The Forest Unseen: A Year’s Watch in Nature, David George Haskell

March/April 2026

* The Forest Unseen: A Year’s Watch in Nature, David George Haskell, 2012

In this book a biologist marks out a one-square-meter patch of forest, and visits it over fifty times during the course of a year. On each visit he observes and reflects on what he sees, starting with the concrete and then exploring a web of connections and associations that illustrate the systemic and interconnected aspects of the ecosystem. One part ecology, one part biology, one part poetry. Having read the first few entries it looks like it will be a great read. It was a finalist for the Pulitzer Prize.

Preface

Opens with a description of Tibetan monks making a mandela, and a comment that its aim is to symbolize the entire universe in this small circle of sand.

“I believe the forests ecological stories are all present in a mandala-sized area. Indeed, the truth of the forest may be more vividly and clearly revealed by contemplation of a small area than it could be by donning ten-league boots and covering a continent but uncovering little.

—The Forest Unseen, p xii

Atoms of Delight, Kenneth Steven

Atoms of Delight: Ten Pilgrimages in Nature, Kenneth Steven, 2024

March 2026

A short book of essays by a Scottish poet about, essentially, walks he has taken — essays are usually followed by a poem that relates to the walk described. I believe that the phrase “Atoms of Delight” is taken from Scottish writer Neil Gunn.

I’m enjoying the book, and the poems, but mildly rather than intensely. I stumbled across this book in a bookstore, while looking for something else. This is part of my effort to read more books that describe the landscape.

Serpentine

Recounting a walk to St Columba’s Bay that he has taken many times, both as an adult and especially as a child, and how the walk rekindles in him the feeling of being a child.

  • A memory of running ahead and waiting for his parents to catch up.
  • And, today, imagining that he can catch glimpses of his parents, from years ago, walking.
  • The bay is held in rock arms, and the ocean is fierce, not “any gentle sea lapping at the lips of the bay.
  • Somewhere out in the bay there is a reef of serpentine, and he describes the pebbles they form, “like sweets specifically designed to catch the eye of a child.
  • He describes gathering cobbles as a child — you’re either a tide dancer or a sifter. “I still come here, year on year, to be blown out of myself and into childhood.

Hold it to the light and it changes
becomes a globe of fractures;
a cavern of ledges and glinting—
not one green but many at once.

…carrying the cuts of its journey,
the brokenness letting in the light

The High Lochs

An essay remembering the highlands, where his mother’s people are from, and where his parents went for outings, his mother fly-fishing, and his father bird watching.

The fossil imprints left in the mind can only be chiseled out only as stories, because no other evidence survives.

It always seemed an impossible blue, perhaps because it was set against such dark garments of moorland.

The silence was like a thin, beautiful layer of ice, something you didn’t want to break.


At night the sky a breath of stars

Cloudberries

About a time spent in the Norwegian arctic with the Sami, shortly after Chernobyl.

The plateau wasn’t just a bare back of rock and trees: it undulated – rose and dipped and rose again. There were hollows and little dark eyes of pools that I recognised as lochans.

Conkers

Not a bad essay, but this one did not speak to me.

Hallucinations, Oliver Sacks

March 2023

This is volume #25 in the Essays Project that CT and I are doing. It is the last volume of Sacks we have not yet read; we will also read Insomniac City by Bill Hayes, his partner in his final years, just for completeness. Then it is back to essays by other authors.

Introduction

Before the 1830’s, when “hallucinations” was introduced as a medical term, hallucinations were referred to as “apparitions.” I found that interesting because in reading old literature I also assumed they were superstitiously referring to seeing ghosts. So this gives the ‘seeing of appartions’ a different flavor.

Hallucinations are defined as seeing things that are not actually there — this distinguishes them from errors of perception. And hallucination also means that what is perceived in the mind is clear and detailed — it is like seeing (or otherwise sensing) an object, except there is nothing there. This distinguishes them from mental images. Dreams could be considered a form of hallucination, but are usually treated separately.

This book does not address hallucinations that occur as a result of schizophrenia, but rather those that appear to arise, directly or indirectly, from neurological traumas.

Patterns in Nature, Philip Ball

February 2026

Patterns in Nature: Why the Natural World Looks the Way It Does, Philip Ball, 2016

About the Book

My pick for the first round of reading for the club for 2026. I’m obsessed with patterns, and this book has 250 beautiful photos. Whether it will go deep enough to teach me some new things is another question, but even if not it should be a pleasant read.

The Book

Introduction

  • In 1917 D’Arcy Wentworth Thompson published On Growth and Form. One of his aims was to counter the tendency to ascribe all patterns to evolution, to assert that they were all products of adaptation and natural selection. Instead, he argues, that often patterns simply arise from physical forces.
  • Patterns are often (always?) produced via growth.

… it does make many patterns variations on a theme, and reflects the fact that they often arise from broadly similar processes-ones in which some driving force, be it gravity or heat or evolution, prevents the system from ever settling into a steady, unchanging state; in which various influences interact with each other, sometimes reinforcing and sometimes competing; in which patterns and forms might switch abruptly to a new shape and appearance when the driving force exceeds some threshold value; in which small events can have big consequences and what goes on here can influence what transpires at a distant point there; and in which accidents may get frozen into place and determine what unfolds thereafter. 

—ibid.,

Symmetry

  • Symmetry operations: Reflection; Rotation; Translation.
  • Patterns arise through (limited) symmetry breaking. Something that is perfectly symmetric, i.e. the same under all symmetry operation, has no pattern; pattern arise from reducing symmetry. “The more symmetry that gets broken, the more subtle and elaborate the patterns.”

Fractals

  • A complex pattern may be described simply if one focuses on the process that generates it.
  • Fractal networks, having fractional dimensions, are good at spanning an integral dimensional space without filling it up.  
  • Fractal forms may be produced by growth and accumulation, or by erosion and removal.
  • Growth instabilities — self amplifying projections as in snowflake formation. 
  • In the absence of fractal structures filled spaces in which redistribution must occur must generate their own structures (e.g., convection cells or ‘pedestrian columns.’)
  • The self-similarity across scales means that a complex structure can be produced by a simple algorithm. 
  • The branching vein networks of leaves, unlike branches or roots, can intersect and join up, forming loops that provide alternative pathways if parts of the leaf are damaged. P 70. 

Spirals

  • Archimedean vs.  logarithmic 
  • Logarithmic: increase circumference as it grows; one side grows faster (to create curve). 
  • Vortices due to friction in moving fluid
  • Flow vortices vs self-organizing density waves

Flow and Chaos

  • Laminar flow
  • Shear flow
  • Kármán vortex streets
  • • • Flocking

Waves and Dunes

Bubbles and Foam

Arrays and Tiling

Leonardo Da Vinci, Walter Isaacson

October 2025

About the Book

Reading this with NS & DO, a subset of the 26 minute book group. As I begin, I find myself a little hesitant about a biography written about someone 400+ years ago, where there is presumably a scarcity of 1st hand accounts. But certainly his very detailed notebooks will help…

Later: And the notes do, indeed, help, although the undated nature of the notes, and the fact that they have been remixed over the ensuing centuries makes them less effective as a chronological record. Still, I’m learning a lot about Leonardo, his approach to life and innovation, and his accomplishments.


The Book

INTRODUCTION – I Can Also Paint

The introduction offers a general description of Leonardo as a man who blended art and science and who, in fact, probably did not distinguish. It suggests that we have much to learn from Leonardo in that “Leonardo’s genius was a human one, wrought by his own will and ambition,” in contrast to those who seem to have prodigious cognitive powers. Certainly, he left profuse documentation of his curiosity and his reliance on observation and analysis of the natural world to fuel his creativity and inventiveness. Leonardo: “He who can go to the fountain does not go to the water jar.

The rest of the introduction discusses sources — three early accounts — and offers some suppositions about Leonardo’s personality.

Gods of the Upper Air, Charles King

October 2025

About the Book

I’m reading this book chapter by chapter with CJS.The topic is the emergence of cultural anthropology via the work of Franz Boas and his students, who included Margaret Mead, Ruth Benedict, Ella Deloria, and Zora Nealel Hurdson. The work described here laid the foundation for the belief that all humans are fundamentally equal in their abilities, and that much of what had been thought to be innate was culturally constructed.

The Book

C1: Away

This chapter is really a preface. It begins with a vignette of Margaret Mead arriving in Samoa, but then segues to the general aim of the book.

A little over a century ago, any educated person knew that the world worked in certain obvious ways. Humans were individuals, but each was also representative of a specific type, itself the summation of a distinct set of racial, national, and sexual characteristics.

Each type was fated to be more or less intelligent, idle, rule-bound, or warlike. Politics properly belonged to men, while women, when they were admitted to public life, were thought to be most productive in charitable organizations, missionary work, and the instruction of children. Immigrants tended to dilute a country’s natural vigor and breed political extremism. Animals deserved kindness, and backward peoples, a few rungs above animals, were owed our help but not our respect. Criminals were born to a life beyond the law but might be reformed. Sapphists and sodomites chose their depravities but were probably irredeemable. It was an age of improvement: an era that had moved beyond justifying slavery, that had begun to shake off the strictures of class, and that might eventually do away with empires.

—ibid., p 4

The claim of the book is that the work of Boas and his students was critical to overturning these understandings. Boas and his students invented (and named) cultural anthropology and developed the theory of cultural relativity. Their work challenged heretofore accepted ideas that people fell into natural categories that differed in their abilities and predilections. It did this via a scientific examination of cultures…

The Saint of Bright Doors, Vajra Chandrasekara

The Saint of Bright Doors, Vajra Chandrasekara, 2023

This is an acclaimed science fiction book that has gathered both critical and popular praise. I read it a couple of years ago — I try to read the ‘best of the year’ books in SF – and it didn’t engage me, although I did manage to finish it. I am now reading it a second time, as part of a Science Fiction and Fantasy course I’m taking at the U, and am going to try harder to appreciate it; or at least to understand what others appreciate in it. And perhaps also reflect on aspects of it that prevent me from appreciating it.

At this point I’ve just started the re-read it. I am noticing some very nice turns of phrase. I also notice that the protagonist begins as, in a sense, an abused child who is being trained to do terrible things by a mother who sees him only as a tool. I’m not really noticing much in the way of love or affection or humor among any of the characters.

On Solitude*, Michel de Montaigne

* On Solitude, Michel de Montaigne (Penguin Books, 1991, trans. M. A. Screech)

This is the first time I have read Montaigne, a little surprising since he is the originator of the essay form. I am not sure whether I will appreciate him…

Later: Montaigne’s essays are just not engaging me. But I am struck by the way he is engages in dialog with scholars and others who have come before. I don’t really resonate with the topics and language in play, but it would be interesting for me to try to do something similar with people who have influenced me.

E1: On Solitude

This eponymous essay Is written from the vantage point of a man in the “tail-end of life,” and explores the virtues of solitude. I was struck by how much, and how widely, he quotes from the classical literature. Hoarce, Seneca, Cicero, Erasamus, Socrates. The general theme is about the advisability and wisdom of withdrawing from public life, and the vices attendant in that and in the majority of people. Instead, he advocates turning inward, and cultivating one’s own happiness and virtue in a what seems to me a stoic fashion. This essay did not, in general speak to me, though there were a couple of quotes I liked. 

“We have lived quite enough for others; let us live at least this tail-end of life for ourselves. Let us bring our thoughts and reflections back to ourselves and to our own well-being”

ibid. On Solitude, p. 9

“If a hangover came before we got drunk we would see that we never drank to excess: but pleasure, to deceive us, walks in front and hides her train.

EP#20: The Man Who Mistook his Wife for a Hat, Oliver Sacks

* The Man Who Mistook his Wife for a Hat, Oliver Sacks. 1984

The 20th volume in the Essays Project (co-reading with CT) gets us back to essays. Here we are continuing our side quest to read all of OS’s work. This is Sack’s fourth book, and its excellence is consistent with my belief that Sack’s somehow found his muse — at least for writing for general audiences — while writing A Leg to Stand On, his previous book. Hat, so far, seems to be about various forms of agnosia — the loss of knowledge or awareness of things. So far this includes face and object recognition, awareness of limbs (or the entire body), and portions of the visual field. Looking ahead, I now see that only the first section is on “Losses,” so there will clearly be a much wider variety of ‘neurographies.’

The Book

Preface to the Original Edition (1985)

There is also a 2013 Preface, but I find little of note, though if you are reading the book it is worth a quick perusal.

Sacks begins the 1985 Preface by reflecting on his epigraphs, which has to do with his practicing medicine as a physician also involving getting a view of the larger context of his patients’ troubles — he sees himself as as much as naturalist as a physician. He also says, interestingly, that: “animals get diseases; only man falls radically into illness.” In my view, this reflects his view that some (all?, almost all?) diseases have an ontological component. I love the comment in one of his letters: “What is so instructive about disease, like disaster, is that it shakes the foundations of everything.” He also discusses the value of broad accounts, even stories, and laments the modern tendency to eliminate or minimize the subject of ‘case histories:’ “To restore the human subject at its center — the suffering, afflicted, fighting human subject — we must deepen a case history to a narrative or tale….” (p. xviii) He also brings in myths and fables with their hero’s and archetypes — “travelers to unimaginable lands, lands of which we should otherwise have no idea or conception.

Migraine*, Oliver Sacks

*Migraine (Revised and expanded), Oliver Sacks, 1992

This is the 18th volume in the “Essays Project.” While the Essays Project has focused mainly on essays, we became intrigued with Oliver Sacks and are taking something of a detour to read his complete work, essays or not.

[[More to come…]]

Front Matter

There are prefaces to the original edition, and, to this, the 1992 edition. There is also a forward by William Gooddy, a migraine specialist whom Sacks praises in his prefaces. There is also a historical introduction, which summarizes over 2,000 years of medical writing on migraine; I will pass on summarizing this.

The following, from the ’92 Preface, is Sacks’ comment on the aims of the book; I think his thoughts on why humans may need to be ill, for a brief time, will be very interesting.

Migraine, of course, is not just a description, but a meditation on the nature of health and illness, and how, occasionally, human beings may need, for a brief time, to be ill; a meditation on the unity of mind and body, on migraine as an exemplar of our psychophysical transparency; and a meditation, finally, on migraine as a biological reaction, analogous to that which many animals show.

A Room of One’s Own, Virginia Woolf

Reading on my own, circa Fall 2024.

This book or extended essay is based on a lecture on Women and Literature that Woolf gave, or at least that is the framing of it in the book. She approaches the topic by explaining how she came to develop her thoughts about it:

“At any rate, when a subject is highly controversial–and any question about sex is that–one cannot hope to tell the truth. One can only show how one came to hold whatever opinion one does hold. One can only give one’s audience the chance of drawing their own conclusions as they observe the limitations, the prejudices, the idiosyncrasies of the speaker. Fiction here is likely to contain more truth than fact.”

She begins with an account of going to Oxbridge, and walking about the colleges. She notes that, being a woman, she is barred from walking on the grass, and is not welcome in the library. She has lovely descriptions of the landscape and colleges:

To the right and left, bushes of some sort, golden and crimson, glowed with the colour, even it seemed burnt with the heat, of fire. On the further bank the willows wept in perpetual lamentation, their hair about their shoulders. The river reflected whatever it chose of sky and bridge and burning tree, and when the undergraduate had oared his boat through the reflections they closed again, completely, as if he had never been.

And as we accompany her, she recounts her thought process. I love her metaphor (more extensive than the excerpt I quote) of thinking as fishing…

Thought — to call it by a prouder name than it deserved — had let its line down into the stream. It swayed, minute after minute, hither and thither among the reflections and the weeds, letting the water lift it and sink it, until–you know the little tug–the sudden conglomeration of an idea at the end of one’s line: and then the cautious hauling of it in, and the careful laying of it out?


Pausing in my account here, but passages that I like for various reasons follow:

“Lamb is one of the most congenial; one to whom one would have liked to say, ‘Tell me then how you wrote your essays?’ For his essays are superior even to Max Beerbohm’s, I thought, with all their perfection, because of that wild flash of imagination, that lightning crack of genius in the middle of them which leaves them flawed and imperfect, but starred with poetry.


“Many were in cap and gown; some had tufts of fur on their shoulders; others were wheeled in bath-chairs; others, old though not past middle age, seemed creased and crushed into shapes so singular that one was reminded of those giant crabs and crayfish who heave with difficulty across the sand of an aquarium. 


Fiction must stick to facts, and the truer the facts, the better the fiction — so we are told. “


“It was the time between the lights when colours undergo their intensification and purples and golds burn in window-panes like the beat of an excitable heart; when for some reason the beauty of the world revealed and yet soon to perish (here I pushed into the garden, for, unwisely, the door was left open and no beadles seemed about), the beauty of the world which is so soon to perish, has two edges, one of laughter, one of anguish, cutting the heart asunder. The gardens of Fernham lay before me.”


“I thought at last that it was time to roll up the crumpled skin of the day, with its arguments and its impressions and its anger and its laughter, and cast it into the hedge. A thousand stars were flashing across the blue wastes of the sky. One seemed alone with an inscrutable society.”




TBD –The first chapter is brilliant, and I have high hopes for the rest of the book, but have gotten distracted! But I shall return.

LS: Land Above the Trees: A Guide to American Alpine Tundra, Ann Zwinger & Beatrice E. Willard

February 2024…

This book was recommended in Kim Stanley Robinson’s The High Sierra: A Love Story, as a good guide to the ecology and botany of the Sierra Nevada (and the upper portions of other North American ranges). And, indeed, it is beautifully written with a narrative style in which the reader moves through landscapes with the authors, looking at this and that, in contrast to what I had expected would be more of a catalog or encyclopedic approach. The book is divided into two principle parts: part 1 examines elements of ‘above the trees’ ecosystems, like fellfields or krumholtz; part 2 looks at particular North American tundra ecosystems, with one chapter being on the Sierra Nevada.
