# On the Methodology of Paraconsistent Logic

## Heinrich Wansing

### Ruhr University Bochum

In this talk I will critically discuss some widely shared methodological assumptions about paraconsistent logic. I will argue that there exist several reasons not to consider classical logic as the reference logic for developing systems of paraconsistent logic and will suggest to weaken a certain maximality condition. Moreover, I will argue that the guiding motivation for the development of paraconsistent logics should be neither epistemological nor ontological, but informational, and I will, from this perspective, discuss the idea of “ex contradictione nihil sequitur”.
