What is the difference between the practice of materialism ontology and epistemology? Just write at four or five.

A remarkable feature of Marxist philosophy is its practicality. As a modern form of materialism, this philosophy has realized a philosophical revolution because it runs through its own world view, epistemology and social history view with scientific practice view and conscious dialectics.

The scientific concept of practice is the breakthrough and key to realize this philosophical revolution. This is also an important symbol of all other philosophies, including those different from the old materialism. Conscious dialectics combined with this modern materialism is its essence and living soul. In view of the extreme importance of dialectical and practical viewpoints, we can call Marxist philosophical world outlook "dialectical materialism" or "practical materialism". The former is a traditional title since Dietzgan, plekhanov and Lenin, while the latter is a popular saying in recent years. Both of them highlight the essential characteristics of Marxist philosophy from one side. Especially under the contemporary historical conditions, human beings use modern science and technology to control various natural forces, transform the world and build a new life, showing increasingly powerful essential strength and subjective initiative. Therefore, it is of inestimable theoretical and practical significance to summarize the internal relationship between Marxist philosophy and real life and its guiding role with "practical materialism".
