"'I studied philosophy in university and I always found it 
  rather impotent. This is different. This is principle driven. 
  It's practical. You can do something with it' [...] being 
  definite, principle centered, and practical are not always 
  good things. The Nazis were all of those things, more so than 
  most people."
                 --Mark Kingwell, "In Pursuit of Happiness"
