...The spirit is in charge to tell the individual that he can so organize his body that he is now in line with a supporting force. He cannot just go on indefinitely striking out indiscriminately against this force that's tearing him down, yet this is what her tries to do. You know average posture: the head way forward, the back way back, the chest almost lacking, the ribs down, no air coming in etc., etc. His sprit will carry him through? It is an assumption that no longer works; it is the relic of an idea which was universal a hundred years ago.
