Throughout the ages, people have always preached the word "seeing is believing". But is the fact really what people see with their eyes? People's eyes can only see the image reflected on the surface of the material in the brain, and can only reflect the objectivity of the material, so what they see is not necessarily the truth.

Confucius, a generation of famous teachers, was once trapped between Chen and Cai with several disciples. He hasn't tasted white rice for seven days, and he's starving. Therefore, everyone is exhausted, lying down and resting during the day, and has no strength to move or feed.

Later, Yan Hui tried to get some rice from someone else's house to cook.

When the meal was about to be cooked, Confucius passed by the kitchen and saw disciple Yan Hui holding the rice in the pot with his own hands. Confucius thought for a moment and pretended not to see it. Yan Hui came in to invite Confucius to dinner. Confucius got up and said naturally, "I dreamed of my ancestors, so I should sacrifice these clean foods to them first."

Yan Hui quickly replied: "No! Teacher: Just now, I saw dust falling from the rice in the pot, so I grabbed it out, but it was not easy to throw it away, so I ate it myself.

Confucius sighed and reflected: "I thought seeing is believing, who knows what I actually saw may not be credible;" Finally, it is not necessarily reliable to measure things with your own inner thoughts.

It seems that it is really not easy to understand a person's personality through some things! "

Then there is the magic show that people like to see and hear in today's society. Magicians deceive people's eyes again and again with all kinds of clever tricks and clever props. On the gorgeous stage, the beautiful actress winked and smiled at the audience. Then the magician covered the actress's head with an iron box. In the next second, with tens of thousands of spectators watching, the magician removed the tin box and the actress's head from her neck. No audience. Not stunned by this strange sight. Even more amazing is that the actress's head is still smiling at the audience. Actresses will naturally not be "dismembered". This is magic, which brings people visual illusions and feelings. The magician deceived people's eyes and human body.

Only after Confucius knew the specific situation did he know that his disciples were misunderstood and deceived by glasses, so he understood that "seeing is believing." Magicians use scientific laws such as physics and biology to create extraordinary magic and bring people visual enjoyment and spiritual pleasure. Therefore, glasses are not trustworthy.

To sum up, seeing is not necessarily believing. If you completely believe that the present phenomenon is superficial but don't think deeply, you will become confused and can't recognize the essence of things. It can be inferred from this that only when you experience things with the truest heart can you get the truth and facts, because what you see is not necessarily true.

The second article is very long, so you can cut some of it.

As the saying goes, "hearing is false, seeing is true", which is not only the experience of hundreds of thousands of years, but also many people regard what they have seen with their own eyes as truth.

In our daily life, we often hear people say that what I saw with my own eyes can never be wrong.

So, what the eyes see must be the truth? In fact, absolute objectivity does not exist, and everyone's view of things is inevitably subjective, that is, cognitive "blind spots", so even what we see with our own eyes will be more or less limited by subjective thinking, and there are certain cognitive misunderstandings and deviations.

From ancient times to the present, there are countless examples of cognitive deviation caused by the limitation of subjective thinking, which leads to embarrassment:

The embarrassment of "seeing is believing"

Legend has it that there was a loving couple in ancient times. The husband goes out to do business and the wife waits at home.

A few months later, the husband missed his wife very much and went home to visit him, but he saw a scene that made him very sad-he missed his wife very much and was eating with a strange man. She smiled and stuffed a piece of food into the man's mouth, feeling very close.

He immediately thought that his wife had betrayed him and would not take another step.

He turned and left in a rage and never came back for a long time.

When he was white-haired, he thought that his time was running out and wanted to untie the knot while he was alive, so he returned to his home that year.

I saw that his wife had white hair, but she lived alone.

His wife told him frankly that the man was her long-lost brother and just happened to visit her here.

When Yan Hui, a student of Confucius, was cooking porridge, he found something dirty falling into the pot.

He quickly scooped it up with a spoon and was about to dump it. Suddenly, he thought that a porridge and a meal were hard to come by, so he ate it.

Unfortunately, Confucius walked into the kitchen at this moment, thinking that Yan Hui was stealing vegetables, and gave him a good lesson.

After explanation, Confucius suddenly realized that what he saw was not "the truth of the matter".

Confucius later said with emotion, "What I saw with my own eyes is not true, let alone hearsay?"

Examples like "seeing is believing" are also common in modern society.

On the stage of the Spring Festival Evening, Liu Qian puzzled more than one billion people.

"I can't believe my eyes!" I believe not only Dong Qing shouted like this, but also many people are watching TV to "witness the miracle".

So, why don't you see the objective facts with your own eyes?

Visual deviation

Although most of the time we can see the relatively real situation, occasionally there will be deviations, which is what we usually call "illusion."

The illusion comes from both physical and psychological aspects.

In other words, the sensory and physiological structure of the human body, as well as our usual cognition of life, will affect the brain's judgment of vision.

Many illusions, even philosophers, are often confused by superficial phenomena without careful rational speculation.

Aristotle once thought that heavy objects fell faster than light objects, but later Galileo's leaning tower experiment proved him wrong.

From a psychological point of view, psychological illusions based on human physiological characteristics include: blind spots, visual persistence, color illusions, illusions caused by brightness, illusions caused by psychological cognition and so on.

1. Blind spot.

When people look at things, their eyes observe the image of the object by sensing light, and then report it to the brain, and then the brain will issue corresponding action instructions.

However, the eyes will sometimes fail: when the projection of an object on the retina is just in the position of the blind spot of the retina, we can't see.

But fortunately, there are two eyes on our face, and their blind spots do not coincide, so even if the object is in the blind spot, the other eye can still see it, and the eyes can complement each other.

But when you use only one eye, you may turn a blind eye.

2. Visual persistence.

In addition to blind spots, eyes also have a feature of short-term visual persistence, which is what we usually call "afterimage".

The afterimage will give us some illusions. When the speed is high enough, the afterimage will be coherent. For example, when we watch a movie, we don't think of "what I see is a frame-by-frame separated picture, and there is an instant change of light and shadow between each frame".

Many people have played homemade animation when they were young, that is, drawing a continuous action villain on the corner of each page of the book, and then turning the page quickly, you can get a "moving" picture, which is a typical physiological visual error.

3. Color illusion.

The outside world is conducted by light and enters the eyes to form what we see.

White light is composed of colored light with different wavelengths. If two colors can be added together to become white light, then they are complementary colors.

When the cells on the retina are irradiated by a lot of light of a certain color, the other cells that are not irradiated by * * * will start to move, and the corresponding complementary color will fill in the "gap".

Therefore, in the dark blue night sky, the white moon looks yellow.

Psychological prejudice

People's consciousness is not a blank sheet of paper, which contains their own life experience, knowledge background, creative ability, subjective feelings and other "preconceptions."

Prejudice may cause the illusion of psychological cognition.

So apart from visual deviation and psychological prejudice, what you see will have color, the original theory will permeate scientific observation, emotions will affect judgment, and what you see with your own eyes will deviate from the facts, which is not difficult to understand.

Not only in daily life, people can't get rid of the influence of "foresight", even in scientific research.

Science differs from common sense.

The "unreality" of "seeing" in common sense can sometimes be eliminated in science.

However, this does not mean that there is no such thing as "not seeing the truth" in science.

In the history of optics, in the observation of photoelectric effect, the particle school "sees" that light is a particle; On the contrary, the wave school "saw" that light is a wave in the observation of interference and diffraction of light.

In fact, light itself has "wave-particle duality", and both particle school and wave school contain one-sided truth and have their own limitations.

Of course, it is undeniable that the eyes are the most direct and can best reflect the original appearance of things among human sensory organs.

This has been confirmed by Thomas, a scientist at Vanderbilt University in the United States. James and his colleagues confirmed this through two experiments.

Thomas's experiment not only proved that "seeing is believing", but also proved that "seeing is not necessarily believing".

Because the human eye can only see the superficial phenomenon of the material world, the information it captures is not necessarily correct.

Other human senses also have their limitations. Even the information filtered by the brain may be influenced by subjective thinking in many cases, and the conclusions made may not be accurate.

The world is hindered by the concept of real society, and often thinks that what is seen through one's own eyes is true, and what is not observed through one's eyes is completely untrustworthy. In fact, people's vision can only see part of the material world, and most of the time what they see is illusion.

We now know that these reasons can cause people to have optical illusions, which can be used as the basis for correcting cognitive errors, but there is no need to rush to correct them.

People use these small illusions to do many positive things, such as cartoons, simulation devices for training drivers and so on.

So don't believe what you see or doubt everything you see just because you know this occasional mistake.

So, how can we grasp the reality we see? This needs to eliminate the background that causes illusions and preconceived prejudices.

When paying attention to things, don't be limited by your own prejudices, don't rush to conclusions, think more, be more rational and less reckless, and many "misunderstandings" can be eliminated.

We don't know how many times we have heard the word "seeing is believing" or how long it has been circulating. Is this sentence still a classic for today's society? I believe the answer lies in your heart and mine. Don't trust your eyes in everything, and don't trust your ears in everything.

The third article

Seeing is not necessarily believing.

-reading The Journey to the West.

The Journey to the West is one of China's classical masterpieces, and I was deeply impressed by the tortuous plot and the bizarre experience of Tang Priest.

Wu Cheng'en, the author, tells us the story of Tang Priest's master and apprentice who went through difficulties and obstacles, all the way down to the devil, and experienced eighty-one rare scriptures.

It is this tortuous story that won the hearts of readers.

Among them, Monkey King Thrice Defeats the Skeleton Demon is my favorite.

The story tells that Bai lived forever in order to eat the meat of Tang Priest, and deliberately disguised himself as * * *, grandma and grandpa to deceive Tang Priest.

The Monkey King was crucial, and he saw the true face of Bai in time, while Tang Priest only looked at the surface and was confused by the hypocrisy of Bai. Instead, he blamed his apprentice for being rude, and as a result, he was taken away for nothing and almost died.

Come to think of it, there are many such things in our lives.

After school, I walked at a brisk pace on my way home.

Suddenly, there was a sad cry in the distance: "save me this unfortunate person!" " Please have pity on me! ..... "I looked inside and saw a middle-aged man in rags and unkempt appearance crawling on his knees, and a large group of people were saving money in his bowl.

I couldn't help reaching into my pocket and putting the only 1 yuan coin into his bowl.

Later, he put the money into a cloth bag, and his face showed an imperceptible sly smile, which made my heart do it one brace up.

The crowd gradually dispersed, and a strong curiosity made me follow him.

I saw him struggling to climb to the end of an empty lane, suddenly jumped up, took off his rags, and suddenly a young man in a suit and tie appeared, proudly counting money.

This is a trivial matter. Some people deliberately cheat you for money and then murder you for money, and it's too late to regret it.

We should learn to distinguish good from evil like the Monkey King, because in today's society, some people are hypocritical on the surface and dark on the inside, so we should always keep our eyes open and know that "it is essential to prevent others from harming others"!
