Part One: The Cognitive Revolution
Part Two: The Agricultural Revolution
Part Three: The Unification of Humankind
Part Four: The Scientific Revolution
Afterword: The Animal that Became a God
I’m roughly following the shape of this outline for my review, so in my first post we started with the emergence of several hominid species appearing a couple of million years ago, and then traced the details of “the Cognitive Revolution” that started about 70,000 years ago, which brought Homo sapiens from a place of relative obscurity to the cusp of global dominance. In part two, I criticized Harari’s unnecessarily pessimistic view of “the Agricultural Revolution” that followed, which led to explosions in humanity’s population and global reach. (Note that the downslides that Harari pointed out about that revolution do unquestionably give us lessons that still need to be learned.) Now, in part three, Harari explores more of what he called “the single question” for understanding human history in the millennia following the Agricultural Revolution—“how did humans organize themselves in mass-cooperation networks?” He covers the seemingly inexorable trend toward unification in human societies and how the cultural phenomena of money, imperialism, and religion have enabled this. The last chapter in Part Three is basically a setup for Part Four and the role of the scientific revolution in this story, so I’ll leave that chapter for the next part of my review. Also, the chapter on religion is a doozy so I want to have plenty of space for that. As before, I’ll share quotes from the 2014 eBook and then react to each chapter along the way.

Part Three: The Unification of Humankind
Chapter 9 The Arrow of History
- (p. 181) After the Agricultural Revolution, human societies grew ever larger and more complex, while the imagined constructs sustaining the social order also became more elaborate. Myths and fictions accustomed people, nearly from the moment of birth, to think in certain ways, to behave in accordance with certain standards, to want certain things, and to observe certain rules. They thereby created artificial instincts that enabled millions of strangers to cooperate effectively. This network of artificial instincts is called ‘culture’.
- (p. 181) During the first half of the twentieth century, scholars taught that every culture was complete and harmonious, possessing an unchanging essence that defined it for all time. … Today, most scholars of culture have concluded that the opposite is true.
- (p. 184) does history have a direction? The answer is yes. Over the millennia, small, simple cultures gradually coalesce into bigger and more complex civilizations, so that the world contains fewer and fewer mega-cultures,
- (p. 185) break-ups are temporary reversals in an inexorable trend towards unity.
- (p. 191) The first millennium BC witnessed the appearance of three potentially universal orders, whose devotees could for the first time imagine the entire world and the entire human race as a single unit governed by a single set of laws. Everyone was ‘us’, at least potentially. There was no longer ‘them’. The first universal order to appear was economic: the monetary order. The second universal order was political: the imperial order. The third universal order was religious: the order of universal religions such as Buddhism, Christianity, and Islam. Merchants, conquerors, and prophets were the first people who managed to transcend the binary evolutionary division, ‘us vs them’, and to foresee the potential unity of humankind.
This story of efforts towards unification are very much in line with evolutionary history. On the home page of my website, under the section “Why Evolutionary Philosophy Matters,” I wrote:
| In 1995, John Maynard Smith and Eörs Szathmáry published a seminal book about The Major Transitions in Evolution. This book described the eight major transitions that have taken life from its simplest origins of replicating molecules all the way to its current biodiverse web of complex relations. The big takeaway from this book is that each of the 8 major transitions occurred when formerly separate and competitive biological elements figured out new ways to join up and cooperate with one another and thus begin to evolve together. The most recent major transition was the one from primate societies to human societies via the origin of language. It stands to reason, therefore, that the next great transition will come when the multitude of conflicting and competitive human societies bond together around a single shared worldview. |
There are no guarantees that we will make this next major transition. Countless other species have failed to do so. But it’s important to see this as a legitimate goal based on an urge dating back to the origin of life.

Chapter 10 The Scent of Money
- (pp. 194-5) Hunter-gatherers had no money. … only a few rare items that could not be found locally – seashells, pigments, obsidian and the like – had to be obtained from strangers. This could usually be done by simple barter … Little of this changed with the onset of the Agricultural Revolution. Most people continued to live in small, intimate communities.
- (p. 196) In a barter economy, every day the shoemaker and the apple grower will have to learn anew the relative prices of dozens of commodities. If 100 different commodities are traded in the market, then buyers and sellers will have to know 4,950 different exchange rates. And if 1,000 different commodities are traded, buyers and sellers must juggle 499,500 different exchange rates!
- (p. 201) Why are you willing to flip hamburgers, sell health insurance, or babysit three obnoxious brats when all you get for your exertions is a few pieces of colored paper? People are willing to do such things when they trust the figments of their collective imagination. Trust is the raw material from which all types of money are minted.
- (p. 207) Christians and Muslims who could not agree on religious beliefs could nevertheless agree on a monetary belief, because whereas religion asks us to believe in something, money asks us to believe that other people believe in something.
- (p. 207) For thousands of years, philosophers, thinkers and prophets have besmirched money and called it the root of all evil. Be that as it may, money is also the apogee of human tolerance.
- (p. 207) Money is based on two universal principles: a. Universal convertibility: with money as an alchemist, you can turn land into loyalty, justice into health, and violence into knowledge. b. Universal trust: with money as a go-between, any two people can cooperate on any project.
- (p. 208) When everything is convertible, and when trust depends on anonymous coins and cowry shells, it corrodes local traditions, intimate relations, and human values, replacing them with the cold laws of supply and demand. Human communities and families have always been based on belief in ‘priceless’ things, such as honor, loyalty, morality, and love. These things lie outside the domain of the market, and they shouldn’t be bought or sold for money.
Harari’s emphasis on fictions is again too strong here. It’s not that money-users “trust the figments of their collective imagination.” Rather, we all trust the laws, institutions, and behaviors that support the usage of currency. Those pieces of cooperation are very real and easy to believe in. But I do think it is extremely important to think about what is lost when Harari’s “priceless” items aren’t priced in to the regulation of markets. These externalities must be considered by societies and the governments they organize.
-------------------------
Chapter 11 Imperial Visions
- (p. 214) empire has been the world’s most common form of political organization for the last 2,500 years. Most humans during these two and a half millennia have lived in empires. Empire is also a very stable form of government. Most empires have found it alarmingly easy to put down rebellions. In general, they have been toppled only by external invasion or by a split within the ruling elite.
- (p. 218) Evolution has made Homo sapiens, like other social mammals, a xenophobic creature. Sapiens instinctively divide humanity into two parts, ‘us’ and ‘them’. ‘Us’ is people like you and me, who share our language, religion, and customs. We are all responsible for each other, but not responsible for ‘them’. We were always distinct from them, and owe them nothing.
- (p. 220) Empires have played a decisive part in amalgamating many small cultures into fewer big cultures. Ideas, people, goods and technology spread more easily within the borders of an empire than in a politically fragmented region.
- (p. 227) It is tempting to divide history neatly into good guys and bad guys, with all empires among the bad guys. For the vast majority of empires were founded on blood, and maintained their power through oppression and war. Yet most of today’s cultures are based on imperial legacies. If empires are by definition bad, what does that say about us?
- (p. 231) 200 states increasingly share the same global problems. Intercontinental ballistic missiles and atom bombs recognize no borders, and no nation can prevent nuclear war by itself. Climate change too threatens the prosperity and survival of all humans, and no government can singlehandedly stop global warming. An even greater challenge is posed by new technologies such as bioengineering and artificial intelligence. As we shall see in the last chapter, these technologies could be used to reengineer not just our weapons and vehicles, but even our bodies and minds. Indeed, they could be used to create completely new types of life forms, and change the future course of evolution. Who will decide what to do with such divine powers of creation? It is unlikely that humankind can deal with these challenges without global cooperation. It remains to be seen how such cooperation could be secured. Perhaps global cooperation can only be secured through violent clashes and the imposition of a new conquering empire. Perhaps humans could find a more peaceful way to unite. For 2,500 years, since Cyrus the Great, numerous empires promised to build a universal political order for the benefit of all humans. They all lied, and they all failed. No empire was truly universal, and no empire really served the benefit of all humans. Will a future empire do better?
Let’s hope so! Our evolutionary urges are directed towards both competition AND cooperation, and the principles of cooperation exist and are now well known. It is up to us, however, to regulate human societies in a way to promote this rather than to allow the strong to dominate the weak to the detriment of all.
-------------------------
Chapter 12 The Law of Religion
- (p. 234) Today religion is often considered a source of discrimination, disagreement, and disunion. Yet, in fact, religion has been the third great unifier of humankind, alongside money and empires.
- (p. 234) Religion can thus be defined as a system of human laws that is founded on a belief in superhuman laws. This involves two distinct criteria: 1. Religion is an entire system of laws, rather than an isolated custom or belief. … 2. To be considered a religion, the system of laws must claim to be based on superhuman laws rather than on human decisions.
- (p. 235) a religion must possess two further qualities. First, it must espouse a universal superhuman order that is true always and everywhere. Second, it must insist on spreading this belief to everyone.
- (p. 235) As far as we know, universal and missionary religions began to appear only in the first millennium BC. Their emergence was one of the most important revolutions in history, and made a vital contribution to the unification of humankind
- (p. 236) How then to safeguard the fecundity of the flocks? A leading theory about the origin of the gods argues that gods gained importance because they offered a solution to this problem. Gods such as the fertility goddess, the sky god, and the god of medicine took center stage when plants and animals lost their ability to speak, and the gods’ main role was to mediate between humans and the mute plants and animals.
- (p. 237) Animists thought that humans were just one of many creatures inhabiting the world. Polytheists, on the other hand, increasingly saw the world as a reflection of the relationship between gods and humans.
- (p. 238) The fundamental insight of polytheism, which distinguishes it from monotheism, is that the supreme power governing the world is devoid of interests and biases, and therefore it is unconcerned with the mundane desires, cares, and worries of humans.
- (p. 239) once you start dividing up the all-encompassing power of a supreme principle, you’ll inevitably end up with more than one deity. Hence the plurality of gods. The insight of polytheism is conducive to far-reaching religious tolerance.
- (p. 240) The only god that the Romans long refused to tolerate was the monotheistic and evangelizing god of the Christians.
- (p. 240) In the 300 years from the crucifixion of Christ to the conversion of Emperor Constantine, polytheistic Roman emperors initiated no more than four general persecutions of Christians. Local administrators and governors incited some anti-Christian violence of their own. Still, if we combine all the victims of all these persecutions, it turns out that in these three centuries, the polytheistic Romans killed no more than a few thousand Christians. In contrast, over the course of the next 1,500 years, Christians slaughtered Christians by the millions to defend slightly different interpretations of the religion of love and compassion.
- (p. 245) Polytheism gave birth not merely to monotheist religions, but also to dualistic ones. Dualistic religions espouse the existence of two opposing powers: good and evil.
- (p. 246) monotheism explains order, but is mystified by evil. Dualism explains evil, but is puzzled by order. There is one logical way of solving the riddle: to argue that there is a single omnipotent God who created the entire universe—and He’s evil. But nobody in history has had the stomach for such a belief.
- (p. 249) During the first millennium BC, religions of an altogether new kind began to spread through Afro-Asia. The newcomers, such as Jainism and Buddhism in India, Daoism and Confucianism in China, and Stoicism, Cynicism and Epicureanism in the Mediterranean basin, were characterized by their disregard of gods.
- (p. 250) [Siddhartha Gautama] spent six years meditating on the essence, causes, and cures for human anguish. In the end he came to the realization that suffering is not caused by ill fortune, by social injustice, or by divine whims. Rather, suffering is caused by the behavior patterns of one’s own mind. Gautama’s insight was that no matter what the mind experiences, it usually reacts with craving, and craving always involves dissatisfaction.
- (p. 250) even when we experience pleasant things we are never content. We either fear that the pleasure might disappear, or we hope that it will intensify.
- (p. 252) craving is replaced by a state of perfect contentment and serenity, known as nirvana (the literal meaning of which is ‘extinguishing the fire’).
- (p. 252) This law, known as dharma or dhamma, is seen by Buddhists as a universal law of nature. That ‘suffering arises from craving’ is always and everywhere true, just as in modern physics E always equals mc2.
- (p. 254) The modern age has witnessed the rise of a number of new natural-law religions, such as liberalism, Communism, capitalism, nationalism, and Nazism. These creeds do not like to be called religions, and refer to themselves as ideologies. But this is just a semantic exercise. If a religion is a system of human norms and values that is founded on belief in a superhuman order, then Soviet Communism was no less a religion than Islam.
- (p. 256) Humanist religions sanctify humanity, or more correctly, Homo sapiens. Humanism is a belief that Homo sapienshas a unique and sacred nature, which is fundamentally different from the nature of all other animals and of all other phenomena. Humanists believe that the unique nature of Homo sapiens is the most important thing in the world, and it determines the meaning of everything that happens in the universe. The supreme good is the good of Homo sapiens. The rest of the world and all other beings exist solely for the benefit of this species.
- (p. 256) Humanism has split into three rival sects that fight over the exact definition of ‘humanity’
- (p. 257) Today, the most important humanist sect is liberal humanism, which believes that ‘humanity’ is a quality of individual humans, and that the liberty of individuals is therefore sacrosanct.
- (p. 257) If we encounter an ethical or political dilemma, we should look inside and listen to our inner voice – the voice of humanity. The chief commandments of liberal humanism are meant to protect the liberty of this inner voice against intrusion or harm. These commandments are collectively known as ‘human rights’.
- (p. 257) Even though liberal humanism sanctifies humans, it does not deny the existence of God, and is, in fact, founded on monotheist beliefs. The liberal belief in the free and sacred nature of each individual is a direct legacy of the traditional Christian belief in free and eternal individual souls.
- (p. 258) Another important sect is socialist humanism. Socialists believe that ‘humanity’ is collective rather than individualistic. They hold as sacred not the inner voice of each individual, but the species Homo sapiens as a whole.
- (p. 258) According to socialists, inequality is the worst blasphemy against the sanctity of humanity, because it privileges peripheral qualities of humans over their universal essence.
- (p. 258) socialist humanism is built on monotheist foundations. The idea that all humans are equal is a revamped version of the monotheist conviction that all souls are equal before God.
- (p. 258) The only humanist sect that has actually broken loose from traditional monotheism is evolutionary humanism, whose most famous representatives were the Nazis. What distinguished the Nazis from other humanist sects was a different definition of ‘humanity’, one deeply influenced by the theory of evolution. In contrast to other humanists, the Nazis believed that humankind is not something universal and eternal, but rather a mutable species that can evolve or degenerate. Man can evolve into superman, or degenerate into a subhuman.
- (p. 261) following the logic of Darwinian evolution, they argued that natural selection must be allowed to weed out unfit individuals and leave only the fittest to survive and reproduce
- (p. 261) the fittest humans would inevitably drown in a sea of unfit degenerates. Humankind would become less and less fit with each passing generation – which could lead to its extinction.
- (p. 261) A 1942 German biology textbook explains in the chapter ‘The Laws of Nature and Mankind’ that the supreme law of nature is that all beings are locked in a remorseless struggle for survival. … the textbook concludes that “These natural laws are incontrovertible; living creatures demonstrate them by their very survival. They are unforgiving. Those who resist them will be wiped out. Biology not only tells us about animals and plants, but also shows us the laws we must follow in our lives, and steels our wills to live and fight according to these laws. The meaning of life is struggle. Woe to him who sins against these laws.”
- (p. 262) Then follows a quotation from Mein Kampf: ‘The person who attempts to fight the iron logic of nature thereby fights the principles he must thank for his life as a human being. To fight against nature is to bring about one’s own destruction.’
- (p. 263) At the dawn of the third millennium, the future of evolutionary humanism is unclear.
Wow, that stuff about humanism is atrocious and a lot has already been written about it. My philosopher friend and fellow Humanist Andy Norman published an exchange with Harari about this in Free Inquiry. And I commented further on it in my long post “In Defence of Humanism”, which I wrote while I was a trustee of North East Humanists. I will just add here that I think of evolutionary philosophy as a worldview rather than a religion, but I do hope it represents a much better alternative for the future of evolutionary humanism than Harari seems to think is possible.
As for the history of more traditional religions, Harari is right that they have certainly acted as unifying forces for large segments of the world population. However, due to their insistence on owning revealed truths, which also happen to be in conflict with one another, these religions are now intractable barriers to the further coming together of humans. (Unless, of course, one religion wipes out all the other ones in a genocide far worse than the latest attempt.) In evolutionary terms, this means the world’s major religions have become stranded on local peaks in a fitness landscape where there is actually a much higher possibility out there for Homo sapiens and the rest of life. To reach that peak, many will have to come down off their perches and make the trek to a truly unifying vision for the world. I’m not holding my breath for that to happen anytime soon, but I’ll keep working on building that new peak in the hopes that it will attract others eventually.
Next up, another great unifying force for the world—the scientific revolution. I’ll be back soon to cover that in part four of these reviews.
