Abstract

Could there be a power world? That is to say, could there be a world consisting of nothing but dispositional properties? If there couldn't be, then, obviously, the actual world is not such a world. That is one reason why answering this question is important. However, even if one thinks it is already obvious that the actual world is not a power world, answering this question is still important, because whether there could be a power world depends, in part, on whether all the properties in a world could be dispositional . It also depends on whether dispositional properties require nondispositional bases. Could water solubility, for example, be a brute feature of salt, or must this disposition be explicable in terms of some further, nondispositional property that salt also possesses? Answering these questions about the nature of properties is clearly essential to arriving at a plausible ontology of the actual world
