This collection of contemporary essays by a group of well-known philosophers and legal theorists covers various topics in the philosophy of law, focusing on issues concerning liability in contract, tort and criminal law. The book is divided into four sections. The first provides a conceptual overview of the issues at stake in a philosophical discussion of liability and responsibility. The second, third and fourth sections present, in turn, more detailed explorations of the roles of notions of liability and responsibility in contracts, torts and punishment. The collection not only presents some of the most challenging work in legal philosophy, but it also demonstrates the interdisciplinary character of the field of philosophy of law, with contributors taking into account recent developments in economics, political science and rational choice theory. This thought-provoking volume will help to shed light on the underexplored ground that lies between law and morals.
