Thrasymachus: Socrates Responds

Socrates responds to Thrasymachus by examining the crafts. A doctor, qua doctor, aims at the health of the patient, not his own profit. A ship's captain, qua captain, aims at the safety of the voyage, not personal gain. If ruling is an art, doesn't it too aim at the good of those ruled? Thrasymachus resists: the real shepherd fattens sheep to slaughter them! Socrates presses: but insofar as he is a shepherd (not a businessman), he cares for sheep. The debate turns to whether injustice is more profitable than justice. Thrasymachus praises the successful tyrant; Socrates argues that injustice creates faction and internal conflict. At the end, Thrasymachus is silenced but not convinced - and Socrates admits his answer is incomplete.
