In my case, adulthood itself was not an advance, although it was a useful waymark.

Sometimes I'll spend an hour writing a tiny email. I work on it until I've created the illusion that I've dashed it off in three minutes. If I make a typo, I let it stand. Sometimes in fact I correct the typo without thinking, and then I back up and retype the typo so that it'll look more casual. I don't know why.

I certainly felt I had an idea of World War II, and it's probably the idea that many people share: there was this insane aggressor, and there was really only one way to proceed in resisting him. What I didn't realize is that there were many voices belonging to reasonable, interesting, complicated people who had a different way of interpreting the possible responses to the Hitlerian menace.

Churchill was a brilliant and inspiring rhetorician, but one of the first things he did as the head of the British nation was to put German Jews in jail. Tens of thousands of Jews - who had just been fortunate enough to get out from under Hitler only a few years before - spent the entire war in jail.

You almost believe that you will never come to the end of a roll of tape; and when you do, there is a feeling, nearly, though very briefly, of shock and grief.

I would like to visit the factory that makes train horns, and ask them how they are able to arrive at that chord of eternal mournfulness. Is it deliberately sad? Are the horns saying, Be careful, stay away from this train or it will run you over and then people will grieve, and their grief will be as the inconsolable wail of this horn through the night? The out-of-tuneness of the triad is part of its beauty.

Of course, individuals are responsible for individual actions - the pilots who flew over Pearl Harbor and dropped bombs on those ships did a terrible thing as part of an attack on a military base.
