"Show me one that isn't afraid!", said the brownshirt contemptuosly. "And it's so unnecessary. They just need to do what we tell them." 
"It's because people have got in the habit of thinking. They have the idea that thinking will help them." 
"They need to do as they're told. The Führer can do their thinking for them." 
[Alone in Berlin, Hans Fallada] 

Why still believe in the human race? Because, in the end, they realize thinking is all they have to do to be free.
