Abstract

Most metaphysicians agree that powers can exist without being manifested. The main goal of this paper is to show that adherents of an unrestricted version of Dispositional Monism cannot provide a plausible metaphysical account of the difference between a situation in which a power-instance is not manifested and a situation in which a manifestation of that power-instance actually occurs unless they undermine their own view. To this end, two kinds of manifestation-relation are introduced and it is argued that dispositional monists should appeal to the former in order to offer the required account. After defending the introduction of token-level-manifestation-relations against objections to their metaphysical robustness and explanatory non-redundancy, it is finally argued that their existence is incompatible with the core tenet of an unrestricted form of Dispositional Monism because they cannot be powers.
