What does the character of fake, large and empty of philosophy mean? Say fake first. Don't think that fake is all bad. If the merchants sell fake goods to deceive people, it is of course an immoral behavior, but some fake goods are good and have positive value. For example, precious metals like gold and silver are real money, whereas all paper money is fake. But paper money works. We can't live without paper money. Fang Qingping, a Crosstalk performer, said, "When a monkey learnt to make fake things, it became a human being." That's a brilliant comment.

    An architect draws a building on paper. Is the drawing real? Of course not. The building on paper is a fake one. You can't live on paper. If you spend millions on a house, and the real estate agent only sells you a blueprint, you can't accept. But the process of building can not leave the drawings, although the building on the drawings is fake, but if there is no fake buildings, there will be no real building. The better the architect fakes, the better the real building will be. 

    The car on the drawing doesn't run, it is stationary. But the better the drawing of the car on drawing, the faster the real car will run. To borrow the words in Main Road of Han Feizi: "Virtual is to know the real condition, static is to know the active."[1] Some fake things are good for people and some are bad for people. With these beneficial things, the higher the level of human fake, the more developed human civilization, the happier human life.

    All rational thinking is fake. The word fake here mainly refers to the difference between human consciousness and material. Material is true, consciousness is fake. With the process of human civilization, people's consciousness has changed from simply reflecting reality to abstractly and systematically recognizing reality, and then forming theories and scientific and technological systems. In this process, the level of making fake things is constantly improving. All drawings, models and scientific theories are fake stuff. With the development of science and technology, fake things gradually develop from less to more, from simple to complex, from disorder to order, from fragmentation to systematic perfection. This is how human civilization evolved.

    Scientific theory is fake, but it seems to be quite true, closer to objective reality. And philosophy is the most fake, because its theories are the furthest from reality, its concepts are largest and emptiest. Matter is real, and real things like fire and water were first taken as the Origin. But later philosophers regarded these theories naive. The Origin must be the most fake and abstract thing, it can not be real objective and concrete things.

    Then let's talk about large. I saw a lot of tables and the concept of table came into being. Concepts come from abstractions of multiple things. Objects are true, concepts are fake. The concept has a certain extension, the extension of the concept of table is thousands of tables. The word table is very small, but it has a very large extension. All abstract scientific concepts have great extensions. The more abstract the concept, the larger the extension. The extension of furniture is larger than that of table because furniture is a more abstract concept than table. Compared with scientific concepts, philosophical concepts and theories have a larger extension, even covering the whole universe and all aspects of things. So philosophy is large and fake.
