In the field of natural science, the answers to many things are not colorful, but unique and irreplaceable. Even in the field of social sciences, the answers to many questions are not "colorful". People often have only one understanding of the truth of things. Different positions, viewpoints and methods can bring different answers, and incorrect positions, viewpoints and methods can only bring incorrect answers. Therefore, it is correct to encourage and guide people, especially young students, to explore the unknown in the scientific field with colorful ways of thinking, but we should not go to the extreme of thinking that we doubt everything and deny everything, let alone take an irresponsible and arbitrary attitude towards scientific research.

Counterparty: Over the years, we have become accustomed to such a thinking in the process of scientific understanding: there is only one right, except right, and the opposite of right is wrong. It is this "logic" that makes some new ideas, new ideas and new discoveries lose the opportunity to be adopted and considered. The extreme and narrow way of thinking has brought dry thinking, single thinking and decreased creativity to the intellectual community, which cannot be underestimated at all.

In our social life, in the habitual thinking of China people, in today's literary and art circles and academic circles, there are still so many endless and possibly useless arguments, and there are so many arguments of "either you die or I live". They all refuse to think more about the possibility that others are right and the possibility that * * * is right; In the school classroom, there are still so many "only correct"-actually not "only"-"standard answers", which suppress the ideological space of teenagers.
