Justice in Plato's Republic : The Lessons of Book 1

In Book 4 of Plato's Republic, Socrates introduces what is regarded by scholars as the Platonic account of justice, according to which it is essentially internal and self-regarding, a matter of relations among the parts of a city or soul.In this book, Roslyn Weiss contends that there is another notion of justice, as other-regarding and external, which is to be found in a series of conversations in Book 1 between Socrates and three successive interlocutors.Weiss considers the relationship between justice as conceived in Book 1 and Book 4, and carefully examines what can be learned from each of the arguments.Her close analysis of Book 1 brings to light what Socrates really believed about justice, and extracts and explores this Book's many insights concerning justice—at both the political and the personal level.
