Chapter Four: "Achievement and Enterprise Are Seen Through Change" — The Praxis of Change and the Sage's Way of Governing the World

I. Three Levels of "Change"

"Achievement and enterprise are seen through change" — this is the fourth layer of the passage's progression, turning from epistemology to praxeology. The preceding portions discuss how yao and xiang operate and how fortune and misfortune manifest; this portion addresses how gong ye — actual governing achievements — arise from "change" (bian).

In the pre-Qin context, bian (change) operates on at least three levels:

First level: changes in hexagram lines. This is the most immediate level. Lines have "changing lines" (old yang becomes yin, old yin becomes yang), and hexagrams have "transformed hexagrams" (the original hexagram transforms into the resulting hexagram). By observing changing lines and transformed hexagrams, one can discern the direction of a situation's development. The Xici zhuan (Part I) states: "To trim and tailor transformation is called 'change'; to extend and carry it out is called 'penetration.'" Change is the tailoring of transformation; penetration is the extension of change.

Second level: changes in the historical situation. The great transformations of the world — dynastic succession, the migration of customs, the revision of institutions. The Xici zhuan (Part II) enumerates the "fashioning implements in reverence of images" associated with thirteen hexagrams, demonstrating how the sages created tools and institutions in response to the changing demands of their eras:

"After Bao Xi passed away, Shen Nong arose. He hewed wood to make plowshares and bent wood to make plow handles; the benefit of plowing and weeding he used to instruct all under heaven — this was presumably taken from the hexagram Yi (Increase). He set midday as market time, gathered the people of the world, and assembled the goods of the world; they traded and withdrew, each obtaining what they needed — this was presumably taken from the hexagram Shi He (Biting Through)."

From Fu Xi to Shen Nong to the Yellow Emperor, Yao, and Shun, each advance in civilization was "taken from" a certain hexagram image — meaning the sage discerned from the hexagram image the demands of historical change and accordingly created new tools and institutions. This is the direct embodiment of "achievement and enterprise are seen through change."

Third level: transformation of mind and character. The Xici zhuan (Part I) states: "When things reach their extreme, they change; through change, they penetrate; through penetration, they endure." This proposition transcends specific hexagram techniques and historical events, rising to the level of universal existential wisdom — when affairs develop to their uttermost limit, change must occur; only through change can there be penetration; only through penetration can there be endurance. In the Lunyu (Zi Han), when the Master faced dire straits, he said: "Has heaven not yet destroyed this culture$19" This spirit of refusing to abandon adaptive transformation even in extremity is a living embodiment of "when things reach their extreme, they change."

II. Why "Achievement and Enterprise" Rather Than "Fortune and Misfortune"$20

It is worth pondering deeply: the preceding clause says "fortune and misfortune appear without," while this clause says "achievement and enterprise are seen through change." Why the shift in terms$21 Why not "achievement and enterprise appear without" or "fortune and misfortune are seen through change"$22

The difference in diction reveals two distinct levels of concern:

"Fortune and misfortune" is a judgment about individual circumstances — personal gain and loss, honor and disgrace, safety and peril.

"Achievement and enterprise" is an evaluation of collective endeavor — the actual efficacy of governing a state, securing the realm, and benefiting the world. It does not simply "appear" from the hexagram image but can only be realized through active "change" — reform, adaptation, adjustment.

This distinction is crucially important. It means that the Zhouyi is not merely a manual for divining individual fortune and misfortune; it is, even more so, a canonical text guiding the sage's timely adaptation and world-shaping enterprise.

The Xici zhuan (Part I) states:

"The Yi is that by which the sage plumbs the depths and scrutinizes the incipient. Only through depth can he penetrate the aspirations of all under heaven; only through incipience can he accomplish the affairs of all under heaven; only through spirit can he act without haste yet swiftly, without going yet arriving."

"Plumbing the depths" is epistemological profundity; "scrutinizing the incipient" is the acute perception of the earliest stirrings of change. Through the Yi, the sage studies those ji — those almost imperceptible harbingers of change — and thereby acts appropriately before change has fully unfolded. This is the deeper meaning of "achievement and enterprise are seen through change."

III. A Historical Case: King Wen's Elaboration of the Yi and the Rise and Fall of Zhou

The historical case that best illustrates "achievement and enterprise are seen through change" is the relationship between King Wen of Zhou and the Zhouyi.

The Shiji (Records of the Grand Historian, "Basic Annals of Zhou") records:

"The Lord of the West had been on the throne for some fifty years. During his imprisonment at Youli, he presumably expanded the Eight Trigrams of the Yi into the sixty-four hexagrams."

According to tradition, King Wen, during his imprisonment at Youli, developed the Eight Trigrams of Fu Xi into the sixty-four hexagrams and appended the hexagram statements. Why did King Wen elaborate the Yi while in captivity$23 Because he found himself at the extremity of qiong — his personal freedom was stripped away, and the fate of his lineage hung by a thread. It was precisely in this extreme situation that he needed "change" — through deep study of the patterns of transformation in the Way of heaven and earth, he sought the path out of adversity and toward the building of a great enterprise.

Indeed, the rise of the Zhou was itself a history of "change." In the oath before the Battle of Muye recorded in the Shangshu ("Mu shi"), King Wu declared:

"Now the Shang king Shou heeds only the words of his consort, has heedlessly abandoned his sacrificial duties and gives no answer to the spirits, has heedlessly cast aside the lineage of the former kings and does not employ them..."

The Shang king Zhou's "refusal to change" — his refusal to adapt to the demands of the times, his obstinate persistence in erroneous governance — led to his downfall. The "change" of King Wen, King Wu, and the Duke of Zhou — adapting to the transfer of heaven's mandate, creating new institutions of rites and music — achieved the enterprise of the Zhou dynasty lasting several centuries.

The Xici zhuan (Part II) also states explicitly:

"The rise of the Yi — was it not in the middle antiquity$24 The maker of the Yi — was he not beset by anxiety and affliction$25"

And further:

"The rise of the Yi — was it not in the final age of the Yin and the flourishing virtue of the Zhou$26 Was it not in the affair between King Wen and Zhou Xin$27 Therefore its words are perilous. The wise person who contemplates its tuan (judgment) statements will understand more than half."

The Yi was produced precisely amid the heaven-and-earth-overturning great transformation between the Yin and Zhou. Its words tend toward "peril" — pervaded by a sense of anxiety and affliction — precisely because its maker profoundly experienced the urgency and criticality of "change." "Achievement and enterprise are seen through change" is not an empty slogan but a profound summation of the monumental historical transformation of the Yin-Zhou transition.
