"Learning without thinking is useless" is an ancient philosophy of China, which pays attention to improving one's self-cultivation through introspection, and Confucianism is no exception. "Thinking without learning is dangerous" is similar to "a threesome must have a teacher".

Zhu's Annotation to the Analects of Confucius in the Southern Song Dynasty said: "Confucius said:' Learning without thinking is useless, and thinking without learning is dangerous. I don't want to move, so I feel faint and have nothing. If you are not used to it, you will be in danger and uneasy. Cheng Zi said, "Learning, interrogation, careful thinking, discrimination and perseverance are five things, and abolishing any of them is not learning. "
