This second edition of the Oxford Handbook of Free Will is intended to be a sourcebook and guide to current work on free will and related subjects. Its focus is on writings of the past forty years, in which there has been a resurgence of interest in traditional issues about the freedom of the will in the light of new developments in the sciences, philosophy and humanistic studies. Special attention is given to research on free will of the first decade of the twenty-first century since the publication of the first edition of the Handbook. All the essays have been newly written or rewritten for this volume. In addition, there are new essayists and essays surveying topics that have become prominent in debates about free will in the past decade, including new work on the relation of free will to physics, the neurosciences, cognitive science, psychology and empirical philosophy, new versions of traditional views (compatibilist, incompatibilist, libertarian, etc.) and new views (e.g., revisionism) that have emerged. The twenty-eight essays by prominent international scholars and younger scholars cover a host of free will related issues, such as moral agency and responsibility, accountability and blameworthiness in ethics, autonomy, coercion and control in social theory, criminal liability, responsibility and punishment in legal theory, issues about the relation of mind to body, consciousness and the nature of action in philosophy of mind and the cognitive and neurosciences, questions about divine foreknowledge, providence and human freedom in philosophy of religion, and general metaphysical questions about necessity and possibility, determinism, time and chance, quantum reality, causation and explanation.
