Does Hegel's Critique of Kant's Moral Theory Apply to Discourse Ethics?

Abstract

Several years ago Jürgen Habermas wrote a short answer to the question: “Does Hegel's Critique of Kant apply to Discourse Ethics?” The gist of his short answer is, “no”. Insofar as Hegel's criticisms of the formalism and abstract universalism of the moral law never even applied to Kant's moral theory in the first place, they also fail to apply to discourse ethics. Insofar as Hegel's criticisms of the rigorism of the moral law and of Kant's conception of autonomy do hit the mark, discourse ethics successfully draws their sting by reconceiving Kant's moral standpoint along the following lines. 1. Kant wrongly undertakes to establish the moral law as a “fact of reason”: discourse ethics derives the moral standpoint from two premises — one formal, a rationally reconstructed logic of argumentation, and one material, namely our intuitions about how to justify utterances. 2. Kant wrongly contends that we must be able to think of ourselves as both intelligible characters, inhabiting a noumenal world, and as empirical characters inhabiting the world of appearances: discourse ethics allows that in everyday contexts of action and in the context of moral discourse we have one character that has real needs and interests. 3. Kant is also mistaken in arguing that moral autonomy requires human beings to abstract away from their needs and interests and to will universalizable maxims for the sake of their universal form: discourse ethics understands moral autonomy to consist in the free adoption of a standpoint from which conflicts of interest can be impartially regulated, by giving special weight to the satisfaction of universalizable interests. 4. Kant misconceives the categorical imperative as an objective test of universalizability that is applied by individual wills in isolation: discourse ethics reconceives the moral universalism as an ideal of intersubjective agreement of participants in discourse. On the differences between the principles of discourse ethics and Kant's categorical imperative Habermas is wont to cite McCarthy's summary of his — Habermas' — position: “Rather than ascribing as valid to all others any maxim that I can will to be a universal law, I must submit my maxim to all others for the purposes of discursively testing its claim to universality. The emphasis shifts from what each can will without contradiction to be a general law, to what all can will in agreement to be a universal norm” (MCCA 67).
