There are three manifestations of the "real world" in western traditional philosophy: Plato's "ideal world", Christianity's "another world" and whose "thing itself"

What kind of world is a hypothetical world, because they are all created by instinct, and only some natural laws are used as platforms. When that kind of world returns to the real reality, the missing part of the law will be made up, which is the same as the world you are in now. So this philosophy can be seen and thought about, but it can't be taken seriously.
