Wednesday, May 4th at 16:00 hrs we will have another session of our seminar: Michael De (Utrecht) will present his work entitled Logics for speech acts and propositional attitudes with the below abstract.
The meeting will take place in room D1.112 in Science Park 904.
Abstract
Rationality applies to a broad range of speech acts and propositional attitudes. The problem is that such acts and attitudes may not be rationally constrained by any of the usual notions of consequence-as-truth-preservation (for some given understanding of truth). I consider some other notions of consequence required in formulating rationality constraints on doubting and denial in particular in both classical and non-classical settings. A complete labelled natural deduction system is given for a logic of doubt which coincides with Strong Kleene logic.
