When I was a girl . . . I imagined that life was individual, one's own affair; that the events happening in the world outside were important enough in their own way, but were personally quite irrelevant. Now, like the rest of my generation, I have had to learn again and again the terrible truth . . . that no life is really private, or isolated, or self-sufficient. People's lives were entirely their own, perhaps--and more justifiably--when the world seemed enormous, and all its comings and goings were slow and deliberate. But this is so no longer, and never will be again, since man's inventions have eliminated so much of distance and time; for better, for worse, we are now each of us part of the surge and swell of great economic and political movements, and whatever we do, as individuals or as nations, deeply affects everyone else.
