This paper analyses an approach of International Political Sociology (IPS) inspired by a relational and processual methodology, questioning the assumptions of International Relations concerning the boundaries of the international, the vision of politics at the core of political sciences, and the methodological nationalism concerning society. In order to avoid dualisms, IPS discusses the different episteme at work and analyses the socio genesis of the practices of actors in their different professional and cultural universes, looking specifically to their struggles for power and to the processes of politicisation and (in)securitisation. IPS is therefore constructivist in the sense that its authors are reflexive and deconstruct essentialist claims to knowledge. IPS is also empiricist inasmuch as the authors a re sensitive to the practices of human beings and their relationships to objects, and start their theories from these sociological and historical relationships always embedded in specific locations and time. Of course empiricism does not mean positivism, and constructivism does not mean an idealistic perspective where norms, ideas and beliefs lead the world. The aim of this perspective is to decolonize the study of practices of the "transnational societies of individuals" from the so-called great debates of the Anglo-American visions, reproduced in their philosophies and approaches of social sciences.
