Orwell is discussing the different forms of intellectual hubris; Trotskyism, Irish Nationalists, Communists, Pacifists, Tories, etc. He lumps then all into forms of nationalism which he describes as "the habit of assuming that human beings can be classified like insects and that whole blocks of millions or tens of millions of people can be confidently labeled [sic] "good" or "bad." But secondly -- and this is much more important -- I mean the habit of identifying oneself with a single nation or other unit, placing it beyond good and evil and recognizing no other duty than that of advancing its interests." In contemporary parlance, something more akin to ideology.
He is writing in May 1945, and yet the tenor of ideological commitment is everywhere you turn today - debates about abortion, or gun rights, or capital punishment, or how to best ensure adequate health, etc.. When we ought to be discussing things as respectful individuals, judging on fact and logic, extending tolerance, debates are instead marked by all the issues Orwell raises - isolating the other as evil, engaging with alternative ideas not to test our way towards truth but rather to destroy the enemy, and always, willful blindness to plain realities.
All of these facts are grossly obvious if one's emotions do not happen to be involved: but to the kind of person named in each case they are also intolerable, and so they have to be denied, and false theories constructed upon their denial. I come back to the astonishing failure of military prediction in the present war. It is, I think, true to say that the intelligentsia have been more wrong about the progress of the war than the common people, and that they were more swayed by partisan feelings. The average intellectual of the Left believed, for instance, that the war was lost in 1940, that the Germans were bound to overrun Egypt in 1942, that the Japanese would never be driven out of the lands they had conquered, and that the Anglo-American bombing offensive was making no impression on Germany. He could believe these things because his hatred for the British ruling class forbade him to admit that British plans could succeed. There is no limit to the follies that can be swallowed if one is under the influence of feelings of this kind. I have heard it confidently stated, for instance, that the American troops had been brought to Europe not to fight the Germans but to crush an English revolution. One has to belong to the intelligentsia to believe things like that: no ordinary man could be such a fool. When Hitler invaded Russia, the officials of the MOI issued "as background" a warning that Russia might be expected to collapse in six weeks. On the other hand the Communists regarded every phase of the war as a Russian victory, even when the Russians were driven back almost to the Caspian Sea and had lost several million prisoners. There is no need to multiply instances. The point is that as soon as fear, hatred, jealousy and power worship are involved, the sense of reality becomes unhinged. And, as I have pointed out already, the sense of right and wrong becomes unhinged also. There is no crime, absolutely none, that cannot be condoned when "our" side commits it. Even if one does not deny that the crime has happened, even if one knows that it is exactly the same crime as one has condemned in some other case, even if one admits in an intellectual sense that it is unjustified -- still one cannot feel that it is wrong. Loyalty is involved, and so pity ceases to function.
The reason for the rise and spread of nationalism is far too big a question to be raised here. It is enough to say that, in the forms in which it appears among English intellectuals, it is a distorted reflection of the frightful battles actually happening in the external world, and that its worst follies have been made possible by the breakdown of patriotism and religious belief. If one follows up this train of thought, one is in danger of being led into a species of Conservatism, or into political quietism. It can be plausibly argued, for instance -- it is even possibly true -- that patriotism is an inocculation against nationalism, that monarchy is a guard against dictatorship, and that organized religion is a guard against superstition. Or again, it can be argued that no unbiased outlook is possible, that all creeds and causes involve the same lies, follies, and barbarities; and this is often advanced as a reason for keeping out of politics altogether. I do not accept this argument, if only because in the modern world no one describable as an intellectual can keep out of politics in the sense of not caring about them. I think one must engage in politics -- using the word in a wide sense -- and that one must have preferences: that is, one must recognize that some causes are objectively better than others, even if they are advanced by equally bad means. As for the nationalistic loves and hatreds that I have spoken of, they are part of the make-up of most of us, whether we like it or not. Whether it is possible to get rid of them I do not know, but I do believe that it is possible to struggle against them, and that this is essentially a moral effort. It is a question first of all of discovering what one really is, what one's own feelings really are, and then of making allowance for the inevitable bias. If you hate and fear Russia, if you are jealous of the wealth and power of America, if you despise Jews, if you have a sentiment of inferiority towards the British ruling class, you cannot get rid of those feelings simply by taking thought. But you can at least recognize that you have them, and prevent them from contaminating your mental processes. The emotional urges which are inescapable, and are perhaps even necessary to political action, should be able to exist side by side with an acceptance of reality. But this, I repeat, needs a moral effort, and contemporary English literature, so far as it is alive at all to the major issues of our time, shows how few of us are prepared to make it.
