Zhao thinks that his "knowledge division of three realms" is the inheritance and development of the great philosophical thoughts of Confucius and Zhuangzi. In The Analects of Confucius, "Three people must have a teacher" and "My life is limited, but my knowledge is limited" in "Master Zhuangzi" are profound and far-reaching.
Ye Zhao absorbed nutrition from ancient Greek philosophy. More than two thousand years ago, the ancient Greek philosopher Zhi Nuo put forward the famous "Zhi Nuo's theory of knowledge circle", which vividly revealed the dialectical relationship between the known and the unknown. Zhi Nuo, an ancient Greek philosopher, was the representative of Elias and the student and heir of parmenides. Zhi Nuo is known as the "father of paradox", and he once told a story of "knowledge circle theory". The story goes like this: once, a student asked Zhi Nuo, "Teacher, your knowledge is many times more than mine, and your answer to the question is correct, but why do you always have doubts about your answer?" Zhi Nuo conveniently drew two circles, one big and one small, on the table, pointing to them and saying, "The area of the big circle is my knowledge, and the area of the small circle is your knowledge.
I have more knowledge than you. Outside these two circles, you and I don't know The circumference of a big circle is longer than that of a small circle, so I have more contact with ignorance than you. That's why I often doubt myself. In this story, Zhi Nuo compares knowledge to a circle, vividly revealing the dialectical relationship between knowledge and ignorance.
With Zhao's "knowledge division of three worlds" and the "knowledge circle theory" in contrast, the more personal knowledge, the more unknowns you know, and the more modest you are. The more people master knowledge, the more they understand human ignorance, and the more they fear the unknown world. Therefore, realizing your ignorance is the beginning of understanding, and thinking that your ignorance is great wisdom.
