"On the planet O there has not been a war for five thousand years," she read, "and on Gethen there has never been a war." She stopped reading, to rest her eyes and because she was trying to train herself to read slowly, not gobble words down in chunks the way Tikuli gulped his food. "There has never been a war:" in her mind the words stood clear and bright, surrounded by and sinking into an infinite, dark, soft incredulity. What would that world be, a world without war? It would be the real world. Peace was the true life, the life of working and learning and bringing up children to work and learn. War, which devoured work, learning, and children, was the denial of reality. But my people, she thought, know only how to deny. Born in the dark shadow of power misused, we set peace outside our world, a guiding and unattainable light. All we know how to do is fight. Any peace one of us can make in our life is only a denial that the war is going on, a shadow of the shadow, a doubled unbelief.
