21 Lessons for the 21st Century

Yuval Noah Harari

**THE NUMBER ONE BESTSELLER** The future is here. Learn to live in it. In twenty-one bite-sized lessons, Yuval Noah Harari explores what it means to be human in an age of bewilderment. How can we protect ourselves from nuclear war, ecological cataclysms and technological disruptions? What can we do about the epidemic of fake news or the threat of terrorism? What should we teach our children? Yuval Noah Harari takes us on a thrilling journey through today’s most urgent issues. The golden thread running through his exhilarating new book is the challenge of maintaining our collective and individual focus in the face of constant and disorienting change. Are we still capable of understanding the world we have created? ‘Fascinating... compelling... [Harari] has teed up a crucial global conversation about how to take on the problems of the 21st century’ Bill Gates, New York Times ‘Truly mind-expanding... Ultra-topical’ Guardian ‘21 Lessons is, simply put, a crucial book’ Adam Kay

“In such a world, the last thing a teacher needs to give her pupils is more information. They already have far too much of it. Instead, people need the ability to make sense of information, to tell the difference between what is important and what is unimportant, and above all to combine many bits of information into a broad picture of the world.”

“In less than a hundred years the Germans organised themselves into six very different systems: the Hohenzollern Empire, the Weimar Republic, the Third Reich, the German Democratic Republic (aka communist East Germany), the Federal Republic of Germany (aka West Germany), and finally democratic reunited Germany. Of course the Germans kept their language and their love of beer and bratwurst. But is there some unique German essence that distinguishes them from all other nations, and that has remained unchanged from Wilhelm II to Angela Merkel?”

“Without criticising the liberal model, we cannot repair its faults or go beyond it. But please note that this book could have been written only when people are still relatively free to think what they like and to express themselves as they wish. If you value this book, you should also value the freedom of expression.”

“If we are willing to make such efforts in order to understand foreign cultures, unknown species and distant planets, it might be worth working just as hard in order to understand our own minds. And we had better understand our minds before the algorithms make our minds up for us.”

“The typical scientist doesn’t actually practise meditation herself. Rather, she invites experienced meditators to her laboratory, covers their heads with electrodes, asks them to meditate, and observes the resulting brain activities. That can teach us many interesting things about the brain, but if the aim is to understand the mind, we are missing some of the most important insights.”

“For years I lived under the impression that I was the master of my life, and the CEO of my own personal brand. But a few hours of meditation were enough to show me that I hardly had any control of myself. I was not the CEO – I was barely the gatekeeper. I was asked to stand at the gateway of my body – the nostrils – and just observe whatever comes in or goes out. Yet after a few moments I lost my focus and abandoned my post.”

“In the early twenty-first century, perhaps the most important artistic genre is science fiction. Very few people read the latest articles in the fields of machine learning or genetic engineering. Instead, movies such as The Matrix and Her and TV series such as Westworld and Black Mirror shape how people understand the most important technological, social and economic developments of our time.”

“Drinking lots of Coca-Cola will not make you young, will not make you healthy, and will not make you athletic – rather, it increases your chances of suffering from obesity and diabetes. Yet for decades Coca-Cola has invested billions of dollars in linking itself to youth, health and sports – and billions of humans subconsciously believe in this linkage.”

“Leaders are thus trapped in a double bind. If they stay in the centre of power, they will have an extremely distorted vision of the world. If they venture to the margins, they will waste too much of their precious time. And the problem will only get worse. In the coming decades, the world will become even more complex than it is today. Individual humans – whether pawns or kings – will consequently know even less about the technological gadgets, the economic currents, and the political dynamics that shape the world. As Socrates observed more than 2,000 years ago, the best we can do under such conditions is to acknowledge our own individual ignorance.”

“One would have thought that conservatives would care far more about the conservation of the old ecological order, and about protecting their ancestral lands, forests and rivers. In contrast, progressives could be expected to be far more open to radical changes to the countryside, especially if the aim is to speed up progress and increase the human standard of living. However, once the party line has been set on these issues by various historical quirks, it has become second nature for conservatives to dismiss concerns about polluted rivers and disappearing birds, while left-wing progressives tend to fear any disruption to the old ecological order.”

“The most important secular commitment is to the truth, which is based on observation and evidence rather than on mere faith. Seculars strive not to confuse truth with belief.”

“Not visiting any temples and not believing in any god is also a viable option. As the last few centuries have proved, we don’t need to invoke God’s name in order to live a moral life. Secularism can provide us with all the values we need.”

“When I think of the mystery of existence, I prefer to use other words, so as to avoid confusion. And unlike the God of the Islamic State and the Crusades – who cares a lot about names and above all about His most holy name – the mystery of existence doesn’t care an iota what names we apes give it.”

“Diabetes and high sugar levels kill up to 3.5 million people annually, while air pollution kills about 7 million people.3 So why do we fear terrorism more than sugar, and why do governments lose elections because of sporadic terror attacks but not because of chronic air pollution?”

“If Greeks and Germans cannot agree on a common destiny, and if 500 million affluent Europeans cannot absorb a few million impoverished refugees, what chances do humans have of overcoming the far deeper conflicts that beset our global civilisation?”

“I cannot name the 8 million people who share my Israeli citizenship, I have never met most of them, and I am very unlikely ever to meet them in the future. My ability to nevertheless feel loyal to this nebulous mass is not a legacy from my hunter-gatherer ancestors, but a miracle of recent history.”

“But in reality, there is no reason to assume that artificial intelligence will gain consciousness, because intelligence and consciousness are very different things. Intelligence is the ability to solve problems. Consciousness is the ability to feel things such as pain, joy, love and anger. We tend to confuse the two because in humans and other mammals intelligence goes hand in hand with consciousness. Mammals solve most problems by feeling things. Computers, however, solve problems in a very different way.”

“The loss of many traditional jobs in everything from art to healthcare will partly be offset by the creation of new human jobs. GPs who focus on diagnosing known diseases and administering familiar treatments will probably be replaced by AI doctors. But precisely because of that, there will be much more money to pay human doctors and lab assistants to do groundbreaking research and develop new medicines or surgical procedures.”

“But liberalism has no obvious answers to the biggest problems we face: ecological collapse and technological disruption. Liberalism traditionally relied on economic growth to magically solve difficult social and political conflicts.”
