Who is Heidegger's Zarathustra? enquires into Heidegger's understanding of 'transcendence' from the perspective of his reading of Nietzsche. It shows how in Heidegger's Nietzsche interpretation, all the central themes of his phenomenological project come together - his analysis of Nihilism, the analytic of Dasein, 'the turning', the 'event of appropriation' (das Ereignis), the question of God and faith and the phenomenology of the 'I' (Ich-heit) or 'egoity' - not as a rupture from his earlier work but as a broadened, deepened and more nuanced attempt both to read Nietzsche and surpass him.
