Dialectical materialism holds that matter is an objective reality that can be reflected by people's consciousness without being transferred. Neither the existence and development of nature nor the existence and development of human society depend on human consciousness.
This objective reality independent of human consciousness is materiality. The whole world is a material world that exists objectively without relying on people's consciousness, and the origin of the world is material.

First, matter plays a decisive role in consciousness. Matter determines consciousness, and consciousness is the reflection of matter. Without acknowledging the opposition between matter and consciousness, there is no objective practical coordinate, and consciousness is the subjective image of the objective world.
Second, consciousness has a dynamic effect on matter. The dynamic role of consciousness is first manifested in that consciousness can correctly reflect objective things, and also in that consciousness can react to objective things. Correct consciousness can guide people to carry out practical activities effectively and promote the development of objective things; Wrong consciousness will lead people's activities astray and hinder the development of objective things.
