In this article, I argue for an historical understanding of the relationship between ideology and utopia/utopianism that positions the latter as a specifically modern compensation for the loss of the cosmologically grounded, unitary ideology supplied by the late medieval Christian Church. This claim relies upon but revises Fredric Jameson’s early theorization of the collaboration between ideology and utopia/utopianism, which emphasizes that utopian elements allow ideology to offer subjects a ‘compensatory exchange’ for their complicity. Developing my central argument requires considering the (...) current viability of the ‘secularization thesis’, which classically associated modernization with secularization but which has undergone heavy criticism and revision by social scientists over the past half-century. These theoretical discussions, finally, are couched within a critical appraisal of the status of utopianism in contemporary politics. (shrink)
