Many people think that only the true, the kind and the beautiful things are good, in fact, many times fake, cruel and ugly things can better meet people's needs. Toy cars are fake, and for children, fake cars can meet their needs better than real cars. Fake flowers and rockeries are all good things, and artistic images and plots are almost all fake. The heliocentric theory is also false, but in Bruno's day, it played a role in advancing history. All drawings and models are fake, they are essential for all kinds of engineering projects. Kindness to the enemy is a crime against the people; the profession of a doctor is to save people; the profession of a soldier is to kill people; those who kill the most are called heroes and brave warriors. Clowns on the stage can bring us joy and artistic enjoyment, there are plenty of beautiful women and handsome men, but many people like Song Dandan and Wang Baoqiang who are not beautiful. The ultimate standard of value is the interests and needs of people, individualism, humanism and evolutionism, not necessarily the truth, the kind and the beautiful. The ultimate standard of truth is not truth and objectivity, but usefulness.

If the physical world view of science is the objective and true world view, then philosophical metaphysics must establish a false and more valuable world view. Of course, the objective and true world view is not completely worthless, but it is far from satisfying people's needs. The vast universe is of little value to human beings. What is most valuable to human beings is our daily life, our interests and needs, and the culture and civilization we have created.

The scientific world view is incomplete, and only the metaphysical world view provided by philosophical ontology is a complete world view. Why do I say that? Scientists only want to give us an objective and true view of the world, but there are many important and valuable things that are not objective and true. Existence is not equal to objective existence, existence includes objective existence and subjective existence. What exists in the subjective world may not be objective, but it is also a kind of existence.

Therefore we can come to a conclusion that if we ignore the existence of these false things, it only shows that our world view is incomplete. If we say that everything in the objective world is objective and true, then these false things do not belong to the objective world, but to the subjective world. So the objective world is only a part of the world. The world view provided by science only describes the objective world, so the world view provided by science is not the complete world view, only the metaphysical world view provided by philosophy is the complete world view, which embraces everything, especially those things that may be not objectively real but have great value.

8.2The world view of Dialectical Dualism 

The world view of Dialectical Dualism is a new world outlook of metaphysics, which believes that the existence of the world includes two parts: the subjective world and the objective world, and they are dialectical and unified relation that contain each other.
