 The eight claims identified above do not correspond directly to these traditional questions in the philosophy of law. As already noted, claim (II) at least implicitly adopts a legal positivist understanding of law. Claim (VI) offers an explicit normative theory of adjudication, though one apparently at odds with how judges in fact decide cases. Central philosophic questions concerning the concept of law, its normativity, and the obligation to obey the law, however, are not directly addressed. The behavioral claim (IV) as well as the causal claim (V) and the explanatory claim (I), by contrast, concern empirical issues that philosophers of law generally neglect. Nevertheless, the controversy within the legal academy has generally regarded economic analysis of law as providing a comprehensive theory of law that challenges traditional approaches to law. Indeed, an explanation of the vehemence of the controversy should identify differences in fundamental views concerning law.
