Abstract
Rowlands is concerned to explain and defend a doctrine about the relationship between mental states and physical states that he calls supervenience materialism. Very roughly speaking, this is the doctrine that it is the possession of physical properties by an object that makes for or determines the possession of mental properties by that object. In explaining this doctrine, Rowlands discusses various questions of interpretation, such as what should be meant by ‘determines’ and by ‘physical property’, and he also considers the implications of the doctrine for a family of questions about psychological laws and psychological explanations. In defending the doctrine, he does not attempt anything like a direct proof of its truth, but rather argues that it is to be preferred to other materialist doctrines that are studied in the literature.
