More than 2,000 years later, Plato's Republic remains astonishingly relevant to our everyday lives. It poses one question after another that might well have been drawn from the headlines and debates of our nation's recent history: What sort of person should rule the state? Are all citizens equal before the law? Should everyone have equal access to health care? Plato's greater inquiry, however, was into the question of defining justice itself and the reasons why a person would choose a life aligned with that virtue.

The Roman Republic is one of the most breathtaking civilizations in world history. Between roughly 500 BCE to the turn of the millennium, a modest city-state developed an innovative system of government and expanded into far-flung territories across Europe, Northern Africa, and the Middle East.

Roughly 2,500 years ago, the Athenian people established a radical democracy in which power derived from the votes of everyday citizens. At a time when local governments ranged from oligarchy to tyranny, the elite classes of Athens gradually ceded power to the inexperienced masses, whose votes served as referendums for everything from taxation to war to welfare. The sequence of events that led to this development is astonishing, and the society that flourished under Athenian democracy is one of the greatest - even if greatly flawed - achievements in world history.

Mesopotamia is the ancient name for the region that is now Iraq, a remarkably advanced civilization that flourished for two-thirds of the time that civilization has existed on Earth. Mesopotamians mastered irrigation agriculture; built the first complex urban societies; developed writing, literature, and law; and united vast regions through warfare and diplomacy. While civilizations like Greece and Rome have an unbroken tradition of written histories, the rich history of Mesopotamia has only been recently rediscovered, thanks to the decipherment of Mesopotamia's cuneiform writing less than 200 years ago.
