Arrogance is a plague of people in the "aristocratic class" and is easily infected. Once infected, it is difficult to cure. Prejudice is a reflection of people's subjective thinking consciousness, which is accompanied by human society. This is more terrible than arrogance. Throughout thousands of years of human history, arrogance and prejudice have always plagued mankind. Arrogant people are more or less influenced by family background and living environment, which makes them feel like "aristocrats" and other upper-class people, and disdain to talk and have fun with "little people". This disease has its historical roots. Thousands of years of feudal tradition divided people into different classes. This hierarchy has produced a germ, which is now commonly known as "arrogance." Most people who suffer from this disease are those who grew up in the infancy of "power" and "money". Beggars are hard to be infected because it goes against their way of life. Although prejudice cannot be said to be innate to human beings, with the development of society and the gradual evolution of human desires, prejudice has become a common problem of all mankind. It is a super-evolved bacterium, which is a brother with human subjective consciousness and grows slowly in human secular ideology. But people haven't noticed that this cancer is getting bigger and bigger in their heads ... People always have different views on the same thing, an oil painting depicting the sun. Sunlight shuttles between buildings. Pessimists think it is sunset, optimists think it is sunrise. According to the painter, it is indeed sunrise. Pessimists feel that everything in the world is gloomy, and all the good things in his eyes are destructive and biased in his eyes. A beautiful girl is pursued by two boys at the same time, one is a childhood friend and the other is a rich man. But the girl's mother married her daughter to a young man regardless of her daughter's idea, and kept saying that it was for her own good. In this mother's mind, she only thinks that her daughter will be happy if she marries a rich young man and becomes a housewife. Prejudice often destroys the happiness of a couple. Women should not be busy with work all day, but should clean up housework and take care of children at home; It is impossible to find a good job without a college degree; Someone lost money, it must have been stolen by a poor man; It's a pity that my husband is shorter than my wife.

Prejudice is very different from looking at the scenery. The scenery hasn't changed, but it will be very different if people who look at the scenery wear colored glasses. Of course, people who are biased do it on purpose, generally following the example of Huineng, a famous monk in the Tang Dynasty, and advocating "nothing outside the heart". When you look at things and think about problems, you can't help adding a pair of colored glasses to your heart, and then you will shrink your head in your stomach, just like Xingtian people, and you will be blinded by audio and video. In this way, prejudice is formed. When each of us is in the same environment and different moods, prejudice will suddenly pop up from behind our inner sunglasses. On the same night, "happiness is too short and boredom is too long" is the truth. The world is like this, and so is the world. Bonheur in French consists of two words: good and hour. langweile in German literally means "long time", which is neither long nor short, but it is precisely because of the prejudice of the mind that pleasure and boredom are also there. "Prejudice" and "preference" are inseparable twins. "Preference" inevitably produces "prejudice", and "prejudice" favors the favored. The description of woodpeckers in Shelley's To Jenny-A Memory says that "Zhiyin Mountain is more secluded", and Wang Ji's famous sentence also says that "knowing makes Lin Jing more secluded", while Wang Anshi's world outlook is quite different from the previous two. He wrote: "A bird without singing the mountain is more secluded." Later generations ridiculed it as a poor pen, which shows that Wang Anshi thought it was "crow and magpie noise" that ruined the scenery, while Shelley and Wang Ji praised it as "birds crow and swallow words". We are afraid of prejudice, and we are even more afraid of prejudice. "Everyone is fighting for gold, and there are no bones." So I doubt myself for no reason, but I doubt others more. I often look at my conscience to see if I wear colored glasses, and I often suppress the gap in my heart to prevent "preference" from taking advantage of it and "prejudice" from taking advantage of it. But if you go on like this for a long time, you will be physically and mentally sleepy. Then there is a prejudice: "I am fair! No prejudice! " Schopenhauer wrote in Chapter 278 of Philosophical Essays that "thinkers should be deaf", which is very reasonable. Otherwise, the ears are not clean and the body and mind are polluted, which will lead to prejudice and hypocrisy. But this is only forced to guard against prejudice. If you want to eradicate it, I'm afraid you can only grow old. Qian Zhongshu said that everyone is eccentric, because everyone's heart is on the left, and eccentricity is eccentricity. Eccentricity leads to prejudice, which erodes our minds, so our thoughts are biased. This is why Dante wrote in the Divine Comedy that "even the sun in hell is cold and quiet" and "the devil prefers cows, so it is often cow-shaped".

The heart can't grow back to the center, so when we think about things, we might as well use one less heart and one more impartial brain to eliminate prejudice. Of course, the colored glasses in your heart must be removed. According to Aikman's conversation with Goethe at 1830, Goethe hates people who wear glasses.
