Smart and stupid.

Confucius said, "Sex is similar, but learning is far away." Confucius said, "I only know about the top, but I am stupid about the bottom."

The master said, "Only first-class smart people and second-class stupid people can't change their nature."

On the one hand, Confucius acknowledged that human beings are all similar in nature, which is very important, because this is the physiological premise that people are born equal. On the other hand, he pointed out two special types of people: smart people and stupid people.

The phrase "only the upper know the lower are stupid" is followed by "learn from each other's strong points" rather than "similar in sex". Those who don't move are learned, not born.

? Why doesn't the acquisition move? Wang Yangming answered this question and asked, "How can you be wise and stupid?" The gentleman said, "It's not that you can't move, it's that you can't move."

? If you don't study when you are sleepy, of course you can't move. People who are sleepy but don't learn are fools.

Learning the day after tomorrow has a great influence on people. Smart people will not be affected by the environment, and stupid people are unwilling to make progress and become better through the acquired study.

People near Zhu Zhechi are black, but shine on you shines on you rather than blue. In a word, the importance of learning environment is self-evident.
