Is there a God? Taner Edis has the answer to the big question, and he is qualified to submit an answer, given the amount of thinking he has done on it. A physicist, he has for years run the cerebral and entertaining e-mail Skeptic Discussion List...which is devoted to the discussion (read 'debunking') of such topics as astrology, psychic powers, creation 'science,' miracles, and more. So you can probably guess where he stands: There are thousands of gods you don't believe in, and chances are he believes in even fewer than you. In _The Ghost in the Universe: God in the Light of Modern Science_ (Prometheus Books), his first book, he tells why he thinks that a naturalistic view, based on science, is a better explanation for what we experience in the world than any reach for spiritual answers. It is clear, wide-ranging, and intelligent, and it brings in topics from philosophy and science explained at a level accessible to readers with no expertise in those fields. It perhaps will swing no one from the spiritual camp, but those who wish to stay within it with intellectual vigor will do well to examine the arguments here.
Edis starts with philosophical proofs of God: 'A perfect being must exist, since if it did not, it would not be perfect. Having made God pop into existence by sheer force of logic, we now break out the champagne.' They carry little weight, even among believers, who are more likely to favor stories of a God who created and maintains the universe. Even the argument that there has to be a first cause God is a strong one that withers under quantum physics. We are used, in day to day life, to examining causes and effects, but we are guilty of looking only in our own scale of neighborhood. In the quantum world, things happen without being caused, and the Big Bang was a quantum event; the chain back to the first cause is broken. Of course Evolution is covered, in only a chapter, which shows that Edis's book is about much more. Edis shows how the physics of the universe has a random foundation, and randomness can be harnessed to ratchet up to increasing complexities. No designer, intelligent or otherwise, is needed. He critiques the scriptures, including the Quran, as human creations. He shows that psychological and neurological evidence indicates that our brains are engaged in examining an unmagical world, and spirits, souls, or direct contact with some ultimate reality are all equally unlikely. He sees no transcendent moral reality, no good and evil 'out there'; morals instead are a product of our genes and our social, collective effort to live together and incorporate conflicting interests.
Believers should be grateful that they have such a gentle critic. It could only be a fundamentalist of insecure faith who would accuse Edis of trashing religion. In fact, in intelligent opposition, Edis has shown a great deal of respect for the religious view. He also reveals himself to be a fan of the stories religions tell, because they can explain a good deal about ourselves. Most will think that this will be giving the stories too little credit, but as he repeatedly says in acknowledging how little certainty we have, it is good enough. His book is certainly good enough to benefit believers and nonbelievers alike.
