Not only is religion thriving, but it is thriving because it helps people to adapt and survive in the world. In his book Darwin's Cathedral, evolutionary biologist David Sloan Wilson argues that religion provides something that secular society doesn't: a vision of transcendent purpose. Consequently, religious people have a zest for life that is, in a sense, unnatural. They exhibit a hopefulness about the future that may exceed what is warranted by how the world is going. And they forge principles of morality and charity that simply make them more cohesive, adaptive, and successful than groups whose members lack this binding and elevating force.
