Epictetus 3.22.1-4
When one of his acquaintances, who seemed to have an inclination to take up the calling of a Cynic, asked him what sort of a man the Cynic ought to be, and what was the fundamental conception of his calling, Epictetus said: We will consider it at leisure; but I can tell you this much, that the man who lays his hand to so great a matter as this without God, is hateful to Him, and his wish means nothing else than disgracing himself in public. For in a well-ordered house no one comes along and says to himself, "I ought to be manager of this house"; or if he does, the lord of the mansion, when he turns around and sees the fellow giving orders in a high and mighty fashion, drags him out and gives him a dressing down. So it goes also in this great city, the world; for here also there is a Lord of the Mansion who assigns each and every thing its place.
