Reductionists about agency maintain that an agent’s causing something is reducible to states and events involving the agent causing something. Some worry that reductionism cannot accommodate robust forms of agency, such as self-determination. One reductionist answer to this worry, which I call ‘identification reductionism,’ contends that self-governing agents are identified with certain attitudes, and so these attitudes’ causing a decision count as the agent’s self-determining the decision. I argue that a prominent species of identification reductionism developed by Harry Frankfurt, Agnieszka (...) Jaworska, Jeffrey Seidman, and David Shoemaker—according to which an agent is identified with his (deepest) cares—is inadequate. (shrink)
