In their essay, they shed light on presuppositions of Western knowledge production and its gatekeeper role in research practice, highlighted by the context of communication studies.

With recourse to Isabelle Stenger's idea of the "cosmos", they recontextualize the concept of cosmopolitanism and discuss its (im)possibilities for the de-westernization of (German) science.
