Heidegger's career was already established.Some us need money, in addition to the kudos - two kids to get through college, and all that. If Cohen had actually read the book, instead of limiting himself to the NY Times review, he would have known that, after the chair of philosophy four years earlier, being elected Rector of Freiburg was just the next step in Heidegger's career plan. In any case, it's nice of him to bring up the comparison with von Braun and von Karajan, as that covers both the practical sciences and arts. I'll stick with Heisenberg for my comparisons; if only for the prosody. Read the whole article for its banal prose and metaphors; "they were no different than a goon and his gal".
