Sapiens Quotes

Large numbers of strangers can cooperate successfully by believing in common myths.

In what way can we say that Peugeot SA (the company’s official name) exists? There are many Peugeot vehicles, but these are obviously not the company. Even if every Peugeot in the world were simultaneously junked and sold for scrap metal, Peugeot SA would not disappear. It would continue to manufacture new cars and issue its annual report. […] Peugeot has managers and shareholders, but neither do they constitute the company. All the managers could be dismissed and all its shares sold, but the company itself would remain intact […] In short, Peugeot SA seems to have no essential connection to the physical world. Does it really exist? Peugeot is a figment of our collective imagination.

While people in today’s affluent societies work an average of forty to forty-five hours a week, and people in the developing world work sixty and even eighty hours a week, hunter-gatherers living today in the most inhospitable of habitats—such as the Kalahari Desert—work on average for just thirty-five to forty-five hours a week. […] It may well be that ancient hunter-gatherers living in zones more fertile than the Kalahari spent even less time obtaining food and raw materials. On top of that, foragers enjoyed a lighter load of household chores. They had no dishes to wash, no carpets to vacuum, no floors to polish, no nappies to change and no bills to pay.

The forager economy provided most people with more interesting lives than agriculture or industry do. Today, a Chinese factory hand leaves home around seven in the morning, makes her way through polluted streets to a sweatshop, and there operates the same machine, in the same way, day in, day out, for ten long and mind-numbing hours, returning home around seven in the evening in order to wash dishes and do the laundry.

The typical peasant in traditional China ate rice for breakfast, rice for lunch, and rice for dinner. If she were lucky, she could expect to eat the same on the following day. By contrast, ancient foragers regularly ate dozens of different foodstuffs. […] This variety ensured that the ancient foragers received all the necessary nutrients.

Moreover, most people in agricultural and industrial societies lived in dense, unhygienic permanent settlements—ideal hotbeds for disease. Foragers roamed the land in small bands that could not sustain epidemics.

[T]he historical record makes Homo sapiens look like an ecological serial killer.

If things continue at the present pace, it is likely that whales, sharks, tuna and dolphins will follow the diprotodons, ground sloths and mammoths to oblivion. Among all the world’s large creatures, the only survivors of the human food will be humans themselves, and the farmyard animals that serve as galley slaves in Noah Ark.

Why would any sane person lower his or her standard of living just to multiply the number of copies of the Homo sapiens genome? Nobody agreed to this deal: the Agricultural Revolution was a trap.

Over the last few decades, we have invented countless time-saving devices that are supposed to make life more relaxed—washing machines, vacuum cleaners, dishwashers, telephones, mobile phones, computers, email. Previously it took a lot of work to write a letter, address and stamp an envelope, and take it to the mailbox. It took days or weeks, maybe even months, to ger a reply. Nowadays I can dash off an email, send it halfway around the globe, and (if my addressee is online) receive a reply a minute later. I’ve saved all that trouble and time, but do I live a more relaxed life?

Domesticated chickens and cattle may well be an evolutionary success story, but they are also among the most miserable creatures that ever lived. The domestication of animals was founded on a series of brutal practices that only became crueller with the passing of the centuries. The natural lifespan of wild chickens is about seven to twelve years, and of cattle about twenty to twenty-five years. In the wild, most chickens and cattle died long before that, but they still had a fair chance of living for a respectable number of years. In contrast, the vast majority of domesticated chickens and cattle are slaughtered at the age of between a few weeks and a few months, because this has always been the optimal slaughtering age from an economic perspective.

Consequently, from the very advent of agriculture, worries about the future became major players in the theatre of the human mind. Where farmers depended on rains to water their fields, the onset of the rainy season meant that each morning the farmers gazed towards the horizon, sniffing the wind and straining their eyes. Is that a cloud? Would the rains come on time? Would there be enough? Would violent storms wash the seeds from the fields and batter down seedlings?

Hammurabi’s Code asserts that Babylonian social order is rooted in universal and eternal principles of justice, dictated by the gods.

The imagined orders sustaining these networks were neither neutral nor fair. They divided people into make-believe groups, arranged in a hierarchy. The upper levels enjoyed privileges and power while the lower ones suffered from discrimination and oppression. Hammurabi’s Code, for example, established a pecking order of superiors, commoners and slaves. Superiors got all the good things in life. Commoners got what was left. Slaves got a beating if they complained.

People continued to speak mutually incomprehensible languages, obey different rulers and worship distinct gods, but all believed in […] gold and silver coins. Without this shared belief, global trading networks would have been virtually impossible.

The Scientific Revolution has not been a revolution of knowledge. It has been above all a revolution of ignorance. The great discovery that launched the Scientific Revolution was the discovery that humans do not know the answers to their most important questions. Premodern traditions of knowledge such as Islam, Christianity, Buddhism, and Confucianism asserted that everything that is important to know about the world was already known […] It was inconceivable that the Bible, the Qur’an or the Vedas were missing out on a crucial secret of the universe—a secret that might yet be discovered by flesh-and-blood creatures.

Mere observations, however, are not knowledge. In order to understand the universe, we need to connect observations into comprehensive theories. Earlier traditions usually formulated their theories in terms of stories. Modern science uses mathematics.

Throughout most of history, mathematics was an esoteric field that even educated people rarely studied seriously. In medieval Europe, logic, grammar and rhetoric formed the educational core, while the teaching of mathematics seldom went beyond simple arithmetic and geometry. Nobody studied statistics. The undisputed monarch of all sciences was theology. Today few students study rhetoric; logic is restricted to philosophy departments, and theology to seminaries.

Consider the following quandary: two biologists from the same department, possessing the same professional skills, have both applied for a million-dollar grant to finance their current research projects. […] Assuming that the amount of money is limited, and that it is impossible to finance both research projects, which one should be funded? There is no scientific answer to this question. There are only political, economic and religious answers.

Henceforth not only European geographers, but European scholars in almost all other fields of knowledge began to draw maps with spaces left to fill in. They began to admit that their theories were not perfect and that there were important things that they did not know.

Scientific research is usually funded by either governments or private businesses. When capitalist governments and businesses consider investing in a particular scientific project, the first questions are usually, ‘Will this project enable us to increase production and profits? Will it produce economic growth?’ A project that can’t clear these hurdles has little chance of finding a sponsor. No history of modern science can leave capitalism out of the picture.

Follow-up research showed that Harlow’s orphaned monkeys grew up to be emotionally disturbed even though they had received all the nourishment they required.

If happiness is determined by expectations, then two pillars of our society—mass media and the advertising industry—may unwittingly be depleting the globe's reservoirs of contentment. If you were an eighteen-year-old youth in a small village 5,000 years ago you'd probably think you were good-looking because there were only fifty other men in your village and most of them were either old, scarred and wrinkled, or still little kids. But if you are a teenager today you are a lot more likely to feel inadequate. Even if the other guys at school are an ugly lot, you don’t measure yourself against them but against the movie stars, athletes and supermodels you see all day on television, Facebook and giant billboards.

It’s unclear whether bioengineering could really resurrect the Neanderthals, but it would very likely bring down the curtain on Homo sapiens. Tinkering with our genes won’t necessarily kill us. But we might fiddle with Homo sapiens to such an extent that we would no longer be Homo sapiens.

Unfortunately, the Sapiens regime on earth has so far produced little that we can be proud of. We have mastered our surroundings, increased food production, built cities, established empires and created far-flung trade networks. But did we decrease the amount of suffering in the world? Time and again, massive increases in human power did not necessarily improve the well-being of individual Sapiens, and usually caused immense misery to other animals.
