Diskursetik by Jürgen Habermas

A procedural account of moral justification that grounds the validity of norms in the conditions of free, equal, and rational discourse rather than in outcomes or preexisting moral facts; it holds that a norm is binding only if those affected could accept it in a noncoercive exchange of reasons, elaborates a universalization procedure for testing norms, and locates ethical authority in communicative rationality and intersubjective agreement with implications for law, democracy, and practical reason.
