If we only think that parts of him are excellent because parts of him are English, it would be far more sensible to stop at home and possibly enjoy the society of a whole complete Englishman. But anybody who does understand this can take the same pleasure in an American being American that he does in a thunderbolt being swift and a barometer being sensitive. He can see that a vivid sensibility and vigilance really radiate outwards through all the ramifications of machinery and even of materialism. He can see that the American uses his great practical powers upon very small provocation; but he can also see that there is a kind of sense of honour, like that of a duellist, in his readiness to be provoked. Indeed, there is some parallel between the American man of action, however vulgar his aims, and the old feudal idea of the gentleman with a sword at his side. The gentleman may have been proud of being strong or sturdy; he may too often have been proud of being thick-headed; but he was not proud of being thick-skinned. On the contrary, he was proud of being thin-skinned. He also seriously thought that sensitiveness was a part of masculinity. It may be very absurd to read of two Irish gentlemen trying to kill each other for trifles, or of two Irish-American millionaires trying to ruin each other for trash. But the very pettiness of the pretext and even the purpose illustrates the same conception; which may be called the virtue of excitability. And it is really this, and not any rubbish about iron will-power and masterful mentality, that redeems with romance their clockwork cosmos and its industrial ideals. Being a live wire does not mean that the nerves should be like wires; but rather that the very wires should be like nerves.
Another approximation to the truth would be to say that an American is really not ashamed of curiosity. It is not so simple as it looks. Men will carry off curiosity with various kinds of laughter and bravado, just as they will carry off drunkenness or bankruptcy. But very few people are really proud of lying on a door-step, and very few people are really proud of longing to look through a key-hole. I do not speak of looking through it, which involves questions of honour and self-control; but few people feel that even the desire is dignified. Now I fancy the American, at least by comparison with the Englishman, does feel that his curiosity is consistent with his dignity, because dignity is consistent with vivacity. He feels it is not merely the curiosity of Paul Pry, but the curiosity of Christopher Columbus. He is not a spy but an explorer; and he feels his greatness rather grow with his refusal to turn back, as a traveller might feel taller and taller as he neared the source of the Nile or the North-West Passage. Many an Englishman has had that feeling about discoveries in dark continents; but he does not often have it about discoveries in daily life. The one type does believe in the indignity and the other in the dignity of the detective. It has nothing to do with ethics in the merely external sense. It involves no particular comparison in practical morals and manners. It is something in the whole poise and posture of the self; of the way a man carries himself. For men are not only affected by what they are; but still more, when they are fools, by what they think they are; and when they are wise, by what they wish to be.
