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.

For Socrates, the virtues are a kind of knowledge, and the virtues form a unity. Sometimes, Socrates suggests that the virtues are all ‘one and the same’ thing. Other times, he suggests they are ‘parts of a single whole.’ I argue that the ‘what is x?’ question is sophisticated, it gives rise to two distinct kinds of investigations into virtue, a conceptual investigation into the ousia and a psychological investigation into the dunamis, Plato recognized the difference between definitional accounts of (...) the ousia and a psychological accounts of the dunamis, and the distinction between these two investigations can effectively resolve various interpretive puzzles regarding the unity of the virtues. It is argued that the virtues are ‘one and the same’ psychologically, while they are ‘parts of a single whole’ conceptually. (shrink)

Intellectualism about human virtue is the thesis that virtue is knowledge. Virtue intellectualists may be eliminative or reductive. If eliminative, they will eliminate our conventional vocabulary of virtue words-'virtue', 'piety', 'courage', etc.-and speak only of knowledge or wisdom. If reductive, they will continue to use the conventional virtue words but understand each of them as denoting nothing but a kind of knowledge (as opposed to, say, a capacity of some other part of the soul than the intellect, such as the (...) will or the appetites). Virtue intellectualists may be pluralists or monists. If pluralist, they identify the virtues with distinct kinds of knowledge. If monist, they identify all the virtues with one and the same kind of knowledge. In a number of dialogues-including the Euthyphro, Apology, Charmides, Euthydemus, Laches, Lysis, Protagoras, and Republic I-Socrates gives arguments that support Reductive Monist Intellectualism (RMI) about human virtue. I disarm an influential objection to RMI as the correct interpretation of Socrates. (shrink)

In the so-called ‘dialogues of definition,’ Socrates appears to endorse the ‘priority of definition.’ This principle states that an agent cannot know anything about F-ness (its instances, examples, properties, etc.) without knowing what F-ness is (the definition of F-ness). Not only is this principle implausible, it is also difficult to square with Socrates’ method. In employing his method, Socrates appeals to truths about the instances and properties of F-ness, even while pursuing definitional knowledge; meanwhile, he holds that one cannot know (...) those truths without already knowing the definition. Thus, there is a tension between Socrates’ principle and his method. Commentators have tried to resolve this problem in various ways, though typically without a careful examination of his ‘What is F-ness?’ question. I argue that Socrates employs the ‘What is F-ness?’ question as a way of introducing two distinct types of investigation into F-ness (conceptual and causal). With this established, the relationship between Socrates’ principle and his method comes to light, and the tension is resolved. (shrink)
