Quiddities: What Intellectual Operations Know

No. Our intellect cannot know the singular in material things directly and primarily. The reason of this is that the principle of singularity in material things is individual matter, whereas our intellect understands by abstracting the intelligible species from such matter.

Singulare in rebus materialibus intellectus noster directe et primo cognoscere non potest. Cuius ratio est, quia principium singularitatis in rebus materialibus est materia individualis, intellectus autem noster intelligit abstrahendo speciem intelligibilem ab huiusmodi materia.

The higher power can do what the lower power can, but in a more eminent way. Wherefore what the sense knows materially and concretely, which is to know the singular directly, the intellect knows immaterially and in the abstract, which is to know the universal.

Virtus superior potest illud quod potest virtus inferior, sed eminentiori modo. Unde id quod cognoscit sensus materialiter et concrete, quod est cognoscere singulare directe, hoc cognoscit intellectus immaterialiter et abstracte, quod est cognoscere universale.

Intelligibility is incompatible with the singular not as such, but as material, for nothing can be understood otherwise than immaterially. Therefore if there be an immaterial singular such as the intellect, there is no reason why it should not be intelligible.

Singulare non repugnat intelligibilitati inquantum est singulare, sed inquantum est materiale, quia nihil intelligitur nisi immaterialiter. Et ideo si sit aliquod singulare immateriale, sicut est intellectus, hoc non repugnat intelligibilitati.

Now what is abstracted from individual matter is the universal. Hence our intellect knows directly the universal only.

Quod autem a materia individuali abstrahitur, est universale. Unde intellectus noster directe non est cognoscitivus nisi universalium.

But indirectly, and as it were by a kind of reflection, it can know the singular, because, as we have said above (Q85, A7), even after abstracting the intelligible species, the intellect, in order to understand, needs to turn to the phantasms in which it understands the species, as is said De Anima iii, 7. Therefore it understands the universal directly through the intelligible species, and indirectly the singular represented by the phantasm.

Indirecte autem, et quasi per quandam reflexionem, potest cognoscere singulare, quia, sicut supra dictum est, etiam postquam species intelligibiles abstraxit, non potest secundum eas actu intelligere nisi convertendo se ad phantasmata, in quibus species intelligibiles intelligit, ut dicitur in III de anima. Sic igitur ipsum universale per speciem intelligibilem directe intelligit; indirecte autem singularia, quorum sunt phantasmata.

No. Neither actually nor habitually can our intellect know the infinite, but only potentially, because the nature of our mind is to know species abstracted from phantasms.

Nec actu nec habitu intellectus noster potest cognoscere infinita, sed in potentia tantum, quia intellectus noster natus est cognoscere species per abstractionem a phantasmatibus.

Therefore it cannot know actually or habitually species of numbers or figures that are not in the imagination, except in a general way and in their universal principles; and this is to know them potentially and confusedly.

Et ideo illas species numerorum et figurarum quas quis non est imaginatus, non potest cognoscere nec actu nec habitu, nisi forte in genere et in principiis universalibus; quod est cognoscere in potentia et confuse.

As we have said above (Q7, A1), God is called infinite, because He is a form unlimited by matter; whereas in material things, the term 'infinite' is applied to that which is deprived of any formal term. And form being known in itself, whereas matter cannot be known without form, it follows that the material infinite is in itself unknowable.

Sicut supra dictum est, Deus dicitur infinitus sicut forma quae non est terminata per aliquam materiam, in rebus autem materialibus aliquid dicitur infinitum per privationem formalis terminationis. Et quia forma secundum se nota est, materia autem sine forma ignota, inde est quod infinitum materiale est secundum se ignotum.

But the formal infinite, God, is of Himself known; but He is unknown to us by reason of our feeble intellect, which in its present state has a natural aptitude for material objects only. Therefore we cannot know God in our present life except through material effects. In the future life this defect of intellect will be removed by the state of glory, when we shall be able to see the Essence of God Himself, but without being able to comprehend Him.

Infinitum autem formale, quod est Deus, est secundum se notum, ignotum autem quoad nos, propter defectum intellectus nostri, qui secundum statum praesentis vitae habet naturalem aptitudinem ad materialia cognoscenda. Et ideo in praesenti Deum cognoscere non possumus nisi per materiales effectus. In futuro autem tolletur defectus intellectus nostri per gloriam, et tunc ipsum Deum in sua essentia videre poterimus, tamen absque comprehensione.

As our intellect is infinite in power, so does it know the infinite. For its power is indeed infinite inasmuch as it is not terminated by corporeal matter. Moreover it can know the universal, which is abstracted from individual matter, and which consequently is not limited to one individual, but, considered in itself, extends to an infinite number of individuals.

Sicut intellectus noster est infinitus virtute, ita infinitum cognoscit. Est enim virtus eius infinita, secundum quod non terminatur per materiam corporalem. Et est cognoscitivus universalis, quod est abstractum a materia individuali, et per consequens non finitur ad aliquod individuum, sed, quantum est de se, ad infinita individua se extendit.

The intelligible species enter into our intellect successively; since many things cannot be actually understood at the same time: and therefore there must be a definite and not an infinite number of species in our intellect.

Sed species intelligibiles ingrediuntur intellectum nostrum successive, quia non multa simul actu intelliguntur. Et ideo oportet numeratas, et non infinitas species esse in intellectu nostro.

Now in material things the infinite does not exist actually, but only potentially, in the sense of one succeeding another, as is said Phys. iii, 6. Therefore infinity is potentially in our mind through its considering successively one thing after another: because never does our intellect understand so many things, that it cannot understand more.

In rebus autem materialibus non invenitur infinitum in actu, sed solum in potentia, secundum quod unum succedit alteri, ut dicitur in III Physic. Et ideo in intellectu nostro invenitur infinitum in potentia, in accipiendo scilicet unum post aliud, quia nunquam intellectus noster tot intelligit, quin possit plura intelligere.

On the other hand, our intellect cannot understand the infinite either actually or habitually. Not actually, for our intellect cannot know actually at the same time, except what it knows through one species. But the infinite is not represented by one species, for if it were it would be something whole and complete.

Actu autem vel habitu non potest cognoscere infinita intellectus noster. Actu quidem non, quia intellectus noster non potest simul actu cognoscere nisi quod per unam speciem cognoscit. Infinitum autem non habet unam speciem, alioquin haberet rationem totius et perfecti.

Consequently it cannot be understood except by a successive consideration of one part after another, as is clear from its definition (Phys. iii, 6): for the infinite is that "from which, however much we may take, there always remains something to be taken." Thus the infinite could not be known actually, unless all its parts were counted: which is impossible.

Et ideo non potest intelligi nisi accipiendo partem post partem, ut ex eius definitione patet in III Physic., est enim infinitum cuius quantitatem accipientibus semper est aliquid extra accipere, et sic infinitum cognosci non posset actu, nisi omnes partes eius numerarentur, quod est impossibile.

For the same reason we cannot have habitual knowledge of the infinite: because in us habitual knowledge results from actual consideration: since by understanding we acquire knowledge, as is said Ethic. ii, 1.

Et eadem ratione non possumus intelligere infinita in habitu. In nobis enim habitualis cognitio causatur ex actuali consideratione, intelligendo enim efficimur scientes, ut dicitur in II Ethic.

Wherefore it would not be possible for us to have a habit of an infinity of things distinctly known, unless we had already considered the entire infinity thereof, counting them according to the succession of our knowledge: which is impossible.

Unde non possemus habere habitum infinitorum secundum distinctam cognitionem, nisi consideravissemus omnia infinita, numerando ea secundum cognitionis successionem, quod est impossibile.

Yes. The intellect knows contingent things because some sciences are of the contingent things, as the moral sciences, the objects of which are human actions subject to free choice, and again, the natural sciences in as far as they relate to things generated and corruptible.

Intellectus est cognoscitivus contingentium quia quaedam scientiae sunt de contingentibus, sicut scientiae morales, quae sunt de actibus humanis subiectis libero arbitrio, et etiam scientiae naturales, quantum ad partem quae tractat de generabilibus et corruptibilibus.

Contingent things can be considered in two ways; either as contingent, or as containing some element of necessity, since every contingent thing has in it something necessary: for example, that Socrates runs, is in itself contingent; but the relation of running to motion is necessary, for it is necessary that Socrates move if he runs.

Contingentia dupliciter possunt considerari. Uno modo, secundum quod contingentia sunt. Alio modo, secundum quod in eis aliquid necessitatis invenitur, nihil enim est adeo contingens, quin in se aliquid necessarium habeat. Sicut hoc ipsum quod est Socratem currere, in se quidem contingens est; sed habitudo cursus ad motum est necessaria, necessarium enim est Socratem moveri, si currit.

Now contingency arises from matter, for contingency is a potentiality to be or not to be, and potentiality belongs to matter; whereas necessity results from the aspect of form, because whatever is consequent on form is of necessity in the subject. But matter is the individualizing principle, whereas the universal aspect comes from the abstraction of the form from the particular matter.

Est autem unumquodque contingens ex parte materiae, quia contingens est quod potest esse et non esse; potentia autem pertinet ad materiam. Necessitas autem consequitur rationem formae, quia ea quae consequuntur ad formam, ex necessitate insunt. Materia autem est individuationis principium, ratio autem universalis accipitur secundum abstractionem formae a materia particulari.

Moreover it was laid down above (Q86 A1) that the intellect of itself and directly has the universal for its object; while the object of sense is the singular, which in a certain way is the indirect object of the intellect, as we have said above (Q86 A1).

Dictum autem est supra quod per se et directe intellectus est universalium; sensus autem singularium, quorum etiam indirecte quodammodo est intellectus, ut supra dictum est.

Therefore contingent things, considered as such, are known directly by sense and indirectly by the intellect, while the universal and necessary aspects of contingent things are known only by the intellect.

Sic igitur contingentia, prout sunt contingentia, cognoscuntur directe quidem sensu, indirecte autem ab intellectu, rationes autem universales et necessariae contingentium cognoscuntur per intellectum.

Hence if we consider the universal aspects of knowable things, then all science is of necessary things. But if we consider the things themselves, thus some sciences are of necessary things, some of contingent things.

Unde si attendantur rationes universales scibilium, omnes scientiae sunt de necessariis. Si autem attendantur ipsae res, sic quaedam scientia est de necessariis, quaedam vero de contingentibus.

No. It is not natural for the soul to know the future when withdrawn from the senses because it is connatural to our intellect to know things, not thus, but by receiving its knowledge from the senses.

Non est secundum naturam animae quod futura cognoscat cum a sensibus alienatur quia iste modus cognoscendi non est connaturalis intellectui nostro, sed magis ut cognitionem a sensibus accipiat.

Rather does it know the future by the impression of superior spiritual and corporeal causes; of spiritual causes, when by Divine power the human intellect is enlightened through the ministry of angels, and the phantasms are directed to the knowledge of future events; or, by the influence of demons, when the imagination is moved regarding the future known to the demons, as explained above (Q57, A3).

Sed magis per impressionem aliquarum causarum superiorum spiritualium et corporalium. Spiritualium quidem, sicut cum virtute divina ministerio Angelorum intellectus humanus illuminatur, et phantasmata ordinantur ad futura aliqua cognoscenda; vel etiam cum per operationem Daemonum fit aliqua commotio in phantasia ad praesignandum aliqua futura quae Daemones cognoscunt, ut supra dictum est.

The soul is naturally more inclined to receive these impressions of spiritual causes when it is withdrawn from the senses, as it is then nearer to the spiritual world, and freer from external distractions. The same may also come from superior corporeal causes. For it is clear that superior bodies influence inferior bodies.

Huiusmodi autem impressiones spiritualium causarum magis nata est anima humana suscipere cum a sensibus alienatur, quia per hoc propinquior fit substantiis spiritualibus, et magis libera ab exterioribus inquietudinibus. Contingit autem et hoc per impressionem superiorum causarum corporalium. Manifestum est enim quod corpora superiora imprimunt in corpora inferiora.

Hence, in consequence of the sensitive faculties being acts of corporeal organs, the influence of the heavenly bodies causes the imagination to be affected, and so, as the heavenly bodies cause many future events, the imagination receives certain images of some such events.

Unde cum vires sensitivae sint actus corporalium organorum, consequens est quod ex impressione caelestium corporum immutetur quodammodo phantasia. Unde cum caelestia corpora sint causa multorum futurorum, fiunt in imaginatione aliqua signa quorundam futurorum.

Brute animals have no power above the imagination wherewith to regulate its phantasms, as man does with formal aspect, and therefore their imagination follows entirely the influence of the heavenly bodies. Thus from such animals' movements some future things, such as rain and the like, may be known rather than from human movements directed by reason.

Animalia bruta non habent aliquid supra phantasiam quod ordinet phantasmata, sicut habent homines rationem; et ideo phantasia brutorum animalium totaliter sequitur impressionem caelestem. Et ideo ex motibus huiusmodi animalium magis possunt cognosci quaedam futura, ut pluvia et huiusmodi, quam ex motibus hominum, qui moventur per consilium rationis.

Speaking, however, of the knowledge of the future in a general way, we must observe that the future may be known in two ways: either in itself, or in its cause. The future cannot be known in itself save by God alone; to Whom even that is present which in the course of events is future, inasmuch as from eternity His glance embraces the whole course of time, as we have said above when treating of God's knowledge (Q14, A13).

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

But inasmuch as it exists in its cause, the future can be known by us also. And if, indeed, the cause be such as to have a necessary connection with its future result, then the future is known with scientific certitude, just as the astronomer foresees the future eclipse. If, however, the cause be such as to produce a certain result more frequently than not, then can the future be known more or less conjecturally, according as its cause is more or less inclined to produce the effect.

Sed prout sunt in suis causis, cognosci possunt etiam a nobis. Et si quidem in suis causis sint ut ex quibus ex necessitate proveniant, cognoscuntur per certitudinem scientiae; sicut astrologus praecognoscit eclipsim futuram. Si autem sic sint in suis causis ut ab eis proveniant ut in pluribus, sic cognosci possunt per quandam coniecturam vel magis vel minus certam, secundum quod causae sunt vel magis vel minus inclinatae ad effectus.

We must apply the same distinction to future things, as we applied above (Q86, A3) to contingent things. For future things considered as subject to time are singular, and the human intellect knows them by reflection only, as stated above (Q86, A1). But the formal aspects of future things are able to be universal, and thus perceptible by the intellect, and about them there can even be scientific knowledge.

De cognitione futurorum eodem modo distinguendum est, sicut de cognitione contingentium. Nam ipsa futura ut sub tempore cadunt, sunt singularia, quae intellectus humanus non cognoscit nisi per reflexionem, ut supra dictum est. Rationes autem futurorum possunt esse universales, et intellectu perceptibiles, et de eis etiam possunt esse scientiae.
