Philosophy in Search of an Ethics of Universal Dialogue
Throughout human history, both lying and the coercion of someone's belief and will have been rejected through prohibitions that are a precondition for mutual understanding between people as well as for any agreement. Immanuel Kant contributed to the ethical formulation of these prohibitions, proving these universal claims through his method of transcendental formalism. Kant's theory of the categorical imperative is fruitfully developed by the ethics of discourse as the theory of the ultimate moral ground of earnest argumentation and consensus. I examine the post-metaphysical transformation of the categorical imperative, as expressed in the works of Karl-Otto Apel and Jürgen Habermas. Discourse ethics confronts the hermeneutical contextualist critique of universalism. This ethics develops a transcendental-pragmatic foundation for a universally valid principle of coresponsibility. It contributes to the search for a rationally grounded normative base for universal dialogue.
