Mixing morals with education on dangerousmeta

I don't know how exactly this fits in, but...
I've actually lost most, if not all, respect for the "novel as philosophy" idea. What finally killed it for me was a science fiction book called "The World of Null-A", which is adequately, if a bit breathlessly, summarized and explained here.
What you can't tell from that summary is that the story is clearly subserviant to the philosophy being espoused. What annoyed me finally was the rosy depiction of "null-A" philosophy; it solves all problems, by, basically, dues ex machina.
