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.

w/CS: Assembling California*, John McPhee

* Reading with CJS. Page numbers cited are from Annals of the Former World, a collection of his work of which Assembling California is only one part. The parts of the AC, as described below, are not well-separated in the text; they only appear in the table of contents.

w/RB: An Immense World: : How Animal Senses Reveal the World Around Us, Ed Yong

An Immense World: How Animal Senses Reveal the World Around Us, Ed Yong, 2022.

Overall, a good book. Yong writes well, and sometimes has very nice turns of phrase, though I’d say his gift is more for clarity and content than lyricism. The downsides of the book — small ones but nevertheless there — is that he often doesn’t go as deeply into the mechanisms and neurophysiology of sensing as I would like. It is also the case that one gets a bit of whiplash from looking first at this organism, and then at that, and then at that — but I don’t see how that could have been avoided in this sort of book.

To summarize briefly and incompletely, here are some of the points I found most interesting:

What we think of as a single sense (e.g., vision) can be quite complex. All of the following can be separate: distinguishing light from dark areas; color vision (and bi- tri- and tetra-achromatism); ability to see polarized and/or UC and/or infrared light; and more.
Also, the same sense can be configured and deployed in different ways: the shape of an organism’s visual field is tightly bound with its role in the food web; an organism may have one, two or multiple eyes, and may be able to move them independently; and so on.
Some senses seem easy to evolve, in that they have been independently evolved at many different points in time. And then lost, and then re-evolved.

Introduction

The book begins with a fanciful description of a room with different creatures in it, including a human, a robin, an elephant, a spider, and so on. It uses this to make the point that the different creatures, although all in the same room, have radically different impressions of the room and its occupants. What is evident to one is invisible to another. An organism’s very particular view of its environment – is referred to as its umveldt, coined by Jacob Uexkull in 1909.

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.
