Abstract
This paper seeks to understand Heidegger’s phenomenological analysis of the time experience in Sein und Zeit, from the formal point of view of the Care-structure, and in the Seminars of Zollikon, where time is described as world-time in its fullness. Aimed is to show that the early anthropological reception of his major work of 1927 by some of his pupils, like Löwith, who detected similarities with Psychoanalysis, is somehow strengthed by Heidegger himself later on, as he comes with Medard Boss to develop Daseynsanalysis as a metaonlogical understanding of humans life in health and pathology. Illness as privation of health will be seen as the failure of inauthentic existence. And the full, ecstatical experience of time will be shown as the proper or authentic one, being-in-the-world as well as within the psychoanalytical session and interpretation.
