An In-Depth Study of Xunzi's 'Jiebi' Chapter: On the Cognitive Foundations of the Mind -- Xu, Yi, and Jing
This article offers a thorough analysis of the core proposition in Xunzi's 'Jiebi' (Dispelling Obscurations) chapter concerning the nature of cognition: 'How does a person know$33 Through the mind. How does the mind know$34 Through xu (openness), yi (unity), and jing (stillness).' It systematically elucidates the dialectical relationship among these three concepts, their epistemological significance, and their roots in high antiquity, revealing the systematic rigor and precision of pre-Qin cognitive theory.

Chapter Five: The Mind Is the Sovereign of the Body -- The Status and Function of the Mind
Section 1: The Mind as Master of the Body
Master Xun offered an extraordinarily solemn characterization of the mind's status:
"The mind is the sovereign of the body and the master of spiritual illumination; it issues commands and receives commands from nothing." (xin zhe, xing zhi jun ye, er shenming zhi zhu ye, chu ling er wu suo shou ling)
Each of these three statements contains immensely rich significance.
"The mind is the sovereign of the body" -- the mind is the ruler of the body. In pre-Qin thought, "sovereign" (jun) signified not merely the title of a ruler but the supreme authority of governance. All bodily activities -- walking, speaking, seeing, hearing, moving, stopping -- are directed and commanded by the mind.
"And the master of spiritual illumination" -- the mind is the master of shenming. Shenming here carries two layers of meaning: first, it is a comprehensive term for all mental activity, including thought, judgment, imagination, and emotion; second, it denotes the highest state that the spirit can attain -- the cognitive power to perceive the finest details and see through to the essence of things.
"It issues commands and receives commands from nothing" -- the mind issues commands but accepts no external commands. This is the fundamental hallmark of the mind's sovereignty -- it is autonomous and self-governing, subject to no external compulsion.
Section 2: The Autonomy of the Mind
Master Xun further elaborated on the mind's autonomy:
"It forbids itself, drives itself, takes from itself, gives to itself, acts of itself, stops of itself."
The mind forbids itself, drives itself, deprives itself, acquires for itself, acts on its own, and ceases on its own. These six instances of "itself" (zi) emphatically underscore the mind's complete autonomy -- all the mind's activities are self-initiated and self-determined, not determined by external forces.
This is a philosophical proposition of the utmost magnitude. It means that human cognition and volition are ultimately in one's own hands. The external world may affect the body, but it cannot compel the mind.
"The mouth can be coerced into silence or speech; the body can be coerced into bending or stretching; but the mind cannot be coerced into changing its convictions. What it affirms, it accepts; what it denies, it rejects."
The mouth can be threatened into silence or forced to speak; the body can be forced to bend or stretch; but the mind cannot be coerced into changing its convictions. What the mind deems right it accepts; what it deems wrong it refuses.
Here is a "why" worth pondering: why can the mouth and body be "coerced" while the mind cannot$1
The answer lies in this: the mouth and body are material; they exist in the external world and can be acted upon by external forces. The mind is spiritual; it exists in the inner world, beyond the direct reach of external forces. You can use a blade to force a person to kneel (the body can be coerced); you can use intimidation to silence someone (the mouth can be coerced); but you cannot use any external means to compel a person to genuinely agree with your viewpoint (the mind cannot be coerced).
This insight has wide resonance in pre-Qin thought.
The Lunyu records the Master's words:
"The commander of three armies may be captured, but the will of a common man cannot be taken from him." (Lunyu, "Zihan")
The commander of a great host may be seized, but the will of an ordinary person cannot be taken. Zhi (will) is the mind's direction and determination. This is fully consistent with Master Xun's "the mind cannot be coerced into changing its convictions."
Master Meng said:
"Dwell in the widest dwelling under heaven, stand in the most correct position under heaven, walk the greatest Way under heaven. When achieving one's aims, walk the Way alongside the people; when failing to achieve them, walk the Way alone. Wealth and honor cannot corrupt, poverty and lowliness cannot sway, might and force cannot bend -- such a one is called a great man." (Mengzi, "Teng Wen Gong Xia")
Wealth and honor cannot corrupt, poverty and lowliness cannot sway, might and force cannot bend -- this is the concrete embodiment of "the mind cannot be coerced into changing its convictions" in the domain of moral character.
Section 3: The Mind's "Capacity" and "Choosing"
Master Xun continued:
"Therefore it is said: the mind is capacious; its choosing is without external prohibition; its choosing must naturally manifest; the things it faces are mixed and manifold; yet its ultimate inclination is undivided."
Several key terms require explanation:
"The mind is capacious" (xin rong) -- the mind has the capacity to contain. Its capacity is enormous; it can receive all manner of information and objects.
"Its choosing is without external prohibition" -- the mind's choices face no external constraint. It can freely choose what to accept and what to reject.
"Its choosing must naturally manifest" -- the mind's choices will inevitably show themselves. Whatever you truly affirm or reject in your mind will eventually manifest in your words and actions.
"The things it faces are mixed and manifold" -- the objects the mind faces are diverse and wide-ranging.
"Yet its ultimate inclination is undivided" -- but the mind's deepest tendency is never split.
This passage reveals a deep feature of the mind: though the mind faces manifold objects ("things mixed and manifold"), at the most fundamental level it has a unified direction ("its ultimate inclination is undivided"). This is the inner ground of yi -- the mind naturally tends toward unity and concentration; it is merely that this natural tendency is frequently disrupted by the "mixed and manifold" external world.
There is also an important insight here: "its choosing must naturally manifest." The mind's true state cannot be concealed. No matter how you disguise yourself, your true convictions and will inevitably reveal themselves through one channel or another.
The Daxue (Great Learning) offered a profound discussion of this:
"What is meant by 'making one's intentions sincere' is this: do not deceive yourself. As you loathe a foul smell, as you delight in a beautiful sight -- this is called self-contentment. Therefore the gentleman must be watchful over himself when alone. The petty person in private does all manner of wrong; upon seeing the gentleman, he hastily conceals his faults and displays his virtues. Yet others see him as clearly as if they could see his lungs and liver -- so what use is concealment$2 This is what is meant by: what is genuine within will manifest without. Therefore the gentleman must be watchful over himself when alone."
The mind's true state inevitably manifests outwardly -- "what is genuine within manifests without" (cheng yu zhong, xing yu wai). Others see you as clearly as if they could see your lungs and liver. This is fully consistent with Master Xun's observation that "its choosing must naturally manifest."
Section 4: The Concept of "Mind" in Pre-Qin Thought
"Mind" (xin) occupies an absolutely central position in pre-Qin thought. Virtually all pre-Qin thinkers devoted deep reflection to it.
The Master's theory of the mind:
Though the Master did not frequently use the character xin directly, many of his core concepts -- ren (humaneness), li (ritual propriety), xue (learning), si (reflection) -- were intimately connected with the mind.
"Is humaneness truly far away$3 If I desire humaneness, humaneness is already here." (Lunyu, "Shu Er")
Humaneness is not remote; the moment one's mind desires it, it arrives. This shows that the ground of ren is in the mind; the mind's intention directly determines the direction of moral practice.
"Practicing humaneness depends on oneself -- does it depend on others$4" (Lunyu, "Yan Yuan")
The practice of humaneness depends entirely on oneself (the mind's determination), not on others. This is consistent with Master Xun's "the mind cannot be coerced into changing its convictions."
Master Meng's theory of the mind:
Master Meng was the culminating figure of pre-Qin "mind-learning." He proposed the famous "four sprouts of the mind" (si duan):
"The feeling of commiseration is the sprout of humaneness; the feeling of shame is the sprout of righteousness; the feeling of deference is the sprout of ritual propriety; the sense of right and wrong is the sprout of wisdom. A person's possession of these four sprouts is like his possession of four limbs." (Mengzi, "Gongsun Chou Shang")
The mind innately possesses the germs of humaneness, righteousness, ritual propriety, and wisdom (the four sprouts); these are what make a human being human.
Master Meng also said:
"The office of the mind is thinking. Thinking, one attains it; not thinking, one does not. This is what Heaven has given us. If one first establishes the greater part, the lesser parts cannot usurp it. This alone makes a great person." (Mengzi, "Gaozi Shang")
The mind's function is to think. First establish the mind's leadership (the "greater part"), and the senses (the "lesser parts") cannot disturb it.
This directly echoes Master Xun's "the mind is the sovereign of the body" -- the mind is the master, the senses are subordinate; when the mind is established, the person is upright; when the mind is in disorder, the person is in disorder.
The Guanzi on the mind:
The Guanzi, in the "Xinshu Shang" chapter, contains a passage remarkably close to Master Xun's:
"The mind's position in the body is that of a sovereign. The nine apertures each have their duties, like officials with their allotted roles. When the mind abides in its proper Way, the nine apertures follow principle. When cravings and desires overflow, the eyes cannot see color and the ears cannot hear sound. Therefore it is said: when the ruler above departs from the Way, the subordinates below lose their functions. Do not run in place of the horse -- let it exert its own strength. Do not fly in place of the bird -- let it use its own wings. Do not move ahead of things -- observe their patterns first."
The mind's position in the body is like the sovereign's position in the state. The nine apertures each have their functions, like officials with their assigned duties. When the mind follows the proper Way, the nine apertures each function according to principle. But if cravings fill the mind, the eyes cannot see and the ears cannot hear -- when the ruler above departs from the Way, the subordinates below lose their functions.
This passage is strikingly similar to Master Xun's theory of the mind -- both liken the mind to a sovereign and the senses to officials, both emphasizing the mind's position of mastery.
Section 5: The Mind and "Spiritual Illumination"
Master Xun said the mind is "the master of spiritual illumination" (shenming zhi zhu). This concept of shenming has exceedingly deep cultural roots in pre-Qin thought.
The character shen in high antiquity originally denoted the subtle forces in heaven and earth that transcend ordinary human understanding. The Yijing, "Xici Shang," says:
"What is unfathomable in the interplay of yin and yang is called spirit (shen)."
"Spirit is the word for that which works wonders in all things."
Shen describes the subtle transformations of all things. In the cognitive sense, shenming is the extraordinary insight that the mind exhibits at its zenith -- the ability to grasp the subtle changes of things.
Master Xun's assertion that the mind is "the master of shenming" means that the ground and governance of this extraordinary insight lie in the mind. When the mind is in the state of xu, yi, and jing, it can exercise the function of shenming -- perceiving every subtlety and grasping the pivotal moments of transformation.
The Guanzi, "Neiye," offers a deeply insightful passage on this:
"The numinous qi dwells in the mind; it comes and goes. So fine that nothing can be contained within it, so vast that nothing lies beyond it. The reason it is lost is that agitation causes harm. If the mind can maintain stillness, the Way will settle of itself. The person who has attained the Way -- his principles are well-ordered and his inner self does not deteriorate. The way of regulating desires: nothing among all things can do him harm."
The numinous qi dwells in the mind, coming and going. It is so fine it cannot be grasped by the senses; so vast that it has no limits. The reason people lose it is that agitation causes harm. If the mind can maintain stillness, the Way will settle of its own accord.
The "numinous qi" here is closely related to Master Xun's shenming -- both refer to the extraordinary spiritual power that the mind displays when in its optimal state.
Section 6: The Archaic Origins of the Mind: From Shaman to Philosopher
The concept of the "mind" as the core organ of cognition and spiritual activity has a long cultural history.
In the tradition of shamanism (wu-xi) in high antiquity, the shaman was one capable of communicating with the spirits of heaven and earth. This capacity was believed to arise from a special spiritual state -- concentrating the mind, eliminating stray thoughts, and entering a state of spiritual communion. The core of this state was the "mind."
The Guoyu (Discourses of the States), "Chu Yu Xia," records an important passage about shamans:
"In ancient times, the people and the spirits were not intermingled. Those among the people whose vital essence was unswerving and undivided, who were moreover able to be reverent, composed, and upright within, whose wisdom could align with propriety above and below, whose sagacity could illumine far and near, whose clarity could shed light upon all, whose acuity could hear through all -- upon such ones the luminous spirits descended. Males were called xi; females were called wu."
Those capable of becoming shamans had to possess "vital essence unswerving and undivided" (jingshuang bu xie er) -- a spirit focused and undistracted. This is precisely the archaic form of yi. They also needed "reverence, composure, and uprightness within" (qi su zhong zheng) -- qualities related to the cultivation of jing.
In this description, the spiritual prerequisites of the shaman -- concentration, uprightness, clarity -- share a striking structural resemblance with Master Xun's "xu, yi, and jing." This suggests that Master Xun's cognitive theory may, to some extent, have inherited and transformed the experiences and concepts of spiritual cultivation from the archaic shamanic tradition.
Of course, Master Xun's theory of the mind had entirely departed from the context of shamanism and been transformed into a rational, philosophical theory of cognition. But its deep structure -- achieving extraordinary cognitive capacity through specific forms of spiritual cultivation -- is of the same lineage as the shamanic tradition.
This transformation from "shaman" to "philosopher" was one of the most important developments in the intellectual history of the pre-Qin era. The spiritual cultivation experience of the ancient shamans, through long cultural sedimentation and rational reflection, was gradually transformed into the pre-Qin philosophers' philosophical theory of the mind. Master Xun's "xu, yi, and jing" may be regarded as one important fruit of this transformation.
Section 7: The Limitations of the Mind
Though Master Xun highly affirmed the status and function of the mind, he was by no means a blind worshiper of it. Quite the contrary: the core theme of the "Jiebi" chapter is the revelation that the mind can be obscured -- which in itself is a profound recognition of the mind's limitations.
Though the mind is "the sovereign of the body" and "the master of spiritual illumination," it is not omniscient or omnipotent. The mind can err, can be deceived, can make mistaken judgments -- because the mind is subject to conditions.
The mind can know things clearly only on the premise of "xu, yi, and jing"; the mind can exercise the function of shenming only on the premise that bi has been removed. If these prerequisites are not met, the mind falls into confusion and error.
This recognition of the mind's limitations gives Master Xun's theory a deeply reflective and critical character. He was not saying "the mind is always right" but rather "the mind has the capacity to be right, provided certain conditions are met." This attitude embodies the distinctive rational spirit of pre-Qin thinkers.
