Nowadays, the widespread view is that classical sociology is tainted with ‘methodological nationalism and it would appear that there has been a significant overlap between social and political space. We disagree with this point of view for three reasons: (1) by dealing with the global world, classical sociology has already glimpsed the possibility of going beyond the nation-state as a unit of analysis; (2) having operated above all with the notion of ‘social’ rather than ‘national’, its categories are transnational; and (3) when classical sociology has dealt with national society, studies have not reified it within its political boundaries. Consequently, in our opinion, classical sociology highlights both analytical categories that go beyond the ontology of the nation-state as well as new socio-political forms defined within the trajectory of modernity under the pressure of globalization processes.
