Western philosophy's story starts with a death sentence: Socrates in Athens in 399 BC, condemned for corrupting the young and forced to drink hemlock. The film picks up from that scene and moves forward through the centuries, tracing how his student Plato and Plato's student Aristotle built systems that shaped medieval and modern thought, and carrying the line through to twentieth-century figures like Bertrand Russell. Along the way it stops at the major shifts in how philosophers have asked their questions, from the nature of virtue and the ideal state to logic, knowledge, and the place of reason in a changing world. Rather than treating the subject as a list of names and dates, it presents philosophy as an ongoing argument, each thinker responding to the ones before. The pace is broad and introductory, suited to someone with no background, using narration to connect the dots between eras that are usually taught separately.
