In this essay Walter Okshevsky addresses the question of whether a certain form of dialogically derived agreement can function as an epistemic (universal and necessary) criterion of moral judgment and ground of moral authority. Okshevsky examines arguments for and against in the literature of educational philosophy and develops Jürgen Habermas's affirmative answer as presented in his discourse theory of morality. Habermas's position is articulated as a moral epistemology (“strong dialogicality”) and is developed through his critique of the “monologism” of certain aspects of Immanuel Kant's moral theory. Okshevsky concludes with a consideration of some educational implications of Habermas's position.
