On his motivations to write Lord of the Flies, from his essay "Fable", p. 85
The Hot Gates (1965)
Context: 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..... but after the war I did not because I was unable to. I had discovered what one man could do to another... I must say that 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... 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.
My own conviction grew that what had happened was that men were putting the cart before the horse. They were looking at the system rather than the people. It seemed to me that man’s capacity for greed, his innate cruelty and selfishness, was being hidden behind a kind of pair of political pants. I believed then, that man was sick — not exceptional man, but average man. I believed that the condition of man was to be a morally diseased creation and that the best job I could do at the time was to trace the connection between his diseased nature and the international mess he gets himself into. To many of you, this will seem trite, obvious, and familiar in theological terms. Man is a fallen being. He is gripped by original sin. 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 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 it could happen in any country. It could happen here.

The Man Without Qualities (1930–1942)
Variant: If there is a sense of reality, there must also be a sense of possibility. To pass freely through open doors, it is necessary to respect the fact that they have solid frames. This principle, by which the old professor had lived, is simply a requisite of the sense of reality. But if there is a sense of reality, and no one will doubt that it has its justifications for existing, then there must also be something we can call a sense of possibility. Whoever has it does not say, for instance: Here this or that has happened, will happen, must happen; but he invents: Here this or that might, could, or ought to happen. If he is told that something is the way it is, he will think: Well, it could probably just as well be otherwise. So the sense of possibility could be defined outright as the ability to conceive of everything there might be just as well, and to attach no more importance to what is than to what is not.

"If God Will Send His Angels"
Lyrics, Pop (1997)
Context: If God will send his angels
I sure could use them here right now
Well if God would send his angels
And I don't have to know how.
