Take care that thou art not made into a Caesar, that thou art not dyed with this dye; for such things happen. Keep thyself then simple, good, pure, serious, free from affectation, a friend of justice, a worshipper of the gods, kind, affectionate, strenuous in all proper acts. Strive to continue to be such as philosophy wished to make thee. Reverence the gods, and help men. Short is life. There is only one fruit of this terrene life, a pious disposition and social acts. Do everything as a disciple of Antoninus. Remember his constancy in every act which was conformable to reason, and his evenness in all things, and his piety, and the serenity of his countenance, and his sweetness, and his disregard of empty fame, and his efforts to understand things; and how he would never let anything pass without having first most carefully examined it and clearly understood it; and how he bore with those who blamed him unjustly without blaming them in return; how he did nothing in a hurry; and how he listened not to calumnies, and how exact an examiner of manners and actions he was; and not given to reproach people, nor timid, nor suspicious, nor a sophist; and with how little he was satisfied, such as lodging, bed, dress, food, servants; and how laborious and patient; and how he was able on account of his sparing diet to hold out to the evening, not even requiring to relieve himself by any evacuations except at the usual hour; and his firmness and uniformity in his friendships; and how he tolerated freedom of speech in those who opposed his opinions; and the pleasure that he had when any man showed him anything better; and how religious he was without superstition. Imitate all this that thou mayest have as good a conscience, when thy last hour comes, as he had.
When thou hast seen Satyron the Socratic, think of either Eutyches or Hymen, and when thou hast seen Euphrates, think of Eutychion or Silvanus, and when thou hast seen Alciphron think of Tropaeophorus, and when thou hast seen Xenophon think of Crito or Severus, and when thou hast looked on thyself, think of any other Caesar, and in the case of every one do in like manner. Then let this thought be in thy mind, Where then are those men? Nowhere, or nobody knows where. For thus continuously thou wilt look at human things as smoke and nothing at all; especially if thou reflectest at the same time that what has once changed will never exist again in the infinite duration of time. But thou, in what a brief space of time is thy existence? And why art thou not content to pass through this short time in an orderly way?
