The Garden of Earthly Delights

As I've suggested, I get burnt out with serious topics over time. This is why I return to fiction, poetry or art periodically. Of course, I also get burnt out with the arts, so this is sort of a never-ending cycle. I just read Hieronymus Bosch: Time and Transformation in The Garden of Earthly Delights, by Margaret D. Carroll, which is a detailed discussion of that painting. Carroll is an academic, so her writing suffers accordingly, but the book is very well-illustrated with details from the painting, and that alone makes it worthwhile. For those who want to see the painting, she recommends websites such as this, where you can view the entire painting and details better than you would be able to even if you visited it at the Museo Nacional del Prado, where it is exhibited.  

Hieronymus Bosch was a Dutch painter who lived from approximately 1450 to 1516. Little is known about his life other than the paintings that are attributed to him. It is thought that The Garden of Earthly Delights may have been commissioned by Henry III (count of Nassau) and was painted approximately between 1490 and 1510. This is one of the great paintings of the Northern Renaissance, and I have been interested in it for many years. Bosch was preceded by Jan van Eyck (1390-1441) and was a contemporary of Albrecht Dürer (1471-1528); he was followed by Pieter Bruegel the Elder (?-1569). To me, the Dutch painters were some of the best ever, culminating with Johannes Vermeer (1632-1675). Although the artists of the Italian Renaissance usually get more attention, in my opinion van Eyck, Bosch and Bruegel the Elder are much more interesting. This may be partly because the Northern Renaissance was accompanied by the Reformation, and Bosch, Bruegel and Dürer's lives overlapped with that of Martin Luther. I think that the pervasive influence of the Roman Catholic Church in Southern Europe thwarted both intellectual and artistic evolution, perhaps for centuries.

The Garden of Earthly Delights is a triptych, or three-paneled painting, of a style that was originally used for altar pieces in churches. They often read from left-to-right, starting with the Garden of Eden on the left, the origin of sin in the center, and apocalypse on the right. Bosch's painting was not produced for church use and apparently was intended to be displayed by his noble patron. In his painting, the left and right panels fold over, and on the back side depict a small God in the upper left-hand corner creating the world as a gray globe with plants but no animals. On the opened inside, the left panel depicts God, in the form of Jesus, presenting Eve to Adam in the Garden of Eden. Carroll refers to this panel as Paradise. The center panel depicts many naked young men and women engaged in multiple activities and enjoying themselves. Though there are some potentially sinister signs, the people seem to be the early descendants of Adam and Eve, and Carroll refers to this panel as Garden. The right panel represents a later stage in which older men and women are shown in a dark environment where people are being tortured by various demonic creatures. Armies are burning buildings, and the world appears to be in chaos. Carroll refers to this panel as Apocalypse.

Bosch's style is not as precise as that of van Eyck, but he is more inventive in his subject matter. There is so much going on in this painting, with most of the activity unclear, that it isn't easy to decipher. Furthermore, Bosch invents physical structures of unique appearance. While, on the whole, the painting does follow the traditional triptych model, it represents an evolution toward secular painting. I think that the gradual increase of nudes in religious paintings represented the preferences of wealthy male patrons when paintings became secular status symbols created for display in their homes.

One of the most striking figures is the "Treeman" in the Apocalypse panel. This is a pale male figure facing toward the front of the painting. His torso resembles a large white egg with a hole in it and people inside, apparently drinking. His legs supporting the torso are tree trunks. Some commentators believe that this could be a self-portrait of Bosch, positioning himself as a witness to the debauched state of the world. I was reminded of van Eyck's Arnolfini Portrait, which was painted in 1434. That portrait appears to be the solemnization of a marriage, and van Eyck may have represented himself as a witness to the marriage by painting a small image of himself in a mirror behind the couple. Bosch may have done the same, but in his case he was witnessing the Apocalypse.

Besides chronicling the gradual decline from innocence to depravity after the Garden of Eden, which fits the standard Christian theological model, Bosch introduces a more human and sociological element that wasn't evident in earlier triptychs. Interestingly, Bruegel the Elder is known to have seen the painting, and clearly Bosch influenced his paintings of peasant scenes. This shift to secular subjects is a common pattern in art history, and I am reminded of Édouard Manet's Olympia, which revolutionized the art world by taking Titian's Venus of Urbino and representing her as an unglamorous prostitute. Manet, like Bosch, was an artistic revolutionary. Because of his invention of bizarre physical objects, Bosch must also be credited for inspiring Salvador Dalí and other surrealists four hundred years later. However, on a less sanguine note, it can be dispiriting to see that some of the chaos of the late Middle Ages and early Renaissance is still with us today.

Diary

I had hoped that by now I would be reading another book, but for various reasons I haven't started. There have been visitors, and my responsibilities have increased slightly, with chauffeuring, plant care and gardening. Besides the usual ten houseplants, five of which were adopted from my inattentive partner, I am taking care of her three other plants and twelve plants that won't fit into my daughter's apartment. That brings the total to twenty-five. The vegetable garden is extremely productive this year, because it has a new layer of gardening soil on top. We can barely keep up with all of the tomatoes at the moment. Because this has been a very sunny, hot and dry summer, a lot of watering has been necessary. On the positive side, the lack of rain has meant less lawn mowing.

William was attacked three or four times over the spring and summer and had bite wounds and a limp until recently. I think that the chickens that attracted the predators are gone, and that may reduce future attacks. I don't know whether predators caught the chickens or whether the chickens were removed by their owners. William doesn't seem to be catching many rodents at the moment, but he is enjoying the cooler temperatures and spends a lot of time outside during the night. He has been in a good mood, and his behavior has changed accordingly.

I am still distracted by the Trump phenomenon and all the MAGA nonsense. In a sane world, people would have recognized Trump's flaws five or six years ago. I agree with Rana Foroohar's recent assessment:

As someone who has spoken to my share of shrinks...I have come to believe that Trump is a paranoid narcissist, full stop. Narcissists are often charismatic, and he certainly has animal spirits. They are also deeply vulnerable about most things, but particularly the big stuff, like power, sex, and money. In that sense, former Vanity Fair editor Graydon Carter was really on to something with the "short-fingered vulgarian" comments.

Narcissists often come from Hobbesian families. It's not about love, it's about winning. If one person is up, another must be down. They don't develop empathy, or guilt. This isn't a reason to feel sorry for them, though you might. It's simply a key fact in understanding how they behave. Narcissistic behaviour has a logic that is all its own. And really toxic narcissists like Trump, particularly those enabled by money and power in such a way that they never stumble and really have to change, don't know how to do better, or even how to want to do better, because that involves empathy. Which they by definition don't have.

That's why I never think about why Trump does anything he does through the lens of economics or even politics. I simply think of him as a paranoid narcissist, and go from there. It's like being a very stable genius. But not.

If it only involved Donald Trump, I wouldn't pay much attention – who would pay much attention to all his failed business ventures? The worry is that, to many, he maintains credibility as a public figure.

I am still spending a fair amount of time on investing, but now am simply trying to stay slightly above the indexes. I am losing money, but am still way up since early 2020. I don't think that we are facing a significant recession or significant inflation. Hopefully, the economic situation will resolve itself within a few months and people will start paying more attention to climate change.

We are beginning to plan for winter. Heating costs are going up, including both heating oil and firewood, and there may be shortages.

Existential Physics: A Scientist's Guide to Life's Biggest Questions

I just finished this new book by Sabine Hossenfelder. It has similarities to her last book, Lost in Math: How Beauty Leads Physics Astray, which focused on how physicists entertain exotic theories that are difficult to link to actual observable events, and how this emphasis on mathematical aesthetics is contributing to a slump in the development of useful new theories. The new book continues the pragmatic emphasis of the last book, but covers a broader range of topics. Although Hossenfelder writes clearly and concisely, the subjects are quite abstruse, so, whether she likes it or not, the content is way over the heads of most readers, though, if they make an effort, they may get the gist of it. Even so, though I think it's much more interesting than A Brief History of Time, Stephen Hawking's bestseller, I don't think it will sell as well. That is probably one of the least-read books on people's bookshelves. From a marketing standpoint, it might have helped if she had ALS and used a speech synthesizer. However, Hossenfelder has already established herself as a credible science pundit, and this book will enhance her career.

Some of the topics interested me more than others, and I'll focus on those. As in the last book, there are interviews, but I didn't find them enlightening. They are entertaining when, for example, she critiques her host's housekeeping and hints that she may dislike men with long hair. Some of the subjects are difficult, and covering them in brief chats doesn't do them justice, though her publisher probably encouraged her to keep it as light as possible. She seems more confident in her interviews than before, when, for example, she was intimidated by Steven Weinberg, but I doubt that she will ever rake an interviewee over the coals. In some ways, she is refreshing, because she doesn't have a gigantic male ego and is simply attempting to educate people.

Chapter 2 is "How Did the Universe Begin? How Will it End?" In this chapter, Hossenfelder concludes that we may never know. To me, some related questions are "How many universes are there?," "Are universes structurally similar?," and "Can the laws of physics in a particular universe change?" I don't think that we will ever know anything about this, except in the sense that we may eventually discover that the laws of physics in this universe are constant. I dislike the psychological impact of these kinds of questions because, if we want to think that our lives are significant, what if there is an infinite number of lives, and an infinite number of those lives are identical to yours? This hardly boosts one's sense of importance. In one universe, your equivalent may have made a slightly different decision, and the consequences may have been significant. I'd rather not think about it.

Chapter 6 is "Has Physics Ruled Out Free Will?" Hossenfelder concludes:

According to the currently established laws of nature, the future is determined by the past, except for the occasional quantum events that we cannot influence. Whether you take that to mean that free will does not exist depends on your definition of free will.

Although I'm hardly qualified on this topic, my feeling is that it is possible that "quantum events" may also be found to fit a yet-to-be-discovered deterministic model. This would mean that everything that has occurred in this universe was predetermined, i.e., free will does not exist.

"Is Consciousness Computable?" is an interview with Roger Penrose. Penrose thinks that consciousness may not fit within a deterministic model. I think that it does. This is one of the areas in which physicists are prone to making mistakes. My feeling is that physicists are not generally competent in biology. I think, for example, that most mammals have a consciousness quite similar to ours. This means that, if consciousness is unique, we're no more unique than chipmunks. One of the main themes throughout human history has been to show how humans are somehow superior to other animals. We're not that different. I think that Roger Penrose has seen better days as a thinker.

Consciousness is also discussed in Chapter 8. There, Hossenfelder makes a good point in a rather amusing way:

We don't yet know exactly how to define consciousness, or exactly which brain functions are necessary for it, but its a property we observe exclusively in physical systems. Because, well, we observe only physical systems. If you think your own thoughts are an exception to this, try thinking without a brain. Good luck.

In some respects, Hossenfelder is more tolerant of ideas that she disagrees with than I am. For example, she doesn't agree with Nick Bostrom's idea that the universe could be computer simulation. I agree with her and would not even have bothered to discuss Bostrom's ideas. Similarly, although she is not religious, she is reluctant to criticize religious people. My view is that religions serve an evolutionary purpose for humans. Historically, we have needed them both to help maintain cohesive groups and to provide a kind of assurance of our place in the universe, given that we are conscious and the answers are beyond our comprehension. I think that Hossenfelder's understanding of evolution is similar to mine, but that, because she is not a biologist, she may not understand all of the implications of being a biological entity. To me, this means that everything about us has come to be for survival reasons. Physicists tend to see mathematics as an objective way to discuss reality, whereas I see it as an evolutionary development that is dependent on biology for its existence.  In my view, mathematics exists only because humans communicate with language, and mathematics is the most precise language that we've developed. I would not have given space to Max Tegmark, who thinks that the universe is a mathematical entity. In the books I've discussed by Frans de Waal and Giorgio Vallortigara, evidence is provided that other animals are conscious and even have rudimentary mathematical skills. My interpretation is that consciousness is nothing special and is simply a byproduct of sophisticated brains. Without evolution, mathematics would not exist.

I should mention an anecdote that I read many years ago. When asked how he came up with an idea, Einstein described how he had an odd sort of physical reaction when it occurred to him. It had nothing to do with mathematics, and sounded to me like an intuitive insight. The process of expressing it mathematically was separate, and sometimes he needed help with that.

One area that Hossenfelder doesn't specifically discuss is morality. For me, it is important to understand that morality is also a product of evolution. I have been writing about this for several years now and am amazed that no one else seems to have this opinion. A lot of time could be saved by ignoring philosophical treatises on morality, free will and consciousness. Contemporary physics pundits can get into ruts if they indulge their philosophy colleagues too much.

Towards the end of the book, there is a discussion of AGI, and Hossenfelder's views are similar to mine. I think the main danger is that it will fall into the wrong hands, not that it will inherently be a menace to us.

On the whole, I found reading this book to be an interesting and challenging exercise. However, if you're like me, you may not have anyone to discuss it with. Most people never think about these topics, and they can be quite scary.

Diary

Since I don't do "light summer reading," I am reading almost nothing at the moment and am beginning to accumulate some books for potential winter reading. I have become somewhat interested in the ideas of Martin Rees in recent years, and I just listened to this interview conducted by Lex Fridman. The impression I got is that Rees is approaching death, and that he is trying to inspire young scientists in their future work. On the whole, I thought that Fridman did an acceptable job, but there were instances during which he displayed extreme naïveté. I don't think that he was the right person to extract some of Rees's better thoughts, so it seemed that the discussion got a little off track at times.

I think that astronomy is the best field for understanding human existence in the context of the universe. Because Rees is less of an egomaniac than many other public intellectuals, he tends to provide more nuanced answers and doesn't waste time on professional self-aggrandizement. For example, he recognizes that physics is much easier than biology, while physics itself is increasingly becoming less intelligible. For this reason, he is one of the first scientists I've heard who supports the use of AI in future research, because it is already evident that intractable human cognitive limitations place an upper limit on what we can understand. In this vein, I noticed recently that serotonin has been found to have less influence on depression than was previously thought, indicating that Robert Sapolsky and many other biological researchers have been getting it wrong. Many of the widely-accepted ideas of today will be refuted in the future.

The overall view that I've developed over the years is that humans are essentially sociable primates, i.e., we have evolved to cooperate more than any other primate species, while also possessing the capacity to communicate through language, and have thereby become more evolutionarily successful, mainly in the sense of having the largest population of any primate. While this situation has been beneficial in relation to other species, as time passes, the population grows and the environment deteriorates, some of the advantages of cooperative behavior have become less relevant. For example, with the increasing complexity of daily life, we unconsciously tend to attribute greater competency to political leaders, academics and intellectuals in general than they actually possess. To understand this, one need only follow the news. Because politicians have little control over short-term economic conditions, when voters blame them for poor conditions they pretend that they can fix everything. In other words, the proper actions are not necessarily taken, and the public maintains a poor understanding of economics. In the U.S., the idea that voters ever have to make sacrifices has been eradicated: when conditions become bad, they can just vote for a politician who requires nothing of them.  It's actually worse than this, because economists themselves don't necessarily understand the economic problems either. Since there is no recent precedent for a pandemic followed by inflation, most economists are winging it: this brings to light the fact that their models are never completely accurate. The lessons learned since the Great Depression may be insufficient to ward off future economic downturns.

What I am finding is that even highly-educated, scientifically-minded people often hold unfounded ideas based largely on their social backgrounds. Thus, as Rees notes in the interview, some tech entrepreneurs are following a path in which they will gradually become immortal and perhaps explore the universe at their leisure. My view is that we have not evolved to become immortal, and that we wouldn't necessarily like it if we were. I have been retired for fifteen years, which I think is an adequate amount of time to relax and pursue various interests. I don't have the slightest idea what I'd do if I were alive for another million years. In order to do so, I would have to evolve in directions which are completely unfamiliar to me, to such an extent that I wouldn't be recognizably human. In all probability, I would just be an expensive robot, and robots don't necessarily care whether or not they are alive. Conceptually, I think the key is whether you want to be a biological object or a non-biological object. To me, being non-biological would be about as exciting as becoming a clock. Our evolutionary past has prepared us to devote our resources to survival, not to understanding the universe. In any case, there is probably an upper limit on how well the universe can be understood by any being. What do you do when you reach that limit?

On a more mundane level, the issue can be seen as whether we really want to expunge the irrational animal impulses that are built into our brains, as discussed by Vinod Goel in Reason and Less. On the surface, that might be appealing to some people, and the world might indeed be a better place if it were governed more rationally. But my current thinking is that the transition to evolutionarily post-human life would require a kind of death that I would find unappealing. That is why I prefer an AI-controlled environment for the benefit of mankind to an immediate transition to post-human life. Strictly speaking, this is a subject that could in theory be studied. It is possible that species on other planets have actually made a transition to a post-human equivalent, and it may someday be feasible to study them. On the other hand, if post-human-equivalent extraterrestrials are never found, that fact itself may be indicative of something.

Thoughts on Autism

Since starting this blog, I've been avoiding discussing close relatives and my current relationship. However, I have mentioned psychiatric disorders on several occasions, primarily in the context of people in the biographies that I've read. For example, Ludwig Wittgenstein was almost certainly autistic. I thought I'd make separate comments about autism, because, from my point of view, it is an emerging topic. During the 1940's, early studies concentrated on severely impaired autistic children, and it was not until the 1990's that high-functioning autistic children came under study. Since then, in the early 2000's, high-functioning autistic adults were studied, and now the topic is broadly discussed under autism spectrum disorder, which covers all ages and a wide variety of symptoms. The main symptom is social impairment, but there are many other symptoms, such as repetitive behavior, sensitivity to loud noises, learning disabilities and special intellectual talents. The same symptoms are not necessarily present in all autistic people. It appears that autism runs in families, but that aspect does not seem to have been studied much so far.

For the record, I don't think that I'm autistic. In my family background, I had an uncle who could have been autistic, but I have no way of finding out now. As a child, he became fascinated with watches, and as an adult he became an engineer and designed and made a clock that was used on one of the NASA missions to Mars. I hardly knew him, but one of his daughters thought that he could have been autistic. I think that he may only have been an introvert, and I've noticed myself that introversion can be confused with autism, though the two are neurologically unrelated. To an undiscerning observer, it may not be apparent that an introverted person prefers to be alone, whereas autistic people may prefer to socialize but lack the skills necessary for social acceptance. There is also a certain amount of confusion about autism and intelligence. Nerdy students probably have a good chance of being autistic, but many autistic people are poor students. I've noticed that autistic people tend to socialize with each other, since it is difficult for them to develop friendships with those who are more socially adept, but they may still have different intellectual abilities within their group. Because I am intelligent and introverted, some people may have thought that I'm autistic, but I'm not.

It is relevant to me to know something about autism, because I've spent about fifty years, some of which were hardly harmonious, among autistic people. My ex-wife is probably autistic, and so is my son. My current partner is autistic, and so are some of her relatives. Her immediate family is very high-functioning. Her ex-husband graduated from Yale and Yale Law School. She graduated from Cambridge and the University of Chicago Law School. One son also attended Yale and is a software engineer. Another son has a Ph.D. in mathematics and also works in the tech industry. The two children make so much money that they probably could retire in their early forties.

As I mentioned in an earlier post, I have been intrigued about my ex-wife's family with respect to heritable mental illness. No one ever talks about this kind of thing, so, in the course of my genealogical research, I investigated her family background. On her father's side there was no sign of mental illness. However, both her mother and an aunt exhibited psychiatric symptoms. I found that her mother's grandmother had attempted suicide at 19, became pregnant at 20, before marriage, and proceeded to have four children. Her husband was a petty criminal who died in prison at the age of 45. She was born in 1875 and disappeared in about 1909, abandoning her four children. I think that she was probably the source of later mental illness in the family, though it is also possible that her husband contributed. Looking at four generations of her descendants, a variety of autistic symptoms have occurred right up to the present. My view of my ex-wife is that she is an average-functioning autistic person who may not know that she is autistic but has always been socially inept. High-functioning autistic people can be more interesting, but the same social impairment is still apparent.

On a more general level, I have been thinking about how the human brain works and how its resources are limited. Having good social skills demands far more brainpower than you might expect, so the brain makes tradeoffs. In a stable social setting, such as a homogeneous upper-middle-class environment, the social stability may obviate the need for social skills somewhat and leave room for the development of intellectual skills that are associated with greater social prestige, better career prospects, or both. This could explain some of the success of some high-achieving autistic people. In general, the rise of the tech industry has facilitated this process. It is possible that the genes for high-achieving autistic people have always been there, but the opportunity for their expression may have been more limited in the past.

I think that the Internet and digital technology have made the environment much more autism-friendly than it was a few decades ago. However, this isn't necessarily an entirely positive development. First of all, there is no advantage for low-functioning autistic people, and, more importantly, the high-functioning autistic people like Bill Gates and Elon Musk may be exceptionally talented in some areas, permitting them to make billions of dollars, while their social ineptitude probably makes it challenging for them to foster a cohesive society. For example, Bill Gates is never going to make a moving speech. Although there may be other causes, it is probably not a coincidence that social cohesion began to erode with the rise of the tech giants. Of course, some of the tech people don't seem particularly autistic, but I think that the net effect of the new technology has been to make the environment more autism-friendly than it was in the past. One area of recent social change that could be autism-related is the rise of political correctness. Autistic people, particularly the high-functioning ones, like rules, and they are often insensitive to social subtleties. Thus, robotic people seem to be becoming the norm, and, for better or for worse, we may be witnessing the death of humor.

Diary

I've been watching with some interest the news coverage of the shooting in Highland Park, since I used to live there not far from the parade route (though I never went). But for the most part it's just another routine shooting: a confused young male copycat event that is becoming a frequent occurrence. The Select Committee to Investigate the January 6th Attack on the United States Capitol has been more interesting. I like it not because it is producing evidence of a crime, but because it shows how Trump was enabled by unprincipled staff members who covered for him while he was in office and are reluctant to speak publicly about it even now. It has been obvious for several years that Trump has the mentality of an opportunistic criminal, and that his election in 2016 was probably the greatest mistake in American political history. I find it amazing that to this day only two prominent Republicans, Liz Cheney and Adam Kinzinger, have spoken out against him. Although the political system in the U.K. isn't functioning well either, at least Boris Johnson's cabinet resignations are forcing him out. In addition to these events, we have the recent rulings of the United States Supreme Court, which now contains a majority of religious fanatics. It's difficult to imagine that they all attended college, given some of their ideas.

To my readers who are tired of hearing my opinions about stupidity, I can only say that stupidity is the greatest underlying problem of this era. As I've been saying, the press holds some responsibility for this, because, unless an explicit crime such as a murder occurs, they tend to be idea-neutral in a misguided attempt to behave impartially. If they had ferreted out more information about Donald Trump before the 2016 election and actively publicized it, it may have been easier for Hillary Clinton to make a better case for herself as the most competent candidate. While Trump himself may not be directly responsible for all of the chaos that arose during and after his presidency, he is at least partially responsible for the rise of right-wing extremism and has ruined the Supreme Court by appointing three conservative justices. If Ruth Bader Ginsburg had retired under Obama and Merrick Garland had been rightfully installed, the Supreme Court would not have ruled against abortion and the EPA would still have the authority to protect the environment. These errors could be corrected over the next few years, or conditions could worsen if they are followed by new ones. Because the U.S. Constitution doesn't work and Congress and the Supreme Court aren't doing anything about it, dire outcomes are possible. Biden isn't much help either, and someone else could do a better job than he has. I don't think that Kamala Harris is ready for prime time.

From my point of view, although I believe that there is strength in numbers, a partial breakup of the U.S. might possibly be an improvement. After all, Texas and Vermont were once separate republics, and the consequences were not disastrous. It isn't hard to imagine at least three republics now: West Coast, Northeast, and everything else. Perhaps the Upper Midwest could also form a republic. While I generally prefer fewer countries and governments, some conflicts could be resolved by separating regions based on intractable ideological differences. Vermont probably couldn't survive alone as a nation-state, but Vermont + New York + Connecticut + Massachusetts + New Hampshire + Maine probably could. So could California + Oregon + Washington. If Texas + Oklahoma + Arkansas + Louisiana + Tennessee + Mississippi + Alabama became a country, I wouldn't care – or visit it. There would probably be a few straggler states, but a solution to that could be reached. Under a scenario like this, the West Coast and the Northeast might have the healthiest economies and the strongest alliances with the European Union. Many parts of the U.S. would probably prefer alliances with Russia and Saudi Arabia.

In other respects, I'm having a ho-hum summer. William has again been attacked by something and was bitten. He has had a minor limp since May, and when he went in for his annual shots on June 27 he had a temperature, for which the vet gave him antibiotics. He seems to have recovered, but the limp is still slightly visible. Recently, our neighbors started to raise chickens. I think that chickens attract predators, such as coyotes, bobcats, foxes and fishers, and, to a lesser extent, bears. Unless the predators succeed with the chickens, they probably won't stick around. I'm setting up my 18" Dobsonian telescope tonight, since it should be clear and somewhat dark for two days in a row.

Popular Nonfiction May Distract from Better Ideas

Recently, I temporarily switched from reading accessible nonfiction books that are popular among educated readers to newly-published books issued by academic presses. One was from Cambridge and two were from M.I.T. As a matter of curiosity, I've been following their reception to see what kind of reactions they've evoked. Understandably, Paleolithic Europe, by Jennifer C. French, isn't attracting much attention, because it costs a lot and is specifically intended for an academic audience. However, I am surprised by the tepid response to Born Knowing, by Giorgio Vallortigara, and Reason and Less, by Vinod Goel, because they are not directed exclusively toward academic readers, aren't as expensive and include important findings in scientific research that I think have significant applications in the field of human cognition, not on a purely theoretical basis, but regarding the workings of cognitive functions that are evident in everyone's daily life. Of course, this kind of reaction is to be expected and corresponds with what I've said about the publishing industry. You won't necessarily make much money from good ideas, but you can usually make a lot of money by carefully promoting mediocre or bad ones simply by using existing commercial channels.

Born Knowing, I think, is relevant to a wide range of disciplines. At the most basic level, it shows how the neurological systems of all animals, both simple and complex, are the product of evolution, and, as such, are related primarily to survival and reproductive success and do not necessarily mirror what we might think of as objective reality. Our neurological systems mediate between us and the world. Although Vallortigara does not focus on human cognition, I think that he goes a long way toward refuting some of the ideas that are still popular among some philosophers. He seems inadvertently to be reviving Kant's concept of phenomena and noumena. In particular, I think that his findings can be construed as a refutation of Plato's Theory of Forms, and, more generally, of the objectivity of mathematics. In a way, he dovetails with Kurt Gödel's incompleteness theorem, and I think that this has enormous implications for what we think counts as objective knowledge. The book also makes clear that language is not necessary for rudimentary thinking, specifically in arithmetic and geometry. I would go a step further than Vallortigara and say that the reason why mathematics currently seems inadequate for solving the fundamental problems of physics could be that mathematics is an aspect of our neurological makeup and not something fundamental to nature. Organisms like us did not evolve to perform such tasks, and our neurological features may limit our capacities in that respect.

Reason and Less, for me, is valuable in a less theoretical sense, because it discusses our actual brain function. As I said in my comments about it, it provides a practical basis for critiquing public decision-making processes so as to minimize cognitive errors. I found Goel's model more useful than Daniel Kahneman's, as presented in Thinking, Fast and Slow. Goel shows how irrationality is intractably linked to rationality in the structure of the human brain, whereas Kahneman mistakenly, I think, suggests that, with the proper rewards and coaching, poor decisions can be minimized. Kahneman does not seem to recognize how cognitive dysfunction is endemic to humans, and that there is no such thing as a quick fix for this problem. In my view, Goel's model is more appropriate than Kahneman's at the policy level, because it takes into account the fact that the policymakers themselves are subject to the same kinds of errors as the people whom they are attempting to assist.

The point of this post, then, is that important findings such as those published by Vallortigara and Goel can easily become buried in the media and never get the attention that they deserve. At the same time, less significant ideas such as those put forward by Daniel Kahneman and pundits like Steven Pinker get all of the attention. Of course, there is always the chance that, over time, the better ideas of obscure academics will be promoted in academia and make their way to public consciousness. However, as the publishing system currently works, this can hardly be considered an efficient process. Thinking, Fast and Slow became a bestseller and made Kahneman a household name, while no one has heard of Vinod Goel. Similarly, Steven Pinker is one of the best-known public intellectuals in the world, while Giorgio Vallortigara remains an obscure researcher. Unsurprisingly, Kahneman published with Farrar, Straus and Giroux, and Pinker with Penguin. These publishers have far larger production runs than the academic presses, and their purpose is to make money, not to promote good ideas. I suppose that this is just the way that the world works and is to be expected, but I still find it annoying that there are people out there who have good ideas which never make it into public consciousness, while lesser works dominate the media year after year. It is important to keep in mind that, at any given time, the ideas promoted by leading public intellectuals may be inferior to ones that are already circulating in smaller circles.

A Confession

My Lord, I loved strawberry jam
And the dark sweetness of a woman's body.
Also well-chilled vodka, herring in olive oil,
Scents, of cinnamon, of cloves.
So what kind of prophet am I? Why should the spirit
Have visited such a man? Many others
Were justly called, and trustworthy.
Who would have trusted me? For they saw
How I empty glasses, throw myself on food,
And glance greedily at the waitress's neck.
Flawed and aware of it. Desiring greatness,
Able to recognize greatness wherever it is,
And yet not quite, only in part, clairvoyant,
I knew what was left for smaller men like me:
A feast of brief hopes, a rally of the proud,
A tournament of hunchbacks, literature.

Paleolithic Europe: A Demographic and Social Prehistory

I've finished reading this new book by Jennifer C. French, an archaeologist, and will sum up my reactions. The text is academic in style, and most of the book is a recapitulation and discussion of research papers on the topic. It is an effort to describe ancestral trends and living conditions in Europe from about two million years ago to about 15,000 years ago, and a paucity of relevant data results in a murky picture until the more recent period. The species described are hominins, i.e. modern humans and extinct human species, but not other primates. The research is conducted through three primary sources: stones, bones and genes. The stones are rock artifacts, usually tools or weapons, and, more recently, figurines such as the Willendorf Venus. The bones are bones and teeth from archaeological digs, and genes, when available, contain genetic information. There is also some use of research on modern hunter-gatherers, though that is an unreliable model, since most of them have had some contact with culturally modern humans. The chart below sums up the main research findings:


The earliest known Europeans were H. antecessor and H. heidelbergensis. They may have moved in and out of Europe intermittently, starting in Africa. H. neanderthalensis is the only Homo species thought to have originated outside Africa and mated with both the Denisovans, who lived in western Asia, and H. sapiens in Europe and elsewhere. Most of the early humans who migrated from Africa traveled to Asia and never went to Europe. Some returned to Africa and reemerged later.

Until H. sapiens arrived, the human population in Europe was quite small.  H. neanderthalensis was subject to food shortages and infertility. Because they had bulky bodies, they required more food than modern humans. They appear to have been less mobile than us, and their extinction may have been related to inadequate food supplies. In the skeletal remains there are signs of violence at an early age, and there is more evidence of cannibalism than in H. sapiens, though the context for that cannibalism isn't known. The genes of H. neanderthalensis indicate periods of inbreeding. H. sapiens behaved somewhat differently from H. neanderthalensis and appears to have been both more social and more mobile. That allowed them to maintain large networks that were beneficial during hard times, and their population increased. French focuses somewhat on nutrition, disease and fertility to explain population fluctuations. She seems reluctant to say that H. sapiens may have had a significant survival advantage because of increased eusocial behavior compared to earlier species, but, to my way of thinking, that would be the best single explanation of how they survived and flourished during a period of wide climate fluctuations in the Ice Age.

Overall, I found this book interesting and informative, but I disliked the academic writing style. Also, the feeling that I got was that the events discussed were so far in the past as to render them inaccessible for all practical purposes. We may never have a clear picture of what human culture was like in Europe 35,000 years ago, so the attempt to study it may be futile. For me, this book is a reminder of how little we know and of how little we may ever know. I should also note that others may not want to read the book, if only because it is an expensive college textbook, and you will probably never see it in a local bookstore or library. The Kindle edition currently costs $80.

Diary

I am in my usual spring mode and haven't had anything to say that is suitable for public discussion. As always, the weather is fantastic at this time of year, and the lilacs have been blooming. The large pink ones are starting to fade. We also have an old white one, which was probably planted in the nineteenth century, blooming now. My favorite, the one with small pink flowers, is about to bloom. The grass has been growing wildly, the tomatoes are planted, and the yard looks shockingly different from a few weeks ago. There was a heavy rain recently, and the cumulative seals that I've made to the basement foundation held up well, with very little leakage. The foundation in the original part of the house is made of stones – not exactly waterproof – and when we bought the house in August, 2011 there had been a recent flooding. I think that Enos Severance may have picked this location because of the sandy soil, which drains well. His father's house nearby is standing in clay and more prone to sitting water in the basement. The basements were probably used for food storage in the 18th century, and were best kept dry.

From a social standpoint, COVID-19 is still curtailing activities here. Vermont still has an overall infection rate that is relatively low for the country, but it is now behind Virginia, Washington, Maine, Hawaii, Oregon and Maryland. Mask fatigue is causing reduced mask-wearing, and, for the first time, someone we know here became infected. Fortunately, it was a very mild infection. There has also been a rise in infections at the college. Overall, Addison County has a 1 in 6 infection rate, which isn't good, but is still better than most of the country.

As in other years, the conditions for stargazing haven't been very favorable. The best times are usually brief moments during the middle of the night and are difficult to catch. It doesn't help that I'm the only astronomy enthusiast in the house. Even so, I would like to set up my 18" Dobsonian telescope again this year – I haven't since 2020. I like reminding myself that other parts of the universe aren't like earth. In the July, 2022 issue of Sky and Telescope there is an article by David Grinspoon saying:

I do think that humanity has a chance to live long and prosper, to seed a truly sustainable society that could eventually sprout throughout the galaxy. But right now, any ETs exploring our solar system, seeking new prospects for their galactic club of wise civilizations, would probably take a quick scan of Earth and keep on searching.

In other words, there is no sign of intelligent life on earth.

I've started to read a new book on paleolithic Europe, a subject that interests me. However, it is written in an extremely academic style that Richard Feynman would find unintelligible. I think that the introductory discussion of research methodology is a bit excessive, but it is probably acceptable given that the book will be used for upper-level courses in archaeology. This is an extremely challenging subject from a research standpoint, since the author focuses on demography and social prehistory dating backward from 15,000 years ago. Obviously, the Enlightenment thinkers had no idea what they were talking about when they discussed early humans, and this book will be a significant improvement. If I ever finish it, I'll comment on it.

William is enjoying the warmer weather. As far as I know, he hasn't caught much recently. The other day I rescued a hummingbird that he was carrying around in his mouth, and it flew away. A few weeks ago he was in a serious fight and had large bite marks on his front right leg. He was limping for a few days, but seems to have recovered.

The End of Astronauts: Why Robots Are the Future of Exploration

This is a new book by two astronomers, Donald Goldsmith and Martin Rees, in which the past and future of the exploration of the solar system and beyond is discussed in some detail. As the title suggests, the continued suitability of astronauts for this purpose is a running question throughout the book. Chapters cover projects involving near-earth orbits, the moon, Mars, asteroids, space colonization, the costs of space exploration and space law. No firm conclusions are reached, and the two simply finish by saying that the exploration of Mars is about to become the focus of many groups.

The greatest single obstacle to hands-on space exploration is gravity, because a lot of energy is required to leave the earth's atmosphere. Furthermore, manned space flights are far more expensive than unmanned flights, because the systems necessary to support human life are much heavier than the systems necessary to support robots. Although there have been situations in which a human presence on a space mission has been more efficient than a robotic presence, advances in AI are rapidly closing the gap. One of the disadvantages of human astronauts is their susceptibility to cancer caused by various forms of radiation, which consequently requires heavy shielding on manned flights. Other human requirements in space also increase weight in comparison to robots.

Because of the problem of the earth's gravity, the exploration of other planets and asteroids would be less costly and easier if the missions originated on the moon or other objects with weak gravity. For this reason, there will probably be permanent bases on the moon relatively soon. The far side of the moon would also be an excellent location for telescopes. The authors don't draw distinctions between missions based on scientific advancement, popular enthusiasm, billionaire hubris, commercial interests or geopolitics, so there is no clear perspective defining which activities are appropriate – I found this a little disappointing. They are simply predicting what is likely to happen next. So, in a few years there will be bases on the moon, and in about forty years there may be bases on Mars, the moons of other planets or asteroids. Among the motivators are international competition, the mining of rare elements, curiosity about whether life exists elsewhere in the solar system and the potential development of space habitats for humans. The moon contains helium-3, which could be used to generate energy. The moon, other moons, Mars and some asteroids contain water, which could be useful if bases or colonies are developed. Besides the possibility of human colonies on Mars, some people envision colonies in large, rotating cylinders in space or on the moons of other planets. The authors dutifully mention the hostility of non-earth environments to humans. 

On the whole, I found the book informative about a topic that is likely to become far more important in the future. However, the focus on technical facts omits many of the significant problems associated with non-earth habitation by humans. If the authors had consulted biologists and sociologists, they might have provided a fuller picture of the hazards of space for humans. To me, they have overlooked the fact that, as earth-evolved organisms, humans are unlikely to feel at home anywhere other than on earth or an extremely close simulation of it. I think that living in a Martian colony would probably be like living in a small, remote motel somewhere in Nevada, without the possibility of opening a window or going outside unless protected by a special suit. The authors discuss the terraforming of Mars, i.e., the conversion of Mars to an earth-like habitat. Although that could conceivably occur in the distant future, there is no guarantee that people would be happier there than they are here. Moreover, if humans were to leave earth because it became too crowded, polluted, hot or violent, why would anyone expect that space colonies wouldn't also become too crowded, polluted, hot or violent? If the colonists were trying to escape poor governance on earth, why would they think that they would find better governance in a space colony? I think that, with all the expense and risk associated with human travel to and residence in space, an analysis of what it would take to make living on earth more desirable and sustainable ought to have been made. We have the ability to painlessly reduce the population here by limiting the number of births, and we have the technology to solve the problems of climate change. In particular, it would be far easier to terraform earth, returning it to an earlier state, than Mars or anywhere else, and in this respect the book is extremely shortsighted. In a similar vein, the authors are neutral on speciation. It is true that speciation occurs on its own, as species adapt to changes in their environments, but, speaking for myself, I am perfectly happy being a human. As far as I'm concerned, Elon Musk and his friends can all become cyborgs and move to Mars. Good riddance!

Diary

I'm behind on my posts because I haven't had much to say. The arrival of spring always prompts changes in my daily activities. I spend less time reading, less time on the Internet, more time preparing for gardening and more time outdoors. I have also been attempting to help my daughter buy a house, which is a nerve-wracking experience at the moment. All of the decent houses in good school districts that come on the market near Lebanon, New Hampshire are sold almost immediately at prices above the asking price. Buyers have no way of knowing whether they have bid high enough, and the houses are overpriced to begin with, usually $100,000 to $200,000 more than they would have cost three years ago. Higher interest rates are starting to reduce demand a little, and one can only hope that the market will stabilize within a few months. In the meantime, my daughter's situation isn't bad. They have a nice apartment, my grandson is being homeschooled, and it takes my son-in-law three minutes to get to work. They also have access to the Dartmouth library for reading material.

As you might expect, I am following the war in Ukraine, which is also a source of unease. After Donald Trump, I'm a little desensitized to idiotic political leaders, but Vladimir Putin is far worse. Like Trump, he is completely out of his depth as a leader, but he is emboldened because he has little fear of being removed. In an ideal world, he would be arrested and charged with war crimes, but that seems unlikely. He might also be assassinated, but he is prepared for that too. All of his propaganda will collapse eventually, because, with the Internet and news coverage, the rest of the world can see in real time what is going on. The Russian-speaking inhabitants of the Donbas have no particular loyalty to Russia, and Putin's arguments are pure fantasy. One Putin expert says that Putin is waging this war only to increase his popularity in Russia, a strategy that has worked for him in the past. He is actually ruining the country by damaging its economy and accelerating the brain drain that has been going on there for decades. It doesn't help that he is using a dated Soviet-style propaganda campaign similar to the one that ended with the collapse of the Soviet Union. I always wish that people like Donald Trump or Vladimir Putin would be forced to participate in an interview in which they were required to answer difficult, fact-based questions. Neither of them has ever done that, as far as I know. Though I don't think that Trump is as dangerous as Putin, they have a similar modus operandi in that they remain in power by making a deliberate attempt to appeal, with disingenuous theatrics, to the most ignorant and suggestible inhabitants of their countries. Both Trump and Putin know that their supporters are morons. They both have a peasant-like persona that works in either democracies or autocracies. Putin is worse than Trump because he has no qualms about killing people who get in his way; Trump pretends to emulate mobsters, but I don't think that he has ever ordered a killing. The widespread idealization of democracy in the West fails to take into account the weaknesses of human nature. Frankly, the political models dating from the eighteenth and nineteenth centuries are completely obsolete.

Well, I won't bore you with geopolitics. I have a couple of decent books on hand and will read them one of these days.

Diary

I had hoped to start another book by now, but the one I ordered is new and isn't currently available. I am still thinking about Vinod Goel's concept of tethered rationality and find that it could be quite useful. As I've been saying, all of the current major problems in the world are man-made, and it is easy to imagine rectifying them to some extent by taking decisions away from incompetent political leaders and transferring them to new, unbiased science-based evaluation systems. While major political errors seem commonplace these days, Vladimir Putin seems to be topping them all with his barbaric invasion of Ukraine. Whatever Putin thinks he is doing, he is acting not only against the interests of Ukraine, but against the interests of Russia. To be blunt, what Putin needs is counseling: going into this, he could not have accurately foreseen the long-term consequences. He is just a war criminal, not unlike Adolph Hitler, and will be reviled worldwide forever. In my view, the solution to this type of problem is to remove the decision-making role from incompetent dictators like Putin and, in democracies, from incompetent voters who elect incompetent presidents, senators and representatives. Where Goel's model could be helpful is in its drawing attention to the fact that rational behavior is linked to irrational behavior within all human brains. This means that it would be in the interest of humanity to develop impartial systems to evaluate important decisions before they are implemented. At some point, AI will be better at this than humans. I still find it remarkable that Donald Trump ran for office with purely selfish motives and never had any interest in fulfilling the requirements of the job or in understanding any of the issues at hand. Similarly, I think that if you took a deep dive into Vladimir Putin's psyche, you would find that it is full of hubris, misunderstanding and stupidity. Just by using basic aspects of Goel's theory, it would be readily apparent that Putin is stuck in an obsolete Cold War model, because that is what he grew up with.

I am still concerned about Xi Jinping and his implicit support of Putin. If he thinks that he is going to create a sustainable alliance between China and Russia, surely he is mistaken. Putin is no more to be trusted than Donald Trump, and Russia has a historical enmity toward China. It is still possible that Xi will emerge as a peacemaker and scold naughty Vladimir. Besides being the right decision, that would leave China on firmer footing globally.

In the absence of a book to read, I still have Scientific American, Sky and Telescope, the Times Literary Supplement and Consumer Reports magazine. The TLS has a negative review of Michel Houellebecq's latest novel, which sounds pretty bad, and I won't read it. Houellebecq is increasingly coming out as a clueless right-wing sympathizer. I also look at 3 Quarks Daily about once a week. I am tired of their philosophy emphasis, but they still have good arts and sciences content. I'm not as enthusiastic about Sean Carroll as I used to be, because, though he is a good physicist, he has some philosophical leanings. I now prefer Sabine Hossenfelder's videos, because I like the way she thinks. She gets right to the point and specifically dislikes philosophy. I will probably read her next book. As I've been saying, I think that philosophy usually does nothing more than add layers of obfuscation to whatever subject it touches. Thus, sophistry, named after the Greek Sophists, now means:

Specious or oversubtle reasoning, the use of intentionally deceptive arguments; casuistry; the use or practice of specious reasoning as an art or dialectic exercise.

In my opinion, many of the problems of philosophy are being solved by zoologists, neuroscientists and cosmologists. Today's philosophers are trying to remain relevant, but I think they're fighting a losing battle.

The number of daily views of this blog is still somewhat higher than it used to be. As an example of how Internet users waste their time on silly activities, I am getting redirect hits from quora.com. There is a discussion there about whether Bertrand Russell slept with his daughter-in-law, Susan. This is hardly an important question. From the evidence described by Ray Monk, it is possible but probably unlikely. They did have tête-à-têtes, but she had so many sex partners that even Russell was put off by her, and he helped his son divorce her.

In other news, I am no longer needed for taking unwanted books from the library to the transfer station, since they've found someone who will attempt to reuse them. Also, I have placed a "We Stand With Ukraine" banner by the road. I usually don't care much about world or national politics, but what is happening in Ukraine now – in full witness to everyone – is atrocious and unacceptable by any measure.

Reason and Less: Pursuing Food, Sex, and Politics IV

I've finished the book and overall find it to be quite good. I'll just sum up my reaction to the last few chapters.

One of the chapters is titled "When Failures of Belief Revision Are Less than Motivated Reasoning or Sloppy Reasoning." Goel writes:

In short, what I'm suggesting is that some false beliefs are resistant to rational evidence because the motivating desire is not a cognitive desire. It is a desire propped up by instinctual (and other) low-level subcortical systems....

This is one of the most important ideas in the book and is a good starting point for examining the current political polarization within many Western countries.

The next chapter, "Global Belief Revision is Constrained by Neural Maturation," describes how neural systems start out relatively fluid, but once they mature they become less flexible:

If the receptive window of opportunity is missed, no amount of sensory stimulation is going to change the organization of the mature visual or auditory cortex. Once this window passes, the organization of the primary cortex and associated subcortical structures is largely fixed. They cannot be reorganized or repurposed to deal with a radically different environment....These subconscious perceptual biases – even though they may be an accidental feature of the environment – will feed into the In-Group/Out-Group system and infiltrate up into presuppositions and belief systems.

The consequence is this:

If it is indeed the case that the scope for belief revision is limited after neural maturation of the association cortex, it has interesting implications for our standard cognitive and social science Platonic models of mind, where rationality is divorced from biology. Even if in some ideal world the machinery of reason may allow for extensive and perpetual belief revision, the actual biology that supports the machinery may not.

So, in addition to interplay between the different components of a mature brain, neural maturation separately limits change as people age. Goel notes that, according to a survey, young people are generally more receptive to the idea of anthropogenic climate change than older people. This may be because the older people grew up before global warming was a recognized phenomenon, and for this reason their brains do not recognize it as a significant risk.

Goel also includes an interesting personal anecdote that serves as an example. He was born to Indian parents in India. The family moved to Canada when he was young, and he grew up there. Later, when his family returned to India to visit relatives, he found that Indians all looked the same to him, and he could hardly distinguish them. I find this highly amusing, because, in politically correct circles, Goel would typically be described as a racist because of his visual insensitivity to Indians – in this case his own relatives. Obviously, this kind of political correctness is based entirely on biological ignorance. I could relate to this example, because I moved from the U.K. to the U.S. when I was seven and think that it affected my mental development. Since then, I have lived in eight different states, and I always notice that people who have lived only in one location, particularly if it is rural, tend to have very limited worldviews. Education may make a difference, but you can see how the environment affects brain development.

In the final chapter, Goel points out that his tethering model is different from the standard social science and cognitive model, which emphasizes rationality, and the standard evolutionary psychology modularity model, which emphasizes biology and evolution and minimizes the role of reason. I am inclined to agree with his model, because the role of reason is vastly exaggerated in economics and other social sciences, and this significantly reduces its usefulness for public policy. I am sympathetic with the biological/evolutionary approach, but agree with Goel in the sense that some room must be left for reason and its acceptance as a real phenomenon. What I like about Goel's model is that it allows one to speak intelligently about the mountains of cognitive errors that one confronts on a daily basis. As I've been saying, when trapped between right-wing ideology and political correctness, it is disturbing that no one before now has stepped up to address the intense cognitive dissonance that it can cause. This book is the first one that I've read that provides a usable model for that task. It is probably no coincidence that the book was written by a Canadian, who may be less worried about being fired for his views than his cowering American counterparts.

My only criticism of the book is that the subtitle is a little misleading. The main example about food concerns Goel's admission that he is unable to stop eating chocolate cake even though he knows that it makes him overweight and unhealthy. The main example about sex concerns John Edwards, the politician who had an affair while he was running for the Democratic presidential nomination and his wife was dying from cancer. Goel thinks that Edwards was stupid to have an affair at that time. The examples from politics include the first impeachment trial of Donald Trump and the fishing crisis in the Canadian Maritime provinces. Although I found the examples useful, I initially thought from the subtitle that food, sex and politics would be the central themes of the book, but, as it turned out, they were merely a few examples used to explain his theory. One could write volumes on the subtitle alone, and it is probably just as well that Goel remained focused on his model. Perhaps Goel or his publisher thought that "Sex" on the front cover would increase sales. I don't think it has so far.

Reason and Less: Pursuing Food, Sex, and Politics III

This is not a particularly long book, but I am reading it in short segments because it is written primarily for academics, and I've never taken a psychology or anatomy class (behaviorism was popular when I was in college and sounded incredibly boring). Goel's theory is fairly straightforward, and I have no significant objections to his argument, but he is going through all the paces to present his colleagues with a falsifiable theory and is dutifully recounting years of experimental results. He has described in detail the evolution and workings of the human brain and compared it to the brains of other species. Then he says:

Taking this neuroanatomy seriously has far-reaching consequences for our understanding of human behavior. It provides an underlying biological basis for the qualitative differences in autonomic, instinctive, associative, and reasoning behaviors. The biology suggests that the cognitive characterization of rationality as unhindered by more earthly concerns is not rooted in reality. The neuroanatomy paints a picture of hierarchically organized systems but with a clear tethering of newer systems to older ones. 

In the next chapter he makes a case for "feeling" as the mechanism that modulates between the chronologically separated components of human brain anatomy. I am doubtful that this approach will have much influence on his colleagues, but think that it is quite adequate for my purposes. Whether or not he can provide an academically acceptable model for human behavior, I think that it is sufficient as an intuitive model that one can understand through introspection. If you ever analyze your own reactions to different situations, you will notice that they are often based on your feelings about past situations that you experienced in your life. Thus, you are likely to weigh strong feelings that you had over tepid feelings, and in this manner you may make appropriate or inappropriate decisions. In my view, this is about the best that most people can hope to do in most situations, and I think that some of the rationalistic models presented in economics and cognitive science, on close examination, may be little more than status-bestowing presentations to those who are currently successful, wealthy, or both. That is why I was skeptical of the Steven Pinker-Bill Gates alliance celebrating the triumph of reason at this stage in our collective history. I am inclined to think that humans have a limited capacity to understand much of anything, and although science is usually better than the alternatives, we may be incapable of truly understanding many highly complex phenomena.

For my purposes, I am happy that Goel brings up actual cases of public cognitive mistakes. He describes the fishing dilemma in the Canadian Maritime provinces from the 1970's to the 1990's. There was a precipitous drop in cod catches in 1974, and the Canadian government intervened and set limits on cod fishing. The cod fishermen rejected the quotas and applied political pressure to have them raised. As a result, by 1992 the cod population was practically eradicated, and the fisheries accordingly went out of business. This example shows how individual self-interest can backfire when people don't follow rational procedures for the benefit of a group as a whole. Goel uses this example as a parallel to the public's lack of responsiveness to warnings about climate change. I am hoping that he will have more to say about public irrationality in the remaining chapters, because that is probably the greatest problem of our time. The underlying issue is that human nature allows people to act in self-interest even when the long-term consequences of that behavior are extremely negative. In this instance, despite an effort by the government to protect the fishermen, their irrationality sabotaged the actions taken to assist them.

Although, in a practical sense, this is a more complete treatment of human cognitive limitations than that of the other authors I mentioned, I don't think that Goel will be extending the discussion as far as I would like. At the moment we have not only destructive autocrats making the world unsafe for millions of people, but also millions of people in democratic countries making poor choices about political candidates. This isn't a simple case of democracies being better than autocracies, because, as is clear from Goel's examples, either system can result in catastrophic mistakes. We are currently in a situation in which we have to worry not only about deranged autocrats, but also about deranged democratic voters. Faith in democracy is looking pretty misguided at the moment. It's as if we just wasted four years worrying about what the idiot who was elected president of the U.S. would do next, only to waste more time worrying about what the idiot Russian autocrat would do next. The Russian invasion of Ukraine has to be one of the stupidest and most destructive events since World War II.

I am approaching the end of the book and will wrap up on my next post.

Reason and Less: Pursuing Food, Sex, and Politics II

While, so far, I am broadly in agreement with Goel's model, I am not particularly enjoying the presentation, which includes a fairly detailed history of cognitive science, going all the way back to William James and covering B.F. Skinner in some detail. In the context of his argument, their ideas apply primarily to the associative aspects of cognition and don't account for reason. He is gradually working from the autonomic to the instinctive to the associative to the reasoning modes, and most of the research is dated. He also rehashes the more recent research of Daniel Kahneman, which I don't find particularly enlightening. And he quotes several philosophers, who, as you might expect, I don't think add much to the discussion. However, unlike Kahneman, he is including research from evolutionary psychology, which I find helpful, and he is open to seeing cognitive science through an evolutionary lens. Above all, more than any other books I've read, he is applying his model to important real-world situations, such as Donald Trump's first impeachment. The Republican "arguments" in support of Trump's innocence were primarily ad hominem attacks on his critics:

None of these responses address the coherence relation between evidence and conclusion, that is, the soundness of the arguments for impeachment. They all commit common reasoning fallacies, but they do so intentionally, consciously, rationally! The official impeachment counteroffensive relied on the calculation that most of the MAGA faithful would fail to accept any evidence of wrongdoing by the President, if universal in-group/out-group instinctual systems could be activated. The group we belong to is always good, pure, innocent, and of course beloved of God; the out-group consists of elites, socialists, Muslims, and others trying to destroy us and our way of life for nefarious purposes....

As straightforward as this analysis is, you don't generally hear it in the news media, which coddles the public to such an extent that popular public figures are rarely criticized. Because of this, the news media is actually encouraging public irrationality.

I won't attempt to rehash all of the details of the book as I read it, and I'll just throw out whatever thoughts occur to me. There is the omission of Kant among the philosophers whom he quotes, and I think that at the moment one of Kant's ideas is at the vanguard of biological research into cognition. In Born Knowing: Imprinting and the Origins of Knowledge, by Giorgio Vallortigara, the argument is made that chicks perform more sophisticated cognitive tasks than one would expect with a neural configuration based on a sort of template of the world, which they have acquired through evolution. In all likelihood, all animals have such templates, and the template of one species is likely to be similar to the template of another. What is interesting is that these templates probably originated through an evolutionary process in which natural selection permitted organisms to survive when they had a template that triggered behavior that was appropriate for real-world situations. In the case of mathematics, even chicks were able to make calculations without the use of language or symbols. 

Where Kant comes in is with his distinction between phenomena and noumena. Phenomena are the things that organisms perceive, and noumena are the reality behind their perceptions. The sensing organs of animals create perceptions, but animals have no direct access to the objects that cause them. Thus, animals, including us, behave as if the environment follows mathematical rules, but, since we lack direct access to reality, we can only know what our perceptions, which are produced by neural systems, tell us. According to Vallortigara, evolution is what caused these neural systems to exist, so it cannot be said, for example, that the world itself follows mathematical rules. We can only say that organisms with particular neurological arrangements survive, while others do not. Although this position does not contradict anything that Goel says, it places rationality in a humbler position than he seems to advocate.

Another area that Goel hasn't brought up yet in the book is the development of language in humans, as discussed in the books by Gaia Vince and Nichola Raihani that I covered earlier. I think that the existence of language alone explains most of what counts as human rationality and sets us apart from other species. Although language probably evolved for the dissemination of knowledge, it is probably the only biological feature available for engaging in the analyses which, on this planet, only humans are capable of making. So, in addition to the kinds of analyses that animals are able to perform in order to evaluate situations, the development of language, along with increases in brain size, allowed humans to engage abstract reasoning.

Reason and Less: Pursuing Food, Sex, and Politics I

I'm now underway on this new book by Vinod Goel, and will be discussing it for a few weeks. Goel is a Professor of Cognitive Neuroscience at York University, Toronto. This is the first book that I've come across that offers a comprehensive perspective on human cognition over a wide range of areas and addresses some of the associated real-world problems. My other readings have covered the same territory, but usually with a narrower focus: Daniel Kahneman and Richard Thaler tell us that we don't always think clearly and can improve ourselves with the help of libertarian paternalism; Steven Sloman tells us that we don't know much, but that we can get around that by cooperating with others; Robert Plomin tells us that our life outcomes are largely determined by our genes; Frans de Waal tells us that we're not much smarter than animals; and Robert Sapolsky chimes in to tell us that we're sort of stuck with our animal brains. Goel's view covers most of this territory, but his objective is specifically to develop a multidisciplinary model of how human reason is modulated by our evolutionary history, and how we can give reason the upper hand in real-world situations in which we behave irrationally to our own detriment. Because this book was not intended to be a bestseller and is more specifically academic, I am finding the discussion somewhat more interesting and theoretically useful than the others mentioned.

Goel's model is called tethered rationality and he describes it as follows:

The "animal passions," or nonreasoning behaviors in technical parlance, include autonomic behaviors, instinctive behaviors, and associative learning behaviors. These behaviors and their underlying mechanisms have been studied extensively over the past hundred years. They differ not only from reasoned behavior but also from each other. They are hierarchically organized in terms of appearance on the evolutionary tree, are integrated, and are widely available across species, including humans. Humans also exhibit reasoning or rational behavior, which (I will argue) is unique to us. However, it does not supplant the evolutionarily older behaviors. Reason evolved on top of them, but it does not "float" untethered above them; it is tightly integrated with both bottom-up and top-down connections. This means that human behavior is a blended function of all these systems, not just reason (or any other individual system). Humans have a reasoning mind, but it is tethered to and modulated by evolutionarily older associative, instinctive, and autonomic minds. 

I find this model more appealing than any others that I'm aware of. The System 1 and System 2 model used by Kahneman and Thaler is too oversimplified to be of much use, and it seems to me that, by advocating libertarian paternalism, they are inadvertently promoting a social hierarchy which favors the economically successful over the economically unsuccessful, and as a result they may actually be endorsing a two-tier social structure which, in the end, would become nothing more than a new measure of social status, i.e., rich = smart, poor = stupid. Sloman emphasizes human ignorance, but does not offer much of a solution. Plomin is primarily a genetic determinist, but also has little to say about the social implications of his work. De Waal is mainly an apologist for animals, and does not address human cognitive limitations. Sapolsky is well aware of the haphazard evolutionary construction of the human brain, but isn't interested in how this bears out in our political or other institutions.

Goel's objective in this book is broader, and he hopes to address some of the serious cognitive errors that turn up routinely in public life. He uses examples of persistent, scientifically confirmed errors, such as climate change denial and opposition to inexpensive healthcare systems, to show how unreason overpowers reason in our brains. However, in his defense of rationalism, he may not have answers to deterministic positions that Sapolsky and others may hold. He is operating roughly from the psychology/sociology/cognitive science group of fields, which generally hold that humans are the only truly rational species, despite somewhat intractable intrusions of irrationality. Although, in the end, he may only come up with a slightly more complete description of the modules of cognitive dysfunction than Kahneman was able to, of all the authors I've mentioned, he is the only one who seems interested in countering the ridiculous statements that pass for normal in national and world politics. 

To his credit, Goel also seems willing to take on some of the false precepts of political correctness. So far, like Robert Sapolsky, he has explained in detail why gender is not a social construct and is in fact determined by known biological processes. He also backs E.O. Wilson regarding the unfair attacks that he experienced with the publication of Sociobiology: The New Synthesis in 1975. As I've often said, liberals and politically correct people, then and now, have been unable to accept biological determinism as playing a role in our species – thus, ignorance still holds sway in leading universities.

Diary

I am currently going through another rethink on what to read and discuss on this blog. In the absence of any feedback, I am inclined to just do what I feel like doing. The main problem that I've encountered is finding a type of writing that doesn't become tiresome after a few years. I was already tired of fiction when I began this blog, and I have resigned myself to just dabbling in it occasionally. On the whole, I've had greater success with nonfiction, but while I have hardly exhausted the field, it is still difficult to find good writing in it. The main lesson for me is that if something is a bestseller, the chances of my liking it are nearly zero. I think I've had above-average success with biographies, but have already reached a point where there are few remaining biographical candidates who might interest me. I was stretching it to read about Diderot and Voltaire, and, at the moment, I'm drawing a blank about whose biography I might read next. I considered E.O. Wilson, who died recently, but decided against it. Prior to starting this blog, I read biographies of George Eliot, Mary Wollstonecraft and D.H. Lawrence, which I found informative, but I don't want to return to them. I have considered reading more memoirs, but so far I have found them to be more problematic than biographies. Most people lack the ability to write objectively about themselves, and, in my experience, a good biography usually provides a fuller and more accurate picture of a person – if the author is competent. For example, I now think that I understand Jean-Jacques Rousseau, Charles Darwin and Bertrand Russell far better than I would have if I had relied exclusively on their autobiographies. Also, after reading parts of Simone de Beauvoir's memoirs, I think that she started out extremely well with Memoirs of a Dutiful Daughter, but that her later memoirs declined significantly. In particular, she needed an impartial biographer to analyze the complexities of her later life. Her explanations of her adult relationships are extremely lacking, in my opinion. To my knowledge, a good biography of her doesn't exist, or I would read that. 

Speaking of biographies, I should mention that I don't read them the same way that many people do. I am not inclined to hero-worship, and I try to imagine what it would be like to be that person or to know him or her intimately. The circumstances of a person's life are evanescent, and it may therefore be pointless to attempt to emulate someone else, especially if they lived in a different era or on a different continent. What I usually notice is the opposite of a "destined for greatness" narrative, because many factors completely beyond the control of an individual determine the actual course of their life. You can see this in every biography that I've read, though it is more conspicuous in some cases than in others. Charles Darwin in particular might have had a completely different life. As I said, under slightly different circumstances, we might now be talking about Wallaceism instead of Darwinism. Although both Wallace and Darwin were quite able, Darwin's social standing gave him a significant advantage: without it, he may never have attended college, sailed on the Beagle or conducted any scientific research. Darwin was also extremely shy, and if he had never found others to perform the extroverted requirements of his career, Thomas Henry Huxley in particular, he could easily have languished in obscurity. While it is true that Darwin had considerable motivation not to be seen as a failure, which was probably due to his father's low opinion of his abilities, it seems very doubtful that he would have succeeded if he had grown up under Wallace's circumstances.

After reading several long books, shorter ones are beginning to look more attractive to me. I thought that Born Knowing: Imprinting and the Origins of Knowledge was very good, and would like to find more books like that. However, in order to locate that one, I had to rummage through several university press websites, which is a haphazard process. I've decided to resubscribe to The Times Literary Supplement, which, though it may not end up being useful, covers a very wide range of topics. I currently have a temporary subscription to the online New York Review of Books, which I don't intend to renew, since I still don't find their articles interesting or like many of their writers. In the current issue, they have articles by Paul Krugman and Martha Nussbaum, two writers whom I prefer to avoid. In any case, I will be trying to read slightly academic essays and short books instead of long biographies, such as Ray Monk's biography of Bertrand Russell, which took over six months to complete and probably brought my readers to tears in more ways than one. It is possible that more biographies, novels and poems will pop up here, but perhaps not often. If you have any preferences or recommendations, feel free to communicate them to me.

Anarchic Trends in Political Evolution

When I began this blog eight years ago, the impetus was my frustration with online publications and Internet discussion generally. I had noticed that American intellectuals had no influence on domestic or international policy and had merely been scribbling away during the War in Afghanistan, the Iraq War and the Tea Party movement without solving any problems and, quite rightly, being ignored. Since then, with the election of Donald Trump in 2016, the Capitol attack of 2021and the anti-vax movement of today, a much broader failure of traditional media is evident. Not only are American intellectuals irrelevant, but so are most newspapers, magazines and television news programs. This turn of events in the U.S., Canada and much of Europe is making the political order seem more unstable than it has been in decades.

As I've often said, it is appalling that Donald Trump was elected president. Of course, this was merely symptomatic of deeper social ills which have since then more clearly manifested themselves. First, it was greedy small business owners and disenfranchised blue-collar workers, and now it's also truck drivers and poorly-educated people in general. It has been dispiriting to observe the stodgy, pro-business Republican Party of 1950 evolve into an unhinged far-right organization that openly suppresses the democratic process and is supporting dishonest opportunists in order to gain political power. To be clear, I am not primarily in favor of democracy, and my preference is for rational laws based on the concepts of equality, human wellbeing and the preservation of the environment, along with the impartial enforcement of these laws. At heart, I'm a law-and-order advocate, and to me it is simply a matter of having the right laws and enforcing them. Currently, in the U.S. we are witnessing both the absence of necessary laws and a reduced emphasis on supporting the public good.

I am almost old enough to remember the privations that people suffered in England during and after World War II. When there were food shortages, people accepted rationing and grew their own vegetables when possible, without making a fuss. In the U.S. during the Great Depression, people met with privations far more severe than they have in recent years, and there was little sign of a revolt. This has caused me to think of modern Westerners as whiny spoiled brats. The phenomenon is currently showing up in the anti-vax movement. It is difficult for me to imagine a convincing justification for their actions. We have a situation in which a pandemic is killing people and adversely affecting world economies, and people are facing greater economic hardship. There are free vaccines that have been proven effective and are available to everyone. The anti-vaxers are both encouraging the spread of the coronavirus and disrupting their economies, and they are not offering an intelligible rationale for their behavior. In my view, the anti-vaxers who riot and block bridges ought to be arrested, because they are acting against the public interest without any mitigating circumstances.

Actually, in a sense I am an advocate of totalitarian regimes, and, for me, we are going through an interesting period in which we have an opportunity to compare and assess the efficacy of both totalitarian and democratic regimes. In the West, I think that the Internet, along with ineffectual political leadership, have already seriously damaged a system that was once capable of sustaining and protecting the inhabitants. The Internet itself is rather innocuous, and the difficulties that it has created result mainly from the fact that it transmits multiple ideologies and worldviews, which have not been filtered or edited, resulting in a large assortment of incompatible worldviews within the population of each country. When you consider that humans are fundamentally irrational, this is a perfect scenario for the breakdown of society into cult-like groups which understand neither themselves nor other groups and may even inhabit fantasy worlds (see "Pizzagate"). The existing totalitarian regimes now have a significant advantage if they can both sidestep democratic processes and filter alternate worldviews from their Internet services, while also meeting the needs of their citizens.

Although I'm obviously not an expert on Russia, I don't think that its political model is sustainable. Vladimir Putin is essentially a dictator backed up by a powerful group of oligarchs. Russia's economy is not diverse compared to that of Europe, which means that it can never generate comparable wealth. Add to this the fact that Putin and the oligarchs are probably hoarding much of the wealth, and that the Internet also works against them, Putin's days seem numbered. At the moment, he is reflexively bullying his neighbors because of political weakness in both Europe and the U.S., but he has no discernible end game and no suitable replacement for himself. If he doesn't trigger a nuclear war, history will see him as an insignificant Cold War carryover.

I am also not a sinologist, but I think that the outcome in China will be far more consequential. Xi Jinping resembles a dictator, but he is operating in a political system that is quite different from that of Russia. If he is corrupt at all, it is at a much lower level than that of Vladimir Putin. He has also led a campaign to root out corruption. As I said earlier, I don't think that Western individualism ever caught on in China, and it is possible that Xi is actually working for the good of the people. Westerners collectively get upset about China's treatment of the Uyghurs, but Xi's strategy for dealing with them may be justifiable. In China "the people" is a meaningful concept, unlike the U.S., where it has never been more than part of convenient political slogans. I'll allow that Xi and his government may be overreacting to the problems that Islamic groups have caused elsewhere over the last few decades. In any case, the main advantage of totalitarian regimes is that they can use brute force and take immediate actions to correct perceived risks. The question is whether an action is appropriate and whether it entails corruption of any kind. My view is that "the people" are paramount, and that it is the duty of the government to protect them, even when that requires the curtailment of a minority group. Also, I might note that the Uyghurs as a group are not universally discriminated against in China; we know a Chinese Uyghur who is a student at Middlebury College and whose father is a successful executive in the oil industry. 

My impression of China is that it is more amenable to a cooperative mindset than most Western countries. This is partly the result of ancient social conditioning and partly the result of exposure to decades of communist propaganda. As in the West, China is vulnerable to ideological intrusions from the Internet, but there is little sign, except in Hong Kong, that protest is widespread. The potential problem for Xi Jinping would be to make missteps that cause dissent in pockets of Chinese society. At this stage, protest is hardly evident, and Xi could be given credit for controlling the COVID-19 outbreak better than any Western country. If Xi is also able to maintain economic stability over the next few years, he could become more respected than any Western leaders have been since World War II. I am a little suspicious of his current alliance with Vladimir Putin, but it is possible that it is merely a case of short-term political expediency. As a new phase in my interest in governance by artificial general intelligence, I am imagining Xi as a robot that is controlled by AGI and becomes the world leader without anyone suspecting that it isn't human.

Regardless of my speculations on China, I think that the political situation in the West is beginning to look dire. Political leaders here are increasingly forced to solicit campaign money from corporations, which don't generally act in the public interest, while at the same time soliciting votes from an uninformed public that is being barraged with misinformation. It is possible that Western governments will address the divisive effects of the Internet, but it seems unlikely that that will occur soon, because, in the U.S., Congress currently can barely even agree to continue funding the government.

Diary

We're having a more normal Vermont winter this year, which is what I prefer. If there isn't at least a foot of snow on the ground and the temperature never hits -20, something feels wrong. The only problem is that, with COVID-19, you get sort of a double-cabin-fever effect. Fortunately, we are able to socialize a little and had someone over for dinner last night. COVID is declining rapidly here, and it looks as if this spring will be similar to last spring, with activities widening again. The winter is a problem for William, though. He doesn't spend much time outdoors hunting when the snow is deep and, because he is wilder than most cats, he gets restless indoors. He doesn't lounge around, look at birds through the window or play with cat toys. He eats too much and gets fat. The first winter that we had him, he was incautious and spent so much time outdoors that his ears froze, but now he is more careful. He has to be locked in the basement for much of the day because he can be a real pest. I've cleared away the snow from his cat exit, and he goes out on his own when he likes. I don't think he's caught a mouse since November or December, whereas he often catches two or three a day during the summer. They are still out there, and you can see their tracks in the snow.

Over the last few winters I've usually had longer books to read. Now that I'm finished with Voltaire, I'm also getting tired of the Enlightenment. When you look closely at the past, you can clearly see how historians have oversimplified and idealized it: they like to create national myths with heroic figures and, especially in the U.S., to congratulate their forebears on their wisdom. A more thorough investigation usually indicates that there was actually little wisdom to be found, and, if there was any, it may already have been forgotten. This is why I have always found it difficult to take historians seriously. The French Revolution occurred not because the philosophes enlightened the public, but because the monarchy and the Catholic Church governed very poorly. The problem of poor governance has never been solved, and many of the same risks exist today. While the separation of church and state is still technically holding up in some countries, if you broaden the definition of "church" to "baseless ideology," practically nothing has changed in three hundred years. France was like a medieval kingdom until 1789, and, though I often prefer French culture to English culture, at least the English were able to remove both the monarchy and the church with less violence. What we are witnessing now are overpopulation, climate change and increased wealth inequality, and, among the competing ideologies, there is no frontrunner. There are still monarchies, theocracies, dictatorships and oligarchies, and although some of the democracies are wealthy, wealth inequality is causing political instability. I find it embarrassing to live in a country led by an inarticulate Catholic president, with a demonstrably corrupt and incompetent figure dominating the other major political party. If this were a rational country, presidents would never attend church services and Donald Trump would be in jail. Meanwhile, the masters of the universe in high-tech industries are either getting divorces, making ridiculous plans to colonize Mars or creating products for consumers to live in fantasy worlds full-time.

I have some books on hand to read, but at the moment most of them don't appeal to me. I just started on The Collected Stories of Katherine Mansfield, because I still like her writing a lot. This book includes The Garden Party and Other Stories, which I read and discussed earlier, and I may discuss other stories after I've read them.
