Abstract

Quantifying-in is existential quantification into non-extensional contexts headed by a modal or attitudinal operator. The sense and sensibility of quantifying-in has often been challenged. This paper outlines a transparency-preserving semantics as a prerequisite for the logical validity of quantifying-in. The paper demonstrates how to formally validate quantifying into a non-factive, hyperintensional attitude context.
