“Arts Which Achieve Their Object Through Silence”

Abstract

Ι analyse a limited section in the conversation between Socrates and Gorgias in Plato’s Gorgias (449e1-451d8). The significance of this section has been overlooked in the scholarly literature; I shall argue that the passage draws attention to Gorgias’ confused treatment of λόγοι as both the instrumentum and the materia of rhetoric. Whether Gorgias is aware of the distinction or not, he is driven by Socrates de facto to look for a materia of rhetoric that is not to do with λόγοι, since Socrates increasingly treats λόγοι effectively as the instrumentum of rhetoric. Socrates manipulates Gorgias through a combination of content and form, using λόγοι and λόγος in a variety of cases with a number of prepositions, from περὶ λόγους, to διὰ λόγων, διὰ λόγου, ἐν λόγοις, and eventually λόγῳ, to distance speaking and speeches themselves from the materia of rhetoric.
