The fundamental difference between materialism and idealism is

The most fundamental difference between materialism and idealism is that materialism believes that matter determines consciousness, while idealism believes that consciousness determines matter.

Materialism asserts that matter is the origin of the world, matter is the first nature, consciousness is the second nature, and matter determines consciousness, while idealism advocates that consciousness is the origin of the world, consciousness is the first nature, matter is the second nature, and consciousness determines matter.

The difference lies in the fact that the objects of world unity are different.

Idealism advocates the unity of the world in the spirit, in which subjective idealism advocates the unity of the world in the spirit of man, and objective idealism advocates the unity of the world in a mysterious "objective spirit"; Materialism asserts that the world is unified with matter.

There are two forms of idealism: subjective idealism and objective idealism. The representative figures of the former include Berkeley, Mach, Wang Yangming, etc., who advocate that the human spirit is the origin of the world, and that everything in the world exists in the human spirit. The representative figure of the latter is the famous Hegel, who advocated that the "objective spirit" that exists independently of man and nature is the origin of the world, and that everything in the universe is "the product of the objective spirit".

The question of who decides who decides who is matter and consciousness. Materialism holds that there is matter first and then consciousness, and that matter determines consciousness. Idealism, on the other hand, believes that there is consciousness before matter, and that consciousness determines matter.

Idealism is a philosophical belief that reality is primarily spiritual or spiritual in nature and that the material world is a product of the mind or consciousness. Materialism, on the other hand, holds that matter is the fundamental, ultimate reality, and that the spiritual and spiritual aspects of reality are derived from or dependent on material processes.

Therefore, the main difference between the two is their perception of the nature of reality. Idealism asserts that reality is spiritual or spiritual in nature, whereas materialism asserts that reality is fundamentally material or material.

The fundamental viewpoint of materialism is to recognize that the essence of the world is matter, that there is matter first and then consciousness in the world, that matter determines consciousness, and that consciousness is a reflection of matter. Materialism believes that the original principle of the world is matter, matter is the first consciousness, and matter determines consciousness.

Idealism is a philosophy that is fundamentally opposed to materialism. The fundamental view of idealism is that the essence of the world is consciousness, and that it is not matter that determines consciousness, but consciousness that determines matter.

Idealism holds that the origin of the world is consciousness, consciousness is the first matter second, and consciousness determines matter. The fundamental difference between the two is whether or not to admit that the origin of the world is matter, and whether to admit that matter determines consciousness.

To put it simply, idealism is subjective, and materialism is objective.
