Writing in one of Mussolini’s prisons in the 1930s, the Italian Marxist Antonio Gramsci jotted down the fragments that would become his theory of intellectuals. New classes, like the European bourgeoisie after the Industrial Revolution, he proposed, brought with them their own set of thinkers, which he called “organic intellectuals”—theorists, technicians, and administrators, who became their “functionaries” in a new society. Unlike “traditional intellectuals” who held positions in the old class structure, organic intellectuals helped the bourgeoisie establish its ideas as the invisible, unquestioned conventional wisdom circulating in social institutions.
