 The first explicitly powers-based account of determination is offered by Wilson (1999), as an application of a powers-based approach to the metaphysical dependence (a.k.a. ‘realization’) at issue in physicalism. She first motivates attention to powers (rather than supervenience or epistemic notions, in particular) as a properly metaphysical basis for characterizing realization; she then argues that a variety of seemingly diverse non-reductive physicalist accounts, including Yablo’s determinable-based account, are similar in aiming to ensure that the powers of a realized property are a proper subset of those of its realizing property (properties), in particular. Hence:
