The process of writing is something in which a writer's whole personality plays a part. A writer writes not only with his ideas but also with his instincts, with his intuition. The dark side of a personality also plays a very important role in the process of writing a book. The rational factor is something of which the writer is not totally aware. And so when a writer gives testimony about his books, he does it in a particularly subjective way. He gives a clear picture of only what he wanted to do, which rarely coincides with what he actually did. That is why a reader is sometimes in a better position to judge what a writer has done than the writer himself.
