Quotes by Yuval Noah Harari

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.

Healing is the initial justification for every upgrade.

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.

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.

fantasy gives meaning to the suffering.

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.

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.

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.

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.

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.

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

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.

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

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.

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

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.
