Butlers only truly exist in England

It is sometimes said that butlers only truly exist in England. Other countries, whatever title is actually used, have only manservants. I tend to believe this is true. Continentals are unable to be butlers because they are as a breed incapable of the emotional restraint which only the English race are capable of. Continentals—and by and large the Celts, as you will no doubt agree—are as a rule unable to control themselves in moments of a strong emotion, and are thus unable to maintain a professional demeanour other than in the least challenging of situations. If I may return to my earlier metaphor—you will excuse my putting it so coarsely—they are like a man who will, at the slightest provocation, tear off his suit and his shirt and run about screaming. In a word, “dignity” is beyond such persons. We English have an important advantage over foreigners in this respect and it is for this reason that when you think of a great butler, he is bound, almost by definition, to be an Englishman.
