Marcus Aurelius
Meditations 12.16
When a man has presented the appearance of having done wrong [say], How then do I know if this is a wrongful act? And even if he has done wrong, how do I know that he has not condemned himself? And so this is like tearing his own face. Consider that he who would not have the bad man do wrong, is like the man who would not have the fig-tree to bear juice in the figs, and infants to cry, and the horse to neigh, and whatever else must of necessity be. For what must a man do who has such a character? If then thou art irritable, cure this man's disposition.
Marcus Aurelius, Meditations 12.16, translated by George Long
Another has given thee cause to think that he has done wrong: But how do I know that it is a wrong? And even if he be guilty, suppose that his own heart has condemned him, and so he is as one who wounds his own face?
Note that he who would not have the wicked do wrong is as one who would not have the fig-tree secrete acrid juice in its fruit, would not have babies cry, or the horse neigh, or have any other things be that must be. Why, what else can be expected from such a disposition? If then it chafes thee, cure the disposition.
Marcus Aurelius, Meditations 12.16, translated by C. R. Haines
