Sonia Sikka's Heidegger, Morality and Politics: Questioning the Shepherd of Being
One thing Heidegger never disowned is the way he tied authentic Dasein to rootedness in the history of a people and in a particular region. Sikka does a fine job of illuminating the way many of Heidegger's thoughts here were prefigured by romantic thinkers, especially, Herder, the later Fichte, Schleiermacher, and Müller.
So much for the first beginning, and it all having gone off-kilter in Plato's day. Is Herder a product of metaphysics, or is Herder's nationalism an originary understanding of being?
