Plato once wanted to punish one of his slaves and asked his nephew to do the actual whipping for he himself did not own his anger.
Seneca the YoungerVirtue depends partly upon training and partly upon practice; you must learn first, and then strengthen your learning by action. If this be true, not only do the doctrines of wisdom help us but the precepts also, which check and banish our emotions by a sort of official decree.
Seneca the YoungerIt passes in the world for greatness of mind, to be perpetually giving and loading people with bounties; but it is one thing to know how to give and another thing not to know how to keep. Give me a heart that is easy and open, but I will have no holes in it; let it be bountiful with judgment, but I will have nothing run out of it I know not how.
Seneca the Younger
