The Republic of Plato. In ten books. Translated from the Greek by H. Spens, D.D. With a preliminary discourse concerning the philosophy of the ancients by the translator.

The Republic is Plato's most famous work and one of the seminal texts of Western philosophy and politics. The characters in this Socratic dialogue - including Socrates himself - discuss whether the just or unjust man is happier. They are the philosopher-kings of imagined cities and they also discuss the nature of philosophy and the soul among other things.
