FAQ
What is the main argument of Sapiens?
Harari argues that Homo sapiens became the dominant species because of our unique ability to believe in "intersubjective realities"—shared fictions like money, nations, religions, and human rights. These imagined orders allow millions of strangers to cooperate, something no other species can do.
Why does Harari call agriculture "history's biggest fraud"?
While agriculture increased total food production, it actually made individual lives harder: longer work hours, less varied diets, more disease from living with animals, and social hierarchies. We didn't domesticate wheat—wheat domesticated us, tying us to land and grueling labor.
What are the three revolutions in Sapiens?
1) Cognitive Revolution (70,000 years ago): Language and abstract thinking. 2) Agricultural Revolution (10,000 years ago): Farming and permanent settlements. 3) Scientific Revolution (500 years ago): Systematic pursuit of knowledge, capitalism, and technological progress.
