Principal argumentation is an argumentation method that demonstrates arguments through the analysis of events. This method is used in two places in the article: The first place: "Thinking out of doubt, and distinguishing right from wrong out of thinking. After going through the three steps of 'doubt', 'thinking' and 'discrimination', that book is your own book. That kind of knowledge is your own knowledge.

Otherwise, it is blind obedience and superstition. Mencius said that "it is better to have no books than to believe in books", which means that we should have a little doubt and not blindly follow or be superstitious. "The author first analyzes it from the front, pointing out that people must go through the process from doubt to thinking, and from thinking to discernment in order to obtain true knowledge. Then he quoted Mencius' words to explain from the opposite side, pointing out that science can never progress if one blindly believes in books and only follows books. Positive and negative comparison analysis enables readers to realize that the spirit of skepticism is a necessary condition for scientific development.

Part 2: "To accept other people's words without thinking about it or discounting it is ideological laziness. Such a mind will always be passive and will never be able to study. It can only always doubt and ask questions Only when there are questions in the mind, only when there are questions can one seek answers. Only in the constant questioning and solving can all knowledge be developed."

In this analysis, the author first starts with the negative side to explain the problem of not thinking. Harm - You can never learn academically without using your brain. The magnitude of the harm is alarming. Once we get rid of our lazy thoughts and emotions, emancipate our minds, and turn on the machine, we will move from doubt to doubt, and from doubt to solution. When we find solutions, we will have new theories, and academic development and progress will occur. Once the author analyzes it, the reader will know what is right and wrong.
