While the early Platonic dialogues have often been explored and appreciated for their ethical content, the characteristc features of these dialogues are decidedly epistemological - Socrates' method of questions and answers, known as elenchos, Socrates' fascination with definition, Socrates' profession of ignorance, and Socrates' thesis that virtue is knowledge. Benson here attempts to uncover the epistemological view that underlies these previously neglected features of Socratic thought.
