non solum sensus, sed etiam imaginatio, ita ut nulla appareant phantasmata; sicut praecipue accidit cum aliquis incipit dormire post multum cibum et potum. Si vero motus vaporum aliquantulum fuerit remissior, apparent phantasmata, sed distorta et inordinata; sicut accidit in febricitantibus. Si vero adhuc magis motus sedetur, apparent phantasmata ordinata; sicut maxime solet contingere in fine dormitionis, et in hominibus sobriis et habentibus fortem imaginationem. Si autem motus vaporum fuerit modicus, non solum imaginatio remanet libera, sed etiam ipse sensus communis ex parte solvitur; ita quod homo iudicat interdum in dormiendo ea quae videt somnia esse, quasi diiudicans inter res et rerum similitudines. Sed tamen ex aliqua parte remanet sensus communis ligatus; et ideo, licet aliquas similitudines discernat a rebus, tamen semper in aliquibus decipitur. Sic igitur per modum quo sensus solvitur et imaginatio in dormiendo, liberatur et iudicium intellectus, non tamen ex toto. Unde illi qui dormiendo syllogizant, cum excitantur, semper recognoscunt se in aliquo defecisse. ||Reply to Objection 2. The senses are suspended in the sleeper through certain evaporations and the escape of certain exhalations, as we read in De Somn. et Vigil. iii. And, therefore, according to the amount of such evaporation, the senses are more or less suspended. For when the amount is considerable, not only are the senses suspended, but also the imagination, so that there are no phantasms; thus does it happen, especially when a man falls asleep after eating and drinking copiously. If, however, the evaporation be somewhat less, phantasms appear, but distorted and without sequence; thus it happens in a case of fever. And if the evaporation be still more attenuated, the phantasms will have a certain sequence: thus especially does it happen towards the end of sleep in sober men and those who are gifted with a strong imagination. If the evaporation be very slight, not only does the imagination retain its freedom, but also the common sense is partly freed; so that sometimes while asleep a man may judge that what he sees is a dream, discerning, as it were, between things, and their images. Nevertheless, the common sense remains partly suspended; and therefore, although it discriminates some images from the reality, yet is it always deceived in some particular. Therefore, while man is asleep, according as sense and imagination are free, so is the judgment of his intellect unfettered, though not entirely. Consequently, if a man syllogizes while asleep, when he wakes up he invariably recognizes a flaw in some respect.

||<b>IЄ q. 85 a. 1 arg. 1 </b>Ad primum sic proceditur. Videtur quod intellectus noster non intelligat res corporeas et materiales per abstractionem a phantasmatibus. Quicumque enim intellectus intelligit rem aliter quam sit, est falsus. Formae autem rerum materialium non sunt abstractae a particularibus, quorum similitudines sunt phantasmata. Si ergo intelligamus res materiales per abstractionem specierum a phantasmatibus, erit falsitas in intellectu nostro. ||Objection 1. It would seem that our intellect does not understand corporeal and material things by abstraction from the phantasms. For the intellect is false if it understands an object otherwise than as it really is. Now the forms of material things do not exist as abstracted from the particular things represented by the phantasms. Therefore, if we understand material things by abstraction of the species from the phantasm, there will be error in the intellect.

||<b>IЄ q. 85 a. 1 arg. 2 </b>Praeterea, res materiales sunt res naturales, in quarum definitione cadit materia. Sed nihil potest intelligi sine eo quod cadit in definitione eius.

Further, material things are those natural things which include matter in their definition. But nothing can be understood apart from that which enters into its definition. Therefore material things cannot be understood apart from matter. Now matter is the principle of individualization. Therefore material things cannot be understood by abstraction of the universal from the particular, which is the process whereby the intelligible species is abstracted from the phantasm

||<b>IЄ q. 85 a. 1 arg. 3 </b>Praeterea, in III de anima dicitur quod phantasmata se habent ad animam intellectivam sicut colores ad visum.

Ergo nec intelligere contingit per hoc quod aliquid abstrahatur a phantasmatibus, sed per hoc quod phantasmata imprimunt in intellectum. ||Objection 3. Further, the Philosopher says (De Anima iii, 7) that the phantasm is to the intellectual soul what color is to the sight. But seeing is not caused by abstraction of species from color, but by color impressing itself on the sight. Therefore neither does the act of understanding take place by abstraction of something from the phantasm, but by the phantasm impressing itself on the intellect.

Sed nec etiam videtur pertinere ad intellectum agentem, qui se habet ad phantasmata sicut lumen ad colores, quod non abstrahit aliquid a coloribus, sed magis eis influit. Ergo nullo modo intelligimus abstrahendo a phantasmatibus. ||Objection 4. Further, the Philosopher says (De Anima iii, 5) there are two things in the intellectual soul--the passive intellect and the active intellect. But it does not belong to the passive intellect to abstract the intelligible species from the phantasm, but to receive them when abstracted. Neither does it seem to be the function of the active intellect, which is related to the phantasm, as light is to color; since light does not abstract anything from color, but rather streams on to it. Therefore in no way do we understand by abstraction from phantasms.

||<b>IЄ q. 85 a. 1 co. 1 </b>Respondeo dicendum quod, sicut supra dictum est, obiectum cognoscibile proportionatur virtuti cognoscitivae. Est autem triplex gradus cognoscitivae virtutis. Quaedam enim cognoscitiva virtus est actus organi corporalis, scilicet sensus. Et ideo obiectum cuiuslibet sensitivae potentiae est forma prout in materia corporali existit. Et quia huiusmodi materia est individuationis principium, ideo omnis potentia sensitivae partis est cognoscitiva particularium tantum. Quaedam autem virtus cognoscitiva est quae neque est actus organi corporalis, neque est aliquo modo corporali materiae coniuncta, sicut intellectus angelicus. Et ideo huius virtutis cognoscitivae obiectum est forma sine materia subsistens, etsi enim materialia cognoscant, non tamen nisi in immaterialibus ea intuentur, scilicet vel in seipsis vel in Deo. ||I answer that, As stated above (84, 7), the object of knowledge is proportionate to the power of knowledge. Now there are three grades of the cognitive powers. For one cognitive power, namely, the sense, is the act of a corporeal organ. And therefore the object of every sensitive power is a form as existing in corporeal matter. And since such matter is the principle of individuality, therefore every power of the sensitive part can only have knowledge of the individual. There is another grade of cognitive power which is neither the act of a corporeal organ, nor in any way connected with corporeal matter; such is the angelic intellect, the object of whose cognitive power is therefore a form existing apart from matter: for though angels know material things, yet they do not know them save in something immaterial, namely, either in themselves or in God.

||<b>IЄ q. 85 a. 1 co. 2 </b>Intellectus autem humanus medio modo se habet, non enim est actus alicuius organi, sed tamen est quaedam virtus animae, quae est forma corporis, ut ex supra dictis patet. Et ideo proprium eius est cognoscere formam in materia quidem corporali individualiter existentem, non tamen prout est in tali materia. Cognoscere vero id quod est in materia individuali, non prout est in tali materia, est abstrahere formam a materia individuali, quam repraesentant phantasmata. Et ideo necesse est dicere quod intellectus noster intelligit materialia abstrahendo a phantasmatibus; et per materialia sic considerata in immaterialium aliqualem cognitionem devenimus, sicut e contra Angeli per immaterialia materialia cognoscunt. Plato vero, attendens solum ad immaterialitatem intellectus humani, non autem ad hoc quod est corpori quodammodo unitus, posuit obiectum intellectus ideas separatas; et quod intelligimus, non quidem abstrahendo, sed magis abstracta participando, ut supra dictum est. ||But the human intellect holds a middle place: for it is not the act of an organ; yet it is a power of the soul which is the form the body, as is clear from what we have said above (76, 1). And therefore it is proper to it to know a form existing individually in corporeal matter, but not as existing in this individual matter. But to know what is in individual matter, not as existing in such matter, is to abstract the form from individual matter which is represented by the phantasms. Therefore we must needs say that our intellect understands material things by abstracting from the phantasms; and through material things thus considered we acquire some knowledge of immaterial things, just as, on the contrary, angels know material things through the immaterial. But Plato, considering only the immateriality of the human intellect, and not its being in a way united to the body, held that the objects of the intellect are separate ideas; and that we understand not by abstraction, but by participating things abstract, as stated above (84 , 1).

||<b>IЄ q. 85 a. 1 ad 1 </b>Ad primum ergo dicendum quod abstrahere contingit dupliciter. Uno modo, per modum compositionis et divisionis; sicut cum intelligimus aliquid non esse in alio, vel esse separatum ab eo. Alio modo, per modum simplicis et absolutae considerationis; sicut cum intelligimus unum, nihil considerando de alio. Abstrahere igitur per intellectum ea quae secundum rem non sunt abstracta, secundum primum modum abstrahendi, non est absque falsitate. Sed secundo modo abstrahere per intellectum quae non sunt abstracta secundum rem, non habet falsitatem; ut in sensibilibus manifeste apparet. Si enim intelligamus vel dicamus colorem non inesse corpori colorato, vel esse separatum ab eo, erit falsitas in opinione vel in oratione. Si vero consideremus colorem et proprietates eius, nihil considerantes de pomo colorato; vel quod sic intelligimus, etiam voce exprimamus; erit absque falsitate opinionis et orationis. Pomum enim non est de ratione coloris; et ideo nihil prohibet colorem intelligi, nihil intelligendo de pomo. Similiter dico quod ea quae pertinent ad rationem speciei cuiuslibet rei materialis, puta lapidis aut hominis aut equi, possunt considerari sine principiis individualibus, quae non sunt de ratione speciei. Et hoc est abstrahere universale a particulari, vel speciem intelligibilem a phantasmatibus, considerare scilicet naturam speciei absque consideratione individualium principiorum, quae per phantasmata repraesentantur. Cum ergo dicitur quod intellectus est falsus qui intelligit rem aliter quam sit, verum est si ly aliter referatur ad rem intellectam. Tunc enim intellectus est falsus, quando intelligit rem esse aliter quam sit. Unde falsus esset intellectus, si sic abstraheret speciem lapidis a materia, ut intelligeret eam non esse in materia, ut Plato posuit. Non est autem verum quod proponitur, si ly aliter accipiatur ex parte intelligentis. Est enim absque falsitate ut alius sit modus intelligentis in intelligendo, quam modus rei in existendo, quia intellectum est in intelligente immaterialiter, per modum intellectus; non autem materialiter, per modum rei materialis. ||Reply to Objection 1. Abstraction may occur in two ways: First, by way of composition and division; thus we may understand that one thing does not exist in some other, or that it is separate therefrom.  Secondly, by way of simple and absolute consideration; thus we understand one thing without considering the other. Thus for the intellect to abstract one from another things which are not really abstract from one another, does, in the first mode of abstraction, imply falsehood. But, in the second mode of abstraction, for the intellect to abstract things which are not really abstract from one another, does not involve falsehood, as clearly appears in the case of the senses. For if we understood or said that color is not in a colored body, or that it is separate from it, there would be error in this opinion or assertion. But if we consider color and its properties, without reference to the apple which is colored; or if we express in word what we thus understand, there is no error in such an opinion or assertion, because an apple is not essential to color, and therefore color can be understood independently of the apple. Likewise, the things which belong to the species of a material thing, such as a stone, or a man, or a horse, can be thought of apart from the individualizing principles which do not belong to the notion of the species. This is what we mean by abstracting the universal from the particular, or the intelligible species from the phantasm; that is, by considering the nature of the species apart from its individual qualities represented by the phantasms. If, therefore, the intellect is said to be false when it understands a thing otherwise than as it is, that is so, if the word "otherwise" refers to the thing understood; for the intellect is false when it understands a thing otherwise than as it is; and so the intellect would be false if it abstracted the species of a stone from its matter in such a way as to regard the species as not existing in matter, as Plato held. But it is not so, if the word "otherwise" be taken as referring to the one who understands. For it is quite true that the mode of understanding, in one who understands, is not the same as the mode of a thing in existing: since the thing understood is immaterially in the one who understands, according to the mode of the intellect, and not materially, according to the mode of a material thing.

||<b>IЄ q. 85 a. 1 ad 2 </b>Ad secundum dicendum quod quidam putaverunt quod species rei naturalis sit forma solum, et quod materia non sit pars speciei. Sed secundum hoc, in definitionibus rerum naturalium non poneretur materia. Et ideo aliter dicendum est, quod materia est duplex, scilicet communis, et signata vel individualis, communis quidem, ut caro et os; individualis autem, ut hae carnes et haec ossa. Intellectus igitur abstrahit speciem rei naturalis a materia sensibili individuali, non autem a materia sensibili communi. Sicut speciem hominis abstrahit ab his carnibus et his ossibus, quae non sunt de ratione speciei, sed sunt partes individui, ut dicitur in VII Metaphys.; et ideo sine eis considerari potest. Sed species hominis non potest abstrahi per intellectum a carnibus et ossibus. Species autem mathematicae possunt abstrahi per intellectum a materia sensibili non solum individuali, sed etiam communi; non tamen a materia intelligibili communi, sed solum individuali. Materia enim sensibilis dicitur materia corporalis secundum quod subiacet qualitatibus sensibilibus, scilicet calido et frigido, duro et molli, et huiusmodi. Materia vero intelligibilis dicitur substantia secundum quod subiacet quantitati. Manifestum est autem quod quantitas prius inest substantiae quam qualitates sensibiles. Unde quantitates, ut numeri et dimensiones et figurae, quae sunt terminationes quantitatum, possunt considerari absque qualitatibus sensibilibus, quod est eas abstrahi a materia sensibili, non tamen possunt considerari sine intellectu substantiae quantitati subiectae, quod esset eas abstrahi a materia intelligibili communi. Possunt tamen considerari sine hac vel illa substantia; quod est eas abstrahi a materia intelligibili individuali. Quaedam vero sunt quae possunt abstrahi etiam a materia intelligibili communi, sicut ens, unum, potentia et actus, et alia huiusmodi, quae etiam esse possunt absque omni materia, ut patet in substantiis immaterialibus. Et quia Plato non consideravit quod dictum est de duplici modo abstractionis, omnia quae diximus abstrahi per intellectum, posuit abstracta esse secundum rem. ||Reply to Objection 2. Some have thought that the species of a natural thing is a form only, and that matter is not part of the species. If that were so, matter would not enter into the definition of natural things. Therefore it must be said otherwise, that matter is twofold, common, and "signate" or individual; common, such as flesh and bone; and individual, as this flesh and these bones. The intellect therefore abstracts the species of a natural thing from the individual sensible matter, but not from the common sensible matter; for example, it abstracts the species of man from "this flesh and these bones," which do not belong to the species as such, but to the individual (Metaph. vii, Did. vi, 10), and need not be considered in the species: whereas the species of man cannot be abstracted by the intellect form "flesh and bones." Mathematical species, however, can be abstracted by the intellect from sensible matter, not only from individual, but also from common matter; not from common intelligible matter, but only from individual matter. For sensible matter is corporeal matter as subject to sensible qualities, such as being cold or hot, hard or soft, and the like: while intelligible matter is substance as subject to quantity. Now it is manifest that quantity is in substance before other sensible qualities are. Hence quantities, such as number, dimension, and figures, which are the terminations of quantity, can be considered apart from sensible qualities; and this is to abstract them from sensible matter; but they cannot be considered without understanding the substance which is subject to the quantity; for that would be to abstract them from common intelligible matter. Yet they can be considered apart from this or that substance; for that is to abstract them from individual intelligible matter. But some things can be abstracted even from common intelligible matter, such as "being," "unity," "power," "act," and the like; all these can exist without matter, as is plain regarding immaterial things. Because Plato failed to consider the twofold kind of abstraction, as above explained (ad 1), he held that all those things which we have stated to be abstracted by the intellect, are abstract in reality.

||<b>IЄ q. 85 a. 1 ad 3 </b>Ad tertium dicendum quod colores habent eundem modum existendi prout sunt in materia corporali individuali, sicut et potentia visiva, et ideo possunt imprimere suam similitudinem in visum. Sed phantasmata, cum sint similitudines individuorum, et existant in organis corporeis, non habent eundem modum existendi quem habet intellectus humanus, ut ex dictis patet; et ideo non possunt sua virtute imprimere in intellectum possibilem. Sed virtute intellectus agentis resultat quaedam similitudo in intellectu possibili ex conversione intellectus agentis supra phantasmata, quae quidem est repraesentativa eorum quorum sunt phantasmata, solum quantum ad naturam speciei. Et per hunc modum dicitur abstrahi species intelligibilis a phantasmatibus, non quod aliqua eadem numero forma, quae prius fuit in phantasmatibus, postmodum fiat in intellectu possibili, ad modum quo corpus accipitur ab uno loco et transfertur ad alterum. ||Reply to Objection 3. Colors, as being in individual corporeal matter, have the same mode of existence as the power of sight: therefore they can impress their own image on the eye. But phantasms, since they are images of individuals, and exist in corporeal organs, have not the same mode of existence as the human intellect, and therefore have not the power of themselves to make an impression on the passive intellect. This is done by the power of the active intellect which by turning towards the phantasm produces in the passive intellect a certain likeness which represents, as to its specific conditions only, the thing reflected in the phantasm. It is thus that the intelligible species is said to be abstracted from the phantasm; not that the identical form which previously was in the phantasm is subsequently in the passive intellect, as a body transferred from one place to another.

Not only does the active intellect throw light on the phantasm: it does more; by its own power it abstracts the intelligible species from the phantasm. It throws light on the phantasm, because, just as the sensitive part acquires a greater power by its conjunction with the intellectual part, so by the power of the active intellect the phantasms are made more fit for the abstraction therefrom of intelligible intentions. Furthermore, the active intellect abstracts the intelligible species from the phantasm, forasmuch as by the power of the active intellect we are able to disregard the conditions of individuality, and to take into our consideration the specific nature, the image of which informs the passive intellect.

Our intellect both abstracts the intelligible species from the phantasms, inasmuch as it considers the natures of things in universal, and, nevertheless, understands these natures in the phantasms since it cannot understand even the things of which it abstracts the species, without turning to the phantasms, as we have said above (84, 7).

It would seem that the intelligible species abstracted from the phantasm is related to our intellect as that which is understood.

||<b>IЄ q. 85 a. 2 co. </b>Respondeo dicendum quod quidam posuerunt quod vires cognoscitivae quae sunt in nobis, nihil cognoscunt nisi proprias passiones; puta quod sensus non sentit nisi passionem sui organi. Et secundum hoc, intellectus nihil intelligit nisi suam passionem, idest speciem intelligibilem in se receptam. Et secundum hoc, species huiusmodi est ipsum quod intelligitur. Sed haec opinio manifeste apparet falsa ex duobus. Primo quidem, quia eadem sunt quae intelligimus, et de quibus sunt scientiae. Si igitur ea quae intelligimus essent solum species quae sunt in anima, sequeretur quod scientiae omnes non essent de rebus quae sunt extra animam, sed solum de speciebus intelligibilibus quae sunt in anima; sicut secundum Platonicos omnes scientiae sunt de ideis, quas ponebant esse intellecta in actu. Secundo, quia sequeretur error antiquorum dicentium quod omne quod videtur est verum; et sic quod contradictoriae essent simul verae. Si enim potentia non cognoscit nisi propriam passionem, de ea solum iudicat. Sic autem videtur aliquid, secundum quod potentia cognoscitiva afficitur. Semper ergo iudicium potentiae cognoscitivae erit de eo quod iudicat, scilicet de propria passione, secundum quod est; et ita omne iudicium erit verum. Puta si gustus non sentit nisi propriam passionem, cum aliquis habens sanum gustum iudicat mel esse dulce, vere iudicabit; et similiter si ille qui habet gustum infectum, iudicet mel esse amarum, vere iudicabit, uterque enim iudicat secundum quod gustus eius afficitur. Et sic sequitur quod omnis opinio aequaliter erit vera, et universaliter omnis acceptio. Et ideo dicendum est quod species intelligibilis se habet ad intellectum ut quo intelligit intellectus. Quod sic patet. Cum enim sit duplex actio, sicut dicitur IX Metaphys., una quae manet in agente, ut videre et intelligere, altera quae transit in rem exteriorem, ut calefacere et secare; utraque fit secundum aliquam formam. Et sicut forma secundum quam provenit actio tendens in rem exteriorem, est similitudo obiecti actionis, ut calor calefacientis est similitudo calefacti; similiter forma secundum quam provenit actio manens in agente, est similitudo obiecti. Unde similitudo rei visibilis est secundum quam visus videt; et similitudo rei intellectae, quae est species intelligibilis, est forma secundum quam intellectus intelligit. Sed quia intellectus supra seipsum reflectitur, secundum eandem reflexionem intelligit et suum intelligere, et speciem qua intelligit. Et sic species intellectiva secundario est id quod intelligitur. Sed id quod intelligitur primo, est res cuius species intelligibilis est similitudo. Et hoc etiam patet ex antiquorum opinione, qui ponebant simile simili cognosci. Ponebant enim quod anima per terram quae in ipsa erat, cognosceret terram quae extra ipsam erat; et sic de aliis. Si ergo accipiamus speciem terrae loco terrae, secundum doctrinam Aristotelis, qui dicit quod lapis non est in anima, sed species lapidis; sequetur quod anima per species intelligibiles cognoscat res quae sunt extra animam. ||I answer that, Some have asserted that our intellectual faculties know only the impression made on them; as, for example, that sense is cognizant only of the impression made on its own organ. According to this theory, the intellect understands only its own impression, namely, the intelligible species which it has received, so that this species is what is understood. This is, however, manifestly false for two reasons. First, because the things we understand are the objects of science; therefore if what we understand is merely the intelligible species in the soul, it would follow that every science would not be concerned with objects outside the soul, but only with the intelligible species within the soul; thus, according to the teaching of the Platonists all science is about ideas, which they held to be actually understood [84, 1]. Secondly, it is untrue, because it would lead to the opinion of the ancients who maintained that "whatever seems, is true" [Aristotle, Metaph. iii. 5, and that consequently contradictories are true simultaneously. For if the faculty knows its own impression only, it can judge of that only. Now a thing seems according to the impression made on the cognitive faculty. Consequently the cognitive faculty will always judge of its own impression as such; and so every judgment will be true: for instance, if taste perceived only its own impression, when anyone with a healthy taste perceives that honey is sweet, he would judge truly; and if anyone with a corrupt taste perceives that honey is bitter, this would be equally true; for each would judge according to the impression on his taste. Thus every opinion would be equally true; in fact, every sort of apprehension. Therefore it must be said that the intelligible species is related to the intellect as that by which it understands: which is proved thus. There is a twofold action (Metaph. ix, Did. viii, 8), one which remains in the agent; for instance, to see and to understand; and another which passes into an external object; for instance, to heat and to cut; and each of these actions proceeds in virtue of some form. And as the form from which proceeds an act tending to something external is the likeness of the object of the action, as heat in the heater is a likeness of the thing heated; so the form from which proceeds an action remaining in the agent is the likeness of the object. Hence that by which the sight sees is the likeness of the visible thing; and the likeness of the thing understood, that is, the intelligible species, is the form by which the intellect understands. But since the intellect reflects upon itself, by such reflection it understands both its own act of intelligence, and the species by which it understands. Thus the intelligible species is that which is understood secondarily; but that which is primarily understood is the object, of which the species is the likeness. This also appears from the opinion of the ancient philosophers, who said that "like is known by like." For they said that the soul knows the earth outside itself, by the earth within itself; and so of the rest. If, therefore, we take the species of the earth instead of the earth, according to Aristotle (De Anima iii, 8), who says "that a stone is not in the soul, but only the likeness of the stone"; it follows that the soul knows external things by means of its intelligible species.

||<b>IЄ q. 85 a. 2 ad 1 </b>Ad primum ergo dicendum quod intellectum est in intelligente per suam similitudinem. Et per hunc modum dicitur quod intellectum in actu est intellectus in actu, inquantum similitudo rei intellectae est forma intellectus; sicut similitudo rei sensibilis est forma sensus in actu. Unde non sequitur quod species intelligibilis abstracta sit id quod actu intelligitur, sed quod sit similitudo eius. ||Reply to Objection 1. The thing understood is in the intellect by its own likeness; and it is in this sense that we say that the thing actually understood is the intellect in act, because the likeness of the thing understood is the form of the intellect, as the likeness of a sensible thing is the form of the sense in act. Hence it does not follow that the intelligible species abstracted is what is actually understood; but rather that it is the likeness thereof.

||<b>IЄ q. 85 a. 2 ad 2 </b>Ad secundum dicendum quod, cum dicitur intellectum in actu, duo importantur, scilicet res quae intelligitur, et hoc quod est ipsum intelligi. Et similiter cum dicitur universale abstractum, duo intelliguntur, scilicet ipsa natura rei, et abstractio seu universalitas. Ipsa igitur natura cui accidit vel intelligi vel abstrahi, vel intentio universalitatis, non est nisi in singularibus; sed hoc ipsum quod est intelligi vel abstrahi, vel intentio universalitatis, est in intellectu. Et hoc possumus videre per simile in sensu. Visus enim videt colorem pomi sine eius odore. Si ergo quaeratur ubi sit color qui videtur sine odore manifestum est quod color qui videtur, non est nisi in pomo; sed quod sit sine odore perceptus, hoc accidit ei ex parte visus, inquantum in visu est similitudo coloris et non odoris. Similiter humanitas quae intelligitur, non est nisi in hoc vel in illo homine, sed quod humanitas apprehendatur sine individualibus conditionibus, quod est ipsam abstrahi, ad quod sequitur intentio universalitatis, accidit humanitatis secundum quod percipitur ab intellectu, in quo est similitudo naturae speciei, et non individualium principiorum. ||Reply to Objection 2. In these words "the thing actually understood" there is a double implication--the thing which is understood, and the fact that it is understood. In like manner the words "abstract universal" imply two things, the nature of a thing and its abstraction or universality. Therefore the nature itself to which it occurs to be understood, abstracted or considered as universal is only in individuals; but that it is understood, abstracted or considered as universal is in the intellect. We see something similar to this is in the senses. For the sight sees the color of the apple apart from its smell. If therefore it be asked where is the color which is seen apart from the smell, it is quite clear that the color which is seen is only in the apple: but that it be perceived apart from the smell, this is owing to the sight, forasmuch as the faculty of sight receives the likeness of color and not of smell. In like manner humanity understood is only in this or that man; but that humanity be apprehended without conditions of individuality, that is, that it be abstracted and consequently considered as universal, occurs to humanity inasmuch as it is brought under the consideration of the intellect, in which there is a likeness of the specific nature, but not of the principles of individuality.

||<b>IЄ q. 85 a. 2 ad 3 </b>Ad tertium dicendum quod in parte sensitiva invenitur duplex operatio. Una secundum solam immutationem, et sic perficitur operatio sensus per hoc quod immutatur a sensibili. Alia operatio est formatio, secundum quod vis imaginativa format sibi aliquod idolum rei absentis, vel etiam nunquam visae. Et utraque haec operatio coniungitur in intellectu. Nam primo quidem consideratur passio intellectus possibilis secundum quod informatur specie intelligibili. Qua quidem formatus, format secundo vel definitionem vel divisionem vel compositionem, quae per vocem significatur. Unde ratio quam significat nomen, est definitio; et enuntiatio significat compositionem et divisionem intellectus. Non ergo voces significant ipsas species intelligibiles; sed ea quae intellectus sibi format ad iudicandum de rebus exterioribus. ||Reply to Objection 3. There are two operations in the sensitive part. One, in regard of impression only, and thus the operation of the senses takes place by the senses being impressed by the sensible. The other is formation, inasmuch as the imagination forms for itself an image of an absent thing, or even of something never seen. Both of these operations are found in the intellect. For in the first place there is the passion of the passive intellect as informed by the intelligible species; and then the passive intellect thus informed forms a definition, or a division, or a composition, expressed by a word. Wherefore the concept conveyed by a word is its definition; and a proposition conveys the intellect's division or composition. Words do not therefore signify the intelligible species themselves; but that which the intellect forms for itself for the purpose of judging of external things.

It would seem that the more universal is not first in our intellectual cognition. For what is first and more known in its own nature, is secondarily and less known in relation to ourselves.

||<b>IЄ q. 85 a. 3 co. </b>Respondeo dicendum quod in cognitione nostri intellectus duo oportet considerare. Primo quidem, quod cognitio intellectiva aliquo modo a sensitiva primordium sumit. Et quia sensus est singularium, intellectus autem universalium; necesse est quod cognitio singularium, quoad nos, prior sit quam universalium cognitio. Secundo oportet considerare quod intellectus noster de potentia in actum procedit. Omne autem quod procedit de potentia in actum, prius pervenit ad actum incompletum, qui est medius inter potentiam et actum, quam ad actum perfectum. Actus autem perfectus ad quem pervenit intellectus, est scientia completa, per quam distincte et determinate res cognoscuntur. Actus autem incompletus est scientia imperfecta, per quam sciuntur res indistincte sub quadam confusione, quod enim sic cognoscitur, secundum quid cognoscitur in actu, et quodammodo in potentia. Unde philosophus dicit, in I Physic., quod sunt primo nobis manifesta et certa confusa magis; posterius autem cognoscimus distinguendo distincte principia et elementa. Manifestum est autem quod cognoscere aliquid in quo plura continentur, sine hoc quod habeatur propria notitia uniuscuiusque eorum quae continentur in illo, est cognoscere aliquid sub confusione quadam. Sic autem potest cognosci tam totum universale, in quo partes continentur in potentia, quam etiam totum integrale, utrumque enim totum potest cognosci in quadam confusione, sine hoc quod partes distincte cognoscantur. Cognoscere autem distincte id quod continetur in toto universali, est habere cognitionem de re minus communi. Sicut cognoscere animal indistincte, est cognoscere animal inquantum est animal, cognoscere autem animal distincte, est cognoscere animal inquantum est animal rationale vel irrationale, quod est cognoscere hominem vel leonem. Prius igitur occurrit intellectui nostro cognoscere animal quam cognoscere hominem, et eadem ratio est si comparemus quodcumque magis universale ad minus universale. Et quia sensus exit de potentia in actum sicut et intellectus, idem etiam ordo cognitionis apparet in sensu. Nam prius secundum sensum diiudicamus magis commune quam minus commune, et secundum locum et secundum tempus. Secundum locum quidem, sicut, cum aliquid videtur a remotis, prius deprehenditur esse corpus, quam deprehendatur esse animal; et prius deprehenditur esse animal, quam deprehendatur esse homo; et prius homo, quam Socrates vel Plato. Secundum tempus autem, quia puer a principio prius distinguit hominem a non homine, quam distinguat hunc hominem ab alio homine; et ideo pueri a principio appellant omnes viros patres, posterius autem determinant unumquemque, ut dicitur in I Physic. Et huius ratio manifesta est. Quia qui scit aliquid indistincte, adhuc est in potentia ut sciat distinctionis principium; sicut qui scit genus, est in potentia ut sciat differentiam. Et sic patet quod cognitio indistincta media est inter potentiam et actum. Est ergo dicendum quod cognitio singularium est prior quoad nos quam cognitio universalium, sicut cognitio sensitiva quam cognitio intellectiva. Sed tam secundum sensum quam secundum intellectum, cognitio magis communis est prior quam cognitio minus communis. ||I answer that, In our knowledge there are two things to be considered. First, that intellectual knowledge in some degree arises from sensible knowledge: and, because sense has singular and individual things for its object, and intellect has the universal for its object, it follows that our knowledge of the former comes before our knowledge of the latter. Secondly, we must consider that our intellect proceeds from a state of potentiality to a state of actuality; and every power thus proceeding from potentiality to actuality comes first to an incomplete act, which is the medium between potentiality and actuality, before accomplishing the perfect act. The perfect act of the intellect is complete knowledge, when the object is distinctly and determinately known; whereas the incomplete act is imperfect knowledge, when the object is known indistinctly, and as it were confusedly. A thing thus imperfectly known, is known partly in act and partly in potentiality, and hence the Philosopher says (Phys. i, 1), that "what is manifest and certain is known to us at first confusedly; afterwards we know it by distinguishing its principles and elements." Now it is evident that to know an object that comprises many things, without proper knowledge of each thing contained in it, is to know that thing confusedly. In this way we can have knowledge not only of the universal whole, which contains parts potentially, but also of the integral whole; for each whole can be known confusedly, without its parts being known. But to know distinctly what is contained in the universal whole is to know the less common, as to "animal" indistinctly is to know it as "animal"; whereas to know "animal" distinctly is know it as "rational" or "irrational animal," that is, to know a man or a lion: therefore our intellect knows "animal" before it knows man; and the same reason holds in comparing any more universal idea with the less universal. Moreover, as sense, like the intellect, proceeds from potentiality to act, the same order of knowledge appears in the senses. For by sense we judge of the more common before the less common, in reference both to place and time; in reference to place, when a thing is seen afar off it is seen to be a body before it is seen to be an animal; and to be an animal before it is seen to be a man, and to be a man before it seen to be Socrates or Plato; and the same is true as regards time, for a child can distinguish man from not man before he distinguishes this man from that, and therefore "children at first call men fathers, and later on distinguish each one from the others" (Phys. i, 1). The reason of this is clear: because he who knows a thing indistinctly is in a state of potentiality as regards its principle of distinction; as he who knows "genus" is in a state of potentiality as regards "difference." Thus it is evident that indistinct knowledge is midway between potentiality and act. We must therefore conclude that knowledge of the singular and individual is prior, as regards us, to the knowledge of the universal; as sensible knowledge is prior to intellectual knowledge. But in both sense and intellect the knowledge of the more common precedes the knowledge of the less common.

||<b>IЄ q. 85 a. 3 ad 1 </b>Ad primum ergo dicendum quod universale dupliciter potest considerari. Uno modo, secundum quod natura universalis consideratur simul cum intentione universalitatis. Et cum intentio universalitatis, ut scilicet unum et idem habeat habitudinem ad multa, proveniat ex abstractione intellectus, oportet quod secundum hunc modum universale sit posterius. Unde in I de anima dicitur quod animal universale aut nihil est, aut posterius est. Sed secundum Platonem, qui posuit universalia subsistentia, secundum hanc considerationem universale esset prius quam particularia, quae secundum eum non sunt nisi per participationem universalium subsistentium, quae dicuntur ideae. Alio modo potest considerari quantum ad ipsam naturam, scilicet animalitatis vel humanitatis, prout invenitur in particularibus. Et sic dicendum est quod duplex est ordo naturae. Unus secundum viam generationis et temporis, secundum quam viam, ea quae sunt imperfecta et in potentia, sunt priora. Et hoc modo magis commune est prius secundum naturam, quod apparet manifeste in generatione hominis et animalis; nam prius generatur animal quam homo, ut dicitur in libro de Generat. Animal. Alius est ordo perfectionis, sive intentionis naturae; sicut actus simpliciter est prius secundum naturam quam potentia, et perfectum prius quam imperfectum. Et per hunc modum, minus commune est prius secundum naturam quam magis commune, ut homo quam animal, naturae enim intentio non sistit in generatione animalis, sed intendit generare hominem. ||Reply to Objection 1. The universal can be considered in two ways.  First, the universal nature may be considered together with the intention of universality. And since the intention of universality--viz. the relation of one and the same to many--is due to intellectual abstraction, the universal thus considered is a secondary consideration. Hence it is said (De Anima i, 1) that the "universal animal is either nothing or something secondary." But according to Plato, who held that universals are subsistent, the universal considered thus would be prior to the particular, for the latter, according to him, are mere participations of the subsistent universals which he called ideas. Secondly, the universal can be considered in the nature itself--for instance, animality or humanity as existing in the individual. And thus we must distinguish two orders of nature: one, by way of generation and time; and thus the imperfect and the potential come first. In this way the more common comes first in the order of nature; as appears clearly in the generation of man and animal; for "the animal is generated before man," as the Philosopher says (De Gener. Animal ii, 3). The other order is the order of perfection or of the intention of nature: for instance, act considered absolutely is naturally prior to potentiality, and the perfect to the imperfect: thus the less common comes naturally before the more common; as man comes before animal. For the intention of nature does not stop at the generation of animal but goes on to the generation of man.

Ut pars autem, secundum quod minus commune continet in sui ratione non solum magis commune, sed etiam alia; ut homo non solum animal, sed etiam rationale. Sic igitur animal consideratum in se, prius est in nostra cognitione quam homo; sed homo est prius in nostra cognitione quam quod animal sit pars rationis eius. ||Reply to Objection 2. The more common universal may be compared to the less common, as the whole, and as the part. As the whole, considering that in the more universal is potentially contained not only the less universal, but also other things, as in "animal" is contained not only "man" but also "horse." As part, considering that the less common contains in its idea not only the more common, but also more; as "man" contains not only "animal" but also "rational." Therefore "animal" in itself comes into our knowledge before "man"; but "man" comes before "animal" considered as part of the same idea.

A part can be known in two ways. First, absolutely considered in itself; and thus nothing prevents the parts being known before the whole, as stones are known before a house is known. Secondly as belonging to a certain whole; and thus we must needs know the whole before its parts. For we know a house vaguely before we know its different parts. So likewise principles of definition are known before the thing defined is known; otherwise the thing defined would not be known at all. But as parts of the definition they are known after. For we know man vaguely as man before we know how to distinguish all that belongs to human nature.

||<b>IЄ q. 85 a. 3 ad 4 </b>Ad quartum dicendum quod universale, secundum quod accipitur cum intentione universalitatis, est quidem quodammodo principium cognoscendi, prout intentio universalitatis consequitur modum intelligendi qui est per abstractionem. Non autem est necesse quod omne quod est principium cognoscendi, sit principium essendi, ut Plato existimavit, cum quandoque cognoscamus causam per effectum, et substantiam per accidentia. Unde universale sic acceptum, secundum sententiam Aristotelis, non est principium essendi, neque substantia, ut patet in VII Metaphys. Si autem consideremus ipsam naturam generis et speciei prout est in singularibus, sic quodammodo habet rationem principii formalis respectu singularium, nam singulare est propter materiam, ratio autem speciei sumitur ex forma. Sed natura generis comparatur ad naturam speciei magis per modum materialis principii, quia natura generis sumitur ab eo quod est materiale in re, ratio vero speciei ab eo quod est formale; sicut ratio animalis a sensitivo, ratio vero hominis ab intellectivo. Et inde est quod ultima naturae intentio est ad speciem, non autem ad individuum, neque ad genus, quia forma est finis generationis, materia vero est propter formam. Non autem oportet quod cuiuslibet causae vel principii cognitio sit posterior quoad nos, cum quandoque cognoscamus per causas sensibiles, effectus ignotos; quandoque autem e converso. ||Reply to Objection 4. The universal, as understood with the intention of universality, is, indeed, in a way, a principle of knowledge, in so far as the intention of universality results from the mode of understanding by way of abstraction. But what is a principle of knowledge is not of necessity a principle of existence, as Plato thought: since at times we know a cause through its effect, and substance through accidents. Wherefore the universal thus considered, according to the opinion of Aristotle, is neither a principle of existence, nor a substance, as he makes clear (Metaph. vii, Did. vi, 13). But if we consider the generic or specific nature itself as existing in the singular, thus in a way it is in the nature of a formal principle in regard to the singulars: for the singular is the result of matter, while the idea of species is from the form. But the generic nature is compared to the specific nature rather after the fashion of a material principle, because the generic nature is taken from that which is material in a thing, while the idea of species is taken from that which is formal: thus the notion of animal is taken from the sensitive part, whereas the notion of man is taken from the intellectual part. Thus it is that the ultimate intention of nature is to the species and not to the individual, or the genus: because the form is the end of generation, while matter is for the sake of the form. Neither is it necessary that, as regards us, knowledge of any cause or principle should be secondary: since at times through sensible causes we become acquainted with unknown effects, and sometimes conversely.

Nam modus cuiusque actionis consequitur formam quae est actionis principium. Quaecumque ergo intellectus potest intelligere sub una specie, simul intelligere potest, et inde est quod Deus omnia simul videt, quia omnia videt per unum, quod est essentia sua. Quaecumque vero intellectus per diversas species intelligit, non simul intelligit. Et huius ratio est, quia impossibile est idem subiectum perfici simul pluribus formis unius generis et diversarum specierum, sicut impossibile est quod idem corpus secundum idem simul coloretur diversis coloribus, vel figuretur diversis figuris. Omnes autem species intelligibiles sunt unius generis, quia sunt perfectiones unius intellectivae potentiae; licet res quarum sunt species, sint diversorum generum. Impossibile est ergo quod idem intellectus simul perficiatur diversis speciebus intelligibilibus, ad intelligendum diversa in actu. ||I answer that, The intellect can, indeed, understand many things as one, but not as many: that is to say by "one" but not by "many" intelligible species. For the mode of every action follows the form which is the principle of that action. Therefore whatever things the intellect can understand under one species, it can understand at the same time: hence it is that God sees all things at the same time, because He sees all in one, that is, in His Essence. But whatever things the intellect understands under different species, it does not understand at the same time. The reason of this is that it is impossible for one and the same subject to be perfected at the same time by many forms of one genus and diverse species, just as it is impossible for one and the same body at the same time to have different colors or different shapes. Now all intelligible species belong to one genus, because they are the perfections of one intellectual faculty: although the things which the species represent belong to different genera. Therefore it is impossible for one and the same intellect to be perfected at the same time by different intelligible species so as actually to understand different things.

||<b>IЄ q. 85 a. 5 arg. 1 </b>Ad quintum sic proceditur. Videtur quod intellectus noster non intelligat componendo et dividendo. Compositio enim et divisio non est nisi multorum. Sed intellectus non potest simul multa intelligere. Ergo non potest intelligere componendo et dividendo. ||Objection 1. It would seem that our intellect does not understand by composition and division. For composition and division are only of many; whereas the intellect cannot understand many things at the same time. Therefore it cannot understand by composition and division.

||<b>IЄ q. 85 a. 5 arg. 2 </b>Praeterea, omni compositioni et divisioni adiungitur tempus praesens, praeteritum vel futurum. Sed intellectus abstrahit a tempore, sicut etiam ab aliis particularibus conditionibus. Ergo intellectus non intelligit componendo et dividendo. ||Objection 2. Further, every composition and division implies past, present, or future time. But the intellect abstracts from time, as also from other individual conditions. Therefore the intellect does not understand by composition and division.

||<b>IЄ q. 85 a. 5 arg. 3 </b>Praeterea, intellectus intelligit per assimilationem ad res. Sed compositio et divisio nihil est in rebus, nihil enim invenitur in rebus nisi res quae significatur per praedicatum et subiectum, quae est una et eadem si compositio est vera; homo enim est vere id quod est animal. Ergo intellectus non componit et dividit. ||Objection 3. Further, the intellect understands things by a process of assimilation to them. But composition and division are not in things, for nothing is in things but what is signified by the predicate and the subject, and which is one and the same, provided that the composition be true, for "man" is truly what "animal" is. Therefore the intellect does not act by composition and division.

But in words we find composition and division, as appears in affirmative and negative propositions. Therefore the intellect acts by composition and division.

||<b>IЄ q. 85 a. 5 co. </b>Respondeo dicendum quod intellectus humanus necesse habet intelligere componendo et dividendo. Cum enim intellectus humanus exeat de potentia in actum, similitudinem quandam habet cum rebus generabilibus, quae non statim perfectionem suam habent, sed eam successive acquirunt. Et similiter intellectus humanus non statim in prima apprehensione capit perfectam rei cognitionem; sed primo apprehendit aliquid de ipsa, puta quidditatem ipsius rei, quae est primum et proprium obiectum intellectus; et deinde intelligit proprietates et accidentia et habitudines circumstantes rei essentiam. Et secundum hoc, necesse habet unum apprehensum alii componere vel dividere; et ex una compositione vel divisione ad aliam procedere, quod est ratiocinari. Intellectus autem angelicus et divinus se habet sicut res incorruptibiles, quae statim a principio habent suam totam perfectionem. Unde intellectus angelicus et divinus statim perfecte totam rei cognitionem habet. Unde in cognoscendo quidditatem rei, cognoscit de re simul quidquid nos cognoscere possumus componendo et dividendo et ratiocinando. Et ideo intellectus humanus cognoscit componendo et dividendo, sicut et ratiocinando. Intellectus autem divinus et angelicus cognoscunt quidem compositionem et divisionem et ratiocinationem, non componendo et dividendo et ratiocinando, sed per intellectum simplicis quidditatis. ||I answer that, The human intellect must of necessity understand by composition and division. For since the intellect passes from potentiality to act, it has a likeness to things which are generated, which do not attain to perfection all at once but acquire it by degrees: so likewise the human intellect does not acquire perfect knowledge by the first act of apprehension; but it first apprehends something about its object, such as its quiddity, and this is its first and proper object; and then it understands the properties, accidents, and the various relations of the essence. Thus it necessarily compares one thing with another by composition or division; and from one composition and division it proceeds to another, which is the process of reasoning. But the angelic and the Divine intellect, like all incorruptible things, have their perfection at once from the beginning. Hence the angelic and the Divine intellect have the entire knowledge of a thing at once and perfectly; and hence also in knowing the quiddity of a thing they know at once whatever we can know by composition, division, and reasoning. Therefore the human intellect knows by composition, division and reasoning. But the Divine intellect and the angelic intellect know, indeed, composition, division, and reasoning, not by the process itself, but by understanding the simple essence.

||<b>IЄ q. 85 a. 5 ad 1 </b>Ad primum ergo dicendum quod compositio et divisio intellectus secundum quandam differentiam vel comparationem fit. Unde sic intellectus cognoscit multa componendo et dividendo, sicut cognoscendo differentiam vel comparationem rerum. ||Reply to Objection 1. Composition and division of the intellect are made by differentiating and comparing. Hence the intellect knows many things by composition and division, as by knowing the difference and comparison of things.

||<b>IЄ q. 85 a. 5 ad 2 </b>Ad secundum dicendum quod intellectus et abstrahit a phantasmatibus; et tamen non intelligit actu nisi convertendo se ad phantasmata, sicut supra dictum est. Et ex ea parte qua se ad phantasmata convertit, compositioni et divisioni intellectus adiungitur tempus. ||Reply to Objection 2. Although the intellect abstracts from the phantasms, it does not understand actually without turning to the phantasms, as we have said (1; 84, 7). And forasmuch as it turns to the phantasms, composition and division of the intellect involve time.

||<b>IЄ q. 85 a. 5 ad 3 </b>Ad tertium dicendum quod similitudo rei recipitur in intellectu secundum modum intellectus, et non secundum modum rei. Unde compositioni et divisioni intellectus respondet quidem aliquid ex parte rei; tamen non eodem modo se habet in re, sicut in intellectu. Intellectus enim humani proprium obiectum est quidditas rei materialis, quae sub sensu et imaginatione cadit. Invenitur autem duplex compositio in re materiali. Prima quidem, formae ad materiam, et huic respondet compositio intellectus qua totum universale de sua parte praedicatur; nam genus sumitur a materia communi, differentia vero completiva speciei a forma, particulare vero a materia individuali. Secunda vero compositio est accidentis ad subiectum, et huic reali compositioni respondet compositio intellectus secundum quam praedicatur accidens de subiecto, ut cum dicitur, homo est albus. Tamen differt compositio intellectus a compositione rei, nam ea quae componuntur in re, sunt diversa; compositio autem intellectus est signum identitatis eorum quae componuntur. Non enim intellectus sic componit, ut dicat quod homo est albedo; sed dicit quod homo est albus, idest habens albedinem, idem autem est subiecto quod est homo, et quod est habens albedinem. Et simile est de compositione formae et materiae, nam animal significat id quod habet naturam sensitivam, rationale vero quod habet naturam intellectivam, homo vero quod habet utrumque, Socrates vero quod habet omnia haec cum materia individuali; et secundum hanc identitatis rationem, intellectus noster unum componit alteri praedicando. ||Reply to Objection 3. The likeness of a thing is received into the intellect according to the mode of the intellect, not according to the mode of the thing. Wherefore something on the part of the thing corresponds to the composition and division of the intellect; but it does not exist in the same way in the intellect and in the thing. For the proper object of the human intellect is the quiddity of a material thing, which comes under the action of the senses and the imagination. Now in a material thing there is a twofold composition. First, there is the composition of form with matter; and to this corresponds that composition of the intellect whereby the universal whole is predicated of its part: for the genus is derived from common matter, while the difference that completes the species is derived from the form, and the particular from individual matter. The second comparison is of accident with subject: and to this real composition corresponds that composition of the intellect, whereby accident is predicated of subject, as when we say "the man is white." Nevertheless composition of the intellect differs from composition of things; for in the latter the things are diverse, whereas composition of the intellect is a sign of the identity of the components. For the above composition of the intellect does not imply that "man" and "whiteness" are identical, but the assertion, "the man is white," means that "the man is something having whiteness": and the subject, which is a man, is identified with a subject having whiteness. It is the same with the composition of form and matter: for animal signifies that which has a sensitive nature; rational, that which has an intellectual nature; man, that which has both; and Socrates that which has all these things together with individual matter; and according to this kind of identity our intellect predicates the composition of one thing with another.

It would seem that the intellect can be false; for the Philosopher says (Metaph. vi, Did. v, 4) that "truth and falsehood are in the mind."

||<b>IЄ q. 85 a. 6 co. </b>Respondeo dicendum quod philosophus, in III de anima, comparat, quantum ad hoc, intellectum sensui. Sensus enim circa proprium obiectum non decipitur, sicut visus circa colorem; nisi forte per accidens, ex impedimento circa organum contingente, sicut cum gustus febrientium dulcia iudicat amara, propter hoc quod lingua malis humoribus est repleta. Circa sensibilia vero communia decipitur sensus, sicut in diiudicando de magnitudine vel figura; ut cum iudicat solem esse pedalem, qui tamen est maior terra. Et multo magis decipitur circa sensibilia per accidens; ut cum iudicat fel esse mel, propter coloris similitudinem. Et huius ratio est in evidenti. Quia ad proprium obiectum unaquaeque potentia per se ordinatur, secundum quod ipsa. Quae autem sunt huiusmodi, semper eodem modo se habent. Unde manente potentia, non deficit eius iudicium circa proprium obiectum. Obiectum autem proprium intellectus est quidditas rei. Unde circa quidditatem rei, per se loquendo, intellectus non fallitur. Sed circa ea quae circumstant rei essentiam vel quidditatem, intellectus potest falli, dum unum ordinat ad aliud, vel componendo vel dividendo vel etiam ratiocinando. Et propter hoc etiam circa illas propositiones errare non potest, quae statim cognoscuntur cognita terminorum quidditate, sicut accidit circa prima principia, ex quibus etiam accidit infallibilitas veritatis, secundum certitudinem scientiae, circa conclusiones. Per accidens tamen contingit intellectum decipi circa quod quid est in rebus compositis; non ex parte organi, quia intellectus non est virtus utens organo; sed ex parte compositionis intervenientis circa definitionem, dum vel definitio unius rei est falsa de alia, sicut definitio circuli de triangulo, vel dum aliqua definitio in seipsa est falsa, implicans compositionem impossibilium, ut si accipiatur hoc ut definitio alicuius rei, animal rationale alatum. Unde in rebus simplicibus, in quarum definitionibus compositio intervenire non potest, non possumus decipi; sed deficimus in totaliter non attingendo, sicut dicitur in IX Metaphys. ||I answer that, The Philosopher (De Anima iii, 6) compares intellect with sense on this point. For sense is not deceived in its proper object, as sight in regard to color; has accidentally through some hindrance occurring to the sensile organ--for example, the taste of a fever-stricken person judges a sweet thing to be bitter, through his tongue being vitiated by ill humors. Sense, however, may be deceived as regards common sensible objects, as size or figure; when, for example, it judges the sun to be only a foot in diameter, whereas in reality it exceeds the earth in size. Much more is sense deceived concerning accidental sensible objects, as when it judges that vinegar is honey by reason of the color being the same. The reason of this is evident; for every faculty, as such, is "per se" directed to its proper object; and things of this kind are always the same. Hence, as long as the faculty exists, its judgment concerning its own proper object does not fail. Now the proper object of the intellect is the "quiddity" of a material thing; and hence, properly speaking, the intellect is not at fault concerning this quiddity; whereas it may go astray as regards the surroundings of the thing in its essence or quiddity, in referring one thing to another, as regards composition or division, or also in the process of reasoning. Therefore, also in regard to those propositions, which are understood, the intellect cannot err, as in the case of first principles from which arises infallible truth in the certitude of scientific conclusions. The intellect, however, may be accidentally deceived in the quiddity of composite things, not by the defect of its organ, for the intellect is a faculty that is independent of an organ; but on the part of the composition affecting the definition, when, for instance, the definition of a thing is false in relation to something else, as the definition of a circle applied to a triangle; or when a definition is false in itself as involving the composition of things incompatible; as, for instance, to describe anything as "a rational winged animal." Hence as regards simple objects not subject to composite definitions we cannot be deceived unless, indeed, we understand nothing whatever about them, as is said Metaph. ix, Did. viii, 10.

||<b>IЄ q. 85 a. 7 arg. 1 </b>Ad septimum sic proceditur. Videtur quod unam et eandem rem unus alio melius intelligere non possit. Dicit enim Augustinus, in libro octoginta trium quaest., quisquis ullam rem aliter quam est intelligit non eam intelligit. Quare non est dubitandum esse perfectam intelligentiam, qua praestantior esse non possit; et ideo non per infinitum ire quod quaelibet res intelligitur; nec eam posse alium alio plus intelligere. ||Objection 1. It would seem that one person cannot understand one and the same thing better than another can. For Augustine says (QQ. 83, qu. 32), "Whoever understands a thing otherwise than as it is, does not understand it at all. Hence it is clear that there is a perfect understanding, than which none other is more perfect: and therefore there are not infinite degrees of understanding a thing: nor can one person understand a thing better than another can."

||<b>IЄ q. 85 a. 7 co. </b>Respondeo dicendum quod aliquem intelligere unam et eandem rem magis quam alium, potest intelligi dupliciter. Uno modo, sic quod ly magis determinet actum intelligendi ex parte rei intellectae. Et sic non potest unus eandem rem magis intelligere quam alius, quia si intelligeret eam aliter esse quam sit, vel melius vel peius, falleretur, et non intelligeret ut arguit Augustinus. Alio modo potest intelligi ut determinet actum intelligendi ex parte intelligentis. Et sic unus alio potest eandem rem melius intelligere, quia est melioris virtutis in intelligendo; sicut melius videt visione corporali rem aliquam qui est perfectioris virtutis, et in quo virtus visiva est perfectior. Hoc autem circa intellectum contingit dupliciter. Uno quidem modo, ex parte ipsius intellectus, qui est perfectior. Manifestum est enim quod quanto corpus est melius dispositum, tanto meliorem sortitur animam, quod manifeste apparet in his quae sunt secundum speciem diversa. Cuius ratio est, quia actus et forma recipitur in materia secundum materiae capacitatem. Unde cum etiam in hominibus quidam habeant corpus melius dispositum, sortiuntur animam maioris virtutis in intelligendo, unde dicitur in II de anima quod molles carne bene aptos mente videmus. Alio modo contingit hoc ex parte inferiorum virtutum, quibus intellectus indiget ad sui operationem, illi enim in quibus virtus imaginativa et cogitativa et memorativa est melius disposita, sunt melius dispositi ad intelligendum. ||I answer that, A thing being understood more by one than by another may be taken in two senses. First, so that the word "more" be taken as determining the act of understanding as regards the thing understood; and thus, one cannot understand the same thing more than another, because to understand it otherwise than as it is, either better or worse, would entail being deceived, and such a one would not understand it, as Augustine argues (QQ. 83, qu. 32). In another sense the word "more" can be taken as determining the act of understanding on the part of him who understands; and so one may understand the same thing better than someone else, through having a greater power of understanding: just as a man may see a thing better with his bodily sight, whose power is greater, and whose sight is more perfect. The same applies to the intellect in two ways. First, as regards the intellect itself, which is more perfect. For it is plain that the better the disposition of a body, the better the soul allotted to it; which clearly appears in things of different species: and the reason thereof is that act and form are received into matter according to matter's capacity: thus because some men have bodies of better disposition, their souls have a greater power of understanding, wherefore it is said (De Anima ii, 9), that "it is to be observed that those who have soft flesh are of apt mind." Secondly, this occurs in regard to the lower powers of which the intellect has need in its operation: for those in whom the imaginative, cogitative, and memorative powers are of better disposition, are better disposed to understand.

||<b>IЄ q. 85 a. 8 arg. 1 </b>Ad octavum sic proceditur. Videtur quod intellectus noster per prius cognoscat indivisibile quam divisibile. Dicit enim philosophus, in I Physic., quod intelligimus et scimus ex principiorum et elementorum cognitione. Sed indivisibilia sunt principia et elementa divisibilium. Ergo per prius sunt nobis nota indivisibilia quam divisibilia. ||Objection 1. It would seem that the intellect understands the indivisible before the divisible. For the Philosopher says (Phys. i, 1) that "we understand and know from the knowledge of principles and elements." But principles are indivisible, and elements are of divisible things. Therefore the indivisible is known to us before the divisible.

Et unitas ponitur in definitione numeri, quia numerus est multitudo mensurata per unum, ut dicitur in X Metaphys. Ergo intellectus noster per prius intelligit indivisibile quam divisibile. ||Objection 2. Further, the definition of a thing contains what is known previously, for a definition "proceeds from the first and more known," as is said Topic. vi, 4. But the indivisible is part of the definition of the divisible; as a point comes into the definition of a line; for as Euclid says, "a line is length without breadth, the extremities of which are points"; also unity comes into the definition of number, for "number is multitude measured by one," as is said Metaph. x, Did. ix, 6.

||<b>IЄ q. 85 a. 8 co. </b>Respondeo dicendum quod obiectum intellectus nostri, secundum praesentem statum, est quidditas rei materialis, quam a phantasmatibus abstrahit, ut ex praemissis patet. Et quia id quod est primo et per se cognitum a virtute cognoscitiva, est proprium eius obiectum, considerari potest quo ordine indivisibile intelligatur a nobis, ex eius habitudine ad huiusmodi quidditatem. Dicitur autem indivisibile tripliciter, ut dicitur in III de anima. Uno modo, sicut continuum est indivisibile, quia est indivisum in actu, licet sit divisibile in potentia. Et huiusmodi indivisibile prius est intellectum a nobis quam eius divisio, quae est in partes, quia cognitio confusa est prior quam distincta, ut dictum est. Alio modo dicitur indivisibile secundum speciem, sicut ratio hominis est quoddam indivisibile. Et hoc etiam modo indivisibile est prius intellectum quam divisio eius in partes rationis, ut supra dictum est, et iterum prius quam intellectus componat et dividat, affirmando vel negando. Et huius ratio est, quia huiusmodi duplex indivisibile intellectus secundum se intelligit, sicut proprium obiectum. Tertio modo dicitur indivisibile quod est omnino indivisibile, ut punctus et unitas, quae nec actu nec potentia dividuntur. Et huiusmodi indivisibile per posterius cognoscitur, per privationem divisibilis. Unde punctum privative definitur, punctum est cuius pars non est, et similiter ratio unius est quod sit indivisibile, ut dicitur in X Metaphys. Et huius ratio est, quia tale indivisibile habet quandam oppositionem ad rem corporalem, cuius quidditatem primo et per se intellectus accipit. Si autem intellectus noster intelligeret per participationem indivisibilium separatorum, ut Platonici posuerunt, sequeretur quod indivisibile huiusmodi esset primo intellectum, quia secundum Platonicos, priora prius participantur a rebus. ||I answer that, The object of our intellect in its present state is the quiddity of a material thing, which it abstracts from the phantasms, as above stated (84, 7). And since that which is known first and of itself by our cognitive power is its proper object, we must consider its relationship to that quiddity in order to discover in what order the indivisible is known. Now the indivisible is threefold, as is said De Anima iii, 6. First, the continuous is indivisible, since actually it is undivided, although potentially divisible: and this indivisible is known to us before its division, which is a division into parts: because confused knowledge is prior to distinct knowledge, as we have said above (3). Secondly, the indivisible is so called in relation to species, as man's reason is something indivisible. This way, also, the indivisible is understood before its division into logical parts, as we have said above (De Anima iii, 6); and again before the intellect disposes and divides by affirmation and negation. The reason of this is that both these kinds of indivisible are understood by the intellect of itself, as being its proper object. The third kind of indivisible is what is altogether indivisible, as a point and unity, which cannot be divided either actually or potentially. And this indivisible is known secondarily, through the privation of divisibility. Wherefore a point is defined by way of privation "as that which has no parts"; and in like manner the notion of "one" is that is "indivisible," as stated in Metaph. x, Did. ix, 1. And the reason of this is that this indivisible has a certain opposition to a corporeal being, the quiddity of which is the primary and proper object of the intellect. But if our intellect understood by participation of certain separate indivisible (forms), as the Platonists maintained, it would follow that a like indivisible is understood primarily; for according to the Platonists what is first is first participated by things.

A point is not included in the definition of a line in general: for it is manifest that in a line of indefinite length, and in a circular line, there is no point, save potentially. Euclid defines a finite straight line: and therefore he mentions a point in the definition, as the limit in the definition of that which is limited. Unity is the measure of number: wherefore it is included in the definition of a measured number. But it is not included in the definition of the divisible, but rather conversely.

||<b>IЄ q. 86 a. 1 co. </b>Respondeo dicendum quod singulare in rebus materialibus intellectus noster directe et primo cognoscere non potest. Cuius ratio est, quia principium singularitatis in rebus materialibus est materia individualis, intellectus autem noster, sicut supra dictum est, intelligit abstrahendo speciem intelligibilem ab huiusmodi materia. Quod autem a materia individuali abstrahitur, est universale. Unde intellectus noster directe non est cognoscitivus nisi universalium. Indirecte autem, et quasi per quandam reflexionem, potest cognoscere singulare, quia, sicut supra dictum est, etiam postquam species intelligibiles abstraxit, non potest secundum eas actu intelligere nisi convertendo se ad phantasmata, in quibus species intelligibiles intelligit, ut dicitur in III de anima. Sic igitur ipsum universale per speciem intelligibilem directe intelligit; indirecte autem singularia, quorum sunt phantasmata. Et hoc modo format hanc propositionem, Socrates est homo. ||I answer that, Our intellect cannot know the singular in material things directly and primarily. The reason of this is that the principle of singularity in material things is individual matter, whereas our intellect, as have said above (85, 1), understands by abstracting the intelligible species from such matter. Now what is abstracted from individual matter is the universal. Hence our intellect knows directly the universal only. But indirectly, and as it were by a kind of reflection, it can know the singular, because, as we have said above (85, 7), even after abstracting the intelligible species, the intellect, in order to understand, needs to turn to the phantasms in which it understands the species, as is said De Anima iii, 7. Therefore it understands the universal directly through the intelligible species, and indirectly the singular represented by the phantasm. And thus it forms the proposition "Socrates is a man."

The choice of a particular thing to be done is as the conclusion of a syllogism formed by the practical intellect, as is said Ethic. vii, 3. But a singular proposition cannot be directly concluded from a universal proposition, except through the medium of a singular proposition. Therefore the universal principle of the practical intellect does not move save through the medium of the particular apprehension of the sensitive part, as is said De Anima iii, 11.

Intelligibility is incompatible with the singular not as such, but as material, for nothing can be understood otherwise than immaterially.

|- valign = top
 
||<b>IЄ q. 86 a. 2 co. </b>Respondeo dicendum quod, cum potentia proportionetur suo obiecto, oportet hoc modo se habere intellectum ad infinitum, sicut se habet eius obiectum, quod est quidditas rei materialis. In rebus autem materialibus non invenitur infinitum in actu, sed solum in potentia, secundum quod unum succedit alteri, ut dicitur in III Physic. Et ideo in intellectu nostro invenitur infinitum in potentia, in accipiendo scilicet unum post aliud, quia nunquam intellectus noster tot intelligit, quin possit plura intelligere. Actu autem vel habitu non potest cognoscere infinita intellectus noster. Actu quidem non, quia intellectus noster non potest simul actu cognoscere nisi quod per unam speciem cognoscit. Infinitum autem non habet unam speciem, alioquin haberet rationem totius et perfecti. Et ideo non potest intelligi nisi accipiendo partem post partem, ut ex eius definitione patet in III Physic., est enim infinitum cuius quantitatem accipientibus semper est aliquid extra accipere, et sic infinitum cognosci non posset actu, nisi omnes partes eius numerarentur, quod est impossibile. Et eadem ratione non possumus intelligere infinita in habitu. In nobis enim habitualis cognitio causatur ex actuali consideratione, intelligendo enim efficimur scientes, ut dicitur in II Ethic. Unde non possemus habere habitum infinitorum secundum distinctam cognitionem, nisi consideravissemus omnia infinita, numerando ea secundum cognitionis successionem, quod est impossibile. Et ita nec actu nec habitu intellectus noster potest cognoscere infinita, sed in potentia tantum, ut dictum est. ||I answer that, Since a faculty and its object are proportional to each other, the intellect must be related to the infinite, as is its object, which is the quiddity of a material thing. Now in material things the infinite does not exist actually, but only potentially, in the sense of one succeeding another, as is said Phys. iii, 6. Therefore infinity is potentially in our mind through its considering successively one thing after another: because never does our intellect understand so many things, that it cannot understand more. On the other hand, our intellect cannot understand the infinite either actually or habitually. Not actually, for our intellect cannot know actually at the same time, except what it knows through one species. But the infinite is not represented by one species, for if it were it would be something whole and complete. Consequently it cannot be understood except by a successive consideration of one part after another, as is clear from its definition (Phys. iii, 6): for the infinite is that "from which, however much we may take, there always remains something to be taken." Thus the infinite could not be known actually, unless all its parts were counted: which is impossible. For the same reason we cannot have habitual knowledge of the infinite: because in us habitual knowledge results from actual consideration: since by understanding we acquire knowledge, as is said Ethic. ii, 1. Wherefore it would not be possible for us to have a habit of an infinity of things distinctly known, unless we had already considered the entire infinity thereof, counting them according to the succession of our knowledge: which is impossible. And therefore neither actually nor habitually can our intellect know the infinite, but only potentially as explained above.

||<b>IЄ q. 86 a. 2 ad 1 </b>Ad primum ergo dicendum quod, sicut supra dictum est, Deus dicitur infinitus sicut forma quae non est terminata per aliquam materiam, in rebus autem materialibus aliquid dicitur infinitum per privationem formalis terminationis. Et quia forma secundum se nota est, materia autem sine forma ignota, inde est quod infinitum materiale est secundum se ignotum. Infinitum autem formale, quod est Deus, est secundum se notum, ignotum autem quoad nos, propter defectum intellectus nostri, qui secundum statum praesentis vitae habet naturalem aptitudinem ad materialia cognoscenda. Et ideo in praesenti Deum cognoscere non possumus nisi per materiales effectus. In futuro autem tolletur defectus intellectus nostri per gloriam, et tunc ipsum Deum in sua essentia videre poterimus, tamen absque comprehensione. ||Reply to Objection 1. As we have said above (7, 1), God is called infinite, because He is a form unlimited by matter; whereas in material things, the term 'infinite' is applied to that which is deprived of any formal term. And form being known in itself, whereas matter cannot be known without form, it follows that the material infinite is in itself unknowable. But the formal infinite, God, is of Himself known; but He is unknown to us by reason of our feeble intellect, which in its present state has a natural aptitude for material objects only. Therefore we cannot know God in our present life except through material effects. In the future life this defect of intellect will be removed by the state of glory, when we shall be able to see the Essence of God Himself, but without being able to comprehend Him.

If two or more bodies were in the same place, there would be no need for them to occupy the place successively, in order for the things placed to be counted according to this succession of occupation.

As our intellect is infinite in power, so does it know the infinite. For its power is indeed infinite inasmuch as it is not terminated by corporeal matter.

Further, as stated in Phys. iv, 12, "what sometimes is and sometimes is not, is measured by time." Now the intellect abstracts from time, and from other material conditions.

||<b>IЄ q. 86 a. 3 co. </b>Respondeo dicendum quod contingentia dupliciter possunt considerari. Uno modo, secundum quod contingentia sunt. Alio modo, secundum quod in eis aliquid necessitatis invenitur, nihil enim est adeo contingens, quin in se aliquid necessarium habeat. Sicut hoc ipsum quod est Socratem currere, in se quidem contingens est; sed habitudo cursus ad motum est necessaria, necessarium enim est Socratem moveri, si currit. Est autem unumquodque contingens ex parte materiae, quia contingens est quod potest esse et non esse; potentia autem pertinet ad materiam. Necessitas autem consequitur rationem formae, quia ea quae consequuntur ad formam, ex necessitate insunt. Materia autem est individuationis principium, ratio autem universalis accipitur secundum abstractionem formae a materia particulari. Dictum autem est supra quod per se et directe intellectus est universalium; sensus autem singularium, quorum etiam indirecte quodammodo est intellectus, ut supra dictum est. Sic igitur contingentia, prout sunt contingentia, cognoscuntur directe quidem sensu, indirecte autem ab intellectu, rationes autem universales et necessariae contingentium cognoscuntur per intellectum. Unde si attendantur rationes universales scibilium, omnes scientiae sunt de necessariis. Si autem attendantur ipsae res, sic quaedam scientia est de necessariis, quaedam vero de contingentibus. ||I answer that, Contingent things can be considered in two ways; either as contingent, or as containing some element of necessity, since every contingent thing has in it something necessary: for example, that Socrates runs, is in itself contingent; but the relation of running to motion is necessary, for it is necessary that Socrates move if he runs. Now contingency arises from matter, for contingency is a potentiality to be or not to be, and potentiality belongs to matter; whereas necessity results from form, because whatever is consequent on form is of necessity in the subject. But matter is the individualizing principle: whereas the universal comes from the abstraction of the form from the particular matter. Moreover it was laid down above (1) that the intellect of itself and directly has the universal for its object; while the object of sense is the singular, which in a certain way is the indirect object of the intellect, as we have said above (1). Therefore the contingent, considered as such, is known directly by sense and indirectly by the intellect; while the universal and necessary principles of contingent things are known only by the intellect. Hence if we consider the objects of science in their universal principles, then all science is of necessary things. But if we consider the things themselves, thus some sciences are of necessary things, some of contingent things.

Rationes autem futurorum possunt esse universales, et intellectu perceptibiles, et de eis etiam possunt esse scientiae. Ut tamen communiter de cognitione futurorum loquamur, sciendum est quod futura dupliciter cognosci possunt, uno modo, in seipsis; alio modo, in suis causis. In seipsis quidem futura cognosci non possunt nisi a Deo; cui etiam sunt praesentia dum in cursu rerum sunt futura, inquantum eius aeternus intuitus simul fertur supra totum temporis cursum, ut supra dictum est cum de Dei scientia ageretur.

Et si quidem in suis causis sint ut ex quibus ex necessitate proveniant, cognoscuntur per certitudinem scientiae; sicut astrologus praecognoscit eclipsim futuram. Si autem sic sint in suis causis ut ab eis proveniant ut in pluribus, sic cognosci possunt per quandam coniecturam vel magis vel minus certam, secundum quod causae sunt vel magis vel minus inclinatae ad effectus. ||I answer that, We must apply the same distinction to future things, as we applied above (3) to contingent things. For future things considered as subject to time are singular, and the human intellect knows them by reflection only, as stated above (1). But the principles of future things may be universal; and thus they may enter the domain of the intellect and become the objects of science. Speaking, however, of the knowledge of the future in a general way, we must observe that the future may be known in two ways: either in itself, or in its cause. The future cannot be known in itself save by God alone; to Whom even that is present which in the course of events is future, forasmuch as from eternity His glance embraces the whole course of time, as we have said above when treating of God's knowledge (14, 13). But forasmuch as it exists in its cause, the future can be known by us also. And if, indeed, the cause be such as to have a necessary connection with its future result, then the future is known with scientific certitude, just as the astronomer foresees the future eclipse. If, however, the cause be such as to produce a certain result more frequently than not, then can the future be known more or less conjecturally, according as its cause is more or less inclined to produce the effect.

||<b>IЄ q. 86 a. 4 ad 2 </b>Ad secundum dicendum quod, sicut Augustinus dicit XII Confess., anima habet quandam vim sortis, ut ex sui natura possit futura cognoscere, et ideo quando retrahitur a corporeis sensibus, et quodammodo revertitur ad seipsam, fit particeps notitiae futurorum. Et haec quidem opinio rationabilis esset, si poneremus quod anima acciperet cognitionem rerum secundum participationem idearum, sicut Platonici posuerunt, quia sic anima ex sui natura cognosceret universales causas omnium effectuum, sed impeditur per corpus; unde quando a corporis sensibus abstrahitur, futura cognoscit. Sed quia iste modus cognoscendi non est connaturalis intellectui nostro, sed magis ut cognitionem a sensibus accipiat; ideo non est secundum naturam animae quod futura cognoscat cum a sensibus alienatur; sed magis per impressionem aliquarum causarum superiorum spiritualium et corporalium. Spiritualium quidem, sicut cum virtute divina ministerio Angelorum intellectus humanus illuminatur, et phantasmata ordinantur ad futura aliqua cognoscenda; vel etiam cum per operationem Daemonum fit aliqua commotio in phantasia ad praesignandum aliqua futura quae Daemones cognoscunt, ut supra dictum est. Huiusmodi autem impressiones spiritualium causarum magis nata est anima humana suscipere cum a sensibus alienatur, quia per hoc propinquior fit substantiis spiritualibus, et magis libera ab exterioribus inquietudinibus. Contingit autem et hoc per impressionem superiorum causarum corporalium. Manifestum est enim quod corpora superiora imprimunt in corpora inferiora. Unde cum vires sensitivae sint actus corporalium organorum, consequens est quod ex impressione caelestium corporum immutetur quodammodo phantasia. Unde cum caelestia corpora sint causa multorum futurorum, fiunt in imaginatione aliqua signa quorundam futurorum. Haec autem signa magis percipiuntur in nocte et a dormientibus, quam de die et a vigilantibus, quia, ut dicitur in libro de Somn. et Vigil., quae deferuntur de die, dissolvuntur magis; plus est enim sine turbatione aer noctis, eo quod silentiores sunt noctes. Et in corpore faciunt sensum propter somnum, quia parvi motus interiores magis sentiuntur a dormientibus quam a vigilantibus. Hi vero motus faciunt phantasmata, ex quibus praevidentur futura. ||Reply to Objection 2. As Augustine says (Confess. xii [Gen. ad lit. xii. 13), the soul has a certain power of forecasting, so that by its very nature it can know the future; hence when withdrawn from corporeal sense, and, as it were, concentrated on itself, it shares in the knowledge of the future. Such an opinion would be reasonable if we were to admit that the soul receives knowledge by participating the ideas as the Platonists maintained, because in that case the soul by its nature would know the universal causes of all effects, and would only be impeded in its knowledge by the body, and hence when withdrawn from the corporeal senses it would know the future. But since it is connatural to our intellect to know things, not thus, but by receiving its knowledge from the senses; it is not natural for the soul to know the future when withdrawn from the senses: rather does it know the future by the impression of superior spiritual and corporeal causes; of spiritual causes, when by Divine power the human intellect is enlightened through the ministry of angels, and the phantasms are directed to the knowledge of future events; or, by the influence of demons, when the imagination is moved regarding the future known to the demons, as explained above (57, 3). The soul is naturally more inclined to receive these impressions of spiritual causes when it is withdrawn from the senses, as it is then nearer to the spiritual world, and freer from external distractions. The same may also come from superior corporeal causes. For it is clear that superior bodies influence inferior bodies. Hence, in consequence of the sensitive faculties being acts of corporeal organs, the influence of the heavenly bodies causes the imagination to be affected, and so, as the heavenly bodies cause many future events, the imagination receives certain images of some such events. These images are perceived more at night and while we sleep than in the daytime and while we are awake, because, as stated in De Somn. et Vigil. ii [De Divinat. per somn. ii.], "impressions made by day are evanescent. The night air is calmer, when silence reigns, hence bodily impressions are made in sleep, when slight internal movements are felt more than in wakefulness, and such movements produce in the imagination images from which the future may be foreseen."

||<b>IЄ q. 86 a. 4 ad 3 </b>Ad tertium dicendum quod animalia bruta non habent aliquid supra phantasiam quod ordinet phantasmata, sicut habent homines rationem; et ideo phantasia brutorum animalium totaliter sequitur impressionem caelestem. Et ideo ex motibus huiusmodi animalium magis possunt cognosci quaedam futura, ut pluvia et huiusmodi, quam ex motibus hominum, qui moventur per consilium rationis. Unde philosophus dicit, in libro de Somn. et Vigil., quod quidam imprudentissimi sunt maxime praevidentes, nam intelligentia horum non est curis affecta, sed tanquam deserta et vacua ab omnibus, et mota secundum movens ducitur. ||Reply to Objection 3. Brute animals have no power above the imagination wherewith to regulate it, as man has his reason, and therefore their imagination follows entirely the influence of the heavenly bodies. Thus from such animals' movements some future things, such as rain and the like, may be known rather from human movements directed by reason. Hence the Philosopher says (De Somn. et Vig.), that "some who are most imprudent are most far-seeing; for their intelligence is not burdened with cares, but is as it were barren and bare of all anxiety moving at the caprice of whatever is brought to bear on it."
