Abstract

The so-called structuralistic view of theory-formation is applied to the discourse-theory of normative validity in order to shed some light on the relation between the core and some basic application of discourse ethics. First, metatheoretical notions as core, model and intended paradigmatic applications will be introduced. Second, the two supreme principles of discourse ethics will be justified and a basic model will be explained. Two possibilities to define the very core of this ethical theory will be distinguished. In the following section, special attention is given to three paradigmatic applications of the theory. It is argued for the moral validity of some basic norms of action including several types of moral and legal rights. The article ends up with a discussion on conceptual modifications which are due to the enlargement of the scope of discourse ethics and with some brief remarks on the state of discourse ethics being a comprehensive ethical theory
