A Neurologist’s Tips to Protect Your Memory

Hope Reese in The New York Times:

As we age, our memory declines. This is an ingrained assumption for many of us; however, according to neuroscientist Dr. Richard Restak, a neurologist and clinical professor at George Washington Hospital University School of Medicine and Health, decline is not inevitable. The author of more than 20 books on the mind, Dr. Restak has decades’ worth of experience in guiding patients with memory problems. “The Complete Guide to Memory: The Science of Strengthening Your Mind,” Dr. Restak’s latest book, includes tools such as mental exercises, sleep habits and diet that can help boost memory.

Yet Dr. Restak ventures beyond this familiar territory, considering every facet of memory — how memory is connected to creative thinking, technology’s impact on memory, how memory shapes identity. “The point of the book is to overcome the everyday problems of memory,” Dr. Restak said. Especially working memory, which falls between immediate recall and long-term memory, and is tied to intelligence, concentration and achievement. According to Dr. Restak, this is the most critical type of memory, and exercises to strengthen it should be practiced daily. But bolstering all memory skills, he added, is key to warding off later memory issues.

Wednesday Poem

The Innumerable

The innumerable live in us;
when I think or feel, I do not know
who it is thinks or feels.
I am merely a place
of feeling or thought.
I have more souls than one.

There are more I’s than myself.

I exist nonetheless
indifferent to them all.
I silence them: I speak.

The conflicting impulses
of what I feel or do not feel
dispute inside who I am.

I ignore them. They dictate nothing
to the one I know. I write.

Søren Kierkegaard’s Theory Of Despair

Clare Carlisle at The Nation:

Even though Kierkegaard treats despair as a spiritual and existential condition rather than just a psychological state, The Sickness Unto Death sparkles with psychological insight. Especially compelling is his diagnosis of the different forms of despair that arise from an imbalance between the various pairs that make up the human synthesis (those first folds in our sheets of paper). Too much necessity, and we lose all imagination and hope—we cannot breathe; too much possibility, and we float airily, ineffectually, above our own lives. Too much finitude, and we lose ourselves in trivial things; too much infinitude, and we’re disconnected from the world. Since life is so rarely in balance, despair is the inevitable state—but understanding this, for Kierkegaard, opens up a renewed perspective on how to live with this inevitability.

The psychology of despair also helps illuminate its politics and sociology. Kierkegaard saw the fact that we are disconnected from ourselves, and from God, as not just an individual problem but an indictment of the modern age.

Postcards from Elizabeth Bishop

Langdon Hammer at The Paris Review:

Elizabeth Bishop delighted in the postcard. It suited her poetic subject matter and her way of life—this poet of travel who was more often on the move than at home, “wherever that may be,” as she put it in her poem “Questions of Travel.” She told James Merrill in a postcard written in 1979 that she seldom wrote “anything of any value at the desk or in the room where I was supposed to be doing it—it’s always in someone else’s house, or in a bar, or standing up in the kitchen in the middle of the night.”

Since her death in 1979 and the publication of her selected correspondence, Bishop has become known as one of the great modern-day letter-writers. And yet inevitably something is lost when an editor transcribes a letter to prepare it for print: the quality of the correspondent’s hand (or the model of her typewriter), the paper used, cross-outs and typos, and everything else that fixes the letter in time and space. When it comes to a postcard, or a letter composed on a series of postcards (something Bishop enjoyed doing), we get none of the images, and even more is lost.

“The East India Company and the Politics of Knowledge” by Joshua Ehrlich

Soni Wadhwa at the Asian Review of Books:

Knowledge is power. This is a statement often made to reinforce the relentless pursuit of data, information and know-how to get ahead in business and technology. Scholarship or studiousness is seen as a virtue that can give one an edge over the others in the face of tough competition. With such a celebration of knowledge, it appears that anything can be legitimized if it is connected with knowledge creation or dissemination. In The East India Company and the Politics of Knowledge, Joshua Ehrlich examines a much stronger, to the point of being literal, historical connection between knowledge and power. 

The subject of his study is the late 18th- to mid-19th-century regime of the East India Company. The Company was questioned by Indian sovereigns as well as the British Parliament for its pretense to run Indian territory it captured as if it were a sovereign power. After all, they objected, it was absurd for a commercial entity to have any credentials for governance.

Ed Yong on revealing the hidden lives of animals

Patrick Barkham in The Guardian:

Why does the giant squid have eyes as large as a football? Why do more than 350 species of fish produce their own electricity? Why do dogs become more optimistic after two weeks of plentiful sniffing?

The mysteries and miracles of animal senses are revealed in this year’s winner of the £25,000 Royal Society Trivedi science book prize, which was announced on Wednesday.

An Immense World by Ed Yong is an epic exploration of the unique “umwelt” of other creatures, from tree hoppers to singing frogs, who sense the world in vastly different ways to humans. It is also a plea for greater empathy with other species.

Ethics has no foundation and that’s okay

Andrew Sepielli in Aeon:

Rather than focusing on how people and societies think and talk about morality, normative ethicists try to figure out which things are, simply, morally good or bad, and why. The philosophical sub-field of meta-ethics adopts, naturally, a ‘meta-’ perspective on the kinds of enquiry that normative ethicists engage in. It asks whether there are objectively correct answers to these questions about good or bad, or whether ethics is, rather, a realm of illusion or mere opinion.

Most of my work in the past decade has been in meta-ethics. I believe that there are truths about what’s morally right and wrong. I believe that some of these truths are objective or, as they say in the literature, ‘stance-independent’. That is to say, it’s not my or our disapproval that makes torture morally wrong; torture is wrong because, to put it simply, it hurts people a lot. I believe that these objective moral truths are knowable, and that some people are better than others are at coming to know them. You can even call them ‘moral experts’ if you wish.

Plant Of The Month: Quinoa

Matthew Turetsky at JSTOR:

This year marks the tenth anniversary of the International Year of Quinoa (IYQ), a celebratory initiative created by the Food and Agricultural Organization of the United Nations. At the inaugural 2013 IYQ, Evo Morales, then president of Bolivia, proclaimed that quinoa was “an ancestral gift from the Andes to the world.” The IYQ capitalized on the growing international interest in this Indigenous “superfood” to promote quinoa as a nutrient-dense, sustainable, and culturally rich alternative to common Western grains.

The Secretary General of the UN hoped that quinoa’s excellent environmental adaptability would enable farmers in places such as Kenya, India, and and Europe to start growing the indigenous Andean grain. Promoters, first agricultural scientists and then government officials and corporate marketers, transformed the reputation of quinoa into a “miracle food” that could solve intractable problems like global malnutrition and crop failure.

Jenny Erpenbeck’s Ambivalent Nostalgia

Ross Benjamin at The Point:

Born in East Berlin in 1967, Jenny Erpenbeck was 22 when the Wall that had divided her native city for her entire life fell. The socialist German Democratic Republic (GDR), the only country she had known, vanished overnight. By her own account, in the essays collected in Not a Novel: A Memoir in Pieces (2018), this historical rupture confronted her with fundamental questions about continuity and change, agency and contingency, borders and identity, liberation and loss. Although these questions have animated her fiction for more than twenty years, her most recent novel, Kairos (2021), is the first to be centered on how the radically transformative period of German reunification was experienced by those who found themselves, as she writes, “at home on the wrong side.”

The novel’s proximity to her own life is a long way from the more allegorical mode of storytelling that marked her early work, and yet in hindsight her path seems to have been leading inevitably to this juncture.

Why Trump’s Trials Should Be on TV

Amy Sorkin in The New Yorker:

On November 6th, Donald Trump emerged from a New York City courtroom, where he had testified in a civil trial alleging that he and others in the Trump Organization had committed fraud, and gave himself a great review. “I think it went very well,” he told reporters. “If you were there, and you listened, you’d see what a scam this is.” He meant that the case was a scam and not that his company was. “Everybody saw what happened today,” he went on. “And it was very conclusive.”

In truth, everybody didn’t see; the courtroom could seat just a few dozen spectators. There were two overflow rooms, but the closed-circuit feed shown in them went no farther—the trial was not televised. Afterward, New York’s attorney general, Letitia James, who was present, said that Trump had hardly put the matter to rest: “he rambled and he hurled insults.” There was a transcript, but, to assess Trump’s demeanor and tone, members of the public had to rely on the small number of people—journalists and lawyers, mostly—who witnessed them. And those reports differed, depending on, say, whether one watched MSNBC or Fox News.

The dissonance is about to get more extreme.

Mars Needs Insects

Sarah Scoles in The New York Times:

At first it was just one flower, but Emmanuel Mendoza, an undergraduate student at Texas A&M University, had worked hard to help it bloom. When this five-petaled thing burst forth from his English pea plant collection in late October, and then more flowers and even pea pods followed, he could also see, a little better, the future it might foretell on another world millions of miles from Earth. These weren’t just any pea plants. Some were grown in soil meant to mimic Mars’s inhospitable regolith, the mixture of grainy, eroded rocks and minerals that covers the planet’s surface. To that simulated regolith, Mr. Mendoza had added fertilizer called frass — the waste left after black soldier fly larvae are finished eating and digesting. Essentially, bug manure.

The goal for Mr. Mendoza and his collaborators was to investigate whether frass and the bugs that created it might someday help astronauts grow food and manage waste on Mars. Black soldier fly larvae could consume astronauts’ organic waste and process it into frass, which could be used as fertilizer to coax plants out of alien soil. Humans could eat the plants, and even food made from the larvae, producing more waste for the cycle to continue. While that might not ultimately be the way astronauts grow food on Mars, they will have to grow food. “We can’t take everything with us,” said Lisa Carnell, director for NASA’s Biological and Physical Sciences Division.

Tuesday Poem

Migrants

Strong boys to work on the farm.

The sad lot of migrants in the shadows.
The emaciated look of Mother Africa.
The uncertainties of the desert girls.

Look:
………….. Far away Aquarius has lost its flag.
………….. Multifaceted Africa lies down once again.
………….. Storm and night mingle in my heart,
………….. The flowing blood no longer human blood.

Look:
………….. In the distance, floodlit in the desert of Libya,
………….. The slave market of my fellow Blacks.
………….. At the heart of night men
………….. An outrage to humanity. This brother who is not me.

Strong boys to work on the farm.

In the murky apocalyptic night of the desert
The migrant hungers for virtue, dignity, justice.
In the meshes of emboldened and fierce smugglers
The solitary migrant dies
King of stone
Grain of sand in the auction sale.

On Yasmine El Rashidi’s “Laughter in the Dark” and Egyptian Festival Rap

Peter Holslin in the Los Angeles Review of Books:

Mahraganat (which means “festivals” in Arabic) is made primarily by self-taught young men from lower-class backgrounds, whose songs are considered brash, even vulgar, because they rap and sing openly about their lives with seldom a trace of modesty. Egypt’s canonical singers and composers from the 20th century, particularly Umm Kulthum, Abdel Halim Hafez, and Mohammed Abdel Wahab, possessed a virtuosic command of improvisational technique and classical repertoire. By comparison, mahraganat artists appeal first and foremost to friends from the block, weaving a unique lexicon of Arabic slang, boasts, insults, drug references, and sexual innuendo. The artists use Auto-Tune not only to add distortive, festive color to their rugged street anthems, but also for its manufacturer-intended purpose: to keep their voices in tune.

In the Gut’s ‘Second Brain,’ Key Agents of Health Emerge

Yasemin Saplakoglu in Quanta:

Breaking down food requires coordination across dozens of cell types and many tissues — from muscle cells and immune cells to blood and lymphatic vessels. Heading this effort is the gut’s very own network of nerve cells, known as the enteric nervous system, which weaves through the intestinal walls from the esophagus down to the rectum. This network can function nearly independently from the brain; indeed, its complexity has earned it the nickname “the second brain.” And just like the brain, it’s made up of two kinds of nervous system cells: neurons and glia.

Is OpenAI approaching AGI?

Tomas Pueyo, quoting Nathan Labenz in Uncharted Territories:

Nathan Labenz

I determined that GPT-4 was approaching human expert performance. Critically, it was also *totally amoral*. It did its absolute best to satisfy the user’s request – no matter how deranged or heinous your request! One time, when I role-played as an anti-AI radical who wanted to slow AI progress… GPT-4-early suggested the targeted assassination of leaders in the field of AI – by name, with reasons for each.

Today, most people have only used more “harmless” models, trained to refuse certain requests. This is good, but I wish more people had experienced “purely helpful” AI – it makes viscerally clear that alignment / safety / control do not happen by default.

The Red Team project that I participated in did not suggest that they were on-track to achieve the level of control needed. Without safety advances, the next generation of models might very well be too dangerous to release.

What is it like to be a crab?

Kristin Andrews in Aeon:

Twenty-five years ago, the burgeoning science of consciousness studies was rife with promise. With cutting-edge neuroimaging tools leading to new research programmes, the neuroscientist Christof Koch was so optimistic, he bet a case of wine that we’d uncover its secrets by now. The philosopher David Chalmers had serious doubts, because consciousness research is, to put it mildly, difficult. Even what Chalmers called the easy problem of consciousness is hard, and that’s what the bet was about – whether we would uncover the neural structures involved in conscious experience. So, he took the bet.

This summer, with much fanfare and media attention, Koch handed Chalmers a case of wine in front of an audience of 800 scholars. The science journal Nature kept score: philosopher 1, neuroscientist 0. What went wrong?
