«Words prepare the way for deeds to come, detonate future explosions. (…) Perhaps we’re already sitting on a powder barrel (…). Look out of the window. There’s the explosive already which will blow up our Accident Insurance and every other institution in the neighbourhood. (…) Your words of abuse today may turn into a universally valid principle of denigration, for words are magical formulae. They leave finger marks behind on the brain, which in the twinkling of an eye become the footprints of history. One ought to watch one’s every word.»
– Kafka, “Conversations with Janouch”.
