The still subversive and utopian contents in the relations of people to people and nature, which are not past because they were never quite attained, can only be of use in this way. These contents are, as it were, the goldbearing gravel in the course of previous labor processes and their superstructures in the form of works. Polyphonous dialectics, as a dialectics of the "contradictions" which are more concentrated today than ever, has in any case enough questions and contents in capitalism that are not yet "superseded by the course of economic development".
