ABSTRACT
Habermas’s study of discourse ethics is presented in a series of sharply detached arguments. In devising a just procedure, one must presuppose an ideal situation of symmetric reciprocity. In the case of sociopolitical norms and rules, “to be concerned” does not simply mean “to be influenced by,” but also “to be subjected to.” The fundamental principle of universalization is about testing all social or political norms and rules. The fundamental principle of universalization is thus the principle of sociopolitical legislation. Habermas formulated the fundamental principle of universalization with a view to the practicing of a discourse ethics, for the principle can only be observed by conducting a rational discourse. Although moral norms cannot be grounded in a universalistic procedure, sociopolitical norms (laws) of justice can be. Despite its theoretical shortcomings, Habermas’s discourse ethics conveys a message of the utmost importance.
