31. When thou hast seen Satyron[A] 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[B] 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? What matter and opportunity [for thy activity] art thou avoiding? For what else are all these things, except exercises for the reason, when it has viewed carefully and by examination into their nature the things which happen in life? Persevere then until thou shalt have made these things thy own, as the stomach which is strengthened makes all things its own, as the blazing fire makes flame and brightness out of everything that is thrown into it. 32. Let it not be in any man's power to say truly of thee that thou are not simple or that thou art not good; but let him be a liar whoever shall think anything of this kind about thee; and this is altogether in thy power. For who is he that shall hinder thee from being good and simple? Do thou only determine to live no longer unless thou shalt be such. For neither does reason allow [thee to live], if thou art not such.[C] [A] Nothing is known of Satyron or Satyrion; nor, I believe, of Eutyches or Hymen. Euphrates is honorably mentioned by Epictetus (iii. 15, 8; iv. 8, 17). Pliny (Epp. i. 10) speaks very highly of him. He obtained the permission of the Emperor Hadrian to drink poison, because he was old and in bad health (Dion Cassius, 69, c. 8). [B] Crito is the friend of Socrates; and he was, it appears, also a friend of Xenophon. When the emperor says "seen" ([Greek: idôn]), he does not mean with the eyes. [C] Compare Epictetus, i. 29, 28.
