Readers of the Republic have usually seen the passages about the stereotypical characteristics of communities as grounding the city-soul analogy. Plato indeed takes those attributions to be a powerful reason to expect the same types (εἴδη) and manners (ἤθη) in both the city and the individual soul and, hence, to affirm the structural isomorphism of polis and psyche (Resp. 435e). This natural reading is considerably challenged by Bernard Williams’ “The Analogy of City and Soul in Plato’s ‘Republic’” (2001), where it is shown to entail paradoxes that make the analogy flawed. The point lies in the derivation principles that communal stereotypes imply. For while a community is expected to be, say, spirited precisely because all or many or its most prominent members are spirited, it seems that Plato’s perfect and imperfect constitutions fail to meet this simple requirement. In this paper, I will briefly examine Williams’ puzzles and lay out their core challenges. Then, I will discuss two of the most prominent attempts to meet them: Lear’s psychological interpretation and Ferrari’s metaphorical interpretation of the city-soul analogy. As I hope to show, they both entail consequences that run against some of the Republic’s most important aims or make them plainly unattainable. Finally, by distinguishing psycho-political forces (ἤθη) from psycho-political constitutions (εἴδη), I propose a solution that holds the derivation rules without falling prey to Williams’ paradoxes. This solution, we will see, calls for a prima facie compelling model of the unity of virtues, that is, a model showing how everyone in Callipolis may possess, in some way, all the virtues.
