CEASE to make yourselves slaves, first of things, and then upon their account, of the men who have the power either to bestow or take them away. Is there any advantage then to be gained from these men? From all, even from a reviler. What advantage doth a wrestler gain from him with whom he exercises himself, before the combat? The greatest. Why, just in the same manner I exercise myself with this man. He exercises me in patience, in gentleness, in meekness. Is my neighbour a bad one? He is so to himself; but a good one to me. He exercises my good temper, my moderation. Is my father bad? To himself, but not to me. "This is the rod of Hermes. Touch with it whatever you please, and it will become gold." No; but bring whatever you please, and I will turn it into good. Bring sickness, death, want, reproach, capital trial. All these, by the rod of Hermes, shall turn to advantage.
