The problem of intentionality in the pragmatics of communicative language use

The thesis is a metatheoretical analysis of the concept of ‘speaker’s intention’ as it is used in traditional linguistic-philosophical and in cognitive pragmatics. The analysis centers around works of Austin, Searle, Grice, and Relevance Theory. The main aim is to argue for the following thesis: (T1) if pragmatics is targeting on how speaker’s intentions contribute to linguistic choices in communicative language use, then focusing solely on causally efficient mental states and analyzing them at the utterance level necessarily leads to unsatisfactory consequences in theorizing. The secondary aim of the dissertation is to argue that: (T2) the traditional account of intentionality is tenable only if we take utterances as data. Surely, there are causally efficient intentions which lead the speaker to formulate her utterances as part of conversational turns. But speakers also have intentions which shape the conversation itself (motives, goals, plans). However: (T3) if we take discourses or conversations as divergent sources of data (besides of utterances), we run into an explanatory gap that cannot be filled mechanically: the structured-proposionalist theory is simply insufficient to grasp discourse-level intentions. To argue for (T3), I analyse speaker’s intentions in a fictive conversation (The smuggler sketch from Monty Python’s Flying Circus) through the “prisms” of Austin’s speech act theory, Searle’s (at least) two theories of intentions, Grice’s M-intention, and the ostensive-inferential view on communication.
