Getting knocked down by a bus. The experience left me with the exhilaration of life enhanced.

I inadvertently rubbed the milky residue of a toxic cactus plant into my eye while filming Women In Love in the desert in Namibia, and my body went into anaphylactic shock as the producer sped me to a clinic 50 miles away.

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.

Ten years ago, I went to visit my dad in Australia. I walked to the edge of a cliff and looked over and tripped. I righted myself but my head was over the edge. No one saw it.

Everyone succumbs to finitude. I suspect I am not the only one who reaches this pluperfect state. Most ambitions are either achieved or abandoned; either way, they belong to the past. The future, instead of the ladder toward the goals of life, flattens out into a perpetual present. Money, status, all the vanities the preacher of Ecclesiastes described, hold so little interest: a chasing after wind, indeed.

Yet one thing cannot be robbed of her futurity: my daughter, Cady. I hope I’ll live long enough that she has some memory of me. Words have a longevity I do not. I had thought I could leave her a series of letters — but what would they really say? ... There is perhaps only one thing to say to this infant, who is all future, overlapping briefly with me, whose life, barring the improbable, is all but past. That message is simple: When you come to one of the many moments in life when you must give an account of yourself, provide a ledger of what you have been, and done, and meant to the world, do not, I pray, discount that you filled a dying man’s days with a sated joy, a joy unknown to me in all my prior years, a joy that does not hunger for more and more, but rests, satisfied.

I remember the moment when my overwhelming uneasiness yielded. Seven words from Samuel Beckett, a writer I’ve not even read that well, learned long ago as an undergraduate, began to repeat in my head, and the seemingly impassable sea of uncertainty parted: “I can’t go on. I’ll go on.” I took a step forward, repeating the phrase over and over: “I can’t go on. I’ll go on.” And then, at some point, I was through.

I began to realize that coming face to face with my own mortality, in a sense, had changed both nothing and everything. Before my cancer was diagnosed, I knew that someday I would die, but I didn’t know when. After the diagnosis, I knew that someday I would die, but I didn’t know when. But now I knew it acutely. The problem wasn’t really a scientific one. The fact of death is unsettling. Yet there is no other way to live.
