Think continually how many physicians have died, after often knitting their foreheads over their patients; how many astrologers after prophesying other men's deaths, as though to die were a great matter; how many philosophers after endless debate on death or survival after death; how many paladins after slaying their thousands; how many tyrants after using their power over men's lives with monstrous arrogance, as if themselves immortal; how many entire cities have, if I may use the term, died, Helice, Pompeii, Herculaneum, and others innumerable. Run over, too, the many also you know of, one after another. One followed this man's funeral and then was himself laid on the bier; another followed him, and all in a little while. This is the whole matter: see always how ephemeral and cheap are the things of man—yesterday, a spot of albumen, to-morrow, ashes or a mummy. Therefore make your passage through this span of time in obedience to Nature and gladly lay down your life, as an olive, when ripe, might fall, blessing her who bare it and grateful to the tree which gave it life.
