I've always thought fairies are like mushrooms, you trip over them when you're not thinking about them, but they're hard to spot when you're searching for them.
Jo WaltonIf the purpose of literature is to illuminate human nature, the purpose of fantastic literature is to do that from a wider perspective. You can say different things about what it means to be human if you can contrast that to what it means to be a robot, or an alien, or an elf.
