“Some of the greatest discoveries...consist mainly in the clearing away of psychological roadblocks which obstruct the approach to reality; which is why,post factum they appear so obvious.”

“The more original a discovery, the more obvious it seems afterwards.”

“that man is a reality, mankind an abstraction; that men cannot be treated as units in operations of political arithmetic because they behave like the symbols for zero and the infinite, which dislocate all mathematical operations; that the end justifies the means only within very narrow limits; that ethics is not a function of social utility, and charity not a petty bourgeois sentiment but the gravitational force which keeps civilization in its orbit.”

“The life we led was a proof of man's capacity for adaptation.I think that even the condemned souls in purgatory after time develop a sort of homely routine.That is ,by the way, why most prison memoirs are unreadable.The difficulty of conveying to the reader an idea of a nightmare world from which he has emerged makes the author depict the prisoner's state of mind as an uninterruped continuity of despair.He fears to appear frivolous or to spoil his effect by admitting that even in the depths of misery cheerfulness keeps breaking in.”

“Rubashov had always believed that he knew himself rather well. Being without moral prejudices, he had no illusions about the phenomenon called the "first person singular" and had taken for granted, without particular emotion, that this phenomenon was endowed with certain impulses which people are generally reluctant to admit. Now, when he stood with his forehead against the window or suddenly stopped on the third black tile, he made unexpected discoveries. He found that those processes wrongly known as monologues are really dialogues of a special kind - dialogues in which one partner remains silent while the other, against all grammatical rules, addresses him as "I" instead of "you," in order to creep into his confidence and to fathom his intentions, but the silent partner just remains silent, shuns observation, and even refuses to be localized in time and space.”

“Only once did he remark when the starter,which he was trying to open,literally fell to pieces in his hands,:'If you would write for those filthy boulevard papers,monsieur,you could soon buy a Chevrolet'(which was quite unture:In France the prostitutes of the pen were just as badly rewarded as their colleagues on the street corners).”

“Satan, on the contrary, is thin, ascetic and a fanatical devotee of logic. He reads Machiavelli, Ignatius of Loyola, Marx and Hegel; he is cold and unmerciful to mankind, out of a kind of mathematical mercifulness. He is damned always to do that which is most repugnant to him: to become a slaughterer, in order to abolish slaughtering, to sacrifice lambs so that no more lambs may be slaughtered, to whip people with knouts so that they may learn not to let themselves be whipped, to strip himself of every scruple in the name of a higher scrupulousness, and to challenge the hatred of mankind because of his love for it--an abstract and geometric love.”
