Despite the extensiveness of top-down control in his ideal city, Plato takes seriously the idea that the market does not require total regulation via legislation and that participants in the market may be capable of self-regulation. This paper examines the discussion of market regulation in the Republic and argues that the philosopher rulers play a very limited role in regulating market activities. Indeed, they are concerned only with averting excesses of wealth and poverty. The rules and regulations that are foundational to the daily functioning of the market – enforcement of contracts, resolution of disputes, etc. – are endogenous to the market participants themselves. In allowing for this self-regulation, Plato expresses tempered optimism about the market and a profound confidence in his ideal city’s educational program.

The second conjunct of the Republic’s account of justice—that justice is “not meddling in the work of another”—has been neglected in Plato literature. This paper argues that the conjunct does more work than merely reiterating the content of the first conjunct—that justice is “doing one’s own work.” I argue that Socrates develops the concept at work in this conjunct from its introduction with the Principle of Specialization in Book II to its final deployment in the finished conception of justice in Book IV. Crucial to that concept’s development is the way in which the notion of “another” comes to refer to members of distinct classes or parts, i.e. takes on an inter-part connotation beyond a mere intra-part connotation. The first conjunct—that justice is “doing one’s own work”—does not connote the same divisions, and so the conjuncts should not be understood as equivalent or mutually entailed.

the standard reading of plato's Republic is that justice is predicated of the ideal city and of the philosophers, and that all other constitutions, both psychic and political, that are mentioned in the course of the dialogue are in some way or another defective and unjust. A non-standard reading appears to be gaining traction, however. Unorthodox Plato commentators such as Silverman, Jonas, Nakazawa, Braun, and Rowe argue that the ideal city—lovingly named 'Kallipolis'—is not just, that it is merely an improvement upon, but not a complete cure for, the Luxurious City that is described immediately before it.1 If we want to gaze upon a just city, these unorthodox commentators propose, look no farther than the City of...
