They're talking about things of which they don't have the slightest understanding, anyway. It's only because of their stupidity that they're able to be so sure of themselves.
Franz KafkaI am constantly trying to communicate something incommunicable, to explain something inexplicable, to tell about something I only feel in my bones and which can only be experienced in those bones. Basically it is nothing other than this fear we have so often talked about, but fear spread to everything, fear of the greatest as of the smallest, fear, paralyzing fear of pronouncing a word, although this fear may not only be fear but also a longing for something greater than all that is fearful.
Franz KafkaWhat a fate: to be condemned to work for a firm where the slightest negligence at once gave rise to the gravest suspicion! Were all the employees nothing but a bunch of scoundrels, was there not among them one single loyal devoted man who, had he wasted only an hour or so of the firm's time in the morning, was so tormented by conscience as to be driven out of his mind and actually incapable of leaving his bed?
