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.
Whether the exemplar cause is anything besides God?
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 (A[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 (Q[15], A[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.
Whether God is the final cause of all things?
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.
Objection 3: Further, all things desire their end. But all things do not desire God, for all do not even know Him. Therefore God is not the end of all things.
Objection 4: Further, the final cause is the first of causes. If, therefore, God is the efficient cause and the final cause, it follows that before and after exist in Him; which is impossible.
On the contrary, It is said ( Prov. 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.
