Exhaustivity in dynamic semantics; referential and descriptive pronouns

In this paper I argue that anaphoric pronouns should always be interpreted exhaustively. I propose that pronouns are either used referentially and refer to the speaker's referents of their antecedent indefinites, or descriptively and go proxy for the description recoverable from its antecedent clause. I show how this view can be implemented within a dynamic semantics, and how it can account for various examples that seemed to be problematic for the view that for all unbound pronouns there always should be a notion of exhaustivity/uniqueness involved. The uniqueness assumption for the use of singular pronouns is also shown to be importantto explain what the discourse referents used in dynamic semantics represent.
