Abstract
This introduction opens the monographic issue starting from 1968 and arriving to neoliberalism as its most articulated answer, without the claim to give a complete picture but in order to illuminate the complexity and radicality of this caesura. In this reconstruction 1968 starts well before, so that it is not possible to establish a precise starting date and place. The contestation of authority, the questioning of patriarchy, the activation of heterogeneous and often “unexpected” subjects: the fierce critique of the current state of things produced a crisis of legitimacy that involves the State, society, capitalism and science. In this sense 1968 was an unaccomplished and therefore never finished revolution.
