Whether strife is a daughter of anger?

Objections

Objection 1 : It would seem that strife is not a daughter of anger. For it is written (James 4:1): "Whence are wars and contentions? Are they not . . . from your concupiscences, which war in your members?" But anger is not in the concupiscible faculty. Therefore strife is a daughter, not of anger, but of concupiscence.
Objection 2 : Further, it is written (Prov. 28:25): "He that boasteth and puffeth up himself, stirreth up quarrels." Now strife is apparently the same as quarrel. Therefore it seems that strife is a daughter of pride or vainglory which makes a man boast and puff himself up.
Objection 3 : Further, it is written (Prov. 18:6): "The lips of a fool intermeddle with strife." Now folly differs from anger, for it is opposed, not to meekness, but to wisdom or prudence. Therefore strife is not a daughter of anger.
Objection 4 : Further, it is written (Prov. 10:12): "Hatred stirreth up strifes." But hatred arises from envy, according to Gregory (Moral. xxxi, 17). Therefore strife is not a daughter of anger, but of envy.
Objection 5 : Further, it is written (Prov. 17:19): "He that studieth discords, soweth [Vulg.: 'loveth'] quarrels." But discord is a daughter of vainglory, as stated above (Question [37], Article [2]). Therefore strife is also.
