Linguistic pragmatics is defined as an approach to language from the point of view of the expression of 'beliefs' (in a very wide sense of the word). With the notion of 'belief' as a basic tool, a reinterpretation is offered for speech acts, implicature, semantic and pragmatic presupposition, and focus. Two striking claims: (i) there are only three basic speech acts, viz. statements, questions and commands; (ii) logic should be treated as part of linguistic pragmatics.
