Dr. Xiang Ye absently made a remark in Nietzsche's circle of friends: "... From then on, there is no hierarchy of knowledge, no outline of knowledge, all knowledge is equal, no important or unimportant, only fashion renovation. The result is the mass production of knowledge, but it only makes people know more and more trivial things in vain, which not only fails to concentrate their thoughts, but also leads the so-called "scholars" to fall into vulgar philistinism and spread kitsch. ..."

Dr. Ye must have some feelings. This phenomenon does not seem to exist today. Is it worse now than Nietzsche's time? Chicken soup was spilled all day, and chicken feathers were scattered all over the floor.

Is modernity and tradition, advanced and backward, innovation and conservatism equal to right and wrong, good and evil, good and bad?

Modernity and tradition, advanced and backward, innovation and conservatism often depend on certain environment, fields, things and times. ...

People are always confused by "new" and always think that "new" will definitely overcome everything. I don't know how many "new" died halfway. And how many "old" have lasted for tens of thousands of years, living in human society, living in the depths of people's souls and living in the vast universe.

A new technology may be technically better than the old one, with higher implementation skills and more energy, but is it necessarily better? For example, chemical fertilizer is to pig manure and cow dung.

Is the new discovery better than the old one? Have you ever wondered what this "new" is? This "newness" is only an act of "discovery", and the "discovered" new discovery already exists, not "newness". The difference between new discoveries and old discoveries is not "new" or "old". The discovery of "new" and "old" reveals the original existence, and the difference is only the order of discovery. For example, chemical elements existed before being discovered by humans. Another example is fashionable quantum entanglement. Perhaps this "new" discovery was discovered by our ancestors and was forgotten because it was not "good" under the technical conditions at that time. Only today have these traditions been rediscovered by us, and they are "useful" to us today, so we hail this "new discovery" and think it is an improvement on the "old discovery".

History is certainly developing, but are times necessarily progressing? Dress is changing, the way of travel is changing, the form of communication is changing, and the terminology is constantly being refurbished. Does all this mean that the times are progressing? It is precisely because of the progress of technology and the development of network that people's understanding depends more on the dissemination and indoctrination of the media than on independent thinking and ideological agitation.

The development of science and technology has brought infinite imagination to the future of mankind. The development of science and technology can solve many human problems. It is precisely because the development of science and technology has created many problems for human beings, so human beings must use new scientific and technological inventions to solve the problems brought about by these scientific and technological developments. However, human beings must know that technology can never solve all human problems. This is the field of thinking. This kind of thinking is very hard and enjoyable. Difficult, because we have to struggle out of the quagmire of "vulgarization and kitsch"; Happiness comes from a thorough understanding of knowledge and a bright heart.
