 In what follows, citations to passages in Plato use “Stephanus pages,” based on a sixteenth-century edition of Plato’s works. The page numbers in that edition, together with the letters a–e, have become standard. Almost every translation of Plato includes the Stephanus page numbers and letters in the margins, or at the top of the page. Thus, “Symposium 204b” refers to the same brief passage in every edition and every translation of Plato.
