We have to revalue “determination” towards the setting of limits and the exertion of pressure, and away from a predicted, prefigured and controlled content. We have to revalue “superstructure” towards a related range of cultural practices, and away from a reflected, reproduced or specifically dependent content. And, crucially, we have to revalue “the base” away from the notion of a fixed economic or technological abstraction, and towards the specific activities of men in real social and economic relationships, containing fundamental contradictions and variations and therefore always in a state of dynamic process. (1980: 34)
