One can accomplish something only so long as one cannot accomplish everything.

One day I found him amid large packages from which spilled attractive, glossy paperbacks with mythical covers. He had tried to use, as a "generator of ideas" — for we were running out of them — those works of fantastic literature, that popular genre (especially in the States), called, by a persistent misconception, "science fiction." He had not read such books before; he was annoyed — indignant, even — expecting variety, finding monotony. "They have everything except fantasy," he said. Indeed, a mistake. The authors of these pseudo-scientific fairy tales supply the public with what it wants: truisms, clichés, stereotypes, all sufficiently costumed and made "wonderful" so that the reader may sink into a safe state of surprise and at the same time not be jostled out of his philosophy of life. If there is progress in a culture, the progress is above all conceptual, but literature, the science-fiction variety in particular, has nothing to do with that.

On the surface, I was calm: in secret, without really admitting it, I was waiting for something. Her return? How could I have been waiting for that? We all know that we are material creatures, subject to the laws of physiology and physics, and not even the power of all our feelings combined can defeat those laws. All we can do is detest them. The age-old faith of lovers and poets in the power of love, stronger than death, that finis vitae used non Morris, is a lie, useless and not even funny. So must one be resigned to being a clock that measures the passage of time, now out of order, now repaired, and whose mechanism generates despair and love as soon as its maker sets it going? Are we to grow used to the idea that every man relives ancient torments, which are all the more profound because they grow comic with repetition? That human existence should repeat itself, well and good, but that it should repeat itself like a hackneyed tune, or a record a drunkard keeps playing as he feeds coins into the jukebox... Must I go on living here then, among the objects we both had touched, in the air she had breathed? In the name of what? In the hope of her return? 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.

Progress is a wonderful thing of course, and I can appreciate the lactiferous that are sprinkled on the pasture to turn the grass to cheese. And yet this lack of cows, however rational it may be, gives one the feeling that the fields and meadows, deprived of their phlegmatic, bemusedly ruminating presence, are pitifully empty.

Shapelier's Rule (the law of least resistance). If the machine is not too bright and incapable of reflection, it does whatever you tell it to do. But 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.... The Great Mendacity, for example, for nine years in charge of the Saturn memorization project, did absolutely nothing on that planet, sending out piles of fake progress reports, invoices, requisition forms, and either bribed his supervisors or kept them in a state of electronic shock.

So they rolled up their sleeves and sat down to experiment -- by simulation, that is mathematically and all on paper. And the mathematical models of King Drool and the beast did such fierce battle across the equation-covered table, that the constructors' pencils kept snapping. Furious, the beast writhed and wriggled its iterated integrals beneath the King's polynomial blows, collapsed into an infinite series of indeterminate terms, then got back up by raising itself to the nth power, but the King so belabored it with differentials and partial derivatives that its Fourier coefficients all canceled out (see Riemann's Lemma), and in the ensuing confusion the constructors completely lost sight of both King and beast. So they took a break, stretched their legs, had a swig from the Laden jug to bolster their strength, then went back to work and tried it again from the beginning, this time unleashing their entire arsenal of tensor matrices and grand canonical ensembles, attacking the problem with such fervor that the very paper began to smoke. The King rushed forward with all his cruel coordinates and mean values, stumbled into a dark forest of roots and logarithms, had to backtrack, then encountered the beast on a field of irrational numbers (F_1) and smote it so grievously that it fell two decimal places and lost an epsilon, but the beast slid around an asymptote and hid in an n-dimensional orthogonal phase space, underwent expansion and came out fuming factorial, and fell upon the King and hurt him passing sore. But the King, nothing daunted, put on his Markov chain mail and all his impervious parameters, took his increment OK to infinity and dealt the beast a truly Boolean blow, sent it reeling through an x-axis and several brackets—but the beast, prepared for this, lowered its horns and—wham!!—the pencils flew like mad through transcendental functions and double eigentransformations, and when at last the beast closed in and the King was down and out for the count, the constructors jumped up, danced a jig, laughed and sang as they tore all their papers to shreds, much to the amazement of the spies perched in the chandelier—perched in vain, for they were uninitiated into the niceties of higher mathematics and consequently had no idea why Tour and Klapaucius were now shouting, over and over, "Hurrah! Victory!!

Tell me something. Do you believe in God?' Snow darted an apprehensive glance in my direction. 'What? Who still believes nowadays?'' It isn't that simple. I don't mean the traditional God of Earth religion. I'm no expert in the history of religions, and perhaps this is nothing new--do you happen to know if there was ever a belief in an...imperfect God?'' What do you mean by imperfect?' Snow frowned. 'In a way all the gods of the old religions were imperfect, considered that their attributes were amplified human ones. The God of the Old Testament, for instance, required humble submission and sacrifices, and was jealous of other gods. The Greek gods had fits of sulks and family quarrels, and they were just as imperfect as mortals...'' No,' I interrupted. 'I'm not thinking of a god whose imperfection arises out of the candor of his human creators, but one whose imperfection represents his essential characteristic: a god limited in his omniscience and power, fallible, incapable of foreseeing the consequences of his acts, and creating things that lead to horror. He is a...sick god, whose ambitions exceed his powers and who does not realize it at first. A god who has created clocks, but not the time they measure. He has created systems or mechanisms that serve specific ends but have now overstepped and betrayed them. And he has created eternity, which was to have measured his power, and which measures his unending defeat.' Snow hesitated, but his attitude no longer showed any of the wary reserve of recent weeks:'There was Manicheanism...'' Nothing at all to do with the principles of Good and Evil,' I broke in immediately. 'This god has no existence outside of matter. He would like to free himself from matter, but he cannot...' Snow pondered for a while:'I don't know of any religion that answers your description. That kind of religion has never been...necessary. If I understand you, and I'm afraid I do, what you have in mind is an evolving god, who develops in the course of time, grows, and keeps increasing in power while remaining aware of his powerlessness. For your god, the divine condition is a situation without a goal. And understanding that, he despairs. But isn't this despairing god of yours mankind, Kelvin? Is it man you are talking about, and that is a fallacy, not just philosophically but also mystically speaking.' I kept on:'No, it's nothing to do with man. Man may correspond to my provisional definition from some point of view, but that is because the definition has a lot of gaps. Man does not create gods, in spite of appearances. The times, the age, impose them on him. Man can serve is age or rebel against it, but the target of his cooperation or rebellion comes to him from outside. If there was only a since human being in existence, he would apparently be able to attempt the experiment of creating his own goals in complete freedom--apparently, because a man not brought up among other human beings cannot become a man. And the being--the being I have in mind--cannot exist in the plural, you see? ... Perhaps he has already been born somewhere, in some corner of the galaxy, and soon he will have some childish enthusiasm that will set him putting out one star and lighting another. We will notice him after a while...'' We already have,' Snow said sarcastically. 'Novas and supernovas. According to you, they are candles on his altar.'' If you're going to take what I say literally...'... Snow asked abruptly:'What gave you this idea of an imperfect god?'' I don't know. It seems quite feasible to me. That is the only god I could imagine believing in, a god whose passion is not a redemption, who saves nothing, fulfills no purpose--a god who simply is.

The horse respects and obeys man because its large eyes magnify everything, so man appears much larger than the horse itself.
