The weather bureau will tell you what next Tuesday will be like, and the Rand Corporation will tell you what the twenty-first century will be like. I don’t recommend that you turn to the writers of fiction for such information. It’s none of their business. All they’re trying to do is tell you what they’re like, and what you’re like—what’s going on—what the weather is now, today, this moment, the rain, the sunlight, look! Open your eyes; listen, listen. That is what the novelists say. But they don’t tell you what you will see and hear. All they can tell you is what they have seen and heard, in their time in this world, a third of it spent in sleep and dreaming, another third of it spent in telling lies.
