Recovering International Relations bridges two key divides in contemporary IR: between value-free and normative theory, and between reflective, philosophically inflected explorations of ethics in scholarship and close, empirical studies of practical problems in world politics. Featuring a novel, provocative and detailed survey of IRs development over the second half of the twentieth century, the work draws on early Frankfurt School social theory to suggest a new ethical and methodological foundation for the study of world politics-sustainable critique-which draws these disparate approaches together in light of their common aims, and redacts them in the face of their particular limitations. Understanding the discipline as a vocation as well as a series of academic and methodological practices, sustainable critique aims to balance the insights of normative and empirical theory against each other. Each must be brought to bear if scholarship is to meaningfully, and responsibly, address an increasingly dense, heavily armed, and persistently diverse world.
