Abstract
Censure and exclusion of The Republic are characteristics of many utopias, which become dystopias precisely because of turning to them. Plato´s reasons to censure certain types of poetry are ethical and political ones, although his arguments are epistemological . This paper proposes reading these two aspects of the platonic proposal in the light of three specific points of the Timaeus: 1) the theory of discourse about the concept of verisimilar , 2) its relation to the question of whether we can represent objects we do not know, and 3) the demiurge model proposed by Plato in this dialogue. The aim is to show that two of the most problematic aspects of The Republic, are dissolved today in the Timaeus
