She accepts the Marxian critique of the dominant, capitalist ideology,and the academic theories which refine and develop it.For these theories,the key concepts are abstract categories of exchange, and they are rooted in experience of market relations. However, the experience of male wage-workers under capitalism provides a basis for a different and rival understanding of reality, both social and natural. this derives from workers's direct participation in the more fundamental level of social activity-the production of the commodities exchanged in the market. this productive activity avoids the abstraction of mental labour,uniting mental and manual aspects of practice,engaging with the natural world, and being alive to qualitive differences( as against the capitalists merely quantitative concern with money and profit )
