"The twentieth century had dispensed with the formal declaration of war and introduced the fifth column, sabotage, cold war, and war by proxy, but that was only the beginning. Summit meetings for disarmament pursued mutual understanding and a balance of power but were also held to learn the strengths and weaknesses of the enemy. The world of the war-or-peace alternative became a world in which war was peace and peace war."

"The number of one's possible fantasies is inversely proportional to the amount of one's liquid assets. For him who has everything dreams are no longer possible."

"Starożytni mawiali: 'mundus vult decipi, ergo decipiatur'. Świat łaknie oszustw, więc jest oszukiwany."

"A man who for an entire week does nothing but hit himself over the head has little reason to be proud."

"We don't want to conquer the cosmos, we simply want to extend the boundaries of Earth to the frontiers of the cosmos."

"We are only seeking Man. We have no need of other worlds. We need mirrors. We don't know what to do with other worlds. A single world, our own, suffices us; but we can't accept it for what it is. We are searching for an ideal image of our own world: we go in quest of a planet, of a civilisation superior to our own but developed on the basis of a prototype of our primeval past. At the same time, there is something inside us which we don't like to face up to, from which we try to protect ourselves, but which nevertheless remains, since we don't leave Earth in a state of primal innocence. We arrive here as we are in reality, and when the page is turned and that reality is revealed to us — that part of our reality which we would prefer to pass over in silence — then we don't like it any more."

"The fate of a single man can be rich with significance, that of a few hundred less so, but the history of thousands and millions of men does not mean anything at all, in any adequate sense of the word."

"You are only a puppet. But you don't realize that you are."

"He who has had, has been, but he who hasn't been, has been had."

"Come, let us hasten to a higher plane Where dyads tread the fairy fields of Venn, Their indices bedecked from one to n Commingled in an endless Markov chain! I'll grant thee random access to my heart, Thou'lt tell me all the constants of thy love; And so we two shall all love's lemmas prove, And in our bound partition never part. Cancel me not — for what then shall remain? Abscissas, some mantissas, modules, modes, A root or two, a torus and a node: The inverse of my verse, a null domain."

"Take a good look at this world, how riddled it is with huge, gaping holes, how full of Nothingness, the Nothingness that fills the bottomless void between the stars, how everything about us has become lined with it, how it darkly lurks behind each shred of matter. This is your work, envious one! And I hardly think the future generations will bless you for it..."

"Any attempt to understand the motivation of these occurrences is blocked by our own anthropomorphism. Where there are no men, there cannot be motives accessible to men."

"One day Trurl the constructor put together a machine that could build anything beginning with the letter 'n'."

"I hoped for nothing. And yet I lived in expectation. Since she had gone, that was all that remained. I did not know what achievements, what mockery, even what tortures still awaited me. I knew nothing, and I persisted in the faith that the time of cruel miracles was not past."

"To replay human existence — fine, but to replay it in the way a drunk replays a corny tune, pushing coins over and over into the jukebox?"

"The age-old faith of lovers and poets in the power of love, stronger than death, that Finis vitae sed non amoris [Life ends but not love], is a lie, useless and not even funny."

"My past had disappeared. Not that I believed for a moment that this was an accident; in fact, I had suspected for some time now that the Cosmic Command, obviously no longer able to supervise every assignment on an individual basis when there were literally trillions of matters in its charge, had switched over to a random system. The assumption would be that every document, circulating endlessly from desk to desk, must eventually hit upon the right one. A time-consuming procedure, perhaps, but one that would never fail. The Universe itself operated on the same principle. And for an institution as everlasting as the Universe — certainly our Building was such an institution — the speed at which these meanderings and perturbations took place was of no consequence."

"Everything is explicable in the terms of the behavior of a small child."

"Man does not create gods, in spite of appearances. The times, the age, impose them on him. Man can serve his age or rebel against it, but the target of his cooperation or rebellion comes to him from outside."

"In a rocket a person can burst like a bubble, or solidify completely, or boil, or explode in a fountain of blood so quickly he doesn't have time to shout out, and then only his bones will be clattering against the metal, and they'll go on circling in Newtonian orbit with an Einsteinian adjustment, our rattles of progress! And we'll go willingly, because it's a beautiful journey, till we arrive, and in these cabins, over this tableware, amid the immortal dishwashers, with our serried ranks of faithful lockers, our devoted toilets, here is our fulfillment."

"If man had more of a sense of humor, things might have turned out differently."

"Really, one of us ought to have the courage to call the experiment off and shoulder the responsibility for the decision, but the majority reckons that that kind of courage would be a sign of cowardice, and the first step in a retreat. They think it would mean an undignified surrender for mankind — as if there was any dignity in floundering and drowning in what we don't understand and never will."
