Sapiens: A Brief History of Humankind
by Yuval Noah Harari · 2011
Sapiens argues that Homo sapiens achieved global dominance not through superior strength or intelligence, but through a unique cognitive ability: the power to believe in shared myths. Money, nations, human rights, corporations—none exist in nature. They are fictions we collectively believe in, and that collective belief is the source of all large-scale human cooperation.
Harari divides history into three revolutions. The Cognitive Revolution (70,000 years ago) gave us flexible language and the ability to communicate about things that don't exist. The Agricultural Revolution (12,000 years ago) was, controversially, "history's biggest fraud"—it made civilisation possible but made individual lives harder. The Scientific Revolution (500 years ago) combined with capitalism and imperialism to create the modern world.
The book ends with a disturbing question: are we happier? Despite our power over nature and our extended lifespans, Harari suggests the evidence is unclear—and that a species capable of remaking the world might not know what it actually wants.
