The essay seems, at the first glance, to be put in the form of a dialogue, but it is about as much of a dialogue as Quiller-Couch’s Foe-Farrell. The dialogue form is merely a literary subterfuge to present an essay in a slightly more attractive form, and the third person of the dialogue, only occasionally recalled to the reader by the parsimonious interjection of he said, may be presumed to be Plutarch, the author. The two speakers in the brief dialogue at the beginning of the essay are Moschion, a physician, whom Plutarch introduces also into the Symposiacs (Moralia, 658 a), and Zeuxippus, a friend of Plutarch’s, who is introduced also as a speaking character in two other essays of Plutarch’s (Moralia, 748 e and 1086 c), besides being mentioned several times in other essays.
The title of the essay is included in Lamprias’ list of Plutarch’s works, and Stobaeus, in his Florilegium, has several quotations from it, sometimes with a slightly different reading, but none of these readings changes the meaning of the passage at all, and rarely is one to be preferred to the reading found in the mss. of Plutarch (see Vol. I. Introd. p. xxi).
