■ Interpretation

This old saying talks about the different progressive stages of learning. From being erudite to practicing sincerely, only then can we have something to rely on, succeed in what we learn, and use what we learn. Comrade *** quoted this sentence to raise issues of thinking, learning and practice. He believes that these three should complement each other, and knowledge and action should be integrated. "Knowledge" is the foundation and premise, and "action" is the focus and key. "Knowledge" must be used to promote "action", and "action" must be used to promote "knowledge" to achieve the unity of knowledge and action. If the knowledge learned cannot be combined with self-discipline and self-cultivation, combined with development practice, and combined with solving problems, then the so-called learning may go astray and it will be difficult to learn to cultivate morality, learn to cultivate one's morality, and learn to learn. It is difficult to achieve the real purpose of learning by starting a business. Comrade *** proposed that the purpose of learning is all about application, and we must make good use of the "target" of Marxism to shoot the "target" of the Chinese revolution; Comrade *** proposed that learning Marxism-Leninism must be precise and effective. A learning party is not academic or book-based, but practical. It is necessary not only to study, but also to reflect the results of learning in work. Only in this way can we truly learn, live and learn well.

■Original Classic

Learn it well, examine it, think carefully, discern it clearly, and practice it diligently. If there is no learning, it is impossible to learn; if there is no questioning, it is impossible to know; there is no thinking, and if you think about it, you cannot learn; there is no discerning, and if you discern, it is unclear; there is no understanding Go, go and do it with great care and ease. If a person can do it once, he can do it by a hundred; if a person can do it by ten, he can do it by a thousand. If you can do this, you will be wise even if you are stupid, and you will be strong even if you are soft.

"Practice it sincerely" is a famous sentence about scholarship in Chapter 20 of "The Doctrine of the Mean". The five "zhi" characters in the sentence all refer to learning objects-all kinds of knowledge. It means learning all kinds of knowledge extensively, asking others in detail, thinking carefully, clearly distinguishing right from wrong, and practicing it in a down-to-earth manner.

This passage divides learning into five closely connected links, or five progressive stages. "Erudition" emphasizes that learning must first involve a wide range of knowledge, so as to "accommodate all rivers, and tolerance is great." "Interrogation" is the second stage, "trial" means detailed and thorough. That is to inquire into the knowledge in detail, get to the bottom of it, and truly understand it. After that, it must be digested through serious and careful thinking. This is "careful thinking". "Clear discernment" is the fourth stage. It is necessary to distinguish the knowledge learned, discard the rough and select the essential, discard the false and retain the true; otherwise, the so-called "erudite knowledge" will be mixed, and the true and false will not be distinguished. "Du Xing" is the final stage. "Du" means being down-to-earth, single-minded and persevering. We must apply what we have learned and achieve "unity of knowledge and action." "The Doctrine of the Mean" tells us that if we can study in this step-by-step manner, then "even if we are stupid, we will be wise, and although we are soft, we will be strong."
