Gorgias's Thought: An Epistemological Reading is the first monograph published in English entirely devoted to Gorgias's epistemological thought and provides a new perspective on Gorgias's thought more broadly.

The book aims to undermine the common idea that Gorgias is either an orator uncommitted to any conception of truth, or a thinker whose interest is confined to the philosophy of language. It considers his major texts—On What is Not, or On Nature, The Apology of Palamedes and The Encomium of Helen—emphasising the originality and specificity of Gorgias' thought. In combining a philological analysis with substantive use of contemporary epistemological approaches, Di Iulio shows that Gorgias is to be considered first and foremost an epistemologist.

Gorgias's Thought: An Epistemological Reading is of interest to students, scholars and specialists in ancient thought, epistemology, history of philosophy and rhetoric.
