The thing I've been thinking has to do with the audience and the conflict I/we feel between wanting to know "how it's done"--to get behind the scenes and catch-out the "trick"--versus wanting magic to exist, to be a real thing that occurs in the world, to let go of our rational inquiring minds, to feel wonder, to submit.
the psychology of magic and the limits of human perceptions, including this definition of magic from the astounding Teller: “The theatrical linking of a cause with an effect that has no basis in physical reality, but that — in our hearts — ought to.”
The human mind is a mysterious thing--as is the human heart. We want to believe yet we don't want to be fooled. In writing a scene in which magic occurs, I don't have to contend with the laws of time/space/gravity in quite the way that a "real" magician does. After all, in the case of writing, it's all just dots on a page. But what could be more magical that that--creating a whole world built of dots on a page?
