Deus Ex Machina

"To seal the case for the temporal lobe’s involvement, Michael Persinger of Laurentian University in Ontario sought to artificially re-create religious feelings by electrically stimulating that large subdivision of the brain. So Persinger created the “God helmet,” which generates weak electromagnetic fields and focuses them on particular regions of the brain’s surface.

In a series of studies conducted over the past several decades, Persinger and his team have trained their device on the temporal lobes of hundreds of people. In doing so, the researchers induced in most of them the experience of a sensed presence—a feeling that someone (or a spirit) is in the room when no one, in fact, is—or of a profound state of cosmic bliss that reveals a universal truth. During the three-minute bursts of stimulation, the affected subjects translated this perception of the divine into their own cultural and religious language—terming it God, Buddha, a benevolent presence or the wonder of the universe.

Persinger thus argues that religious experience and belief in God are merely the results of electrical anomalies in the human brain. He opines that the religious bents of even the most exalted figures—for instance, Saint Paul, Moses, Muhammad and Buddha—stem from such neural quirks. The popular notion that such experiences are good, argues Persinger in his book Neuropsychological Bases of God Beliefs (Praeger Publishers, 1987), is an outgrowth of psychological conditioning in which religious rituals are paired with enjoyable experiences. Praying before a meal, for example, links prayer with the pleasures of eating. God, he claims, is nothing more mystical than that."
