Utopia.

First published in 1516, Thomas More's Utopia is one of the most important works of European humanism. Through the voice of the mysterious traveler Raphael Hythloday, More describes a pagan, communist city-state governed by reason. Addressing such issues as religious pluralism, women's rights, state-sponsored education, colonialism, and justified warfare, Utopia seems remarkably contemporary nearly five centuries after it was written, and it remains a foundational text in philosophy and political theory.
