A journey to some of the Earth's most endangered people in the remote Upper Amazon. . . . a look at the rituals of the Bwiti cults of Gabon and Zaire. . . . . a field watch on the eating habits of 'stoned' apes and chimpanzees - these adventures are all a part of ethnobotanist Terence McKenna's extraordinary quest to discover the fruit of the Tree of Knowledge. He wonders why, as a species, we are so fascinated by altered states of consciousness. Can they reveal something about our origins as human beings and our place in nature? As an odyssey of mind, body and spirit, Food of the Gods is one of the most fascinating and surprising histories of consciousness ever written. And as a daring work of scholarship and exploration, it offers an inspiring vision for individual fulfilment and a humane basis for our interaction which each other and with the natural world. 'Brilliant, provocative, opinionated, poetic and inspiring. . . . . Essential reading for anyone who ever wondered why people take drugs.' Rupert Sheldrake
