Examines and evaluates Socrates' role as an educator in Plato's dialogues. Despite his ceaseless efforts to purge his fellow citizens of their unfounded opinions and to bring them to care for what he believes to be the most important things, Plato's Socrates rarely succeeds in his pedagogical project with the characters he encounters. This is in striking contrast to the historical Socrates, who spawned the careers of Plato, Xenophon, and other authors of Socratic dialogues. Through an examination of Socratic pedagogy under its most propitious conditions, focusing on a narrow class of dialogues featuring Lysis and Alcibiades, this book answers the question: 'why does Plato portray his divinely appointed gadfly as such a dramatic failure?'
