Dasein’s Shadow and the Moment of its Disappearance

In his 1937 lectures, Heidegger searches for Nietzsche’s initial thought of “the Moment”. This paper mimics Heidegger’s pursuit of Nietzsche’s Moment by tracing Heidegger’s own early arrival at the Moment in Being and Time, published 10 years prior to his lectures on Nietzsche. Both Zarathustra and Dasein are chased in and out of an authentic relationship with the Moment by their own shadows, which disappear at midday. Dasein’s shadow is the being that is always closest-at-hand, the being in whom I lose myself in everyday care. Dasein forgets itself in inauthentically securing its identity in that which it cares for and that which it is not, darkness. Yet Dasein also confronts its own finitude in its negative double as it witnesses the daily dwindling of its shadow—the everyday passing away of time.
