"Knowledge is limited", and quite limited. When people face a huge unknown space, they often come up with their own explanations. The ancients were overwhelmed by the power of thunder, so they proposed their own explanation of "Thunder God, Heaven" and worshiped it. Later generations called it superstition. Superstition refers to people's blind belief or worship in things. Superstition in a narrow sense, according to the customary customs after the liberation of our country, specifically refers to people's thoughts and behaviors that believe in astrology, divination, feng shui, fortune telling, gods and ghosts, etc. Superstitious activities generally refer to activities such as drawing lots, fortune-telling, fortune-telling, fortune-telling, fortune-telling, fortune-telling, fortune-telling, exorcising ghosts, and dancing with gods, etc., engaged in by folk magicians, witches, fortune-tellers, and Feng-shui masters. Superstition originally refers to people's blind belief or worship in things, such as superstition in books, superstition in money, superstition in people, etc. Nowadays, people generally believe that superstition is due to the lack of judgment and unclear understanding of the nature of things. They develop a special interest in certain things and truly believe in them, and then believe in themselves to the point of belief, and even to the point of belief and no doubt. Superstitious people are often fascinated and fascinated by a certain thing or phenomenon, and then become addicted to it and believe it without doubt. Superstitious people also tend to be laissez-faire and blindly attach "faith" and "worship" things and statements to positive and disdainful actions. It seems that "superstition" is a general term, just like the word "management", which includes business management/administrative management/warehouse management/financial management/hospital management/school management, and has many uses. And "superstition" will also include: religious superstition/force superstition/wealth superstition...etc., etc. The characteristics of superstition: ①lack of discernment, unable to fully understand the essence of things; ②lack of discernment, and yet Believe a certain phenomenon or statement as true, or even believe and worship unswervingly; ③ Blindly attach the so-called "faith" and "worship" phenomena and statements to positive and disdainful actions. The word feudal superstition is a combination of the two words "feudal" and "superstition". Feng, the first explanation in "Cihai" is "the emperor gave land to his ministers." "Jian" means to establish, set up and erect. The word "feudal" does not have a separate entry in "Cihai". In most cases, it is the abbreviation of "feudal system", "feudal thought", "feudalism", "feudal society", etc., such as "anti-imperialist and anti-feudal" ", "Anti-feudal and anti-superstitious", "This person is very feudal", etc. However, using superstition for other activities is different from superstition itself. Now we are still giving our own explanations for the unknown space. Maybe these explanations are closer to the truth. Anyway, I think they are much more credible and reasonable than "Thor". But when it comes to right and wrong, hey, it's like a group of children watching a movie. They usually point to this person and say "bad person" and point to that person and say "good person". Our science is nothing more than various explanations of the unknown. As for whether the explanations are right or wrong, only God knows. There are many such things in history. Some people are superstitious about geocentric theory and heliocentric theory. Some people are superstitious about Newtonian mechanics, while others are superstitious about materialism. (Objection: Science is not the explanation of the unknown at all. This should be left to philosophy (including various philosophies that scientists believe in). Science tells us "how" and gives various predictions of how things will change. Newtonian mechanics is inaccurate But it is a very useful theory. Materialism is metaphysics, not science.) Blind belief in science is also a kind of superstition. The reason why science is science is that any science requires that conclusions must be established on the basis of strict experimental proof. "Practice" "It is the only criterion for testing truth." Therefore, we have reason to require all workers engaged in scientific work to maintain a pragmatic and cautious attitude and strictly distinguish between theories and conclusions. On the contrary, blindly believing in science will become the new superstition!
