It is not likely that Zeno wrote dialogues, though certain references in Aristotle have been supposed to imply this. In the _Physics_[861] we hear of an argument of Zeno’s, that any part of a heap of millet makes a sound, and Simplicius illustrates this by quoting a passage from a dialogue between Zeno and Protagoras.[862] If our chronology is right, there is nothing impossible in the idea that the two men may have met; but it is most unlikely that Zeno should have made himself a personage in a dialogue of his own. That was a later fashion. In another place Aristotle refers to a passage where “the answerer and Zeno the questioner” occurred,[863] a reference which is most easily to be understood in the same way. Alkidamas seems to have written a dialogue in which Gorgias figured,[864] and the exposition of Zeno’s arguments in dialogue form must always have been a tempting exercise. It appears also that Aristotle made Alexamenos the first writer of dialogues.[865] Footnote 861: Arist. _Phys._ Η, 5. 250 a 20 (R. P. 131 a). Footnote 862: Simpl. _Phys._ p. 1108, 18 (R. P. 131). If this is what Aristotle refers to, it is hardly safe to attribute the κεγχρίτης λόγος to Zeno himself. It is worth noting that the existence of this dialogue is another indication of Zeno’s visit to Athens at an age when he could converse with Protagoras, which agrees very well with Plato’s representation of the matter. Footnote 863: Arist. _Soph. El._ 170 b 22 (R. P. 130 b). Footnote 864: Chap. V. p. 231, _n._ 512. Footnote 865: Diog. iii. 48. It is certain that the authority whom Diogenes follows here took the statement of Aristotle to mean that Alexamenos was the first writer of prose dialogues. Plato gives us a clear idea of what Zeno’s youthful work was like. It contained more than one “discourse,” and these discourses were subdivided into sections, each dealing with some one presupposition of his adversaries.[866] We owe the preservation of Zeno’s arguments on the one and many to Simplicius.[867] Those relating to motion have been preserved by Aristotle himself;[868] but, as usual, he has restated them in his own language. Footnote 866: Plato, _Parm._ 127 d. Plato speaks of the first ὑπόθεσις of the first λόγος, which shows that the book was really divided into separate sections. Proclus (_in loc._) says there were forty of these λόγοι altogether. Footnote 867: Simplicius expressly says in one place (p. 140, 30; R. P. 133) that he is quoting κατὰ λέξιν. I now see no reason to doubt this, as the Academy would certainly have a copy of the work. If so, the fact that the fragments are not written in Ionic is another confirmation of Zeno’s residence at Athens. Footnote 868: Arist. _Phys._ Ζ, 9. 239 b 9 sqq. [Sidenote: Dialectic.]
