Yuval Noah Harari wrote in “Sapiens: A Brief History of Humankind” that Homo sapiens rules the world because it is the only animal that can believe in things that exist purely in its own imagination, such as gods, states, money and human rights.
Here are two quotes on money from his TED talk about the book.
“Again, money is not an objective reality; it has no objective value. Take this green piece of paper, the dollar bill. Look at it — it has no value. You cannot eat it, you cannot drink it, you cannot wear it. But then came along these master storytellers — the big bankers, the finance ministers, the prime ministers — and they tell us a very convincing story: “Look, you see this green piece of paper? It is actually worth 10 bananas.” And if I believe it, and you believe it, and everybody believes it, it actually works. I can take this worthless piece of paper, go to the supermarket, give it to a complete stranger whom I’ve never met before, and get, in exchange, real bananas which I can actually eat.”
“Money, in fact, is the most successful story ever invented and told by humans because it is the only story everybody believes. Not everybody believes in God, not everybody believes in human rights, not everybody believes in nationalism, but everybody believes in money and in the dollar bill.”
