The claim
The Four Beginnings — the moral feelings Mencius identified — issue from principle. The Seven Emotions issue from material force. They have different origins and must not be collapsed into one.
What it held
The Four-Seven debate is the central controversy of Korean Neo-Confucianism and one of the most technically sustained arguments in East Asian philosophy. It began as a correspondence between Yi Hwang, known as Toegye, and the much younger Gi Daeseung, and ran for eight years.
The question is where moral feeling comes from. Mencius listed four beginnings — compassion, shame, deference, right and wrong — and the tradition also recognised seven ordinary emotions. Zhu Xi's framework has principle as pattern and material force as what moves, which suggests all feelings issue from material force.
Toegye refused that. If the moral feelings have the same source as appetite and anger, morality has no distinct foundation. So he argued that principle itself issues — that li is active, not merely a pattern that qi instantiates.
This is a genuine departure from Zhu Xi, and it was made on ethical grounds. Gi Daeseung's counter-argument, that principle cannot act, is the orthodox position and is philosophically cleaner; Toegye's is more responsive to what moral experience is like.
The correspondence is a model of how to disagree: neither man conceded, both revised, and both published the exchange.
How it argued
Extended philosophical correspondence, conducted courteously over years, with each side revising in response to the other.
What it was arguing against
The reading of Zhu Xi on which principle is inert and everything active is material force.
Where it disagreed with itself
The Four-Seven debate itself, which the Yulgok school continued from the opposite side and which has never been settled.
Common misconceptions
That Korean Neo-Confucianism is derivative of the Chinese. The Four-Seven debate has no Chinese equivalent, and it addresses a real gap in Zhu Xi's system.
How it began
A letter from a young scholar questioning a diagram Toegye had drawn, and a senior figure who took the objection seriously enough to argue for eight years.
What became of it
Living, as a scholarly tradition. Toegye is on the thousand-won note and the debate is still taught.
Lasting influence
Korean intellectual life for four centuries. Japanese Confucians read Toegye closely, and he was more influential in Tokugawa Japan than most Japanese thinkers.
Why it still matters
The question of whether moral motivation has a different source from ordinary desire is a live one in moral psychology, and this is a sustained treatment of it.
Put another way
Two springs feeding one stream, and an argument about whether the water can be told apart.
Where to start
The Ten Diagrams. It was written to be a summary and it works as one.
The surprising bit
The debate was conducted entirely by letter between a man in his late fifties and one in his early thirties, and the junior party's objections forced the senior to revise his position three times.
In their own words
The Four Beginnings are the issuance of principle, the Seven Emotions the issuance of material force.
Where principle is, material force follows.

The verdict
The most technically demanding argument in Korean philosophy, conducted with a courtesy that is itself instructive.
