What is Science Fiction?
A science fiction story is a story built around human beings, with a human problem, and a human solution, which would not have happened at all without its scientific content.
-Theodore Sturgeon
Science fiction is anything published as science fiction.
-Norman Spinrad
The truth is somewhere between these two positions. The first is probably the view held by most writers and all fans of Science Fiction. Everyone likes to place what they do, or what the love, above that of the works of others. This is not necessarily hubris, but human nature. Science Fiction can and often does bring out the best in its readers by showing them what humans, or aliens, are capable of under extraordinary circumstances.
