To see a candle's light, one must take it into a dark place. This is the same as to see the good and be grateful, one must compare and contrast it with something worse - not better!
Ursula K. Le GuinIt did not matter, after all. He was only one man. One man's fate is not important. "If it is not, what is?" He could not endure those remembered words.
Ursula K. Le GuinSci-fi uses the images that sf - starting with H.G. Wells - made familiar: space travel, aliens, galactic wars and federations, time machines, et cetera, taking them literally, not caring if they are possible or even plausible. It has no interest in or relation to real science or technology. It's fantasy in space suits. Spectacle. Wizards with lasers. Kids with ray guns. I've written both, but I have to say I respect science fiction enough that I wince when people call it sci-fi.
