G.K. Chesterton (essay, The Defendant(1901) from the chapter, "A Defence of Patriotism":)
......We may imagine that if there were no such thing as a pair of lovers left in the world, all the vocabulary of love might without rebuke be transferred to the lowest and most automatic desire. If no type of chivalrous and purifying passion remained, there would be no one left to say that lust bore none of the marks of love, that lust was rapacious and love pitiful, that lust was blind and love vigilant, that lust sated itself and love was insatiable. So it is with the ' love of the city,' that high and ancient intellectual passion which has been written in red blood on the same table with the primal passions of our being. On all sides we hear to-day of the love of our country, and yet anyone who has literally such a love must be bewildered at the talk, like a man hearing all men say that the moon shines by day and the sun by night. The conviction must come to him at last that these men do not realize what the word ' love' means, that they mean by the love of country, not what a mystic might mean by the love of God, but something of what a child might mean by the love of jam. To one who loves his fatherland, for instance, our boasted indifference to the ethics of a national war is mere mysterious gibberism. It is like telling a man that a boy has committed murder, but that he need not mind because it is only his son. Here clearly the word 'love' is used unmeaningly. It is the essence of love to be sensitive, it is a part of its doom; and anyone who objects to the one must certainly get rid of the other. This sensitiveness, rising sometimes to an'almost morbid sensitiveness, was the mark of all great lovers like Dante and all great patriots like Chatham. 'My country, right or wrong,' is a thing that no patriot would think of saying except in a desperate case. It is like saying, ' My mother, drunk or sober.' No doubt if a decent man's mother took to drink he would share her troubles to the last; but to talk as if he would be in a state of gay indifference as to whether his mother took to drink or not is certainly not the language of men who know the great mystery.
