This is a magnifying glass lens, no wonder Zhang Zai took the comparison for a long time, saw the king come over and was startled, the king looked at it for a long time, although the mirror is simple, but the workmanship is fine, not like the objects of the Song Dynasty. He returned the lenses to Zhang Zai and asked, "Where did Uncle Zhang get this thing?" ”

Zhang Zai said that this thing was obtained by chance when he inspected the banks of the Yellow River, and he did not pay attention to it for a long time.

Zhang Zai said that he had only heard Brother Shen say some anecdotes and foreign objects before. I didn't expect to see it today.

Wang asked next to him: "Uncle Zhang can say yes, then Lord Shen Kuo." ”

Zhang Zai nodded: "Exactly, I once heard him say: The world has a transparent light, and there is an inscription on the back, where there are two crosses, the words are extremely ancient, and they cannot be read." Although the others are thin, they are not thorough. The ancients have their own"

(There are mirrors that can transmit light in the world, and there is an inscription on the back of the mirror, a total of 20 characters, and the font is very archaic, and no one can read it.) From this point of view, the ancients had their own methods when making this mirror. From "Dream Creek Pen Talk")

While speaking, the two had already walked into Zhang Zai's study, Zhang Zai picked up the two letters on the table and handed them to Wang, who saw that Bianjing and Chen Zhou came separately. Wang put the letter in his arms and was about to go back to the room to look again, and saw Zhang Zai looking at himself with the magnifying lens.

"Why does Uncle Zhang think so much about Xiao Ke?" The king asked puzzled.

Zhang Zai thought about it and said, "I always feel that you are very familiar. "Wang Bian laughed, of course you saw it in the capital last year.

Zhang Zai waved his hand, but also explained more, he said: "You have been here for a few days, I am also busy with official business, and I happened to be free today, I also received a letter from Zhang Yi of Chenzhou, which said that you have a sword. ”

Wang said: "Xiao Ke does occasionally use a sword, because the sword is angry, I originally went to the master to learn swordsmanship and get angry." The master often mentioned Uncle Zhang to Xiao Ke, and Xiao Ke had a feeling of worship. After saying this, he took out the short sword hidden in his robe and handed it to Zhang Zai with both hands.

Zhang Zai came to see the results, and then returned it to the king and said, "I don't know anything about this sword." Wang Jian was stunned for a moment, and said in his heart that the master was making a name, and then listened to Zhang Zai say: "There are many exaggerated and false legends in the world, and your master and I have often heard me talk about qi monism, and he is also a person who likes to study "easy learning", so he is a friend."

Wang was a little deflated when he listened, but since he came, it was better to humbly ask for advice, and besides, his important thing was not on the sword, so he wanted to ask Zhang Zai what qi monism was.

Zhang Zai explained: Everything in heaven and earth is composed of qi, and the dissipation state of qi is called "Taixu". Taixu is the essence of qi, and the so-called essence refers to the original form, which can also be said to be the original state of qi, from which all things arise. In the changing movement of all things, although this qi gathers and disperses, it does not increase or decrease. When qi is condensed, people can see it and call it existence; When the qi dissipates, people can't see it, and it is called emptiness.

The nature of yin and yang's movement and stillness is called Taihe and Tao. The rise and fall of Taihe, the bending and stretching of the man, is the driving force of all movements, in the final analysis, it is the opposition and sympathy of yin and yang, and the development and change of all concrete things are due to the internal opposition and sympathy, which is called "one thing and two bodies".

Wang Pan also talked to Zhang Yi as early as when he was in Chenzhou, and this way of yin and yang was also mentioned, not to mention that Wang Pan already knew that there was "Zhou Yi".

Listening to Zhang Zai's explanation, Yin and Yang remembered that his black crystal was like a Taiji Yin and Yang fish, and his interest suddenly increased in patience. He asked, "But I don't know that Uncle Zhang's 'one thing, two bodies' and "Zhou Yi"-Yi have Taiji, which is the difference between the theory of giving birth to two instruments. ”

Zhang Zaiyi was very happy, and the question raised by Wang was the key to his own theory, and he suddenly found that he had a confidant.

Since then, he has followed Fan Zhongyan's guidance, finished reading "The Mean", and then studied "Laozi", "Zhuangzi" and Taoist books, and also read Buddhist works, after research and comparison, and finally he put his scholarship on Confucian culture, based on the Confucian Six Classics.

The young Zhang Zai was not willing to limit his academic work to Confucianism, he wanted to explore, to compare, so he widely adopted the study of hundreds of schools, Zhang Zai worked hard to learn various natural sciences at that time, but determined to take his own independent academic path.

After years of study and exploration, Zhang Zai finally established his own academic path. In the second year of Jiayou, he was already around forty years old, and this year, he was admitted to the Jinshi and began to embark on the road of eunuchs.

After so many years of exploration, he finally succeeded, how he longed for someone to study with him, and even more wanted to be recognized, even if it was more communication.

Seeing that what Wang heard was the key to his academics, he was a little excited, his eyes lit up, and he said in one breath the difference between his views and Zhou Yizhi:

Zhang Zai's theory of "one thing, two bodies" clarifies the contradictory phenomenon of all things in the universe, and points out the characteristics of the unity of opposites within things. The two categories of yin and yang can encompass various categories such as void and reality, movement and stillness, gathering and dispersion, and turbidity, and they are ultimately unified in one qi. Therefore, one and two are interdependent and inseparable. One qi contains the sympathetic changes of yin and yang, so that all things in heaven and earth can be endless, in the eternal process of growth and death.

Wang Pan didn't know much about the philosophical category, but this theory was definitely superb, at least he knew that these were the basis of materialist philosophy, and his contribution to Chinese culture was indelible. He thought about what Zhang Zai said, and felt very familiar, as for the saying of qi, it seems that he has never heard of it before.

Wang Bi pondered for a long time, Zhang Zai saw him frowning and did not bother him, Wang Bi had some strange thoughts in his mind, he asked Zhang Zai: "Xiao Keke thinks so: Heaven and earth are summarized by one qi, one eliminates the other, and finally reaches a balance?" ”

Zhang Zaiyi clapped his hands and said: "Yes, the virtuous nephew knows what I said."

The king asked, "What is the explanation of the "man" that exists in the heavens and the earth? ”

Zhang Zai said: "Qiankun is the name of heaven and earth, heaven and earth are the parents of all things and people, heaven, earth, and man are mixed, in the universe, because all three are "qi" gathered into things, the nature of heaven and earth, is the nature of man, so human beings are my compatriots, all things are my friends, and all things are consistent with human nature. ”

After speaking, he pointed to the wall behind him, and Wang noticed that there were a few words written on the wall of the study: "Establish a heart for heaven and earth, establish a life for the people, continue to learn for the saints, and open peace for all generations"

Zhang Zai's county order is extremely simple in life, or there is a surplus of silver and two pennies on the ya, such as printing some brochures, or entertaining the old people in the county, and the room is arranged with simple tables, chairs and furniture. There are no celebrity calligraphy and paintings on the wall, but some poems written by him, and the main sentence is very familiar.

Wang Pan remembered that before he crossed over, Zhang Zai's four sentences were summarized by the contemporary philosopher Feng Youlan as "four sentences of Hengqu". In September 2006, when Premier *** of the State Council was interviewed by foreign reporters on the eve of his visit to Europe, he quoted this sentence to express his feelings.

When Wang saw this word, he already admired it in his heart, and he was even more surprised to see Zhang Zai say the word universe. So he said:

In this universe, there are not only people, but also objects, stars and moons, and other substances, which are stored in the air.

Zhang Zai was even more pleased when he heard it, and said that you come with me, and said that he didn't care about his own king, and pulled the king to the middle of the courtyard, pointing to the sky and saying: "You see that this vast starry sky is all between this heaven and earth, the world often says that the sun and the moon, this sun and moon are the heart of the earth, because they are in constant motion, rising and flying, and they have not stopped." ”

The king looked up at the sky, and listened to Zhang Zai's words: "The sun, the moon, and the five stars of metal, wood, water, fire, and earth each have their own slowness, slowness, speed, and speed in their movements, because they are different in nature. There is an interactive relationship between Venus, Mars and the Sun, which affects the speed of the two stars. The cause of the Earth's own movement comes from the interaction of yin and yang within it. ”

After he finished speaking, the two looked at each other at the same time, and Wang Bi also smoothed out the thoughts in his mind just now, when he pondered hard, the last two words were finally picked out in a thousand threads, seeing what Zhang Zai said, it was the universe and the earth, and his mind was thinking quickly, who was this Zhang Zai, and what he mastered was definitely not the theory of the Song Dynasty at the moment.

These two strange words were repeatedly confirmed by the king, but he was not stopped by himself and blurted out: "Aristotle, ether!" ”

Zhang Zai was first startled by what he said, and then he was confused by the words blurted out by Wang Bian, and he didn't understand it at all, but he saw Wang Bian stretching out his arms as if he was about to embrace the sky, thinking that Wang Bian was crazy.

The king is crazy, I even suspect that Zhang Zai also came through time, could it be that Aristotle got the things of the past and the present, not only about traveling through time but also through the festival, this idea is indeed too crazy, so he couldn't help but open his arms to the sky and hug the sky.

But obviously, Zhang Zai is not, he just looks at Wang Bian more and more familiar, he pulls Wang Bian's arm and diagnoses Wang's pulse. The pulse is quite stable, and I looked at Wang Bei's expression, Wang Bi was very excited, but Zhang Zai, who calmed down first, was embarrassed by this series of actions.

Zhang Zai said that today's detailed discussion with the virtuous nephew is very inspiring, and I will write it down first, and I will carefully review it in the future.

The king went back to his room to rest and looked at the two letters.

One is written by Yuan Ze, saying some things in the capital and at home, and the family is safe. There is one thing in the capital, that is, after Nong Jifeng went back, Jiaozhi was a lot more honest, especially like two monsters in the palace of the imperial court, Jiaozhi called himself "Qilin". Motozawa said they resembled buffaloes, but their bodies were covered with fleshy scales; There is a single horn at the end of the nose, which eats grass and melons and fruits; They must be hit with a stick before they can eat

Wang said to himself, this unicorn has only heard of but has never seen it, is there really such a thing? When I return to the capital in the future, I will definitely take a good look.

Looking at Chen Zhou's letter, Lu Shenyan wrote, first, the family is safe, but there is still no news under the moon; The second is that Xiao Lu felt that there were few people in the villa, so he married Rouge Tiger and also gave Rou'er as a companion at that time; The third is Master Zhang Yi's letter homework. Let him go back to Bianjing, only to do what the capital needs, only to do the first business practice.

There are joys and worries in this, Wang Bi can't sleep, and thinking of Zhang Zai's words today, he decided that tomorrow he must ask the secret of wearing ancient and modern stones.
