In the higher education class, the teacher did not instill knowledge into us, but learned the knowledge in the form of discussion. He will not teach you how to do it by hand. Instead, after you have learned it, everyone will sit together and start to discuss it. Everyone can put forward their own opinions. Each viewpoint is not denied. Instead, it is free to speak and discuss and share all kinds of views. After the collision of ideas, we have a deeper understanding of knowledge.
Not only in terms of learning knowledge, but also in terms of common things and misoperations, Mr Mi will also let everyone discuss them together. There is no absolute standard of correctness. When all kinds of opinions are put out, I think it is better and better, even if there was no conclusion at the time, many things will be self-evident with the time and experience of events. Many things cannot be solved immediately. Therefore, discussion and accumulation are necessary. Communication is an important capability and a learning method, when you can fully express your thoughts, it proves that you have a deep understanding of something.
I think it is like the free market of views put forward by Hamilton in his book on freedom of publishing, so that all views, regardless of merits and demerits, can be put on the table and discussed openly and honestly, in this way, the argument becomes clearer.
This also confirms the famous saying of advanced training: Nothing is absolute, and changes will never change. Nothing is wrong, and only what is more appropriate.
