Chapter 8, The Individual Human Being as a Category – A Conclusion and an Outlook, returns to theory. To this end, the chapter weaves together the results of the case studies and the theoretical and methodological considerations. The chapter, serving as a conclusion to the book, simultaneously summarises the book, revisits the issue of interdisciplinarity, and presents its results. It also discusses the book’s contribution and value added. Most importantly, it demonstrates how the results of the empirical case studies are relevant for IR theory and what implications for IR theory, IL scholarship, and the study of global politics can be derived from these results. Finally, the chapter outlines future research based on the book’s results.
