This book offers an accessible and inclusive overview of the major debates in the philosophy of action. It covers the distinct approaches taken by Donald Davidson, G.E.M. Anscombe, and numerous others to answering questions like "what are intentional actions?" and "how do reasons explain actions?" Further topics include intention, practical knowledge, weakness and strength of will, self-governance, and collective agency. With introductions, conclusions, and annotated suggested reading lists for each of the ten chapters, it is an ideal introduction for advanced undergraduates as well as any philosopher seeking a primer on these issues.
