If it is *good* sf the idea is new, it is stimulating, and, probably most important of all, it sets off a chain-reaction of ramification-ideas in the mind of the reader; it so-to-speak unlocks the reader’s mind so that the mind, like the author’s, begins to create. Thus sf is creative and it
inspires creativity, which mainstream fiction by-and-large does not do. We who read sf (I am speaking as a reader now, not a writer) read it because we love to experience this chain-reaction of ideas being set off in our minds by something we read, something with a new idea in it; hence the very best since fiction ultimately winds up being a collaboration between author and reader, in which both create and enjoy doing it: joy is the essential and final ingredient of science fiction, the joy of discovery of newness.
