Now it is evident that the more excellent a man is, the more unjust is a slight offered him in the matter in which he excels.

“I answer that, The cause of anger, in the man who is angry, may be taken in two ways. First in respect of the motive of anger: and thus excellence is the cause of a man being easily angered. Because the motive of anger is an unjust slight, as stated above (A. 2) . Now it is evident that the more excellent a man is, the more unjust is a slight offered him in the matter in which he excels. Consequently those who excel in any matter, are most of all angry, if they be slighted in that matter; for instance, a wealthy man in his riches, or an orator in his eloquence, and so forth. Secondly, the cause of anger, in the man who is angry, may be considered on the part of the disposition produced in him by the motive aforesaid.” source
