Cheng Hao, Cheng Yi
Science, also known as Taoism, is the main philosophical school produced during the Northern Song Dynasty and the Southern Song Dynasty, and its central concept is "reason", "reason" is the source of all things, and it is the most exquisite and complete theoretical system in ancient China, and its influence is deep and huge. The celestial principle of science is moral theology, and at the same time becomes the legitimacy basis for Confucian theocracy and royal power. With Confucianism as the center, Rigaku was compatible with the philosophical theories of both Buddhism and Taoism, demonstrating the rationality and eternity of the feudal Gangchang mingjiao, and the Yuan Dynasty turned Rigaku into an official philosophy. Since the Wei and Jin dynasties, Buddhism and Taoism have prevailed, Confucianism has declined, and the world has been in chaos. Although the Tang Dynasty was strong, the Confucian Taoist system believed that the Tang Dynasty was heavy with Huyi, that is to say, it was backward with ethnic minorities, and the "number of rituals" of Confucian orthodoxy was lacking. For example, Tang Gaozong and Wu Zetian, Emperor Gaozong turned his father's concubines into his own women; Tang Xuanzong and Yang Guifei made their daughters-in-law their own concubines. The "Three Principles and Five Constants" founded by Dong Zhongshu of the Western Han Dynasty were seriously weakened. The principle of respecting and inferiority of the father and son of the monarch and the elder and the young is not taken seriously, resulting in great chaos in the world.
Zhu Xi
The "five sons" of the Northern Song Dynasty: Zhou Dunyi, Shao Yong, Zhang Zai, Cheng Hao and Cheng Yi, raised the Confucian loyalty, filial piety, festival, and righteousness to the height of "Tianli", forming a complete and strict ideological system of the relationship between heaven and man, which is the science of science, because it is the development of Confucianism, so it is also called Neo-Confucianism, and the master of science is Zhu Xi of the Southern Song Dynasty. I personally believe that Rigaku is a set of ideological systems created by these people, according to the needs of the times, with the help of Confucianism, Buddhism and Taoist theory. The purpose was to serve the feudal ruling order they wanted, and the theoreticians did not want to say such things as "heavenly reason, destroy people's desires" and "starvation is small, and loss of discipline is big." Rigaku later became the most serious spiritual shackle for Chinese women, requiring women to "three from four virtues". To liberate women is to liberate our own mothers and sisters, and we should despise all people and things that favor sons over women. Theory of Science and later the Study of Mind is the most speculative theoretical system in the history of Chinese thought, and speculative nature is lacking in traditional Chinese culture. However, I have always been very disgusted with the science of science and psychology, and I think that it is a set of purposeful fallacies and heresies. Science emphasizes order, social responsibility, and integrity, which I agree with, such as Zhang Zai: Establish a heart for heaven and earth, establish a destiny for the people, continue to learn from the saints, and open up peace for all the worlds. There are rich doctrines and ideas in human history, and some of them are imprisoned by our thoughts, and we should not paint ourselves as a prison.
