I don't remember a famous person who said, "The truth is in the hands of a few people", and the minority must obey the majority. In the end, the truth is still in the hands of most people, and that's how people follow suit. The first man said a word, and the second man heard it and told him. At this time, the third person objected. The fourth person saw that there were two people on one side and only one person on the other side, so he told the two people. It can be seen that the crowded party does not necessarily have its own ideas, and many people go for the sake of crowding. The truth may be buried in the process.

Maybe you will have a similar experience to mine. When answering the teacher's question "Yes", your answer is obviously different from that of most people, but you are still echoing most people's answers. When the brave man gave different answers, the teacher said that only he was right. At this time, you find that yours coincides with his. In fact, conformity is hypocritical, fearing that you will be laughed at if you answer wrong. That's just vanity. It is your vanity. It can be seen that conformity is the enemy of exploring truth.

As long as it is what we get through thinking, we must stick to it no matter how much resistance there is. Edison came to the conclusion after repeated thinking that there is always a substance that can emit light when it is electrified. But at that time, many authoritative scientists agreed that this idea was impossible and unscientific. However, Edison firmly believed in his idea and finally invented the incandescent lamp. Therefore, as long as you really think, you can boldly doubt all the "truth" around you. The philosophy and laws drawn by many philosophers and scientists were discovered by some scholars in the process of learning, and were overthrown or supplemented. Truth can only be discovered through exploration. Only by boldly doubting on the basis of predecessors can we learn more nutrition, make progress and get closer to the truth.

Learning is expensive and suspicious, that's right. But you can't just doubt it. Doubt for the sake of doubt. Have you ever doubted that Jordan can play basketball? Do you suspect anyone wants to eat? We can't go from one extreme to the other. Learning is expensive and doubtful, so we should put "learning" in the first place, and "learning" and "doubt" cannot be juxtaposed. Because "doubt" is only the behavior that conflicts with the conclusion of the formula in your learning process. So, don't blindly doubt without thinking. You may ask, we are always skeptical about this and that. Isn't it more difficult to learn things like this? Actually, it's not like this. Because people are naturally suspicious, don't you accept everything others say without reservation? Without thinking, I completely believe that it is ideological laziness. This mentality is always passive. On the contrary, only the brain that often doubts and asks questions will have problems, seek answers and have deeper exploration.

If later scholars stick to the old sayings of predecessors, there will be no new problems, no new discoveries, all academic research will stagnate and human culture will not progress. Our textbooks are constantly changing. Why? This is because there are imperfections or mistakes in the book. Why did you find them? Because of skepticism. Although we study on the shoulders of our predecessors, there will be gaps in their shoulders, which need to be filled with "learning is expensive and doubtful"

So I think-learning is expensive and doubtful.
