During the nineteenth and twentieth centuries, as humanism gained increasing social credibility and political power, it sprouted two very different offshoots: socialist humanism, which encompassed a plethora of socialist and communist movements, and evolutionary humanism, whose most famous advocates were the Nazis. Both offshoots agreed with liberalism that human experience is the ultimate source of meaning and authority.
Yuval Noah Harari
Humanism split into three main branches. The orthodox branch holds that each human being is a unique individual possessing a distinctive inner voice and a never-to-be-repeated string of experiences. Every human being is a singular ray of light, which illuminates the world from a different perspective, and which adds colour, depth and meaning to the universe.

There is today a division of labor between the elite and the masses. In medieval Europe aristocrats spent their money carelessly on extravagant luxuries whereas peasants lived frugally minding every penny. Today the tables have turned. The rich take great care managing their assets and investments, while the less well-heeled go into debt buying cars and televisions they don't really need.

In the past, censorship worked by blocking the flow of information. In the 21st century, censorship works by flooding people with irrelevant information. People just don't know what to pay attention to, and they often spend their time investigating and debating side issues.

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.

Whereas the Agricultural Revolution gave rise to theist religions, the Scientific Revolution gave birth to humanist religions, in which humans replaced gods.
Yuval Noah Harari
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 its business as usual. As far as we can tell at this point, human subjectivity would not be missed. Hence any meaning that people inscribe to their lives is just a delusion.
Yuval Noah Harari
Archaic humans paid for their large brains in two ways. Firstly, they spentmore time in search of food. Secondly, their muscles atrophied. Like a governmentdiverting money from defence to education, humans diverted energy from bicepsto neurons.
