Book 2.32

"But anger possesses a certain pleasure of its own, and it is sweet to pay back the pain you have suffered." Not at all; it is not honourable to requite injuries by injuries, in the same way as it is to repay benefits by benefits. In the latter case it is a shame to be conquered; in the former it is a shame to conquer. Revenge and retaliation are words which men use and even think to be righteous, yet they do not greatly differ from wrong-doing, except in the order in which they are done: he who renders pain for pain has more excuse for his sin; that is all. Someone who did not know Marcus Cato struck him in the public bath in his ignorance, for who would knowingly have done him an injury? Afterwards when he was apologizing, Cato replied, "I do not remember being struck." He thought it better to ignore the insult than to revenge it. You ask, "Did no harm befall that man for his insolence?" No, but rather much good; he made the acquaintance of Cato. It is the part of a great mind to despise wrongs done to it; the most contemptuous form of revenge is not to deem one's adversary worth taking vengeance upon. Many have taken small injuries much more seriously to heart than they need, by revenging them: that man is great and noble who like a large wild animal hears unmoved the tiny curs that bark at him.
