“The trouble with science fiction is that you can write about everything: time, space, all the future, all the past, all of the universe, any kind of creature imaginable. That’s too big. It provides no focus for the artist. An artist needs, in order to function, some narrowing of focus. Usually, in the history of art, the narrower the focus in which the artist is forced to work, the greater the art.” – Philip Klass

“Science fiction is what I point at when I say science fiction.” – Damon Knight

“If science fiction is the mythology of modern technology, then its myth is tragic.” – Ursula K. Le Guin

“A science fiction story is a story with a human problem, and a human solution, that would not have happened at all without its scientific content.” – Theodore Sturgeon

“Politicians should read science fiction, not westerns and detective stories.” – Arthur C. Clarke
