Once upon a time there were 12 people in a room. This room was very beautiful with large windows on every wall. Now it happened that 10 of the 12 people were blind which was sad because they could not experience the full beauty of the room. On this cloudless summer day deep in the South, as the sun climbed ever higher in the sky, the room grew brighter and brighter. The two people who were not blind said to the others, “We want to pull down the shades because the bright sun is hurting our eyes.” But the ten blind people said, “The sun is not hurting our eyes. We don’t understand what you mean. We don’t know what bright is.” And the blind people and the sighted people fought and it was sad.
