Perception, Neurology, and Fiction

“Curiouser and curiouser!” cried Alice, (she was so surprised that she quite forgot how to speak good English,) “now I’m opening out like the largest telescope that ever was!

What sets SF apart from non-genre fiction is that it often depicts what we would normally consider a delusion as an accurate reflection of reality.
