Abstract
The aim of this essay is to offer a critical interpretation of the question of borders and neo-nationalism, according to two perspectives. The first, which is geo-philosophical, critically deconstructs the concept of border as an immune barrier; the second, which is genealogical, rethinks the question of what I will call neo-patriotism, starting from some previous manifestations of nationalist patriotism, in particular in the 1930s. Both perspectives would like to solicit reflection on a different organization of the great world spaces, in the direction of a universalism. It is about thinking of an inclusive and not exclusionary pluriverse, in which differences are not foreclosed, but are recognized.
