Interstitiality: towards a post-althusserian theory of transition

The aim of this paper is to give some insights in order to make the theoretical construction of the concept of interstitiality possible in Marxist theory. For this reason, it is worth to examine how, after reflecting on the crisis of Marxism in the late 1970s, and after being confronted with the failure of social projects directed by the state, Louis Althusser elaborates the elements for an “aleatory” conception of historical passages which goes beyond any deterministic and teleological model of transition, to think the passage beyond capitalism not as transcendence, nor as development of “innate” potential, but as an “activation” of elements of an ontology of the present.
