This book investigates the complex relationship between Protagoras, a prominent Sophist, and the concept of 'logos' within the context of ancient Greek philosophy and rhetoric. Edward Schiappa, drawing on his expertise in rhetoric and classical studies, examines the philosophical underpinnings and rhetorical strategies employed by Protagoras. The study analyzes primary texts and secondary scholarship to reconstruct Protagoras's contributions to the understanding of speech, argument, and persuasion in the 5th century BCE.

This scholarly work is recognized for its in-depth analysis of Protagoras and his seminal role in the development of Western thought, particularly concerning rhetoric and philosophy. Scholars in classical studies and rhetoric appreciate its rigorous engagement with primary sources and its contribution to understanding the Sophists' intellectual legacy. The book is considered a significant resource for those studying ancient Greek philosophy and the origins of rhetorical theory.
