The Earth is beautiful, and bright, and kindly, but that is not all. The Earth is also terrible, and dark, and cruel. The rabbit shrieks dying in the green meadows. The mountains clench their great hands full of hidden fire. There are sharks in the sea, and there is cruelty in men's eyes.
Ursula K. Le GuinScience fiction is not predictive; it is descriptive.... Prediction is the business of prophets, clairvoyants, and futurologists. It is not the business of novelists. A novelist's business is lying.... 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.
Ursula K. Le GuinThe trouble is that we have a bad habit, encouraged by pedants and sophisticates, of considering happiness as something rather stupid. Only pain is intellectual, only evil interesting. This is the treason of the artist: a refusal to admit the banality of evil and the terrible boredom of pain.
