Logique de l’information et sémiotique de la culture

What is post-truth? What are fake news? A pure pathology of information, or a phenomenon that reveals a different logic of social signification? Thanks to the tools of the semiotics of culture (in particular the semiotics of Umberto Eco and Juri Lotman), the text highlights how the criterion of truth of the discourses has radically changed (the “regime of truth”, as Foucault would say) and how a “confusive” regime has emerged that focuses on a criterion of authenticity based on experience, rather than a criterion of truth based on verification.
