What this covers
Yuval Harari, a historian from Hebrew University, speaks with Russ Roberts on EconTalk about the sources and consequences of human dominance. Harari's central claim is that humans conquered the world not through individual superiority but through an unusual talent: the ability to believe in and act upon shared fictions—money, religion, nations, human rights—that allow strangers to cooperate at scale. The conversation traces this capacity from the Cognitive Revolution roughly 70,000 years ago, when Homo sapiens began producing art and large-scale politics, through agriculture, empire, and science to the present day. A recurring tension runs throughout: the rise of collective human power has not made individual humans happier or healthier, at least not proportionally.
The discussion spans several distinct territories. Harari argues that money has no intrinsic worth—gold is too soft for tools, paper has no function—and exists only as expectation enforced by authority and violence. Adam Smith's insight that economies can be positive-sum rather than zero-sum is presented as revolutionary but fragile. The scientific revolution succeeded, in Harari's view, because it embraced ignorance: the admission that answers were unknown, which created motive to seek them. Empires receive ambiguous treatment—they were brutal and widespread, yet most human culture, language, and religion are products of imperial conquest. Most contentiously, Harari treats human rights and desires themselves as fictions: rights do not exist in biology, and even the urge to travel or the injunction to "follow your heart" are recent cultural inventions, not natural inclinations. The conversation concludes by noting that unlimited Luxury-to-Necessity Ratchet consumption would exhaust the planet.
Harari argues that humanity's dominance rests not on individual intelligence or tools but on the unique ability to cooperate flexibly in large numbers via shared fictions—money, religion, nations, human rights, capitalism—and that this same capacity drove agriculture, empire, and science while leaving individual human wellbeing largely uncorrelated with rising power.
- Large-scale human cooperation always rests on shared fictional stories that strangers can trust.
- Money is fundamentally made of trust/expectation, not intrinsic value of gold or paper.
- The agricultural revolution increased collective power while worsening the average individual's life.
Money, rights, and other institutions exist only as shared fictions generating trust among strangers.
- Human rights are a fictional story humans invented, not an objective biological reality; if you examine a human body you find organs, genes, and hormones but no rights—rights exist only in the stories we tell, just like money and corporations.
“If you take a human being and look inside, you find all kinds of organs and genes and hormones; but you don't find any rights”
- Trade is not purely pragmatic because it requires trusting a stranger who could cheat or kill you; a shared religion, ideology, or invented common ancestor creates the basis for trust, which is why no animal but Sapiens trades and why all documented Sapiens trade networks rested on fictions—and modern money operates the same way.
“the problem is you need to trust the other guy... if you have some kind of common religion or ideology with that stranger... then this can form the basis for a mutually beneficial relationship”
- European empires built trust in valueless paper money among colonized African populations by demanding that taxes be paid in that money and using violence against non-compliers, creating an initial need for the currency that established its acceptance.
“what they do is they demand that the local population pay taxes with money... if they don't pay their taxes... they use violence. So this creates the initial trust”
- Modern money has no intrinsic value—it can be gold, silver, paper, or electronic data—but functions because everyone trusts a shared authority like the Federal Reserve and the stories it tells; at the deepest level all money is made simply of trust, and over 90% of dollars exist only as electronic data.
“At the most basic level, I think all money is made of trust. It can be in physical terms money can be gold or silver or paper or even electronic data. But at a deeper level, all money is made simply of trust.”
- If you take all real dollar bills, paper, and coins, they amount to less than 10% of the dollars that exist on computers—most money today is just electronic data.
“If you take all of the real dollar bills and the paper and the nickels and all of that, it's less than 10% of the dollars that are on your computers.”
Humans uniquely cooperate in large numbers through shared fictional stories rather than genetic programming.
- Humankind controls the world primarily due to its ability to cooperate flexibly in large numbers, and the basis of all large-scale human cooperation is fiction, mythology, and storytelling—since no other animal can be convinced to act on a shared imagined story like heaven, only humans build cathedrals or go on Crusades.
“humankind controls the world, primarily due to our ability to cooperate flexibly in large numbers... if you dig deep enough, you always find fiction, mythology, story-telling at the basis of all large-scale human cooperation”
- Ants and bees cooperate but only rigidly, in a manner predetermined by their genetic code; they cannot reinvent their social systems overnight (e.g. execute the queen and establish a republic), whereas humans can change social systems within a year without any DNA change, simply by changing the stories they believe—as in the French and American Revolutions.
“among ants and bees, the cooperation is very rigid. It's predetermined by their genetic code”
- Sapiens' decisive advantage over Neanderthals and megafauna was not superior tools (both used fire, spears, and stone tools) but the ability to cooperate in large networks of hundreds or thousands, evidenced by long-distance trade and elaborate chieftain burials from 30-40,000 years ago, whereas Neanderthals lived in small bands of 30-50.
“The real advantage of Homo sapiens was in the ability to cooperate in large numbers. Whereas Neanderthals lived in small bands, maybe 30, 40, 50... Homo sapiens could create networks of cooperation encompassing hundreds, even thousands of individuals.”
- Until about 70,000 years ago humans were ecologically insignificant animals, but in East Africa Homo sapiens suddenly began cooperating in larger numbers and producing art, religion, and large-scale politics, then spread worldwide—reaching Australia ~50,000 years ago and the Americas ~15,000 years ago—within an evolutionarily short time.
“about 70,000 years ago in East Africa we suddenly see humans starting to do very strange things, revolutionary things. They start to cooperate in larger numbers. We see the first appearance of art, of religion, of large-scale politics.”
Empires were historically the dominant political system lasting centuries despite popular misconceptions of their failure.
- The claim that empires don't work is factually wrong: for at least 2000 years empire has been the most successful political system, most people lived in empires, and most empires collapsed not from subject revolts but from external invasion or internal elite conflict, with some lasting centuries.
“For the last, at least 2000 years, empire has been the most successful political system in the world. Most people for the last 2000 years lived in empires.”
- Most of contemporary culture is an imperial legacy—the languages most people think and dream in (English, French, Spanish, Arabic, Turkish, Russian, Chinese) and most major religions were created and spread, often violently, by empires—so to call empires simply evil implies most human culture is the product of evil.
“most people today on the planet talk and think and dream in imperial languages--languages which were created and spread, sometimes with violence, by empire”
- For most of the last 500 years science and empire were two sides of the same coin—European empires could not have conquered the world without modern science, and modern science was developed largely thanks to imperial investment—sharing a mindset of exploring and conquering, studying things not merely to know but to control them, as exemplified by Darwin sailing on a Royal Navy military mapping expedition rather than a scientific one.
“for most of the last 500 years, science and empire were two sides of the same coin. The European empires could not have spread and conquered the world without the help of modern science. And vice versa.”
Capitalism functions as a religion promising earthly paradise and reshaping human desire toward endless growth.
- Compared to most religions, which promise paradise only in an unverifiable afterlife, capitalism promises a paradise on earth and actually delivers many of its promises—helping overcome famine, plague, and even war—making it perhaps the most successful religion in history, believed in by Jews, Muslims, Christians, and Hindus alike, while also being responsible for terrible collective and individual harms like ecological destruction.
“Capitalism promises a sort of paradise here on earth. And again, compared to most other religions, it provides a lot of its promises.”
- Capitalism is best understood as a religion or ideology holding that economic growth is the most important thing in the world because it is the key to everything else—happiness, justice, freedom, democracy, rights—paired with the individual-level story that the solution to any problem is to buy and consume more, which feeds back into the need for more production and growth.
“I would define capitalism as the religion or ideology which thinks that economic growth is the most important thing in the world, because it's the key to everything else”
- Where societies historically assumed individuals must be disciplined to settle for what they have in order to maintain social harmony, capitalism's ethical revolution reversed this by encouraging people to want more and more—holding that greed and wealth are good and that egoism is altruism—because the greatest threat to the system is people settling for what they have, which would stop the growth the system requires.
“The revolutionary idea of capitalism is that... we have to encourage people to want more and more all the time, because this is the driving force behind economic growth”
Modern desires and individual aspirations are shaped by dominant cultural myths rather than natural human instincts.
- Many things people consider necessities were recently luxuries one could live without, and desires like the urge to travel are not natural but implanted by repeated cultural messaging—the recommendation to 'follow your heart' was itself installed by 19th-century Romantic and 20th-century consumerist myths, so the heart usually takes instructions from the dominant myths of the day.
“the very recommendation to "Follow your heart" was implanted in our minds by a combination of nineteenth-century Romantic myths and twentieth-century consumerist myths”
- Present-day Westerners' most cherished desires are shaped by Romantic, nationalist, capitalist, and humanist myths centuries old, so that even the advice to 'follow your heart' is misleading—the heart is a double agent that usually takes its instructions from the dominant myths of the day.
“the heart is a double agent that usually takes its instructions from the dominant myths of the day”
Agriculture and prosperity paradoxically enabled exploitation, population dependency, and reduced average individual wellbeing despite collective advances.
- Throughout history luxuries tend to become necessities as people become convinced they cannot live without them, which is especially problematic because if everyone in China, India, and Africa attained the average American standard of living—big houses, SUVs, vacations abroad—global ecology would collapse under present technology, forcing a stark choice between billions remaining unhappy and destroying the planet.
“luxuries tend to become necessities with the passing of time; and people become convinced that they cannot live without them”
- Humans have an amazing capacity to acquire power but are poor at translating it into happiness and wellbeing; using objective measures like life expectancy and child mortality there was essentially no correlation between power and wellbeing until roughly the early 19th century, and even the modest correlation of the last 200 years is accompanied by problematic developments that prevent declaring the problem solved.
“humans have an amazing capacity to acquire power. But they are not good at all at translating power into happiness and into wellbeing”
- Agriculture was a huge step forward for the collective (enabling cities and empires) but a trap for the average individual: peasants worked harder at bodily and mentally tougher tasks, ate a more monotonous and nutrient-poor diet, suffered more infectious diseases from domesticated animals and unhygienic villages, and lived under steep new social hierarchies of exploitation—making the average peasant's life worse than that of earlier hunter-gatherers.
“for the collective and for the elites, agriculture was a very good thing. But for the average peasant in ancient Egypt or medieval Europe, agriculture was a much less positive development”
- People did not abandon farming despite its hardships because agriculture supported far larger populations who would starve if they reverted, because coercive elites who now controlled society would not permit it, and because the skills needed to live as hunter-gatherers had been lost—so a peasant attempting to return to the forest would quickly die.
“Agriculture supported demographic growth. You had many more people... you simply couldn't go back without most of the population dying from hunger”
Historical study widens horizons and reveals contingency rather than predicting futures or extracting practical lessons.
- For most of history people experienced the world as zero-sum, believing one person or kingdom could grow richer only by making another poorer, but Adam Smith and others introduced the revolutionary—simultaneously economic, ethical, and religious—idea that the whole pie can grow so everyone can profit at once; this insight has so far proven correct for humans even if not for other animals, yet remains very hard to grasp.
“Most of existence is zero-sum games in which your profits are my loss... But then came along Adam Smith... they had the notion that everybody can profit at the same time because the entire... pie can grow simultaneously”
- The common idea that we study history to repeat past good decisions and avoid bad ones never works, because the present and future are so different from anything that happened before that no useful generalizations or practical decisions can be reliably drawn from past patterns.
“Some people think that we'll study the good decisions and bad decisions from the past, and simply repeat the good decisions and avoid the bad decisions. But it never works like that.”
- Unlike physics, history is not a means for accurate prediction; we study history not to know the future but to widen our horizons, because historical processes shaped not only our societies but our very thoughts, fears, and hopes—and understanding this gives us a degree of freedom to envision alternative futures we would otherwise be unable to imagine.
“very often, our deepest desires and fears and expectations are shaped by history. And we don't know it. And this limits our ability to envision alternatives”
Science's breakthrough was recognizing ignorance, enabling solutions to previously intractable problems like disease and famine.
- Science overcame the most lethal infectious diseases and famine, which were long thought to be unalterable parts of the natural order solvable only by divine intervention, so that today more people die from old-age diseases than from infectious diseases and more die from eating too much than from eating too little.
“today, more people, for the first time in history, die from old age diseases than from infectious diseases... today, more people die from eating too much than from eating too little”
- Pre-modern cultures believed they already had all important answers in scripture, removing the incentive to seek new knowledge; the scientific revolution's most important discovery was ignorance—admitting that many important questions had no known answer—which created the incentive to seek new knowledge and enabled humans to solve problems like plagues and famine previously thought to be insoluble parts of the natural order.
“the most important discovery of the scientific revolution was the discovery of ignorance--of the fact that there are many important questions which we don't know the answer to”
Homo sapiens rapidly expanded globally and displaced all other human species through large-scale cooperation.
- Beginning about 50,000 years ago there is a correlation between the arrival of Homo sapiens in a new region and the mass extinction of large animals—over 90% of Australia's big animals disappeared shortly after arrival ~50,000 years ago, and about 70% of America's large creatures vanished within 2-3,000 years of human arrival ~15,000 years ago, though this could be correlation rather than causation.
“more than 90% of all the big animals of Australia disappear. In America, it's about 70% of all the large creatures of America disappear within about 2 or 3000 years from the arrival of humans”
- Until roughly 60,000 years ago the world hosted many human species (like the Neanderthals in Europe), but as Homo sapiens spread from East Africa all other human species disappeared within a short time—probably the most thorough ethnic cleansing in history, accomplished with more or less violence.
“when Homo sapiens spreads from East Africa, all the other human species disappear within a very short time. It was probably the most thorough and most important ethnic cleansing... in history”
Artificial intelligence and technological change will make current career and education planning unreliable.
- The world of 2050 will be radically different and unpredictable; many experts estimate artificial intelligence will take roughly 50% of US jobs within 30 to 40 years, such that we may not need most human doctors or lawyers because computers will do those jobs better, leaving no clear answer to what a young person should study for a useful future profession.
“many experts estimate that artifical intelligence will take maybe 50% of the jobs in the USA within 30 or 40 years”
