@ayjay When I was studying Heidegger in the 1980s it seemed the older generation all knew full well he was a lifelong Nazi, but somehow he'd been given a free pass for being 'important'. I never really understood that. His former student (and Hannah Arendt's first husband) Günther Anders was calling him out at least as early as 1948. Yet somehow, in spite of everything, it has continued to be a slow-motion surprise. Your review (and Wolin's book, of course) goes some of the way towards showing why that might be.
