Asks how, why and to what ends humans appear in international relations theories and how this makes us interpret world politics.This volume presents and advances the debate about how, why and to which ends ideas about humans are built into our theories and how we come to see world politics and humanity's role in it as a result. It is the first survey devoted to this subject in international relations.This volume presents and advances the debate about how, why and to which ends ideas about humans are built into our theories and how we come to see world politics and humanity's role in it as a result. It is the first survey devoted to this subject in international relations.Since the 1980s, the discipline of International Relations has seen a series of disputes over its foundations. However, there has been one core concept that, although addressed in various guises, had never been explicitly and systematically engaged with in these debates: the human. This volume is the first to address comprehensively the topic of the human in world politics. It comprises cutting-edge accounts by leading scholars of how the human is (or is not) theorized across the entire range of IR theories, old and new. The authors provide a solid foundation for future debates about how, why, and to which ends the human has been or must (not) be built into our theories, and systematically lay out the implications of such moves for how we come to see world politics and humanity's role within it.Introduction: human being(s) in international relations Daniel Jacobi and Annette Freyberg-Inan; Part I.
