Shen Yu continued to eat unhurriedly, the "thunder" rumbled outside, and the noise was annoying, so I stood up, closed the window, and closed the curtains.

"You just don't dare to face the reality with this action." She pointed her chin at me and said, "But it's the right thing to do." Because I'm going to talk about a philosophical question right away.

"This question was first posed by Pythagoras, the old man who proved the Pythagorean theorem in ancient Greece, and the ultimate question he asked was, 'Who am I, where am I?' - now I ask you, who are you and where are you?"

"I'm Yan Zhu, I eat hot pot at home." I replied earnestly.

"Okay, then may I ask, is your answer the true nature of the facts?"

I slapped the table, and it clanged. I pointed to the hot pot and said to her, "Listen to this noise, this is not a dream, my hands are red—we are both sitting at the table, and you stretch your hand to the hot pot, don't you feel hot?" ”

"No, what we see, hear, feel, and know is actually verifiable experimental science, but this is not necessarily the whole truth. The philosophical 'who I am and where I am' goes beyond experimentalism and is closer to the origin of truth. There is a well-known macro hypothesis about this issue, which is the 'brain in a vat'. ”

I was stunned: "I know this hypothesis." ”

"Stay silent first if you know, the teacher will give a lecture, and the children will not interject." She gave me a blank look.

- yes, let's not interrupt her role-playing for now. In order to cooperate with her "performance", I also went to the bookcase to find a notebook, pretending to be taking notes seriously, listening while eating, listening and writing.

"The proponent of 'Brain in a Vat' is Hilary Putnam, an old gentleman who is a philosopher of science. The hypothesis of a brain in a vat is very simple - since experimental science has found that all human feelings and judgments come from the brain, how can we prove that our human body is not a brain soaked in a nutrient solution? Our appearance, limbs, study, work, and even family, relatives and friends are actually personalized scenes created by the brain? ”

I was so shocked that I forgot to pick up the dish, and I bit down on the chopsticks, and my teeth hurt.

- Is this pain also made by the "brain in a vat"?!

Shen Yu looked at me and sneered.

"Don't be afraid, I'm just giving you an example, it's not like we're two ugly brains. In fact, this illusion is not much obscure, and some movies have long used this stalk.

"Similar to this, there is another example, and that is the sheep barn paradox. It is said that there is a flock of sheep on the farm, and they are all kept in the sheep house, and the farmer has set up an automatic feeding machine, which will start regularly at 8 am, 1 pm and 6 pm every day to feed food from the feed port on the roof of the shed.

"There is a clever fellow in the sheep, who often observes, verifies it repeatedly, and sums up a theorem, that is, from sunrise to sunset, there are three times a day when food comes. After a long period of observation, the sheep felt that the smart sheep had summed up a truth. They saw the wise sheep as the 'holy sheep', and the wise sheep had their own followers and students.

Soon one of the students, the sheep, on the basis of the teacher, refined this rule, and found that from sunrise onwards, food would come every five hours, and so on three times until sunset.

These two theorems make the sheep completely reassured. They all live a peaceful and lazy life, and they don't have to worry about it anyway, just wait for the sun to come out, and then the food for three meals a day will come.

"It is conceivable that although these two theorems can be repeatedly verified in sheep birth, one day, what they are waiting for is not fragrant food, but cold butcher knives."

When she said this, I had just put a piece of hand-cut mutton in my mouth, and I don't know why, but this delicious mutton didn't taste good no matter how I chewed it.

"The death of a sheep is sad, do you feel the same way?" Shen Yu asked me through the hot air.

"I've been talking about it for so long, and I understand what you mean. You're saying we're all lambs to the slaughter, and the asuras are here to harvest us, right? ”

"I didn't say that." Shen Yu shrugged, "Let's take the sheep house as an example." If one day, the automatic feed machine breaks down, and the sheep wait for more than two hours, dizzy with hunger, but there is still no fodder in the 'air' (the roof of the sheep shed).

But just when they thought the end was coming and were in a state of confusion, the farmer opened the roof and threw the hay into the sheep barn by hand. Then the sheep were shocked again - there was some kind of life that cared for and loved them!

"In the case of the failure of the 'objective law', this kind of life tore a hole in the sky, and then gave food to the sheep, so that the sheep world returned to tranquility and beauty. They praised the farmer, and although the farmer had long since closed the roof and walked away, the sheep still thanked him and revered him.

"Then another 'theological sheep' appeared in the flock, and he gave the farmer a name and called him 'God.' Although the farmer later repaired the automatic feed machine and still feeds him at a fixed time every day, and he never appears on the roof of the shed again, the believers of the 'theological sheep' still regard him as a god and worship him in legend.

"And the 'theological sheep' also discovered the 'law' by claiming that it was kneeling on the ground before the 'gods' came, and that there were two other sheep on its left and right, lying and standing.

"The 'theological sheep' secretly recorded this in its heart, and it thought that it was a ritual to be able to see the gods again - three sheep lined up in a straight line, lying on the left and standing on the right, and the one in the middle was the 'priest', and it knelt on the ground, raised its head and kept praying for the blessing of the gods, so that the gods would surely come again and save the world......"

I gasped.

The water in the hot pot evaporated too much, Shen Yu walked into the kitchen and brought a bottle of pure water to refill.

"I understand what you mean, whether it is the brain in the jar or the sheep in the house, they are actually framed within a limited field of vision, and the laws they summarize are actually things in this small world - what you mean is for us to break the limitations and look down on the current things from a larger perspective, right?"

"That's right, because whether it's a flock of sheep or a farmer raising sheep, there is something in common between the two. What we have to do is to open our eyes to the world and find what humans and asuras have in common, because that's what we can understand......"

"Then, we can study these similarities and find a way to restrain the Asura?" I said excitedly.

"That's right," Shen Yu smiled, "At this point, this is the methodology we can rely on." ”
