1 Objection 1: It seems that there are not ideas in God of all things that He knows. For the idea of evil is not in God; since it would follow that evil was in Him. But evil things are known by God. Therefore there are not ideas of all things that God knows.
1 Ad tertium sic proceditur. Videtur quod non omnium quae cognoscit Deus, sint ideae in ipso. Mali enim idea non est in Deo, quia sequeretur malum esse in Deo. Sed mala cognoscuntur a Deo. Ergo non omnium quae cognoscuntur a Deo, sunt ideae.
2 Objection 2: Further, God knows things that neither are, nor will be, nor have been, as has been said above Article 9). But of such things there are no ideas, since, as Dionysius says Div. Nom. v): Acts of the divine will are the determining and effective types of things. Therefore there are not in God ideas of all things known by Him.
2 Praeterea, Deus cognoscit ea quae nec sunt nec erunt nec fuerunt, ut supra dictum est. Sed horum non sunt ideae, quia dicit Dionysius, V cap. de Div. Nom., quod exemplaria sunt divinae voluntates, determinativae et effectivae rerum. Ergo non omnium quae a Deo cognoscuntur, sunt ideae in ipso.
3 Objection 3: Further, God knows primary matter, of which there can be no idea, since it has no form. Hence the same conclusion.
3 Praeterea, Deus cognoscit materiam primam, quae non potest habere ideam, cum nullam habeat formam. Ergo idem quod prius.
4 Objection 4: Further, it is certain that God knows not only species, but also genera, singulars, and accidents. But there are not ideas of these, according to Plato's teaching, who first taught ideas, as Augustine says Octog. Tri. Quaest. qu. xlvi). Therefore there are not ideas in God of all things known by Him.
4 Praeterea, constat quod Deus scit non solum species, sed etiam genera et singularia et accidentia. Sed horum non sunt ideae, secundum positionem Platonis, qui primus ideas introduxit, ut dicit Augustinus. Non ergo omnium cognitorum a Deo sunt ideae in ipso.
5 On the contrary, Ideas are types existing in the divine mind, as is clear from Augustine Octog. Tri. Quaest. qu. xlvi). But God has the proper types of all things that He knows; and therefore He has ideas of all things known by Him.
5 Sed contra, ideae sunt rationes in mente divina existentes, ut per Augustinum patet. Sed omnium quae cognoscit, Deus habet proprias rationes. Ergo omnium quae cognoscit, habet ideam.
6 I answer that, As ideas, according to Plato, are principles of the knowledge of things and of their generation, an idea has this twofold office, as it exists in the mind of God. So far as the idea is the principle of the making of things, it may be called an exemplar, and belongs to practical knowledge. But so far as it is a principle of knowledge, it is properly called a type, and may belong to speculative knowledge also. As an exemplar, therefore, it has respect to everything made by God in any period of time; whereas as a principle of knowledge it has respect to all things known by God, even though they never come to be in time; and to all things that He knows according to their proper type, in so far as they are known by Him in a speculative manner.
6 Respondeo dicendum quod, cum ideae a Platone ponerentur principia cognitionis rerum et generationis ipsarum, ad utrumque se habet idea, prout in mente divina ponitur. Et secundum quod est principium factionis rerum, exemplar dici potest, et ad practicam cognitionem pertinet. Secundum autem quod principium cognoscitivum est, proprie dicitur ratio; et potest etiam ad scientiam speculativam pertinere. Secundum ergo quod exemplar est, secundum hoc se habet ad omnia quae a Deo fiunt secundum aliquod tempus. Secundum vero quod principium cognoscitivum est, se habet ad omnia quae cognoscuntur a Deo, etiam si nullo tempore fiant; et ad omnia quae a Deo cognoscuntur secundum propriam rationem, et secundum quod cognoscuntur ab ipso per modum speculationis.
7 Reply to Objection 1: Evil is known by God not through its own type, but through the type of good. Evil, therefore, has no idea in God, neither in so far as an idea is an exemplar nor as a type.
7 Ad primum ergo dicendum quod malum cognoscitur a Deo non per propriam rationem, sed per rationem boni. Et ideo malum non habet in Deo ideam, neque secundum quod idea est exemplar, neque secundum quod est ratio.
8 Reply to Objection 2: God has no practical knowledge, except virtually, of things which neither are, nor will be, nor have been. Hence, with respect to these there is no idea in God in so far as idea signifies an exemplar but only in so far as it denotes a type.
8 Ad secundum dicendum quod eorum quae neque sunt neque erunt neque fuerunt, Deus non habet practicam cognitionem, nisi virtute tantum. Unde respectu eorum non est idea in Deo, secundum quod idea significat exemplar, sed solum secundum quod significat rationem.
9 Reply to Objection 3: Plato is said by some to have considered matter as not created; and therefore he postulated not an idea of matter but a concause with matter. Since, however, we hold matter to be created by God, though not apart from form, matter has its idea in God; but not apart from the idea of the composite; for matter in itself can neither exist, nor be known.
9 Ad tertium dicendum quod Plato, secundum quosdam, posuit materiam non creatam, et ideo non posuit ideam esse materiae, sed materiae concausam. Sed quia nos ponimus materiam creatam a Deo, non tamen sine forma, habet quidem materia ideam in Deo, non tamen aliam ab idea compositi. Nam materia secundum se neque esse habet, neque cognoscibilis est.
10 Reply to Objection 4: Genus can have no idea apart from the idea of species, in so far as idea denotes an exemplar; for genus cannot exist except in some species. The same is the case with those accidents that inseparably accompany their subject; for these come into being along with their subject. But accidents which supervene to the subject, have their special idea. For an architect produces through the form of the house all the accidents that originally accompany it; whereas those that are superadded to the house when completed, such as painting, or any other such thing, are produced through some other form. Now individual things, according to Plato, have no other idea than that of species; both because particular things are individualized by matter, which, as some say, he held to be uncreated and the concause with the idea; and because the intention of nature regards the species, and produces individuals only that in them the species may be preserved. However, divine providence extends not merely to species; but to individuals as will be shown later Question 22, Article 3).
10 Ad quartum dicendum quod genera non possunt habere ideam aliam ab idea speciei, secundum quod idea significat exemplar, quia nunquam genus fit nisi in aliqua specie. Similiter etiam est de accidentibus quae inseparabiliter concomitantur subiectum, quia haec simul fiunt cum subiecto. Accidentia autem quae superveniunt subiecto, specialem ideam habent. Artifex enim per formam domus facit omnia accidentia quae a principio concomitantur domum, sed ea quae superveniunt domui iam factae, ut picturae vel aliquid aliud, facit per aliquam aliam formam. Individua vero, secundum Platonem, non habebant aliam ideam quam ideam speciei, tum quia singularia individuantur per materiam, quam ponebat esse increatam, ut quidam dicunt, et concausam ideae; tum quia intentio naturae consistit in speciebus, nec particularia producit, nisi ut in eis species salventur. Sed providentia divina non solum se extendit ad species, sed ad singularia, ut infra dicetur.
