46. Remember always the sayings of Heraclitus: that the death of earth is to become water, the death of water to become air, and the death of air to become fire; and so conversely. Remember in what a case he is who forgets whither the way leads: that men are frequently at variance with their close and constant companion, the reason which rules all: that men count strange that which they meet every day: that we should neither act nor speak as though in slumber, although even in slumber we seem to act and speak; nor yet like children learning from their parents, with a mere acceptance of everything just as we are told it. 47. If some God were to inform you that you must die tomorrow, or the next day at farthest, you would take little concern whether it was to be tomorrow or the next day; that is if you were not the most miserable of cowards. For how small is the difference? Wherefore, account it of no great moment whether you die after many years or tomorrow. 48. Constantly consider how many physicians are dead and gone, who frequently knitted their brows over their patients; how many astrologers, who foretold the deaths of others with great ostentation of their art; how many philosophers, who wrote endlessly on death and immortality; how many warriors, who slew their thousands; and how many tyrants, who used their power of life and death with cruel wantonness, as though they had been immortal. How many whole cities, if I may so speak, are dead: Helice and Pompeii and Herculaneum, and others past counting. Tell over next all those you have known, one after the other: think how one buried his fellow, then lay dead himself, to be buried by a third. And all this within a little time. In sum, look upon human things, and behold how short-lived and how vile they are; mucus yesterday, tomorrow ashes or pickled carrion. Spend, then, the fleeting remnant of your time in a spirit that accords with Nature, and depart contentedly. So the olive falls when it is grown ripe, blessing the ground from whence it sprung, and thankful to the tree that bore it.
