"Most civilization is based on cowardice. It's so easy to civilize by teaching cowardice. You water down the standards which would lead to bravery. You restrain the will. You regulate the appetites. You fence in the horizons. You make a law for every movement. You deny the existence of chaos. You teach even the children to breathe slowly. You tame."
