Peter Watson's hugely ambitious and stimulating history of ideas from deep antiquity to the present day—from the invention of writing, mathematics, science, and philosophy to the rise of such concepts as the law, sacrifice, democracy, and the soul—offers an illuminated path to a greater understanding of our world and ourselves. “This is a grand book...The history of ideas deserves treatment on this scale.” - Felipe Fernandez-Armesto, Evening Standard (London) “[An] extraordinary new book....This is the history of ‘ideas’ as it has never been presented before.” - Noel Malcolm, Sunday Telegraph (London) “A masterpiece of historical writing.” - John Gray, Professor of European Thought, London School of Economics, New Statesman “A superior specimen, with numerous interesting factoids...thought-provoking short essays.” - John Derbyshire, New York Sun Peter Watson's hugely ambitious and stimulating history of ideas from deep antiquity to the present day—from the invention of writing, mathematics, science, and philosophy to the rise of such concepts as the law, sacrifice, democracy, and the soul—offers an illuminated path to a greater understanding of our world and ourselves.

Ideas A History of Thought and Invention, from Fire to Freud By Peter Watson HarperCollins Publishers, Inc. Copyright © 2006 Peter Watson All right reserved. ISBN: 0060935642 Chapter One Ideas Before Language George Schaller, director of the Wildlife Conservation Division of the New York Zoological Society, is known to his fellow biologists as a meticulous observer of wild animals. In a long and distinguished career he has made many systematic studies of lions, tigers, cheetahs, leopards, wild dogs, mountain gorillas and hyenas. His book, The Last Panda , published in 1993, recorded many new and striking facts about the animal the Chinese call the 'bearcat'. He found that on one occasion a sick panda had gone freely to a human family in the Wolong area, where it was fed sugar and rice porridge for three days, until it recovered and returned to the forest. 1 In the late 1960s Schaller and a colleague spent a few days on the Serengeti plain in Tanzania, East Africa, where they made a simple observation which had escaped everyone else. In the course of those few days, they stumbled across quite a lot of dead meat 'just lying around'. They found dead buffalo, the butchered remains of lion kills, and they also came across a few incapacitated animals that would have been easy prey for carnivores. Smaller deer (like Thompson's gazelles) remained uneaten for barely a day but larger animals, such as adult buffalo, 'persisted as significant food resources' for about four days. 2 Schaller concluded from this that early humans could have survived quite easily on the Serengeti simply by scavenging, that there was enough 'ruin' in the bush for them to live on without going hunting. Other colleagues subsequently pointed out that even today the Hadza, a hunter-gathering tribe who live in northern Tanzania, sometimes scavenge by creeping up on lions who have made a kill and then creating a loud din. The lions are frightened away. This outline of man's earliest lifestyle is conjectural. 3 And to dignify the practice as an 'idea' is surely an exaggeration: this was instinct at work. But scavenging, unromantic as it sounds, may not be such a bad starting-point. It may even be that the open African savannah was the type of environment which favoured animals who were generalists, as much as specialists, like a hippopotamus, for example, or a giraffe, and it is this which stimulated mankind's intelligence in the first place. The scavenging hypothesis has, however, found recent support from a study of the marks made on bones excavated at palaeontological sites: animals killed by carnivores do show tool marks but fewer than those butchered by humans. It is important to stress that meat-eating in early humans does not, in and of itself, imply hunting. 4 There are two candidates for humankind's first idea, one rather more hypothetical than the other. The more hypothetical relates to bipedalism. For a long time, ever since the publication of The Descent of Man by Charles Darwin in 1871, the matter of bipedalism was felt to be a non-issue. Following Darwin, everyone assumed that man's early ancestors descended from the trees and began to walk upright because of changes in the climate, which made rainforest scarcer and open savannah more common.
