Stephen King says that writing is telepathy. What he means is that I can describe an object, a scene or a person, you can read that, and the image has been transmitted into your mind without my saying anything.
It’s not a perfect metaphor nor is the transmission of thought perfect. It is useful, though. I am trying to get something that lives in my head into your head. The same is true for all art and, for that matter, all forms of communication.
