How to Say 'Yes' or 'No': Logical Approaches to Modes of Assertion and Denial

Assertion and denial are mutually incompatible speech acts. In a classical theory of denial, to deny A is equivalent to asserting ¬A, that is A is correctly denied iff ¬A is correctly asserted. However, such classical equivalence has been nowadays disputed by many logical and philosophical approaches to assertion and denial. Aim of the workshop is to develop new modal, substructural and normative approaches to assertion and denial and to provide a fine-grained analysis of the logical constants and operators for these linguistic and epistemic acts. Moreover, we intend to develop new philosophical ideas on assertion and denial. In this vein innovative analyses for assertion and denial will be proposed.
