Neo-Confucian Philosophy Matrix & Horak Debate Explorer (湖洛論爭)
In the 18th century, Joseon intellectuals engaged in one of the most sophisticated metaphysical debates in East Asian intellectual history: the Horak Nonjaeng (湖洛論爭). Explore the dialectic between the Capital School (Nakron, 洛論) led by Kim Chang-hyup (農巖 金昌協) and the Hoseo School (Horon, 湖論) led by Han Won-jin (南塘 韓元震), tracing how debates over animal nature and mind equanimity paved the way for late Joseon practical reform and Northern Learning (Bukhak).
The Horak Controversy & Philosophy Matrix (湖洛論爭)
Inmulseong-dong-ron (Humans and Beings Share Identical Nature)
Philosophical Argument
At the level of Original Transcendent Nature (本然之性, Bonyeon-ji-seong), the fundamental Principle (理, I) endowed by Heaven is absolutely identical between humans, animals, and plants. While physical endowments (氣質, Gijil) vary drastically, moral principle itself admits no inherent hierarchy in essence.

Inmulseong-i-ron (Humans and Beings Have Fundamentally Different Natures)
Philosophical Argument
Physical energy (氣, Gi) constrains and bounds Principle (理, I) from the very moment of materialization. Because animals and inanimate objects receive turbid and partial Gi, their fundamental nature cannot possess the five constant virtues (仁義禮智信) that uniquely define human nature.

Archival Critique & Textual Resolution
Kim Chang-hyup argued in his *Nongam-jip* that to deny the identity of Original Nature in all things is to fracture the cosmic universality of Principle (理). He maintained Yulgok's insight that Principle is all-pervading (理通), whereas Physical Energy alone is delimiting (氣局).
