We have not had to drag in any such spooks as mind, soul, or spirit. We have simply been talking of an interaction between physical vibrations and the brain with its various organs of sense, saying only that creatures with brains are an integral feature of the pattern which also includes the solid earth and the stars, and that without this integral feature (or pole of the current) the whole cosmos would be as unmanifested as a rainbow without droplets in the sky, or without an observer. Our resistance to this reasoning is psychological. It makes us feel insecure because it unsettles a familiar image of the world in which rocks, above all, are symbols of hard, unshakable reality, and the Eternal Rock a metaphor for God himself.
