"Oh, I read good books, too, but only Earthside. Why that is, I don't really know. Never stopped to analyze it. Good books tell the truth, even when they're about things that never have been and never will be. They're truthful in a different way. When they talk about outer space, they make you feel the silence, so unlike the Earthly kind — and the lifelessness. Whatever the adventures, the message is always the same: humans will never feel at home out there."
