"There were a lot of utopias in the nineteenth century, wonderful societies that we might possibly construct. Those went pretty much out of fashion after World War I. And almost immediately one of the utopias that people were trying to construct, namely the Soviet Union, threw out a writer called Zamyatin who wrote a seminal book called We, which contains the seeds of Orwell and Huxley. Writers started doing dystopias after we saw the effects of trying to build utopias that required, unfortunately, the elimination of a lot of people before you could get to the perfect point, which never arrived. … I don’t believe in a perfect world. I don’t believe it’s achievable, and I believe the people who try to achieve it usually end up turning it into something like Cambodia or something very similar because purity tests set in. Are you ideologically pure enough to be allowed to live? Well, it turns out that very few people are, so you end up with a big powerful struggle and a mass killing scene."
