In this article, we propose a novel account of general jurisprudence by situating it within the broader project of metanormative inquiry. We begin by showing how general jurisprudence is parallel to another well-known part of that project, namely, metaethics. We then argue that these projects all center on the same task: explaining how a certain part of thought, talk, and reality fits into reality overall. Metalegal inquiry aims to explain how legal thought, talk, and reality fit into reality. General jurisprudence (...) is the part of metalegal inquiry that focuses on universal legal thought, talk, and reality. (shrink)

One of the first volumes in the new series of prestigious Oxford Handbooks, The Oxford Handbook of Jurisprudence and Philosophy of Law brings together specially commissioned essays by twenty-six of the foremost legal theorists currently writing, to provide a state of the art overview of jurisprudential scholarship.

For the past four decades, Anglo-American legal philosophy has been preoccupied – some might say obsessed – with something called the “Hart-Dworkin” debate. Since the appearance in 1967 of “The Model of Rules I,” Ronald Dworkin’s seminal critique of H.L.A. Hart’s theory of legal positivism, countless books and articles have been written either defending Hart against Dworkin’s objections or defending Dworkin against Hart’s defenders. My purpose in this essay is not to declare an ultimate victor; rather it is to identify (...) precisely the core issue around which the debate is organized. Is the Hart-Dworkin debate, for example, about whether the law contains principles, as well as rules? Or does it concern whether judges have discretion in hard cases? Is it about the proper way to interpret legal texts in the American legal system? Or is it about the very possibility of conceptual jurisprudence? Although trying to capture the essence of a philosophical debate can be tricky, I think that there is an important unity to the Hart-Dworkin debate that can be described in a relatively straightforward manner. I suggest that the debate is organized around one of the most profound issues in the philosophy of law, namely, the relation between legality and morality. Dworkin’s basic strategy throughout the course of the debate has been to argue that, in one form or another, legality is ultimately determined not by social facts alone, but by moral facts as well. This contention directly challenges, and threatens to undermine, the positivist picture about the nature of law, in which legality is never determined by morality, but solely by social practice. As one might expect, the response by Hart and his followers has been to argue that this dependence of legality on morality is either merely apparent or does not, in fact, undermine the social foundations of law. The Hart-Dworkin debate, I also try to show, is not a monolithic entity. In the second half of the paper, I describe how Dworkin modified his critique to circumvent the responses of Hart’s followers, thereby inaugurating a new phase in the debate. Virtually no attention, however, has been paid to this latter challenge, which is especially surprising given that none of the previous positivistic defenses are helpful against it. I then sketch out a possible response positivists might offer to this extremely powerful objection. (shrink)

Though the “internal point of view” is perhaps H.L.A. Hart’s greatestcontribution to legal theory, this concept is also often and easily misunderstood. This is unfortunate, not only because these misreadings distort Hart’s theory, but, more importantly, because they prevent us from appreciating the infirmities of sanction-centered theories of law and the compelling reasons why they ought to be rejected. In this paper, I try to address some of these confusions. What, exactly, is the internal point of view? What role (or (...) roles) does it play in Hart’s theory? And how does an adequate appreciation for the centrality of the internal point of view lead to the rejection of sanction-centered theories? (shrink)

Lays out basics of planning theory of law. Roughly, characterizes the internal point of view as a complex planning intention rather than a response to a recurring coordination problem. We are not responding to such a problem per se, but rather to a cooperation problem - and thus the structure of the attitude or intention must be different. It is officials who have the relevant attitude. Does not reject conventionalism, but argues that the convention is of a different sort than (...) is typically thought. Considers the basic commitment of legal positivism to be a commitment law as social fact. (shrink)

It is hard to think of a more banal statement one could make about the law than to say that it necessarily claims legal authority to govern conduct. What, after all, is a legal institution if not an entity that purports to have the legal power to create rules, confer rights, and impose obligations? Whether legal institutions necessarily claim the moral authority to exercise their legal powers is another question entirely. Some legal theorists have thought that they do—others have not (...) been so sure. But no one has ever denied that the law holds itself out as having the legal authority to tell us what we may or may not do. (shrink)

One of the principal lessons of The Concept of Law is that legal systems are not only comprised of rules, but founded on them as well. As Hart painstakingly showed, we cannot account for the way in which we talk and think about the law - that is, as an institution which persists over time despite turnover of officials, imposes duties and confers powers, enjoys supremacy over other kinds of practices, resolves doubts and disagreements about what is to be done (...) in a community and so on - without supposing that it is at bottom regulated by what he called the secondary rules of recognition, change and adjudication. Given this incontrovertible demonstration that every legal system must contain rules constituting its foundation, it might seem puzzling that many philosophers have contested Hart's view. In particular, they have objected to his claim that every legal system contains a rule of recognition. More surprisingly, these critiques span different jurisprudential schools. Positivists such as Joseph Raz, as well as natural lawyers such as Ronald Dworkin and John Finnis, have been among Hart's most vocal critics. In this essay, I would like to examine the opposition to the rule of recognition. What is objectionable about Hart's doctrine? Why deny that every legal system necessarily contains a rule setting out the criteria of legal validity? And are these objections convincing? Does the rule of recognition actually exist? This essay has five parts. In Part One, I try to state Hart's doctrine of the rule of recognition with some precision. As we will see, this task is not simple, insofar as Hart's position on this crucial topic is often frustratingly unclear. I also explore in this part whether the United States Constitution, or any of its provisions, can be considered the Hartian rule of recognition for the United States legal system. In Part Two, I attempt to detail the many roles that the rule of recognition plays within Hart's theory of law. In addition to the function that Hart explicitly assigned to it, namely, the resolution of normative uncertainty within a community, I argue that the rule of recognition, and the secondary rules more generally, also account for the law's dexterity, efficiency, normativity, continuity, persistence, supremacy, independence, identity, validity, content and existence. In Part Three, I examine three important challenges to Hart's doctrine of the rule of recognition. They are: 1) Hart's rule of recognition is under- and over-inclusive; 2) Hart cannot explain how social practices are capable of generating rules that confer powers and impose duties and hence cannot account for the normativity of law; 3) Hart cannot explain how disagreements about the criteria of legal validity that occur within actual legal systems, such as in American law, are possible. In Parts Four and Five, I address these various objections. I argue that although Hart's particular account of the rule of recognition is flawed and should be rejected, a related notion can be fashioned and should be substituted in its place. The idea, roughly, is to treat the rule of recognition as a shared plan which sets out the constitutional order of a legal system. As I try to show, understanding the rule of recognition in this new way allows the legal positivist to overcome the challenges lodged against Hart's version while still retaining the power of the original idea.

Legal positivism is generally characterized by its commitment to two theses Separability Thesis,” denies any necessary connection between morality and legality. Legal positivists do not require that a norm possess any desirable, or lack any undesirable, moral attributes in order to count as law.

In this paper, I present a new argument against inclusive legal positivism. As I show, any theory which permits morality to be a condition on legality cannot account for a core feature of legal activity, namely, that it is an activity of social planning. If the aim of a legal institution is to guide the conduct of the community through plans, it would be self-defeating if the existence of these plans could only be determined through deliberation on the merits. I (...) also argue that, insofar as inclusive legal positivism was developed as a response to Ronald Dworkin's critique of H. L. A. Hart's theory of law, it was founded on a mistake. For once we appreciate the role that planning plays in legal regulation, we will see that Dworkin's objection is based on a flawed conception of legal obligations and rights and hence does not present an objection that inclusive legal positivists were required to answer.

The paradox of the Unexpected Hanging, related prediction paradoxes, and the Sorites paradoxes all involve reasoning about ordered collections of entities: days ordered by date in the case of the Unexpected Hanging; men ordered by the number of hairs on their heads the case of the bald man version of the Sorites. The reasoning then assigns each entity a value that depends on the previously assigned value of one of the neighboring entities. The final result is paradoxical because it conflicts (...) with the obviously correct, commonsensical value. The paradox is due to the serial procedure of assigning a value based on the newly assigned value of the neighbor. An alternative procedure is to assign each value based only on the original values of neighbors - a parallel procedure. That procedure does not give paradoxical answers. (shrink)

Preview: /Scott Shapiro interviewed by Eli Kramer / EK: Thanks for talking with me today. Your book, The Internationalists: How a Radical Plan to Outlaw War Remade the World is not only kind of groundbreaking in the way it changes how we think about the role of international law in the history and philosophy of culture, and some of our progressive success of not having disastrous violence shape us each generation, but it has only become more relevant since the war (...) in Ukraine was launched. As a starting point for our conversation, can you summarize the main premise of the work? SS: It’s a story about the modern international order. Despite its imperfections, it needs to be defended now more than ever. The central argument of the book is that the origins of the modern international order can be traced to a specific date in history. Namely August 27th, 1928, when the great leaders of the world gathered in Paris to outlaw war. The treaty that was signed on that day is sometimes called the Kellogg-Briand Pact, the Peace Pact, or the Paris Peace Pact. Its actual formal designation was “The General Treaty for the Renunciation of War,” basically saying it all was an attempt to outlaw war. Now, of course most people have never heard of it. It’s amazing that basically all the countries in the world decide to outlaw war, which in itself is initially a strange thing to do, but then nobody knows about it. (shrink)

Irrational people create problems not only for themselves and those around them, but also for those who study them. They cause trouble for social scientists because their actions are inexplicable, at least according to generally accepted models of explanation. Explanations in the social sciences normally assume the form of rationalizations: actions are explained by showing that, relative to what the subjects believe and desire, the actions were done for good reasons. Conversely, when good reasons cannot be found for why someone (...) acted as they did, their behavior remains inscrutable. Irrational people, therefore, stymie social scientists because their actions do not reveal the rationality needed to produce adequate explanations. (shrink)
