Abstract
Stalnaker's Context deploys the core machinery of common ground, possible worlds, and epistemic accessibility to mount a powerful case for the 'autonomy of pragmatics': the utility of theorizing about discourse function independently of specific linguistic mechanisms. Illocutionary force lies at the peripherybetween pragmatics-as the rational, non-conventional dynamics of context change-and semantics-as a conventional compositional mechanism for determining truth-conditional contents-in an interesting way. I argue that the conventionalization of illocutionary force, most notably in assertion, has important crosscontextual consequences that are not fully captured by a specification of dynamic effects on common ground. More generally, I suggest that Stalnaker's purely informational, propositional analysis of both semantic content and dynamic effects distorts our understanding of the function of language, especially of the real-world commitments and consequences engendered by robustly 'expressive' language like slurs, honorifics, and thick terms.
