Second episode (Season 2) of a series of talks with the logician and philosopher Graham Priest (CUNY) about contradiction. Since the lier paradox made its first appearance in Ancient Greece, there have been countless attempts to solve it. In this episode Prof. Priest discusses some of them and explains why they fail. He concludes that we should take these paradoxes as evidence that some contradictions are true.
