Enlarge By Elise Amendola, AP Humanist chaplain Greg Epstein, left, talks with Harvard University students after a group meeting in Cambridge, Mass. Epstein envisions local humanist centers nationwide that perform many of the community-building functions of a church, only in service of the humanist creed, which he sums up as a commitment to living ethical, personally fulfilling lives while serving the greater good.

Setting aside the question of whether God exists, it's clear that the benefits of faith far outweigh its costs, he argues in his new book, An Atheist Defends Religion: Why Humanity is Better Off With Religion than Without It. FAITH & REASON: Atheist reader-reviewer takes on 'Jesus, Interrupted' 'NONES': People with 'no religion' gain on major denominations "I don't know if anybody is going to be able to convince me that God exists," Sheiman said in an interview, "but they can convince me that religion has intrinsic value." The old atheists said there was no God. The so-called "New Atheists" said there was no God, and they were vocally vicious about it. Now, the new "New Atheists" — call it Atheism 3.0 — say there's still no God, but maybe religion isn't all that bad. Faith provides meaning and purpose for millions of believers, inspires people to tend to each other and build communities, gives them a sense of union with a transcendent force, and provides numerous health benefits, Sheiman says. Moreover, the galvanizing force behind many achievements in Western civilization has been faith, Sheiman argues, while conceding that he limits his analysis, for the most part, to modern Western religion. "More than any other institution, religion deserves our appreciation and respect because it has persistently encouraged people to care deeply — for the self, for neighbors, for humanity, and for the natural world — and to strive for the highest ideals humans are able to envision," Sheiman writes. Religion has always had its cultured defenders, atheists who speak up for the social benefits of faith. The philosopher Plato, for instance, did not believe in the Greek pantheon, but argued that other people should, for the good of society. He even proposed criminalizing disbelief in the existence of deities and immortality of the soul. In recent years, the skeptical scene has been dominated by the New Atheists —Christopher Hitchens, Richard Dawkins, Sam Harris and others — who argue in best-selling books that religious faith is a mental illness, or worse. But now, a new crew of nonbelievers is taking on the New Atheists, arguing that while they may not have faith themselves, there's little reason to belittle believers or push religion out of the public square. The back-and-forth debates over God's existence have shed a little light, but far more heat, they argue, while the world's problems loom ever larger. "The work that we need to do, we atheists, humanists and non-believers, is to build a better world and not try to tear down those with whom we disagree," said Greg M. Epstein, the Humanist chaplain at Harvard University. "When our goal is erasing religion, rather than embracing human beings, we all lose." Epstein argues in his forthcoming book, Good without God: What a Billion Nonreligious People Do Believe, that morality does not depend on a judgmental deity and that nonbelievers can lead meaningful, even purpose-driven, lives. But they can also learn from people of faith, such as California megachurch pastor and Purpose Driven Life author Rick Warren, Epstein says. Warren's best-selling book basically says that "you have to have a purpose in life bigger than yourself, and that not everything is all about you," said Epstein. "And he's absolutely right about that. But he's wrong in saying that you have to believe in Jesus Christ and if you don't you're going to hell for eternity." Atheists who insist that religion be removed from the public square are doing themselves a disservice, argues Austin Dacey, a former United Nations representative for the staunchly secularist Center for Inquiry and author of The Secular Conscience: Why Belief Belongs in Public Life. A godless public square not only shields religion from public criticism, it also circumvents a broader debate on morality, he argues. "If they privatize faith, they also won't be able to criticize it," Dacey said of the New Atheists an interview. On the flip side, atheists too, can be a "blessing" for believers, said Samir Selmanovic, co-founder and co-leader of New York's interreligious Faith House Manhattan and author of It's Really All About God: Reflections of a Muslim Atheist Jewish Christian. Atheists are "God's whistle-blowers," who keep believers honest and focused on the here-and-now, Selmanovic said. "Atheism at its best grabs us by the collar and throws us to the ground, demanding to see lives well lived, forcing us to dig deeper and live up to the best of our own religions," he writes. While no one expects the God debate to end any time soon, in the meantime, perhaps people can agree to disagree a little more agreeably, the new New Atheists argue. "There was a moment when atheist books were selling," Dacey said. "But people like objectivity, they like the feeling of balance. So after this wave of atheist books and the criticism that they are extremist, people are trying to find a happy medium."
