In Plato's Euthydemus, Socrates claims that the possession of epistēmē suffices for practical success. Several recent treatments suggest that we may make sense of this claim and render it plausible by drawing a distinction between so-called “outcome-success” and “internal-success” and supposing that epistēmē only guarantees internal-success. In this paper, I raise several objections to such treatments and suggest that the relevant cognitive state should be construed along less than purely intellectual lines: as a cognitive state constituted at least in part (...) by ability. I argue that we may better explain Socrates' claims that epistēmē suffices for successful action by attending to the nature of abilities, what it is that we attempt to do when acting, and what successful action amounts to in the relevant contexts. These considerations suggest that, contrary to several recent treatments, the success in question is not always internal-success. (shrink)

In defending the view that justice is the advantage of the stronger, Thrasymachus puzzlingly claims that rulers never err and that any practitioner of a skill or expertise (τέχνη) is infallible. In what follows, Socrates offers a number of arguments directed against Thrasymachus’ views concerning the nature of skill, ruling, and justice. Commentators typically take a dim view of both Thrasymachus’ claims about skill (which are dismissed as an ungrounded and purely ad hoc response to Socrates’ initial criticisms) and Socrates’ (...) latter arguments (which are deemed extremely weak). In this paper, I clarify Thrasymachus’ views (and those of several other ancients) concerning qua locutions and the nature of skill and ability and I reconstruct Socrates’ arguments against Thrasymachus’ views concerning skill and justice. I argue that Thrasymachus’ views are not ungrounded or ad hoc and that Socrates’ arguments are rather different (and significantly stronger) than often supposed. (shrink)

AtCategories7, 6a36-7 Aristotle defines relatives, but at 8a13-28 worries that the definition may include some substances. Aristotle introduces a second account of relatives to solve the problem. Recent commentators have held that Aristotle intends to solve the extensional adequacy worry by restricting the extension of relatives. That is, R2 counts fewer items as relative than R1. However, this cannot explain Aristotle’s attitude to relatives, since he immediately returns to using R1. I propose a non-extensional reading. R1 and R2 do not (...) specify different sets of relatives, but rather different ways to understand each relative. (shrink)
