" They stamp on any change: they close the way and keep the type fixed because they've got the arrogance to think themselves perfect. As they reckon it, they. and only they, are in the true image; very well, then it follows that if the image is true, they themselves must be God: and, being God, they reckon themselves entitled to decree, "thus far, and no farther." That is their great sin: they try to strangle the life out of Life. "
― John Wyndham , The Chrysalids
