The boundaries of the world and the criteria for all revitalization in the twenty-first century seem to depend entirely on technology. I have often wondered what use the existence of the humanities and the arts is to mankind outside of academic research.

I usually feel a sense of powerlessness when trying to explain the existence of the humanities and arts in terms of the humanities and arts themselves: it all seems to be like a kind of excuse that we all know by heart. Reading Plato's Ideal State, I suddenly felt the existence of a similar topic.

In the seventh book of the Ideal State, Plato puts forward an idea about the "cave". He believes that there is a group of people who have been living in a cave, and they are chained to their bodies from birth, without personal freedom, without access to the outside world, and confined to a confined space. Because there is no way out, they take what they see in front of their eyes as the real thing. When one day a prisoner breaks free from his chains and discovers the outside world, he does not want to go back to the cave and continue to live like a prisoner, and he is ready to rescue the people in the cave, but no one believes what he says, and in the end, he is killed by the prisoners instead. In this story, the cave represents human society.

The core content of Plato's cave theory is a rational analysis and judgment of objective reality, which has a certain objectivity. The cognitive method and standard established on this scientific and rational basis are what we usually call a scientific method in the sense. Therefore, we must learn to think and treat problems dialectically, so that we can have our own set of a thinking systems. In this process, we will also gradually form a set of philosophical ways and methods of thinking that are more in line with the objective reality, more objective, scientific, rational, and objective criteria, to realize the improvement of ourselves in the cognition of thought, and finally obtain continuous progress in our understanding of objective reality.

The cave theory is a logical abstraction of the cave made by Plato. Since Plato believed that the world has a structure, people always enter and exit this structure in some way, and this way is often more hidden and imperceptible than the actual situation. Thus, the world that humans know is a structure of various "holes", and the "caves" that humans enter and exit become the basis of our perception of the world's reality. Plato believed that if people have a correct and objective understanding of the world they know, they will achieve a better quality of life. He believed that people could see and experience a more real and better world from such a cave, rather than a false, unreal, and uncertain world.
I think the existence of the humanities is to help human beings recognize, perceive and transmit the larger world.

Human beings spend their entire lives coming out of the cave: "Man is originally ignorant, like living in a dark cave, can only see his own shadow reflected on the wall, only when human beings turn their backs can they see that the shadow comes from the light that does not belong to the cave, and only then can they understand that the world in which they originally lived is only a cave, and the things they originally thought were real are only shadows. "

Every stage of life is not a cave, or perhaps the whole world and the system of perception and basic knowledge built by human beings is a cave, where we are so tightly trapped by something in our necks and arms and legs, that we can only see the shadow on the small wall on one side of our eyes, and think that shadow is real. In Plato's allegory, when someone escapes the cave and goes outside, he is mesmerized by the dazzling light of the sun, and at first is unable to adapt. However, over time, he begins to adjust to this new world seeing things that are more real and beautiful. He realized that those shadows inside the cave were only a small part of the world, and that the real thing was more perfect and truthful. And in the real world, one day when we suddenly realize that that shadow is false, will it be pain, anger, or, bravery to come out of the cave?

If the cave is enlarged infinitely, is the world, the earth and the universe all caves, and how should we look at alien civilizations and ourselves? In the film's cosmic editorial section, the protagonist asks the ultimate question: "What is the meaning of human existence, really?”. Then, with humanity's doubts, he transforms into a flock of brown birds and flies towards the light of the Supreme Being beyond the cave, amidst poetry and music.

This section of the movie creates an almost manic atmosphere is an imagining of the state of man infinitely close to the idea. Inquiry into the humanities is the closest we can get to the truth. Whether it is an extraterrestrial civilization or a deity, if we are fortunate enough to be unshackled and come to the mouth of the cave under the revelation of some unknown power, can we really just get rid of our fragile flesh and fly lightly towards the sun, which is the truest and the best? To what extent can human beings bear the truth of the world?

Is it true that most of us, even if we try our best, cannot get out of the cave to look directly at the sun, and can't really reach the answer. At best, we can glimpse a glimmer of truth at the mouth of the cave, and then, like the protagonist of the movie, remain in the worldly cave with curiosity and awe of the unknown.
