Joan of Arc and Science

I recently visited the equestrian statue of Joan of Arc (Jeanne d’Arc) in Strasbourg, France. I have posted a video about what I learned.


Joan of Arc was a peasant girl, aged about 17, when she claimed that the Archangel Michael and Saints Margaret and Catherine had told her that she needed to lead the French troops to victory over England, which at that time (1429) occupied a large portion of what is today France. This was during the Hundred Years’ War, and France was not doing too well. The French troops were under siege in Orléans.

Jeanne must have had a mesmerizing personality, because she convinced the future French King Charles VII that the voices in her head had told her France would prevail and Charles would be king. She was put in charge of the portions of the French army that eventually drove the English away from that siege and some others as well. She was a military heroine—a 17 year old peasant girl. The story did not end so well for her. She started losing battles, and when she was 19 she was put on trial and convicted of heresy. She was burned at the stake in 1431. One of the charges was that, in leading battles, she had worn men’s clothing. Later, a new trial found her not guilty and today she is esteemed as one of the patron saints of France. Everyone has heard about her.

Every artistic depiction of her shows her to be very beautiful. The usual standards of physical beauty, however, is not at all necessary. She would have appeared beautiful to those who believed her divine claims, no matter what she actually looked like.

What this means for us, as we examine the role of religion in human history, is that even the craziest of claims are credible if the person making them is persistent and absolutely convinced of them. She heard the little voices in her head and had not the slightest doubt of their authenticity. Many historians today believe that Jeanne was schizophrenic (the little voices were in her brain) or had Menière’s disease (the little voices were in her inner ear). We do not know. More to the point, she did not know.

Religious claims can be made and believed on no further basis than the assertion of those who make them. No other evidence is needed. Many people claim that there is, in fact, evidence other than assertions that support many religious beliefs, such as Jesus’ resurrection. But such evidence is not necessary to true believers.

Scientific thinking, however, requires that the person making a claim provide evidence that is verifiable to people other than the one making the claim. You can read more about it in my book Scientifically Thinking. This is an important reason that we should depend on science, rather than religious assertion, to guide us in making decisions of worldwide importance—which nearly all of our decisions are these days.

The Dark Ages, Coming to a Campus near You

On Halloween, a preacher came to our campus (Southeastern Oklahoma State University) and started yelling about how much God hated women (he said that all women on our campus were sluts), how much God hated Muslims (his shirt read “Allah is Satan,” even though Allah is the translation of the same word the Old Testament uses for God), and how black people should just accept their inferior lot and let white people rule them, all in the name of God.

I have borrowed these photos from Amy Elizabeth Kennedy's Facebook posting.






He had permission to come and speak outdoors by the clock tower (well, what passes for one on our campus; a clock on a pole) but he got that permission by lying to the university staff about what he was going to do. He said he was coming to share the Gospel, but of course there was no Gospel whatsoever in anything that he said.

He accomplished his purposes. He wanted to make people angry. He succeeded in making all of the students who heard him upset (not one student took his side, not even our redneck Trump-supporting students). Some of these upset students simply went away. But when the preacher started verbally attacking black students, one black student started to get physically rowdy (wouldn’t you?) while several other black students held him back. The situation got so tense that police had to escort the preacher off campus. His visit was, to him, successful. He wanted to show us how much, according to him, God hates us, and he succeeded in doing that. He wanted an angry response, and he got it. Now he can go back to his donors and say, “See, what did I tell you? I told you Satan would attack me.” (I have heard fundamentalist Christians say that the hostility of the world is proof that you are doing God’s will. By that definition, Hitler was doing God’s will.)

And he left behind him an impotent and confused discussion about how to prevent such incidents in the future. Everyone seems to be saying that we cannot restrict any form of free speech on campus. This is ridiculous. We already restrict speech that would, for example, recruit terrorists or encourage murder. Speech is not unlimited and never has been. I believe that anyone speaking on campus should be sponsored by a class or by a recognized student organization. If we let just anybody come and speak, no matter how hateful their words, how can we be sure they don’t have guns also? And maybe, for all we know, this preacher did.

The story had a different ending on All Saints Day at East Central University. East Central knew this preacher was coming. When he arrived, he proceeded to exercise his first amendment rights, only to discover that the marching band, at exactly the same time and place, was exercising theirs. Guess who won!

I do not know the name of this preacher’s “ministry,” but whatever it is, he should rename it “Make Jesus Look like an Asshole Ministry.” Because this is what he succeeded in doing. Say all you will about how most Christians are not like him. But such a large number of self-identified Christians are hate-filled racists, though few of them are so vocal about it, that I wonder whether this preacher might represent the norm of American conservative Christianity. I suspect that, in fact, this man reflects what American Christianity is like. Good Christians who preach peace and love may, in fact, be a minority in this country, at least among fundamentalists. All you have to do is see the breathtakingly large number of fundamentalist Christian organizations that endorse Donald Trump, whose entire message is how much he hates anyone who fails to revere him; Donald Trump, whose slogan should be, Make America Hate Again.

The impression I took away from this incident is not that Jesus is an asshole—this incident had nothing to do with Jesus—but that on the whole, at least in America, religion is a negative force and I hope we get rid of it as much and as soon as possible. When you consider what America is like, and the Bible Belt states more than the others, you can get an idea of the fruits of religion. Poverty, drug abuse, teenage pregnancy, and violent crime are rampant in the most Christian parts of America. In order to find a society in which people are, by and large, nice to one another, you have to look at countries such as France. When I visited, as a family member not just a tourist, I was astonished at how well people treated their neighbors and fellow citizens and visitors. The sooner we can become more like France, and leave Christianity behind, we will be a better society. A society that, in fact, more closely resembles Jesus. We need a secular society if we are to survive as a free country.

I am sure it has not escaped the attention of anyone that fundamentalist religion is pushing—perhaps significantly—toward the establishment of a religious dictatorship. Remember, they have guns and they believe God has given them permission to use them however they want.

I am particularly angry that I spent so much of my life suckered into religion. I lost decades of my life to having my brain warped by creationism and fundamentalism. Though I left doctrinal Christianity behind over a decade ago, it took an incident such as this to allow me to see how ugly and despicable my erstwhile religious views were.


Creationism is not about science. It has one purpose only: to support a hatred version of religion and get it established in a powerful position so that they can control the thoughts and lives of the rest of us. Arguing science with a creationist? Don’t bother. They don’t even know what’s in the Bible, much less about science.

Are We All Deluded?

Sam Kean’s new book, The Tale of the Dueling Neurosurgeons: The History of the Human Brain As Revealed by True Stories of Trauma, Madness, and Recovery, is a gold mine of stories about the weird things that our brains can make us do, everything from cortical blindness to alien hand and walking dead syndromes. In people with cortical blindness, the eyes and optic nerves work fine, but the portion of the brain that consciously interprets vision is impaired. The brain has a whole separate set of nerves that process the emotional response to vision, however; people with cortical blindness can therefore smile in response to another person’s smile even though they cannot consciously see it. In alien hand syndrome, a person cannot recognize their own hand—usually the left one—as being part of his or her own body; and in walking dead syndrome, the person cannot recognize the body itself as his or her own.

Perhaps most important, although not the most interesting story in the book, was the experiment that demonstrated that our brain’s conscious decision to do something occurred after the subjects had begun to do the action. That is, the brain’s decision was actually a post-hoc rationalization. This calls into question the entire concept of free will. It appears that we choose to do something only after our subconscious minds have decided to do that thing. Of course, this does not mean we have no conscious control over ourselves. Our conscious minds can prevent us from doing the things we have started to do; that is, however much free will is called into question, self-control is certainly real. As the author says, we may not have free will, but we have free won’t. Also, our conscious minds can create a general pattern of thought that, while it may not control every individual action, certainly influences our general behavior.

The main point of all these fascinating stories is, in the author’s own words: “But if the history of neuroscience proves anything, it’s that any circuit for any mental attribute—up to and including our sense of being alive—can fail, if just the right spots [of the brain] suffer damage…your actions, your desires to act, and your conviction of having acted can all be decoupled and manipulated.”

I have, through reading this book, come to understand myself better. Temporal lobe epilepsy includes the experience of auras that are religious in their effects and intensity—religious delusions. While religion does not consist only of delusion, it has been stimulated by delusion. Famous religious figures, such as the Apostle Paul, Mohammed, and Joan of Arc, and writers such as Dostoevsky to whom religion was of overwhelming importance, showed symptoms of epilepsy. Though I do not have epilepsy, I have some symptoms that suggest my right temporal lobe might be hyperactive in something of the same way as certain epileptics. For example, throughout my life I have had experiences of religious ecstasy. I also have to take an anticonvulsant medication that is prescribed, in higher dosage, to epileptics. And I have a mild case of polygraphia—the compulsion to write everything down, all day every day—that some epileptics also have. Finally, there might be a genetic basis for this; my paternal grandfather was religiously crazy. Somehow just knowing this makes me feel more comfortable inside my skin.

Kean’s book, like the books of Mary Roach, show that the best modern science writing is based on stories and are written to be fun. Filled with fragments and imprecise language, this book would make some science editors howl, but is exactly the kind of book that would make anyone want to learn more about science. This is the kind of science book that I have not yet written myself.

The feeling I bring away from Kean’s book is liberation. I feel no need to blame myself for feeling or believing things that may be outrageous, nor do I have to blame others for theirs. What we need to do is to override anything outrageous that our minds manufacture. The idea that we choose our beliefs rationally seems to be entirely wrong, even though reasoning is a contributing factor. As a scientist and educator, I feel liberation, because I do not need to actually convince or convert anyone to my way of thinking. What I need to continue doing is to provide information and opportunity that will allow my students and my readers to convert their thinking, should that prove possible. If I continue to provide information about the world and its history, humans and their history, and continue provoking new thoughts, I have done my entire job.

The Evolution of Delusion (a Thanksgiving Day Message)

Today is Thanksgiving. But it is also the fortieth anniversary of Yukio Mishima’s seppuku.

Yukio Mishima was a Japanese writer who sometimes wrote feel-good novels (e.g. The Sound of the Waves) and very rarely even humor (e.g. the short story Tamago, or Eggs). But he was most famous for writing fiction with angst, much of which was focused on the loss of the spirit of Japan (Yamato damashii). As I understand it, his mind was in the grip of a delusion that Japan had a glorious samurai past, where warriors had total honor and would rather commit ritual suicide than to submit to any loss of face. The ritual suicide was, of course, seppuku, which is the same as harakiri—the former is the fancy, the latter the ordinary, way of saying it in Japanese. He had a small cult of young men who followed him, like a band of samurai, or perhaps like ronin, the wandering samurai who had no home after Japan entered the modern world in the nineteenth century. But this was post-World-War-II Japan, with no room for either samurai or seppuku.

To Mishima, Japan’s defeat in World War II was an intolerable loss of face. And quite possibly he was influenced by his own cowardice during World War II: when he was drafted, he told the doctors at his physical exam that he had tuberculosis, and he was relieved from Army duty. It was not until 1967 that he joined the postwar version of the Japanese army (the Self Defense force; Japan’s constitution, written by the United States, forbade an army capable of international expansion). He considered this army to not be patriotic enough, so he formed the Tatenokai (Shield Society) in 1968, which upheld bushido (the way of the warrior) and swore to uphold the Emperor. However, he did not think that even Emperor Hirohito was patriotic enough, because Hirohito had renounced his own divinity at the end of World War II.

Mishima was one of the last holdouts of the delusions that were widespread in Japan before and during World War II. Such delusions can, as the Hakko Ichiu principle (Japanese world dominion) did, grip an entire nation. But even this was not enough for Mishima and his followers. On November 25, 1970, Mishima and four members of his Tatanokai visited the commandant of the Tokyo headquarters of the Self-Defense Force. Once inside, they barricaded the office and tied the commandant to his hair. Then Mishima stood on a balcony and delivered a prepared speech, about returning Japan to its glory, to the soliders who had gathered below. He asked the soldiers to join him in a coup d’etat, but they just jeered him. He finished his speech, went into the commandant’s office, and committed harakiri. After he had partially disemboweled himself, one of his assistants was supposed to behead him, in the traditional manner; but this assistant was unable to do so, and another assistant had to finish the job for him. It is now generally believed that Mishima had not intended the coup to be successful, but had planned his ritual suicide for years, and he had made sure his legal affairs, including money for the legal defense of the remaining Tatenokai members, were in order before his final battle.

Delusions can completely determine what a person considers to be reality. Every piece of sensory information is interpreted as a reinforcement of the delusion. This might seem to be an imperfection of the brain that evolution would have gotten rid of. But delusions can sometimes provide evolutionary advantages to the people who have them and to the societies in which these people live. If you have two tribes, one of which has delusions of being God’s chosen conquerors of the world and the other of which values reason over emotion, guess which one will win the war. If a delusional tribe wins territory and resources, its individual members, to varying degrees, will have greater evolutionary fitness. The human mind is capable of intense delusion, and this is the product of natural selection.

Well, I have tied this story in with evolution and religion. Let me finally tie it in with Thanksgiving. Americans have a delusion, even if only mildly held, that the Pilgrims were heroic pioneers who came to the New World from England for religious freedom. But after leaving England, they mad moved to the Netherlands, where they had religious freedom—but so did everyone else. The Pilgrims wanted the “freedom” to enforce their religion, so they had to form their own colony, in Massachusetts. When they got there, they nearly starved, but were rescued by the welfare provided to them by a socialistic Native American tribe. Later, they showed their gratitude by carrying out genocide against this tribe. Pilgrim leader William Bradford describes the way the colonists surrounded a Pequot village at sunrise. They set it ablaze and killed anyone who fled. Bradford wrote, “It was a fearful sight to see them thus frying in the fire and the streams of blood quenching the same, and horrible was the stink and scent thereof; but the victory seemed a sweet sacrifice, and they [the colonists] gave praise thereof to God, who had wrought so wonderfully.” They were able to ignore the suffering that they inflicted on their fellow humans because their brains were deluded with the idea that they were God’s chosen people upon the face of the Earth and had the right, even the responsibility, to slaughter anyone (at least any Indian) who questioned their delusion.

But let me end with something to be thankful for on this day. Evolution has given our species the ability to create, in our minds, a beautiful world based upon the sensory information that those minds receive—brilliant color, wonderful scents of food, beautiful music. They are illusory creations of our minds, but let us enjoy them anyway. They are more beauty than we, the products of natural selection, have any right to have expected.
