Nevertheless pride disposes a man to revile, in so far as those who think themselves to excel, are more prone to despise others and inflict injuries on them, because they are more easily angered, through deeming it an affront to themselves whenever anything is done against their will.

Context

“since the easiest way for the angry man to take revenge on another is to revile him. Therefore reviling arises chiefly from anger. Reply Obj. 1: Reviling is not directed to the end of pride which is excellency. Hence reviling does not arise directly from pride. Nevertheless pride disposes a man to revile, in so far as those who think themselves to excel, are more prone to despise others and inflict injuries on them, because they are more easily angered, through deeming it an affront to themselves whenever anything is done against their will. Reply Obj. 2: According to the Philosopher (Ethic. vii, 6) "anger listens imperfectly to reason": wherefore an angry man suffers a defect of reason, and in this he is like the foolish man. Hence reviling arises from folly on account of the latter's kinship with anger.” source
