Une pensée de Orson Scott Card

For science fiction and fantasy are the genre in which stories can hew closest to the archetypes and myths that readers in all time and places have hungered for.

At some point, every science fiction and fantasy story must challenge the reader's experience and learning. That's much of the reason why the genre is so open to experimentation and innovation that other genres reject--strangeness is our bread and butter. Spread it thick or slice it thin, it's still our staff of life.
