Yuval Noah Harari Quotes

Science needs more than just research to make progress. It depends on the mutual reinforcement of science, politics and economics.

This fact has contributed greatly both to humankind’s extraordinary social abilities and to its unique social problems. Lone mothers could hardly forage enough food for their offspring and themselves with needy children in tow. Raising children required constant help from other family members and neighbours. It takes a tribe to raise a human. Evolution thus favoured those capable of forming strong social ties. In addition, since humans are born underdeveloped, they can be educated and socialised to a far greater extent than any other animal. Most mammals emerge from the womb like glazed earthenware emerging from a kiln – any attempt at remoulding will only scratch or break them. 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. We assume that a large brain, the use of

In the economic sphere too, the ability to hold a hammer or press a button is becoming less valuable than before. In the past, there were many things only humans could do. But now robots and computers are catching up, and may soon outperform humans in most tasks. True, computers function very differently from humans, and it seems unlikely that computers will become humanlike any time soon. In particular, it doesn’t seem that computers are about to gain consciousness, and to start experiencing emotions and sensations. Over the last decades there has been an immense advance in computer intelligence, but there has been exactly zero advance in computer consciousness. As far as we know, computers in 2016 are no more conscious than their prototypes in the 1950s. However, we are on the brink of a momentous revolution. Humans are in danger of losing their value, because intelligence is decoupling from consciousness.
Until today, high intelligence always went hand in hand with a developed consciousness. Only conscious beings could perform tasks that required a lot of intelligence, such as playing chess, driving cars, diagnosing diseases or identifying terrorists. However, we are now developing new types of non-conscious intelligence that can perform such tasks far better than humans. For all these tasks are based on pattern recognition, and non-conscious algorithms may soon excel human consciousness in recognising patterns. This raises a novel question: which of the two is really important, intelligence or consciousness? As long as they went hand in hand, debating their relative value was just a pastime for philosophers. But in the twenty-first century, this is becoming an urgent political and economic issue. And it is sobering to realise that, at least for armies and corporations, the answer is straightforward: intelligence is mandatory but consciousness is optional.

In the ceremony of Mass, the priest takes a piece of bread and a glass of wine and proclaims that the bread is Christ’s flesh, the wine is Christ’s blood, and by eating and drinking them the faithful attain communion with Christ. What could be more real than actually tasting Christ in your mouth? Traditionally, the priest made these bold proclamations in Latin, the ancient language of religion, law, and the secrets of life. In front of the amazed eyes of the assembled peasants the priest held high a piece of bread and exclaimed “Hoc est corpus!” — “This is the body!” — and the bread supposedly became the flesh of Christ. In the minds of the illiterate peasants, who did not speak Latin, “Hoc est corpus!” got garbled into “Hocus-pocus!” Thus was born the powerful spell that can transform a frog into a prince and a pumpkin into a carriage.6

Consumerism tells us that in order to be happy we must consume as many products and services as possible. If we feel that something is missing or not quite right, then we probably need to buy a product (a car, new clothes, organic food) or a service (housekeeping, relationship therapy, yoga classes). Every television commercial is another little legend about how consuming some product or service will make life better.

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.

Don’t believe tree-huggers who claim that our ancestors lived in harmony with nature. Long before the Industrial Revolution, Homo sapiens held the record among all organisms for driving the most plant and animal species to their extinctions. We have the dubious distinction of being the deadliest species in the annals of biology.

When humankind possesses enormous new powers, and when the threat of famine, plague and war is finally lifted, what will we do with ourselves? What will the scientists, investors, bankers and presidents do all day? Write poetry? Success

When you inflict suffering on yourself in the name of some story, it give you a choice: 'Either the story is true, or I am a gullible fool.' When you inflict suffering on others, you are also given a choice: 'Either the story is true, or I am a cruel villain.' And just as we don't want to admit we are fools, we also don't want to admit we are villains, so we prefer to believe that the story is true.

The currency of evolution is neither hunger nor pain, but rather copies of DNA helixes. Just as the economic success of a company is measured only by the number of dollars in its bank account, not by the happiness of its employees, so the evolutionary success of a species is measured by the number of copies of its DNA.

The Google and Facebook algorithms not only know exactly how you feel, they also know myriad other things about you that you hardly suspect. Consequently you should stop listening to your feelings and start listening to these external algorithms instead. What’s the point of having democratic elections when the algorithms know not only how each person is going to vote, but also the underlying neurological reasons why one person votes Democrat while another votes Republican? Whereas humanism commanded: ‘Listen to your feelings!’ Dataism now commands: ‘Listen to the algorithms! They know how you feel.’ When

Politics, too, is a second-order chaotic system. Many people criticise Sovietologists for failing to predict the 1989 revolutions and castigate Middle East experts for not anticipating the Arab Spring revolutions of 2011. This is unfair. Revolutions are, by definition, unpredictable. A predictable revolution never erupts.

The merger of infotech and biotech might soon push billions of humans out of the job market and undermine both liberty and equality. Big Data algorithms might create digital dictatorships in which all power is concentrated in the hands of a tiny elite while most people suffer not from exploitation but from something far worse — irrelevance.

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

There is some evidence that the size of the average Sapiens brain has actually decreased since the age of foraging.
