 Given these concepts, a number of other concepts fall into place.  Dispositions  are reduced to counterfactual dependencies, though as is made clear in “Finkish Dispositions” (1997b), the reduction is not as simple as it might have seemed. Perception is reduced to dispositions and causes. (See, for instance, “Veridical Hallucination and Prosthetic Vision” (1980d).) We discussed the reduction of mental content to dispositions and causes in section 4. And we discussed the reduction of linguistic content to mental content in section 1. Values are reduced to mental states in “Dispositional Theories of Value” (1989b).
