“There are things of such darkness and horror—just, I suppose, as there are things of such great beauty—that they will not fit through the puny human doors of perception.”

“Things come in three major degrees in the human experience, I think. There's good, bad, and terrible. And as you go down into progressive darkness towards terrible, it gets harder and harder to make subdivisions.”

“And the most terrifying question of all may be just how much horror the human mind can stand and still maintain a wakeful, staring, unrelenting sanity.”

“The gunslinger said, "I used to think the most terrible thing would be to reach the Dark Tower and find the top room empty. The God of all universes either dead or nonexistent in the first place. But now...suppose there is someone there, Eddie? Someone in charge who turns out to be..." He couldn't finish.Eddie could. "Someone who turns out to be just another bumhug? Is that it? God not dead but feeble-minded and malicious?”

“It's probably wrong to believe there can be any limit to the horror which the human mind can experience. On the contrary, it seems that some exponential effect begins to obtain as deeper and deeper darkness falls-as little as one may like to admit it, human experience tends, in a good many ways, to support the idea that when the nightmare grows black enough, horror spawns horror, one coincidental evil begets other, often more deliberate evils, until finally blackness seems to cover everything. And the most terrifying question of all may be just how much horror the human mind can stand and still maintain a wakeful, staring, unrelenting sanity. That such events have their own Rube Goldberg absurdity goes almost without saying. At some point, it all starts to become rather funny. That may be the point at which sanity begins either to save itself or to buckle and break down; that point at which one's sense of humor begins to reassert itself.”

“Oh, I suppose all men of intelligence know how fragile such things as Law and Justice and Civilization really are, but it's not a thing they think of willingly, because it disturbs one's rest and plays hob with one's appetite.”

“Oh, there were all sorts of things to wonder about, but the truth was simple: here stood this door alone on an endless stretch of beach, and it was for only one of two things: opening or leaving closed.”
