Let’s take a look at the five most familiar perceptions: sight, hearing, smell, taste and touch.
These perceptions that you can no longer be familiar with have joined forces to create a full range of high-definition virtual reality world for you, showing the information passed to you by the outside world.

The former Zhuang Zhoumeng is Hu Die, and Hu Die is also vivid. I don't know Zhou Ye.
...I wonder if Zhou Zhimeng is Hu Die and? Hu Die’s dream is Zhou Yu?
——"Zhuangzi·Qiwu Lun"
Everyday life is full of various information, such as light, sound, smell, touch and so on. This information must be analyzed by the brain before it can be used by you and me. It is precisely because of the brain that we can feel and understand the world around us and react reasonably to the environment.
I have been thinking, since the brain is so important to our lives, why is it rarely mentioned in human society? Why don't people "care about" the brain very much?
After starting to study neuroscience, I suddenly realized. The human being’s “concern” that the brain lacks is not a defect. On the contrary, it is a clue that is terrifying after careful consideration—the “reality” that we all, deeply, have always believed in. Stuck inside. The "reality" that the brain shows us is too real and flawless, making it difficult to realize that, in fact, we have been trapped in it all the time.
How do you know that the red you see is red? Do you and I see the same red? Why do we assign various meanings to red? The pure color I see may not be pure, but after the brain's analysis, I can only see its pure color form. And we are just thinking and communicating in a language that can be understood by each other.
Actually, seeing is not necessarily believing. The sound you hear is only a small part of the sound; the durian smell you smell may be different from what other people smell; changing a cup can make you feel that the coffee has changed its taste; you I thought that the hemp of pepper is a kind of taste, but it is actually a kind of tremor...
Zhuang Zhou Mengdie is a philosophical argument put forward by Zhuangzi,It is believed that people cannot distinguish between reality and illusion. Two thousand years later, can we really say that we have been able to distinguish between reality and illusion?
Plato, the ancient Greek philosopher, has a very famous fable in "Utopia", called the cave. It is about a group of prisoners who have been locked up in a cave since they were young, with their necks, hands and feet tied to pillars, unable to move or turn their heads, and could only look forward to the shadows projected on the walls of the cave. Because they can only see those shadows throughout their lives, they deeply believe that these shadows are the "real world." When someone broke free from the shackles and walked out of the cave, they realized that what they had seen before was nothing but a phantom. Although this fable can be interpreted in different ways, it is really a wonderful metaphor here.
What you see, hear, smell, remember, and feel are all presented to you by your brain. When you question it, you seek the affirmation of others. You hold a flower and ask me, is it red? I answered yes. You took a breath, it turned out to be a false alarm. But you forgot, my brain is no different from yours!
You and I are actually people tied up in caves. The world that our brains present to us is the shadow on the wall.
