Thoughts in a Haystack

"If you have negative sentiments toward religion," he tells them, "the box will destroy whatever you put inside it." Many of his students say they doubt the existence of God ... Put your pencil into the magic box, he tells them, and the nonbelievers do so blithely. Put in your driver’s license, he says, and most do, but only after significant hesitation. And when he tells them to put in their hands, few will.

If they don’t believe in God, what exactly are they afraid of?

When a trait is universal, evolutionary biologists look for a genetic explanation and wonder how that gene or genes might enhance survival or reproductive success. In many ways, it’s an exercise in post-hoc hypothesizing [sometimes called by detractors "just-so stories"] ...

So many aspects of religious belief involve misattribution and misunderstanding of the real world. Wouldn’t this be a liability in the survival-of-the-fittest competition? To Atran, religious belief requires taking "what is materially false to be true" and "what is materially true to be false." One example of this is the belief that even after someone dies and the body demonstrably disintegrates, that person will still exist, will still be able to laugh and cry, to feel pain and joy. This confusion "does not appear to be a reasonable evolutionary strategy," Atran wrote in "In Gods We Trust: The Evolutionary Landscape of Religion" in 2002. "Imagine another animal that took injury for health or big for small or fast for slow or dead for alive. It’s unlikely that such a species could survive."

Anthropologists psychologists since the turn of the 20th Century had been looking at the roots of religion, but the mutual hands-off policy began to shift in earnest in the 1990s.

Religion made incursions into the traditional domain of science with attempts to bring intelligent design into the biology classroom and to choke off human embryonic stem-cell research on religious grounds. Scientists responded with counterincursions. Experts from the hard sciences, like evolutionary biology and cognitive neuroscience, joined anthropologists and psychologists in the study of religion, making God an object of scientific inquiry.

[O]ne prominent member of the byproduct camp, Justin Barrett, is an observant Christian who believes in "an all-knowing, all-powerful, perfectly good God who brought the universe into being" ...

How does his view of God as a byproduct of our mental architecture coexist with his Christianity? Why doesn’t the byproduct theory turn him into a skeptic?

"Christian theology teaches that people were crafted by God to be in a loving relationship with him and other people," Barrett wrote in his e-mail message. "Why wouldn’t God, then, design us in such a way as to find belief in divinity quite natural?" Having a scientific explanation for mental phenomena does not mean we should stop believing in them, he wrote. "Suppose science produces a convincing account for why I think my wife loves me — should I then stop believing that she does?"
