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)

After the publication of Hart's Concept of Law, Dworkin published his article “The Model of Rules,” dividing positivism into two varieties: inclusive and exclusive. Many theorists involved in this debate have characterized Hart's position as inclusivist, which we reject in this article. We argue that Hart, in the postscript to The Concept of Law, conceded a point to Dworkin in accepting that inclusive positivism would imply the existence of objective moral standing, adopting a more “neutral” position—compatible with inclusive and exclusive (...) positivism—and consequently distancing himself from the incorporation thesis, which is paramount to inclusive positivism.

Scott Shapiro, a prominent defender of exclusive legal positivism—exclusivism—has intriguingly (re)introduced a logical principle, the endorsement and rejection of which he (I take it) supposes can helpfully distinguish exclusivism from its contrary, inclusive legal positivism—inclusivism. It is an intriguing thought that principles pitched at such a high level of abstraction as this could distinguish between the two versions of positivism. My aim will be to test whether this principle—and associated principles—can do such distinguishing work.

Many contemporary practitioners of analytic jurisprudence take their understanding of legal positivism largely from Hart, and the debates about legal positivism exist largely in a post-Hartian world. But if we examine carefully the writings and motivations of Bentham and even Austin, we will discover that there are good historical grounds for treating both a normative version of positivism and a version more focused on legal decision-making as entitled to at least co-equal claims on the positivist tradition. And even if we (...) conceive of the inquiry in philosophical and not historical terms, there are reasons to doubt the view that a theory of the nature of law is the exclusive understanding of the core commitment of legal positivism. Positivism as a descriptive theory of the nature of law is important, but so too is positivism as a normative theory about the preferable attitude of society or theorists, and so too is positivism as a normative or descriptive theory of adjudication and other forms of legal decision-making. Those who understand positivism and the positivist tradition as being more normative or more adjudication-focused than the contemporary understanding allows are thus committing neither historical or philosophical mistakes, and little would be lost were we to recognize the multiple important contemporary manifestations of the legal positivist tradition.

Colemanand Shapiro have recently advanced a second at- tempt to reconcile Hart’s practice theory of rules and the idea of the normativity of law; i.e., the idea that legal rules qua social rules give reasons for actions and, in some circumstances create and impose duties and obligations. Their argumentative strategy is to resort to elements in Bratman’s work on shared agency and planning, though they introduce important and substantive modifications to Bratman’s own explanation. Bratman describes his own theory as a (...) modest theory of the will where the notion of planning plays a fundamental role. Both Shapiro’s and Coleman’s application of Bratman’s planning theory of agency to an authority structure such as law is impressive, but a number of objections can be levelled, with the intention of grasping both the nature of authority structures and the normativity of law. Although I have referred to Shapiro’s and Coleman’s applica- tions as being similar to one another, the differences are sub- stantive and important. I will scrutinise both Shapiro’s and Coleman’s explanations of ‘shared agency’ and discuss the objections that can be raised against each application. (shrink)

Positivismo jurídico normativo: de la metafísica a la política El presente trabajo toma como punto de partida el libro Positivismo jurídico “interno”, de María Cristina Redondo, y propone una concepción alternativa de positivismo jurídico normativista. Se sostiene que la teoría del derecho puede ser neutral en la medida en que sea intersubjetiva y transparente en cuanto a sus propias premisas metafísicas. Los objetivos del trabajo son el de echar luz acerca del papel de la metafísica y del sentido común en (...) la construcción del concepto de derecho, y el de hacer más abiertamente transparentes las elecciones ético-políticas que constituyen a los discursos jurídicos, incluidos los teóricos. El trabajo analiza las tesis de Redondo acerca de la distinción entre ontología y epistemología y la posibilidad de conocimiento objetivo: la idea central defendida es que la inter-subjetividad, y no la objetividad, debería ser el criterio apropiado para el positivismo jurídico normativista. Luego se examina el rol de la normatividad en el positivismo jurídico normativista, enfocándose en la naturaleza metafísica de la tesis de que el derecho pertenece a los campos de la normatividad y la razón práctica. Las secciones siguientes examinan las concepciones reduccionistas y anti-reduccionistas sobre las “entidades” jurídicas y la teoría de las fuentes del derecho. La sección final aborda la cuestión de la neutralidad valorativa de la teoría jurídica y analiza la posibilidad de describir el punto de vista interno de los participantes sin asumir compromiso alguno con la práctica jurídica existente.
