An In-depth Interpretation of Mencius' 'The Trees of Ox Mountain' Chapter: The Core of Innate Goodness and Cultivation of Mind and Nature
This paper takes the "The Trees of Ox Mountain" chapter from Mencius' "Gaozi" as its core text, integrating it with pre-Qin philosophical literature to deeply analyze the argumentative structure of innate human goodness, the mechanisms by which external environments harm the mind and nature, and the philosophical foundations and cultivation practices of the theory of innate goodness.
Chapter 29: Comprehensive Reflection: The Significance and Limitations of Pre-Qin Philosophy of Heart/Nature
Section 29.1 Significance
The greatest significance of pre-Qin theories of human nature (especially Mencius’s doctrine of inherent goodness) is that they established the dignity and moral agency of the individual.
Man has dignity because he possesses inherent goodness—he is not merely a biological organism but a moral agent. Man possesses moral agency because his goodness is innate, internal, and inalienable—no external force can fundamentally eradicate his goodness.
The "Wood of Ox Mountain" chapter expresses this conviction in a vivid manner: even under the most adverse circumstances, even when goodness has been most severely eroded, the "root" of human goodness still exists and has the possibility of recovery. This conviction is the starting point for all moral cultivation, all political reform, and all social progress.
Section 29.2 Limitations
The pre-Qin theories of human nature (including Mencius’s doctrine of inherent goodness) also have limitations:
First, the explanation for the "Origin of Evil" is not entirely thorough. As noted, Mencius outlines the process by which goodness is eroded but fails to fundamentally explain how this "process of erosion" began in the first place.
Second, insufficient attention is paid to the differences in the degree of goodness among individuals. Mencius asserts that "everyone has sprouts of goodness," but the sprouts seem stronger in some people (like Shun, whose goodness surges "like a breached river" upon hearing a good word) than others (who commit evil daily without realizing it). What accounts for this difference$30 Mencius does not fully explain.
Third, the specific methods of cultivation require more detail. "If held, it exists; if released, it perishes" is a profound principle, but how does one "hold"$31 Under what circumstances does one "hold"$32 What methods are used to "hold"$33 Mencius did discuss these concrete operational issues (e.g., "Cultivating the heart is best achieved by reducing desires," "accumulating righteousness," "preserving the heart and nurturing nature"), but they are not yet systematic or exhaustive.
However, these limitations should not negate the value of pre-Qin philosophy of nature. The fact that pre-Qin thinkers proposed such profound theories of human nature over two millennia ago is itself a great achievement in the history of human thought. The task of later scholars is to deepen and perfect this thought on the basis of the pre-Qin foundation, rather than to overthrow or deny it.
