Xunzi's 'Jie Bi' (Unveiling Concealment): On the Wholeness of the Dao, Cognitive Limitation, and the Fortune of Being Unobstructed
This paper offers an in-depth interpretation of the 'Jie Bi' chapter in Xunzi, investigating the epistemological origins of the 'calamity of obstruction' described by the Pre-Qin philosophers. By analyzing the concept that 'the Dao is constant in its entirety yet utterly transformative,' the essay reveals the dilemma of human cognition being fixated on 'a single corner' and elucidates the transcendental value of Confucius's 'benevolence and wisdom unhindered,' aiming to understand how to escape cognitive bias.

Section 3: "Unity" (Yi)—Focus without Dispersion
"Unity" (Yi)—Focus without dispersion.
"Yi" means singular focus. "The mind is never not full, yet there is such a thing as unity." (Xin wei chang bu man ye, ran er you suo wei yi.) The mind is always active with various thoughts (full), yet one must maintain focus (Yi).
"Yi" does not mean focusing on only one aspect (which would lead to obstruction)—it means being fully invested when cognizing a specific thing, without being distracted by other thoughts. "Yi" is an attitude toward cognition, not the scope of cognition. The scope of cognition should be comprehensive (guaranteed by "Xu"), while the attitude toward cognition should be focused ("Yi"). True "Yi" means being fully invested in understanding each domain sequentially, and after grasping it, being able to let it go and move to the next domain—repeating this process ultimately leads to a comprehensive and deep understanding of all domains.
Master Confucius is the best model here. When studying the Odes, he was fully engaged (Xing yu shi); when studying rites, he was fully engaged (Li yu li); when appreciating music, he was fully engaged (Cheng yu yue). But he was not invested in only one domain; rather, he achieved deep knowledge in each area in turn—this is the unity of "Yi" and "Xu": "Yi" ensures depth and focus in each act of cognition, while "Xu" ensures breadth and comprehensiveness across the scope of cognition.
