On Human Nature and Emotions

Reading mode

Holistic Paraphrase
The Zuo Zhuan records Zichan stating: Emulate the brightness of heaven (heaven possesses the three lights of sun, moon, and stars, hence it is called bright), and follow the innate nature of earth (earth nurtures all things). Heaven and earth transform to produce the six qi (energies) and utilize the five phases—the five phases correspond to the five inherent human qualities, while the six qi permeate the six human emotions. Yi Feng further elaborates: The five phases manifest in humans as nature (benevolence, righteousness, propriety, wisdom, and faithfulness), and the six pitch-pipes manifest in humans as emotions (joy, anger, sorrow, happiness, liking, and disliking). The five natures are internal and belong to yang 🌞, harmonizing the five organs; the six emotions are external and belong to yin 🌙, connected to the six body parts. When emotions overpower nature, disorder ensues; when nature governs emotions, order prevails. Nature arises from within, while emotions are triggered by external factors; the two intertwine in a subtle and inseparable manner.

The Shuowen Jiezi defines: Emotion (qing) is the yin energy in humans, associated with desires and preferences; nature (xing) is the yang energy in humans, embodying inherent goodness. The Xiaojing Yuanshenqi emphasizes: Nature is the inherent endowment of humans, while emotion belongs to the flowing yin numbers, connecting to the five organs; thus, nature is the root, and emotion is the branch. Nature is tranquil and constant, while emotion is active and changes with circumstances; the interplay of movement and stillness forms a subtle interaction.

Heshang Gong annotates: The spirit of the five natures is called hun (yang, masculine), and the spirit of the six emotions is called po (yin, feminine), reaffirming that nature is yang and emotion is yin. When the six qi correspond to the six emotions: Liking belongs to yang (yang energy favors growth), disliking belongs to yin (yin energy favors destruction), anger is wind (the clash of yin and yang resembles human anger), joy is rain (the harmonious blending of yin and yang brings joy), sorrow is gloom (worry and闭塞 like darkness), and happiness is brightness (cheerfulness and relaxation bring light).

Han Dynasty scholars linked emotions and nature to organs and seasons: Lunheng states the heart governs the five organs, with joy in the liver, anger in the lungs, sorrow in the kidneys, and happiness in the spleen. Yi Feng, however, associates the six emotions with the six bowels: Liking → bladder (water favors forward movement), anger → gallbladder (lesser yang abundance causes anger), disliking → small intestine (summer growth dislikes falsity), joy → large intestine (metal treasures things, hence joy), happiness → stomach (earth nurtures all things, hence happiness), sorrow → triple burner (exhaustion of yin-yang house causes sorrow). Though the systems differ, their principles are interconnected.

Yi Feng further integrates the five phases' directions with the nature-emotion system:

East 🌳: Nature benevolence, emotion anger → thievery and robbery (dominated by Hai and Mao)
South 🔥: Nature propriety, emotion disliking → integrity and promotion (dominated by Yin and Wu)
West ⚔️: Nature righteousness, emotion joy → generosity and celebration (dominated by Si and You)
North 🌊: Nature wisdom, emotion liking → greed and索取 (dominated by Shen and Zi)
Center ⛰️: Nature faithfulness, emotion sorrow → fairness and remonstrance (dominated by Xu and Chou)
Upper 🎭: Nature disliking, emotion happiness → treachery and illness (dominated by Chen and Wei)

Nature and emotions are interdependent: Greed requires thievery to act, and thievery relies on greed to take effect. Rulers avoid the Zi-Mao punishment days (yin并行), and favor Wu-You auspicious days (yang并行). Exhaustion of water and wood gives rise to treachery (Chen-Wei), while extreme metal and fire lead to self-punishment and sorrow (Xu-Chou), revealing the dialectical law of mutual containment in prosperity and decline.

🧠 In-Depth Understanding

Core Concepts 💡

Dual Structure of Nature and Emotion: Innate human goodness (yang five natures) and emotional fluctuations (yin six emotions) create internal tension.
Heaven-Human Correspondence: The five phases and six qi strictly correspond to human organs and emotions, forming a holographic model of the cosmos and the human body.
Dynamic Balance: Emotions overpowering nature lead to chaos; nature governing emotions leads to order, emphasizing the importance of letting innate nature guide emotions.
Punishment and Clash Principles: Earthly branch punishments (Zi-Mao, Chen-Wei, Wu-You, Xu-Chou) reveal the spatiotemporal patterns of emotional conflicts.

Modern Interpretation 🌟

Science of Emotional Management: The ancient theory of "nature governing emotions" aligns highly with modern emotional intelligence (EQ) theory, stressing rational regulation of emotions.
Mapping to Personality Psychology: The five natures (benevolence, righteousness, propriety, wisdom, faithfulness) correspond to basic personality dimensions, while the six emotions (joy, anger, sorrow, happiness, liking, disliking) cover the core emotional spectrum.
Insights into Biological Rhythms: The link between earthly branches, time, and emotions offers a cultural perspective for biorhythm research (e.g., anger at Mao hour, disliking at Wu hour).
Environmental Psychology: The six qi (yin, yang, wind, rain, gloom, brightness) are classical expressions of environmental factors affecting human psychology.

Practical Value ⚡

Decision-Making Reference: Avoid "Zi-Mao punishment days" (days of emotional conflict) for important matters; choose "Wu-You harmony days" (days of rational dominance).
Emotional Regulation: When angry, reflect on the wood nature of the east (benevolence); when sad, remember the earth nature of the center (faithfulness), establishing emotional cognitive anchors.
Interpersonal Strategies: Identify others' emotional patterns (e.g., greed for索取, thievery for scheming) and adopt corresponding interaction strategies.
Health Preservation: Excessive emotions damage corresponding organs (anger harms the liver, joy harms the heart, etc.), requiring balancing through the five phases.

Philosophical Reflections 🤔

Debate on Human Nature: The ancient dialectic between innate goodness (yang energy goodness) and emotional desires (yin energy desires) foreshadows modern discussions on human nature.
Dilemma of Free Will: "Emotions come from outside" points to the environmental determinism of emotions, creating philosophical tension with "nature arises from within" and ontological autonomy.
Cyclical Worldview: The rise and fall and mutual punishments of the five phases reveal the nonlinear characteristics of emotional development, negating mechanical determinism.
