Yuval Noah Harari
“In the wake of the Cognitive Revolution, gossip helped Homo sapiens to form larger and more stable bands. But even gossip has its limits. Sociological research has shown that the maximum ‘natural’ size of a group bonded by gossip is about 150 individuals. Most people can neither intimately know, nor gossip effectively about, more than 150 human beings.”

“This is the essence of the Agricultural Revolution: the ability to keep more people alive under worse conditions.”

“One of history’s few iron laws is that luxuries tend to become necessities and to spawn new obligations.”
Yuval Noah Harari, Sapiens: A Brief History of Humankind

Yuval Noah Harari
“For more than 2 million years, human neural networks kept growing and growing, but apart from some flint knives and pointed sticks, humans had precious little to show for it. What then drove forward the evolution of the massive human brain during those 2 million years? Frankly, we don’t know.”
Yuval Noah Harari, Sapiens: A Brief History of Humankind

Yuval Noah Harari
“Tolerance is not a Sapiens trademark. In modern times, a small difference in skin colour, dialect or religion has been enough to prompt one group of Sapiens to set about exterminating another group. Would ancient Sapiens have been more tolerant towards an entirely different human species? It may well be that when Sapiens encountered Neanderthals, the result was the first and most significant ethnic-cleansing campaign in history.”
