The aim of this work is to promote a discussion based on differents approaches to Gorgias’s thought, trying to understand it through the following divisions: in the first chapter, we analyze the most important elements attributed to Gorgias’s rhetoric by Plato, through the analysis of Plato’s Gorgias. In the second chapter we undertake a theoretical analysis of his most important texts - Encomium to Helen, On Not Being and Palamedes - based on a reading that recognizes a unity of thought in them. After that, we make use of an important analysis of a rhetoric tradition, emphasizing the principal aspects regarding the creation and the development of rhetoric in Greece in the Vth and IVth centuries BC. In summary, we have taken, from the three main approaches showed and analyzed during this work, the questions that allow us to identify Gorgias’s thought, and to attribute to his activity the name of rhetoric, although in an enlarged conception of this concept.
