For more than two millennia, philosophers have grappled with life's most profound and "eternal" questions. It is easy to forget, however, that these questions about fundamental issues like justice, injustice, virtue, vice, or happiness were not always eternal. They once had to be asked for the first time.

This was a step that could place the inquirer beyond the boundaries of the law. And the Athenian citizen and philosopher who took that courageous step in the 5th century B.C. was Socrates.

In this intellectually vibrant - yet crystal-clear and accessible - series of 36 lectures, an award-winning teacher provides you with a detailed analysis of the golden age of Athenian philosophy and the philosophical consequences of the philosopher's famed "Socratic Turn": his veering away from philosophy's previous concerns with the scientific study of nature and the physical world and toward the scrutiny of moral opinion. After Socrates, philosophy would never be the same. You learn that much of Socrates's philosophy is captured in the writings of his contemporaries and followers, including not just Plato and Aristotle, but also figures like Xenophon, a great thinker and military commander, and the comic playwright Aristophanes. Professor Bartlett takes you through Plato's most important dialogues - where Socrates is the protagonist - and shows how they convey the core of Socrates's philosophy. He then moves on to Aristotle, who did more than anyone to establish a comprehensive system of philosophy in the West, producing work encompassing morality, politics, aesthetics, logic, science, rhetoric, theology, metaphysics, and more.
