Heidegger became probably the foremost intellectual in the world to back the Nazi Party. Arendt went on to write a book called The Origins of Totalitarianism, in which she discusses the rise of Nazism at some length, and talks about Nazi theorists such as Carl Schmitt.
There is no index entry for "Heidegger."
Is this cowardice? Or is it prudent, as any negative comments about Heidegger could be seen as personally biased?
UPDATE: A reader notes her PhD was actually supervised by Karl Jaspers.
