When Breath Becomes Air

by Paul Kalanithi

You that seek what life is in death, Now find it air that once was breath. New names unknown, old names gone: Till time end bodies, but souls none. Reader! then make time, while you be, But steps to your eternity. —Baron Brooke Fulke Greville, “Caelica 83”

find answers that are not in books, to find a different sort of sublime, to forge relationships with the suffering, and to keep following the question of what makes human life meaningful, even in the face of death and decay.

And as I sat there, I realized that the questions intersecting life, death, and meaning, questions that all people face at some point, usually arise in a medical context. In the actual situations where one encounters these questions, it becomes a necessarily philosophical and biological exercise. Humans are organisms, subject to physical laws, including, alas, the one that says entropy always increases. Diseases are molecules misbehaving; the basic requirement of life is metabolism, and death its cessation.

neurosurgical problem forces a patient and family, ideally with a doctor as a guide, to answer this question: What makes life meaningful enough to go on living?

I had started in this career, in part, to pursue death: to grasp it, uncloak it, and see it eye-to-eye, unblinking. Neurosurgery attracted me as much for its intertwining of brain and consciousness as for its intertwining of life and death. I had thought that a life spent in the space between the two would grant me not merely a stage for compassionate action but an elevation of my own being: getting as far away from petty materialism, from self-important trivia, getting right there, to the heart of the matter, to truly life-and-death decisions and struggles…surely a kind of transcendence would be found there? But in residency, something else was gradually unfolding. In the midst of this endless barrage of head injuries, I began to suspect that being so close to the fiery light of such moments only blinded me to their nature, like trying to learn astronomy by staring directly at the sun. I was not yet with patients in their pivotal moments, I was merely at those pivotal moments. I observed a lot of suffering; worse, I became inured to it. Drowning, even in blood, one adapts, learns to float, to swim, even to enjoy life, bonding with the nurses, doctors, and others who are clinging to the same raft, caught in the same tide.

When there’s no place for the scalpel, words are the surgeon’s only tool.

As a chief resident, nearly all responsibility fell on my shoulders, and the opportunities to succeed—or fail—were greater than ever. The pain of failure had led me to understand that technical excellence was a moral requirement. Good intentions were not enough, not when so much depended on my skills, when the difference between tragedy and triumph was defined by one or two millimeters.

One chapter of my life seemed to have ended; perhaps the whole book was closing. Instead of being the pastoral figure aiding a life transition, I found myself the sheep, lost and confused. Severe illness wasn’t life-altering, it was life-shattering. It felt less like an epiphany—a piercing burst of light, illuminating What Really Matters—and more like someone had just firebombed the path forward. Now I would have to work around it.

I began to realize that coming in such close contact with my own mortality 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.

It occurred to me that my relationship with statistics changed as soon as I became one.

What patients seek is not scientific knowledge that doctors hide but existential authenticity each person must find on her own. Getting too deeply into statistics is like trying to quench a thirst with salty water. The angst of facing mortality has no remedy in probability.

Lost in a featureless wasteland of my own mortality, and finding no traction in the reams of scientific studies, intracellular molecular pathways, and endless curves of survival statistics, I began reading literature again: Solzhenitsyn’s Cancer Ward, B. S. Johnson’s The Unfortunates, Tolstoy’s Ivan Ilyich, Nagel’s Mind and Cosmos, Woolf, Kafka, Montaigne, Frost, Greville, memoirs of cancer patients—anything by anyone who had ever written about mortality.

I woke up in pain, facing another day—no project beyond breakfast seemed tenable. I can’t go on, I thought, and immediately, its antiphon responded, completing Samuel Beckett’s seven words, words I had learned long ago as an undergraduate: I’ll go on. I got out of bed and took a step forward, repeating the phrase over and over: “I can’t go on. I’ll go on.”

The tricky part of illness is that, as you go through it, your values are constantly changing. You try to figure out what matters to you, and then you keep figuring it out. It felt like someone had taken away my credit card and I was having to learn how to budget. You may decide you want to spend your time working as a neurosurgeon, but two months later, you may feel differently. Two months after that, you may want to learn to play the saxophone or devote yourself to the church. Death may be a one-time event, but living with terminal illness is a process.

Science may provide the most useful way to organize empirical, reproducible data, but its power to do so is predicated on its inability to grasp the most central aspects of human life: hope, fear, love, hate, beauty, envy, honor, weakness, striving, suffering, virtue.

Human knowledge is never contained in one person. It grows from the relationships we create between each other and the world, and still it is never complete.

Part of the cruelty of cancer, though, is not only that it limits your time; it also limits your energy, vastly reducing the amount you can squeeze into a day. It is a tired hare who now races. And even if I had the energy, I prefer a more tortoiselike approach. I plod, I ponder. Some days, I simply persist.

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.

When you come to one of the many moments in life where 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. In this time, right now, that is an enormous thing.
