This book examines the crossroads of quantum and critical approaches to International Relations and argues that these approaches share a common project of uncovering complexity and uncertainty. The “quantum turn” in International Relations theory has produced a number of interesting insights into the complex ways in which our assumptions about the physics of the world around us can limit our understanding of social life. While critique is possible within a Newtonian social science, core assumptions of separability and determinism of classical physics impose limits on what is imaginable. The author argues that by adopting a quantum imaginary, social theory can move beyond its Newtonian limits, and explore two methods for quantizing conceptual models—translation and application. This book is the first introductory book to quantum social theory ideas specifically intended for an audience of critical International Relations.

A unique contribution to the understanding of social science, showing the implications of quantum physics for the nature of human society.

Written by world experts in the foundations of quantum mechanics and its applications to social science, this book shows how elementary quantum mechanical principles can be applied to decision-making paradoxes in psychology and used in modelling information in finance and economics. The book starts with a thorough overview of some of the salient differences between classical, statistical and quantum mechanics. It presents arguments on why quantum mechanics can be applied outside of physics and defines quantum social science. The issue of the existence of quantum probabilistic effects in psychology, economics and finance is addressed and basic questions and answers are provided. Aimed at researchers in economics and psychology, as well as physics, basic mathematical preliminaries and elementary concepts from quantum mechanics are defined in a self-contained way.

This new book unites in one volume some of the most prominent critiques of Alexander Wendt's constructivist theory of international relations and includes the first comprehensive reply by Wendt. Partly reprints of benchmark articles, partly new original critiques, the critical chapters are informed by a wide array of contending theories ranging from realism to poststructuralism. The collected leading theorists critique Wendt’s seminal book Social Theory of International Politics and his subsequent revisions. They take issue with the full panoply of Wendt’s approach, such as his alleged positivism, his critique of the realist school, the conceptualism of identity, and his teleological theory of history. Wendt’s reply is not limited to rebuttal only. For the first time, he develops his recent idea of quantum social science, as well as its implications for theorising international relations. This unique volume will be a necessary companion to Wendt’s book for students and researchers seeking a better understanding of his work, and also offers one of the most up-to-date collections on constructivist theorizing.

Critical international theory encompasses several distinct, radical approaches that focus on identity, difference, hegemonic power, and order. As an applied theory, critical international theory draws on critical social theories to shed light on international processes and global transformations. While this approach has led to increasing interest in formulating an empirically relevant critical international theory, it has also revealed the difficulties of applying critical theory to international politics. What are these difficulties and problems? And how can we move beyond them? This book addresses these questions by investigating the intellectual currents and key debates of critical theory, from Kant and Hegel to Habermas and Derrida, and the recent work of critical international theory, including Robert Cox and Andrew Linklater. By drawing on these debates, the book formulates an original theory of complementarity that brings together critical theory and critical international theory. It argues that complementarity—a governing principle in international law and politics—offers a conceptual framework for working toward two goals: engaging the changing contexts and forms of resistance and redressing some of the difficulties of applying critical theory to international relations. In adopting three critical perspectives on complementarity to analyze the evolving social and political contexts of global justice, this book provides an essential resource for undergraduate and graduate students and scholars interested in the application of critical theory to international relations.

While the relevance of ontological commitments for epistemology and methodology in International Relations have been the subject of growing debate for several years, the implications for ethics and political agency of embracing an ontology of entanglement have remained unexplored. This work focuses on the importance of addressing the ontological and epistemological assumptions of the discipline of International Relations. There is increased awareness of the limits of abstract principles as ways of adjudicating real life political and ethical choices regarding International Intervention and international development for both practitioners and scholars. The work challenges IR prevailing ontological imaginaries rooted upon Newtonian physics and argues that non-substantialist ontological positions nurture a political ethos that privileges ‘modest’ engagements of practical solidarity and weights political choices with regard to the consequences and distributive effects they may produce in the context where they are made rather than based upon their universal normative aspirations. While the book is firmly rooted in metatheory, Zanotti also highlights the easiness with which political failures are dismissed as unintended consequences and argues that the current crisis in Syria, and genocides in Srebrenica and Rwanda have shown that advocating abstract ethical principles, be they the Responsibility to Protect, impartiality, or following rules can lead to disaster and can foster violent and exclusionary practices. She also exemplifies how an alternative ethos can be practiced through the example of an international NGO in Haiti. Highlighting the need for critically re-thinking the way we conceptualize political agency and validate ethics, this work will be of interest to scholars of International Relations theory, ethics and critical security studies.

The Oxford Handbook of International Relations offers the most authoritative and comprehensive overview to date of the field of international relations. Arguably the most impressive collection of international relations scholars ever brought together within one volume, the Handbook debates the nature of the field itself, critically engages with the major theories, surveys a wide spectrum of methods, addresses the relationship between scholarship and policy making, and examines the field's relation with cognate disciplines. The Handbook takes as its central themes the interaction between empirical and normative inquiry that permeates all theorizing in the field and the way in which contending approaches have shaped one another. In doing so, the Handbook provides an authoritative and critical introduction to the subject and establishes a sense of the field as a dynamic realm of argument and inquiry. The Oxford Handbook of International Relations will be essential reading for all of those interested in the advanced study of global politics and international affairs.

Drawing upon philosophy and social theory, Social Theory of International Politics develops a theory of the international system as a social construction. Alexander Wendt clarifies the central claims of the constructivist approach, presenting a structural and idealist worldview which contrasts with the individualism and materialism which underpins much mainstream international relations theory. He builds a cultural theory of international politics, which takes whether states view each other as enemies, rivals or friends as a fundamental determinant. Wendt characterises these roles as 'cultures of anarchy', described as Hobbesian, Lockean and Kantian respectively. These cultures are shared ideas which help shape state interests and capabilities, and generate tendencies in the international system. The book describes four factors which can drive structural change from one culture to another - interdependence, common fate, homogenization, and self-restraint - and examines the effects of capitalism and democracy in the emergence of a Kantian culture in the West.

The agent-structure problem is a much discussed issue in the field of international relations. In his comprehensive 2006 analysis of this problem, Colin Wight deconstructs the accounts of structure and agency embedded within differing IR theories and, on the basis of this analysis, explores the implications of ontology - the metaphysical study of existence and reality. Wight argues that there are many gaps in IR theory that can only be understood by focusing on the ontological differences that construct the theoretical landscape. By integrating the treatment of the agent-structure problem in IR theory with that in social theory, Wight makes a positive contribution to the problem as an issue of concern to the wider human sciences. At the most fundamental level politics is concerned with competing visions of how the world is and how it should be, thus politics is ontology.

The contributors to this volume are motivated by a common apprehension and a common hope. The apprehension was first voiced by Einstein, who lamented the inability of humanity, at the individual and social level, to keep up with the increased speed of technological change brought about by the quantum revolution. As quantum science and technology fast forward into the 21st century, the social sciences remain stuck in classical, 19th century ways of thinking. Can such a mechanistic model of the mind and society possibly help us manage the fully realized technological potential of the quantum? That's where the hope appears: that perhaps quantum is not just a physical science, but a human science too. In Quantum International Relations, James Der Derian and Alexander Wendt gather rising scholars and leading experts to make the case for quantum approaches to world politics. As a fundamental theory of reality and enabler of new technologies, quantum now touches everything, with the potential to revolutionize how we conduct diplomacy, wage war, and make wealth. Contributors present the core principles of quantum mechanics--entanglement, uncertainty, superposition, and the wave function--as significant catalysts and superior heuristics for an accelerating quantum future. Facing a reality which no longer corresponds to an outdated Newtonian worldview of states as billiard balls, individuals as rational actors or power as objective interest, Der Derian and Wendt issue an urgent call for a new human science of quantum International Relations. At the centenary of the first quantum thought experiment in the 1920s, this book offers a diversity of explorations, speculations and approaches for understanding geopolitics in the 21st century.
