Vernunft heute

What type of reason will work in the present conditions? To answer this question, a meaningful concept of reason (as distinct from rationality) has to be developed, and its contemporary prerequisites (due to changes in the field of rationality) have to be specified. In part I. of the paper, the radically altered structure of rationality is analysed; it turns out to be characterized by rational disorder. Part II. offers a redefinition of reason; guided by the idea of justice, reason operates in transition from one rationality to another. This new kind of reason - "transversal reason" - is further elaborated in part III. It is regarded as a key-element of any type of reason.
