Recently Alan Gewirth has attempted to establish a universally valid foundation for ethics and politics by means of analyzing the “normative structure” of action and what that necessarily entails for any agent. By “normative structure”he means that by virtue of which certain “evaluative and deontic judgments on the part of agents are logically implicit in all action” (pp. 25–26). These judgments, leading finally to a supreme moral principle, are part of what is “conceptually necessary” to being an agent. Anyone who resists making these judgments is guilty of “selfcontradiction” and thus a diminution of his claim to be a rational being (pp. 44, 48).
Although Gewirth considers his approach to be a novel one, it infact exhibits some interesting parallels with the approach of the German philosopher andsocial-political theorist, Jiirgen Habermas. The latter has not written a systematic work on what he calls “communicative ethics,” but he has laid out its basic components. As with Gewirth, the foundation of this ethics lies in a certain “normative force” implicit in action. While there are such similarities of approach between the two theorists, they differ in the specific analyses they offer of action and of what constitutes an agent's claim to rationality.
