A theme of growing importance in both the law and philosophy and socio-legal literature is how regulatory dynamics can be identified (that is, conceptualised and operationalised) and normative expectations met in an age when transnational actors operate on a global plane and in increasingly fragmented and transformative contexts. A reconsideration of established theories and axiomatic findings on regulatory phenomena is an essential part of this discourse. There is indeed an urgent need for discontinuity regarding what we (think we) know about, among other things, law, legality, sovereignty and political legitimacy, power relations, institutional design and development, and pluralist dynamics of ordering under processes of globalisation and transnationalism. Making an important contribution to the scholarly debate on the subject, this volume features original and much-needed essays of theoretical and applied legal philosophy as well as socio-legal accounts that reflect on whether legal positivism has anything to offer to this intellectual enterprise. This is done by discussing whether global and transnational cultural, socio-political, economic, and juridical challenges as well as processes of diversification, fragmentation, and transformation (significantly, de-formalisation) reinforce or weaken legal positivists’ assumptions, claims, and methods. The themes covered include, but are not limited to, absolute and limited state sovereignty; the ‘new international legal positivism’; Hartian legal positivism and the ‘normative positivist’ account; the relationship between modern secularisation, social conventionalism, and meta-ontological issues of temporality in postnational jurisprudence; the social positivisation of human rights; the formation and content of jus cogens norms; feminist critique; the global and transnational migration of principles of justice and morality; the Vienna Convention on the Law of Treaties rule of interpretation; and the responsibility of transnational corporations.

Legal Positivism has been the dominant school of legal philosophy for much of the last century, despite its many critics. Its central tenet has long been that there is no necessary connection between law and morality. This book provides a broad but clear and jargon-free account of the central objections to the theory and why those objections are sufficient to show that legal positivism is no longer tenable. This includes a broad critique of the purported distinction method of legal positivism, the idea of ‘conceptual analysis,’ as well as a detailed assessment of the most influential of all legal positivist theories, that of H.L.A. Hart. The book also provides a defense of the natural law school, which holds in contrast to legal positivism that the authority of law arises from its intrinsic connection to morality. The author demonstrates that most of the criticism of the natural law school arises from a caricatured account of that doctrine, for instance the idea that it requires substantive theological commitments or particular conceptions of human nature. In contrast, the author presents an account of natural law theory that is grounded in a commitment to moral truth, but not to any theological beliefs. The nature of law can only be understood in terms of its moral function, to provide a clear set of moral rules that are required for a society to function effectively.

Hans Kelsen and the Natural Law Tradition provides the first sustained examination of Hans Kelsen’s critical engagement, itself founded upon a distinctive theory of legal positivism, with the Natural Law Tradition. This edited collection commences with a comprehensive introduction which establishes the character of Kelsen’s critical engagement as a general critique of natural law combined with a more specific critique of representative thinkers of the Natural Law Tradition. The subsequent chapters are then devoted to a detailed analysis of Kelsen’s engagement with prominent theorists from the Natural Law Tradition. The volume concludes with an exploration, focusing upon the delineation of a non-positivist legal theory in the debate between Robert Alexy and Joseph Raz, of the continued presence of Kelsenian legal positivism in contemporary legal theory.

This book provides a major review of the state of international theory. It is focused around the issue of whether the positivist phase of international theory is now over, or whether the subject remains mainly positivistic. Leading scholars analyse the traditional theoretical approaches in the discipline, then examine the issues and groups which are marginalised by mainstream theory, before turning to four important new developments in international theory (historical sociology, post-structuralism, feminism, and critical theory). The book concludes with five chapters which look at the future of the subject and the practice of international relations. This survey brings together key figures who have made leading contributions to the development of mainstream and alternative theory, and will be a valuable text for both students and scholars of international relations.

The book brings together 33 state-of-the-art chapters on the import and the pros and cons of legal positivism.

What is law? This question has preoccupied philosophers from Plato to Thomas Hobbes to H. L. A. Hart. Yet many others find it perplexing. How could we possibly know how to answer such an abstract question? And what would be the point of doing so? In Legality, Scott Shapiro argues that the question is not only meaningful but vitally important. In fact, many of the most pressing puzzles that lawyers confront—including who has legal authority over us and how we should interpret constitutions, statutes, and cases—will remain elusive until this grand philosophical question is resolved. Shapiro draws on recent work in the philosophy of action to develop an original and compelling answer to this age-old question. Breaking with a long tradition in jurisprudence, he argues that the law cannot be understood simply in terms of rules. Legal systems are best understood as highly complex and sophisticated tools for creating and applying plans. Shifting the focus of jurisprudence in this way—from rules to plans—not only resolves many of the most vexing puzzles about the nature of law but has profound implications for legal practice as well. Written in clear, jargon-free language, and presupposing no legal or philosophical background, Legality is both a groundbreaking new theory of law and an excellent introduction to and defense of classical jurisprudence.

International Legal Positivism in a Post-Modern World provides fresh perspectives on one of the most important and most controversial families of theoretical approaches to the study and practice of international law. The contributors include leading experts on international legal theory who analyse and criticise positivism as a conceptual framework for international law, explore its relationships with other approaches and apply it to current problems of international law. Is legal positivism relevant to the theory and practice of international law today? Have other answers to the problems of international law and the critique of positivism undermined the positivist project and its narratives? Do modern forms of positivism, inspired largely by the theoretically sophisticated jurisprudential concepts associated with Hans Kelsen and H. L. A. Hart, remain of any relevance for the international lawyer in this 'post-modern' age? The authors provide a wide variety of views and a stimulating debate about this family of approaches.
