When Explaining is Explaining Away

Critics accuse secular humanists of reductionism, of
assuming too hastily that mundane physical explanations explain away the need
for mystery. Yet a sufficiently powerful explanation will explain some mysteries
away. For example, once one truly understands the idea of living on a rotating
planet, ancient notions of the sun circling the Earth lose all force despite our
naïve experience of its east-to-west procession through the sky. A firm grasp
of evolutionary theory dispels the need to posit a cosmic designer. Today, brain
research is providing mundane explanations for phenomena that many relied on to
demonstrate the existence of the supernatural.
“Religious experience” or “mystical experience” is
an altered state of consciousness in which one’s perceived relationship to the
world shifts profoundly. One may feel oceanic oneness with the universe, or an
eerie sense of encountering some exalted Other. Like out-of-body experiences and
near-death experiences, mystical experience is valid in the very limited sense
that some people genuinely have the experience. But it’s subjective—a trick
the brain plays on us, not an experience of anything real in the world.
New technologies that image blood flow and electrical
activity in the conscious brain show how the trick is played. Recent studies
reveal the mechanics of religious experience so fully that little room for
mystery remains. University of Pennsylvania neurologist Andrew B. Newberg imaged
the brains of meditating Tibetan Buddhist adepts. He found more activity in the
frontal lobe, associated with concentration, and less in the parietal lobe that
is thought to generate our sense of the body’s orientation in space. Result:
an intensely “real” sensation of passing outside the physical world—and a
powerful, purely physical explanation for the sensation of oneness with the
cosmos. What about encounter experiences? Michael Persinger, a Laurentian
University neuroscientist, fits volunteers with a helmet that swirls weak
electromagnetic fields into their temporal lobes. About 80 percent clearly
experience a numinous Other; most interpret it in religious terms. Persinger
draws the conclusion any atheist would: “Religion is a property of the brain,
only the brain, and has little to do with what’s out there.”
Others disagree, Newberg for one. His book Why God Won’t
Go Away: Brain Science and the Biology of Belief triggered a spring flood of
media attention, including a Newsweek cover story.1
To Newberg, the fact that religious experience has specific brain mechanisms is
actually a sign that God exists: humans are hard-wired for religion because God
gave us this avenue by which to experience him. University of Kansas
psychologist Daniel Batson agrees. He scoffs at reductionism: “To say the
brain produces religion is like saying a piano produces music.”
Such arguments share an underlying desperation. The
faithful yearn to cling to God, or spirituality, or the oneness of being while
accommodating scientific findings that scour the foundations out from under
those beliefs. As Christian philosopher Nancey Murphy admitted to the Washington
Post, brain research into religious experience “reinforces atheistic
assumptions and makes religion appear useless. If you can explain religious
experience purely as a brain phenomenon, you don’t need the assumption of the
existence of God.”2 Hear, hear.
Religious experience hasn’t merely been explained. It’s
on the threshold of being explained away, if that hasn’t already occurred—a
development secular humanists should welcome. Believers will go on spinning
rationalizations, trying to reconcile ancient mystical ideas with research
findings that make them unnecessary. They’ll probably generate a few more
best-sellers along the way. But I can’t help thinking that on some level, the
Andrew Newbergs of the world already know they’ve lost.
