The premise is to define human beings as consciousness + body, and then to explore the essence of human beings. For example, if consciousness could be downloaded to a computer, could we live forever and be everywhere like gods? This is the philosophical basis of Ghost in the Shell.
Using a dualistic method to define human beings as consciousness + body comes from Plato. By the time Descartes developed the skepticism that we can only be sure of the existence of consciousness, and that the body and our experiences are logically unverifiable and may be an illusion. I think, therefore I am emphasizing that we can only determine our own existence through thinking (consciousness), and whether the experience of the body is just an illusion and cannot be proved. This is the philosophy that puts consciousness at the heart of human existence. In this Ghost in the Shell, Major's consciousness descended on a puppet robot and instantly became Bart's teammate, bringing the film's climax.
But if the Major returns to the computer network and leaves the body, we cannot imagine what kind of existence she is. When all our consciousness is downloaded to the computer, but this consciousness does not have a corresponding body, we transcend time and space, but also have no foothold, so do we really exist?
Maybe it's just a thought experiment brought on by the movie. Maybe there is no consciousness that is separated from the body, maybe it is a philosophical error to define people as consciousness + body itself...
