Abstract

The ongoing discussion about a notion of pragmatic rationality has evolved in a variety of different approaches, mainly because every author tries to combine his genuine philosophical point of view with the interpretation of “rationality”. Nevertheless there is an agreement of sorts that rationality cannot proceed mereley descriptively but has also normative implications.The paper investigates the proposals of Nicholas Rescher and Herbert Schnädelbach concerning the question of a normativity of rationality. Moreover it deals with the problem of “unity of reason” and its interconnectedness with the inherent normativity of rationality.
