Somebody should ask Jo Marchant, because she did exactly that.

In Search of Now: The Science of the Present Moment by Jo Marchant
My rating: 1 of 5 stars
In a book like this, with a title like this and its subtitle, knowing that ideas of selfhood would also be involved, even though he’s a philosopher, not a scientist, I expected a hat tip to David Hume’s famous comment about trying to perceive the self:
"For my part, when I enter most intimately into what I call myself, I always stumble on some particular perception or other, of heat or cold, light or shade, love or hatred, pain or pleasure. I can never catch myself at any time without a perception, and never can observe anything but the perception."
So I looked at the index.
And Hume, this comment or any other, is not in here!
It’s not like Marchant is philosopher-ignorant. Beyond what I said in the review, her bio on Goodreads would hint at that:
Dr Jo Marchant is an award-winning science journalist based in London. She has a PhD in genetics and medical microbiology from St Bartholomew’s Hospital Medical College in London, and an MSc in Science Communication (with a dissertation in evidence-based medicine) from Imperial College London. She has worked as an editor at New Scientist and at Nature, and her articles have appeared in publications including The Guardian, Wired UK, The Observer Review, New Scientist and Nature. Her radio and TV appearances include BBC Radio 4’s Start the Week and Today programmes, CNN and National Geographic. She has lectured around the world. Her book Decoding the Heavens was shortlisted for the 2009 Royal Society Prize for Science Books.
There you are.
Besides leaning on Anil Seth for theories of mind and consciousness, she references other living philosophers like Galen Strawson, 20th-century giants like Russell, Husserl and Wittgenstein, goes all the way back to the pre-Socratics, and also references Leibniz from Hume’s own general time.
But no Hume. (And no other British Empiricist, for that matter, even though chapters a little bit over halfway through the book discuss ideas related to empiricist ideas of the mind and the universe.)
Anyway, seeing him not in here, I figured I had to check out the book to figure out how much to review-bomb it because no Hume gets you a ding for sure.
But, “ding”? Hell, no. By the time I was a fair way in, I realized this book was going to get a crushing review bombing, complete with the “mendaciousness” bookshelf tag. (I also gave it the "philosophy" tag, but, per the below, refuse to give it any tag for any natural science.)
Let’s dig in, staying with what all Marchant left out in what I am assuming is intentional philosophy bias against Hume in particular and empiricism in general.
Hume’s comments refer to ideas of a “soul” as well as self or consciousness.
From this, Hume noted elsewhere that without change, we would not have a “now.”
Hume himself writes, “that time or duration consists of different parts: for otherwise we could not conceive of a longer or shorter duration.”
Also, many sites will tell you about Hume’s influence on Einstein. They’ll also tell you, related to that, that Hume questioned Newton’s idea of absolute time.
Aeon has a long essay about this:
‘From the philosophical perspective, nothing nearly as clear seems to have been written on the topic.’ Then he went on to express his intellectual debt to ‘Hume, whose Treatise of Human Nature I had studied avidly and with admiration shortly before discovering the theory of relativity. It is very possible that without these philosophical studies I would not have arrived at the solution.’
See how mendacious it is, from that pull quote alone, for Marchant, in her many mentions of Einstein, to never mention Hume? Read the whole piece, and you'll see in blinding detail the degree of mendaciousness.
Related and coming from the latter part of the book? Her discussion of quantum theory is incomplete on the varieties of interpretations possible, including looking at it in non “romantic” terms of classical statitstical mechanics. More weirdly yet, Schrödinger is never mention in her discussion of the quantum world. At this point, I basically stopped reading and figured we were in one-star territory. My thoughts on Schrödinger, his cat, and his smoking too much Bhagavad Gita.
This all really, really came out about page 200 and shortly thereafter. Before page 100, with the Hume ding, I figured were were at best 3.5 stars rounded down, and by 150 or so, figured we were at 2 stars. Obviously, these things were the final self-burials Marchant committed.
But as noted, she was on the downslope before this.
That’s because I’m not enamored of her choices of modern philosophers of consciousness and ideas and theories of consciousness much more than I am enamored of her writing Hume out of the picture.
First, I’m not enamored of Anil Seth so leaning heavily on him can get you another ding. (Per the link? Active inference with a Bayesian background is itself not bad, but he loves to make overblown claims and is all wet on free will, including repeated strawmanning.)
And while Andy Clark, also leaned on, is somewhat better than Seth, that’s a low bar. Spinning off Clark, she proposes an enactivist version of qualia that sounds like high-octane pure empiricism, but she still can’t reference empiricism. Maybe it’s a matter of fear, of being called out for all the wrongness of empiricism.
The fact that humans’ two primary senses evolved to see electromagnetic radiation of certain wavelengths and hear certain frequencies of material vibrations show that the world of consciousness can’t be entirely “in here.” With light, in fact, all creatures with sensory organs evolved to see in roughly the same wavelengths, with some tilting more left, some more right, a few extending into either the low ultraviolet or the upper infrared, because of the wavelengths of radiation the sun puts out, followed by plant evolution, above all chlorophyll’s color. Things like this continue to put paid to the problems of empiricism or some sort of backdoor neo-empiricism that Marchant may be trying to do, even with dissing The King of Empiricists.
I mean, if you think about it, that's what some of these modern theories of consciousness are — neo-empiricism, in essence. And, that's at core of why they fall short.
I mean, human brains and sensory systems, and animal nervous systems in general, evolved for better survival odds in response to specific environments. In other words, not sensory experiences, but sensory experiences adapted to an "out there."
Although Marchant doesn’t mention directly Karl Friston and his Free Energy Principle as much, it too is considered overstated by many. One critique?
More importantly, we observe that a mathematically central step in the argument, connecting the behaviour of a system to variational inference, relies on an implicit equivalence between the dynamics of the average states of a system with the average of the dynamics of those states. This equivalence does not hold in general even for linear stochastic systems, since it requires an effective decoupling from the system's history of interactions.This applies to circa page 170. It's kind of like a high-level version of confusing "mean" and "median" as two different types of averaging.
On lesser things, I’m not sure she’s a “determinist,” but she seems to pass forward Seth’s strawmanning of free will. Beyond all of the above, per a low-star reviewer, there’s also not a “throughline” here.
Review bomb complete. And, assuming Marchant has a philosophical bias about even discussing empiricism in general and Hume in particular, I won’t read her again.
