From his 1945 essay "The Prevention of Literature:"
Fifteen years ago, when one defended the freedom of the intellect, one had to defend it against Conservatives, against Catholics, and to some extent–for they were not of great importance in England–against Fascists. Today one has to defend it against Communists and "fellow-travelers". One ought not to exaggerate the direct influence of the small English Communist Party, but there can be no question about the poisonous effect of the Russian MYTHOS on English intellectual life. Because of it known facts are suppressed and distorted to such an extent as to make it doubtful whether a true history of our times can ever be written. Let me give just one instance out of the hundreds that could be cited. When Germany collapsed, it was found that very large numbers of Soviet Russians–mostly, no doubt, from non-political motives–had changed sides and were fighting for the Germans. Also, a small but not negligible portion of the Russian prisoners and displaced persons refused to go back to the U.S.S.R., and some of them, at least, were repatriated against their will. These facts, known to many journalists on the spot, went almost unmentioned in the British press, while at the same time Russophile publicists in England continued to justify the purges and deportations of 1936-38 by claiming that the U.S.S.R. "had no quislings". The fog of lies and misinformation that surrounds such subjects as the Ukraine famine, the Spanish civil war, Russian policy in Poland, and so forth, is not due entirely to conscious dishonesty, but any writer or journalist who is fully sympathetic for the U.S.S.R.–sympathetic, that is, in the way the Russians themselves would want him to be–does have to acquiesce in deliberate falsification on important issues. I have before me what must be a very rare pamphlet, written by Maxim Litvinoff in 1918 and outlining the recent events in the Russian Revolution. It makes no mention of Stalin, but gives high praise to Trotsky, and also to Zinoviev, Kamenev, and others. What could be the attitude of even the most intellectually scrupulous Communist towards such a pamphlet? At best, the obscurantist attitude of saying that it is an undesirable document and better suppressed. And if for some reason it were decided to issue a garbled version of the pamphlet, denigrating Trotsky and inserting references to Stalin, no Communist who remained faithful to his party could protest. Forgeries almost as gross as this have been committed in recent years. But the significant thing is not that they happen, but that, even when they are known about, they provoke no reaction from the left-wing intelligentsia as a whole. The argument that to tell the truth would be "inopportune" or would "play into the hands of" somebody or other is felt to be unanswerable, and few people are bothered by the prospect of the lies which they condone getting out of the newspapers and into the history books.
The organized lying practiced by totalitarian states is not, as is sometimes claimed, a temporary expedient of the same nature as military deception. It is something integral to totalitarianism, something that would still continue even if concentration camps and secret police forces had ceased to be necessary. Among intelligent Communists there is an underground legend to the effect that although the Russian government is obliged now to deal in lying propaganda, frame-up trials, and so forth, it is secretly recording the true facts and will publish them at some future time. We can, I believe, be quite certain that this is not the case, because the mentality implied by such an action is that of a liberal historian who believes that the past cannot be altered and that a correct knowledge of history is valuable as a matter of course. From the totalitarian point of view history is something to be created rather than learned. A totalitarian state is in effect a theocracy, and its ruling caste, in order to keep its position, has to be thought of as infallible. But since, in practice, no one is infallible, it is frequently necessary to rearrange past events in order to show that this or that mistake was not made, or that this or that imaginary triumph actually happened. Then again, every major change in policy demands a corresponding change of doctrine and a revelation of prominent historical figures. This kind of thing happens everywhere, but is clearly likelier to lead to outright falsification in societies where only one opinion is permissible at any given moment. Totalitarianism demands, in fact, the continuous alteration of the past, and in the long run probably demands a disbelief in the very existence of objective truth. The friends of totalitarianism in this country usually tend to argue that since absolute truth is not attainable, a big lie is no worse than a little lie. It is pointed out that all historical records are biased and inaccurate, or on the other hand, that modern physics has proven that what seems to us the real world is an illusion, so that to believe in the evidence of one's senses is simply vulgar philistinism. A totalitarian society which succeeded in perpetuating itself would probably set up a schizophrenic system of thought, in which the laws of common sense held good in everyday life and in certain exact sciences, but could be disregarded by the politician, the historian, and the sociologist. Already there are countless people who would think it scandalous to falsify a scientific textbook, but would see nothing wrong in falsifying an historical fact. It is at the point where literature and politics cross that totalitarianism exerts its greatest pressure on the intellectual. The exact sciences are not, at this date, menaced to anything like the same extent. This partly accounts for the fact that in all countries it is easier for the scientists than for the writers to line up behind their respective governments.
