Yuval Noah Harari Quotes

Fiction isn't bad. It is vital. Without commonly accepted stories about things like money, states or corporations, no complex human society can function. We can't play football unless everyone believes in the same made-up rules, and we can't enjoy the benefits of markets and courts without similar make-believe stories. But the stories are just tools. They should not become our goals or yardsticks. When we forget that they are mere fiction, we lose touch with reality.

There is today a division of labor between the elite and the masses. In medieval Europe aristocrats spent their money carelessly on extravagant luxuries whereas peasants lived frugally minding every penny. Today the tables have turned. The rich take great care managing their assets and investments, while the less well-heeled go into debt buying cars and televisions they don't really need.

Studying history aims to loosen the grip of the past. It enables us to turn our head this way and that, and begin to notice possibilities that our ancestors could not imagine, or didn’t want us to imagine. By observing the accidental chain of events that led us here, we realise how our very thoughts and dreams took shape — and we can begin to think and dream differently. Studying history will not tell us what to choose, but at least it gives us more options.

As far as we can tell from a purely scientific viewpoint, human life has absolutely no meaning. Humans are the outcome of blind evolutionary processes that operate without goal or purpose. Our actions are not part of some divine cosmic plan, and if planet earth were to blow up tomorrow morning, the universe would probably keep going about its business as usual. As far as we can tell at this point, human subjectivity would not be missed. Hence any meaning that people inscribe to their lives is just a delusion.

This is the paradox of historical knowledge. Knowledge that does not change behaviour is useless. But knowledge that changes behaviour loses its relevance. The more data we have and the better we understand history, the faster history alters its course, and the faster our knowledge becomes outdated.

If Marx came back to life today, he would probably urge his few remaining disciples to devote less time to reading Das Kapital and more time to studying the Internet and the human genome.

This is the best reason to learn history: not in order to predict the future, but to free yourself of the past and imagine alternative destinies. Of course this is not total freedom - we cannot avoid being shaped by the past. But some freedom is better than none.

Why is English so widespread today, and not Danish?

Success breeds ambition, and our recent achievements are now pushing humankind to set itself even more daring goals. Having secured unprecedented levels of prosperity, health and harmony, and given our past record and our current values, humanity’s next targets are likely to be immortality, happiness and divinity.

As far as we can tell, from a purely scientific viewpoint, human life has absolutely no meaning. Humans are the outcome of blind evolutionary processes that operate without goal or purpose. Our actions are not part of some divine cosmic plan, and if planet Earth were to blow up tomorrow morning, the universe would probably keep going about business as usual.

If you experience sadness without craving that the sadness go away, you continue to feel sadness, but you do not suffer from it. There can actually be richness in the sadness. If you experience joy without craving that the joy linger and intensify, you continue to feel joy without losing your peace of mind.

Knowledge that does not change behaviour is useless. But knowledge that changes behaviour quickly loses its relevance.

If you want to see philosophy in action, pay a visit to a robo-rat laboratory. A robo-rat is a run-ofthe-mill rat with a twist: scientists have implanted electrodes into the sensory and reward areas in the rat’s brain. This enables the scientists to manoeuvre the rat by remote control. After short training sessions, researchers have managed not only to make the rats turn left or right, but also to climb ladders, sniff around garbage piles, and do things that rats normally dislike, such as jumping from great heights. Armies and corporations show keen interest in the robo-rats, hoping they could prove useful in many tasks and situations. For example, robo-rats could help detect survivors trapped under collapsed buildings, locate bombs and booby traps, and map underground tunnels and caves. Animal-welfare activists have voiced concern about the suffering such experiments inflict on the rats. Professor Sanjiv Talwar of the State University of New York, one of the leading robo-rat researchers, has dismissed these concerns, arguing that the rats actually enjoy the experiments. After all, explains Talwar, the rats ‘work for pleasure’ and when the electrodes stimulate the reward centre in their brain, ‘the rat feels Nirvana’.To the best of our understanding, the rat doesn’t feel that somebody else controls her, and she doesn’t feel that she is being coerced to do something against her will. When Professor Talwar presses the remote control, the rat wants to move to the left, which is why she moves to the left. When the professor presses another switch, the rat wants to climb a ladder, which is why she climbs the ladder. After all, the rat’s desires are nothing but a pattern of firing neurons. What does it matter whether the neurons are firing because they are stimulated by other neurons, or because they are stimulated by transplanted electrodes connected to Professor Talwar’s remote control? If you asked the rat about it, she might well have told you, ‘Sure I have free will! Look, I want to turn left – and I turn left. I want to climb a ladder – and I climb a ladder. Doesn’t that prove that I have free will?

How can we distinguish what is biologically determined from what people merely try to justify through biological myths? 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 realize some possibilities while forbidding others. Biology enables women to have children – some cultures oblige women to realize this possibility. Biology enables men to enjoy sex with one another – some cultures forbid them to realize this possibility. 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 behavior, one that goes against the laws of nature, simply cannot exist.

The Theory of Relativity makes nobody angry because it doesn't contradict any of our cherished beliefs. Most people don't care an iota whether space and time are absolute or relative. If you think it is possible to bend space and time, well be my guest. ...In contrast, Darwin has deprived us of our souls. If you really understand the Theory of Evolution, you understand that there is no soul. This is a terrifying thought, not only to devote Christians and Muslims, but also to many secular people who don't hold any clear religious dogma, but nevertheless, want to believe that each human possess an eternal, individual essence that remains unchanged throughout life and can survive even death intact.

China the Communist Party still pays lip service to traditional Marxist–Leninist ideals, but in practice it is guided by Deng Xiaoping’s famous maxims that ‘development is the only hard truth’ and that ‘it doesn’t matter if a cat is black or white, so long as it catches mice’. Which means, in plain language: do anything it takes to promote economic growth, even if Marx and Lenin wouldn’t have been happy with it. In Singapore, as befits that no-nonsense city state, they followed this line of thinking even further, and pegged ministerial salaries to the national GDP. When the Singaporean economy grows, ministers get a raise, as if that is what their job is all about

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 can imagine.

Rather, when famine, plague or war break out of our control, we feel that somebody must have screwed up, we set up a commission of inquiry, and promise ourselves that next time we’ll do better.

Paradise, the capitalists promise, is right around the corner. True, mistakes have been made such as the Atlantic slave trade and the exploitation of the European working class, but we have learned our lesson and if we just wait a little longer and allow the pie to grow a little bigger, everybody will receive a fatter slice.

science says that nobody is ever made happy by getting a promotion, winning the lottery or even finding true love. People are made happy by one thing and one thing only - pleasant sensations in their bodies

Consistency is the playground of dull minds

In the 300 years of the crucifixion of Christ to the conversion of Emperor Constantine, polytheistic Roman emperors initiated no more than four general persecutions of Christians. Local administrators and governors incited some 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 capitalist and consumerist ethics are two sides of the same coin, a merger of two commandments. The supreme commandment of the rich is ‘Invest!’ The supreme commandment of the rest of us is ‘Buy!’ The capitalist–consumerist ethic is revolutionary in another respect. Most previous ethical systems presented people with a pretty tough deal. They were promised paradise, but only if they cultivated compassion and tolerance, overcame craving and anger, and restrained their selfish interests. This was too tough for most. 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. In contrast, most people today successfully live up to the capitalist–consumerist ideal. The new ethic promises paradise on condition that the rich remain greedy and spend their time making more money and that the masses give free reign to their cravings and passions and buy more and more. This is the first religion in history whose followers actually do what they are asked to do. How though do we know that we'll really get paradise in return? We've seen it on television.

There are no gods, no nations, no money and no human rights, except in our collective imagination.

When an animal is looking for something that increases its chances of survival and reproduction (e.g. food, partners or social status), the brain produces sensations of alertness and excitement, which drive the animal to make even greater efforts because they are so very agreeable. In a famous experiment scientists connected electrodes to the brains of several rats, enabling the animals to create sensations of excitement simply by pressing a pedal. When the rats were given a choice between tasty food and pressing the pedal, they preferred the pedal (much like kids preferring to play video games rather than come down to dinner). The rats pressed the pedal again and again, until they collapsed from hunger and exhaustion

During the nineteenth and twentieth centuries, as humanism gained increasing social credibility and political power, it sprouted two very different offshoots: socialist humanism, which encompassed a plethora of socialist and communist movements, and evolutionary humanism, whose most famous advocates were the Nazis. Both offshoots agreed with liberalism that human experience is the ultimate source of meaning and authority.

That’s how history unfolds. People weave a web of meaning, believe in it with all their heart, but sooner or later the web unravels, and when we look back we cannot understand how anybody could have taken it seriously.

That spectacular leap from the middle to the top had enormous consequences.Other animals at the top of the pyramid, such as lions and sharks, evolved intothat position very gradually, over millions of years. This enabled the ecosystem todevelop checks and balances that prevent lions and sharks from wreaking toomuch havoc. As lions became deadlier, so gazelles evolved to run faster, hyenas tocooperate better, and rhinoceroses to be more bad-tempered. In contrast,humankind ascended to the top so quickly that the ecosystem was not given timeto adjust. Moreover, humans themselves failed to adjust. Most top predators of theplanet are majestic creatures. Millions of years of dominion have ɹlled them withself-conɹdence. 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 fearsand anxieties over our position, which makes us doubly cruel and dangerous.Many historical calamities, from deadly wars to ecological catastrophes, haveresulted from this over-hasty jump.

In the past, censorship worked by blocking the flow of information. In the 21st century, censorship works by flooding people with irrelevant information. People just don't know what to pay attention to, and they often spend their time investigating and debating side issues.

Patriarchy has been the normal in almost all agricultural and industrial societies. ...If patriarchy in Afro-Asia resulted from some chance occurrence, why were the Aztecs and Incas patriarchal? It is far more likely that even though the precise definition of man and woman varies between cultures, there is some universal biological reason why almost all cultures valued manhood over womanhood. We do not know what this reason is; there are plenty of theories, none of the convincing.

Romantic literature often presents the individual as somebody caught in a struggle against the state and the market. Nothing could be further from the truth. The state and the market are the mother and father of the individual, and the individual can survive only thanks to them. The market provides us with work, insurance and a pension. If we want to study a profession, the government’s schools are there to teach us. If we want to open a business, the bank loans us money. If we want to build a house, a construction company builds it and the bank gives us a mortgage, in some cases subsidised or insured by the state. If violence flares up, the police protect us. If we are sick for a few days, our health insurance takes care of us. If we are debilitated for months, social security steps in. If we need around-the-clock assistance, we can go to the market and hire a nurse – usually some stranger from the other side of the world who takes care of us with the kind of devotion that we no longer expect from our own children. If we have the means, we can spend our golden years at a senior citizens’ home. The tax authorities treat us as individuals, and do not expect us to pay the neighbours’ taxes. The courts, too, see us as individuals, and never punish us for the crimes of our cousins.Not only adult men, but also women and children, are recognised as individuals. Throughout most of history, women were often seen as the property of family or community. Modern states, on the other hand, see women as individuals, enjoying economic and legal rights independently of their family and community. They may hold their own bank accounts, decide whom to marry, and even choose to divorce or live on their own.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 deal between states, markets and individuals is an uneasy one. The state and the market disagree about their mutual rights and obligations, and individuals complain that both demand too much and provide too little. In many cases individuals are exploited by markets, and states employ their armies, police forces and bureaucracies to persecute individuals instead of defending them. Yet it is amazing that this deal works at all – however imperfectly. For it breaches countless generations of human social arrangements. Millions of years of evolution have designed us to live and think as community members. Within a mere two centuries we have become alienated individuals. Nothing testifies better to the awesome power of culture.

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 effectivelyy.

fantasy gives meaning to the suffering.

Listen, Google,’ I will say, ‘both John and Paul are courting me. I like both of them, but in a different way, and it’s so hard to make up my mind. Given everything you know, what do you advise me to do?’And Google will answer: ‘Well, I know you from the day you were born. I have read all your emails, recorded all your phone calls, and know your favourite films, your DNA and the entire history of your heart. I have exact data about each date you went on, and if you want, I can show you second-by-second graphs of your heart rate, blood pressure and sugar levels whenever you went on a date with John or Paul. If necessary, I can even provide you with accurate mathematical ranking of every sexual encounter you had with either of them. And naturally enough, I know them as well as I know you. Based on all this information, on my superb algorithms, and on decades’ worth of statistics about millions of relationships – I advise you to go with John, with an 87 per cent probability of being more satisfied with him in the long run.Indeed, I know you so well that I also know you don’t like this answer. Paul is much more handsome than John, and because you give external appearances too much weight, you secretly wanted me to say “Paul”. Looks matter, of course; but not as much as you think. Your biochemical algorithms – which evolved tens of thousands of years ago in the African savannah – give looks a weight of 35 per cent in their overall rating of potential mates. My algorithms – which are based on the most up-to-date studies and statistics – say that looks have only a 14 per cent impact on the long-term success of romantic relationships. So, even though I took Paul’s looks into account, I still tell you that you would be better off with John.

This is the paradox of historical knowledge. Knowledge that does not change behaviour is useless. But knowledge that changes behaviour quickly loses its relevance.

Many call this process 'the destruction of nature.' But it's not really destruction, it's change. Nature cannot be destroyed.

Whereas the Agricultural Revolution gave rise to theist religions, the Scientific Revolution gave birth to humanist religions, in which humans replaced gods.

The currency of evolution is neither hunger nor pain, but rather copies of DNA helixes

If Kindle is upgraded with face recognition and biometric sensors, it can know what made you laugh, what made you sad and what made you angry. Soon, books will read you while you are reading them.

the crucial factor in ourconquest of the world was our ability to connect many humans to one another.

The right to the pursuit of happiness, originally envisaged as a restraint on state power, has imperceptibly morphed into the right to happiness – as if human beings have a natural right to be happy, and anything which makes us dissatisfied is a violation of our basic human rights, so the state should do something about it.

Money is 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.

Buddhism does not deny the existence of gods—they are described as powerful beings who can bring rains and victories—but they have no influence on the law that suffering arises from craving. If the mind of a person is free of all craving, no god can make him miserable. Conversely, once craving arises in a person's mind, all the gods in the universe cannot save him from suffering.

Healing is the initial justification for every upgrade.

Sapiens don’t behave according to a cold mathematical logic, but rather according to a warm social logic. We are ruled by emotions.

For thousands of years priests, rabbis and muftis explained that humans cannot overcome famine, plague and war by their own efforts. Then along came the bankers, investors and industrialists, and within 200 years managed to do exactly that.

The only thing we can try to do is to influence the direction scientists are taking. Since we might soon be able to engineer our desires too, perhaps the real questions 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.

Rather than heralding a new era of easy living, the Agricultural Revolution left farmers with lives generally more difficult and less satisfying than those of foragers. Hunter-gatherers spent their time in more stimulating and varied ways, and were less in danger of starvation and disease. The Agricultural Revolution certainly enlarged the sum total of food at the disposal of humankind, but the extra food did not translate into a better diet or more leisure. Rather, it translated into population explosions and pampered elites. The average farmer worked harder than the average forager, and got a worse diet in return. The Agricultural Revolution was history’s biggest fraud.

This is the fly in the ointment of free-market capitalism. It cannot ensure that profits are gained in a fair way, or distributed in a fair manner. On the contrary, the craving to increase profits and production blinds people to anything that might stand in the way.

When humans began cultivating the land, they thought that the extra work this required will pay off. 'Yes, we will have to work harder. But the harvest will be so bountiful! We won't have to worry any more about lean years. Our children will never go to sleep hungry.' It made sense.If you worked harder, you would have a better life. That was the plan.The first part of the plan went smoothly. People indeed worked harder. But people did not foresee that the number of children would increase, meaning that the extra wheat would have to be shared between more children.Neither did the early farmers understand that feeding children with more porridge and less breast milk would weaken their immune system, and that permanent settlements would be hotbeds for infectious diseases.They did not foresee that by increasing their dependence on a single source of food, they were actually exposing themselves even more to the depredations of drought. Nor did the farmers foresee that in good years their bulging granaries would tempt thieves and enemies, compelling them to start building walls and doing guard duty.

Humanism split into three main branches. The orthodox branch holds that each human being is a unique individual possessing a distinctive inner voice and a never-to-be-repeated string of experiences. Every human being is a singular ray of light, which illuminates the world from a different perspective, and which adds colour, depth and meaning to the universe.

After all, when ‘the Lord saw how great the wickedness of the human race had become’ He resolved to ‘wipe from the face of the earth the human race I have created – and with them the animals, the birds and the creatures that move along the ground – for I regret that I have made them’ (Genesis 6:7). The Bible thinks it is perfectly all right to destroy all animals as punishment for the crimes of Homo sapiens, as if the existence of giraffes, pelicans and ladybirds has lost all purpose if humans misbehave. The Bible could not imagine a scenario in which God repents having created Homo sapiens, wipes this sinful ape off the face of the earth, and then spends eternity enjoying the antics of ostriches, kangaroos and panda bears.

Famine, plague and war will probably continue to claim millions of victims in the coming decades. Yet they are no longer unavoidable tragedies beyond the understanding and control of a helpless humanity.

Archaic humans paid for their large brains in two ways. Firstly, they spentmore time in search of food. Secondly, their muscles atrophied. Like a governmentdiverting money from defence to education, humans diverted energy from bicepsto neurons.
