Hey guys, I am currently working on a PhD proposal. It is focused on the added value of the sociology of Max Weber for the study of International Relations (IR). However, I struggle with methodology. I think there is a lot in Weberian sociology that can be of great benefit for the study of IR, but I just can't figure out how I would do research on such a highly theoretical topic. Can anyone help? Does anyone have any ideas about how to work on a theoretical subject like this in terms of methodology? Thank you very much! H.
