This article explores Adorno’s negative dialectics as a critical social theory of economic objectivity. It rejects the conventional view that Adorno does not offer a critique of the economic forms of capitalist society. The article holds that negative dialectics is a dialectics of the social world in the form of the economic object, one that is governed by the movement of economic quantities, that is, real economic abstractions. Negative dialectics refuses to accept the constituted economic categories as categories of economic nature. Instead, the article argues, it amounts to a conceptualized social praxis [begriffene Praxis] of the capitalistically constituted social relations, which manifest themselves in the form of seemingly independent economic categories. Economic nature is a socially constituted nature, which entails the class antagonism in its concept. The article concludes that for negative dialectics the explanation of real economic abstractions lies in the understanding of the class-divided nature of human practice.
