Google translate gives me gibberish, but with the possible exception (I can't tell) of comments at the end of both blurbs the gibberish seemed to be downplaying the elephant in the dining room. My German is inexcusably (for someone who lived there for two years as a child) awful, so I'd be really interested to see how the blurb accords with the Derbyshire piece.
In particular a couple of things seem clear to me:
- Contra Faye et. al.'s repeated claims, the substance of Heidegger's pre and early 30's philosophy has absolutely nothing to do with anti-semitism or Nazism,
- The fact that Heidegger was not a "crude biological racist" is a dangerous non-sequitur (neither were most Nazi's, who had a metaphysical conception of race rooted in German Romanticism),
- Heidegger's middle and late work is tainted by the Nazism just to the extent that the history of being (especially the way it is tied to views of the German language and people and their relation to the Greeks) recapitulates central German Romantic themes that actually were central to blood-and-soil Nazism, and
- It's possible that the most interesting thing about the black notebooks is that they make this connection much clearer.
Now, 3 and 4 may be completely wrong, or may be the kind of things that informed people of good will can disagree about*. But if the blurbs are written in a way that forecloses 3 and 4, this seems a little bit problematic to me.
