An In-depth Interpretation of Mencius' 'The Trees of Ox Mountain' Chapter: The Core of Innate Goodness and Cultivation of Mind and Nature

Chapter 15: Recovering the Heart and Seeking the Heart — Doctrine of Cultivation

Section 15.1 Why the Conscience is "Abandoned" — A Deeper Analysis of the Causes of Loss

Since the conscience is innate and original, why is it "abandoned" (fang shi)$13 This is the greatest theoretical challenge to the doctrine of inherent goodness.

This question can be phrased more precisely: If goodness is innate to human nature, where does evil come from$14

Section 15.2 "Seeking the Lost Heart" — The Core of Cultivation Practice

Mencius’s method of cultivation can be summarized in one phrase: "Seeking to recover that lost heart" (qiu qi fang xin)—finding back that lost conscience.

What are the specific methods for "seeking the lost heart"$15 Synthesizing Mencius’s entire work and related pre-Qin texts, we can summarize them as follows:

(A) Reducing Desires (Gua Yu)

Mencius (Jinxin II): "Cultivating the heart/mind is best achieved by reducing desires."

Reducing desires is the best way to nurture the heart/mind (nurture the conscience). Desires are the "axes and adzes." The fewer the desires, the less the conscience is cut, and the easier it is for the conscience to recover and be maintained.

However, "reducing desires" is not "eliminating desires." Mencius does not demand that people completely eradicate desire (that would be the path of Laozi or Yang Zhu), but demands the reduction of unnecessary desires and the control of excessive desires. This is like managing a forest—not forbidding all felling (which is unrealistic), but limiting the amount of cutting so that it does not exceed the natural recovery capacity of the wood.

(B) Reflecting Upon Oneself (Fan Qiu Yu Ji)

Mencius (Gongsun Chou I): "Benevolence is like archery. The archer rectifies himself before he shoots; if he misses the target, he does not blame those who surpassed him, but reflects on himself."

Mencius (Li Lou I): "If one loves others but they do not respond with affection, reflect on one's own benevolence. If one governs others but they are not governed, reflect on one's own wisdom. If one shows propriety to others but receives no reciprocal courtesy, reflect on one's own reverence. Whatever action fails to yield the desired result, reflect upon oneself. If one’s person is upright, the world will turn to him."

"Reflecting upon oneself" (Fan qiu yu ji)—When encountering problems, instead of blaming others, one should examine oneself. This is the concrete practice of "Cao" (holding the heart)—by reflecting, one directs attention back to the inner self, inspecting whether one's conscience is still present.

(C) Accumulating Righteousness (Ji Yi)

Mencius (Gongsun Chou I): "This Vast, Flowing Qi is born from the accumulation of Righteousness, not seized by a sudden act of righteousness."

"Ji Yi"—Accumulating righteous deeds. The haoran zhi qi is "born from the accumulation of Righteousness"—accumulating moral strength through continuous righteous action. This is like continuously planting and nurturing a forest, rather than planting a forest all at once, so that the forest gradually recovers.

(D) Preserving the Heart and Nurturing Nature (Cun Xin Yang Xing)

Mencius (Jinxin I): "To exhaust one's heart is to know one's nature. To know one's nature is to know Heaven. To preserve one's heart and nurture one's nature is how one serves Heaven."

"Cun xin yang xing" is the general outline of cultivation. "Jin xin"—to fully exert the heart’s function (thinking, reflecting, discerning good and evil). "Zhi xing"—to know one’s nature (goodness) through exhausting the heart. "Zhi Tian"—to know Heaven through knowing nature (because nature comes from Heaven’s decree). "Cun xin"—to preserve the conscience from being lost. "Yang xing"—to nurture one’s nature so it continues to grow. "Shi Tian"—to serve Heaven through preserving the heart and nurturing nature.

This sequence reveals the complete system of Mencius’s cultivation theory: starting with "exhausting the heart" (fully utilizing the heart’s function), leading to "knowing nature," then "knowing Heaven," and finally "preserving the heart" and "nurturing nature" to "serve Heaven." The starting point is "exhausting the heart" (the concrete activity), and the endpoint is "serving Heaven" (unification with the Heavenly Dao).

(E) Cautious Solitude (Shen Du)

Zhongyong: "Nothing is more visible than what is hidden, and nothing is more manifest than what is minute. Therefore, the superior man is careful about his solitude."

Daxue: "What is meant by making the will sincere is not to deceive oneself. As if hating a bad smell, as if loving a beautiful sight—this is called self-reverence. Therefore, the superior man must be careful about his solitude."

"Shen Du"—Maintaining moral awareness when alone and unwitnessed. This is closely related to Mencius’s doctrine of "Yeqi": Nighttime is the time of solitude and the time of conscience recovery. If one cannot maintain moral awareness during the night (solitude), but instead indulges desires, then even the "night energy" cannot restore the conscience, and one truly becomes "not far from birds and beasts."

Section 15.3 Historical Cases: Preservation and Loss of the Sprouts of Goodness

There are many historical examples in pre-Qin literature that confirm Mencius’s theories of "seeking the lost heart" and "holding the heart."

(A) King Zhou of Shang — A typical case of complete conscience loss.

The Book of Documents (Taishi Shang) records King Wu’s words:

"Now, Shang Zhou, despises Heaven above and casts down calamity upon the people below. He wallows in drunkenness and lust, daring to practice savage tyranny. He punishes the innocent by clan extermination, and promotes officials by lineage. He uses their palaces, terraces, ponds, and extravagant clothing to ruin your tens of thousands of surnames. He burns and roasts the loyal and good, and cuts open pregnant women."

King Zhou indulged in wine and women, tyrannized the people, burned the loyal and good, and cut open pregnant women—his actions far exceeded the bounds of human relations. Analyzing this through the lens of the "Wood of Ox Mountain" chapter: King Zhou was not inherently a tyrant. He initially possessed sprouts of goodness and a conscience, but under the corrosion of power and indulgence of desire ("cut down with axes and adzes"), his sprouts of goodness were eroded step by step. Every act of atrocity ("daytime actions") further destroyed the remaining sprouts ("restrained and extinguished it"). Day after day ("cut down day after day"), the conscience was eventually lost entirely ("night energy insufficient to be preserved"), leading him to be "not far from birds and beasts."

The Book of Documents (Xibo Kan Li) records Zu Yi warning King Zhou: "Heaven has already ended the fate of our Yin dynasty. We consult the great tortoise, and none dare pronounce it auspicious. It is not that the former kings do not assist my later descendants, but that the King's licentious amusement has cut him off from the mandate. Therefore, Heaven abandons me."

Zu Yi warned King Zhou: Heaven has terminated the destiny of the Shang dynasty. What was the King’s response$16 "'Alas! Is my life not ordained by Heaven$17 What can be done about it$18'" This represents the state after the conscience is completely lost—a person can no longer listen to any admonition, can no longer feel the distinction between good and evil, and is completely numb.

To use the analogy of the "Wood of Ox Mountain": King Zhou’s state at this point is "as barren as that"—not a single tree on the mountain, not even a sprout can grow. Bystanders would indeed "assume there was never any timber"—concluding that King Zhou was always a tyrant and never had a conscience. But Mencius would say: "Is this the true disposition of man$19" (Shi qi ren zhi qing ye zai$20)—No! King Zhou became this way as a result of the "axes and adzes" (lust for power) "cutting down day after day"—it was not his innate nature.

(B) King Xuan of Qi — A typical case where sprouts of goodness exist but are obscured.

Mencius (Liang Hui Wang I) records the famous dialogue between Mencius and King Xuan:

The King said: "I have a sickness; I am fond of pleasure (women)." Mencius replied: "In the past, Your Majesty loved your concubines... If Your Majesty is fond of pleasure, and shares that fondness with the common people, what harm is there to Your Majesty$21" The King said: "I have a sickness; I am fond of wealth." Mencius replied: "In the past, Duke Liu was fond of wealth... If Your Majesty is fond of wealth, and shares that fondness with the common people, what harm is there to Your Majesty$22"

King Xuan admits to being "fond of pleasure" and "fond of wealth"—these are his "axes and adzes," eroding his conscience. But Mencius does not deny these desires; he guides King Xuan to connect his personal desires with the needs of the common people—"share that fondness with the common people." This is one method of "nurturing": not completely eliminating desire, but guiding it toward goodness.

More importantly, Mencius discovered that King Xuan still possessed sprouts of goodness:

The King said: "My strength is enough to lift a hundred jun, but not enough to lift a single feather; my eyesight is clear enough to see the tip of an autumn hair, but not the cartloads of firewood before me." Will the King agree$23 ... He said: "I heard Hu He say: The King was sitting in his hall, and someone was leading an ox past the hall. The King saw him and said: 'Where is this ox going$24' The reply was: 'It is to be used to consecrate a new bell.' The King said: 'Let it go! I cannot bear to see it tremble in fear, as if it is being led to death without any crime.' The reply was: 'Then shall we abandon the consecration of the bell$25' The King said: 'How can we abandon it$26 Exchange it for a sheep!'" ... He said: "This heart is enough to rule the kingdom! The common people will all think Your Majesty is benevolent, and I, your subject, know well that Your Majesty cannot bear it."

When King Xuan saw the ox about to be slaughtered for the ceremony, he could not bear its "trembling in fear" (husu), and ordered it be exchanged for a sheep. This "heart that cannot bear" (bu ren) is precisely the "heart of alarm and compassion" that Mencius speaks of—the sprout of Benevolence. Although King Xuan's conscience had been heavily cut by "axes and adzes," the "sprouts of goodness" still remained. Mencius’s task was to help the King realize this ("This heart is enough to rule the kingdom!") and guide him to expand this sprout to governing the state.

This case perfectly illustrates the core idea of the "Wood of Ox Mountain" chapter: Although the human conscience is eroded, as long as there is a "sprouting of new shoots," there is a possibility of recovery; the key is "obtaining nurture"—finding the right method to nourish and expand the sprouts of goodness.

(C) Shun — A typical case of fully expanded sprouts of goodness.

Mencius (Li Lou II) records:

"Shun was enlightened about the myriad things and perceptive about human relationships; he acted from benevolence and righteousness, rather than acting to practice benevolence and righteousness."

The reason Shun became a Sage was not that his nature was inherently better than others ("the difference between man and beast is slight"—the difference between people is small), but because his sprouts of goodness received full nourishment and expansion.

Mencius (Jinxin II):

"When Shun lived deep in the mountains, dwelling with wood and stone, roaming with deer and swine, the difference between him and the people of the deep mountains was but slight. But when he heard a good word or saw a good deed, his reaction was like the breaking open of a river or a great watercourse—powerful and irresistible."

When Shun lived deep in the mountains, the difference between him and the reclusive people was "slight" (ji xi)—very small. But Shun possessed a key quality: once he heard a good word or saw a good deed, his sprouts of goodness surged forth like a broken dam, irresistible. This is the best example of "If they obtain nurture, nothing will fail to grow"—once the sprout of goodness is triggered and nurtured, its power to grow is limitless.

To use the "Wood of Ox Mountain" analogy: Shun was like a mountain with excellent soil—once seeds appeared ("hearing a good word or seeing a good deed"), a dense forest immediately grew. Those who lost their conscience were like Ox Mountain—though the soil was also good ("not without the sprouting of new shoots"), because they were "cut down day after day" and "grazed upon," nothing could grow.
