Professor Wang's Midnight Lesson: Why the Suffering Self Cannot Sleep

Wang Defeng teaches that the self which cannot surrender is the self that cannot sleep. No algorithm can solve a problem that is not computational.

Wang Defeng — professor of philosophy at Fudan University, interpreter of Hegel and Heidegger, devoted student of Wang Yangming's School of Mind, and one of the most unexpectedly beloved lecturers on the Chinese internet — has spent his career asking a question that philosophy has always asked and that modern life makes newly urgent: why do we suffer?

His answer is not what you might expect from a man who has read everything Marx ever wrote. It is not economic. It is not structural. It is, at its core, a question of the self — specifically, of a self that has forgotten how to yield.

"Modern people," he says in one of his most-watched lectures, "are exhausted not because they work too hard, but because they resist too much. They resist their fate. They resist their nature. They resist the simple fact that they are not in control."

Lie awake at two in the morning, and you will know exactly what he means.

The School of Mind and the Body That Already Knows

Wang Yangming — the fifteenth-century philosopher whose thought Wang Defeng has spent decades teaching — proposed a radical idea: that moral knowledge is not acquired from outside but is already present within every human being. He called it liangzhi — innate moral knowing, the original intelligence of the heart-mind that perceives what is right before reason has a chance to complicate it.

Wang Defeng extends this insight beyond ethics. The body, he suggests, has its own liangzhi — its own innate knowing, its own orientation toward health and balance and rest. It knows when it is hungry and when it is full. It knows when it is tired. It knows, with a certainty that no sleep tracker can improve upon, when it needs to stop.

The problem is not that the body does not know. The problem is that the self — the anxious, effortful, controlling modern self — will not listen.

The self that cannot surrender is the self that cannot sleep. It lies awake not because it is not tired, but because it cannot stop being itself long enough to rest.

This is the insight that Wang Defeng's philosophy offers to the insomniac: that sleeplessness is not a medical problem to be solved but a philosophical one to be understood. The body is not broken. The self is simply in the way.

Movement: Unity of Knowing and Doing

Wang Yangming's most famous teaching is zhixing heyi — the unity of knowing and doing. True knowledge, he argued, is never merely theoretical. If you genuinely know something, you act accordingly. A person who claims to know that rest is necessary but continues to work until midnight does not, in Wang Yangming's terms, actually know it. They have information. They do not have knowledge.

Applied to the body in the hours before sleep, this principle is clarifying. If you know that vigorous exercise close to bedtime disrupts sleep — and you do it anyway — you do not yet know it in the way that matters. Knowledge that does not change behaviour is not yet knowledge. It is opinion.

The evening movement that serves sleep is gentle, intentional, and honest about what the body needs at this hour: a walk that winds down rather than winds up, stretches that invite release rather than demand performance, the kind of physical attention that says to the body, I hear you, and I am responding. This is zhixing heyi in practice — the unity of understanding and action, the body and the self moving in the same direction for once.

Nutrition: The Wisdom of Eating Less

Wang Defeng is drawn to Buddhist thought as well as Confucian, and Buddhism has always understood something that modern nutrition science is only beginning to confirm: that the digestive system, like the mind, needs periods of genuine rest.

The Buddhist tradition of not eating after noon is, in its original context, a practice of renunciation. But its physiological logic is sound: the body that is not digesting can devote its resources to other forms of restoration. The body that is digesting a large meal at eleven at night is working, not resting, regardless of what the eyes are doing.

The evening meal, in this framework, is an act of consideration — a gift given to the body in advance of the night's work. Warm, simple, easily digested: a congee of millet or rice, a broth of red dates and longan that nourishes the heart and calms the spirit, a cup of sour jujube seed tea that the classical physicians prescribed for the mind that will not quiet. Not a reward for the day's effort. A preparation for the night's restoration.

The self that eats lightly in the evening is a self that has, in some small way, already begun to yield.

The Bedtime Ritual: The Practice of Sitting Still

Wang Yangming prescribed jingzuo — quiet sitting — as a foundational practice for students of the School of Mind. Not meditation in the Buddhist sense, not prayer in the religious sense, but simply the practice of sitting without agenda: allowing the mind to settle, the breath to slow, the accumulated noise of the day to begin its natural dispersal.

He recommended it particularly for people whose minds were too active — people who thought too much, planned too much, worried too much. People, in other words, who sound very much like the inhabitants of the twenty-first century.

The bedtime ritual, understood through this lens, is a form of jingzuo extended across the whole evening: the deliberate, progressive quieting of the self. Lights dimmed. Screens silenced. The body moved through warmth — a bath, a foot soak, the slow release of held tension — and then settled into the sleep environment with the same quality of attention that Wang Yangming brought to his cushion.

What the body settles into is not incidental. Mulberry silk — which has accompanied Chinese domestic life for more than four thousand years — is, in the context of jingzuo, the ideal material: it asks nothing of the skin, imposes no temperature, creates no friction. Against silk, the body is free to forget that it has a surface. And a body that has forgotten its surface is a body that is very close to sleep.

The ritual is not preparation for rest. It is the beginning of rest. The self starts to dissolve long before the eyes close.

Sleep Quality: Fate, Surrender, and the Intelligence of Letting Go

Wang Defeng speaks often about mingyun — fate, or destiny — not as a counsel of passivity but as an invitation to a different kind of agency. We cannot control what happens to us, he argues. We can only control the quality of our response. And the highest quality of response, in the tradition he inhabits, is not resistance but alignment — the capacity to move with what is rather than against it.

Sleep is the nightly practice of this alignment. It is the moment when the self, which has spent the entire day asserting its preferences and managing its outcomes and resisting its vulnerabilities, is asked to stop. To yield. To trust that the body will continue its work without supervision.

For many people, this is the hardest thing they do all day.

We live in an age that has made self-optimisation into a moral virtue. We track our sleep to improve it. We analyse our rest to understand it. We deploy artificial intelligence to tell us what our bodies are doing while we are unconscious. All of this is, in Wang Defeng's terms, another form of the self refusing to yield — the controlling mind extending its reach even into the hours that were meant to be beyond its jurisdiction.

The body does not need to be optimised. It needs to be trusted. The liangzhi of the body — its innate knowing, its orientation toward health — is not improved by measurement. It is expressed through conditions: darkness, quiet, warmth, the right hour, the right surface, and the willingness of the self to finally, mercifully, get out of the way.

Wang Defeng would say that this willingness is not weakness. It is the highest form of knowledge — the knowledge that knows when to stop knowing, the self that is strong enough to dissolve.

Close the phone. Dim the light. Let the silk receive you.

The professor's midnight lesson is simple: the self that can surrender is the self that can sleep.

Carried Into Sacred Spaces

Wang Yangming wrote that the heart-mind of the sage is one with heaven and earth — that genuine stillness is not isolation but connection, a participation in something larger than the self. Every month, we journey to ancient temples and Taoist sanctuaries across China — lighting incense, offering prayers, and carrying the intentions of our members into those sacred spaces. Those who walk with us for six months or more will receive, at year's end, a curated collection of sacred tokens gathered from the altars and shrines along our path — small objects that hold the memory of incense smoke, mountain silence, and whispered prayers. Each piece travels from a place of stillness to find its way to you. Discover the Journey →🕯️🏮☯️
