You know, class is like magic. There's nothing there you can point to, it evaporates if you try to analyse it, but it's real and it affects how people behave and makes things happen.

Jo WaltonI had said that Le Guin's worlds were real because her people were so real, and he said yes, but the people were so real because they were the people the worlds would have produced. If you put Ged to grow up on Anarres or Shevek in Earthsea, they would be the same people, the backgrounds made the people, which of course you see all the time in mainstream fiction, but it's rare in SF.
