The author distinguishes two concepts of practical reason: (a) practical reason as a source of practical principles, and (b) practical reason as the theory of thought operations connected with action. He proves that there is no practical recognition in the sense (a). We can deal with actions only on the basis of dichotomic semantics. Critical analyses of some theories of practical reason are presented (Kant, Lorenzen, Apel, Alexy). The critical part of the paper mainly concerns the discourse theory and its (...) implications for practical philosophy and jurisprudence. (shrink)

In this paper the author criticizes the way Robert Alexy reconstructs the relationship between legal and practical reasoning. The core of Alexy's argumentation (Alexy 1978) is considered the claim that legal argumentation is a “special case” of general practical discourse. In order to question this claim, the author analyzes three different types of argument: (1) that legal reasoning is needed by general practical discourse itself, (2) that there are similarities between legal argumentation and general practical discourse, (3) that there is (...) a correspondence between certain types of argument in general practical discourse and in legal argumentation.**.

According to the author there is no doubt that one has to distinguish between the justification and the application of norms. Problems are seen only to arise if one asks what exactly the distinction is and which consequences have to be drawn from it. Recently, Klaus Günther, in particular, has searched for this distinction and connected it with far‐reaching conclusions concerning the theory of norms, arguments, and morals. His theses are the object of the author's considerations.
