The central claim of this article is that Habermas's program of discourse ethics fails to “detranscendentalize” the Enlightenment subject. On the contrary, tacit assumptions concerning a transcendental conception of reason and a subject that is teleologically predisposed toward its rightful end are the logical pillars of Habermas's two most crucial claims. First, unless Habermas presupposes an abstract and decidedly unencumbered moral discussant, he cannot maintain his claim concerning the rationality—and hence the unconditionality—of the moral principle he describes. Secondly, unless Habermas begs the question of the proper end of individual and collective development, he fails to support the claim that discourse ethics speaks to the emphatic dimension of moral reason.
