Man's knowledge emerged this way. He first had a perception he wanted to express, so he made sounds and language emerged. In order to decode the world, he invented mathematics. These added two things onto perception, extensions of perception, and later on there emerged the higher pursuits of man, such as art. There are two parts to art, the first belonging to the material, and the other belonging to the mental. Later on it split apart, with one part going on to be scientists, and the rest going on to research perception. Each different depiction method is a new re-expression of man's perception and spirit, a re-explanation of man's perception.

人类的智慧是这样出来的，他首先有感觉要表达，就发出声音，语言就出来了，为了解读世界，发明了数学，这就在感觉本体上面添加了两个东西，感觉的延伸，最后出现了人的更高的一些要求，比如艺术，艺术里面有两个部分，一部分属于唯物，一部分属于唯心，后来就分流了，一部分去做科学家，剩下的就是研究感觉，每一种描述方式都是对人的感觉和精神的重新再表达，重新解释人的感觉。
