This fall, evolutionary biologist and best-selling author Richard Dawkins -- most recently famous for his public exhortation to atheism, 'The God Delusion' -- returns to writing about science. Dawkins' new book, 'The Greatest Show on Earth,' will inform and regale us with the stunning 'evidence for evolution,' as the subtitle says. It surely will be an impressive display, as Dawkins excels at making the case for evolution. But it's also fair to ask: Who in the United States will read Dawkins' new book (or ones like it) and have any sort of epiphany, or change his or her mind? Surely not those who need it most: America's anti-evolutionists. These religious adherents often view science itself as an assault on their faith and doggedly refuse to accept evolution because they fear it so denies God that it will lead them, and their children, straight into a world of moral depravity and meaninglessness. An in-your-face atheist touting evolution, like Dawkins, is probably the last messenger they'll heed. Dawkins will, however, be championed by many scientists, especially the most secular -- those who were galvanized by 'The God Delusion' and inspired by it to take a newly confrontational approach toward America's religious majority. They will help ensure Dawkins another literary success. It's certainly valuable to have the case for evolution articulated prominently and often, but what this unending polarization around evolution and religion does for the standing of science in the U.S. is a different matter entirely. It often appears as though Dawkins and his followers -- often dubbed the New Atheists, although some object to the term -- want to change the country's science community in a lasting way. They would have scientists and defenders of reason be far more confrontational and blunt: No more coddling the faithful, no tolerating nonscientific beliefs. Scientific institutions, in their view, ought to stop putting out politic PR about science and religion being compatible. The New Atheists win the battle easily on the Internet. Their most prominent blogger, the University of Minnesota biologist P.Z. Myers, runs what is probably the Web's most popular science blog, Pharyngula, where he and his readers attack and belittle religious believers, sometimes using highly abrasive language. More moderate scientists, however -- let us call them the accommodationists -- still dominate the hallowed institutions of American science. Personally, these scientists may be atheists, agnostics or believers; whatever their views on the relationship between science and religion, politically, spiritually and practically they see no need to fight over it. Thus the American Association for the Advancement of Science and the National Academy of Sciences take the stance that science and religion can be perfectly compatible -- and are regularly blasted for it by the New Atheists. Or as the National Academy of Sciences put it in a recent volume on evolution and creationism: 'Today, many religious denominations accept that biological evolution has produced the diversity of living things over billions of years of Earth's history. ... Religious denominations that do not accept the occurrence of evolution tend to be those that believe in strictly literal interpretations of religious texts.' A smaller but highly regarded nonprofit organization called the National Center for Science Education has drawn at least as much of the New Atheists' ire, however. Based in Oakland, Calif., the center is the leading organization that promotes and defends the teaching of evolution in schools. In this endeavor, it has, of necessity, made frequent alliances with religious believers who also support the teaching of evolution, seeking to forge a coalition capable of beating back the advances of fundamentalists who want to weaken textbooks or science standards. In the famous 2005 Dover, Pa., evolution trial, for instance, the NCSE contributed scientific advice to a legal team that put a theologian and a Catholic biologist on the stand. Long under fire from the religious right, the NCSE now must protect its other flank from the New Atheist wing of science. The atheist biologist Jerry Coyne of the University of Chicago, for instance, has drawn much attention by assaulting the center's Faith Project, which seeks to spread awareness that between creationism on the one hand and the new atheism on the other lie many more moderate positions. In this, Coyne is once again following the lead of Dawkins, who in 'The God Delusion' denounces the NCSE as part of the 'Neville Chamberlain school of evolutionists,' those equivocators who defend the science but refuse to engage with what the New Atheists perceive as the real root of the problem -- namely, religious belief. It all might sound like a petty internecine squabble, but the stakes are high. The statistics on public scientific illiteracy in the United States are notorious -- and they're at their worst on contentious, politicized issues such as climate change and the teaching of evolution. About 46 percent of Americans in polls agree with this stunning statement: 'God created human beings pretty much in their present form at one time within the last 10,000 years or so.' In this context, the New Atheists have chosen their course: confrontation. And groups like the NCSE have chosen the opposite route: Work with all who support the teaching of evolution regardless of their beliefs and attempt to sway those who are uncertain but perhaps convincible. Despite the resultant bitterness, however, there is at least one figure both sides respect -- the man who started it all: Charles Darwin. What would he have done in this situation? It turns out that late in life, when an atheist author asked permission to dedicate a book to Darwin, the great scientist wrote back his apologies and declined. For as Darwin put it, 'Though I am a strong advocate for free thought on all subjects, yet it appears to me (whether rightly or wrongly) that direct arguments against Christianity & theism produce hardly any effect on the public; & freedom of thought is best promoted by the gradual illumination of men's minds, which follows from the advance of science.' Darwin and Dawkins differ by much more than a few letters, then -- something the New Atheists ought to deeply consider. Mooney and Kirshenbaum are co-authors of the new book, 'Unscientific America: How Scientific Illiteracy Threatens Our Future.'
