Authenticity (Eigentlichkeit) plays a foundational role in early Heidegger. To “work out the question of Being adequately”, Heidegger states, “we must make an entity—the inquirer—transparent in his own Being” (BT 27/7; similarly, BP 103). Authenticity is central to such transparency: if our understanding of Dasein is to serve as “a foundation for the basic question of ontology, then it must first have been brought to light . . . in its possibilities of authenticity and totality” (BT 276/233). Authenticity, in other words, underpins the ontological project. The aim of this chapter is to better understand what authenticity is and why it matters so much to Heidegger.
