Plato’s Protagoras contains, among other things, three short but puzzling remarks on the media of philosophy. First, at 328e5–329b1, Plato makes Socrates worry that long speeches, just like books, are deceptive, because they operate in a discursive mode void of questions and answers. Second, at 347c3–348a2, Socrates argues that discussion of poetry is a presumptuous affair, because, the poems’ message, just like the message of any written text, cannot be properly examined if the author is not present. Third, at 360e6–361d6, (...) it becomes clear that even if the conversation between Socrates and Protagoras was conducted by means of short questions and answers, this spoken mode of discourse is problematic too, because it ended up distracting the inquiry from its proper course. As this paper 2 sets out to argue, Plato does not only make Socrates articulate these worries to exhibit the hazards of discursive commodifi cation. In line with Socrates’ warning to the young Hippocrates of the dangers of sophistic rhetoric, and the sophists’ practice of trading in teachings, they are also meant to problematize the thin line between philosophical and sophistical practice. By examining these worries in the light of how the three relevant modes of discourse are exemplifi ed in the dialogue, this paper aims to isolate and clarify the reasons behind them in terms of deceit, presumptuousness and distraction; and to argue that these reasons cast doubts on the common assumption that the dialogue’s primary aim is to show how sophistical rhetoric must succumb to Socratic dialectic.

Abstract The main thesis of the paper is that, in the coda to the Protagoras (360e-end), Plato tells us why and with what justification he demands a definition of virtue: namely, in order to resolve a particular aporia . According to Plato's assessment of the outcome of the arguments of the dialogue, the principal question, whether or not virtue can be taught , has, by the end of the dialogue, emerged as articulating an aporia , in that both protagonists, Socrates (...) and Protagoras, have argued equally on both its sides. The first part of the paper provides an extensive analysis of the coda, with the aim of establishing the main thesis. The second part provides a comprehensive review of the arguments in the dialogue, with the aim of determining whether their outcome is what Plato says in the coda that it is. I undertake this review in three steps: on Plato's conception of reasons (logoi); Socrates' arguing on both sides; and Protagoras' arguing on both sides. (shrink)
