platonic conception of truth in Republic in light of the predicative truth in the Sophist

Abstract

This paper aims at reconstructing the ontological conception of truth present in Republic V-VI in light of the predicative conceptualization of truth developed in the Sophist. My interpretative hypothesis is that in both dialogues Plato distinguishes the truth from its possibility conditions, in particular, its ontological foundation. I will try to show that the ontological and predicative conceptions of truth in the platonic thought are incompatible because they presuppose different ontologies as their foundations.
