Über die unüberwundenen Begründungsdefizite der „Kritischen Theorie“ – Von Habermas zu Forst

In the first part of this paper I argue that there is hardly one correct step within the chains of arguments by which Habermas tries to substantiate his theory of communicative action, discourse ethics, and his theory of social order. In the second part of the paper I address Rainer Forst’s “principle of justification,” from which he seeks to deduce his ‘right to justification’ on which a “right to justification” is supposed to be based. I argue that Forst himself does not really justify his views but instead offersmerely unwarranted stipulations.Moreover, I demonstrate that his theory is unclear, incoherent, inapplicable, and thus practically irrelevant.
