 Critics of this extensionalist line of defense insisted that related questions remained about Anomalous Monism even taking into account the distinction between causation and explanation. In particular, they questioned whether mental properties could play any genuine explanatory role—whether they had explanatory relevance—given the priority assigned to physical properties in Davidson’s framework. Why think that mental properties explain anything given that the events which instantiate them always also instantiate physical properties that figure in causal laws? One thought here is that genuine explanations require laws, and mental anomalism, in ruling out psychological and psychophysical laws, cannot account for any explanatory role for mental properties vis a vis physical or mental events.
