VII. And he was a very clever arguer; and rejected the theory of species. And he used to say that a person who spoke of man in general, was speaking of nobody; for that he was not speaking of this individual, nor of that one; for speaking in general, how can he speak more of this person than of that person? therefore he is not speaking of this person at all. Another of his illustrations was, “That which is shown to me, is not a vegetable; for a vegetable existed ten thousand years ago, therefore this is not a vegetable.” And they say that once when he was conversing with Crates, he interrupted the discourse to go off and buy some fish; and as Crates tried to drag him back, and said, “You are leaving the argument;” “Not at all,” he replied, “I keep the argument, but I am leaving you; for the argument remains, but the fish will be sold to some one else.” VIII. There are nine dialogues of his extant, written in a frigid style: The Moschus; the Aristippus or Callias; the Ptolemy; the Chœrecrates; the Metrocles; the Anaximenes; the Epigenes; the one entitled To my Daughter, and the Aristotle. IX. Heraclides affirms that Zeno, the founder of the Stoic school, had been one of his pupils. X. Hermippus says that he died at a great age, after drinking some wine, in order to die more rapidly. And we have written this epigram upon him:— Stranger, old age at first, and then disease, A hateful pair, did lay wise Stilpo low. The pride of Megara: he found good wine The best of drivers for his mournful coach, And drinking it, he drove on to the end. And he was ridiculed by Sophilus the comic poet, in his play called Marriages:— The dregs of Stilpo make the whole discourse of this Charinus. LIFE OF CRITO. I. Crito was an Athenian. He looked upon Socrates with the greatest affection; and paid such great attention to him, that he took care that he should never be in want of anything. II. His sons also were all constant pupils of Socrates, and their names were Critobulus, Hermogenes, Epigenes, and Ctesippus. III. Crito wrote seventeen dialogues, which were all published in one volume; and I subjoin their titles:—That men are not made good by Teaching; on Superfluity; what is Suitable, or the Statesman; on the Honourable; on doing ill; on Good Government; on Law; on the Divine Being; on Arts; on Society; Protagoras, or the Statesman; on Letters; on Political Science; on the Honourable; on Learning; on Knowledge; on Science; on what Knowledge is. LIFE OF SIMON. I. Simon was an Athenian, a leather-cutter. He, whenever Socrates came into his workshop and conversed, used to make memorandums of all his sayings that he recollected.
