 While differing in important ways, the various formulations of the argument, as well as the objections to them, exhibit a discernible pattern: proponents of mental anomalism highlight some feature of mental properties that is claimed to (1) sharply individuate them from physical properties and (2) create a conceptual tension with physical properties that precludes the possibility of strict lawful relations between these properties. According to the objections, however, the highlighted feature of mental properties either does not serve to distinguish it from physical properties or does not actually stand in any conceptual tension with physical properties that rules out lawlike relations. We will consider each interpretation, and its problems, in turn. In a later section  (5.3)  we will look at another objection related to the anomalism principle—that it is inconsistent with Davidson’s invocation of the doctrine that mental properties stand in a relation of supervenience to physical properties. For discussion of the relation between the anomalism principle and Davidson’s views about scheme-content dualism and semantic externalism, see the supplement on  Related Issues.
