Critical international theory has the task of providing orientation to human beings in better understanding their conditions of existence, how those conditions came to assume their contemporary characteristics, and what immanent potential they might hold for emancipatory transformation. The argument in this book is that this task of orientation is indissociable from a reliance on grand narratives that capture the main features of the long-term process of human development. And yet, many of these grand narratives also tend to reproduce Eurocentric worldviews that undermine critical international theory's reliability as a means of orientation. In this book, André Saramago provides an innovative answer to the problem of orientation with which critical international theory is confronted. Through an indepth engagement with the work of Jürgen Habermas, Karl Marx, and Norbert Elias, he recovers a historical-sociological approach to grand narratives that avoids a reproduction of their Eurocentric shortcomings. In the process, he improves critical international theory's role as a means of orientation by making it better theoretically equipped to capture the interweaving of the historical development of the human capacity for self-determination in the four key dimensions of human existence: people's relations with themselves as individuals; social relations at both the intra- and inter-societal levels; and people's relations with non-human nature. This book will appeal to all students and researchers interested in interdisciplinary and critical approaches to the study of world politics, long-term processes of social change, and human-nature relations, working within or across the fields of International Relations, Sociology, Political Theory, and related areas of inquiry.
