“He was powerless because he had no precise desire, and this tortured him because he was vainly seeking something to desire. He could not even make himself stretch out his hand to switch on the light. The simple transition from intention to action seemed an unimaginable miracle.”

“Unfortunately his urge to write had suddenly petered out and he did not know what to do with himself. He was not sleepy having slept after dinner. The brandy only added to the nuisance. He was a big heavy man of the hairy sort with a somewhat Beethovenlike face. He had lost his wife in November. He had taught philosophy. He was exceedingly virile. His name was Adam Krug.”

“Just like a man grieving because he has recently lost in his dreams some thing that he had never had in reality, or hoping that tomorrow he would dream that he found it again. That is how mathematics is created; it has its fatal flaw.”

“...If he failed the first time he took his driver's licence test, it was mainly because he started an argument with the examiner in an ill-timed effort to prove that nothing could be more humiliating to a rational creature than being required to encourage the development of a base conditional reflex by stopping at a red light when there was not an earthly soul around, heeled or wheeled. He was more circumspect the next time, and passed...”

“As happens in dreams, when a perfectly harmless object inspires us with fear and thereafter is frightening every time we dream of it (and even in real life retains disquieting overtones), so Dreyer's presence became for Franz a refined torture, an implacable menace. [ ... H]e could not help cringing when, with a banging of doors in a dramatic draft, Martha and Dreyer entered simultaneously from two different rooms as if on a too harshly lit stage. Then he snapped to attention and in this attitude felt himself ascending through the ceiling, through the roof, into the black-brown sky, while, in reality, drained and empty, he was shaking hands with Martha, with Dreyer. He dropped back on his feet out of that dark nonexistence, from those unknown and rather silly heights, to land firmly in the middle of the room (safe, safe!) when hearty Dreyer described a circle with his index finger and jabbed him in the navel; Franz mimicked a gasp and giggled; and as usual Martha was coldly radiant. His fear did not pass but only subsided temporarily: one incautious glance, one eloquent smile, and all would be revealed, and a disaster beyond imagination would shatter his career. Thereafter whenever he entered this house, he imagined that the disaster had happened—that Martha had been found out, or had confessed everything in a fit of insanity or religious self-immolation to her husband; and the drawing room chandelier invariably met him with a sinister refulgence.”

“To each, or about each, of his colleagues he had said at one time or other, something... something impossible to recall in this or that case and difficult to define in general terms -- some careless bright and harsh trifle that had grazed a stretch of raw flesh.”

“Even while writing his book, he had become painfully aware how little he knew his own planet while attempting to piece together another one from jagged bits filched from deranged brains.”
