Part of what separates us from the other creatures on earth is that we make up stories. We are storytellers. And we can tell bad stories and we can tell good stories. We can tell stories that lead to division and hate and war. Or we can tell stories that lead to cooperation and peace and progress.

The movement has perfected a rarefied form of America’s addiction to self-rule, which denies much of our humanity: our fragile bodies, our finitude, our need to stare down our deaths (at least once in a while) and be filled with dread and wonder. At some point, we must say to ourselves, I’m going to need to let go.

My generation is on the way out, and each death I have felt as an abruption, a tearing away of part of myself. There will be no one like us when we are gone, but then there is no one like anyone else, ever. When people die, they cannot be replaced. They leave holes that cannot be filled, for it is the fate — the genetic and neural fate — of every human being to be a unique individual, to find his own path, to live his own life, to die his own death.

Nobody wants to be told about the countless minor horrors and humiliations that become facts of “life” when your body turns from being a friend to being a foe: the boring switch from chronic constipation to its sudden dramatic opposite; the equally nasty double cross of feeling acute hunger while fearing even the scent of food; the absolute misery of gut-wringing nausea on an utterly empty stomach; or the pathetic discovery that hair loss extends to the disappearance of the follicles in your nostrils, and thus to the childish and irritating phenomenon of a permanently runny nose. Sorry, but you did ask … It’s no fun to appreciate to the full the truth of the materialist proposition that I don’t have a body, I am a body.

Many readers have informed me that it is a tragic and dreary business to go into death without faith. I don’t feel that way. “Faith” is neutral. All depends on what is believed in. I have no desire to live forever. The concept frightens me. I am 69, have had cancer, will die sooner than most of those reading this. That is in the nature of things.

Thank God I found sobriety. I could sustain myself with my work, my reading, the movies, my friends. And walking, walking, walking. Of all the purposes of education, I think the most useful is this: It prepares you to keep yourself entertained. It gives you a better chance of an interesting job. ... I can't remember the last time I felt bored. I can't eat, drink or talk, and yet I have so many other resources to keep myself entertained. I think I must be a case study.

One of these days I will encounter what Henry James called on his deathbed “the distinguished thing.” I will not be conscious of the moment of passing. In this life I have already been declared dead. It wasn’t so bad. After the first ruptured artery, the doctors thought I was finished. My wife, Chaz, said she sensed that I was still alive and was communicating to her that I wasn’t finished yet. She said our hearts were beating in unison, although my heartbeat couldn’t be discovered. She told the doctors I was alive, they did what doctors do, and here I am, alive.

I know it is coming, and I do not fear it, because I believe there is nothing on the other side of death to fear. I hope to be spared as much pain as possible on the approach path. I was perfectly content before I was born, and I think of death as the same state. I am grateful for the gifts of intelligence, love, wonder and laughter. You can’t say it wasn’t interesting. My lifetime’s memories are what I have brought home from the trip. I will require them for eternity no more than that little souvenir of the Eiffel Tower I brought home from Paris.

I believe that if, at the end, according to our abilities, we have done something to make others a little happier, and something to make ourselves a little happier, that is about the best we can do. To make others less happy is a crime. To make ourselves unhappy is where all crime starts. We must try to contribute joy to the world. That is true no matter what our problems, our health, our circumstances. We must try. I didn’t always know this and am happy I lived long enough to find it out.
