Being asked by a friend who happened to come in, what he was doing, he answered: “I am making an angry man expiate his crime.” He retained the posture of one about to give way to passion, as if struck with astonishment at its being so degrading to a philosopher, forgetting the slave, because he had found another still more deserving of punishment. He therefore denied himself the exercise of authority over his own household, and once, being rather angry at some fault, said, “Speusippus, will you please to correct that slave with stripes; for I am in a rage.” He would not strike him, for the very reason for which another man would have struck him. “I am in a rage,” said he; “I should beat him more than I ought: I should take more pleasure than I ought in doing so: let not that slave fall into the power of one who is not in his own power.” Can anyone wish to grant the power of revenge to an angry man, when Plato himself gave up his own right to exercise it? While you are angry, you ought not to be allowed to do anything. “Why?” do you ask? Because when you are angry there is nothing that you do not wish to be allowed to do.
