 This appears to ground the causal definition of anomic properties (whether mental or otherwise) in the fact that they answer to particular explanatory interests. This is contrasted with the case of ‘ultimate physical’ properties: “Explanation in terms of the ultimate physics, though it answers to various interests, is not interest relative” (Davidson 1987b, 45). This seems to collapse the distinction between psychology and all the other special sciences with respect to the question of anomalism. All of the latter answer to particular explanatory interests, and are thus selective with respect to the total sufficient condition for an effect-type (see Davidson 1987b, 45); the causal definition, and thus anomalism, of their vocabularies is owed to this interest-relativity and selectivity. ‘Ultimate physics’, on the other hand, “treats everything without exception as a cause of an event if it lies within physical reach (falls within the light cone leading to the effect)” (Davidson 1987b, 45).
