 The interest-relativity of causal explanation is thus crucial in Davidson’s grounding of the ineliminable explanatory role of mental properties within the framework of Anomalous Monism. If, as Anomalous Monism contends, mental event-types such as actions are not reducible to physical-event types, then the only way to explain actions (as opposed to mere bodily movements) so as to make them intelligible is by appeal to the mental properties of the cause—reasons. (For discussion of whether, in light of this, reason explanations can still be maintained to be causal explanations within the framework of Anomalous Monism, see the supplement on  Explanatory Epiphenomenalism.)
