— A Brief History of Humankind
Select Quotes
Part One: The Cognitive Revolution
1. An Animal Of No Significance
Homo sapiens, too, belongs to a family. This banal fact used to be one of history’s most closely guarded secrets. Homo sapiens long preferred to view itself as set apart from animals, an orphan who has no family, no cousins and–most importantly–no parents. But that’s just not the case. Like it or not, we are members of a large and particularly noisy family called the great apes. – Page 5
Humans emerge from the womb like molten glass from a furnace. They can be spun, stretched and shaped with a surprising degree of freedom. This is why today we can educate our children to become Christian or Buddhist, capitalist or socialist, warlike or peace-loving. – Page 10
Tolerance is not a Sapiens trademark. In modern times, a small difference in skin colour, dialect or religion has been enough to prompt one group of Sapiens to set about exterminating another group. – Page 18
When Charles Darwin indicated that Homo sapiens was just another kind of animal, people were outraged. Even today many refuse to believe it. Had the Neanderthals survived, would we still imagine ourselves to be a creature apart? Perhaps this is exactly why our ancestors wiped out the Neanderthals. They were too familiar to ignore, but too different to tolerate. – Page 18
2. The Tree Of Knowledge
The gossip theory might sound like a joke, but numerous studies support it. Even today the vast majority of human communication–whether in the form of emails, phone calls or newspaper columns–is gossip. It comes so naturally to us that it seems as if our language evolved for this very purpose. – Page 24
You could never convince a monkey to give you a banana by promising him limitless bananas after death in monkey heaven. – Page 24
People easily acknowledge that ‘primitive tribes’ cement their social order by believing in ghosts and spirits, and gathering each full moon to dance together around the campfire. What we fail to appreciate is that our modern institutions function on exactly the same basis. – Page 28
Peugeot is a figment of our collective imagination. – Page 29
Telling effective stories is not easy. The difficulty lies not in telling the story, but in convincing everyone else to believe it. Much of history revolves around this question: how does one convince millions of people to believe particular stories about gods, or nations, or limited liability companies? Yet when it succeeds, it gives Sapiens immense power, because it enables millions of strangers to cooperate and work towards common goals. – Page 31
Unlike lying, an imagined reality is something that everyone believes in, and as long as this communal belief persists, the imagined reality exerts force in the world. – Page 32
The Cognitive Revolution is accordingly the point when history declared its independence from biology. – Page 37
3. A Day In The Life Of Adam And Eve
Thanks to the appearance of fiction, even people with the same genetic make-up who lived under similar ecological conditions were able to create very different imagined realities, which manifested themselves in different norms and values. – Page 44
The heated debates about Homo sapiens’ ‘natural way of life’ miss the main point. Ever since the Cognitive Revolution, there hasn’t been a single natural way of life for Sapiens. There are only cultural choices, from among a bewildering palette of possibilities. – Page 45
Most members of agricultural and industrial societies are domesticated animals. They are not equal to their masters, of course, but they are members all the same. Today, the society called New Zealand is composed of 4.5 million Sapiens and 50 million sheep. – Page 45
What do you really need to know in order to get by as a computer engineer, an insurance agent, a history teacher or a factory worker? You need to know a lot about your own tiny field of expertise, but for the vast majority of life’s necessities you rely blindly on the help of other experts, whose own knowledge is also limited to a tiny field of expertise. – Page 49
The theories of scholars who claim to know what the foragers felt shed much more light on the prejudices of their authors than on Stone Age religions. – Page 55
Part Two: The Agricultural Revolution
5. History’S Biggest Fraud
How many young college graduates have taken demanding jobs in high-powered firms, vowing that they will work hard to earn money that will enable them to retire and pursue their real interests when they are thirty-five? But by the time they reach that age, they have large mortgages, children to school, houses in the suburbs that necessitate at least two cars per family, and a sense that life is not worth living without really good wine and expensive holidays abroad. – Page 87
One of history’s few iron laws is that luxuries tend to become necessities and to spawn new obligations. – Page 87
This discrepancy between evolutionary success and individual suffering is perhaps the most important lesson we can draw from the Agricultural Revolution. – Page 97
6. Building Pyramids
History is something that very few people have been doing while everyone else was ploughing fields and carrying water buckets. – Page 101
In fact, they are both wrong. Hammurabi and the American Founding Fathers alike imagined a reality governed by universal and immutable principles of justice, such as equality or hierarchy. Yet the only place where such universal principles exist is in the fertile imagination of Sapiens, and in the myths they invent and tell one another. These principles have no objective validity. – Page 108
We hold these truths to be self-evident, that all men evolved differently, that they are born with certain mutable characteristics, and that among these are life and the pursuit of pleasure. – Page 110
We believe in a particular order not because it is objectively true, but because believing in it enables us to cooperate effectively and forge a better society. Imagined orders are not evil conspiracies or useless mirages. Rather, they are the only way large numbers of humans can cooperate effectively. – Page 110
However, an imagined order cannot be sustained by violence alone. It requires some true believers as well. – Page 111
A single priest often does the work of a hundred soldiers–far more cheaply and effectively. – Page 111
Romanticism tells us that in order to make the most of our human potential we must have as many different experiences as we can. – Page 115
Peugeot, for example, is not the imaginary friend of Peugeot’s CEO. – Page 117
There is no way out of the imagined order. When we break down our prison walls and run towards freedom, we are in fact running into the more spacious exercise yard of a bigger prison. – Page 118
7. Memory Overload
The most important impact of script on human history is precisely this: it has gradually changed the way humans think and view the world. Free association and holistic thought have given way to compartmentalisation and bureaucracy. – Page 130
Writing was born as the maidservant of human consciousness, but is increasingly becoming its master. Our computers have trouble understanding how Homo sapiens talks, feels and dreams. So we are teaching Homo sapiens to talk, feel and dream in the language of numbers, which can be understood by computers. – Page 132
8. There Is No Justice In History
Many of those who signed the Declaration of Independence were slaveholders. They did not release their slaves upon signing the Declaration, nor did they consider themselves hypocrites. In their view, the rights of men had little to do with Negroes. – Page 133
Yet it is an iron rule of history that every imagined hierarchy disavows its fictional origins and claims to be natural and inevitable. – Page 134
The Bible decrees that ‘If a man meets a virgin who is not betrothed, and seizes her and lies with her, and they are found, then the man who lay with her shall give to the father of the young woman fifty shekels of silver, and she shall be his wife’ (Deuteronomy 22: 28–9). The ancient Hebrews considered this a reasonable arrangement. – Page 145
In fact, though, Mother Nature does not mind if men are sexually attracted to one another. It’s only human mothers and fathers steeped in particular cultures who make a scene if their son has a fling with the boy next door. – Page 146
Culture tends to argue that it forbids only that which is unnatural. But from a biological perspective, nothing is unnatural. Whatever is possible is by definition also natural. A truly unnatural behaviour, one that goes against the laws of nature, simply cannot exist, so it would need no prohibition. No culture has ever bothered to forbid men to photosynthesise, women to run faster than the speed of light, or negatively charged electrons to be attracted to each other. – Page 147
In truth, our concepts ‘natural’ and ‘unnatural’ are taken not from biology, but from Christian theology. The theological meaning of ‘natural’ is ‘in accordance with the intentions of the God who created nature’. – Page 147
Gender is a race in which some of the runners compete only for the bronze medal. – Page 153
Throughout Elizabeth’s forty-five-year reign, all Members of Parliament were men, all officers in the Royal Navy and army were men, all judges and lawyers were men, all bishops and archbishops were men, all theologians and priests were men, all doctors and surgeons were men, all students and professors in all universities and colleges were men, all mayors and sheriffs were men, and almost all the writers, architects, poets, philosophers, painters, musicians and scientists were men. – Page 153
Part Three: The Unification Of Humankind
9. The Arrow Of History
This network of artificial instincts is called ‘culture’. – Page 163
If tensions, conflicts and irresolvable dilemmas are the spice of every culture, a human being who belongs to any particular culture must hold contradictory beliefs and be riven by incompatible values. It’s such an essential feature of any culture that it even has a name: cognitive dissonance. – Page 165
If, say, a Christian really wants to understand the Muslims who attend that mosque down the street, he shouldn’t look for a pristine set of values that every Muslim holds dear. Rather, he should enquire into the catch-22s of Muslim culture, those places where rules are at war and standards scuffle. It’s at the very spot where the Muslims teeter between two imperatives that you’ll understand them best. – Page 165
Over the millennia, small, simple cultures gradually coalesce into bigger and more complex civilisations, so that the world contains fewer and fewer mega-cultures, each of which is bigger and more complex. – Page 166
At the micro level, it seems that for every group of cultures that coalesces into a mega-culture, there’s a mega-culture that breaks up into pieces. – Page 166
Yet as far as the emperors of China or the rulers of Mesopotamia were concerned, Tasmania could just as well have been located on one of Jupiter’s moons. – Page 167
native of Tangier, in Morocco, Ibn Battuta visited Timbuktu, Zanzibar, southern Russia, Central Asia, India, China and Indonesia. – Page 169
We begin with the story of the greatest conqueror in history, a conqueror possessed of extreme tolerance and adaptability, which consequently managed to gain the allegiance of all people. This conqueror is money. – Page 172
Osama Bin Laden, for all his hatred of American culture, American religion and American politics, was very fond of American dollars. – Page 172
10. The Scent Of Money
‘Everyone would work according to their abilities, and receive according to their needs’ turned out in practice into ‘everyone would work as little as they can get away with, and receive as much as they could grab’. – Page 176
This is perhaps its most basic quality. Everyone always wants money because everyone else also always wants money, which means you can exchange money for whatever you want or need. – Page 178
For thousands of years, philosophers, thinkers and prophets have besmirched money and called it the root of all evil. Be that as it may, money is also the apogee of human tolerance. Money is more open-minded than language, state laws, cultural codes, religious beliefs and social habits. Money is the only trust system created by humans that can bridge almost any cultural gap, and that does not discriminate on the basis of religion, gender, race, age or sexual orientation. Thanks to money, even people who don’t know each other and don’t trust each other can nevertheless cooperate effectively. – Page 186
Devout Christians have murdered, stolen and cheated–and later used their spoils to buy forgiveness from the church. – Page 186
11. Imperial Visions
It’s not our kind of story. We like to see underdogs win. But there is no justice in history. – Page 189
Second, empires are characterised by flexible borders and a potentially unlimited appetite. They can swallow and digest more and more nations and territories without altering their basic structure or identity. The British state of today has fairly clear borders that cannot be exceeded without altering the fundamental structure and identity of the state. A century ago almost any place on earth could have become part of the British Empire. – Page 190
The standard imperial toolkit included wars, enslavement, deportation and genocide. – Page 193
Evolution has made Homo sapiens, like other social mammals, a xenophobic creature. – Page 195
contradiction to the modern Western view that a just world is composed of separate nation states, in China periods of political fragmentation were seen as dark ages of chaos and injustice. – Page 197
India’s Muslim conquerors, such as the Taj Mahal? – Page 208
12. The Law Of Religion
Religion can thus be defined as a system of human norms and values that is founded on a belief in a superhuman order. – Page 210
Still, if we combine all the victims of all these persecutions, it turns out that in these three centuries, the polytheistic Romans killed no more than a few thousand Christians. 1 In contrast, over the course of the next 1,500 years, Christians slaughtered Christians by the millions to defend slightly different interpretations of the religion of love and compassion. – Page 215
So, monotheism explains order, but is mystified by evil. Dualism explains evil, but is puzzled by order. There is one logical way of solving the riddle: to argue that there is a single omnipotent God who created the entire universe–and He’s evil. But nobody in history has had the stomach for such a belief. – Page 221
How can a monotheist adhere to such a dualistic belief (which, by the way, is nowhere to be found in the Old Testament)? Logically, it is impossible. Either you believe in a single omnipotent God or you believe in two opposing powers, neither of which is omnipotent. Still, humans have a wonderful capacity to believe in contradictions. – Page 222
In fact, monotheism, as it has played out in history, is a kaleidoscope of monotheist, dualist, polytheist and animist legacies, jumbling together under a single divine umbrella. – Page 223
The theory of relativity is not a religion, because (at least so far) there are no human norms and values that are founded on it. – Page 229
Just as a Buddhist could worship Hindu deities, and just as a monotheist could believe in the existence of Satan, so the typical American nowadays is simultaneously a nationalist (she believes in the existence of an American nation with a special role to play in history), a free-market capitalist (she believes that open competition and the pursuit of self-interest are the best ways to create a prosperous society), and a liberal humanist (she believes that humans have been endowed by their creator with certain inalienable rights). – Page 230
Theist religions sanctify the gods. Humanist religions sanctify humanity, or more correctly, Homo sapiens. – Page 230
At the dawn of the third millennium, the future of evolutionary humanism is unclear. – Page 236
Yet over the last 200 years, the life sciences have thoroughly undermined this belief. Scientists studying the inner workings of the human organism have found no soul there. They increasingly argue that human behaviour is determined by hormones, genes and synapses, rather than by free will–the same forces that determine the behaviour of chimpanzees, wolves, and ants. – Page 236
Our judicial and political systems largely try to sweep such inconvenient discoveries under the carpet. But in all frankness, how long can we maintain the wall separating the department of biology from the departments of law and political science? – Page 236
13. The Secret Of Success
They can describe how Christianity took over the Roman Empire, but they cannot explain why this particular possibility was realised. What is the difference between describing ‘how’ and explaining ‘why’? To describe ‘how’ means to reconstruct the series of specific events that led from one point to another. To explain ‘why’ means to find causal connections that account for the occurrence of this particular series of events to the exclusion of all others. – Page 238
Not that everything is possible. Geographical, biological and economic forces create constraints. Yet these constraints leave ample room for surprising developments, which do not seem bound by any deterministic laws. – Page 239
‘Prophets who predict things that don’t happen?’ – Page 241
So why study history? Unlike physics or economics, history is not a means for making accurate predictions. We study history not to know the future but to widen our horizons, to understand that our present situation is neither natural nor inevitable, and that we consequently have many more possibilities before us than we imagine. – Page 241
Ever more scholars see cultures as a kind of mental infection or parasite, with humans as its unwitting host. – Page 242
This approach is sometimes called memetics. It assumes that, just as organic evolution is based on the replication of organic information units called ‘genes’, so cultural evolution is based on the replication of cultural information units called ‘memes’. 1 Successful cultures are those that excel in reproducing their memes, irrespective of the costs and benefits to their human hosts. – Page 242
Part Four: The Scientific Revolution
14. The Discovery Of Ignorance
Modern science is based on the Latin injunction ignoramus–‘we do not know’. It assumes that we don’t know everything. – Page 250
The Scientific Revolution has not been a revolution of knowledge. It has been above all a revolution of ignorance. The great discovery that launched the Scientific Revolution was the discovery that humans do not know the answers to their most important questions. – Page 251
In fact, the relationship between science and technology is a very recent phenomenon. Prior to 1500, science and technology were totally separate fields. – Page 259
A good historian can find precedent for everything. But an even better historian knows when these precedents are but curiosities that cloud the big picture. – Page 260
Until the Scientific Revolution most human cultures did not believe in progress. They thought the golden age was in the past, and that the world was stagnant, if not deteriorating. – Page 264
Throughout history, societies have suffered from two kinds of poverty: social poverty, which withholds from some people the opportunities available to others; and biological poverty, which puts the very lives of individuals at risk due to lack of food and shelter. – Page 266
In fact, in many societies more people are in danger of dying from obesity than from starvation. – Page 266
A few serious scholars suggest that by 2050, some humans will become a-mortal (not immortal, because they could still die of some accident, but a-mortal, meaning that in the absence of fatal trauma their lives could be extended indefinitely). – Page 271
Like all other parts of our culture, it is shaped by economic, political and religious interests. – Page 271
Assuming that the amount of money is limited, and that it is impossible to finance both research projects, which one should be funded? There is no scientific answer to this question. There are only political, economic and religious answers. – Page 273
Science is unable to set its own priorities. It is also incapable of determining what to do with its discoveries. – Page 274
In short, scientific research can flourish only in alliance with some religion or ideology. – Page 274
15. The Marriage Of Science And Empire
The Chinese and Persians did not lack technological inventions such as steam engines (which could be freely copied or bought). They lacked the values, myths, judicial apparatus and sociopolitical structures that took centuries to form and mature in the West and which could not be copied and internalised rapidly. – Page 282
What potential did Europe develop in the early modern period that enabled it to dominate the late modern world? There are two complementary answers to this question: modern science and capitalism. – Page 282
Due to their close cooperation with science, these empires wielded so much power and changed the world to such an extent that perhaps they cannot be simply labelled as good or evil. They created the world as we know it, including the ideologies we use in order to judge them. – Page 302
alike. – Page 303
in terms of historical differences between cultures rather than biological differences between races. We no longer say, ‘It’s in their blood.’ We say, ‘It’s in their culture.’ – Page 303
16. The Capitalist Creed
For better or worse, in sickness and in health, the modern economy has been growing like a hormone-soused teenager. – Page 305
Yet Smith’s claim that the selfish human urge to increase private profits is the basis for collective wealth is one of the most revolutionary ideas in human history–revolutionary not just from an economic perspective, but even more so from a moral and political perspective. What Smith says is, in fact, that greed is good, and that by becoming richer I benefit everybody, not just myself. Egoism is altruism. – Page 311
In the new capitalist creed, the first and most sacred commandment is: ‘The profits of production must be reinvested in increasing production.’ – Page 312
The British changed its name to New York. The remains of the wall built by WIC to defend its colony against Native Americans and British are today paved over by the world’s most famous street–Wall Street. – Page 322
At the end of the Middle Ages, slavery was almost unknown in Christian Europe. During the early modern period, the rise of European capitalism went hand in hand with the rise of the Atlantic slave trade. Unrestrained market forces, rather than tyrannical kings or racist ideologues, were responsible for this calamity. – Page 330
Much like the Agricultural Revolution, so too the growth of the modern economy might turn out to be a colossal fraud. The human species and the global economy may well keep growing, but many more individuals may live in hunger and want. – Page 333
17. The Wheels Of Industry
Just as the Atlantic slave trade did not stem from hatred towards Africans, so the modern animal industry is not motivated by animosity. – Page 343
The history of ethics is a sad tale of wonderful ideals that nobody can live up to. Most Christians did not imitate Christ, most Buddhists failed to follow Buddha, and most Confucians would have caused Confucius a temper tantrum. – Page 349
18. A Permanent Revolution
Perhaps 65 million years from now, intelligent rats will look back gratefully on the decimation wrought by humankind, just as we today can thank that dinosaur-busting asteroid. – Page 351
In the battle for human loyalty, national communities have to compete with tribes of customers. People who do not know one another intimately but share the same consumption habits and interests often feel – Page 364
At least some of the praise usually heaped on Mahatma Gandhi for his non-violent creed is actually owed to the British Empire. – Page 369
The independent states that came after these empires were remarkably uninterested in war. – Page 370
The Nobel Peace Prize to end all peace prizes should have been given to Robert Oppenheimer and his fellow architects of the atomic bomb. Nuclear weapons have turned war between superpowers into collective suicide, and made it impossible to seek world domination by force of arms. – Page 372
The answer is a matter of timing. It is sobering to realise how often our view of the past is distorted by events of the last few years. – Page 375
19. And They Lived Happily Ever After
Unfortunately for all hopes of creating heaven on earth, our internal biochemical system seems to be programmed to keep happiness levels relatively constant. – Page 386
The scientist who says her life is meaningful because she increases the store of human knowledge, the soldier who declares that his life is meaningful because he fights to defend his homeland, and the entrepreneur who finds meaning in building a new company are no less delusional than their medieval counterparts who found meaning in reading scriptures, going on a crusade or building a new cathedral. – Page 391
20. The End Of Homo Sapiens
True, we still don’t have the acumen to achieve this, but there seems to be no insurmountable technical barrier preventing us from producing superhumans. The main obstacles are the ethical and political objections that have slowed down research on humans. And no matter how convincing the ethical arguments may be, it is hard to see how they can hold back the next step for long, especially if what is at stake is the possibility of prolonging human life indefinitely, conquering incurable diseases, and upgrading our cognitive and emotional abilities. – Page 403
what do we want to become? This question, sometimes known as the Human Enhancement question, dwarfs the debates that currently preoccupy politicians, philosophers, scholars and ordinary people. – Page 413
But since we might soon be able to engineer our desires too, the real question facing us is not ‘What do we want to become?’, but ‘What do we want to want?’ Those who are not spooked by this question probably haven’t given it enough thought. – Page 414
Afterword: The Animal That Became A God
Is there anything more dangerous than dissatisfied and irresponsible gods who don’t know what they want? – Page 415
