Who's there?

[With the claim that the self is like a waterfall, Julian] Baggini is trying to save the self from neuroscience, which is admirable considering that neuroscience continues to show how convoluted our brains are. I am not sure if he is successful – argument by metaphor can only go so far, empirical data wins at the end of the day.

-- so writes Sam McNerney. But Baggini's point may be sounder than McNerney allows. Nor is it particularly new. In A New Biology for a New Century (2004), Carl Woese writes:

Imagine a child playing in a woodland stream, poking a stick into an eddy in the flowing current, thereby disrupting it. But the eddy quickly reforms. The child disperses it again. Again it reforms, and the fascinating game goes on. There you have it! Organisms are resilient patterns in a turbulent flow.

It may be objected that a conscious self is an altogether different kind of thing from a non-conscious biological organism, but why?  Doesn't it make more sense to suggest that consciousness is, among other things, something like a light bulb on a dimmer switch: continuous from off through dim to bright?

John Keats wrote that he lived a life of allegory. However you take it, we are something like what Robert Sapolsky almost calls obligate metaphorists.

Setting aside any judgement on Rupert Sheldrake,  Mary Midgley is right when she writes: 'We need a new mind-body paradigm, a map that acknowledges the many kinds of things there are in the world and the continuity of evolution.'

The eyes of Anomalocaris

...this magnificent animal, probably the first in the line of apex predators of these shallow seas, had a compound eye that, in many ways, resembled the eye of today’s dragonfly. Anomalocaris had perhaps as many as 16,000 hexagonal facets (individual units of the eye called ommatidia) in each eye and probably good vision.

On being and not being astonished

...Studying patients has taught us where memories might be stored, but not what physically constitutes a memory. The answer lies in the multitude of tiny modifiable connections between neuronal cells, the information-processing units of the brain. These cells, with their wispy tree-like protrusions, hang like stars in miniature galaxies and pulse with electrical charge. Thus, your memories are patterns inscribed in the connections between the millions of neurons in your brain. Each memory has its unique pattern of activity, logged in the vast cellular network every time a memory is formed...

-- from What are memories made of? by Hugo Spiers

...Perhaps it is not surprising that we do not live more surprised. After all, we are used to unlikelihood. Being born into it, raised in it, we become acclimated to the altitude, like natives in the Andes. Moreover, we all know that the astonishment is transient, and sooner or later our particles will go back to being random...

'We have become, in a painful, unwished-for way, nature itself.'

The text of my book went to the copy editors a little while ago so it is basically done and dusted (bibliography, permissions for quotation and images, minor corrections notwithstanding). It will be published in October.

Looking over the final chapter yet one more time (and promped in part by an interview with Emma Marris at Chinadialogue), I turned thence to 'Natural Man' by Lewis Thomas, first published in The Lives of a Cell in 1974.   I think this essay, from which I quote in my final chapter (and which can be found online here) may be one of the wisest of recent decades.

'Strange places fish live'

In bottoms, in trees, in hot water, inside females, in Hadal depths, in mouths, in deep sea vents, in shells, in the dark, in anemones, underground and in places that are not known more...

Soap, fertilizer, glycerin for blowing up soldiers, margarine

A. Remington Kellogg...was among the first to commission “vivisections” on porpoises even though, in his own words, “a live porpoise can be handled about as readily as a satchel of dynamite.” This did not deter the intrepid scientists who “fell to the unlovely task of restraining the furiously squealing animal in order first to expose the skull and then to saw into it to expose the brain.” When these operations were performed, Kellogg was witness to “a strangely large brain, one with elaborate patterns of convolution such as were generally thought to be more or less unique to human beings.”

Books

Each species is like a book, the product of literally billions of years of editing and re-editing through the process of evolution, and each species has its own unique story to tell. These stories are all nonfiction, and more important, stories of survival, of navigating billions of years of persistence. These stories include the cures to many (if not all) human diseases. They include instructions for converting sunlight into stored chemical energy with near-perfect efficiency. But the most important stories are the ones we have not yet imagined.

Eaten

The consumption of animals such as whales, dolphins and manatees is on the rise in poor nations. Declines in coastal fish catches have led people to look for other sources of meat...

Cetaceans are making their way to dinner plates as other protein sources are dwindling in coastal areas of west Africa, Peru, Brazil, Colombia, Trinidad and Tobago, Madagascar, Sri Lanka, India, the Philippines and Burma. From 1970 to 2009, at least 92 species of cetaceans were eaten by humans.

You, robot

2012 is the centenary of the birth of Alan Turing, the second world war code-breaker who dreamed up the test in 1950 while pondering the notion of a thinking machine, so expect a flurry of competitions in his honour. Bear in mind, though, that the Turing test is a poor gauge for today's AIs. For one thing, the test's demand that a program capture the nuances of human speech makes it too hard. At the same time, it is too narrow: with bots influencing the stock market, landing planes and poised to start driving cars, why focus only on linguistic smarts? One alternative is a suite of mini Turing tests each designed to evaluate machine intelligence in a specific arena. For example, a newly created visual Turing test assesses a bot's ability to understand the spatial relationships between objects in an image against that of a human. Others want to stop using humans as the benchmark. Using a universal, mathematical definition of intelligence, it could soon be possible to score people and computers on a scale untainted by human bias. Such universal tests should even be able to spot a bot that is far smarter than a human.

'the infinite succession of soft and radiant forms'

If anyone goes down to those shores now, if man or boy seeks to follow in our traces, let him realize at once, before he takes the trouble to roll up his sleeves, that his zeal will end in labour lost. There is nothing, now, where in our days there was so much. Then the rocks between tide and tide were submarine gardens of a beauty that seemed often to be fabulous, and was positively delusive, since, if we delicately lifted the weed curtains of a windless pool, though we might for a moment see its sides and floor paven with living blossoms, ivory-white, rosy-red, grange and amethyst, yet all that panoply would melt away, furled into the hollow rock, if we so much as dropped a pebble in to disturb the magic dream.

-- so wrote Edmund Gosse, recalling his boyhood seashore explorations on the Devon coast with his father in the 1850s.

News from Scotland, including (supposedly) the first sighting in British waters of the ancient amphioxus, or lancelet, indicates that at least a few inshore locations in the north of this island have survived the ravages of more than a century of intense fishing and other depredations. Could this be a token of more to come, and of a measure of recovery?

Nearly all the women were wearing head scarves, even burkas. I saw one woman so pious that her burka didn't even have an opening for her eyes. She was leaving a cell-phone store, accompanied by a teen-age boy wearing a T-shirt that said "RELAX, MAN," over a picture of an ice-cream cone playing en electric guitar. You wouldn't think an ice cream could play a electric guitar, or would want to. I was reminded of Schmidt's hypothesis [with respect to Göbekli Tepe] that hybrid creatures, unknown to neolithic man, are particular to highly developed cultures - cultures which have achieved distance from and fear of nature. If archeologists of the future found this T-shirt, they would know that ours had been a civilization of great refinement.

-- from The Sanctuary by Elif Batuman, who says that she likes to think that 'when it comes to identifying a headless man with an erection, I'm as sharp-eyed as the next person.'

Among the things about Göbekli Tepe that I did not know, and learned from Batuman's piece, is archaeologists speculate that the weak foundations of the stones may have had some acoustic purpose: perhaps the pillars were meant to hum in the wind. (See this)

'Bears, dolphins and the animal stories we tell'

We don’t have to understand animals in order to care about them or in order to feel obliged to treat them in a certain fashion.

Mind in life

Am also late off the block on this from Alva Noë:

Plants are living beings, even the simplest ones, even the cell, are already engaged in an autonomous struggle to maintain themselves and survive. Living beings, even the simplest ones, already have something like rudimentary minds — motivated sensitivities and useful interests — and so they are way beyond [the IBM robot] Watson.

'Turtles might deposit eggs in the sand of the beach where now the walrus sleeps'

Then might those genera of animals return, of which the memorials are preserved in the ancient rocks of our continents. The huge iguanodon might reappear in the woods, and the icthyosaur in the sea, while the pterodactyl might flit again through the umbrageous groves of tree ferns. Coral reefs might be prolonged to the arctic circle, where the whale and narwal now abound. Turtles might deposit eggs in the sand of the sea beach, where now the walrus sleeps, and where the seal is drifted on the ice-floe.

Scientific killing

The [method] that is now mostly used is a technique in the Antarctic that uses sonar. Not, however, to look at the whale underneath the water. They use it as a means of scaring [it], because sonar is very loud. They did experiments and chose a frequency which kept whales so panicked, that they were at the surface for breaths more frequently than at other frequencies. So, they drive the whale along at the surface and then they fire into it.

-- Roger Payne in an interview with Yale 360. Payne says that following the 1986 moratorium the total number of whales killed world wide was 185 a year. It has climbed steadily even since, reaching 1,004 by 2009

'That beauty exists at all in a damaged world is to be celebrated'

"Linguistic disobedience" might be achieved in many ways: by speaking out of turn, by disrupting syntax and "meaning", and by offering comparisons between disparate things. It might be a case of the poem acting as "witness", a recording of what's normally "unseen", ignored or denied. It can be subtle -- using allusion and slight shifts from convention -- and it can be volatile -- from agitprop to rants.

An activist ecological poem might offer a glimpse of deep natural beauty that is nonetheless necessarily "disrupted" by the highly disturbing reality of species loss, deforestation or, say, the ecological implications of buying the latest flat-screen television technology. That beauty exists at all in a damaged world is to be celebrated, but our appreciation of it comes so often at a cost that we don't always register. We must be conscious of its vulnerability.
