H. L. A Hart complained about the ambiguity of legal positivism, and proposed a definition that refers to particular explications of the concept of law, to certain theories of legal interpretation, to particular views on the moral problem of a duty to obey the law, and to a sceptical position with regard to the meta-ethical issue of the possibility of moral knowledge. It is said to be restricted to the Thesis of Separation — the contention that there is no necessary (...) connection between law and morals. In this chapter, the Separation Thesis is discussed even further, and has three shortcomings identified: first, that it has been vacillating between object-level contentions about moral qualities of the law; that the precise logical relation between both levels has never been properly accounted for; and that the question of necessary relations between morality and law hinges crucially on the presupposition that the very concept of law itself does not unravel into different sets of convenient stipulations from different epistemological angles, each of which renders the question of such necessary relations trivial. The Separation Thesis is also identified as having two versions: the Fallibility Law and the Neutrality Law. (shrink)

H. L. A. Hart is heir and torch-bearer of a great tradition in the philosophy of law which is realist and unromantic in outlook. It regards the existence and content of the law as a matter of social fact whose connection with moral or any other values is contingent and precarious. His analysis of the concept of law is part of the enterprise of demythologising the law, of instilling rational critical attitudes to it. Right from his inaugural lecture in Oxford (...) he was anxious to dispel the philosophical mist which he found in both legal culture and legal theory. In recent years he has shown time and again how much the rejection of the moralizing myths which accumulated around the law is central to his whole outlook. His essays on “Bentham and the Demystification of the Law” and on “The Nightmare and the Noble Dream” showed him to be consciously sharing the Benthamite sense of the excessive veneration in which the law is held in Common Law countries, and its deleterious moral consequences. His fear that in recent years legal theory has lurched back in that direction, and his view that a major part of its role is to lay the conceptual foundation for a cool and potentially critical assessment of the law are evident.
