Discourses: Book 2 19 : 2
If, then, someone asks me, "But which pair of these do you yourself maintain?" I shall answer him that I do not know; but I have received the following account: Diodorus used to maintain one pair, Panthoides and his group, I believe, and Cleanthes another, and Chrysippus and his group the third. "What, then, is your opinion?" I do not know, and I was not made for this purpose—to test my own external impression upon the subject, to compare the statements of others, and to form a judgement of my own. For this reason I am no better than the grammarian. When asked, "Who was the father of Hector?" he replied, "Priam." "Who were his brothers?" "Alexander and Deïphobus." "And who was their mother?" "Hecuba. This is the account that I have received." "From whom?" "From Homer," he said. "And Hellanicus also, I believe, writes about these same matters, and possibly others like him." And so it is with me about the "Master Argument"; what further have I to say about it? But if I am a vain person, I can astonish the company, especially at a banquet, by enumerating those who have written on the subject. "Chrysippus also has written admirably on this topic in the first book of his treatise On Things Possible. And Cleanthes has written a special work on the subject, and Archedemus. Antipater also has written, not only in his book On Things Possible, but also a separate monograph in his discussion of The Master Argument. Have you not read the treatise?" "I have not read it." "Then read it." And what good will it do him? He will be more trifling and tiresome than he is already. You, for example, what have you gained by the reading of it? What judgement have you formed on the subject? Nay, you will tell us of Helen, and Priam, and the island of Calypso which never was and never will be!
