Many of the most influential contributions to private law scholarship in the latter part of the twentieth century go beyond purely doctrinal accounts of private law. A distinctive feature of these analyses is that they straddle the divide between legal philosophy, on the one hand, and the sort of traditional doctrinal analysis applied by the courts, on the other. The essays contained in this collection continue in this tradition. The collection is divided into two parts. The essays contained in the first part consider the nature of, and justification for, private rights generally. The essays in the second part address the justification for particular private law rights and doctrines. Offering insightful and innovative analyses, this collection will appeal to scholars in all fields of private law and legal theory.
