THIRD ARTICLE [I, Q. 44, Art. 3]

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.

Obj. 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.

Obj. 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.

Obj. 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 Obj. 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 Obj. 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 Obj. 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 Obj. 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.
