This revised edition of The Idea of Private Law makes one of the major works of modern legal theory accessible to a new generation of lawyers and students. It includes a new introduction by the author, looking back at the work, its origins, and its aspirations.

The book combines philosophical exposition and legal analysis, and pays special attention to issues of tort law.

Private law governs our most pervasive relationships with other people: the wrongs we do to one another, the property we own and exclude from others' use, the contracts we make and break, and the benefits realized at another's expense that we cannot justly retain. The major rules of private law are well known, but how they are organized, explained, and justified is a matter of fierce debate by lawyers, economists, and philosophers.
