Abstract
Montague, Prior, von Wright and others drew attention to resemblances between modal operators and quantifiers. In this paper we show that classical quantifiers can, in fact, be regarded as “S5-like” operators in a purely propositional modal logic. This logic is axiomatized and some interesting fragments of it are investigated.
