The Thinking, Walking Biped, part one. Pascal Picq and Human Evolution

This essay begins a series about the importance of walking in human evolution and history.

Cogito, ergo sum, said Pascal, or someone. I think, therefore I am. In French it would be je pense, donc je suis. But one French writer, an anthropologist named Pascal Picq, has changed this a little. He says, je marche, donc je pense. I walk, therefore I think. He has made the case that we are not just bipeds who think, but we think because we are bipeds. He attributes the evolution of human intelligence not just to the fact we are bipeds, but because we are bipeds who can walk and run for long distances, with outstanding endurance not found in other mammal species. Maybe this is obvious to you, but I’d never thought of it until I read Picq’s book La Marche.

Picq overviewed the history of scientific explanations for why humans walk upright. This has always been somewhat of an enigma. Quadrupeds can run a lot faster than we can. Anthropologists have come up with all kinds of advantages that bipedalism conferred on our ancestors, such as being able to look out over the vegetation to see either danger or opportunity, or to use our forelegs as arms that can carry things such as food and kids and weapons. Long distance migration is what evolution has favored in our species: even old people can walk long distances unless they have health problems or are injured (I do it nearly every day), and there are a lot more elderly marathon runners than elderly speed sprinters.

While these things are all true, Picq has added another: bipedalism has altered the evolution of our minds. Bipedalism (as in Australopithecus) preceded intelligence (as in Homo), and here are some reasons why.

Humans are superb wanderers and have been so throughout our evolutionary history. National Geographic writer Paul Salopek is retracing, on foot, the epic journey of humankind from our African genesis to the end of the journey in South America. Other mammals run faster, but do not migrate as far as humans have. Starting about a hundred thousand years ago, prehistoric humans spread from Africa to every continent except Antarctica. These migrations set up an advantage for intelligence, because our ancestors had to decide whether to migrate (that is, is migration worth the cost of leaving home), and then how to get someplace and know that the new place was where we wanted to stay. This required superb observation and memory of the environment and ability to analyze opportunities. This was true on the short scale (we want to go this way, but there is a river, and we have to figure out how to cross it, which may involve turning around and going back the way we came) and the long scale (we want to get to that hill, from which we can see into the distance and plan what to do next, if anything). Homo sapiens was apparently better than this than Homo neanderthalensis. Our intelligent ancestors also had to think ahead about, and remember, the migration routes and habits of their prey. Neanderthals killed mastodons; humans planned ahead about where the mastodons would be before trying to kill them.

In all these ways, our thinking evolved as a series of logical steps. That is, it required reasoning ability. A primitive (or modern) philosopher or scientist will try out ideas to see if they work, then come up with a backup plan if it doesn’t. This, Picq speculates, uses a similar mental network to figuring out where to go and how to get there on foot.

On top of all that, walking and running makes us feel good and releases us from stress. Picq said he got some of his best ideas while walking. I have the same experience. And perhaps the best example is Charles Darwin, whose “walking path” at Down House was where he got, and perfected, his major ideas. He did not get them sitting at his desk. Many famous composers, as well as other scholars, carried writing equipment with them. I have heard that Beethoven and Dvořák wrote musical ideas as they walked (see a later essay on this topic). Today, we have cell phones on which the thinking walker can record ideas.

All of this appeared on my science blog. I might also speculate that the origin of religion is partly influenced by walking. Our ancestors might have come up with religious explanations of the origin and purpose of things they saw and thought about along the way. And if they headed toward a distant mountain, this might make them wonder if they were headed toward a distant heaven as well. We walk by faith, and not by sight, the Bible says.

According to Picq, what science and philosophy needs more of is people who walk and think, rather than sit at desks and read what other people have written.

Stars in the Daytime: Stories of Disruption, by Stan Rice, story 8. Ursa Minor

Author Stan Rice has just published another collection of short stories: Stars in the Daytime: Stories of Disruption. Stan Rice is better known as a science writer, and scientific content and themes show up in most of his stories, including those in this collection.

Here is the author’s summary from Amazon: “You cannot see stars in the daytime, but they, like hidden reality, are always there. In these nine stories, Stan Rice asks, what if God appeared in the sky, with a message for Muslims? Can a theme park haunted castle help a young woman escape from genocide? What if an old greenhouse is the site of shifting timelines? What if a hotel burglar is actually a kindly man? What if a man discovers his girlfriend thinks of him as a teddy bear, then needs him? What happens if a demon from hell changes places with a human being on Earth? In one of the stories, Ruth meets Carmen.”

 

The stories in this collection are: When Pigs Fly; The Haunted Castle; Bleeding Earth, The Book of Ruth, The Lord Will Provide: Two Stories of Faith (all reviewed earlier); The Old Burrill House (reviewed in my science blog (url); The Gentleman (not reviewed in my blogs); Ursa Minor (reviewed here); and You Little Demon (reviewed in the last essay in this series).

In Ursa Minor, Rice explores friendship vs. sexual love. The unnamed main character is helplessly dependent on the sexuality of his girlfriend, who acts as if she does not need him. Then he meets Ursa Minor, an old man, who is far less fortunate in love and life than he is, but seems to accept it. To the main character, Ursa is like a teddy bear (which is what ursa minor means), but then realizes that he himself is a teddy bear for the woman he adores. When she becomes terminally ill, they both realize that the teddy-bear kind of love, humble friendship, is more important than sex.

Stars in the Daytime: Stories of Disruption, by Stan Rice, story 6. The Lord Will Provide

Author Stan Rice has just published another collection of short stories: Stars in the Daytime: Stories of Disruption. Stan Rice is better known as a science writer, and scientific content and themes show up in most of his stories, including those in this collection.

Here is the author’s summary from Amazon: “You cannot see stars in the daytime, but they, like hidden reality, are always there.

What happens if a demon from hell changes places with a human being on Earth? In one of the stories, Ruth meets Carmen.”

 

The stories in this collection are: When Pigs Fly; The Haunted Castle; Bleeding Earth, The Book of Ruth (all reviewed earlier); The Old Burrill House (reviewed in my science blog); The Lord Will Provide: Two Stories of Faith (reviewed here); The Gentleman; Ursa Minor; and You Little Demon (reviewed in later essays).

This story is actually two stories of faith gone wrong. In the first, a crazy religious man gives all his family’s money to a holy-roller preacher. But the man’s wife comes to the preacher to ask for the money back because her sick son will not survive without it. Even though to the preacher the highest form of religious experience is speaking in tongues, he realizes that mercy is more important than religious signs. In the appendix of the book, Rice explains that this story is true: the crazy man was his grandfather, and the sick child his father.

In the second story, a small fundamentalist congregation consists of just two people: an old man and his wife. The Bible forbids women to have any role in church other than to sing songs selected by the men, that is, the husband. The wife finally gets enough of it and leaves the church. In the appendix of the book, Rice says that this, also, is a true story.

These stories get inside the crazy mindset of fundamentalists. The old man would not attend any church that did not have what he considered a completely Biblical doctrine, and, after his wife left, was willing to drive fifty miles to the next nearest congregation of The True Church. His wife, meanwhile, just went around the corner to another church which was, as far as she could tell, just as good.

This is a story right out of the Bible, about which Rice, who has written extensively about religion, knows a great deal. Ruth is a Moabitess woman. Moab is one of the tribes neighboring Israel, which considers itself God’s chosen people. She is the friend of Naomi the Jewish woman. They live as gleaners, by gathering the grains dropped on the ground after the harvesters have passed through the grain fields. Ruth is extremely worldly, while Naomi is very religious. Actually, this story is not straight out of the Bible, but is what happens when Ruth intersects with Bizet’s operatic character Carmen. Ruth knows what she wants and how to get it.

A religious wanderer, Mahlon, sees Ruth and falls in love with her. Ruth wants Mahlon to fight for her; when he hesitates, she sings Carmen’s song from the opera. When a violent farm worker threatens Ruth, Mahlon quickly defends her. The rich land owner, Boaz, drives Mahlon away and decides to protect both women by giving them work within his house. He then marries both of them. Of course, as you could guess, this was not the end of Mahlon.

The Bible makes it very clear that Israel, not Moab, was God’s chosen people. As a reader of this blog, you probably have your doubts about this. This story will make you doubt it even more.

In case you think the Bible is full of boring theology and regulations, you are wrong—the Bible has some dramatic stories, including the book of Ruth the spicy details of which you never hear in church. Put it together with the equally spicy story of Carmen, and you are in for a wild ride.

Robb is an environmentalist who works at the Natural Resources Conservation Service (NRCS), a federal agency which is friendly to farmers, not to the environment. Robb meets DoAnna, who owns a large farm and does everything environmentally wrong. But she knows it and asks Robb for advice. He gives her more advice (such as “Get rid of your cows”) than she wants. But he nearly convinces her to be an eco-farmer until she catches him trespassing on her land to get runoff water samples to identify her farm as a major source of pollution. They had just started to be friends…

Robb loses his job even before DoAnna files a complaint about his trespassing. Depressed and sleepy, he parks his car at a rest stop and falls asleep. He awakens during a severe dust storm and finds DoAnna has prepared him a picnic lunch. She is now convinced he is right—our farms are blowing away in the wind—and she hires him as a full-time advisor on how to make her farm into an eco-farm. They soon become lovers.

Running an eco-farm turns out to be nightmarishly difficult, especially the way Robb and DoAnna do it. The project (raising hemp) fails. They have to start over—but how? They blame each other for what has happened. A summer storm brings on a mud-fight, which leaves them laughing and loving once again.

The point that is of interest to readers of this religion blog is that farming is not just a business. It is a stewardship. That is, the land (thus the farm) belong to God and we have to take care of it and keep it from dying. Farmers cannot do this alone unless everyone else supports them.

This story begins, “Arjana worked in the only place at Joyworld Moscow where you did not have to smile: The Haunted Castle.” Arjana and Zef were two Albanian teenagers from a village destroyed by the Serbs. Arjana couldn’t smile because of what she saw, especially the face of the smiling, ruthless Serbian soldier who chased her and Zef but could not find them. When they sneak onto a train going to Moscow, they find a shipment of costumes for Joyworld, and decide the best place to hide is faraway but in plain sight. Zef played a cowboy at a fake frontier town (Russians were killing Siberians at the same time white Americans were killing Natives). Arjana worked the ticket counter of Haunted Castle, a train that wound through fake graveyards and dangling ghosts. But the soldier found Zef and shot him dead; the visitors thought it was part of an act. Other visitors thought it was part of the act when the soldier found Arjana and tried to rape her. (“The fake blood looks so real!”) But a small and silent act of heroism saves Arjana.

One thing I found very interesting about this story was that Arjana’s ability to play dead was an adaptation to danger. Animal adaptations to escape from danger are as varied as the animals themselves.

An evolutionary puzzle is, why do people so intensely hate those in other racial or cultural groups? An evolutionary argument can be made for why individuals or groups, in competition with one another, would hate each other. But the intensity of hatred seems too much for biology or evolution to explain. It is almost enough to make one believe in Satan.

The Mystery of Joan of Arc

I have been reading Mark Twain’s book (a free online version) about Joan of Arc. As in Connecticut Yankee, Twain presented Joan of Arc as an eyewitness account. According to the legend, Jeanne d’Arc was a sweet and holy little girl in Domremy in eastern France. She seemed to be utterly perfect, as well as beautiful, like Mary Poppins only very humble. Then, suddenly, out of nowhere, she became a military heroine. Nobody who knew her, friends or family, could understand why this happened. She claimed that several saints, and the archangel Michael, had told her that she was the one to rescue France from English rule and to crown the Dauphin, the prince, to be the king of France. And somehow, despite numerous setbacks, she got even her opponents to believe and support her and follow her as she went to see the Dauphin. She had no military training, had never killed anything or anyone with a sword or spear. Like most country children, she could ride a horse. She claimed she would, personally, lead the French army to victory over the English.

This photo is from a church in Strasbourg, France.

At that time, the French army was totally demoralized, and simply accepted the English rulership that had been imposed since the battle of Agincourt. To oppose the English would be suicidal, they thought. But Joan convinced them God would support the French victory.

And the French won against the English army that was gathered at Orleans. Joan was only seventeen years old when the Dauphin, now king, made her the general of the French armies. Almost immediately afterwards, her church enemies had her burned at the stake on what the church now considers trumped-up charges. Almost immediately after this, her case was reconsidered and she was sanctified. She is now one of the great legends of history.

Great uncertainty will always remain about what really happened. Alternative interpretations of the Joan of Arc legend have been presented. Some have claimed that she was mentally unstable, which means she imagined the little voices in her head, or that she had Menière’s disease (an affliction of the inner ear) which means she actually heard sounds but they were not voices. James Phillips and colleagues say that all claims of medical or psychiatric disorders of St. Joan are unconvincing. The claim that she was actually not a simple country girl but was a bastard daughter of the previous king does not explain how she could have, despite weakness and youth, led armies to victory. If indeed she did convince the Dauphin that she was his bastard sister, why would he have let her lead the army instead of doing it himself? The claim that she was a witch substitutes one incredible explanation for another.

Maybe she was crazy, and this made her able to speak her message with utter sincerity and without hesitation. The disillusioned French might have been waiting for just such a person to appear on the scene. The human mind is not a logic machine. Under the right conditions—and nobody can predict exactly what these might be—even the best human minds can believe anything. Among the right conditions are that the human brain’s built in bullshit-detector has to get fooled, something that only a truly and sincerely crazy person can do.

I, like thousands of others, will make my pilgrimage to her birthplace Domremy-la-Pucelle (pucelle means virgin) and walk in the garden where she is supposed to have had her first visions. I will wander and wonder. Domremy is only a two and a half hour drive from where I now live, much closer than Paris. I will wait until my grandchildren are a little older and can appreciate history a little better. If I have any new insights at that time, I will let you know.

Perhaps the strangest thing of all—and one I have not heard reported before—is that this story, of the seventeen-year-old girl leading an army to victory, has happened at least twice and possibly three times or more in history. I will complete this thought in a subsequent essay.
