Sartre's Terrifying Gift of Freedom

In this lecture, Lee Braver examines Jean-Paul Sartre's existentialist philosophy and its dramatic implications for ethics. Starting with the famous claim that existence precedes essence, Braver uses Sartre's knife analogy to show how artifacts have built-in purposes but humans do not. Without a divine creator or a natural telos, there is no predetermined human nature and therefore no ready-made moral code to follow. Braver traces how Sartre dismantles the shared assumption behind Mill, Kant, and Aristotle's ethics, then turns that same lens on Socrates himself. He reinterprets Socratic aporia not as a failure but as the real answer: there simply are no universal moral truths waiting to be discovered. The lecture explores bad faith, the French Resistance, the Abraham and Isaac story, and the Nuremberg trials to illustrate Sartre's insistence on radical, inescapable freedom. True ethical maturity, Sartre argues, means acting without guarantees and refusing to let anyone else dictate your choices.
