Between Truth, Legitimacy, and Legality in the post-Truth Era

The starting point is the strong feeling that today we are not faced with some accidental and transitory "pathologies" of communication (fake news, infodemic ...) but with some communication patterns which are part of a new, discursive regime (in the Foucauldian sense) that has changed in depth and that must be studied in its systemic aspects. We are facing a profound epistemic change, not a moment of confusion; and the change has to do with the technological, and consequently informational and ontological, changes that all the great 'industrial' revolutions entail. In order to argue about the characteristics of these changes, first of all I will outline the old categories that are no longer suitable for the new regime; then I will outline two new models which in my opinion are becoming widespread and are more adequate to the “new” reality; finally, I will suggest a sort of alternative to our traditional criterion of truth: the criterio of legitimacy, in order to rethink those of correctness, objectivity, adequacy.
