This book is a rereading of the early dialogues of Plato from the point of view of the people with whom Socrates engages in debate. Existing studies are thoroughly dismissive of the interlocutors and reduce them to the status of mere mouthpieces for views that are hopelessly confused or demonstrably false. This book takes interlocutors seriously and treats them as genuine intellectual opponents whose views are often more defensible than commentators have generally thought.
