Reply Obj. 2: Both "sullen" and "ill-tempered" people have a long-lasting anger, but for different reasons. For a "sullen" person has an abiding anger on account of an abiding displeasure, which he holds locked in his breast; and as he does not break forth into the outward signs of anger, others cannot reason him out of it, nor does he of his own accord lay aside his anger, except his displeasure wear away with time and thus his anger cease. On the other hand, the anger of "ill-tempered" persons is long-lasting on account of their intense desire for revenge, so that it does not wear out with time, and can be quelled only by revenge.
Reply Obj. 3: The degrees of anger mentioned by our Lord do not refer to the different species of anger, but correspond to the course of the human act [*Cf. I-II, Q. 46, A. 8, Obj. 3]. For the first degree is an inward conception, and in reference to this He says: "Whosoever is angry with his brother." The second degree is when the anger is manifested by outward signs, even before it breaks out into effect; and in reference to this He says: "Whosoever shall say to his brother, Raca!" which is an angry exclamation. The third degree is when the sin conceived inwardly breaks out into effect. Now the effect of anger is another's hurt under the aspect of revenge; and the least of hurts is that which is done by a mere word; wherefore in reference to this He says: "Whosoever shall say to his brother Thou fool!" Consequently it is clear that the second adds to the first, and the third to both the others; so that, if the first is a mortal sin, in the case referred to by our Lord, as stated above (A. 3, ad 2), much more so are the others. Wherefore some kind of condemnation is assigned as corresponding to each one of them. In the first case "judgment" is assigned, and this is the least severe, for as Augustine says [*Serm. Dom. in Monte i, 9], "where judgment is to be delivered, there is an opportunity for defense": in the second case "council" is assigned, "whereby the judges deliberate together on the punishment to be inflicted": to the third case is assigned "hell-fire," i.e. "decisive condemnation." _______________________
SIXTH ARTICLE [II-II, Q. 158, Art. 6]
Whether Anger Should Be Reckoned Among the Capital Vices?
Objection 1: It would seem that anger should not be reckoned among the capital sins. For anger is born of sorrow which is a capital vice known by the name of sloth. Therefore anger should not be reckoned a capital vice.
Obj. 2: Further, hatred is a graver sin than anger. Therefore it should be reckoned a capital vice rather than anger.
Obj. 3: Further, a gloss on Prov. 29:22, "An angry [Douay: 'passionate'] man provoketh quarrels," says: "Anger is the door to all vices: if it be closed, peace is ensured within to all the virtues; if it be opened, the soul is armed for every crime." Now no capital vice is the origin of all sins, but only of certain definite ones. Therefore anger should not be reckoned among the capital vices.
On the contrary, Gregory (Moral. xxxi, 45) places anger among the capital vices.
I answer that, As stated above (I-II, Q. 84, A. 3, 4), a capital vice is defined as one from which many vices arise. Now there are two reasons for which many vices can arise from anger. The first is on the part of its object which has much of the aspect of desirability, in so far as revenge is desired under the aspect of just or honest*, which is attractive by its excellence, as stated above (A. 4). [*Honesty must be taken here in its broad sense as synonymous with moral goodness, from the point of view of decorum; Cf. Q. 145, A. 1.] The second is on the part of its impetuosity, whereby it precipitates the mind into all kinds of inordinate action. Therefore it is evident that anger is a capital vice.
Reply Obj. 1: The sorrow whence anger arises is not, for the most part, the vice of sloth, but the passion of sorrow, which results from an injury inflicted.
