Metaphysical Indeterminacy and Vague Existence

Abstract

This chapter examines whether the 'multiple actualities' account of metaphysical indeterminacy developed by Elizabeth Barnes and Robert Williams can allow for cases in which it is metaphysically indeterminate whether an object exists. Having focused on Theodore Sider's argument to the conclusion that indeterminacy in existence is incoherent, the multiple actualities framework is shown to offer a way of understanding indeterminate existence that undercuts Sider's argument.
