SECOND ARTICLE [I, Q. 90, Art. 2]

Whether the Soul Was Produced by Creation?

Objection 1: It would seem that the soul was not produced by

creation. For that which has in itself something material is produced

from matter. But the soul is in part material, since it is not a pure

act. Therefore the soul was made of matter; and hence it was not

created.

Obj. 2: Further, every actuality of matter is educed from the

potentiality of that matter; for since matter is in potentiality to

act, any act pre-exists in matter potentially. But the soul is the

act of corporeal matter, as is clear from its definition. Therefore

the soul is educed from the potentiality of matter.

Obj. 3: Further, the soul is a form. Therefore, if the soul is

created, all other forms also are created. Thus no forms would come

into existence by generation; which is not true.

_On the contrary,_ It is written (Gen. 1:27): "God created man to His

own image." But man is like to God in his soul. Therefore the soul

was created.

_I answer that,_ The rational soul can be made only by creation;

which, however, is not true of other forms. The reason is because,

since to be made is the way to existence, a thing must be made in

such a way as is suitable to its mode of existence. Now that properly

exists which itself has existence; as it were, subsisting in its own

existence. Wherefore only substances are properly and truly called

beings; whereas an accident has not existence, but something is

(modified) by it, and so far is it called a being; for instance,

whiteness is called a being, because by it something is white. Hence

it is said _Metaph._ vii, Did. vi, 1 that an accident should be

described as "of something rather than as something." The same is to

be said of all non-subsistent forms. Therefore, properly speaking,

it does not belong to any non-existing form to be made; but such are

said to be made through the composite substances being made. On the

other hand, the rational soul is a subsistent form, as above

explained (Q. 75, A. 2). Wherefore it is competent to be and to be

made. And since it cannot be made of pre-existing matter--whether

corporeal, which would render it a corporeal being--or spiritual,

which would involve the transmutation of one spiritual substance into

another, we must conclude that it cannot exist except by creation.

Reply Obj. 1: The soul's simple essence is as the material element,

while its participated existence is its formal element; which

participated existence necessarily co-exists with the soul's essence,

because existence naturally follows the form. The same reason holds

if the soul is supposed to be composed of some spiritual matter, as

some maintain; because the said matter is not in potentiality to

another form, as neither is the matter of a celestial body; otherwise

the soul would be corruptible. Wherefore the soul cannot in any way

be made of pre-existent matter.

Reply Obj. 2: The production of act from the potentiality of matter

is nothing else but something becoming actually that previously was

in potentiality. But since the rational soul does not depend in its

existence on corporeal matter, and is subsistent, and exceeds the

capacity of corporeal matter, as we have seen (Q. 75, A. 2), it is

not educed from the potentiality of matter.

Reply Obj. 3: As we have said, there is no comparison between the

rational soul and other forms.
