Chapter 11 catch no fish

When the Internet first emerged, some old men worried: If anyone can get any knowledge, if things go on like this, there will be no fishermen in the world, so that we will have no shrimp to eat?I comforted the old man and said: No way, some people, even if they don’t go to school and don’t have the Internet, would give up fishing whenever they have the opportunity and take up farming, forestry and animal husbandry. There is no need to do anything to people who are uneasy about their profession. Hope; but others, like what Xiao Guiying sang in the play, were born and raised in a fisherman's family, from inside to outside, they are dressed like a fisherman.

People's general standpoint may be easily changed by knowledge, but the core part is difficult to touch.Suppose we originally believed that the sky was round and the earth was carried by a tortoise. Later, there was a new theory that the earth was called a planet. It is not difficult to accept this kind of knowledge. After all, no one is a relative or old friend of the tortoise, so there is no need to maintain its reputation.But if this new theory is advocated by someone I don't like, and if I am some kind of collectivist, I always think that the collective I belong to is the best in the world, and only others owe it, and it does not owe others, then I have to accept this. If you say something new, you will inevitably feel unhappy, and you will inevitably have to prove that although what you said is not wrong, it is mostly copied from me, or the local situation is special, but it is just right, etc.

The examples here are only superficial concepts, and there are deeper concepts that are entangled and consolidated behind.Often, people with less knowledge are more accommodating, while some people who have a lot of knowledge, the more new knowledge they have, the more surly they are. Having said that, I think of an old proposition. "University" talks about studying things to gain knowledge, "When you know it, you will be sincere, and then your heart will be straight." Zhu Zi explained that once you know which is good and which is not, you have to be sincere and your heart has to be straight.

Is that true?We can see that without Kant, but that's not necessarily the case.Cheng Yi, who was earlier than Zhu Zi, said, "The knowledge of virtue is not fake knowledge."He has other weird ideas, and regardless of him, this sentence alone is clearer than Zhu Zi.The closer the values ​​are to the core, the less they will be shaken by facts. This is not easy through the ages.Later Wang Xue was developed from then on—but don’t cheer, because Wang Xue still needs to penetrate the mind and matter, but in another direction, conscience is the law of heaven, and when the law of heaven is exerted, it is the principle of all things.

When this principle is taken to the extreme, it is the famous saying of Ming Confucian Liu Zongzhou: "Only with one mind, you can naturally be square and round, and flat and straight. The round is in the rules, the square is in the order, the flat is in the balance, the straight is in the rope, and the four It is the way to stand up and take the world." In layman's terms, if the mind is correct enough, physical chemistry, spaceflight, etc., when needed, will naturally flow out of the heart. Speaking of this, we will feel that Zhu Zi is more kind.Dai Zhen, a great scholar in the Qing Dynasty, was a successor to Zhu Xue.In the Qianjia era when scholars flourished, Dai Zhen was the number one scholar because of his profound knowledge. In addition to classical knowledge, he was also proficient in Western calendar calculations.

Dai Zhen's most studied mathematics work is "Pythagorean Cutting the Circle".Compared with the works of predecessors such as Mei Wending, this book is not new in mathematics. So, where did his efforts go?He transformed a set of trigonometry, using ancient and imitated words, into a native arithmetic.If Dai Zhen was not dishonest, but very dishonest, he could claim that this is an ancient book that has been buried for many years, because his apocryphal scriptures are indeed very similar. Why do such a thing?Dai Zhen believed that trigonometry was stolen from China by Westerners. He believed that Chinese Pythagorean technique contained a whole set of trigonometry, and he wanted to deduce it—with Dai Zhen’s intelligence, how could he not know his confidence and facts? Contrary, how could you not know that when you "use the Pythagorean to control the triangle", you are all copying the other party?

The relationship between knowledge and sincerity is still at a critical point. As we see today, acknowledging the facts is both the easiest and the hardest.When I read news online, I have choices. For example, if I don’t like Moonland, if I see “Moon” in the title, I just don’t open it.It is estimated that in a few years, I will believe that there is no moon in the world. It is made up by others and hung up a lamp to deceive me. Accepting the truth is a virtue, and so is standing up for your core values.Perhaps the only difference is that different values ​​contain different ways of dealing with facts.In addition, for some values, the core is deeply hidden, while for others, the core is everywhere, and actions are fatal. Therefore, the defense line is long and the mine pool is vast, which makes people feel at a loss.

In any case, no matter how wide the broadband is, it cannot pass through the suffocation of people's hearts.Take the Pythagorean Theorem as an example. You tell elementary school students that Shanggao is just a fake name, and "Zhou Bi Suan Jing" does not give a proof. It is easy for elementary school students to accept it. You put his life on the line.
