Linguistic Modality as Expressions of Social Power

The semantics of the linguistic modals is argued to be determined mainly by the power structure of the participants in the interaction. In the deontic uses of the modals, another determining factor is the expectations of the participants' attitudes towards the relevant action. By viewing the evidence as a power in its own right, our analysis can be generalized to the epistemic uses in a coherent way. The epistemic uses are seen as pragmatic strengthenings of the deontic uses, rather than as metaphorical mappings.
