Dome City. It turns out that Zheng Yonghan and Xu Jingsi were still in school in Qiongcheng.
Listening to the teacher's lecture on "The Analects of Confucius". Confucius said: "Three armies can seize the commander, but one man cannot seize the will."
This sentence comes from "The Analects of Confucius: Wei Linggong". In this sentence, Confucius emphasized the importance of personal ambition and determination. He believed that a person's ambition and determination could not be captured, and that even the most powerful military could not capture a person's ambition. This sentence means that everyone has his own ambitions and pursuits, and should firmly follow his own ambitions without interference and influence from the outside world.
Xu Jingsi said: "I think I should borrow a book and read it comprehensively. Now I always only read a few sentences."
Yonghan said: "Yeah, if you only read a few sentences, it's easy to take them out of context. It feels like you can't grasp the overall situation."
Xu Jingsi said: "But do you have the time to read all the world's classics?"
Yonghan said: "Let's borrow it and read the main content."
Xu Jingsi went to the library. I read The Analects of Confucius and other Confucian works.
"Establish a mind for the heaven and earth, establish a destiny for the living people, carry forward the unique teachings of the past saints, and create peace for all generations."
The words come from Zhang Zai, whose courtesy name is Zihou, a native of Hengqu Town, Fengxiang County (now Meixian County, Shaanxi Province), a thinker, educator and one of the founders of Neo-Confucianism in the Northern Song Dynasty. He is known as Mr. Hengqu in the world, respected as Zhang Zi, and granted the title of sage.
This sentence was summarized by the contemporary philosopher Feng Youlan as the "Four Hengqu Sentences", "Establishing a heart for the world". The human heart is the heart of a benevolent person who can be born with philanthropy and charity. Scholars understand the principles of creation of all things. Make the way of heaven manifest. "Establishing a destiny for the sake of living and the people" comes from Mencius's thought of "establishing a destiny". Through self-cultivation and education, one can reach the highest state. Materially sufficient food and clothing, spiritual ethics and political education, so that the people can live and work in peace; "carry on the unique learning for the past saints" and continue the immortal teachings of the sages of the past generations; "create peace for all generations" and create a great foundation of eternal peace for all generations. The ideas conveyed by Zhang Zai allow modern people to return to the spiritual home of human beings who are straightforward and honest.
Yonghan said: "You also like to see these?"
Xu Jingsi said: "I really want to learn from the contents of hundreds of schools of thought. There are resonances in some places."
Yonghan said: "Only wise people can resonate with it."
Xu Jingsi said: "Maybe I am indeed a sage."
Cultivate oneself, manage one's family, govern the country, and bring peace to the world.
In ancient times, if you want to bring enlightenment to the world, you must first govern your country; if you want to govern your country, you must first regulate your family; if you want to regulate your family, you must first cultivate your body; if you want to cultivate your body, you must first rectify your mind; if you want to rectify your family, you must first rectify your mind. If you want to be honest with your heart, you must first be sincere in your intentions. If you want to be sincere in your intentions, you must first know things. To know things is to study things.
After observing things, one will know, and after knowing one's thoughts, one will be sincere, one's mind will be sincere, then one's heart will be upright, one's heart will be right, then one will cultivate one's body, one will cultivate one's body, and then one's family will be in order, and one's family will be in order, and then the country will be governed.
Xu Jingsi said: "What are you reading?"
Yonghan said: "The Mozi series is introduced in our textbook "Gongshu"."
In Mozi's era, predatory wars among various vassal states were frequent, seriously damaging production. Mozi hoped to relieve the suffering of the working people, which was the ideological basis for his political propositions such as "non-attack" and "universal love". At that time, Chu State was a big country, occupying a vast area around the two lakes. The Song Dynasty was located in the Shangqiu area of present-day Henan Province, but it was in a strategic location. Chu used Gongshu to make weapons and defeated several surrounding countries one after another, so he prepared to attack Song. When Mozi heard the news, he rushed from Qi to Chu to stop Chu from attacking Song. "Gongshu" is about this incident, which concretely expresses Mozi's "non-offensive" thinking.
The book advocates universal love, non-aggression, advocating virtue, advocating unity, heaven's will, Minggui, non-fate, non-joy, frugal burial, and frugal use, involving philosophy, logic, military science, engineering, mechanics, geometry, and optics. .
Xu Jingsi said: "Can you understand?"
Yonghan said: "That needs a vernacular translation. I think there are some mechanical devices. You can try it. For example, windmills and textile machines."
Xu Jingsi said, "I'll take a look after you finish it."
After walking out of the library.
Yonghan said: "There is still something to do. I want to use that energy field."
Xu Jingsi said: "Why use such a large energy field?"
"It requires a lot of energy," Yonghan said.
Xu Jingsi said: "You need to make it clear to Uncle Qi and let him guide you."
Yonghan said: "Yes. Did anyone guide you when you were doing those experiments?"
Xu Jingsi said: "No, those are plant experiments. Those are not very dangerous. There is no high-voltage electricity."
However, later varieties developed by Jingsi and others were assessed to contain certain toxins. There was almost a safety issue. I thought I had a small achievement, but it seems that more successful results are still difficult to obtain.
At night they went outside to the yard to look at the sky. It turns out that you can see the stars by looking at the constellation chart. Now it is almost invisible. Particles and pollutants in the air scatter and absorb starlight, making stars dim or completely invisible.
Feixing next to him came out with a small astronomical telescope. He stood outside, looking up at the endless starry sky. His eyes were focused and curious.
He gently adjusted the focus of the telescope with his hands, trying to magnify the details of the stars to a clearer level. He kept turning the lens barrel, looking for celestial objects that interested him.
As the telescope is adjusted, the stars gradually become brighter and clearer. He was able to see subtle differences between stars, as well as their color and brightness.
His eyes gradually adjusted to the darkness and he began to notice more details. He noticed some star clusters and nebulae, which formed beautiful and mysterious patterns.
Yonghan said: "We'll take a look later."
Feixing said: "Okay. Wait for me to mark a few stars."
Yonghan said: "Why mark it?"
Feixing said: "It's not the same as the star map."
Yonghan said: "Is the star map still wrong?"
Yonghan said: "The star map will change." The earth and other stars are constantly moving. The Earth's rotation and revolution cause the observed positions of stars to change. The stars themselves also have their own motion, which causes their position in the sky to change slightly.
Others were unimpressed.
"Many cities are affected by air pollution," Xu Jingsi said.
Feixing said: "Yes. We can only use a telescope to see it."
Yonghan said: "The Four Books, it is said that only those with life experience can understand them."
Xu Jingsi said: "I feel that I have experienced a lot."
