21 Lessons for the 21st Century Hardcover – September 4, 2018
Purchase options and add-ons
“Fascinating . . . a crucial global conversation about how to take on the problems of the twenty-first century.”—Bill Gates, The New York Times Book Review
A FINANCIAL TIMES BEST BOOK OF THE YEAR
How can we protect ourselves from nuclear war or ecological catastrophe? What do we do about the epidemic of fake news or the threat of terrorism? How should we prepare our children for the future?
21 Lessons for the 21st Century is a probing and visionary investigation into today’s most urgent issues as we move into the future. As technology advances faster than our understanding of it, hacking becomes a tactic of war, and the world feels more polarized than ever, Harari addresses the challenge of navigating life in the face of constant and disorienting change and raises the important questions we need to ask ourselves in order to survive.
In twenty-one accessible chapters that are both provocative and profound, Harari untangles political, technological, social, and existential issues and offers advice on how to prepare for a very different future from the world we now live in: How can we retain freedom of choice when Big Data is watching us? What will the future workforce look like, and how should we ready ourselves for it? Why is liberal democracy in crisis?
Harari’s unique ability to make sense of where we have come from and where we are going has captured the imaginations of millions of readers. Here he invites us to consider values, meaning, and personal engagement in a world full of noise and uncertainty. When we are deluged with irrelevant information, clarity is power. Presenting complex contemporary challenges clearly and accessibly, 21 Lessons for the 21st Century is essential reading.

Review
“If there were such a thing as a required instruction manual for politicians and thought leaders, Israeli historian Yuval Noah Harari’s 21 Lessons for the 21st Century would deserve serious consideration. In this collection of provocative essays, Harari, author of the critically praised Sapiens and Homo Deus, tackles a daunting array of issues, endeavoring to answer a persistent question: ‘What is happening in the world today, and what is the deep meaning of these events?’ . . . Harari makes a passionate argument for reshaping our educational systems and replacing our current emphasis on quickly outdated substantive knowledge with the ‘four Cs’—critical thinking, communication, collaboration and creativity. . . . Thoughtful readers will find 21 Lessons for the 21st Century to be a mind-expanding experience.”—BookPage (top pick)
“A sobering and tough-minded perspective on bewildering new vistas.”—Booklist (starred review)
“Magnificently combining historical, scientific, political, and philosophical perspectives, Harari . . . explores twenty-one of what he considers to be today’s ‘greatest challenges.’ Despite the title’s reference to ‘lessons,’ his tone is not prescriptive but exploratory, seeking to provoke debate without offering definitive solutions. . . . Within this broad construct, Harari discusses many pressing issues, including problems associated with liberal democracy, nationalism, immigration, and religion. This well-informed and searching book is one to be savored and widely discussed.”—Publishers Weekly (starred review)
“A highly instructive exploration of ‘current affairs and . . . the immediate future of human societies.’ Having produced an international bestseller about human origins and avoided the sophomore jinx writing about our destiny, Harari proves that he has not lost his touch, casting a brilliantly insightful eye on today’s myriad crises, from Trump to terrorism, Brexit to big data. . . . [In] twenty-one painfully astute essays, he delivers his take on where our increasingly ‘post-truth’ world is headed. Human ingenuity, which enables us to control the outside world, may soon re-engineer our insides, extend life, and guide our thoughts. Science-fiction movies get the future wrong, if only because they have happy endings. Most readers will find Harari’s narrative deliciously reasonable, including his explanation of the stories (not actually true but rational) of those who elect dictators, populists, and nationalists. His remedies for wildly disruptive technology (biotech, infotech) and its consequences (climate change, mass unemployment) ring true, provided nations act with more good sense than they have shown throughout history. Harari delivers yet another tour de force.”—Kirkus Reviews (starred review)
About the Author

Disillusionment
The End of History Has Been Postponed
Humans think in stories rather than in facts, numbers, or equations, and the simpler the story, the better. Every person, group, and nation has its own tales and myths. But during the twentieth century the global elites in New York, London, Berlin, and Moscow formulated three grand stories that claimed to explain the whole past and to predict the future of the entire world: the fascist story, the communist story, and the liberal story. The Second World War knocked out the fascist story, and from the late 1940s to the late 1980s the world became a battleground between just two stories: communism and liberalism. Then the communist story collapsed, and the liberal story remained the dominant guide to the human past and the indispensable manual for the future of the world—or so it seemed to the global elite.
The liberal story celebrates the value and power of liberty. It says that for thousands of years humankind lived under oppressive regimes that allowed people few political rights, economic opportunities, or personal liberties, and which heavily restricted the movements of individuals, ideas, and goods. But people fought for their freedom, and step by step, liberty gained ground. Democratic regimes took the place of brutal dictatorships. Free enterprise overcame economic restrictions. People learned to think for themselves and follow their hearts instead of blindly obeying bigoted priests and hidebound traditions. Open roads, wide bridges, and bustling airports replaced walls, moats, and barbed-wire fences.
The liberal story acknowledges that not all is well in the world and that there are still many hurdles to overcome. Much of our planet is dominated by tyrants, and even in the most liberal countries many citizens suffer from poverty, violence, and oppression. But at least we know what we need to do in order to overcome these problems: give people more liberty. We need to protect human rights, grant everybody the vote, establish free markets, and let individuals, ideas, and goods move throughout the world as easily as possible. According to this liberal panacea—accepted, in slight variations, by George W. Bush and Barack Obama alike—if we just continue to liberalize and globalize our political and economic systems, we will produce peace and prosperity for all.1
Countries that join this unstoppable march of progress will be rewarded with peace and prosperity sooner. Countries that try to resist the inevitable will suffer the consequences until they too see the light, open their borders, and liberalize their societies, their politics, and their markets. It may take time, but eventually even North Korea, Iraq, and El Salvador will look like Denmark or Iowa.
In the 1990s and 2000s this story became a global mantra. Many governments from Brazil to India adopted liberal recipes in an attempt to join the inexorable march of history. Those failing to do so seemed like fossils from a bygone era. In 1997 U.S. president Bill Clinton confidently rebuked the Chinese government, stating that its refusal to liberalize Chinese politics put it “on the wrong side of history.”2
However, since the global financial crisis of 2008 people all over the world have become increasingly disillusioned with the liberal story. Walls and firewalls are back in vogue. Resistance to immigration and to trade agreements is mounting. Ostensibly democratic governments undermine the independence of the judiciary system, restrict the freedom of the press, and portray any opposition as treason. Strongmen in countries such as Turkey and Russia experiment with new types of illiberal democracies and outright dictatorships. Today, few would confidently declare that the Chinese Communist Party is on the wrong side of history.
The year 2016—marked by the Brexit vote in Britain and the rise of Donald Trump in the United States—signified the moment when this tidal wave of disillusionment reached the core liberal states of Western Europe and North America. Whereas a few years ago Americans and Europeans were still trying to liberalize Iraq and Libya at gunpoint, many people in Kentucky and Yorkshire now have come to see the liberal vision as either undesirable or unattainable. Some discovered a liking for the old hierarchical world, and they just don’t want to give up their racial, national, or gendered privileges. Others have concluded (rightly or wrongly) that liberalization and globalization are a huge racket empowering a tiny elite at the expense of the masses.
In 1938 humans were offered three global stories to choose from, in 1968 just two, and in 1998 a single story seemed to prevail. In 2018 we are down to zero. No wonder that the liberal elites, who dominated much of the world in recent decades, are in a state of shock and disorientation. To have one story is the most reassuring situation of all. Everything is perfectly clear. To be suddenly left without any story is terrifying. Nothing makes any sense. A bit like the Soviet elite in the 1980s, liberals don’t understand how history deviated from its preordained course, and they lack an alternative prism through which to interpret reality. Disorientation causes them to think in apocalyptic terms, as if the failure of history to come to its envisioned happy ending can only mean that it is hurtling toward Armageddon. Unable to conduct a reality check, the mind latches onto catastrophic scenarios. Like a person imagining that a bad headache signifies a terminal brain tumor, many liberals fear that Brexit and the rise of Donald Trump portend the end of human civilization.
From Killing Mosquitoes to Killing Thoughts
Our sense of disorientation and impending doom is exacerbated by the accelerating pace of technological disruption. The liberal political system was shaped during the industrial era to manage a world of steam engines, oil refineries, and television sets. It has difficulty dealing with the ongoing revolutions in information technology and biotechnology.
Both politicians and voters are barely able to comprehend the new technologies, let alone regulate their explosive potential. Since the 1990s the internet has changed the world probably more than any other factor, yet the internet revolution was directed by engineers more than by political parties. Did you ever vote about the internet? The democratic system is still struggling to understand what hit it, and it is unequipped to deal with the next shocks, such as the rise of AI and the blockchain revolution.
Already today, computers have made the financial system so complicated that few humans can understand it. As AI improves, we might soon reach a point when no human can make sense of finance anymore. What will that do to the political process? Can you imagine a government that waits humbly for an algorithm to approve its budget or its new tax reform? Meanwhile, peer-to-peer blockchain networks and cryptocurrencies such as Bitcoin might completely revamp the monetary system, making radical tax reforms inevitable. For example, it might become impossible or irrelevant to calculate and tax incomes in dollars, because most transactions will not involve a clear-cut exchange of national currency, or any currency at all. Governments might therefore need to invent entirely new taxes—perhaps a tax on information (which will be both the most important asset in the economy and the only thing exchanged in numerous transactions). Will the political system manage to deal with the crisis before it runs out of money?
Even more important, the twin revolutions in infotech and biotech could restructure not just economies and societies but our very bodies and minds. In the past, we humans learned to control the world outside us, but we had very little control over the world inside us. We knew how to build a dam and stop a river from flowing, but we did not know how to stop the body from aging. We knew how to design an irrigation system, but we had no idea how to design a brain. If a mosquito buzzed in our ear and disturbed our sleep, we knew how to kill the mosquito, but if a thought buzzed in our mind and kept us awake at night, most of us did not know how to kill the thought.
The revolutions in biotech and infotech will give us control of the world inside us and will enable us to engineer and manufacture life. We will learn how to design brains, extend lives, and kill thoughts at our discretion. Nobody knows what the consequences will be. Humans were always far better at inventing tools than using them wisely. It is easier to manipulate a river by building a dam than it is to predict all the complex consequences this will have for the wider ecological system. Similarly, it will be easier to redirect the flow of our minds than to divine what that will do to our personal psychology or to our social systems.
In the past, we gained the power to manipulate the world around us and reshape the entire planet, but because we didn’t understand the complexity of the global ecology, the changes we made inadvertently disrupted the entire ecological system, and now we face an ecological collapse. In the coming century biotech and infotech will give us the power to manipulate the world inside us and reshape ourselves, but because we don’t understand the complexity of our own minds, the changes we will make might upset our mental system to such an extent that it too might break down.
The revolutions in biotech and infotech are currently being started by engineers, entrepreneurs, and scientists who are hardly aware of the political implications of their decisions, and who certainly don’t represent anyone. Can parliaments and political parties take matters into their own hands? At present it does not seem so. Technological disruption is not even a leading item on the political agenda. During the 2016 U.S. presidential race, the main reference to disruptive technology concerned Hillary Clinton’s email debacle, and despite all the talk about job loss, neither candidate addressed the potential impact of automation.3 Donald Trump warned voters that the Mexicans and Chinese would take their jobs, and that they should therefore build a wall on the Mexican border.4 He never warned voters that algorithms would take their jobs, nor did he suggest building a firewall on the border with California.
This might be one of the reasons (though not the only one) voters even in the heartlands of the liberal West are losing faith in the liberal story and in the democratic process. Ordinary people may not understand artificial intelligence and biotechnology, but they can sense that the future is passing them by. In 1938 the condition of the common person in the USSR, Germany, or the United States may have been grim, but he was constantly told that he was the most important thing in the world, and that he was the future (provided, of course, that he was an “ordinary person” rather than a Jew or an African). He looked at the propaganda posters—which typically depicted coal miners, steelworkers, and housewives in heroic poses—and saw himself there: “I am in that poster! I am the hero of the future!”5
In 2018 the common person feels increasingly irrelevant. Lots of mysterious words are bandied around excitedly in TED Talks, government think tanks, and high-tech conferences—globalization, blockchain, genetic engineering, artificial intelligence, machine learning—and common people may well suspect that none of these words are about them. The liberal story was the story of ordinary people. How can it remain relevant to a world of cyborgs and networked algorithms?
In the twentieth century, the masses revolted against exploitation and sought to translate their vital role in the economy into political power. Now the masses fear irrelevance, and they are frantic to use their remaining political power before it is too late. Brexit and the rise of Trump might therefore demonstrate a trajectory opposite to that of traditional socialist revolutions. The Russian, Chinese, and Cuban revolutions were made by people who were vital to the economy but who lacked political power; in 2016, Trump and Brexit were supported by many people who still enjoyed political power but who feared that they were losing their economic worth. Perhaps in the twenty-first century populist revolts will be staged not against an economic elite that exploits people but against an economic elite that does not need them anymore.6 This may well be a losing battle. It is much harder to struggle against irrelevance than against exploitation.

- Reviewed in the United States on January 12, 2024Format: HardcoverVerified PurchaseI did a cover-to-cover preview, having received my copy of it late yesterday afternoon. I actually spent about two hours, reading short excerpts and getting a feel for how the writer marshals his facts and crafts his arguments. From there, I previewed the enumerated topics of the book, following the flow of argument and the evidence Yuval Noah Harari refers to make his point. The main thing about this book is to understand that the 21st century is going to be unlike anything humankind has experienced in the past. Our prior experience will not necessarily be a trustworthy guide to our future as a species. Harare is an Israeli Jew who came to knowledge of the world rather late. Growing up he mentions that his education Israel was utterly devoid of knowledge of European and world history, nor was he aware of the historical developments that characterized the Middle Ages, the Age of Exploration and European conquest of the non-European world. He knew of European history only in so far as it gave him an understanding about how he and his forebears ended up in the Land of Israel. Coming onto the subject cold, this new cornucopia of knowledge offered him certain advantages insofar as you learn to take nothing for granted or at face value. For people who emigrate to a new land, with different attitudes and customs from those they have known, there is the painful process that all immigrants experience in figuring out who they are, and how quickly they need to learn how to survive in this new environment. Harari is perhaps among the most incisive and farseeing writers I have encountered in recent times. He holds a PhD from Oxford University (no mean feat), and for someone who apparently spent his early years speaking and writing a non-Western language (Hebrew), his ability to translate his thoughts into English, and writing as well as he does, is an accomplishment that is beyond the reach of most other recent immigrants I have encountered in my lifetime. He must've spent an enormous amount of time with the Oxford Dictionary of the English Language!
It is clear to me that Harari is onto something. The strangeness that people feel when they run up against stuff they don't know, and have difficulty figuring out what to do, is going to be far beyond the cultural and linguistic barriers that recent immigrants typically experience. With English, there are thousands of words that have more than one meaning, and thousands of words that have shared meanings, depending upon context, and intent.
Harari is telling his readers to experience the strangeness that he must've felt speaking, writing, and using the English language for the first time. Most Americans are not used to learning foreign languages, because people come to America where relatively few people other than recent immigrants routinely converse and whatever other languages they happen to be trained in, or learn from infancy.
Briefly, the outline of this book is as follows.
In Part 1, Harari begins with a discussion of what he terms, "The Technological Challenge"., Followed by the head note reading, "Humankind is losing faith in the liberal story that dominated global politics in recent decades, exactly when the merger of Biotech and Infotech confronts us with the biggest challenges humankind has ever encountered."
He starts with, "Disillusionment; The End of History Has Been Postponed". Basically, Harari argues that humankind, having conquered the world, is vulnerable to technology that turns out to be an insidious threat to what it means to be human. He states that liberalism, as it used to be practiced at large in the world has reached something worse than just simply being a dead end, its consequences are becoming perverse. But conservatives should take no comfort from liberalism's embarrassment; nobody really wants to live in an authoritarian or fascistic state.
In today's world, 'work' is purposeful activity that society finds to be commercially useful, and worthy of paying money to people to perform whatever it is they do to make work productive. Harari says that work as we know it may become scarce because the skills that people acquire over a lifetime to make themselves productive enough to earn a living out of those activities, may be taken over by Artificial Intelligence, in which jobs that are not only repetitive, but includes those that require some form of judgment and discretion may become subsumed in the kind of tasks that AI can do more cost-effectively than people can. Undoubtedly, there will be numerous fixes that will be attempted to preserve jobs, but their prospects are likely to be some form of a rearguard action to delay the introduction of AI into those workspaces. Those worst off will likely be unskilled laborers were currently employed in Third World countries overseas at minimum wages. They will find that their labor is superfluous when a high tech companies in Silicon Valley, California, and elsewhere figure out how to harness 3D printers and comparable technologies to accomplish end-to-end production lines from concept to finished product for just about anything that is manufactured overseas.
So how do ordinary people earn money to meet their needs? How are they to be supported if they are not working in the private sector, for wages or salaries, and how much money will they need to survive. We are looking at Nth-degree consequences of a world in which machines and computer bots can manufacture whatever is needed to sustain human life. Programs of education and training need to be right-sized to meet the needs of the society as it exists nominally at the time of its inception, but for a generation or two down the road as school children mature into maturity, and thereafter into old age.
Political liberty and freedom are also on the auction block. What we experience today is freedom of choice, and how choices are arrived at, comes relatively recently in human history. Decision-making follows a well-trodden path where alternatives are weighed and measured, until the final choices made; what happens when humans are influenced by outside forces that they cannot fathom some of the choices they make benefit someone else, rather than themselves? What is to be said about 'free will' in the face of an AI algorithm that simulates human thinking and emotion? What can we say about 'Equality', when all meaningful data are owned by other people or corporate entities?
I'll leave the review here at this point, because having laid out some of the basic questions that Yuval Noah Harari writes about, I'll invite readers to find out for themselves by reading this highly provocative book.
- Reviewed in the United States on May 19, 2025Format: KindleVerified PurchaseI first heard of Harari on the Kara Swisher podcast. Listening to him discuss the issues around nascent technology I decided I wanted to know more. I started with this book and I was not disappointed. A very interesting take on the various directions humanity might be headed. If you are tired of listening to stupid, poorly structured arguments about our moment in history, this book is for you. The ideas and arguments are very tight, carefully researched and thoughtfully presented.
- Reviewed in the United States on February 28, 2019Format: HardcoverVerified PurchaseOur dentist recommended Harari’s “Sapiens” to my wife, which she read and so taken continued through his second book “Homo Deus,” and went on to his “21 Lessons” which she commended to me. While I usually have my own reading agenda, I eventually got around to completing the book and glad I did as it clearly and succinctly outlines the major challenges of our times.
While I do not agree with all of Harari’s characterizations or proposed solutions, I have to appreciate the directness and honesty in his delivery. Since his books are so popular and numerously reviewed, I only briefly refer to the content of Harari’s book and concentrate more on aspects that I found more or less useful.
Within the book, Harari’s progresses through 5 parts to present his “21 Lessons.” In Part I, he conveys “The Technological Challenge” resulting from developments such as in life and computer sciences including (1) Disillusionment, (2) Work, (3) Equality, and (4) Liberty. Continuing in Part II, the author discusses “The Political Challenge” that ensues from these occurrences consisting of (5) Community, (6) Civilization, (7) Nationalism, (8) Religion, and (9) Immigration. Within Part III, Harari deals with the “Despair and Hope” resulting in society involving (10) Terrorism, (11) War, (12) Humility, (13) God, and (14) Secularism. For Part IV, the author wrestles with the difficulties in getting at the “Truth” entailed in (15) Ignorance, (16) Justice, (17) Post Truth, and (18) Science Fiction. Finally, in Part V, he takes up “Resilience” and ways to continue to function and advance with (19) Education, (20) Meaning, and (21) Meditation.
Overall, I am impressed with Harari’s sweep as well as his ability as a historian to be a “disruptive thinker” and put important emerging issues into clear relief. His descriptions compare favorably with books such as Rutherford’s A Brief History of Everyone Who Ever Lived: The Stories in Our Genes, Barrett’s How Emotions Are Made and Lanier’s Who Owns the Future? in expressing the complexity in these topics and their extensive ramifications. The author’s discussions also remind me of those contained in Brooke Gladstone’s The Trouble with Reality: A Rumination on Moral Panic in Our Time.
On the other hand, Harari’s skepticism and pessimism in questioning prevailing views can seem a little too fatalistic; his views, at times, do not seem to offer someone like me with enough alternatives and options with which to advance or at least take next steps in coping beyond meditation----although perhaps that’s the place from which they come. A contrasting foil might be the optimism in Pinker’s Enlightenment Now: The Case for Reason, Science, Humanism, and Progress where he puts more stock in reason, science and humanism (see my review of this book and others mentioned).
Despite my criticism, Harari is very much worth reading for the way he portrays current human problems and those coming over the horizon that require our attention now and into the future.

5.0 out of 5 stars Audaciosamente ousado. Vale a pena cada página.
Audaciosamente ousado em pensar o presente e o futuro próximos. Embora tenha sido público há cinco anos (2018), continua atualíssimo, especialmente em face da popularização do Chat-GPT. Comprei a edição de bolso em inglês para evitar os reincidentes problemas com traduções nacionais. Foi inclusive mais barato!

4.0 out of 5 stars It's a curious read
For me, this is the second book that I read from the current trilogy and it is, as the author concedes, a distinctly different book from the first and thus presumably too from the third. With far more speculation, I found more freedom as a reader to disagree with the concepts and presented interpretations here than before, of course. Although a different experience, it was nice to feel like I was involved, in some sense, in the actual text, in the conversation. But a word of warning, it pulls no punches during the first few chapters on the merging of bio and info tech - and left me feeling a mix of curiosity, intrigue, concern, and perhaps a little worry.

5.0 out of 5 stars Un Harari aussi passionnant que Sapiens
Je ne l'ai pas encore terminé (ça ne se lit pas aussi vite qu'un roman et ça fatigue un peu la tête). Harari a toujours une façon originale d'aborder les problèmes et de prendre du recul avant de les analyser. Très documenté. Pas forcément optimiste et un peu à contre-courant du politiquement correct, surtout sur les problèmes de migration et d'intégration, mais toujours rationnel et factuel.
