SOME people recite history from above, recording the grand deeds of great men. Others tell history from below, arguing that one person's life is just as much a part of mankind's story as another's. If people do make history, as this democratic view suggests, then two people make twice as much history as one. Since there are almost 7 billion people alive today, it follows that they are making seven times as much history as the 1 billion alive in 1811.
