That which is past is gone, and irrevocable; and wise men have enough to do with things present and to come: therefore they do but trifle with themselves, that labour in past matters.
There is no man doth a wrong for the wrong's sake; but thereby to purchase himself profit, or pleasure, or honour, or the like. There why should I be angry with a man for loving himself better than me? And if any man should do wrong merely out of ill nature, why, yet it is but like the thorn or briar, which prick and scratch, because they can do no other.
The most tolerable sort of revenge is for those wrongs which there is no law or remedy; but then let a man take heed the revenge be such as there is no law to punish; else a man's enemy is still beforehand, and it is two for one.
Some, when they take revenge, are desirous the party should know whence it cometh: this is the more generous. For the delight seemeth to be not so much in doing the hurt as in making the party repent: but base and crafty cowards are like the arrow that flieth in the dark.
Cosmus, Duke of Florence, had a desperate saying against perfidious or neglecting friends, as if those wrongs were unpardonable: You shall read (saith he) that we are commanded to forgive our friends. But yet the spirit of Job was in a better tune: Shall we (saith he) take good at God's hands, and not be content to take evil also? And so of friends in a proportion.
This is certain, that a man that studieth revenge keeps his own wounds green, which otherwise would heal and do well.
Public revenges are for the most part fortunate; as that for the death of Caesar; for the death of Pertinax; for the death of Henry the Third of France; and many more. But in private revenges it is not so. Nay rather, vindictive persons live the life of witches; who as they are mischievous, so end they unfortunate.
