EPISTEMIC MULTILATERAL LOGIC

open access: yesThe Review of Symbolic Logic, 2020
AbstractWe presentepistemic multilateral logic, a general logical framework for reasoning involving epistemic modality. Standard bilateral systems use propositional formulae marked with signs for assertion and rejection. Epistemic multilateral logic extends standard bilateral systems with a sign for the speech act of weak assertion (Incurvati & ...
