Part of the particular interest and beauty of science fiction and fantasy: writer and reader collaborate in world-making.
Ursula K. Le GuinIn reading a novel, any novel, we have to know perfectly well that the whole thing is nonsense, and then, while reading, believe every word of it. Finally, when we're done with it, we may find - if it's a good novel - that we're a bit different from what we were before we read it, that we have changed a little... But it's very hard to say just what we learned, how we were changed.
Ursula K. Le GuinA person who believes, as she did, that things fit: that there is a whole of which one is a part, and that in being a part one is whole: such a person has no desire whatever, at any time, to play God. Only those who have denied their being yearn to play at it.
