G.K. Chesterton, “The Patriotic Idea” (from England, a Nation : papers of the Patriot Club.):
This important and growing sect, together with many modern intellectuals of various schools, directly impugn the idea of patriotism as interfering with the larger sentiment of the love of humanity. To them the particular is always the enemy of the general. To them every nation is the rival of mankind. To them, in not a few instances, every man is the rival of mankind.
….
Because the modern intellectuals who disapprove of patriotism do not do this [i.e. celebrate their country], a strange coldness and unreality hangs about their love for men. If you ask them whether they love humanity, they will say, doubtless sincerely, that they do. But if you ask them touching any of the classes that go to make up humanity, you will find that they hate them all. They hate kings, they hate priests, they hate soldiers, they hate sailors. They distrust men of science, they denounce the middle classes, they despair of working men, but they adore humanity. Only they always speak of humanity as if it were a curious foreign nation. They are dividing themselves more and more from men to exalt the strange race of mankind. They are ceasing to be human in the effort to be humane.
The truth is, of course, that real universality is to be reached rather by convincing ourselves that we are in the best possible relation with our immediate surroundings. The man who loves his own children is much more universal, is much more fully in the general order, than the man who dandles the infant hippopotamus or puts the young crocodile in a perambulator. For in loving his own children he is doing something which is (if I may use the phrase) far more essentially hippopotamic than dandling hippopotami ; he is doing as they do. It is the same with patriotism. A man who loves humanity and ignores patriotism is ignoring humanity. The man who loves his country may not happen to pay extravagant verbal compliments to humanity, but he is paying to it the greatest of compliments — imitation.
The fundamental spiritual advantage of patriotism and such sentiments is this : that by means of it all things are loved adequately, because all things are loved individually. Cosmopolitanism gives us one country, and it is good ; nationalism gives us a hundred countries, and every one of them is the best. Cosmopolitanism offers a positive, patriotism a chorus of superlatives. Patriotism begins the praise of the world at the nearest thing, instead of beginning it at the most distant, and thus it insures what is, perhaps, the most essential of all earthly considerations, that nothing upon earth shall go without its due appreciation. Wherever there is a strangely-shaped mountain upon some lonely island, wherever there is a nameless kind of fruit growing in some obscure forest, patriotism insures that this shall not go into darkness without being remembered in a song.
How true.
It is far easier and requires much less care to adore all of humanity than to be devoted to just one, or few, people. The latter requires a deep personal commitment, while the former requires only momentary donations or slogans.
Chesterton also said (in The Napoleon of Notting Hill, I believe): “The patriot never, under any circumstances, boasts of the largeness of his country, but always, and of necessity, boasts of its smallness.” One in the eye for imperial blowhards.
Indeed he did Sir,
Upwards from his abstracted childhood, Adam Wayne had grown strongly and silently in a certain quality or capacity which is in modern cities almost entirely artificial, but which can be natural, and was primarily almost brutally natural in him, the quality or capacity of patriotism. It exists, like other virtues and vices, in a certain undiluted reality. It is not confused with all kinds of other things. A child speaking of his country or his village may make every mistake in Mandeville or tell every lie in Munchausen, but in his statement there will be no psychological lies any more than there can be in a good song. Adam Wayne, as a boy, had for his dull streets in Notting Hill the ultimate and ancient sentiment that went out to Athens or Jerusalem. He knew the secret of the passion, those secrets which make real old national songs sound so strange to our civilisation. He knew that real patriotism tends to sing about sorrows and forlorn hopes much more than about victory. He knew that in proper names themselves is half the poetry of all national poems. Above all, he knew the supreme psychological fact about patriotism, as certain in connection with it as that a fine shame comes to all lovers, the fact that the patriot never under any circumstances boasts of the largeness of his country, but always, and of necessity, boasts of the smallness of it.
