Thomas Aquinas, Summa Theologiae

Objection 1: It would seem that primary matter is not created by God. For whatever is made is composed of a subject and of something else (Phys. i, text 62). But primary matter has no subject. Therefore primary matter cannot have been made by God.

Objection 2: Further, action and passion are opposite members of a division. But as the first active principle is God, so the first passive principle is matter. Therefore God and primary matter are two principles divided against each other, neither of which is from the other.

Objection 3: Further, every agent produces its like, and thus, since every agent acts in proportion to its actuality, it follows that everything made is in some degree actual. But primary matter is only in potentiality, formally considered in itself. Therefore it is against the nature of primary matter to be a thing made.

On the contrary, Augustine says (Confess. xii, 7), Two "things hast Thou made, O Lord; one nigh unto Thyself"---viz. angels---"the other nigh unto nothing"---viz. primary matter.

I answer that, The ancient philosophers gradually, and as it were step by step, advanced to the knowledge of truth. At first being of grosser mind, they failed to realize that any beings existed except sensible bodies. And those among them who admitted movement, did not consider it except as regards certain accidents, for instance, in relation to rarefaction and condensation, by union and separation. And supposing as they did that corporeal substance itself was uncreated, they assigned certain causes for these accidental changes, as for instance, affinity, discord, intellect, or something of that kind. An advance was made when they understood that there was a distinction between the substantial form and matter, which latter they imagined to be uncreated, and when they perceived transmutation to take place in bodies in regard to essential forms. Such transmutations they attributed to certain universal causes, such as the oblique circle , according to Aristotle (De Gener. ii), or ideas, according to Plato. But we must take into consideration that matter is contracted by its form to a determinate species, as a substance, belonging to a certain species, is contracted by a supervening accident to a determinate mode of being; for instance, man by whiteness. Each of these opinions, therefore, considered "being" under some particular aspect, either as "this" or as "such"; and so they assigned particular efficient causes to things. Then others there were who arose to the consideration of "being," as being, and who assigned a cause to things, not as "these," or as "such," but as "beings."

Therefore whatever is the cause of things considered as beings, must be the cause of things, not only according as they are "such" by accidental forms, nor according as they are "these" by substantial forms, but also according to all that belongs to their being at all in any way. And thus it is necessary to say that also primary matter is created by the universal cause of things.

Reply to Objection 1: The Philosopher (Phys. i, text 62), is speaking of "becoming" in particular---that is, from form to form, either accidental or substantial. But here we are speaking of things according to their emanation from the universal principle of being; from which emanation matter itself is not excluded, although it is excluded from the former mode of being made.

Reply to Objection 2: Passion is an effect of action. Hence it is reasonable that the first passive principle should be the effect of the first active principle, since every imperfect thing is caused by one perfect. For the first principle must be most perfect, as Aristotle says (Metaph. xii, text 40).

Reply to Objection 3: The reason adduced does not show that matter is not created, but that it is not created without form; for though everything created is actual, still it is not pure act. Hence it is necessary that even what is potential in it should be created, if all that belongs to its being is created.

Argumentum 1

Ad secundum sic proceditur. Videtur quod materia prima non sit creata a deo.

Omne enim quod fit, componitur ex subiecto et ex aliquo alio, ut dicitur in I physic..

Sed materiae primae non est aliquod subiectum.

Ergo materia prima non potest esse facta a deo.

Argumentum 2

Praeterea, actio et passio dividuntur contra se invicem. Sed sicut primum principium activum est deus, ita primum principium passivum est materia. Ergo deus et materia prima sunt duo principia contra se invicem divisa, quorum neutrum est ab alio.

Argumentum 3

Praeterea, omne agens agit sibi simile, et sic, cum omne agens agat inquantum est actu, sequitur quod omne factum aliquo modo sit in actu. Sed materia prima est tantum in potentia, inquantum huiusmodi. Ergo contra rationem materiae primae est, quod sit facta.

Sed Contra

Sed contra est quod dicit Augustinus, XII confess., duo fecisti, domine, unum prope te, scilicet Angelum, aliud prope nihil, scilicet materiam primam.

Corpus

Respondeo dicendum quod antiqui philosophi paulatim, et quasi pedetentim, intraverunt in cognitionem veritatis. A principio enim, quasi grossiores existentes, non existimabant esse entia nisi corpora sensibilia. Quorum qui ponebant in eis motum, non considerabant motum nisi secundum aliqua accidentia, ut puta secundum raritatem et densitatem, congregationem et segregationem. Et supponentes ipsam substantiam corporum increatam, assignabant aliquas causas huiusmodi accidentalium transmutationum, ut puta amicitiam, litem, intellectum, aut aliquid huiusmodi.

Ulterius vero procedentes, distinxerunt per intellectum inter formam substantialem et materiam, quam ponebant increatam; et perceperunt transmutationem fieri in corporibus secundum formas essentiales. Quarum transmutationum quasdam causas universaliores ponebant, ut obliquum circulum, secundum Aristotelem, vel ideas, secundum Platonem. Sed considerandum est quod materia per formam contrahitur ad determinatam speciem; sicut substantia alicuius speciei per accidens ei adveniens contrahitur ad determinatum modum essendi, ut homo contrahitur per album.

Utrique igitur consideraverunt ens particulari quadam consideratione, vel inquantum est hoc ens, vel inquantum est tale ens. Et sic rebus causas agentes particulares assignaverunt.

Et ulterius aliqui erexerunt se ad considerandum ens inquantum est ens, et consideraverunt causam rerum, non solum secundum quod sunt haec vel talia, sed secundum quod sunt entia. Hoc igitur quod est causa rerum inquantum sunt entia, oportet esse causam rerum, non solum secundum quod sunt talia per formas accidentales, nec secundum quod sunt haec per formas substantiales, sed etiam secundum omne illud quod pertinet ad esse illorum quocumque modo. Et sic oportet ponere etiam materiam primam creatam ab universali causa entium.

Ad 1

Ad primum ergo dicendum quod philosophus in I physic. Loquitur de fieri particulari, quod est de forma in formam, sive accidentalem sive substantialem nunc autem loquimur de rebus secundum emanationem earum ab universali principio essendi. A qua quidem emanatione nec materia excluditur, licet a primo modo factionis excludatur.

Ad 2

Ad secundum dicendum quod passio est effectus actionis. Unde et rationabile est quod primum principium passivum sit effectus primi principii activi, nam omne imperfectum causatur a perfecto.

Oportet enim primum principium esse perfectissimum, ut dicit Aristoteles, in XII metaphys..

Ad 3

Ad tertium dicendum quod ratio illa non ostendit quod materia non sit creata, sed quod non sit creata sine forma. Licet enim omne creatum sit in actu, non tamen est actus purus. Unde oportet quod etiam illud quod se habet ex parte potentiae, sit creatum, si totum quod ad esse ipsius pertinet, creatum est.
