Chapter Two: "The Xiang Is That Which Images This" — The Levels of Xiang and the Epistemology of Images

I. The Subtle Difference Between Xiang (Image) and Xiang (Imaging)

Immediately following "effecting" comes "imaging." The original text reads: "The xiang is that which images this."

At first glance, "effecting" (xiao) and "imaging" (xiang) seem near-synonymous, but careful analysis reveals an important distinction.

"Effecting" emphasizes the dynamic process of imitation — it is a verb-like act.

"Imaging" emphasizes the static relationship of resemblance — it is a state-like presentation.

In other words, the yao is "doing" (modeling after the movements of heaven and earth), while the xiang is "showing" (presenting the configurations of heaven and earth). The yao is process; the xiang is outcome. The yao is microscopic fluctuation; the xiang is the macroscopic pattern.

A passage in the Xici zhuan (Part I) neatly confirms this distinction:

"The sage sets up the hexagrams and observes the images, appends judgments and thereby clarifies fortune and misfortune."

Note the order: first "set up the hexagrams," then "observe the images." Hexagrams are composed of lines; the lines move and the hexagram forms; when the hexagram forms, the image appears. That is to say, the image is the holistic picture that naturally emerges after the lines have moved.

This accords perfectly with what we observe in the natural world. The images of heaven — the trajectories of the sun, moon, and stars — are not single points but holistic patterns presented by the superposition of countless dynamic movements. Likewise, after the six lines have each undergone their changes, the hexagram image they jointly compose is a kind of "imaging" — imaging a certain characteristic relational configuration between heaven and earth.

II. The Multiple Dimensions of Xiang in Pre-Qin Thought

Xiang (image) is an extremely central and complex concept in pre-Qin thought. To understand "the xiang is that which images this" in depth, we must examine the multiple layers of meaning that xiang carries in different contexts.

First layer: celestial images. The Zuozhuan (Duke Zhao, Year 1) cites Zi Chan: "The affairs of heaven always manifest as images." The affairs of heaven always present themselves in the mode of "images." Solar eclipses, lunar eclipses, comets, rainbows — all are "images" of heaven. In the pre-Qin era, observing images to regulate the calendar was among the most important political activities. The opening of the "Canon of Yao" in the Shangshu states: "He then commanded Xi and He, reverently to accord with august heaven, to calculate and image the sun, moon, and stellar markers, and respectfully to bestow the seasons upon the people." "To calculate and image the sun, moon, and stellar markers" — this is the systematic observation and modeling of celestial images.

Second layer: phenomenal images. The Xici zhuan (Part I) states: "The sage, having perceived the abstruse complexities of all under heaven, fashioned likenesses of their forms and appearances, imaging what is fitting for each thing — and therefore they are called 'images.'" Here xiang functions as a verb — rendering the deep and complex things of the world into apprehensible likenesses, making them available for cognition and communication.

Third layer: trigram images. Each of the Eight Trigrams has its image: Qian is heaven, Kun is earth, Zhen is thunder, Xun is wind, Kan is water, Li is fire, Gen is mountain, Dui is marsh. These images are high-level abstractions of the fundamental elements of the natural world. The Shuogua zhuan extensively unfolds the images of the Eight Trigrams:

"Qian is heaven, is roundness, is the sovereign, is the father, is jade, is metal, is cold, is ice, is deep red, is a fine horse, is an old horse, is a lean horse, is a piebald horse, is the fruit of a tree."

A single Qian trigram can symbolize so many things! This demonstrates that "imaging" is not a rigid one-to-one mapping but rather an associative network connected by categorical affinity.

Fourth layer: conceptual images. This is the most abstract level. The Xici zhuan (Part I) states: "Writing cannot exhaust speech, speech cannot exhaust meaning — then can the sage's meaning never be perceived$13 The Master said: 'The sage establishes images to exhaust meaning.'" This passage is profoundly significant — language and writing cannot exhaust the sage's meaning, but "images" can. Why$14 Because images are not linear logical deductions but holistic intuitive presentations. When a hexagram image is set before a person of penetrating understanding, they can apprehend from it subtle meanings that words cannot convey.

Wang Bi, in his Zhouyi lüeli ("Summary of the Principles of the Zhouyi," chapter "Clarifying Images"), developed this brilliantly:

"Images are that which bring forth meaning. Words are that which clarify images. Nothing exhausts meaning so well as images; nothing exhausts images so well as words. Words are born of images, and therefore one may trace words to observe images. Images are born of meaning, and therefore one may trace images to observe meaning. Meaning is exhausted through images; images are made manifest through words."

Wang Bi further proposes "grasping the meaning and forgetting the image, grasping the image and forgetting the words" — which is entirely congruent with Master Zhuang's idea of "catching the fish and forgetting the trap." The Zhuangzi ("Outer Things") states:

"The fish trap exists for the sake of the fish; once you have the fish, forget the trap. The snare exists for the sake of the rabbit; once you have the rabbit, forget the snare. Words exist for the sake of meaning; once you have the meaning, forget the words."

Yet we must note: Wang Bi's theory of "forgetting the image" is a development of Wei-Jin metaphysics (xuanxue). In the original pre-Qin context of the Xici zhuan, the image is not a tool to be transcended but the rightful bearer of the sage's meaning. "The xiang is that which images this" — the image faithfully images the Way of heaven and earth, and is itself a presence worthy of reverence.

III. Why Does "Effecting" Come Before "Imaging"$15

The original text places "the yao is that which effects this" before "the xiang is that which images this." This order is deliberate.

From a generative perspective: first the lines move, then the image forms. The yao is the basic unit from which images are constituted, just as in the cosmos the movement of yin and yang (effecting) precedes the presentation of myriad forms (imaging). The Xici zhuan (Part I) states: "One yin and one yang — this is called the Dao." The alternating movement of yin and yang is the most fundamental level; the profusion of myriad images is the macroscopic manifestation of that movement.

From an epistemological perspective: "effecting" before "imaging" also suggests a cognitive pathway — we grasp the holistic configuration (image) by observing the dynamic process (effecting) of things, not the reverse. This strikingly parallels the modern systems-theory principle that "process is prior to structure."
