Mao's conversation with Nobel Prize winner Tsung-Dao Lee in 1974
Chairman: All absolute truth cannot be seen or touched, but it exists in relative truth. Both relative and absolute, unity of opposites, unity of opposites. Why do you all agree with me? Don’t you refute me?
Li: Because you are right, what we are looking for is relative truth, not absolute truth.
Chairman: Relative truth contains absolute truth.
Li: Yes. In physics, every truth is relative and temporary, but we regard the entire process as if it were an absolute truth. The process of everything is a relative progress. This process seems to be the absolute truth, but what we understand is only the relative truth.
Chairman: There are absolutes in it. Please tell me about your invention and creation.
Li: We don’t have any inventions. They are just results obtained through experiments. We gain understanding through the results, and we also want to generalize them. We also take a step back and think about whether we can do some new experiments to correct and prove whether the original ideas are correct. As a result of the experiment, the idea was revised again and again. Start with experiments, lead to theories, make explanations and conjectures, and then conduct experiments. From perceptual knowledge to rational knowledge, we then make a leap to further understanding and further experimentation. The process is almost the same, starting from practice and returning to practice.
Chairman: Practice-theory-practice, not theory-practice-theory.
