What ‘If’?

Solutions to the paradoxes of semantic self-reference which endorse the unrestricted T-schema (and cognate principles) normally assume that the conditional involved in the schema is a detachable one (i.e., one that satisfies modus ponens). In a paraconsistent setting, there is another possibility: to take it to be the material conditional. In this talk, I will discuss some of the ramifications of this possibility.

Graham Priest, a Distinguished Professor at CUNY Graduate Center, is the most prominent contemporary champion of dialetheism, the view that some claims can be both true and false. He is known for his in-depth analyses of semantic paradoxes, and his many writings relate to paraconsistent and other non-classical logics. He has taught in Australia at the University of Melbourne since 2001 and has authored numerous books. Over the course of his prominent career, he has published articles in nearly every major journal on philosophy and logic. He has held visiting research positions at many universities, including the Australian National University, the Universities of Cambridge, New York, Pittsburgh, São Paulo, Kyoto, and the Soviet Academy of Sciences. He holds a Ph.D. in mathematics from the London School of Economics.
