Logical Pluralism / Paraconsistent Logic
More than one logic may be legitimate, and some systems permit reasoning with contradictions without collapse.
What it claims
Logical pluralism allows multiple legitimate consequence relations. Beall and Restall begin with the requirement that a conclusion be true in every case in which its premises are true. Different appropriate interpretations of cases—worlds, constructions, or situations—motivate classical, intuitionistic, or relevant approaches.
