D.H. Lawrence, I think, defined the difference between writing an article and writing a novel very well. He said, in writing a novel, the writer must be able to identify emotionally and intellectually with two or three or four contradicting perspectives and give each of them very a convincing voice. It's like playing tennis with yourself and you have to be on both sides of the yard. You have to be on both sides, or all sides if there are more than two sides.
