In Being and Time, Heidegger nowhere treats the phenomenological reduction. In his Groundproblems of Phenomenology though, he designates reduction, construction and destruction as the three groundparts of phenomenological method. The whole of this method has thus to be seen as Heideggers alternative for Husserls reduction. But for a subject to be able to undertake this three-part methodological project, it has first to be converted from Husserlian ego to properly ‚Dasein‘. I show that the analytic of existentials of Being and Time can be seen as containing a rather precise description of the course of this conversion. It starts from originarity to end up with the subjects momentary participation in the project of being. It is structured by three turns that I call transcendental, not only because they are not initiated by the subject itself.
