[ABAD] Sapiens – Is It Too Long? Start With These 7 Big Ideas

Let’s be honest. You’ve probably heard of Sapiens by Yuval Noah Harari, maybe even bought it, but never quite made it past chapter two. You’re not alone.

At over 400 pages of history, biology, economics, and philosophy, Sapiens is a modern classic that feels more like a marathon than a book. But what if you could get the essence of it, not a summary but the core insights, in ten minutes?

Let’s do exactly that.
Below are seven powerful takeaways from Sapiens that help explain who we are, how we got here, and why our world is built the way it is. These points go beyond summaries. They are ideas you will actually think about after you close this tab.

And if the book ever felt too long or too dense, this is where to start.


1. Humans dominate the Earth not because we’re strong, but because we believe in fiction

Around 70,000 years ago, humans experienced what Harari calls the Cognitive Revolution. It wasn’t about walking upright or using fire. Other animals did that too. The real game-changer was the ability to imagine things that don’t exist, talk about them, and convince others to believe in them.

Think about gods, nations, human rights, companies, and money. None of these things exist in nature. Yet, we organize our entire lives around them.

This ability to create and share collective myths gave Homo sapiens an edge over every other species. We cooperate in large numbers not because we are kind, but because we believe in the same stories.

The real superpower of humans is storytelling. That is what makes mass cooperation and civilization possible.


2. The greatest leap in knowledge came when humans admitted they didn’t know everything

One of the most profound ideas in Sapiens is this.
The scientific revolution began with humility.

Up until the 1500s, most societies believed they already had all the answers. These answers were often found in holy books or ancient philosophy. When faced with something unknown, people assumed it either didn’t matter or was unknowable.

But then something changed. Scientists started saying, “We don’t know, but we want to find out.”

That small shift in mindset led to everything from Newton’s laws to space travel.
In fact, old world maps before the 16th century were completely filled in, even if parts were imaginary. Later maps began leaving blank spaces. This was an honest admission of ignorance, which sparked exploration, curiosity, and massive technological progress.

Acknowledging that we don’t know something is not a weakness. It is the beginning of real knowledge.


3. Humans didn’t become rulers of the planet by being virtuous. We disrupted the ecosystem

Why are humans at the top of the food chain? Not because we were morally superior or stronger.
We simply moved too fast.

Harari points out that when predators like lions or sharks rose to the top, it took millions of years. This gave the ecosystem time to adapt. But humans rose in just a few thousand years, which is almost overnight in evolutionary terms.

Other animals had no time to adjust.
This led to mass extinctions and ecological damage. For example, many large mammals disappeared shortly after humans reached Australia and the Americas.

Our domination is not natural. It is disruptive. We are not the top because we fit in, but because we changed the rules too quickly.


4. Human progress does not equal human happiness

This one hits hard.
Yes, we have cities, smartphones, and life-saving medicine. But are we really happier than ancient foragers who roamed the land freely, ate a diverse diet, and worked fewer hours?

Harari argues that the Agricultural Revolution, which we usually celebrate, was a mixed blessing.
It allowed population growth, but also introduced hard labor, poor diets, inequality, and disease. People settled down to grow wheat, but wheat ended up domesticating us.

The species succeeded, but the individuals may have suffered.

This idea leads to a haunting insight.
More people, more tools, more power, but not necessarily more joy.


5. Civilizations grow when people believe in the same imaginary rules

Humans didn’t build pyramids, nations, and corporations just because of tools or intelligence. We built them because we believe in shared fictions.

These shared beliefs are what Harari calls imagined orders, such as money, religion, and law. They aren’t real in the way gravity or atoms are. But they are powerful because we act as if they are real.

A dollar bill only has value because millions of people agree that it does.

Even things we cherish, such as human rights or democracy, are ideas we’ve created, believed in, and institutionalized. They are not biological facts. They are collective beliefs that structure our world.

If enough people believe in the same story, it becomes the reality we live in.


6. Capitalism works because people believe tomorrow will be better

Why would someone lend money or take out a loan to start a business? It only works if both sides believe in a common story. That story is that the future will be bigger, richer, and better.

That is the core of capitalism. It is not just about money.
It is about trust in future growth. Harari explains that modern economies are built not just on hard currency, but on credit. Credit only exists when there is belief in future returns.

This belief has driven explosive progress, but it also led to things like colonialism, slavery, and climate change. Capitalism is powerful, but not always moral.

Capitalism depends on the story that growth is endless. But what happens when that story stops making sense?


7. We live inside systems we’ve created, but we forget they’re invented

Today, we take certain values for granted.
Freedom, equality, patriotism, success. But none of these are universal truths. They are ideas we have invented, accepted, and passed down.

The most dangerous myths are the ones we forget are myths.

From ancient religions to modern nationalism, humans are storytelling animals. That is both our strength and our weakness. We can unite by the billions or divide just as easily.

History is not just what happened. It is the stories we chose to believe about what happened.


So… What’s the real message?

Let’s go back to a question many readers ask.

If civilization has advanced so much, why doesn’t it always feel better?

That is the key idea Harari wants us to wrestle with.
We have conquered nature, built empires, and explored galaxies, but still struggle with loneliness, burnout, and meaning.

Progress is not always personal.
The human species may be thriving, but the individual human is not always doing better.

That is not to say things were better in the past. But Sapiens makes us question the automatic assumption that more is always better, and that newer is always wiser.


If the book felt overwhelming, just remember this:

  • We rule the Earth because we tell stories
  • Those stories only work if people believe them
  • Belief, not truth, is the foundation of civilization

And if you never finish Sapiens, that’s okay.
Knowing these seven ideas might be even more powerful than reading all 400 pages.


Too long, too complex, too late to start reading the whole book? No problem. You just did.

[ABAD] Guns, Germs, and Steel – Why Guns, Germs, and Steel Still Matters — And What Most People Miss by Stopping at Page 10

“Why do white people have so much cargo?”
Yali, a New Guinean politician

This was the question that changed everything for scientist Jared Diamond. A local politician in Papua New Guinea asked him why some countries seem so rich and powerful while others are not.

Diamond could not stop thinking about it. That one question became a global best-seller, a Pulitzer Prize-winning book, and a completely new way of understanding human history. That book is Guns, Germs and Steel.

Many people start reading it and give up after a few pages. It feels like a textbook. But behind the complex language is a simple and powerful idea:

The real cause of inequality in the world is geographic luck, not intelligence, culture or race.

Let’s break it down in a way that anyone can understand. In this article, we will walk through the seven key ideas in Guns, Germs and Steel. These ideas explain why some civilizations grew rich and powerful while others struggled to survive.


1. It’s Not About Race. It’s About Environment.

One of the most dangerous and outdated beliefs in history is that people in rich countries are more intelligent or more hardworking than others.

Diamond completely rejects this idea.

He says that Europe and Asia developed faster not because of better people, but because they had better starting conditions after the last Ice Age.

Some areas had the right kinds of wild plants and animals to support farming. Others did not.

Some continents had flat land, easy travel routes and mild climates. Others were filled with deserts, jungles and extreme weather.

Over thousands of years, these small differences led to huge inequalities in technology, health, population and power.


2. Farming Was the First Big Step

Before farming, humans lived by hunting and gathering. But farming changed everything.

People could now grow their own food, store it, and stay in one place. This led to:

  • Bigger populations
  • Permanent villages and cities
  • Special jobs (like leaders, soldiers and builders)
  • Inventions like writing, math and government

But here’s the key point. Farming was not possible everywhere.

The earliest crops like wheat, barley and rice only grew wild in certain parts of the world. These plants could be domesticated, meaning humans could plant and harvest them easily.

Places like the Middle East, China and Central America had good luck. Other places, like Australia or southern Africa, did not.

So even if people were equally smart, they did not have the same tools to build civilizations.


3. Animals Made a Huge Difference

Farming plants was important, but domestic animals were even more powerful.

Animals like cows, sheep, pigs and horses helped with:

  • Plowing fields (which increased food)
  • Providing milk, meat and hides
  • Carrying goods long distances
  • Helping in war (especially horses)

But again, only a few parts of the world had animals that could be tamed.

There are very strict requirements for domestication. The animal must:

  • Eat plants (not meat)
  • Grow quickly
  • Be friendly and calm
  • Live in groups
  • Be okay with being controlled by humans

Zebras, elephants and kangaroos do not qualify. Horses, cows and goats do.

And guess what? Most of the animals that humans could tame were found in Eurasia, not in the Americas or Africa.

This gave some societies a huge head start.


4. East-West Shaped Civilization. North-South Did Not.

Another big idea in the book is about the shape of continents.

Eurasia (Europe and Asia together) stretches east to west. The Americas and Africa stretch north to south.

That matters because plants, animals and technologies spread more easily across areas with similar climates.

If you move east or west, the climate stays about the same. But if you move north or south, the temperature, rainfall and seasons change a lot.

For example, if a new crop is developed in China, it can spread west into the Middle East and then into Europe.

But a new crop from Mexico would have a hard time reaching Peru. It would have to pass through deserts, jungles, mountains and tropical zones.

That is one reason why technology spread so fast in Eurasia but stayed isolated in the Americas and Africa.


5. Germs Were the Most Deadly Weapon

When Europeans arrived in the Americas, they had steel swords and guns. But their most powerful weapon was something invisible germs.

Diseases like smallpox, measles and flu killed up to 90 percent of Native Americans. In many cases, entire tribes were wiped out before a single shot was fired.

Why was this so deadly?

Because people in the Americas had never lived with large animals. That means they had not been exposed to the kinds of diseases that came from livestock.

Europeans, on the other hand, had spent centuries living with cows, pigs and chickens. Over time, their bodies developed resistance to many deadly germs.

The germs themselves evolved too. So when Europeans arrived, they brought diseases that spread fast and killed millions, often without even realizing it.


6. Inventions Don’t Change the World Until Society Is Ready

Many people believe that when we need something, we invent it.

Diamond flips that idea around.

He says invention creates need, not the other way around.

For example:

  • Thomas Edison invented the phonograph to record office meetings, not for music.
  • Gasoline was once thrown away as useless waste during oil processing.
  • The QWERTY keyboard was designed to slow down typists. Yet we still use it today.

The point is this. A great invention does not guarantee success. What matters is whether society is willing and able to adopt it.

Some technologies are ignored or forgotten because the culture, economy or politics are not ready for them.


7. Writing Systems Changed Everything

Writing is one of the most important inventions in history. It allows humans to:

  • Record laws and taxes
  • Share stories and ideas
  • Organize large societies
  • Educate future generations

But surprisingly, only three civilizations created writing from scratch:

  • The Sumerians in the Middle East
  • The Chinese
  • The Maya in Central America

All other writing systems were borrowed or inspired by these three.

For example:

  • The Roman alphabet (which we use today) was based on older alphabets like Phoenician.
  • Korean Hangul is a unique case. It was inspired by the idea of writing, but built from new principles. Diamond calls Hangul a linguistic miracle.

He also praises Hangul for being simple, logical and easy to learn, especially for beginners.


Bonus: What About Famous Leaders Like Hitler or Columbus?

You might wonder, what about leaders like Hitler or Columbus? Didn’t they shape history?

Diamond agrees that individual people matter, but only to a point.

If Hitler had died early, maybe someone else would have taken his place. The forces of history, such as resources, technology, and political systems, would still exist.

This is why Diamond focuses on geography and systems, not just famous names.


Final Message: Geography Set the Stage. We Just Played the Roles.

Jared Diamond’s main argument can be summarized in one simple sentence:

The world is unequal not because of better people, but because of better geography.

No civilization is naturally superior. No race is born to conquer others.

The real difference comes from climate, crops, animals, and whether ideas can move easily across the land.

It may not feel exciting. It’s not the story of genius kings or dramatic battles. But it is the truth behind 13,000 years of human history.


What You Can Do Next

If you have a copy of Guns, Germs and Steel on your shelf, maybe it’s time to pick it up again.

Start with this question:

Why does the world look the way it does today?

And then read with curiosity, not guilt. You don’t have to agree with everything Diamond says. But his ideas will make you think deeper about history, fairness, and the future.


Bonus Recommendation: Watch The Revenant

Want to see some of these ideas in action?

Watch The Revenant (2015) starring Leonardo DiCaprio. It’s not just about a bear attack. The film also shows the tension between Native Americans and Europeans — including the invisible violence of disease and cultural destruction.
