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

Chapter 4: "Cattle and sheep then come to graze upon it, and thus it becomes as barren as that" — Secondary Harm and Complete Loss

Section 4.1 "Cattle and sheep then come to graze upon it": The Second Destruction of the Sprouts of Goodness

If "cutting down with axes and adzes" was the first harm, then "cattle and sheep then come to graze upon it" (Niu yang you cong er mu zhi) is the second, and even more fatal, harm.

After the mountain wood is cut, new shoots (sprouts) emerge, but they are very young and fragile. If cattle and sheep are then allowed to graze on the mountain, they will eat these young shoots to extinction. The shoots do not even get a chance to grow before they are eliminated. Thus, the mountain becomes "as barren as that" (ruo bi zhuo zhuo ye)—completely bare, without a single tree.

The correspondence in this analogy is:

• Cutting with axes and adzes → Initial erosion of conscience by material desire (felling already grown trees).
• Sprouting of new shoots → Recovery of conscience during the night (nourishment of yeqi, causing sprouts of goodness to re-emerge).
• Cattle and sheep grazing → Daytime actions repeatedly destroying the newly recovered sprouts of goodness (daytime actions restrain and extinguish).

Why is the destruction by "cattle and sheep" more fatal than the "axes and adzes"$45 Because the axes cut down large trees, but the roots remain, allowing new shoots to grow. Cattle and sheep, however, graze on the newly emerging sprouts, preventing them from growing, and eventually, the roots themselves die due to lack of nourishment from photosynthesis.

The profound meaning here is: the most fatal harm to the human conscience is not a single, massive blow, but repeated, continuous erosion that eradicates the sprout of goodness the moment it begins to recover—namely, the daily, pervasive infringement of minor vices. A person might make one major mistake and regret it afterward, and the conscience can still recover. But if a person continually commits unrighteous acts, every time the conscience begins to revive (during the nighttime "yeqi"), it is immediately extinguished by the actions of the day ("daytime actions restrain and extinguish it"). Repeating this cycle, the conscience will ultimately be lost entirely.

Section 4.2 The Significance of the "Cattle and Sheep" Imagery

Why did Mencius choose "cattle and sheep" as the imagery for the second harm$46 "Cattle and sheep" carry rich symbolic meanings in pre-Qin literature.

The Analects (Chapter 3, 17th chapter) records:

Zigong wished to abolish the offering of the ram during the ceremony of announcing the new month. The Master said: "Ci! You love the ram, but I love the rite."

Here, "sheep" relates to "ritual" (li). The ritual of announcing the new month required a ram; Zigong wanted to save the ram, but Confucius felt the rite could not be abandoned. However, the "cattle and sheep" here are not sacrificial animals, but livestock for grazing. Grazing cattle and sheep is an everyday, utilitarian activity aimed at satisfying human dietary needs. In pre-Qin pastoral society, cattle and sheep were symbols of wealth (Shijing, Xiaoya, Wuyang): "Who says you have no sheep$47 Three hundred are in the flock. Who says you have no cattle$48 Ninety are young bulls." Abundance is described by the multitude of cattle and sheep. When cattle and sheep graze and eat the new shoots, it represents the direct destruction of spiritual growth by material needs.

There is a subtle implication here: the people who graze the cattle and sheep might be the same people who felled the wood, or they might be different. The first group cut down the big trees for material; the second group ate the new shoots for livestock. Their goals differ, but the harm to the mountain is cumulative. The first group felled the large trees, and the second group’s livestock ate the new sprouts.

On the level of the human heart, this analogy suggests that the forces eroding human conscience are not singular but multi-faceted and cumulative. Major desires (like greed for wealth, lust, or lust for power) are the "axes and adzes," cutting down the already developed aspects of goodness. Minor habits (like daily laziness, compromise, or following the crowd) are the "cattle and sheep," nibbling away at the newly emerging sprouts of goodness. Major desires are easily noticed and guarded against, but minor habits are often ignored because they are too commonplace—yet it is precisely these ignored minor habits that ultimately lead to the complete loss of conscience.

The Analects (Chapter 4, 26th chapter) records:

Zixia said: "When the great virtues do not cross the boundaries, minor virtues that come and go are acceptable."

Zixia believed that minor departures from perfection were tolerable. However, from the perspective of Mencius’s "cattle and sheep grazing," it is precisely the constant "coming and going" of "minor virtues" that leads to the repeated nibbling away of the sprouts of goodness, ultimately resulting in their complete demise. Even if the "great virtues" do not cross the "boundaries" (major junctures), the continuous indulgence in "minor virtues" is like cattle and sheep eating new shoots daily, eventually leaving the mountain (the human heart) "barren."

Here, Mencius’s perspective forms an interesting contrast with Zixia’s. Zixia emphasizes major principles and righteousness, allowing for flexibility in minor details; Mencius profoundly recognized the cumulative effect of "minor details"—a dike a thousand li high collapses because of an ant hole.

Section 4.3 "As barren as that": The Image of Complete Loss

"As barren as that" (Ruo bi zhuo zhuo ye)—meaning utterly bare. Zhao Qi’s annotation: "Zhuozhuo means the appearance of having no trees or plants." A mountain that was once lush is now utterly bare, with not a single blade of grass growing—this is a shocking sight.

Why use such a stark image$49 Because Mencius wants people to face the severity of the reality. The state of the human conscience after it has been lost is like a barren mountain—empty, with no trace of goodness. This explains why bystanders "assume there has never been good timber"—they conclude this person never possessed a conscience.

The word "zhuozhuo" has other uses in pre-Qin literature. The Book of Songs, Major Odes (Daya, Song Gao), describes a lofty mountain: "Lofty is that great mountain, reaching to the heavens. From that mountain descended the spirits, giving birth to Fu and Shen." Although not directly using "zhuozhuo", the tradition of describing tall mountains is long-established. In contrast, the Book of Songs, Major Odes (Daya, Han Lu), states: "Gazing at that dry hill slope, the briars and thorny shrubs are dense and abundant. How cheerful and amiable is this gentleman! His sustenance is abundant and joyous." "Zhen shu ji ji" (dense briars and shrubs) contrasts sharply with "zhuozhuo" (barrenness)—the former symbolizes the beauty of a flourishing forest, the latter the tragedy of utter destruction.

It is worth pondering: A barren mountain is not incapable of recovery. If the cutting and grazing cease, after years of rest and recuperation, vegetation can indeed grow back. Likewise, even if a person's conscience has been entirely lost, if they cease the erosion of material desire and engage in long-term cultivation, the conscience can recover. However, recovery presupposes "stopping the destruction"—if the axes never stop, and the cattle and sheep are never removed, the mountain can never recover. Similarly, if material desires continue, and unrighteous acts persist, the conscience can never be restored.

This is the concrete manifestation of Mencius’s later statement: "Thus, if they obtain nurture, nothing will fail to grow; if they lose nurture, nothing will fail to diminish."
