Philosophical Paraconsistency

Jean-Yves Béziau
Universidade Federal do Rio de Janeiro


In this talk I will discuss how on the one hand we can develop philosophical ideas inspired by paraconsitent logic and how on the other hand we can establish a solid philosophical basis for having meaningful constructions of paraconsistent systems. I will give many different examples and comment a variety of paraconsistent negations.
