Dynamic Propositionalism

Abstract

This chapter tackles the challenge of non-propositionalism. It argues that the source of the puzzle motivating non-propositionalism is the implicit assumption of the traditional, extra-linguistic account of context-sensitivity resolution. The problem is not in the idea that modal claims express truth-conditional content, but in the underlying assumption of how a context operates to determine this content. With a more nuanced understanding of the linguistic mechanisms driving context-sensitivity resolution, which captures the effects of discourse conventions, the apparent non-propositionality of modal discourse turns out to be an illusion. The account delivers ordinary propositional content even for discourses that prima facie evade propositionalist treatment. More importantly, a broader range of data suggests that such propositional content is required to properly account for the range of interpretations modal discourses allow. Thus, any adequate account has to take into account how discourse conventions identified in this chapter interact with the interpretation of modality.
