Mahon O’Brien's Heidegger, History and the Holocaust
Heidegger’s concept of Gelassenheit is born out of his attempts to come to terms with what went wrong during the National Socialist regime in Germany. This concept is also born out of Heidegger attempts to confront the technological view of the meaning of being, and so offers us a potential way out of the force of its Gestell. O’Brien points out, however, that even as late as the 1950s this concept is entrenched in Heidegger’s idea of the ‘authentic rootedness of the people’.
