I definitely see the good in people. Certainly in my own life I strive to be somebody who is functional and well adjusted and can face conflict in a non-emotional and non-destructive way, and those are the people I try to surround myself with in my life. But as characters, they bore me.
Novels aren't pedagogical instruments, or instructions in law or physics or any other discipline. A novel has to be an emotional experience, a trip of the imagination, and because science has raised so many issues that concern and affect humans, it's a good starting place for me.
