Zhu Xi and Wang Yangming: Separation and Non-separation
Takahiro Mitsui's thesis: Zhu Xi's learning separates (knowledge first, action after; inner before outer; the sage outside oneself), and Wang Yangming's is non-separation (the unity of knowledge and action; the inner is the outer). The Cheng-Zhu school, he writes, still quietly reigns in the Japanese bureaucracy.
Separating thought and non-separating thought
The difference between them shows most clearly in Zhu Xi's "knowledge first, action after" against Wang Yangming's "unity of knowledge and action." This needs much insight too, but for readers here I will put it as "Zhu Xi = knowledge first, action after = separating thought" against "Wang Yangming = unity of knowledge and action = non-separating thought." The former is called "shushigaku," the latter "yomeigaku." These two schools still exert a profound influence not only on China but on Japan, so understanding both is indispensable for insight into Japan.
Learning as awakening, learning as imitation
In the glosses of the Han dynasty, learning was awakening, and to learn was understood as to wake up.
Let me unpack this. The character xiao [效] means to copy, to follow the example of. Zhu Xi interpreted learning not as waking up oneself but as "imitating the conduct of those who have awakened first."
"Loving the people" and "renewing the people"
He changed one character, nothing more. Yet that single character opened a rift that split the world in two, and it went on to shape the whole of East Asian history that followed.
The Cheng-Zhu school, in other words, is a philosophy of sequence. And because a body of thought that lays out its steps in order fits so well with legal institutions, it is always adopted by those in power. It was only natural that Ieyasu Tokugawa, who founded the Edo shogunate, seized on it, for no other philosophy was so elegant, so finished, and so well suited to governing. Even now, the Cheng-Zhu school quietly reigns as the absolute philosophy of the Japanese bureaucracy.
The act of illuminating bright virtue always shows itself as the act of loving the people, and loving the people is, in itself, the illumination of one's own bright virtue. It is not that the inner comes first and the outer after. The inner is the outer, and the outer is the inner. Inner and outer, in short, cannot be separated.
A Yangmingist theory of the city
Shin soku ri means that the mind is ri and ri is the mind. It is a thought of non-separation that takes everything as one: the mind is ki, ki is ri. From this thought of non-separation come back alleys, drinking quarters that arise by themselves, and chance meetings in plazas. Call this a Yangmingist theory of the city, different from the Zhu Xi one.
Yangming and Zen
Takahiro Mitsui's thesis (Awakening is not the goal, 2026-08-19): Wang Yangming was drawn to Zen and Daoism in his youth, reached awakening in exile, and then criticized both for staying steeped in the pleasure of their own awakening; the question is not which is better but how you stand toward the world after introspection.
Were human beings really born for that alone?
This is what I truly want to ask again. And here lies the decisive break between Wang Yangming and Buddhism and Daoism. In his youth Wang Yangming was in fact drawn to Zen and Daoism and was no great believer in Confucianism. But while banished to a remote post and living at the very limit, he suddenly reached awakening. That awakening was simple and clear.
"There is no answer outside." That was Wang Yangming's awakening.
What he criticized most thoroughly was Buddhism, Zen above all, and Daoism. Both put great weight on introspection, but both tend to stay steeped in the pleasure of their own awakening, with its energy never turning outward. Since Confucius, Confucianism had long criticized that attitude as self-absorbed and selfish.
The point is not which is good and which is bad. What we must really ask is where a daily life of endless inner exploration through introspection finally lands. Creating peace in your own heart is certainly important and precious. Most people cannot even do that much, so in itself it is wonderful. But what Wang Yangming taught was "what comes after." When you have understood yourself through introspection, how do you stand toward the world?
Dead understanding and the split of ri and ki
Takahiro Mitsui's thesis (Intellectualism and activism have no future, 2026-01-13): a world overrun by people who understand many things in the head is the mark of a world that is ending, and its root is Zhu Xi's dualism, in which ri governs ki.
To go on valuing as intellectuals those who are learned in the head, skilled in several fields, or equipped with a dictionary-like mind that can answer at once on any problem, is nothing less than a symbol of a world that is ending.
I say displacement because dualism lies at the root of his idea that "ri governs ki." At the premise of his thought Zhu Xi separated ki and ri and made a conceptual structure in which one, ri, governs the other, ki. In everything, separation was set up in opposition, and one side was always placed above the other, as better or worse, good or evil. The world began to be built, through Zhu Xi, as a "separated world."
What matters here is that Zhu Xi takes ri to exist externally.
Fukushima, and the one ground under intellectualism and activism
Takahiro Mitsui's thesis (Intellectualism and activism have no future, 2026-01-13): the Fukushima accident was the worst outcome of the arrogance of intellectualism, and activism that reacts against it stands on the same separated ground.
Why do I hold on to this problem? Because of nuclear plants.
The Fukushima Daiichi plant, which exploded on March 11, 2011, has been handled as an unforeseen accident linked to a natural disaster. It was plainly man-made, and above all it was nothing other than the worst outcome produced by the arrogance of intellectualism.
Here the separation of intellectualism and activism occurs under the dualism of ri and ki. No one notices that the separation itself is the ground, so, differing only in method, they reach action standing on the same ground.
But the action of non-intellectuals is in fact no solution to intellectualism. This is still not understood.
