Beber ou não beber? Qual é a questão? Duas leituras de República IV, 439c2-d8

In this paper, I explore two possible readings of Republic IV, 439c2-d8, and of Plato’s claim that the just soul is governed by its rational element. My aim is to argue against a “desiderative” interpretation of the passage, according to which the motivational strength of rational desires depends on a set of desires given in advance and produced independently of reason. As an alternative, I advance a “cognitivist” reading according to which the rational desires of the just soul have as its ultimate source a knowledge about the nature of goodness and happiness, with its own motivational force. Finally, I argue for a reinterpretation of 439a4-b1, a passage that, at first sight, seems to contradict my analysis of 439c2-d8
