Spiritual quantum fields?

 

Herewith, an intriguing paragraph about physics, biology (the brain), and consciousness:

Wave-particle duality, a fundamental concept of quantum mechanics, proposes that elementary particles, such as photons and electrons, possess the properties of both particles and waves. These physicists claim that they can possibly extend this theory to the soul-body dichotomy. If there is a quantum code for all things, living and dead, then there is an existence after death (speaking in purely physical terms). Dr. Hans-Peter Dürr, former head of the Max Planck Institute for Physics in Munich, posits that, just as a particle “writes” all of its information on its wave function, the brain is the tangible “floppy disk” on which we save our data, and this data is then “uploaded” into the spiritual quantum field. Continuing with this analogy, when we die the body, or the physical disk, is gone, but our consciousness, or the data on the computer, lives on.

This comes from a brief article by Janey Tracey on Outerblogs. I spent a few minutes trying to find more on the physicists she quotes, among them Christian Hellwig, also of Max Planck Institute, and Robert Jahn of Princeton. But I have been too busy to follow up by reading papers and books–between semester mid-term and concerns about our Resident Nonagenarian, who is at present “declining” toward death, things have been…challenging. We are experiencing with our best-beloved the waiting period as the corporeal body shuts down organ by organ, bit by bit, consciousness becoming semi-conscious, then intermittent, and unresponsive, as the mind enters that realm none of us can understand.

Life closes in many ways–swiftly, at times, but more commonly in increments. This death is not the one our best-beloved would have chosen (in one of her recent moments of clarity: “This isn’t what I wanted,” she said). Alas. The slow, to all appearances agonizing, shutting-down toward death probably rates low on most people’s desires list.

The Rolling Stones warned us you can’t always get what you want [skip the ad, listen to the rock n roll]. I suppose that song has already been uploaded onto my spiritual quantum field. Not to mention the spiritual quantum fields of millions of humans. If Dr. Dürr’s speculations are correct, that may mean Mick Jagger, Keith Richards, et al are among the immortals already. And while I am mentioning this possibility with a sense of humor, I do ponder the interesting concept of a quantum code that encompasses human memory-processing, experience, and mind. It seems to be distinctly likely that consciousness is a tangled hierarchy.

Tangled hierarchy as in strange loop, or paradox, explained in Goedel’s Incompleteness Theorems. Douglas Hofstadter, trying to get his mind around the problem of consciousness, suggests that such a “flipping around of causality” appears to happen in minds possessing self-consciousness. The mind perceives itself as the cause of feelings, thoughts, etc. Our 20th-century scientific models posited that feelings and desires are caused solely by the interactions of neurons.

Though maybe quantum theory and biophysics and 21st-century neurological psychology studies will indicate we are still pretty far from the Whole Story.

Meanwhile, one story of one person draws nearer the close. No–that is not the case. The body will die. Her story–her many stories, told from many perspectives, her paradoxes, her own strange loopiness–91 years has only been the beginning.

Dozens of views

No one has ever found the traces of memory in a brain cell. Nor are your imagination, your desires, your intentions in a brain cell. Nothing that makes us human is there.

—Deeprak Chopra

Chopra is not my favorite writer on consciousness, but he does an adequate job of explaining complicated concepts to people who are just getting accustomed to questioning experience and who are beginning to be open-minded about the mind, the body, and beyond. So often, we have been raised not to doubt, told what God is and is not, and trained into beliefs about the truth. This, in spite of the common human trait of curiosity that asks: who and where are we in the world? What makes me me? What happens when I die? Chopra, with his medical background and his experience spanning several major cultures, can offer both a great deal of information and pose provocative questions to his readers.

In our technologically-obsessed culture, it is easy to turn to science as foremost authority; I happen to be fascinated by neurology and neuropsychology when it comes to consciousness, for example, but I never rule out so-called spiritual insights. Chopra’s writing often falls into the fallacy of stating “there are two views,” when in fact there are dozens of views, even among scientists. My guess (it is but a guess) is that the either/or form of presenting perspective is simpler for the “average reader”–as defined by his editor–to understand. Yet it seems to me a slight to the average reader to narrow these big questions down to “two views.”

Here’s an example, just one of many in his writing:

There are two views about consciousness in science today. One is that consciousness is an emergent property of the brain and. therefore, also an emergent property of evolution. That’s the materialist, reductionist view. There’s another view…[that] holds that consciousness is not an emergent property but inherent in the universe.

Now, I genuinely prefer what Chopra calls the “mind first” argument in which consciousness is a kind of field effect. I would not, however, suggest that matter first and mind first are the only two views today’s scientists hold; and neither would anyone else who has read a number of the elegantly-argued, well-researched, thoughtful, passionate blogs of today’s science researchers. The majority of them are atheists, but some are agnostics and some are inclined toward non-theist teachings such as Zen. Even among the ranks of non-believers (in terms of an anchoring eternal presence or god), the question of consciousness leads to intriguing inquiries.

The philosophers of today cannot ignore scientific advances any more than Maimonides could in the 12th century. Physics is a thing! as my students might put it. For the ways in which this relates to the science of neurology, I return to the framework on consciousness proposed by Douglas Hofstadter in his book I Am a Strange Loop.

What is the world but consciousness? Or illusion, in Hindu and Buddhist teachings (Maya) and, in a slightly different but related way, in Plato. And how many perspectives are there on that consciousness?

Chopra would probably say that each of us has to experience a state of awareness and interaction with whatever deep potential “god” or the creating principle offers for us. Which basically admits of not merely dozens but billions of unique interactions or perspectives…if we even agree to the schema.

Consciousness as multiple drafts

Daniel C. Dennett’s 1991 book, Consciousness Explained, has kept me entertained and interested for a couple of days now. How could I refuse a book with that title? And Dennett–whose conversational writing style appears to toss off one idea after another in quick succession–actually stays mostly true to classic philosophical reasoning in his arguments as he endeavors to make claims for what consciousness is. He begins with phenomenology as one way to initiate the concatenation of empirical science (physics, biology, neurological research) with logic. He dispenses with Husserl and the early Phenomenologists but invents his own form–hyperphenomenology–breaking phenomena into three divisions and exploring each until he arrives at a way to destroy the long-held concept of the mind, hence consciousness, as “Cartesian Theatre,” and replace that model with a construction more biologically sound.

The book is far too complex to summarize, but the concept he develops that most appeals to me is what he calls the multiple drafts theory of consciousness. Dennett draws upon neurological and psychological research as well as past and current philosophical thinking to propose that what we term consciousness may consist of multiple narratives created through physical input, memory processing, and other processes that result in fraction-of-a-second “revisions” in thinking. Narratives! Revisions! As a writer, I can certainly relate to this idea. The theory of multiple drafts consciousness would explain many phenomena, such as the unreliability of eyewitnesses, the repression and re-constructing of traumatic experiences, the embellishment of stories (as Dennett puts it, “What I should have said at the party becomes what I said at the party”)…and it has examples in the way we “tell” fiction, movies, and family stories.

Currently, I am engaged in the work of revising dozens and dozens of poems. Many drafts. Many narratives, many layers. Subtle shifts in perspective or story or language or style–which version is the real me? All of them, across a continuum.

Derek Parfit’s Reasons & Persons suggests some of the same conclusions through a more traditional philosophical approach (harder to read than Dennett’s often-humorous prose which is geared more toward the non-philosopher and which employs considerable neurological and psychological research as part of its rational evidence).

Although these texts intrigue, and are convincing, they remain speculative. For me, the science aspects of the inquiry remove none of the mystery or delight I experience in terms of my own consciousness. Nor do they negate my sense of myself as individual, unique as to perspective, or whole in myself and in the cosmos. I know that many people resist the idea that consciousness is not soul, who feel that scientific research somehow diminishes human beings into–what? Fancy hardware for intelligent software? Automatons with the illusion of free will? Purposeless life forms? Robotic zombies with no moral bearings?

A continuum version of tao

Apparently, we desire awe; but knowledge doesn’t have to kill awe.

I find myself fascinated with the ideas posed by Douglas Hofstadter wherein he theorizes consciousness-as-continuum (see this post). People love to default to a black & white way of analysis, thinking, and judging, but everything in nature contradicts that concept. No doubt our brains, wired to make quick decisions using the simplest shortcuts, sieve out a great deal of content and then justify later (Daniel Kahneman’s book Thinking Fast and Slow covers this process in fascinating depth). It’s simply easier to think of balance as tao, perfectly harmonious black and white, or to sort people or objects or ideas into yes-or-no categories. But the distinctions are seldom so clear–there’s a continuum that stretches from the black to the white, as in the spectrum, as in the fringes of a forest or a meadow, as in the so-called races of human beings, as in places where societies and cultures meet and often intermingle, as in the coastline of the sea or a riparian environment. And all of those things are awesome, even miraculous.

In Dennett’s Chapter Five, “Multiple Drafts vs. the Cartesian Theater,” he offers this diagram:

dennett003It’s a proposed version of what happens when we think.

You will have to read the book to decipher this illustration; but I recognize in it the way I tell a story, think about a story, remember an event, record an experience, and the narrative method of the many kinds of stories (many genres, many media) that I love.

One thing it is not is straightforward. We have all those revisions to make, to layer our experiences with, to explore along the fringes of, and to find deeply miraculously awesome. Wading among my drafts now, I feel revitalized. These reflections and revisions are part of my Self as a conscious being in a physical and wonderful world.

 

 

 

Consciousness & cosmology

"Syntax" by Steve Tobin. Copper, bronze.

“Syntax” by Steve Tobin. Copper, bronze. What can be said about all the things we think make up an “I”?

~

I’ve completed I Am a Strange Loop and Why Does the World Exist? and found, not entirely to my surprise (but to my delight–braiding and synthesis!), that the existential, metaphysical, and cosmological aspects of both authors connect intriguingly. Thomas Nagel, an important “philosopher of mind,” appears as an influence in both of these writers’ books, and Einstein and Plato and Heidegger. Both authors end up citing Derek Parfit’s work, and Holt even interviews him! It turns out that trying to determine the “reason” the world exists at all is not that different from trying to understand what consciousness is made of and where it resides.

After taking up mathematical proofs and several philosophical arguments, as well as neurological science as a basis for the evolution of “mind,” Hofstadter’s book gradually takes apart the mind-body problem that Descartes made so iconic for Western civilization’s thinkers. He keeps returning–and that’s an appropriate word–to the metaphor of looping. He looks at the strange loops of Escher’s drawings and of string theorists’ rolled-up dimensions and alerts us to how crucial the concept of self-reference is to the theory of consciousness.

The need for self-referentiality in a fully “human” consciousness gets him to the idea of “small-souledness” (among, say, such beings as mosquitoes). What portion of our selves makes us able to think about thinking, for example? Is that identity, or consciousness? What’s the difference? Here is where Parfit comes in. Hofstadter writes that Parfit “staunchly resists the idea that the concept of ‘personal identity’ makes sense. To be sure, it makes sense in the everyday world we inhabit…we all more or less take for granted this notion of ‘Cartesian Ego’ in our daily lives; it is built into our common sense, into our languages, and into our cultural backgrounds.”

~

If we care at all about what there may be beyond our everyday lives–and certainly people like Hofstadter, Holt, Bachelard, and me, among others, do care–we need to get “meta” in our meditations, which invariably leads to paradoxes and thorny tangles. Hofstadter’s book also engages with his ‘personal life’ (if, indeed, a personal identity or personal life exists). When his wife died, he found himself engaged in the seemingly unanswerable question of “Where did Carol go?” Did “Doug-and-Carol,” the shared dreams and lives and understandings of two people who knew one another intimately, simply vanish when Carol’s body died? Hofstadter cannot fathom that this shared identity “goes poof” when the body stops. He, after all, still feels connected to the Doug-and-Carol shared consciousness.

It feels real to him. So–what is consciousness? From whence does it emanate, or originate? Is it real, or is it an illusion–is there no such thing as the personal identity we hold so dear that we cannot even imagine ourselves any other way than as an “I”? (Are feelings real?)

~

Jim Holt’s book likewise gets more personal as the chapters progress and as he wrestles with his existential inquiry through texts and interviews. That seems quite appropriate: how can we use language to untangle what language itself makes vague and confusing? (See Tobin’s sculpture “Syntax,” above, for a physical view of loopy entanglement and potential words). Holt’s inquiry initially seems based on the abstract, mathematical, physics of why/how the universe got here; but he ends on the metaphysical and philosophical…whereas Hofstadter entertains the metaphysical from the get-go but employs mathematics, psychology, and brain physiology as well as philosophy. And they encounter similar quandaries, paradoxes, and uncertainties. Both authors essentially come to a similar conclusion about the mystery of existence, though they accept or compromise with their conclusions in slightly different ways. Then again, they are different people who have lived different experiences. Reading both books has been, for me, a valuable experience and one that’s made me examine my own thinking about being.

Apropos of these musings, and thanks again to Popova of Brainpickings, here’s a few more words on some contemporary thinkers who have theorized as Holt has (in particular, Lawrence Kraus) in the debate on Something vs. Nothing: “What is Nothing”

Ontologies and inquiries

{ ? }

 

This week, amidst the whirl of returning students, I have accidentally paired my reading of Douglas Hofstadter’s book I Am a Strange Loop with Jim Holt’s Why Does the World Exist?

How did all of this get started? In the most concrete and specific scenario, I had been slowly savoring Hofstadter–and, let’s face it, trying to “get” the math he occasionally employs–and happened across a copy of Holt’s book, which is a faster read, when I didn’t have Strange Loop to hand. Next thing I know, I’m deep into both texts which, naturally, overlap in several ways. Now, I find myself pondering the beginnings of abstract things like consciousness, which may not be abstract if you think along the lines of E. O. Wilson but which Hofstadter suggests exists as both a top-level abstract “thing” that pushes around its foundational, physical “things” such as synapses, neurons, molecules. And I think about Descartes and the mind-body problem and, oh, while I’m at it, the Big Bang theory and the “what was there before the big bang?” question.

Holt’s book turns to the metaphysical inquiry, “Why is there something instead of nothing?” It’s a question I asked myself when I was about 6 years old. Hofstadter deals mostly with the (perhaps metaphysical) concern: “What is consciousness?” That’s a question I asked a bit later in life, though certainly I asked it before I was in my twenties.

Both authors employ philosophy and math in the service of trying to make sense of these inquiries; and while Holt’s investigation is a bit more physical-cosmological in nature, it may not be necessarily so–lots of the theories floating around out there sound pretty metaphysical to me! Hofstadter employs many analogies, as is his wont (see, in particular, his 1979 book Gödel, Escher, Bach). Hofstadter also gets a bit more into neurology, of course–we are talking about consciousness, after all, and it may reside in our brains–and slightly into the arena of psychology. Holt takes a more journalistic approach, using interviews and readings to cite past and current thinking on the topic of existence. The subtitle of his book is “An Existential Detective Story.”

So far, I enjoy both books, though they differ in significant respects.

Meanwhile, at work I am mainly dealing with adjusting-to-updated-software issues and helping-students-with-advising questions and explaining drop-add and pass-fail and comp-rhet and the difference between Elementary Spanish I and II. Keeps my brain flexible and gets those neurons firing. {Right??}

I haven’t finished reading either book yet. I may have more to say about the synthesis of these two books after I’ve let my brain settle down.
