Current endeavours to develop a ‘realistic’ concept of international law should take into account that there is not only one reality. It does not suffice to admit that reality can be perceived from different angles. Rather, a realistic account of modern society has to acknowledge that we can no longer speak of the ‘world’ or ‘reality’ as a singular entity. Perspectives matter; they construct their own, distinct objects of cognition. A ‘New Legal Realism’ is deliberately new, legal, and realistic only insofar as it is conceived as an understanding of how (international) law creates its own realities.
