The Brain Chemistry of the Buddha

In 'The God Gene,' geneticist Dean Hamer says human spirituality may have an innate genetic component to it.

Dean Hamer is a molecular biologist at the National Institutes of Health, where he heads the Gene Structure and Regulation section at the National Cancer Institute. In his latest book, Hamer says certain brain chemicals affect higher consciousness and spirituality, and that the actions of these chemicals are linked to a gene his team has researched. He spoke to us recently about "The God Gene: How Faith Is Hardwired into Our Genes."

What is the God gene?

The God gene refers to the idea that human spirituality has an innate genetic component to it. It doesn't mean that there's one gene that makes people believe in God, but it refers to the fact that humans inherit a predisposition to be spiritual--to reach out and look for a higher being.

A big part of your research involved a "self-transcendence scale" to rate people's spirituality. What is this scale?

As you can imagine, it's not trivial to separate spirituality from more formal aspects of religion, but some psychologists like Robert Cloninger have tried to do that. They use a scale called "self-transcendence."

Overall, it tries to measure a sense of "at-oneness" with the universe independent of formal religious beliefs. More specifically, it actually looks at three different subscales. One of them is called self-forgetfulness: a measure of people's propensity to completely lose themselves in what they're doing, whether it's weeding the garden or meditating or whatever. People who are self-transcendent put less focus on themselves and more on everything outside of them. They see the connections to things.

A psychic component is called "transpersonal identification," a feeling of a sense of unity with everything else in the universe. Then there's a third scale called mysticism or spiritual acceptance which is more like, do you think mystical experiences have changed your life? Do you believe that science can't explain everything? Do you believe that there might be ESP, for example? Believing that there is more going on than meets the eye.

So you studied a certain gene to see how it related to this self-transcendence scale?
