The Efficacy of True Speech Gorgias Between Rorty and Foucault

Abstract

According to a widespread interpretation, in Gorgias’ philosophy of language there is no room for truth at all. The only aim of logos for him would be effective persuasion and speech would be constrained by nothing but persuasiveness itself. Referring to Encomium of Helen, I try to point out, however, that in Gorgias there is an attempt to investigate the complex relationship between truth and efficacy in the functioning of language. I also suggest that, seen from this perspective, Gorgias’ conception of truth shows significant points of contact with Rorty’s and, above all, Foucault’s thinking.
