This thesis is a study of the role of the phenomenon of death in Heidegger’s philosophy. The central argument is twofold. First, death is the fulcrum of Heidegger’s philosophy. As such, second, death is a crucial key to Heidegger’s thought in its entirety. Thus I claim is that a response to the question of being can be given, if one takes death into account. This thesis, therefore, investigates the four main blocks of Heidegger’s philosophy and the role of death in them. I identify the four main blocks of Heidegger’s philosophy as follows. First, Heidegger’s early transcendental analysis of Dasein’s existence. Second, the thinking of being as event. Third, Heidegger’s critique of technology. Fourth, Heidegger’s engagement with language. The thesis is divided into four topical parts according to these blocks. In the first part I argue that death serves as Dasein’s utmost limit and as such death is constitutive of Dasein’s existential possibilities. The analysis of Dasein’s horizons of understanding is what leads Heidegger to turn to being itself. In the second part I identify the place of death in the thinking of the event and in Heidegger’s theory of history as the history of being. I argue that death becomes an interest of being as such and is testimony to its epochs. Third, I argue that death continues to play a significant role in Heidegger’s philosophy of technology. This is because the essence of technology is a mode of being itself in the sense that being allows for a certain understanding of the current technological age. Thus, technology is an interest of being itself, too, and the essence of technology is sheer availability. Heidegger begins to call death the refuge of being at this time, which indicates that death is as the utterly unavailable, the resting place of being. As such, I argue in parts III and IV, death coenables the fourfold, which is Heidegger’s response to the technological world. In the fourfold things are not manipulated but form the bedrock of a shared communal world. In part IV I develop Heidegger’s claim that there is an essential relation between death and language. In the information age language is reduced to a transmitter of information. Thanks to its relation with death as the utterly unavailable language retains other dimensions that elude the demands of technology.
