Before we can build a building, we have to design it and draw complete engineering drawings. The completed building is a real objective existence. Before the building is built, the building is not existent. But this non-existent building exists in the designer's mind with wealth of contents, including its various parts of the structural dimensions, the materials used, strength requirements, fire protection arrangement and many other things. None of these contents has been realized in the real building, all of them are fake and non-existent contents, all of them are the product of consciousness and thought in the human mind. But the non-existent contents are very important, and without the fake contents there would be no real building.
All human engineering constructions have such a process, consciousness first, material second. Man first creates some fake non-existent things in consciousness, and then creates a real objective existence in reality. These fake consciousness and thought products are the core contents of human civilization and culture. Whether human civilization is developed is first reflected in these non-existent fake contents.
3.The Objective World cannot Influence Decision Making
Each person can only make decisions and act according to his own subjective world. The world outside the subjective world can influence the effect of his behavior, but does not affect his behavioral decisions. For example, there was a stone in front of me. I didn't see it, so I kept walking and tripped and fell flat on my face. Next time I walk here, I'll try to walk around it or over it. This stone is outside my consciousness, and whether I see it or not, it will affect my practical effect and trip me up. But this stone doesn't affect my decision making. When I didn't see it, I went straight ahead. But the second time I came here, my decision changed. What changed my decision? Not the stone of the objective world, but the stone of the subjective world in my mind. Because when I saw the stone, I added a stone to my subjective world. The stone was a logical structure that I have created in my head, the result of a thought game in my head that can influence my decision.
