"It is... Jung's finding that men who try to live without contact with the unconscious and its symbolic and mythological meaning often fall sick both psychologically and physically. ...Until Jung could help them find contact with their unconscious roots, from which the rational materialism of today had cut them off, they could not get well. ...the real business of religion, as Jung maintained, is to keep men in touch with this level of reality, and this is done largely through the use of myths."
