In this book Mark Neufeld argues that the predominance of the positivist approach to the study of international politics has meant that theory committed to human emancipation remains poorly developed. He suggests that International Relations theory must move in a non-positivist direction, and takes recent developments in the discipline (including Gramscian, postmodernist, feminist and normative approaches) as evidence that such a shift is already under way. In a comprehensive treatment, he argues that the critical theory of the Frankfurt School can be used to reorient the study of world politics. Drawing on recent work in social and political theory, as well as International Relations, this book offers an accessible analysis of recent developments in the study of international politics.
