In opposition to the project summarized in the Theses on Feuerbach (the realization of philosophy in praxis which supersedes the opposition between idealism and materialism), the spectacle simultaneously preserves, and imposes within the pseudo-concrete of its universe, the ideological characteristics of materialism and idealism. The contemplative side of the old materialism which conceives the world as representation and not as activity–and which ultimately idealizes matter–is fulfilled in the spectacle, where concrete things are automatically the masters of social life. Reciprocally, the dreamed activity of idealism is equally fulfilled in the spectacle, through the technical mediation of signs and signals-which ultimately materialize an abstract ideal.
