“The psychological and physiological mechanism of love is so complex that at a certain period in his life a young man must concentrate all his energy on coming to grips with it, and in this way he misses the actual content of the love: the woman he loves. (In this he is much like a young violinist who cannot concentrate on the emotional content of a piece until the technique required to play it comes automatically.)”

“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.”

“It seemed to me an error in reasoning for a man to isolate a woman he loves from all the circumstances in which he met her and in which she lives, to try, with dogged inner concentration, to purify her of everything that is not her self, which is to say also of the story that they lived through together and that gives their ove its shape.After all, what I love in a woman is not what she is in and for herself, but the side of herself she turns toward me, what she is for me. I love her as a character in our common love story.”

“The young man called the waiter and paid. Then he got up and said to the girl: 'We're going.'Where to?' The girl feigned surprise.Don't ask, just come on,' said the young man.Is that any way to talk to me?'It's the way I talk to whores.”

“In the middle of the night, he woke up and realized to his surprise that he had been having one erotic dream after the other. The only one he could recall with any clarity was the last: an enormous naked woman, at least five times his size, floating on her back in a pool, her belly from crotch to navel covered with thick hair. Looking at her from the side of the pool, he was greatly excited. How could he have been excited when his body was debilitated by a gastric disorder? And how could he be excited by the sight of a woman who would have repelled him had he seen her while conscious? He thought: In the clockwork of the head, two cogwheels turn opposite each other. On the one, images; on the other, the body's reactions. The cog carrying the image of a naked woman meshes with the corresponding erection-command cog. But when, for one reason or another, the wheels go out of phase and the excitement cog meshes with a cog bearing the image of a swallow in flight, the penis rises at the sight of a swallow. Moreover, a study by one of Tomas's colleagues, a specialist in human sleep, claimed that during any kind of dream men have erections, which means that the link between erections and naked women is only one of a thousand ways the Creator can set the clockwork moving in a man's head. And what has love in common with all this? Nothing. If a cogwheel in Tomas's head goes out of phase and he is excited by seeing a swallow, it has absolutely no effect on his love for Tereza. If excitement is a mechanism our Creator uses for His own amusement, love is something that belongs to us alone and enables us to flee the Creator. Love is our freedom. Love lies beyond Es muss sein! Though that is not entirely true. Even if love is something other than a clockwork of sex that the Creator uses for His own amusement, it is still attached to it. It is attached to it like a tender naked woman to the pendulum of an enormous clock. Thomas thought: Attaching love to sex is one of the most bizarre ideas the Creator ever had. He also thought: One way of saving love from the stupidity of sex would be to set the clockwork in our head in such a way as to excite us at the sight of a swallow. And with that sweet thought he started dozing off. But on the very threshold of sleep, in the no-man's-land of muddled concepts, he was suddenly certain he had just discovered the solution to all riddles, the key to all mysteries, a new utopia, a paradise: a world where man is excited by seeing a swallow and Tomas can love Tereza without being disturbed by the aggressive stupidity of sex.”

“But was it love? The feeling of wanting to die beside her was clearly exaggerated: he had seen her only once before in his life! Was it simply the hysteria of a man, who, aware deep down of his inaptitude for love, felt the self-deluding need to simulate it?”

“he tried to design his life in such a way that no woman could move in with a suitcase”
