“To protect himself from the Sirens Ulysses stopped his ears with wax and had himself bound to the mast of his ship. Naturally any and every traveller before him could have done the same, except those whom the Sirens allured even from a great distance; but it was known to all the world that such things were of no help whatever. The song of the Sirens could pierce through everything, and the longing of those they seduced would have broken far stronger bonds than chains and masts. But Ulysses did not think of that, although he had probably heard of it. He trusted absolutely to his handful of wax and his fathom of chain, and in innocent elation over his little stratagem sailed out to meet the Sirens.
Now the Sirens have a still more fatal weapon than their song, namely their silence. And though admittedly such a thing has never happened, still it is conceivable that someone might possibly have escaped from their singing; but from their silence certainly never. Against the feeling of having triumphed over them by one’s own strength, and the consequent exaltation that bears down everything before it, no earthly powers could have remained intact.”
Franz Kafka, The Silence of the Sirens
