In The Globe and Mail, Mark Kingwell on separating the man from his work.

What a world-class creep! And still I recommend that my students read Heidegger. Why? Because the man is the instrument, not the hand. I assign his work in almost every class I teach, because his insight is indisputable. I never play down the Nazi proclivities, or how they are joined to deeper thoughts about Earth and world, beauty and truth. He was a terrible man, but a great philosopher.
