THIRD ARTICLE [I, Q. 90, Art. 3]

Whether the Rational Soul Is Produced by God Immediately?

Objection 1: It would seem that the rational soul is not immediately

made by God, but by the instrumentality of the angels. For spiritual

things have more order than corporeal things. But inferior bodies are

produced by means of the superior, as Dionysius says (Div. Nom. iv).

Therefore also the inferior spirits, who are the rational souls, are

produced by means of the superior spirits, the angels.

Obj. 2: Further, the end corresponds to the beginning of things; for

God is the beginning and end of all. Therefore the issue of things

from their beginning corresponds to the forwarding of them to their

end. But "inferior things are forwarded by the higher," as Dionysius

says (Eccl. Hier. v); therefore also the inferior are produced into

existence by the higher, and souls by angels.

Obj. 3: Further, "perfect is that which can produce its like," as is

stated _Metaph._ v. But spiritual substances are much more perfect

than corporeal. Therefore, since bodies produce their like in their

own species, much more are angels able to produce something

specifically inferior to themselves; and such is the rational soul.

_On the contrary,_ It is written (Gen. 2:7) that God Himself

"breathed into the face of man the breath of life."

_I answer that,_ Some have held that angels, acting by the power of

God, produce rational souls. But this is quite impossible, and is

against faith. For it has been proved that the rational soul cannot

be produced except by creation. Now, God alone can create; for the

first agent alone can act without presupposing the existence of

anything; while the second cause always presupposes something derived

from the first cause, as above explained (Q. 75, A. 3): and every

agent, that presupposes something to its act, acts by making a change

therein. Therefore everything else acts by producing a change,

whereas God alone acts by creation. Since, therefore, the rational

soul cannot be produced by a change in matter, it cannot be produced,

save immediately by God.

Thus the replies to the objections are clear. For that bodies produce

their like or something inferior to themselves, and that the higher

things lead forward the inferior--all these things are effected

through a certain transmutation.
