<blockquote>“Of all existing things some are good, some evil, and some indifferent. Now the good things are virtues and what partakes of them, the evil are vice and what partakes of vice, and the indifferent lie between these: wealth, health, life, death, pleasure, pain. 'How do you know this?' — Hellanicus says so in his Egyptian History. For what difference does it make whether you say that, or that it was Diogenes in his Ethics or Chrysippus or Cleanthes? Have you then investigated any of these matters and formed an opinion of your own? Let me see how you are accustomed to act in a storm at sea. Do you recall this classification when the sail cracks and you cry aloud? If some idle fellow should stand beside you and say: 'Tell me, for Heaven's sake, what you told me before. It isn't a vice to suffer shipwreck, is it? It doesn't partake of vice, does it?' Would you not hurl a stick of wood at him and cry: 'What have we to do with you, fellow? We perish and you come and crack jokes.' But if Caesar should summon you to answer an accusation . . .”
