“I think novelists come in two types, and that includes the sort of fledgling novelist I was by 1970. Those who are bound for the more literary or “serious” side of the job examine every possible subject in light of this question: What would writing this sort of story mean to me? Those whose destiny (or ka, if you like) is to include the writing of popular novels are apt to ask a very different one: What would writing this sort of story mean to others? The “serious” novelist is looking for answers and keys to the self; the “popular” novelist is looking for an audience. Both kinds of writer are equally selfish. I’ve known a good many, and will set my watch and warrant upon it.”
