 Davidson’s explicit considerations in favor of mental anomalism appeal to factors about the interpretation of action (linguistic as well as non-linguistic) and the ascription of mental states and events to persons. Several distinguishable features are noted—holism with respect to particular ascriptions, indeterminacy with respect to systematic interpretative frameworks, and the responsiveness of mental ascription to an ideal of rationality. According to holism, particular mental states can be cited in explanation of behavior only in the context of other mental states, which in turn depend upon others. Davidson claims that this dependency and holistic interrelatedness is “without limit” (Davidson 1970, 217). This echoes a related point he makes about the impossibility of definitional reduction of mental states in purely behavioristic terms, because of the ineliminable need for mental caveats (e.g., that the person understands, or notices or cares….) qualifying any attempt to state non-mental conditions for mental states.
