Parmenides

Thereupon we started, and we found Antiphon at home, giving a smith an order to make a bridle. When he had got rid of the smith and his brother told him what we were there for, he remembered me from my former visit and greeted me cordially, and when we asked him to repeat the conversation, he was at first unwilling—for he said it was a good deal of trouble—but afterwards he did so. Antiphon, then, said that Pythodorus told him that Zeno and Parmenides once came to the Great Panathenaea; that Parmenides was already quite elderly, about sixty-five years old, very white-haired, and of handsome and noble countenance; Zeno was at that time about forty years of age; he was tall and good-looking, and there was a story that Parmenides had been in love with him. He said that they lodged with Pythodorus outside of the wall, in Cerameicus, and that Socrates and many others with him went there because they wanted to hear Zeno’s writings, which had been brought to Athens for the first time by them. Socrates was then very young. So Zeno himself read aloud to them, and Parmenides was not in the house. Pythodorus said the reading of the treatises was nearly finished when he came in himself with Parmenides and Aristoteles (the one who was afterwards one of the thirty), so they heard only a little that remained of the written works. He himself, however, had heard Zeno read them before. Socrates listened to the end, and then asked that the first thesis of the first treatise be read again. When this had been done, he said: Zeno, what do you mean by this? That if existences are many, they must be both like and unlike, which is impossible; for the unlike cannot be like, nor the like unlike? Is not that your meaning?Yes, said Zeno. Then if it is impossible for the unlike to be like and the like unlike, it is impossible for existences to be many; for if they were to be many, they would experience the impossible. Is that the purpose of your treatises, to maintain against all arguments that existences are not many? And you think each of your treatises is a proof of this very thing, and therefore you believe that the proofs you offer that existences are not many are as many as the treatises you have written? Is that your meaning, or have I misunderstood?
