Jean-Yves Béziau

Béziau works in the field of logic—in particular, paraconsistent logic, the square of opposition and universal logic. He holds a Maîtrise in Philosophy from Pantheon-Sorbonne University, a DEA in Philosophy from Pantheon-Sorbonne University, a PhD in Philosophy from the University of São Paulo, a MSc and a PhD in Logic and Foundations of Computer Science from Paris Diderot University.

Béziau is the editor-in-chief of the journal Logica Universalis[1] and of the South American Journal of Logic—an online, open-access journal—as well as of the Springer book series Studies in Universal Logic.[2][3] He is also the editor of College Publication's book series Logic PhDs[4]

He has launched four major international series of events: UNILOG (World Congress and School on Universal Logic), SQUARE (World Congress on the Square of Opposition), WOCOLOR (World Congress on Logic and Religion), LIQ (Logic in Question).[5][6]

Béziau created the World Logic Day on January 14, 2019 [7] and successfully submitted the proposal [8] to have this day in the UNESCO Calendar of International days.[9]

In 2014, the academic journal Synthese published an article in which Béziau links "logical pluralism" to homosexuality and complains about the "absurdity and hypocrisy" of "political correctness":[10]

To be pluralist is a politically correct way of being. The expression politically correct has progressively flourished during the last 30 years. It is now being used to characterize what is correct or not in the same sense than morally correct was used before. Moralism now looks quite old-fashion, but politically correct is just a new skin for the old ceremony. What is correct or not has changed but the correctness mood is the same: political correctness shares with the old-fashioned moralism the same blind normative aspect. One has to think or behave in a way without really understanding why and if one disobeys she is considered as an eccentric or/and a dangerous female. And political correctness like the old moralism is full of absurdity and hypocrisy: for example, it is not politically correct to eat dogs; at the same time it is politically correct to eat cows; although it is politically correct to recognize the plurality of religions, the fact that for Hindus eating cows is not good. (p.1948)
