Thus a man of knowledge endeavors, and sweats, and puffs, and if one looks at him he is just like any ordinary man, except that the folly of his life is under control. Nothing being more important than anything else, a man of knowledge chooses any act, and acts it out as if it matters to him. His controlled folly makes him say that what he does matters and makes him act as if it did, and yet he knows that it doesn't; so when he fulfills his acts he retreats in peace, and whether his acts were good or bad, or worked or didn't, is in no way part of his concern.
