In Book 1 of Plato’s Republic, Thrasymachus contends two major claims: (1) justice is the advantage of the stronger, and (2) justice is the good of the other, while injustice is to one’s own profit and advantage. In the beginning of Book II, Glaucon self-proclaims that he will be representing Thrasymachus’ claims in a better way, and provides a story of how justice has originated from a state of nature situation. However, Glaucon’s story of the origin of justice has an (...) implication that justice is the advantage of the weak rather than the stronger. This is inconsistent with Thrasymachus’ first claim which states that justice is the advantage of the stronger. This is a problem for Glaucon since Glaucon is supposed to be representing Thrasymachus’ original claims in a better way. In this paper, I provide two solutions to this puzzle with the help of elementary game theory. (shrink)

This paper explores in detail Gorgias' defense of rhetoric in Plato 's Gorgias, noting its connections to earlier and later texts such as Aristophanes' Clouds, Gorgias' Helen, Isocrates' Nicocles and Antidosis, and Aristotle's Rhetoric. The defense as Plato presents it is transparently inadequate; it reveals a deep inconsistency in Gorgias' conception of rhetoric and functions as a satirical precursor to his refutation by Socrates. Yet Gorgias' defense is appropriated, in a streamlined form, by later defenders of rhetoric such as Isocrates (...) and Aristotle. They present it as an effective reductio against a critique of rhetoric that depends on the "harm criterion." This is puzzling, since Plato 's own critique of rhetoric does not depend on the harm criterion. On the other hand, Plato does seem to embrace the harm criterion as a more general principle—as if pre-emptively embracing the reductio —in his arguments about the good in the Meno and Euthydemus. Nonetheless, Isocrates and Aristotle seem to be deliberately misreading Plato on rhetoric: where he intends to criticize its intrinsic nature, they respond as if he were merely complaining about its contingent effects.

In the first part of this paper I argue that beauty and goodness are at least coextensive for Plato. That means that at least with respect to concrete particulars, everything that is good is beautiful and everything that is beautiful is good. Though the good and the beautiful are coextensive, there is evidence that they are not identical. In the second part of the paper I show significance of this relation. In ethics it implies that the good is the right. (...) It also allows one to see how platonists can believe that goodness exists in mathematics. And it explains the usefulness of mathematics in moral education. (shrink)

Bruno Latour has been attempting to transform his sociological account of science into an ambitious theory of democracy. In a key early moment in this project, Latour alleges that Plato’s Gorgias introduces an impossibly ratio-nalistic and deeply anti-democratic philosophy which continues to this day to distort our understandings of science and democracy. Latour reckons that if he can successfully refute the Gorgias , then he will have opened up a space in which to authorize his own theory of democracy. I (...) argue that Latour’s refutation of the Gorgias is a failure. Hence, his political theory is, by his own standards, horribly underdetermined. I present another reading of the Gorgias , and consider the dialogue’s possible relevance for current theories of deliberative democracy. Key Words: Latour • Gorgias • Socrates • rhetoric • elenchus • deliberative democracy. (shrink)
