What Makes a Name Right? Language and Logic in Early Chinese Philosophy

The Puzzle

Imagine two people pointing at the same object. One says “That’s a horse.” The other says “No, that’s not a horse.” They can’t both be right—or can they? What makes one of them correct? Is it something about the animal itself? Something about the word “horse”? Something about who gets to decide?

For a group of ancient Chinese thinkers called the Mohists (moh-ists), these weren’t idle questions. They believed that getting names right was the key to getting everything else right—ethics, government, even how to live a good life. But other philosophers disagreed, and their arguments about language and logic still matter today.


Why Language Became So Important

In ancient China, around the 5th to 3rd centuries BCE, philosophers were fiercely debating how society should be organized. The most influential thinker, Confucius, had said something strange: the first thing he’d do if given power over a state was to “order names”—to make sure words were used correctly.

His student Zilu thought this sounded impractical. But Confucius explained it like this: when names aren’t used properly, language doesn’t work effectively. When language doesn’t work, nothing gets done properly. Rituals fall apart, punishments miss their mark, and people don’t know how to behave.

This wasn’t just about being precise. Confucius believed that words don’t just describe the world—they shape it. Calling someone a “king” isn’t just labeling them; it’s saying they ought to act like a king. If someone acts like a tyrant, maybe they don’t deserve to be called “king” at all. The name carries a demand for proper behavior.

But here’s where it gets tricky. Who decides what counts as proper behavior? Confucius pointed to tradition, ritual, and the judgment of wise people. The Mohists weren’t satisfied with that. They pointed out that traditions vary wildly across time and place—how could all of them be right? They wanted a more objective standard, based on reason and evidence that anyone could check.


The Mohist Project: Can We Get Names Right Through Reason?

The Mohists developed the most systematic philosophy of language in early China. They called their method bian (bee-en), which means something like “disputation” or “drawing distinctions.” For them, the basic job of language was to sort things into categories based on their similarities and differences.

Here’s how they thought it worked. To decide whether something is a horse, you compare it to a model—a standard example of a horse. If the thing resembles the model enough (in the right ways), you can call it a horse. The resemblance has to be “appropriate”: a horse’s bigness comes from its body, not its eyes, so you don’t call a horse “big” just because its eyes are big.

This might sound simple, but it gets complicated fast. The Mohists realized that objects can resemble each other in many ways, and what counts as “appropriate” depends on context. A white horse is like a brown horse in being a horse, but not in being white. So the same object can be correctly called “white” in one context and “horse” in another.

The Mohists identified three kinds of names:

  • Unrestricted names like “thing” that apply to everything
  • Classifying names like “horse” that apply to a group of similar things
  • Private names like “Jack” that apply to only one individual

Their big innovation was realizing that these different kinds of names work differently. And they noticed something even stranger: two names can refer to the same thing but function differently in combination with other words.

For example, “dog” and “canine” refer to the same animals. But knowing that dogs are canines doesn’t mean someone knows that canines are dogs—if they’ve only heard the word “canine” in a biology textbook. The Mohists saw that what happens inside a phrase like “knowing dogs” is different from what happens inside “knowing canines,” even though the words point to the same creatures.

This led them to discover what philosophers now call intensional contexts—situations where you can’t swap one word for another that means the same thing without changing the meaning of the whole sentence. This was a genuinely original discovery, probably made nowhere else in the ancient world.


When Grammar Tricks You

The Mohists became fascinated by how the same grammatical pattern could produce completely different meanings. Consider these two sentences:

  • White horses are horses; riding white horses is riding horses.
  • Robbers are people; killing robbers is killing people.

These look like they follow the same pattern. But the Mohists said the second one doesn’t work the same way. “Killing robbers” (they meant something like legal execution) wasn’t the same as “killing people” (murder). The meaning of the whole phrase wasn’t just the sum of its parts.

This wasn’t a trick. The Mohists were genuinely trying to understand how language works, and they found that it’s messier than we’d like. They developed four techniques for reasoning about language:

  1. Analogy: Using examples to clarify what something is
  2. Parallelizing: Comparing expressions that have similar grammatical form
  3. Pulling: Saying “You accept this, so why won’t you accept that?”
  4. Pushing: Using what someone already accepts to get them to accept something new

But they warned that all these methods can fail. “Things have respects in which they are similar, yet it doesn’t follow that they are completely similar,” they wrote. “Parallels between expressions are correct only up to a point.”

This is honest about difficulty. The Mohists were saying: we need to reason carefully about language, but we also need to be humble about what reasoning can accomplish.


The Daoist Challenge: Can Language Ever Capture Reality?

Enter Zhuangzi (jwong-zuh), a Daoist philosopher who read the Mohists and thought they were asking the wrong question. He didn’t deny that the world has real similarities and differences. But he argued that no matter how carefully we analyze language, we’ll never get a fixed, reliable guide for how to act.

Zhuangzi loved using examples of skilled craftspeople who couldn’t explain what they did. A wheelwright named Pian described his work: “You can get it in your hand and feel it in your mind. You can’t put it into words, and yet there is a knack to it somehow. I can’t teach it to my son and he can’t learn it from me.”

If a wheelwright can’t explain his skill, how can philosophers expect to capture the subtleties of ethical action in fixed definitions?

Zhuangzi also pointed to how words like “this” and “that” shift meaning depending on who’s speaking. If I point to an object and say “this,” you might point to the same object and call it “that.” There’s no fixed, perspective-free way to use these words. And if that’s true for simple pointing words, maybe it’s true for all language. Maybe every act of naming is tied to a particular perspective that can’t be universalized.

This is a radical challenge. The Mohists had hoped that careful analysis would reveal real patterns in the world that could guide everyone the same way. Zhuangzi suggested this was impossible—not because we’re stupid, but because language itself can’t do that job.


Xunzi’s Solution: Let Authority Decide

A later Confucian philosopher named Xunzi (shoon-zuh) took Zhuangzi’s challenge seriously but rejected his conclusion. Xunzi agreed that language couldn’t be grounded in objective similarities and differences alone. But instead of giving up on reliable language, he argued that the solution was convention backed by authority.

The names we use, Xunzi said, are ultimately arbitrary. There’s no reason why we couldn’t have called triangles and squares by the same name. What matters is that we agree on conventions, and that this agreement is enforced by wise rulers who know what’s good for society.

Xunzi was blunt about this. “Hair-splitting wordings and invention of names on your own authority, to disorder correct names and put people in doubt and confusion… are to be pronounced the worst of subversions, to be condemned like the crime of falsifying tallies and measures.”

This sounds harsh. But Xunzi had a reason for it. He believed human nature was fundamentally corrupt and couldn’t be trusted to figure out ethics on its own. Society needed clear rules imposed from above, and language was part of that system.

The Mohists had believed that ordinary people could use reason to determine right and wrong independently. Xunzi said no—that’s a job for educated elites who have spent years cultivating wisdom. The rest of us follow their lead.


Still Unresolved

So who was right? The Mohists, who believed careful reasoning about language could guide us to ethical truth? Zhuangzi, who thought language was ultimately too slippery for that job? Or Xunzi, who said we need authority to settle these questions?

Nobody really knows. These debates continue today, not just among philosophers who study ancient China, but among linguists, cognitive scientists, and anyone who wonders how words relate to the world. The Mohists discovered real phenomena about how language works—the way meaning changes in combination, the limits of compositionality, the existence of intensional contexts. But they may have been too optimistic about what language can achieve. Zhuangzi’s skepticism about fixed meanings may capture something important about human experience. But his approach offers little guidance for building a functional society. Xunzi solved the practical problem by deferring to authority, but at the cost of giving up on the idea that ordinary people can reason about ethics for themselves.

Perhaps the most honest conclusion is the one the Mohists themselves reached: language is powerful but imperfect, and we need to keep thinking about it carefully—without pretending we’ve found the final answer.

Key People

  • Confucius (551–479 BCE): The founder of a major philosophical tradition who insisted that getting names right is essential for a well-ordered society.
  • Mozi (c. 470–391 BCE): The founder of Mohism, who argued that ethics should be based on utility and universal love, not tradition.
  • The later Mohists (3rd century BCE): Anonymous followers of Mozi who developed sophisticated theories of language and logic found in the Mohist Canons.
  • Zhuangzi (4th century BCE): A Daoist philosopher who argued that language can never capture reality in a fixed way, because meaning always depends on perspective.
  • Xunzi (c. 310–235 BCE): A Confucian philosopher who argued that language works by convention, not by capturing real patterns, and that authority must enforce correct usage.

Things to Think About

  1. If you accept Xunzi’s view that language is ultimately arbitrary and needs authority to enforce it, who gets to be that authority? How would you decide who’s wise enough to decide how words should be used?

  2. Zhuangzi seems to suggest that some kinds of knowledge can’t be put into words at all. Can you think of something you know how to do that you couldn’t explain to someone else? Does that mean language has limits? Or does it mean you just haven’t found the right words yet?

  3. The Mohists thought careful reasoning could determine ethical truth. But they also admitted that the same grammatical pattern can produce different meanings. If we can’t trust grammar to guide us, what can we trust? Is there a way to be both careful and humble about what language can do?

  4. Confucius believed that calling someone a “king” meant they ought to act like a king. Do we still use words this way today? Think about titles like “friend,” “leader,” or “expert”—do these words describe something about a person, or do they also demand certain behavior from them?

Where This Shows Up

  • Everyday arguments about definitions: When people argue about whether a video game counts as “art” or whether a particular action counts as “stealing,” they’re having the same kind of debate the ancient Chinese philosophers had about what makes a name correct.
  • Legal disputes: Courts constantly argue about whether a specific action falls under a general law—is downloading music “theft”? Is a hoverboard a “vehicle”? These are questions about how names apply to things.
  • Social media and “calling out”: When people argue about who deserves to be called what (racist, hero, friend), they’re engaging in the ancient practice of zheng ming—deciding that names carry moral weight and shape how we should act.
  • Artificial intelligence: When we try to teach computers to understand language, we run into exactly the problems the Mohists discovered: the same grammatical pattern can mean different things, context matters enormously, and meaning isn’t always compositional.
