 In what follows (2–5), each step of this argument will be analyzed and discussed separately, but always with an eye to the overall argument. In 6, a central objection to Anomalous Monism—that it appears unable to account for the causal/explanatory power of mental events and properties—will be explained and discussed. (For discussion of the relationship between Anomalous Monism and two other pillars of Davidson’s philosophy—his rejection of conceptual relativism and commitment to semantic externalism—see the supplement on  Related Issues.)
