For a 2,500-year-old religion, Buddhism seems remarkably compatible with our scientifically oriented culture, which may explain its surging popularity here in America. Over the last 15 years, the number of Buddhist centers in the United States has more than doubled, to well over 1,000. As many as 4 million Americans now practice Buddhism, surpassing the total of Episcopalians. Of these Buddhists, half have post-graduate degrees, according to one survey. Recently, convergences between science and Buddhism have been explored in a slew of books—including Zen and the Brain and The Psychology of Awakening—and scholarly meetings. Next fall Harvard will host a colloquium titled “Investigating the Mind,” where leading cognitive scientists will swap theories with the Dalai Lama. Just the other week the New York Times hailed the “rapprochement between modern science and ancient [Buddhist] wisdom.”
