“He was split, one part of him never left this mental chamber that pictured itself as a sphere full of light fading into dark, because there was no way out. But motion in this world depended on rest in the world outside. A man is in bed, wanting to sleep. A rat is behind the wall at his head, wanting to move. The man hears the rat fidget and cannot sleep, the rat hears the man fidget and dares not move. They are both unhappy, one fidgeting and the other waiting, or both happy, the rat moving and the man sleeping.”
