  Heidegger's involvement with Nazism casts a shadow over his life. Whether, and if so to what extent, it casts a more concentrated shadow over at least some of his philosophical work is a more difficult issue. It would be irresponsible to ignore the relationship between Heidegger's philosophy and his politics. But it is surely possible to be critically engaged in a deep and intellectually stimulating way with his sustained investigation into Being, to find much of value in his capacity to think deeply about human life, to struggle fruitfully with what he says about our loss of dwelling, and to appreciate his massive and still unfolding contribution to thought and to thinking, without looking for evidence of Nazism in every twist and turn of the philosophical path he lays down.
