Jaspers' description of the nature and meaning of Weltorientierung occupies the entire first volume of Philosophie. In this chapter we will focus on three formal aspects of this analysis that are essential to obtaining an understanding of his overall method of "transcending-thinking." The first has to do with the phenomenon of "disjunction" (die Trennung) or being-in-the-world as an "indeterminate totality;" the second concerns the possibility of a "scientific world-view" in the light of this experience; and the third is a consideration of the "reversal" (die Umkehrung) in consciousness caused by a recognition of the limits of scientific inquiry and the conversion it can effect in the subject as the occasion for a movement into the language of interiority.
