程颢
Studying under Zhou Dunyi (受学周敦颐): The young Cheng Hao and his brother Cheng Yi were sent to study with Zhou Dunyi, who opened their eyes to the unity of cosmology and ethics. Cheng Hao later said that since meeting Zhou Dunyi, he "no longer found joy in anything else" except the pursuit of the Dao.
Humane Governance (仁政实践): As a local magistrate, Cheng Hao governed with compassion and understanding. He once resolved a dispute by appealing to the parties' sense of shame rather than punishing them. His governance embodied his philosophical belief that humaneness is the foundation of all good.
Recognizing the Spring Breeze (如沐春风): Students who studied under Cheng Hao described the experience as being bathed in a spring breeze. His warmth and openness created an atmosphere of free inquiry that contrasted with the more rigorous style of his brother.
The Inscription of "Ren" (识仁说): Cheng Hao's most important philosophical text, "On Understanding Humaneness" (识仁篇), argued that ren (humaneness) is not an external principle but the very substance of the self — "forming one body with Heaven, Earth, and the ten thousand things."
仁者，以天地万物为一体，莫非己也。
"The humane person forms one body with Heaven, Earth, and the ten thousand things — nothing is outside the self." — The cosmic scope of humaneness.
天理二字，却是自家体贴出来。
"The words 'heavenly principle' — I experienced them directly in my own person." — Knowledge through lived experience, not mere study.
万物一体。
"All things are one body." — The fundamental unity of existence.
学者须先识仁。仁者浑然与物同体。
"The student must first understand humaneness. The humane person is seamlessly one with all things." — Humaneness as the starting point of philosophy.
天地万物之理，无独必有对。
"The principle of all things under heaven: nothing exists alone — everything has its opposite." — The bipolar nature of reality.
For Cheng Hao, ren is not just a virtue but the very substance of reality. To be humane is to feel the suffering and joy of all things as one's own — to "form one body with Heaven and Earth."
Heaven's principle (天理) is not external to the self but is discovered within one's own experience. This insight foreshadowed Lu Jiuyuan's later emphasis on the mind.
Cheng Hao's method of cultivation — maintaining inner calm and clarity amid external disturbance. His "Letter on Settling the Nature" (定性书) argues that the sage responds to things naturally, without forced detachment.
All things exist in complementary pairs — yin and yang, activity and stillness, self and other. Understanding this bipolar structure is key to understanding the cosmos.
"On Understanding Humaneness" — A short but profound text arguing that humaneness is the substance of the self and the cosmos.
"Letter on Settling the Nature" — A philosophical letter on maintaining inner equanimity amid external circumstances.
"Surviving Works of Master Mingdao" — Collected writings and recorded conversations.
Cheng Hao's philosophy of humaneness speaks directly to modern concerns about empathy, connection, and ecological awareness. His vision of "forming one body with all things" offers a philosophical foundation for environmental ethics. His emphasis on lived experience over mere intellectual study resonates with contemporary approaches to mindfulness and embodied cognition. The warmth and openness he brought to teaching remind us that philosophy is not just about ideas but about how we treat one another.
