 As we have seen above, Kim thinks that mental anomalism is susceptible of a kind of proof. This seems to be something stronger than Davidson himself claims (Davidson 1970, 215). In light of Davidson’s modesty about provability, and lack of explicit argumentation, some commentators (Child 1992; see also McDowell 1979) have suggested that mere reflection on the kinds of generalizations that we draw upon in coming to understand each other supports (but cannot prove) mental anomalism. Such generalizations are rules of thumb that hold only for the most part, and require, for their application to a given case, detailed contextual supplementation that cannot, by its nature, be included in anything like a universal generalization. The suggestion is that the sheer amount of contextual detail that would need to be accounted for in any statement with even a hope of being true is inappropriate for inclusion in strict lawful statements. A related strategy is to point to a lack of fixed, predetermined ends that all humans (or even any particular human over the course of her life) aim for in situations of choice, or values to maximize when deciding what to believe (such as simplicity, scope, and consistency in the case of theory choice) (Child 1992). The thought here is that if there are no such fixed ends or values, then no psychological generalization could be complete—since in particular contexts such ends or values play a crucial explanatory role in determining what to do or believe.
