Recent years have witnessed a burgeoning interest in the application of substructural logics as a crucial component of philosophically motivated solutions to traditionally intractable paradoxes like the semantic paradoxes and the paradoxes of vagueness. Such solutions have proved to offer new valuable insights into those paradoxes, complementing those provided by more “traditional” non-substructural solutions that also revise classical logic. The workshop proposes to take stock of the current trends in this thriving area of philosophy of logic.
