“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 principle that the end justifies the means is and remains the only rule of political ethics; anything else is just a vague chatter and melts away between one’s fingers.”

“I don't approve of mixing ideologies," Ivanov continued. "There are only two conceptions of human ethics, and they are at opposite poles. One of them is Christian and humane, declares the individual to be sacrosanct, and asserts that the rules of arithmetic are not to be applied to human units. The other starts from the basic principle that a collective aim justifies all means, and not only allows, but demands, that the individual should in every way be subordinated and sacrificed to the community--which may dispose of it as an experimentation rabbit or a sacrificial lamb. The first conception could be called anti-vivisection morality, the second, vivisection morality. Humbugs and dilettantes have always tried to mix the two conceptions; in practice, it is impossible.”

“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.”

“It was quiet in the cell. Rubashov heard only the creaking of his steps on the tiles. Six and a half steps to the door, whence they must come to fetch him, six and a half steps to the window, behind which night was falling. Soon it would be over. But when he asked himself, For what actually are you dying? he found no answer.It was a mistake in the system; perhaps it lay in the precept which until now he had held to be uncontestable, in whose name he had sacrificed others and was himself being sacrificed: in the precept, that the end justifies the means. It was this sentence which had killed the great fraternity of the Revolution and made them run amuck. What had he once written in his diary? "We have thrown overboard all conventions, our sole guiding principle is that of consequent logic; we are sailing without ethical ballast.”

“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.”

“Hitherto man had to live with the idea of death as an individual; from now onward mankind will have to live with the idea of its death as a species.”
