1. Definition of truth: truth (including absolute truth and relative truth) is the correct cognition of objective things and their laws by people under certain time and space conditions
Truth is not an objective law! ! , For example, the heliocentric theory at the beginning was in line with the observation conditions of human beings at that time, and there was no error, so people thought it was the truth, and then the technology developed, and the heliocentric theory was denied.
2. Limitations of truth:
Time: The sun is bigger than the moon. This should be the absolute truth. It cannot be said that the sun is smaller than the moon. But if the time is infinitely magnified, before the sun and the moon are born or after the disappearance, it is meaningless to compare the size of two non-existent celestial bodies
Space: The sun rises from the east every day. "There is clearly an element of truth to this statement, but it is only true that certain spatial conditions exist. If you stand on the North Pole, the sun does not rise in the east every day.
3. Truth is human cognition, and there is a process of development and perfection
That is to say, human cognition of objective laws is cumulative and gradual. It was always wrong and one-sided at the beginning, and then I realized that it was not the case, so I took a step towards the truth. Later, it was found that the new understanding was not perfect, so it was supplemented. These cognitions are preserved in the form of words, and later people continue to perfect them on this basis, so that they are getting closer and closer to the truth.
