This very program that was brought about in Karl Marx＇s ＂Capital＂ has not been sufficiently expressed in classical or contemporary philosophy. The base of this new Marxist philosophical form is not constructed by the terms of matter, movement, and development overall, but by the conception of the general naturally determined universal process of infinite movement from lower to superior forms of matter. We are aware of four of them： physical, chemical, biological, and social matter. Representing the eternal world as the progressive whole, modern materialism makes nature and proper place of each fundamental science understandable and helps to clarify the location and development future trends of the Man in the world.展开更多
