The eminent classical scholar Jacqueline de Romilly offers a compelling reassessment of the intellectual and cultural achievement of the Sophists of classical Athens, who were among the most important and influential thinkers of the ancient world. She provides a vivid reconstruction of their original methods and bold doctrines, arguing that they have been widely misunderstood because of the lack of direct evidence, and she investigates the reasons for their success and for the subsequent reaction against them.
