Reply Obj. 2: Something can be added every day to the perfection of the universe, as to the number of individuals, but not as to the number of species.
Reply Obj. 3: That the soul remains without the body is due to the corruption of the body, which was a result of sin. Consequently it was not fitting that God should make the soul without the body from the beginning: for as it is written (Wis. 1:13, 16): "God made not death . . . but the wicked with works and words have called it to them." _______________________
QUESTION 119
OF THE PROPAGATION OF MAN AS TO THE BODY
(In Two Articles)
We now consider the propagation of man, as to the body. Concerning this there are two points of inquiry:
(1) Whether any part of the food is changed into true human nature?
(2) Whether the semen, which is the principle of human generation, is produced from the surplus food? _______________________
FIRST ARTICLE [I, Q. 119, Art. 1]
Whether Some Part of the Food Is Changed into True Human Nature?
Objection 1: It would seem that none of the food is changed into true human nature. For it is written (Matt. 15:17): "Whatsoever entereth into the mouth, goeth into the belly, and is cast out into the privy." But what is cast out is not changed into the reality of human nature. Therefore none of the food is changed into true human nature.
