There is always an impulse to degrade people who are different from you, to diminish them, to demean them, and it never seems to go away, even when there is ample evidence that when we work together, we do better. It’s not about material progress or personal comfort. It’s about personal identity, and there are still so many forces at work in the human psyche that lead some people to think that their identity requires them to have someone to look down on or to demean or to feel that they’re superior to, and I think that that’s at the root of all this. It’s the only story in human society. Who is the other? Who is one of yours? Cain and Abel.

The problem is I'm older now, I'm 40 years old, and this stuff doesn't change the world. It really doesn't. That's going to break people's hearts. I'm sorry, it's true. Having children really changes your view on these things. We're born, we live for a brief instant, and we die.

I was forced to think very hard about what it meant to be me, what it means to be a person who is only a brain. Pascal's 'thinking reed' really does capture it, because I'm just a bunch of dead muscles thinking.

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.

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.

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.

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.

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.

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.
