§The second principle was demonstrated by watching beavers repairing their dam, which had been damaged by a flood. Each beaver swam back and forth with branches, and anchored them to the dam. There is no boss beaver telling the other beavers what size of branch to bring or where to put it. Each beaver decides for itself how it will contribute to getting the dam repaired. If they want to work at one end, fine. If they want to bring small branches, great. They exercise their own best judgment.
