Socrates, Plato, and Aristotle are three of philosophy's greatest contributors. You already knew that. But what you might not know is that they all lived in classical Athens at around the same time. You might not know that Socrates was executed for practicing free speech. You might not know that Plato was sold into slavery for making the Tyrant of Syracuse angry. And you might not know that Aristotle tutored the famous Alexander the Great. The philosophers were part of some crazy world events as well. The Peloponnesian War, the Macedonian takeover, and more...it's all there.
