Grad school is subsuming my life, but I came across this definition in the reading for a class I'm hoping to take (*fingers crossed*) on Utopian Science Fiction:
"SF is a literary genre whose necessary and sufficient conditions are the presence and interaction of estrangement and cognition and whose main formal device is an imaginative framework alternative to the author's empirical environment."
-Darko Suvin, "Metamorphoses of Science Fiction."
That would seem to count a lot of fantasy novels as SF, which traditionally upsets the SF hardliners. However, it jives well with my view of the genre and its uses (and pleasures). Thoughts?
