The human world

Homeland City

In a lecture hall at a university, a course on logic was being held, and the desks and chairs in the class were not full, but sparse.

Lectured in the lecture hall was a young man with good features, unkempt hair, short stubble, and an old teacher's outfit that made him look at least ten years older than his face suggested.

Older youth.

However, his appearance usually does not reveal the truth, and in fact his actual age is much older than he seems.

The depth in this person's eyes can explain this very well.

And contrary to the depth of his spirit, he wore a shiny badge on his left chest, and the rectangular badge was shining with a metallic luster under the light on the top of the lecture hall, which could make people see at a glance the four Chinese characters engraved on it—'seven million'.

Underneath the Chinese characters is a lifelike avatar, which should be created through some kind of miraculous technology, creating a decent gentleman's face with benevolence, righteousness, propriety, wisdom and faith.

That is, the face of an older youth, but the badge is obviously a little more handsome than himself.

This is the protagonist of this article, and the professor of this logic class.

There is a large projection screen in front of the lecture hall, and the screen reflects a static picture, which is a very clean corridor, similar to the corridor of a high-level scientific research place that requires cleanliness and is extremely demanding, empty, white, and without people, it is not too much to describe it as dusty, and even the cleanliness of the ground is very high.

But on this clean ground, there was a headless body, wearing a set of clean overalls, the head that should have been around the neck rolled not far away, and the clean and open ground around the body were scattered, three left palms that were broken at the wrist.

The older youth pointed his whip at the projection screen and said to the students below: "Everyone, please see, this is the scene from a commission I did a month ago, this is a headless corpse, which means that this person should be dead. ”

"Hahaha," he said, causing a laugh.

He didn't care, continued to point to the screen, and said, "Look here, here, and here." ”

The older youth nodded to the location of the three severed hands around the corpse.

"These three left hands are scattered all over the corpse, but we can see that the left hand of this corpse is intact, what does this mean? This shows that none of the three left hands seem to be his. He continued.

"Hahaha." The laughter below was louder.

Speaking of this, the young man himself had a smile on his face, and said: "It should be noted that this is a course in logic, so it is necessary to use logic to reason, even if it may seem funny, and the method of elimination is the most fundamental and common method in logic. So I hope you can make an attempt, stand up and tell me what inferences can be drawn from this picture and what I said. ”

After speaking, the older young man calmly looked at the students below, waiting for them to raise their hands to answer.

This is his eleventh lecture this semester, and it is also the penultimate class, and most of the students who are still sitting in this lecture hall are students who are interested in logical reasoning or reasoning course credits, at least most of them, thinking of this, he looked at a few positions.

His words did not provoke any repercussions, and almost all the students, as if they had not heard them, seemed to be wandering away from the world and lacking interest.

Seeing the mediocre response below, the older youth had to add some chips.

"Whoever can make an inference that satisfies me, I'll give him two extra credits." With Zhizhu in his hand, he said calmly.

Sure enough, only in the next moment, almost all the dominant hands below were raised.

The main character, standing in front of the podium, looked at these extremely realistic and purposeful students with a blank face, and he didn't seem to be disgusted by this.

"Professor Dafang, are you telling the truth?" After all, for students, when they get an excellent evaluation for each elective subject at the end of the year, they can only earn 3 points, and the extra 2 credits are extremely weighty, and few people can get this kind of extra points.

After hearing this question, the protagonist who was called by the student to be Professor Dafang smiled faintly, only to see him put his hands behind his back, with a calm gaze, looked at the entire lecture hall, and stood very indifferently from the perspective of a third party, and commented "objectively": "Of course it is true, Professor Dafang, has always been very generous." ”

"Excuse me, professor, is there a limit to the number of places?" A more critical issue was raised.

The students invariably ignored the self-proclaimed statement and began to listen to the answer to this crucial question.

After hearing this, he smiled slightly: "It seems that you are all very confident, I remember that in the first class, the first thing I said was 'there is only one fact, but there can be many inferences', so whoever is closer to the truth will be more satisfied with me." ”

The students' hands were immediately raised, and it was clear that the first to get the opportunity to speak had a greater advantage.

"If I don't want credit, can I ask for something else?" Suddenly, a crisp and beautiful voice came out.

Generously looking over, a young and extremely beautiful girl stood up, with black hair, a single ponytail, no fat powder at all, vigorous, big black jewel-like eyes showing eager eyes, and she seemed to be younger than most of the students around her.

Dafang was expressionless and replied without hesitation: "No!" ”

When the girl heard this, her face was lost, she pursed her mouth and sat depressed, but the eager eyes that looked at the generous were not only not depressed, but even covered with an undisguised infatuation.

Obviously, she belongs to one of the "some".

The protagonist ignores the girl's expression and turns his head elsewhere without paying attention.

"Teacher, let me deduce." At this time, a student wearing black-rimmed glasses pushed the glasses on the bridge of his nose and stood up and said.

This person seems to have a certain prestige, and after speaking out, many people consciously put their hands down.

Dafang knows this person, his grades in various subjects are very good, almost among the best, although he is a little proud and stereotyped, but he is still a good student, and he likes good students, so he smiled and nodded: "Okay, then you say it first." ”

The man with glasses said confidently: "Teacher, this place in the picture is definitely not the place where the crime occurred, which means that this person did not die here." ”

After hearing this, Dafang asked, "Oh? How so? ”

Except for a few people, almost all of them set their eyes on the man with glasses, which did not make the man with glasses frightened, but behaved more calmly.

The man with glasses said: "From the most obvious clue alone, it shows this, that is, there is not the slightest trace of blood on the ground, and it is obviously impossible for a wound like a severed head not to bleed, so since there is no blood here, then the place where the crime occurred is definitely not here." ”

After listening to the glasses man's words, some people suddenly remembered that at the beginning, the picture made people feel a little wrong, or incongruous, especially the corpse looked, it seemed so abrupt, it turned out that the ground was too clean, clean and not even a little smudge, at this time many people nodded silently, thinking that the glasses man's good grades were justified, and people were indeed better at thinking and summarizing than themselves.

After hearing this, the black-haired girl before rolled her eyes, and didn't seem to agree with the other party's point of view.

Dafang nodded slightly after listening to the man with glasses, and said: "When we have doubts about a certain behavior, the first thing we want to know is 'why', and then we start to guess, which is the essence of logical reasoning. So what makes us 'doubt'? Is it unknown? It's fair to say, but it's not exact, and I personally like to call it 'incongruity', so it's a good habit to start with the most incongruous factors when reasoning. ”

When the man with glasses heard this, a smile appeared on his face, although praise was commonplace for him, but Professor Dafang's praise was different, because Professor Dafang himself was a different person, very different. This can be seen from the fact that in the other party's 50 years of teaching career, he has been able to cause countless complaints every year, but he has still stood and has not been affected.

What's more, almost all the complaints are unanimous, accusing him of extremely bad character and unscrupulous intentions, but never mentioning the quality of his education.

"Complaints, naturally, are all picky and say," Thinking of the man with glasses here, the smile on his face was even worse.

To the surprise of the man with glasses, Dafang immediately added two more words, which made his face stiffen.

"But."

Dafang paused, swept his eyes to the audience, and continued: "If you want to make a conclusion, one point is not enough, you must know that one-sided rationality is not necessarily all the facts, but all the facts have absolute, inevitable and complete rationality. ”

At this time, some people in the audience disagreed, and retorted: "Professor, according to what you say, some illogical behaviors, such as things done by neurosis, are all reasonable, and are they all reasonable? ”

The student's rebuttal did not make Dafang unhappy, on the contrary, he seemed to like this kind of discussion, looking at the expressions of many students below who were watching the show, Dafang smiled slightly, and said to the students who refuted him: "That's right. ”

"Why?" The questioner was clearly prepared to get to the bottom of it.

Dafang smiled: "Because, it's a nervous disease." ”

"Hahaha" The audience began to laugh.

PS: Since the "Preface" is written in the front, almost no one will read it, so I will move to the end of the first chapter.

A few years ago, when I first started writing novels, I was high-spirited, full of ambition, and boasted that I was not weaker than others.

With this empty mood, he set out to try to write a fantasy novel. However, after writing dozens of chapters, I realized that this was not what I wanted to write.

I discarded it and turned my head to think about what I wanted to write.

What to write?

It took a short time to consider this question, and for this reason, the author, who prides himself on being brilliant, has to admire his "extraordinary intelligence", and within about half a second after discovering the problem, he came up with the answer: "Write what you want to write and like to write"

What do you like to write about?

It's another problem, but fortunately the "intelligence" is still in play at the moment.

Like the Three Kingdoms.

Familiarize yourself with the Three Kingdoms.

Through his admiration for his "intelligence", he was immediately radiant and high-spirited, and he had the potential to write a book with a stroke of a pen and become a million words in one go.

However, less than halfway through it, I suddenly found that my "extraordinary intelligence" was a little unbright. The heroes in the pen always feel that something is missing, and the difference between the heroes in the pen and the heroes in their minds is getting bigger and bigger.

Put aside your pen and think about why.

Thankfully, the "Superior Talent" burned and burst into the last light, well, maybe the only time.

"It takes the accumulation of the sun and the moon"

In the face of the only legacy left by his own intelligence, he deeply believes that what has passed has passed, and what is to be started will eventually begin.

It was too late to mourn the passing of the intellect, and the author who had lost the intellect had to begin to work hard to accumulate the sun and the moon.

A year and eight months later, the book was born.

A book that has a fixed ending before the first word is written.

Along with the author's "extraordinary intelligence", there may also be "perfectionism", which is also quite thankful, otherwise there is no talent and I want to be perfect, I am afraid that this book will not be able to write a word. However, although the life of "extraordinary talents" has only shone once, after losing it, the author naturally can no longer try that kind of profound and difficult spring and snow, so that this book has to turn to the popular and ordinary.

Therefore, there may be problems in this book, such as inappropriate sentences, bullshit, and so on.

If you despise the author for this, and you are about to make incense on your cheeks and praise the author's IQ, then here I have to remind you that the author's "extraordinary intelligence" was already gone before the book was written, and it disappeared, "Whoosh! "Flew away. That's why it's completely unnecessary for you to worry about the authors with low intelligence.

But then again, people have a little bit of conceit after all, even if they are authors who have lost their talents.

After exhausting the dry intestines, the book was still stuffed with suspense and puzzles after all.

If there is anyone who wants to see the world in a second, blink to distinguish the common people, and even miss the key elements, so that they are at a loss, and they are about to have a fragrance on their teeth and cheeks, and praise the author's IQ, then I have to remind me again, please return to the introduction of this book and refer to the first sentence.

At this point, the author finally understands that the so-called works that are loved by thousands of people only need to think about it in their own minds.

The limited level and the loss of intelligence, the author, who had originally aspired to write a "novel that everyone can understand", unsurprisingly failed.

So much so that this book has become a "novel that not everyone can read".

For this reason, the author of the low level is very sorry for his low level.

Self-prologue, is the end

In the end, I want to say the most, there is one more sentence.

The author feels that the core of science fiction is not science.

Rather, humanities.
