“The world of literature is a world where there is no reality except that of the human imagination.”

“The world of reality has its limits; the world of imagination is boundless.”

“There are only two worlds - your world, which is the real world, and other worlds, the fantasy. Worlds like this are worlds of the human imagination: their reality, or lack of reality, is not important. What is important is that they are there. these worlds provide an alternative. Provide an escape. Provide a threat. Provide a dream, and power; provide refuge, and pain. They give your world meaning. They do not exist; and thus they are all that matters. ”

“Literature is where I go to explore the highest and lowest places in human society and in the human spirit, where I hope to find not absolute truth but the truth of the tale, of the imagination and of the heart.”

“The fantastic in literature doesn't exist as a challenge to what is probable, but only there where it can be increased to a challenge of reason itself: the fantastic in literature consists, when all has been said, essentially in showing the world as opaque, as inaccessible to reason on principle. This happens when Piranesi in his imagined prisons depicts a world peopled by other beings than those for which it was created. ("On the Fantastic in Literature")”

“That's really what SF is all about, you know: the big reality that pervades the real world we live in: the reality of change. Science fiction is the very literature of change. In fact, it is the only such literature we have.”
