Metaphor & mind

In a recent New Yorker article about the trial of Charleston church shooter Dylann Roof, Jelani Cobb reports that during the lead prosecutor’s presentation

Roof’s mother sank down on the bench as he delivered his opening statement, which contained details of the crime that had previously been withheld from the press. At a certain point, she slumped over. It seemed for a moment that she had fainted, but she was taken to a hospital, and it was later learned that she had suffered a heart attack. She survived, but did not return for the remainder of the trial.

In her situation, I might have had the same response. How metaphorical: the heart revolts from within–an embodied reaction. When I read about this incident, I thought of cognitive scientist/philosophers George Lakoff and Mark Johnson, who have been pioneering the concept that the mind and body evolved together and cannot be separated through the literal, analytical, categorical approaches of classic Western thought.

Languages the world over use body-based metaphors and gestures that reinforce how our  minds are integrated with and connected to our human bodies–we intuit from the gut; a situation makes our skin crawl; we place hands over hearts to demonstrate love, loyalty, compassion. Medical science confirms what people have long understood, in a “folk physiology” way, for years: emotional and intellectual stress has physical expressions and repercussions.

Lakoff and Johnson have been investigating such universal human phenomena since the 1970s. Their work has implications for a wide range of endeavors from artificial intelligence to brain trauma. In 1999, when Philosophy in the Flesh was published, they said Western philosophy needs to retool its thinking from the ground up, the ground being the body itself.

Reason, they assert, is as embodied as emotion; and their argument that intellectual functioning arises metaphorically through the physiological experiences of the (human) body is persuasive and extensively documented through research, particularly neurological research. Exactly where what we term “consciousness” arises may never be determined, but phenomenology, Taoism, and empirical science converge with what we are learning about synapses, cells, hormones, and the neural network to suggest there may be an answer as to how consciousness emerges; and that answer is likely to be biological.

The brain, the heart, the entire bodily system under emotional, mental, psychological duress, the conflicting moods of love, grief, anger, fear, and a chasm of misunderstanding; the terrible awe of disbelief–an embodied self might well collapse, physically, literally, under the metaphorical strain.

 

 

Knowing the mind

I am reading an unusual pairing of books…Joseph Fins’ Rights Come to Mind and George Lakoff & Mark Johnson’s Philosophy in the Flesh. One is about traumatic brain (and to some extent, spinal) injury and the differences between minimally conscious states and persistent vegetative states, and what we know–or mostly, don’t know–about the brain and its ability to recover or reorganize (see also Will Storr’s article from 2015 about some recent medical discoveries in neurology).

The other book is an inquiry into how Western philosophy may be seriously challenged by scientific, empirical findings about the embodiment of the conscious self. Then, after suggesting that neural pathways help us to create abstract reason–largely through metaphor–he asks whether we can adequately understand the world through science alone!

Fins’ book is not elegantly written, from a literary standpoint; but he raises hugely important questions about consciousness, healthcare decision-making, medical institutions’ and physicians’ difficulties dealing with how to measure consciousness and brain activity–to determine who may be “locked-in” or who is minimally conscious, or which patients will never recover any conscious neural activity again. Fins details the agony of family members making impossible decisions in a medical system that often views brain-trauma victims as medical failures when the patient does not recover quickly enough; he asks us: by what measure is quickly-enough? (Usually, as determined by a health care insurer…alas, my family has been snarling with too-general insurance categories lately, so I am sympathetic to Fins’ perspective).

These are tough areas to investigate, and his argument is that physicians and researchers have not spent enough time investigating them. He also asserts that this would not be a waste of money on irreparably-injured patients, because we can learn much about the brain’s capacity to heal through observation, therapy, and scans of such people. He takes pains to be certain his readers recognize how much remains unknown about the brain and human consciousness. (Here, I refer my own readers to Douglas Hofstadter’s book I Am a Strange Loop).

In the Storr article cited above, Greg Downey, co-author of the blog Neuroanthropology, cautions: “People are so excited about neuroplasticity they talk themselves into believing anything.” And it is true, there’s a chance of false hope and huge disappointment here. But the brain does exhibit an astonishing ability to rewire itself–in the body.

Which brings me to Lakoff & Johnson’s text. Lakoff calls himself a cognitive scientist, not a philosopher. He says, “In 1978, I discovered that metaphor was not a minor kind of trope used in poetry, but rather a fundamental mechanism of mind.” He and his colleagues have gone on to provide a body of evidence to support this claim that they’ve been working on since the late 90s.

As a poet interested in neurology and in philosophy, these claims interest me. As a person whose elderly best-beloveds are now beginning to show evidence of significant cognitive lacunae…or “decline”…I am interested in losses of neural plasticity, or perhaps a misfiring in the processes of rewiring. The evidence of such losses are, indeed, embodied. Gaps in the ability to recognize metaphor or analogy appear. On a recent visit, the nonagenarian said, “I can no longer seem to say any of the things I want to say, that I hear in my head, but can’t…can’t seem to…make. Make into the world. Do you know what I’m saying?”

A word is dead
When it is said,
Some say.
I say it just
Begins to live
That day.

Struggling with words

Some of the students I tutor in writing are English learners–advanced English learners, but still on the learning curve. They began speaking and writing English at age 10 or 14 or 16, or perhaps earlier, but in a family whose English defaulted to a “home” language. They often have vocabularies that far exceed my US-born students in scope, but they lack awareness of idiomatic preposition use or skills in standard English syntax.

My background is not in “ESL,” “ELL,” or the instruction of multi-lingual students. I have precious little training in that area, and no experience in translation. I do not even have fluency in any language other than my own; as a result, I have great respect for my students, who often are conversant in two, three, sometimes four languages or dialects. In truth, their language skills far outstrip my own. Yet they arrive at my door seeking help in writing, trying to understand how to write clear, concise sentences in a language they find mysterious and arbitrary in its grammar, its use of punctuation, and its rules about documentation, capitalization, and articles.bkmk-violet

The majority of them are from immigrant families, and they are among my hardest-working students. They take nothing for granted. Their frustration at not getting their ideas across on paper drives them to read more, to look words up in the dictionary (something few of my English-speaking students ever bother to do), to visit the writing tutors, to ask interesting questions about why the noun-count adjective comes before the color or quality adjective and when and why to use a rather than the as a preceding article.

They are excellent critical thinkers, probably because they have to solve problems continually: translating in their heads, figuring out whether a translator app will help them or not, deciphering figures of speech and cultural allusions, and navigating how to get around in the world outside their home base and home language.

Some of them have had to learn to handle stereotyping, ostracizing, bullying, and worse.

I admire their resilience and their youthful enthusiasm, and I recognize their dismay when nothing they try seems to work. The only aspect of their lives I am really privileged to help them with is their writing in English as they struggle with words. The rest they do on their own.

So here’s a story.

A student who has lived in the US for four years and who speaks one of the Asian languages regularly meets with me to go over her mathematics essays (these are basically chapter summaries with reflections). Her papers are usually well-structured and demonstrate considerable understanding of some complicated readings, but she does wrestle with article use and past-participle verb use in the various conditional tenses. Every once in awhile, though, she composes a sentence that completely throws me.

In a recent paper, her concluding paragraph contained the phrase “is not anhydrous warehouse confusion.”

[WTF?!] I had to wrap my brain around the possibilities of that one…so she pulled out her cell phone translator and we played around with it a bit: “without water,” a scientific term; I knew that had to mean “dry,” but why hadn’t she come up with the word “dry”? She knows that word. And “warehouse”? “Like store,” she said. [Storage? Dry storage? Confusion?]

After some laughter and some consternation, we realized that she was using a metaphor that means, essentially, dry facts. She wanted to write that mathematics is not just a set of confusing dry facts, as many people think it is. And we discovered that the metaphor in her language was not that different from the metaphor in English. But Google Translate doesn’t realize that!

I got home and said to myself: somehow I have to write a poem that contains the phrase anhydrous warehouse😀

Translation software, AutoCorrect and GrammarCheck are algorithms. They may be full of information, but they are not smart and they are not human beings. The genuine problem-solver, the best puzzler-outer, is the messy ol’ brain itself: human consciousness.brain

 

 

 

 

 

Garden breach

Summer solstice. The robins are on their second brood; mulberries are ripening, and the bluebirds have arrived for the feast.

Fifteen years ago, we set up my garden to be as impregnable as possible from incursions by deer, groundhogs, and rabbits. We accomplished this by digging a narrow trench on the perimeter, lining the trench with wire mesh fabric, and filling the trench with gravel–after setting the steel posts and putting the steel wire fencing in place. The strategy even deterred weeds for about three years.

But rain and snow and air and therefore rust, along with ground heave and the occasional bump by lawnmowers, have had their way. While deer still ignore the plot, this year, bunnies have breached the fence. It’s time to find a new way to keep them from the edges.

I have previously written about how fringes and perimeters can be boundaries or places of activity and fluidity, so it seems I am a hypocrite for keeping my rabbits at bay. Maybe I ought to find a balance? Living with their denuding of my carrot tops?

–No, they’ve plenty to eat in my lawn and in the meadow. The balance goes both ways.

Their persistence interests me. Their movements are both awkward and graceful. Their ears are translucent in the early morning sunshine. I don’t mind having them around as long as they stay out of my vegetable patch, and they feed the owls and hawks, whom I also enjoy.

All along the edges…

Curious information note of the day:

According to neuroscientific studies, less than 0.1% of the information carried in the optic nerve at any given moment passes through the visual attentional gateway (“bottleneck”) after the attentional gateway recognizes a cue; the cue evidently serves as a gating mechanism to regulate the flow of image data.*

What this implies (I think) is that the bunny I manage to spot under the leafy tomato plant in my garden gets processed as “bunny” once my saccadic eye movements, taking in the huge quantity of data from a day outdoors in summer, recognizes something in the shadows that signals “rabbit?” and then filters out other, distracting data from my view.

At which point, behavioral habit kicks in and, like Mr. McGregor, I dash after Peter with a hoe.

At sundown

The disintegrating physical and mental situation of an elderly best-beloved recently has led me back (after a brief pause) to readings in neurology and consciousness. It has also led me to reflect on the tasks memory accomplishes for us and how the need to tell a story seems to reside deep in whatever “makes us human.” Many poems, perhaps most of them, are “inspired” by memories and a need to tell. So I will indulge myself by giving a narration here, and perhaps poems will follow later.

paintdaub copy

The best-beloved has been in and out of hospitals, rehabilitation centers, and so-called independent living placement and appears to have developed a very common but not-commonly-talked-about cognitive disarray, or hospital-induced delirium, that medical personnel call “sundowning” when it occurs in Alzheimer’s patients. But my patient does not have Alzheimer’s disease. Her meshing of realities must have been triggered by something else, but the possible factors are many. We may never figure out what it was that pitched her into delusion and lack of compassion, turning her into a person we barely know.

She took good care of her body. At 90, her physical self is in better shape than many people 20 years her junior. Her brain–and hence, her mind–has not stayed as healthy as the rest of her. Several small strokes deep in her brain began to alter not just her gait but her personal focus. Long years of hearing loss no doubt altered how her brain processes input. The reading I have been doing (most recently Carr’s The Shallows, Sacks’ On the Move, and Damasio’s Looking for Spinoza) indicates that the human brain is “plastic” but not necessarily “elastic.” It can modify in response to damage or training, but that does not mean it will spring back to the way it was before. In extreme old age, the process of adaptation slows. The brain becomes less resilient. For reasons no one really understands–a host of possible culprits includes hormones, glutamates, serotonin production, medicines, genetic predispositions, and environmental factors among others (a perfect storm…)–persons who have been sharp and cogent may suddenly experience delusions, often leading to paranoia, confusion, loss of affect, lack of social filters, violent and contrary behavior.

And we ask, “What happened to the soul I love?”

If we believe in souls, we have faith that somewhere under the changeling is the best-beloved. In flashes, she may return to us. If we believe that the brain is the person, the transition from best-beloved to aggressive complainer is harder to accept. Damasio seems to believe the brain is the person. I find it hard to agree with him fully, though I have been learning a lot about neurology in the process.

Metaphors or analogies for the situation seldom seem, to me, quite to capture the wrenching feeling I have when encountering sundowning. The idea of disintegration seems inappropriate in this case, because she recalls who we are and her mind is not collapsing so much as morphing in unaccountable ways. Threads unraveling? No, not really; the metaphor of a quilt coming undone, maybe, or an intricately-woven tapestry shredded apart–but that’s far too simplistic.

Think of the mind: it encompasses the brain with its regions for motor, somatosensory, auditory, and visual processing; the body, which takes in those physically-produced inputs; memories; thoughts; feelings, which are thoughts spurred by emotions; and a host of complex inter-relationships we cannot even begin to map. Somewhere in all of this is the person, the “self.” At least, as far as we have so far been able to speculate (though not everyone agrees; see my post on Hofstadter & Parfit. Parfit suggests personal identity is an invalid construct).

Perhaps an environmental analogy would suffice, being complex enough for comparison. She is the planet Earth, aging and adaptable, but not endlessly adaptable; her healthy balance has been thrown off by things she may not have had any control over. In whole regions, she becomes inhospitable. Poisoned. Dry. Hot. Overrun with invasives. She seems not to like us anymore, but that is not what’s going on at all. In fact, she’s dying.

Maybe that’s taking the metaphor too far. But in difficult times, one reaches far. There is hope she may recover at least some of her Self, and in the meantime, we have stories in which she plays a role. Mnemosyne–awaken in the consciousness of those who know her. Telling the stories is a step toward letting go.

 

Change the mind

“The only job of the poet is to destabilize and expand language. This is how poetry changes the world—not by grand ambition or the lauding of critics. It takes the plodding, unending effort of many to alter line by line, phrase by phrase, word by word the way we describe ourselves and everything around us. This is how we change perception. This is how we change the mind.”  —Jaswinder Bolina (in Poetry Foundation: “The Writing Class”  )

Words to mull over. How do we change perception? Is the change of mind correlated with a change in mind–potential alterations of the brain’s structure or synaptic system? If we destabilize language, do we necessarily alter perception?

Although the book is not an easy read, Starr’s Feeling Beauty: The Neuroscience of Aesthetic Experience offers interdisciplinary research into how the brain may be altered by powerful aesthetic experience, or at any rate, how the brain responds to these experiences in ways that lead some researchers to believe the brain can be changed by art. Not just by those who create art, but by those who encounter it.

I encountered Bolina’s essay (see link above) a week or so after I completed reading Starr’s book, and the consilience–to borrow a scientific term–seemed powerful. The ideas have not yet cohered in my own mind, but perhaps in time I will have more to say on this topic.

Meanwhile, I revel in the juicy possibilities of changing mind through art.

 

 

 

 

More on poetry & the brain

I remain pretty busy with the October poetry workshop and mid-term evaluations, so I’m going to cheat a bit by adding a link to Poet’s Quarterly, which is featuring in this issue one of my brief essays.

Click on this sentence to take you there. (Probably there is a way to embed the post, but I have not quite figured that out and lack the time today to look into it.)
