Twenty-five Years (1925)
Context: A friend came to see me on one of the evenings of the last week — he thinks it was on Monday, August 3rd. We were standing at a window of my room in the Foreign Office. It was getting dusk, and the lamps were being lit in the space below... My friend recalls that I remarked on this with the words, "The lamps are going out all over Europe: we shall not see them lit again in our life-time."

Culture
1860s, The Conduct of Life (1860)
Context: I have been quoted as saying captious things about travel; but I mean to do justice. I think, there is a restlessness in our people, which argues want of character. All educated Americans, first or last, go to Europe; — perhaps, because it is their mental home, as the invalid habits of this country might suggest. An eminent teacher of girls said, "the idea of a girl's education, is, whatever qualifies them for going to Europe." Can we never extract this tape-worm of Europe from the brain of our countrymen?

Context: A great change is going on all over the civilized world similar to that infeudation which, in Europe, during the rise of the feudal system, converted free proprietors into vassals, and brought all society into subordination to a hierarchy of wealth and privilege. Whether the new aristocracy is hereditary or not makes little difference. Chance alone may determine who will get the few prizes of a lottery. But it is not the less certain that the vast majority of all who take part in it must draw blanks. The forces of the new era have not yet had time to make status hereditary, but we may clearly see that when the industrial organization compels a thousand workmen to take service under one master, the proportion of masters to men will be but as one to a thousand, though the one may come from the ranks of the thousand. "Master"! We don't like the word. It is not American! But what is the use of objecting to the word when we have the thing? The man who gives me employment, which I must have or suffer, that man is my master, let me call him what I will.
