Fictional characters exist in only two places, neither of which is on the printed page. They exist, first, in the mind of the writer and, second, in the mind of the reader.

The need of the human mind for contrast has its roots in the mind's age-old habit of looking for differences and likenesses. When the mind can find no differences and no likenesses, as is the case when monotony is present, it restlessly, then resentfully, and at last frantically seeks for contrast that it may again busy itself with observing differences and likenesses.
