Abstract
This introductory chapter sets out the book’s scope and primary goals, and outlines some useful works on jurisprudence recommended by instructors in American law schools. It explains the central concerns of the subjects, distinguishing between descriptive legal theory, normative legal theory, and critical legal theory, and describes Lon Fuller’s entertaining hypothetical ‘Case of the Speluncean Explorers’, a popular launching pad for the comprehension of legal ideas. The important concept of the rule of law is discussed and analysed. There is an extended account of the controversial question of whether judicial review is undemocratic. The chapter concludes with an explanation of the point of legal theory.
