SPEAKING OF PARADOXES

Audio available soon.
Paradoxes have baffled philosophers and logicians for two millennia, potentially undermining the very foundations of logic and rationality. Consider the famous (or infamous) Liar paradox: "This sentences is not true." Well, if it is true, it is not; and if it is not, it is true. So it seems to be both true and not true. But that violates the principle of non-contradiction, a fundamental pillar of logic. What gives? Prof. Graham Priest from the City University of New York thinks he's got the answer. He has invented a whole new logical system, called paraconsistency, to resolve the problems posed by paradoxes. Join us for an accessible explanation of the surprising consequences of exploring the borderlands of logic."
Graham Priest is Boyce Gibson Professor of Philosophy at the University of Melbourne and a distinguished professor of philosophy at the CUNY Graduate Center. He is known for his in-depth analyses of the logical paradoxes, and his many writings related toparaconsistent and other non-classical logics. In addition to his work in philosophy and logic, Priest practices Karate-do. He is 3rd Dan, International Karate-do Shobukai; 4th Dan, Shi’to Ryu, and an Australian National Kumite Referee and Kata Judge. So there.
