Reply Obj. 2: As stated above (Q. 118, A. 7; Q. 148, A. 5; Q. 153, A. 4; I-II, Q. 84, A. 4), it belongs to the notion of a capital vice to have a most desirable end, so that many sins are committed through the desire thereof. Now anger, which desires evil under the aspect of good, has a more desirable end than hatred has, since the latter desires evil under the aspect of evil: wherefore anger is more a capital vice than hatred is.
Reply Obj. 3: Anger is stated to be the door to the vices accidentally, that is by removing obstacles, to wit by hindering the judgment of reason, whereby man is withdrawn from evil. It is, however, directly the cause of certain special sins, which are called its daughters. _______________________
SEVENTH ARTICLE [II-II, Q. 158, Art. 7]
Whether Six Daughters Are Fittingly Assigned to Anger?
Objection 1: It would seem that six daughters are unfittingly assigned to anger, namely "quarreling, swelling of the mind, contumely, clamor, indignation and blasphemy." For blasphemy is reckoned by Isidore [*QQ. in Deut., qu. xvi] to be a daughter of pride. Therefore it should not be accounted a daughter of anger.
Obj. 2: Further, hatred is born of anger, as Augustine says in his rule (Ep. ccxi). Therefore it should be placed among the daughters of anger.
Obj. 3: Further, "a swollen mind" would seem to be the same as pride. Now pride is not the daughter of a vice, but "the mother of all vices," as Gregory states (Moral. xxxi, 45). Therefore swelling of the mind should not be reckoned among the daughters of anger.
On the contrary, Gregory (Moral. xxxi, 45) assigns these daughters to anger.
I answer that, Anger may be considered in three ways. First, as consisting in thought, and thus two vices arise from anger. One is on the part of the person with whom a man is angry, and whom he deems unworthy (indignum) of acting thus towards him, and this is called "indignation." The other vice is on the part of the man himself, in so far as he devises various means of vengeance, and with such like thoughts fills his mind, according to Job 15:2, "Will a wise man . . . fill his stomach with burning heat?" And thus we have "swelling of the mind."
Secondly, anger may be considered, as expressed in words: and thus a twofold disorder arises from anger. One is when a man manifests his anger in his manner of speech, as stated above (A. 5, ad 3) of the man who says to his brother, "Raca": and this refers to "clamor," which denotes disorderly and confused speech. The other disorder is when a man breaks out into injurious words, and if these be against God, it is "blasphemy," if against one's neighbor, it is "contumely."
