A lot of people in prison like to read books. Adolf Hitler likes to write books. So he writes Mein Kampf, which is really the blueprint for the Nazis for the Third Reich, which is what his future entails. And in Mein Kampf, that blueprint for the Third Reich, he's really outlining a few big ideas. One is that there is a distinction in race, that there are some people that are better than other people. And he calls those people Aryans. So if you were blonde hair and blue eyed, you're the perfect German Aryan, and you are the master race, and you really, in a sense, it's like social Darwinism.
