"While the critique of the intellect answers the question how the consciousness of the unconscious society is constituted, the critique of economics explains how the life process of the unconscious society can succeed." "One can even go further and say that all systematic philosophy, which stands under a norm of timeless absolute truth, consciously or unconsciously amounts to an apology of social class distinction, because categories of thought which claim timeless validity can never be derivable from the elements of manual labor, since these are spatiotemporal in nature. Only a theory of scientific knowledge, which stands under a norm of time-bound truth, is able to serve the eventual historical unity of manual and mental work. Such a theory must be dialectical, because the logic of time-bound truth is nothing else.
