For thousands of years, we have gained the power to control the world outside us but not to control the world inside. You could stop a river from flowing, but you could not stop your body from becoming old. You could kill mosquitoes, but you could not kill annoying thoughts buzzing inside your head.
Interpretation
The quote highlights the limits of human mastery over internal struggles compared to external control.
Yuval Noah Harari's quote reflects on humanity's long-standing ability to manipulate the external environment through technology and civilization, while emphasizing the profound difficulty of mastering our own internal thoughts and emotions. He draws a powerful analogy between controlling natural elements and the relentless passage of time and the complexities of the human mind, suggesting that despite our advancements, we often remain prisoners of our own inner turmoil.
In practice
In a discussion on mental health, this quote can serve to express the struggle of managing thoughts.
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.
I titled the book 'Homo Deus' because we really are becoming gods in the most literal sense possible. We are acquiring abilities that have always been thought to be divine abilities - in particular, the ability to create life. And we can do with that whatever we want.
The notion of superhumans is using bioengineering and artificial intelligence to upgrade human abilities. If they use the power to change themselves, to change their own minds, their own desires, then we have no idea what they will want to do.
Techno-humanism aims to amplify the power of humans, creating cyborgs and connecting humans to computers, but it still sees human interests and desires as the highest authority in the universe.
The most important question in 21st-century economics may well be, 'What should we do with all the superfluous people, once we have highly intelligent non-conscious algorithms that can do almost everything better than humans?'
Take Google Maps or Waze. On the one hand, they amplify human ability - you are able to reach your destination faster and more easily. But at the same time, you are shifting the authority to the algorithm and losing your ability to find your own way.
The way you live your days is the way you live your life.
For nothing is more democratic than logic; it is no respecter of persons and makes no distinction between crooked and straight noses.
In any civilized society, it is every citizen's responsibility to obey just laws. But at the same time, it is every citizen's responsibility to disobey unjust laws.
Conquest is not in our principles. It is inconsistent with our government.
Oddly, I feel more protected when I write in Italian, even though I'm also more exposed.
This demand follows from an insight that I was the first to articulate: that there are no moral facts.
