n 427 B.C., the Ancient Greek city-state of Athens was flourishing. Approximately 80 years earlier, the Athenians had formed the first self-representative democracy in history, the Peloponnesian War against Sparta had only just started, and Socrates was only beginning to lay the foundation of what would become Western philosophy. That year Plato was born to a wealthy family: with an uncle who was close friends with Socrates, Plato was seemingly destined to become a philosopher. By the end of his life, Plato had indeed become the foremost philosopher of his time, and perhaps the most famous philosopher in Western history. In Plato's Euthyphro, Socrates and Euthyphro, who claims to be a religious expert, attempt to nail down the defition of piety.
