"Plato's Theaetetus: On the Way of the Logos," Review of Metaphysics, 51, no. 1 (September 1997): 25-53. Reprinted in The Argument of the Action, 2000.
The opening of the Theaetetus is curious. The report we have of another opening of nearly the same length indicates that it was always a curiosity. If both openings are Plato’s, and the rest of the dialogue they preface were not different, then Plato changed his mind about how to start off the trilogy to which the Theaetetus belongs. If the second version is spurious, however, then we cannot hope to interpret it. If we assume its genuineness and that it represents Plato’s only or final recension — the other one is said to be spurious and rather frigid — then the Theaetetus opens with our listening in on a recital of the conversation Socrates had with Theaetetus opens with our listening in on a recital of the conversation Socrates had with Theaetetus and Theodorus shortly before his death, while we supposedly are hearing it in Megara many years after the conversation occurred.
