The overall intention may be stated simply enough. Before the Second World War I believed in the perfectibility of social man; that a correct structure of society would produce goodwill; and that therefore you could remove all social ills by a reorganisation of society. It is possible that today I believe something of the same again; but after the war I did not because I was unable to. I had discovered what one man could do to another... I am thinking of the vileness beyond all words that went on, year after year, in the totalitarian states. It is bad enough to say that so many Jews were exterminated in this way and that, so many people liquidated — lovely, elegant word — but there were things done during that period from which I still have to avert my mind less I should be physically sick. They were not done by the headhunters of New Guinea or by some primitive tribe in the Amazon. They were done, skillfully, coldly, by educated men, doctors, lawyers, by men with a tradition of civilization behind them, to beings of their own kind. ...anyone who moved through those years without understanding that man produces evil as a bee produces honey, must have been blind or wrong in the head.
...How did... idealist... socialism turn into Stalinism? How could the political and philosophical idealism of Germany produce... the rule of Adolf Hitler? My own conviction... men were putting the cart before the horse. They were looking at the system rather than the people. ...man’s capacity for greed, his innate cruelty and selfishness was being hidden behind a ...pair of political pants. I believed then, that man was sick — not exceptional man, but average man. ...that the condition of man was to be a morally diseased creation and that the best job I could do ...was to trace the connection between his diseased nature and the international mess he gets himself into. To many... this will seem trite, obvious, and familiar in theological terms. Man is a fallen being. He is gripped by . His nature is sinful and his state is perilous. I accept the theology and admit the triteness; but what is trite is true; and a truism can become more than a truism when it is a belief passionately held.
...I can say here in America what I should not like to say at home; which is that I condemn and detest my country's faults precisely because I am so proud of her many virtues. One of our faults is to believe that evil is somewhere else and inherent in another nation. My book was to say: you think that now the war is over and an evil thing destroyed, you are safe because you are naturally kind and decent. But I know why the thing rose in Germany. I know it could happen in any country. It could happen here.

[Stalin's] purge caused me to examine the meaning of Communism.... I had always known of course that there were books critical of Communism.... I had never read them because I knew that the party did not want me to read them..... the first book I read... was called I Speak for the Silent [by] Professor Vladimir Tchernavin.... He was a little man in the Communist world, gentle, humane, good.... Suddenly for no reason at all he was arrested and carried away by the secret police.... Now for the first time, I believed that slave labor camps existed.... I said ‘this is evil, absolute evil. Of this evil I am a part.’ ... If Communism were evil, what was left but moral chaos? .... The rags that fell from me were not only Communism. What fell was the whole web of the materialist modern mind – the luminous shroud which it has spun about the spirit of man, paralyzing in the name of rationalism the instinct of his soul for God, denying in the name of knowledge the reality of the soul....

I considered the Kremlin capable of any outrage. Its methods by this time seemed to me little better than those of the Nazis, especially in its treatment of its own people and in the forms of organization of power. Reading or listening to anti-Hitler propaganda, I could not help asking myself inwardly, ‘But how does this differ from our Soviet atrocities?’ All the same, I refused to credit the news of a Soviet pact that freed Hitler to make war on Poland and on the rest of Europe. There must be some mistake, I thought, and everyone around me seemed equally incredulous.
