What is the development view of materialist dialectics?

The development view of materialist dialectics;

Materialist dialectics holds that nature, human society and human thinking are constantly moving, changing and developing, and the development of things is universal and objective.

The essence of development is the progress and rise of things, and it is the replacement of old things by new things. Therefore, we must adhere to the viewpoint of development, that is, the concept of development.

Development is the changing trend of things from simple to complex and from low to high, and its essence is the emergence of new things and the demise of old things.

The development of a thing is often a wave-like process of "imbalance → balance → new imbalance → new balance", and a limited process constitutes an infinitely developing world. In other words, the world can also be regarded as a collection of "processes" of eternal development.

Phenomenon and essence:

Phenomenon is inseparable from essence, and any phenomenon is determined by essence, which is a certain expression of essence (for example, truth directly shows essence from the front, while illusion distorts essence from the back); At the same time, essence cannot exist alone without phenomena, and any essence must be expressed through one or more phenomena.

So people can always understand the essence of things through the analysis and research of phenomena. This process of analysis and research is often summarized as the process of "removing the rough and selecting the fine, removing the false and retaining the true, from this to that, from the outside to the inside".

The difference between phenomenon and essence, form and content lies in the fact that phenomenon reflects essence as an inevitable spontaneity, and form can artificially express content.
