Religions have always been in the business of meme generation, offering narratives that orient and inform the course of existence. Such stories have traditionally described the dilemmas experienced and the moral and spiritual decisions reached by particular persons -Moses, Muhammad, The Buddha, Jesus- persons with whom we identify and whose faith decisions we try to emulate. Such stories are, of course, to be cherished. They link us with our heritage, they speak deep psychological truths, and they are sacred to those who orient their lives within the eminence of God. But, in addition, a new naturalism would strive to articulate metaphors from nature, metaphors that have a universality, a global meaning that transcends particular cultures and faith traditions.
