The criterion for judging the value of knowledge lies in practicality, considering whether human beings can create new substances and gain strength and motivation.

Chinese word meaning

1. The word "knowledge" of "knowledge" sounds like an arrow. "Arrow" means "archery" and "mouth" means "talking". The combination of "arrow" and "mouth" means "talking like an arrow, talking like a bull's eye". Original meaning: exactly right (exactly right). "I don't know" or "I don't know" is an inaccurate word, just like archery misses the bull's-eye. Whether the arrow is accurate can be confirmed by the target reporter; Whether the words are correct or not can be tested by the public. For example, Halley, a British astronomer in the18th century, claimed that he knew the behavior of Halley's comet and predicted that it would reappear in 1759. Later, in1759,65438+10, 2 1, people really saw this comet again. Harry is right. This is "knowledge".

2. The word "knowledge" of "knowledge" in traditional writing comes from words and sounds. The word "Xu" follows the tone of Ge, and Shuowen claims that the meaning of this word has been lost because of the teacher's interruption. But in fact, we can understand its original meaning now. The word "Xu" originally refers to the square drill of ancient troops from sound to music. "Sound" refers to the instructor's password sound (including drums, golden sound and soldiers' shouting and killing sound), and "Ge" refers to the soldiers and their weapons participating in the exercise. With a series of instructions from instructors, the army will move forward or backward as a whole, left or right as a whole, move forward in rows in turn, fight together to the left, fight together to the right, and so on. Looking down at the army training from the reviewing stand is like watching the group gymnastics performance from the stadium stands, and we can see all kinds of figures formed by the uniform movements of the participants. Therefore, the original meaning of the word "virtual" is "orthomorphism and its transformation" Everything has this meaning from the word "Xu". For example, "weaving" is to add patterns to the fabric manufacturing process to make it a printed fabric. For another example, the "national flag" is to add national patterns to the flag cloth as a national symbol. For example, the flag of China has a five-star pattern, the flag of the United States has a star stripe pattern, and the flag of Britain has a herringbone pattern, and so on. For another example, the "post" is a team gymnast, whose task is to receive instructions with his ears and then make the required actions. The result of each participant's doing this is that group calisthenics can change all kinds of graphics. To sum up, we give the original meaning and extended meaning of "knowledge" here. Original meaning: describe the shape and details of the pattern in language. Extended meaning: difference, discrimination. For example, "literacy" means "recognizing characters according to their glyphs, structures and strokes".

3. The original meaning of the word "knowledge" in Chinese: it refers to academics, culture or learning.

What is knowledge? What is the use of knowledge?

The definition of knowledge is still controversial.

China's definition of knowledge is generally from a philosophical point of view. For example, the entry of "knowledge" in "China Encyclopedia of Education" states: "As far as its content is concerned, the so-called knowledge is the reflection of the attributes and connections of objective things and the subjective image of the objective world in the human brain. As far as the form of activity is concerned, sometimes it is manifested as subjective perception or representation of things, which belongs to perceptual knowledge, and sometimes it is manifested as the concept or law of things, which belongs to rational knowledge. "

From this definition, we can see that knowledge is the product of the unity of subject and object. It comes from the outside world, so knowledge is objective; However, knowledge itself is not an objective reality, but a reflection of the characteristics and connections of things in the human brain and a subjective representation of objective things. Knowledge is produced on the basis of the interaction between subject and object through the reflective activities of the human brain.

What does it mean to understand knowledge?

Be able to use knowledge flexibly and solve problems.

One of the signs of understanding is that the object you understand can be expressed in your own words, including the reorganization and change of language materials. If you don't understand something accurately, it is difficult to express it in your own words, or you can only recite the original text, indicating that you don't really understand that sentence or that thing.

Another sign of understanding is that you can independently complete the required actions according to your own understanding of something. If you can only follow the instructions of others, you can't think that there is a real understanding. Practicing this object usually helps to understand. In the process of understanding, oral expression and actual action are sometimes inconsistent. A good understanding should be a combination of the two.

When understanding things, we must use past knowledge and experience, or master new knowledge and experience on the basis of existing knowledge and experience. The existence of past knowledge and experience has an important influence on the smooth progress of understanding. The combination of words and visual images plays an important role in understanding.

Extended data:

Understanding, there are three levels:

Low-level understanding refers to perceptual understanding, that is, being able to identify and identify objects, and to say their names and know what they are;

The middle level of knowledge is to reveal the essence and internal relations of things on the basis of perceptual level, which is mainly manifested in being able to understand the connotation of concepts, principles and laws and know what they are;

Advanced understanding belongs to indirect understanding, which refers to further systematization and concretization, re-establishment or adjustment of cognitive structure, mastery of knowledge and extensive migration of knowledge, so as to know what you are.
