If one can understand what it is to be a free and rational agent, then one is some way to understanding what it is to be a conscious subject of experience. Although the book places the traditional Davidsonian agenda centre stage, it locates it historically by considering in particular Aristotle and Kant. It also takes the debate beyond Davidson by considering one of the most recent issues of interest in the philosophy of action, externalism. By focusing on the central issues of freedom and rationality as well as on the ontological structure of human action, Stout is able to offer readers a fresh and engaging treatment.
