Pluralism and its inner potential conflictuality is the main problem of political thought in the modern world, as the recent querelle between liberals and communitarians has significantly demonstrated. A different perspective emerges from the careful consideration of social interaction. The political body arises, when the pursuing of social communication itself is set as a common end - that is, when social communication institutes a permanent space of communication. Thus, a re-consideration of politics is possible through a re-thinking of human relationships. This opens the path to the possibility of a significative convergence towards the political aristotelism of the origins and with its notion of "natural sociality" of mankind: a tradition which indicates in the participation to the "useful" (a category which implies the virtue of justice) the proper ground for politics.
