"Many beings live lives of quiet correctness without ever being once making anything do anything. Things around them just happen to be orderly. The social system props them up.
"But someday--bang--the society gets into a turmoil which knocks out the props.
"Then we see that there were too few present who could make things go right and that is the end of the society.
"Thus died old civilizations." --L. Ron Hubbard
