Democracy thrives on civil debate, Michael Sandel  says -- but we're shamefully out of practice. He leads a fun refresher, with TEDsters sparring over a recent Supreme Court case (PGA Tour Inc. v. Martin) whose outcome reveals the critical ingredient in justice.

The lost art of democratic debate

Engaging in real democratic debate means grappling with the deeper moral questions that underlie hot-button issues like health care, Wall Street bailouts, and same-sex marriage. The Supreme Court's decision on whether a disabled golfer could use a cart hinged on defining the essential purpose of golf, not just fairness. By revisiting Aristotle’s idea that justice depends on understanding purpose and excellence, this approach invites richer, more respectful public discourse. Democracy flourishes when citizens bring their deepest convictions into the open, rather than leaving them at the door.
