1 Objection 1: It would seem that it is not necessary that every being be created by God. For there is nothing to prevent a thing from being without that which does not belong to its essence, as a man can be found without whiteness. But the relation of the thing caused to its cause does not appear to be essential to beings, for some beings can be understood without it; therefore they can exist without it; and therefore it is possible that some beings should not be created by God.
1 Ad primum sic proceditur. Videtur quod non sit necessarium omne ens esse creatum a Deo. Nihil enim prohibet inveniri rem sine eo quod non est de ratione rei, sicut hominem sine albedine. Sed habitudo causati ad causam non videtur esse de ratione entium quia sine hac possunt aliqua entia intelligi. Ergo sine hac possunt esse. Ergo nihil prohibet esse aliqua entia non creata a Deo.
2 Objection 2: Further, a thing requires an efficient cause in order to exist. Therefore whatever cannot but exist does not require an efficient cause. But no necessary thing can not exist, because whatever necessarily exists cannot but exist. Therefore as there are many necessary things in existence, it appears that not all beings are from God.
2 Praeterea, ad hoc aliquid indiget causa efficiente, ut sit. Ergo quod non potest non esse, non indiget causa efficiente. Sed nullum necessarium potest non esse, quia quod necesse est esse, non potest non esse. Cum igitur multa sint necessaria in rebus, videtur quod non omnia entia sint a Deo.
3 Objection 3: Further, whatever things have a cause, can be demonstrated by that cause. But in mathematics demonstration is not made by the efficient cause, as appears from the Philosopher Metaph. iii, text 3); therefore not all beings are from God as from their efficient cause.
3 Praeterea, quorumcumque est aliqua causa, in his potest fieri demonstratio per causam illam. Sed in mathematicis non fit demonstratio per causam agentem, ut per philosophum patet, in III Metaphys. Non igitur omnia entia sunt a Deo sicut a causa agente.
4 On the contrary, It is said Rm. 11, 36): Of Him, and by Him, and in Him are all things.
4 Sed contra est quod dicitur Rom. XI, ex ipso, et per ipsum, et in ipso sunt omnia.
5 I answer that, It must be said that every being in any way existing is from God. For whatever is found in anything by participation, must be caused in it by that to which it belongs essentially, as iron becomes ignited by fire. Now it has been shown above Question 3, Article 4) when treating of the divine simplicity that God is the essentially self-subsisting Being; and also it was shown Question 11, Articles 3, 4) that subsisting being must be one; as, if whiteness were self-subsisting, it would be one, since whiteness is multiplied by its recipients. Therefore all beings apart from God are not their own being, but are beings by participation. Therefore it must be that all things which are diversified by the diverse participation of being, so as to be more or less perfect, are caused by one First Being, Who possesses being most perfectly. Hence Plato said Parmen. xxvi) that unity must come before multitude; and Aristotle said Metaph. ii, text 4) that whatever is greatest in being and greatest in truth, is the cause of every being and of every truth; just as whatever is the greatest in heat is the cause of all heat.
5 Respondeo dicendum quod necesse est dicere omne quod quocumque modo est, a Deo esse. Si enim aliquid invenitur in aliquo per participationem, necesse est quod causetur in ipso ab eo cui essentialiter convenit; sicut ferrum fit ignitum ab igne. Ostensum est autem supra, cum de divina simplicitate ageretur, quod Deus est ipsum esse per se subsistens. Et iterum ostensum est quod esse subsistens non potest esse nisi unum, sicut si albedo esset subsistens, non posset esse nisi una, cum albedines multiplicentur secundum recipientia. Relinquitur ergo quod omnia alia a Deo non sint suum esse, sed participant esse. Necesse est igitur omnia quae diversificantur secundum diversam participationem essendi, ut sint perfectius vel minus perfecte, causari ab uno primo ente, quod perfectissime est. Unde et Plato dixit quod necesse est ante omnem multitudinem ponere unitatem. Et Aristoteles dicit, in II Metaphys., quod id quod est maxime ens et maxime verum, est causa omnis entis et omnis veri, sicut id quod maxime calidum est, est causa omnis caliditatis.
6 Reply to Objection 1: Though the relation to its cause is not part of the definition of a thing caused, still it follows, as a consequence, on what belongs to its essence; because from the fact that a thing has being by participation, it follows that it is caused. Hence such a being cannot be without being caused, just as man cannot be without having the faculty of laughing. But, since to be caused does not enter into the essence of being as such, therefore is it possible for us to find a being uncaused.
6 Ad primum ergo dicendum quod, licet habitudo ad causam non intret definitionem entis quod est causatum, tamen sequitur ad ea qua sunt de eius ratione, quia ex hoc quod aliquid per participationem est ens, sequitur quod sit causatum ab alio. Unde huiusmodi ens non potest esse, quin sit causatum; sicut nec homo, quin sit risibile. Sed quia esse causatum non est de ratione entis simpliciter, propter hoc invenitur aliquod ens non causatum.
7 Reply to Objection 2: This objection has led some to say that what is necessary has no cause Phys. viii, text 46). But this is manifestly false in the demonstrative sciences, where necessary principles are the causes of necessary conclusions. And therefore Aristotle says Metaph. v, text 6), that there are some necessary things which have a cause of their necessity. But the reason why an efficient cause is required is not merely because the effect is not necessary, but because the effect might not be if the cause were not. For this conditional proposition is true, whether the antecedent and consequent be possible or impossible.
7 Ad secundum dicendum quod ex hac ratione quidam moti fuerunt ad ponendum quod id quod est necessarium non habeat causam, ut dicitur in VIII Physic. Sed hoc manifeste falsum apparet in scientiis demonstrativis, in quibus principia necessaria sunt causae conclusionum necessariarum. Et ideo dicit Aristoteles, in V Metaphys., quod sunt quaedam necessaria quae habent causam suae necessitatis. Non ergo propter hoc solum requiritur causa agens, quia effectus potest non esse, sed quia effectus non esset, si causa non esset. Haec enim conditionalis est vera, sive antecedens et consequens sint possibilia, sive impossibilia.
8 Reply to Objection 3: The science of mathematics treats its object as though it were something abstracted mentally, whereas it is not abstract in reality. Now, it is becoming that everything should have an efficient cause in proportion to its being. And so, although the object of mathematics has an efficient cause, still, its relation to that cause is not the reason why it is brought under the consideration of the mathematician, who therefore does not demonstrate that object from its efficient cause.
8 Ad tertium dicendum quod mathematica accipiuntur ut abstracta secundum rationem, cum tamen non sint abstracta secundum esse. Unicuique autem competit habere causam agentem, secundum quod habet esse. Licet igitur ea quae sunt mathematica habeant causam agentem, non tamen secundum habitudinem quam habent ad causam agentem, cadunt sub consideratione mathematici. Et ideo in scientiis mathematicis non demonstratur aliquid per causam agentem.
