Research Topics
Philosophy of non-classical logics in general; Inferentialist reconstruction of the framework of relevant logic; Negation as modal operator; Proof-theoretic semantics based on sequent calculiOverview of the research
I am studying non-classical logic with a philosophical interest. The main topic of my study is relevant logic, one of the major non-classical logics. I am trying to reconstruct the conceptual framework of relevant logic, appealing to Robert Brandom’s inferentialism, according to which the essential feature of our discursive practice is inference, the game of giving and asking for reasons. Another intellectual source of the reconstruction project is Michael Dummett’s proof-theoretic semantics. Giving a twist to it, I am developing a version of proof-theoretic semantics based on sequent calculi. I am also working on the conception of negation as modal operator, which plays an important role in the reconstruction project.
