The Idea of Private Law

Nearly twenty years after its original publication, The Idea of Private Law is widely recognized as a seminal contribution to legal philosophy, and one of the leading attempts to explain and justify the moral foundations of private law. Rejecting the functionalism popular among legal scholars, Ernest Weinrib advances the provocative idea that private law is an autonomous and non-instrumental moral practice, with its own structure and rationality. Weinrib draws on Kant and Aristotle to set out an approach to private law that repudiates the identification of law with politics or economics. Weinrib argues that private law is to be understood not as a mechanism for promoting efficiency but as a juridical enterprise in which coherent public reason elaborates the norms implicit in the parties' interaction. Private law, Weinrib tells us, embodies a special morality that links the doer and the sufferer of harm. Weinrib elucidates the standpoint internal to this morality, in opposition to functionalists, who view private law as an instrument in the service of external and independently justifiable goals. After establishing the inadequacy of functionalist approaches, Weinrib traces the implications of the formalism he proposes for our ideas of the structure, coherence, and normative grounding of private law. Furthermore, the author shows how this formalism manifests itself in the leading doctrines of private law liability. Finally, he describes the public but non-political role of the courts in articulating the special morality of private law. This revised edition makes accessible one of the major works of modern legal theory. It includes a new introduction by the author, looking back at the work, its origins, and its aspirations.
