Xunzi's 'Jie Bi' (Unveiling Concealment): On the Wholeness of the Dao, Cognitive Limitation, and the Fortune of Being Unobstructed

Section 2: The Intellectual Background of Master Xunzi’s Discussion of "Bi"

To deeply understand the thesis of Master Xunzi’s "Jie Bi," one must examine the background against which his thought arose. Master Xunzi lived in the late Warring States period, when the debates of the Hundred Schools of Thought had raged for centuries. Since Master Confucius inaugurated Confucianism in the late Spring and Autumn period, various schools emerged, each asserting its own doctrine in contention. By Master Xunzi’s time, the ideas of the Hundred Schools had flooded forth like surging rivers, unstoppable.

Faced with this intellectual landscape where "the various schools followed different paths and held different intentions" (百家殊方，指意不同), Master Xunzi felt a deep sense of apprehension. Why$11 Because, in his view, the doctrines of the various schools were not entirely wrong—they each grasped a certain aspect of the Dao and revealed one side of the truth. However, precisely because each school grasped only one aspect of the Dao, they believed they had grasped the entirety of the Dao, and they used this singular perspective to attack others, resulting in severe intellectual chaos and cognitive disaster.

This anxiety is fully reflected in other chapters of Master Xunzi's work. In the chapter "Fei Shi Er Zi" (非十二子, Against the Twelve Philosophers), Master Xunzi systematically criticized twelve contemporary thinkers. Although the angle of criticism in "Fei Shi Er Zi" differs from that in "Jie Bi"—the former focusing on socio-political impact, the latter on epistemological roots—their core concern is identical: how to establish a holistic, impartial intellectual stance amidst the contention of the Hundred Schools.

Master Xunzi’s ability to propose the theory of "Bi" is inseparable from his profound insight into the structure of human cognition. In other sections of "Jie Bi," Master Xunzi analyzed the cognitive mechanism of the mind in detail. He stated:

"How does man know the Dao$12 I say: the mind. How does the mind know$13 I say: by being empty, unified, and still." (人何以知道？曰：心。心何以知？曰：虚壹而静。)

This statement is crucial. Master Xunzi believed the mind inherently possesses the capacity to know the entirety of the Dao, and the method for this is "empty, unified, and still" (xu yi er jing). "Empty" (Xu) means not allowing existing knowledge to obscure new cognition; "Unified" (Yi) means being focused and undivided; "Still" (Jing) means being calm and not agitated. Yet, why could the various masters not achieve "empty, unified, and still"$14 Precisely because they had each accumulated deep learning and insights in specific areas, and these accumulations subsequently became obstacles obscuring their further cognition. This is the inverse of being "unobstructed by accumulation" (bu bei yu cheng ji)—they were precisely obscured by their own "accumulations."

This raises a deeper question: How does knowledge itself become an obstruction$15 Is the pursuit of knowledge harmful$16

Master Xunzi’s answer is subtle and dialectical. Knowledge itself is not harmful; what is harmful is "believing it sufficient and adorning it" (以为足而饰之)—believing that the knowledge one has attained has exhausted the entire Dao, and consciously beautifying and decorating this prejudice until it appears complete. "Jie Bi" states this clearly: "Those who possess partial knowledge observe one corner of the Dao, yet fail to recognize it as such. Therefore, they believe it sufficient and adorn it." (曲知之人，观于道之一隅，而未之能识也。故以为足而饰之。) The character "adorn" (shi, 饰) is used perfectly. If a piece of incomplete jade is not adorned, people immediately see its flaw; but once cleverly adorned, its defect may be hidden, perhaps even leading people to mistake it for perfection. The theoretical systems established by the various schools are this kind of "adornment"—they use sophisticated argumentation and elegant rhetoric to decorate a partial view into the entirety of the Dao.

This insight by Master Xunzi is groundbreaking in the history of pre-Qin thought. Earlier thinkers either attacked their opponents' conclusions as wrong (like Master Mencius criticizing Yang Zhu and Mozi) or pointed out flaws in their methods (like Master Mozi criticizing the Confucian preoccupation with ornate rituals), but few systematically analyzed from an epistemological height why these schools committed such errors. Master Xunzi’s "Jie Bi" chapter is precisely this kind of epistemological reflection.

It is also worth noting that Master Xunzi did not criticize the various schools from an entirely external standpoint. As a Confucian scholar himself, he maintained a sober reflective awareness of Confucian tradition. By citing the opening passage, "The obstruction of Master Bin Meng was household chaos" (昔宾孟之蔽者，乱家是也), using a specific historical lesson, he indicated that the problem of "Bi" is not exclusive to any single school but is a universal cognitive predicament for humanity. Furthermore, the reason Master Confucius, whom he revered, was great was not because he mastered some unique secret knowledge, but because he was "benevolent, wise, and yet unobscured" (仁知且不蔽)—Master Confucius’s superiority lay precisely in his freedom from being obscured by any single aspect, enabling him to be inclusive and draw inferences from one point to others.

This lends Master Xunzi’s critique a universality that transcends partisan disputes. He is not saying, "We Confucians are right, and you other schools are wrong," but rather, "Each of you has seen one aspect of the Dao, but you all mistake that one aspect for the whole; this is your fundamental error." This manner of criticism inherently embodies Master Xunzi’s scholarly magnanimity of being "unobstructed."
