It concentrates on well-established concepts such as presupposition, entailment, implicature, speech acts, subsentential speech acts, different cases of meaning as use, expressive meanings and expressive commitments, as well as the relation between knowledge and belief. The discussion goes beyond linguistic investigations and offers a wide philosophical perspective.
