Yang Zheng is not in a hurry at this time, his character today is to let these Ming Heavenly Pride know that there are other theories besides Zhu Xi's science, so as to open a window for them and inject a breath of fresh air into their minds, so as to use their wisdom to discover new worlds.

After a while, Zeng Heling said, "I'm stupid, please tell us?"

Yang Zheng was very satisfied with Zeng Heling's attitude, nodded and said: "Actually, this is very simple, each trick here contains an affirmative antecedent or negative antecedent of sufficient conditional hypothetical reasoning: the reasoning of the first trick is: only if you remove the tiles on the roof, you can dry the ground in the house;

The second reasoning is that the big jar can be put into the small jar if, and only if the big jar is broken into pieces, then the big jar can be put into the small jar.

The reasoning of the third trick is: When, only when you cut off your head and weigh it, you can know whether I am right or not; if you don't cut off your head and weigh it, you can't say that what I said is not right.

These three sufficiency and conditional hypothetical reasoning helped Wang Er realize the anticipation of rectifying the "iron rooster", have doubts, and then reason according to the true face of things, as long as you have the right method, you will find that there is only one truth of the matter!"

Everyone was silent for a while, and after a while, Zhang Ben said: "The adult only relies on the interesting story of a child fighting iron roosters to make us believe in logic, is it too arbitrary?"

Yang Zheng knew that these guys were all things that had been in place for a lifetime, and he trusted Zhu Chengli from the bottom of his bones, relying on such an interesting story alone, it was indeed difficult for them to believe it, so he smiled and said, "This is easy, let's take another look?"

"Okay!" Zhang Bendao.

The field was now quiet, and everyone's eyes fell on Yang Zheng's face, listening with their ears pricked up, for fear of missing something.

Yang Zheng still said in a deep voice: "A group of Caribbean pirates, a total of fifty people, have been floating on the sea for many years, accumulating a lot of treasures, and finally one day the captain mentioned that all the pirates would share the treasures and disperse. He said that the distribution plan was as follows: all the pirates were in order, the first pirate proposed the plan, the remaining pirates voted on, if the majority agreed, the plan was followed, the pirate who did not agree to the plan was thrown into the sea, and so on, until the pirate who came in last place. The pirates, all of whom were selfish and intellectually minded, agreed to the plan and elected the captain to be the first to come up with it. “

Everyone listened and said secretly: "This Lord Yang didn't know where to get these strange questions, can such a topic be explained by Gewu, can't it be explained at all?"

Yang Zheng didn't know the dissatisfaction in the hearts of these guys, his eyes swept away, and he asked loudly: "Tell me, will these pirates agree?"

Everyone thought this interesting story was too strange, and it was the first time they had heard of logic, and they didn't have time to think about it at all, how could they know whether these pirates would agree or not.

For a while, you looked at me, I looked at you, but no one answered.

It took a long time to hear Zeng Heling sigh and say, "Please give me advice?"

Yang Zheng said: "It's very simple, the pirate captain who is in first place is in the most dangerous situation, because he may be the first guy to be thrown into the sea. However, if the captain proposes a plan and is rejected, the pirate in second place becomes the most dangerous person, because all pirates have the same intelligence, and if the captain's plan is rejected, his plan will also be rejected, even if he doesn't want a penny himself, the pirates behind him will want him to be thrown into the sea, so that the pirates behind will have more treasure. The last pirate will object to any proposal he proposes, because if the pirates in front of him are thrown into the sea, all the treasure will be his. According to this logic, the final answer was that the captain proposed a plan to take all the treasure himself, and all the pirates voted in favor of it, except for the last pirate. According to the above analysis, the second pirate was in favor of the captain because he was afraid that after the captain threw him into the sea, the next one would be his turn, and the third and fourth ...... Until the forty-ninth place has the same idea as the second place, so it will also vote for it, what do you think?"

Everyone thought about it carefully, but didn't they, but they also thought about why such a simple question, but our grid things can't be qualified?"

Zeng Heling is the champion of talent, the vision is very high, and he is also proud of his talent on weekdays, since Yang Zheng came to the Hanlin Academy, he met his opponent, at first he was always dissatisfied, but after defeating, after careful thinking, Yang Zheng also learned a lot of things, at this time after thinking about it, I feel that although this logic has the shadow of Zhu Cheng's science, but it is more about paying attention to observation, Analysis and reasoning, the problem of interesting things on both sides just now is not a difficult matter, but it is the use of assumptions and reasoning to get the original result of the matter, understanding this, he vaguely feels that this knowledge is not as simple as the surface, if it can be mastered, it does have great benefits, as Yang Zheng said, through perception, to see the essence of things clearly, this is more practical than Zhu Cheng's physical character, and more pragmatic!"

"Dare to ask adults, how to learn this logic?" Zeng Heling asked seriously.

Hearing this, Yang Zheng breathed a sigh of relief, and said: "Logic is quite similar to what you have learned, according to your solid foundation, it is not difficult to learn logic well, because logic is all around us, as long as you carefully seek the truth, to observe, and then use the principles of logic, together to solve it!"

Everyone was confused, only to hear Zeng Heling say: "Ask the adults for advice"!

Zeng Heling is the champion, known as majestic in the eyes of everyone, seeing him like this, everyone also hugged their fists and said: "Ask for advice!"

Yang Zheng said in his heart: "I'm still afraid that you won't learn?"

"Well, well, the so-called logic is the understanding of a syllogism, in which one can think about particular knowledge with the help of universal knowledge; In terms of the two different aspects of general knowledge and special knowledge, a person may both know and not know things that belong to the same category series. Although the universal premise of the syllogism already contains special conclusions, through the inference of the words in guò, people grasp the connection between the universal and the particular, discover the cause and the basis, and gain new knowledge in the conclusion. ”

This unheard of and unseen knowledge surprised everyone, but also full of curiosity.

Yang Zheng secretly breathed a sigh of relief, and said in his heart: "It seems that the effect is very good!" After a pause, he continued: "Any research and learning knowledge always has something known in one sense, and in another sense, it is to obtain unknown knowledge. Logical truth, therefore, is of considerable value, because its conception of truth is objective, it has both an empirical basis and at the same time it is independent of experience, it is an objective truth that depends on kilometers, rules of reasoning, and theorems, and the essence of this truth is also universal necessity, and it reveals the universal nature of things. Therefore, the more important significance of the concept of logical truth lies in the fact that it opens up a new way for us to know the truth that is different from epistemology, that is, we can also obtain the truth understanding of the unknown realm through logic. If you have the heart, think about it today, and in a few days, how about the Japanese officials sort out the books and then give a lecture?"

"Good!"

Although everyone doesn't understand how much better this logic is than Zhu Cheng's science, one thing is certain, that is, what the head of the court named Yang Zheng said in front of him must be correct, he said that logic is useful, then it must be useful, he will learn it!

Yang Zheng didn't expect that he would cut into it so smoothly, and after thinking about it carefully, he felt that it could be so smooth, in the final analysis, it was the charm of Aristotle's logic, Aristotle, as an encyclopedic scientist, who made contributions to almost every discipline. His writings cover ethics, metaphysics, psychology, economics, theology, politics, rhetoric, natural sciences, pedagogy, poetry, customs, and Athenian law. Aristotle's writings constructed the first extensive system of Western philosophy, encompassing morality, aesthetics, logic and science, politics, and metaphysics. He is a pioneer in many disciplines. Unlike Plato, he was a systematizer of disciplines, and many later philosophical and scientific systems were established based on his system. It was edited in the first century AD by Andronicus of the Aristotelian school. The book collects six works of Aristotle's logic: Categories, Interpretations, Pre-Analysis, Post-Analysis, Arguments, and Arguments. It mainly discusses propositions, categories, syllogisms, etc., and expounds the methods of proof, definition, deduction, etc. The Instrumental Theory deals primarily with the deductive method, which laid the foundations for formal logic and had a great influence on the development of this science.
