Analysis:
The similarity between materialism and idealism lies in. The ultimate goal they want to achieve is the same, that is, the capitalist world and the human world depict the same beautiful future world; They all respect objective facts, draw their own conclusions and express their views on the basis of objective facts.
The difference between materialism and idealism lies in. Materialism holds that the world is material and the material world can be recognized. With the development of science, mankind will gradually know and master all the material worlds. Idealism holds that the world is subjective or objective, and the spirit dominates everything; Generally, there is an idealistic explanation of objective things first, and then a materialistic explanation; The explanation of materialism always uses science to affirm the phenomenon described by idealism, but denies the conclusion of idealism and draws scientific conclusions; The phenomenon that materialism cannot be explained scientifically is the condition for the temporary existence of idealism. Materialism denies the existence of objective phenomena because it cannot be explained scientifically, and objectively consolidates the existence of idealism. In the face of unknown things or phenomena, people can only look for answers from idealistic explanations, thus moving towards idealism, which makes the broad masses of the people more or less corroded and confused by idealism.
The scientific development process of materialism proves that all the gods in the past did not exist and were replaced by science. It can be inferred that the gods that appeared in the past do not exist, but must be scientific phenomena, and all the gods in the future will be replaced by science.
My point is that all the objective phenomena described by idealism are the science that materialism needs to master. The process of materialism denying the conclusion of idealism is also the process of realizing the scientific development and social progress of human beings, and finally unified on the same goal of materialism and idealism, and human society entered the world of materialism.
