On the principle and methodological significance of the law of mutual variation of quality

The law of mutual change of quality is one of the three laws of Marxist materialist dialectics. The development process of things goes through two States: quantitative change and qualitative change. Everything is the unity of quality and quantity. Universality of the law of mutual change of quality: No matter in nature, human society or thinking field, the change and development of everything follows the law of mutual change of quality. Diversity of qualitative and quantitative changes.

Two basic forms of qualitative change:

First, explosive leap: qualitative change has the form of fierce external conflict, and the old and new forces do not give in to each other. Only fierce conflicts and life-and-death ways can resolve conflicts.

Second, non-explosive leap: a solution to non-confrontational contradictions. Because the opposing sides are in the same fundamental interests, it is possible to solve contradictions through peaceful means.

Quantitative change leads to qualitative change, and qualitative change leads to new quantitative change, which is endless and constitutes the process of infinite development of things. Quantitative change and qualitative change are two basic forms of development and change of things. There are differences and connections between them, and they are interdependent and interpenetrating in the process of development. There are periodic and local qualitative changes in quantitative change, and quantitative expansion in qualitative change.

Extended data:

The size of an object, the speed of movement, the number and order of molecules, the level and speed of productivity development, etc. , are the provisions and performance of the number of things. The stipulation of the quantity of things is also inherent in the things themselves, which exists objectively and cannot be separated from things.

Quantitative change is the necessary preparation for qualitative change, and qualitative change is the inevitable result of quantitative change; Qualitative change and quantitative change are interpenetrating, interdependent and interrelated. In the process of quantitative change of the total amount, there are partial qualitative changes in stages and locality, and in the process of qualitative change, there are also shrinkage of the old quality and expansion of the new quality.

Quantitative change leads to qualitative change, and on the basis of new quality, things begin to change quantitatively again, and so on, forming the regularity of mutual changes in the quality of things. The law of mutual change of quality embodies the unity of gradual and leap things.
