This suffices for the Reply to the First Objection.
Reply Obj. 2: Apostasy from God is stated to be the beginning of pride, in so far as it denotes a turning away from God, because from the fact that man wishes not to be subject to God, it follows that he desires inordinately his own excellence in temporal things. Wherefore, in the passage quoted, apostasy from God does not denote the special sin, but rather that general condition of every sin, consisting in its turning away from God. It may also be said that apostasy from God is said to be the beginning of pride, because it is the first species of pride. For it is characteristic of pride to be unwilling to be subject to any superior, and especially to God; the result being that a man is unduly lifted up, in respect of the other species of pride.
Reply Obj. 3: In desiring to excel, man loves himself, for to love oneself is the same as to desire some good for oneself. Consequently it amounts to the same whether we reckon pride or self-love as the beginning of every evil. ________________________
THIRD ARTICLE [I-II, Q. 84, Art. 3]
Whether Any Other Special Sins, Besides Pride and Avarice, Should Be
Called Capital?
Objection 1: It would seem that no other special sins, besides pride and avarice, should be called capital. Because "the head seems to be to an animal, what the root is to a plant," as stated in De Anima ii, text. 38: for the roots are like a mouth. If therefore covetousness is called the "root of all evils," it seems that it alone, and no other sin, should be called a capital vice.
Obj. 2: Further, the head bears a certain relation of order to the other members, in so far as sensation and movement follow from the head. But sin implies privation of order. Therefore sin has not the character of head: so that no sins should be called capital.
Obj. 3: Further, capital crimes are those which receive capital punishment. But every kind of sin comprises some that are punished thus. Therefore the capital sins are not certain specific sins.
On the contrary, Gregory (Moral. xxxi, 17) enumerates certain special vices under the name of capital.
I answer that, The word capital is derived from caput (a head). Now the head, properly speaking, is that part of an animal's body, which is the principle and director of the whole animal. Hence, metaphorically speaking, every principle is called a head, and even men who direct and govern others are called heads. Accordingly a capital vice is so called, in the first place, from "head" taken in the proper sense, and thus the name "capital" is given to a sin for which capital punishment is inflicted. It is not in this sense that we are now speaking of capital sins, but in another sense, in which the term "capital" is derived from head, taken metaphorically for a principle or director of others. In this way a capital vice is one from which other vices arise, chiefly by being their final cause, which origin is formal, as stated above (Q. 72, A. 6). Wherefore a capital vice is not only the principle of others, but is also their director and, in a way, their leader: because the art or habit, to which the end belongs, is always the principle and the commander in matters concerning the means. Hence Gregory (Moral. xxxi, 17) compares these capital vices to the "leaders of an army."
