Abstract
The main goal of the paper is to determine who is the Dasein itself from the appearance of the world in the Book of Martin Heidegger Being and time (§§ 14-18). For this, it raises the possibility of understanding the horizon of the self of Dasein itself differently to Heidegger’s analysis about the they (§§ 25-27) and also it shows how the Selfhood of Dasein is presupposed already in the appearance of the world-environment through the existential meaningfulness. The conclusion of this paper will try to discover the phenomenological yields of Dasein’s openness as horizon of its Selfhood.
