Although Daniel Everett was a missionary, far from converting the Pirahas, they converted him. He shows the slow, meticulous steps by which he gradually mastered their language and his gradual realisation that its unusual nature closely reflected its speakers' startlingly original perceptions of the world. Everett describes how he began to realise that his discoveries about the Piraha language opened up a new way of understanding how language works in our minds and in our lives, and that this way was utterly at odds with Noam Chomsky's universally accepted linguistic theories. The perils of passionate academic opposition were then swiftly conjoined to those of the Amazon in a debate whose outcome has yet to be won. Everett's views are most recently discussed in Tom Wolfe's bestselling The Kingdom of Speech. Adventure, personal enlightenment and the makings of a scientific revolution proceed together in this vivid, funny and moving book.

In his groundbreaking new book Daniel Everett seeks answers to questions that have perplexed thinkers from Plato to Chomsky: when and how did language begin? What is it? And what is it for?

Daniel Everett confounds the conventional wisdom that language originated with Homo sapiens 150,000 years ago and that we have a 'language instinct'. Drawing on evidence from a wide range of fields, including linguistics, archaeology, biology, anthropology and neuroscience, he shows that our ancient ancestors, Homo erectus, had the biological and mental equipment for speech one and half million years ago, and that their cultural and technological achievements (including building ocean-going boats) make it overwhelmingly likely they spoke some kind of language.

How Language Began sheds new light on language and culture and what it means to be human and, as always, Daniel Everett spices his account with incident and anecdote. His book is convincing, arresting and entertaining.

Like other tools, language was invented, can be reinvented or lost, and shows significant variation across cultures. It's as essential to survival as fire - and, like fire, is found in all human societies. Language presents the bold and controversial idea that language is not an innate component of the brain, as has been famously argued by Chomsky and Pinker. Rather, it's a cultural tool which varies much more across different societies than the innateness view suggests. Fusing adventure, anthropology, linguistics and psychology, and drawing on Everett's pioneering research with the Amazonian Pirahas, Language argues that language is embedded within - and is inseparable from - its specific culture. This book is like a fire that will generate much light. And much heat.
