Director Daniel Bell Interviews Yuval Harari on His New Book, Sapiens: A Brief History of Mankind

On May 11, 2016, the Berggruen Philosophy and Culture Center (BPPC) invited Yuval Noah Harari, a professor of history at Hebrew University in Jerusalem and author of the international bestseller Sapiens: A Brief History of Humankind, to deliver a talk on “The New Inequalities” at Tsinghua University in Beijing. Prior to the talk, Harari was interviewed at Tsinghua’s Institute for Advanced Study in the Humanities and the Social Sciences by Tsinghua professor and BPPC director Daniel A. Bell. This is an edited transcript of the interview. The interview can be viewed here: http://tinyurl.com/z6dyctk

A Gamble That Paid Off

DANIEL:  It’s a great pleasure to meet you and I loved your book.

YUVAL:  Thank you.

DANIEL: I want to ask you what motivated you to write the book because you’re an academic and as you know our academic colleagues typically reward highly specialized work written in language that’s not very accessible.  But your book is very erudite, interdisciplinary, colloquial, humorous, and has lots of pictures so it really goes against the grain of what academics are supposed to do. What gave you the courage, or maybe we should say the chutzpah, to write this book? It was a gamble that paid off but still, it was a gamble and what made you decide to take this gamble?

YUVAL:  Well, I think that what gave me the courage to do it is that I got my tenure. I became secure in my academic post at the Hebrew University of Jerusalem, and I didn’t have to worry anymore about “publish or perish”.  I could do what I really wanted to do which was to look at the broad questions of history and to try and communicate important academic and scientific insights to the general public.  I don’t know how it is in China or in other countries, but certainly in Israel most people learn and know only local history and national history. They learn Israeli and Jewish history. But we now live in a global world, and there are no longer really independent countries.  All the major problems of the world are global in nature;  whether it’s global warming or the rise of artificial intelligence. I therefore thought that the general public needs a good grasp of global history in order to understand their own lives. 

DANIEL:  But what made you know that you would write a great book that is accessible to the public because many academics have that aspiration but not many can pull it off.

YUVAL:  Well it was really written in dialogue with my students at the university.  It came out of a course that I was teaching for seven or eight years. I could experiment with the students and see what they find boring and what they find interesting.  And in this way I learned how to communicate with the general public.  

DANIEL: You practiced on your students and you discover what they find interesting so therefore many other people, including the rest of the world would also find it interesting.  

YUVAL:  Yes, and also, very often when you just write a book you have some idea in your head and you write it down and you think it’s clear. You think you understand what you’re talking about. And then you have to explain it to somebody else – like your students.  And only then you realize that you don’t actually know what you’re talking about, because you can’t communicate it in a simple way.  I think that most ideas at least in history, maybe not in quantum mechanics, but at least in history, most ideas can be explained in a clear language even to first year students.  If you can’t do it, then there is probably something wrong with your understanding of this idea.  

A Moral Mission?

DANIEL:  I want to push you a little bit on the normative issues because I think underlying this book there is almost we might almost want to call a kind of moral mission. It seems like you want to dethrone humanity, to say to humans let’s not treat ourselves as the ultimate species with the right of dominion over the rest of the earth.  You want to say maybe we’re not that different from animals and to the extent there’s passion in the book it’s really when you discuss the way that we exploit animals in a really disgusting way.  Is that part of the mission?

YUVAL: Certainly.  I think that we have a very arrogant view of ourselves and of our place in nature.  It’s a legacy of thousands of years of religious dogmas that saw human beings as the apex of creation, and as the center of the cosmos.  Even secular, scientific people still carry this legacy with them.  Even Darwin’s Theory of Evolution and the realizations that we have evolved from apes and that we are not very different from chimpanzees didn’t really change the common view of humanity. And I think that as long as we don’t overcome this very self-centered and arrogant view of ourselves we will not be able to know the truth about ourselves and about our place in nature.

DANIEL:  And what are the direct implications for the ways we should treat animals?

YUVAL:  Most scientists now acknowledge that all mammals and birds, and perhaps other animals as well, are sentient beings.  They certainly have a mind, they have consciousness, and they have sensations and emotions.  Maybe not the full plethora of emotions characteristic of Homo sapiens but certainly many basic emotions like fear, motherly love, and anxiety are common to all mammals.  And we should therefore treat other animals, especially farm animals like pigs, cows, and chickens as sentient beings with a rich world of emotions and sensations and not as machines for producing meat, eggs, and milk.

DANIEL:  We shouldn’t eat them is one clear implication right?

YUVAL:  It’s more than just not eating them. Hunter-gatherers for example still eat animals but they don’t treat them as machines for producing meat.  I think the main problem with modern industrial farming is not only what happens to the animals in the end – namely that they are being slaughtered and eaten – rather, it’s much more the way that they are being raised and treated for months and years: locked inside tiny cages, with complete disregard not only of their physical needs but above all of their social and psychological needs.  

DANIEL:  There’s another issue in your book which a kind of normative issue.  You argue that material progress, for example in the agriculture revolution and industrial capitalism doesn’t necessarily contribute to human happiness.  In fact, it may lead to the opposite.  

YUVAL:  Until the middle of the 19th century there was a complete lack of correlation between material progress and the well-being of individual humans.  For thousands of years until about 1850 you see humans accumulating more and more power by the invention of new technologies and by new systems of organization in the economy and in politics,  but you don’t see any real improvement in the wellbeing of the average person.  If you are the emperor of China then obviously you’re much better off.  But if you’re an average Chinese peasant in 1850 it’s very, very hard to say that your life is any better than the life of hunter-gatherers in the Yangtze Valley 20,000 years ago.  You work much harder than them, your diet is worse, you suffer far more from infectious diseases, and you suffer far more from social inequality and economic exploitation.  

In the last 150 years, for the first time in history, we the daily life and the wellbeing of the average person finally started to improve in quantifiable ways.  For example there was a sharp reduction in child mortality, a reduction in violence, and in famine.  Today, for the first time in history, more people die from eating too much than from eating too little.  So finally you see some juncture between material progress and human happiness. 

At the same time, however, you also see reverse phenomena, for example, the disintegration of human communities and families. Homo sapiens is a social being, and our wellbeing depends to a large extent on the quality and depth of our social and family relations, and in the last 200 years they have been disintegrating. 

DANIEL:  So let me just ask you about the conception of wellbeing that underlies your judgments. You do criticize this idea of individual happiness of as just feeling good.  There’s a much more kind of communitarian view that well-being depends on rich social relations with family and community -is that fair to say?

YUVAL:  Definitely. This is part of human wellbeing. But even if you just look at individual human feelings, whether I feel satisfied or not, then throughout history including in the last 200 years even when objective material conditions improve people don’t necessarily feel more satisfied, because their expectations change.  Maybe you enjoy greater prosperity in objective terms but if you expect more then you might be as dissatisfied as before.  Take for example the Arab Spring revolutions. Objective material conditions in Egypt under Hosni Mubarak were much better than ever before.  There was less chance of dying from starvation,from violence or from epidemics under Mubarak than under any previous regime in Egyptian history.  Nevertheless, people were very dissatisfied and they made a revolution. And now they’re also dissatisfied with the outcome of the revolution, because they expect far more than their ancestors in ancient Egypt.  

DANIEL:  Is there a kind of Buddhist view in your book?  That the ultimate source of human happiness is when we strip ourselves of desires, is that what really motivates your view?

YUVAL:  There is indeed an influence of a Buddhist worldview. Buddhism maintains that the common reaction of the human mind to pleasure and to achievement is not satisfaction; it’s craving for more.  The same view is upheld by current biological theories.  Modern biologists agree that because of our evolutionary background, our basic reaction to achievement is not satisfaction, it’s craving for more.  This is what fuels the march of history:  humankind gains more and more power but you never see humans becoming satisfied.  

A Dark Future?

DANIEL:  Okay, now I want to ask a little bit about the future towards the end of your book that this craving for more also means that some people who are already healthy will want to crave for almost a kind of form of immortality.  Now we see that wealthy people in the future might use biotechnologies to prolong their lives and you’re worried that that’s going to lead to an increase in inequality between those that have wealth and power and the rest.  I spent the last term in Silicon Valley in Stanford and I saw a bit of that: these very wealthy, brilliant and beautiful people are craving for immortality and designing technologies that will help them achieve that.  But that might be very scary for the rest of us.  So what can be done to stop that from happening?

YUVAL:  You cannot just stop the march of technology.  People are starting to dream about overcoming old age and death because it is becoming technically feasible.  A hundred years ago or a thousand years ago this would have sounded like childish fantasy. But now with the recent breakthroughs in biotechnology, it no longer sounds so childish. Science is telling us that the reason people die is not because some God said so or because the laws of nature mandate it.  People always die because of technical problems. And every technical problem has in principle a technical solution.  And science is looking for these technical solutions.  Most scientists engaged in this enterprize won’t say, “Yes, we’re trying to overcome death.” You hear people in Silicon Valley saying that, but most doctors are too afraid to come out and admit it openly.  They only say, “Oh, I try to overcome cancer, and he’s trying to overcome AIDS, and she’s trying to overcome Alzheimer’s.”  But if you connect all the dots it’s obvious that science is now engaged in an attempt to overcome old age and death.  And, as you said, besides positive potential, it also has very scary potential.

DANIEL:  But why can’t the government regulate it so as to encourage the positive potential and discourage the negative potential?

YUVAL:  Certainly I think there is much greater scope for government regulations, especially once more people realize what’s going on. Now it’s just a Silicon Valley phenomenon, or some billionaires in Russia or China.  They begin to think that immortality is within reach. I think in 10, 20 years it will become common understanding of greater and greater parts of society and then the real political struggle will begin, because the question of old age and death will stop being a merely scientific or medical issue – it will become a very central political issue.  

But it’s a big question to what extent any political system in existence today is capable of handling the repercussions of breakthrough technologies like biotechnology and artificial intelligence.  Throughout history there has always been a delicate balance between technology and politics.  In different technological environments, different economic and political systems emerged.  Thus the Industrial Revolution destroyed all previous political systems. You couldn’t govern an industrial power like Germany or Japan the same way that you governed an agrarian medieval kingdom.   We have inherited our current political systems, whether communism or liberal democracy, from the Industrial Revolution.  And I don’t think that either of them can survive the completely different realities of biotechnology and artificial intelligence.

DANIEL:  Okay, I, let me ask you a little bit about China since we’re here. There’s a lot of scientific people at the top who can make more scientifically informed decisions on some issues like artificial intelligence.  Quite clearly, any artificial intelligence, that threatens our survival as a human species is bad and should be regulated.  I’m not sure that the U.S. system can do it, they just give like free reign to those Silicon Valley people, but maybe in China there’s greater hope, that the scientifically informed leaders can regulate those bad forms of technology. 

YUVAL:  It’s true that the way things look now, China is in a better position to regulate such things than the U.S. If you have a very centralized decision making process then you have the advantage that you can decide to regulate something, and your decision will come into effect.  The danger is that if you make the wrong decision then there are no checks and balances, and hence if you get it wrong then you get it horribly wrong.  In a system where decision making is more distributed then an error in one place is less catastrophic than in a central system.  

DANIEL:  So maybe an ideal form of government is one where there is a lot of scientifically informed decision making at the top but with mechanisms for accountability. The last question is the sort of question Nicolas [Berggruen] likes to ask when he meets great intellectuals. If you had to pick one idea that will be most influential in the next 50 years what would it be?

YUVAL: For the next 50 years it’s definitely the algorithm. The whole of science is converging on this master idea of processing data in an algorithmic way, and this will cause the whole of economics and politics to converge on the same idea.  The whole of biology since Darwin can be summarized in three words: “Organisms are algorithms.”  Simultaneously, computer scientists have been learning how to create better and better electronic algorithms.  Now these two waves – the one coming from biology and the other coming from computer science – are merging around this master concept of the algorithm, and their merger will create a tsunami that will wash everything in its way.  The basic insight which unites the biological with the electronic is that bodies and brains are also algorithms.  Hence the wall between machines and humans, between computer science and biology, is collapsing and I think the next century and probably the future of life itself will be shaped by this algorithmic view of the world.  

DANIEL:  So it might lead to forms of artificial intelligence that are smarter than we are and they might think look how you guys are treating animals, we can treat you the same way.  

YUVAL:  Exactly.  

DANIEL:  So shouldn’t we try to regulate those forms of artificial intelligence or any sort of scientific development that threatens us as human species? 

YUVAL:  We should think very hard about it and we should regulate it and we don’t have enough time. I don’t know much about the Chinese government in this respect, but certainly in Israel and from what I see in the western world in general the governments are pretty much oblivious to the danger, and they are not doing anything remotely enough about this issue.  I don’t think you can completely stop it because the basic scientific insight of the 21st century is that organisms are algorithms and that we can write algorithms artificially. This is not a genie you can put back in the bottle.  But technology’s not deterministic.  There is no determinism about where this idea would lead us in the coming decades so we should aim not just to regulate but to somehow guide this tsunami in a better and wiser direction.

Human perception of what sounds “beautiful” is necessarily biased and exclusive. If we are to truly expand our hearing apparatus, and thus our notion of beauty, we must not only shed preconceived sonic associations but also invite creative participation from beings non-human and non-living. We must also begin to cede creative control away from ourselves and toward such beings by encouraging them to exercise their own standards of beauty and collaborate with each other.

Movement I: Alarm Call
‘Alarm Call’ is a long-form composition and sound collage that juxtaposes, combines, and manipulates alarm calls from various human, non-human, and non-living beings. Evolutionary biologists understand the alarm call to be an altruistic behavior between species, who, by warning others of danger, place themselves by instinct in a broader system of belonging. The piece poses the question: how might we hear better to broaden and enhance our sense of belonging in the universe? Might we behave more altruistically if we better heed the calls of – and call out to – non-human beings?

Using granular synthesis, biofeedback, and algorithmic modulation, I fold the human alarm call – the siren – into non-human alarm calls, generating novel “inter-being” sonic collaborations with increasing sophistication and complexity. 

Movement II: A.I.-Truism
A synthesizer piece co-written with an AI in the style of Vangelis’s Blade Runner score, to pay homage to the space of the Bradbury Building.

Movement III: Alarmism
A machine learning model “learns” A.I.Truism and recreates Alarm Call, generating an original fusion of the two.

Movement IV: A.I. Call
A machine learning model “learns” Alarm Call and recreates A.I.Truism, generating an original fusion of the two.
