In this first U.S. edition of a classic work of comparative legal scholarship, Alan Watson argues that law fails to keep step with social change, even when that change is massive. To illustrate the ways in which law is dysfunctional, he draws on the two most innovative western systems, of Rome and England, to show that harmful rules continue for centuries. To make his case, he uses examples where, in the main, "the law benefits no recognizable group or class within the society (except possibly lawyers who benefit from confusion) and is generally inconvenient or positively harmful to society as a whole or to large or powerful groups within the society."

Widely respected for his "fearless challenge of the accepted or dominant view and his own encyclopedic knowledge of Roman law" (The Encyclopedia of Historians and Historical Writing), Watson considers the development of law in global terms and across the centuries. His arguments centering on how societies borrow from other legal systems and the continuity of legal systems are particularly instructive for those interested in legal development and the development of a common law for the European Union.
