The power of speech

Everett's discovery of the elegant linguistic theories of Chomsky was his second conversion experience. At the time, Chomsky was not merely known for his trenchant, left-leaning political activism but was revered as the father of modern linguistics for his theory of "universal grammar". Following Chomsky's idea that humans are innately programmed to produce language according to a fixed and finite set of rules, Everett studied for a doctorate in the 80s and took advice from Chomsky. Gradually, however, as he spent more time with the Pirahã, he came to doubt Chomsky's claims of universality.

These doubts exploded three years ago, like "a bomb thrown into the party" in the words of psychologist and linguist Steven Pinker, who initially welcomed Everett's findings against Chomsky before becoming more critical. In 2005, Everett published a paper about the Pirahã that rocked the foundations of universal grammar. Chomsky had recently refined his theory to argue that recursion - the linguistic practice of inserting phrases inside others - was the cornerstone of all languages. (An example of recursion is extending the sentence "Daniel Everett talked about the story of his life" to read, "Daniel Everett flew to London and talked about the story of his life".) Everett argued that he could find no evidence of recursion in Pirahã. This was deeply troubling for Chomsky's theory. If the Pirahã didn't use recursion, then how could it be a fundamental part of a universal grammar embedded in our genes? And if the Pirahã didn't use recursion, then is their language - and, by implication, other languages - determined not by biology but by culture?

Thirty years of living with the Pirahã has taught Everett that they exist almost completely in the present. Absorbed by the daily struggle to survive, they do not plan ahead, store food, build houses or canoes to last, maintain tools or talk of things beyond those that they, or people they know, have experienced. They are the "ultimate empiricists", he argues, and this culture of living in the present has shaped their language.

Everett's claims created a furore. Chomskyites rushed to defend universal grammar and academics cast doubt on Everett's view of the Pirahã. Nineteenth-century anthropologists had judged exotic peoples similarly, saying they had no creation myths and apparently crude languages that could not count or convey abstract thought, before it was proved it was our erroneous understanding of these "primitive" societies that was primitive. "By framing his observations as an anti-Chomsky discovery rather than as un-PC Eurocentric condescension, Everett was able to get away with claims that would have aroused the fury of anthropologists in any other context," wrote the increasingly sceptical Pinker, who argued that even if there was "a grain of truth" in the Pirahã's preoccupation with the here-and-now, it was by no means unique to their society. In other words, Everett was an almost racist throwback to the days of, well, missionaries.

Yet Everett's life with the Pirahã didn't just cause a gradual disenchantment with the Chomskyan intellectual framework he had once cherished: it also triggered another, even more dramatic, de-conversion.

Soon after he first arrived in the Amazon, Everett was nearly killed when the Pirahã discovered he was ordering passing river traders not to give them whisky. The Pirahã were rarely violent, but intensely rejected any kind of coercion. Crucially, Everett came to see his religion as fundamentally coercive. His academic studies were ultimately designed to help him translate the Bible into Pirahã. When they heard the word of God, his evangelic mission believed, they would be converted. Everett translated the Book of Luke, read it to the Pirahã and they were utterly unmoved. By 1985, he had privately lost his faith.

"It's wrong to try and convert tribal societies," he says. "What should the empirical evidence for religion be? It should produce peaceful, strong, secure people who are right with God and right with the world. I don't see that evidence very often. So then I find myself with the Pirahã. They have all these qualities that I am trying to tell them they could have. They are the ones who are living life the way I'm saying it ought to be lived, they just don't fear heaven and hell."
