About the Author

Yuval Noah Harari is an Israeli historian and professor in the Department of History at the Hebrew University of Jerusalem. He writes about free will, consciousness, intelligence, and happiness. He focuses on the “cognitive revolution” that occurred 70,000 years ago when Homo sapiens replaced the Neanderthals and developed language skills and structured societies, moving upward as apex predators. The agricultural revolution and scientific method assisted this transition. He also focuses on the consequences of a possible biotechnological world in the future in which intelligent creations are surpassed by their own creations. He believes that Homo sapiens as we know it will disappear in a century or so.

He was born in Israel and grew up in a secular Jewish family,. He practices Vipassana meditation, which he said changed his life. He has published numerous books and articles and now focuses on world history and macro historical processes.

His book, Sapiens is based on 20 lectures of an undergraduate world history class he was teaching. The book was a success and was translated into 45 languages. It looks at human history, from the evolution of Homo sapiens in the Stone Age to the political and technological revolutions of the 21st century.

Key Insights

Through the study of physics, we have learned the story of the Big Bang, which occurred about 13.5 billion years ago in the skies.

And within the last 70,000 years, Homo sapiens appeared. Since their appearance, humankind has gone through three dynamic revolutions:

The Cognitive Revolution

The Agricultural Revolution

The Scientific Revolution

“Culture tends to argue that it forbids only that which is unnatural. But from a biological perspective, nothing is unnatural. Whatever is possible is by definition also natural. A truly unnatural behavior, one that goes against the laws of nature, simply cannot exist, so it would need no prohibition.”

― Yuval Noah Harari

Currently, we are in the scientific revolution which started about five centuries ago. It is progressing at rapid speeds, but we are still unsure of the final outcome.

The Cognitive Revolution

We, as a species, are not the only humans to have walked the face of the earth. All of our ancestors were the genus Homo. Homo sapiens, however, appeared and disrupted the natural order by bringing in advances of language, cognition or thinking, and technology.

Now, we are currently at another turning point in humankind with our own existence, as humans are being rivaled by the introduction of artificial intelligence.

For over two million years, we lived with our thinking processes and capacity for learning without advantages to match. Homo sapiens were for a long time in the middle of the food chain. Now, we are at the top so our advantages now match our intellect.

For thousands and thousands of years, Neanderthals were superior to Sapiens. When Sapiens first encountered Neanderthals in the Middle East, they were quickly overpowered and the Sapiens fled back to Africa, where they came from.

But 70,000 years passed, and Sapiens once again decided to leave the comfort of Africa. On their way to Asia and Europe and even Australia, they overpowered Neanderthals.

The Cognitive Revolution is documented through the appearances of sewing needles, boats, oil lamps, and art throughout history. But, the greatest development that resulted from the Cognitive Revolution, was language.

Language helped to communicate danger to other beings and it also helped to keep information stored safely in the brain.

For example, an animal can warn its species that there is an enemy approaching. However, only a human can warn their tribe of the possibility of danger based on an enemy’s signs, such as footprints or tree rubs. Humans can store the information they have seen and present it to their tribe later, whereas animals can only warn against immediate danger in the present to the animals around them.

“You could never convince a monkey to give you a banana by promising him limitless bananas after death in monkey heaven.”

― Yuval Noah Harari

The Cognitive Revolution and language also brought humankind the gifts of spirituality, religion, and the supernatural. Or in other words, it gave us the ability to understand and think about things we cannot see or touch.

But, with more intellectual thinking came war, hierarchies, and politics.

By understanding our hunting-and-gathering ancestors, we are better able to understand ourselves....
