“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 Guin, The Tombs of Atuan

“I don't care that they stole my idea . . I care that they don't have any of their own”
