Abstract
For Max Weber it was still a matter of course to understand the process of rationalization in occidental history as an outcrop of our modern world; and the classical writers of social theory have described the new reflective treatment of tradition and the differentiation of the spheres of life more exactly. In the fifties the “modernization” of societies was presented with neutral detachment, and Arnold Gehlen was able to maintain that rationalization in our “post-history” was proceeding in crystallized forms, but was no longer able to make a creative critical appraisal of its own underlying suppositions. Subversive criticism tried to unmask reason as the will to power and was thus able to proclaim the post-modern age. It is the complicity between these conservative and anarchic forces that Habermas is here opposing, taking the project of modernity as something incomplete that is still waiting for completion.
