Whether contention is a daughter of vainglory?

Objections

Objection 1 : It would seem that contention is not a daughter of vainglory. For contention is akin to zeal, wherefore it is written (1 Cor. 3:3): "Whereas there is among you zeal [Douay: 'envying'] and contention, are you not carnal, and walk according to men?" Now zeal pertains to envy. Therefore contention arises rather from envy.
Objection 2 : Further, contention is accompanied by raising of the voice. But the voice is raised on account of anger, as Gregory declares (Moral. xxxi, 14). Therefore contention too arises from anger.
Objection 3 : Further, among other things knowledge seems to be the matter of pride and vainglory, according to 1 Cor. 8:1: "Knowledge puffeth up." Now contention is often due to lack of knowledge, and by knowledge we do not impugn the truth, we know it. Therefore contention is not a daughter of vainglory.
