Deliberately eschewing disciplinary and temporal boundaries, this volume makes a major contribution to the de-traditionalization of political thinking within the discourses of international relations. Collecting the works of twenty-five theorists, this Ashgate Research Companion engages some of the most pressing aspects of political thinking in world politics today. The authors explore theoretical constitutions, critiques, and affirmations of uniquely modern forms of power, past and present. Among the themes and dynamics examined are textual appropriation and representation, materiality and capital formation, geopolitical dimensions of ecological crises, connections between representations of violence and securitization, subjectivity and genderization, counter-globalization politics, constructivism, biopolitics, post-colonial politics and theory, as well as the political prospects of emerging civic and cosmopolitan orders in a time of national, religious, and secular polarization. Radically different in their approaches, the authors critically assess the discourses of IR as interpretive frames that are indebted to the historical formation of concepts, and to particular negotiations of power that inform the main methodological practices usually granted primacy in the field. Students as well as seasoned scholars seeking to challenge accepted theoretical frameworks will find in these chapters fresh insights into contemporary world-political problems and new resources for their critical interrogation.
