The weaver-god, he weaves; and by that weaving is he deafened, that he hears no mortal voice; and by that humming, we, too, who look on the loom are deafened; and only when we escape it shall we hear the thousand voices that speak through it. For even so it is in all material factories. The spoken words that are inaudible among the flying spindles; those same words are plainly heard without the walls, bursting from the opened casements. Thereby have villainies been detected. Ah, mortal! then, be heedful; for so, in all this din of the great world's loom, thy subtlest thinkings may be overheard afar.
