 Greek thinkers after Plato had similarly negative comments about laughter and humor. Though Aristotle considered wit a valuable part of conversation (Nicomachean Ethics 4, 8), he agreed with Plato that laughter expresses scorn. Wit, he says in the Rhetoric (2, 12), is educated insolence. In the Nicomachean Ethics (4, 8) he warns that “Most people enjoy amusement and jesting more than they should … a jest is a kind of mockery, and lawgivers forbid some kinds of mockery—perhaps they ought to have forbidden some kinds of jesting.” The Stoics, with their emphasis on self-control, agreed with Plato that laughter diminishes self-control. Epictetus’s Enchiridion (33) advises “Let not your laughter be loud, frequent, or unrestrained.” His followers said that he never laughed at all.
