Yuval Noah Harari: What explains the rise of humans? (script)
Summary
This was quite a shocking talk for me though I've understood why Japanese people think that Some Japan is not a good country.
It is because a state and a nation are not objective realities. This is just a story that people have invented and become extremely attached to. I like that the speaker says what he wants to say clearly because Japanese people don't do that.
The story comes from the difference between the ability of humans and all other animals, and this is the reason for the rise of humans.
The different ability between humans and all other animals is on the collective level that only humans have. It maks humans flexibly cooperate with each other in very large numbers. All other animals cannot do in a sudden new opportunity or in a new danger, and they cannot reinvent social system overnight. Even if some animals can flexibly cooperate, they do only in small numbers.
The reason why only humans can do it is their imagination. Thus, they can flexibly cooperate with countless number of strangers but they can create and believe fictional stories. That's why they obey and follow the same rules, norms, and values. This mechanism creates human rights, our state and nations, and money. In fact, these are just fictional stories that humans have invented. In history, this fictional reality became more and more powerful and humans control the world now. This is the rise of humans. The rise is the noun and it means that the process of becoming very famous, powerful, or popular.
Then the fictional reality seems to lead us to dividing the rich and the poor now. It's never said a good thing but the power will become stronger and stronger.
I think that current Japanese stories are seen
only governments to get a benefit. In the world, we can have a better imagination because we have an ability of that collective level.
