Ira Flatow moderates an Oxford-style debate, with one side proposing and the other side opposing a sharply-framed motion. Proposed topic: We should legalize the market for human organs. Leading thinkers and authorities on the issues argue on each side of the motion. After the formal arguments, the debate is thrown open to the floor for questions, triggering a lively interchange among the speakers and audience members. The live audience will vote on the motion both before and after hearing the arguments, so there is a clear measure of how far people have actually been swayed.
