Like many recent works in legal theory, especially those focusing on the apparently conflicting schools of legal positivism and natural law, Waluchow’s Inclusive Legal Positivism begins by admitting a degree of perplexity about the field; indeed, he suggests that the field has fallen into “chaos”. Disturbingly, those working within legal theory appear most uncertain about what the tasks of their field are. Legal philosophers often seem to suspect strongly that at least their colleagues in the field are confused about those (...) tasks. As a result, many recent books in legal theory are in large part exercises in legal metatheory, devoting many pages to attempts to define the purposes and goals of the field. Waluchow follows this trend and begins by expressing a desire to clarify the issues that separate those trying to give an account of the nature of law. His ultimate goal is to defend a version of legal positivism, inclusive legal positivism, that he thinks is at least implicit in H. L. A. Hart’s work. (shrink)

The paper deals with the possibility of a theory of the nature of law as such, a theory which will be necessarily true of all law. It explores the relations between explanations of concepts and of the things they are concepts of, the possibility that the law has essential properties, and the possibility that the law changes its nature over time, and that what is law at a given place and time depends on the culture and concepts of that place (...) and time. It also considers the possibility of understanding the institutions, such as the law, of cultures whose concepts are alien to us. The position advocated offers a reconciliation of ways in which a theory of the nature of law is parochial with its claim to be universal. (shrink)

A perennial question of jurisprudence has been whether there is a relationship between law and morality. Those who believe that there is no such relationship are known as while those who hold that some such relationship exists are usually tagged with the label Unfortunately, the latter phrase has been used in quite divergent senses. Sometimes it is used to designate any objectivist position about morality; as often, it labels the view that human nature determines what is objectively good or right; (...) and perhaps as often, it labels the view that some natural facts other than facts about human nature determine what is objectively good or right; and sometimes the label presupposes some divine origins to both morality and human law.

The natural law tradition in ethics and jurisprudence has undergone a revival in recent years, sparked by the work of John Finnis and the 'new natural law theorists' in the early 1980s. The ensuing decades have seen the emergence of an increasingly rich body of natural law scholarship, but this diversification has gone unnoticed by many outside the field. This article seeks to clarify the relationship between the core claims of the new natural law outlook and the more specific views (...) of individual authors. It begins by discussing the place of the new natural law theory within contemporary natural law scholarship. It then offers an account of the core elements of the new natural law framework that emphasises their compatibility with a range of ethical and philosophical viewpoints. (shrink)

Instead of being embarrassed and uneasy about the implications of the separation thesis, positivists should welcome the fact that they cannot account for the obligatoriness of law. The rule of recognition is only a social rule and introduces no grounds for obligation.

The argument of this article is that the dual-nature thesis is not only capable of solving the problem of legal positivism, but also addresses all fundamental questions of law. Examples are the relation between deliberative democracy and democracy qua decision-making procedure along the lines of the majority principle, the connection between human rights as moral rights and constitutional rights as positive rights, the relation between constitutional review qua ideal representation of the people and parliamentary legislation, the commitment of legal argumentation (...) to both authoritative and non-authoritative reasons, and the distinction between rules as expressing a real “ought” and principles as expressing its ideal counterpart. All of this underscores the point that the dual nature of law is the single most essential feature of law. (shrink)

The central argument of this article turns on the dual‐nature thesis. This thesis sets out the claim that law necessarily comprises both a real or factual dimension and an ideal or critical dimension. The dual‐nature thesis is incompatible with both exclusive legal positivism and inclusive legal positivism. It is also incompatible with variants of non‐positivism according to which legal validity is lost in all cases of moral defect or demerit (exclusive legal non‐positivism) or, alternatively, is affected in no way at (...) all by moral defects or demerits (super‐inclusive legal non‐positivism). The dual nature of law is expressed, on the one hand, by the Radbruch formula, which says that extreme injustice is not law, and, on the other, by the correctness argument, which says that law's claim to correctness necessarily includes a claim to moral correctness. Thus, what the law is depends not only on social facts, but also on what the law ought to be. (shrink)

Two claims lay the foundation for Beyleveld and Brownsword’s legal theory. The first says that immoral laws cannot be law, the second that rights to freedom and welfare can be proven to be logically necessary given merely the phenomenon of agency. The author argues that both claims are too strong. The first is an overidealization of law, which fails to do justice to its double nature as a real as well as an ideal phenomenon. The second must fail, for a (...) moral “ought” cannot be deduced from a merely instrumental “ought.”. (shrink)

The classical view of natural law, often traced to Aquinas' statement that "unjust law is no law at all," finds few defenders today. Even those most sympathetic to natural law theories do not embrace the classical account, but, instead, convert Aquinas' claim into a claim of political theory or construct new "natural law" accounts about the connection between legal and moral principles in a theory of adjudication. In this paper, I defend the view that extreme injustice disqualifies otherwise valid official (...) directives from counting as "law”. Indeed, I suggest that modern positivism's characterization of the normative claims that typify legal systems leads inevitably to the conclusion that "law," as a conceptual matter, must be understood by insiders who employ the term to admit moral limits on what can count as "law." I proceed as follows. First, I begin with some preliminary clarifying comments about methodology and the precise issue under discussion. Second, I describe four leading theories about the nature of law and consider how central ideas in each theory can be seen to generate opposing ideas that lead in turn to opposing models of law. Third, I state briefly the affirmative case for thinking that the classical natural law view is correct. Fourth, I identify basic mistakes in current approaches to the question about the nature of law that help explain why modern positivism has overlooked the manner in which it leads logically to the classical natural law view. Finally, I add some brief remarks about why it matters: what practical consequences follow from acknowledging that there are moral limits on what can count as law. (shrink)
