Sapiens: A Brief History of Humankind by Yuval Noah Harari is a groundbreaking narrative of humanity's creation and evolution that explores the ways in which biology and history have defined us and enhanced our understanding of what it means to be "human."
The Cognitive Revolution (c. 70,000 BCE)
Harari argues that Homo sapiens came to dominate the world because it is the only animal that can cooperate flexibly in large numbers. This can be done because Sapiens can believe in things that exist purely in the imagination, such as gods, nations, money, and human rights. He calls this the "Cognitive Revolution".
The Agricultural Revolution (c. 10,000 BCE)
The transition from foraging to farming is described by Harari as "history's biggest fraud". While it allowed populations to grow, it led to a worse diet, longer working hours, and greater risk of starvation and disease for the average individual. It also led to the domestication of animals, which Harari describes as a catastrophe for the animals involved.
The Unification of Humankind
Over time, human cultures have been merging. Harari identifies three great unifiers: money, empires, and universal religions. These forces have brought the world closer together, creating a global village.
- Money: The most universal and efficient system of mutual trust ever devised.
- Empires: Political orders that rule over a significant number of distinct peoples and possess flexible borders and a potentially unlimited appetite.
- Religions: Systems of human norms and values that are founded on a belief in a superhuman order.
The Scientific Revolution (c. 1500 CE)
The Scientific Revolution began when humans admitted their ignorance and started to acquire new powers through observation and mathematics. This revolution has led to unprecedented economic growth and technological advancement, but also to new ethical dilemmas.
The Future of Sapiens
Harari concludes by speculating on the future of our species. He suggests that we are on the verge of becoming "gods", capable of designing life itself through genetic engineering, cyborg engineering, and the engineering of non-organic life. The question remains: What do we want to become?
Key Insights
- Imagined Orders: Our societies are built on shared myths (law, money, religion).
- Happiness: History shows little evidence that we are happier than our ancestors.
- Biology vs. History: Biology sets the parameters, but history defines the limits.
Sapiens challenges us to reconsider our accepted narratives and to think deeply about who we are and where we are going.
