Where does the material concept of idealism come from?

The material view of dialectical materialism comes from Lenin;

"Matter is a philosophical category that marks the objective existence. This objective reality is perceived by people through their feelings. It exists independently of our feelings and is copied, photographed and reflected by our feelings. " (Selected Works of Lenin, Volume II, People's Publishing House, 1995, p. 89. )

Marxist view of matter has rich and profound theoretical significance;

First, adhere to the principle of objective reality of matter, adhere to materialism monism, and draw a clear line with idealism and dualism.

Second, adhere to the theory of dynamic reflection and knowability, and strongly criticize agnosticism.

Third, it embodies the unity of materialism and dialectics.

I have already answered this question, so I will post it for you.

Fourthly, it embodies the unity of materialistic view of nature and materialistic view of history.
