In Plato's Lysis, Socrates' conversation with Lysis features logical fallacies and questionable premises and closes with a blatantly eristic trick. I show how the form and content of these arguments make sense if we interpret them from the perspective of Socrates' pedagogical goals. Lysis is a competitive teenager who, along with his friend Menexenus, enjoys the game of eristic disputation. Socrates recognizes Lysis' predilections, and he constructs his arguments to engage Lysis' interests and loves, while also drawing the boy into (...) thinking philosophically about the issues that the arguments raise about love, freedom, and happiness.
