culture forbid unnatural biological prohibition

A truly unnatural behaviour, one that goes against the laws of nature, simply cannot exist, so it would need no prohibition.”

― Yuval Noah Harari

sapiens rule world web meaning common imagination

“Sapiens rule the world because only they can weave an intersubjective web of meaning: a web of laws, forces, entities and places that exist purely in their common imagination. This web allows humans alone to organise crusades, socialist revolutions and human rights movements.”

“Every day millions of people decide to grant their smartphone a bit more control over their lives or try a new and more effective antidepressant drug.

scientific discovery ignorance knowledge progress world science

super-intelligent cyborg ordinary human animal cousin

paradox history knowledge vhange behaiour data outdated

“This is the paradox of historical knowledge. Knowledge that does not change behaviour is useless. But knowledge that changes behaviour quickly loses its relevance. The more data we have and the better we understand history, the faster history alters its course, and the faster our knowledge becomes outdated.”

― Yuval Noah Harari

scientists direction want thinking thought

“The only thing we can try to do is to influence the direction scientists are taking. Since we might soon be able to engineer our desires too, perhaps the real questions facing us is not 'What do we want to become?', but "What do we want to want?' Those who are not spooked by this question probably haven't given it enough thought.”

― Yuval Noah Harari

“Obesity is a double victory for consumerism. Instead of eating little, which will lead to economic contraction, people eat too much and then buy diet products - contributing to economic growth twice over.”

― Yuval Noah Harari

science viewpoint human life meaning evolution cosmic

“As far as we can tell, from a purely scientific viewpoint, human life has absolutely no meaning. Humans are the outcome of blind evolutionary processes that operate without goal or purpose. Our actions are not part of some divine cosmic plan, and if planet Earth were to blow up tomorrow morning, the universe would probably keep going about business as usual.”

“Scientists generally agree that no theory is 100 percent correct. Thus, the real test of knowledge is not truth, but utility. Science gives us power. The more useful that power, the better the science.”

― Yuval Noah Harari

teacher information unimportant

"…the last thing a teacher needs to give her pupils is more information. They already have far too much of it. Instead, people need the ability to make sense of information, to tell the difference between what is important and what is unimportant, and, above all, to combine many bits of information into a broad picture of the world."
