At that instant the hag's noisy breathing stopped and with it all other sound. Her eyes opened, showing only whites - milky ovals infinitely eerie in the dark root-tangle of her sharp features and stringy hair. The gray tip of her tongue traveled like a large maggot around her lips.

~ Fritz Leiber

What matters is that life is good. It has a lovely texture, like some rich cloth or fur, or the petals of flowers, and everything else worthwhile. And that's as true for the last man as the first.

~ Fritz Leiber

The dark dangerous forest is still there, my friends. Beyond the space of the astronauts and the astronomers, beyond the dark, tangled regions of Freudian and Jungian psychiatry, beyond the dubious psi-realms of Dr. Rhine, beyond the areas policed by the commissars and priests and motivations-research men, far, far beyond the mad, beat, half-hysterical laughter... the utterly unknown still is and the eerie and ghostly lurk, as much wrapped in mystery as ever.

~ Fritz Leiber

The result is ... that there's no room left in the world for the weird – though plenty for crude, contemptuous, wisecracking, fun-poking imitations of it.
