Talking about action comes easily to us. We quickly make distinctions between voluntary and non-voluntary actions; we think we can tell what intentions are; we are confident about evaluating reasons offered in rational justification of action. Berent Enç provides a philosopher's sustained examination of these issues: he portrays action as belonging to the causal order of events in nature, a theory from which new and surprising accounts of intention and voluntary action emerge. Philosophers and cognitive scientists alike will find a provocative and enlightening read.
