“A man who loses his privacy loses everything. And a man who gives it up of his own free will is a monster.”

“But the longer a man grows in his own darkness, the more his outer form diminishes”

“That's how it is: even in the throes of death, man is always on stage. And even 'the plainest' of them, the least exhibitionist, because it's not always the man himself who climbs on stage. If he doesn't do it, someone will put him there. That is his fate as a man.”

“In this unity there was happiness, but it is not far from happiness to suspicion, and the girl was full of suspicions. For instance, it occurred to her that other women (those who weren't anxious) were more attractive and more seductive, and that the young man, who did not conceal the fact that he knew this kind of woman well, would someday leave her for a woman like that. (True, the young man declared that he'd had enough of them to last his whole life, but she knew that he was still much younger than he thought.) She wanted him to be completely hers and herself to be completely his, but it often seemed to her that the more she tried to give him everything, the more she denied him something: the very thing that a light and superficial love or a flirtation gives a person.”

“He who gives himself up like a prisoner of war must give up his weapons as well. And deprived in advance of defense against a possible blow, he cannot help wondering when the blow will fall.”

“Speed is the form of ecstasy the technical revolution has bestowed on man. As opposed to a motorcyclist, the runner is always present in his body, forever required to think about his blisters, his exhaustion; when he runs he feels his weight, his age, more conscious than ever of himself and of his time of life. This all changes when man delegates the faculty of speed to a machine: from then on, his own body is outside the process, and he gives over to a speed that is noncorporeal, nonmaterial, pure speed, speed itself, ecstasy speed.”

“...a person who thinks should not try to persuade others to his belief; that is what puts him on the road to a system; on the lamentable road of the "man of conviction"; politicians like to call themselves that; but what is a conviction? It is a thought that has come to a stop, that has congealed, and "the man of conviction" is a man restricted.”
