Love and Loss and Grief and More Love: On Self-Help Literature

When I was 21, three weeks after I’d moved to San Francisco to live with my boyfriend Stephen, his lung collapsed on the way to a party. He was casual about it — he had cystic fibrosis, and though he’d only had one health crisis before this moment, he wasn’t surprised. I panicked and went into a coughing fit. The next morning, we headed over to the hospital at UCSF, and began the part of our life together for which there was no map. That evening, home alone, I wandered around our living room. We were sharing an apartment with two of Stephen’s friends, both English majors at Berkeley. I browsed through their books, looking for good end-of-the-night-on-the-day-your-life-has-changed reading. Unlike most of the books I’d brought with me from the University of Chicago, the books on these shelves were written by living authors. (I remember feeling jealous: my roommates had gotten to read these books for school?) I crawled in bed with a book my roommate Steve had raved about, Marilynne Robinson’s Housekeeping. In the morning, I woke up with the light still on, my face pressed into the book’s pages.

Hospital time is funny — both heart-quickening and slow. You know you are at the center of life, that what’s happening right where you are matters, so you feel a constant sense of urgency, and at the same time, the hours themselves are vacation-like, stretching out long, not much to do. In the evenings when I visited Stephen, we’d lie on his bed, talking, watching movies, and reading. He didn’t want to read any of his favorite books in the hospital, on the grounds that they’d carry the aftertaste of the hospital once he got out. He stuck to magazines — the current issue of Rolling Stone, or something football-related. And there’s some truth to his theory — the characters and the landscape of Housekeeping are somehow connected to the hospital in my mind. But the reverse is true too, which was what made it worth reading the book while sitting in a beige chair eating chocolate pudding. The hospital became infused with Housekeeping. I looked forward to diving into its world those evenings. It offered an escape unattainable from a football magazine — or maybe escape is the wrong word — it offered a depth of experience that was part-escape, part-reckoning. The two sisters in its pages, whose mother had died, faced a loss much larger than any I’d ever gone through, but I was dipping my toe in, glimpsing the loss that likely lay in my future. And more, the story evoked a strange state that I was newly experiencing and had no words for — the sudden awareness of how little control I had over life, which left me both at sea and sharpened, helpless and purposeful. That hospital visit, which was longer than expected, I moved from Housekeeping to Beloved to A Personal Matter. And though these three books are so different that their authors might be surprised to see them all appear in the same sentence, they are linked in my mind, for the broad understandings they offered me of suffering and joy, and the complications of love.

After that first health scare, Stephen and I lived a double existence. He was healthy for the most part, and we were kids in our 20s like the rest of our friends, and yet we knew he’d be lucky to live until he was 35, so we were sort of in our 80s, too. It was an unusual existence — no one we knew had gone through it — and you’d think this would have sent me straight to the psychology section, or at least the illness memoir section, of the bookstore where I worked. But the closest I ever got to reading a book that directly addressed my circumstances was when I braved the “issues” shelf in the children’s section, and picked up The Tenth Good Thing about Barney by Judith Viorst, in which a family grieves over the death of their cat. It was partly denial, but it was also the same force that had driven me to fiction since I was kid — I didn’t want to read about my own life. I spent enough time in my own life — I wanted to read about all the lives that I’d never have. Though occasionally, a glimpse of my own life snuck in without my asking. I remember reading The Sheltering Sky, and feeling my stomach drop when the main character dies halfway through the book, and his wife takes over the story. I also remember reading Jack Kerouac Is Pregnant by Aurelie Sheehan, thinking, yes, I know that feeling, Kerouac but tied down, the road trip and the responsibilities all taking place at once.

By the time we were 27, Stephen’s health had begun a dangerous decline. We were living in Cambridge, where he was attending grad school, and we had to admit that we couldn’t pretend to be normal anymore — he needed to quit school and get on the list for a double-lung transplant. At that time, the risks of a transplant were huge, as were the possibilities. If Stephen survived, his lungs would be free of CF for the rest of his life. But the operation was at the cutting edge of modern medicine — half of the people who underwent the surgery died in the first five years. It was a big decision, and we made it together (so sweet, Stephen’s doctor joked, young couples, deciding on everything together — the couch, the kitchen table, the transplant). We packed everything we owned into our 1976 green Volvo and headed back to California to make this next move. This was the first time I ached for nonfiction, for someone who’d been there ahead of me to tell me what to do, or if not that, how to go about living with the unknown. My friend Caitlin was a poet and she gave me Mark Doty’s Heaven’s Coast. I recently looked back in my journal from that time, and there are pages devoted to notes for the letter I planned to write to Doty after reading his book. (I never got around to writing the actual letter.)  Reading them now I feel a little embarrassed. Why would this stranger want to know about all the small and large ways I felt connected to him? And yet I did — more so than I did to the other partners of transplant patients, even to our friends and family who loved me dearly. He’d written intimately about his life with his partner who’d died of AIDS, offering observations that you’d never hear buzzing around a support group, admitting feelings and thoughts I shared but had hardly admitted to myself, much less to Stephen. I was grateful for Heaven’s Coast in a way I can still feel, even though it’s been over 15 years.

Still, in the eye of the storm, when the midnight call for the transplant came, I reached for fiction. Packing hurriedly for the hospital I grabbed Amy Bloom’s Love Invents Us and Ethan Canin’s Blue River. The adrenaline rush of the day of surgery, the euphoria of seeing Stephen breathe with new lungs, it was all mixed up with the stories I read, sitting by his bed. Usually when I read, the story I’m devouring is more dramatic than the events of my own life, but for those weeks, the lives in my books felt calmer and slower than my own, digestible, the authors offering subtle reflections on complicated relationships when there wasn’t room for me to do any reflecting myself. And somehow this allowed me to slow down, too, to sink into the daily events of the transplant a bit. Even if I couldn’t quite reflect, I could observe, and this in itself made the days less harrowing.

I reached for fiction again when Stephen went into the hospital for the last time. I didn’t know it was the last time right away, but he’d landed in the ICU with a ventilator, which was as worrisome as things had ever been. I’d been reading Birds of America by Lorrie Moore, so I brought it along, and sank deep into the stories that first morning, sitting by Stephen’s bed, waiting for him to wake up so we could decide whether we needed to call our families. I read for two hours straight, and kept laughing out loud. A nurse asked me to write down the name of the book for her. She didn’t care what it was about. “If it’s got you laughing in the ICU,” she said, “I have to read it.”

When Stephen died three weeks later, I was reading Platte River by Rick Bass. And while soon I’d read C.S. Lewis’s A Grief Observed, and find deep, specific solace in its pages, I also found solace in Platte River, if less personal, maybe more expansive, too — an acknowledgment of the mysteries in living, of all that we can’t know. It was partly the characters in Platte River, with their bottomless and invisible longings that drew them together and kept them apart, set against the sudden hole in my own life. And it was partly the landscape of Montana, both physically and personally too large for any frame. Montana was the place where my father’s family was from, holding everything I’d never know about his childhood, his parents, why certain family events unfolded the way they did. And its sky and plains were coldly soothing, as endless as the ocean, and offering a similar sort of comfort, with their indifference to my own ups and downs.

Still, when I’m grappling with my life, I reach for fiction. In the years of emerging from grief, of falling in love and marrying again, of having kids and being a part of several families cobbled together, I’ve been up late with The Deptford Trilogy and A Gathering of Old Men, with The Sea, the Sea, and Olive Kitteridge and Sum. I am lost in worlds far from mine, and yet grateful for what they tell me about my own life, too — that it’s only a variation on a theme, that maybe it’s unusual to lose your first husband at 29, but so what — love and loss and grief and more love are out there for all of us, unremarkable in the human scheme of things.

Mind Control: David Eagleman’s Incognito

In the final chapter of his latest book, Incognito: The Secret Lives of the Brain, neuroscientist David Eagleman muses on the ultimate dethronement of humankind, the “fall from the center of ourselves.” Just as Galileo plucked the Earth from the center of the solar system, and Darwin relegated us to one twig among many on the evolutionary tree, a century of modern neuroscience has confirmed Freud’s intuition that the vast majority of brain activity occurs at levels of which the conscious “I” is scarcely even aware—much less in control of.  What we call the conscious mind, Eagleman argues, is far from center stage, and the more we try to find out who—or what—is actually in control of our brain, the more we find out there is, as Gertrude Stein said, “no there there.”

Before he considers the broader implications of our fall from grace, Eagleman spends the first half of the book revealing—through experiments, anecdotes, puzzles, optical illusions, and current events—the extent of the neural wizardry operating behind the conscious curtain of the “I.” It is this wizardry, he suggests, that constructs the cognitive illusion we confidently declare reality. Eagleman, director of the Laboratory for Perception and Action at Baylor College of Medicine, is an agile guide; he is someone who cares about the craft of writing. His bestselling work of fiction, Sum: Forty Tales from the Afterlives, a series of imaginative (if somewhat gimmicky) thought experiments about the possible nature(s) of God, was widely praised when it appeared in 2009. In his latest book, he proves himself, once again. Eagleman presents difficult neuroscience concepts in an energetic, casual voice with plenty of analogies and examples to ensure that what could easily be an overwhelming catalog of facts remains engaging and accessible.

Eagleman uses everyday experiences, familiar to each of us, which reveal the hidden machinations of the brain working in unexpected ways. Even an intuitively effortless act such as seeing, he shows us, is not a passive process of observation, but rather the product of a vast subsurface machinery (by some measures, nearly one-third of the human brain is devoted to vision) that uses an arsenal of assumptions to interpret the ambiguous barrage of shapes and colors that constitute any visual scene. Most readers will fail to appreciate any of these processes until we are shown how often—and how profoundly—we get it totally wrong. For example, the resolution of our peripheral vision is so shockingly poor that if you ask a friend to hold a handful of colored highlighters out to his side while you stare at his nose, you may have the vague sensation of a rainbow in the distance, but might be surprised to discover that you’re unable to name or order any of the colors. Since the brain constantly darts our eyes around so that the high-resolution central vision focuses on whatever it is we are interested in—and therefore anything we are paying attention to appears in sharp focus—the brain assumes the entire visual world is in focus. We think we see what we do not.

What optical illusions really point out is that all of vision is, in a sense, an illusion.

One striking optical illusion, in which a dot on the page disappears as you slowly move the book away from your face, demonstrates that a huge region of vision is in fact missing—due to a quirk of anatomy, we have a sizable blind spot. And yet,  no one noticed this blind spot until its chance discovery in the 17th century because the brain fills in the missing information. It is constantly inventing a patch of reality. The lesson of examples such as these, Eagleman points out, is that “you’re not perceiving what’s out there. You are perceiving whatever your brain tells you.” Whether you are in control of your eyes or your eyes are in control of you is the central, unsettling question posed by these chapters.

The extent to which forces that elude introspection influence not only your perceptions but also your behavior is detailed with increasingly bizarre examples. We find out that a stripper earns higher tips when she is at the most fertile point in her menstrual cycle. People are more likely to marry other people whose names begin with the same letter as their own. Those who are born on February 2nd (2/2) are statistically more likely to live in places like Twin Lakes, Wisconsin; those born on March 3rd in Three Forks, Montana; and those born on June 6th in Six Mile, South Carolina. What these interesting but difficult-to-interpret quirks of human nature reveal is that choices which you happily assign to volition—to free will—may in fact be determined by the alien logic of brain processes inaccessible to the conscious “I.”

But does any of this this matter? Is anything in your life going to change if modern neuroscience strips you of the illusion of free will? Isn’t it just fine to go through the course of the day believing what you see, or ignoring the possibility that arbitrary numbers might influence where you choose to live? Unless you are a philosopher, these issues might seem irrelevant, but Eagleman’s book serves as a clarion call to institutions of law and policy, arguing that they need to be based upon a deeper understanding of ourselves.

As director of the Initiative on Neuroscience and the Law at Baylor University, Eagleman has a thoughtful and considered take on issues of cultural and political power, and his chapter on neuroscience and the law proves to be the strongest in the book. While today’s courts rarely allow such technologies as brain scans into the courtroom, judges may soon deem such scans relevant to arguments about a defendant’s mental state. Many detractors worry moving blame to biology will result in dangerous criminals being exculpated—the “It wasn’t me, it was my brain” defense. Yet the shift is already in motion outside of the courtroom. Most of us believe that diseases such as depression, schizophrenia, and epilepsy have a neurological basis, and that factors such as genes make some of us more susceptible to risky behavioral patterns, such as drug addiction. Similarly, most of us intuitively feel that an Alzheimer’s patient that shoplifts is somehow less guilty of the crime, or that a mentally disabled person who murders should not be sent to prison. How is a legal system that rests on volition and culpability going to address this shifting locus of responsibility?

Eagleman attacks the question head-on:

The heart of the problem is that it no longer makes sense to ask, “To what extent was it his biology and to what extent was it him?” The question no longer makes sense because we now understand those to be the same thing. There is no meaningful distinction between his biology and his decision-making. They are inseparable.

He seeks not to revise the definition of blameworthiness but to remove the concept from jurisprudence altogether. It is true that the more we understand about brain circuitry, the more concepts like indulgence, discipline, and motivation can be explained by biology. It’s also true that if there is a measurable brain problem—such as the case in which a man committed murders due to neurological changes brought on by a brain tumor—the defendant is viewed as less blameworthy. However, a system of jurisprudence in which blame is based upon the state of current technology is not on stable footing; rather than adjusting the definition of blame to suit shifting technology, perhaps we should eschew blame altogether. “Blameworthiness,” Eagleman writes, “is a backward-looking concept that demands the impossible task of untangling the hopelessly complex web of genetics and environment that constructs the trajectory of a human life.” Instead, he hopes that we can leverage findings in neuroscience to better structure the way we punish, ultimately replacing the notion of retribution with either rehabilitation when possible or humane incapacitation when not.

Almost all of the ideas in Eagleman’s book are well-articulated and entertaining, elucidated with the intelligent, casual tone of an enthusiastic university lecturer. However, it’s important to note that, like a lecture, Eagleman’s book does not constitute—nor claim to constitute—original thinking. He has curated examples from the world of modern neuroscience in support of ideas already explored by writers such as Daniel Dennett and Douglas Hoftstadter, or biologists such as Gerald Edelman, packaging them into a highly accessible and energetic work of popular science. Eagleman’s book is rooted firmly in the tradition of scientist-as-explainer, along the lines of Brian Greene’s efforts to bring string theory to a lay audience in The Elegant Universe, or Daniel Levitin’s elucidation of the neuroscience of music in This Is Your Brain On Music.

While we are left, at the end of the book, with the disturbing sensation of wondering who, exactly, it is we are looking at when we look in the mirror, Eagleman assures us that this latest act of dethronement does not leave us disconsolately adrift. Just as astronomy’s revolution invited us to contemplate the gorgeous, vast expanses of the universe, a better understanding of the human brain “tends to open up something bigger than us, ideas more wonderful than we had originally imagined.” Neuroscience can’t weigh in yet on whether or not we house an extrabiological soul, but even if how mind emerges from brain is one day completely described by the laws of classical physics, the threads of causality will be so tangled as to only offer partial insight. So while it is disquieting to ponder the fact that the conscious mind, unaware of the incomprehensible dynamics of multiple neural subsystems blithely chugging away, may be left merely to superimpose meaning on our actions and choices, there is indeed beauty and comfort in knowing that we contain the unknowable.
