A Deep Study of Xunzi's 'Jie Pi' Chapter: On the Cognitive Foundations of the Mind—Emptiness, Unity, and Tranquility

Chapter Twelve: Conclusion – The Eternal Significance of the Way of Emptiness, Singularity, and Stillness

Section 1: A Complete Cognitive System

Reviewing Master Xunzi’s text in Jie Bi, we see a complete and precise cognitive system:

The Foundation of Cognition: The Mind (Xin). The Mind is the organ of cognition, the ruler of the body, and the basis of Spiritual Luminosity.

The Conditions for Cognition: Emptiness (Xu), Singularity (Yi), and Stillness (Jing). Emptiness—not allowing existing knowledge to obstruct new reception. Singularity—not allowing multiple cognitive objects to interfere with one another. Stillness—not allowing chaotic mental activity to disturb clear cognition.

The Obstacle to Cognition: Obscuration (Bi). The sources of obscuration are varied—environmental factors, physiological factors, external forces, distance, and psychological factors.

The Goal of Cognition: Great Clarity and Brightness (Da Qing Ming). In the state of Emptiness, Singularity, and Stillness, the Mind reaches this state—all things become visible, analyzable, and properly placed.

The Practice of Cognition: Concentration on the Dao (Yi Yu Dao). Focusing attention on the fundamental Dao, using the Dao as the standard to observe and judge specific things.

The Effect of Cognition: Rectitude (Zheng) and Clarity (Cha). Concentration on the Dao brings rectitude—the will is upright and balanced. Verifying things by it brings clarity—judgment is sharp and free from error.

The Paradigm of Cognition: The Great Man (Da Ren). His brightness rivals the sun and moon, his vastness fills the Eight Extremities, free from obscuration and doubt, sitting in a room yet seeing the Four Seas, dwelling in the present yet discussing antiquity.

This system progresses systematically from foundation to condition, from obstacle to goal, from practice to effect, and from paradigm to ultimate state, forming the most systematic philosophy of cognition in the pre-Qin era.

Section 2: The Unification of Three Levels

Master Xunzi’s "Emptiness, Singularity, and Stillness" actually unifies three levels of issues:

The Epistemological Level: How does man correctly know things$1 —By achieving "Great Clarity and Brightness" through "Emptiness, Singularity, and Stillness."

The Cultivation Level: How does man cultivate his own Mind and nature$2 —By cultivating the state of "Emptiness, Singularity, and Stillness" through "guiding it with principles, nurturing it with purity, and letting nothing incline it."

The Political Level: How does the ruler govern the world$3 —By "Concentrating on the Dao" to govern all things, so that "all things are accomplished without issuing orders for every affair."

These three levels are inseparable in Master Xunzi's thought. Correct cognition is the foundation of cultivation; cultivation is the prerequisite for governance; and governance is the ultimate goal of cognition and cultivation. Together, they form the complete expression of the "Inner Sage and Outer King" ideal in pre-Qin Confucianism.

Section 3: The Interrelationship Among Emptiness, Singularity, and Stillness

Although "Emptiness," "Singularity," and "Stillness" can be discussed separately, they possess a close internal relationship:

Emptiness is the prerequisite for Singularity. Only when the Mind remains open and clear (Empty) can it focus its attention on a single object (Singular). If the Mind is filled with existing knowledge and prejudice, it cannot truly concentrate on the present object of cognition.

Singularity is the condition for Stillness. Only when the Mind is focused in one direction (Singular) will distracting thoughts recede (Still). If the Mind is directed toward multiple directions simultaneously, distracting thoughts will inevitably arise, preventing tranquility.

Stillness is the guarantee of Emptiness. Only when the Mind is quiet (Still) can it maintain a state of clarity and openness (Empty). If the Mind is agitated by distractions, existing knowledge and biases will surge forth, filling the Mind’s space and causing it to lose its clarity.

Thus, Emptiness, Singularity, and Stillness are mutually causal and mutually supportive, forming a virtuous cycle. In this cycle, the Mind continuously deepens its state of clarity, focus, and tranquility, eventually reaching the state of "Great Clarity and Brightness."

Conversely, if this cycle is broken—if the Mind is filled by "already stored knowledge" (loss of Emptiness) → attention disperses (loss of Singularity) → distracting thoughts arise (loss of Stillness) → the Mind becomes even more congested (further loss of Emptiness)—a vicious cycle forms. In this cycle, the Mind becomes increasingly obscured and chaotic, ultimately falling into the dilemma of "resolving doubt with doubt."

Section 4: The Relationship Between Mind and Principle (Li)

A crucial concept in Master Xunzi’s cognitive theory is "Principle" (Li 理):

"Therefore, guiding it with principles, nurturing it with purity.""The Sage indulges his desires and embraces his emotions, yet that which governs them is Principle."

"Principle" (Li) plays a dual role here:

First, Principle is the guiding force for the Mind. "Guiding it with principles" suggests that the Mind is not self-sufficient—it needs the guidance of Li to walk the right path. Without the guidance of Li, the Mind may be dominated by desires and emotions, leading it astray.

Second, Principle is the force that governs desire and emotion. "That which governs them is Principle"—using Li to control desires and emotions. The Sage is not without desires and emotions, but he can use Li to control them, preventing them from spiraling out of control.

What is "Principle"$4 In Master Xunzi’s thought, Li includes at least the following aspects:

One, the inherent laws of things—the Principle of Things (Wu Zhi Li 物之理). Two, the ethical norms of society—the Principle of Ritual (Li Zhi Li 礼之理). Three, the fundamental principles of the Great Dao—the Principle of the Dao (Dao Zhi Li 道之理).

After reaching "Great Clarity and Brightness" through "Emptiness, Singularity, and Stillness," the Mind can clearly perceive "Principle"—including physical laws, ethics, and rationality. Conversely, the understanding of Li further consolidates and deepens the Mind's "Emptiness, Singularity, and Stillness"—because of the understanding of Li, the Mind is less easily disturbed by prejudice, distracting thoughts, and emotions.

Section 5: From Knowledge to Action

Master Xunzi says:

"Knowing the Dao, one can discern; knowing the Dao, one can act; this is one who embodies the Dao."

After knowing the Dao, one must be able to discern (cha), and further, one must be able to act (xing 行). Knowing and being able to act—this is the one who "embodies the Dao" (ti dao zhe 体道者).

There is an important thought here: Cognition is not the end point; practice is. Even the best cognition is empty if it cannot be translated into action; even the profoundest principle is useless if it is not embodied in behavior.

Master Kong also emphasized this:

"If one memorizes the three hundred Odes but is assigned to government duties and cannot manage them; if sent on a mission to the four quarters, he cannot manage independent negotiation—of what use is all that learning$5" (Analects, Chapter 5.11)

The value of knowledge lies in practice; the purpose of cognition is action—this is a fundamental conviction of pre-Qin Confucianism. Master Xunzi’s concept of the "embodier of the Dao" is the concentrated manifestation of this conviction.

Section 6: The Eternal Inquiry: How Does Man Know$6

As this article concludes, the inquiry will not end.

"How does man know$7"—Master Xunzi gave his answer. But this answer is not the conclusion; it is the starting point for new inquiries.

Why are some people able to achieve "Emptiness, Singularity, and Stillness," while the majority cannot$8 Is it due to differences in innate nature, or differences in later cultivation$9

Why is "obscuration" so universal and persistent$10 Is it possible for man to completely eliminate all "obscuration"$11

Can "Great Clarity and Brightness" truly be attained$12 Or is it merely an eternal ideal$13

"The Mind cannot be forced to change its intentions"—If the Mind is truly completely autonomous, why do people still make mistakes and become obscured$14

These questions Master Xunzi may have hinted at directions for answers within his writings, but the final answers likely remain for each thoughtful individual to explore and experience personally.

Because, as Master Xunzi said:

"Knowing the Dao, one can discern; knowing the Dao, one can act; this is one who embodies the Dao."

Understanding must lead to discernment, and understanding must lead to action—true comprehension comes not from reading and thinking, but from personal practice and experience.

"Emptiness, Singularity, and Stillness" is not a method learned from a book, but a cultivation to be continuously practiced in life. Every day, every moment, every thought, is an opportunity for cultivation, and a moment of testing.

Finally, let us conclude with this profound and solemn passage from Master Xunzi:

"Vast and broad, who knows its limits$15 High and far-reaching, who knows its virtue$16 Effervescent and abundant, who knows its form$17 Its brightness matches the sun and moon, its vastness fills the Eight Extremities—this is what is called the Great Man. Ah, where would obscuration be found!"

Vast and broad, who knows its limits$18 High and far-reaching, who knows its virtue$19 Effervescent and abundant, who knows its form$20 Its brightness matches the sun and moon, its vastness fills the Eight Extremities—this is the Great Man. Where would obscuration be found!

May every reader make progress on the path of "Emptiness, Singularity, and Stillness," constantly approaching the state of "Great Clarity and Brightness."
