Articulus 10 Article 10 Utrum Deus cognoscat mala Whether God knows evil things? Ad decimum sic proceditur. Videtur quod Deus non cognoscat mala. Dicit enim Philosophus, in III De Anima, quod intellectus qui non est in potentia, non cognoscit privationem. Sed malum est privatio boni, ut dicit Augustinus. Igitur, cum intellectus Dei nunquam sit in potentia, sed semper actu, ut ex dictis patet, videtur quod Deus non cognoscat mala. Objection 1: It seems that God does not know evil things. For the Philosopher (De Anima iii) says that the intellect which is not in potentiality does not know privation. But evil is the privation of good, as Augustine says (Confess. iii, 7). Therefore, as the intellect of God is never in potentiality, but is always in act, as is clear from the foregoing (A. 2), it seems that God does not know evil things. Praeterea, omnis scientia vel est causa sciti, vel causatur ab eo. Sed scientia Dei non est causa mali, nec causatur a malo. Ergo scientia Dei non est malorum. Obj. 2: Further, all knowledge is either the cause of the thing known, or is caused by it. But the knowledge of God is not the cause of evil, nor is it caused by evil. Therefore God does not know evil things. Praeterea, omne quod cognoscitur, cognoscitur per suam similitudinem, vel per suum oppositum. Quidquid autem cognoscit Deus, cognoscit per suam essentiam, ut ex dictis patet. Divina autem essentia neque est similitudo mali, neque ei malum opponitur, divinae enim essentiae nihil est contrarium, ut dicit Augustinus, XII de Civ. Dei. Ergo Deus non cognoscit mala. Obj. 3: Further, everything known is known either by its likeness, or by its opposite. But whatever God knows, He knows through His essence, as is clear from the foregoing (A. 5). Now the divine essence neither is the likeness of evil, nor is evil contrary to it; for to the divine essence there is no contrary, as Augustine says (De Civ. Dei xii). Therefore God does not know evil things. Praeterea, quod cognoscitur non per seipsum, sed per aliud, imperfecte cognoscitur. Sed malum non cognoscitur a Deo per seipsum, quia sic oporteret quod malum esset in Deo; oportet enim cognitum esse in cognoscente. Si ergo cognoscitur per aliud, scilicet per bonum, imperfecte cognoscetur ab ipso, quod est impossibile, quia nulla cognitio Dei est imperfecta. Ergo scientia Dei non est malorum. Obj. 4: Further, what is known through another and not through itself, is imperfectly known. But evil is not known by God; for the thing known must be in the knower. Therefore if evil is known through another, namely, through good, it would be known by Him imperfectly; which cannot be, for the knowledge of God is not imperfect. Therefore God does not know evil things. Sed contra est quod dicitur Proverb. XV, Infernus et perditio coram Deo. On the contrary, It is written (Prov 15:11), Hell and destruction are before God. Respondeo dicendum quod quicumque perfecte cognoscit aliquid, oportet quod cognoscat omnia quae possunt illi accidere. Sunt autem quaedam bona, quibus accidere potest ut per mala corrumpantur. Unde Deus non perfecte cognosceret bona, nisi etiam cognosceret mala. Sic autem est cognoscibile unumquodque, secundum quod est. Unde, cum hoc sit esse mali, quod est privatio boni, per hoc ipsum quod Deus cognoscit bona, cognoscit etiam mala; sicut per lucem cognoscuntur tenebrae. Unde dicit Dionysius, VII cap. de Div. Nom., quod Deus per semetipsum tenebrarum accipit visionem, non aliunde videns tenebras quam a lumine. I answer that, Whoever knows a thing perfectly, must know all that can be accidental to it. Now there are some good things to which corruption by evil may be accidental. Hence God would not know good things perfectly, unless He also knew evil things. Now a thing is knowable in the degree in which it is; hence since this is the essence of evil that it is the privation of good, by the fact that God knows good things, He knows evil things also; as by light is known darkness. Hence Dionysius says (Div. Nom. vii): God through Himself receives the vision of darkness, not otherwise seeing darkness except through light. Ad primum ergo dicendum quod verbum philosophi est sic intelligendum, quod intellectus qui non est in potentia, non cognoscit privationem per privationem in ipso existentem. Et hoc congruit cum eo quod supra dixerat, quod punctum et omne indivisibile per privationem divisionis cognoscitur. Quod contingit ex hoc, quia formae simplices et indivisibiles non sunt actu in intellectu nostro, sed in potentia tantum, nam si essent actu in intellectu nostro, non per privationem cognoscerentur. Et sic cognoscuntur simplicia a substantiis separatis. Deus igitur non cognoscit malum per privationem in se existentem, sed per bonum oppositum. Reply Obj. 1: The saying of the Philosopher must be understood as meaning that the intellect which is not in potentiality, does not know privation by privation existing in it; and this agrees with what he said previously, that a point and every indivisible thing are known by privation of division. This is because simple and indivisible forms are in our intellect not actually, but only potentially; for were they actually in our intellect, they would not be known by privation. It is thus that simple things are known by separate substances. God therefore knows evil, not by privation existing in Himself, but by the opposite good. Ad secundum dicendum quod scientia Dei non est causa mali, sed est causa boni, per quod cognoscitur malum. Reply Obj. 2: The knowledge of God is not the cause of evil; but is the cause of the good whereby evil is known. Ad tertium dicendum quod, licet malum non opponatur essentiae divinae, quae non est corruptibilis per malum, opponitur tamen effectibus Dei; quos per essentiam suam cognoscit, et eos cognoscens, mala opposita cognoscit. Reply Obj. 3: Although evil is not opposed to the divine essence, which is not corruptible by evil, it is opposed to the effects of God, which He knows by His essence; and knowing them, He knows the opposite evils. Ad quartum dicendum quod cognoscere aliquid per aliud tantum, est imperfectae cognitionis, si illud sit cognoscibile per se. Sed malum non est per se cognoscibile, quia de ratione mali est, quod sit privatio boni. Et sic neque definiri, neque cognosci potest, nisi per bonum. Reply Obj. 4: To know a thing by something else only, belongs to imperfect knowledge, if that thing is of itself knowable; but evil is not of itself knowable, forasmuch as the very nature of evil means the privation of good; therefore evil can neither be defined nor known except by good. Articulus 11 Article 11 Utrum Deus cognoscat singularia Whether God knows singular things? Ad undecimum sic proceditur. Videtur quod Deus non cognoscat singularia. Intellectus enim divinus immaterialior est quam intellectus humanus. Sed intellectus humanus, propter suam immaterialitatem, non cognoscit singularia, sed, sicut dicitur in II De Anima, ratio est universalium, sensus vero singularium. Ergo Deus non cognoscit singularia. Objection 1: It seems that God does not know singular things. For the divine intellect is more immaterial than the human intellect. Now the human intellect by reason of its immateriality does not know singular things; but as the Philosopher says (De Anima ii), reason has to do with universals, sense with singular things. Therefore God does not know singular things. Praeterea, illae solae virtutes in nobis sunt singularium cognoscitivae, quae recipiunt species non abstractas a materialibus conditionibus. Sed res in Deo sunt maxime abstractae ab omni materialitate. Ergo Deus non cognoscit singularia. Obj. 2: Further, in us those faculties alone know the singular, which receive the species not abstracted from material conditions. But in God things are in the highest degree abstracted from all materiality. Therefore God does not know singular things. Praeterea, omnis cognitio est per aliquam similitudinem. Sed similitudo singularium, inquantum sunt singularia, non videtur esse in Deo, quia principium singularitatis est materia, quae, cum sit ens in potentia tantum, omnino est dissimilis Deo, qui est actus purus. Non ergo Deus potest cognoscere singularia. Obj. 3: Further, all knowledge comes about through the medium of some likeness. But the likeness of singular things in so far as they are singular, does not seem to be in God; for the principle of singularity is matter, which, since it is in potentiality only, is altogether unlike God, Who is pure act. Therefore God cannot know singular things. Sed contra est quod dicitur, Proverb. XVI, omnes viae hominum patent oculis eius. On the contrary, It is written (Prov 16:2), All the ways of a man are open to His eyes. Respondeo dicendum quod Deus cognoscit singularia. Omnes enim perfectiones in creaturis inventae, in Deo praeexistunt secundum altiorem modum, ut ex dictis patet. Cognoscere autem singularia pertinet ad perfectionem nostram. Unde necesse est quod Deus singularia cognoscat. Nam et Philosophus pro inconvenienti habet, quod aliquid cognoscatur a nobis, quod non cognoscatur a Deo. Unde contra Empedoclem arguit, in I De Anima et in III Metaphys., quod accideret Deum esse insipientissimum, si discordiam ignoraret. Sed perfectiones quae in inferioribus dividuntur, in Deo simpliciter et unite existunt. Unde, licet nos per aliam potentiam cognoscamus universalia et immaterialia, et per aliam singularia et materialia; Deus tamen per suum simplicem intellectum utraque cognoscit. I answer that, God knows singular things. For all perfections found in creatures pre-exist in God in a higher way, as is clear from the foregoing (Q. 4, A. 2). Now to know singular things is part of our perfection. Hence God must know singular things. Even the Philosopher considers it incongruous that anything known by us should be unknown to God; and thus against Empedocles he argues (De Anima i and Metaph. iii) that God would be most ignorant if He did not know discord. Now the perfections which are divided among inferior beings, exist simply and unitedly in God; hence, although by one faculty we know the universal and immaterial, and by another we know singular and material things, nevertheless God knows both by His simple intellect. Sed qualiter hoc esse possit, quidam manifestare volentes, dixerunt quod Deus cognoscit singularia per causas universales, nam nihil est in aliquo singularium, quod non ex aliqua causa oriatur universali. Et ponunt exemplum, sicut si aliquis astrologus cognosceret omnes motus universales caeli, posset praenuntiare omnes eclipses futuras. Sed istud non sufficit. Quia singularia ex causis universalibus sortiuntur quasdam formas et virtutes, quae, quantumcumque ad invicem coniungantur, non individuantur nisi per materiam individualem. Unde qui cognosceret Socratem per hoc quod est albus vel Sophronisci filius, vel quidquid aliud sic dicatur, non cognosceret ipsum inquantum est hic homo. Unde secundum modum praedictum, Deus non cognosceret singularia in sua singularitate. Now some, wishing to show how this can be, said that God knows singular things by universal causes. For nothing exists in any singular thing, that does not arise from some universal cause. They give the example of an astrologer who knows all the universal movements of the heavens, and can thence foretell all eclipses that are to come. This, however, is not enough; for singular things from universal causes attain to certain forms and powers which, however they may be joined together, are not individualized except by individual matter. Hence he who knows Socrates because he is white, or because he is the son of Sophroniscus, or because of something of that kind, would not know him in so far as he is this particular man. Hence according to the aforesaid mode, God would not know singular things in their singularity. Alii vero dixerunt quod Deus cognoscit singularia, applicando causas universales ad particulares effectus. Sed hoc nihil est. Quia nullus potest applicare aliquid ad alterum, nisi illud praecognoscat, unde dicta applicatio non potest esse ratio cognoscendi particularia, sed cognitionem singularium praesupponit. On the other hand, others have said that God knows singular things by the application of universal causes to particular effects. But this will not hold, forasmuch as no one can apply a thing to another unless he first knows that thing; hence this application cannot be the reason of knowing the particular, for it presupposes the knowledge of singular things. Et ideo aliter dicendum est, quod, cum Deus sit causa rerum per suam scientiam, ut dictum est, intantum se extendit scientia Dei, inquantum se extendit eius causalitas. Unde, cum virtus activa Dei se extendat non solum ad formas, a quibus accipitur ratio universalis, sed etiam usque ad materiam, ut infra ostendetur; necesse est quod scientia Dei usque ad singularia se extendat, quae per materiam individuantur. Cum enim sciat alia a se per essentiam suam, inquantum est similitudo rerum velut principium activum earum, necesse est quod essentia sua sit principium sufficiens cognoscendi omnia quae per ipsum fiunt, non solum in universali, sed etiam in singulari. Et esset simile de scientia artificis, si esset productiva totius rei, et non formae tantum. Therefore it must be said otherwise, that, since God is the cause of things by His knowledge, as stated above (A. 8), His knowledge extends as far as His causality extends. Hence as the active power of God extends not only to forms, which are the source of universality, but also to matter, as we shall prove further on (Q. 44, A. 2), the knowledge of God must extend to singular things, which are individualized by matter. For since He knows things other than Himself by His essence, as being the likeness of things, or as their active principle, His essence must be the sufficing principle of knowing all things made by Him, not only in the universal, but also in the singular. The same would apply to the knowledge of the artificer, if it were productive of the whole thing, and not only of the form. Ad primum ergo dicendum quod intellectus noster speciem intelligibilem abstrahit a principiis individuantibus, unde species intelligibilis nostri intellectus non potest esse similitudo principiorum individualium. Et propter hoc, intellectus noster singularia non cognoscit. Sed species intelligibilis divini intellectus, quae est Dei essentia, non est immaterialis per abstractionem, sed per seipsam, principium existens omnium principiorum quae intrant rei compositionem, sive sint principia speciei, sive principia individui. Unde per eam Deus cognoscit non solum universalia, sed etiam singularia. Reply Obj. 1: Our intellect abstracts the intelligible species from the individualizing principles; hence the intelligible species in our intellect cannot be the likeness of the individual principles; and on that account our intellect does not know the singular. But the intelligible species in the divine intellect, which is the essence of God, is immaterial not by abstraction, but of itself, being the principle of all the principles which enter into the composition of things, whether principles of the species or principles of the individual; hence by it God knows not only universal, but also singular things. Ad secundum dicendum quod, quamvis species intellectus divini secundum esse suum non habeat conditiones materiales, sicut species receptae in imaginatione et sensu; tamen virtute se extendit ad immaterialia et materialia, ut dictum est. Reply Obj. 2: Although as regards the species in the divine intellect its being has no material conditions like the images received in the imagination and sense, yet its power extends to both immaterial and material things. Ad tertium dicendum quod materia, licet recedat a Dei similitudine secundum suam potentialitatem, tamen inquantum vel sic esse habet, similitudinem quandam retinet divini esse. Reply Obj. 3: Although matter as regards its potentiality recedes from likeness to God, yet, even in so far as it has being in this wise, it retains a certain likeness to the divine being. Articulus 12 Article 12 Utrum Deus possit cognoscere infinita Whether God can know infinite things? Ad duodecimum sic proceditur. Videtur quod Deus non possit cognoscere infinita. Infinitum enim, secundum quod est infinitum, est ignotum, quia infinitum est cuius quantitatem accipientibus semper est aliquid extra assumere, ut dicitur in III Physic. Augustinus etiam dicit, XII de Civ. Dei, quod quidquid scientia comprehenditur, scientis comprehensione finitur. Sed infinita non possunt finiri. Ergo non possunt scientia Dei comprehendi. Objection 1: It seems that God cannot know infinite things. For the infinite, as such, is unknown, since the infinite is that which, to those who measure it, leaves always something more to be measured, as the Philosopher says (Phys. iii). Moreover, Augustine says (De Civ. Dei xii) that whatever is comprehended by knowledge, is bounded by the comprehension of the knower. Now infinite things have no boundary. Therefore they cannot be comprehended by the knowledge of God. Si dicatur quod ea quae in se sunt infinita, scientiae Dei finita sunt, contra, ratio infiniti est quod sit impertransibile; et finiti quod sit pertransibile, ut dicitur in III Physic. Sed infinitum non potest transiri nec a finito, nec ab infinito, ut probatur in VI Physic. Ergo infinitum non potest esse finitum finito, neque etiam infinito. Et ita infinita non sunt finita scientiae Dei, quae est infinita. Obj. 2: Further, if we say that things infinite in themselves are finite in God’s knowledge, against this it may be urged that the essence of the infinite is that it is untraversable, and the finite that it is traversable, as said in Phys. iii. But the infinite is not traversable either by the finite or by the infinite, as is proved in Phys. vi. Therefore the infinite cannot be bounded by the finite, nor even by the infinite; and so the infinite cannot be finite in God’s knowledge, which is infinite. Praeterea, scientia Dei est mensura scitorum. Sed contra rationem infiniti est, quod sit mensuratum. Ergo infinita non possunt sciri a Deo. Obj. 3: Further, the knowledge of God is the measure of what is known. But it is contrary to the essence of the infinite that it be measured. Therefore infinite things cannot be known by God. Sed contra est quod dicit Augustinus, XII de Civ. Dei, quamvis infinitorum numerorum nullus sit numerus, non est tamen incomprehensibilis ei, cuius scientiae non est numerus. On the contrary, Augustine says (De Civ. Dei xii), Although we cannot number the infinite, nevertheless it can be comprehended by Him whose knowledge has no bounds. Respondeo dicendum quod, cum Deus sciat non solum ea quae sunt actu, sed etiam ea quae sunt in potentia vel sua vel creaturae, ut ostensum est; haec autem constat esse infinita; necesse est dicere quod Deus sciat infinita. Et licet scientia visionis, quae est tantum eorum quae sunt vel erunt vel fuerunt, non sit infinitorum, ut quidam dicunt, cum non ponamus mundum ab aeterno fuisse, nec generationem et motum in aeternum mansura, ut individua in infinitum multiplicentur, tamen, si diligentius consideretur, necesse est dicere quod Deus etiam scientia visionis sciat infinita. Quia Deus scit etiam cogitationes et affectiones cordium, quae in infinitum multiplicabuntur, creaturis rationalibus permanentibus absque fine. I answer that, Since God knows not only things actual but also things possible to Himself or to created things, as shown above (A. 9), and as these must be infinite, it must be held that He knows infinite things. Although the knowledge of vision which has relation only to things that are, or will be, or were, is not of infinite things, as some say, for we do not say that the world is eternal, nor that generation and movement will go on for ever, so that individuals be infinitely multiplied; yet, if we consider more attentively, we must hold that God knows infinite things even by the knowledge of vision. For God knows even the thoughts and affections of hearts, which will be multiplied to infinity as rational creatures go on for ever. Hoc autem ideo est, quia cognitio cuiuslibet cognoscentis se extendit secundum modum formae quae est principium cognitionis. Species enim sensibilis, quae est in sensu, est similitudo solum unius individui, unde per eam solum unum individuum cognosci potest. Species autem intelligibilis intellectus nostri est similitudo rei quantum ad naturam speciei, quae est participabilis a particularibus infinitis, unde intellectus noster per speciem intelligibilem hominis, cognoscit quodammodo homines infinitos. Sed tamen non inquantum distinguuntur ab invicem, sed secundum quod communicant in natura speciei; propter hoc quod species intelligibilis intellectus nostri non est similitudo hominum quantum ad principia individualia, sed solum quantum ad principia speciei. Essentia autem divina, per quam intellectus divinus intelligit, est similitudo sufficiens omnium quae sunt vel esse possunt, non solum quantum ad principia communia, sed etiam quantum ad principia propria uniuscuiusque, ut ostensum est. Unde sequitur quod scientia Dei se extendat ad infinita, etiam secundum quod sunt ab invicem distincta. The reason of this is to be found in the fact that the knowledge of every knower is measured by the mode of the form which is the principle of knowledge. For the sensible image in sense is the likeness of only one individual thing, and can give the knowledge of only one individual. But the intelligible species of our intellect is the likeness of the thing as regards its specific nature, which is participable by infinite particulars; hence our intellect by the intelligible species of man in a certain way knows infinite men; not however as distinguished from each other, but as communicating in the nature of the species; and the reason is because the intelligible species of our intellect is the likeness of man not as to the individual principles, but as to the principles of the species. On the other hand, the divine essence, whereby the divine intellect understands, is a sufficing likeness of all things that are, or can be, not only as regards the universal principles, but also as regards the principles proper to each one, as shown above. Hence it follows that the knowledge of God extends to infinite things, even as distinct from each other. Ad primum ergo dicendum quod infiniti ratio congruit quantitati, secundum philosophum in I Physic. De ratione autem quantitatis est ordo partium. Cognoscere ergo infinitum secundum modum infiniti, est cognoscere partem post partem. Et sic nullo modo contingit cognosci infinitum, quia quantacumque quantitas partium accipiatur, semper remanet aliquid extra accipientem. Deus autem non sic cognoscit infinitum vel infinita, quasi enumerando partem post partem; cum cognoscat omnia simul, non successive, ut supra dictum est. Unde nihil prohibet ipsum cognoscere infinita. Reply Obj. 1: The idea of the infinite pertains to quantity, as the Philosopher says (Phys. i). But the idea of quantity implies the order of parts. Therefore to know the infinite according to the mode of the infinite is to know part after part; and in this way the infinite cannot be known; for whatever quantity of parts be taken, there will always remain something else outside. But God does not know the infinite or infinite things as if He enumerated part after part, since He knows all things simultaneously, and not successively, as said above (A. 7). Hence there is nothing to prevent Him from knowing infinite things. Ad secundum dicendum quod transitio importat quandam successionem in partibus, et inde est quod infinitum transiri non potest, neque a finito neque ab infinito. Sed ad rationem comprehensionis sufficit adaequatio, quia id comprehendi dicitur, cuius nihil est extra comprehendentem. Unde non est contra rationem infiniti, quod comprehendatur ab infinito. Et sic, quod in se est infinitum, potest dici finitum scientiae Dei, tanquam comprehensum, non tamen tanquam pertransibile. Reply Obj. 2: Transition imports a certain succession of parts; and hence it is that the infinite cannot be traversed by the finite, nor by the infinite. But equality suffices for comprehension, because that is said to be comprehended which has nothing outside the comprehender. Hence it is not against the idea of the infinite to be comprehended by the infinite. And so, what is infinite in itself can be called finite to the knowledge of God as comprehended; but not as if it were traversable. Ad tertium dicendum quod scientia Dei est mensura rerum, non quantitativa, qua quidem mensura carent infinita; sed quia mensurat essentiam et veritatem rei. Unumquodque enim intantum habet de veritate suae naturae, inquantum imitatur Dei scientiam; sicut artificiatum inquantum concordat arti. Dato autem quod essent aliqua infinita actu secundum numerum, puta infiniti homines; vel secundum quantitatem continuam, ut si esset aer infinitus, ut quidam antiqui dixerunt, tamen manifestum est quod haberent esse determinatum et finitum, quia esse eorum esset limitatum ad aliquas determinatas naturas. Unde mensurabilia essent secundum scientiam Dei. Reply Obj. 3: The knowledge of God is the measure of things, not quantitatively, for the infinite is not subject to this kind of measure; but it is the measure of the essence and truth of things. For everything has truth of nature according to the degree in which it imitates the knowledge of God, as the thing made by art agrees with the art. Granted, however, an actually infinite number of things, for instance, an infinitude of men, or an infinitude in continuous quantity, as an infinitude of air, as some of the ancients held; yet it is manifest that these would have a determinate and finite being, because their being would be limited to some determinate nature. Hence they would be measurable as regards the knowledge of God.
