The idea was to have a basin inverted on his head and his hair cut to the shape of it. Skill and money were not needed. Then the idea grew that it was more convenient to leave the basin on his head. Stray thoughts were trimmed along with stray hair; brain-vines, tentacles of thought, were not encouraged to wander. Then, in the interests of human economy, the head of adaptable man became a basin of uniform shape—a basin, a crash helmet. Safe at last; no more thought-cuts.
