- vity of feelings. Objectivity comes from the need for logical unity between consciousness. When you hit the wall, if you do not admit the feeling and say,“I just did not hit the wall”, then you continue to move forward and you will get the feeling of hitting the wall again. Concepts and emotions can be changed at will, but experience cannot be changed at will because it has a specific relationship with people's interests.

The cylinder brain receives the computer-simulated life experience, which may be considered as real life experience by the brain within a short time, but it will inevitably be doubted after a long time on many reasons. First of all, there is no technology that can completely imitate the real environment. Three-dimensional maps or game animations are clearly different from the facts. Second, even if the simulation of the environment is very realistic, the simulation of human responses cannot be realistic. People have a wealth of ideas. Each person has a different personality. Computers cannot realistically imitate the language and behavior of different people. Third, the real brain can dominate the limbs, move around, write and draw, and produce a variety of products that can change the world. Computers can imitate some behaviors, but they cannot imitate the detailed feelings and results of behavior. The brain in a cylinder feels itself like a disabled person. Fourth, there are always illogical contents of simulation. Virtual scenes can be replaced instantly. They can move from China to the USA, from earth to Mars, or suddenly disappear. This is impossible for real scenes. The real objective world has specific laws that are not based on human will. It is an alienation. Subjective idealism can never erase this objective alienation.

Since both Materialism and Idealism have errors, what should be the correct theory? It should be Dialectical Dualism, which is the dialectical unity of Materialism and Subjective Idealism. Marx's Dialectical Materialism also recognizes the dialectical relationship between substance and consciousness, but it does not recognize that the role of consciousness in materialism is a decisive role, and Marx called it as counter-production, but Marx had never explained clearly what is counter-production. Therefore, Dialectical Materialism is an incomplete theory.

Why can't the monkey king in the Chinese ancient novel Journey to the West jump out of the palm of the Buddha? Because the Buddha has written these words in his palm: the subjective world. Buddhism believes that all Dharma is in the heart. It is not only the monkey king, but all people, no matter where you are sacred, what you think and say is completely your own subjective world. Things outside the subjective world must first become subjective before they affect your decision-making. These are the determinants of consciousness over matter.

We live in the objective world, but also in a subjective world. The world can exist in a probabilistic way. Communication is based on trust. Economic operation is based on credit. Probability, trust and credit are all subjective things. Because we live in a world of subjective predictions, so we always worry
