 Hempel’s dilemma against the theory-conception is similar to an objection that one often hears propounded against the object-conception (cf. Jackson 1998). Consider a version of panpsychism according to which all the physical objects of our acquaintance are conscious beings just as we are. (For further discussion and different versions of this view, see  Panpsychism.)  Would physicalism be true in that situation? It seems intuitively not; however, if physicalism is defined via reference to the object-conception of a physical property then it is hard to see why not. After all, according to that conception, something is a physical property just in case it is required by a complete account of paradigmatic physical objects. But this makes no reference to the nature of paradigmatic physical objects, and so allows the possibility that physicalism is true in the imagined situation.
