Sapiens: A Brief History of Humankind

by Yuval Noah Harari

Just as human politicians on election campaigns go around shaking hands and kissing babies, so aspirants to the top position in a chimpanzee group spend much time hugging, back-slapping and kissing baby chimps.

Yet none of these things exists outside the stories that people invent and tell one another. There are no gods in the universe, no nations, no money, no human rights, no laws and no justice outside the common imagination of human beings.

One of history’s few iron laws is that luxuries tend to become necessities and to spawn new obligations.

With each passing generation, the sheep became fatter, more submissive and less curious. Voilà! Mary had a little lamb and everywhere that Mary went the lamb was sure to go.

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.

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.
