Greg Restall: Objections to Logical Pluralism and the Preface and Liar Paradoxes | WSB #17

December 5, 2017

In the first half of my interview with Professor Greg Restall, he laid out logical pluralism: the view that there is more than one correct logical consequence relation. In this second half, he responds to objections. Specifically, he explains why it makes sense to admit inconsistent situations even if one believes, as he does, that all possible worlds are consistent. He also touches on the relationship between notions of deductive validity and reasoning norms. We then take an extended detour into the Preface paradox, the Liar paradox, dialetheism, and the relationship between proof theory and philosophy.

Next week: Tomasz Kaye, Pt. 1: Foundations for Political Philosophy
