In responding to a story, we react not only with our intellect but with all of ourselves, with our subconscious and our supraconscious selves, the side on the other side of the sun, the side in the dark, the side below the water. And this is something that every writer, no matter how big or how small the talent, must remember. What we have to keep in mind when we write is first and foremost to get on with the story, to keep excitement moving in the reader’s mind.
For instance, if A Wrinkle in Time is not first and foremost an exciting adventure story of time and space, if the fact that while I was writing it I was trying to come to some understanding in myself about good and evil, darkness and light, if that shows too obviously, then I have failed.
