At work the other day a coworker noted the anniversary of Origin of Species – 150 years.  This coworker seemed interested or positive about the mention and so I took the opportunity to instruct that the book was the philosophical basis for the Holocaust.  The coworker looked at me quizzically and I explained that if people were nothing except developed animals, there was no difference killing a person, than butchering beef or killing an animal which was not wanted.  Therefore, philosophically speaking, that book was the basis of the Holocaust.
