In recent years there has been a resurgence of interest in problems related to human agency and responsibility by philosophers and researchers in cognate disciplines. The present volume brings together original contributions by leading specialists working in this vital field of philosophical inquiry. The contents represent the state of the art of philosophical research on intentional agency, free will, and moral responsibility. The volume begins with chapters on the metaphysics of agency and moves to chapters examining various problems of luck. The final two sections have a normative focus, with the first of the two containing chapters examining issues related to responsible agency and blame and the chapters in the final section examine responsibility and relationships. This book will be of interest to researchers and students interested in both metaphysical and normative issues related to human agency.
