In this paper, I oppose the now-dominant view that Thrasymachus offers a definition of justice in Book I of the Republic. This way of interpretation Thrasymachus does not pay sufficient attention to the methodological assumptions he makes during his disagreement with Socrates. To better understand Socrates’ antagonist, it is crucial to remember that he was, in fact, a sophist. I argue that what the character Thrasymachus is doing in Book I is importantly akin to a certain genre of sophistic arguments (...) from the 5th century. In his discussion with Socrates, Thrasymachus attempts a genealogical unmasking of justice, which he hopes will change the action-guiding beliefs of his audience. Although my discussion is primarily about the methodology or structure of Thrasymachus’ argument, I conclude by offering a brief discussion of its substance, as well. (shrink)

In the 5th century a number of sophists challenged the orthodox understanding of morality and claimed that practicing injustice was the best and most profitable way for an individual to live. Although a number of responses to sophistic immoralism were made, one argument, in fact coming from a pair of sophists, has not received the attention it deserves. According to the argument I call Immortal Repute, self-interested individuals should reject immorality and cultivate virtue instead, for only a virtuous agent can (...) win the sort of everlasting reputation that makes a life truly admirable and successful.

A growing number of scholars have seen that the Republic’s division of goods includes goods which possess value δι᾽ αὑτό in virtue of some of their causal effects. Building on this, I argue that goods, including justice, which are valuable διὰ τὰ γιγνόµενα ἀπ’ αὐτοῦ (and whose effects can contribute to the value a good has δι᾽ αὑτό) are so in virtue of a limited class of beneficial effects: those that depend on the recognition of other agents. This way of (...) dividing goods explains why Socrates legitimately invokes some effects of justice in his demonstration that justice is valuable δι᾽ αὑτό. (shrink)

Abstractabstract:This paper offers a new interpretation of courage in Plato's Republic. Despite the attention that this dialogue has received in the past, scholars have been disinclined to explore the metaphysics of the virtues. I argue that courage is, by its very nature, a δύναμις of the sort described in book 5. In particular, I argue that courage is the power over reason's correct practical deliberations about what one ought to do and that it accomplishes the preservation of these deliberations in (...) the face of appetitive threats. I then explore the implications this has for the moral psychology of the virtuous agent and the question of who can be genuinely courageous. (shrink)
