What really happens is that the story-maker proves a successful ‘sub-creator’. He makes a Secondary World which your mind can enter. Inside it, what he relates is ‘true’: it accords with the laws of that world. You therefore believe it, while you are, as it were, inside. The moment disbelief arises, the spell is broken; the magic, or rather art, has failed. You are then out in the Primary World again, looking at the little abortive Secondary World from outside.
I love this quote, even though it’s a bit technical. J.R.R. Tolkien (John Ronald Reuel Tolkien) is my favorite author, and if there’s one thing he understood about writing, it was how to create a world. In your writing, you are the master and creator of the world the characters are in. Anything you reveal to the reader about that world is the truth about that world, because you decide what is true for that world. The trick therefore, is to keep this world believable and interesting enough that it can entice readers to enter and accept it. If your world fails in this, the spell, as Tolkien says, is broken.
