Introduction to Habermas's Discourse Ethics
Habermas situates the moral point of view within the communication framework of a community of selves. He moves Kant's categorical imperative beyond its 'monological' reflection by demanding that we emphatically take into consideration the viewpoints of all who would be affected by the adoption of a certain moral action or normative claim. In a similar vein, he 'lifts' Rawls' veil of ignorance and demands that we participate in a discourse where all are fully aware of the other's perspectives and interpretations.
This move toward a 'dialogical form of practical reason' is incumbent upon 'post modern societies' where an irreducible plurality of 'goods' conditions and limits the horizon for moral conversation. Morality comes to represent duties and obligations within a just society -- a society in which 'rights' trump competing 'goods' in circumstances of conflict. (r.c.)
