"I have fundamental reservations to this adaptation. First of all I would have liked to see the planet Solaris which the director unfortunately denied me as the film was to be a cinematically subdued work. And secondly — as I told Tarkovsky during one of our quarrels — he didn't make Solaris at all, he made Crime and Punishment. What we get in the film is only how this abominable Kelvin has driven poor Harey to suicide and then he has pangs of conscience which are amplified by her appearance; a strange and incomprehensible appearance."

“He who must be what he is, may curse his fate, but cannot change it; on the other hand, he who can transform himself has no one in the world but himself to blame for his failings, no one but himself to hold responsible for his dissatisfaction.”

“The book does not contain "everything about the human being," because that is impossible. The largest libraries in the world do not contain "everything." The quantity of anthropological data discovered by scientists now exceeds any individual's ability to assimilate it. The division of labor, including intellectual labor, begun thirty thousand years ago in the Paleolithic, has become an irreversible phenomenon, and there is nothing that can be done about it. Like it or not, we have placed our destiny in the hands of the experts. A politician is, after all, a kind of expert, if self-styled. Even the fact that competent experts must serve under politicians of mediocre intelligence and little foresight is a problem that we are stuck with, because the experts themselves cannot agree on any major world issue. A logocracy of quarreling experts might be no better than the rule of the mediocrities to which we are subject. The declining intellectual quality of political leadership is the result of the growing complexity of the world. Since no one, be he endowed with the highest wisdom, can grasp it in its entirety, it is those who are least bothered by this who strive for power.”

“Man has gone out to explore other worlds and other civilizations without having explored his own labyrinth of dark passages and secret chambers, and without finding out what lies behind doorways that he himself has sealed.”

“What would happen to us if we could truly sympathize with others, feel with them, suffer for them? The fact that human anguish, fear, and suffering melt away with the death of the individual, that nothing remains of the ascents, the declines, the orgasms, and the agonies, is a praiseworthy gift of evolution, which made us like the animals. If from every unfortunate, from every victim, there remained even a single atom of his feelings, if thus grew the inheritance of the generations, if even a spark could pass from man to man, the world would be full of raw, bowel-torn howling.”

“A smart machine will first consider which is more worth its while: to perform the given task or, instead, to figure some way out of it. Whichever is easier. And why indeed should it behave otherwise, being truly intelligent? For true intelligence demands choice, internal freedom. And therefore we have the malingerants, fudgerators, and drudge-dodgers, not to mention the special phenomenon of simulimbecility or mimicretinism. A mimicretin is a computer that plays stupid in order, once and for all, to be left in peace. And I found out what dissimulators are: they simply pretend that they're not pretending to be defective. Or perhaps it's the other way around. The whole thing is very complicated. A probot is a robot on probation, while a servo is one still serving time. A robotch may or may not be a sabot. One vial, and my head is splitting with information and nomenclature. A confuter, for instance, is not a confounding machine — that's a confutator — but a machine which quotes Confucius. A grammus is an antiquated frammus, a gidget — a cross between a gadget and a widget, usually flighty. A bananalog is an analog banana plug. Contraputers are loners, individualists, unable to work with others; the friction these types used to produce on the grid team led to high revoltage, electrical discharges, even fires. Some get completely out of hand — the dynamoks, the locomoters, the cyberserkers.”
