"Science fiction is a literature that explores the fact that human beings are part of social systems and that social systems change. It explores social change and the human change that both drives it and is affected by it. Fantasy, which I write more than I write science fiction, is a literature that explores the stories we tell to explain the inexplicable. It also explores human nature. Fantasy pays homage to folklore and folklore talks a lot about archetypes. Fantasy explores those archetypes and also explores the way we tell stories to explain things like why there’s a moon in the sky or things that we have no explanation for, but we believe. Fantasy explores what we believe."
