The Place: Athens, Greece
One of the greatest teachers in history, Socrates would wander throughout the streets of Athens talking to his fellow citizens about discovering the truth in all things. Socrates gained a following of young men, whom he taught to question everything, including the Athenian military. For this he was arrested on the charges of corrupting the youth, not believing in the gods and creating new deities. This speech acted as his defense as he attempted to persuade his jury with reason. Despite this, he lost and was sentenced to death by hemlock, dying as a martyr for free thinking.
