The Necronautical Society 
interviews Simon Critchley:
Heidegger's work is all about time: for him, time is the horizon of being, and time is facilitated by death - decay and death is what makes time possible. And there's an emphasis on travel - which is something that interests this organisation, the INS, as well. Heidegger has this expression Holzwege - and didn't he actually compose his work as he strode in manly fashion through these black German forests? 
SC: So he would like us to believe. 
TMcC: Is it not true, then? 
SC: Oh, he walked a lot. He was a great walker.
Time for another walk, then. Forests are black here too. Leastways now, at night.
