Sapiens Book Summary, Review, Notes

Sapiens by Yuval Noah Harari is an anthropological masterpiece on how humanity came to be. 

You will learn how we went from running on savannas to driving cars, how we (probably) formed religion, why we “defeated” the other six species of humans, and why gossip is so important to us. And all of this was written in a funny way with plenty of jokes and puns!

Book Title: Sapiens: A Brief History of Humankind

Date of Reading: April, 2017
Rating: 10/10

What Is Being Said In Detail:

Sapiens is divided into four major parts: The Cognitive Revolution, The Agricultural Revolution, The Unification of Humankind, and The Scientific Revolution. Each part is divided into four to six chapters that describe the idea behind the part in detail.

Part One The Cognitive Revolution.

This part explains how humans first started evolving, what set us apart from Neanderthals and other Sapiens species (there were seven types of humans!), and why we started ruling the world. The chapters in this part are:

  1. An Animal of No Significance
  2. The Tree of Knowledge
  3. A Day in the Life of Adam and Eve
  4. The Flood

Part Two The Agricultural Revolution

This part explains the transition from a hunter-gatherer society into an agricultural one. We started working way more, producing more goods, but also getting more sick and bringing in new problems into our lives. The chapters in this part are:

  1. History’s Biggest Fraud
  2. Building Pyramids
  3. Memory Overload
  4. There is No Justice in History

Part Three The Unification of Humankind

This part explains the development of different parts of the world, the emergence of culture and how that played a major role in what countries focused on. The chapters in this part are:

  1. The Arrow of History
  2. The Scent of Money
  3. Imperial Visions
  4. The Law of Religion
  5. The Secret of Success

Part Four The Scientific Revolution

This part explains why European countries started dominating the late modern era and what kind of role capitalism, Catholicism, and science played in that. The chapters in this part are:

  1. The Discovery of Ignorance
  2. The Marriage of Science and Empire
  3. The Capitalist Creed
  4. The Wheels of Industry
  5. A Permanent Revolution
  6. And They Lived Happily Ever After
  7. The End of Homo Sapiens

Most Important Keywords, Sentences, Quotes:

Part One The Cognitive Revolution

1. An Animal of No Significance

“The chimpanzees are the closest. Just 6 million years ago, a single female ape had two daughters. One became the ancestor of all chimpanzees, the other is our own grandmother.”

“As lions became deadlier, so gazelles evolved to run faster, hyenas to cooperate better, and rhinoceroses to be more bad tempered. In contrast, humankind ascended to the top so quickly that the ecosystem was not given time to adjust. 

Moreover, humans themselves failed to adjust. Most top predators of the planet are majestic creatures. Millions of years of dominion have filled them with self-confidence. Sapiens by contrast is more like a banana republic dictator. 

Having so recently been one of the underdogs of the savannah, we are full of fears and anxieties over our position, which makes us doubly cruel and dangerous. Many historical calamities, from deadly wars to ecological catastrophes, have resulted from this over-hasty jump.”

2. The Tree of Knowledge

“(In a band of fifty individuals, there are 1,225 one-on-one relationships, and countless more complex social combinations.)” 

‘The lion is the guardian spirit of our tribe.’ This ability to speak about fictions is the most unique feature of Sapiens language.”

But fiction has enabled us not merely to imagine things, but to do so collectively. We can weave common myths such as the biblical creation story, the Dreamtime myths of Aboriginal Australians, and the nationalist myths of modern states. 

Such myths give Sapiens the unprecedented ability to cooperate flexibly in large numbers. Ants and bees can also work together in huge numbers, but they do so in a very rigid manner and only with close relatives. 

Wolves and chimpanzees cooperate far more flexibly than ants, but they can do so only with small numbers of other individuals that they know intimately. Sapiens can cooperate in extremely flexible ways with countless numbers of strangers. 

That’s why Sapiens rule the world, whereas ants eat our leftovers and chimps are locked up in zoos and research laboratories.” 

“Large numbers of strangers can cooperate successfully by believing in common myths.” 

“Two Catholics who have never met can nevertheless go together on crusade or pool funds to build a hospital because they both believe that God was incarnated in human flesh and allowed Himself to be crucified to redeem our sins.” 

“Two Serbs who have never met might risk their lives to save one another because both believe in the existence of the Serbian nation, the Serbian homeland and the Serbian flag. 

Judicial systems are rooted in common legal myths. Two lawyers who have never met can nevertheless combine efforts to defend a complete stranger because they both believe in the existence of laws, justice, human rights – and the money paid out in fees.”

Yuval Noah Harari Quote: “You could never convince a monkey to give you a banana by promising him limitless bananas after death in monkey heaven.”

“Just try to imagine how difficult it would have been to create states, or churches, or legal systems if we could speak only about things that really exist, such as rivers, trees and lions.” 

“No one was lying when, in 2011, the UN demanded that the Libyan government respect the human rights of its citizens, even though the UN, Libya and human rights are all figments of our fertile imaginations.” 

“myths can change rapidly. In 1789 the French population switched almost overnight from believing in the myth of the divine right of kings to believing in the myth of the sovereignty of the people.” 

“The immense diversity of imagined realities that Sapiens invented, and the resulting diversity of behaviour patterns, are the main components of what we call ‘cultures’. Once cultures appeared, they never ceased to change and develop, and these unstoppable alterations are what we call ‘history’.” 

3. A Day in the Life of Adam and Eve

“Rather, foragers lived in communes devoid of private property, monogamous relationships and even fatherhood. In such a band, a woman could have sex and form intimate bonds with several men (and women) simultaneously, and all of the band’s adults cooperated in parenting its children. 

Since no man knew definitively which of the children were his, men showed equal concern for all youngsters.” 

“sperm in a woman’s womb. A good mother will make a point of having sex with several different men, especially when she is pregnant, so that her child will enjoy the qualities (and paternal care) not merely of the best hunter, but also of the best storyteller, the strongest warrior and the most considerate lover.”

Yuval Noah Harari Quote: “Consistency is the playground of dull minds.”

“This, after all, was one of the main legacies of the Cognitive Revolution. 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.”

“Ancient foragers also suffered less from infectious diseases. Most of the infectious diseases that have plagued agricultural and industrial societies (such as smallpox, measles and tuberculosis) originated in domesticated animals and were transferred to humans only after the Agricultural Revolution.

4. The Flood

“Andean mountain valleys or the open pampas of Argentina. And all this happened in a mere millennium or two! By 10,000 BC, humans already inhabited the most southern point in America, the island of Tierra del Fuego at the continent’s southern tip. 

The human blitzkrieg across America testifies to the incomparable ingenuity and the unsurpassed adaptability of Homo sapiens. No other animal had ever moved into such a huge variety of radically different habitats so quickly, everywhere using virtually the same genes.” 

“Within 2,000 years of the Sapiens arrival, most of these unique species were gone. According to current estimates, within that short interval, North America lost thirty-four out of its forty-seven genera of large mammals. South America lost fifty out of sixty. 

The sabre-tooth cats, after flourishing for more than 30 million years, disappeared, and so did the giant ground sloths, the oversized lions, native American horses, native American camels, the giant rodents and the mammoths.” 

Part Two The Agricultural Revolution

5. History’s Biggest Fraud

“All this changed about 10,000 years ago, when Sapiens began to devote almost all their time and effort to manipulating the lives of a few animal and plant species. 

From sunrise to sunset humans sowed seeds, watered plants, plucked weeds from the ground and led sheep to prime pastures. This work, they thought, would provide them with more fruit, grain and meat. It was a revolution in the way humans lived – the Agricultural Revolution.” 

“The average farmer worked harder than the average forager, and got a worse diet in return. The Agricultural Revolution was history’s biggest fraud.”

“At first they might have camped for four weeks during the harvest. A generation later, as wheat plants multiplied and spread, the harvest camp might have lasted for five weeks, then six, and finally it became a permanent village. 

Evidence of such settlements has been discovered throughout the Middle East, particularly in the Levant, where the Natufian culture flourished from 12,500 to 9500 BC.” 

Yuval Noah Harari Quote: “Money is the most universal and most efficient system of mutual trust ever devised.”

“We have enough documents, letters and memoirs to prove that World War Two was not caused by food shortages or demographic pressures. 

But we have no documents from the Natufian culture, so when dealing with ancient periods the materialist school reigns supreme. It is difficult to prove that preliterate people were motivated by faith rather than economic necessity.” 

“Yet as they studied Göbekli Tepe, they discovered an amazing fact. Stonehenge dates to 2500 BC, and was built by a developed agricultural society. The structures at Göbekli Tepe are dated to about 9500 BC, and all available evidence indicates that they were built by hunter-gatherers.”

“The only way to build Göbekli Tepe was for thousands of foragers belonging to different bands and tribes to cooperate over an extended period of time. Only a sophisticated religious or ideological system could sustain such efforts.” 

6. Building Pyramids

“The French Revolution was spearheaded by affluent lawyers, not by famished peasants. The Roman Republic reached the height of its power in the first century BC, when treasure fleets from throughout the Mediterranean enriched the Romans beyond their ancestors’ wildest dreams.” 

“But that turned out to be wrong. Myths, it transpired, are stronger than anyone could have imagined. When the Agricultural Revolution opened opportunities for the creation of crowded cities and mighty empires, people invented stories about great gods, motherlands and joint stock companies to provide the needed social links. 

While human evolution was crawling at its usual snail’s pace, the human imagination was building astounding networks of mass cooperation, unlike any other ever seen on earth.” 

The social norms that sustained them were based neither on ingrained instincts nor on personal acquaintances, but rather on belief in shared myths.”

“known myths of history: the Code of Hammurabi of c.1776 BC, which served as a cooperation manual for hundreds of thousands of ancient Babylonians; and the American Declaration of Independence of 1776 AD, which today still serves as a cooperation manual for hundreds of millions of modern Americans.” 

“hundred soldiers – far more cheaply and effectively. Moreover, no matter how efficient bayonets are, somebody must wield them. Why should the soldiers, jailors, judges and police maintain an imagined order in which they do not believe? Of all human collective activities, the one most difficult to organise is violence. 

To say that a social order is maintained by military force immediately raises the question: what maintains the military order? It is impossible to organise an army solely by coercion. At least some of the commanders and soldiers must truly believe in something, be it God, honour, motherland, manhood or money.”

Yuval Noah Harari Quote: “Each year the US population spends more money on diets than the amount needed to feed all the hungry people in the rest of the world.”

“This is why cynics don’t build empires and why an imagined order can be maintained only if large segments of the population – and in particular large segments of the elite and the security forces – truly believe in it. 

Christianity would not have lasted 2,000 years if the majority of bishops and priests failed to believe in Christ. American democracy would not have lasted almost 250 years if the majority of presidents and congressmen failed to believe in human rights. 

The modern economic system would not have lasted a single day if the majority of investors and bankers failed to believe in capitalism.” 

“In order to understand this, we need to understand the difference between ‘objective’, ‘subjective’, and ‘intersubjective’.”

“An objective phenomenon exists independently of human consciousness and human beliefs.”

“The subjective is something that exists depending on the consciousness and beliefs of a single individual.”

“The inter-subjective is something that exists within the communication network linking the subjective consciousness of many individuals.” 

7. Memory Overload

“‘Kushim!’ It is telling that the first recorded name in history belongs to an accountant, rather than a prophet, a poet or a great conqueror.”

8. There is No Justice in History

“The sun was created from the Purusa’s eye, the moon from the Purusa’s brain, the Brahmins (priests) from its mouth, the Kshatriyas (warriors) from its arms, the Vaishyas (peasants and merchants) from its thighs, and the Shudras (servants) from its legs. 

Accept this explanation and the sociopolitical differences between Brahmins and Shudras are as natural and eternal as the differences between the sun and the moon.” 

“A good rule of thumb is ‘Biology enables, Culture forbids.’ Biology is willing to tolerate a very wide spectrum of possibilities. It’s culture that obliges people to realise some possibilities while forbidding others.

Biology enables women to have children – some cultures oblige women to realise this possibility. Biology enables men to enjoy sex with one another – some cultures forbid them to realise this possibility.” 

“In truth, our concepts ‘natural’ and ‘unnatural’ are taken not from biology, but from Christian theology.” 

“In organised crime, the big boss is not necessarily the strongest man. He is often an older man who very rarely uses his own fists; he gets younger and fitter men to do the dirty jobs for him. 

A guy who thinks that the way to take over the syndicate is to beat up the don is unlikely to live long enough to learn from his mistake.” 

“In fact, in numerous societies throughout history, the top officers did not work their way up from the rank of private. Aristocrats, the wealthy and the educated were automatically assigned officer rank and never served a day in the ranks.” 

“The militarily incompetent Augustus succeeded in establishing a stable imperial regime, achieving something that eluded both Julius Caesar and Alexander the Great, who were much better generals.”

“How did it happen that in the one species whose success depends above all on cooperation, individuals who are supposedly less cooperative (men) control individuals who are supposedly more cooperative (women)? At present, we have no good answer. 

Maybe the common assumptions are just wrong. Maybe males of the species Homo sapiens are characterised not by physical strength, aggressiveness and competitiveness, but rather by superior social skills and a greater tendency to cooperate. We just don’t know.”

 

Part Three The Unification of Humankind

9. The Arrow of History

“Myths and fictions accustomed people, nearly from the moment of birth, to think in certain ways, to behave in accordance with certain standards, to want certain things, and to observe certain rules. 

They thereby created artificial instincts that enabled millions of strangers to cooperate effectively. This network of artificial instincts is called ‘culture’.”

“America and Europe, too, were separate worlds for most of their histories. In 378, the Roman AD emperor Valence was defeated and killed by the Goths at the battle of Adrianople. 

In the same year, King Chak Tok Ich’aak of Tikal was defeated and killed by the army of Teotihuacan. (Tikal was an important Mayan city state, while Teotihuacan was then the largest city in America, with almost 250,000 inhabitants – of the same order of magnitude as its contemporary, Rome.) 

There was absolutely no connection between the defeat of Rome and the rise of Teotihuacan. Rome might just as well have been located on Mars, and Teotihuacan on Venus.” 

Yuval Noah Harari Quote: “There are no gods, no nations, no money and no human rights, except in our collective imagination.”

“One of the most interesting examples of this globalisation is ‘ethnic’ cuisine. 

In an Italian restaurant we expect to find spaghetti in tomato sauce; in Polish and Irish restaurants lots of potatoes; in an Argentinian restaurant we can choose between dozens of kinds of beefsteaks; in an Indian restaurant hot chillies are incorporated into just about everything; and the highlight at any Swiss café is thick hot chocolate under an alp of whipped cream. 

But none of these foods is native to those nations. Tomatoes, chilli peppers and cocoa are all Mexican in origin; they reached Europe and Asia only after the Spaniards conquered Mexico.”

10. The Scent of Money

“In a barter economy, every day the shoemaker and the apple grower will have to learn the relative prices of dozens of commodities. If one hundred different commodities are traded in the market, then buyers and sellers will have to know 4,950 different exchange rates. 

And if 1,000 different commodities are traded, buyers and sellers must juggle 499,500 different exchange rates! How do you figure it out?” 

“In fact, even today coins and banknotes are a rare form of money. The sum total of money in the 7 world is about $60 trillion, yet the sum total of coins and banknotes is less than $6 trillion. More than 90 per cent of all money – more than $50 trillion appearing in our accounts – exists only on computer servers.” 

“Money also frees apple experts from the need to search out apple-craving shoemakers, because everyone always wants money. 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. The shoemaker will always be happy to take your money, because no matter what he really wants – apples, goats or a divorce – he can get it in exchange for money.” 

“In other words, money isn’t a material reality – it is a psychological construct.” 

“People are willing to do such things when they trust the figments of their collective imagination. Trust is the raw material from which all types of money are minted.” 

“money is the most universal and most efficient system of mutual trust ever devised.”

“Merchants travelling between India and the Mediterranean would notice the difference in the value of gold. In order to make a profit, they would buy gold cheaply in India and sell it dearly in the Mediterranean. 

Consequently, the demand for gold in India would skyrocket, as would its value. At the same time the Mediterranean would experience an influx of gold, whose value would consequently drop. Within a short time the value of gold in India and the Mediterranean would be quite similar. 

The mere fact that Mediterranean people believed in gold would cause Indians to start believing in it as well. Even if Indians still had no real use for gold, the fact that Mediterranean people wanted it would be enough to make the Indians value it.”

11. Imperial Visions

“An empire is a political order with two important characteristics. First, to qualify for that designation you have to rule over a significant number of distinct peoples, each possessing a different cultural identity and a separate territory. 

How many peoples exactly? Two or three is not sufficient. Twenty or thirty is plenty. The imperial threshold passes somewhere in between. 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.” 

12. The Law of Religion

“Today religion is often considered a source of discrimination, disagreement and disunion. 

Yet, in fact, religion has been the third great unifier of humankind, alongside money and empires. Since all social orders and hierarchies are imagined, they are all fragile, and the larger the society, the more fragile it is.”

“Religion can thus be defined as a system of human norms and values that is founded on a belief in a superhuman order.

“This, however, created a big problem. Farmers may have desired absolute control of their sheep, but they knew perfectly well that their control was limited. 

They could lock the sheep in pens, castrate rams and selectively breed ewes, yet they could not ensure that the ewes conceived and gave birth to healthy lambs, nor could they prevent the eruption of deadly epidemics. How then to safeguard the fecundity of the flocks? 

A leading theory about the origin of the gods argues that gods gained importance because they offered a solution to this problem. Gods such as the fertility goddess, the sky god and the god of medicine took centre stage when plants and animals lost their ability to speak, and the gods’ main role was to mediate between humans and the mute plants and animals.” 

Yuval Noah Harari Quote: “A meaningful life can be extremely satisfying even in the midst of hardship, whereas a meaningless life is a terrible ordeal no matter how comfortable it is.”

“anti-Christian violence of their own. 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. 

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.”

“The religious wars between Catholics and Protestants that swept Europe in the sixteenth and seventeenth centuries are particularly notorious. All those involved accepted Christ’s divinity and His gospel of compassion and love.”

“and opening the gates of heaven to all those who professed faith in Him. Catholics maintained that faith, while essential, was not enough. To enter heaven, believers had to participate in church rituals and do good deeds. Protestants refused to accept this, arguing that this quid pro quo belittles God’s greatness and love. 

Whoever thinks that entry to heaven depends upon his or her own good deeds magnifies his own importance, and implies that Christ’s suffering on the cross and God’s love for humankind are not enough.”

“On 23 August 1572, French Catholics who stressed the importance of good deeds attacked communities of French Protestants who highlighted God’s love for humankind. In this attack, the St Bartholomew’s Day Massacre, between 5,000 and 10,000 Protestants were slaughtered in less than twenty-four hours. 

When the pope in Rome heard the news from France, he was so overcome by joy that he organised festive prayers to celebrate the occasion and commissioned Giorgio Vasari to decorate one of the Vatican’s rooms with a fresco of the massacre (the room is currently off-limits to visitors). 

More Christians were killed by fellow Christians in those twenty four hours than by the polytheistic Roman Empire throughout its entire existence.” 

“The first principle of monotheist religions is ‘God exists. What does He want from me?’ The first principle of Buddhism is ‘Suffering exists. How do I escape it?”

“The modern age has witnessed the rise of a number of new natural law religions, such as liberalism, Communism, capitalism, nationalism and Nazism. These creeds do not like to be called religions, and refer to themselves as ideologies. But this is just a semantic exercise. 

If a religion is a system of human norms and values that is founded on belief in a superhuman order, then Soviet Communism was no less a religion than Islam.” 

“Biologists have since debunked Nazi racial theory. In particular, genetic research conducted after 1945 has demonstrated that the differences between the various human lineages are far smaller than the Nazis postulated. 

But these conclusions are relatively new. Given the state of scientific knowledge in 1933, Nazi beliefs were hardly outside the pale. The existence of different human races, the superiority of the white race, and the need to protect and cultivate this superior race were widely held beliefs among most Western elites.”

13. The Secret of Success

“For example, studying how Europeans came to dominate Africans enables us to realise that there is nothing natural or inevitable about the racial hierarchy, and that the world might well be arranged differently.”

“A cultural idea – such as belief in Christian heaven above the clouds or Communist paradise here on earth – can compel a human to dedicate his or her life to spreading that idea, even at the price of death. The human dies, but the idea spreads. 

According to this approach, cultures are not conspiracies concocted by some people in order to take advantage of others (as Marxists tend to think). Rather, cultures are mental parasites that emerge accidentally, and thereafter take advantage of all people infected by them.”

“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’. 

Successful cultures are those that excel in reproducing their memes, irrespective of the costs and benefits to their human hosts.” 

“When Pakistan enlarges its navy, India counters. At the end of the process, the balance of power may remain much as it was, but meanwhile billions of dollars that could have been invested in education or health are spent on weapons.” 

“No matter what you call it – game theory, postmodernism or memetics – the dynamics of history are not directed towards enhancing human well-being. 

There is no basis for thinking that the most successful cultures in history are necessarily the best ones for Homo sapiens. Like evolution, history disregards the happiness of individual organisms. And individual humans, for their part, are usually far too ignorant and weak to influence the course of history to their own advantage.”

Part Four The Scientific Revolution

14. The Discovery of Ignorance

“In 1500, humanity consumed about 13 trillion calories of energy per day. Today, we consume 1,500 trillion calories a day. (Take a second look at those figures – human population has increased fourteen-fold, production 240-fold, and energy consumption 115-fold.) 

Suppose a single modern battleship got transported back to Columbus’ time. In a matter of seconds it could make driftwood out of the Niña, Pinta and Santa Maria and then sink the navies of every great world power of the time without sustaining a scratch. 

Five modern freighters could have taken onboard all the cargo borne by the whole world’s merchant fleets. A modern computer could easily store every word and number in all the codex books and scrolls in every single medieval library with room to spare. Any large bank today holds more money than all the world’s premodern kingdoms put together.”

“In 1873, Jules Verne could imagine that Phileas Fogg, a wealthy British adventurer, might just be able to make it around the world in eighty days. Today anyone with a middle-class income can safely and easily circumnavigate the globe in just forty-eight hours.”

“Muhammad began his religious career by condemning his fellow Arabs for living in ignorance of the divine truth. Yet Muhammad himself very quickly began to argue that he knew the full truth, and his followers began calling him ‘The Seal of the Prophets’. Henceforth, there was no need of revelations beyond those given to Muhammad.”

“Modern-day science is a unique tradition of knowledge, inasmuch as it openly admits collective ignorance regarding the most important questions. Darwin never argued that he was ‘The Seal of the Biologists’, and that he had solved the riddle of life once and for all. 

After centuries of extensive scientific research, biologists admit that they still don’t have any good explanation for how brains produce consciousness. Physicists admit that they don’t know what caused the Big Bang, or how to reconcile quantum mechanics with the theory of general relativity.”

“Henceforth, anyone who wished to understand and predict the movement of a cannonball or a planet simply had to make measurements of the object’s mass, direction and acceleration, and the forces acting on it. 

By inserting these numbers into Newton’s equations, the future position of the object could be predicted. It worked like magic. Only around the end of the nineteenth century did scientists come across a few observations that did not fit well with Newton’s laws, and these led to the next revolutions in physics – the theory of relativity and quantum mechanics.”

“The real test of ‘knowledge’ is not whether it is true, but whether it empowers us.”

“The real test is utility. A theory that enables us to do new things constitutes knowledge.

“If the legions of Scipio Aemilianus – the general who levelled Carthage and defeated the Numantians in the second century – had suddenly popped up 500 years later in the BC age of Constantine the Great, Scipio would have had a fair chance of beating Constantine. 

Now imagine what would happen to a general from a few centuries back – say Napoleon – if he led his troops against a modern armoured brigade. Napoleon was a brilliant tactician, and his men were crack professionals, but their skills would be useless in the face of modern weaponry.”

“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).” 

“Christopher Columbus and Charles Darwin. If these particular geniuses had never been born, their insights would probably have occurred to others. But if the proper funding were unavailable, no intellectual brilliance could have compensated for that. 

If Darwin had never been born, for example, we’d today attribute the theory of evolution to Alfred Russel Wallace, who came up with the idea of evolution via natural selection independently of Darwin and just a few years later.”

15. The Marriage of Science and Empire

“Only at the end of the fifteenth century did Europe become a hothouse of important military, political, economic and cultural developments. 

Between 1500 and 1750, western Europe gained momentum and became master of the ‘Outer World’, meaning the two American continents and the oceans. 

Yet even then Europe was no match for the great powers of Asia. Europeans managed to conquer America and gain supremacy at sea mainly because the Asiatic powers showed little interest in them. 

The early modern era was a golden age for the Ottoman Empire in the Mediterranean, the Safavid Empire in Persia, the Mughal Empire in India, and the Chinese Ming and Qing dynasties. 

They expanded their territories significantly and enjoyed unprecedented demographic and economic growth. In 1775 Asia accounted for 80 per cent of the world economy. 

The combined economies of India and China alone represented two-thirds of global production. In comparison, Europe was an economic dwarf.” 

“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.”

 

“What forged the historical bond between modern science and European imperialism? Technology was an important factor in the nineteenth and twentieth centuries, but in the early modern era it was of limited importance. 

The key factor was that the plant-seeking botanist and the colony-seeking naval officer shared a similar mindset. Both scientist and conqueror began by admitting ignorance – they both said, ‘I don’t know what’s out there.’ 

They both felt compelled to go out and make new discoveries. And they both hoped the new knowledge thus acquired would make them masters of the world.” 

Yuval Noah Harari Quote: “Hierarchies serve an important function. They enable complete strangers to know how to treat one another without wasting the time and energy needed to become personally acquainted.”

“As time went by, the conquest of knowledge and the conquest of territory became ever more tightly intertwined. 

In the eighteenth and nineteenth centuries, almost every important military expedition that left Europe for distant lands had on board scientists who set out not to fight but to make scientific discoveries. 

When Napoleon invaded Egypt in 1798, he took 165 scholars with him. Among other things, they founded an entirely new discipline, Egyptology, and made important contributions to the study of religion, linguistics and botany.”

“The Zheng He expeditions prove that Europe did not enjoy an outstanding technological edge. What made Europeans exceptional was their unparalleled and insatiable ambition to explore and conquer

Although they might have had the ability, the Romans never attempted to conquer India or Scandinavia, the Persians never attempted to conquer Madagascar or Spain, and the Chinese never attempted to conquer Indonesia or Africa.” 

“For 300 years, Europeans enjoyed undisputed mastery in America and Oceania, in the Atlantic and the Pacific. The only significant struggles in those regions were between different European powers. 

The wealth and resources accumulated by the Europeans eventually enabled them to invade Asia too, defeat its empires, and divide it among themselves. When the Ottomans, Persians, Indians and Chinese woke up and began paying attention, it was too late.”

“After William Jones argued that all Indo-European languages descend from a single ancient language many scholars were eager to discover who the speakers of that language had been. 

They noticed that the earliest Sanskrit speakers, who had invaded India from Central Asia more than 3,000 years ago, had called themselves Arya. The speakers of the earliest Persian language called themselves Airiia. 

European scholars consequently surmised that the people who spoke the primordial language that gave birth to both Sanskrit and Persian (as well as to Greek, Latin, Gothic and Celtic) must have called themselves Aryans. 

Could it be a coincidence that those who founded the magnificent Indian, Persian, Greek and Roman civilisations were all Aryans?”

16. The Capitalist Creed

“Banks are allowed to loan $10 for every dollar they actually possess, which means that 90 per cent of all the money in our bank accounts is not covered by actual coins and notes. 

If all of the account holders at Barclays Bank suddenly demand their money, Barclays will promptly collapse (unless the government steps in to save it). The same is true of Lloyds, Deutsche Bank, Citibank, and all other banks in the world.” 

“Then came the Scientific Revolution and the idea of progress. The idea of progress is built on the notion that if we admit our ignorance and invest resources in research, things can improve. This idea was soon translated into economic terms.” 

“This may not strike you as very original, because we all live in a capitalist world that takes Smith’s argument for granted. We hear variations on this theme every day in the news. 

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.” 

“Credit ratings indicate the probability that a country will pay its debts. In addition to purely economic data, they take into account political, social and even cultural factors. 

An oil-rich country cursed with a despotic government, endemic warfare and a corrupt judicial system will usually receive a low credit rating. As a result, it is likely to remain relatively poor since it will not be able to raise the necessary capital to make the most of its oil bounty.”

“Even worse, greedy bosses might curtail the workers’ freedom of movement through debt peonage or slavery. 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.”

“The slave trade was not controlled by any state or government. It was a purely economic enterprise, organised and financed by the free market according to the laws of supply and demand. 

Private slave-trading companies sold shares on the Amsterdam, London and Paris stock exchanges. Middle-class Europeans looking for a good investment bought these shares. Relying on this money, the companies bought ships, hired sailors and soldiers, purchased slaves in Africa, and transported them to America. 

There they sold the slaves to the plantation owners, using the proceeds to purchase plantation products such as sugar, cocoa, coffee, tobacco, cotton and rum. They returned to Europe, sold the sugar and cotton for a good price, and then sailed to Africa to begin another round. 

The shareholders were very pleased with this arrangement.Throughout the eighteenth century the yield on slave-trade investments was about 6 per cent a year – they were extremely profitable, as any modern consultant would be quick to admit.”

“Within a short time the humanitarian organisation became a business enterprise whose real aim was growth and profit. The schools and hospitals were forgotten, and the Congo basin was instead filled with mines and plantations, run by mostly Belgian officials who ruthlessly exploited the local population. 

The rubber industry was particularly notorious. Rubber was fast becoming an industrial staple, and rubber export was the Congo’s most important source of income. The African villagers who collected the rubber were required to provide higher and higher quotas. 

Those who failed to deliver their quota were punished brutally for their ‘laziness’. Their arms were chopped off and occasionally entire villages were massacred. 

According to the most moderate estimates, between 1885 and 1908 the pursuit of growth and profits cost the lives of 6 million individuals (at least 20 percent of the Congo’s population). Some estimates reach up to 10 million deaths.” 

17. The Wheels of Industry

“Six hundred years passed between the moment Chinese alchemists discovered gunpowder and the moment Turkish cannon pulverised the walls of Constantinople. 

Only forty years passed between the moment Einstein determined that any kind of mass could be converted into energy – that’s what E = mc² means – and the moment atom bombs obliterated Hiroshima and Nagasaki and nuclear power stations mushroomed all over the globe.”

“During World War One, Germany was placed under blockade and suffered severe shortages of raw materials, in particular saltpetre, an essential ingredient in gunpowder and other explosives. 

The most important saltpetre deposits were in Chile and India; there were none at all in Germany. True, saltpetre could be replaced by ammonia, but that was expensive to produce as well. Luckily for the Germans, one of their fellow citizens, a Jewish chemist named Fritz Haber, had discovered in 1908 a process for producing ammonia literally out of thin air. 

When war broke out, the Germans used Haber’s discovery to commence industrial production of explosives using air as a raw material. Some scholars believe that if it hadn’t been for Haber’s discovery, Germany would have been forced to surrender long before November 1918. 

The discovery won Haber (who during the war also pioneered the use of poison gas in battle) a Nobel Prize in 1918. In chemistry, not in peace.”

“From an objective perspective, this calf no longer needs either maternal bonding or playmates in order to survive and reproduce. But from a subjective perspective, the calf still feels a very strong urge to bond with her mother and to play with other calves. 

If these urges are not fulfilled, the calf suffers greatly. This is the basic lesson of evolutionary psychology: a need shaped in the wild continues to be felt subjectively even if it is no longer really necessary for survival and reproduction.”

“Today in the United States, only 2 percent of the population makes a living from agriculture, yet this 2 per cent produces enough not only to feed the entire US population, but also to export surpluses to the rest of the world.”

18. A Permanent Revolution

“life of most humans ran its course within three ancient frames: the nuclear family, the extended family and the local intimate community.*” 

“The community offered help on the basis of local traditions and an economy of favours, which often differed greatly from the supply and demand laws of the free market. 

In an old fashioned medieval community, when my neighbour was in need, I helped build his hut and guard his sheep, without expecting any payment in return. 

When I was in need, my neighbour returned the favour. At the same time, the local potentate might have drafted all of us villagers to construct his castle without paying us a penny.”

“In the Chinese Ming Empire (1368-1644), the population was organised into the baojia system. Ten families were grouped to form a jia, and ten jia constituted a bao. 

When a member of a bao commited a crime, other bao members could be punished for it, in particular the bao elders. Taxes too were levied on the bao, and it was the responsibility of the bao elders rather than of the state officials to assess the situation of each family and determine the amount of tax it should pay. 

From the empire’s perspective, this system had a huge advantage. Instead of maintaining thousands of revenue officials and tax collectors, who would have to monitor the earnings and expenses of every family, these tasks were left to the community elders. 

The elders knew how much each villager was worth and they could usually enforce tax payments without involving the imperial army.” 

“But the liberation of the individual comes at a cost. Many of us now bewail the loss of strong families and communities and feel alienated and threatened by the power the impersonal state and market wield over our lives. 

States and markets composed of alienated individuals can intervene in the lives of their members much more easily than states and markets composed of strong families and communities

When neighbours in a high-rise apartment building cannot even agree on how much to pay their janitor, how can we expect them to resist the state?”

 

“The two most important examples for the rise of such imagined communities are the nation and the consumer tribe. The nation is the imagined community of the state. 

The consumer tribe is the imagined community of the market. Both are imagined communities because it is impossible for all customers in a market or for all members of a nation really to know one another the way villagers knew one another in the past. 

No German can intimately know the other 80 million members of the German nation, or the other 500 million customers inhabiting the European Common Market (which evolved first into the European Community and finally became the European Union).”

“If I bake a cake from flour, oil and sugar, all of which have been sitting in my pantry for the past two months, it does not mean that the cake itself is two months old.” 

“It now exists in a state of permanent flux. When we speak of modern revolutions we tend to think of 1789 (the French Revolution), 1848 (the liberal revolutions) or 1917 (the Russian Revolution). 

But the fact is that, these days, every year is revolutionary. Today, even a thirty-year-old can honestly tell disbelieving teenagers, ‘When I was young, the world was completely different.’ 

The Internet, for example, came into wide usage only in the early 1990s, hardly twenty years ago. Today we cannot imagine the world without it.”

“The figures for 2002 are even more surprising. Out of 57 million dead, only 172,000 people died in war and 569,000 died of violent crime (a total of 741,000 victims of human violence). 

In contrast, 5 873,000 people committed suicide. It turns out that in the year following the 9/11 attacks, despite all the talk of terrorism and war, the average person was more likely to kill himself than to be killed by a terrorist, a soldier or a drug dealer.”

“There is a positive feedback loop between all these four factors. The threat of nuclear holocaust fosters pacifism; when pacifism spreads, war recedes and trade flourishes; and trade increases both the profits of peace and the costs of war. 

Over time, this feedback loop creates another obstacle tower, which may ultimately prove the most important of all. The tightening web of international connections erodes the independence of most countries, lessening the chance that any one of them might single-handedly let slip the dogs of war.”

19. And They Lived Happily Ever After

“Nationalists believe that political self-determination is essential for our happiness. Communists postulate that everyone would be blissful under the dictatorship of the proletariat. 

Capitalists maintain that only the free market can ensure the greatest happiness of the greatest number, by creating economic growth and material abundance and by teaching people to be self-reliant and enterprising.”

“In recent decades, psychologists and biologists have taken up the challenge of studying scientifically what really makes people happy. Is it money, family, genetics or perhaps virtue? The first step is to define what is to be measured. 

The generally accepted definition of happiness is ‘subjective well-being’. Happiness, according to this view, is something I feel inside myself, a sense of either immediate pleasure or long-term contentment with the way my life is going. 

If it’s something felt inside, how can it be measured from outside? Presumably, we can do so by asking people to tell us how they feel. So psychologists or biologists who want to assess how happy people feel give them questionnaires to fill out and tally the results.” 

“One interesting conclusion is that money does indeed bring happiness. But only up to a point, and beyond that point it has little significance.”

“So maybe Third World discontent is fomented not merely by poverty, disease, corruption and political oppression but also by mere exposure to First World standards.” 

“That’s one option. Another is that the findings demonstrate that happiness is not the surplus of pleasant over unpleasant moments. Rather, happiness consists in seeing one’s life in its entirety as meaningful and worthwhile.”

“The Buddhist position is particularly interesting. Buddhism has assigned the question of happiness more importance than perhaps any other human creed. 

For 2,500 years, Buddhists have systematically studied the essence and causes of happiness, which is why there is a growing interest among the scientific community both in their philosophy and their meditation practices.” 

“In meditation, you are supposed to closely observe your mind and body, witness the ceaseless arising and passing of all your feelings, and realise how pointless it is to pursue them. 

When the pursuit stops, the mind becomes very relaxed, clear and satisfied. All kinds of feelings go on arising and passing – joy, anger, boredom, lust – but once you stop craving particular feelings, you can just accept them for what they are. 

You live in the present moment instead of fantasising about what might have been.” 

“Buddha agreed with modern biology and New Age movements that happiness is independent of external conditions. Yet his more important and far more profound insight was that true happiness is also independent of our inner feelings

Indeed, the more significance we give our feelings, the more we crave them, and the more we suffer. Buddha’s recommendation was to stop not only the pursuit of external achievements, but also the pursuit of inner feelings.”

20. The End of Homo Sapiens

“Retina Implant, a government-sponsored German company, is developing a retinal prosthesis that may allow blind people to gain partial vision. It involves implanting a small microchip inside the patient’s eye. 

Photocells absorb light falling on the eye and transform it into electrical energy, which stimulates the intact nerve cells in the retina. The nervous impulses from these cells stimulate the brain, where they are translated into sight. 

At present the technology allows patients to orientate themselves in space, identify letters, and even recognise faces.”

“Mapping the first human genome required fifteen years and $3 billion. Today you can map a person’s DNA within a few weeks and at the cost of a few hundred dollars. 

The era of personalised medicine – medicine that matches treatment to DNA – has begun. The family doctor could soon tell you with greater certainty that you face high risks of liver cancer, whereas you needn’t worry too much about heart attacks. 

She could determine that a popular medication that helps 92 per cent of people is useless to you, and you should instead take another pill, fatal to many people but just right for you. The road to near-perfect medicine stands before us.”

“When the nuclear age erupted in the 1940s, many forecasts were made about the future nuclear world of the year 2000. 

When sputnik and Apollo II fired the imagination of the world, everyone began predicting that by the end of the century, people would be living in space colonies on Mars and Pluto. Few of these forecasts came true. On the other hand, nobody foresaw the Internet.” 

“And yet the great debates of history are important because at least the first generation of these gods would be shaped by the cultural ideas of their human designers. 

Would they be created in the image of capitalism, of Islam, or of feminism? The answer to this question might send them careening in entirely different directions.”

How I’ve Implemented The Ideas From The Book

This isn’t a practical, how-to book: it’s a theoretical masterpiece. Sapiens makes you think about the fundamentals of our society and how they’re standing on shaky legs such as common myths! 

The biggest thing for me was to start looking at things as they truly are. A limited liability company exists as a legal fiction, and as Marcus Aurelius said, “wine is just fermented grapes and meat is just a dead animal.”

One Small Actionable Step You Can Do

Sapiens emphasizes the importance of telling stories to unite people around common ideas. A small thing you can do is to practice telling better stories (start with your friends and family).
