That Heidegger sees western metaphysics to end with Nietzsche is basically just saying that after Nietzsche, to turn back to metaphysics, while obviously possible, is too uninteresting to bear the name of philosophy anymore. This 'end of philosophy' is not the 'death of values' or the unwritten rules regulating behaviour and belief more than ever (Zizek). It is precisely being caught in this mutual end between affirming that something and denying it in order to submitt it under another conceptual edifice- which begins the entire metaphysical constellation of dialectics in a new way. But this is philosophy, Heidegger tells us, philosophy cannot offer anything more. In this sense he wishes to stand outside philosophy and metaphysics as did Derrida.
