Abstract

It is argued that the true definition of justice in Plato’s Republic appears not in Book IV but in Book I, where it is clear that justice is other-oriented or external rather than internal as per Book IV. Indeed, on Book IV’s definition, there is virtually no difference between justice and moderation. Considered here is a single argument between Socrates and Thrasymachus, in which Socrates contends that imperfect injustice is “stronger” than perfect. Rather than producing a just group, the justice between members of a group strengthens the injustice of a group whose external project is already unjust.
