What is truth according to the reality of life?

Practice is the only criterion for testing truth! There is no absolute truth!

You may meet good people today, but there are still many good people in society. Tomorrow you will meet many bad people and suddenly feel that the society is still very dark, so your thinking about life is always closely related to what you encounter and develops continuously. With the increase of experience, the understanding of life is becoming more and more thorough and rational! This is actually the process of our growth!

Because our practice is absolute, we not only admit that practice is the standard of truth, but also look at the standard of practice from the perspective of development. Practice is constantly developing, so as a criterion for testing truth, it has both absolute and relative significance. As far as all thoughts and theories must be tested by practice, it is absolute and unconditional; As far as practice has its limitations at a certain stage of its development, it is relative and conditional, because it cannot completely confirm or completely refute all thoughts and theories unconditionally; However, what can't be answered by today's practice will be answered in the future. In this respect, it is absolutely. The dialectical materialist epistemology's viewpoint of dialectical unity of absoluteness and relativity of practical standards is the viewpoint that any thought and any theory must be constantly tested by practice without exception, that is, the viewpoint of truth development. Any kind of thought or theory, even if it has been proved to be true at a certain stage of practice, still needs to be tested by new practice and supplemented, enriched or revised in its development process. Chairman Mao pointed out: "The history of human cognition tells us that the truth of many theories is incomplete, and their incompleteness has been corrected after the test of practice. Many theories are wrong, and their mistakes are corrected only after the test of practice. " He also pointed out: "The movement of change in the objective real world will never end, and people's understanding of truth in practice will never end. Marxism-Leninism did not end the truth, but constantly opened up the road to understanding the truth in practice. " (On Practice) Marxism emphasizes that practice is the criterion for testing truth. In practice, the understanding of truth will never end, that is, it is admitted that our understanding cannot be completed once or finally, or due to the limitations of history and class, our understanding may make mistakes and needs to be tested by practice. Everything that has been proved to be wrong and unrealistic by practice should be changed and should not be adhered to.
