"Whatever the scientists may come up with, writers and artists will continue to portray altered mental states, simply because few aspects of our nature fascinate people so much. The so-called mad person will always represent a possible future for every member of the audience - who knows when such a malady may strike?"

If the book is finished—published and on the shelf—I do not think of revising it. But if I'm not finished psychologically with characters, they will recur, either as themselves or as new, slightly altered manifestations, and their same issues will reappear. It's a matter of the subject and emotional investment and my own obsessive thinking about various issues It's an unconscious process. To say that a single story is not done isn't quite true. A story can be finished and judged successful or not by somebody else, but if the issue is not done for me, I can count on its reappearance.
