Can a statement be simultaneously true and false? That might seem like sheer nonsense to you -- but not to certain modern logicians. In this episode Massimo and Julia are joined again by philosopher and logician Graham Priest, who explains why we have to radically revise our notions of "true" and "false." In the process, he explains classic puzzlers like the "barber paradox": "In a village, the barber shaves all men who do not shave themselves. Does he shave himself?" Follow along for an episode that really takes to heart the podcast's tagline: exploring the borderlands between reason and nonsense.

Rationally Speaking #72 - Graham Priest on Paradoxes and Paraconsistent Logic

Rationally Speaking is the bi-weekly podcast of New York City Skeptics. Join host Julia Galef and guests as they explore the borderlands between reason and nonsense, likely from unlikely, and science from pseudoscience. Any topic is fair game as long as we can bring reason to bear upon it, with both a skeptical eye and a good dose of humor!
We agree with the Marquis de Condorcet, who said that in an open society we ought to devote ourselves to "the tracking down of prejudices in the hiding places where priests, the schools, the government, and all long-established institutions had gathered and protected them."Rationally Speaking was co-created with Massimo Pigliucci, is produced by Benny Pollak, and is recorded in the heart of New York City's Greenwich Village.
