 Jaegwon Kim’s account of Davidson’s position (Kim 1985) attempts to do just this. Kim argues that if there were strict lawlike relations between mental and physical predicates, the ‘brute factness’ and contingency of the physical would ‘infect’ the mental. For instance, rationality considerations will typically lead us to attribute a belief that q to a person if we attribute a belief that p and also attribute a belief that p entails q. According to Kim’s account, beliefs involving very basic logical, semantic or conceptual relations like this hold of necessity—we cannot make sense of possible worlds where beliefs of the first two kinds are attributed but not the third.
