"Bertrand Badie is one of France’s leading authorities on international relations. In this short but incisive book he shows that, while material trends matter, they are always subject to battles over meaning. His subtlety and effortless interdisciplinarity make his account valuable for students and scholars alike."Christopher Hill, University of Cambridge"Badie offers a radical and compelling challenge to realists and constructivists alike. He makes the case that serious attention to the values and practices of different actors can promote a more useful understanding of the fragility of international society and its ordering. International relations should be not a science of power or a study of constitution but, rather, a hermeneutic sociology of relationships."Ned Lebow, Dartmouth College
