Chapter One: Introduction -- An Ancient and Eternal Inquiry

Section 1: "How Does a Person Know$1" -- The Starting Point of the Inquiry

In the history of human thought, certain inquiries possess such immense force and such profound implication that they can stir the hearts of readers across a thousand years. At the very opening of his "Jiebi" (Dispelling Obscurations) chapter, Master Xun posed just such an inquiry:

"How does a person know$2" (ren he yi zhi)

These few words, seemingly brief, cleave through chaos like a bolt of lightning -- for they ask not "what" a person knows, nor "what" a person ought to know, but rather "by virtue of what" a person is capable of knowing at all. This is a reflection upon cognition itself, a foundational inquiry into the very ground upon which "knowing" stands.

Master Xun's answer is equally concise and powerful:

"Through the mind." (yue: xin)

The mind is the ground of knowing. Yet the inquiry does not end here; it presses deeper, layer upon layer:

"How does the mind know$3 Through xu, yi, and jing -- openness, unity, and stillness." (xin he yi zhi$4 yue: xu yi er jing)

From "How does a person know$5" to "How does the mind know$6", Master Xun accomplished a twofold inquiry. The first points toward the organ of human cognition -- the mind; the second points toward the inner conditions by which the mind is capable of cognition -- xu (openness), yi (unity), and jing (stillness). The structure of these two inquiries is like peeling layers of a bamboo shoot, moving from the outer to the inner, from the surface to the depths, ultimately arriving at the deepest ground of cognitive activity.

Why did Master Xun pose his inquiry thus$7 Why is the "mind" the ground of knowing rather than the ears and eyes$8 Why does the mind's knowing require the three conditions of xu, yi, and jing$9 Why, in discussing cognition, did Master Xun devote so much attention to the phenomenon of bi (obscuration)$10 What manner of intellectual world lies behind these questions$11

Section 2: The Intellectual Position of the "Jiebi" Chapter

Within the corpus of Master Xun's writings, the "Jiebi" chapter occupies an absolutely pivotal position. The title "Jiebi" means "dispelling obscurations" -- jie is to untie, to remove; bi is to cover, to obscure. The central aim of the entire chapter is to reveal how human cognition becomes obscured, and how such obscuration may be dispelled to reach the state of "great clarity and luminosity" (da qingming).

In this chapter, Master Xun constructed a complete and rigorous theory of cognition:

First, on the status of the "mind" -- the mind is the sovereign of the body and the master of spiritual illumination. Second, on the conditions of "knowing" -- xu, yi, and jing. Third, on the harm of "obscuration" -- the universal affliction of people is to be obscured by one partial view and thereby blinded to the greater principle. Fourth, on the method of "dispelling obscuration" -- guide it with reason, nourish it with clarity. Fifth, on the state of "great clarity and luminosity" -- among all things, none that has form goes unseen, none that is seen goes undiscussed, none that is discussed loses its proper place.

These five dimensions interlock, together constituting the most systematic and most rigorous epistemology of the pre-Qin era.

Section 3: The Scope and Method of This Study

This study unfolds along two principal perspectives:

First, the perspective of pre-Qin thought. Taking Confucianism and Daoism as its main axes, and drawing broadly upon the various schools of pre-Qin philosophy, this study situates Master Xun's cognitive theory within the entire intellectual world of the pre-Qin period. Our aim is not "comparison" but the discovery of "resonance" -- those shared concerns, kindred images, and mutually illuminating insights that recur in the writings of different thinkers.

Second, the perspective of high-antiquity myth and folk tradition. Pre-Qin thought did not arise from nowhere; it was deeply rooted in the myths, religious beliefs, and folk wisdom handed down from high antiquity. The concept of the "mind," the imagery of "clarity and luminosity," the notion of "spiritual illumination" -- all possess exceedingly ancient cultural roots. We shall trace these concepts back to their archaic foundations, in hopes of more deeply understanding the cultural soil from which Master Xun's thought grew.

In method, this study adheres to the following principles:

First, extensive citation of original pre-Qin texts, grounding arguments in textual evidence rather than speculation. Second, persistent asking of "why," pursuing the reasons behind every important proposition. Third, striving for depth expressed in accessible prose, supporting fluent exposition with rigorous scholarship. Fourth, strict limitation to pre-Qin and high-antiquity intellectual sources, citing nothing from the Han dynasty or later.

Section 4: Overview of the Chapter Structure

The full text comprises twelve chapters. Chapter One serves as the introduction, setting out the genesis and method of the study. Chapters Two through Four respectively explore in depth the three core concepts of xu, yi, and jing. Chapter Five discusses the status and function of the "mind." Chapter Six discusses the types and causes of "obscuration." Chapter Seven discusses the state of "great clarity and luminosity." Chapter Eight discusses the practical cultivation of "unity with the Way." Chapter Nine explores the cultural origins of "mind" and "knowing" from the perspective of high-antiquity myth and folk tradition. Chapter Ten discusses resonances and mutual illuminations among pre-Qin thinkers. Chapter Eleven discusses the relationship between cognition and the art of governance. Chapter Twelve offers a comprehensive summation.
