Whence insight?…
New research published in BMC Psychology suggests that the structural wiring of the brain may play a significant role in how people solve problems through sudden insight. The study indicates that individuals who frequently experience “Aha!” moments tend to have less organized white matter pathways in specific language-processing areas of the left hemisphere. These findings imply that a slightly less rigid neural structure might allow the brain to relax its focus, enabling the unique connections required for creative breakthroughs.
For decades, scientists have studied the phenomenon of insight, which occurs when a solution to a problem enters awareness suddenly and unexpectedly. This is often contrasted with analytical problem solving, which involves a deliberate and continuous step-by-step approach.
While previous studies using functional MRI and EEG have mapped the brain activity that occurs during these moments, there has been little understanding of the underlying physical structure that supports them. The researchers behind the new study aimed to determine if stable differences in white matter—the bundles of nerve fibers that connect different brain regions—predict an individual’s tendency to solve problems via insight.
“For over two decades, neuroscience has mapped what happens in the brain during these moments using EEG and fMRI. We know from prior research that insight feels sudden, tends to be accurate, and involves distinct functional activation patterns — including a burst of activity in the right temporal cortex just before the solution reaches awareness,” said study authors Carola Salvi of the Cattolica University of Milan and Simone A. Luchini of Pennsylvania State University.
“But one major question remained open: what structural features of the brain might make some people more likely to experience insight in the first place?”
“Most previous white matter studies of creativity did not specifically focus on Aha! experiences. They measured how many problems people solved, or how creatively, not how they solved them (with or without these sudden epiphanies). Yet insight and non insight solutions are phenomenologically and neurally distinct processes.”
White matter acts as the communication infrastructure of the brain, transmitting signals between distant regions. To examine this structure, the researchers employed a technique called Diffusion Tensor Imaging (DTI). This method tracks the movement of water molecules within brain tissue.
“We wanted to know whether stable white matter microstructure — the brain’s anatomical wiring — differs depending on whether someone tends to solve problems through sudden insight or through deliberate step-by-step reasoning (non insight solutions),” Salvi and Luchini explained. “Diffusion tensor imaging (DTI) allowed us to examine this structural dimension directly.”…
… The findings offered a counterintuitive perspective on brain connectivity. The analysis revealed that participants who solved more problems via insight exhibited lower fractional anisotropy in the left hemisphere’s dorsal language network. This network includes the arcuate fasciculus and the superior longitudinal fasciculus, pathways that connect brain regions responsible for language production, comprehension, and semantic processing.
“One striking finding was that people who more frequently experienced insight showed lower fractional anisotropy in specific left-hemisphere dorsal language pathways, including parts of the arcuate fasciculus and superior longitudinal fasciculus,” Salvi and Luchini told PsyPost.
“At first glance, that might sound counterintuitive. Fractional anisotropy is often interpreted as reflecting the coherence or organization of white matter pathways. In many cognitive domains, higher fractional anisotropy is associated with better performance.”
“But insight may operate differently. The left hemisphere is typically involved in focused, fine-grained semantic processing — narrowing in on dominant interpretations of words and concepts. The right hemisphere, by contrast, is thought to support broader, ‘coarse’ semantic coding — integrating more distantly related ideas. Slightly lower fractional anisotropy in left dorsal language pathways may reflect a system that is less tightly constrained by dominant interpretations.
“In other words, it may allow a partial ‘release’ from habitual patterns of thought and it is in line with other studies where lesions in the left frontotemporal regions have been shown to increase artistic creativity,” Salvi and Luchini continued. “Taken together, these findings imply that left hemispheric regions play a regulatory role in creativity and that their disruption lifts this constraint, thus promoting novel ideas.”…

As we ruminate on revelation, we might recall that it was on this date in 1939 that the college fad of swallowing live goldfish began at Harvard: a freshman named Lothrop Withington, Jr., reportedly bragged to his friends that he had once eaten a live fish. They bet him 10 bucks he couldn’t do it again. Perhaps because he was running for Class President, he took the challenge…
The moment of truth came on March 3, within the hallowed halls of Harvard. Standing in front of a crowd of grinning classmates and at least one Boston reporter, Withington dropped an ill-fated 3-inch goldfish into his mouth, gave a couple chews and swallowed. “The scales,” he later remarked, “caught a bit on my throat as it went down.”
Soon the word spread to other colleges. Other students began to take up the challenge, swallowing more and more goldfish each time to top the last record. By the time students were downing dozens of live, wriggling goldfish to uphold their school’s honor, the Massachusetts legislature stepped in and passed a law to “preserve the fish from cruel and wanton consumption.” The U.S. Public Health Service began to issue warnings that the goldfish could pass tapeworms and disease to swallowers. Within a few months of its start, the fad died out.

The estimable Jill Lepore on her strategy for coping during the “First 100 Days”…
On the twentieth of January, the year of our Lord 2025, Donald Trump’s one hundred days began.
Thank you. Thank you very much, everybody. (Applause.) Wow. Thank you very, very much.
I read his second Inaugural Address early the next morning in bed, curled, bent to the glow of an iPhone in dark mode, a morning ritual that always feels like sin.
From this day forward, our country will flourish and be respected again all over the world.
Then, dutifully, I scrolled through the Day One executive orders:
A full, complete and unconditional pardon . . . offenses related to events that occurred at or near the United States Capitol on January 6, 2021 . . .
. . . the privilege of United States citizenship does not automatically extend to persons born in the United States . . .
. . . establishes the Department of Government Efficiency . . .
. . . eliminate the “electric vehicle (EV) mandate” . . .
. . . directing that it officially be renamed the Gulf of America.
The Day One executive orders included—and depended on—the President’s formal, executive declarations of not one, not two, but three national emergencies: an immigration emergency, an energy emergency, and a terrorism emergency. There was also the Donald-Trump-is-President-again emergency.
I buried my phone under my pillow and closed my eyes. Blindly, I reached over to my nightstand and groped for a book. I pulled off the stack the first of the Penguin Little Black Classics, a collection of slender paperbacks that I’d been meaning to read, each as thin and sleek as my phone, bound in black, with white type on a plain cover. Dark mode.
No. 1, Giovanni Boccaccio, “Mrs Rosie and the Priest,” is described on the back cover as “bawdy tales of pimps, cuckolds, lovers and clever women from the fourteenth-century Florentine masterpiece The Decameron.” The book opened like a flower, like a hinge, like a butterfly, like a pair of hands in blessing. I turned to the first page:
I was told some time ago about a young man from Perugia called Andreuccio, the son of a certain Pietro and a horse-dealer by trade.
My heart leapt. I had found my doomscrolling methadone. With five hundred gold florins in his bag, Andreuccio set off for Naples. And I made a vow to read one volume of the Penguin Little Black Classics each morning in bed, matins, for a hundred days. Two and a half times Lent. In case of emergency, break open a book…
And read she did– each morning, before the day’s decrees, she turned to a slim book, hoping for sense, or solace… and happily for us, she kept a journal: “A Hundred Classics to Get Me Through a Hundred Days of Trump,” from @newyorker.com. (In the event of a paywall: an archived version.)

As we pursue perspective, we might recall that it was on this date in 1968 that Aretha Franklin impatrted some timeless advice: she released “Think” (which she had co-written with Ted White), the first single from her upcoming album Aretha Now. It reached No. 7 on the Billboard Hot 100, Franklin’s seventh top 10 hit in the United States and hit number 1 on the magazine’s Hot Rhythm & Blues Singles, her sixth single to top that chart.

Nonbeing belongs to that category of concepts that seem self-evident and self-explanatory, but as FT explains, it has perplexed philosophers for ages…
Bertrand Russell’s 1951 obituary for Ludwig Wittgenstein is only a few paragraphs long, and the second consists largely of a single pointed anecdote:
Quite at first I was in doubt as to whether he was a man of genius or a crank…. He maintained, for example, at one time that all existential propositions are meaningless. This was in a lecture room, and I invited him to consider the proposition: “There is no hippopotamus in this room at present.” When he refused to believe this, I looked under all the desks without finding one; but he remained unconvinced.
The exchange is typical of the two philosophers’ relationship: Russell’s proper British demeanor was frequently ruffled by the Austrian’s dry humor. But it also illustrates two general approaches to philosophy: one that takes pleasure in complexities, absurdities, and ironies, and one that takes pleasure in resolving them. Just as Wittgenstein surely realized that there was no hippopotamus in the room, Russell surely realized that Wittgenstein’s objection could not be dispelled empirically by looking under each desk. At stake was not a fact of perception but the epistemological status of negation—the philosophical meaning and value of assertions about nothing.
Nothing, or nonbeing, belongs to that category of concepts—like being, space, and consciousness—that seem self-evident and self-explanatory to most people most of the time, but that for philosophy have been objects of deepest perplexity and millennia-long dispute. It’s a little like breathing, which happens automatically until we stop to think about it. To most of us, Russell’s statement “There is no hippopotamus in this room” is both easily understood and easily verified. We think we know what it means, and most of us would only need a quick look around to affirm or deny the proposition.
But here our troubles begin. If you look around the room and don’t see a hippopotamus, presumably you do still see something: some kind of perception or sensory data is reaching your consciousness, which allows you to make a judgment. What is it that you do see when you see a hippopotamus not being there? Are you perceiving a nonbeing, seeing a particular thing whose nature is absence, or are you not perceiving any being, seeing no “thing” at all? When you see a hippopotamus not being there, are you also seeing a whale and a lion and a zebra not being there? Is every room full of all the things that aren’t in it?
From an evolutionary perspective, one predator not being there is just as good as any other predator not being there, but dialectics and logic are a little more particular. If every possible animal is not there at the same time, what specific truth-value can the assertion “There is no hippopotamus in this room” possibly have? Hence Wittgenstein’s insistence, facetious or not, that all existential propositions are meaningless. In this manner the complications and implications of nothing spill into every area of philosophical inquiry, and we quickly come to sympathize with Aristophanes’ brutal satire of philosophers in The Clouds:
Socrates: Have you got hold of anything?
Strepsiades: No, nothing whatever.
Socrates: Nothing at all?
Strepsiades: No, nothing except my tool, which I’ve got in my hand.

As we analyze absence, we might send mindful birthday greetings to Mahasi Sayadaw; he was born on this date in 1904. A Burmese Theravada Buddhist monk and meditation master, he had a significant impact on the teaching of vipassanā (insight) meditation in the West and throughout Asia.
