If the purpose of literature is to illuminate human nature, the purpose of fantastic literature is to do that from a wider perspective. You can say different things about what it means to be human if you can contrast that to what it means to be a robot, or an alien, or an elf.
Jo WaltonI sat on the bench by the willows and at my honey bun and read Triton. There are some awful things in the world, itโs true, but there are also some great books. When I grow up I would like to write something that someone could read sitting on a bench on a day that isnโt all that warm and they could sit reading it and totally forget where they were or what time it was so that they were more inside the book than inside their own head. Iโd like to write like Delany or Heinlein or Le Guin.
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.
Jo WaltonAvan was as religious as the next young dragon with his way to make in the world-which is to say that he held many traditional beliefs which he had never paused to examine, attended church because it would have seemed strange not to, rarely paid much attention when he was there, and found piety out of the pulpit thoroughly misplaced.
