Always remember the saying of Heraclitus, that the death of earth is to become water, and the death of water is to become air, and the death of air is to become fire, and reversely. And think too of him who forgets whither the way leads, and that men quarrel with that with which they are most constantly in communion, the reason which governs the universe; and the things which daily meet with seem to them strange: and consider that we ought not to act and speak as if we were asleep, for even in sleep we seem to act and speak; and that we ought not, like children who learn from their parents, simply to act and speak as we have been taught.
How hast thou behaved hitherto to the gods, thy parents, brethren, children, teachers, to those who looked after thy infancy, to thy friends, kinsfolk, to thy slaves? Consider if thou hast hitherto behaved to all in such a way that this may be said of thee: Never has wronged a man in deed or word. And call to recollection both how many things thou hast passed through, and how many things thou hast been able to endure: and that the history of thy life is now complete and thy service is ended: and how many beautiful things thou hast seen: and how many pleasures and pains thou hast despised; and how many things called honourable thou hast spurned; and to how many ill-minded folks thou hast shown a kind disposition.
