With or without the Creationists, evolution continues apace

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

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

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.
