Russellian monism offers hope of a satisfying solution to both of these difficulties. Its elegant integration of consciousness in the material world looks to be a promising way of accounting for the causal role of human consciousness. If conscious states just are the intrinsic nature of brain states, then the causal action of brain states and the causal action of conscious states are arguably one and the same thing. And by postulating a phenomenal or protophenomenal nature to fundamental physical reality, Russellian monism hopes to provide an adequate account of the grounding of consciousness.[17]
