Hey
What a question!
The pre-Qin scholars were the most brilliant period in Chinese philosophy and thought. For more than two thousand years after that, we are just eating the leftovers of these ancestors.
For your question, you must first blame Qin Shihuang. He burned books and harassed Confucians, which led to the destruction of a large number of pre-Qin books. Since then, the Confucian-only approach of Zhu Xi and others has further caused the pre-Qin thoughts to be selectively forgotten, which directly led to the fact that few scholars later knew about it and could not learn it.
In modern times, there have been movements such as destroying the Four Olds and so on. We are stupid and have destroyed very few of the treasures of our ancestors, leaving all kinds of ideological and academic (including philosophical) problems. In the cultural field, what is left is really poor. At this time, Western culture entered China in large quantities, so that most of the current philosophers only know: Descartes, Spinosa, Leibniz, Locke, Rousseau, Schopenhauer, etc. Coupled with the advanced science and technology in the West and the rich material life, people's instinctive desire is to integrate with the West.
Another problem is that nowadays people’s ancient Chinese is generally very poor. It is very difficult to understand the books of the pre-Qin scholars. Over time, between eating and academics, of course, people tend to gravitate towards the West. .
It is your great wisdom to be able to recognize the brilliance of the pre-Qin scholars. Study and study it carefully. Maybe you came to this world with the mission of restoring Chinese philosophy.
