Mark Twain “Dared to State Things That Others Only Thought”

I have read three of Ron Chernow’s massive biographies, the ones on Rockefeller, Washington, and Hamilton. Because they are massive, reading them takes a long time, at least for a slow reader like me. But I learned a lot that is important or useful from them, especially the ones on Rockefeller and Hamilton. Because I am an admirer of both Chernow and Twain, I look forward to also reading Chernow’s biography of Twain.

(p. C7) More than a century after his death, Mark Twain remains one of the most recognizable voices in American literature—the author of “The Adventures of Tom Sawyer” (1876), “Life on the Mississippi” (1883) and “Adventures of Huckleberry Finn” (1884), the latter among the most consequential novels ever written in English and possibly (if you believe Ernest Hemingway) the source of American literature itself.

. . .

In his biography of the famed satirist, Ron Chernow tracks, with patience and care, Twain’s journey over nearly eight tumultuous decades. Mr. Chernow’s tale is enlivened by blazing quotes from Twain’s prodigious interviews, diaries and letters.  . . .  The quotes tend to burn a hole in the page, and it’s difficult for a biographer to recover. Mr. Chernow, whose lives of George Washington, Alexander Hamilton and Ulysses S. Grant are revered for their sound scholarship, clear writing and strong narrative drive, weaves Twain’s sizzling remarks almost seamlessly into his own narrative.

We watch as Twain lunges from coast to coast, rolling up and down the Mississippi (as a riverboat pilot in his early days), moving from country to country, writing books and articles, investing large sums in various hair-brained schemes.

. . .

This was, in Twain’s own phrase, the Gilded Age. He admired, even idealized, those who made huge sums of money through their entrepreneurial energy and acumen. He had the same energy, but he didn’t have the right vehicles for speculation nor the business sense to make his investments pay off. As Mr. Chernow observes, Twain could well have enjoyed an easy life of writing and giving lectures, having married a wealthy woman and published several bestsellers. “Instead, he had started a publishing house and financed a typesetter”—the Paige Compositor, which was supposed to replace manual typesetting but failed spectacularly because of engineering flaws—“before he had the expertise or requisite fortune to bring them to completion.” His expenses soon dwarfed his income and he was forced to abandon his Hartford mansion, never to return.

. . .

Twain was “a man who professed to be chronically lazy,” says Mr. Chernow, yet he left behind him a vast portfolio of writings that included 30 books, several thousand magazine articles and some 12,000 letters. “Mark Twain had not only moved people to laughter and tears with his books,” Mr. Chernow writes, “but had challenged them with unorthodox views as he ventured out from his safe cubbyhole as the avuncular humorist. He had dared to state things that others only thought.” It’s because of this bravery, and his peerless gift for expression, that we still value him and will never stop reading his books, which never grow old.

Girls Who Are Skilled in Both STEM and Non-STEM Fields, Usually Prefer Non-STEM Fields

Gender discrimination is not the only explanation for there being more men than women in STEM jobs, according to the research summarized in the passages quoted below.

(p. C3) Scores of surveys over the last 50 years show that women tend to be more interested in careers that involve working with other people while men prefer jobs that involve manipulating objects, whether it is a hammer or a computer. These leanings can be seen in the lab, too. Studies published in the Personality and Social Psychology Bulletin in 2016, for example, found that women were more responsive to pictures of people, while men were more responsive to pictures of things.

Consistent with what men and women say they want, the STEM fields with more men, such as engineering and computer science, focus on objects while those with more women, such as psychology and biomedicine, focus on people.

Given the push to get more people—and especially more girls—interested in STEM, it is worth noting that talented students of both sexes tend to avoid a career in math or science if they can pursue something else. STEM jobs aren’t for everyone, regardless of how lucrative they may be.

A study of more than 70,000 high-school students in Greece, published in the Journal of Human Resources in 2024, found that girls on average outperformed boys in both STEM and non-STEM subjects but rarely pursued STEM in college if they were just as strong in other things. A study of middle-aged adults who had been precocious in math as teens, published in the journal Psychological Science in 2014, found that only around a quarter of the men were working in STEM and IT.

Large-scale studies around the world show that women are generally more likely than men to have skills in non-STEM areas, while men who are strong in math and science are often less skilled elsewhere. But while everyone seems to be concerned about whether girls are performing well in STEM classes, no one seems all that troubled by the fact that boys are consistently underperforming in reading and writing.

Vinyl LP Records Have Been Mostly Replaced, but in Kansas Not Completely Destroyed

In my Openness book, I argue that Schumpeter’s phrase “creative destruction” misleads by overemphasizing the extent of destruction in the process of breakthrough innovation, so I prefer to call the process “innovative dynamism.” A new innovation is often better than the old in many, but not all, traits. A minority of people who put heavy weight on the traits where the old product is better, will still prefer the old product. If the minority is large enough, and willing to pay enough for their preference, then there will be enough demand for the old product to remain in production, rather than be fully replaced (i.e., destroyed).

Illustrating my point, The New York Times ran two full pages on Chad Kassem, a Kansas entrepreneur who is working hard, with some success, at making higher quality vinyl LP records. He has 114 employees and annual revenue of over $1 million.

He is even introducing incremental innovations to the old product: (p. 6) “Kassem hired veterans of the record-making business and indulged their ideas for modernizing a process that (p. 7) had barely changed since the 1970s. Among other innovations, they introduced computerized controls and found ways to regulate the fluctuating temperature of vinyl in the presses.”

Muriel Bristol Was Allowed to Act on What She Knew but Was Unable to Prove or Explain

Muriel Bristol knew that tea tasted better when the milk was poured in first, than when it was poured in after the tea. She knew it but couldn’t prove it and didn’t know why it was true. The world is better when more of us, more often, can act on what we know, but what we can neither prove nor explain. Too often regulations restrict the actions of entrepreneurs to what they can prove and explain, e.g., in the firing of employees.

This slows and reduces efficiency and innovation (not to mention freedom).

(p. C8) [Adam] Kucharski, a mathematically trained epidemiologist, says that the rigor and purity of mathematics has imbued it with extraordinary rhetorical power. “In an uncertain world, it is reassuring to think there is at least one field that can provide definitive answers,” he writes. Yet he adds that certainty can sometimes be an illusion. “Even mathematical notions of proof” are “not always as robust and politics-free as they might seem.”

. . .

. . ., proving what is “obvious and simple” isn’t always easy. Kucharski offers the delightful example of Muriel Bristol, a scientist who always put the milk in her cup before pouring her tea, because she insisted it tasted better. In the 1920s, a skeptical statistician designed a blind taste test to see if Bristol could distinguish between cups of milk-then-tea and cups of tea-then-milk. Bristol got all of them right. In 2008, the Royal Society of Chemistry reported that when milk is poured into hot tea, “individual drops separate from the bulk of the milk” and allow “significant denaturation to occur.” The result is a burnt flavor. Eighty years after Bristol was statistically vindicated, she was chemically vindicated too.

A Rare Antibody in James Harrison’s Blood Protected the Lives of 2.4 Million Australian Babies

I recently purchased from Amazon, but have not read, Good Blood, which describes the discovery of a cure, and the struggle for acceptance of the cure, for the RH disease sketched in the passages quoted below. The disease affected my family, but I am not sure I remember exactly how. I am Rh positive and I think my mother was Rh negative. I think with each child after me, there was increasing risk and worry of possible bad health effects.

According to the Amazon summary for Good Blood, the book also describes the devotion of master blood donor James Harrison, whose recent obituary is quoted below.

Starting at least in the 1960s medical experts were often optimistic that future medical advances would come from designer chemicals enabled by scientific advances in our knowledge of chemistry and biological processes. Taxpayer funding was devoted to that approach in Nixon’s War on Cancer. But fewer medical advances have come from that approach than hoped, and more advances than expected have continued to come from the evolved usable chemicals (sometimes poisons, sometimes antibodies) of plants, animals, and exceptional human beings like Mr. Harrison.

Mao is often misquoted as saying ‘Let a thousand flowers bloom,’ but someone should say it (at least if the cost of planting the flowers is not too high).

(p. A25) James Harrison did not much care for needles. Whenever he donated plasma, he would look away as the tip went into his arm.

But Mr. Harrison was one of the most prolific donors in history, extending his arm 1,173 times. He may have also been one of the most important: Scientists used a rare antibody in his plasma to make a medication that helped protect an estimated 2.4 million babies in Australia from possible disease or death, medical experts say.

“He just kept going and going and going,” his grandson Jarrod Mellowship said in an interview on Monday [March 3, 2025]. “He didn’t feel like he had to do it. He just wanted to do it.”

. . .

Mr. Harrison’s plasma contained the rare antibody anti-D. Scientists used it to make a medication for pregnant mothers whose immune systems could attack their fetuses’ red blood cells, according to Australian Red Cross Lifeblood.

Anti-D helps protect against problems that can occur when babies and mothers have different blood types, most often if the fetus is “positive” and the mother is “negative,” according to the Cleveland Clinic. (The positive and negative signs are called the Rhesus factor, or Rh factor.)

In such cases, a mother’s immune system might react to the fetus as if it were a foreign threat. That can lead babies to develop a dangerous and potentially fatal condition, hemolytic disease of the fetus and newborn, which can cause anemia and jaundice.

. . .

In Australia, scientists from the Walter and Eliza Hall Institute of Medical Research in Melbourne are working to create a synthetic version of the drug using what some have called “James in a Jar,” an antibody that can be made in a lab.

But for now, human donors are essential: The anti-D shots are made with donated plasma, and Mr. Harrison was one of about 200 donors among the 27 million people in Australia, Lifeblood said.

. . .

Mr. Harrison knew the importance of his work firsthand. At 14, he needed a lot of blood transfusions during a major lung surgery. The experience inspired him to donate and encourage others to donate, too.

Private Sector Succeeds Where Public Sector Fails at Operating a Successful Passenger Train

The New York Times recently ran a surprising (for them) article highlighting the success of the privately owned Brightline passenger railroad on the east coast of Florida. The Times contrasts the private success of Brightline with the public failures of Amtrak and California’s mostly undone proposed bullet train. Amtrak ran an operating deficit of over $700 million in 2024. The long-planned, barely-begun, pared-back California bullet train is now estimated to require over $100 billion to reach completion.

Maybe Brightline succeeds because the private sector allows entrepreneurs to use what Deirdre McCloskey calls trade-tested innovation to pursue their projects.

The private sector allows innovative dynamism.

A World with No Tariffs, No Barriers, No Subsidies

Art Laffer and Stephen Moore had an op-ed a few weeks ago in which they encouraged Donald Trump to be the best version of himself on the tariff and trade issue. Trump has made inconsistent statements on tariffs and trade. Sometimes his goal seems to be to seek long-term tariffs that bring in substantial revenue. But his best version seeks a mutual reduction in tariffs to zero–a world of free trade, which when combined with deregulation and downsizing of government will allow entrepreneurs to innovate and trade so that we all flourish.

The best version of Trump is the one who spoke the following words in 2018 at a meeting of the Group of Seven in Quebec:

“No tariffs, no barriers. That’s the way it should be. And no subsidies. I even said, ‘no tariffs.’ . . . Ultimately, that’s what you want. You want tariff-free, no barriers and you want no subsidies.” (Trump as quoted in Laffer and Moore 2023, p. A17)

Killer Conservationists

I have not read Cull of the Wild: Killing in the Name of Conservation, but from its title and description it sounds like it documents an important and under-appreciated point. The point is that to “conserve” some species, so-called “conservationists” sometimes kill large numbers of the members of other species. (See, e.g., my blog entry on west coast “conservationists” killing massive numbers of one kind of brown owl in order to preserve a similar species of brown owl.)

Species ebb and flow. This was true before humanity arrived and is still true now. “Conservationists” anoint some species as “indigenous” and others as “invasive,” which can only be done if some particular arbitrary moment is taken as the one that must be preserved or returned-to.

The book that looks promising is:

Pasteur Saw That “Germs Were Everywhere in the Air”

The passages quoted below show how Pasteur respected his audience by finding a clear and compelling way to communicate that “germs” float in the air. The essay quoted below is adapted from Zimmer’s recently released Air-Borne book.

In other parts of Air-Borne, Zimmer discusses how the W.H.O. and the C.D.C. ignored the implications of the findings of Pasteur and others, relevant to the air-borne (aerosol) spread of diseases such as Covid-19.

(p. D8) On the evening of April 7, 1864, in an amphitheater filled with Parisian elites, Pasteur stood surrounded by lab equipment and a lamp to project images on a screen. He told the audience it would not leave the soiree without recognizing that the air was rife with invisible germs. “We can’t see them now, for the same reason that, in broad daylight, we can’t see the stars,” he said.

At Pasteur’s command, the lights went out, save for a cone of light that revealed floating motes of dust. Pasteur asked the audience to picture a rain of dust falling on every surface in the amphitheater. That dust, he said, was alive.

Pasteur then used a pump to drive air through a sterile piece of cotton. After soaking the cotton in water, he put a drop under a microscope. He projected its image on a screen for the audience to see. Alongside soot and bits of plaster, they could make out squirming corpuscles. “These, gentlemen, are the germs of microscopic beings,” Pasteur said.

Germs were everywhere in the air, he said — kicked up in dust, taking flights of unknown distances and then settling back to the ground, where they worked their magic of fermentation. Germs broke down “everything on the surface of this globe which once had life, in the general economy of creation,” Pasteur said.

“This role is immense, marvelous, positively moving,” he added.

The lecture ended with a standing ovation. Pasteur’s hunt for floating germs elevated him to the highest ranks of French science.

“Effort Means That You Care About Something”

In my Openness book, I argue that we should allow each other the freedom to choose intensity over work-life balance. David Brooks is sometimes thought-provoking and eloquent, for instance in the passages quoted below where he defends intensity.

One question that Brooks discusses elsewhere in his essay is: how do you find your “passion,” your “misery,” your “vocation”? He tries but after reading his answers, I think the mystery mostly remains. The best answer to this question that I have found is in a book by John Chisholm called Unleash Your Inner Company. Chishom suggests that you should apply yourself to something worth doing, and work to do it better. If you do that, he suggests, you are likely to eventually find you increasingly care about what you are doing.

(p. 9) My own chosen form of misery is writing. Of course, this is now how I make a living, so I’m earning extrinsic rewards by writing. But I wrote before money was involved, and I’m sure I’ll write after, and the money itself isn’t sufficient motivation.

Every morning, seven days a week, I wake up and trudge immediately to my office and churn out my 1,200 words — the same daily routine for over 40 years. I don’t enjoy writing. It’s hard and anxiety-filled most of the time. Just figuring out the right structure for a piece is incredibly difficult and gets no easier with experience.

I don’t like to write but I want to write. Getting up and trudging into that office is just what I do. It’s the daily activity that gives structure and meaning to life. I don’t enjoy it, but I care about it.

We sometimes think humans operate by a hedonic or utilitarian logic. We seek out pleasure and avoid pain. We seek activities with low costs and high rewards. Effort is hard, so we try to reduce the amount of effort we have to put into things — including, often enough, the effort of thinking things through.

And I think we do operate by that kind of logic a lot of the time — just not when it comes to the most important things in our lives. When it comes to the things we really care about — vocation, family, identity, whatever gives our lives purpose — we are operating by a different logic, which is the logic of passionate desire and often painful effort.

. . .

. . . I have found that paradoxically life goes more smoothly when you take on difficulties rather than try to avoid them. People are more tranquil when they are heading somewhere, when they have brought their lives to a point, going in one direction toward an important goal. Humans were made to go on quests, and amid quests more stress often leads to more satisfaction, at least until you get to the highest levels. The psychologist Carol Dweck once wrote: “Effort is one of the things that gives meaning to life. Effort means that you care about something.”

All this toil is not really about a marathon or a newspaper article or a well-stocked shelf at the grocery store. It’s about slowly molding yourself into the strong person you want to be. It’s to expand yourself through challenge, steel yourself through discipline and grow in understanding, capacity and grace. The greatest achievement is the person you become via the ardor of the journey.

. . .

So, sure, on a shallow level we lead our lives on the axis of pleasure and pain. But at the deeper level, we live on the axis between intensity and drift. Evolution or God or both have instilled in us a primal urge to explore, build and improve. But life is at its highest when passion takes us far beyond what evolution requires, when we’re committed to something beyond any utilitarian logic.

Animals Consume Effective Medicines Without Spending Billions on Phase 3 Clinical Trials

Animals are free to self-medicate and apparently often do so effectively. Isn’t it ironic that our government F.D.A. restricts the freedom of humans to self-medicate?

(p. A13) . . . as Jaap de Roode reveals in “Doctors by Nature: How Ants, Apes, and Other Animals Heal Themselves,” many animals seek out substances to relieve illnesses or battle parasites that drag their health down: . . .

Mr. de Roode, a biology professor at Emory University, chronicles animal self-medication in everything from caterpillars and bees to pigs and dolphins. The drugs take the form of minerals, fungi and especially plants. Often, the drug is ingested for therapeutic reasons, as when chimps eat Velcro-like leaves to scour parasitic worms from their intestines. Many creatures also take drugs prophylactically, to prevent disease. The feline love of catnip, Mr. de Roode suggests, is probably an evolutionary adaptation: The plant deters disease-carrying mosquitoes, so cats with a taste for it ended up more equipped for survival.

. . .

Many plants produce chemicals called alkaloids that taste foul and cause other unpleasant sensations, but can also fight off parasites. After noticing that woolly bear caterpillars infested with fly maggots tend to seek out alkaloid-rich plants, scientists documented—by threading tiny wires into the caterpillars’ mouths—that the infected critters’ taste buds fired far more often when eating these plants than did the taste buds of the uninfected. The bugs’ sensory perception changed to make drugs more attractive. If the consumption of some irregular substance leads to a drop in infection load and alleviates negative symptoms, then, Mr. de Roode convincingly argues, animals are indeed using medicine. Caterpillar, heal thyself.

. . .

Humans can benefit from studying animal medicine, too. Most of our drugs are either plant compounds or derived from plant compounds. But researchers have systematically studied only a few hundred of the earth’s estimated tens of thousands of plant species. To guide researchers’ studies, scientists could note which ones animals consume and concentrate on those. Let Mother Nature do the research and development for us.
