History records surprisingly few cheerful people. Philosophers, in particular, have the reputation for being about as miserable as comedians, but Epicurus (341-270BC) isn’t one of them. His poor reputation is of a very different kind: as the high priest of high living and sensual pleasure, the philosopher of the debauchee and the gourmand.
Except that he wasn’t. Far from indulging in orgies and banquets, Epicurus lived on barley bread and fruit, with cheese as a special treat on only feast days. Celibate himself, he discouraged sexual relations among his followers, and his students were allowed no more than a pint of wine a day.
