《公孫龍子》

Gongsun Long was a renowned logician from the State of Zhao during the Warring States period. Distressed by the prevailing confusion between names and realities in society, he employed his intellectual talents to establish the "Theory of Guarding Whiteness" (a doctrine insisting on the essential nature of things). Through metaphorical arguments using concrete objects, he developed his most famous proposition: "A white horse is not a horse."

His argument proceeded thus: When we say "white," we refer to color; when we say "horse," we refer to form. Color is not equivalent to form, nor is form equivalent to color. Combining "white" and "horse" into the compound term "white horse" creates something distinct from "horse" alone. Consider searching for a white horse in a stable—if only black horses are present, one cannot claim a white horse exists. Since we cannot acknowledge the existence of a white horse under these circumstances, the "horse" being sought does not exist, thereby proving that a white horse is indeed not a horse. Gongsun Long sought to rectify the relationship between names and realities through such dialectics, aiming to enlighten society.

Later, when Kong Chuan encountered Gongsun Long at Lord Pingyuan's residence, he expressed admiration for the logician's learning and wished to become his disciple—but only if Gongsun abandoned the "white horse" theory. Gongsun countered: "My reputation rests precisely on this theory of white horses. If I discard it, I'll have nothing left to teach. Moreover, becoming a disciple presupposes one's learning is inferior to the teacher's—yet you demand the teacher alters his views before accepting instruction. This violates proper principle." He further noted that even Confucius (Zhongni) had acknowledged similar propositions.

This passage recounts the debate between Gongsun Long (a representative figure of the School of Names during the Warring States period) and Kong Chuan (a descendant of Confucius) regarding the proposition "a white horse is not a horse." Through the story of the King of Chu losing his bow, it explores the discussion of the "relationship between names and reality."

When the King of Chu lost his prized bow named "Fanruo" and his sharp arrow "Wang Gui" while hunting in Yunmeng Marsh, his attendants wanted to search for them. The king said, "There's no need. If a man of Chu loses his bow, it will be picked up by another man of Chu. Why bother looking?" Confucius, upon hearing this, remarked: "Though the King of Chu shows benevolence, his perspective is still limited. He should have said, 'When a person loses a bow, another person will find it.' Why confine it to the people of Chu?"

Gongsun Long used this story to illustrate his point: the King of Chu's understanding of "person" was restricted to the people of Chu, whereas Confucius' understanding encompassed all people under heaven. This aligns with Gongsun Long's famous "white horse is not a horse" argument (which asserts that the concept of "white horse" is not equivalent to the broader category of "horse"). On the surface, it appears to be a distinction between concepts, but its essence lies in breaking through narrow perceptions.

Kong Chuan wished to become Gongsun Long's disciple but demanded that he abandon his "white horse is not a horse" theory. Gongsun Long retorted: "The core of my doctrine is precisely this proposition. If I discard it, I'll have nothing left to teach you. You seek to learn from me precisely because your wisdom and knowledge fall short. Yet now you demand that I first abandon my foundational teaching—this is unreasonable."

The passage concludes by noting that while different schools of thought may follow different paths, their ultimate goals are the same. If one clings stubbornly to their own views and fails to integrate diverse perspectives, they will remain entrenched in familiar ideas while disparaging unfamiliar ones. In such a case, even a hundred sages like Gongsun Long would be unable to guide one's progress. Just as insisting on the "white horse" standard might cause one to miss many fine horses, fixating on the perspective of Chu makes it difficult to benefit all under heaven.

This dialogue between Yin Wen and the King of Qi debates the criteria for defining a "true scholar" (士), exposing the inherent contradictions in a ruler's standards for selecting talent.

Yin Wen first asks the King to define his ideal scholar. The King lists four virtues: loyalty to the sovereign, filial piety, trustworthiness, and conformity to local customs. But when Yin Wen presents a hypothetical case where such a virtuous man fails to fight back when humiliated, the King immediately retracts his approval, declaring he wouldn't employ such a passive person. Yin Wen then points out the contradiction: how can the same person embody your four approved virtues yet be rejected for not fighting? Does your original definition of a scholar still hold? The King is left speechless.

Yin Wen then draws a political analogy: if a ruler indiscriminately metes out rewards and punishments—penalizing those who deserve praise and rewarding those who merit punishment—the people would naturally protest. The King agrees this would be poor governance. Yin Wen then delivers his critique: this is precisely how Qi's officials currently govern. With laws mandating execution for murder and punishment for assault, your people dare not resist oppression—they're simply obeying your decrees.

Employing the same logical reasoning as the famous "white horse is not horse" paradox (a signature dialectical method of the Gongsun Long school), the dialogue reveals how rulers often establish mutually exclusive standards: demanding strict legal compliance while simultaneously expecting unyielding courage. Through reductio ad absurdum, Yin Wen demonstrates how the King's expectations for scholars directly conflict with his own governance policies.

This passage is from Gongsun Longzi, primarily discussing the famous proposition "A white horse is not a horse" and related contradictions in reward-punishment judgments.

First addressing the paradox of rewards and punishments: If a ruler considers it shameful to endure humiliation without resistance, then those who do not resist should be punished. Yet these individuals have committed no crime and still face punishment, while those who dare to resist are rewarded. This creates confusion in the standards of justice—what the ruler commends may be what the law condemns; what superiors deem right, the law may deem wrong. When rewards, punishments, and judgments are completely inverted, not even ten Yellow Emperors (legendary sage rulers) could untangle such chaos.

The discussion then focuses on the "white horse is not a horse" proposition:

The term "horse" refers to the animal's physical form, while "white" denotes color. When we say "white horse," we emphasize its chromatic attribute rather than the general form of all horses—hence "a white horse is not an ordinary horse." It's like searching for horses by specific color: you'll only find that particular hue, which cannot represent the entire category. Although a white horse is indeed a type of horse, the phrase "white horse" highlights its distinctive white characteristic that differentiates it from generic horses.

This debate essentially explores the relationship between names (concepts) and substance: When we designate things by specific attributes (e.g., "white horse"), we're already making distinctions that cannot be simplistically equated with broader categories ("horse"). Just as when someone requests "bring the white horse," you wouldn't fetch a black one—demonstrating how daily usage implicitly acknowledges "white horse" as a particular kind of horse.

This passage discusses the famous proposition "A white horse is not a horse." Gongsun Longzi employs logical reasoning to demonstrate that when we speak of seeking a "horse," both yellow and black horses qualify; but when specifying a "white horse," yellow or black horses no longer meet the criteria. This shows that "white" and "horse" are distinct conceptual categories.

Just as a ruler's favor toward a particular individual doesn't prove that person more virtuous than others, human loyalty never permanently belongs to one sovereign—much like horses don't exist in only one color. If a ruler exclusively favors close associates while alienating others, those excluded will inevitably reciprocate with betrayal.

While yellow and black horses are indeed horses, they cannot be counted as white horses, proving that "white horse" and "horse" represent different conceptual categories. If one claims "a colored horse isn't a horse," then since no colorless horses exist in the world, would that mean horses don't exist at all? This parallels how all human relationships involve degrees of closeness, yet we cannot thereby deny humanity's existence.

Horses inherently possess color—hence white horses exist. If horses were colorless, simply saying "there are horses" would suffice; why specify "white horse"? Therefore, the attribute "white" doesn't belong to the essential nature of "horse." This argument reveals conceptual distinctions, demonstrating that compound concepts (white horse) cannot be simplistically equated with singular concepts (horse).

Gongsun Longzi discusses the famous proposition "a white horse is not a horse." He begins by pointing out: If we claim that only the general concept of "horse" exists, then why do we need to distinguish white horses? Just as humanity is necessarily divided into Hua (Chinese) and Yi (barbarians) due to racial differences, if there were no inherent clan distinctions in the world, how could there be differences between intimacy and estrangement? Whiteness is whiteness itself—it is not the horse.

He then analyzes: A white horse comprises two elements—"horse" and "white." When these two distinct things are combined into one, we cannot simply call it a horse. If we use the horse to represent whiteness, then a white horse cannot be equated with an ordinary horse. When a horse is not combined with whiteness, it remains an ordinary horse; when whiteness is not combined with a horse, it remains pure whiteness. To combine horse and whiteness and call it "white horse" is to forcibly join two unrelated concepts under one name. Therefore, the claim that "a white horse is not a horse" does not hold.

Next, he employs rhetorical questioning to argue: If having a white horse means having a horse, then can having a white horse be equated with having a yellow horse? Clearly not. If we acknowledge that a white horse belongs to the category of horses, yet a yellow horse cannot be equated with a white horse, then we are effectively saying that a yellow horse does not belong to the category of horses. This reasoning—excluding yellow horses from the category of horses while including white horses—is as absurd as making birds enter water or separating a coffin from its lid. Here, color (yellow or white) is forcibly used to define the form of a horse, creating logical confusion.

(Note: Gongsun Longzi was a representative figure of the School of Names, known for his expertise in logical reasoning. Through the proposition "a white horse is not a horse," he explores the relationship between the intension and extension of concepts, as well as universals and particulars, demonstrating the depth of ancient Chinese philosophical thought on logical problems.)

This passage discusses Gongsun Long's famous proposition that "a white horse is not a horse," using metaphorical language to explore philosophical reflections on the relationship between names and reality.

The relationship between an inner coffin and outer burial case is like that of lips and teeth—they depend on each other, for when the lips are gone, the teeth feel the cold. They cannot be stored separately. The border tribes guard the frontiers, while the central states maintain internal order; only when inner and outer rely on each other can the world be at peace. If one favors the central states while alienating the outer tribes, the tribes will rebel; if one exhausts armies in distant campaigns to oppress border peoples, the central lands will fall into turmoil. When inner and outer become estranged, it is like separating the inner coffin from the outer case—a ruler who shows partiality cannot govern alone. Thus, abandoning a yellow horse in favor of a white one is a great disorder.

Some say, "Having a white horse does not mean having no horse," but this is a perspective that separates whiteness from the horse. According to this view of separation, having a white horse does not mean having a horse. The reason we say "there is a horse" is simply because we take the horse as a horse, not because it is white that we consider it a horse. Therefore, one cannot say "horse-horse" (repeating the term to emphasize the essence of horseness).

Whiteness is not fixed to any particular object—it can be disregarded (since all things possess whiteness). Since whiteness does not exclusively belong to horses, and horses are not exclusively white, if we disregard color to seek the horse, all horses will fit; if we abandon personal bias to draw close to others, all people under heaven can be drawn close. The term "white horse" fixes whiteness to the horse, but this fixed whiteness is no longer whiteness itself (for the whiteness of a horse is only the whiteness of a horse—how can it represent whiteness itself?). The concept of "horse" does not involve selecting or rejecting colors—thus, both yellow and black horses can fit (when speaking simply of "horse," no color is selected, so all horses fit; since no color is excluded, all colors remain present. Therefore, the sage remains detached and forgetful, governing the myriad things through emptiness and stillness, and thus can embrace all things and exhaust all principles). But "white horse" involves color selection—yellow and black horses are excluded due to their colors, and only the white horse fits (excluding yellow and choosing white, the horses are distinguished by color, and only the white horse fits. The way of rulership is likewise).

This passage originates from Gongsun Longzi, primarily discussing the philosophical thought behind the famous proposition "a white horse is not a horse." Through metaphor, the author illustrates that if a ruler favors only those close to them while alienating the broader populace, the people will grow distant and even rebel. When all turn away, who will heed the ruler's commands? Likely only those favored insiders. Yet relying solely on such insiders to enforce orders not only fails to quell unrest but exacerbates chaos.

The text employs the logic of "a white horse is not a horse" to clarify: not selecting whiteness (symbolizing impartiality) does not mean eliminating yellowness (symbolizing total exclusion); not fixating on color distinctions (symbolizing personal biases) reflects that color and horse are inseparable as a whole. Just as yellowness and whiteness coexist in horses, closeness and distance naturally exist in human relationships. If one favors only the close while alienating others, the alienated will revolt; once they rebel, even the favored cannot survive alone.

Thus, the sage (one who embodies the Dao) perceives truth with a mind of emptiness and stillness, embracing heaven and earth within their breast while possessing boundless wisdom. Observing all things within the smallest space, their spirit remains tranquil. They interact with those close yet remain unattached to distinctions of intimacy, neither deliberately pursuing such bonds nor entirely discarding them. Only then can they achieve a realm where all under heaven are as kin and nations harmoniously coexist.

Through logical debate and governance metaphors, this passage expounds the Daoist philosophy of "equalizing all things" (qi wu) and the political ideal of "governing through non-action" (wuwei), rejecting partiality and attachment in conduct.

Gongsun Long was a renowned logician from the State of Zhao during the Warring States period. In his work "Discourse on Reference and Things," he explores the relationship between names and actuality. The core meaning of this passage is:

All things in the world depend on "designation" (naming and definition), yet these designations themselves are not absolutely real. When we say "this is a tree," the concept of "tree" is merely a human construct. Without these designations, things could neither be described nor distinguished.

Gongsun Long points out: designations themselves have no real existence in the world ("designation is what the world lacks"), while concrete things are what truly exist ("things are what the world possesses"). It is unreasonable to forcibly apply artificial concepts to actually existing things.

He further explains that when people refrain from clinging to designations of right and wrong, all things can find their proper place. Just as water and fire have different natures yet each serves its purpose, there's no need to forcibly judge them by standards of right and wrong. The so-called "non-designation" (transcending conceptual labeling) paradoxically reveals how all things fundamentally depend on designation.

Finally, he emphasizes that recognizing the principle that "there are no absolute designations" allows one to understand how all things depend on designation; while understanding this dependence reveals the illusory nature of designations themselves. This dialectical thinking demonstrates the profound insight of ancient School of Names scholars into the relationship between language and reality.

This passage from Gongsun Longzi explores the relationship between "designation" (concepts/names) and "objects" (actual entities), with its core argument being:

Inherently, there are no fixed or unchanging concepts in the world, because each thing possesses its own specific name. Just as Wang Liang excels at charioteering and Li Shou masters calculation, different things have distinct functions and cannot substitute for one another. Forcing inappropriate concepts onto things inevitably leads to confusion between right and wrong.

True "designation" is not a label tied to any particular object. If there were no concrete things in the world, there would be no distinction between "designation" and "non-designation." Yet since objects undeniably exist, we cannot claim concepts are entirely absent. The crux lies in this: all things necessarily involve conceptual recognition (none are beyond designation), yet the concepts themselves are not equivalent to the concrete objects (designation is not the designated).

Like eyes and ears each having irreplaceable functions, every thing carries its unique nature. The sage transcends disputes over right and wrong precisely by understanding concepts merely as tools for knowing—never mistaking names for the things themselves. Were the world devoid of both objects and concepts, debates about designation would naturally cease to exist.

This text reveals the dialectical nature of the name-reality relationship: we must employ concepts to understand the world while recognizing they are not reality itself. Such thinking offers profound insight into the interplay between language and existence.

This passage is from Gongsun Longzi: On Comprehensive Change, primarily discussing the relationship between the names and essences of things, as well as the dialectical relationship between transformation and constancy.

Gongsun Longzi (a representative figure of the School of Names) explores conceptual issues here through a question-and-answer format: When two things are combined, can their original characteristics be preserved? For example, when "white" and "horse" merge to form a "white horse," do the original "white" and "horse" still exist? He points out that after two things are combined, one cannot simply say they remain unchanged (because they have been merged), nor can one say they have completely transformed into something new (because their constituent parts still exist).

The discussion on left and right positions illustrates that these are relative concepts—a single direction cannot be called "two"; only when left and right coexist can they form the relationship of "two." The same applies to change: if a thing remains entirely unchanged, it cannot be called transformation, but if it changes beyond recognition, it becomes difficult to say it is still the same thing. This is like the legendary Kun (a giant fish) transforming into Peng (a giant bird)—it is both the continuation of the same entity and a shift into a different form.

Finally, the text emphasizes that all things are both distinct and interconnected. The sage (one who has attained the Dao) understands this principle and thus transcends distinctions of right and wrong, viewing all things with equanimity. This thought reflects the dialectical thinking of Daoism, which holds that things both maintain their inherent nature and are in constant transformation, with a subtle relationship existing between names and essences.

This passage presents Gongsun Long's logical discourse on the classification and naming of objects. Using the examples of sheep, oxen, and horses, he demonstrates that when two distinct objects are combined, one cannot simply name them after either individual object nor arbitrarily categorize them as a third entity.

For instance, when a sheep and an ox are placed together, one cannot call it solely a sheep or solely an ox, nor should one casually declare it a horse. Sheep have teeth while oxen do not, and though both have horns, their fundamental natures differ. Horses, on the other hand, lack horns and possess tails, making their characteristics entirely distinct from those of sheep and oxen.

He emphasizes that each object possesses its inherent attributes: an ox is naturally an ox, and a sheep is naturally a sheep. Superficial similarities (such as both having horns) should not obscure their essential differences. One sheep plus one ox remain two separate entities—they do not transform into three things or generate a new category. This classification philosophy reflects the rigorous logical thinking of ancient China.

This passage examines the relationship between names and realities, as well as the logic of classification. Gongsun Long uses the example of animal leg counts to illustrate the complexity of conceptual categorization.

Regarding the leg counts of oxen, sheep, and chickens: On the surface, oxen and sheep have fur, while chickens have feathers. When we say "chicken legs," it can refer either to the concept of chicken legs (counted as one) or the actual two legs (counted as two), adding up to three. Similarly, the concept of oxen and sheep legs is one, while their actual four hooves add up to five. This shows that the same term "legs" can yield different conclusions under different classification standards.

Oxen, sheep, and chickens cannot be simplistically grouped together ("not chickens"), just as blue and white, though both colors, have opposing natures (blue belongs to the water element of the east, white to the metal element of the west). Though east and west are opposites, they do not harm each other. The author contrasts horses and chickens, pointing out that horses have practical value while chickens do not, demonstrating that classification must consider actual utility—arbitrary grouping is "wild categorization" (erroneous classification).

The core idea of this passage is: Classifying things cannot rely solely on superficial similarities; one must consider essential differences. Just as the roles of ruler and subject cannot be arbitrarily swapped, conceptual classification must follow inherent logic—otherwise, it leads to confusion between names and realities.

This passage employs color symbolism to expound the philosophical principles of ruler-minister relations. Blue (qing) represents ministers, white symbolizes the sovereign, while yellow signifies the state (as the orthodox color representing legitimate authority). The core message is that only when rulers and ministers each maintain their proper positions can a nation achieve enduring prosperity.

The text observes that blue and white should naturally exist as distinct colors that must not intermix. If ministers (blue) usurp the sovereign's (white) authority, it resembles blue staining white to form an impure "jade-green" hue—an illegitimate state of affairs. The sovereign should govern ministers as metal controls wood in the Five Phases (wuxing) cycle of conquest, but if white cannot overcome blue, national disorder ensues.

The author emphasizes that the sovereign must uphold proper conduct (zhengju) to maintain correct ruler-minister relations. When neither harmonious interaction nor proper restraint exists between them, conflict arises like the chaotic jade-green produced by clashing blue and white. True statecraft requires the sovereign to preserve pure white essence untainted while ministers remain content in their blue station—only thus can the state (yellow) maintain its orthodox position.

This passage discusses the symbolic relationship between colors and political ethics. When blue dye is applied to white fabric and the white cannot overcome the blue, this is called "blue conquering white." If the white, though dyed blue, has not completely disappeared and both colors remain visible simultaneously, it is termed "dual brightness" (liangming) — a state of mutual contention between white and blue, commonly referred to as "jade-green" (qingbai) in folk terminology.

The author argues that rather than choosing the impure jade-green, one should opt for the pure and upright yellow. Yellow represents the central and correct Dao, just as a state requires practical talents like fine horses. Horses serve as metaphors for the upright Dao, while chickens symbolize improper colors (as chickens represent useless fowl). When blue and white mix to form jade-green, it resembles the political chaos caused by rulers and ministers vying for power—this state of "dual brightness" obscures clarity in governance.

The text emphasizes the importance of "names matching reality" (ming shi xiang fu): names should correspond to their substance, and substance should align with their names. All things in heaven and earth—rulers and subjects, fathers and sons, official duties—have their defined names and positions. The sage governs by ensuring names and reality are in harmony, allowing the natural order of heaven and earth to function smoothly, with clear hierarchies. If names and reality do not match, it leads to negligence among superiors and tyranny among inferiors, resulting in systemic disorder. Just as mixed colors appear glaring and discordant, contention between ruler and minister causes internal and external division, corrupting the proper Dao. When names and reality no longer correspond correctly, it becomes impossible to rectify a degenerated tradition.

Through color metaphors, this passage illustrates the importance of the name-reality relationship in political order, asserting that rulers and ministers each fulfilling their roles with names matching reality is the correct way to govern.

Gongsun Long was a renowned logician from the State of Zhao during the Warring States period. In his discourse "On Hardness and Whiteness," he explores a philosophical problem concerning the attributes of a stone. Someone asked: "Can we say a stone possesses three attributes—hardness, whiteness, and its stone-nature?" Gongsun Long replied no. When asked further: "Can we say it has two attributes?" he answered yes.

Here, Gongsun Long explains: When we observe a stone with our eyes, we perceive only its whiteness—a visual attribute—but not its hardness, a tactile quality. Thus, at that moment, we can confirm only two attributes: whiteness and stone-nature. Conversely, when we touch the stone with our hands, we perceive its hardness but not its color, allowing us to confirm only hardness and stone-nature.

He emphasizes: When we confirm whiteness through vision, we cannot claim the stone lacks hardness; when we confirm hardness through touch, we cannot say it lacks whiteness. Yet in neither case can we simultaneously confirm all three attributes (hardness, whiteness, and stone-nature).

Gongsun Long extends this reasoning: If the concept of whiteness did not exist in the world, we could not perceive the stone visually; if the concept of hardness did not exist, we could not describe it tactilely. Hardness, whiteness, and stone-nature are independently existing concepts that cannot be simplistically merged into a single whole. Through this example, he illustrates how various attributes of things (color, texture, form, etc.) exist as distinct cognitive categories. We always apprehend objects through specific attributes, never grasping all their properties simultaneously.

This passage discusses Gongsun Long's famous theory of "Hardness and Whiteness." The core argument states that when observing a hard white stone, the eyes can only perceive whiteness while the hands can only feel hardness—these two attributes appear unified yet exist independently.

For instance, when looking at the stone, the eyes perceive whiteness (color) but cannot detect hardness; when touching it, the hands sense hardness (texture) but cannot perceive whiteness. This demonstrates that "hardness" and "whiteness" exist separately, merely temporarily united within the stone's form. It resembles three objects concealed in one location—we may perceive two at a time, but this doesn't negate the third's existence.

The text particularly emphasizes that this "concealment" isn't deliberate hiding but the natural state of attributes themselves (self-concealed). Just as whiteness naturally exists in the stone and hardness naturally resides within it, these qualities remain complete (mutually fulfilling) yet mutually independent. When we can only perceive some attributes, others don't cease existing—they merely temporarily "depart" from our perceptual range.

Finally, the passage connects this theory to the "Three-Ears" debate recorded in The Annals of Lü Buwei, illustrating how Gongsun Long explored complex relationships between an object's attributes and modes of perception. Using the "hard white stone" example, he demonstrates how different attributes may exist independently, while our senses cannot simultaneously grasp all properties.

This passage discusses the philosophical proposition known as the "Hard and White Debate," which explores the relationship between the attributes of "hardness" and "whiteness" in a stone.

Gongsun Long argues that when we touch a stone with our hands, we perceive its hardness but cannot see its whiteness; when we observe the stone with our eyes, we see its whiteness but cannot feel its hardness. This demonstrates that while both "hardness" and "whiteness" coexist in the same stone, they can be cognitively separated.

He further explains: the eyes are responsible for seeing, and the hands for touching—their functions differ and cannot substitute for one another. Although hardness and whiteness both exist within the stone, when perceived through different senses, they become separated in cognition. It's as if whiteness hides in the eyes (can only be seen, not touched) while hardness hides in the hands (can only be touched, not seen), yet in reality both are inseparable attributes of the stone.

The core of this theory lies in illustrating that while different attributes of a thing coexist within the same object, they can be understood separately in human cognition. Just as a stone simultaneously possesses both hardness and whiteness, we cannot fully grasp all attributes through a single sensory channel at once.

This passage comes from the "Discourse on Hardness and Whiteness" chapter of Gongsun Longzi, discussing the relationship between the attributes of "hardness" and "whiteness." Gongsun Long was a representative figure of the School of Names (Mingjia) during the Warring States period, renowned for his logical reasoning.

The text argues that these two attributes—hardness and whiteness—do not exist solely by depending on concrete objects. Hardness is not confined to stones alone; all things can possess the quality of hardness. Similarly, whiteness is not limited to white stones but exists as an independent attribute in itself. If whiteness must rely on an object to manifest, then the same would apply to colors like yellow or black. If a stone had no color attributes at all, how could it be called a "hard white stone"?

Through logical deduction, the author concludes that attributes like hardness and whiteness exist independently (referred to as "separation" or li). This separation is not artificially created but reflects the natural state of things ("following thus" or yin shi, meaning conforming to natural principles). Rather than laboriously using intellectual cleverness to analyze the relationship between hardness and whiteness, it is better to accept their inherently separate nature.

This discussion embodies the School of Names' core concept of "separating hardness and whiteness" (li jian bai), emphasizing that the attributes of things exist independently and can be distinguished from concrete objects. Such abstract reasoning had a profound influence on the development of logical thinking in later Chinese philosophy.

This passage examines the complexities of human perception and cognition. Through analyzing the examples of "whiteness" and "hardness," Gongsun Longzi reveals how sensory perception constitutes a multifaceted process.

Regarding "whiteness": People assume they see whiteness with their eyes, yet eyes require light (fire) to perceive. However, light itself cannot perceive whiteness, so neither eyes nor light truly "see." What actually perceives is the human spirit (shen, consciousness), yet this spirit must rely on eyes and light to complete the cognitive process. Tracing this chain, we find no definitive "subject" performing the act of "seeing."

Regarding "hardness": When touching a hard object, the hand requires physical contact (striking) to perceive. Yet striking alone cannot know hardness, nor can the hand independently recognize it—ultimate cognition still depends on the spirit. Similarly, the spirit must employ the hand and striking to complete this perception.

Gongsun Longzi observes that while the spirit governs life, its cognition necessarily depends on various sensory faculties. Ears cannot see, eyes cannot hear, feet cannot grasp, hands cannot walk. When observing an object's whiteness, we don't perceive its hardness; when feeling its hardness, we don't see its whiteness. This demonstrates how sensory functions operate independently without mutual substitution.

He thus concludes: All cognitive processes in the world are fundamentally separate (li, disjunctive). Each phenomenon maintains its distinct characteristics without confusion. Sensory faculties operate autonomously without interdependence. Precisely because they don't rely on each other, they don't interfere with one another. The sage (one who attains the Dao) harmonizes with phenomena's inherent nature while maintaining inner stillness, thereby allowing all things to fulfill their proper functions. This leads to the unity of self and world, ultimately transcending distinctions between names and realities.

This exposition embodies Gongsun Longzi's famous "separation of hardness and whiteness" thesis, emphasizing how objects' attributes exist independently while human cognition occurs through distinct sensory channels.

Heaven, Earth, and all they produce are called "things" (物). All beings exist according to their inherent nature without overstepping boundaries—this constitutes "substance" (实, true essence). For instance, selecting suitable timber to build palaces, choosing appropriate materials for carriages and ceremonial garments, appointing capable individuals to fitting official positions, and ensuring internal and external duties are properly assigned—these all exemplify alignment with "substance."

"Substance" must be filled with its proper content without deficiency—this is "position" (位, appropriate placement). When vessels are sized suitably, talents match their responsibilities, and the hierarchy of noble and humble maintains proper order, we see "position" manifested. Overstepping one's designated position (such as officials abusing authority or objects exceeding prescribed standards) violates the requirements of "position." Only when everything occupies its proper place can it be called "correctness" (正, proper order). Materials must conform to regulations, governance must follow rewards and punishments, and divine sacrifices must observe hierarchical distinctions—all must adhere to norms without transgression.

Using proper standards to rectify errors brings what is incorrect back to correctness; using error to disrupt correctness only breeds confusion. What we call "correctness" means rectifying the substance of things, and the key to rectifying substance lies in "rectifying names" (正名, standardizing terminology). Confucius said, "If names be not correct, language is not in accordance with the truth of things"—for when names are correct, substance naturally follows.

When names are correct, they correspond accurately to what they denote. If something is called "that" but does not match the substance of "that," the designation fails; if something is called "this" but does not match the substance of "this," the designation likewise collapses. These failures occur when names and substances are mismatched, and such mismatches inevitably create disorder.

This passage from Gongsun Longzi discusses the crucial relationship between names (ming) and their corresponding realities (shi). He argues that imposing inappropriate names upon things leads to confusion. For instance, if the name "that" (bi) is used to designate a particular object, it must exclusively refer to that object; if "this" (ci) is used, it must strictly correspond to this object. Only when names and realities align perfectly is the relationship correct.

When names correspond accurately to their realities, the world naturally achieves orderly governance. The key lies in ensuring each name precisely matches its intended referent without confusion. For example, using the name "that" to refer to the reality of "this," or vice versa, is fundamentally unacceptable.

True wisdom consists in understanding this principle: knowing a particular achievement does not belong to a certain person means rewards should not be given to them; recognizing a specific crime was not committed by someone means they should not be punished. Names exist to designate realities—political rewards and punishments must align with their corresponding names and realities to be just.

The sage-kings of antiquity placed utmost importance on this alignment of names and realities, exercising great caution in their use of names. Confucius once said that titles and ceremonial objects should not be granted arbitrarily. Through his analysis of the name-reality relationship, Gongsun Long illuminates a fundamental principle of governance: "rectifying names" (zhengming)—ensuring names correspond with realities—is the essential core of the kingly Dao (wangdao).

This passage discusses the relationship between "names" (concepts/labels) and "reality" (actual phenomena). What people value and handle with caution is precisely this connection between names and their corresponding realities. Names serve as tools to designate things and implement teachings, while reality forms the foundation for accomplishing these teachings.

When names become detached from reality, phenomena lose their means of expression through language; conversely, when names lack corresponding realities, the names themselves become meaningless. Thus names are established based on actual phenomena, while phenomena can only be comprehended through their names.

Only when names perfectly correspond with reality can teachings be properly implemented and practical effects fully manifested.
