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.
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.
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.
On the contrary, It is said (Romans 11:36): "Of Him, and by Him, and in Him are all things."
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 (I:3:4) when treating of the divine simplicity that God is the essentially self-subsisting Being; and also it was shown (I:11:4) 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.
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.
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.
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.
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.
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 [The zodiac], 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.
Objection 1. It would seem that the exemplar cause is something besides God. For the effect is like its exemplar cause. But creatures are far from being like God. Therefore God is not their exemplar cause.
Objection 2. Further, whatever is by participation is reduced to something self-existing, as a thing ignited is reduced to fire, as stated above (Article 1). But whatever exists in sensible things exists only by participation of some species. This appears from the fact that in all sensible species is found not only what belongs to the species, but also individuating principles added to the principles of the species. Therefore it is necessary to admit self-existing species, as for instance, a per se man, and a per se horse, and the like, which are called the exemplars. Therefore exemplar causes exist besides God.
Objection 3. Further, sciences and definitions are concerned with species themselves, but not as these are in particular things, because there is no science or definition of particular things. Therefore there are some beings, which are beings or species not existing in singular things, and these are called exemplars. Therefore the same conclusion follows as above.
Objection 4. Further, this likewise appears from Dionysius, who says (Div. Nom. v) that self-subsisting being is before self-subsisting life, and before self-subsisting wisdom.
On the contrary, The exemplar is the same as the idea. But ideas, according to Augustine (QQ. 83, qu. 46), are "the master forms, which are contained in the divine intelligence." Therefore the exemplars of things are not outside God.
I answer that, God is the first exemplar cause of all things. In proof whereof we must consider that if for the production of anything an exemplar is necessary, it is in order that the effect may receive a determinate form. For an artificer produces a determinate form in matter by reason of the exemplar before him, whether it is the exemplar beheld externally, or the exemplar interiorily conceived in the mind. Now it is manifest that things made by nature receive determinate forms. This determination of forms must be reduced to the divine wisdom as its first principle, for divine wisdom devised the order of the universe, which order consists in the variety of things. And therefore we must say that in the divine wisdom are the types of all things, which types we have called ideas--i.e. exemplar forms existing in the divine mind (I:15:1. And these ideas, though multiplied by their relations to things, in reality are not apart from the divine essence, according as the likeness to that essence can be shared diversely by different things. In this manner therefore God Himself is the first exemplar of all things. Moreover, in things created one may be called the exemplar of another by the reason of its likeness thereto, either in species, or by the analogy of some kind of imitation.
Reply to Objection 1. Although creatures do not attain to a natural likeness to God according to similitude of species, as a man begotten is like to the man begetting, still they do attain to likeness to Him, forasmuch as they represent the divine idea, as a material house is like to the house in the architect's mind.
Reply to Objection 2. It is of a man's nature to be in matter, and so a man without matter is impossible. Therefore although this particular man is a man by participation of the species, he cannot be reduced to anything self-existing in the same species, but to a superior species, such as separate substances. The same applies to other sensible things.
Reply to Objection 3. Although every science and definition is concerned only with beings, still it is not necessary that a thing should have the same mode in reality as the thought of it has in our understanding. For we abstract universal ideas by force of the active intellect from the particular conditions; but it is not necessary that the universals should exist outside the particulars in order to be their exemplars.
Reply to Objection 4. As Dionysius says (Div. Nom. iv), by "self-existing life and self-existing wisdom" he sometimes denotes God Himself, sometimes the powers given to things themselves; but not any self-subsisting things, as the ancients asserted.
Objection 1. It would seem that God is not the final cause of all things. For to act for an end seems to imply need of the end. But God needs nothing. Therefore it does not become Him to act for an end.
Objection 2. Further, the end of generation, and the form of the thing generated, and the agent cannot be identical (Phys. ii, text 70), because the end of generation is the form of the thing generated. But God is the first agent producing all things. Therefore He is not the final cause of all things.
On the contrary, It is said (Proverbs 16:4): "The Lord has made all things for Himself."
I answer that, Every agent acts for an end: otherwise one thing would not follow more than another from the action of the agent, unless it were by chance. Now the end of the agent and of the patient considered as such is the same, but in a different way respectively. For the impression which the agent intends to produce, and which the patient intends to receive, are one and the same. Some things, however, are both agent and patient at the same time: these are imperfect agents, and to these it belongs to intend, even while acting, the acquisition of something. But it does not belong to the First Agent, Who is agent only, to act for the acquisition of some end; He intends only to communicate His perfection, which is His goodness; while every creature intends to acquire its own perfection, which is the likeness of the divine perfection and goodness. Therefore the divine goodness is the end of all things.
Reply to Objection 1. To act from need belongs only to an imperfect agent, which by its nature is both agent and patient. But this does not belong to God, and therefore He alone is the most perfectly liberal giver, because He does not act for His own profit, but only for His own goodness.
Reply to Objection 2. The form of the thing generated is not the end of generation, except inasmuch as it is the likeness of the form of the generator, which intends to communicate its own likeness; otherwise the form of the thing generated would be more noble than the generator, since the end is more noble than the means to the end.
Reply to Objection 3. All things desire God as their end, when they desire some good thing, whether this desire be intellectual or sensible, or natural, i.e. without knowledge; because nothing is good and desirable except forasmuch as it participates in the likeness to God.
Reply to Objection 4. Since God is the efficient, the exemplar and the final cause of all things, and since primary matter is from Him, it follows that the first principle of all things is one in reality. But this does not prevent us from mentally considering many things in Him, some of which come into our mind before others.
