This chapter develops a model of the relationship between revolution and person with detailed reference to the life and family histories collected in Havana in the late 1960s by the American anthropologists Oscar and Ruth Lewis and the team of researchers they trained in Cuba. The focus here is on ethnographic material from the Lewis’ volumes pertaining to people’s revolutionary ‘integration’ through participation in state-coordinated mass organizations, and particularly the so-called Committees for the Defence of the Revolution (CDRs). Tracking ethnographically the ways and degrees to which the Lewis’ respondents got involved in these neighbourhood level structures, the chapter develops a model of revolutionary personhood that emphasises the duality between ‘role’ and ‘person’. Due to the totalizing way it ensconces itself in every aspect of everyday life, this duality marks out the coordinates for people’s continual acts of comparison and calibration between the two, which becomes the prime format of daily social life in revolutionary Cuba. By the same token, the duality of role and person marks out the limits of the revolution’s transcendentalizing project, whose containing force reaches only as far as its designation of roles via the state’s structures can take it, leaving the remainders of people beyond its scope.
