A Leg to Stand On, Oliver Sacks

June 2024

The 19th volume we’ve read in the increasingly poorly named Essay Project, this being (another) book that does not contain essays. But we’ve become fascinated by O.S. from reading his two autobiographies and the edited collection of his letters, and just can’t stop.

This is the third book that Sacks published (1984), following Migraine and Awakenings. So far (just at chapter 3 when writing this), it seems to be the book where he found his narrative voice, or at least the voice that proved so engaging to non-medical readers. It strikes me as a breakthrough in his writing style. It is a gripping narrative, with lucid and beautiful writing. Gone are the clinical passages and case histories that were interspersed throughout his first two books. It will be interesting to see if his subsequent  ‘neurographies’ continue in this more narrative and engaging voice. 

This book begins with an accident in 1974 in which O.S. nearly died, severely injured his leg and, during his recovery, experienced very odd neurological ‘side effects.’ The book discusses both the neurological issues, but also leads him to reflect on the state of institutional medical care, and — from his new vantage point as a patient — the relationship between physician and patient.

C1: The Mountain

Sacks hikes up a mountain in a remote area of Norway; he believes he is the only person within 10 miles. Part way up he encounters a gated fence and a sign that says “Beware of the Bull.” He ignores it and proceeds. 

A couple miles farther up the mountain he rounds a rock and encounters the bull:

It had a huge horned head, a stupendous white body and an enormous mild milk-white face. It sat unmoved by my appearance, exceedingly calm, except that it turned its vast white face up towards me. And in that moment, in my terror, it changed, before my eyes, becoming transformed from magnificent to utterly monstrous. The huge white face seemed to swell and swell, and the great bulbous eyes became radiant with malignance. The face grew huger and huger all the time, until I thought it would blot out the universe. The bull became hideous-hideous beyond belief, hideous in strength, malevolence and cunning. It seemed now to be stamped with the infernal in every feature. It became, first a monster, and now the Devil.

Oliver Sacks, A Leg to Stand On, p. 5-6

He panics “and runs heedlessly down the mountain “and I ran for dear life-ran madly, blindly, down the steep, muddy, slippery path, lost here and there in patches of mist. Blind, mad panic! —there is nothing worse in the world-nothing worse, and nothing more dangerous.” He has no memory of the accident, but regains consciousness at the bottom of a cliff. His left leg is badly injured. He assesses the situation and realizes that if he is not able to get back down the mountain he will die of exposure when night comes. 

He manages to splinter his leg with an umbrella and begins to drag himself down the mountain. He tries to call for help, but falls into a panic again, believing he may have attracted the bull and hides. Nothing happens. He recovers and continues making his way down. Evening comes, and he can see the villiage he left from far below, and realizes he will not make it. Then, ten minutes before total darkness arrives, he hears a yodel and is rescued by a shepherd and his son. They care for him, summon help from the village, and he is rescued. 

ADD NOTE ON HIS PAYCHOLOGACAL STATE DURING THUS TIME. 

C2: Becoming a Patient

Sacks is taken to a very small hospital. It is decided that he should return to London for surgery on his leg. But while he is in the small hospital he has an amazing experience.

I immediately fell asleep again, and slept soundly and well until a most amazing apparition entered the room, so that I rubbed my eyes thinking I was still dreaming. A young man-dressed, preposterously, in a white coat, for some reason came in dancing, very lightly and nimbly, and then pranced round the room and stopped before me, flexing and extending each leg to its maximum like a ballet dancer. Suddenly, startlingly, he leapt on top of my bedside table, and gave me a teasing elfin smile. Then he jumped down again, took my hands and wordlessly pressed them against the front of his thighs. There, on either side, I felt a neat scar.

“Feel, yes?” he asked. “Me too. Both sides. Skiing … See!” And he made another Nijinski-like leap.

Of all the doctors I had ever seen, or was later to see, the image of this young Norwegian surgeon remains most vividly and affectionately in my mind, because in his own person he stood for health, valor, humor-and a most wonderful, active empathy for patients. He didn’t talk like a textbook. He scarcely talked at all he acted. He leapt and danced and showed me his wounds, showing me at the same time his perfect recovery. His visit made me feel immeasurably better.

–ibid., 27

Sacks is transported to London and has a disillusioning experience with the dehumanizing bureaucracy if the hospital.  Before and after the surgery  he  has a disappointing experience with the surgeon, though the nurse is kind. He discovers that his injured leg is unnaturally flaccid and that he can neither move nor feel it. The PT person is horrified, as is he, but the surgeon ignores his concerns. As time progresses he loses the sense that the leg even belongs to him; he cannot imagine it or imagine how to tense its muscles or otherwise control it.  He finds this experience bizarre and terrifying. Thus ends chapter 2.

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.

–Oliver Sacks, Migraine, xv

I. The Experience of Migraine

C1. The Common Migraine

As I read through this chapter, the vast range of symptoms and manifestations attributed to Migraine would seem to defy any sort of classification. However, Sacks grapples with this by describing constellations of symptoms, and also sequences of symptoms/constellations, and leaves me with the sense that Migraine really is a distinct and identifiable entity.

One thing which I think, perhaps, he does not emphasize enough is that migraine recurs over the course of months and years, and I think that it is this pattern of recurrence (even though the symptoms may change completely) that I find most convincing.

Sacks’ high level description is that there is a prodomal phase (when the first hints of what is coming occur), the attack proper, resolution, and finally rebound. I’m particularly struck by the fact that both prodomal and rebound phases may often (but not invariably) include feelings of great well-being.

II. The Occurrence of Migraine

This section examines when migraines occur, and divides them into periodic (occurring a particular times and with particular rhythms of occurrence), circumstantial (appearing in response to particular circumstances), and situational (as a reaction to intolerable situations such as stress).

III. The Basis of Migraine

We skimmed this section, except for focusing on the psychological causes of migraine.

IV: Therapeutic Approaches to Migraine

We only skimmed this section. As the title suggests, it has to do with approaches to avoiding, ameliorating or otherwise treating migraines.

V: Migraine as a Universal

This section is really just one chapter which is on Migraine Aura and Hallucinatory Constants. It discusses, and tries to systematize the types of hallucinations seen during the migraine aura phase. There are three types: phosphenes (stars and scintillating points of light); spectra: the classical expanding scotoma with its ‘fortification edges’; dynamic geometric patterns (grids, mosaics, spirals, etc.)

The interesting thing about these hallucinatory phenomena is the possibility that they are a direct reflection of activity and function of cortical cells. For example, the ‘fortifications’ around the edge of a scotoma may (perhaps) be produced by groups of edge/orientation detecting cells. Similarly, Alan Turing described how waves of chemical reactions can give rise to regular geometric patterns in “The Chemical Basis of Morphogenesis.”

Another thing this brought to mind was John Conway’s Game of Life, in which 2D cellular automata with simple rules can produced spreading and repeating patterns of activity. See the wikipedia article. One wonders if the cortex, when undergoing a migraine, can generate such spreading and repeating patterns.

EP #16: Letters, Oliver Sacks

December 2024 – April 2025

This is book # 16 in the no-longer-very-aptly named Essays Project. Though perhaps, having detoured into the wilds of Shakespeare, a tour of the letters of Sacks, who is a formidable essayist, is steering us back towards the main track. Of course, letters are not essays, but their relative brevity and personal cast, as well as the wide-ranging nature of Sack’s epistles, give them a familial resemblance. 

The book is edited by Kate Edgar, Sacks’ assistant and editor of several decades; she also contributes a brief preface which offers her perspective on Sacks’ compulsive writing process. Alas for her brevity; I believe she could offer a lot of insight on Sacks. But perhaps his letters will serve. Onward!

Preface and Editor’s Introduction

Sacks loved correspondence. He felt one ought to reply to letters, immediately if possible. He corresponded with, literally, thousands of people, from school children to Nobel laureates.  Sacks took pains to preserve his letters with carbon sets, drafts, or later, photocopies, though by no means does all his correspondence survive. But that part which does runs to about 200,000 pages, or about 70 bankers’ boxes.

EP #`13: Awakenings, Oliver Sacks

January 2024

Entry 13 in the Essays Project with CT; this is the seventh book we’ve read by Oliver Sacks. This is the book that, with the help of a documentary and then movie, transformed him into something of a celebrity. It is an account of the experience of ‘awakening’ patients with Parkinson’s induced by Encephalitis Lethargia by administering L-Dopa, their experiences of returning to a sort of normal life, and then their declines due to the follow-on negative effects of L-Dopa.

EP#12: The Mind’s Eye, Oliver Sacks

Entry 12 in the Essays Project with CT; and this is the sixth book we’ve read by Oliver Sacks. Here we take up the neurological case account essays for which he is best known, after reading his two autobiographies, and other writings ranging from general essays to an account of his travels in Oaxaca. This book, published in 2010, explores cases in which people have lost visual abilities that we all take for granted – not so much blindness (although maybe there will be some essays on that), but rather the consequences of some of the many ways in which the complex and intertwined elements of the visual processing system may be disrupted.

EP #11: Uncle Tungsten: Memories of a Chemical Boyhood*, Oliver Sacks, 2001

Entry 11 in the Essays Project with CT; the ‘summer of Sacks’ has turned into the fall of Sacks. It is interesting to be getting such a comprehensive view of a single person’s life and writing. Uncle Tungsten was apparently written in response to the spontaneous surfacing of childhood memories as Sacks approached his 60th year. We’ve read some other essays from that time, mostly from Everything in its Place (essays on South Kensington and Humphry Davies), and found those very good though we hope considerable new ground will be covered. [Later: New ground is being covered — there is not a lot of repetition…]

EP #10*: The River of Consciousness, Oliver Sacks

*The River of Consciousness, Oliver Sacks, 2015.

This is part of the course of essay reading I am doing with CT; in particular, this is part of what we have dubbed ‘The Summer of Sacks.’ According to the introduction, this book was posthumously assembled at Sack’s direction a couple of weeks before his death. One of the catalysts was a televised panel with other notable scientists and scholars — Gould, Dyson, Dennet, etc. — that was later captured in a book called “A Glorious Accident.” This book contains a wide range of essays on scientific topics, with, I suspect, particular attention to history.

EP #9*: On the Move: A Life, Oliver Sacks

*On the Move, Oliver Sacks, 2015.

These are my notes on On the Move, Oliver Sacks autobiography (billed as volume 2, but the publisher, volume 1 being Uncle Tungsten: Memories of a Chemical Boyhood, written a couple of decades earlier). This is part of the course of essay reading I am doing with CT; in particular, this is part of what we have dubbed ‘The Summer of Sacks.’ These are not, of course, essays, but we have become interested in Sacks, and it is interesting to see the essays against a fuller narrative of his life.

EP #8*: Oaxaca Journal, Oliver Sacks

Oaxaca Journal, Oliver Sacks, 2019.

These are my notes on Oaxaca Journal, by Oliver Sacks, 2019. This is part 8 of the course of essay reading I am doing with CT; in particular, this is part of what we have dubbed ‘The Summer of Sacks.’ Strictly speaking, these are not essays but rather chapters — or daily entries – from a journal he kept of a trip to Oaxaca, Mexico, with the American Fern Society.

Introduction

Sacks opens by writing of his love of the Natural History journals of the nineteenth century, and their blend of the personal and professional. He notes that most of the naturalists were essentially amateurs, self-taught, and feeling their way before or as biology and botany were crystalizing into sciences. He adds:

This sweet, unspoiled, preprofessional atmosphere, ruled by a sense of adventure and wonder rather than by egotism and a lust for priority and fame, still survives here and there, it seems to me, in certain natural history societies, and amateur societies of astronomers and archaeologists, whose quiet yet essential existences are virtually unknown to the public. It was the sense of such an atmosphere that drew me to the American Fern Society in the first place, that incited me to go with them on their fern-tour to Oaxaca early in 2000.
