What is the explanation method of the underlined sentence in the second paragraph of the mysterious geyser and what does it mean?

According to the biography of Han Zhang Shizhi, Emperor Wen visited Shanglinyuan where wild animals were raised and asked about the number of wild animals in Shanglinyuan. Asked a dozen questions, the commander couldn't answer them. Emperor Wen was quite dissatisfied. Because of his incompetence, he planned to dismiss him and appoint him as the "miser" who answered irrelevant questions. After Zhang Shizhi's persuasion, the matter was forgotten.

Lin Wei couldn't answer the emperor's question. Of course, he was a "bureaucrat" and didn't do his duty. But he doesn't make false answers or brag, and there are still some merits. This reminds me of people's attitude towards things. Philosopher Ceng Yun said: "Knowing is knowing, not knowing is not knowing, knowing is also." "The Analects of Confucius for Politics" says: "A gentleman doesn't know what he knows, but what he lacks." Its basic spirit is seeking truth from facts: what you know is what you know, what you know is what you know, and what you don't know is what you don't know. Don't talk nonsense. This can be described as "knowledge".

Confucius' thought is to join the WTO, emphasizing reality and personnel. For example, he doesn't know mysterious things like ghosts and gods, so he "doesn't talk about strange things, power, chaos and gods" (Shuo Wen). He believes that in real life, we can't even handle interpersonal relationships well, how can we engage in supernatural things? Confucius paid little attention to the supernatural phenomenon and avoided talking about it, which meant that he was neither sure of its existence nor sure of its non-existence.

Great wisdom, like Confucius, still advocates that "what is known is known, and what is unknown is unknown" and keeps a tight mouth on the unknown, so people with below-average intelligence certainly can't know everything. Admitting what you know and what you don't know is an honest attitude and the smartest attitude, except those mysterious things. Only if you don't know can you know. Lv Duan and Song Taizong, ministers of the Song Dynasty, called him "not careless in small matters, not careless in big matters", which is a good example of abandoning "Xiao Zhi" as "great wisdom". Based on this, Zhang Shizhi defended Shanglin Wei in Hanshu, which was understood by Wendi.

Ding Zhaozhong, a world-famous physicist and a Chinese American who won the Nobel Prize in Physics, once said "I don't know" about many questions when he was interviewed by CCTV's "Son of the East". In the previous stage, I heard that when he gave an academic report to teachers and students of China Southern Airlines, he was "three questions and three unknowns" to his classmates: "Do you think humans can find dark matter and antimatter in space?" I don't know. "Do you think the scientific experiment you are engaged in has any economic value?" I don't know. "Can you talk about the development direction of physics in the next 20 years?" I don't know. I don't know if I ask three questions! This surprised all the students present, but soon won warm applause from the audience. Perhaps, when some people say "I don't know", they are often considered ignorant and ignorant. But Mr. Dante's "I don't know" embodies a kind of humility in life and a rigorous attitude of scientists in academic research, which can't help but make people respect.

The ancients said: "Knowing is knowing, not knowing is not knowing, but knowing." The deeper the knowledge, the heavier the unknown; The more knowledgeable, the more open-minded. As experts and scholars, we should not only honestly admit that we don't know what we don't know, but also dare to say that we don't know. Feynman, a modern American physicist, said: Scientists always have to deal with difficulties and uncertainties. When a scientist doesn't know the answer to a question, he just doesn't know; When he has a rough guess, his answer is also uncertain; Even if he is sure of his answer, he will leave room for questions. It is necessary for scientists to admit their ignorance and leave room for their conclusions to be questioned. Only by adhering to such a scientific attitude can scholars constantly "learn from things", acquire new knowledge and reach a new realm. As the saying goes, the so-called "ignorance of one thing is a shame for scholars" is intended to encourage scholars to keep seeking and making progress. "I have wisdom on zai? Ignorance is also. Someone asked me, but it was empty. I'm exhausted at both ends. " Even in the professional field, the kind of "expert" who pretends to know everything is questionable not only in knowledge but also in character.

In fact, Professor Ding Zhaozhong needn't say "I don't know". For example, you can use some technical terms to fool the past, you can say something irrelevant to prevaricate the past, and you can even euphemistically say to students, "These questions are too profound for you to explain clearly in one or two sentences." However, the Nobel Prize winner chose the most honest and frank way to answer, and his expression was natural and sincere, without affectation, mystery and "suspense". Professor Ding's frankness and ignorance not only did not damage his image as a scientist, but also highlighted his rigorous scientific attitude, which made people respect him.

Similar to Ding Zhaozhong's "three questions and three unknowns", Pavarotti's performance at a large concert suddenly stopped when he just reached the climax. The noise was so loud that the band stopped. Pavarotti frankly forgot the lyrics, please forgive me. I hope everyone will give him another chance to perform. After a silence, the audience burst into warm applause. Later, someone told Pavarotti, "You can lip-synch without admitting that you forgot the lyrics. I believe that the audience will think that the microphone is broken and will not doubt you at all. " Pavarotti smiled: "If there is a next time, I will admit my mistake. Because the truth will be known sooner or later, which will have a greater impact on my reputation.

Contrary to Mr. Ding, some people, especially individual officials, often show the style of "knowing everything" and "being knowledgeable" in the face of many problems. When the situation is unclear and things are unclear, they give instructions, make demands and make decisions, showing an attitude of "despising everyone" and "being the only one". As we all know, some instructions, demands and decisions are sometimes inconsistent with the actual situation at the grassroots level, and some even deviate from Wan Li. If the grassroots do this, the result can be imagined.

Anyone with common sense knows that people are not sages, and there are mistakes. The key to learning and the foundation of administration lies in seeking truth from facts, being earnest and diligent, and never being insincere. Don't act as a "prophet" for things you don't know, let alone think that you can "ascend to heaven" and know that once you become a leader, you will have a say in everything. This is the minimum requirement for learning, being an official and even being a man. Now some "experts" and "scholars" always like to make irresponsible remarks about things they don't know much about. The result is that "expert opinions" are not "professional", which makes people confused and unintelligible, and some "experts" are therefore weakening their influence in people's minds. In contrast, people think that Ding Zhaozhong's "three questions and three unknowns" as an academic master is of great value and warning significance to scholars. Knowing is knowing, and not knowing is not knowing. This frankness and frankness are not only due to scientists, artists and leading cadres, but also indispensable to us ordinary people.

According to Marxism, people's knowledge is obtained through direct experience and indirect experience, which has no direct relationship with the size of official positions. In fact, the reason why individual officials "know when they are promoted", "learn when they are officials" and "have great skills when they are officials" is that bureaucracy is at work. They mistakenly believe that only in this way can they show their "level", "ability" and "intelligence" and not be confused with ordinary people, which is the real "high". These officials' practice of "knowing people and being good at their duties" disgusted the people and "small things", and it was the "big things" that brought losses to the people and the country! Beware of "promoting to the foundation" and let individual officials know themselves correctly; In order to establish a realistic attitude of "knowing is knowing, not knowing is not knowing"; In order to attach importance to learning and strengthen learning, from ignorance to knowledge, from little knowledge to much knowledge; Only in this way can we constantly improve our work style, practice the "Theory of Three Represents" and make greater contributions to the people and the country. Otherwise, it is always thought that "knowing it by ascending" will block its road to promotion and progress, and eventually cause endless harm.
