In 1989, with the end of the Cold War and the collapse of communism, it seemed that the liberal story had won. The liberal story says that humankind is inevitably marching towards a global society of free markets and democratic politics.
Ignorance is not too dangerous. If you combine it with power, then this is a toxic mix.
People already have bionic arms and legs that work by the power of thought. And we increasingly outsource mental and communicative activities to computers. We are merging with our smartphones. Very soon, they will just be part of the body.
If you think about the great religions that have united large parts of humankind, people believe gods are very concrete - there is an angry old man in the sky, and if I do something wrong, he will punish me.
We control the world basically because we are the only animals that can cooperate flexibly in very large numbers. And if you examine any large-scale human cooperation, you will always find that it is based on some fiction like the nation, like money, like human rights.
We are all living together on a single planet, which is threatened by our own actions. And if you don't have some kind of global cooperation, nationalism is just not on the right level to tackle the problems, whether it's climate change or whether it's technological disruption.
All the major problems of the world today are global in essence, and they cannot be solved unless through some kind of global cooperation. It's not just climate change, which is, like, the most obvious example people give. I think more in terms of technological disruption.
The key to victory lies more in manipulation and cooperation than in exceptional personal skills.
The basic human reaction to pleasure is not satisfaction, but rather craving for more. Hence, no matter what we achieve, it only increases our craving, not our satisfaction.
I'm vegan, though not completely religious about it. While writing 'Sapiens,' I became familiar with how we treat animals in the meat and dairy industries. I was so horrified that I didn't want to be a part of it anymore.
The most dangerous thing about terrorism is the over-reaction to it.
Increasingly, our decisions will be made by the algorithms that surround us. Whenever there is a big dilemma, you just ask Google what to do. And what kind of life is that?
We can suspend disbelief about Harry Potter, and we do the same thing with God, and we do the same thing with human rights, and we do the same thing with money.
You go to a Japanese restaurant and have a wonderful dish, and the thing to do is take a picture with your phone, put it on Facebook, and see how many likes you get. If you don't share your experiences, they don't become part of the data processing system, and they have no meaning.
We did not domesticate wheat; wheat domesticated us.
Animals are the main victims of history, and the treatment of domesticated animals in industrial farms is perhaps the worst crime in history.
Those who refuse to liberalise and globalise are doomed to failure.
Everybody since the '60s has been saying the nation is a fiction - the nation is an imaginary unity - but people didn't connect the dots and say all human endeavours sprang from the same principle.
It's very, very difficult to reinvent yourself when you're 40 or 50, whether you are a taxi driver who now needs to become a web designer, or anything else. It just becomes more difficult and more scary.
My main ambition as a historian is to figure out what's really happening in the world, instead of the fictions that humans have been creating for thousands of years in order to explain or control what's happening in the world.
