In this revised edition, two distinguished philosophers have extended and strengthened the most authoritative text available on the philosophy of law and jurisprudence. While retaining their comprehensive coverage of classical and modern theory, Murphy and Coleman have added new discussions of the Critical Legal Studies movement and feminist jurisprudence, and they have strengthened their treatment of natural law theory, criminalization, and the law of torts. The chapter on law and economics remains the best short introduction to that difficult, controversial, and influential topic. Students will appreciate the careful organization and clear presentation of complicated issues as well as the emphasis on the relevance of both law and legal theory to contemporary society.
