'Faye disputes the view of Heidegger as a naive, temporarily disoriented academician and instead shows him to have been a self-appointed 'spiritual guide' for Nazism whose intentionality was clear. Contrary to what some have written, Heidegger's Nazism became even more radical after 1935, as Faye demonstrates. He revisits Heidegger's masterwork, "Being and Time", and concludes that in it Heidegger does not present a philosophy of individual existence but rather a doctrine of radical self-sacrifice, where individualization is allowed only for the purpose of heroism in warfare.'
