Sapiens: A Brief History of Humankind

by Yuval Noah Harari

Sapiens by contrast is more like a banana republic dictator. Having so recently been one of the underdogs of the savannah, we are full of fears and anxieties over our position, which makes us doubly cruel and dangerous. Many historical calamities, from deadly wars to ecological catastrophes, have resulted from this over-hasty jump.

Whereas chimpanzees spend five hours a day chewing raw food, a single hour suffices for people eating cooked food.

Lawyers call this a ‘legal fiction’. It can’t be pointed at; it is not a physical object. But it exists as a legal entity. Just like you or me, it is bound by the laws of the countries in which it operates. It can open a bank account and own property. It pays taxes, and it can be sued and even prosecuted separately from any of the people who own or work for it.

Telling effective stories is not easy. The difficulty lies not in telling the story, but in convincing everyone else to believe it. Much of history revolves around this question: how does one convince millions of people to believe particular stories about gods, or nations, or limited liability companies? Yet when it succeeds, it gives Sapiens immense power, because it enables millions of strangers to cooperate and work towards common goals.

Average life expectancy was apparently just thirty to forty years, but this was due largely to the high incidence of child mortality. Children who made it through the perilous first years had a good chance of reaching the age of sixty, and some even made it to their eighties.

Voltaire said about God that ‘there is no God, but don’t tell that to my servant, lest he murder me at night’.

Diogenes, the Greek philosopher who founded the Cynical school, lived in a barrel. When Alexander the Great once visited Diogenes as he was relaxing in the sun, and asked if there were anything he might do for him, the Cynic answered the all-powerful conqueror, ‘Yes, there is something you can do for me. Please move a little to the side. You are blocking the sunlight.’

The name ‘denarius’ became a generic name for coins. Muslim caliphs Arabicised this name and issued ‘dinars’. The dinar is still the official name of the currency in Jordan, Iraq, Serbia, Macedonia, Tunisia and several other countries.

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. Money is more open-minded than language, state laws, cultural codes, religious beliefs and social habits. Money is the only trust system created by humans that can bridge almost any cultural gap, and that does not discriminate on the basis of religion, gender, race, age or sexual orientation. Thanks to money, even people who don’t know each other and don’t trust each other can nevertheless cooperate effectively.

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.

The real test of ‘knowledge’ is not whether it is true, but whether it empowers us.

In the months leading up to their expedition, the Apollo 11 astronauts trained in a remote moon-like desert in the western United States. The area is home to several Native American communities, and there is a story – or legend – describing an encounter between the astronauts and one of the locals. One day as they were training, the astronauts came across an old Native American. The man asked them what they were doing there. They replied that they were part of a research expedition that would shortly travel to explore the moon. When the old man heard that, he fell silent for a few moments, and then asked the astronauts if they could do him a favour. ‘What do you want?’ they asked. ‘Well,’ said the old man, ‘the people of my tribe believe that holy spirits live on the moon. I was wondering if you could pass an important message to them from my people.’ ‘What’s the message?’ asked the astronauts. The man uttered something in his tribal language, and then asked the astronauts to repeat it again and again until they had memorised it correctly. ‘What does it mean?’ asked the astronauts. ‘Oh, I cannot tell you. It’s a secret that only our tribe and the moon spirits are allowed to know.’ When they returned to their base, the astronauts searched and searched until they found someone who could speak the tribal language, and asked him to translate the secret message. When they repeated what they had memorised, the translator started to laugh uproariously. When he calmed down, the as...

There is poetic justice in the fact that a quarter of the world, and two of its seven continents, are named after a little-known Italian whose sole claim to fame is that he had the courage to say, ‘We don’t know.’

Take up the White Man’s burden – Send forth the best ye breed – Go bind your sons to exile To serve your captives’ need; To wait in heavy harness, On fluttered folk and wild – Your new-caught, sullen peoples, Half-devil and half-child.

in terms of historical differences between cultures rather than biological differences between races. We no longer say, ‘It’s in their blood.’ We say, ‘It’s in their culture.’

Credit enables us to build the present at the expense of the future.

The rich were obliged to do penance for their evil deeds by giving some of their surplus wealth to charity.

So it was hard to get a loan in the premodern world, and when you got one it was usually small, short-term, and subject to high interest rates.

The idea of progress is built on the notion that if we admit our ignorance and invest resources in research, things can improve.

In order to control trade on the important Hudson River, WIC built a settlement called New Amsterdam on an island at the river’s mouth. The colony was threatened by Native Americans and repeatedly attacked by the British, who eventually captured it in 1664. The British changed its name to New York. The remains of the wall built by WIC to defend its colony against Native Americans and British are today paved over by the world’s most famous street – Wall Street.

Around the time that Homo sapiens was elevated to divine status by humanist religions, farm animals stopped being viewed as living creatures that could feel pain and distress, and instead came to be treated as machines.

This is the basic lesson of evolutionary psychology: a need shaped in the wild continues to be felt subjectively even if it is no longer really necessary for survival and reproduction.

Many call this process ‘the destruction of nature’. But it’s not really destruction, it’s change. Nature cannot be destroyed. Sixty-five

In 1784 a carriage service with a published schedule began operating in Britain. Its timetable specified only the hour of departure, not arrival. Back then, each British city and town had its own local time, which could differ from London time by up to half an hour. When it was 12:00 in London, it was perhaps 12:20 in Liverpool and 11:50 in Canterbury. Since there were no telephones, no radio or television, and no fast trains – who could know, and who cared?2

The figures for 2002 are even more surprising. Out of 57 million dead, only 172,000 people died in war and 569,000 died of violent crime (a total of 741,000 victims of human violence). In contrast, 873,000 people committed suicide.5 It turns out that in the year following the 9/11 attacks, despite all the talk of terrorism and war, the average person was more likely to kill himself than to be killed by a terrorist, a soldier or a drug dealer.

As Nietzsche put it, if you have a why to live, you can bear almost any how.
