There are no laws for the novel. There never have been, nor can there ever be.
I was amazed today to hear that Doris Lessing was just announced as 2007's Nobel Prize winner for literature. I found this amazing first because I thought she was dead and second because apparently she's been writing science fiction for the past few years. Don't get me wrong, I love me some sci-fi, but it's rare to see the genre taken seriously as literature. I hope this signifies a change in its literary reputation. I took a creative writing class once, and the professor announced on the first day that science fiction was not allowed in her class. Really? What if a Nobel laureate was taking your class? Ha!
The thing about Doris Lessing, besides having some interesting short stories and essays, is that she has always been able to come up with these amazing quotes that sum up everything so neatly. Anytime you see a collection of interesting quotes, one of them is usually hers. Her ideas about writing and fiction are just as interesting as her amazingly accurate and sucinct observations about the world around her.
