Abstract

Aim of this paper is to present and evaluate linguistic ersatzism, an actualist metaphysics of modality according to which possible worlds are maximal and consistent sets of sentences. In the first section, I make some general considerations about reductive theories of modality and the relation between modality and possible worlds, in the second I present a specific version of linguistic ersatzism and in the last section I present what I take to be the major problem for this kind of theories, namely that of finding a suitable surrogate for the possibilist’s notion of a merely possible object
