What Makes a City Excellent? Al-Farabi’s Big Idea About Society, Happiness, and Religion

Imagine you’re designing a city from scratch. Not just the buildings and roads—the whole thing: how people live, what they believe, who’s in charge, and what everyone is trying to achieve together. What would be the point of your city? What would make it a good one?

A philosopher named al-Farabi asked this question in the 10th century, living in what is now Iraq. His answer was strange, ambitious, and still worth thinking about. He said that a truly excellent city—what he called the “virtuous city”—has to aim at one thing above all else: helping every single person in it reach true happiness.

But here’s where it gets interesting. Al-Farabi didn’t think happiness meant having fun, or getting rich, or even being healthy. For him, happiness meant something much weirder: becoming so good at thinking that your soul survives death and joins a kind of cosmic mind. And he believed that most people couldn’t get there on their own—they needed society to help them. That’s where religion came in, but not in the way you might expect.

What Do We Need Each Other For?

Al-Farabi started with a simple observation: humans can’t survive alone. We need other people to grow food, build shelter, teach us things, and protect us. But he went further. He said we don’t just need each other to survive—we need each other to become fully human. Without society, he wrote, “man cannot attain the perfection for the sake of which his inborn nature has been given to him.”

What is this “perfection”? For al-Farabi, it’s about your intellect—the part of you that can think, reason, and understand abstract truths. He believed that every human being has the potential to become a perfect thinker, but that potential has to be developed. You’re born with the ability to learn, but you have to actually do the learning. And you can’t do that alone.

So a society, on his view, isn’t just a collection of people who happen to live near each other. It’s a cooperative project aimed at helping everyone reach their highest potential. The smallest unit that can actually do this properly, he thought, is a city. Villages are too small; they can’t provide everything people need. But a well-organized city—if it’s the right kind—can.

The Happiness That’s Hard to Describe

Now we need to talk about what al-Farabi meant by “happiness,” because it’s not what you probably think.

He believed the universe is layered. There’s the physical world we can see and touch—plants, animals, rocks, our own bodies. But above that, there’s a realm of pure, immaterial minds: beings that do nothing but think. The highest of these is something he called the “Active Intellect.” It’s like a cosmic thinking-machine that never stops.

Here’s the key: humans are weirdly positioned between these two worlds. We have bodies (physical) and minds (capable of thinking). Our job in life—our natural purpose—is to use our minds to understand reality as deeply as possible. The more we understand, the more our minds become like the Active Intellect. If we succeed, al-Farabi said, our souls become so pure and powerful that when our bodies die, our souls survive and join the cosmic thinking. That’s what he meant by true happiness: becoming an actual, thinking mind that exists forever.

But if we fail—if we spend our lives chasing food, status, pleasure, or money instead of understanding reality—our souls don’t develop properly. They might not survive death at all. Or they might survive in a weaker, less happy state.

This is a pretty heavy idea. Al-Farabi himself wasn’t completely sure whether you could reach this happiness during your lifetime or only after death. But he was clear that it’s the whole point of being human. And that means society has a massive responsibility.

The City as a Giant Body

How should we organize a city to help everyone reach this strange form of happiness? Al-Farabi thought the best model was right in front of us: the human body.

Think about how a healthy body works. Your heart pumps blood. Your lungs take in air. Your stomach digests food. Each organ has its own job, and they all cooperate to keep the whole body alive. No organ tries to do another organ’s job. The heart rules (it’s the most important), but it doesn’t do everything.

Al-Farabi said the excellent city should work the same way. People are born with different natural talents and abilities. Some are naturally smart and can become philosophers. Others are good at building, farming, teaching, or leading. Each person has a natural place and a natural job. The city flourishes when everyone does their own job well and cooperates with everyone else.

The ruler of the city should be like the heart: the most important part. And who should rule? The person who understands reality best—the philosopher. Al-Farabi believed that only someone who truly understands the universe, human nature, and what happiness really is can guide a city correctly.

But here’s a problem he noticed: not everyone can become a philosopher. Most people, he thought, don’t have the natural intelligence to grasp the deepest truths about reality. They can understand some things, but not everything. So how can they still reach happiness?

Two Ways of Knowing

Al-Farabi’s solution was clever. He said there are two ways to know the same truth.

The first way is through demonstration—using logic and evidence to prove something beyond doubt. This is what philosophers do. They understand things as they really are. For example, a philosopher might understand that the universe was created by a first cause that is pure thought.

The second way is through symbols and stories—using images, metaphors, and examples that capture the truth without explaining it technically. This is what most people can understand. Instead of “the first cause is pure thought,” you might say “God created the heavens and the earth and knows everything.”

These are both about the same reality. One is a precise map; the other is a vivid painting. Both point to the same place. Al-Farabi called the second way “symbolic representation.”

This is where religion enters his picture.

Religion as a Tool

Al-Farabi defined religion in a way that might surprise you. He said religion is a set of opinions and actions that a ruler prescribes for a community, aiming to help people reach happiness. It’s not something that comes directly from God. Instead, it’s something a wise ruler creates—or at least interprets—to guide people who can’t understand philosophy directly.

In other words, for al-Farabi, religion is philosophy translated into symbols. The prophet or founder of a religion is actually a philosopher who also has the special ability to turn difficult truths into stories, images, and laws that everyone can follow. The Qur’an, for example, would be a symbolic version of philosophical truth, designed for people who need pictures before they can grasp ideas.

The practical rules of religion—prayer, fasting, charity—serve a purpose too. They train people’s character, helping them develop good habits and purify their souls so they’re ready for the real work of thinking. It’s like practicing scales on an instrument before you can play complex pieces.

This doesn’t mean religion is false. It’s just a different level of understanding. Philosophy is higher—it sees things clearly. Religion is lower but still true, just in a different way. And crucially, the philosopher-ruler needs both: philosophy to understand reality, and religion to guide the city.

What Makes a City Fail?

Al-Farabi also described cities that fail. These are societies that aim at the wrong things.

Some cities aim only at survival—getting enough food and shelter. That’s fine as a start, but if that’s all they do, they’re missing the point. Other cities aim at wealth, pleasure, power, or honor. Al-Farabi called these “ignorant” cities. Their citizens chase what seems good but isn’t really good. They might be comfortable, even happy in a shallow way, but they won’t reach true happiness.

Worst of all are “immoral” cities, where people know what’s right but do the opposite anyway. They understand that they should pursue truth and virtue, but they choose pleasure or status instead. Al-Farabi said no one in these cities gains true happiness.

This might sound harsh. But notice what he’s saying: a society can be well-organized, peaceful, and prosperous, and still be failing at its real purpose. The test isn’t whether people are comfortable. It’s whether they’re being helped to become fully human.

Living Questions

You might notice some tensions in al-Farabi’s ideas. They’re worth sitting with.

First, is it fair that some people are naturally smarter than others? Al-Farabi thought this was just a fact of nature, like some people being taller. But if happiness depends on understanding reality, and most people can’t understand it directly, is everyone really getting an equal chance? He said yes—because symbols and religion can give people the same essential truth in a form they can grasp. But does that really work? Or are second-hand beliefs less reliable?

Second, think about authority. The philosopher-ruler knows what’s true and guides everyone else. But what if the ruler is wrong? What if someone claims to be a philosopher but isn’t? Al-Farabi didn’t have a great answer to this. He hoped that the natural order of things would make the wisest people obvious.

Third, is al-Farabi’s view of religion respectful? He basically said religion is a simplified version of philosophy, useful for people who can’t handle the real thing. Many religious people would disagree—they think their faith contains truths that philosophy can’t reach. Al-Farabi would say that’s impossible, because there’s only one reality and reason can understand it. But that’s a big claim.

Why This Still Matters

Al-Farabi was writing a thousand years ago, but his questions are still ours. What should a society aim for? Is the point just to keep people fed and safe, or is there a higher purpose? How should we handle the fact that people have different abilities? And what’s the relationship between rational understanding and religious faith?

These aren’t just academic questions. Every time a school decides what to teach, a government decides how to spend money, or a community argues about its values, al-Farabi’s questions come back. What does it mean to live well together? And what does it mean for each of us to live a good life?

He didn’t have the last word, and he knew it. But he gave us a framework that’s worth wrestling with—even if you disagree with him.

Key People

Al-Farabi (c. 870–950 CE): A philosopher who lived in Baghdad (modern Iraq) and tried to combine Greek philosophy (especially Plato and Aristotle) with Islamic thought. He wrote about politics, religion, music, and logic, and was called the “Second Teacher” (after Aristotle).
Aristotle: An ancient Greek philosopher (384–322 BCE) who wrote about ethics, politics, logic, and science. Al-Farabi borrowed heavily from his idea that humans have a natural purpose.
Plato: An ancient Greek philosopher (c. 428–348 BCE) who wrote The Republic, a book about the ideal city ruled by philosopher-kings. Al-Farabi adapted many of Plato’s ideas about who should rule.

Things to Think About

Al-Farabi thought the ruler of an excellent city must be a philosopher who understands reality. But what if the wisest person doesn’t want to rule? What if they’d rather just think? Should they be forced to lead?
If religion is a simplified version of philosophy, does that mean religious people are being deceived—even if it’s for their own good? Or is there a difference between being deceived and being taught through symbols?
Al-Farabi said people have different natural abilities. But how much of what we can do comes from nature, and how much from training, education, and opportunity? If society arranged things differently, would more people be capable of philosophy?
Is happiness really about understanding reality? Or could someone be truly happy without ever thinking about deep questions? What would al-Farabi say about someone who is perfectly content living a simple life?

Where This Shows Up

Debates about school curriculum: Should schools focus on teaching students to think critically (like philosophy) or on practical skills and values (like a kind of “religion” for citizenship)?
Science and religion: Al-Farabi’s idea that religion and philosophy describe the same reality in different ways is still alive today—some people think science and religion are enemies, and others think they’re just different languages for the same truths.
Political leadership: People still argue about whether leaders need to be wise (like philosopher-kings) or just effective at managing things. Al-Farabi would say wisdom comes first.
Utopian fiction: Books and movies about perfect societies (utopias) often wrestle with al-Farabi’s questions: Who should rule? What’s the purpose of society? And what happens to people who don’t fit the plan?
