Emergence of the modern science of international law is usually attributed to Grotius and other somewhat heroic ‘founders of international law.’ This book offers a more worldly explanation why it was developed mostly by German writers in the seventeenth and eighteenth centuries.

Edward Keene argues that the conventional idea of an 'anarchical society' of equal and independent sovereign states is an inadequate description of order in modern world politics. International political and legal order has always been dedicated to two distinct goals: to try to promote the toleration of different ways of life, while advocating the adoption of one specific way, that it labels 'civilization'. The nineteenth-century solution to this contradiction was to restrict the promotion of civilization to the world beyond Europe. That discriminatory way of thinking has now broken down, with the result that a single, global order is supposed to apply to everyone, but opinion is still very much divided as to what the ultimate purpose of this global order should be, and how its political and legal structure should be organised.

This book seeks to analyse various aspects of international law, the link being how they structure and marshal the different forces in the international legal order. It takes the following approaches to the matter. First, an attempt is made to determine the fundamental characteristics of international law, the forces that delineate and permeate its applications. Secondly, the multiple relations between law and policy are analysed. Politics are a highly relevant factor in the implementation of every legal order (and also a threat to it); this is all the more true in international law, where the two forces, law and politics, have significant links. Thirdly, the discussion focuses on a series of fundamental socio-legal notions: the common good, justice, legal security, reciprocity (plus equality and proportionality), liberty, ethics and social morality, and reason.

For many centuries, thinkers have tried to understand and to conceptualize political and legal order beyond the boundaries of sovereign territories. Their concepts, deeply entangled with ideas of theology, state formation, and human nature, form the bedrock of todays theoretical discourses on international law. This volume engages with models of early international legal thought from Machiavelli to Hegel before international law in the modern sense became an academic discipline of its own. The interplay of system and order serves as a leitmotiv throughout the book, helping to link historical models to contemporary discourse. Part I of the book covers a diverse collection of thinkers in order to scrutinize and contextualize their respective models of the international realm in light of general legal and political philosophy. Part II maps the historical development of international legal thought more generally by distilling common themes and ideas, such as the relationship between universality and particularity, the role of the state, the influence of power and economic interests on the law, and the contingencies of time, space and technical opportunities. In the current political climate, where it appears that the reinvigorated concept of the nation state as an ordering force competes with internationalist thinking, the problems at issue in the classic theories point to contemporary questions: is an international system without central power possible? How can a normative order come about if there is no central force to order relations between states? These essays show that uncovering the history of international law can offer ways in which to envisage its future.

This analysis of Hans Kelsen's international law theory takes into account the context of the German international legal discourse in the first half of the twentieth century, including the reactions of Carl Schmitt and other Weimar opponents of Kelsen. The relationship between his Pure Theory of Law and his international law writings is examined, enabling the reader to understand how Kelsen tried to square his own liberal cosmopolitan project with his methodological convictions as laid out in his Pure Theory of Law. Finally, Jochen von Bernstorff discusses the limits and continuing relevance of Kelsenian formalism for international law under the term of 'reflexive formalism', and offers a reflection on Kelsen's theory of international law against the background of current debates over constitutionalisation, institutionalisation and fragmentation of international law. The book also includes biographical sketches of Hans Kelsen and his main students Alfred Verdross and Joseph L. Kunz.

This unique collection presents texts in international relations from Ancient Greece to the First World War. Major writers such as Thucydides, Augustine, Aquinas, Machiavelli, Grotius, Kant and John Stuart Mill are represented by extracts of their key works; less well-known international theorists including John of Paris, Cornelius van Bynkershoek and Friedrich List are also included. Fifty writers are anthologised in what is the largest such collection currently available. The texts, most of which are substantial extracts, are organised into broadly chronological sections, each of which is headed by an introduction that places the work in its historical and philosophical context. Ideal for both students and scholars, the volume also includes biographies and guides to further reading.
