Quantitative change and qualitative change principle

① Quantitative change is the necessary preparation for qualitative change, and qualitative change is the inevitable result of quantitative change.

② Qualitative change can not only complete quantitative change, but also open the way for new quantitative change.

③ There are some qualitative changes in the total quantitative change, and there are quantitative changes in the qualitative change.

④ Two kinds of metaphysics that separate the dialectical relationship between quantitative change and qualitative change: "radical change theory" and "vulgar evolution theory".

"Cataclysm"-only recognizing qualitative change and denying quantitative change;

"Vulgar evolutionism" ―― only acknowledging quantitative change and denying qualitative change.

They split the dialectical relationship between quantitative change and qualitative change and denied the development of things.

Quantitative change and qualitative change methods

(1), adhere to the principle of moderation.

Since quantitative change can only keep its original nature within a certain range and limit, when we need to keep the nature of things stable, we must control quantitative change within a certain limit. Pay attention to the discretion, master the temperature, and adhere to the principle of moderation.

(2) We should seize the opportunity to achieve leapfrog development.

The development of things is ultimately achieved through qualitative change, and there is no development without qualitative change. So the quantity has changed to a certain extent, and only by changing the original nature of things can we move forward. We should decisively break through its scope and limit, actively promote qualitative change and realize things.

The leap and development of things.

(3) the accumulation of attention.

The development of everything starts with quantitative change. Without certain accumulation, it is impossible to change the essence of things and realize the leap and development of things.

Since quantitative change is a necessary preparation for qualitative change, qualitative change depends on quantitative change, so in learning and practice, we should first do the hard work of accumulating quantity, have a down-to-earth and hard-working spirit, do small things bit by bit, oppose haste makes waste, get immediate results, pull out seedlings to help, and know that haste makes waste. It's like opening a door. If you push hard, it will bounce back and close, and then push slowly to open it. Li Zehou said that the way to realize democracy in China is the same as opening the door, and we should not be impatient. Quantitative change is a necessary preparation for qualitative change, which is a philosophical truth. Laozi said: "Learning is not refined, but Tao is not refined." . "Increasingly" and "daily loss" are both processes of quantitative change. In building socialism with China characteristics, we should also pay attention to the accumulation of quantity and gradually realize the goal of modernization. Correctly handle the relationship between reform, development and stability.

(4) Since qualitative change is the inevitable result of quantitative change, it is regular and independent of people's will, then we should be full of confidence and belief in winning when accumulating quantity. Don't give up or lose confidence because of the long and arduous quantitative change, but believe in the law and believe that qualitative change is bound to happen. Not everyone can stick to the quantitative change process that hurts the bones and hurts the bones. Without faith and perseverance, people often give up halfway, so after all, there are not many winners. Not only the end point of quantitative change is meaningful, but also the process of quantitative change is meaningful. One of the sources of this meaning is the traceability of qualitative change. The retrospection of the qualitative change goal makes the difficulties and hardships in the process of quantitative change meaningful.

Since qualitative change can embody and consolidate the achievements of quantitative change and open the way for new quantitative change, we should attach great importance to qualitative change in study and practice, and dare to break through when quantitative change can cause qualitative change, and dare to break new ground and innovate, so as to push our work and career to a new stage. Don't be a mediocre person who is content with small progress.
