I've always felt that death is the greatest invention of life. I'm sure that life evolved without death at first and found that without death, life didn't work very well because it didn't make room for the young. It didn't know how the world was fifty years ago. It didn't know how the world was twenty years ago. It saw it as it is today, without any preconceptions, and dreamed how it could be based on that. We're not satisfied based on the accomplishment of the last thirty years. We're dissatisfied because the current state didn't live up to their ideals. Without death there would be very little progress.

These matters have become discussable with one’s friends, not, of course, as a frequent part of gossip over lunch in the dining room (our only communal occasion) but from time to time, perhaps when admiring someone’s stoicism if their frailty is becoming painfully apparent, or feeling sad at someone else’s inability to accept what seems to be imminent. As a result of this openness, I think that most of the people here would consider it foolish to be frightened of being dead. All of us, however, feel some degree of anxiety about the process of dying.

I’ve had a couple of ex-girlfriends sort of accuse me of having a personality disorder! … No, I don’t know. I’ve always been afraid of death. I’ve never wanted to die. Last year, I watched this guy die in Red Rock. It was this horrible freak accident thing. He fell and he cracked his head and basically just bled out. That was the first time I’d ever actually seen a climbing accident like that. It was kind of sobering — he was even wearing a helmet — it was a reminder of how dangerous climbing can be if things go wrong even when you have all the ropes on.

Somebody who won't go to the doctor for a normal checkup is fearful and nervous. ... But once you find out what it's like on the other side, you can go beyond fear.

It was this celestial splendor that suddenly made me realize how little time, how little life, I had left. My sense of the heavens’ beauty, of eternity, was inseparably mixed for me with a sense of transience — and death. ... I told my friends Kate and Allen, “I would like to see such a sky again when I am dying.” “We’ll wheel you outside,” they said.

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.

The peace of the Sabbath, of a stopped world, a time outside time, was palpable, infused everything, and I found myself drenched with a wistfulness, something akin to nostalgia, wondering what if: What if A and B and C had been different? What sort of person might I have been? What sort of a life might I have lived?

I’ve had this concern all the time, but I can only hope that if one writes with appreciation and delicacy and respect, then it’s okay. I have to say that I’ve written a hundred times as much as I’ve published, because if there’s any thought of offense or embarrassment, then I will put the thing quietly away.

And now, weak, short of breath, my once-firm muscles melted away by cancer, I find my thoughts, increasingly, not on the supernatural or spiritual, but on what is meant by living a good and worthwhile life — achieving a sense of peace within oneself. I find my thoughts drifting to the Sabbath, the day of rest, the seventh day of the week, and perhaps the seventh day of one’s life as well, when one can feel that one’s work is done, and one may, in good conscience, rest.

On the contrary, I feel intensely alive, and I want and hope in the time that remains to deepen my friendships, to say farewell to those I love, to write more, to travel if I have the strength, to achieve new levels of understanding and insight. This will involve audacity, clarity and plain speaking; trying to straighten my accounts with the world. But there will be time, too, for some fun (and even some silliness, as well).
