This superbly conceived and masterfully executed Handbook is a must-read for every scholar and student of International Relations with any serious concern for how knowledge is gained, curated, contested, and deployed in the conflicting worlds of international thought, practice, and action. That this is the new state of the art in the social and political epistemology of international politics brings the exhilarating and comforting realisation that we have, at last, forged a homegrown self-knowledge fit for the realities and challenges of the twenty-first century.
