Abstract

In this thesis, I offer a study of a metaphysical theory that has acquired popularity in recent years: Dispositionalism. Dispositionalism is first and foremost an actualist, property-based theory of modality. The ontology of dispositionalism postulates, primus inter pares, that there are properties with a modal nature. Dispositionalists call these properties powers, mostly because of the role they play in doing what the argument says they should do: explaining natural modalities, i.e. first-order physical regularities. Albeit the view has increased in popularity in recent years, not much attention has been dedicated to investigating which theory of properties best fits the requirements from the metaphysics. The present thesis aims​ to remedy this.
