Brain / Mind ... Science ...

I finally started digging into “Godel, Escher, Bach” by Douglas Hofstadter. This is a big book; over 700 pages. And it’s mostly about math. Well, really it’s about “meta-math”: the bigger ideas behind math. But in order to get to the bigger ideas, the reader has to wade thru a lot of stuff about ordinary math, the kind of stuff that you sat thru in high school and freshman year in college, bored out of your skull. Mr. Hofstadter tries to make it as un-boring as possible by telling entertaining stories and presenting little ‘brain-tickler’ puzzles and hosting a fairly wide sample of artistic works by Escher (those crazy drawings that defy the normal rules of dimensionality and gravity). And he wants to convince you that math is the foundation of human consciousness.

I’m only at page 110, but so far I can’t see how a group of conventions regarding sets and axioms and theorems are going to explain why I think there is a ‘me’ inside of me. But that’s just it, Hofstadter would say. Consciousness is all about chasing your tail, about looping around without any starting or ending points. And that’s just what a lot of mathematicians have been thinking about over the past 100 years or so. Well, all this recursive math stuff is pretty interesting, but I’m still not sure that it’s going to bring me any closer to the mystery of subjective mental experience than the various neuroscientists, psychologists and philosophers, whose books about the mind and consciousness line some of my shelves. (Or sit on my floor – I don’t exactly have a nice, neat library here in my dinky apartment).

Hofstadter is enthralled with Bach’s musical works, because of the complex relationships between the various musical patterns that interweave cleverly through many of his compositions. I can’t say that I’m a big classical music fan; and even the Bach that I have heard . . . . well, let’s just say that I’ve thus far failed to appreciate the genius behind it.

The best song that I know of which deftly intermixes a group of wandering musical elements is a guitar instrumental by The Ventures, from their Live in Japan ’65 album. The song in question is a 3 and ½ minute medley of three Ventures hit songs from the early 60’s: Walk, Don’t Run; Perfedia; and Lullaby of the Leaves. It uses the standard 4-man pop tune setup typical of the mid-60’s: drums, lead guitar, rhythm guitar and base, i.e. the same line-up that the Beatles and their imitators made famous. But I’ve never heard a song where each musical element is so distinctive and independent, and yet plays off the other three so well. When listening to Medley, you can easily pick out one instrument and follow it all the way through. Even rhythm guitar, something that you hardly notice on most “fab four” songs, is a distinctive contributor to Medley. Each player gets his moment in the spotlight (even Bob Bogle on bass fills in the weak spots with some fantastic rides). But at just about every point in the record, each player is present, working away. I’m not sure about the math behind the notes on Medley. But my conscious mind tells me that there was some real genius at work in putting it together.

One more thing about the Ventures versus Bach: most classical work is quite complex but rather slow tempoed. Medley moves along at a lively clip. There isn’t much room for error. It’s kind-of like a race car ballet, moving along at 150, everyone hoping that everyone else gets the moves right and doesn’t crash. Maybe that’s not a bad way to think about how our minds work – at least when they work right. Every now and then they go crash, and all the notes in life are off-key. At least three-fifths of my typical work-week goes like that! And not like Godel, Escher, Bach, and The Ventures.

Art & Entertainment ... History ... Spirituality ...

Do you remember Steppenwolfe? The rock band, that is? I do. But to be honest, I wasn’t much of a fan of theirs. I didn’t like the name, didn’t like the music, didn’t like the concept; a bit too primal for me (although I guess that’s what rock is supposed to be). And I especially didn’t like the nasty looking beast with the long teeth on the cover of their albums. (Footnote — they were originally called “The Sparrows” — but who would take seriously a song from The Sparrows entitled “Born to Be Wild”?)

Well, I was reminded of Steppenwolfe the other day while reading a short article about the Vikings and their metaphysical beliefs (not the NFL team from Minnesota — their metaphysical beliefs are no doubt mostly financial in nature). The ancient Norsemen did indeed believe in an afterlife, and your status in that afterlife depended on how tough you were here on earth. That’s not too surprising. If you were a brave and valiant warrior here on earth, you’d go to the best place in heaven, a place called “Valhalla”. Notice the word within that word: Val – HALL – a. (Only the tough guys went to Valhalla; dweebs like me got put off on some ice-covered island out near the celestial Arctic Circle, something like Spitsbergen.) The Vikings literally saw heaven as a great big banquet hall. A place where the great warriors would gather with their valiant king in a continuous eating and drinking festival. There might even be some bawdy women there too. All kinds of action up there in that great hall in the sky. Sounds like a place that a wolf could appreciate.

And actually, that was part of the legend. The great legendary king of Valhalla (I forgot his name) was fond of saying that “the wolf is watching the hall”. Just because someone got to heaven doesn’t mean that their days of war are over. Not for the Vikings! A great battle between the primal forces of nature, represented by some big wolves, and the men of the hall, was yet to come, according to the Nordic mythology. And it wasn’t gonna be a little scuffle either. Men were going to get killed – once again! Dang those Vikings; even heaven for them was a place of great battles and bloody death.

That’s what the whole Steppenwolfe concept seemed to be about (to me, anyway). Thus, I was relieved the day that I was in some record aisle of some department store, and I saw the cover of Steppenwolfe’s break-up album, “Rest In Peace” It showed a gravestone saying “Steppenwolfe, 1967 – 1972”, with a little picture of that toothy wolf on it. The wolf was dead now; it wouldn’t menace us any more. (Actually, Steppenwolfe did come back together, but it wasn’t the same wolf anymore. No one took them or their albums seriously at that point.)

But if the Vikings were right, Steppenwolfe is still out there, lying in wait in the snows outside that great party hall way up in the sky. Yes, one can almost hear “Magic Carpet Ride” playing as burly warriors feast on sides of beef and mutton, brandishing huge pewter mugs of ale . . . . arg, greasy meat, sweaty guys with horned helmets, and early 1970’s rock. If there is an afterlife, I sure hope to avoid that part of it!

Society ...

I was working on a federal grant application yesterday regarding DNA analysis for criminal cases, and one of the Chiefs mentioned that the murder count to date for this year is 53. Last year on this date, it was 43. In 2006, we had the highest number of murders in ten years. And we’re on the way to break that record this year. So, things aren’t exactly going that well out in the post-industrial slums of Newark and its surrounding cities (Irvington, East Orange and Orange).

That bit of info made me reflect on my former life as a crypto-activist in Newark, i.e. my 2 years as a loyal volunteer and my 10 years of employment at New Community Corporation. New Community got started about 15 years before I got there, and reached its peak in terms of size and achievement during my tenure. But unfortunately, it never really got close to its lofty goal of “converting the neighborhood and then the city”, into a functional working-class environment where every child has a good chance of leading a fulfilling and productive life.

In fact, New Community unintentionally contributed to Newark’s ongoing urban tragedy by building and clustering thousands of low-income apartment units. These were designed to be humane, low-density alternatives to the many high-rise “New Jack City” towers that were built in the 50s by the Newark Housing Authority (and hundreds of other urban HA’s). But as unionized entry-level jobs left Newark in the 70’s and 80’s, and the schools fell apart in the 90’s, this housing served just as effectively as the old “projects” to breed a nasty way of thinking and an unpleasant way of life amidst those who couldn’t get out. New Community was imitated in its heyday by a variety of other Newark community agencies, who sprinkled thousands of additional low-income apartments throughout the town. Together with the extraordinarily large inventory of developments built by the Newark Housing Authority, large swaths of Newark have been “locked in” to poverty culture by these buildings for the foreseeable future.

And so, the gangs, guns, drugs and killings continue in greater Newark, despite valiant and innovative efforts on the part of both local police and my boss (the county prosecutor) to combat them. You could say that I’m now helping to mop up the mess that I helped to make. But please believe me, the road to this hell truly was paved with the best and most heavenly of intentions. I missed the formative days, when the spirit of Christian social justice at New Community was “so thick you could cut it with a knife”. However, the dream (and the illusion) had not fully died when I got involved with NCC in 1988. We still believed that we could disassemble urban poverty by weaving a thick net of housing, daycare, job training, youth programs and health services. We really didn’t anticipate that the surrounding economy and political culture would change so much; it happened while we weren’t watching. We couldn’t have imagined that as things got worse, an angry “f*** it” attitude would take hold amidst the young. Yea, this attitude sells plenty of rap music in the suburbs, but it ain’t no entertainment in the cities. Mopping up after the latest shooting is no fun, or so I hear from the guys at work who actually do that stuff.

Newark is not without hope. If you listen to Mayor Booker, there are plenty of things to be hopeful about in Newark these days (although Booker recently gave a rather despairing speech about the murder crisis). The downtown area is still getting better, a new professional sports arena will open soon, and thousands of new homes have been built and sold to valiant young families who are pushing the gang-bangers off their blocks. There’s nothing like owning property to inspire people to get involved in crimewatches. I even helped to develop about 300 or so of those houses during my final years at NCC. But there are still tens of thousands of impoverished single-parent families going from apartment to apartment (with boyfriends drifting in and out) throughout greater Newark. As welfare reform showed, the women usually find some kind of crappy, unpleasant work to keep their kids going. However, too many of the young men refuse to bite that bullet, and get caught up in the cycle of drug involvements, jail and gang affiliation. It’s nice that there are so many stable working families who are buying up all of the new houses, even on some of the worst streets. But the gang-bangers who they push off of those streets aren’t going to be going too far. No other towns will take them.

In my Some Urban Thoughts pages, I have outlined my vision for a new kind of urban anti-poverty effort (actually, a “regional” effort) to respond to the realities that let all the air out of my earlier idealism. But right now, I don’t see anyone with a new and more realistic vision making any waves in the cities and amidst the halls of power and wealth (as New Community’s founders once did). So, I’ll stay where I am, helping to mop up the mess that our spiritual justice inspirations ironically helped to create. But I still hope to live long enough to see a new spirit of urban activism, one that learns from our mistakes and builds on our failures. As I point out, it’s not going to be a bootstraps operation, as NCC tried to be. It’s going to directly involve suburban areas like where I live. That’s gonna be a tough sell. Still, you never know when a new generation of neophyte saints and prophets are going to come out of the woodwork. One must keep their hope alive.

Cultural Corner: I saw a little article about recent goings-on in the field of cultural anthropology. Actually, they’re doing some fairly interesting research these days. Well sure, anthropology was always sort of interesting, with Margaret Mead and her cronies searching out the last of the painted tribesmen and hunter-gatherers in central Africa or some far-away Pacific island, with their colorful feathered costumes and crazy dances.

But today, the anthropology professors and grad students are focusing on a topic that hits home, right here in post-industrial America. They are now doing “ethnography” research and writing papers about “commodity chains”. Consider this: in America today, it seems like we don’t make anything. Just about everything we eat, use, drive, burn, entertain ourselves with, etc. comes from somewhere else. The place could be Mexico, could be Brazil, could be China — who knows. Actually, there are people who DO know – they are the trans-national businesses that get rich off of all this international trade. And then there are the people in far off lands who dig up or make the stuff for those big importers. Interestingly enough, the anthropologists have recently gotten interested in all of this, and how it’s changing the world.

I hope that some of this research will be tapped by the popular article writers and TV news shows, to enlighten the public on just what the effect of modern trade arrangements are, and who wins and who loses. (No surprise that the losers are mostly the poor countries who gather the raw materials and process it for us; although maybe there are some good effects in some places). For the time being, I’m going to give links to a few commodity studies that I found in a quick Google search.

1.) Table Grapes from Mexico

2.) African Gray Parrots

3.) Imitation Crab (a.k.a. “surimi seafood”)

All of this stuff is probably exists right there in your home town, if not in your house; it’s available at your local supermarket and pet store, probably at the Wal-Mart. Maybe you might want to know a little about what the stuff is, who makes it, who brings it over and sells it, and whether things are better or worse off because of it.

Well, just thought you might want to know what’s going on.

I’ve been reading some books about human consciousness over the past two years (the serious ones, not the new-age stuff), and I’ve noticed that most of the authors don’t have much regard for God or religion. I suppose they figure it would be bad for their academic careers to mix metaphysical hope with such a strange and uncertain topic, as consciousness certainly is. The ones who posit that consciousness may be more than a materialistic process, at least beyond any material physics that we now know, seem especially assertive in asserting their atheism (e.g. John Searle, Colin McGinn, David Chalmers). Their “dualism” arguably leaves a gap through which God’s presence might arguably enter the world and be shared in and through our realization of it. But to even consider that possibility seems beyond the pale of any serious mind scholar right now. Even the most “science-friendly” concepts of dualism are attacked by many as naive, wishful thinking.

At least one consciousness researcher, Dr. Susan Blackmore from England, speculates that practitioners of Buddhist “mindfulness” find our conscious mind to be an illusory (Consciousness: An Introduction, 2004). Buddhists claim to know that the self and free will are illusions. They realize there to be no distinction between ego and experience. They experience nonduality. Well then, consciousness is certainly not real, and God is obviously toast too.

Right now I’m finishing a book by another ‘Dr. Susan’ from England, Dr. Susan Greenfield (The Private Life of the Brain, 2000). Dr. Greenfield makes an interesting point about meditation, the primary practice informing Buddhist metaphysics. Dr. Greenfield explains that the electrochemical processes which correspond to deep meditation create very large neuronal constellations which are remarkably stable and distributed, so as to deeply diminish the mind’s need for sensory stimulation. A different kind of consciousness ensues, one that is not in need of the usual external reassurances that we seek from our environments (the company of other people, conversation, music, food, etc.). At that rarefied point, the normal kind of egotistic self that we are used to becomes unnecessary. Thus, it becomes easier for those who have known such meditative experience to speak of how we don’t actually exist, how mind and earth are one, how nothing more is needed. It’s just an impression created by a certain mental state made possible by a certain combination of chemicals and electrical signals.

What I find interesting about this is how similar it is to the arguments being used by other mind analysts to disregard the opposite notion, that we are different from the earthy world beneath us, and that our difference is a half-way step to the ultimate principle represented in God. Daniel Dennett, Samuel Harris and Richard Dawkins have recently released books explaining those feelings to be nothing more than accidents stemming from certain chemical and electrical patterns in the brain, patterns that may have spun-off from useful evolutionary processes. Dr. Greenfield (who herself seems to have little sympathy for the religiously inclined) ironically identifies a similar pattern as the basis for non-belief.

So, it would appear that Dr. Blackmore’s fashionable Buddhist anti-dualism and its implied atheism are just as illusory and physically explainable as the processes which seem to push most people in this world, except Buddhists, toward the consideration of a “higher metaphysical principle”. (And a whole lot of Buddhists aren’t all that dismissive of higher metaphysical principles after all; the practice of Pure Land Buddhism, quite popular in Asia, has various elements that a Christian or Jew or Muslim would find familiar). Dr. Blackmore doesn’t seem satisfied with a dryly logical approach to the God-or-not question. She wants something a bit more deeply felt. But if so, then why would her Buddhist ‘anatta’ be any more compelling or intellectually respectable than my longing for ultimate universal hope?

It looks to me as if we wind up right on the fence, as always. The glass remains half-empty and half-full. It’s up to you what to call it. Despite the bad name that various political factions have given the notion of Abrahamic faith within the past few decades, I’ll stick with the hopeful view, but I’ll keep the ‘God-politics’ aside. And I hope that the consciousness analysts can likewise learn to disregard the politics and fashions of modern academia, and be able to think and write freely on whether or not their research leaves room for the notion of God. It would certainly be nice if discussions about God could be brought back to the intellectual circles without all the politically-correct fear.

Time for a picture. Here’s a shot I took on 5th Avenue in Manhattan, looking up at some buildings (including the Chrysler Building) on a sunny March afternoon.

I took a look at the New York Times bestsellers list the other day to see who is winning the day in the showdown between religious faith and “the new atheism” (which cites and interprets biological evidence to show that widespread human faith in a deity of one kind or another is just an evolutionary misfire). Right now, it looks as though faith is winning. Coming in at number 4 on the non-fiction hardcover list is “Grace Eventually” by Anne Lamott. Back at 13th place is “The God Delusion” by Richard Dawkins. Nothing too much after that, except down at number 29 there is “The Language of God: A Scientist Presents Evidence for Belief”, by Francis S. Collins (who made his name as a leader of one the two teams that fully mapped the human genome).

A spoiler, though, is Ayaan Hirsi Ali’s “Infidel”, coming in at number 5. Ms. Hirsi Ali was formerly a devout Muslim, and is now a pro-western atheist. But I’m not sure if I would count this book as a true commentary on faith. It may be more of a politicized reaction to politicized situation (i.e., radical Islam). God may have never had a chance in this case.

I noticed that the NY Times chose to review the Dawkins book and the Hirsi Ali book, but ignored the other two. I guess that the old-tyme religion just isn’t good enough for the Times anymore.

I have to take my hat off to Wired Magazine. I don’t have a subscription yet, but in doing internet research on a variety of topics, I’m often led to articles in Wired. If it’s about science or technology and its going to make a mark on the way we live, those Wired folk seem to be on it. Anyway, here’s a link to an article on “The Big Unanswered Questions”. Quite interesting. (No, I wasn’t paid to put this up. Just thought I’d give them a plug for making some good content available for free on the net.)

Another interesting magazine article: in the May Atlantic, there’s an article about homosexuality in Saudi Arabia. Actually, what I just said is not fully accurate. In fact, the article tells you about the many heterosexuals doing the homosexual thing in the desert kingdom. It sounds like what went on in the ancient Greco-Roman world, back in the time of the Bible; other than Mohammad and petrochemicals, things probably haven’t changed much in Arabia since then. So, if you want to know what St. Paul was ranting about with regard to same-sex perversions, read that article. More evidence that the anti-gay Bible thumpers are just plain wrong.

Brain / Mind ...

There’s an interesting little technology quirk coming over the hill called “transcranial magnetic stimulation” (TMS). I’ve read a few things about how neuroscientists are using it to study the brain. Basically, it shoots a pulsating electro-magnetic inductance field through your skull and into your gray matter, where it can mess around with the electrical signals flowing through your neurons. That’s the stuff that makes your mind work and forms your consciousness.

TMS has been around for some time now, but with all the brain research going on these days, it has been put to much use lately. Aside from brain function experiments, it is now being tested as a therapy for depression and migraine headaches. And one scientist, Dr. Michael Persinger in Canada, is using it to generate mystical states of consciousness, akin to religious experiences. He’s been rather successful at it. Other scientists think that it unlocks many different types of creative mind abilities.

So, the TMS technique is starting to sound like a drug, something that can have a profound effect on consciousness. And it’s not illegal. And furthermore, it’s not all that high-tech. It lends itself to an electrical handyman’s basement project. In fact, there’s a wiki web site for those interested in do-it-yourself TMS. It’s a bit uncertain what power levels are going to be needed to get results. Most TMS researchers use high-powered electromagnets outputting 1 to 1.5 Tesla of field strength for short bursts. That sort of machine would require at least 120 V power and some heavy capacitors. But Persinger’s research alleges that weak fields, down in the microtesla range, can have noticeable effects. That would be more in the battery or 12V converter range, where nobody could get badly hurt. Let’s hope that the Popular Science crowd and the new age electro-stoners stay away from the industrial equipment. If it can be done outside the lab, it can be abused, and someone’s gonna get hurt.

And there are indications that this technology can hurt as well as heal. If the pulses hit the wrong areas of the brain, there is the possibility of seizures, or interference with autonomic brain stem processes (like breathing and heartbeat). So yes, the military has become interested in TMS. At minimum, the University of South Carolina is working on a device to put in soldiers’ helmets that would counter the effects of exhaustion and sleeplessness. But there might also be negative effects that can be guided towards the enemy, as the technology develops. One can also imagine TMS as a future domestic homicide tool, if they can miniaturize the technology. A disgruntled spouse charges up his or her TMS-stun gun, then while the unfaithful partner is asleep, just a few zaps to the back of the neck, and . . . . no bullets, no poison, no blood, pretty much no evidence.

Well, I’m not in any hurry to fry my brain circuits with the equivalent of a nuclear electro-magnetic pulse (those of you who watch Jericho know what that can do). But then again, I can’t help but wonder if waving a magnet back and forth over the right ear might bring inner peace after all.

◊  BIRD BLOG
Nature ... Photo ...

A couple of weeks ago, I put a little bird feeder on my window, just above the air conditioner. It took a while, but the feeder is now quite popular amidst the local avian population. The regular customers include a flock of mourning doves, numerous house sparrows, some white-throated sparrows, a pair of cardinals, a blue jay (that barely seems able to balance itself on the air conditioner ledge), and an occasional visit from a tufted titmouse. I believe that the juncos that winter in the local backyards also stopped by, but with spring finally arriving, they are now headed back to the woods. There are occasional raids by bands of starlings (although we don’t have any that live nearby). The noticeable absentees are a pair of northern mockingbirds, and the local robins. Give those robins credit: they are purists. They stick to their worms and bugs. They don’t want to mess with grains and carbs; they stick with high-protein.

So it’s an interesting little nature show going on outside my window. It gets pretty wild some days; these little birdies like to fight over food. It’s every bird for him or herself. Even though I keep the feeder stocked, they have a hoarding mentality. Peck, peck, push, push, get out of my way. I’ve even seem little birds fighting while flapping their wings in mid-air. And the mourning doves . . . . they may seem meek and mellow, but I saw one stare down a blue jay, and win! It’s a bit depressing sometimes; but then again, it all makes me feel a little bit better about the human race. We don’t behave all that much better than these birdbrains, but we are still better (if not by much).

When all the bird aggression gets me down, I look for the cardinal pair. The bright red male has a habit of giving food from its beak to its brownish mate. No “wham, bam, thank you mam” for these guys, despite their stylish crimson plumage and black masks. They’re committed to a long-term relationship. They’re obviously gonna keep momma fed while she tends to the nest and the youngins’. Ah, family values.

Here are two shots of some mourning doves chowing down.
