1. Describe Thrasymachus' entrance into the dialogue. What's going on here? What sort of person does Thrasymachus seem to be? How does he define justice? Does his definition correspond with his personality?
2. What are the different steps in the debate between Thrasymachus and Socrates? Again, be thorough. Who wins this debate, and why?
3. How does book one end?
(Hint: There is another irony at the very end of book one. What is it?) With what questions does book one end? Has justice been defined yet?
