This book offers a new way of looking at the 5th century BCE Sophists, rejecting the bad reputation they have had since antiquity and presenting them as individuals rather than a “movement”, each with his own speciality and personality as revealed through the scant surviving evidence. It provides an account of the Sophists of this period that explains the historical and social developments that led to their prominence and popularity, demonstrating the reasons for their importance and for their seeming disappearance in the 4th century BCE. Restricted to discussion of the few Sophists for whom there are surviving quotations or other texts, The Sophists avoids generalizations often found in other books. It contains accurate translations of most of the surviving material, which forms the securest possible basis for understanding the Sophists as individuals in their various roles, not only as educators but also as ambassadors and pioneers in other fields. After a general introduction, the following chapters present each of the Sophists individually, followed by three chapters which present topics treated by more than one Sophist, such as Logos, Definition and the Nomos-Phusis contrast. The final three chapters reveal the way three important intellectuals of the fourth century (Plato, his rival Isocrates and Aristotle) dealt with the Sophists. An appendix contains several longer passages or works in their entirety in translation, allowing readers to have access to the original source materials and develop their own interpretations. This thorough treatment of the fifth-century Sophists is of interest to scholars working on the subject and on ancient Greek philosophy more broadly, while also being accessible to undergraduate students and the general public interested in the topic.
