-||<b>Iª q. 75 pr. </b>Post considerationem creaturae spiritualis et corporalis, considerandum est de homine, qui ex spirituali et corporali substantia componitur. Et primo, de natura ipsius hominis; secundo, de eius productione. Naturam autem hominis considerare pertinet ad theologum ex parte animae, non autem ex parte corporis, nisi secundum habitudinem quam habet corpus ad animam. Et ideo prima consideratio circa animam versabitur. Et quia, secundum Dionysium, XI cap. Angel. Hier., tria inveniuntur in substantiis spiritualibus, scilicet essentia, virtus et operatio; primo considerabimus ea quae pertinent ad essentiam animae; secundo, ea quae pertinent ad virtutem sive potentias eius; tertio, ea quae pertinent ad operationem eius. Circa primum duplex occurrit consideratio, quarum prima est de ipsa anima secundum se; secunda, de unione eius ad corpus. Circa primum quaeruntur septem. Primo, utrum anima sit corpus. Secundo, utrum anima humana sit aliquid subsistens. Tertio, utrum animae brutorum sint subsistentes. Quarto, utrum anima sit homo; vel magis homo sit aliquid compositum ex anima et corpore. Quinto, utrum sit composita ex materia et forma. Sexto, utrum anima humana sit incorruptibilis. Septimo, utrum anima sit eiusdem speciei cum Angelo.||||

-||<div id="q75a1"><b>Iª q. 75 a. 1 arg. 1 </b>Ad primum sic proceditur. Videtur quod anima sit corpus. Anima enim est motor corporis. Non autem est movens non motum. Tum quia videtur quod nihil possit movere nisi moveatur, quia nihil dat alteri quod non habet, sicut quod non est calidum non calefacit. Tum quia, si aliquid est movens non motum, causat motum sempiternum et eodem modo se habentem, ut probatur in VIII Physic., quod non apparet in motu animalis, qui est ab anima. Ergo anima est movens motum. Sed omne movens motum est corpus. Ergo anima est corpus.||Objection 1. It would seem that the soul is a body. For the soul is the moving principle of the body. Nor does it move unless moved. First, because seemingly nothing can move unless it is itself moved, since nothing gives what it has not; for instance, what is not hot does not give heat. Secondly, because if there be anything that moves and is not moved, it must be the cause of eternal, unchanging movement, as we find proved Phys. viii, 6; and this does not appear to be the case in the movement of an animal, which is caused by the soul. Therefore the soul is a mover moved. But every mover moved is a body. Therefore the soul is a body. ||

-||<b>Iª q. 75 a. 1 arg. 2 </b>Praeterea, omnis cognitio fit per aliquam similitudinem. Non potest autem esse similitudo corporis ad rem incorpoream. Si igitur anima non esset corpus, non posset cognoscere res corporeas.||Objection 2. Further, all knowledge is caused by means of a likeness. But there can be no likeness of a body to an incorporeal thing. If, therefore, the soul were not a body, it could not have knowledge of corporeal things. ||

-||<b>Iª q. 75 a. 1 arg. 3 </b>Praeterea, moventis ad motum oportet esse aliquem contactum. Contactus autem non est nisi corporum. Cum igitur anima moveat corpus, videtur quod anima sit corpus.||Objection 3. Further, between the mover and the moved there must be contact. But contact is only between bodies. Since, therefore, the soul moves the body, it seems that the soul must be a body. ||

-||<b>Iª q. 75 a. 1 s. c. </b>Sed contra est quod Augustinus dicit, VI de Trin., quod anima simplex dicitur respectu corporis, quia mole non diffunditur per spatium loci.||On the contrary, Augustine says (De Trin. vi, 6) that the soul "is simple in comparison with the body, inasmuch as it does not occupy space by its bulk." ||

-||<b>Iª q. 75 a. 1 co. </b>Respondeo dicendum quod ad inquirendum de natura animae, oportet praesupponere quod anima dicitur esse primum principium vitae in his quae apud nos vivunt animata enim viventia dicimus, res vero inanimatas vita carentes. Vita autem maxime manifestatur duplici opere, scilicet cognitionis et motus. Horum autem principium antiqui philosophi, imaginationem transcendere non valentes, aliquod corpus ponebant; sola corpora res esse dicentes, et quod non est corpus, nihil esse. Et secundum hoc, animam aliquod corpus esse dicebant. Huius autem opinionis falsitas licet multipliciter ostendi possit tamen uno utemur, quo et communius et certius patet animam corpus non esse. Manifestum est enim quod non quodcumque vitalis operationis principium est anima, sic enim oculus esset anima, cum sit quoddam principium visionis; et idem esset dicendum de aliis animae instrumentis. Sed primum principium vitae dicimus esse animam. Quamvis autem aliquod corpus possit esse quoddam principium vitae, sicut cor est principium vitae in animali; tamen non potest esse primum principium vitae aliquod corpus. Manifestum est enim quod esse principium vitae, vel vivens, non convenit corpori ex hoc quod est corpus, alioquin omne corpus esset vivens, aut principium vitae. Convenit igitur alicui corpori quod sit vivens, vel etiam principium vitae, per hoc quod est tale corpus. Quod autem est actu tale, habet hoc ab aliquo principio quod dicitur actus eius. Anima igitur, quae est primum principium vitae, non est corpus, sed corporis actus, sicut calor, qui est principium calefactionis, non est corpus, sed quidam corporis actus.||I answer that, To seek the nature of the soul, we must premise that the soul is defined as the first principle of life of those things which live: for we call living things "animate," [i.e. having a soul], and those things which have no life, "inanimate." Now life is shown principally by two actions, knowledge and movement. The philosophers of old, not being able to rise above their imagination, supposed that the principle of these actions was something corporeal: for they asserted that only bodies were real things; and that what is not corporeal is nothing: hence they maintained that the soul is something corporeal. This opinion can be proved to be false in many ways; but we shall make use of only one proof, based on universal and certain principles, which shows clearly that the soul is not a body. It is manifest that not every principle of vital action is a soul, for then the eye would be a soul, as it is a principle of vision; and the same might be applied to the other instruments of the soul: but it is the "first" principle of life, which we call the soul. Now, though a body may be a principle of life, or to be a living thing, as the heart is a principle of life in an animal, yet nothing corporeal can be the first principle of life. For it is clear that to be a principle of life, or to be a living thing, does not belong to a body as such; since, if that were the case, every body would be a living thing, or a principle of life. Therefore a body is competent to be a living thing or even a principle of life, as "such" a body. Now that it is actually such a body, it owes to some principle which is called its act. Therefore the soul, which is the first principle of life, is not a body, but the act of a body; thus heat, which is the principle of calefaction, is not a body, but an act of a body. ||

-||<b>Iª q. 75 a. 1 ad 1 </b>Ad primum ergo dicendum quod, cum omne quod movetur ab alio moveatur, quod non potest in infinitum procedere, necesse est dicere quod non omne movens movetur. Cum enim moveri sit exire de potentia in actum, movens dat id quod habet mobili, inquantum facit ipsum esse in actu. Sed sicut ostenditur in VIII Physic., est quoddam movens penitus immobile, quod nec per se nec per accidens movetur, et tale movens potest movere motum semper uniformem. Est autem aliud movens, quod non movetur per se, sed movetur per accidens, et propter hoc non movet motum semper uniformem. Et tale movens est anima. Est autem aliud movens, quod per se movetur, scilicet corpus. Et quia antiqui naturales nihil esse credebant nisi corpora, posuerunt quod omne movens movetur, et quod anima per se movetur, et est corpus.||Reply to Objection 1. As everything which is in motion must be moved by something else, a process which cannot be prolonged indefinitely, we must allow that not every mover is moved. For, since to be moved is to pass from potentiality to actuality, the mover gives what it has to the thing moved, inasmuch as it causes it to be in act. But, as is shown in Phys. viii, 6, there is a mover which is altogether immovable, and not moved either essentially, or accidentally; and such a mover can cause an invariable movement. There is, however, another kind of mover, which, though not moved essentially, is moved accidentally; and for this reason it does not cause an invariable movement; such a mover, is the soul. There is, again, another mover, which is moved essentially--namely, the body. And because the philosophers of old believed that nothing existed but bodies, they maintained that every mover is moved; and that the soul is moved directly, and is a body. ||

-||<b>Iª q. 75 a. 1 ad 2 </b>Ad secundum dicendum quod non est necessarium quod similitudo rei cognitae sit actu in natura cognoscentis, sed si aliquid sit quod prius est cognoscens in potentia et postea in actu, oportet quod similitudo cogniti non sit actu in natura cognoscentis, sed in potentia tantum; sicut color non est actu in pupilla, sed in potentia tantum. Unde non oportet quod in natura animae sit similitudo rerum corporearum in actu; sed quod sit in potentia ad huiusmodi similitudines. Sed quia antiqui naturales nesciebant distinguere inter actum et potentiam, ponebant animam esse corpus, ad hoc quod cognosceret corpus; et ad hoc quod cognosceret omnia corpora, quod esset composita ex principiis omnium corporum.||Reply to Objection 2. The likeness of a thing known is not of necessity actually in the nature of the knower; but given a thing which knows potentially, and afterwards knows actually, the likeness of the thing known must be in the nature of the knower, not actually, but only potentially; thus color is not actually in the pupil of the eye, but only potentially. Hence it is necessary, not that the likeness of corporeal things should be actually in the nature of the soul, but that there be a potentiality in the soul for such a likeness. But the ancient philosophers omitted to distinguish between actuality and potentiality; and so they held that the soul must be a body in order to have knowledge of a body; and that it must be composed of the principles of which all bodies are formed in order to know all bodies. ||

-||<b>Iª q. 75 a. 1 ad 3 </b>Ad tertium dicendum quod est duplex contactus, quantitatis et virtutis. Primo modo, corpus non tangitur nisi a corpore. Secundo modo, corpus potest tangi a re incorporea quae movet corpus.||Reply to Objection 3. There are two kinds of contact; of "quantity," and of "power." By the former a body can be touched only by a body; by the latter a body can be touched by an incorporeal thing, which moves that body. ||

-||<div id="q75a2"><b>Iª q. 75 a. 2 arg. 1 </b>Ad secundum sic proceditur. Videtur quod anima humana non sit aliquid subsistens. Quod enim est subsistens, dicitur hoc aliquid. Anima autem non est hoc aliquid, sed compositum ex anima et corpore. Ergo anima non est aliquid subsistens.||Objection 1. It would seem that the human soul is not something subsistent. For that which subsists is said to be "this particular thing." Now "this particular thing" is said not of the soul, but of that which is composed of soul and body. Therefore the soul is not something subsistent. ||
-|- valign = top
-||<b>Iª q. 75 a. 2 arg. 2 </b>Praeterea, omne quod est subsistens, potest dici operari. Sed anima non dicitur operari, quia, ut dicitur in I de anima, dicere animam sentire aut intelligere, simile est ac si dicat eam aliquis texere vel aedificare. Ergo anima non est aliquid subsistens.||Objection 2. Further, everything subsistent operates. But the soul does not operate; for, as the Philosopher says (De Anima i, 4), "to say that the soul feels or understands is like saying that the soul weaves or builds." Therefore the soul is not subsistent. ||
-|- valign = top
-||<b>Iª q. 75 a. 2 arg. 3 </b>Praeterea, si anima esset aliquid subsistens, esset aliqua eius operatio sine corpore. Sed nulla est eius operatio sine corpore, nec etiam intelligere, quia non contingit intelligere sine phantasmate, phantasma autem non est sine corpore. Ergo anima humana non est aliquid subsistens.||Objection 3. Further, if the soul were subsistent, it would have some operation apart from the body. But it has no operation apart from the body, not even that of understanding: for the act of understanding does not take place without a phantasm, which cannot exist apart from the body. Therefore the human soul is not something subsistent. ||

-||<b>Iª q. 75 a. 2 s. c. </b>Sed contra est quod Augustinus dicit, X de Trin. Quisquis videt mentis naturam et esse substantiam, et non esse corpoream, videt eos qui opinantur eam esse corpoream, ob hoc errare, quod adiungunt ei ea sine quibus nullam possunt cogitare naturam, scilicet corporum phantasias. Natura ergo mentis humanae non solum est incorporea, sed etiam substantia, scilicet aliquid subsistens.||On the contrary, Augustine says (De Trin. x, 7): "Who understands that the nature of the soul is that of a substance and not that of a body, will see that those who maintain the corporeal nature of the soul, are led astray through associating with the soul those things without which they are unable to think of any nature--i.e. imaginary pictures of corporeal things." Therefore the nature of the human intellect is not only incorporeal, but it is also a substance, that is, something subsistent. ||

-||<b>Iª q. 75 a. 2 co. </b>Respondeo dicendum quod necesse est dicere id quod est principium intellectualis operationis, quod dicimus animam hominis, esse quoddam principium incorporeum et subsistens. Manifestum est enim quod homo per intellectum cognoscere potest naturas omnium corporum. Quod autem potest cognoscere aliqua, oportet ut nihil eorum habeat in sua natura, quia illud quod inesset ei naturaliter impediret cognitionem aliorum; sicut videmus quod lingua infirmi quae infecta est cholerico et amaro humore, non potest percipere aliquid dulce, sed omnia videntur ei amara. Si igitur principium intellectuale haberet in se naturam alicuius corporis, non posset omnia corpora cognoscere. Omne autem corpus habet aliquam naturam determinatam. Impossibile est igitur quod principium intellectuale sit corpus. Et similiter impossibile est quod intelligat per organum corporeum, quia etiam natura determinata illius organi corporei prohiberet cognitionem omnium corporum; sicut si aliquis determinatus color sit non solum in pupilla, sed etiam in vase vitreo, liquor infusus eiusdem coloris videtur. Ipsum igitur intellectuale principium, quod dicitur mens vel intellectus, habet operationem per se, cui non communicat corpus. Nihil autem potest per se operari, nisi quod per se subsistit. Non enim est operari nisi entis in actu, unde eo modo aliquid operatur, quo est. Propter quod non dicimus quod calor calefacit, sed calidum. Relinquitur igitur animam humanam, quae dicitur intellectus vel mens, esse aliquid incorporeum et subsistens.||I answer that, It must necessarily be allowed that the principle of intellectual operation which we call the soul, is a principle both incorporeal and subsistent. For it is clear that by means of the intellect man can have knowledge of all corporeal things. Now whatever knows certain things cannot have any of them in its own nature; because that which is in it naturally would impede the knowledge of anything else. Thus we observe that a sick man's tongue being vitiated by a feverish and bitter humor, is insensible to anything sweet, and everything seems bitter to it. Therefore, if the intellectual principle contained the nature of a body it would be unable to know all bodies. Now every body has its own determinate nature. Therefore it is impossible for the intellectual principle to be a body. It is likewise impossible for it to understand by means of a bodily organ; since the determinate nature of that organ would impede knowledge of all bodies; as when a certain determinate color is not only in the pupil of the eye, but also in a glass vase, the liquid in the vase seems to be of that same color. Therefore the intellectual principle which we call the mind or the intellect has an operation "per se" apart from the body. Now only that which subsists can have an operation "per se." For nothing can operate but what is actual: for which reason we do not say that heat imparts heat, but that what is hot gives heat. We must conclude, therefore, that the human soul, which is called the intellect or the mind, is something incorporeal and subsistent. ||

-||<b>Iª q. 75 a. 2 ad 1 </b>Ad primum ergo dicendum quod hoc aliquid potest accipi dupliciter, uno modo, pro quocumque subsistente, alio modo, pro subsistente completo in natura alicuius speciei. Primo modo, excludit inhaerentiam accidentis et formae materialis, secundo modo, excludit etiam imperfectionem partis. Unde manus posset dici hoc aliquid primo modo, sed non secundo modo. Sic igitur, cum anima humana sit pars speciei humanae, potest dici hoc aliquid primo modo, quasi subsistens, sed non secundo modo, sic enim compositum ex anima et corpore dicitur hoc aliquid.||Reply to Objection 1. "This particular thing" can be taken in two senses. Firstly, for anything subsistent; secondly, for that which subsists, and is complete in a specific nature. The former sense excludes the inherence of an accident or of a material form; the latter excludes also the imperfection of the part, so that a hand can be called "this particular thing" in the first sense, but not in the second. Therefore, as the human soul is a part of human nature, it can indeed be called "this particular thing," in the first sense, as being something subsistent; but not in the second, for in this sense, what is composed of body and soul is said to be "this particular thing." ||

-||<b>Iª q. 75 a. 2 ad 2 </b>Ad secundum dicendum quod verba illa Aristoteles dicit non secundum propriam sententiam, sed secundum opinionem illorum qui dicebant quod intelligere est moveri; ut patet ex iis quae ibi praemittit. Vel dicendum quod per se agere convenit per se existenti. Sed per se existens quandoque potest dici aliquid si non sit inhaerens ut accidens vel ut forma materialis, etiam si sit pars. Sed proprie et per se subsistens dicitur quod neque est praedicto modo inhaerens, neque est pars. Secundum quem modum oculus aut manus non posset dici per se subsistens; et per consequens nec per se operans. Unde et operationes partium attribuuntur toti per partes. Dicimus enim quod homo videt per oculum, et palpat per manum, aliter quam calidum calefacit per calorem, quia calor nullo modo calefacit, proprie loquendo. Potest igitur dici quod anima intelligit, sicut oculus videt, sed magis proprie dicitur quod homo intelligat per animam.||Reply to Objection 2. Aristotle wrote those words as expressing not his own opinion, but the opinion of those who said that to understand is to be moved, as is clear from the context. Or we may reply that to operate "per se" belongs to what exists "per se." But for a thing to exist "per se," it suffices sometimes that it be not inherent, as an accident or a material form; even though it be part of something. Nevertheless, that is rightly said to subsist "per se," which is neither inherent in the above sense, nor part of anything else. In this sense, the eye or the hand cannot be said to subsist "per se"; nor can it for that reason be said to operate "per se." Hence the operation of the parts is through each part attributed to the whole. For we say that man sees with the eye, and feels with the hand, and not in the same sense as when we say that what is hot gives heat by its heat; for heat, strictly speaking, does not give heat. We may therefore say that the soul understands, as the eye sees; but it is more correct to say that man understands through the soul. ||

-||<b>Iª q. 75 a. 2 ad 3 </b>Ad tertium dicendum quod corpus requiritur ad actionem intellectus, non sicut organum quo talis actio exerceatur, sed ratione obiecti, phantasma enim comparatur ad intellectum sicut color ad visum. Sic autem indigere corpore non removet intellectum esse subsistentem, alioquin animal non esset aliquid subsistens, cum indigeat exterioribus sensibilibus ad sentiendum.||Reply to Objection 3. The body is necessary for the action of the intellect, not as its origin of action, but on the part of the object; for the phantasm is to the intellect what color is to the sight. Neither does such a dependence on the body prove the intellect to be non-subsistent; otherwise it would follow that an animal is non-subsistent, since it requires external objects of the senses in order to perform its act of perception. ||

-||<div id="q75a3"><b>Iª q. 75 a. 3 arg. 1 </b>Ad tertium sic proceditur. Videtur quod animae brutorum animalium sint subsistentes. Homo enim convenit in genere cum aliis animalibus. Sed anima hominis est aliquid subsistens, ut ostensum est. Ergo et animae aliorum animalium sunt subsistentes.||Objection 1. It would seem that the souls of brute animals are subsistent. For man is of the same 'genus' as other animals; and, as we have just shown (2), the soul of man is subsistent. Therefore the souls of other animals are subsistent. ||
-|- valign = top
-||<b>Iª q. 75 a. 3 arg. 2 </b>Praeterea, similiter se habet sensitivum ad sensibilia, sicut intellectivum et intelligibilia. Sed intellectus intelligit intelligibilia sine corpore. Ergo et sensus apprehendit sensibilia sine corpore. Animae autem brutorum animalium sunt sensitivae. Ergo sunt subsistentes, pari ratione qua et anima hominis, quae est intellectiva.||Objection 2. Further, the relation of the sensitive faculty to sensible objects is like the relation of the intellectual faculty to intelligible objects. But the intellect, apart from the body, apprehends intelligible objects. Therefore the sensitive faculty, apart from the body, perceives sensible objects. Therefore, since the souls of brute animals are sensitive, it follows that they are subsistent; just as the human intellectual soul is subsistent. ||

-||<b>Iª q. 75 a. 3 arg. 3 </b>Praeterea, brutorum animalium anima movet corpus. Corpus autem non movet, sed movetur. Anima ergo bruti animalis habet aliquam operationem sine corpore.||Objection 3. Further, the soul of brute animals moves the body. But the body is not a mover, but is moved. Therefore the soul of brute animals has an operation apart from the body. ||

-||<b>Iª q. 75 a. 3 s. c. </b>Sed contra est quod dicitur in libro de Eccl. Dogmat., solum hominem credimus habere animam substantivam; animalium vero animae non sunt substantivae.||On the contrary, Is what is written in the book De Eccl. Dogm. xvi, xvii: "Man alone we believe to have a subsistent soul: whereas the souls of animals are not subsistent." ||
-|- valign = top
-||<b>Iª q. 75 a. 3 co. </b>Respondeo dicendum quod antiqui philosophi nullam distinctionem ponebant inter sensum et intellectum, et utrumque corporeo principio attribuebant, ut dictum est. Plato autem distinxit inter intellectum et sensum; utrumque tamen attribuit principio incorporeo, ponens quod, sicut intelligere, ita et sentire convenit animae secundum seipsam. Et ex hoc sequebatur quod etiam animae brutorum animalium sint subsistentes. Sed Aristoteles posuit quod solum intelligere, inter opera animae, sine organo corporeo exercetur. Sentire vero, et consequentes operationes animae sensitivae, manifeste accidunt cum aliqua corporis immutatione; sicut in videndo immutatur pupilla per speciem coloris; et idem apparet in aliis. Et sic manifestum est quod anima sensitiva non habet aliquam operationem propriam per seipsam, sed omnis operatio sensitivae animae est coniuncti. Ex quo relinquitur quod, cum animae brutorum animalium per se non operentur, non sint subsistentes, similiter enim unumquodque habet esse et operationem.||I answer that, The ancient philosophers made no distinction between sense and intellect, and referred both a corporeal principle, as has been said (1). Plato, however, drew a distinction between intellect and sense; yet he referred both to an incorporeal principle, maintaining that sensing, just as understanding, belongs to the soul as such. From this it follows that even the souls of brute animals are subsistent. But Aristotle held that of the operations of the soul, understanding alone is performed without a corporeal organ. On the other hand, sensation and the consequent operations of the sensitive soul are evidently accompanied with change in the body; thus in the act of vision, the pupil of the eye is affected by a reflection of color: and so with the other senses. Hence it is clear that the sensitive soul has no "per se" operation of its own, and that every operation of the sensitive soul belongs to the composite. Wherefore we conclude that as the souls of brute animals have no "per se" operations they are not subsistent. For the operation of anything follows the mode of its being. ||

Nec oportet quod omnis differentia formae faciat generis diversitatem.||Reply to Objection 1. Although man is of the same "genus" as other animals, he is of a different "species." Specific difference is derived from the difference of form; nor does every difference of form necessarily imply a diversity of "genus." ||

-||<b>Iª q. 75 a. 3 ad 2 </b>Ad secundum dicendum quod sensitivum quodammodo se habet ad sensibilia sicut intellectivum ad intelligibilia, inquantum scilicet utrumque est in potentia ad sua obiecta. Sed quodammodo dissimiliter se habent, inquantum sensitivum patitur a sensibili cum corporis immutatione, unde excellentia sensibilium corrumpit sensum. Quod in intellectu non contingit, nam intellectus intelligens maxima intelligibilium, magis potest postmodum intelligere minora. Si vero in intelligendo fatigetur corpus, hoc est per accidens, in quantum intellectus indiget operatione virium sensitivarum, per quas ei phantasmata praeparantur.||Reply to Objection 2. The relation of the sensitive faculty to the sensible object is in one way the same as that of the intellectual faculty to the intelligible object, in so far as each is in potentiality to its object. But in another way their relations differ, inasmuch as the impression of the object on the sense is accompanied with change in the body; so that excessive strength of the sensible corrupts sense; a thing that never occurs in the case of the intellect. For an intellect that understands the highest of intelligible objects is more able afterwards to understand those that are lower. If, however, in the process of intellectual operation the body is weary, this result is accidental, inasmuch as the intellect requires the operation of the sensitive powers in the production of the phantasms. ||

-||<b>Iª q. 75 a. 3 ad 3 </b>Ad tertium dicendum quod vis motiva est duplex. Una quae imperat motum, scilicet appetitiva. Et huius operatio in anima sensitiva non est sine corpore; sed ira et gaudium et omnes huiusmodi passiones sunt cum aliqua corporis immutatione. Alia vis motiva est exequens motum, per quam membra redduntur habilia ad obediendum appetitui, cuius actus non est movere, sed moveri. Unde patet quod movere non est actus animae sensitivae sine corpore.||Reply to Objection 3. Motive power is of two kinds. One, the appetitive power, commands motion. The operation of this power in the sensitive soul is not apart from the body; for anger, joy, and passions of a like nature are accompanied by a change in the body. The other motive power is that which executes motion in adapting the members for obeying the appetite; and the act of this power does not consist in moving, but in being moved. Whence it is clear that to move is not an act of the sensitive soul without the body. ||

It would seem that the soul is man. For it is written (2 Corinthians 4:16): "Though our outward man is corrupted, yet the inward man is renewed day by day." But that which is within man is the soul.

Therefore it is a particular substance. Therefore it is a "hypostasis" or a person; and it can only be a human person. Therefore the soul is man; for a human person is a man. ||

-||<b>Iª q. 75 a. 4 co. </b>Respondeo dicendum quod animam esse hominem dupliciter potest intelligi. Uno modo, quod homo sit anima, sed hic homo non sit anima, sed compositum ex anima et corpore, puta Socrates. Quod ideo dico, quia quidam posuerunt solam formam esse de ratione speciei, materiam vero esse partem individui, et non speciei. Quod quidem non potest esse verum. Nam ad naturam speciei pertinet id quod significat definitio. Definitio autem in rebus naturalibus non significat formam tantum, sed formam et materiam. Unde materia est pars speciei in rebus naturalibus, non quidem materia signata, quae est principium individuationis; sed materia communis. Sicut enim de ratione huius hominis est quod sit ex hac anima et his carnibus et his ossibus; ita de ratione hominis est quod sit ex anima et carnibus et ossibus. Oportet enim de substantia speciei esse quidquid est communiter de substantia omnium individuorum sub specie contentorum. Alio vero modo potest intelligi sic, quod etiam haec anima sit hic homo. Et hoc quidem sustineri posset, si poneretur quod animae sensitivae operatio esset eius propria sine corpore, quia omnes operationes quae attribuuntur homini, convenirent soli animae; illud autem est unaquaeque res, quod operatur operationes illius rei. Unde illud est homo, quod operatur operationes hominis. Ostensum est autem quod sentire non est operatio animae tantum. Cum igitur sentire sit quaedam operatio hominis, licet non propria, manifestum est quod homo non est anima tantum, sed est aliquid compositum ex anima et corpore. Plato vero, ponens sentire esse proprium animae, ponere potuit quod homo esset anima utens corpore.||I answer that, The assertion "the soul is man," can be taken in two senses. First, that man is a soul; though this particular man, Socrates, for instance, is not a soul, but composed of soul and body. I say this, forasmuch as some held that the form alone belongs to the species; while matter is part of the individual, and not the species. This cannot be true; for to the nature of the species belongs what the definition signifies; and in natural things the definition does not signify the form only, but the form and the matter. Hence in natural things the matter is part of the species; not, indeed, signate matter, which is the principle of individuality; but the common matter. For as it belongs to the notion of this particular man to be composed of this soul, of this flesh, and of these bones; so it belongs to the notion of man to be composed of soul, flesh, and bones; for whatever belongs in common to the substance of all the individuals contained under a given species, must belong to the substance of the species. It may also be understood in this sense, that this soul is this man; and this could be held if it were supposed that the operation of the sensitive soul were proper to it, apart from the body; because in that case all the operations which are attributed to man would belong to the soul only; and whatever performs the operations proper to a thing, is that thing; wherefore that which performs the operations of a man is man. But it has been shown above (3) that sensation is not the operation of the soul only. Since, then, sensation is an operation of man, but not proper to him, it is clear that man is not a soul only, but something composed of soul and body. Plato, through supposing that sensation was proper to the soul, could maintain man to be a soul making use of the body. ||

In this way sometimes what is principle in man is said to be man; sometimes, indeed, the intellectual part which, in accordance with truth, is called the "inward" man; and sometimes the sensitive part with the body is called man in the opinion of those whose observation does not go beyond the senses.

It would seem that the soul is composed of matter and form. For potentiality is opposed to actuality. Now, whatsoever things are in actuality participate of the First Act, which is God; by participation of Whom, all things are good, are beings, and are living things, as is clear from the teaching of Dionysius (Div. Nom. v). Therefore whatsoever things are in potentiality participate of the first potentiality. But the first potentiality is primary matter. Therefore, since the human soul is, after a manner, in potentiality; which appears from the fact that sometimes a man is potentially understanding; it seems that the human soul must participate of primary matter, as part of itself. ||

-||<b>Iª q. 75 a. 5 co. </b>Respondeo dicendum quod anima non habet materiam. Et hoc potest considerari dupliciter. Primo quidem, ex ratione animae in communi. Est enim de ratione animae, quod sit forma alicuius corporis. Aut igitur est forma secundum se totam; aut secundum aliquam partem sui. Si secundum se totam, impossibile est quod pars eius sit materia, si dicatur materia aliquod ens in potentia tantum, quia forma, inquantum forma, est actus; id autem quod est in potentia tantum, non potest esse pars actus, cum potentia repugnet actui, utpote contra actum divisa. Si autem sit forma secundum aliquam partem sui, illam partem, dicemus esse animam, et illam materiam cuius primo est actus, dicemus esse primum animatum. Secundo, specialiter ex ratione humanae animae, inquantum est intellectiva. Manifestum est enim quod omne quod recipitur in aliquo, recipitur in eo per modum recipientis. Sic autem cognoscitur unumquodque, sicut forma eius est in cognoscente anima autem intellectiva cognoscit rem aliquam in sua natura absolute, puta lapidem inquantum est lapis absolute. Est igitur forma lapidis absolute, secundum propriam rationem formalem, in anima intellectiva. Anima igitur intellectiva est forma absoluta, non autem aliquid compositum ex materia et forma. Si enim anima intellectiva esset composita ex materia et forma, formae rerum reciperentur in ea ut individuales, et sic non cognosceret nisi singulare, sicut accidit in potentiis sensitivis, quae recipiunt formas rerum in organo corporali, materia enim est principium individuationis formarum. Relinquitur ergo quod anima intellectiva, et omnis intellectualis substantia cognoscens formas absolute, caret compositione formae et materiae.||I answer that, The soul has no matter. We may consider this question in two ways. First, from the notion of a soul in general; for it belongs to the notion of a soul to be the form of a body. Now, either it is a form by virtue of itself, in its entirety, or by virtue of some part of itself. If by virtue of itself in its entirety, then it is impossible that any part of it should be matter, if by matter we understand something purely potential: for a form, as such, is an act; and that which is purely potentiality cannot be part of an act, since potentiality is repugnant to actuality as being opposite thereto. If, however, it be a form by virtue of a part of itself, then we call that part the soul: and that matter, which it actualizes first, we call the "primary animate." Secondly, we may proceed from the specific notion of the human soul inasmuch as it is intellectual. For it is clear that whatever is received into something is received according to the condition of the recipient. Now a thing is known in as far as its form is in the knower. But the intellectual soul knows a thing in its nature absolutely: for instance, it knows a stone absolutely as a stone; and therefore the form of a stone absolutely, as to its proper formal idea, is in the intellectual soul. Therefore the intellectual soul itself is an absolute form, and not something composed of matter and form. For if the intellectual soul were composed of matter and form, the forms of things would be received into it as individuals, and so it would only know the individual: just as it happens with the sensitive powers which receive forms in a corporeal organ; since matter is the principle by which forms are individualized. It follows, therefore, that the intellectual soul, and every intellectual substance which has knowledge of forms absolutely, is exempt from composition of matter and form. ||

Unde participatur a rebus, non sicut pars, sed secundum diffusionem processionis ipsius. Potentia autem, cum sit receptiva actus, oportet quod actui proportionetur. Actus vero recepti, qui procedunt a primo actu infinito et sunt quaedam participationes eius, sunt diversi. Unde non potest esse potentia una quae recipiat omnes actus, sicut est unus actus influens omnes actus participatos, alioquin potentia receptiva adaequaret potentiam activam primi actus. Est autem alia potentia receptiva in anima intellectiva, a potentia receptiva materiae primae, ut patet ex diversitate receptorum, nam materia prima recipit formas individuales, intellectus autem recipit formas absolutas. Unde talis potentia in anima intellectiva existens, non ostendit quod anima sit composita ex materia et forma.||Reply to Objection 1. The First Act is the universal principle of all acts; because It is infinite, virtually "precontaining all things," as Dionysius says (Div. Nom. v). Wherefore things participate of It not as a part of themselves, but by diffusion of Its processions. Now as potentiality is receptive of act, it must be proportionate to act. But the acts received which proceed from the First Infinite Act, and are participations thereof, are diverse, so that there cannot be one potentiality which receives all acts, as there is one act, from which all participated acts are derived; for then the receptive potentiality would equal the active potentiality of the First Act. Now the receptive potentiality in the intellectual soul is other than the receptive potentiality of first matter, as appears from the diversity of the things received by each. For primary matter receives individual forms; whereas the intelligence receives absolute forms. Hence the existence of such a potentiality in the intellectual soul does not prove that the soul is composed of matter and form. ||

To be a subject and to be changed belong to matter by reason of its being in potentiality. As, therefore, the potentiality of the intelligence is one thing and the potentiality of primary matter another, so in each is there a different reason of subjection and change. For the intelligence is subject to knowledge, and is changed from ignorance to knowledge, by reason of its being in potentiality with regard to the intelligible species. ||

Unde post verba praemissa, philosophus concludit quod in his quae sunt composita ex materia et forma, nulla est alia causa nisi movens ex potestate ad actum, quaecumque vero non habent materiam, omnia simpliciter sunt quod vere entia aliquid.||Reply to Objection 3. The form causes matter to be, and so does the agent; wherefore the agent causes matter to be, so far as it actualizes it by transmuting it to the act of a form. A subsistent form, however, does not owe its existence to some formal principle, nor has it a cause transmuting it from potentiality to act. So after the words quoted above, the Philosopher concludes, that in things composed of matter and form "there is no other cause but that which moves from potentiality to act; while whatsoever things have no matter are simply beings at once."

Esse autem participatum finitur ad capacitatem participantis. Unde solus Deus, qui est ipsum suum esse, est actus purus et infinitus. In substantiis vero intellectualibus est compositio ex actu et potentia; non quidem ex materia et forma, sed ex forma et esse participato. Unde a quibusdam dicuntur componi ex quo est et quod est, ipsum enim esse est quo aliquid est.||Reply to Objection 4. Everything participated is compared to the participator as its act. But whatever created form be supposed to subsist "per se," must have existence by participation; for "even life," or anything of that sort, "is a participator of existence," as Dionysius says (Div. Nom. v). Now participated existence is limited by the capacity of the participator; so that God alone, Who is His own existence, is pure act and infinite. But in intellectual substances there is composition of actuality and potentiality, not, indeed, of matter and form, but of form and participated existence. Wherefore some say that they are composed of that "whereby they are" and that "which they are"; for existence itself is that by which a thing is. ||

-||<b>Iª q. 75 a. 6 co. </b>Respondeo dicendum quod necesse est dicere animam humanam, quam dicimus intellectivum principium, esse incorruptibilem. Dupliciter enim aliquid corrumpitur, uno modo, per se; alio modo, per accidens. Impossibile est autem aliquid subsistens generari aut corrumpi per accidens, idest aliquo generato vel corrupto. Sic enim competit alicui generari et corrumpi, sicut et esse, quod per generationem acquiritur et per corruptionem amittitur. Unde quod per se habet esse, non potest generari vel corrumpi nisi per se, quae vero non subsistunt, ut accidentia et formae materiales, dicuntur fieri et corrumpi per generationem et corruptionem compositorum. Ostensum est autem supra quod animae brutorum non sunt per se subsistentes, sed sola anima humana. Unde animae brutorum corrumpuntur, corruptis corporibus, anima autem humana non posset corrumpi, nisi per se corrumperetur. Quod quidem omnino est impossibile non solum de ipsa, sed de quolibet subsistente quod est forma tantum. Manifestum est enim quod id quod secundum se convenit alicui, est inseparabile ab ipso. Esse autem per se convenit formae, quae est actus. Unde materia secundum hoc acquirit esse in actu, quod acquirit formam, secundum hoc autem accidit in ea corruptio, quod separatur forma ab ea. Impossibile est autem quod forma separetur a seipsa. Unde impossibile est quod forma subsistens desinat esse. Dato etiam quod anima esset ex materia et forma composita, ut quidam dicunt, adhuc oporteret ponere eam incorruptibilem. Non enim invenitur corruptio nisi ubi invenitur contrarietas, generationes enim et corruptiones ex contrariis et in contraria sunt; unde corpora caelestia, quia non habent materiam contrarietati subiectam, incorruptibilia sunt. In anima autem intellectiva non potest esse aliqua contrarietas. Recipit enim secundum modum sui esse, ea vero quae in ipsa recipiuntur, sunt absque contrarietate; quia etiam rationes contrariorum in intellectu non sunt contrariae, sed est una scientia contrariorum. Impossibile est ergo quod anima intellectiva sit corruptibilis. Potest etiam huius rei accipi signum ex hoc, quod unumquodque naturaliter suo modo esse desiderat. Desiderium autem in rebus cognoscentibus sequitur cognitionem. Sensus autem non cognoscit esse nisi sub hic et nunc, sed intellectus apprehendit esse absolute, et secundum omne tempus. Unde omne habens intellectum naturaliter desiderat esse semper. Naturale autem desiderium non potest esse inane. Omnis igitur intellectualis substantia est incorruptibilis.||I answer that, We must assert that the intellectual principle which we call the human soul is incorruptible. For a thing may be corrupted in two ways--"per se," and accidentally. Now it is impossible for any substance to be generated or corrupted accidentally, that is, by the generation or corruption of something else. For generation and corruption belong to a thing, just as existence belongs to it, which is acquired by generation and lost by corruption. Therefore, whatever has existence "per se" cannot be generated or corrupted except 'per se'; while things which do not subsist, such as accidents and material forms, acquire existence or lost it through the generation or corruption of composite things. Now it was shown above (2,3) that the souls of brutes are not self-subsistent, whereas the human soul is; so that the souls of brutes are corrupted, when their bodies are corrupted; while the human soul could not be corrupted unless it were corrupted "per se." This, indeed, is impossible, not only as regards the human soul, but also as regards anything subsistent that is a form alone. For it is clear that what belongs to a thing by virtue of itself is inseparable from it; but existence belongs to a form, which is an act, by virtue of itself. Wherefore matter acquires actual existence as it acquires the form; while it is corrupted so far as the form is separated from it. But it is impossible for a form to be separated from itself; and therefore it is impossible for a subsistent form to cease to exist. Granted even that the soul is composed of matter and form, as some pretend, we should nevertheless have to maintain that it is incorruptible. For corruption is found only where there is contrariety; since generation and corruption are from contraries and into contraries. Wherefore the heavenly bodies, since they have no matter subject to contrariety, are incorruptible. Now there can be no contrariety in the intellectual soul; for it receives according to the manner of its existence, and those things which it receives are without contrariety; for the notions even of contraries are not themselves contrary, since contraries belong to the same knowledge. Therefore it is impossible for the intellectual soul to be corruptible. Moreover we may take a sign of this from the fact that everything naturally aspires to existence after its own manner. Now, in things that have knowledge, desire ensues upon knowledge. The senses indeed do not know existence, except under the conditions of "here" and "now," whereas the intellect apprehends existence absolutely, and for all time; so that everything that has an intellect naturally desires always to exist. But a natural desire cannot be in vain. Therefore every intellectual substance is incorruptible. ||

Therefore the saying that man and animals have a like beginning in generation is true of the body; for all animals alike are made of earth. But it is not true of the soul. For the souls of brutes are produced by some power of the body; whereas the human soul is produced by God. To signify this it is written as to other animals: "Let the earth bring forth the living soul" (Genesis 1:24): while of man it is written (Genesis 2:7) that "He breathed into his face the breath of life." And so in the last chapter of Ecclesiastes (12:7) it is concluded: "(Before) the dust return into its earth from whence it was; and the spirit return to God Who gave it." Again the process of life is alike as to the body, concerning which it is written (Ecclesiastes 3:19): "All things breathe alike," and (Wisdom 2:2), "The breath in our nostrils is smoke." But the process is not alike of the soul; for man is intelligent, whereas animals are not. Hence it is false to say: "Man has nothing more than beasts." Thus death comes to both alike as to the body, by not as to the soul. ||

As a thing can be created by reason, not of a passive potentiality, but only of the active potentiality of the Creator, Who can produce something out of nothing, so when we say that a thing can be reduced to nothing, we do not imply in the creature a potentiality to non-existence, but in the Creator the power of ceasing to sustain existence.

-||<b>Iª q. 75 a. 7 co. </b>Respondeo dicendum quod Origenes posuit omnes animas humanas et Angelos esse unius speciei. Et hoc ideo, quia posuit diversitatem gradus in huiusmodi substantiis inventam, accidentalem, utpote ex libero arbitrio provenientem, ut supra dictum est. Quod non potest esse, quia in substantiis incorporeis non potest esse diversitas secundum numerum absque diversitate secundum speciem, et absque naturali inaequalitate. Quia si non sint compositae ex materia et forma, sed sint formae subsistentes, manifestum est quod necesse erit in eis esse diversitatem in specie. Non enim potest intelligi quod aliqua forma separata sit nisi una unius speciei, sicut si esset albedo separata, non posset esse nisi una tantum; haec enim albedo non differt ab illa nisi per hoc, quod est huius vel illius. Diversitas autem secundum speciem semper habet diversitatem naturalem concomitantem, sicut in speciebus colorum unus est perfectior altero, et similiter in aliis. Et hoc ideo, quia differentiae dividentes genus sunt contrariae; contraria autem se habent secundum perfectum et imperfectum, quia principium contrarietatis est privatio et habitus ut dicitur in X Metaphys. Idem etiam sequeretur, si huiusmodi substantiae essent compositae ex materia et forma. Si enim materia huius distinguitur a materia illius, necesse est quod vel forma sit principium distinctionis materiae, ut scilicet materiae sint diversae propter habitudinem ad diversas formas, et tunc sequitur adhuc diversitas secundum speciem et inaequalitas naturalis. Vel materia erit principium distinctionis formarum; nec poterit dici materia haec alia ab illa, nisi secundum divisionem quantitativam, quae non habet locum in substantiis incorporeis, cuiusmodi sunt Angelus et anima. Unde non potest esse quod Angelus et anima sint unius speciei. Quomodo autem sint plures animae unius speciei infra ostendetur.||I answer that, Origen (Peri Archon iii, 5) held that human souls and angels are all of the same species; and this because he supposed that in these substances the difference of degree was accidental, as resulting from their free-will: as we have seen above (47, 2). But this cannot be; for in incorporeal substances there cannot be diversity of number without diversity of species and inequality of nature; because, as they are not composed of matter and form, but are subsistent forms, it is clear that there is necessarily among them a diversity of species. For a separate form cannot be understood otherwise than as one of a single species; thus, supposing a separate whiteness to exist, it could only be one; forasmuch as one whiteness does not differ from another except as in this or that subject. But diversity of species is always accompanied with a diversity of nature; thus in species of colors one is more perfect than another; and the same applies to other species, because differences which divide a "genus" are contrary to one another. Contraries, however, are compared to one another as the perfect to the imperfect, since the "principle of contrariety is habit, and privation thereof," as is written Metaph. x (Did. ix, 4). The same would follow if the aforesaid substances were composed of matter and form. For if the matter of one be distinct from the matter of another, it follows that either the form is the principle of the distinction of matter--that is to say, that the matter is distinct on account of its relation to divers forms; and even then there would result a difference of species and inequality of nature: or else the matter is the principle of the distinction of forms. But one matter cannot be distinct from another, except by a distinction of quantity, which has no place in these incorporeal substances, such as an angel and the soul. So that it is not possible for the angel and the soul to be of the same species. How it is that there can be many souls of one species will be explained later (76, 2, ad 1). ||

The ultimate specific difference is the noblest because it is the most determinate, in the same way as actuality is nobler than potentiality. Thus, however, the intellectual faculty is not the noblest, because it is indeterminate and common to many degrees of intellectuality; as the sensible faculty is common to many degrees in the sensible nature.

The body is not of the essence of the soul; but the soul by the nature of its essence can be united to the body, so that, properly speaking, not the soul alone, but the "composite," is the species.

Further, every form is determined according to the nature of the matter of which it is the form; otherwise no proportion would be required between matter and form. Therefore if the intellect were united to the body as its form, since every body has a determinate nature, it would follow that the intellect has a determinate nature; and thus, it would not be capable of knowing all things, as is clear from what has been said (75, 2); which is contrary to the nature of the intellect.

Further, whatever receptive power is an act of a body, receives a form materially and individually; for what is received must be received according to the condition of the receiver. But the form of the thing understood is not received into the intellect materially and individually, but rather immaterially and universally: otherwise the intellect would not be capable of the knowledge of immaterial and universal objects, but only of individuals, like the senses.

But the intellectual action is not the action of a body, as appears from above (75, 2). Therefore neither is the intellectual faculty a power of the body.

But to be united to matter belongs to the form by reason of its nature; because form is the act of matter, not by an accidental quality, but by its own essence; otherwise matter and form would not make a thing substantially one, but only accidentally one. Therefore a form cannot be without its own proper matter. But the intellectual principle, since it is incorruptible, as was shown above (75, 6), remains separate from the body, after the dissolution of the body.

-||<b>Iª q. 76 a. 1 co. </b>Respondeo dicendum quod necesse est dicere quod intellectus, qui est intellectualis operationis principium, sit humani corporis forma. Illud enim quo primo aliquid operatur, est forma eius cui operatio attribuitur, sicut quo primo sanatur corpus, est sanitas, et quo primo scit anima, est scientia; unde sanitas est forma corporis, et scientia animae. Et huius ratio est, quia nihil agit nisi secundum quod est actu, unde quo aliquid est actu, eo agit. Manifestum est autem quod primum quo corpus vivit, est anima. Et cum vita manifestetur secundum diversas operationes in diversis gradibus viventium, id quo primo operamur unumquodque horum operum vitae, est anima, anima enim est primum quo nutrimur, et sentimus, et movemur secundum locum; et similiter quo primo intelligimus. Hoc ergo principium quo primo intelligimus, sive dicatur intellectus sive anima intellectiva, est forma corporis. Et haec est demonstratio Aristotelis in II de anima. Si quis autem velit dicere animam intellectivam non esse corporis formam, oportet quod inveniat modum quo ista actio quae est intelligere, sit huius hominis actio, experitur enim unusquisque seipsum esse qui intelligit. Attribuitur autem aliqua actio alicui tripliciter, ut patet per philosophum, V Physic., dicitur enim movere aliquid aut agere vel secundum se totum, sicut medicus sanat; aut secundum partem, sicut homo videt per oculum; aut per accidens, sicut dicitur quod album aedificat, quia accidit aedificatori esse album. Cum igitur dicimus Socratem aut Platonem intelligere, manifestum est quod non attribuitur ei per accidens, attribuitur enim ei inquantum est homo, quod essentialiter praedicatur de ipso. Aut ergo oportet dicere quod Socrates intelligit secundum se totum, sicut Plato posuit, dicens hominem esse animam intellectivam, aut oportet dicere quod intellectus sit aliqua pars Socratis. Et primum quidem stare non potest, ut supra ostensum est, propter hoc quod ipse idem homo est qui percipit se et intelligere et sentire, sentire autem non est sine corpore, unde oportet corpus aliquam esse hominis partem. Relinquitur ergo quod intellectus quo Socrates intelligit, est aliqua pars Socratis ita quod intellectus aliquo modo corpori Socratis uniatur. Hanc autem unionem Commentator, in III de anima, dicit esse per speciem intelligibilem. Quae quidem habet duplex subiectum, unum scilicet intellectum possibilem; et aliud ipsa phantasmata quae sunt in organis corporeis. Et sic per speciem intelligibilem continuatur intellectus possibilis corpori huius vel illius hominis. Sed ista continuatio vel unio non sufficit ad hoc quod actio intellectus sit actio Socratis. Et hoc patet per similitudinem in sensu, ex quo Aristoteles procedit ad considerandum ea quae sunt intellectus. Sic enim se habent phantasmata ad intellectum, ut dicitur in III de anima, sicut colores ad visum. Sicut ergo species colorum sunt in visu, ita species phantasmatum sunt in intellectu possibili. Patet autem quod ex hoc quod colores sunt in pariete, quorum similitudines sunt in visu, actio visus non attribuitur parieti, non enim dicimus quod paries videat, sed magis quod videatur. Ex hoc ergo quod species phantasmatum sunt in intellectu possibili, non sequitur quod Socrates, in quo sunt phantasmata, intelligat; sed quod ipse, vel eius phantasmata intelligantur. Quidam autem dicere voluerunt quod intellectus unitur corpori ut motor; et sic ex intellectu et corpore fit unum, ut actio intellectus toti attribui possit. Sed hoc est multipliciter vanum. Primo quidem, quia intellectus non movet corpus nisi per appetitum, cuius motus praesupponit operationem intellectus. Non ergo quia movetur Socrates ab intellectu, ideo intelligit, sed potius e converso, quia intelligit, ideo ab intellectu movetur Socrates. Secundo quia, cum Socrates sit quoddam individuum in natura cuius essentia est una, composita ex materia et forma; si intellectus non sit forma eius, sequitur quod sit praeter essentiam eius; et sic intellectus comparabitur ad totum Socratem sicut motor ad motum. Intelligere autem est actio quiescens in agente, non autem transiens in alterum, sicut calefactio. Non ergo intelligere potest attribui Socrati propter hoc quod est motus ab intellectu. Tertio, quia actio motoris nunquam attribuitur moto nisi sicut instrumento, sicut actio carpentarii serrae. Si igitur intelligere attribuitur Socrati quia est actio motoris eius, sequitur quod attribuatur ei sicut instrumento. Quod est contra philosophum, qui vult quod intelligere non sit per instrumentum corporeum. Quarto quia, licet actio partis attribuatur toti, ut actio oculi homini; nunquam tamen attribuitur alii parti, nisi forte per accidens, non enim dicimus quod manus videat, propter hoc quod oculus videt. Si ergo ex intellectu et Socrate dicto modo fit unum, actio intellectus non potest attribui Socrati. Si vero Socrates est totum quod componitur ex unione intellectus ad reliqua quae sunt Socratis, et tamen intellectus non unitur aliis quae sunt Socratis nisi sicut motor; sequitur quod Socrates non sit unum simpliciter, et per consequens nec ens simpliciter; sic enim aliquid est ens, quomodo et unum. Relinquitur ergo solus modus quem Aristoteles ponit, quod hic homo intelligit, quia principium intellectivum est forma ipsius. Sic ergo ex ipsa operatione intellectus apparet quod intellectivum principium unitur corpori ut forma. Potest etiam idem manifestari ex ratione speciei humanae. Natura enim uniuscuiusque rei ex eius operatione ostenditur. Propria autem operatio hominis, inquantum est homo, est intelligere, per hanc enim omnia animalia transcendit. Unde et Aristoteles, in libro Ethic., in hac operatione, sicut in propria hominis, ultimam felicitatem constituit. Oportet ergo quod homo secundum illud speciem sortiatur, quod est huius operationis principium. Sortitur autem unumquodque speciem per propriam formam. Relinquitur ergo quod intellectivum principium sit propria hominis forma. Sed considerandum est quod, quanto forma est nobilior, tanto magis dominatur materiae corporali, et minus ei immergitur, et magis sua operatione vel virtute excedit eam. Unde videmus quod forma mixti corporis habet aliquam operationem quae non causatur ex qualitatibus elementaribus. Et quanto magis proceditur in nobilitate formarum, tanto magis invenitur virtus formae materiam elementarem excedere, sicut anima vegetabilis plus quam forma metalli, et anima sensibilis plus quam anima vegetabilis. Anima autem humana est ultima in nobilitate formarum. Unde intantum sua virtute excedit materiam corporalem, quod habet aliquam operationem et virtutem in qua nullo modo communicat materia corporalis. Et haec virtus dicitur intellectus. Est autem attendendum quod, si quis poneret animam componi ex materia et forma, nullo modo posset dicere animam esse formam corporis. Cum enim forma sit actus, materia vero sit ens in potentia tantum; nullo modo id quod est ex materia et forma compositum, potest esse alterius forma secundum se totum. Si autem secundum aliquid sui sit forma, id quod est forma dicimus animam, et id cuius est forma dicimus primum animatum, ut supra dictum est.||I answer that, We must assert that the intellect which is the principle of intellectual operation is the form of the human body. For that whereby primarily anything acts is a form of the thing to which the act is to be attributed: for instance, that whereby a body is primarily healed is health, and that whereby the soul knows primarily is knowledge; hence health is a form of the body, and knowledge is a form of the soul. The reason is because nothing acts except so far as it is in act; wherefore a thing acts by that whereby it is in act. Now it is clear that the first thing by which the body lives is the soul. And as life appears through various operations in different degrees of living things, that whereby we primarily perform each of all these vital actions is the soul. For the soul is the primary principle of our nourishment, sensation, and local movement; and likewise of our understanding. Therefore this principle by which we primarily understand, whether it be called the intellect or the intellectual soul, is the form of the body. This is the demonstration used by Aristotle (De Anima ii, 2). But if anyone says that the intellectual soul is not the form of the body he must first explain how it is that this action of understanding is the action of this particular man; for each one is conscious that it is himself who understands. Now an action may be attributed to anyone in three ways, as is clear from the Philosopher (Phys. v, 1); for a thing is said to move or act, either by virtue of its whole self, for instance, as a physician heals; or by virtue of a part, as a man sees by his eye; or through an accidental quality, as when we say that something that is white builds, because it is accidental to the builder to be white. So when we say that Socrates or Plato understands, it is clear that this is not attributed to him accidentally; since it is ascribed to him as man, which is predicated of him essentially. We must therefore say either that Socrates understands by virtue of his whole self, as Plato maintained, holding that man is an intellectual soul; or that intelligence is a part of Socrates. The first cannot stand, as was shown above (75, 4), for this reason, that it is one and the same man who is conscious both that he understands, and that he senses. But one cannot sense without a body: therefore the body must be some part of man. It follows therefore that the intellect by which Socrates understands is a part of Socrates, so that in some way it is united to the body of Socrates. The Commentator held that this union is through the intelligible species, as having a double subject, in the possible intellect, and in the phantasms which are in the corporeal organs. Thus through the intelligible species the possible intellect is linked to the body of this or that particular man. But this link or union does not sufficiently explain the fact, that the act of the intellect is the act of Socrates. This can be clearly seen from comparison with the sensitive faculty, from which Aristotle proceeds to consider things relating to the intellect. For the relation of phantasms to the intellect is like the relation of colors to the sense of sight, as he says De Anima iii, 5,7. Therefore, as the species of colors are in the sight, so are the species of phantasms in the possible intellect. Now it is clear that because the colors, the images of which are in the sight, are on a wall, the action of seeing is not attributed to the wall: for we do not say that the wall sees, but rather that it is seen. Therefore, from the fact that the species of phantasms are in the possible intellect, it does not follow that Socrates, in whom are the phantasms, understands, but that he or his phantasms are understood. Some, however, tried to maintain that the intellect is united to the body as its motor; and hence that the intellect and body form one thing so that the act of the intellect could be attributed to the whole. This is, however, absurd for many reasons. First, because the intellect does not move the body except through the appetite, the movement of which presupposes the operation of the intellect. The reason therefore why Socrates understands is not because he is moved by his intellect, but rather, contrariwise, he is moved by his intellect because he understands. Secondly, because since Socrates is an individual in a nature of one essence composed of matter and form, if the intellect be not the form, it follows that it must be outside the essence, and then the intellect is the whole Socrates as a motor to the thing moved. Whereas the act of intellect remains in the agent, and does not pass into something else, as does the action of heating. Therefore the action of understanding cannot be attributed to Socrates for the reason that he is moved by his intellect. Thirdly, because the action of a motor is never attributed to the thing moved, except as to an instrument; as the action of a carpenter to a saw. Therefore if understanding is attributed to Socrates, as the action of what moves him, it follows that it is attributed to him as to an instrument. This is contrary to the teaching of the Philosopher, who holds that understanding is not possible through a corporeal instrument (De Anima iii, 4). Fourthly, because, although the action of a part be attributed to the whole, as the action of the eye is attributed to a man; yet it is never attributed to another part, except perhaps indirectly; for we do not say that the hand sees because the eye sees. Therefore if the intellect and Socrates are united in the above manner, the action of the intellect cannot be attributed to Socrates. If, however, Socrates be a whole composed of a union of the intellect with whatever else belongs to Socrates, and still the intellect be united to those other things only as a motor, it follows that Socrates is not one absolutely, and consequently neither a being absolutely, for a thing is a being according as it is one. There remains, therefore, no other explanation than that given by Aristotle--namely, that this particular man understands, because the intellectual principle is his form. Thus from the very operation of the intellect it is made clear that the intellectual principle is united to the body as its form. The same can be clearly shown from the nature of the human species. For the nature of each thing is shown by its operation. Now the proper operation of man as man is to understand; because he thereby surpasses all other animals. Whence Aristotle concludes (Ethic. x, 7) that the ultimate happiness of man must consist in this operation as properly belonging to him. Man must therefore derive his species from that which is the principle of this operation. But the species of anything is derived from its form. It follows therefore that the intellectual principle is the proper form of man. But we must observe that the nobler a form is, the more it rises above corporeal matter, the less it is merged in matter, and the more it excels matter by its power and its operation; hence we find that the form of a mixed body has another operation not caused by its elemental qualities. And the higher we advance in the nobility of forms, the more we find that the power of the form excels the elementary matter; as the vegetative soul excels the form of the metal, and the sensitive soul excels the vegetative soul. Now the human soul is the highest and noblest of forms. Wherefore it excels corporeal matter in its power by the fact that it has an operation and a power in which corporeal matter has no share whatever. This power is called the intellect. It is well to remark that if anyone holds that the soul is composed of matter and form, it would follow that in no way could the soul be the form of the body. For since the form is an act, and matter is only in potentiality, that which is composed of matter and form cannot be the form of another by virtue of itself as a whole. But if it is a form by virtue of some part of itself, then that part which is the form we call the soul, and that of which it is the form we call the "primary animate," as was said above (75, 5). ||

Sic ergo philosophus dicit in III de anima quod intellectus est separatus, quia non est virtus alicuius organi corporalis.||Reply to Objection 1. As the Philosopher says (Phys. ii, 2), the ultimate natural form to which the consideration of the natural philosopher is directed is indeed separate; yet it exists in matter. He proves this from the fact that "man and the sun generate man from matter." It is separate indeed according to its intellectual power, because the intellectual power does not belong to a corporeal organ, as the power of seeing is the act of the eye; for understanding is an act which cannot be performed by a corporeal organ, like the act of seeing. But it exists in matter so far as the soul itself, to which this power belongs, is the form of the body, and the term of human generation. And so the Philosopher says (De Anima iii) that the intellect is separate, because it is not the faculty of a corporeal organ. From this it is clear how to answer the Second and Third objections: since, in order that man may be able to understand all things by means of his intellect, and that his intellect may understand immaterial things and universals, it is sufficient that the intellectual power be not the act of the body. ||

Quod non accidit in aliis formis, quae non sunt subsistentes. Et propter hoc anima humana remanet in suo esse, destructo corpore, non autem aliae formae.||Reply to Objection 5. The soul communicates that existence in which it subsists to the corporeal matter, out of which and the intellectual soul there results unity of existence; so that the existence of the whole composite is also the existence of the soul. This is not the case with other non-subsistent forms. For this reason the human soul retains its own existence after the dissolution of the body; whereas it is not so with other forms. ||

To be united to the body belongs to the soul by reason of itself, as it belongs to a light body by reason of itself to be raised up. And as a light body remains light, when removed from its proper place, retaining meanwhile an aptitude and an inclination for its proper place; so the human soul retains its proper existence when separated from the body, having an aptitude and a natural inclination to be united to the body. ||

Videtur quod intellectivum principium non multiplicetur secundum multiplicationem corporum, sed sit unus intellectus in omnibus hominibus. Nulla enim substantia immaterialis multiplicatur secundum numerum in una specie. Anima autem humana est substantia immaterialis, non enim est composita ex materia et forma, ut supra ostensum est. Non ergo sunt multae in una specie. Sed omnes homines sunt unius speciei. Est ergo unus intellectus omnium hominum.||Objection 1. It would seem that the intellectual principle is not multiplied according to the number of bodies, but that there is one intellect in all men. For an immaterial substance is not multiplied in number within one species. But the human soul is an immaterial substance; since it is not composed of matter and form as was shown above (75, 5). Therefore there are not many human souls in one species. But all men are of one species. Therefore there is but one intellect in all men. ||

Therefore, if human souls were multiplied according to the number of bodies, it follows that the bodies being removed, the number of souls would not remain; but from all the souls there would be but a single remainder. This is heretical; for it would do away with the distinction of rewards and punishments. ||

Ergo species rerum in intellectu meo et tuo reciperentur individualiter, quod est contra rationem intellectus, qui est cognoscitivus universalium.||Objection 3. Further, if my intellect is distinct from your intellect, my intellect is an individual, and so is yours; for individuals are things which differ in number but agree in one species.

Therefore the species of things would be received individually into my intellect, and also into yours: which is contrary to the nature of the intellect which knows universals. ||

Further, the thing understood is in the intellect which understands. If, therefore, my intellect is distinct from yours, what is understood by me must be distinct from what is understood by you; and consequently it will be reckoned as something individual, and be only potentially something understood; so that the common intention will have to be abstracted from both; since from things diverse something intelligible common to them may be abstracted.

-||<b>Iª q. 76 a. 2 co. </b>Respondeo dicendum quod intellectum esse unum omnium hominum, omnino est impossibile. Et hoc quidem patet, si, secundum Platonis sententiam homo sit ipse intellectus. Sequeretur enim, si Socratis et Platonis est unus intellectus tantum, quod Socrates et Plato sint unus homo; et quod non distinguantur ab invicem nisi per hoc quod est extra essentiam utriusque. Et erit tunc distinctio Socratis et Platonis non alia quam hominis tunicati et cappati, quod est omnino absurdum. Similiter etiam patet hoc esse impossibile, si, secundum sententiam Aristotelis, intellectus ponatur pars, seu potentia, animae quae est hominis forma. Impossibile est enim plurium numero diversorum esse unam formam, sicut impossibile est quod eorum sit unum esse, nam forma est essendi principium. Similiter etiam patet hoc esse impossibile quocumque modo quis ponat unionem intellectus ad hunc et ad illum hominem. Manifestum est enim quod, si sit unum principale agens et duo instrumenta, dici poterit unum agens simpliciter, sed plures actiones, sicut si unus homo tangat diversa duabus manibus, erit unus tangens, sed duo tactus. Si vero e converso instrumentum sit unum et principales agentes diversi, dicentur quidem plures agentes, sed una actio, sicut si multi uno fune trahant navem, erunt multi trahentes, sed unus tractus. Si vero agens principale sit unum et instrumentum unum, dicetur unum agens et una actio, sicut cum faber uno martello percutit, est unus percutiens et una percussio. Manifestum est autem quod, qualitercumque intellectus seu uniatur seu copuletur huic vel illi homini, intellectus inter cetera quae ad hominem pertinent, principalitatem habet, obediunt enim vires sensitivae intellectui, et ei deserviunt. Si ergo poneretur quod essent plures intellectus et sensus unus duorum hominum, puta si duo homines haberent unum oculum; essent quidem plures videntes, sed una visio. Si vero intellectus est unus, quantumcumque diversificentur alia quibus omnibus intellectus utitur quasi instrumentis, nullo modo Socrates et Plato poterunt dici nisi unus intelligens. Et si addamus quod ipsum intelligere, quod est actio intellectus, non fit per aliquod aliud organum, nisi per ipsum intellectum; sequetur ulterius quod sit et agens unum et actio una; idest quod omnes homines sint unus intelligens, et unum intelligere; dico autem respectu eiusdem intelligibilis. Posset autem diversificari actio intellectualis mea et tua per diversitatem phantasmatum, quia scilicet aliud est phantasma lapidis in me et aliud in te, si ipsum phantasma, secundum quod est aliud in me et aliud in te, esset forma intellectus possibilis, quia idem agens secundum diversas formas producit diversas actiones, sicut secundum diversas formas rerum respectu eiusdem oculi sunt diversae visiones. Sed ipsum phantasma non est forma intellectus possibilis, sed species intelligibilis quae a phantasmatibus abstrahitur. In uno autem intellectu a phantasmatibus diversis eiusdem speciei non abstrahitur nisi una species intelligibilis. Sicut in uno homine apparet, in quo possunt esse diversa phantasmata lapidis, et tamen ab omnibus eis abstrahitur una species intelligibilis lapidis, per quam intellectus unius hominis operatione una intelligit naturam lapidis, non obstante diversitate phantasmatum. Si ergo unus intellectus esset omnium hominum, diversitas phantasmatum quae sunt in hoc et in illo, non posset causare diversitatem intellectualis operationis huius et illius hominis, ut Commentator fingit in III de anima. Relinquitur ergo quod omnino impossibile et inconveniens est ponere unum intellectum omnium hominum.||I answer that, It is absolutely impossible for one intellect to belong to all men. This is clear if, as Plato maintained, man is the intellect itself. For it would follow that Socrates and Plato are one man; and that they are not distinct from each other, except by something outside the essence of each. The distinction between Socrates and Plato would be no other than that of one man with a tunic and another with a cloak; which is quite absurd. It is likewise clear that this is impossible if, according to the opinion of Aristotle (De Anima ii, 2), it is supposed that the intellect is a part or a power of the soul which is the form of man. For it is impossible for many distinct individuals to have one form, as it is impossible for them to have one existence, for the form is the principle of existence. Again, this is clearly impossible, whatever one may hold as to the manner of the union of the intellect to this or that man. For it is manifest that, supposing there is one principal agent, and two instruments, we can say that there is one agent absolutely, but several actions; as when one man touches several things with his two hands, there will be one who touches, but two contacts. If, on the contrary, we suppose one instrument and several principal agents, we might say that there are several agents, but one act; for example, if there be many drawing a ship by means of a rope; there will be many drawing, but one pull. If, however, there is one principal agent, and one instrument, we say that there is one agent and one action, as when the smith strikes with one hammer, there is one striker and one stroke. Now it is clear that no matter how the intellect is united or coupled to this or that man, the intellect has the precedence of all the other things which appertain to man; for the sensitive powers obey the intellect, and are at its service. Therefore, if we suppose two men to have several intellects and one sense--for instance, if two men had one eye--there would be several seers, but one sight. But if there is one intellect, no matter how diverse may be all those things of which the intellect makes use as instruments, in no way is it possible to say that Socrates and Plato are otherwise than one understanding man. And if to this we add that to understand, which is the act of the intellect, is not affected by any organ other than the intellect itself; it will further follow that there is but one agent and one action: that is to say that all men are but one "understander," and have but one act of understanding, in regard, that is, of one intelligible object. However, it would be possible to distinguish my intellectual action form yours by the distinction of the phantasms--that is to say, were there one phantasm of a stone in me, and another in you--if the phantasm itself, as it is one thing in me and another in you, were a form of the possible intellect; since the same agent according to divers forms produces divers actions; as, according to divers forms of things with regard to the same eye, there are divers visions. But the phantasm itself is not a form of the possible intellect; it is the intelligible species abstracted from the phantasm that is a form. Now in one intellect, from different phantasms of the same species, only one intelligible species is abstracted; as appears in one man, in whom there may be different phantasms of a stone; yet from all of them only one intelligible species of a stone is abstracted; by which the intellect of that one man, by one operation, understands the nature of a stone, notwithstanding the diversity of phantasms. Therefore, if there were one intellect for all men, the diversity of phantasms which are in this one and that one would not cause a diversity of intellectual operation in this man and that man. It follows, therefore, that it is altogether impossible and unreasonable to maintain that there exists one intellect for all men. ||

Although the intellectual soul, like an angel, has no matter from which it is produced, yet it is the form of a certain matter; in which it is unlike an angel.

Now it is clear that the intellectual soul, by virtue of its very being, is united to the body as its form; yet, after the dissolution of the body, the intellectual soul retains its own being.

-||<b>Iª q. 76 a. 2 ad 3 </b>Ad tertium dicendum quod individuatio intelligentis, aut speciei per quam intelligit, non excludit intelligentiam universalium, alioquin, cum intellectus separati sint quaedam substantiae subsistentes, et per consequens particulares, non possent universalia intelligere. Sed materialitas cognoscentis et speciei per quam cognoscitur, universalis cognitionem impedit. Sicut enim omnis actio est secundum modum formae qua agens agit, ut calefactio secundum modum caloris; ita cognitio est secundum modum speciei qua cognoscens cognoscit. Manifestum est autem quod natura communis distinguitur et multiplicatur secundum principia individuantia, quae sunt ex parte materiae. Si ergo forma per quam fit cognitio, sit materialis, non abstracta a conditionibus materiae, erit similitudo naturae speciei aut generis, secundum quod est distincta et multiplicata per principia individuantia, et ita non poterit cognosci natura rei in sua communitate. Si vero species sit abstracta a conditionibus materiae individualis, erit similitudo naturae absque iis quae ipsam distinguunt et multiplicant, et ita cognoscetur universale. Nec refert, quantum ad hoc, utrum sit unus intellectus vel plures, quia si etiam esset unus tantum, oporteret ipsum esse aliquem quendam, et speciem per quam intelligit esse aliquam quandam.||Reply to Objection 3. Individuality of the intelligent being, or of the species whereby it understands, does not exclude the understanding of universals; otherwise, since separate intellects are subsistent substances, and consequently individual, they could not understand universals. But the materiality of the knower, and of the species whereby it knows, impedes the knowledge of the universal. For as every action is according to the mode of the form by which the agent acts, as heating is according to the mode of the heat; so knowledge is according to the mode of the species by which the knower knows. Now it is clear that common nature becomes distinct and multiplied by reason of the individuating principles which come from the matter. Therefore if the form, which is the means of knowledge, is material--that is, not abstracted from material conditions--its likeness to the nature of a species or genus will be according to the distinction and multiplication of that nature by means of individuating principles; so that knowledge of the nature of a thing in general will be impossible. But if the species be abstracted from the conditions of individual matter, there will be a likeness of the nature without those things which make it distinct and multiplied; thus there will be knowledge of the universal. Nor does it matter, as to this particular point, whether there be one intellect or many; because, even if there were but one, it would necessarily be an individual intellect, and the species whereby it understands, an individual species. ||

-||<b>Iª q. 76 a. 2 ad 4 </b>Ad quartum dicendum quod, sive intellectus sit unus sive plures, id quod intelligitur est unum. Id enim quod intelligitur non est in intellectu secundum se, sed secundum suam similitudinem, lapis enim non est in anima, sed species lapidis, ut dicitur in III de anima. Et tamen lapis est id quod intelligitur, non autem species lapidis, nisi per reflexionem intellectus supra seipsum, alioquin scientiae non essent de rebus, sed de speciebus intelligibilibus. Contingit autem eidem rei diversa secundum diversas formas assimilari. Et quia cognitio fit secundum assimilationem cognoscentis ad rem cognitam, sequitur quod idem a diversis cognoscentibus cognosci contingit, ut patet in sensu, nam plures vident eundem colorem, secundum diversas similitudines. Et similiter plures intellectus intelligunt unam rem intellectam. Sed hoc tantum interest inter sensum et intellectum, secundum sententiam Aristotelis, quod res sentitur secundum illam dispositionem quam extra animam habet, in sua particularitate, natura autem rei quae intelligitur, est quidem extra animam, sed non habet illum modum essendi extra animam, secundum quem intelligitur. Intelligitur enim natura communis seclusis principiis individuantibus; non autem hunc modum essendi habet extra animam. Sed secundum sententiam Platonis, res intellecta eo modo est extra animam quo intelligitur, posuit enim naturas rerum a materia separatas.||Reply to Objection 4. Whether the intellect be one or many, what is understood is one; for what is understood is in the intellect, not according to its own nature, but according to its likeness; for "the stone is not in the soul, but its likeness is," as is said, De Anima iii, 8. Yet it is the stone which is understood, not the likeness of the stone; except by a reflection of the intellect on itself: otherwise, the objects of sciences would not be things, but only intelligible species. Now it happens that different things, according to different forms, are likened to the same thing. And since knowledge is begotten according to the assimilation of the knower to the thing known, it follows that the same thing may happen to be known by several knowers; as is apparent in regard to the senses; for several see the same color, according to different likenesses. In the same way several intellects understand one object understood. But there is this difference, according to the opinion of Aristotle, between the sense and the intelligence--that a thing is perceived by the sense according to the disposition which it has outside the soul --that is, in its individuality; whereas the nature of the thing understood is indeed outside the soul, but the mode according to which it exists outside the soul is not the mode according to which it is understood. For the common nature is understood as apart from the individuating principles; whereas such is not its mode of existence outside the soul. But, according to the opinion of Plato, the thing understood exists outside the soul in the same condition as those under which it is understood; for he supposed that the natures of things exist separate from matter. ||

It would seem that besides the intellectual soul there are in man other souls essentially different from one another, such as the sensitive soul and the nutritive soul. For corruptible and incorruptible are not of the same substance.

Further, if it be said that the sensitive soul in man is incorruptible; on the contrary, "corruptible and incorruptible differ generically," says the Philosopher, Metaph. x (Did. ix, 10). But the sensitive soul in the horse, the lion, and other brute animals, is corruptible. If, therefore, in man it be incorruptible, the sensitive soul in man and brute animals will not be of the same "genus." Now an animal is so called from its having a sensitive soul; and, therefore, "animal" will not be one genus common to man and other animals, which is absurd. ||

Further, the Philosopher says, Metaph. viii (Did. vii, 2), that the genus is taken from the matter, and difference from the form. But "rational," which is the difference constituting man, is taken from the intellectual soul; while he is called "animal" by reason of his having a body animated by a sensitive soul.

Therefore in man the intellectual soul is not essentially the same as the sensitive soul, but presupposes it as a material subject. ||

-||<b>Iª q. 76 a. 3 co. </b>Respondeo dicendum quod Plato posuit diversas animas esse in corpore uno, etiam secundum organa distinctas, quibus diversa opera vitae attribuebat; dicens vim nutritivam esse in hepate, concupiscibilem in corde, cognoscitivam in cerebro. Quam quidem opinionem Aristoteles reprobat, in libro de anima, quantum ad illas animae partes quae corporeis organis in suis operibus utuntur, ex hoc quod in animalibus quae decisa vivunt, in qualibet parte inveniuntur diversae operationes animae, sicut sensus et appetitus. Hoc autem non esset, si diversa principia operationum animae, tanquam per essentiam diversae, diversis partibus corporis distributa essent. Sed de intellectiva sub dubio videtur relinquere utrum sit separata ab aliis partibus animae solum ratione, an etiam loco. Opinio autem Platonis sustineri utique posset, si poneretur quod anima unitur corpori, non ut forma, sed ut motor, ut posuit Plato. Nihil enim inconveniens sequitur, si idem mobile a diversis motoribus moveatur, praecipue secundum diversas partes. Sed si ponamus animam corpori uniri sicut formam, omnino impossibile videtur plures animas per essentiam differentes in uno corpore esse. Quod quidem triplici ratione manifestari potest. Primo quidem, quia animal non esset simpliciter unum, cuius essent animae plures. Nihil enim est simpliciter unum nisi per formam unam, per quam habet res esse, ab eodem enim habet res quod sit ens et quod sit una; et ideo ea quae denominantur a diversis formis, non sunt unum simpliciter, sicut homo albus. Si igitur homo ab alia forma haberet quod sit vivum, scilicet ab anima vegetabili; et ab alia forma quod sit animal, scilicet ab anima sensibili; et ab alia quod sit homo, scilicet ab anima rationali; sequeretur quod homo non esset unum simpliciter, sicut et Aristoteles argumentatur contra Platonem, in VIII Metaphys., quod si alia esset idea animalis, et alia bipedis, non esset unum simpliciter animal bipes. Et propter hoc, in I de anima, contra ponentes diversas animas in corpore, inquirit quid contineat illas, idest quid faciat ex eis unum. Et non potest dici quod uniantur per corporis unitatem, quia magis anima continet corpus, et facit ipsum esse unum, quam e converso. Secundo, hoc apparet impossibile ex modo praedicationis. Quae enim sumuntur a diversis formis, praedicantur ad invicem vel per accidens, si formae non sint ad invicem ordinatae, puta cum dicimus quod album est dulce, vel, si formae sint ordinatae ad invicem, erit praedicatio per se, in secundo modo dicendi per se, quia subiectum ponitur in definitione praedicati. Sicut superficies praeambula est ad colorem, si ergo dicamus quod corpus superficiatum est coloratum, erit secundus modus praedicationis per se. Si ergo alia forma sit a qua aliquid dicitur animal, et a qua aliquid dicitur homo, sequeretur quod vel unum horum non possit praedicari de altero nisi per accidens, si istae duae formae ad invicem ordinem non habent; vel quod sit ibi praedicatio in secundo modo dicendi per se, si una animarum sit ad aliam praeambula. Utrumque autem horum est manifeste falsum, quia animal per se de homine praedicatur, non per accidens; homo autem non ponitur in definitione animalis, sed e converso. Ergo oportet eandem formam esse per quam aliquid est animal, et per quam aliquid est homo, alioquin homo non vere esset id quod est animal, ut sic animal per se de homine praedicetur. Tertio, apparet hoc esse impossibile per hoc, quod una operatio animae, cum fuerit intensa, impedit aliam. Quod nullo modo contingeret, nisi principium actionum esset per essentiam unum. Sic ergo dicendum quod eadem numero est anima in homine sensitiva et intellectiva et nutritiva. Quomodo autem hoc contingat, de facili considerari potest, si quis differentias specierum et formarum attendat. Inveniuntur enim rerum species et formae differre ab invicem secundum perfectius et minus perfectum, sicut in rerum ordine animata perfectiora sunt inanimatis, et animalia plantis, et homines animalibus brutis, et in singulis horum generum sunt gradus diversi. Et ideo Aristoteles, in VIII Metaphys., assimilat species rerum numeris, qui differunt specie secundum additionem vel subtractionem unitatis. Et in II de anima, comparat diversas animas speciebus figurarum, quarum una continet aliam; sicut pentagonum continet tetragonum, et excedit. Sic igitur anima intellectiva continet in sua virtute quidquid habet anima sensitiva brutorum, et nutritiva plantarum. Sicut ergo superficies quae habet figuram pentagonam, non per aliam figuram est tetragona, et per aliam pentagona; quia superflueret figura tetragona, ex quo in pentagona continetur; ita nec per aliam animam Socrates est homo, et per aliam animal, sed per unam et eandem.||I answer that, Plato held that there were several souls in one body, distinct even as to organs, to which souls he referred the different vital actions, saying that the nutritive power is in the liver, the concupiscible in the heart, and the power of knowledge in the brain. Which opinion is rejected by Aristotle (De Anima ii, 2), with regard to those parts of the soul which use corporeal organs; for this reason, that in those animals which continue to live when they have been divided in each part are observed the operations of the soul, as sense and appetite. Now this would not be the case if the various principles of the soul's operations were essentially different, and distributed in the various parts of the body. But with regard to the intellectual part, he seems to leave it in doubt whether it be "only logically" distinct from the other parts of the soul, "or also locally." The opinion of Plato might be maintained if, as he held, the soul was supposed to be united to the body, not as its form, but as its motor. For it involves nothing unreasonable that the same movable thing be moved by several motors; and still less if it be moved according to its various parts. If we suppose, however, that the soul is united to the body as its form, it is quite impossible for several essentially different souls to be in one body. This can be made clear by three different reasons. In the first place, an animal would not be absolutely one, in which there were several souls. For nothing is absolutely one except by one form, by which a thing has existence: because a thing has from the same source both existence and unity; and therefore things which are denominated by various forms are not absolutely one; as, for instance, "a white man." If, therefore, man were 'living' by one form, the vegetative soul, and 'animal' by another form, the sensitive soul, and "man" by another form, the intellectual soul, it would follow that man is not absolutely one. Thus Aristotle argues, Metaph. viii (Did. vii, 6), against Plato, that if the idea of an animal is distinct from the idea of a biped, then a biped animal is not absolutely one. For this reason, against those who hold that there are several souls in the body, he asks (De Anima i, 5), "what contains them?"--that is, what makes them one? It cannot be said that they are united by the one body; because rather does the soul contain the body and make it one, than the reverse. Secondly, this is proved to be impossible by the manner in which one thing is predicated of another. Those things which are derived from various forms are predicated of one another, either accidentally, (if the forms are not ordered to one another, as when we say that something white is sweet), or essentially, in the second manner of essential predication, (if the forms are ordered one to another, the subject belonging to the definition of the predicate; as a surface is presupposed to color; so that if we say that a body with a surface is colored, we have the second manner of essential predication.) Therefore, if we have one form by which a thing is an animal, and another form by which it is a man, it follows either that one of these two things could not be predicated of the other, except accidentally, supposing these two forms not to be ordered to one another--or that one would be predicated of the other according to the second manner of essential predication, if one soul be presupposed to the other. But both of these consequences are clearly false: because "animal" is predicated of man essentially and not accidentally; and man is not part of the definition of an animal, but the other way about. Therefore of necessity by the same form a thing is animal and man; otherwise man would not really be the thing which is an animal, so that animal can be essentially predicated of man. Thirdly, this is shown to be impossible by the fact that when one operation of the soul is intense it impedes another, which could never be the case unless the principle of action were essentially one. We must therefore conclude that in man the sensitive soul, the intellectual soul, and the nutritive soul are numerically one soul. This can easily be explained, if we consider the differences of species and forms. For we observe that the species and forms of things differ from one another, as the perfect and imperfect; as in the order of things, the animate are more perfect than the inanimate, and animals more perfect than plants, and man than brute animals; and in each of these genera there are various degrees. For this reason Aristotle, Metaph. viii (Did. vii, 3), compares the species of things to numbers, which differ in species by the addition or subtraction of unity. And (De Anima ii, 3) he compares the various souls to the species of figures, one of which contains another; as a pentagon contains and exceeds a tetragon. Thus the intellectual soul contains virtually whatever belongs to the sensitive soul of brute animals, and to the nutritive souls of plants. Therefore, as a surface which is of a pentagonal shape, is not tetragonal by one shape, and pentagonal by another--since a tetragonal shape would be superfluous as contained in the pentagonal--so neither is Socrates a man by one soul, and animal by another; but by one and the same soul he is both animal and man. ||

Licet enim sensitivum incorruptionem non det, tamen incorruptionem intellectivo auferre non potest.||Reply to Objection 1. The sensitive soul is incorruptible, not by reason of its being sensitive, but by reason of its being intellectual. When, therefore, a soul is sensitive only, it is corruptible; but when with sensibility it has also intellectuality, it is incorruptible. For although sensibility does not give incorruptibility, yet it cannot deprive intellectuality of its incorruptibility. ||

We must not consider the diversity of natural things as proceeding from the various logical notions or intentions, which flow from our manner of understanding, because reason can apprehend one and the same thing in various ways. Therefore since, as we have said, the intellectual soul contains virtually what belongs to the sensitive soul, and something more, reason can consider separately what belongs to the power of the sensitive soul, as something imperfect and material. And because it observes that this is something common to man and to other animals, it forms thence the notion of the "genus"; while that wherein the intellectual soul exceeds the sensitive soul, it takes as formal and perfecting; thence it gathers the "difference" of man. ||

It would seem that in man there is another form besides the intellectual soul. For the Philosopher says (De Anima ii, 1), that "the soul is the act of a physical body which has life potentially."

Now everything that moves itself is divided into two parts, of which one moves, and the other is moved, as the Philosopher proves (Phys. viii, 5). But the part which moves is the soul. Therefore the other part must be such that it can be moved. But primary matter cannot be moved (Phys. v, 1), since it is a being only potentially; indeed everything that is moved is a body. Therefore in man and in every animal there must be another substantial form, by which the body is constituted. ||

Further, the order of forms depends on their relation to primary matter; for "before" and "after" apply by comparison to some beginning.

-||<b>Iª q. 76 a. 4 co. </b>Respondeo dicendum quod, si poneretur anima intellectiva non uniri corpori ut forma, sed solum ut motor, ut Platonici posuerunt; necesse esset dicere quod in homine esset alia forma substantialis, per quam corpus ab anima mobile in suo esse constitueretur. Sed si anima intellectiva unitur corpori ut forma substantialis, sicut supra iam diximus, impossibile est quod aliqua alia forma substantialis praeter eam inveniatur in homine. Ad cuius evidentiam, considerandum est quod forma substantialis in hoc a forma accidentali differt quia forma accidentalis non dat esse simpliciter, sed esse tale, sicut calor facit suum subiectum non simpliciter esse, sed esse calidum. Et ideo cum advenit forma accidentalis, non dicitur aliquid fieri vel generari simpliciter, sed fieri tale aut aliquo modo se habens, et similiter cum recedit forma accidentalis, non dicitur aliquid corrumpi simpliciter, sed secundum quid. Forma autem substantialis dat esse simpliciter, et ideo per eius adventum dicitur aliquid simpliciter generari, et per eius recessum simpliciter corrumpi. Et propter hoc antiqui naturales, qui posuerunt materiam primam esse aliquod ens actu, puta ignem aut aerem aut aliquid huiusmodi, dixerunt quod nihil generatur aut corrumpitur simpliciter, sed omne fieri statuerunt alterari, ut dicitur in I Physic. Si igitur ita esset, quod praeter animam intellectivam praeexisteret quaecumque alia forma substantialis in materia, per quam subiectum animae esset ens actu; sequeretur quod anima non daret esse simpliciter; et per consequens quod non esset forma substantialis; et quod per adventum animae non esset generatio simpliciter, neque per eius abscessum corruptio simpliciter, sed solum secundum quid. Quae sunt manifeste falsa. Unde dicendum est quod nulla alia forma substantialis est in homine, nisi sola anima intellectiva; et quod ipsa, sicut virtute continet animam sensitivam et nutritivam, ita virtute continet omnes inferiores formas, et facit ipsa sola quidquid imperfectiores formae in aliis faciunt. Et similiter est dicendum de anima sensitiva in brutis, et de nutritiva in plantis, et universaliter de omnibus formis perfectioribus respectu imperfectiorum.||I answer that, If we suppose that the intellectual soul is not united to the body as its form, but only as its motor, as the Platonists maintain, it would necessarily follow that in man there is another substantial form, by which the body is established in its being as movable by the soul. If, however, the intellectual soul be united to the body as its substantial form, as we have said above (1), it is impossible for another substantial form besides the intellectual soul to be found in man. In order to make this evident, we must consider that the substantial form differs from the accidental form in this, that the accidental form does not make a thing to be "simply," but to be "such," as heat does not make a thing to be simply, but only to be hot. Therefore by the coming of the accidental form a thing is not said to be made or generated simply, but to be made such, or to be in some particular condition; and in like manner, when an accidental form is removed, a thing is said to be corrupted, not simply, but relatively. Now the substantial form gives being simply; therefore by its coming a thing is said to be generated simply; and by its removal to be corrupted simply. For this reason, the old natural philosophers, who held that primary matter was some actual being--for instance, fire or air, or something of that sort--maintained that nothing is generated simply, or corrupted simply; and stated that "every becoming is nothing but an alteration," as we read, Phys. i, 4. Therefore, if besides the intellectual soul there pre-existed in matter another substantial form by which the subject of the soul were made an actual being, it would follow that the soul does not give being simply; and consequently that it is not the substantial form: and so at the advent of the soul there would not be simple generation; nor at its removal simple corruption, all of which is clearly false. Whence we must conclude, that there is no other substantial form in man besides the intellectual soul; and that the soul, as it virtually contains the sensitive and nutritive souls, so does it virtually contain all inferior forms, and itself alone does whatever the imperfect forms do in other things. The same is to be said of the sensitive soul in brute animals, and of the nutritive soul in plants, and universally of all more perfect forms with regard to the imperfect. ||

Et similiter dicitur quod anima est actus corporis etc., quia per animam et est corpus, et est organicum, et est potentia vitam habens. Sed actus primus dicitur in potentia respectu actus secundi, qui est operatio. Talis enim potentia est non abiiciens, idest non excludens, animam.||Reply to Objection 1. Aristotle does not say that the soul is the act of a body only, but "the act of a physical organic body which has life potentially"; and that this potentiality "does not reject the soul." Whence it is clear that when the soul is called the act, the soul itself is included; as when we say that heat is the act of what is hot, and light of what is lucid; not as though lucid and light were two separate things, but because a thing is made lucid by the light. In like manner, the soul is said to be the "act of a body," etc., because by the soul it is a body, and is organic, and has life potentially. Yet the first act is said to be in potentiality to the second act, which is operation; for such a potentiality "does not reject"--that is, does not exclude--the soul. ||

The soul does not move the body by its essence, as the form of the body, but by the motive power, the act of which presupposes the body to be already actualized by the soul: so that the soul by its motive power is the part which moves; and the animate body is the part moved. ||

-||<b>Iª q. 76 a. 4 ad 4 </b>Ad quartum dicendum quod Avicenna posuit formas substantiales elementorum integras remanere in mixto, mixtionem autem fieri secundum quod contrariae qualitates elementorum reducuntur ad medium. Sed hoc est impossibile. Quia diversae formae elementorum non possunt esse nisi in diversis partibus materiae; ad quarum diversitatem oportet intelligi dimensiones, sine quibus materia divisibilis esse non potest. Materia autem dimensioni subiecta non invenitur nisi in corpore. Diversa autem corpora non possunt esse in eodem loco. Unde sequitur quod elementa sint in mixto distincta secundum situm. Et ita non erit vera mixtio, quae est secundum totum, sed mixtio ad sensum, quae est secundum minima iuxta se posita. Averroes autem posuit, in III de caelo, quod formae elementorum, propter sui imperfectionem, sunt mediae inter formas accidentales et substantiales; et ideo recipiunt magis et minus; et ideo remittuntur in mixtione et ad medium reducuntur, et conflatur ex eis una forma. Sed hoc est etiam magis impossibile. Nam esse substantiale cuiuslibet rei in indivisibili consistit; et omnis additio et subtractio variat speciem, sicut in numeris, ut dicitur in VIII Metaphys. Unde impossibile est quod forma substantialis quaecumque recipiat magis et minus. Nec minus est impossibile aliquid esse medium inter substantiam et accidens. Et ideo dicendum est, secundum philosophum in I de Generat., quod formae elementorum manent in mixto non actu, sed virtute. Manent enim qualitates propriae elementorum, licet remissae, in quibus est virtus formarum elementarium. Et huiusmodi qualitas mixtionis est propria dispositio ad formam substantialem corporis mixti, puta formam lapidis, vel animae cuiuscumque.||Reply to Objection 4. Avicenna held that the substantial forms of the elements remain entire in the mixed body; and that the mixture is made by the contrary qualities of the elements being reduced to an average. But this is impossible, because the various forms of the elements must necessarily be in various parts of matter; for the distinction of which we must suppose dimensions, without which matter cannot be divisible. Now matter subject to dimension is not to be found except in a body. But various bodies cannot be in the same place. Whence it follows that elements in the mixed body would be distinct as to situation. And then there would not be a real mixture which is in respect of the whole; but only a mixture apparent to sense, by the juxtaposition of particles. Averroes maintained that the forms of elements, by reason of their imperfection, are a medium between accidental and substantial forms, and so can be "more" or "less"; and therefore in the mixture they are modified and reduced to an average, so that one form emerges from them. But this is even still more impossible. For the substantial being of each thing consists in something indivisible, and every addition and subtraction varies the species, as in numbers, as stated in Metaph. viii (Did. vii, 3); and consequently it is impossible for any substantial form to receive "more" or "less." Nor is it less impossible for anything to be a medium between substance and accident. Therefore we must say, in accordance with the Philosopher (De Gener. i, 10), that the forms of the elements remain in the mixed body, not actually but virtually. For the proper qualities of the elements remain, though modified; and in them is the power of the elementary forms. This quality of the mixture is the proper disposition for the substantial form of the mixed body; for instance, the form of a stone, or of any sort of soul. ||

Nom. Natura autem nulli deest in necessariis, unde oportuit quod anima intellectiva non solum haberet virtutem intelligendi, sed etiam virtutem sentiendi. Actio autem sensus non fit sine corporeo instrumento. Oportuit igitur animam intellectivam tali corpori uniri, quod possit esse conveniens organum sensus. Omnes autem alii sensus fundantur supra tactum. Ad organum autem tactus requiritur quod sit medium inter contraria, quae sunt calidum et frigidum, humidum et siccum, et similia, quorum est tactus apprehensivus, sic enim est in potentia ad contraria, et potest ea sentire. Unde quanto organum tactus fuerit magis reductum ad aequalitatem complexionis, tanto perceptibilior erit tactus. Anima autem intellectiva habet completissime virtutem sensitivam, quia quod est inferioris praeexistit perfectius in superiori ut dicit Dionysius in libro de Div. Nom. Unde oportuit corpus cui unitur anima intellectiva, esse corpus mixtum, inter omnia alia magis reductum ad aequalitatem complexionis. Et propter hoc homo inter omnia animalia melioris est tactus. Et inter ipsos homines, qui sunt melioris tactus, sunt melioris intellectus. Cuius signum est, quod molles carne bene aptos mente videmus, ut dicitur in II de anima.||I answer that, Since the form is not for the matter, but rather the matter for the form, we must gather from the form the reason why the matter is such as it is; and not conversely. Now the intellectual soul, as we have seen above (55, 2) in the order of nature, holds the lowest place among intellectual substances; inasmuch as it is not naturally gifted with the knowledge of truth, as the angels are; but has to gather knowledge from individual things by way of the senses, as Dionysius says (Div. Nom. vii). But nature never fails in necessary things: therefore the intellectual soul had to be endowed not only with the power of understanding, but also with the power of feeling. Now the action of the senses is not performed without a corporeal instrument. Therefore it behooved the intellectual soul to be united to a body fitted to be a convenient organ of sense. Now all the other senses are based on the sense of touch. But the organ of touch requires to be a medium between contraries, such as hot and cold, wet and dry, and the like, of which the sense of touch has the perception; thus it is in potentiality with regard to contraries, and is able to perceive them. Therefore the more the organ of touch is reduced to an equable complexion, the more sensitive will be the touch. But the intellectual soul has the power of sense in all its completeness; because what belongs to the inferior nature pre-exists more perfectly in the superior, as Dionysius says (Div. Nom. v). Therefore the body to which the intellectual soul is united should be a mixed body, above others reduced to the most equable complexion. For this reason among animals, man has the best sense of touch. And among men, those who have the best sense of touch have the best intelligence. A sign of which is that we observe "those who are refined in body are well endowed in mind," as stated in De Anima ii, 9. ||

Sed haec responsio non videtur sufficiens, quia corpus hominis ante peccatum immortale fuit non per naturam, sed per gratiae divinae donum; alioquin immortalitas eius per peccatum sublata non esset, sicut nec immortalitas Daemonis. Et ideo aliter dicendum est, quod in materia duplex conditio invenitur, una quae eligitur ad hoc quod sit conveniens formae; alia quae ex necessitate consequitur prioris dispositionis. Sicut artifex ad formam serrae eligit materiam ferream, aptam ad secandum dura; sed quod dentes serrae hebetari possint et rubiginem contrahere, sequitur ex necessitate materiae. Sic igitur et animae intellectivae debetur corpus quod sit aequalis complexionis, ex hoc autem de necessitate materiae sequitur quod sit corruptibile. Si quis vero dicat quod Deus potuit hanc necessitatem vitare, dicendum est quod in constitutione rerum naturalium non consideratur quid Deus facere possit, sed quid naturae rerum conveniat, ut Augustinus dicit, II super Gen. ad Litt. Providit tamen Deus adhibendo remedium contra mortem per gratiae donum.||Reply to Objection 1. Perhaps someone might attempt to answer this by saying that before sin the human body was incorruptible. This answer does not seem sufficient; because before sin the human body was immortal not by nature, but by a gift of Divine grace; otherwise its immortality would not be forfeited through sin, as neither was the immortality of the devil. Therefore we answer otherwise by observing that in matter two conditions are to be found; one which is chosen in order that the matter be suitable to the form; the other which follows by force of the first disposition. The artisan, for instance, for the form of the saw chooses iron adapted for cutting through hard material; but that the teeth of the saw may become blunt and rusted, follows by force of the matter itself. So the intellectual soul requires a body of equable complexion, which, however, is corruptible by force of its matter. If, however, it be said that God could avoid this, we answer that in the formation of natural things we do not consider what God might do; but what is suitable to the nature of things, as Augustine says (Gen. ad lit. ii, 1). God, however, provided in this case by applying a remedy against death in the gift of grace. ||

Et ideo oportuit animam intellectivam tali corpori uniri, et non simplici elemento, vel corpori mixto in quo excederet ignis secundum quantitatem, quia non posset esse aequalitas complexionis, propter excedentem ignis activam virtutem. Habet autem hoc corpus aequaliter complexionatum quandam dignitatem, per hoc quod est remotum a contrariis; in quo quodammodo assimilatur corpori caelesti.||Reply to Objection 2. A body is not necessary to the intellectual soul by reason of its intellectual operation considered as such; but on account of the sensitive power, which requires an organ of equable temperament. Therefore the intellectual soul had to be united to such a body, and not to a simple element, or to a mixed body, in which fire was in excess; because otherwise there could not be an equability of temperament. And this body of an equable temperament has a dignity of its own by reason of its being remote from contraries, thereby resembling in a way a heavenly body. ||

Et hoc competit animae intellectivae, quae quamvis sit una secundum essentiam, tamen propter sui perfectionem est multiplex in virtute; et ideo, ad diversas operationes, indiget diversis dispositionibus in partibus corporis cui unitur. Et propter hoc videmus quod maior est diversitas partium in animalibus perfectis quam in imperfectis, et in his quam in plantis.||Reply to Objection 3. The parts of an animal, for instance, the eye, hand, flesh, and bones, and so forth, do not make the species; but the whole does, and therefore, properly speaking, we cannot say that these are of different species, but that they are of various dispositions. This is suitable to the intellectual soul, which, although it be one in its essence, yet on account of its perfection, is manifold in power: and therefore, for its various operations it requires various dispositions in the parts of the body to which it is united. For this reason we observe that there is a greater variety of parts in perfect than in imperfect animals; and in these a greater variety than in plants. ||

Et ideo non potuerunt sibi determinari a natura vel determinatae existimationes naturales, vel etiam determinata auxilia vel defensionum vel tegumentorum; sicut aliis animalibus, quorum animae habent apprehensionem et virtutem ad aliqua particularia determinata. Sed loco horum omnium, homo habet naturaliter rationem, et manus, quae sunt organa organorum, quia per eas homo potest sibi praeparare instrumenta infinitorum modorum, et ad infinitos effectus.||Reply to Objection 4. The intellectual soul as comprehending universals, has a power extending to the infinite; therefore it cannot be limited by nature to certain fixed natural notions, or even to certain fixed means whether of defence or of clothing, as is the case with other animals, the souls of which are endowed with knowledge and power in regard to fixed particular things. Instead of all these, man has by nature his reason and his hands, which are "the organs of organs" (De Anima iii), since by their means man can make for himself instruments of an infinite variety, and for any number of purposes. ||

It would seem that the intellectual soul is united to the body through the medium of accidental dispositions. For every form exists in its proper disposed matter.

-||<b>Iª q. 76 a. 6 co. </b>Respondeo dicendum quod, si anima uniretur corpori solum ut motor, nihil prohiberet, immo magis necessarium esset esse aliquas dispositiones medias inter animam et corpus, potentiam scilicet ex parte animae, per quam moveret corpus; et aliquam habilitatem ex parte corporis, per quam corpus esset ab anima mobile. Sed si anima intellectiva unitur corpori ut forma substantialis, sicut iam supra dictum est, impossibile est quod aliqua dispositio accidentalis cadat media inter corpus et animam, vel inter quamcumque formam substantialem et materiam suam. Et huius ratio est quia, cum materia sit in potentia ad omnes actus ordine quodam, oportet quod id quod est primum simpliciter in actibus, primo in materia intelligatur. Primum autem inter omnes actus est esse. Impossibile est ergo intelligere materiam prius esse calidam vel quantam, quam esse in actu. Esse autem in actu habet per formam substantialem, quae facit esse simpliciter, ut iam dictum est. Unde impossibile est quod quaecumque dispositiones accidentales praeexistant in materia ante formam substantialem; et per consequens neque ante animam.||I answer that, If the soul were united to the body, merely as a motor, there would be nothing to prevent the existence of certain dispositions mediating between the soul and the body; on the contrary, they would be necessary, for on the part of the soul would be required the power to move the body; and on the part of the body, a certain aptitude to be moved by the soul. If, however, the intellectual soul is united to the body as the substantial form, as we have already said above (1), it is impossible for any accidental disposition to come between the body and the soul, or between any substantial form whatever and its matter. The reason is because since matter is in potentiality to all manner of acts in a certain order, what is absolutely first among the acts must be understood as being first in matter. Now the first among all acts is existence. Therefore, it is impossible for matter to be apprehended as hot, or as having quantity, before it is actual. But matter has actual existence by the substantial form, which makes it to exist absolutely, as we have said above (4). Wherefore it is impossible for any accidental dispositions to pre-exist in matter before the substantial form, and consequently before the soul. ||

Et ideo una et eadem existens, perficit materiam secundum diversos perfectionis gradus. Una enim et eadem forma est per essentiam, per quam homo est ens actu, et per quam est corpus, et per quam est vivum, et per quam est animal, et per quam est homo. Manifestum est autem quod unumquodque genus consequuntur propria accidentia. Sicut ergo materia praeintelligitur perfecta secundum esse ante intellectum corporeitatis, et sic de aliis; ita praeintelliguntur accidentia quae sunt propria entis, ante corporeitatem. Et sic praeintelliguntur dispositiones in materia ante formam, non quantum ad omnem eius effectum, sed quantum ad posteriorem.||Reply to Objection 1. As appears from what has been already said (4), the more perfect form virtually contains whatever belongs to the inferior forms; therefore while remaining one and the same, it perfects matter according to the various degrees of perfection. For the same essential form makes man an actual being, a body, a living being, an animal, and a man. Now it is clear that to every "genus" follow its own proper accidents. Therefore as matter is apprehended as perfected in its existence, before it is understood as corporeal, and so on; so those accidents which belong to existence are understood to exist before corporeity; and thus dispositions are understood in matter before the form, not as regards all its effects, but as regards the subsequent effect. ||

Quamvis enim eadem forma sit secundum essentiam quae diversos perfectionis gradus materiae attribuit, ut dictum est; tamen secundum considerationem rationis differt.||Reply to Objection 2. Dimensions of quantity are accidents consequent to the corporeity which belongs to the whole matter. Wherefore matter, once understood as corporeal and measurable, can be understood as distinct in its various parts, and as receptive of different forms according to the further degrees of perfection. For although it is essentially the same form which gives matter the various degrees of perfection, as we have said (ad 1), yet it is considered as different when brought under the observation of reason. ||

For Augustine says (Gen. ad lit. vii, 19), that "the soul administers the body by light," that is, by fire, "and by air, which is most akin to a spirit." But fire and air are bodies.

Further, things which are very distant from one another, are not united except by something between them. But the intellectual soul is very distant from the body, both because it is incorporeal, and because it is incorruptible.

Si vero anima unitur corpori ut forma, sicut iam dictum est, impossibile est quod uniatur ei aliquo corpore mediante. Cuius ratio est, quia sic dicitur aliquid unum, quomodo et ens. Forma autem per seipsam facit rem esse in actu, cum per essentiam suam sit actus; nec dat esse per aliquod medium. Unde unitas rei compositae ex materia et forma est per ipsam formam, quae secundum seipsam unitur materiae ut actus eius. Nec est aliquid aliud uniens nisi agens, quod facit materiam esse in actu, ut dicitur in VIII Metaphys. Unde patet esse falsas opiniones eorum qui posuerunt aliqua corpora esse media inter animam et corpus hominis. Quorum quidam Platonici dixerunt quod anima intellectiva habet corpus incorruptibile sibi naturaliter unitum, a quo nunquam separatur, et eo mediante unitur corpori hominis corruptibili. Quidam vero dixerunt quod unitur corpori mediante spiritu corporeo. Alii vero dixerunt quod unitur corpori mediante luce, quam dicunt esse corpus, et de natura quintae essentiae, ita quod anima vegetabilis unitur corpori mediante luce caeli siderei; anima vero sensibilis, mediante luce caeli crystallini; anima vero intellectualis, mediante luce caeli Empyrei. Quod fictitium et derisibile apparet, tum quia lux non est corpus; tum quia quinta essentia non venit materialiter in compositionem corporis mixti, cum sit inalterabilis, sed virtualiter tantum; tum etiam quia anima immediate corpori unitur ut forma materiae.||I answer that, If the soul, according to the Platonists, were united to the body merely as a motor, it would be right to say that some other bodies must intervene between the soul and body of man, or any animal whatever; for a motor naturally moves what is distant from it by means of something nearer. If, however, the soul is united to the body as its form, as we have said (1), it is impossible for it to be united by means of another body. The reason of this is that a thing is one, according as it is a being. Now the form, through itself, makes a thing to be actual since it is itself essentially an act; nor does it give existence by means of something else. Wherefore the unity of a thing composed of matter and form, is by virtue of the form itself, which by reason of its very nature is united to matter as its act. Nor is there any other cause of union except the agent, which causes matter to be in act, as the Philosopher says, Metaph. viii (Did. vii, 6). From this it is clear how false are the opinions of those who maintained the existence of some mediate bodies between the soul and body of man. Of these certain Platonists said that the intellectual soul has an incorruptible body naturally united to it, from which it is never separated, and by means of which it is united to the corruptible body of man. Others said that the soul is united to the body by means of a corporeal spirit. Others said it is united to the body by means of light, which, they say, is a body and of the nature of the fifth essence; so that the vegetative soul would be united to the body by means of the light of the sidereal heaven; the sensible soul, by means of the light of the crystal heaven; and the intellectual soul by means of the light of the empyrean heaven. Now all this is fictious and ridiculous: for light is not a body; and the fifth essence does not enter materially into the composition of a mixed body (since it is unchangeable), but only virtually: and lastly, because the soul is immediately united to the body as the form to matter. ||

Augustine speaks there of the soul as it moves the body; whence he uses the word "administration." It is true that it moves the grosser parts of the body by the more subtle parts.

The soul is indeed very distant from the body, if we consider the condition of each separately: so that if each had a separate existence, many means of connection would have to intervene. But inasmuch as the soul is the form of the body, it has not an existence apart from the existence of the body, but by its own existence is united to the body immediately. This is the case with every form which, if considered as an act, is very distant from matter, which is a being only in potentiality. ||

Further, the Philosopher says (De Anima. ii, 1) that the relation of a part of the soul to a part of the body, such as the sight to the pupil of the eye, is the same as the relation of the soul to the whole body of an animal.

-||<b>Iª q. 76 a. 8 co. </b>Respondeo dicendum quod, sicut in aliis iam dictum est, si anima uniretur corpori solum ut motor, posset dici quod non esset in qualibet parte corporis, sed in una tantum, per quam alias moveret. Sed quia anima unitur corpori ut forma, necesse est quod sit in toto, et in qualibet parte corporis. Non enim est forma corporis accidentalis, sed substantialis. Substantialis autem forma non solum est perfectio totius, sed cuiuslibet partis. Cum enim totum consistat ex partibus, forma totius quae non dat esse singulis partibus corporis, est forma quae est compositio et ordo, sicut forma domus, et talis forma est accidentalis. Anima vero est forma substantialis, unde oportet quod sit forma et actus non solum totius, sed cuiuslibet partis. Et ideo, recedente anima, sicut non dicitur animal et homo nisi aequivoce, quemadmodum et animal pictum vel lapideum; ita est de manu et oculo, aut carne et osse, ut philosophus dicit. Cuius signum est, quod nulla pars corporis habet proprium opus, anima recedente, cum tamen omne quod retinet speciem, retineat operationem speciei. Actus autem est in eo cuius est actus. Unde oportet animam esse in toto corpore, et in qualibet eius parte. Et quod tota sit in qualibet parte eius, hinc considerari potest, quia, cum totum sit quod dividitur in partes, secundum triplicem divisionem est triplex totalitas. Est enim quoddam totum quod dividitur in partes quantitativas, sicut tota linea vel totum corpus. Est etiam quoddam totum quod dividitur in partes rationis et essentiae; sicut definitum in partes definitionis, et compositum resolvitur in materiam et formam. Tertium autem totum est potentiale, quod dividitur in partes virtutis. Primus autem totalitatis modus non convenit formis, nisi forte per accidens; et illis solis formis, quae habent indifferentem habitudinem ad totum quantitativum et partes eius. Sicut albedo, quantum est de sui ratione, aequaliter se habet ut sit in tota superficie et in qualibet superficiei parte; et ideo, divisa superficie, dividitur albedo per accidens. Sed forma quae requirit diversitatem in partibus, sicut est anima, et praecipue animalium perfectorum, non aequaliter se habet ad totum et partes, unde non dividitur per accidens per divisionem quantitatis. Sic ergo totalitas quantitativa non potest attribui animae nec per se nec per accidens. Sed totalitas secunda, quae attenditur secundum rationis et essentiae perfectionem, proprie et per se convenit formis. Similiter autem et totalitas virtutis, quia forma est operationis principium. Si ergo quaereretur de albedine, utrum esset tota in tota superficie et in qualibet eius parte, distinguere oporteret. Quia si fiat mentio de totalitate quantitativa, quam habet albedo per accidens, non tota esset in qualibet parte superficiei. Et similiter dicendum est de totalitate virtutis magis enim potest movere visum albedo quae est in tota superficie, quam albedo quae est in aliqua eius particula. Sed si fiat mentio de totalitate speciei et essentiae, tota albedo est in qualibet superficiei parte. Sed quia anima totalitatem quantitativam non habet, nec per se nec per accidens, ut dictum est; sufficit dicere quod anima tota est in qualibet parte corporis secundum totalitatem perfectionis et essentiae; non autem secundum totalitatem virtutis. Quia non secundum quamlibet suam potentiam est in qualibet parte corporis; sed secundum visum in oculo, secundum auditum in aure, et sic de aliis. Tamen attendendum est quod, quia anima requirit diversitatem in partibus, non eodem modo comparatur ad totum et ad partes, sed ad totum quidem primo et per se, sicut ad proprium et proportionatum perfectibile; ad partes autem per posterius, secundum quod habent ordinem ad totum.||I answer that, As we have said, if the soul were united to the body merely as its motor, we might say that it is not in each part of the body, but only in one part through which it would move the others. But since the soul is united to the body as its form, it must necessarily be in the whole body, and in each part thereof. For it is not an accidental form, but the substantial form of the body. Now the substantial form perfects not only the whole, but each part of the whole. For since a whole consists of parts, a form of the whole which does not give existence to each of the parts of the body, is a form consisting in composition and order, such as the form of a house; and such a form is accidental. But the soul is a substantial form; and therefore it must be the form and the act, not only of the whole, but also of each part. Therefore, on the withdrawal of the soul, as we do not speak of an animal or a man unless equivocally, as we speak of a painted animal or a stone animal; so is it with the hand, the eye, the flesh and bones, as the Philosopher says (De Anima ii, 1). A proof of which is, that on the withdrawal of the soul, no part of the body retains its proper action; although that which retains its species, retains the action of the species. But act is in that which it actuates: wherefore the soul must be in the whole body, and in each part thereof. That it is entire in each part thereof, may be concluded from this, that since a whole is that which is divided into parts, there are three kinds of totality, corresponding to three kinds of division. There is a whole which is divided into parts of quantity, as a whole line, or a whole body. There is also a whole which is divided into logical and essential parts: as a thing defined is divided into the parts of a definition, and a composite into matter and form. There is, further, a third kind of whole which is potential, divided into virtual parts. The first kind of totality does not apply to forms, except perhaps accidentally; and then only to those forms, which have an indifferent relationship to a quantitative whole and its parts; as whiteness, as far as its essence is concerned, is equally disposed to be in the whole surface and in each part of the surface; and, therefore, the surface being divided, the whiteness is accidentally divided. But a form which requires variety in the parts, such as a soul, and specially the soul of perfect animals, is not equally related to the whole and the parts: hence it is not divided accidentally when the whole is divided. So therefore quantitative totality cannot be attributed to the soul, either essentially or accidentally. But the second kind of totality, which depends on logical and essential perfection, properly and essentially belongs to forms: and likewise the virtual totality, because a form is the principle of operation. Therefore if it be asked whether the whole whiteness is in the whole surface and in each part thereof, it is necessary to distinguish. If we mean quantitative totality which whiteness has accidentally, then the whole whiteness is not in each part of the surface. The same is to be said of totality of power: since the whiteness which is in the whole surface moves the sight more than the whiteness which is in a small part thereof. But if we mean totality of species and essence, then the whole whiteness is in each part of a surface. Since, however, the soul has not quantitative totality, neither essentially, nor accidentally, as we have seen; it is enough to say that the whole soul is in each part of the body, by totality of perfection and of essence, but not by totality of power. For it is not in each part of the body, with regard to each of its powers; but with regard to sight, it is in the eye; and with regard to hearing, it is in the ear; and so forth. We must observe, however, that since the soul requires variety of parts, its relation to the whole is not the same as its relation to the parts; for to the whole it is compared primarily and essentially, as to its proper and proportionate perfectible; but to the parts, secondarily, inasmuch as they are ordained to the whole. ||

Thus the soul is not in a part. Whence it does not follow that a part of an animal is an animal. ||

-||<b>Iª q. 76 a. 8 ad 4 </b>Ad quartum dicendum quod potentiarum animae quaedam sunt in ea secundum quod excedit totam corporis capacitatem, scilicet intellectus et voluntas, unde huiusmodi potentiae in nulla parte corporis esse dicuntur. Aliae vero potentiae sunt communes animae et corpori, unde talium potentiarum non oportet quod quaelibet sit in quocumque est anima; sed solum in illa parte corporis quae est proportionata ad talis potentiae operationem.||Reply to Objection 4. Some of the powers of the soul are in it according as it exceeds the entire capacity of the body, namely the intellect and the will; whence these powers are not said to be in any part of the body. Other powers are common to the soul and body; wherefore each of these powers need not be wherever the soul is, but only in that part of the body, which is adapted to the operation of such a power. ||

Quae enim est principalioris potentiae organum, est principalior pars corporis, vel quae etiam eidem potentiae principalius deservit.||Reply to Objection 5. One part of the body is said to be nobler than another, on account of the various powers, of which the parts of the body are the organs. For that part which is the organ of a nobler power, is a nobler part of the body: as also is that part which serves the same power in a nobler manner. ||
