Paolo Virno (/ˈvɜːrnoʊ/; Italian: [ˈvirno]; born 1952) is an Italian philosopher, semiologist and a figurehead for the Italian Marxist movement. Implicated in belonging to illegal social movements during the 1960s and 1970s, Virno was arrested and jailed in 1979, accused of belonging to the Red Brigades. He spent several years in prison before finally being acquitted, after which he organized the publication (Italian for "commonplace") in order to vocalize the political ideas he developed during his imprisonment. Virno currently teaches philosophy at the University of Rome.
