The experimental turn in philosophy has reached several sub-fields including ethics, epistemology, and metaphysics. This paper is among the first to apply experimental techniques to questions in the philosophy of law. Specifically, we examine Lon Fuller's procedural natural law theory. Fuller famously claimed that legal systems necessarily observe eight principles he called "the inner morality of law." We evaluate Fuller's claim by surveying both ordinary people and legal experts about their intuitions about legal systems. We conclude that, at best, we (...) should be skeptical of Fuller's inner morality of law in light of the experimental data. (shrink)

This chapter discusses two different issues about the relationship between legal positivism and robust normativity (understood as the most authoritative kind of normativity to which we appeal). First, the chapter argues that, in many contexts when discussing “legal positivism” and “legal antipositivism”, the discussion should be shifted from whether legal facts are ultimately partly grounded in moral facts to whether they are ultimately partly grounded in robustly normative facts. Second, the chapter explores an important difference within the kinds of arguments (...) that legal philosophers give for the (purported) truth of legal positivism. The difference concerns whether (purportedly) robustly normative facts are appealed to as premises in those arguments or not. (A closely connected issue is whether (purportedly) normative facts that bear one or more important connections to robustly normative facts are appealed to in premises to those arguments.) The chapter argues that thinking about this dividing line helps people better situate the positivist/antipositivist dispute, better understand the space of views in legal philosophy, better evaluate those views, and avoid having merely verbal disputes.

In this book, I present the results of an investigation which began with an extended stay at Oxford's Balliol College during the first half of 1995. My visit to Oxford was made possible by a grant from the Spanish Ministerio de Educaci6n y Ciencia. My sincere thanks go to Joseph Raz who served as my supervisor in Oxford. For several points of the present study, conversations with Timothy Endicott in Oxford were also of great help. The book is part of (...) a larger project of investigation, directed by Albert Calsami glia, which is a joint effort of a group of legal philosophers from the Universitat Pom peu Fabra and the Universitat de Girona, and which also receives financial support from the Spanish Ministerio de Educaci6n y Ciencia. An earlier version of the manuscript was presented in June 1996 to the selection committee for a tenured professorship in Legal Philosophy at the Universitat de Girona. The members of the committee were Francisco Laporta, Albert Calsamiglia, Gregorio Peces-Barba, Camilo J. Cela Conde, and Francesca Puigpelat. I am grateful to all of them for their comments, which have been extremely useful in preparing the final ver sion of this book. (shrink)

In this paper I put forward some arguments in defence of inclusive legal positivism . The general thesis that I defend is that inclusive positivism represents a more fruitful and interesting research program than that proposed by exclusive positivism . I introduce two arguments connected with legal interpretation in favour of my thesis. However, my opinion is that inclusive positivism does not sufficiently succeed in estranging itself from the more traditional legal positivist conceptions. This is the case, for instance, with (...) regard to the value-freedom principle, which is commonly accepted by inclusive positivist scholars. In contrast with this approach, I try to show, in the concluding section, how a constructivistic version of inclusive positivism could legitimately acknowledge the presence of value-judgments in the cognitive activities of jurists and legal theorists.

According to a widely held view, people's commitments to laws are dependent on the existence in their community of a conventional practice of complying with certain fundamental laws. This conventionalism has significantly hampered our attempts to explain the normative practice of law. Ronald Dworkin has argued against conventionalism by bringing up the phenomenon of persistent fundamental legal controversies, but neither Dworkin nor his legal positivist respondents have correctly understood the real significance of such controversies. This article argues that such controversies (...) pose a deep challenge to any conception of our legal practice as a genuinely normative, rule-mediated, practice. The article also argues that what is needed to deflect this challenge is a new understanding – different from the widely held conventionalist understanding – of how people's commitments to laws are predicated on their fellows’ like commitments.

According to the received opinion there is a theoretical incompatibility between Herbert Hart's The Concept of Law and Alf Ross's On Law and Justice, and, according to the received opinion, it stems above all from Hart's emphasis on the internal point of view. The present paper argues that this reading is mistaken. The Concept of Law does not go beyond On Law and Justice in so far as both present arguments to the effect that law is based on a shared (...) understanding between participants in a project perceived by every participant to be a project in common. The paper demonstrates that there are substantive parallels between Hart's combination of “acceptance” or “acknowledgement” and a “critical reflective attitude” and Ross's combination of “motivation” or “feeling” and a “coherent whole of meaning and motivation.” The main conclusion is that the views of norms and normativity put forward in The Concept of Law and On Law and Justice are very close in essential respects, and, more specifically, that the two works are at root identical in their representation of the basis of normativity in reality.

The passage of time influences the content of the law and therefore also the validity of legal arguments. This is true even for charter-arguments, despite the widely held view that constitutional law is made to last. In this paper, I investigate the reason why the sanctity-of life argument against physician assisted suicide lost its validity between the Supreme Court decision in Rodriguez v. British Columbia in 1993 and Carter v. Canada in 2015. I suggest that a rhetorical approach to argument (...) evaluation is the best basis for a satisfying explanation. (shrink)

In this article, I distinguish between a moral and a strictly legal conception of legal normativity, and argue that legal positivists can account for law's normativity in the strictly legal but not in the moral sense, while pointing out that normativity in the former sense is of little interest, at least to lawyers. I add, however, that while the moral conception of law's normativity is to be preferred to the strictly legal conception from the rather narrow viewpoint of the study (...) of law's normativity, it is less attractive than the latter from the broader viewpoint of the study of the nature of law. I then distinguish between a moral and a strictly legal conception of the normative force of legal justification, and argue that legal positivists may without contradiction embrace the moral conception, and that therefore the analysis of the normative force of legal justification need not be a problem for legal positivists. I conclude that, on the whole, we have reason to prefer legal positivism to natural law theory. I begin by introducing the subject of jurisprudence . I then introduce the natural law/legal positivism debate, suggesting that we ought to understand it as a debate about the proper way to explicate the concept of law . I proceed to argue that legal decision‐making is a matter of applying legal norms to facts, and that syllogistic reasoning plays a prominent role in legal decision‐making thus conceived . Having done that, I discuss law's normativity , the normative force of legal justification , and the relation between the former and the latter . I conclude with a critical comment on Joseph Raz’ understanding of the question of law's normativity. (shrink)

The Scandinavian Realist Karl Olivecrona did not pay much attention to questions of legal reasoning in his many works. He did, however, argue that courts necessarily create law when deciding a case. The reason, he explained, is that judges must evaluate issues of fact or law in order to decide a case, and that evaluations are not objective. Olivecrona's line of argument is problematic, however. The problem is that Olivecrona uses the term "evaluation" in a sense that is broad enough (...) to cover not only evaluations, including moral evaluations, but also considerations that are not evaluations at all, and therefore his claim that judges must evaluate issues of law or fact in order to decide whether a case is false.

In this article, I discuss Alf Ross's claim that the concept of a legal right is best understood as a technical tool of presentation, which ties together a disjunction of operative facts and a conjunction of legal consequences, and that rights statements render the content of a number of legal norms in a convenient manner. I argue that while Ross's analysis is appealing, it is problematic in at least three respects. I also argue, however, that despite these difficulties Ross's analysis (...) deserves our continued attention, because the fundamental idea—that the concept of a legal right must be understood functionally—is sound.

El problema de los desacuerdos jurídicos puede ser planteado de diferentes modos. En una de sus versiones, el problema viene dado porque el positivismo asume que los conceptos jurídicos son criteriológicos, por lo que el desacuerdo entre juristas carece de sentido al ser una disputa meramente verbal. Plunkett y Sundell han ofrecido una respuesta novedosa a esta crítica que sostiene que no hace falta compartir un concepto para discrepar con sentido. En este trabajo analizaré esa respuesta y ofreceré una serie (...) de críticas contra ella. (shrink)

The essay discusses the import of the separability thesis both for legal positivism and for contemporary legal practice. First, the place of the separability thesis in legal positivism will be explored, distinguishing between “standard positivism” and “post‐Hartian positivism.” Then I will consider various kinds of relations between law and morality that are worthy of jurisprudential interest, and explore, from a positivist point of view, what kind of relations between law and morality must be rejected, what kind of such relations should (...) be taken into account, and what kind of such relations are indeed of no import at all. The upshot of this analysis consists in highlighting the distinction between two different dimensions of legal validity (formal validity and material validity respectively), and in pointing out that the positivist separability thesis can apply to formal validity only. On the other hand, when the ascertainment of material validity is at stake, some form of moral reasoning may well be involved (here and now, it is necessarily involved). The essay concludes with some brief remarks on the persisting importance of the positivist jurisprudential project. (shrink)

¿Cómo justificar la validez jurídica de aquellas normas cuya creación no puede ser evaluada como regular o irregular por apelación a ninguna otra norma jurídica? Entre las respuestas más ilustres a este problema se cuentan la norma fundante kelseniana y la regla de reconocimiento de Hart, pero cada una de esas ideas ha sido objeto de serias críticas. Eugenio Bulygin ha efectuado aportes decisivos en esta discusión: ha advertido que cuando se examina el fundamento último de la validez de las (...) normas jurídicas es preciso discriminar un sentido prescriptivo y uno descriptivo de validez, y que la norma fundante de Kelsen no es sino el producto de una confusión entre ambos; ha resaltado que la regla de reconocimiento debe interpretarse como una regla conceptual que especifica los criterios de identificación de las normas jurídicas, y ha señalado que las normas de competencia no pueden reconstruirse como normas de conducta. Si bien con tales aportes ha sentado las bases para ofrecer una solución, su reconstrucción requiere de ciertas precisiones para poder ser considerada una respuesta enteramente satisfactoria a la pregunta respecto del fundamento último de la validez jurídica. How is it possible to ground the legal validity of those rules whose creation cannot be assessed as regular or irregular by reference to any other legal rule? Kelsen's basic norm and Hart's rule of recognition are among the most famous answers to this question, but both ideas have been seriously challenged. Eugenio Bulygin has made decisive contributions to this discussion. He has shown that in the analysis of the ultimate ground of validity of legal rules, two different senses of validity should be distinguished: a prescriptive and a descriptive sense, and that the Kelsenian basic norm is nothing but the product of confusion between these two different senses. He has also claimed that the rule of recognition has to be understood as a conceptual rule specifying the criteria of identification of legal rules, and those power-conferring rules cannot be interpreted as prescriptive norms of conduct. Although these contributions have provided a basic framework for a possible solution, Bulygin's ideas need a refinement in order to be considered as a satisfactory answer to the question concerning the ultimate ground of legal validity.

Legal positivism's ``separation thesis'' is usually taken in one of two ways: as an analytic claim about the nature of law – roughly, as some version of the Social Thesis; or as a substantive claim about the moral value of law – roughly, as some version of the Value Thesis. In this paper I argue that we should recognize a third kind of positivist separation thesis, one which complements, but is distinct from, positivism's analytic and moral claims. The Neutrality Thesis (...) says that the correct analytic claim about the nature of law does not by itself entail any substantive claims about the moral value of law. I give careful formulations of these three separation theses, explain the relationships between them, and sketch the role that each plays in the positivist approach to law. (shrink)

El presente trabajo trata de hacer una defensa de una particular versión de positivismo jurídico excluyente como teoría que mejor describe el derecho y sus referencias a la moral. Aunque se reivindica la tesis de las fuentes como la tesis iuspositivista por excelencia, el quid de la defensa se asienta sobre un análisis de los diferentes tipos y conceptos de moral que se consideran relevantes a la hora de la identificación del derecho. La posibilidad del error en el descubrimiento de (...) la moral objetiva deja campo abierto para entender que el derecho no puede quedar determinado por otra cosa que no sean hechos sociales.

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 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.

Near the end of the last century, some legal philosophers adapted the so called causal theories of reference to solve internal problems in legal theory. Among those philosophers, Nicos Stavropoulos adjusted Hilary Putnam’s semantic externalism claiming it as a better philosophical view than legal positivism defended by Herbert Hart. According to him, what determines the correct application of a legal rule must be determined by the objects themselves. In that case, what determines the reference of legal terms is an issue (...) to be solved by the best theory developed. However, this is not the case necessarily: Hart’s model can reach to the same conclusions as an externalist adjustment of law. Furthermore, the epistemic criteria required by Putnam to deal with value judgements are also acceptable in a positivist model. This paper presents the central thesis of Putnam’s semantic externalism, with Stavropoulos adaptations to law, and defends that Hart’s approach to deal with legal rules and Putnam’s approach to deal with language rules can converge.

El positivismo jurídico como teoría sobre la existencia del derecho: un comentario sobre Judging Positivism de Margaret Martin Este comentario examina de forma crítica la concepción de positivismo jurídico que informa el desafío planteado por Margaret Martin contra la substancia y el método de esta tradición intelectual. La afirmación central de este artículo es que su caracterización de la teoría substantiva del positivismo jurídico deja de lado una dimensión más fundamental, y explicativamente previa, relacionada a la teoría positivista de la (...) existencia de los sistemas y normas jurídicas. También sostengo que su caracterización de la metodología descriptiva del positivismo como un proyecto no normativo es demasiado exigente y no puede capturar la relaciones entre derecho y moral reconocidas por los positivistas contemporáneos ni la distinción entre preguntas internas y externas. Estas clarificaciones proporcionan recursos para comenzar a responder algunas de las objeciones de Martín contra el proyecto de Raz. (shrink)

This paper guides the reader through the use of functions in contemporary legal philosophy: in developing those philosophies and through methodological debates over their proper role. This paper is broken into two sections. In the first I canvass the role of functions in the legal philosophies of several mid to late twentieth century Anglo-American general jurisprudents whose theories are still common topics of discussion: Ronald Dworkin, H.L.A. Hart, Lon L. Fuller, John Finnis, and Joseph Raz. In the second, I examine (...) contemporary arguments over the role of functions in the methodology of legal philosophy. (shrink)

This is a canvass to the critical reaction to Joseph Raz’s service conception of authority, as well as actual or possible replies by Raz. Familiarity is assumed with the theory itself, covered in a previous article. The article focuses primarily on direct criticisms of Raz’s theory, rather than replies developed in the context of a theorist’s wider project.

In this essay, I characterize the original intervention that became Inclusive Legal Positivism, defend it against a range of powerful objections, explain its contribution to jurisprudence, and display its limitations and its modest jurisprudential significance. I also show how in its original formulations ILP depends on three notions that are either mistaken or inessential to law: the separability thesis, the rule of recognition, and the idea of criteria of legality. The first is false and is in event inessential to legal (...) positivism. The second is inessential to legal positivism. The third is likely inessential to law. I then characterize the central claim of ILP in a way that relies on none of these: ILP is the claim that necessarily social facts determine the determinants of legal content. I show that ILP so conceived leaves the central debates in law largely untouched. I suggest how the most fundamental of these—the question of the normativity of law—at least can be usefully addressed. The essay closes by suggesting that even though one can distinguish the social from the normative dimensions of law, a theory of the nature of law is necessarily an account of the relationship between the two: It is a theory either of the difference that certain distinctive social facts make in normative space, or it is an account of the distinctive normative difference that law makes, and the social and other facts that are necessary to explain that difference. One can distinguish between but one cannot separate the social from the normative aspects of legality. (shrink)

The goal of this paper is to provide an accurate grounding-based formulation of positivism in the philosophy of law. I start off by discussing some simple formulations, based on the ideas that social facts are always either full or partial grounds of legal facts. I then raise a number of objections against these definitions: the full grounding proposal rules out possibilities that are compatible with positivism; the partial grounding proposal fails, on its own, to vindicate the distinctive role that is (...) played by social facts within positivist accounts of law. Then, I present a more adequate and insightful formulation capable of solving their problems, which crucially relies on a robust notion of a social enabler. Finally, I model inclusive and exclusive positivism on the resulting template, and set out the advantages of the ground-enablers proposal. (shrink)

The article presents a vision of the challenges to which contemporary legal positivism has to respond. The constitutionalisation that governs current legal systems offers a new framework in which to develop the classic controversy between positivism and iusnaturalism. This article analyses the different positivist proposals put before the reality of the constitutional state as well as its replies to the criticisms of those who consider it anoutdated theory of little use. Finally, it will also deal with the relationship between positivism (...) and legal realism. This relationship is increasingly close due to the uncertainty that characterizes no few legislative and constitutional clauses. (shrink)

Speech and thought about what the law is commonly function in practical ways, to guide or assess behavior. These functions have often been seen as problematic for legal positivism in the tradition of H.L.A. Hart. One recent response is to advance an expressivist analysis of legal statements (Toh), which faces its own, familiar problems. This paper advances a rival, positivist-friendly account of legal statements which we call “quasi-expressivist”, explicitly modeled after Finlay’s metaethical theory of moral statements. This consists in a (...) descriptivist, “rule-relational” semantics combined with a pragmatic account of the expressive and practical functions of legal discourse. We argue that this approach is at least as well-equipped as expressivism to explain the motivational and prescriptive features of “internal” legal statements, as well as a fundamental kind of legal disagreement, while being better positioned to account for various “external” uses of the same language. We develop this theory in a Hartian framework, and in the final part of the paper argue (particularly against Toh’s expressivist interpretation) that Hart’s own views in The Concept of Law are best reconstructed along such quasi-expressivist lines.

The “naturalistic turn” that has swept so many areas of philosophy over the past three decades has also had an impact in the last decade in legal philosophy. Methodological naturalists (M-naturalists) view philosophy as continuous with empirical inquiry in the sciences. Some M-naturalists want to replace conceptual and justificatory theories with empirical and descriptive theories; they take their inspiration from more-or-less Quinean arguments against conceptual analysis and foundationalist programs. Other M-naturalists retain the normative and regulative ambitions of traditional philosophy, but (...) emphasize that it is an empirical question what normative advice is actually useable and effective for creatures like us. Some M-naturalists are also.. (shrink)

El profesor Juan Carlos Bayón ha sostenido que el positivismo incluyente resultaría inaceptable por apoyarse en la idea de una convención social de seguir criterios no convencionales: si hubiera acuerdo sobre el contenido de esos criterios, ellos resultarían convencionales, y sin acuerdo, no habría práctica social convergente y, por ende, no habría en realidad una regla convencional. Así, el positivismo incluyente quedaría enfrentado a un dilema: o bien resulta indistinguible del positivismo excluyente, o bien no es una postura convencionalista en (...) absoluto. Este trabajo evaluará la posibilidad de una salida al dilema. Para ello, se efectuará un análisis de las diversas versiones del positivismo incluyente y sus límites a la luz de la objeción planteada. También se intentará demostrar la viabilidad de un contraargumento centrado en los alcances de la tesis de la convencionalidad, que bloquearía la acusación de inconsistencia teórica esgrimida en su contra. Professor Juan Carlos Bayón has argued that Inclusive Legal Positivism should be rejected because its plausibility depends on the idea of a social convention to follow nonconventional criteria of validity. In his view, if there were agreement on the content of these criteria, it would be impossible to sustain its non-conventional character; and without agreement, there would not be a common social practice, and thus no social rule would exist. Therefore, Inclusive Positivism faces a dilemma: being indistinguishable from Exclusive Positivism or not being a genuine form of conventionalism at all. This article evaluates a possible way out of this dilemma. It explores the different versions of Inclusive Legal Positivism and its limits, and tries to build an opposing argument grounded on the scope of the conventionality thesis that would rescue Inclusive Legal Positivism from the accusation of theoretical inconsistency.
