In this reply, I try to clarify the theoretical project behind the book and respond to the critical remarks of my interlocutors. Above all, I try to illustrate what are the possible answers to the objections of a politico-philosophical nature that are made to the perspective of ‘cosmopolitan realism’, that is, cosmopolitanism without illusions, proposed by the text, and which concern the issues of ethnocentrism, the relationship with human rights, applicability and philosophical foundation.
