Part I (Prima Pars) Part 178 (2/2)

_On the contrary,_ It is said (De Eccl. Dogmat. xiv, xviii) that ”the soul is created together with the body.”

_I answer that,_ Some have maintained that it is accidental to the intellectual soul to be united to the body, a.s.serting that the soul is of the same nature as those spiritual substances which are not united to a body. These, therefore, stated that the souls of men were created together with the angels at the beginning. But this statement is false. Firstly, in the very principle on which it is based. For if it were accidental to the soul to be united to the body, it would follow that man who results from this union is a being by accident; or that the soul is a man, which is false, as proved above (Q. 75, A.

4). Moreover, that the human soul is not of the same nature as the angels, is proved from the different mode of understanding, as shown above (Q. 55, A. 2; Q. 85, A. 1): for man understands through receiving from the senses, and turning to phantasms, as stated above (Q. 84, AA. 6, 7; Q. 85, A. 1). For this reason the soul needs to be united to the body, which is necessary to it for the operation of the sensitive part: whereas this cannot be said of an angel.

Secondly, this statement can be proved to be false in itself. For if it is natural to the soul to be united to the body, it is unnatural to it to be without a body, and as long as it is without a body it is deprived of its natural perfection. Now it was not fitting that G.o.d should begin His work with things imperfect and unnatural, for He did not make man without a hand or a foot, which are natural parts of a man. Much less, therefore, did He make the soul without a body.

But if someone say that it is not natural to the soul to be united to the body, he must give the reason why it is united to a body. And the reason must be either because the soul so willed, or for some other reason. If because the soul willed it--this seems incongruous. First, because it would be unreasonable of the soul to wish to be united to the body, if it did not need the body: for if it did need it, it would be natural for it to be united to it, since ”nature does not fail in what is necessary.” Secondly, because there would be no reason why, having been created from the beginning of the world, the soul should, after such a long time, come to wish to be united to the body. For a spiritual substance is above time, and superior to the heavenly revolutions. Thirdly, because it would seem that this body was united to this soul by chance: since for this union to take place two wills would have to concur--to wit, that of the incoming soul, and that of the begetter. If, however, this union be neither voluntary nor natural on the part of the soul, then it must be the result of some violent cause, and to the soul would have something of a penal and afflicting nature. This is in keeping with the opinion of Origen, who held that souls were embodied in punishment of sin. Since, therefore, all these opinions are unreasonable, we must simply confess that souls were not created before bodies, but are created at the same time as they are infused into them.

Reply Obj. 1: G.o.d is said to have rested on the seventh day, not from all work, since we read (John 5:17): ”My Father worketh until now”; but from the creation of any new genera and species, which may not have already existed in the first works. For in this sense, the souls which are created now, existed already, as to the likeness of the species, in the first works, which included the creation of Adam's soul.

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 G.o.d should make the soul without the body from the beginning: for as it is written (Wis. 1:13, 16): ”G.o.d 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 s.e.m.e.n, 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.

Obj. 2: Further, the Philosopher (De Gener. i, 5) distinguishes flesh belonging to the species from flesh belonging to ”matter”; and says that the latter ”comes and goes.” Now what is formed from food comes and goes. Therefore what is produced from food is flesh belonging to matter, not to the species. But what belongs to true human nature belongs to the species. Therefore the food is not changed into true human nature.

Obj. 3: Further, the ”radical humor” seems to belong to the reality of human nature; and if it be lost, it cannot be recovered, according to physicians. But it could be recovered if the food were changed into the humor. Therefore food is not changed into true human nature.

Obj. 4: Further, if the food were changed into true human nature, whatever is lost in man could be restored. But man's death is due only to the loss of something. Therefore man would be able by taking food to insure himself against death in perpetuity.

Obj. 5: Further, if the food is changed into true human nature, there is nothing in man which may not recede or be repaired: for what is generated in a man from his food can both recede and be repaired. If therefore a man lived long enough, it would follow that in the end nothing would be left in him of what belonged to him at the beginning. Consequently he would not be numerically the same man throughout his life; since for the thing to be numerically the same, ident.i.ty of matter is necessary. But this is incongruous. Therefore the food is not changed into true human nature.

_On the contrary,_ Augustine says (De Vera Relig. xi): ”The bodily food when corrupted, that is, having lost its form, is changed into the texture of the members.” But the texture of the members belongs to true human nature. Therefore the food is changed into the reality of human nature.

_I answer that,_ According to the Philosopher (Metaph. ii), ”The relation of a thing to truth is the same as its relation to being.”

Therefore that belongs to the true nature of any thing which enters into the const.i.tution of that nature. But nature can be considered in two ways: firstly, in general according to the species; secondly, as in the individual. And whereas the form and the common matter belong to a thing's true nature considered in general; individual signate matter, and the form individualized by that matter belong to the true nature considered in this particular individual. Thus a soul and body belong to the true human nature in general, but to the true human nature of Peter and Martin belong this soul and this body.
