Inquisitive Semantics and Indeterminacy

Abstract: An interesting recent product of the Amsterdam School in logic has been Inquisitive Semantics, a novel treatment of direct and indirect questions. I ask whether this theory can cast light on the difficult notion of indeterminacy. I contend that it can, but that some forms of indeterminacy require adjustments to the theory’s basic notions. I consider a range of putative instances of indeterminacy, from common-or-garden vagueness to quantum phenomena.
