The famous sentence of Laozi's dialectical thought is as follows:

1. Weakness is better than strength.

people will think that strength is better than weakness in the early and middle stages of summing up the truth. It is not until the study of knowledge has reached a considerable height that we will know that weakness is better than strength.

like this, the high-level conclusion is contrary to the view in the early and middle stages of exploring truth, and this high-level conclusion is called dialectical.

Weakness is better than strength, which is a dialectical thought of Laozi.

2, goodness is like water.

water is active in nourishing everything, but it is active but not in a high position, but is willing to flow to and live in low-lying areas. Laozi believes that this spirit of being active but unwilling to live in a high position and not seeking returns is the first-class goodness.

In the early and middle stages of summing up the truth, people will think that people should go higher and strive for the goal of a happy life. However, Lao Tzu praised the water flowing downwards, praised the water's willingness to live in low-lying places, and said that this is the first-class goodness.

this is contrary to the idea of studying truth in the early and middle stages, and it is also Laozi's dialectical thought.

3. Liang Jia is hiding in Ruo Xu, and a gentleman is virtuous and looks like a fool.

a really good businessman never shows his wealth, just like a poor man. A gentleman with high morality does not show his morality, but looks like a fool.

In the early and middle stages of summing up the truth, people will praise those who love to show their talents and wealth, and those who look beautiful. But Lao Tzu, a wise man, thinks that those who don't reveal their wealth are the ones who really know how to do business. Those who don't show their morality are truly high-moral people.

This truth of his is contrary to the initial and middle stages of studying truth, which is also Laozi's dialectical thought.
