The thing that drove Dickens forward into a form of art for which he was not really suited, and at the same time caused us to remember him, was simpl… - George Orwell

The point is that we are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, impudently twisting the facts so as to show that we were right. Intellectually, it is possible to carry on this process for an indefinite time: the only check on it is that sooner or later a false belief bumps up against solid reality, usually on a battlefield.

In past ages, a war, almost by definition, was something that sooner or later came to an end, usually in unmistakable victory or defeat. In the past, also, war was one of the main instruments by which human societies were kept in touch with physical reality. All rulers in all ages have tried to impose a false view of the world upon their followers, but they could not afford to encourage any illusion that tended to impair military efficiency. So long as defeat meant the loss of independence, or some other result generally held to be undesirable, the precautions against defeat had to be serious. Physical facts could not be ignored. In philosophy, or religion, or ethics, or politics, two and two might make five, but when one was designing a gun or an aeroplane they had to make four. Inefficient nations were always conquered sooner or later, and the struggle for efficiency was inimical to illusions. Moreover, to be efficient it was necessary to be able to learn from the past, which meant having a fairly accurate idea of what had happened in the past. Newspapers and history books were, of course, always coloured and biased, but falsification of the kind that is practiced today would have been impossible. War was a sure safeguard of sanity, and so far as the ruling classes were concerned it was probably the most important of all safeguards. While wars could be won or lost, no ruling class could be completely irresponsible.

It was curious to think that the sky was the same for everybody, in Eurasia or Eastasia as well as here. And the people under the sky were also very much the same — everywhere, all over the world, hundreds or thousands of millions of people just like this, people ignorant of one another's existence, held apart by walls of hatred and lies, and yet almost exactly the same — people who had never learned to think but were storing up in their hearts and bellies and muscles the power that would one day overturn the world.
