Modals, Conditionals, and Imprecision

This paper proposes that the interpretation of modals is subject to (im)precision (a la Lasersohn 1999), explaining certain contextual domain shifting effects observed by Lewis (1979).

Bryan: This must be a pen – I’m looking right at it.
Alice: Not so; you could be the victim of a deceiving demon.

I argue that Alice raises the standard of precision in (1), thereby widening the domain of `have to’ to include otherwise ignorable worlds. This explains a number of similarities between domain shifting of the type in (1) and canonical cases of
imprecision, and simplifies the modal semantics. I will also extend the analysis to conditionals, accounting for so-called Sobel Sequences.
