ABSTRACTIn the Black Notebooks, Heidegger ascribes in 1938/9 to the Jewish race an “empty rationality and calculative ability,” in his view the cause of its “worldlessness.” To assess this characterisation, I present Heidegger’s theories of history as a decline in Being and Time and in his later history of Being. For this purpose, I discuss his notions of Rechnen, Machenschaft, and Geviert, several existentialia from Being and Time, and Heidegger’s identification of modern machination and modern technology. Furthermore, I examine Heidegger’s (...) attitude toward the Jews and the Holocaust. I present his alignment of the unconcealment of modernity and the Jewish race, and compare his theory of machination with the texts “Positionality” and “The Question concerning Technology”. Heidegger’s notes about the Jews in the Black Notebooks after 1944 confirm that he tried “to silence Auschwitz silently,” as I already argued in a paper from 1995. (shrink)
