Abstract

Physicalism can be roughly characterised as the view that everything is physical, or that everything that is fundamental is physical, or that any non-physical entity—property, substance, fact, event, kind and what have you—is both dependent upon and fully determined by physical entities. Perhaps the greatest challenge facing physicalism is to explain how conscious experience can be accounted for within the physicalist framework. Given these rough characterisations of physicalism, before setting out to address the problem posed by consciousness, there is some prior conceptual work that must be done. In order for debates concerning the nature of consciousness and the ontology of mind and body to proceed in good order, something needs to be said about what it is for an entity to be a specifically physical entity. This paper offers reasons to think that, (i) at least given certain common metaphysical assumptions, discussions of what it is to be physical in general ought to be primarily concerned with what it is to be a physical property and that (ii) two popular approaches to characterising the physical - the Via Negativa and Object Physicalist approaches - face a serious problem.
