Three important revolutions shaped the course of history: the Cognitive Revolution kick-started history about 70,000 years ago. The Agricultural Revolution sped it up about 12,000 years ago. The Scientific Revolution, which got under way only 500 years ago, may well end history and start something completely different. This book tells the story of how these three revolutions have affected humans and their fellow organisms.

most cherished desires of present-day Westerners are shaped by romantic, nationalist, capitalist and humanist myths that have been around for centuries. Friends giving advice often tell each other, ‘Follow your heart.’ But the heart is a double agent that usually takes its instructions from the dominant myths of the day, and the very recommendation to ‘follow your heart’ was implanted in our minds by a combination of nineteenth-century Romantic myths and twentieth-century consumerist myths. The Coca-Cola Company, for example, has marketed Diet Coke around the world under the slogan ‘Diet Coke. Do what feels good.’ Even what people take to be their most personal desires are usually programmed by the imagined order. Let’s consider, for example, the popular desire to take a holiday abroad. There is nothing natural or obvious about this. A chimpanzee alpha male would never think of using his power in order to go on holiday into the territory of a neighbouring chimpanzee band. The elite of ancient Egypt spent their fortunes building pyramids and having their corpses mummified, but none of them thought of going shopping in Babylon or taking a skiing holiday in Phoenicia. People today spend a great deal of money on holidays abroad because they are true believers in the myths of romantic consumerism. Romanticism tells us that in order to make the most of our human potential we must have as many different experiences as we can. We must open ourselves to a wide spectrum of emotions; we must sample various kinds of relationships; we must try different cuisines; we must learn to appreciate different styles of music. One of the best ways to do all that is to break free from our daily routine, leave behind our familiar setting, and go travelling in distant lands, where we can ‘experience’ the culture, the smells, the tastes and the norms of other people. We hear again and again the romantic myths about ‘how a new experience opened my eyes and changed my life’. Consumerism tells u

While a good story must give me a role, and must extend beyond my horizons, it need not be true. A story can be pure fiction, and yet provide me with an identity and make me feel that my life has meaning. Indeed, to the best of our scientific understanding, none of the thousands of stories that different cultures, religions and tribes have invented throughout history is true. They are all just human inventions. If you ask for the true meaning of life and get a story in reply, know that this is the wrong answer. The exact details don’t really matter. Any story is wrong, simply for being a story. The universe just does not work like a story.
So why do people believe in these fictions? One reason is that their personal identity is built on the story. People are taught to believe in the story from early childhood. They hear it from their parents, their teachers, their neighbours and the general culture long before they develop the intellectual and emotional independence necessary to question and verify such stories. By the time their intellect matures, they are so heavily invested in the story, that they are far more likely to use their intellect to rationalise the story than to doubt it. Most people who go on identity quests are like children going treasure hunting. They find only what their parents have hidden for them in advance.
Second, not only our personal identities but also our collective institutions are built on the story. Consequently, it is extremely frightening to doubt the story. In many societies, anyone who tries to do so is ostracised or persecuted. Even if not, it takes strong nerves to question the very fabric of society. For if indeed the story is false, then the entire world as we know it makes no sense. State laws, social norms, economic institutions – they might all collapse.
