"Whatever is said, the same monotonous noise replies, and quivers up and down the walls until it is absorbed into the roof. "Boum" is the sound as far as the human alphabet can express it, or "bou-oum," or "ou-boum," — utterly dull. Hope, politeness, the blowing of a nose, the squeak of a boot, all produce "boum." Even the striking of a match starts a little worm coiling, which is too small to complete a circle but is eternally watchful. And if several people talk at once, an overlapping howling noise begins, echoes generate echoes, and the cave is stuffed with a snake composed of small snakes, which writhe independently.
The crush and the smells she could forget, but the echo began in some indescribable way to undermine her hold on life. Coming at a moment when she chanced to be fatigued, it had managed to murmur, "Pathos, piety, courage — they exist, but are identical, and so is filth. Everything exists, nothing has value." If one had spoken vileness in that place, or spoken lofty poetry, the comment would have been the same — "ou-boum."
