Luo-Gin Shun was one of the Neo-Confucianism at Ming dynastic. He strongly criticized the philosophy of Wang, Yang Ming and stand with Chu-His. He divided the concept of mind and nature and thought that the Zen Buddhism and the philosophy of Wang, Yang Ming were both mistakenly taking the nature as the mind, therefore they lost the truth of the world and doing arbitrarily by their personal will. Since the nature deals with the universal principle and the mind held only on personal will. As for the universe, the principle should be recognized through the matter instead of been taking as an individual object. This is his idea that has been seen as different from Chu-Shi. But he soon propose another idea that which says the principle is identical and the matter is diverse, for dealing with the problem of the diversity of the personality and the identity of the nature. This makes his theory of principle/matter has some thing the same and some what different from Chu-His. The way8 Luo-Gin Shun doing his philosophical speculation is basically through the approach of ontology which means that for the purpose of arguing with Zen Buddhism he needs to suggest different metaphysical theory and through which to criticize some Confucian theories that are already confused themselves with the Zen Buddhism. Actually, the theory of Wang, Yang Ming is not talking about the metaphysics but the theory of practice that is why he should recognize the nature as the mind. Because one should cultivate himself by purify his mind to be unite to his nature. Anyway, Luo-Gin Shun made his contribution to recover the theory of Chu-Shi at Ming dynasty but fail to the understanding of the philosophy of Wang, Yang Ming.
