Sharing meat

When I was first thinking about setting up the Thinking Meat Project web site, I was talking with my older son about some of the ideas behind the phrase “thinking meat”. I said something about how one of the ways we deal with the indignities and sorrows of being conscious animals is by sharing our experiences, in particular through art. When we learn about other people’s stories and their emotions, we at least know that we’re not alone. “Sharing meat,” Greg said.

This New York Times article by Daniel Goleman talks about the ways that human brains can share mental states and affect each other’s physiology. Goleman sums up the opinion of two researchers in the field thus: “emotional closeness allows the biology of one person to influence that of the other”. Goleman talks about mirror neurons, mood contagion, and how these might be related to the physical health benefits of being happily married and having a circle of good friends. It’s fascinating stuff; I’d like to see more research into the mechanisms involved and the specifics of how health is affected by the emotional climate around us.

Book review: For the Time Being

My younger son recently discovered Annie Dillard’s books and recommended several of them to me, including For the Time Being. Before I had a chance to read it, I took a weekend trip to Chicago to see, among other things, the King Tut exhibit at the Field Museum. The exhibit was impressive and oddly moving. I was struck by how many of the artifacts were meant to protect the dead in their travels through the next world. All that time and effort and money spent on the safe passage of dead rulers through an imaginary afterlife! Why? When I expressed that thought to Patrick in an email message, he said that I really ought to read For the Time Being, because in it Annie Dillard shares similar thoughts on the Chinese emperor Qin, who was buried roughly 2,200 years ago with thousands of life-size clay soldiers.

So I went to the library and checked out a copy. It’s a difficult book to sum up, but here are some of my thoughts. For the Time Being is a loosely linked collection of beautifully written essays. The topics that recur in each set of essays include birth defects, human population statistics, Eastern European Judaism, sand, clouds, the life and work of Teilhard de Chardin (paleontologist and priest), and Emperor Qin and his clay soldiers. The themes that tie this diverse material together are our mortality and vulnerability, and the tension between our feelings that we and those we love are uniquely special and important, and our knowledge of the vast numbers of other humans, past and present, with whom we share the planet.

I had a hard time coming to grips with a lot of the Jewish theology, because I don’t believe in God and thus see no reason to try to figure out his attributes or motivations. Sometimes I can see spiritual or religious ideas as metaphors and gain some understanding from them even if I can’t take them literally, but most of the theology that Dillard covered left me fairly cold. I’m sure my understanding of the book would benefit from a second reading, and maybe I’d see how the theology fits into the rest of it.

I did, however, find many Thinking Meat sorts of themes in the rest of the book. Dillard uses lovely images from nature as metaphors for the constant turnover of human generations:

“Our generations rise and break like foam on shores.”

And this, about the standing wave in the wake of a boat:

“Each crest tumbled upon itself and released a slide of white foam. The foam’s individual bubbles popped and dropped into the general sea while they were still sliding down the dark wave. They trailed away always, and always new waters peaked, broke, foamed, and replenished.”

And the clay soldiers are human simulacra that reflect the way we rise up out of the earth and return to it. The knowledge of the rising and falling of the generations and our own small place in the stream of humankind is not always comfortable:

“Huston Smith suggests that our individuality resembles a snowflake’s. The seas evaporate water, clouds build and loose water in snowflakes, which dissolve and go to sea. The simile galls. What have I to do with the ocean, I with my unique and novel hexagons and spikes? Is my very mind a wave in the ocean, a wave the wind flattens, a flaw the wind draws like a finger?”

The statistics that thread through the book emphasize the sheer numbers of humans; some of the statistics are about disasters (like a typhoon that hit Bangladesh in 1991 and killed 138,000 people) or other occasions of mass death like the atrocities of Pol Pot’s and Stalin’s regimes. Throughout the book Dillard asks how we can continue to find human life sacred and feel the magnitude of the loss when the numbers become mind-numbingly huge. To be truly aware of the individuality of each person lost in a catastrophe (or the humanity we share with babies born with birth defects, especially some of the more horrifying ones she describes) is too heart-rending. She quotes Ernest Becker, who said that “a full apprehension of man’s condition would drive him insane.”

I understand what she means. It strikes me that one of the most heartbreaking things about 9/11 was the way we learned a lot about many of the victims, not just their names or their jobs but little quirky things about who they were. The New York Times, in its “Portraits of Grief” (later gathered in a book) provided glimpses of the ordinary lives that were ended so abruptly. My mother died not quite a year before 9/11, and the stories about each individual’s story and family brought home to me that the loss and the grief that we felt was multiplied by so many families who suffered losses that day. It’s too sad to think about for very long.

And yet we never want to forget the people we love who have died. All we can do now is hold them in memory in all their specificity. And one of the ways we value our own lives is by remembering and cherishing even the smallest details of existence. Dillard gathers together a surprisingly large number of reports of clouds, observed and recorded by John Muir, John Constable, Gerard Manley Hopkins, and others. “Why seek dated clouds?” Dillard asks. “Why save a letter, take a snapshot, write a memoir, carve a tombstone?”

That consciousness of posterity and the wish to leave things behind that people will remember us by is totally human but in the very long run, of course, it’s unrealistic. Dillard writes about the hominid footprints discovered in Tanzania by Mary Leakey; these were likely left by three of our distant Australopithecus ancestors, a man, a woman, and a child. The footprints were preserved for millennia by fortuitous circumstances, and it’s proving unexpectedly difficult for us to continue to preserve them. What struck me the most, though, is that for all our contemporary efforts to leave traces of ourselves behind, Dillard points out that even though we don’t know where those hominids were going or why, or why the woman hesitated at one point, “We do know we cannot make anything so lasting as those three barefoot ones did.” Did I mention that the book tends toward the melancholy, and is not always easy to read?

The urge to preserve our memories and the material objects that tie us to them is related to our belief that we and our times are special, and I feel it as strongly as anyone. That’s one of the reasons I write (to capture what it’s like to be here at this place and time). But it’s also one reason I read (to learn what others have to say about their places and times). Dillard talks about whether we really do live, as we often feel we do, at a special juncture in history; she says our times are “ordinary times, a slice of life like any other”, and that we are “[o]rdinary beads on a never-ending string”. “New diseases, shifts in power, floods! Can the news from dynastic Egypt have been any different?” We resist that thought just as we resist the idea that our individuality resembles a snowflake’s.

The book is so diverse and episodic that it’s hard to sum it up, and I’m sure that a second reading would bring different facets of it to light. One of the images that stays with me the most poignantly from this reading is that of a nurse washing newborn babies in something of an assembly line procedure. (I love Dillard’s description of an obstetrical ward in a hospital as “…surely the wildest deep-sea vent on earth: This is where the people come out.”) The image of the continuous stream of babies, picked up at one end of a counter, bathed and dressed and wrapped snugly in a blanket and then set at the other end, is balanced by the way the nurse addresses each baby as she picks it up: “Now you.” That image provides one way to sum up the book: it’s a beautiful if often disturbing exploration of the tension between the realization that we are beads on a never-ending chain, and our need to address each other in the moment as a specific and irreplaceable “you.”

Book review: Authentic Happiness

Martin Seligman is the founder of the Positive Psychology movement, a shift in attention to the psychology of functional rather than dysfunctional states of mind. Rather than asking how to heal the troubled, Positive Psychology asks how to help people make their lives as good as possible. Seligman has written several books that shade over into self-help, although his work and his recommendations are much better supported by research than many other self-help books. Authentic Happiness: Using the New Positive Psychology to Realize Your Potential for Lasting Fulfillment takes the somewhat fuzzy concept of happiness and dissects it neatly, linking happiness to the development and exercise of character strengths.

Seligman describes the various contributors to happiness (your characteristic set-point, your circumstances, and your voluntary control over your thoughts). He makes the point that a set-point is actually more like a range, and you can often move to the high end of your range even if you can’t change the range itself.

The data about which circumstances matter, and how much, were particularly interesting. Education, race, climate, and gender, for example, seem to have little effect; life satisfaction rises with age, which pleasant affect (good feelings) rises slightly and negative affect stays the same. Religion is linked to optimism for the future, which in turn is linked to happiness. (The more fundamentalist the religious beliefs, the greater the optimism. So are fundamentalists happier? I can’t remember if the book said this straight out, and even if they are, I’d still rather be an atheist.)

A “rich and fulfilling social life” was linked to happiness, although the cause-and-effect relationship is not clear (are people happier because they socialize more, or are happy people more likely to socialize, or is there some other factor underlying both the happiness and the socialibility?). Time spent alone is one of the measures of what kind of social life you have, which leads me to wonder how introversion is taken into account. What looks like an abundant social life for someone like me, who needs a lot of time alone, might look pretty sparse to an extrovert, but it could still be plenty rich and fulfilling.

The voluntary factors take up a good deal more of the book than the discussion of circumstances and inherent capacity for happiness. Seligman suggests that we can feel happy about the past, the future, and the present. He describes some ways to cultivate more positive thoughts and feelings about the past (gratitude, fulfillment, pride, serenity) and the future (optimism, hope, faith, trust), but the bulk of the advice is about cultivating happiness about the present. He makes the distinction (crucial in my opinion) between pleasures and gratifications. The former he divides up into bodily pleasures and higher pleasures; they are “about the senses and the emotions”, and they are subject to decrease through habituation. Building up the habit of savoring our pleasures, perhaps limiting our indulgence in some of them, and practicing mindfulness are ways to counter this decrease.

The gratifications, on the other hand, are “about enacting personal strengths and virtues”; they might not always feel good at every stage of the process, but they provide the deep satisfaction and fulfillment that Seligman sees as essential to happiness. He suggests that the pleasures are the reward for doing something that’s good for the body, and gratification is the reward for building up psychological capital that benefits us mentally. The personal strengths and virtues that we exercise are part of what used to be called character; Seligman believes that character needs to be resurrected as a viable concept in the social sciences. He describes a search for positive character traits that are valued in religions and cultures all through recorded history and around the world; the search identified wisdom and knowledge, courage, love and humanity, justice, temperance, and spirituality and transcendence. He describes the 24 character strengths associated with these six virtues; everyone, he says, can work to improve these strengths in themselves, and applying these strengths to the situations in your life is what will bring you gratification and happiness in the present.

You can take a quiz in the book or online at the Authentic Happiness web site that will give you a listing of your top strengths. The ones you identify as your signature strengths—that appear high on your list and that feel the most integral to who you are—are the ones you should strive to find ways to use in your job and in your personal life. The three penultimate chapters describe applying this knowledge in your job, in your marriage, and in parenting.

The final chapter was, I have to admit, a major disappointment. I thought that applying your best characteristics to a worthwhile goal here in this world is a noble enough path to take through life and not a bad way of spending your time on this planet. Being part of the human race, part of the life of the planet (and trying not to be such a destructive part), and part of the universe gives plenty of meaningful context to my life. However, Seligman in his final chapter suggests that there is something more to aspire to. He mentions Robert Wright’s Nonzero: The Logic of Human Destiny, which suggests that evolution is proceeding toward a goal, and that humankind is evolving toward a future of greater cooperation (win-win games, rather than the zero-sum win-lose games that characterize so much human interaction) and that we will outgrow our less lovable behaviors like greed and hatred. (I haven’t read the book, so I’m summarizing what I’ve learned about it from Seligman’s book and from reviewers. I’d love to hear from anyone who has read it.)

Seligman’s take on this is that maybe the negative emotions are there to warn us away from things, and the positive emotions are there to tell us of opportunities for cooperation and growth, although I’m still unclear about why the latter should come to predominate over time. Seligman says that if you take God to be omniscient, omnipotent, and good (leaving out the creator aspect which has caused so many theological conundrums), maybe that’s what humanity is evolving toward. Personally I don’t need for humanity to be evolving toward godhood in order to feel like my life has plenty of meaning and purpose, and I was disappointed that a book that was overall so grounded in research should drag these religious speculations in toward the end. (Being here is enough!) Still, there was some good information in the book and it was worth reading for the ways it clarified some of the concepts involved and summarized some relevant research.

Gratitude

A few weeks ago, I was talking with a friend about gratitude; when I’m in a beautiful place, or looking at the starry sky, or feeling particularly appreciative of the physical processes that resulted in my presence on the planet, I feel grateful. I don’t believe in God, so I don’t know who to feel grateful to, but I still identify the feeling as gratitude. My friend thinks that gratitude has to have an object, a person to be grateful to; he thinks the fact that I label these feelings gratitude (rather than apprecation or joy) is a remnant of my Catholic childhood.

I’m not sure that’s it, though. For one thing, when I was a Catholic, I didn’t understand very much of the processes that gave rise to stars, and solar systems, and planets, and in particular to the earth and the life on it. I didn’t appreciate the web of living creatures that make up the ecosystem on which I am utterly dependent, and I didn’t have a clue about the number of conditions that had to be just right for complex and eventually intelligent life to arise here. Oddly enough, when I was told to believe that a divine creator had made us and the earth for us to live on—i.e., when I did have a person to be thankful to—it was a lot harder to feel the requisite gratitude, perhaps because God so often seemed to hedge life around with difficulties and punishments and fear. And somehow it didn’t seem all that miraculous to be here if we had been created by an intelligent being; the wonder of existence, to my mind, becomes obvious only when you realize the backdrop of an immense and mostly lifeless universe.

Coincidentally, I recently ran across an essay by Ronald Aronson in TPM Online in which he addresses the question of who atheists and agnostics feel grateful to when they feel thankful for the good things in their lives (and whether it makes sense to call it gratitude in the first place). His take on it is that the object of gratitude need not be a single individual, but can be impersonal forces:

It is a way of acknowledging one of our most intimate if impersonal relationships, with the cosmic and natural forces that make us possible.

He sees gratitude as related to dependence, and as an acknowledgement of our dependence (on previous generations, on other creatures on the planet, on those we don’t know who labor to make our lives possible, and on the natural processes that support our continued existence). I really like that idea, and the idea that gratitude doesn’t have to have a personal object. I’ve thought quite a bit about why I don’t think of my feelings as appreciation or happiness rather than gratitude, and I think the element of recognizing dependency is part of it. I also like Aronson’s efforts to be clear about what we’re talking about and not lapsing into fuzzy references to a sort of pseudo-God; he quotes a passage from Attitudes of Gratitude by M.J. Ryan that talks of the “Great Spirit”, and I remember with equal distaste the convocation prayer at the commencement ceremony when I graduated from IU, which called upon “the weaver of the web of life”.

The idea of gratitude having an impersonal object didn’t cut much ice with my friend, although it did spark some interesting discussion between him, me, and my older son Greg. Greg pointed out that although we think of “gratitude to”, the idea of “gratitude for” is at least as interesting, and that the times when a religious person would be thanking god is maybe when an atheist is feeling grateful to the universe for the universe—i.e., the object of both prepositions is the same. He also said, in email to me:

I think anyone who can feel gratitude to the intricate and boundless beauty of creation without relying on the crutch of mysticism has probably already learned most of what psychedelics have to teach.

Finding his long thoughtful email message in my inbox certainly made me feel grateful (both to and for Greg). I notice that there’s something of a continuum as far as identifying a person to be grateful to. When you’re enjoying time with people you love, you’re grateful to/for them. When you’re enjoying a good meal in a restaurant, maybe you’re thankful to the people who cooked it. Last weekend I stood in the Art Institute in Chicago admiring one of Monet’s paintings (Bordighera, one of my favorites), and I asked my friend if he thought it made sense for me to be grateful to Monet for painting it, even though he’s dead now. He said that made sense to him. Aronson discusses both gratitude toward people who are unknown, not present, or long gone, and gratitude toward the impersonal forces of nature, which makes sense to me, but I suppose there’s a dividing line there that might be a point of contention for those who disagree with him.

I’d be interested in hearing other people’s comments on this; an atheist friend has already told me that for him the question doesn’t arise because he doesn’t feel gratitude toward nature (just appreciation). I’m curious about what other people think. Meanwhile, it’s time for dinner, a meal for which I’m sure I’ll be grateful.

Mysticism in the brain

Two Canadian scientists have used fMRI to examine the brains of nuns who were recalling mystical experiences. Prior research seemed to indicate that maybe the temporal lobe is the only region involved in this type of religious experience, but these brain scans revealed that a network of brain regions were active, including the caudate nucleus, the temporal cortex, and areas that are believed to integrate physical input from different parts of the body. Here’s an article from news@nature.com.

I’m all in favor of finding out what’s going on in the brain during mystical experiences. I’m very curious about this, partly because I’ve had what could probably best be described as mystical experiences and I don’t think of them as having anything to do with a deity (in which I don’t believe). I’m curious about what’s going on and I wonder why the human brain has this capacity. I think of my own experiences as being times when I step out of the narrow horizons of daily experience and realize that I’m connected to something much larger, namely, the web of life on this planet, or the rest of the universe and the natural processes that gave rise to it. Religious people identify their experiences as communion with god, but I’d love to see someone examine atheists like me who happen to have mystical experiences, to see if it’s the same parts of the brain that are active. I’d bet they are, and it’s just the way we interpret the experience that differs.

I was not sure what to make of a suggestion one of the researchers made (mentioned toward the end of the Nature story) about possibly making a machine that could put the brain into the same state the nuns were in when remembering their mystical experiences. The nuns were observed while they were remembering a mystical state rather than when they were in one because it’s hard to call up such a state at will, and I know it’s not like you can flip a switch and turn it on. But on the other hand, for centuries religious traditions have been working on ways to cultivate the conditions necessary for such a state, so it’s not like we don’t have any idea how to get there. I can see why the suggestion of mechanically producing a mystical experience would unsettle a believer, but when you think about it, what’s the difference between that and meditating or praying or using entheogens (psychoactive substances that produce religious experiences)?

About the Thinking Meat Project

Note: This originally appeared as an About page on the Thinking Meat Project after old content was pruned. I changed it to a post so it could be moved over in chronological order with all the posts.

I used to use the handle “Thinking Meat” on a call-in quiz show on the local public radio station; my pseudonym was once read on the air as “Stinking Meat.” I can’t blame the announcer; the concept of thinking does not always seem to go with the concept of meat. We humans are both, though, thinking beings and meat: animals who are capable of thought and who are also bits of matter subject to all the physical forces and limitations that affect other bits of matter (not to mention the fact that we sometimes overrate or misunderstand our own thought processes). This blog is about the ways we understand and deal with ourselves as matter that can look at and think about itself.

This site covers a wide range of subjects, including evolutionary biology, psychology, cognitive science, linguistics, astrobiology, history, and literature. The emphasis is generally on the subjective experience or interpretation of what we have learned so far about ourselves and the universe that gave birth to us.

I use the concept of meat somewhat figuratively here, of course. (One consequence is that I occasionally get requests from advertisers who want to tout their steaks and chops here.) Years after I started using the phrase thinking meat to loosely describe the theme uniting the topics I cover on this web site, I discovered Terry Bisson’s wonderful short story They’re made out of meat, which also uses the term thinking meat to capture the idea from a unique and witty angle.

I began posting here in March 2005. However, I’ve pruned away some of my earlier posts. Many of them consisted of only a little text and a broken link, so they’re not much use any more. In addition, for a while the Thinking Meat Project somehow got slotted into the category of “brain blog,” although my focus was originally intended to be much broader. Because there are so many excellent brain blogs by professionals, I didn’t see any reason to keep many of my old brain posts around. I also see a lot less use these days for breathless press releases and news stories about the latest in psychology, so many of those posts have been retired.

Bogus brand recognition

I’ve been so wrapped up in buying and moving into a house that I have not had a whole lot of spare time on my hands lately. Thinking Meat is busy thinking about lawn mowers and curtain rods and floor beams, and going through the predictable cycle of jettisoning some of the things I’ve accumulated while simultaneously spending large sums of money at Target and Lowe’s to accumulate different things.

So I’m especially grateful to a friend for pointing me to this news story about bogus brand recognition. A recent study describes two experiments in which solving an anagram before being exposed to a brand name made participants more likely to think they remembered seeing the brand before, and to prefer the brand. The idea is that maybe something about the mental click of recognition that arises from correctly processing the anagram is transferred to the brand. The article describes this as a potential sales ploy; by manipulating people’s memories, marketers can sell us more stuff.

Well, OK, I guess that’s inevitable, and this isn’t the first story about brain science that I’ve seen in which influencing people’s buying behavior seems to be the point. But as we learn more about the ways our brains can trip us up, I hope we also see some activism and education aimed at helping people resist whatever the advertisers dream up to entice or coerce us.

Psilocybin revisited

After a 40-year hiatus in scientific research on hallucinogenic drugs, scientists are investigating the effects of psilocybin, a psychoactive compound found in some mushrooms. Of 30 adult volunteers who received psilocybin in a recent study, two-thirds of them described the resulting experience as one of the five most meaningful experiences of their lives. Some of the volunteers reported negative feelings, but many of them found intense spiritual meaning, which in some cases seems to have had long-lasting after-effects. The researchers warn that the negative effects could be harmful outside of a controlled setting (they don’t want everyone to rush out and experiment for themselves), but the value of examining the workings of psilocybin scientifically is such that it’s too bad this has been sidelined for so long. I hope we learn a lot more in the future about how psilocybin acts to create mystical states, and also how those states occur spontaneously. I wonder what it feels like to take it, but on the other hand I have had some pretty powerful spiritual experiences while under the influence of nothing more than a beautiful place, awe-inspiring music, or an exceptionally dark and starry night sky. I wonder what mechanism in my brain is capable of such transcendence, and why certain circumstances can trigger it in some people and why certain chemicals can also trigger it. To me this seems to indicate pretty clearly that spiritual states are something that arises out of our brain chemistry and not from the presence of anything supernatural, which is no surprise. I’m just curious about how it works.

You can read about this in a number of places, but I enjoyed the coverage in the New Scientist.

Déjà  vécu

I’d never heard of déjà vécu before, but according to this article from the New York Times Magazine, it’s an especially intense and/or recurring version of déjà vu. Déjà vu (already seen) is an odd sensation of recognition for a situation that in fact is novel; people generally know that the feeling is inaccurate and that they haven’t really been there before. In déjà vécu (already experienced), people can’t tell that a situation is new; they believe they are reliving a familiar experience. (It got me started wondering about how we do tell the difference between a real memory and déjà vu, or between dreams and reality.) The article talks about memory in general and its relationship to consciousness, summarizes the theories about why déjà vu happens, and discusses what’s different about déjà vécu. I was struck by the description of déjà vu:

Occurring at seemingly random times, lasting from a few seconds to a few minutes, it often comes with a feeling of approaching premonition. Not only does the situation feel familiar, but a vision of the future also seems just beyond the searchlights of your conscious mind.

I hadn’t heard much about that feeling of being just on the verge of seeing the future, but I’ve felt it, and this seemed an uncommonly apt description of it. I have felt that if I could just remember a bit more, I’d know how things will turn out, or what will happen next. It’s an uncanny sensation—one of the stranger aspects of being thinking meat.

Happiness seems to grow as we age

Hardly anyone wants to grow old (although it beats the only available alternative), but the results of a recent survey indicate that, contrary to popular belief, people grow happier as they grow older. Overall the survey participants of all ages expected older people to be less happy, but in fact the older people in the survey rated their happiness at a higher level than the younger people in the survey rated theirs. Curiously, people generally think that they themselves are likely to be happier than the average as they age, but that everyone else will grow more miserable. This press release doesn’t explicitly state whether the older people remembered themselves as happier at 30 than they are at their current age. It would also be interesting to see a follow-up study where the younger people in this survey are asked again decades from now to rate the happiness of their younger selves, and to see how the ratings they gave now compare to what they say when they’re looking back at this time.
