" The world is filled half with evil and half with good. We can tilt it forward so that more good runs into our minds, or back, so that more runs into this.” A movement of her eyes took in all the lake. “But the quantities are the same, we change only their proportion here or there.” “I would tilt it as far back as I can, until at last the evil runs out altogether,” I said. “It might be the good that would run out. But I am like you; I would bend time backward if I could. "
