Epictetus. (c.A.D. 50c.A.D. 138). The Golden Sayings of Epictetus.
The Harvard Classics. 190914.
Thou wouldst do good unto men? then show them by thine own example what kind of men philosophy can make, and cease from foolish trifling. Eating, do good to them that eat with thee; drinking, to them that drink with thee; yield unto all, give way, and bear with them. Thus shalt thou do them good: but vent not upon them thine own evil humour!
