I'm fascinated by the period that goes from the Industrial Revolution to right after World War II. There's something about that period that's epic and tragic. There's a point after the industrial period where it seems like humanity's finally going to make it right. There were advances in medicine and technology and education. People are going to be able to live longer lives; literacy is starting to spread. It seemed like finally, after centuries of toiling and misery, that humanity was going to get to a better stage. And then what happens is precisely the contrary. Humanity betrays itself.
