Abstract
This book deals with central topics in the theory of action: the nature of action, ability and intention, the explanation of actions, and finally autonomy and responsibility. However, it is no mere simplified summary of the field for philosophical beginners. Rather, the summary is usually fairly sophisticated and always preparation for the presentation and defense of the author's own views. As such the book can be recommended not only as an excellent introduction to action theory, but also as an upper-level student's model of original analytic philosophy.
