On Heidegger's Concept of "Dasein" – A Discussion Based on Being and Time

Abstract

"Dasein" is a central concept in Heidegger's philosophy, representing a unique form of existence among many. Unlike other existents, it takes priority over them, defining their existence. Unlike other theories of existence, the ontological treatment of "Dasein" is not an abstract idea but deeply rooted in everyday human life. This paper explores the concept of "Dasein" following the insights of Being and Time. This passage discusses the background and significance of Martin Heidegger's philosophy, as well as its research value and influence on subsequent philosophers. It then delves into Heidegger's philosophy of "Dasein," explaining its fundamental constructs, including the rejection of the Cartesian subject and the establishment of a solid philosophical foundation based on existence itself rather than the level of the existent. It further explores the basic ways in which Dasein unfolds, such as "thrownness," "projection," and "fallenness," deepening the understanding of the structure of being-in-the-world and its fundamental regulations.
