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.

Humans are extremely good in acquiring new power, but they are not very good in translating this power into greater happiness, which is why we are far more powerful than ever before but we don't seem to be much happier.

Ignorance is not too dangerous. If you combine it with power, then this is a toxic mix.

Yuval Noah Harari Quotes
