Whether the Philosopher suitably assigns the species of anger?

Objections

Objection 1 : It would seem that the species of anger are unsuitably assigned by the Philosopher (Ethic. iv, 5) where he says that some angry persons are "choleric," some "sullen," and some "ill-tempered" or "stern." According to him, a person is said to be "sullen" whose anger "is appeased with difficulty and endures a long time." But this apparently pertains to the circumstance of time. Therefore it seems that anger can be differentiated specifically in respect also of the other circumstances.
Objection 2 : Further, he says (Ethic. iv, 5) that "ill-tempered" or "stern" persons "are those whose anger is not appeased without revenge, or punishment." Now this also pertains to the unquenchableness of anger. Therefore seemingly the ill-tempered is the same as bitterness.
Objection 3 : Further, our Lord mentions three degrees of anger, when He says (Mt. 5:22): "Whosoever is angry with his brother, shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council, and whosoever shall say" to his brother, "Thou fool." But these degrees are not referable to the aforesaid species. Therefore it seems that the above division of anger is not fitting.
