“There are few things in the world that we don't know. Science has explained everything away.”

“...science has "explained" nothing; ...the more we know the more fantastic the world becomes and the profounder the surrounding darkness....”

“Calling it lunacy makes it easier to explain away the things we don't understand.”

“Science is what we understand well enough to explain to a computer; art is everything else.”

“I guess we're all, or most of us, the wards of that nineteenth-century science which denied existence to anything it could not measure or explain. The things we couldn't explain went right on but surely not with our blessing. We did not see what we couldn't explain, and meanwhile a great part of the world was abandoned to children, insane people, fools, and mystics, who were more interested in what is than in why it is. So many old and lovely things are stored in the world's attic, because we don't want them around us and we don't dare throw them out.”

“Science fiction is the arena of the not-yet, and every science fiction story has this element of not-yet-ness — usually a bit of technology or a scientific discovery that we don't know about in the real world of the present but that might be a possibility in the future.”
