With few claims on her time and none on her soul, she turns back outside, into the woods, the green negation of all careers.

The Overstory
By Richard Powers

I read Patricia Westerford's chapter a few months ago and was so moved. Nearly wept. I have thought about it often since. I packed the book for my train ride to Montreal last month, in hopes of advancing with the story during the 11-hour trip. Instead, I re-read her chapter and it produced the same effect. Love.

"She becomes her father's star and only pupil for the simple reason that she alone, of all the family, sees what he knows: plants are willful and crafty and after something, just like people. He tells her, on their drives, about all the oblique miracles that green can devise. People have no corner on curious behavior. Other creatures—bigger, slower, older, more durable—call the shots, make the weather, feed creation, and create the very air.
"It's a great idea, trees. So great that evolution keeps inventing it, again and again."
(p. 114)

"Watching the man, hard-of-hearing, hard-of-speech Patty learns that real joy consists of knowing that human wisdom counts less than the shimmer of beeches in a breeze. As certain as weather coming from the west, the things people know for sure will change. There is no knowing for a fact. The only dependable things are humility and looking."
(p. 115)

"Sophomore year, Patty gets a job in the campus greenhouses—two hours stolen every morning before classes. Genetics, plant physiology, and organic chemistry take her through evening. She studies every night at her carrel until the library closes. Then she reads for pleasure until she falls asleep. She does try the books her friends are reading: Siddhartha, Naked Lunch, On the Road. But nothing else moves her more than Peattie's Natural Histories, books from her father's shelves. Now they're her endless refreshment. The phrases branch and turn to catch the sun."
(p. 120)

"With few claims on her time and none on her soul, she turns back outside, into the woods, the green negation of all careers. She no longer theorizes or speculates. Just watches, notes, and sketches into a stack of notebooks, her only persistent possessions aside from clothes. Her eyes go near and narrow. She camps out many nights with Muir, under the spruce and fir, completely lost, turned wildly around by the smell of inland oceans, sleeping on beds of thick lichen, sixteen inches of brown needle pillow, the living earth beneath her bag, its fluid influence rising up into the fiber of her and all the towering trunks that surround and watch over. The particle of her private self rejoins everything it has been split off from—the plan of runaway green. I only went out for a walk and finally concluded to stay out till sundown, for going out, I found, was really going in.
(p. 129)

"Her public reputation, like Demeter's daughter, crawls back up from the underworld. A scattering of scientific papers vindicates her original work in airborne semaphores. Young researchers find supporting evidence, in species after species. Acacias alert other acacias to prowling giraffes. Willows, poplars, alders: all are caught warning each other of insect invasion across the open air. It makes no difference, her rehabilitation. She doesn't much care what happens, outside this forest. All the world she needs is here, under this canopy—the densest biomass anywhere on Earth."
(p. 141)

This is where I lose it.
"But I'd want to sign the papers." He peers out into an opening in the western firs, where the sun has undeniably started to set. "Because then, when I die, you could get the pension."
(p. 144)

Who makes the world?



Watchmen
By Alan Moore and Dave Gibbons

I re-read Watchmen in honor of HBO's homage debuting later this month.

It was exciting to re-experience its magic and to make new observations that deepened my appreciation for Moore and Gibbons' great, clever, deeply human storytelling.

If I had more time I'd elaborate—but for now will say: still stunning.

Everything In Its Place: First Loves and Last Tales
By Oliver Sacks

Admired Oliver Sacks' compassion towards his patients and his devotion to science, especially neurology. He also had such vast curiosity and enthusiasm about life. From his love of swimming, reading, and nature, to his descriptions of awe-filled, strange, lovely experiences including attending an annual herring festival in NYC, meeting an orangutan for the first time, and more—I loved reading about his adventures and perspectives. He lived life openly, intelligently, fully.

"Mr. Q was another patient, less demented than Dr. M., who resided in a nursing home run by the Little Sisters of the Poor where I often worked. He had been employed for many years as the janitor at a boarding school and now found himself in a somewhat similar place: an institutional building with institutional furniture and a great many people coming and going, especially in the daytime, some in authority, and dressed accordingly, others under their guidance; there was also a strict curriculum, with fixed mealtimes and fixed times for getting up and going to bed. So perhaps it was not entirely unexpected that Mr. Q should imagine that he was still a janitor, still at a school (albeit a school that had undergone some puzzling changes). But if the pupils were sometimes bedridden or elderly, and the staff wore the white habits of a religious order, these were mere details—he never bothered with administrative matters.
He had his job: checking the windows and doors to make sure they were securely locked at night, inspecting the laundry and boiler room to make sure all was functioning smoothly. The sisters who ran the home, though perceiving his confusion and delusion, respected and even reinforced the identity of this somewhat demented resident, who, they felt, might fall apart if it were taken away. So they encouraged him in his janitorial role, giving him keys to certain closets and encouraging him to lock up at night before he retired. He wore a bunch of keys jangling at his waist—the insignia of his office, his official identity. He would check the kitchen to make sure all of the gas rings and stoves were turned off and no perishable food had been left unrefrigerated. And though he slowly became more and more demented over the years, he seemed to be organized and held together in a remarkable way by his role, the varied tasks of checking, cleaning, and maintenance that he performed throughout the day. When Mr. Q died of a sudden heart attack, he did so without perhaps ever realizing that he had been anything but a janitor with a lifetime of loyal work behind him.
Should we have told Mr. Q that he was no longer a janitor but a declining and demented patient in a nursing home? Should we have taken away his accustomed and well-rehearsed identity and replaced it with a "reality" that, though real to us, would have been meaningless to him? It seemed not only pointless but cruel to do so—and might well have hastened his decline."
("Telling," pp. 142-3)

"If the brain is to stay healthy, it must remain active, wondering, playing, exploring, and experimenting right to the end. Such activities or dispositions may not show up on a functional brain imaging or, for that matter, on neuropsychological tests, but they are of the essence in defining the health of the brain and in allowing its development throughout life."
("The Aging Brain," pp. 153)

"The two preeminent evolutionary changes in the early history of life on Earth—from prokaryote to eukaryote, from anaerobe to aerobe—took the better part of two billion years. And then another thousand million years had to pass before life rose above the microscopic and the first multicellular organisms appeared. So if the Earth's history is anything to go by, one should not expect to find any higher life on a planet that is still young. Even if life has appeared and all goes well, it could take billions of years for evolutionary processes to move it along to the multicellular stage."
("Anybody Out There?," pp. 206-7)

"For myself, since I cannot wait, I turn to science fiction on occasion—and, not least, back to my favorite Wells. Although it was written a hundred years ago, "A Lunar Morning"* has the freshness of a new dawn, and it remains for me, as when I first read it, the most poetic evocation of how it may be when, finally, we encounter alien life."
("Anybody Out There?," p. 210)

"Reading is a hugely complex task, one that calls upon many parts of the brain, but it is not a skill humans have acquired through evolution (unlike speech, which is largely hardwired). Reading is a relatively recent development, arising perhaps five thousand years ago, and it depends on a tiny area of the brain's visual cortex. What we now call the visual word form area is part of a cortical region near the back of the left side of the brain that evolved to recognize basic shapes in nature but can be redeployed for the recognition of letters or words. This elementary shape or letter recognition is only the first step.
From this visual word form area, two-way connections must be made to many other parts of the brain, including those responsible for grammar, memories, association, and feelings, so that letters and words acquire their particular meanings for us. We each form unique neural pathways associated with reading, and we each bring to the act of reading a unique combination not only of memory and experience, but of sensory modalities, too. Some people may "hear" the sounds of the words as they read (I do, but only if I am reading for pleasure, not when I am reading for information); others may visualize them, consciously or not. Some may be acutely aware of the acoustic rhythms or emphases of a sentence; others are more aware of its look or its shape."
("Reading the Fine Print," pp. 230-1)


*"Imagine it; Imagine that dawn!"

At the library I felt free—free to look at the thousands, tens of thousands, of books; free to roam and to enjoy the special atmosphere and the quiet companionship of other readers, all like myself, on quests of their own.

Everything In Its Place: First Loves and Last Tales
By Oliver Sacks

"Swimming became a dominant passion at Oxford, and after this there was no going back. When I came to New York, in the mid-1960s, I started to swim at Orchard Beach in the Bronx, and would sometimes make the circuit of City Island—a swim that took me several hours. This, indeed, is how I found the house I lived in for twenty years: I had stopped about halfway around to look at a charming gazebo by the water's edge, got out and strolled up the street, saw a little red house for sale, was shown round it (still dripping) by the puzzled owners, walked along to the real estate agent and convinced her of my interest (she was not used to customers in swim trunks), reentered the water on the other side of the island, and swam back to Orchard Beach, having acquired a house in midswim."
("Water Babies," p. 5)

"I do not think my experience is unique. Many scientists, no less than poets or artists, have a living relation to the past, not just an abstract sense of history and tradition but a feeling of companions and predecessors, ancestors with whom they enjoy a sort of implicit dialogue. Science sometimes sees itself as impersonal, as "pure thought," independent of its historical and human origins. It is often taught as if this were the case. But science is a human enterprise through and through, an organic, evolving, human growth, with sudden spurts and arrests, and strange deviations, too. It grows out of its past but never outgrows it, any more than we outgrow our childhoods."
("Humphry Davy: Poet of Chemistry," p. 39)

"The oak-paneled library was the quietest and most beautiful room in the house, to my eyes, and it vied with my little chemistry lab as my favorite place to be. I would curl up in a chair and become so absorbed in what I was reading that all sense of time would be lost. Whenever I was late for lunch or dinner I could be found, completely enthralled by a book, in the library. I learned to read early, at three our four, and books, and our library, are among my first memories.
But the ur-library, for me, was our local public library, the Willesden library. There I spent many of the happiest hours of my growing-up years—our house was a five-minute walk from the library—and it was there I received my education.
On the whole, I disliked school, sitting in class, receiving instruction; information seemed to go in one ear and out the other. I could not be passive—I had to be active, learn for myself, learn what I wanted, and in the way that suited me best. I was not a good pupil, but I was a good learner, and in the Willesden library—and all the libraries that came later—I roamed the shelves and stacks, had the freedom to select whatever I wanted, to follow paths that fascinated me, to become myself. At the library I felt free—free to look at the thousands, tens of thousands, of books; free to roam and to enjoy the special atmosphere and the quiet companionship of other readers, all like myself, on quests of their own."

It would be fatalistic to think that we are powerless.



What Unites Us: Reflections on Patriotism
By Dan Rather & Elliot Kirschner

At 86 years old, with more than six decades' experience as a journalist, Dan Rather has lived the life I hoped to have when I decided I wanted to be a journalist—a life that's allowed his curiosity to guide him to places all over the country and world. As a result, he possesses great knowledge and is extremely optimistic—two qualities I appreciate and admire. He's also from Houston, which he mentions often; it's a city I've become more interested in [politically, especially] now that my mom lives here. And because it's now become the most diverse city in America and a glimpse of our country's future.

Each section and chapter evaluate topics that matter to me and I loved reading his perspective on them all: Freedom (The Vote, Dissent, The Press), Community (Inclusion, Empathy, Immigration), Exploration (Science, Books, The Arts), Responsibility (The Environment, Public Education, Service), and Character (Audacity, Steady, Courage).

"Amid all this, one truth cannot be ignored: The Detroit public schools are almost entirely African American, and the schools in the surrounding suburbs are overwhelmingly white. This is not an accident. In 1974, the Supreme Court heard a case that centered on Detroit's schools, both in the city and in the surrounding communities. In Milliken v. Bradley the court ruled in a 5-4 decision that a metropolis could in essence be segregated along district lines, just not within those districts. In other words, it was okay if there were real racial divisions, lines of exclusion, between suburbs and cities. And that is the system we largely have today. When you hear the term "inner-city schools," close your eyes and picture the student body. Now picture a suburban school. I am pretty sure that race was part of your mental image. This is not a mirage. Recent governmental and academic studies have shown increased de facto school segregation in the last few decades. In a blistering dissent to the Milliken decision, the first African American justice on the Supreme Court, Thurgood Marshall, predicted our current reality: "School district lines, however innocently drawn, will surely be perceived as fences to separate the races." We have become a less inclusive nation as a result."
("Inclusion," pp. 83-4)

"What sticks with me more than even that act of kindness was how my mother talked to me about it. I was an inquisitive child (perhaps not surprising considering my later path in life), and I was always asking questions. So I asked my mother why we gave those families gifts at Christmas when we ourselves didn't have much. I remember then answering for myself: "It was because we felt sorry for them, right?"
"We do not feel sorry for them," my mother said sternly. "We understand how they feel." It was a lesson that is so seared in my mind, I can see her face and I can hear her tone of voice as if it were yesterday.
What my family did was not heroic. I like to think of it more as neighborly. And it was in line with a national ethos in those dark days, repeated countless times in countless communities across the country. We understood that those who were suffering weren't lazy or lacking the desire to do better. Fate had the potential to slap any of us."
("Empathy," pp. 95-6)

"These states are two of the most marvelous and welcoming in our nation. Their natural wonders are matched only by the friendliness of their inhabitants, and I have enjoyed my time in both immensely. But when you look at the demographic trends of the United States, Alaska is more a throwback to the past, and Hawaii a glimpse of the future. We are destined to look and live more like Hawaii, a multiethnic society where racial lines are blurred through intermarriage, and cultural heritages combine into a new America. Even my hometown of Houston is now one of the most ethnically diverse cities in the country.
Today we see an eagerness among some of our elected officials—buoyed by passionate segments of the voting public—to erect new barriers to immigration. But these efforts will not stop the demographic momentum already underway in the United States. If anything, I believe that demonizing the most recent arrivals to our shores will only, over time, galvanize the political will of the majority of Americans who understand the true legacy of our history.
When I walk around this great land, in small towns and big cities, bus stations and airports, baseball stadiums and art museums, I see an America that has expanded beyond the wildest dreams of its founders. We are a people of energy and purpose, a blended land of ever-increasing diversity that so far has proven the strength and wisdom of our great experiment. We must find a way to defeat the forces of intolerance. If we do, we will emerge a better, stronger nation."
("Immigration," pp. 120-1)

"I believe the public is hungry for better science reporting; it has been my experience that people of all backgrounds tend to be naturally curious and eager for knowledge about their world and the place in it. Several years ago, I did a report on neuroplasticity, the ability of our brains to keep changing even as we age. We included an interview with Nobel Prize-winning scientist Eric Kandel, who helped pioneer the field, and his mind, keen and imaginative well into his eighties, seemed to be living proof of his discoveries. We also interviewed the Dalai Lama. It turns out His Holiness is a science enthusiast, and we learned that researchers studying Buddhist monks have discovered that their deep meditations actually alter the structure of their brains. We got a wonderful response to the program, but one viewer's email stood out. It came from a woman from Oklahoma whose job it was to work heavy construction on highway repairs. This is not the demographic that news executives think would be interested in a subtle examination of neuroplasticity, but this woman was effusive about how much she had learned. She ended her appreciative note with a phrase that has stuck with me ever since: "I always knew my mind could grow.""
("Science," pp. 132-3)

"But while the library's physical charm was impressive, it was what was inside that made it truly magical. I was a voracious reader and spent countless hours in what became a sort of second home. I was following, in my own small way, the path laid out by Jefferson, Carnegie, and all the others who believed in the power of books. And I had a wonderful guide, the librarian Jimmie May Hicks, who served at the Heights branch library from the year of my birth, 1931, until her death in 1964—more than three decades of quiet but consequential service to her community and nation. Like all the best librarians, Ms. Hicks would suggest, question, and prod my reading into new and unexpected directions. The library now has a memorial plaque in her honor that reads, in part, She dedicated her life to her profession and sought always to impart to others joy in acquiring knowledge and pleasure in the art of reading. She was a true patriot."
("Books," p. 147)

We also owned encyclopedias and I remember how special and exciting it was to look up anything I wanted to learn more about. Pre-internet days!
"The importance of curated knowledge was encouraged at home as well. During my last year of elementary school, our principal called in all the parents to prepare them for the challenges of junior high. She talked about not only the looming physical changes of adolescence but also the mental growth that would be required for us to thrive in a more rigorous and less protective academic environment. My mother was a good listener, and she came back determined that what the Rather household needed now more than anything was our own set of encyclopedias. This caused a bit of a disagreement with my father, who insisted this was a luxury we couldn't afford. But my mother insisted that if we bought them on an installment plan, we could make it work. Ultimately, she prevailed with the winning argument that "just having them in the house will help Danny" (and my younger brother, Don, and sister, Patricia).
When boxes packed with the many volumes of the World Book Encyclopedia arrived at our doorstep, it was a momentous day. If memory serves me correctly, we had the choice of ordering the set with either red or blue on the spines and my mother chose red because she felt it would stand out more on the shelves. The books were wonderfully bound and you could feel the weight of knowledge simply by opening them up in your lap and flipping through the pages. My mother was right; just having those books on our shelves transformed our home. Whenever any of us had a question, there was the promise of an answer, and an excuse for more learning."
("Books," pp. 147-8)

"These days it is easier to occupy young minds with mobile phones and tablet computers, but I have a special respect for the mothers and fathers who continue to lug around the bags of crayons, markers, and paper. It brings a smile to my face when I see a child drawing. And while I know there are museum- and concertgoers who are irritated by sharing the spaces with sometimes unruly children, I am encouraged when I see generations of the future engaging with the arts. These pursuits are central to our American identity. Patriotism can burst to the surface through many geysers of expression."
("The Arts," p. 155)

"When I met Jean, we were in our early twenties and she had an enthusiastic thirst for the arts. She loved to paint and go to art exhibits. I wanted to impress her, so on our second date I took her to the Alley Theatre, which has since become one of Houston's most cherished institutions. The Alley was the brainchild of Nina Vance, who gained a national reputation for proving that a town like Houston could handle serious works for the stage. The play Jean and I saw that night was The Glass Menagerie by Tennessee Williams. I was transfixed by the production onstage, and by my date sitting next to me. I knew I wanted to accompany Jean on a lifetime of performances, and over our six decades of marriage, we have done that."
("The Arts, p. 158)

"Our art has been, like our country, boisterous and courageous and gloriously distinct. It has expressed euphoria, shame, and outrage. It has been exalted and it has felt the sting of suppression and marginalization. It has been misunderstood. Perhaps most important, our art has been wonderfully diverse. Our corporate boardrooms do not represent America; neither does our Congress, Supreme Court, nor certainly those we have elected to the presidency. But our artistic community represents the United States in all its multiple wonders.
Any list of great American artists would be woefully incomplete if it did not celebrate the broad democratic stirrings of a diverse nation. Consider one idiosyncratic sampling: Louis Armstrong and Mark Twain and Martha Graham, Emily Dickinson and Ella Fitzgerald and Edward Hopper, William Faulkner and Andy Warhol and Bob Dylan, Langston Hughes and Jackson Pollock and Charlie Chaplin, Johnny Cash and Georgia O'Keeffe and Frank Lloyd Wright, Miles Davis and Willa Cather and Ansel Adams, Willie Nelson and Maya Angelou and Martin Scorsese, George Gershwin and Marlon Brando and Prince, Elvis Presley and Carlos Santana and Stephen Sondheim, Maria Tallchief and Robin Williams and Ernest Hemingway. The list could go on and on. American art is proof that people from all backgrounds and corners of this country have something important to say."
("The Arts," pp. 160-1)

"Nature wasn't something that you drove to, or planned on seeing, or for which you bought a fancy outdoor wardrobe. I worry now that it is an activity that must compete with soccer practices, homework, piano lessons, and all the other responsibilities that fill up the calendar of a family with children. All those are surely wonderful and rewarding, but so too is just letting your legs wander through the trees and meadows, and having your mind wander as well.
Today most of us encounter few animals and plants in our daily lives, and most of what we do see are either the ones we have domesticated or the vermin and weeds that can thrive in the cracks of modernity. Growing up I was enthralled by the night sky. But now most of us can see only a few faint stars at night, the ones bright enough to make it through the domes of light that enclose our metropolises. For all of human history, the night sky told stories, delineated time, and guided voyagers. Now 30 percent of the people on the planet can't even see the Milky Way from their homes. And in the United States, 80 percent of us can't."
("The Environment," p. 184)

"Despite all these injustices, I still had the sense for most of my early career that by and large public education was on a steady march of progress, fueled by a spirit of bipartisan support. Recently I have begun to despair, as I see the very notion of public schools under threat. Instead of a national will to make free and open education a priority and strength, I see insidious forces overtly and covertly undermining our public schools.
The crisis of our schools, especially public schools, is complex. And difficult questions abound: Does the general school tax system need to be reevaluated or not? How do we assess the impact of charter schools, and are some voucher systems worthy of consideration? What about Wall Street's increasing involvement in for-profit schools? What is the optimum role for teachers' unions? The list goes on. But there should be no dispute that if American schools don't improve, America will lose its world leadership. And I believe that whatever system emerges in the future, it must hew to our ideals of public education; It must be open to all, free of charge, and of the highest quality."
("Public Education," pp. 200-1)

"How many politicians could you imagine approaching their accomplishments with this level of humility, especially among our current leaders? That is the benefit of service: It tends to humanize you. People can disagree politically and philosophically on all the issues that confront our nation, but if more of our elected officials had served in causes other than their own advancement, I believe they would approach their jobs with less certainty in their own assumptions and more sympathy for the needs of others. It matters less whether it's in the military, the Peace Corps, the many programs of AmeriCorps, social services, or legal aid. It's about the values that drive a person to help by joining a mission that is bigger than they are."
("Service," p. 222)

"It is difficult for a young boy to remain still in bed when the sun is shining and the world seems to be passing him by outside his bedroom window. I sometimes whimpered at the injustice of my fate, and my father would come into my room to stand over me, lovingly but firmly. "Steady, Danny," he would say. "Steady." The words were clear and deliberate, and they were soothing. At the time, I was too young to fully absorb his simple lesson."
("Steady," p. 248)

"However, it would be fatalistic to think that we are powerless. Maybe we cannot change the equation at the level of the universe, but life is about creating order out of chaos. In the natural world, cells come together to form complex living beings. That's pretty orderly, and inspirational. And we can do something similar by bringing order to our own lives for the betterment of our community."
("Courage," p. 266)

But I always thought it was strange, if our mother cells done so much for medicine, how come her family can't afford to see no doctors?

The Immortal Life of Henrietta Lacks
By Rebecca Skloot

"Deborah [Lack's] Voice

When people ask—and seems like people always be askin to where I can't never get away from it—I say, Yeah, that's right, my mother name was Henrietta Lacks, she died in 1951, John Hopkins took her cells and them cells are still livin today, stil multiplyin, still growin and spreadin if you don't keep em forzen. Science calls her HeLa and she's all over the world in medical facilities, in all the computers and the Internet everywhere.

When I go to the doctor for my checkups I always say my mother was HeLa. They get all excited, tell me stuff like how her cells helped make my blood pressure medicines and antidepression pills and how all this important stuff in science happen cause of her. But they don't never explain more than just sayin, Yeah, your mother was on the moon, she been in nuclear bombs and made that polio vaccine. I really don't know how she did all that, but I guess I'm glad she did, cause that mean she helpin lots of people. I think she would like that.

But I always thought it was strange, if our mother cells done so much for medicine, how come her family can't afford to see no doctors? Don't make no sense. People got rich off my mother without us even knowin about them takin her cells, now we don't get a dime. I used to get so mad about that to where it made me sick and I had to take pills. But I don't got it in me no more to fight. I just want to know who my mother was."
