Hex Marks the Spot

1 Comment

Public versus private has been on my mind quite a bit lately. Partially it’s because I’ve been reading about magical beliefs and their persistence. It always amazes me how publicly we declare ourselves rational and uninfluenced by the supernatural. Once we get behind the closed doors of our domiciles, however, a transformation takes place. Our insecurities and uncertainties surface. Given the right circumstances we might even confess that we believe in magic. I know I’m generalizing here, but private space does allow for private thoughts and getting out with others can bring a much-needed relief. I was reading about Hex Hollow in an article a friend sent me from Roadtrippers. Hex Hollow is a small town in my native Pennsylvania where a murder took place over witchcraft. I won’t go into the details here—the Roadtripper story is quite brief and tells the tale—but it turns out a man was killed for being a witch. His murderer was also a witch who’d been sent to him by yet a third witch. The crime took place in 1928.

Think about the timeframe for a second. It was between the World Wars. Technology was fairly advanced. Witch trials had ended centuries ago. Still, some people believed enough in witches to kill for their conviction. Historians of religion have pointed out that Americans have never really outgrown the belief in magic that we deny so assiduously. I’m not trying to single out one nation here—there is widespread evidence that magical thinking is endemic to the human thought process. We aren’t so quick to let something go that, according to reason, has served us well. Had magical thinking been purely detrimental it should’ve died out long ago. We need our magic.

As yesterday, so today.

I’m not suggesting witchcraft is real. At the same time I know that it’s natural enough for thoughts to move into familiar terrain when stressed out. In Hex Hollow the man who did the murdering was convinced he’d been hexed by his victim. Perhaps he’d climbed the ladder of inference (what we tend to call confirmation bias) to a rung where the only way down was a criminal act of desperation. That’s no excuse to kill someone, of course, but it fits with what we know of an all-too-human form of stress relief. Nor is it rustic rubes to blame. Psychics in New York City are abundant and even US presidents have been known to consult the stars a time or two. Of course, once I step outside that door I’ll say it’s all nonsense.

Human Omniscience

This might take some thought, but please bear with me. I’ve been reading about how some scientists are eager to promote rationality only as the true understanding of the universe. The flaws in this logic are immense. The greatest gaff here is assuming that evolved biological creatures with only five senses have come to comprehend the vastness of a universe in which we matter very, very, very, (and some scientific notation may be helpful here) very little. And we assume that’s all there is to know. Consider that when you want to spot the Pleiades in the nighttime sky, the best way to do it is not to look directly at the constellation. Our rods, which are far more sensitive than our cones, are not concentrated in the center of our field of vision. That means, in some circumstances, you see something better by looking slightly away from it. Don’t take my word for it, test it yourself on a clear night.

We also know that some animals have senses that we don’t. When’s the last time you picked up the earth’s magnetic field? We know it’s there and we know that some animals sense it. We don’t. Or consider the ant. If ants make you itchy, any hive mind will do. There are creatures right here on earth that think collectively, not as individuals. As humans we’ve evolved to think that our limited experience tells us everything there possibly is to know about truth. We don’t know how living under water influences perceptions because we can’t do it. No, we’re a race of surface dwellers. (There’s a metaphor there for those of you who believe in such things.) We’ve learned some basic laws of physics and suddenly we preside over the courtroom of the universe since our evolved logic is the only and the best the cosmos has to offer.

Evolution, however, also made us religious. If logic is at all what it seems we have to admit that study after study has shown the benefits of religious belief to the beleaguered human psyche. If we try to measure it empirically it crumbles in our fingers. Only logic would tell us simply to ignore it then. I’m no enemy of reason. It’s the best way we have of getting along in this world. I love science and support its evidence-based health. It’s just that as I’m standing here in the dark wondering where the seven sisters are, I sometimes have to trust my rods instead of focusing on what I can see plainly with my everyday sight. Logic tells me there are other things outside my sensory range as well.

Spiritual Spelunking

1 Comment

Looking at the headlines it’s sometimes difficult to believe we’ve evolved. I still trust evidence-based science, despite official government policy, however. So when a friend sent me a story about a new human cousin I knew it was worth a look. Homo naledi bones date from much more recent times than they should. At less than 400,000 years old (which means they might fit GOP ideology pretty well) they are almost contemporary with Homo sapiens. And, apparently, they buried their dead. Now much of this is still speculation. The bones were found in caves with openings so small that onlyfemale spelunkers could fit in, and the question of whether dropping bodies in a hole counts as burial has raised its head. Still, the human family tree is being redrawn, and in a way conservatives won’t like.

I became interested in evolution because of Genesis. My mother gave us a few science books as children even though we were Fundamentalists. One of them talked about evolution and I was intrigued. Clearly it didn’t fit with the creation story—I was young enough not to notice the contradictions between Genesis 1 and Genesis 2—and yet scientist believed it. They likely weren’t Christians, I reasoned. College gave the lie to that deductive thinking when I ran into Christians teaching the required “Science Key” who believed in, and yes, taught, evolution. I’d missed something, obviously. Once I discovered evolution could coexist with Scripture I was eager to learn as much as a non-biologist could. In my teaching days I focused on the early part of Genesis and even began to write a book on it.

It’s much more honest to admit that we’re related to the rest of life on this planet than to set ourselves aside as something special. Evolution has done something that the Bible never could—brought all living things together. There are too many towers of Babel and chosen people themes in Holy Writ to allow for real parity with our fellow humans, let alone other creatures. Yet the human family tree is wondrous in its diversity and complexity. We now know that Neanderthals were likely interbreeding with Homo sapiens and I wonder how that impacts myths of divine chosen species. Did Jesus die for the Neanderthals too, or just our own sapiens sapiens subspecies? You can see the problem. For a literalist it’s just easier to crawl into a cave. But only if the opening is large enough to admit males, since the Bible says they were created first, right?

Science Marches On

A few thoughts about the March for Science in Manhattan over the weekend seem to be in order. To get to the rally in time, from our little corner of New Jersey, we found ourselves on an early train. We arrived at 62nd Street and Central Park West to discover the march was beginning just outside of one of Trump’s unimpressive towers. The area for marchers was clearly marked off by barricades, but a woman walking her dogs, a resident of Trump’s tower, wandered in among the crowd. Like most Trump followers, she seemed clueless that there was an obvious way around the obstacles and had to be helped by the police. Seems to be a theme with 45—police are everywhere watching his assets. Meanwhile the hotel doormen from next door were asking for “Resist” paraphernalia and reminiscing about their shock when the boy next door received the nomination. The mood was jovial despite the spitting rain.

The speeches at the rally were mostly given by children ten and younger. The future teaching the past. As might be expected, the signs were clever, and some took considerable thought to figure out. A few, it seems, felt religion was to blame. Well, they’re probably right about that. One gets the sense that science and religion are like cats and dogs, and nobody has to guess which one’s identified with the cats. Still, the majority of the signs pointed out the benefits of science. Even scholars of religion use the scientific method, believe it or not. Like science, religion (as revealed by science) may be good for people. Who brings religion to a science rally?

I’ve always been a fan of science. Throughout school I learned a lot and did well in physics and chemistry, biology not so much (dissection was never my thing). I still read science and incorporate it into my thinking. Balance, however, suggests perhaps religion also be treated as not evil in and of itself. After all, it is evolved behavior. As the march progressed down Broadway, we passed a church that had a prominent banner reading “Prayer really does work,” or something along those lines. I’d seen enough clever signs already that morning to notice this contrarian voice. Then I wondered, why can’t science and religion seem to get along? Both can (but need not) make exclusive truth claims. What’s wrong with admitting that we just don’t know? Belief is involved in either case. No doubt science is important. I’ve always supported its study and always will. Is it, however, too much to believe that maybe religion can also enlighten, if understood for what it is—a human way of coping with an uncertain world? As science marches on, hopefully it will help us comprehend even the unmeasurable.

Palms and Thorns

“Holy Week” affects only some. That thought may be disturbing to those who still think of religions as a one-size-fits-all phenomenon. So, although today is Palm Sunday for many, for others it’s just Sunday. Not even all Christians recognize the same Palm Sunday. The question that interests me, though, is the one regarding which religion is the right one. I personally suspect this is the behind the rise of the Nones, but I’m getting ahead of my story. How did we come to this impasse? How did we come to believe that only one winner takes it all, spiritually speaking? The answer may lie in evolution.

I don’t mean biological evolution. Borrowing a principal for how this factual occurrence works, however, may help to understand the diversity of religions. For species to differentiate, they must be isolated from each other somehow. Groups that are available for interbreeding will do precisely that. When populations are separated, subtle changes add up over the passage of time so that when they come together down the road mating’s simply an impossibility. Religions behave the same way. The difference, apart from biology, is that many religions allow multiple gods. They aren’t so different from each other. In fact, we’re not even sure if gods are sufficient to define “religion.” People from diverse cultures in ancient times, the evidence seems to indicate, tried to match up their gods. Your Zeus is our Odin kind of thing. Monotheism—the main form of religion that has a problem with evolution—is the ultimate exceptionalist belief system. Our one deity is the only deity and everybody else is wrong. When populations come together we can’t even agree that the God who’s historically the same is in reality the same. Ours is slightly better.

Amid all the chaos created by religions, academics have decided they’re a phenomenon not worth studying. Academics often lose sight of the larger picture. What happens outside the classroom or laboratory is real life too. And outside the walls of the ivory tower the faithful are gathering. Some today are doing it with palm branches in hand. Others are looking on, bemused. The important thing is we don’t talk about it because talking might lead to understanding. And understanding might make us concede that others have some good points to make with their religion as well. How can you feel special in the eyes of your own god when other people suggest other truths might also apply? No wonder someone will end up crucified by the end of the week.

All There Is To Know

I’m sorry, I didn’t mean to be rude but I just had to laugh. A friend sent me an article from Science Alert titled “A Physicist Just Explained Why the Large Hadron Collider Disproves the Existence of Ghosts.” Intrigued, I read, “there’s no room in the Standard Model of Physics for a substance or medium that can carry on our information after death, and yet go undetected in the Large Hadron Collider.” One of the reasons, I believe, science has trouble among hoi polloi is such arrogant statements as this. I don’t know about ghosts, and for a very good reason. There is no experimental way to test for that which doesn’t exist in the material world. The LHC may tell us all we can know about the world that we perceive (although I doubt it) but it can’t tell us about that for which there is no measure (e.g., consciousness). I don’t mean to get all complex here, but let’s stop and think about this for a moment.

What we know of the universe is what we can perceive and extrapolate from that perception by reason. We, however, don’t perceive everything. Our five senses evolved for one purpose and one purpose only—to survive in this particular environment. That’s a trait, hate to admit it as much as we might, that we share with other animals. It helps to be able to see, hear, touch, taste, and smell things clearly. These traits give us valuable information about the world around us—is that plant poisonous? Is this heat going to kill me? Should I avoid approaching that large, angry-looking bear? Things like that. What our senses don’t tell us is the aspects we didn’t evolve to perceive. We understand everything about nothing. Put another way there is nothing that we understand completely. Entire books can be written about the concept of zero and that’s just an abstract. We only experience a small piece of this universe.

That’s the problem with being in the backwater of the galaxy. I grew up in a backwater so I know what I’m talking about. Things might be different if we lived near the galactic hub, where beings with different senses may well exist. We know, for example, that even on our planet some animals perceive magnetic fields. Who knows what kinds of abilities might have evolved on worlds that posed different challenges to survival than our own? Who are we to say that here in our basement on earth we have a machine that can uncover every possible permutation of anything in the known universe? I don’t know about ghosts, but, I suspect, they’re laughing too.

Saint Charles

Honestly, I’m not sure where the idea of votive candles started. An educated guess—which will have to do in my state of limited research time—is that candles, like oil lamps, began as a practical necessity in places of worship. Temples, churches, synagogues, mosques—these tended to be large rooms and sometimes featured stained glass in their windows. Even if they didn’t, sometimes people want to pray after dark. Especially after dark. In the days before electricity, a lamp or candle was an obvious choice. Over time the practice of lighting votive candles developed. Lighting a candle for someone, living or dead, symbolized saying a prayer for them. The idea is much more common in liturgical branches of Christianity than it is in strongly reformed ones. Still, it’s a comforting idea. The few times that I’ve lit a candle for someone I’ve always felt better for having done so.

Whenever a practice becomes sacred, parody is shortly to follow. As human beings we seem to be inherently aware that we take ourselves far too seriously far too much of the time. When I go to the grocery store—usually in the aisle with the more “Catholic” ethnic foods—I glance at the large, painted votives for sale. Secretly I’m hoping I might spot one for Santa Muerte, but this far north and east of the border that’s unlikely. Our own version of Saint Death is about to take office anyway. I was pleasantly surprised, therefore, to find a Charles Darwin votive candle in my stocking this past month. Intended, of course, as a novelty, there’s nevertheless something a bit profound here. What we’re praying for is the continuity of life. Evolution itself is under threat of post-truth science which is soon to receive official sponsorship. Time to light a candle and hope for the best.

I plan to keep my Darwin candle for emergencies. The idea isn’t that the figure on the candle is a deity. Those painted on the candle are the saints who have some influence in the divine hierarchy of this cold universe. When you light a candle you ask that saint to witness your prayer. I sense that many among my own political party have recently rediscovered how to pray. The beauty of a Darwin votive is that it’s non-denominational. We all evolve, whether we admit it or not. So if you can’t get yourself to a church, synagogue, or mosque on the traditional day of worship, Darwin can shed light at any time. And maybe even support a prayer for light in the coming darkness.

What Democrats Don’t Understand

2 Comments

Human evolution (while it still legally exists) tells us a considerable amount about belief. Brain science (while we still have it) has long indicated that our noggins evolved to help us survive, not “to figure out” the world. Along its long and torturous path to modernity, the human brain has developed the ability to believe what it knows not to be true. This doesn’t just apply to the study of religions, but, in reality, primarily to psychology. Patients with split brains have shown a mastery of rationalization that should make any Republican jealous. So far the Dems are with me. What Democrats don’t understand is that you can’t change beliefs with reason. I grew up a Fundamentalist. That past still continually haunts me. What brought me out of it wasn’t thinking. It was experiencing. Specifically, experiencing in the course of education.

Recent polls show that well over 50 percent of Republicans believe Trump won the popular vote as well as the electoral vote. You could show this 50 percent as many statistics as you like and you won’t be able to convince them. Belief doesn’t work that way. In my experience, higher education (typically characterized as liberal) doesn’t really care about understanding belief. They hire professors recommended by establishment friends, very much like cabinet posts are now being filled. They still believe if you talk at someone long enough with reason, they will change their minds. I can’t change that belief of theirs—I have an idea how belief functions. We’ve all seen how the system works. Not every 1930s German was a Nazi.

In other words, it is very easy to believe a lie is the truth. In the words of Jim Steinman, “everything’s a lie and that’s a fact.” Education may help you spot the contradiction there, but it won’t help you unbelieve it. The truth is power can’t be taken, it must be given. If people do not believe what the media tells them, it isn’t true. As someone who’s spend a half-century trying to figure this out, I’m always amazed that my own party can’t see what’s so obvious to a reformed Fundamentalist. Until the day comes when avowed rationalists admit that emotions matter just as much as orthodox reason we will all be at a loss to explain how otherwise intelligent people will insist that what they know to be lies are indeed the truth.

Possessed by Work

Leave a comment

Now that I’m safely ensconced back in the daily work routine, I spend some time thinking of the scary movies I had time to watch during my “free time.” Well, I actually thought about them then, too, but I had so many other thoughts to write about that I kept putting it off. That, and the fact that some of the movies were about demonic possession and the juxtaposition of holidays and demons just didn’t seem to fit, kept me from expounding. Why watch such movies at all? It’s a fair question. I tend to think of it as part of a larger thought experiment—wondering what such movies might tell us about being human.

stanthony

A few weeks back I wrote about The Exorcism of Emily Rose, based on the true tragic story of a young woman who died after a prolonged exorcism. After that I watched The Last Exorcism, The Rite, and The Possession. (I’m such a cheerful guy, as you can see, and this may be why I inhabit an isolated cubicle at work.) This array of movies, held together by the common chord of the reality of demonic possession, also brought together the standard sociological division of Protestant, Catholic, and Jew. The Last Exorcism is a Protestant-based treatment of what is generally considered to be a Catholic subject. That connection is affirmed in The Rite. The Possession, however, gives us a Jewish demon and a rare representation of a Jewish exorcism (acted by Matisyahu, no less!). What emerges from watching all of these films together is that demons are an inter-denominational problem, even in a scientific world. Carl Sagan wrote about the demon-haunted world, and it continues to exist, it seems.

But these are movies we’re talking about. Not reality. Nevertheless, The Rite and The Possession are also said to be based on true stories. We do live in a mysterious world. Evolution has developed reasoning as a practical way of dealing with life in a complex ecosystem. It is a survival mechanism. So is emotion. We sometimes forget that both thought and feeling are necessary for survival in our corner of the universe. Neither one is an end in itself. We can’t quite figure out how these two features of the human brain work together. There are, in other words, some dark corners left in our psyches. I suspect that’s why I find such movies so interesting. They’re not my favorites, but they do serve to remind us of just how little we know. And that’s a scary thought, given how we’ve learned to possess this planet.

Surfeit of Ego

Leave a comment

img_3098

In a world with finite resources, many commodities are in short supply. One clear overabundance is that of ego. We’ve seen that clearly in the long, long months of this year’s political campaign and the single month since then. Running a nation is no longer to be a servant to the people but to the self. So it was while out on an errand I noticed a tract stuck in my car door handle. I’ve mentioned Tony Alamo before. This incarcerated evangelist has a disturbing number of supporters in New York City, at least to go by how prevalent his flyers are in Midtown. I’d never, in my suburban Jersey neighborhood, had my car violated by one before, so this was something new. What caught my eye was the grammatically inept headline: “Bill Clinton, The Pope, and I.” As a title it should have said “and Me.” Letting that foible pass, we’re still left with a religious zealot classifying himself with duly elected world leaders.

I know that the Roman Catholic Church is not a democracy, by the way. Popes, however, are elected from among their peers, and so it’s not purely a matter of one man putting himself forward as the people’s choice. Alamo’s headline screams of a wounded ego. Donald Trump’s famously thin skin does the same. Not that that makes me for one second sympathetic. I grew up with a religion that taught self-denial, self-abnegation, and putting others before oneself. Self, self, self. Selfishness used to be a sign of poor manners or bad breeding. Now it’s the way to the highest political office in the land. We clearly have a surfeit of ego. The same is true for the terrible plague of racism and sexism that have become the flavor of the day. Too much concern with self.

Not only is this a political aberration, it also goes against human nature. In the literal sense. Our species has thrived because of its sympathy for others. We see this is primate societies. When one individual, even—or especially—an alpha male, asserts himself beyond the good of the group, he is taken down. In addition to our opposable thumbs, we’re also endowed with a sense of fairness, of sharing. Call it the ethics of nature. Not only that, but most religions agree—the sign of a just society is one where everyone is cared for. So it may be that we don’t have enough coltan to make all the smart phones we need but we do have enough ego at the top to go around, and then some. Might I suggest it might be time for a fire sale?

Fictional Fact

Leave a comment

Do you remember that tragic sinking of a Staten Island ferry when a giant octopus pulled it under? Sounds vaguely familiar, but I wasn’t living near New York at the time. A story in The Guardian tells how Joseph Reginella, a sculptor, made his commemorative piece of art for Battery Park for a fictional incident. Like the memorial for War of the Worlds in Grover’s Mill, New Jersey, this is something we remember that never really transpired. We remember what never happened. It’s easy to forget that memory evolved for specific purposes. Mainly we remember for survival. Our brains evolved to keep us alive. If we don’t recall where we found water, or where that hidden cliff edge is, we don’t last for long. But we remember other things as well. The time that Oog borrowed your stone axe and didn’t give it back. Our social memory made us human, so we’re told.

No doubt it is possible to develop a keen memory. Precise recollection of events just as they happened, in sequence. It’s also possible, even collectively, to misremember things. We tell stories. We make myths. There was no giant octopus incident. Maybe we saw such a thing in a movie one time. That movie, paired with the plausible evidence of a public monument commemorating the event becomes a modified reality. I’m just sure I can remember it happening, can’t you?

Studies of such phenomena tell us that memories aren’t what they seem to be. To make distant recollections Holy Writ, for example, we have to rely on divine inspiration. Without it we might just be remembering a story somebody told once upon a time. And where did I put the car keys? Yes, our memories are open to manipulation. Things that never happened become real this way. George Washington did not chop down a cherry tree and confess to his father because he could not lie. And yet we believe. We make myths because they give our lives meaning. Face it, evolution is a pretty boring explanation for why we’re here. Natural selection has no goals in mind. Things that work best tend to survive in the gene pool. And in some people’s memory there may be a giant octopus in that pool as well. Did the the Cornelius G. Kolff get pulled under or not? Would a ship with such a name ever be made up? Myths are still born every day, even as the octopuses cower in their caves, awaiting the next naive ferry to transcend reality.

The Science of Being Human

2 Comments

Not so long ago, when I was still a professor, a colleague told me he had no interest in science. We studied religion, he reasoned, and science had little to add. I was in the midst of a research project at the time. That project was exploring how what we know of evolution (or knew at the time) might inform our understanding of ancient texts. Of course, I was working in relative isolation, noting in my cover letters to universities that my research would benefit from an institution with a cooperative and collegial atmosphere between the sciences and humanities. If you’ve read this blog before, you know how that ended. No cooperative schools ever thought such research was worth sponsoring. After all, there are younger, less expensive specialists out there examining ancient religions in microscopic detail. The rest of the world, of course, wonders why.

This divide, as so eloquently delineated by Marcelo Gleiser in a piece on NPR, is starting to grow narrower. Science is taking us, in many fields, very close to the humanities. And we can’t make sense of some of it without admitting our human limitations. This is what I so admire about Gleiser’s writing—he is a scientist who understands that arrogance has no place in intellectual inquiry. Biology, as I long ago expected, holds one of the keys of this dilemma. Our brains evolved for a specific purpose—to help us survive in a predatory world. They did not evolve into processing systems to comprehend, as one sage put it, life, the universe, and everything. No one brain can hold all that knowledge. Like it or not, that brain in human. And humans need humanities.

Some scholars among the humanities like to claim that science has reached too far. The problem is, any scholar who is a true scholar is also a scientist. We use scientific methods to understand our admittedly speculative, or at least subjective, subject matter. Science isn’t the enemy here. Arrogance is. As Gleiser has stated in other venues, we have to approach the world with humility. We know so very little. Part of that world is that beyond human reach, and part of that world is what humans have done. They’re both part of the larger picture. But humans live on a small planet that we now know is only one of many, many more throughout the visible universe. And we know the visible universe is only part of the story. But we can’t be honest if we forget that the minds trying to understand all this are, no matter how evolved, only human.

Bad Theology

Leave a comment

train_wreck_at_montparnasse_1895

Perhaps the most overused simile for a real mess is that it’s “like a train wreck.” No doubt this is because train wrecks are messy, and deadly. Few things speak to human vulnerability more than airborne hunks of heavy metal flying in indeterminate directions. Trains don’t stop fast. If they do people get hurt. No, I wasn’t on the train that crashed into the Hoboken station yesterday during the morning commute. I’m just one of many thousands of people who make their way into the city every day, but I go by bus, which is more affordable. Still, there’s something in every commuter that mourns a tragedy like this. We’re not in competition for getting into New York. It’s only after we’re off our conveyances that we compete. The stories after the crash, however, emphasized something I’ve always known—people are basically good.

A strain of Christian theology makes the extremely dubious claim that people are “totally depraved.” Assaulted again and again with this misanthropic theology in college, I was bound to fight back. Some guys with minimal psychological training decided, in the early modern period, that God had created the vast majority of people for Hell. Because we share the primates’ evolved taste for fruit, we participated in “original sin.” It wasn’t exactly sex (since God had declared that good) but it was a consequence of it. We were born fallen and had to be redeemed. These theologians declared, however, that very few ever would be. Most of us were Hell-fodder and deserved to be since we’re so naturally evil. A few centuries earlier Jesus had said you’d know the righteous by their fruits. There’s no getting away from the fruit.

Life in the big city is impersonal. Commuters share their conveyances each day with many strangers. After the wreck, however, as my wife pointed out, those in the cars far enough back that the injuries weren’t grievous first turned to everyone else and asked if they were all right. If they need help. If they could walk. Strangers helping one another. Good Samaritans. It doesn’t sound like total depravity to me.

Our economic system thrives on hyped-up competition. When we’re taken out of that context and placed into a human one, we cooperate. We want to help one another. Perhaps it’s not the people who are totally depraved, but the system they’re forced into. No, I wasn’t on that train. My bus had pulled into New York an hour and a half earlier. But even from a distance I could see what I’ve known all along. People are basically good.

News from around the Universe

Leave a comment

In the last couple of weeks two large-scale news items caught my attention. One describes how a newly discovered galaxy is made up of mostly dark matter. The other tells how a new fossil find in Greenland may push the origins of life on earth back to 3.7 billion years ago. If you read my blog, you know that I’m a frustrated scientist. I’ve always tried to follow the developments in the field and even considered it as a profession until I ran into the wall of mathematics. Ran into the wall, banged up the car beyond repair, and was barely able to walk away. That’s the breaks in a world where ambition and ability aren’t the same thing. So I have to take my science like baby-food, mashed and strained before it makes its way to my brain. I know I’m not alone in this—the whole field of “humanities” proves that. (Originally science (astronomy) was one of the humanities, but oh how we’ve grown!)

Into the storm

Such frightening things as mathematics aside, these are exciting stories. I’ve been looking around this galaxy quite a bit, and I can believe dark matter outweighs light matter and I’ve never even been off the earth. The story is encouraging because it shows just how much we have yet to learn. Nothing could be more exciting for an erstwhile educator. The opportunity to stretch one’s mind should never be taken lightly. At the same time as dark matter is growing, so is the age of life on earth. I have to admit that I’ve not even been to Greenland, but the idea that life began so soon after the earth formed has cosmic implications. If we were such fast starters, doesn’t that suggest that elsewhere in the universe the same may be true? Ironically, here on earth uniformitarianism is considered a foundation of science. But once you get off earth scientists are reluctant to say the same processes could have happened elsewhere. But what do I know? I’m still trying to figure out trigonometry.

Earthbound I may be. Humble humanities specialist from start to finish. Nevertheless it is an amazing time to be alive. Once we’ve figured out that human brains—products of evolution that they are—aren’t capable of ultimate comprehension, we’ll be able to bask in the light of billions and billions of suns and raise a glass with our cosmic neighbors, made of light matter or dark, and proudly say that we’ve made some real advances at last.

ImprobablePrimateEnvy is not a word I would use to describe how I feel about those trying to piece together the earliest stages of humanity. Evolution, naturally, is a given. Once beyond that, however, the landscape gets dicey. Clive Finlayson is an author I don’t envy. I just finished his The Improbable Primate: How Water Shaped Human Evolution, and it felt like he had to put this immense puzzle together while missing about nine-tenths of the pieces. Early human fossils are rare and it doesn’t take much to throw a laboriously constructed scenario into yesterday’s mistaken hypothesis bin. The central premise of the book, as stated already in the subtitle—human evolution followed water—seems about as firm as any idea. We need water daily and our bodies evolved to help find it efficiently. It’s a fascinating story. Along the way I learned that much of what I’d previously learned about ancient human development was probably wrong. I’m only a casual evolutionist.

Finlayson suggests—and not all biologists would agree with him—that all humans living on earth at any one time (with one possible exception) were of the same species. That is to say, the model I grew up with of separate species (Neanderthal and Cro-Magnon were the usual suspects) duking it out over scarce resources doesn’t match growing evidence very well. We Homo sapiens seem to share some Neanderthal DNA and that paints a somewhat more romantic encounter between the species than the violent one I learned. The same goes for other human ancestors, according to this little book. Our first instinct may not be to kill the stranger. We may have lived apart for a few thousand years, but when populations come back together they “share genes,” if you get my drift. This still happens, of course. The difference is today we’ve become politicized and entitled. We don’t want people not from around here to share our stuff.

Part of that is natural, I suppose. Finlayson points out that the feeling of belonging in natal territory is something we share with other primates. We feel that we belong where we’re born. That seems to me a difficult thing to quantify, but I feel it nevertheless every time I venture back to my hometown. It just feels right. Not that we can’t adjust to elsewhere, but our nature rewards us, in some measure, when we come home. This is a wide-ranging study for such a small book. I don’t envy all the meticulous jigsaw staring without a box-top that students of human origins must do, but the results are still quite interesting. Even if the picture, when enough pieces are finally found, ends up being something different than we thought it was.
