  In the late nineteenth century, several European powers laid claim to African territories. Fearing that conflicting claims might lead to an all-out European war, the concerned parties got together in Berlin in 1884 and divided Africa as if it were a pie. Back then much of the African interior was terra incognita to Europeans. The British, French and Germans had accurate maps of Africa’s coastal regions, and knew precisely where the Niger, Congo and Zambezi empty into the ocean. However, they knew little about the course these rivers took inland, about the kingdoms and tribes that lived along their banks, and about local religion, history and geography. This hardly mattered to the European diplomats. They unrolled a half-empty map of Africa over a well-polished Berlin table, sketched a few lines here and there, and divided the continent among them.

  When in due course the Europeans penetrated the African interior, armed with their agreed-upon map, they discovered that many of the borders drawn in Berlin did little justice to the geographic, economic and ethnic reality of Africa. However, to avoid renewed clashes, the invaders stuck to their agreements, and these imaginary lines became the actual borders of European colonies. During the second half of the twentieth century, as the European empires disintegrated and their colonies gained independence, the new countries accepted the colonial borders, fearing that the alternative would be endless wars and conflicts. Many of the difficulties faced by present-day African countries stem from the fact that their borders make little sense. When the written fantasies of European bureaucracies encountered the African reality, reality was forced to surrender.5

  Our modern education systems provide numerous other examples of reality kowtowing to written records. When measuring the width of my desk, the yardstick I am using matters little. The width of my desk remains the same whether I say it is 200 centimetres or 78.74 inches. However, when bureaucracies measure people, the yardsticks they choose make all the difference. When schools began assessing people according to precise numerical marks, the lives of millions of students and teachers changed dramatically. Marks are a relatively new invention. Hunter-gatherers were never marked for their achievements, and even thousands of years after the Agricultural Revolution, few education establishments used precise marks. At the end of the year a medieval apprentice cobbler did not receive a piece of paper saying he has got an A in shoelaces but a C minus in buckles. An undergraduate in Shakespeare’s day left Oxford with one of only two possible results – with a degree, or without one. Nobody thought of giving one student a final mark of 74 and another student an 88.6

  It was the mass education systems of the industrial age that began using precise marks on a regular basis. After both factories and government ministries became accustomed to thinking in the language of numbers, schools followed suit. They started to gauge the worth of each student according to his or her average mark, whereas the worth of each teacher and principal was judged according to the school’s overall average. Once bureaucrats adopted this yardstick, reality was transformed.

  Originally, schools were supposed to focus on enlightening and educating students, and marks were merely a means of measuring success. But naturally enough schools soon began focusing on achieving high marks. As every child, teacher and inspector knows, the skills required to get high marks in an exam are not the same as a true understanding of literature, biology or mathematics. Every child, teacher and inspector also knows that when forced to choose between the two, most schools will go for the marks.

  The power of written records reached its apogee with the appearance of holy scriptures. Priests and scribes in ancient civilisations became accustomed to seeing documents as guidebooks for reality. At first, the texts told them about the reality of taxes, fields and granaries. But as the bureaucracy gained power, so the texts gained authority. Priests recorded not only lists of the god’s property, but also the god’s deeds, commandments and secrets. The resulting scriptures purported to describe reality in its entirety, and generations of scholars became accustomed to looking for all the answers in the pages of the Bible, the Qur’an or the Vedas.

  In theory, if some holy book misrepresented reality, its disciples would sooner or later discover this, and the text’s authority would be undermined. Abraham Lincoln said you cannot deceive everybody all the time. Well, that’s wishful thinking. In practice, the power of human cooperation networks depends on a delicate balance between truth and fiction. If you distort reality too much, it will weaken you, and you will not be able to compete against more clear-sighted rivals. On the other hand, you cannot organise masses of people effectively without relying on some fictional myths. So if you stick to unalloyed reality, without mixing any fiction with it, few people will follow you.

  If you used a time machine to send a modern scientist to ancient Egypt, she would not be able to seize power by exposing the fictions of the local priests and lecturing the peasants on evolution, relativity and quantum physics. Of course, if our scientist could use her knowledge in order to produce a few rifles and artillery pieces, she could gain a huge advantage over pharaoh and the crocodile god Sobek. Yet in order to mine iron ore, build blast furnaces and manufacture gunpowder the scientist would need a lot of hard-working peasants. Do you really think she could inspire them by explaining that energy divided by mass equals the speed of light squared? If you happen to think so, you are welcome to travel to present-day Afghanistan or Syria and try your luck.

  Really powerful human organisations – such as pharaonic Egypt, the European empires and the modern school system – are not necessarily clear-sighted. Much of their power rests on their ability to force their fictional beliefs on a submissive reality. That’s the whole idea of money, for example. The government makes worthless pieces of paper, declares them to be valuable and then uses them to compute the value of everything else. The government has the power to force citizens to pay taxes using these pieces of paper, so the citizens have no choice but to get their hands on at least some of them. Consequently, these bills really do become valuable, the government officials are vindicated in their beliefs, and since the government controls the issuing of paper money, its power grows. If somebody protests that ‘These are just worthless pieces of paper!’ and behaves as if they are only pieces of paper, he won’t get very far in life.

  The same thing happens when the education system declares that matriculation exams are the best method to evaluate students. The system has sufficient authority to influence admission standards to colleges and hiring standards in government offices and in the private sector. Students therefore invest all their efforts in getting good marks. Coveted positions are occupied by people with high marks, who naturally support the system that brought them there. The fact that the education system controls the critical exams gives it more power, and increases its influence over colleges, government offices and the job market. If somebody protests that ‘The degree certificate is just a piece of paper!’ and behaves accordingly, he is unlikely to get very far in life.

  Holy scriptures work the same way. The religious establishment proclaims that the holy book contains the answers to all our questions. It simultaneously presses courts, governments and businesses to behave according to what the holy book says. When a wise person reads scriptures and then looks at the world, he sees that there is indeed a good match. ‘Scriptures say that you must pay tithes to God – and look, everybody pays. Scriptures say that women are inferior to men, and cannot serve as judges or even give testimony in court – and look, there are indeed no women judges and the courts reject their testimony. Scriptures say that whoever studies the word of God will succeed in life – and look, all the good jobs are indeed held by people who know the holy book by heart.’

  Such a wise person will naturally begin to stu
dy the holy book, and because he is wise, he will become a scriptural pundit and be appointed a judge. When he becomes a judge, he will not allow women to bear witness in court, and when he chooses his successor, he will obviously pick somebody who knows the holy book well. If someone protests that ‘This book is just paper!’ and behaves accordingly, such a heretic will not get very far in life.

  Even when scriptures mislead people about the true nature of reality, they can nevertheless retain their authority for thousands of years. For instance, the biblical perception of history is fundamentally flawed, yet it managed to spread throughout the world, and many millions still believe in it. The Bible peddled a monotheistic theory of history, claiming that the world is governed by a single all-powerful deity, who cares above all else about me and my doings. If something good happens, it must be a reward for my good deeds. Any catastrophe must surely be punishment for my sins.

  Thus the ancient Jews believed that if they suffered from drought, or if King Nebuchadnezzar of Babylonia invaded Judaea and exiled its people, surely these were divine punishments for their own sins. And if King Cyrus of Persia defeated the Babylonians and allowed the Jewish exiles to return home and rebuild Jerusalem, God in his mercy must have heard their remorseful prayers. The Bible doesn’t recognise the possibility that perhaps the drought resulted from a volcanic eruption in the Philippines, that Nebuchadnezzar invaded in pursuit of Babylonian commercial interests and that King Cyrus had his own political reasons to favour the Jews. The Bible accordingly shows no interest whatsoever in understanding the global ecology, the Babylonian economy or the Persian political system.

  Such self-absorption characterises all humans in childhood. Children of all religions and cultures think they are the centre of the world, and therefore show little genuine interest in the conditions and feelings of other people. That’s why divorce is so traumatic for children. A five-year-old cannot understand that something important is happening for reasons unrelated to him. No matter how many times mommy and daddy tell him that they are independent people with their own problems and wishes, and that they didn’t divorce because of him – the child cannot absorb it. He is convinced that everything happens because of him. Most people grow out of this infantile delusion. Monotheists hold on to it till the day they die. Like a child thinking that his parents are fighting because of him, the monotheist is convinced that the Persians are fighting the Babylonians because of him.

  Already in biblical times some cultures had a far more accurate perception of history. Animist and polytheist religions depicted the world as the playground of numerous different powers rather than a single god. It was consequently easy for animists and polytheists to accept that many events are unrelated to me or to my favourite deity, and they are neither punishments for my sins nor rewards for my good deeds. Greek historians such as Herodotus and Thucydides, and Chinese historians such as Sima Qian, developed sophisticated theories of history that are very similar to our own modern views. They explained that wars and revolutions break out due to myriad political, social and economic factors. People may fall victim to war through no fault of their own. Accordingly, Herodotus developed a keen interest in understanding Persian politics, while Sima Qian was very concerned about the culture and religion of barbarous steppe people.7

  Present-day scholars agree with Herodotus and Sima Qian rather than with the Bible. That’s why all modern states invest so much effort in collecting information about other countries, and in analysing global ecological, political and economic trends. When the US economy falters, even evangelical Republicans sometimes point an accusing finger at China rather than at their own sins.

  Yet even though Herodotus and Thucydides understood reality much better than the authors of the Bible, when the two world views collided, the Bible won by a knockout. The Greeks adopted the Jewish view of history, rather than vice versa. A thousand years after Thucydides, the Greeks became convinced that if some barbarian horde invaded, surely it was divine punishment for their sins. No matter how mistaken the biblical world view was, it provided a better basis for large-scale human cooperation.

  Indeed, even today when US presidents take their oath of office, they put their hand on a Bible. Similarly in many countries around the world, including the USA and the UK, witnesses in courts put their hand on a Bible when swearing to tell the truth, the whole truth and nothing but the truth. It’s ironic that they swear to tell the truth on a book brimming with so many fictions, myths and errors.

  But it Works!

  Fictions enable us to cooperate better. The price we pay is that the same fictions also determine the goals of our cooperation. So we may have very elaborate systems of cooperation, which are harnessed to serve fictional aims and interests. Consequently the system may seem to be working well, but only if we adopt the system’s own criteria. For example, a Muslim mullah would say: ‘Our system works. There are now 1.5 billion Muslims worldwide, and more people study the Qur’an and submit themselves to Allah’s will than ever before.’ The key question, though, is whether this is the right yardstick for measuring success. A school principal would say: ‘Our system works. During the last five years, exam results have risen by 7.3 per cent.’ Yet is that the best way to judge a school? An official in ancient Egypt would say: ‘Our system works. We collect more taxes, dig more canals and build bigger pyramids than anyone else in the world.’ True enough, pharaonic Egypt led the world in taxation, irrigation and pyramid construction. But is that what really counts?

  People have many material, social and psychological needs. It is far from clear that peasants in ancient Egypt enjoyed more love or better social relations than their hunter-gatherer ancestors, and in terms of nutrition, health and child mortality it seems that life was actually worse. A document dated c.1850 BC from the reign of Amenemhat III – the pharaoh who created Lake Fayum – tells of a well-to-do man called Dua-Khety who took his son Pepy to school, so that he could learn to be a scribe. While on their way, Dua-Khety portrayed the miserable life of peasants, labourers, soldiers and artisans, so as to encourage Pepy to devote all his energy to studying and thereby escape the unhappy destiny of most humans.

  According to Dua-Khety, the life of a landless field labourer is full of hardship and misery. Dressed in mere tatters, he works all day till his fingers are covered in blisters. Then pharaoh’s officials come and take him away to do forced labour. In return for all his hard work he receives only sickness as payment. Even if he makes it home alive, he will be completely worn out and ruined. The fate of the landholding peasant is hardly better. He spends his days carrying water in buckets from the river to the field. The heavy load bends his shoulders and covers his neck with festering swellings. In the morning he has to water his plot of leeks, in the afternoon his date palms and in the evening his coriander field. Eventually he drops down and dies.8 The text might be exaggerating things on purpose, but not by much. Pharaonic Egypt was the most powerful kingdom of its day, but for the simple peasant all that power meant taxes and forced labour rather than clinics and social security services.

  This was not a uniquely Egyptian defect. Despite all the immense achievements of the Chinese dynasties, the Muslim empires and the European kingdoms, even in ad 1850 the life of the average person was not better – and might actually have been worse – than the lives of archaic hunter-gatherers. In 1850 a Chinese peasant or a Manchester factory hand worked longer hours than their hunter-gatherer ancestors; their jobs were physically harder and mentally less fulfilling; their diet was less balanced; hygiene conditions were incomparably worse; and infectious diseases were far more common.

  Suppose you were given a choice between the following two vacation packages:

  Stone Age package: On day one we will hike for ten hours in a pristine forest, setting camp for the night in a clearing by a river. On day two we will canoe down the river for ten hours, camping on the shores of a small lake. On day three we will learn from the native people how to fish in the lake and how to find
mushrooms in the nearby woods.

  Modern proletarian package: On day one we will work for ten hours in a polluted textile factory, passing the night in a cramped apartment block. On day two we will work for ten hours as cashiers in the local department store, going back to sleep in the same apartment block. On day three we will learn from the native people how to open a bank account and fill out mortgage forms.

  Which package would you choose?

  Hence when we come to evaluate human cooperation networks, it all depends on the yardsticks and viewpoint we adopt. Are we judging pharaonic Egypt in terms of production, nutrition or perhaps social harmony? Do we focus on the aristocracy, the simple peasants, or the pigs and crocodiles? History isn’t a single narrative, but thousands of alternative narratives. Whenever we choose to tell one, we are also choosing to silence others.

  Human cooperative networks usually judge themselves by yardsticks of their own invention and, not surprisingly, they often give themselves high marks. In particular, human networks built in the name of imaginary entities such as gods, nations and corporations normally judge their success from the viewpoint of the imaginary entity. A religion is successful if it follows divine commandments to the letter; a nation is glorious if it promotes the national interest; and a corporation thrives if it makes a lot of money.

  When examining the history of any human network, it is therefore advisable to stop from time to time and look at things from the perspective of some real entity. How do you know if an entity is real? Very simple – just ask yourself, ‘Can it suffer?’ When people burn down the temple of Zeus, Zeus doesn’t suffer. When the euro loses its value, the euro doesn’t suffer. When a bank goes bankrupt, the bank doesn’t suffer. When a country suffers a defeat in war, the country doesn’t really suffer. It’s just a metaphor. In contrast, when a soldier is wounded in battle, he really does suffer. When a famished peasant has nothing to eat, she suffers. When a cow is separated from her newborn calf, she suffers. This is reality.
