Why are you being led by a person of low intelligence?

Because your intelligence is lower than that person's. Scientific theories, philosophical ideas, and artistic ideas have been replaced by one generation after another, and some of these ideas continue to be used by humanity.  All knowledge and language are abstract. The singing of birds is abstract.  Every word you say is abstract. Every word is abstract. Can you see that word in life?  Primary school culture is also abstract. Can you see culture in daily life? When you ask a question, it shows that you have super strong thinking ability and keen insight. The creation of primary school mathematics is a challenge to human intelligence. High intensity intelligent challenge. Live and learn.
