Language is the most economical means to change other's consciousness and control others.[2] We say a lot of words and read a lot of words every day. There are many understandings of each word and sentence. For all of these understandings, the objective world is a part of the subjective world.

5.3 Evaluation

We evaluate a lot of things every day, every commodity needs to be evaluated, power needs to be evaluated, business and battlefield situations need to be measured, love and emotions need to be evaluated, all kinds of things probably need to be evaluated. Different objective things have different values for people, and different other people have different values for the subject. For the same objective existence of things or people, different people often have completely different evaluation, among which only one or a few kinds of evaluations are objective, the rest are subjective. For these evaluations, the objective world is a part of the subjective world.

6. Art and religion

 In novels, films and other art works, most of the characters, plots and scenes are invented out of nowhere and belong to the subjective world. However, some characters, plots and scenes are real and objective, and belong to the objective world. Artists integrate these objective and real things into the subjective art world, and become a part of the subjective world. So in the art world, the objective world is a part of the subjective world.

There are no gods and ghosts in the objective world, they are all artificial and belong to the subjective world. However, the image, behavior and psychology of gods and ghosts are similar to people, because people have unrestrained imagination and innovation, which based on real and objective people and the world. Thus the objective world becomes a part of the subjective religious world.

7. Conclusion

 In the objective world, the value of simple and low level systems is relatively small, and the complex and orderly advanced systems have great value. The civilization of human society is complex and orderly advanced system. The priority of philosophy is to reflect the commonalities of these advanced systems with simple theories. Games of thought, including prediction, decisions, wishes, speculation, understanding, art and religion involve all of our production and living practices and all of human civilization, are of great value. For all these games, the objective world is a part of the subjective world. So the world view of taking the objective world as a part of the subjective world is of great value. The subjective world and the objective world are the dialectical unity relationship containing each other.

What we call the objective world is never the objective world itself, but only the objective world in our mouth and mind. Many materialists have been trying to prove that the objective world does not depend on people. In fact, this question does not matter. They are wrong to think that answering this question justifies the Materialism. Philosophical theory is great not because it reflects the world objectively, but because it provides a fake but valuable overall understanding of the world. Objectively speaking, the subjective world and the objective world do not contain each other, but the Dialectical Dualistic world view is the most valuable overall understanding.
