The original Confucius said: "Those who are above (1) can speak (2) and (3); Below China people, you can't say it orally. " Chinese translator (1): A person with medium qualification or moral level is similar to a "sergeant". "Laozi Chapter 41": "Staff sergeant is diligent; The sergeant heard that living is death; The corporal smiled. Just laughing is not enough. "(2) language: sound" education ",telling. (3) Theory: Higher knowledge or truth. Confucius, a translator, said: "People with medium qualification or above moral level can tell them higher knowledge or truth;" "People with medium qualification or lower moral level can't tell him higher knowledge or truth." People with different analytical minds have different criteria for judging good and evil, good and bad, ignorance, right and wrong, beauty and ugliness, which often leads to unnecessary comparisons, arguments and misunderstandings. Take "China people" as an example. What criteria should be used to define them? A hundred schools of thought contend, each with its own merits, but don't forget that everything the world has done in the maze since ancient times is measured by a constant moral standard. If we use this moral standard to measure everything, everything will be simple, and there will be fewer comparisons, arguments and misunderstandings. Therefore, it is more appropriate to judge a person's accomplishment by the level of mind or moral. However, people in today's society do not necessarily attach importance to moral cultivation, and even think that the more "tricky" the better, the less likely they are to suffer losses, the less likely they are to be bullied and the smarter they are, because the standards are reversed. The level of people's mind and moral cultivation includes not only cognition, but also practice in life after knowing the truth. The result of words and deeds is to prove what you understand, and you are getting better and better, correcting your mind and subliming yourself. In this process, I may endure a lot of pain, keep my mind, give up some persistence and desire, and have some virtues myself. From the teaching principles of step by step and teaching students in accordance with their aptitude. He is above the average person, so it is not difficult to accept higher knowledge and truth. Below China people, his mind and standard of measurement have deviated too far from the right path, and the standard of measurement may be reversed. When he hears higher knowledge and truth, he is prone to disgust, argument and misunderstanding, and even negative understanding, which is not in line with the teaching principle of step by step and teaching students in accordance with their aptitude. Think about it: people with low minds suddenly understand the high truth. Isn't it too difficult to improve their minds, endure great pain and give up a lot of persistence and desire? The so-called "corporal heard this word and laughed; Just laughing is not enough. "A wise man will not know this truth.
