The recent outbreak of Ebola in West Africa has killed thousands of people, including healthcare workers. African responses have been varied and largely ineffective. The WHO and the international community’s belated responses have yet to quell the epidemic. The crisis is characteristic of a failure to properly comply with the International Health Regulations 2005. More generally, it stems from a failure of international health justice as articulated by a range of legal institutions and instruments, and it should prompt us to (...) question the state and direction of approaches to the governance of global public health. This paper queries what might be done to lift global public health as a policy arena to the place of prominence that it deserves. It argues that there are at least two critical reasons for the past, present and easily anticipated future failings of the global public health regime. After exploring those, it then articulates a new way forward, identifying three courses of action that might be adopted in realising better health outcomes and global health justice, namely value, institutional and legal reform.

Equal freedom is the common starting point for most contractual theories of justice from Hobbes and Rousseau to Rawls. But while equal freedom defines a common starting point for these theories, this does not result in a general consensus on the conception of justice. On the contrary, different ways of conceptualizing the contractual starting point leads to different conceptions of the demands of justice. To fully understand the relationship between equal freedom and justice we therefore first need to explicate how (...) and why the initial condition of equality is transformed into demands of justice. In this paper we discuss how this transformation takes place in the theories of Hobbes, Rousseau and Rawls, with particular emphasis on the vexed relationship between motivation and justification.

One of Han Fei’s most trenchant criticisms against the early Confucian political tradition is that, insofar as its decision-making process revolves around the ruler, rather than a codified set of laws, this process is the arbitrary rule of a single individual. Han Fei argues that there will be disastrous results due to ad hoc decision-making, relationship-based decision-making, and decision-making based on prior moral commitments. I lay out Han Fei’s arguments while demonstrating how Xunzi can successfully counter them. In doing so, (...) I argue that Xunzi lays out a political theory restricting the actions of the ruler through both the use of ritual and law, which allows him to develop a theory that legitimizes government while at the same time constraining itself. Xunzi’s political theory makes important strides in its attempt to recognize the importance of the ruler as a moral exemplar while also restricting his control in the political process. (shrink)

An influential strand in recent action-theory employs constitutivist arguments in order to present accounts of individual agency and practical identity. I argue for an extension of this framework into the interpersonal realm, and suggest using it to reassess issues in jurisprudence. A legal system is an instantiation of the solution to the inescapable tasks of self-constituting action and identity-formation in the presence of other agents. Law's validity and normativity can be enlightened when the constitutivist approach considers the external prerequisites of (...) individuals' self-conceptions qua agents. More specifically, this argumentative strategy allows a reassessment of Fuller's “internal morality of law.” Whereas, pace Fuller, morally substantive conclusions cannot be derived from formal criteria of legality, there are unconditional normative requirements that constrain law.

In this inaugural lecture, delivered at the University of Birmingham in January 2014, I sketch the outline of a theory of moral education. The theory is an attempt to resolve the tension between two thoughts widely entertained by teachers, policy-makers and the general public. The first thought is that morality must be learned: children must come to see what morality requires of them and acquire the motivation to submit to its authority. The second thought is that morality is controversial: there (...) is deep uncertainty about both the requirements of morality and the reasons to comply with them. I draw distinctions between two kinds of moral education and between two kinds of moral inquiry . I argue that some basic moral standards are robustly justified and that schools should promote subscription to these standards by means of both moral formation and directive moral inquiry. (shrink)

Matthew Clayton, David Stevens and Laura D’Olimpio have advanced a series of objections to arguments I set out in my recent book A Theory of Moral Education – in particular to the problem-of-sociality justification for basic moral standards. Here I reply to their objections.

A representation methodology for knowledge allowing multiple interpretations is described. It is based on the following conception of legal knowledge and its open texture. Since indeterminate, legal knowledge must be adapted to fit the circumstances of the cases to which it is applied. Whether a certain adaptation is lawful or not is measured by metaknowledge. But as this too is indeterminate, its adaptation to the case must be measured by metametaknowledge, etc. This hierarchical model of law is quite well-established and (...) may serve well as a basis for a legal knowledge system. To account for the indeterminacy of law such a system should support the construction of different arguments for and against various interpretations of legal sources. However, automatizing this reasoning fully is unsound since it would imply a restriction to arguments defending interpretations anticipated at programming time. Therefore, the system must be interactive and the user''s knowledge be furnished in a principled way. Contrary to the widespread opinion that classical logic is inadequate for representing open-textured knowledge, the framework outlined herein is given a formalization in first order logic. (shrink)

. Can the label “law” apply to rules as amoral as the enactments of the Nazis? This question confronted the courts in Germany after 1945. In dealing with it, the judges had to take sides in the philosophical debate over the concept of law. In this context, the prominent voices of the legal philosophers Gustav Radbruch and Hans Kelsen could not go unheard. This paper draws on what could have been the “Radbruch‐Kelsen debate on Nazi Law.” In examining the debate, (...) it will argue for a substantive account of the morality of the law, as expressed in Radbruch's Formula.

Much work on legal knowledge systems treats legal reasoning as arguments that lead from a description of the law and the facts of a case, to the legal conclusion for the case. The reasoning steps of the inference engine parallel the logical steps by means of which the legal conclusion is derived from the factual and legal premises. In short, the relation between the input and the output of a legal inference engine is a logical one. The truth of the (...) conclusion only depends on the premises, and is independent of the argument that leads to the conclusion.This paper opposes the logical approach, and defends a procedural approach to legal reasoning. Legal conclusions are not true or false independent of the reasoning process that ended in these conclusions. In critical cases this reasoning process consists of an adversarial procedure in which several parties are involved. The course of the argument determines whether the conclusion is true or false. The phenomenon of hard cases is used to demonstrate this essential procedural nature of legal reasoning. (shrink)

This paper describes a model of legal reasoning and a logic for reasoning with rules, principles and goals that is especially suited to this model of legal reasoning. The paper consists of three parts. The first part describes a model of legal reasoning based on a two-layered view of the law. The first layer consists of principles and goals that express fundamental ideas of a legal system. The second layer contains legal rules which in a sense summarise the outcome of (...) the interaction of the principles and goals for a number of case types. Both principles, goals and rules can be used in legal arguments, but their logical roles are different. One characteristic of the model of legal reasoning described in the first part of the paper is that it takes these logical differences into account. Another characteristic is that it pays serious attention to the phenomena of reasoning about the validity and acceptance of rules, respectively principles and goals, and about the application of legal rules, and the implications of these arguments for the use of rules, principles and goals in deriving legal conclusions for concrete cases.The second part of the paper first describes a logic (Reason-Based Logic) that is especially suited to deal with legal arguments as described in terms of the previously discussed model. The facilities of the logic are illustrated by means of examples that correspond to the several aspects of the model. (shrink)

This paper aims at providing an account of juridical acts that forms a suitable starting point for the creation of computational systems that deal with juridical acts. The paper is divided into two parts. Because juridical acts will be analyzed as intentional changes in the world of law, the ‘furniture’ of this world, that consists broadly speaking of entities, facts and rules, plays a central role in the analysis. This first part of the paper deals with this furniture and its (...) philosophical underpinnings, and at the same time introduces most of the logical apparatus that will be used to deal with it. The focus in the first part is on static and dynamic legal rules and their interplay in constituting the world of law. (shrink)

After a brief sketch of the history of philosophical pragmatism generally, and of legal pragmatism specifically (section 1), this paper develops a new, neo-classical legal pragmatism: a theory of law drawing in part on Holmes, but also on ideas from the classical pragmatist tradition in philosophy. Main themes are the "pluralistic universe" of law (section 2); the evolution of legal systems (section 3); the place of logic in the law (section 4); and the relation of law and morality (section 5).

Abstract.According to the normative theory of legal science, juristic ought‐sentences describe rules, since legal science just deals with rules, and rules cannot be described but by means of ought‐sentences. The author challenges this view. Two different constructions of “describing rules” are proposed: Namely, either interpreting or stating the validity of rules. “Interpreting rules,” in its turn, can be understood in three different senses: listing all the possible meanings of rule‐formulations, reporting the different interpretations a rule‐formulation has in fact received by (...) courts, or ascribing meaning to rule‐formulations. However, the author argues that ought‐sentences are not the proper tools to accomplish such tasks. At the same time, juristic ought‐sentences cannot be understood as validity statements, since they neither mention any rule whatsoever, nor include the term “valid.” Further, if validity‐statements were ought‐sentences, their logical behaviour would reflect the logic of rules themselves. However, as the late Kelsen argued, things do not run this way, since two inconsistent ought‐sentences, if understood as validity statements, can paradoxically both be true, as well as both false. Hence, validity‐statements cannot be reduced to ought‐sentences iterating the rules which they (are supposed to) refer to. (shrink)

According to the common thinking of continental European lawyers, a rule is invalid each and every time either it was not produced in accordance with the metarules which govern the production of rules in the system, or it is inconsistent with a “superior” (higher‐ranked) rule belonging to the same system. Thus, a better understanding of the concept of invalidity demands a careful inquiry into the various kinds of meta‐rules which govern the production of rules as well as into the various (...) kinds of normative hierarchies. The paper is mainly devoted to such an analysis. Five different grounds for invalidity are distinguished. The analysis further shows that invalidity can affect rules as well as legal provisions and legal sources. Further, invalidity should be sharply distinguished from non‐existence (existence being a sufficient condition for rules to be applied). In most legal systems, invalid rules too are susceptible of judicial application: At least, until their invalidity is “declared” (in a constitutive way) by a competent organ (namely, a constitutional court, as far as statutory rules are concerned).

The author discusses a number of issues in the theory of legal sources. The first topic is whether sources should be conceived of as acts or texts. The alternatives are connected with two competing theories of legal interpretation (viz., the cognitive theory and the sceptical theory), which entail different concepts of legal rules and law‐making. The second topic is whether a “formal” or a “material” criterion of recognition of sources should be preferred. The third section is devoted to the analysis (...) of rules of change. Four theories of rules of change are discussed, and five kinds of such rules are distinguished. The fourth section concerns judicial law‐making, with special reference to the creation of new legal rules by constitutional courts. (shrink)

Several critics have denied value incommensurability – or the claim, roughly, that there is no common measure in terms of which values can be weighed – on the basis of what we might call the argument from easy cases. Although the argument from easy cases is quite popular, what is much less often discussed is what exactly the argument entails – in other words, what sort of further commitments the argument generates. Suppose we grant that easy cases point to the (...) existence of a common measure. How then should we think about this common measure? What is its scope? How widely does it range? I attempt to clarify these questions and in the process evaluate the force of the argument from easy cases. (shrink)

Anglo-American theories of criminal responsibility require scholars to grapple with, inter alia, the relationship between the formal rule of law and the powers of the lay jury as well as two inherent ideas of freedom: freedom of the will and political liberty. Here, by way of canvassing my past work and prefiguring future work, I sketch some elements of the history of the Anglo-American jury and offer some glimpses of commentary on the interplay between the jury—particularly its application of conventional (...) morality to criminal judgments—and the formal rule of law of the state. My central intent is to pose questions for further study regarding the historical behavior of the jury, the jury’s role in reinforcing notions of political liberty and free will, and, primarily, how scholarly conceptions of the jury’s role and behavior have informed elite theory regarding the justifications for imposing criminal responsibility.

This paper centers upon the issue, within the project of analytic jurisprudence, of how to construe the status of the legal activities of a state when there is a disjuncture between a nation's formal legal commitments, such as those stated within a bill or charter of rights, and the way in which its officials actually engage in the practice of law, i.e., legislation and adjudication. Although there are two positions within contemporary legal theory which focus directly on this issue (Inclusive (...) and Exclusive Legal Positivism), neither is able to offer an acceptable descriptive-explanatory account of the variety of legal activities at play within such situations. Thus, tensions between legal formality and practice, existent in many legal systems today, can be used to delineate a theoretical gap in regard to our understanding of law. This paper serves to acknowledge that point, and suggests a possible constructive solution to the positivists' descriptive-explanatory problem. Furthermore, in taking seriously the gap between the normative orientation of a legal system and its de facto practice, this paper also suggests other areas within analytic jurisprudence that might be meaningfully informed by that issue.

This essay explores the implications of H.L.A. Hart's rule of recognition for identifying ultimate standards of law in the United States. The effort reveals that these standards are much more complex than is commonly supposed. Not all of the federal constitution is part of the “ultimate” rule of recognition, and much else must be included in that rule. The analysis uncovers many possibilities for how ultimate standards relate to derivative standards that are omitted or barely hinted at in Hart's account. (...) Some of these possibilities pose genuine difficulty for Hart's basic theory and help illuminate the relation of conventional and normative elements in an adequate account of law, a subject addressed in the final section of the essay.

There is a thesis that legal rules need to be made public because people cannot guide their conduct by rules they cannot know. This thesis has been a mainstay of anti-positivism and the controversy over it continues apace. However, positivism can accommodate the secret laws thesis. The deeper import of the debate over secret laws concerns our understanding of law's nature. In this regard secrecy merits attention as a candidate necessary connection between law and immorality. In addition the mediating role (...) of lawyers as experts in ascertaining the law should be highlighted. It has been widely overlooked despite the fact that lawyers are criterial in Hart's concept of law. (shrink)

ABSTRACTDespite a resurgence of interest in character education, just what ‘character’ means is contested. Two strands, while overlapping, diverge on several questions: Is character centrally about moral qualities or more inclusive? Does it consist of one or multiple traits? Does it regard virtue as independently or instrumentally good? Is character a set of dispositions or behaviors? Is it a matter of reflection and reason or habits and skills? Those aligned with the first part of each dichotomy I label purists, the (...) second reformists. In Parts I and II the two perspectives are detailed. While some advocate merging the two camps, as reviewed in Part III, I objection to this proposal. Such a marriage blurs key distinctions and obscures the centrality of morality to character. It also questionably enlarges the role of schools. The conclusion reached is that the role of schools in teaching character is limited. (shrink)

Ronald Dworkin states in his preface to “Law's Empire” that he is doing a phenomenology of law. In regards to a phenomenology of law, I wish to investigate Dworkin's theory of law, and subsequently, what is left out in order for it to be considered a phenomenological account. In doing so, I will compare Dworkin's phenomenology of law to Schütz's phenomenology of the social world. The comparison between the two will illuminate what I believe is necessary for law, and that (...) is a Phenomenology of the Pre‐Legal. (shrink)

I will center the discussion of the Hart-Fuller debate on the five claims Hart mentions might be understood as legal positivisms main tenets: (1) the command theory; (2) the no necessary connection thesis; (3) the methodological claim; (4) the charge of positivism as formalism and the problem of interpretation; and (5) the meta-ethical confusion. In light of these five claims, I will explore whether the exchange of views between Hart and Fuller in 1957 truly amounted to a debate. Sorting out (...) this issue is the aim of this article.

The debate on political constitutionalism has entirely neglected the constitution-making dimension. This is probably due to the fact that constitution-making usually brings with it undesirable outcomes such as the entrenchment of rights or structures. These outcomes do not respect reasonable disagreement among citizens because they violate the only fair system for settling disagreement: majority rule and equal voting rights. This article argues that political constitutionalists may regret the absence of any claim about constitution-making. Either they are overlooking certain problems inherent (...) to the electoral process that is supposed to tackle disagreement or, even worse, they are downplaying the entrenching effect of ordinary political processes by ignoring the redemptive properties of constituent power. In both cases, their claims undermine the political dimension of constitutionalism. (shrink)

While defeasibility in legal reasoning has been the subject of recent scholarship, it has yet to be studied in the context of judicial opinion. Yet, being subject to appeal, judicial decisions can default for a variety of reasons. Prakken (2001) argued that the defeasibility affecting reasoning involved in adversarial legal argumentation is best analysed as procedural rather than logical. In this paper we argue that the defeasibility of ratio decendi is similarly best explained and modeled in a procedural and dialectical (...) framework. We propose that appeals are best understood as meta-dialogues about the reasoned dialogue occurring in the initial trial. (shrink)

This article examines the possibility of moral considerations and arguments serving as validity conditions of law in legal positivist theory. I argue that, despite recent attempts, this possibility has yet to be established. My argument turns on a defense of Joseph Raz's Sources Thesis, yet I do not adopt his famous “argument from authority.” Rather, I offer a renewed defense of the distinction between creation and application of law and argue that moral considerations and arguments, whether recognized in law or (...) not, remain arguments about the modification of law.

This article will compare and contrast two very different accounts of convention: the game-theoretical account of Lewis in Convention, and the account initially proposed by Margaret Gilbert (the present author) in chapter six of On Social Facts, and further elaborated here. Gilbert’s account is not a variant of Lewis’s. It was arrived at in part as the result of a detailed critique of Lewis’s account in relation to a central everyday concept of a social convention. An account of convention need (...) not be judged by that standard. Perhaps it reveals the nature of an important phenomenon. Looked at in that light, these very different accounts are not incompatible. Indeed, neither should be ignored if one is seeking to understand the way in which human beings arrive at some degree of social order. (shrink)

This paper reviews some of the growing body of work in the analytic philosophy of social phenomena, with special reference to the question whether adequate accounts of particular social phenomena can be given in terms that are individualistic in a sense that is specified. The discussion focusses on accounts of what have come to be known as shared intention and action. There is also some consideration of accounts of social convention and collective belief. Particular attention is paid to the need (...) to explain the association of certain rights and obligations with the phenomena at issue. (shrink)

This paper introduces the author's approach to everyday ascriptions of collective cognitive states as in such statements as we believe he is lying. Collective epistemology deals with these ascriptions attempting to understand them and the phenomena in question.

This article invokes the idea of a wise society, something that has received little attention from contemporary philosophers. It argues that, given plausible interpretations of the relevant terms, the wiser a society is, the less free it is. Even if one prefers a different account of a wise society, the argument in question is significant, for on this account a wise society possesses features that would seem to be desirable whatever their relationship to wisdom in particular: it makes many true (...) value judgments. What is it for a society to make a true value judgment? An account is offered, and it is argued that all else being equal, a society that increases its stock of true value judgments so understood becomes less free. A number of questions that this argument may prompt are discussed. (shrink)

Batman is allied with modern natural law in the way he relies upon reason to bring about his vision of ‘true justice’, operating as a force external to law. This vision of justice is a protective one, with Batman existing as a guardian—a force for resistance against the corruption of the state and the failures of the legal system. But alongside his rational means, Batman also employs violence as he moves beyond the boundaries of the civilised state into the dark (...) and violent world outside law’s protection. He thus sacrifices his own safety to ensure the safety of others—he is a Dark Knight, a sentinel, fighting the nasty and brutish underworld of criminality in his effort to bring rational order to the world and protect the people of Gotham from criminal harm. This fight for justice is fuelled by a deeply private trauma: the murder of Bruce Wayne’s parents: a private desire for vengeance that Batman transcends. In navigating Batman’s jurisprudential dimensions, we are ultimately reminded that private desires and motivations are enfolded within the public structures of justice. (shrink)

Imagine a citizen (call her Ellen) engages in conduct the state says is a crime, for example, money laundering. Imagine too that the state of which Ellen is a citizen has decided to make money laundering a crime. Does the state wrong Ellen when it punishes her for money laundering? It depends on what you think about the authority of the criminal law. Most criminal law scholars would probably say that the criminal law as such has no authority. Whatever authority (...) is has depends on how well it adheres to the demands of morality inasmuch as morality is the only authority we have. Thus if morality says that money laundering should not be a crime then the state wrongs Ellen when it punishes her. But if the criminal law as such does have authority, and if in the exercise of its authority the state has decided to make money laundering a crime, then the state does Ellen no wrong when it punishes her.

In this paper I outline various different objects of investigation that may be picked out by word “law” (or its cognates). All of these objects must be investigated in an integrated way before one can provide a complete philosophical explanation of the nature of law. I begin with the distinction between laws (artefacts) and law (the genre to which the artefacts belong). This leads me to the distinction between the law (of a particular legal system) and law (the genre of (...) artefacts). Then I discuss the contrast between law (the genre of artefacts) and law (the practice). Finally I comment on legality as the name of an ideal for laws and legal systems to live up to. I commend H. L. A. Hart's explanation of the nature of law for investigating these various objects in an integraed way, while nevertheless respecting the distinctions among them. I also criticise some of R. M. Dworkin's work for failing to respect the same distinctions. (shrink)

Despite great advances in recent scholarship on the political philosophy of John Rawls, Rawls’s conception of stability is not fully appreciated. This essay aims to remedy this by articulating a more complete understanding of stability and its role in Rawls’s theory of justice. I argue that even in A Theory of Justice Rawls maintains that within liberal democratic constitutionalism judgments of relative stability typically adjudicate decisively among conceptions of justice and is committed to more deeply than to the substantive content (...) of justice as fairness. This essay thus emphasizes the continuity of Rawls’s thought over time and motivates the position that Rawlsian stability is as philosophically significant and distinctively Rawlsian as justice as fairness itself.

The two leading traditions of theorizing about democratic legitimacy are liberalism and deliberative democracy. Liberals typically claim that legitimacy consists in the consent of the governed, while deliberative democrats typically claim that legitimacy consists in the soundness of political procedures. Despite this difference, both traditions see the need for legitimacy as arising from the coercive enforcement of law and regard legitimacy as necessary for law to have normative authority. While I endorse the broad aims of these two traditions, I believe (...) they both misunderstand the nature of legitimacy. In this essay I argue that the legitimacy of a law is neither necessary nor sufficient for its normative authority, and I argue further that the need for legitimacy in law arises regardless of whether the law is coercively enforced. I thus articulate a new understanding of the legitimacy and authority of law. (shrink)

The paper distinguishes between two conceptions of kinds defined by constitutive rules, the one suggested by Searle, and the one invoked by Williamson to define assertion. Against recent arguments to the contrary by Maitra, Johnson and others, it argues for the superiority of the latter in the first place as an account of games. On this basis, the paper argues that the alleged disanalogies between real games and language games suggested in the literature in fact don’t exist. The paper relies (...) on Rawls’s distinction between types of practices and institutions defined by constitutive rules, and those among them that are actually in force, and hence are truly normative; it defends along Rawlsian lines that a plurality of norms apply to actual instances of rule-constituted practices, and uses this Rawlsian line to block the examples that Maitra, Johnson and others provide to sustain their case.

The goal of this paper is a comprehensive analysis of basic reasoning patterns that are characteristic of vague predicates. The analysis leads to rigorous reconstructions of the phenomena within formal systems. Two basic features are dealt with. One is tolerance: the insensitivity of predicates to small changes in the objects of predication (a one-increment of a walking distance is a walking distance). The other is the existence of borderline cases. The paper shows why these should be treated as different, though (...) related phenomena. Tolerance is formally reconstructed within a proposed framework of contextual logic, leading to a solution of the Sorites paradox. Borderline-vagueness is reconstructed using certain modality operators; the set-up provides an analysis of higher order vagueness and a derivation of scales of degrees for the property in question.

Tarski’s conceptual analysis of the notion of logical consequence is one of the pinnacles of the process of defining the metamathematical foundations of mathematics in the tradition of his predecessors Euclid, Frege, Russell and Hilbert, and his contemporaries Carnap, Gödel, Gentzen and Turing. However, he also notes that in defining the concept of consequence “efforts were made to adhere to the common usage of the language of every day life.” This paper addresses the issue of what relationship Tarski’s analysis, and (...) Béziau’s further generalization of it in universal logic, have to reasoning in the everyday lives of ordinary people from the cognitive processes of children through to those of specialists in the empirical and deductive sciences. It surveys a selection of relevant research in a range of disciplines providing theoretical and empirical studies of human reasoning, discusses the value of adopting a universal logic perspective, answers the questions posed in the call for this special issue, and suggests some specific research challenges.
