Abstract: On standard accounts, actions are caused by reasons (Davidson), and reasons are taken to be neural phenomena. Since neural phenomena are wholly understandable from a third-person perspective, standard views have no room for any ineliminable first-personal elements in an account of the causation of action. This article aims to show that first-person perspectives play essential roles in both human and nonhuman agency. Nonhuman agents have rudimentary first-person perspectives, whereas human agents—at least rational agents and moral agents—have robust first-person perspectives. The author concludes with a view of intentional causation, according to which reasons are constituted by (but not identical to) neural phenomena. The idea of constitution without identity allows for a causal account of action that automatically includes first-personal aspects of agency.
