This introductory talk offers an overview of the historical development of paraconsistent logics, from Jaśkowski’s discussive logic D2 and da Costa’s hierarchy of Cn systems to the contemporary Logics of Formal Inconsistency (LFIs). The emergence of the Brazilian school of paraconsistency and its epistemic approach to paraconsistency are also discussed.
2. Paraconsistent Epistemology
In this second session we will examine how paraconsistent agents can reason. The relationship between knowledge and paraconsistency is explored in depth through multi-modal epistemic extensions of LFI1, a three-valued LFI. The combination of paraconsistency and epistemic logic broadens the range of epistemic possibilities, and these novel epistemic states are analyzed in detail.
3. The Dynamic Turn in Paraconsistency
The final session investigates the notions of change and time in relation to paraconsistency. By integrating perspectives from two major traditions—the Brazilian school of logic and the Dutch school of logic—the idea of a dynamic turn in paraconsistency is introduced. Dynamic epistemic and dynamic temporal extensions of LFI1 are presented and illustrated with examples.
