The Republic is Plato's masterwork. It was written 2,400 years ago and remains one of the most widely read books in the world, famous for both the richness of its ideas and the virtuosity of its writing. Presented as a dialogue between Plato's teacher Socrates and various interlocutors, it is an exhortation to study philosophy, inviting its readers to reflect on the choices we must make if we are to live the best life available to us. This complex, dynamic work creates a picture of an ideal society governed not money, power, or fame, but by philosophy, wisdom, and justice.
