Think continually how many physicians are dead after often contracting their eyebrows over the sick; and how many astrologers after predicting with great pretensions the deaths of others; and how many philosophers after endless discourses on death or immortality; how many heroes after killing thousands; and how many tyrants who have used their power over men's lives with terrible insolence as if they were immortal; and how many cities are entirely dead, so to speak, Helice and Pompeii and Herculaneum, and others innumerable. Add to the reckoning all whom thou hast known, one after another. One man after burying another has been laid out dead, and another buries him: and all this in a short time. To conclude, always observe how ephemeral and worthless human things are, and what was yesterday a little mucus to-morrow will be a mummy or ashes. Pass then through this little space of time conformably to nature, and end thy journey in content, just as an olive falls off when it is ripe, blessing nature who produced it, and thanking the tree on which it grew.
Think continually that all kinds of men and of all kinds of pursuits and of all nations are dead, so that thy thoughts come down even to Philistion and Phoebus and Origanion. Now turn thy thoughts to the other kinds of men. To that place then we must remove, where there are so many great orators, and so many noble philosophers, Heraclitus, Pythagoras, Socrates; so many heroes of former days, and so many generals after them, and tyrants; besides these, Eudoxus, Hipparchus, Archimedes, and other men of acute natural talents, great minds, lovers of labour, versatile, confident, mockers even of the perishable and ephemeral life of man, as Menippus and such as are like him. As to all these consider that they have long been in the dust. What harm then is this to them; and what to those whose names are altogether unknown? One thing here is worth a great deal, to pass thy life in truth and justice, with a benevolent disposition even to liars and unjust men.
