Knowledge, Conviction, and Belief [9]:  Reckoning With Mystery

pontius pilate

“What is truth?”
Pontius Pilate
John 18:38 (NIV)

On the science side of Cartesian dualism, truth must be falsifiable — we have to be able to prove it’s untrue. On the religious side, to falsify is to doubt, doubt becomes heresy, and heresy meets the bad end it deserves.

Neither side likes mystery, because both are trying to satisfy a more primal need:  to know, explain, and be right. It’s a survival skill:  we need to be right about a lot of things to stay alive, and there’s nothing more primal to a mortal being than staying alive. Mystery is nice if you’ve got the time, but at some point it won’t help you eat and avoid being eaten.

Science tackles mysteries with experiments and theories, religion with doctrine and ritual. Both try to nail their truth down to every “jot and tittle,” while mystery bides its time, aloof and unimpressed.

I once heard a street preacher offer his rationale for the existence of God. “Think about how big the universe is,” he said, “It’s too big for me to understand. There has to be a God behind it.” That’s God explained on a street corner:  “I don’t get it, so there has be a higher up who does. His name is God.” The preacher’s God has the expansive consciousness we lack, and if we don’t always understand, that’s part of the deal:

“For my thoughts are not your thoughts,
neither are your ways my ways,”
declares the Lord.
“As the heavens are higher than the earth,
so are my ways higher than your ways
and my thoughts than your thoughts.”

Isaiah 55:8-9 (NIV)

Compare that to a cognitive neuroscientist’s take on our ability to perceive reality, as explained in this video.

“Many scientists believe that natural selection brought our perception of reality into clearer and deeper focus, reasoning that growing more attuned to the outside world gave our ancestors an evolutionary edge. Donald Hoffman, a cognitive scientist at the University of California, Irvine, thinks that just the opposite is true. Because evolution selects for survival, not accuracy, he proposes that our conscious experience masks reality behind millennia of adaptions for ‘fitness payoffs’ – an argument supported by his work running evolutionary game-theory simulations. In this interview recorded at the HowTheLightGetsIn Festival from the Institute of Arts and Ideas in 2019, Hoffman explains why he believes that perception must necessarily hide reality for conscious agents to survive and reproduce. With that view serving as a springboard, the wide-ranging discussion also touches on Hoffman’s consciousness-centric framework for reality, and its potential implications for our everyday lives.”

The video is 40 minutes long, but a few minutes will suffice to make today/s point. Prof. Hoffman admits his theory is counterintuitive and bizarre, but promises he’s still working on it (moving it toward falsifiability). I personally favor scientific materialism’s explanation of consciousness, and I actually get the theory behind Prof. Hoffman’s ideas, but when I watch this I can’t help but think its’s amazing how far science and religion will go to define their versions of how things work. That’s why I quit trying to read philosophy:  all that meticulous logic trying to block all exits and close all loopholes, but sooner or later some mystery leaks out a seam, and when it does the whole thing seems overwrought and silly.

The street preacher thinks reality is out there, and we’re given enough brain to both get by and know when to quit trying and trust a higher intelligence that has it all figured out. The scientist starts in here, with the brain (“the meat that thinks”), then tries to describe how it creates a useful enough version of reality to help us get by in the external world.

The preacher likes the eternal human soul; the scientist goes for the bio-neuro-cultural construction we call the self. Positions established, each side takes and receives metaphysical potshots from the other. For example, when science clamors after the non-falsifiable multiverse theory of quantum physics, the intelligent designers gleefully point out that the so-called scientists are leapers of faith just like them:

“Unsurprisingly, the folks at the Discovery Institute, the Seattle-based think-tank for creationism and intelligent design, have been following the unfolding developments in theoretical physics with great interest. The Catholic evangelist Denyse O’Leary, writing for the Institute’s Evolution News blog in 2017, suggests that: ‘Advocates [of the multiverse] do not merely propose that we accept faulty evidence. They want us to abandon evidence as a key criterion for acceptance of their theory.’ The creationists are saying, with some justification: look, you accuse us of pseudoscience, but how is what you’re doing in the name of science any different? They seek to undermine the authority of science as the last word on the rational search for truth.

“And, no matter how much we might want to believe that God designed all life on Earth, we must accept that intelligent design makes no testable predictions of its own. It is simply a conceptual alternative to evolution as the cause of life’s incredible complexity. Intelligent design cannot be falsified, just as nobody can prove the existence or non-existence of a philosopher’s metaphysical God, or a God of religion that ‘moves in mysterious ways’. Intelligent design is not science: as a theory, it is simply overwhelmed by its metaphysical content.”

And so it goes. But what would be so wrong with letting mystery stay… well, um… mysterious?

We’ll look at that next time.

Knowledge, Conviction, and Belief [8]: Science and Snake Oil

snake oil salesman 2

Science requires that its findings be falsifiable:  you have to be able to prove them wrong. That they might be right isn’t enough; if they can’t be wrong, they’re not science.

Belief in the supernatural isn’t falsifiable, therefore it’s not science:

“Most supernatural religious beliefs aren’t falsifiable. The existence of a God who created and manages the world according to a fixed eternal plan, Jesus’s miracles and resurrection, Heaven, Hell, Satan’s presence on Earth — these can never be disproved.”

Fantasyland:  How American Went Haywire, a 500-Year History,by Kurt Andersen (2017)

“We should never believe a claim to be true simply because no one can prove it to be false. Theologians are experts at this kind of nonsense.

“We often see what we already believe is there, not what is actually in front of us. Perhaps the greatest of all examples of this are religious experiences. People with religious experiences always see in their visions what they have been taught all their lives. For example, a Muslim will never see a vision of Jesus in his religious experience and a Christian will never see Mohammed.

“All scientists know that the methods we use to prove or disprove theories are the only dependable methods of understanding our universe. All other methodologies of learning, while appropriate to employ in situations when science cannot guide us, are inherently flawed. Reasoning alone — even the reasoning of great intellects — is not enough. It must be combined with the scientific method if it is to yield genuine knowledge about the universe.”

The Great Illusion:  The Myth of Free Will, Consciousness, and the Self, Paul Singh (2016)

Consider falsifiability’s take on homeopathic medicine:

“Homeopathy, its fake medicines prescribed to cure every disease, is a product of magical thinking in the extreme.”

Fantasyland

“We can find many ways to criticise the premises of homeopathy and dismiss this as pseudoscience, as it has little or no foundation in our current understanding of Western, evidence-based medicine… Even if we take it at face value, we should admit that it fails all the tests: there is no evidence from clinical trials for the effectiveness of homeopathic remedies beyond a placebo effect. Those who … continue to argue for its efficacy are not doing science. They are doing wishful-thinking or, like a snake-oil salesman, they’re engaged in deliberate deception.

But Is It Science? Aeon Magazine, Oct. 7, 2019.

“Homeopathy was the original ‘alternative medicine,’” Kurt Andersen writes. He describes how it was soon joined by mesmerism, phrenology, séances, and traveling snake oil salesmen, brought to us by illustrious champions such as Methodist John Wesley, Presbyterian Sylvester Graham (as in graham crackers), John Kellogg (of cereal fame), and “Dr. William A. Rockefeller, Celebrated Cancer Specialist” (father of John D. Rockefeller of Standard Oil), Along the way, it helped to spawn “New Thought” religion — e.g., Mary Baker Eddy’s Christian Science churches and today’s New Age movement.

Alternative medicine works because of the placebo effect:

“Many nostrums were the products of knowing charlatans, but many of the most successful inventors and promoters were undoubtedly sincere believers themselves. If the patients who had faith in the miraculous treatments, they could even seem to work. The term placebo had just come into use as a medical term.

“The upside was that homeopathy inherently fulfills the Hippocratic Oath:    . Homeopathic medicines contain negligible active ingredients. If thousands of homeopaths and millions of patients, as Mark Twain said, wanted to ‘bribe death with a sugar pill to stay away,’ that was their problem.”

Fantasyland

In her book Mind Over Medicine: Scientific Proof That You Can Heal Yourself, Lissa Rankin M.D. tells how she switched from conventional to alternative medicine after realizing that lots of people in placebo control groups actually do get better taking those sugar pills. They may be in the minority, but still…. I once heard a medical researcher tell a group of MS patients to “Find your placebo — if you think it will help you, it probably will.”

But placebos aren’t science, and the “Scientific Proof” in Dr. Rankin’s book title is off target. Last time we heard about the science behind your GPS. You don’t want it to “probably” work, or work just some of the time, or so rarely it’s a “miracle” when it does. You want it to work every time, everywhere. If it doesn’t, then the science behind it has been falsified (proven wrong), and it’s back to the drawing board.

Eventually science and investigative journalism teamed up to put the snake oil peddlers out of business:

“[At the start of the Twentieth Century,] medical science advanced, and the American Establishment decided to put an end to large-scale quackery. The new mass-market magazine Ladies’ Home Journal stopped accepting ads for patent medicines, and Collier’s published a game-changing eleven-part  investigative series on the ‘tonics,’ ‘blood purifiers,’ and ‘cures’ racket — and a year later the Pure Food and Drug Act became federal law, putting most of that industry out of business.”

Fantasyland

We’ve been digressing a bit. Next time, we’ll get back to what this has to do with consciousness and the self.

Knowledge, Conviction, and Belief [7]: Science and Metaphysics

college photo op

It’s a fine September day during freshman orientation week, and we’re a photo op:  a circle of students on the grass outside a stately hall of higher education. Our leader asked us to tell each other what we hope to learn while we’re here. “I’m interested in metaphysics,” one girl says. I don’t know what that means, and being a clueless frosh, I don’t bother to find out until decades later. [1]

This is from Online Etymology:

metaphysics (n.)

“the science of the inward and essential nature of things,” 1560s, plural of Middle English metaphisikmethaphesik (late 14c.), “branch of speculation which deals with the first causes of things.” … See meta- + physics.

“The name was given c.70 B.C.E. … to the customary ordering of [Aristotle’s Physics], but it was misinterpreted by Latin writers as meaning “the science of what is beyond the physical.”

Metaphysics is what happens when scholars think about the big picture. René Descartes was doing metaphysics when he split reality into seen vs. unseen, knowable vs. mysterious:  “He developed a metaphysical dualism that distinguishes radically between mind… and matter.” Encyclopaedia Britannica.

Metaphysics catches some grief about whether it’s a legitimate academic discipline, but counters that you can’t think about… well, anything… without first thinking about the bigger picture:

Metaphysics, the philosophical study whose object is to determine the real nature of things—to determine the meaning, structure, and principles of whatever is insofar as it is. Although this study is popularly conceived as referring to anything excessively subtle and highly theoretical and although it has been subjected to many criticisms, it is presented by metaphysicians as the most fundamental and most comprehensive of inquiries, inasmuch as it is concerned with reality as a whole.”

Encyclopedia Brittanica:

Even science has to concede metaphysics’ primacy:

“It turns out to be impossible even to formulate a scientific theory without metaphysics, without first assuming some things we can’t actually prove, such as the existence of an objective reality and the invisible entities we believe to exist in it.

“This is a bit awkward because it’s difficult, if not impossible, to gather empirical facts without first having some theoretical understanding of what we think we’re doing.

“Choosing between competing theories that are equivalently accommodating of the facts can become a matter for personal judgment, or our choice of metaphysical preconceptions or prejudices.”

But Is It Science? Aeon Magazine, Oct. 7, 2019. (The remaining quotes are also from this source.)

Scientific inquiry begins subjectively — with beliefs and assumptions that can’t be scrutinized by scientific method — a detail which, if left unintended, puts scientific inquiry on a par with, let’s say, late night dorm conjecture about the meaning of life. Science tries to rise above by requiring that its theories be falsifiable:  they have to be expressed in a way that lets you objectively prove them wrong.

“The philosopher Karl Popper argued that what distinguishes a scientific theory from pseudoscience and pure metaphysics is the possibility that it might be falsified on exposure to empirical data. In other words, a theory is scientific if it has the potential to be proved wrong.”

Falsifiability means you can’t appeal to metaphysics to avoid empirical scrutiny. Trouble is, our brains, once wired with our beliefs, make sure our experience conforms to them. But still…

“For me at least, there has to be a difference between science and pseudoscience; between science and pure metaphysics, or just plain ordinary bullshit.”

To be reliable, science has to make sure its metaphysics and physics line up in actual experience. For example, whatever  your metaphysical theory of the grand cosmos, you still need physics to make your GPS work:

“When you use Google Maps on your smartphone, you draw on a network of satellites orbiting Earth at 20,000 kilometres, of which four are needed for the system to work, and between six and 10 are ‘visible’ from your location at any time. Each of these satellites carries a miniaturised atomic clock, and transmits precise timing and position data to your device that allow you to pinpoint your location and identify the fastest route to the pub. “But without corrections based on Albert Einstein’s special and general theories of relativity, the Global Positioning System would accumulate clock errors, leading to position errors of up to 11 kilometres per day. Without these rather abstract and esoteric – but nevertheless highly successful – theories of physics, after a couple of days you’d have a hard time working out where on Earth you are.

“In February 2019, the pioneers of GPS were awarded the Queen Elizabeth Prize for Engineering. The judges remarked that ‘the public may not know what [GPS] stands for, but they know what it is’. This suggests a rather handy metaphor for science. We might scratch our heads about how it works, but we know that, when it’s done properly, it does.”

More about falsifiability vs. faith, subjective vs. objective, real vs. fantasy, and other Cartesian dualisms next time.

[1] Now that I know what “metaphysics” means, I realize I was interested in it, too. In fact, metaphysics has been something of a defining pursuit of mine for most of my life, although less so lately. More on that another time.

Knowledge, Conviction, and Belief [6]: “The Meat Thinks”

they're made out of meat 2

“The brain does the thinking — the meat.”

Last time, we looked at neuroscience’s idea that consciousness — and therefore the conscious self — is a conglomerate of various neural networks that process experience. In other words, the internal voice that narrates your life, that you’ve been hearing for as long as you can remember, isn’t the voice of a transcendent soul commenting about your Earthly experience, it’s the result of the biological functioning of your brain. Your brain matter — the meat, as sci-fi writer Terry Bisson called it in an Omni Magazine story back in 1991 — does the thinking.

Bisson’s sci-fi piece anticipated neuroscientific materialism by nearly two decades (not an unusual thing for sci-fi to do — sometimes it’s even intentional[1]). Here’s the full text of the short story, which consists entirely of a conversation between an undercover extra-terrestrial and his superior, as the agent reports on his investigation of the human race. The story was made into a six-minute film, which you can watch here. Here’s an excerpt:

They’re made out of meat.”

“Meat?”

“Meat. They’re made out of meat.”

“Meat?”

“There’s no doubt about it. We picked up several from different parts of the planet, took them aboard our recon vessels, and probed them all the way through. They’re completely meat…. They’re born meat and they die meat … They’re meat all the way through.”

“No brain?”

“Oh, there’s a brain all right. It’s just that the brain is made out of meat! That’s what I’ve been trying to tell you.”

“So what does the thinking?”

“You’re not understanding, are you? You’re refusing to deal with what I’m telling you. The brain does the thinking. The meat.”

“Thinking meat! You’re asking me to believe in thinking meat!”

“Yes, thinking meat! Conscious meat! Loving meat. Dreaming meat. The meat is the whole deal! Are you beginning to get the picture or do I have to start all over?”

“Omigod. You’re serious then. They’re made out of meat.”

“Thank you. Finally. Yes. They are indeed made out of meat.”

Conscious meat — the idea is preposterous to the aliens and to us. True, “meat” is an indelicate way to put it, which of course is intentional, but knowing that the term is a clever literary device doesn’t help us accept the idea, any more than we’re willing to accept the formal neuroscientific version we looked at last time:

 “In the present theory, the content of consciousness, the stuff in the conscious mind, is distributed over a large set of brain areas, areas that encode vision, emotion, language, action plans, and so on. The full set of information that is present in consciousness at any one time has been called the “global workspace.” In the present theory, the global workspace spans many diverse areas of the brain. But the specific property of awareness, the essence of awareness added to the global workspace, is constructed by an expert system in a limited part of the brain…. The computed property of awareness can be bound to the larger whole… One could think of awareness as information.”

Consciousness and the Social Brain. Michael S. A. Graziano (2013)

Sci-fi version or neuroscience version — either way, the message is preposterous:  “Thinking meat! You’re asking me to believe in thinking meat!”

Yes, as a matter of fact. And also as a matter of fact, that “preposterous!”  judgment is at least in some measure a case of “refusing to deal with what I’m telling you.” Revolutionary scientific paradigm shifts don’t easily become mainstream. The idea that the Earth isn’t flat has been around way longer than Columbus, but some brains still don’t believe it. The concept of an eternal, transcendent soul has been around even longer; it’s been thoroughly wired into individual and cultural consciousness; we’re convinced that’s the way it is. But now along comes neuroscience, saying that it knows something different. Our well-worn neural pathways tilt at the suggestion. The best we can do is relegate the idea to fiction, where things don’t have to be true — at least not now, although they might become so in the future.

Besides, there’s another, deeper, more pervasive belief at work here — about what it means for science to know something is true.

“But isn’t science in any case about what is right and true? Surely nobody wants to be wrong and false? Except that it isn’t, and we seriously limit our ability to lift the veils of ignorance and change antiscientific beliefs if we persist in peddling this absurdly simplistic view of what science is.

“Despite appearances, science offers no certainty. Decades of progress in the philosophy of science have led us to accept that our prevailing scientific understanding is a limited-time offer, valid only until a new observation or experiment proves that it’s not.”

But Is It Science? Aeon Magazine, Oct. 7, 2019.

Scientific knowledge is throwaway truth — only useable until something better comes along. Conviction, on the other hand, casts its truth in adamantine. Scientific knowledge demands correction, while personal and cultural conviction punishes it.

More next time.

[1] See this article for a look at how science fiction sometimes informs science non-fiction.  Here’s a sample:  “Fictionalising the future can be an effective way of realising it and making it familiar…. As the science-fiction writer Cory Doctorow put it in 2014: ‘There is nothing weird about a company … commissioning a story about people using a technology to decide if the technology is worth following through on. It’s like an architect creating a virtual fly-through of a building.’”

 

Knowledge, Conviction, and Belief [5]: Looking For the Self in the Brain

My soul is lost, my friend
Tell me how do I begin again?
My city’s in ruins,
My city’s in ruins.

Bruce Springsteen

Neuroscience looks for the soul in the brain and can’t find it. What it finds instead are the elements of consciousness — sensory perception, language, cognition, memory,  etc. — in various neural networks and regions of the brain, and those diverse networks collaborating to generate a composite conscious experience. Meanwhile, the master network — the one that is equivalent to conventional notions of the soul or self — remains elusive.

Prof. Bruce Hood lays out the progression from conventional belief in a separate self to the current brain network theory:

“Psychologist Susan Blackmore makes the point that the word “illusion” does not mean that it does not exist — rather an illusion is not what it seems. We all certainly experience some form of self, but what we experience is a powerful deception generated by our brains for our own benefit.

“Understanding that the self could be an illusion is really difficult… Our self seems so convincing, so real to us. But then again, many aspects of our experience are not what they seem.

“In challenging what is the self, what most people think is the self must first be considered. If you were to ask the average person in the street about their self, they would most likely describe the individual who inhabits their body. They believe they are more than just their bodies. Their bodies are something their selves control. When we look in the mirror, we regard the body as a vessel we occupy.

“This sense that we are individual inside bodies is sometimes called the ‘ego theory,’ although philosopher Gale Strawson captures it poetically in what he calls the ‘pearl view’ of the self. The pearl view is the common notion that our self is an essential entity at the core of our existence that holds steady throughout our life. The ego experiences life as a conscious, thinking person with a unique historical background that defines who he or she is. This is the ‘I’ that looks back in the bathroom mirror and reflects who is the ‘me.’

“In contrast to this ego view, there is an alternative version of the self, based on the ‘bundle theory’ after the Scottish Enlightenment philosopher David Hume… He tried to describe his inner self and thought that there was no single entity, but rather bundles of sensations, perceptions and thoughts piled on top of each other. He concluded that the self emerged out of the bundling together of these experiences.

“If the self is the sum of our thoughts and actions, then the first inescapable fact is that these depend on brains. Thoughts and actions are not exclusively the brain because we are always thinking about and acting upon things in the world with our bodies, but the brain is primarily responsible for coordinating these activities. In effect, we are our brains or at least, the brain is the most critical body part when it comes to who we are.

“There is no center in the brain where the self is constructed. The brain has many distributed jobs. It processes incoming information from the external world into meaningful patterns that are interpreted and stored for future reference. It generates different levels and types of motivations that are the human drives, emotions, and feelings. It produces all sorts of behavior — some of them automatic while other are acquired thought skill, practice, and sheer effort.

“The sense of self that most of us experience is not to be found in any one area. Rather it emerges out of the orchestra of different brain processes.”

The Self Illusion:  How the Social Brain Creates Identity, Bruce Hood (2012)

Princeton neuroscientist Michael Graziano uses an “attention schema theory” to describe this collaboration of neural networks. “The heart of the theory is that awareness is a schematized, descriptive model of attention,” he says, and expands as follows:

“In the present theory, the content of consciousness, the stuff in the conscious mind, is distributed over a large set of brain areas, areas that encode vision, emotion, language, action plans, and so on. The full set of information that is present in consciousness at any one time has been called the ‘global workspace.’ In the present theory, the global workspace spans many diverse areas of the brain. But the specific property of awareness, the essence of awareness added to the global workspace, is constructed by an expert system in a limited part of the brain…. The computed property of awareness can be bound to the larger whole… One could think of awareness as information.”

Consciousness and the Social Brain. Michael S. A. Graziano (2013)

To those who hold fast to the common belief (as most people do) that the soul is something transcendent, noble, unique, special, poetic, and divine, referring to consciousness and the self as “global workspace” and calling awareness “information” lacks a little something. But is that any reason to reject the bundle theory as untrue?

Meanwhile, Prof. Graziano admits that “the attention schema theory does not even seek to answer the question of existential reality but instead tries to describe what is constructed by the brain.” And besides, is science really after truth anyway?

We’ll look at those questions next time.

Knowledge, Conviction, and Belief [4]: The Brain vs. the Eternal Soul

brain - illuniated

The period of roughly 2010-2016 apparently was a breakthrough time for neuroscience and the study of consciousness. About then, a scientific consensus began to emerge that the conscious human mind was generated by the brain — or, as some put it, “the mind is what the brain does.”

In a 2016 article[1], University of Sussex professor of cognitive and computational neuroscience Anil K. Seth wrote that,

“In my own research, a new picture is taking shape in which conscious experience is seen as deeply grounded in how brains and bodies work together to maintain physiological integrity – to stay alive.”

Since then, other brain researchers have added a third essential component:  our environment, particularly our cultural setting and its institutionalized belief systems.

Brain, body, environment — that’s it, that’s what brain science has come up with. It went looking for the soul and didn’t find it. As physician and researcher Paul Singh also wrote in 2016[2]:

“The idea of a transcendent self is a myth; the truth is that the self is a constructed self.”

Not only that, but when a consciousness based purely in physicality replaces traditional belief in an eternal, transcendent soul temporarily at home in a physical human body, other companion notions about the self, consciousness, and free will also come tumbling down. Singh admitted this wasn’t going to be easy news to swallow:

“I will be the first one to admit that the debates about the nature of free will, consciousness, and the self are far from over. It is not, however, because we don’t know the answers, but because we are not at a stage of human evolution and progress yet for people to accept such radical ideas. Such truths are scary in the sense that they undermine our ordinary and commonsensical beliefs about human nature and seem to threaten values that we hold dearly — one of the most important of which is moral responsibility.”

Difficult, yes, but not impossible if you can suspend allegiance to the things you’re convinced of and convicted about, and instead give scientific knowledge a try. Singh makes his case with impassioned advocacy of science and the scientific method:

“I believe, however, that the truthfulness of a fact should be judged on its own merit rather than based on its social and emotional implications for the well-being of an individual or society. Truth should be acknowledged first and then solutions sought that will be implemented in light of the good and bad that truth has revealed, not the other way around. Truth is about truth and not about convenience or about making us feel good about ourselves.

“We should never believe a claim to be true simply because on one can prove it to be false. Theologians are experts at this kind of nonsense. Are delusional people making things up? Evidence shows that the human brain is universally delusional in many ways and therefore people who promote superstitions are not particularly more delusional that the rest of us. It is just that examples of religious delusions are rather classic examples of how the brain creates illusions and delusions. The use of logic and scientific skepticism is a skill that can be used to overcome the limitations of our own brains. This skill is like any other skill such as learning to play the piano. It involves training in metacognition as well as basic education in basic sciences.”

Frankly, that kind of rhetoric invariably come across as bombastic and opinionated and therefore easy for those convinced otherwise to dismiss. The well-worn neural pathways of our own brains are deeply rutted with their own notions of what is true, and not about to change to a new paradigm just because someone else is convinced it is the “Truth is about truth.”

On the other hand, in my personal experience, I’ve found that the precursor to scientific knowledge — “scientific skepticism” — is in fact a “a skill that can be used to overcome the limitations of our own brains.” I’ve been developing the skill gradually for years, without intentionally doing so. I was no scientist; I’d spent a lifetime in the humanities; my allegiance was with Romanticism, not the Enlightenment. I was not out to find or prove truth, or convince anybody of it. But I was looking for new thoughts, and years of reading and reflecting — like water carving sandstone — slowly brought my thinking to a new place.

The first time I read about the “materialist” version of consciousness I thought it was just plain odd, which made me highly skeptical. Ironically that skepticism eventually sharpened into a practice that brought me where I don’t find the materialist idea odd at all; in fact, it seems odd to think the way I used to. It now seems simple and obvious that everything we experience is processed within the confines of our largest organ — our skin — and that it has to be that way because, as a biological organism, there’s no other place where it can happen. Even if we think about an eternal, transcendent soul, we do so from our ephemeral, fleshly point of view. That’s all the equipment we’ve got.

Continued next time.

Knowledge, Conviction, and Belief [3]: Dualism – Reality A and Reality B

Janus

We’ve been talking about dualistic thinking — the kind that leads us to think we live simultaneously in two realities.

Reality A is “life in the flesh” — bound by space and time and all the imperfections of what it means to be human. It is life carried on in our physical bodies, where our impressive but ultimately limited brains are in charge.

Reality B is “life in the spirit” — the eternal, perfect, transcendent, idealized, supernatural, original source that informs, explains, and guides its poorer counterpart.

This dualistic thinking says there’s more to life than meets the eye, that humans are an “eternal soul having a worldly existence.” The dualism set ups a cascade of derivative beliefs, for example:

There’s a difference between the Reality A identity and experience we actually have and the Reality B identity and experience we would have if we could rise above Reality A and live up to the idealized version of Reality B.

Every now and then, somebody gets lucky or gets saved or called, and gets to live out their Reality B destiny, which gives them and their lives a heightened sense of purpose and meaning.

But those are the chosen few, and they’re rare. For most of us, our ordinary selves and mundane lives are only a shadow of our “higher selves” and “greater potential.”

The chosen few can — and often do — provide guidance as to how we can do better, and we do well to find some compatible relation with one of more of them, but sometimes, in the right setting and circumstance, we might discover that we have receptors of our own that can receive signals from Reality B. We call this “enlightenment” or “conversion” or “salvation” or something like that, and it’s wonderful, blissful, and euphoric.

But most of the time, for the vast majority of us, Reality A is guided by a mostly one-way communication with Reality B — a sort of moment-by-moment data upload from A to B, where everything about us and our lives — every conscious and subconscious intent, motive, thought, word, and deed — gets stored in a failsafe beyond-time data bank. When our Reality A lives end, those records determine what happens next — they inform our next trip through Reality A, or set the stage for Reality B existence we’re really going to like or we’re really going to suffer.

Everybody pretty much agrees it’s useful to have good communication with or awareness of Reality B, because that helps us live better, truer, happier, more productive lives in Reality A, and because it creates a better data record when our Reality A existence ends and we pass over to Reality B.

And on it goes. No, we don’t express any of it that way:  our cultural belief systems and institutions — religious doctrines, moral norms, legal codes, academic fields of study, etc. — offer better- dressed versions. But it’s remarkable how some version of those beliefs finds its way into common notions about  how life works.

At the heart of it all is our conviction — not knowledge — that this thing we consciously know as “me” is an independent self that remains intact and apart from the biological messiness of human life, able to choose its own beliefs, make its own decisions, and execute its own actions. In other words, we believe in consciousness, free will, and personal responsibility for what we are and do — and what we aren’t and don’t do — during what is only a sojourn — a short-term stay — on Earth.

Those beliefs explain why, for example,  it bothers us so much when someone we thought we knew departs from their beginnings and instead displays a changed inner and outer expression of who they were when we thought we knew them. “Look who’s in the big town,” we say. Or we pity them and knock wood and declare thank goodness we’ve been lucky. Or we put them on the prayer chain or call them before the Inquisition… anything but entertain the idea that maybe Reality B isn’t there– along with all the belief it takes to create it — and that instead all we have is Reality A — we’re nothing but flesh and bone.

It’s almost impossible to think that way. To go there, we have to lay aside conviction and embrace knowledge.

Almost impossible.

Almost.

We’ll give it a try in the coming weeks.

Knowledge, Conviction, and Belief [2]: Cultural Belief and Mass Delusion

We think we have an independent ability to think and believe as we like, to know this or be convinced about that. But that’s not the whole story:  our outlook is also shaped by our cultural context.

As we’ve seen , when enough people agree about what is true — whether they “know” it or are “convinced” of it — their agreement becomes a cultural belief system — for example, as reflected in a religion, country, neighborhood, business, athletic team, or other institution. Cultural belief systems are wired into the neural pathways of individual members, and as the culture coalesces, its belief system takes on a life of its own thorough a process known as “emergence.” As the emergent belief system is increasingly reflected in and reinforced by cultural institutions, it is increasingly patterned into the neural pathways of the culture’s members, where it defines individual and collective reality and sense of identity,  The belief system becomes The Truth , defining what the group and its members know and are convinced of.

Throughout this process, whether the culture’s beliefs are true in any non-subjective sense loses relevance. The result is what physician and author Paul Singh refers to as “mass delusion”:

“[When a conviction moves from an individual to being widely held], its origins are rooted in a belief system rather than in an individual’s pathological condition. It is a mass delusion of the sort that poses no immediate threat to anyone or society. Mass delusions can become belief systems that are passed from generation to generation.”

The Great Illusion:  The Myth of Free Will, Consciousness, and the Self, Paul Singh (2016)

For a dramatic example of this concept in action, consider an experience described by Jesse Jackson:

“There is nothing more painful to me at this stage in my life than to walk down the street and hear footsteps… then turn around and see somebody white and feel relieved.”

Despite a lifetime of civil rights leadership, Jackson’s cultural neural conditioning betrayed him. What he experienced was not just personal to him; it conformed to a cultural belief system. The particular “mass delusion” involved has been confirmed by clinical research.

“Matthew Lieberman, a psychologist at the University of California, recently showed how beliefs help people’s brains categorise others and view objects as good or bad, largely unconsciously. He demonstrated that beliefs (in this case prejudice or fear) are most likely to be learned from the prevailing culture.

“When Lieberman showed a group of people photographs of expressionless black faces, he was surprised to find that the amygdala — the brain’s panic button — was triggered in almost two-thirds of cases. There was no difference in the response between black and white people.”

Where Belief Is Born, The Guardian (June 30,2005)

When cultural beliefs are not constantly reinforced — by cultural norms of thought, language, practice, etc. — the neural networks that support them can weaken, allowing opportunity for new beliefs.

“‘Beliefs are mental objects in the sense that they are embedded in the brain,’ says [Kathleen Taylor, a neuroscientist at Oxford University] ‘If you challenge [beliefs] by contradiction, or just by cutting them off from the stimuli that make you think about them, then they are going to weaken slightly. If that is combined with very strong reinforcement of new beliefs, then you’re going to get a shift in emphasis from one to the other.’”

Where Belief Is Born

This helps to explain, for example, why religious believers are more likely to “fall away” if they are “out of fellowship.” Or what can happen to a student off to college, a world traveler, or an immigrant. It also helps to explain why leaders and despots alike can manipulate brain networks to create cultural belief systems to fit their desired ends:

“In her book on the history of brainwashing, Taylor describes how everyone from the Chinese thought reform camps of the last century to religious cults have used systematic methods to persuade people to change their ideas, sometimes radically.

“The mechanism Taylor describes is similar to the way the brain learns normally. In brainwashing though, the new beliefs are inserted through a much more intensified version of that process.

“The first step is to isolate a person and control what information they receive. Their former beliefs need to be challenged by creating uncertainty. New messages need to be repeated endlessly. And the whole thing needs to be done in a pressured, emotional environment.

“Stress affects the brain such that it makes people more likely to fall back on things they know well – stereotypes and simple ways of thinking,” says Taylor.

“This manipulation of belief happens every day. Politics is a fertile arena, especially in times of anxiety.”

Knowledge, Conviction, and Belief

For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers,  neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.”

Paul’s letter to the Romans 8:38-39 (NIV)

How did Paul know that? Why was he so convinced?

According to psychology and neuroscience, he didn’t know it, he was convinced of it. The difference reflects Cartesian dualism:  the belief that we can know things about the natural world through scientific inquiry, but in the supernatural world, truth is a matter of conviction.

Academics draw distinctions between these and other terms,[1] but in actual experience, the essence seems to be emotional content. Scientific knowledge is thought to be emotionally detached — it wears a lab coat, pours over data, expresses conclusions intellectually. It believes its conclusions, but questioning them is hardwired into scientific inquiry; science therefore must hold its truth in an open hand — all of which establish a reliable sense of what is “real.” Conviction, on the other hand, comes with heart, with a compelling sense of certainty. The emotional strength of conviction makes questioning its truth — especially religious convictions — something to be discouraged or punished.

Further, while knowledge may come with a Eureka! moment — that satisfying flash of suddenly seeing clearly — conviction often comes with a sense of being overtaken by an authority greater than ourselves — of being apprehended and humbled, left frightened and grateful for a second chance.

Consider the etymologies of conviction and convince:

conviction (n.)

mid-15c., “the proving or finding of guilt of an offense charged,” from Late Latin convictionem(nominative convictio) “proof, refutation,” noun of action from past-participle stem of convincere “to overcome decisively,” from com-, here probably an intensive prefix (see com-), + vincere “to conquer” (from nasalized form of PIE root *weik- (3) “to fight, conquer”).

Meaning “mental state of being convinced or fully persuaded” is from 1690s; that of “firm belief, a belief held as proven” is from 1841. In a religious sense, “state of being convinced one has acted in opposition to conscience, admonition of the conscience,” from 1670s.

convince (v.)

1520s, “to overcome in argument,” from Latin convincere “to overcome decisively,” from assimilated form of com-, here probably an intensive prefix (see com-), + vincere “to conquer” (from nasalized form of PIE root *weik- (3) “to fight, conquer”). Meaning “to firmly persuade or satisfy by argument or evidence” is from c. 1600. Related: Convincedconvincingconvincingly.

To convince a person is to satisfy his understanding as to the truth of a certain statement; to persuade him is, by derivation, to affect his will by motives; but it has long been used also for convince, as in Luke xx. 6, “they be persuaded that John was a prophet.” There is a marked tendency now to confine persuade to its own distinctive meaning. [Century Dictionary, 1897]

Both knowledge and conviction, and the needs they serve, are evolutionary survival skills:  we need what they give us to be safe, individually and collectively. Knowledge satisfies our need to be rational, to think clearly and logically, to distinguish this from that, to put things into dependable categories. Conviction satisfies the need to be moved, and also to be justified — to feel as though you are in good standing in the cosmology of how life is organized.

Culturally, conviction is often the source of embarrassment, guilt, and shame, all of which have a key social function — they are part of the glue that holds society together. Becoming aware that we have transgressed societal laws or behavioral norms (the “conviction of sin”) often brings not just chastisement but also remorse and relief — to ourselves and to others in our community:  we’ve been arrested, apprehended, overtaken by a corrective authority, and saved from doing further harm to ourselves and others.

Knowledge and conviction also have something else in common:  both originate in the brain’s complex tangle of neural networks:

“It is unlikely that beliefs as wide-ranging as justice, religion, prejudice or politics are simply waiting to be found in the brain as discrete networks of neurons, each encoding for something different. ‘There’s probably a whole combination of things that go together,’ says [Peter Halligan, a psychologist at Cardiff University].

“And depending on the level of significance of a belief, there could be several networks at play. Someone with strong religious beliefs, for example, might find that they are more emotionally drawn into certain discussions because they have a large number of neural networks feeding into that belief.”

Where Belief Is Born, The Guardian (June 30,2005).

And thus protected by the knowledge and convictions wired into our neural pathways, we make our way through this precarious thing called “life.”
