Chapter 18 · The Ultimate Inquiry: Why Does Chinese Civilization Alone Cherish "Xiaoman"$15

I. Why Guard Against "Fullness"$16—The General Principle of the Dao of Heaven's Waxing and Waning

Having come this far, we have already touched, repeatedly, from the dimensions of etymology, astronomy, phenology, philosophy, myth, ritual institutions, and musical pitch, upon the central theme of "guarding against fullness, prizing modesty." Let us now pose, and answer, once and for all, the core question running through this entire essay—why does Chinese civilization guard against "fullness" so warily$17

The most fundamental answer lies in a general principle running through Heaven, Earth, and humanity alike—the waxing and waning of fullness and emptiness.

The Book of Changes, hexagram Feng, "Commentary on the Judgment"—"when the sun reaches its zenith, it begins to decline; when the moon reaches fullness, it begins to wane; the fullness and emptiness of Heaven and Earth wax and wane with the times"—is the most concentrated expression of this general principle. In the cosmology of our Chinese ancestors, the whole of Heaven and Earth was an eternally revolving system of the waxing and waning of fullness and emptiness—nothing can remain "full" forever; whatever is full must become empty, whatever is complete must become deficient, whatever flourishes to its utmost must decline. This is an iron law that bends to no human will.

In such a cosmos, why is "fullness" fearsome$18 Because "fullness" is the very summit of "brimming," and the summit of brimming is the starting point of emptiness. The sun at noon (fullness) must tilt; the full moon (fullness) must be eclipsed; the arrogant dragon (fullness) must have cause for regret; the tilting vessel filled to the brim (fullness) must overturn. "Fullness" means that one has already reached the very end of the ascending channel, and what follows can only be a fall. Thus, the wariness toward "fullness" is, at its root, a preemptive vigilance against that inevitable "decline," "deficiency," and "overturning" yet to come.

Once we understand this, we come to understand that deeply ingrained sense of "anxious foreboding" (忧患意识) within Chinese civilization. The "Great Treatise" (Xici Zhuan) of the Book of Changes asks: "Was it not perhaps with a sense of anxious foreboding that the author of the Changes composed this work$19" (作《易》者，其有忧患乎？)—was it not, perhaps, out of a profound sense of foreboding that the author of the Book of Changes composed it$20 This foreboding stems precisely from a deep insight into "the waxing and waning of fullness and emptiness"—precisely because one understands well that "fullness must inevitably lead to deficiency," one maintains, at the very moment when nothing has yet become "full," when there is still room to rise, a sober-minded vigilance, never letting oneself (or all things) slide toward that perilous "great fullness."

II. Why No "Great Fullness"$21—The Survival Wisdom of Seeking Completeness Through Incompleteness

A further inquiry: if "fullness" is to be guarded against, why not simply abolish "small fullness" as well$22 Why preserve "small fullness" specifically, while abolishing only "great fullness"$23

This is precisely the most exquisite, most dialectical point of Chinese wisdom.

Were there no "small fullness" either, and all things forever remained in a state of "not-fullness" (emptiness, deficiency, insufficiency), this too would be undesirable—the tilting vessel "tilts when empty" (unstable when empty); the mi grass, without the fullness of yang qi, could support no flourishing of life whatsoever; the wheat, without filling with grain (small fullness), would have no hope of harvest at all. Pure "not-fullness" (emptiness) is scarcity, stagnation, lifelessness—equally a violation of the Dao of Heaven.

The exquisiteness of Chinese wisdom lies precisely in this: between the two extremes of "fullness" (inevitable deficiency) and "not-fullness" (scarcity), it precisely singles out an optimal solution—"small fullness." "Small fullness" is the true, substantial abundance of "filling every hollow before advancing" (not scarcity), and also the room to spare of "great accomplishment seems flawed" (not great fullness). It enjoys the benefits of "fullness" (vitality, hope, abundance), while avoiding the dangers of "fullness" (decline following utmost flourishing, reversal at the extreme). It is the perfect balance of abundance and restraint, the wise unity of fullness and modest withdrawal.

This is precisely the survival wisdom of "seeking completeness through incompleteness"—preserving a touch of "incompleteness" (not reaching great fullness) is, precisely, in order to fulfill that "completeness" (a lasting, sustainable perfection). A thing that forever pauses at "small fullness" achieves, instead, the most enduring "completeness"—because it forever remains within the ascending channel, forever has room to continue growing, forever has "its function never fail." A thing that pursues "great fullness," though seemingly attaining "completeness," in fact slides immediately into "deficiency," and thereby loses "completeness" instead.

The Most High said: "The crooked becomes whole; the bent becomes straight; the hollow becomes full; the worn becomes new; having little, one gains; having much, one is bewildered" (曲则全，枉则直，洼则盈，敝则新，少则得，多则惑; Daodejing, Chapter 22). What is crooked can, instead, be preserved whole; what is bent can, instead, become straight; what is hollow can, instead, become full; what is worn can, instead, become new; taking little, one gains; craving much, one becomes bewildered. The three characters "the hollow becomes full" (洼则盈) strike especially close to the principle of "Xiaoman"—preserving hollowness (modesty, not-fullness) can, instead, achieve true fullness. "Having little, one gains; having much, one is bewildered"—being content with "small fullness" (little), one gains something instead; coveting "great fullness" (much), one falls, instead, into bewilderment and calamity. "Small fullness with no great fullness" is precisely the calendrical crystallization of this series of dialectical wisdoms—"the crooked becomes whole," "the hollow becomes full," "having little, one gains."

III. How Has "Xiaoman" Become the Spiritual Undertone of an Entire Civilization$1

The final inquiry is this: how has this wisdom of "full yet not overflowing, guarding against fullness, prizing modesty" become the spiritual undertone of the entire Chinese people, permeating every corner of our culture$2

The answer, perhaps, lies in the "universality" and "practicality" of this wisdom.

It is universal—from governing a state ("preserving fullness, guarding peace") to managing a household ("modesty receives gain"), from self-cultivation ("never satisfied in learning") to conducting oneself in the world ("leaving room to spare in all things"), from aesthetics ("blank space and restraint") to health cultivation ("diminishing rich flavors, letting the will know no anger")—the wisdom of "full yet not overflowing" applies everywhere. It is not specialized knowledge confined to any one field, but a fundamental attitude running through every field at once.

It is practical—it is not an abstract principle suspended in the void, but a wisdom of daily life that can be put into practice in every specific act. A Chinese person, upon achieving success, knows to withdraw modestly (not self-satisfied); upon seeing flowers half-open, knows to appreciate them (not seeking them fully bloomed); when speaking, knows to leave something unsaid (not saying everything); upon achieving fame and accomplishment, knows to step back (not clinging to it)—all of this is the natural expression, in the ethics of daily life, of the wisdom of "Xiaoman."

And what is most remarkable of all is that our ancestors found so ingenious a vessel to seal this vast and profound wisdom within—the name of a single solar term. "Xiaoman"—these two characters, arriving punctually before every Chinese person, year after year, with the turning of the calendar, silently remind us: it is enough for things to attain a small fullness; there is no need for great fullness; only by being full yet not overflowing can things endure. What a superior mode of cultural transmission this is! It relies on no sermonizing, no indoctrination, but instead, through the rhythm of Heaven and Earth's motion, through the cycle of a single solar term, transmits a civilization's most central wisdom, year after year, silently as the nourishing rain, to generation after generation of descendants.

When we gaze once more upon the two characters "Xiaoman" today, what we gaze upon is not merely a farming season, not merely a solar term, but a civilization's wisdom in facing fullness and emptiness, success and failure, the rise and fall of human life—a wisdom that, across several thousand years, has grown only more profound: full yet not overflowing, brimming yet able to remain empty, approaching fullness but not yet full, always leaving room to spare. This is "Xiaoman."
