Subjective Science

quantum mechanics formula

What happened to spark all the recent scientific interest in looking for consciousness in the brains of humans and animals, in insects, and … well, everywhere? (Including not just the universe, but also the theoretical biocentric universe and quantum multiverses.)

“It has been said that, if the 20th century was the age of physics, the 21st will be the age of the brain. Among scientists today, consciousness is being hailed as one of the prime intellectual challenges. My interest in the subject is not in any particular solution to the origin of consciousness – I believe we’ll be arguing about that for millennia to come – but rather in the question: why is consciousness perceived as a ‘problem’? How exactly did it become a problem? And given that it was off the table of science for so long, why is it now becoming such a hot research subject?”

I Feel Therefore I Am — How Exactly Did Consciousness Become A Problem? And why, after years off the table, is it a hot research subject now?  Aeon Magazine (Dec. 1, 2015)

From what I can tell, two key sparks started the research fire:  (1) the full implications of quantum mechanics finally set in, and (2) machines learned how to learn.

(1)  Quantum Mechanics:  Science Goes Subjective. Ever since Descartes set up his dualistic reality a few hundred years ago, we’ve been able to trust that science could give us an objective, detached, rational, factual view of the observable universe, while philosophy and religion could explore the invisible universe where subjectivity reigns. But then the handy boundary between the two was torn in the early 20th Century when quantum mechanics found that subjectivity reigns on a sub-atomic level, where reality depends on what researchers decide ahead of time what they’re looking for. Scientists tried for the rest of the 20th Century to restore objectivity to their subatomic lab work, but eventually had to concede.

 “Physicists began to realise that consciousness might after all be critical to their own descriptions of the world. With the advent of quantum mechanics they found that, in order to make sense of what their theories were saying about the subatomic world, they had to posit that the scientist-observer was actively involved in constructing reality.

“At the subatomic level, reality appeared to be a subjective flow in which objects sometimes behave like particles and other times like waves. Which facet is manifest depends on how the human observer is looking at the situation.

“Such a view apalled many physicists, who fought desperately to find a way out, and for much of the 20th century it still seemed possible to imagine that, somehow, subjectivity could be squeezed out of the frame, leaving a purely objective description of the world.

“In other words, human subjectivity is drawing forth the world.”

I Feel Therefore I Am

(2)  Machines Learned to Learn. Remember “garbage in, garbage out”? It used to be that computers had to be supervised — they only did what we told them to do, and could only use the information we gave them. But not anymore. Now their “minds” are free to sort through the garbage on their own and make up their own rules about what to keep or throw out. Because of this kind of machine learning, we now have computers practicing law and medicine, handling customer service, writing the news, composing music, writing novels and screenplays, creating art…. all those things we used to think needed human judgment and feelings. Google wizard and overall overachiever Sebastian Thrun[1] explains the new machine learning in this conversation with TED Curator Chris Anderson:

 “Artificial intelligence and machine learning is about 60 years old and has not had a great day in its past until recently. And the reason is that today, we have reached a scale of computing and datasets that was necessary to make machines smart. The new thing now is that computers can find their own rules. So instead of an expert deciphering, step by step, a rule for every contingency, what you do now is you give the computer examples and have it infer its own rules.

 “20 years ago the computers were as big as a cockroach brain. Now they are powerful enough to really emulate specialized human thinking. And then the computers take advantage of the fact that they can look at much more data than people can.

No wonder science got rattled. Like the rest of us, it was comfortable with all the Cartesian dualisms that kept the world neatly sorted out:  science vs. religion,[2] objective vs. subjective, knowledge vs. belief, humanity vs. technology…. But now all these opposites are blurring together in a subjective vortex while non-human intelligence looks on and comments about it.

Brave New World, indeed. How shall we respond to it?

More next time.

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


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.


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

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.”

More next time.

Mirror, Mirror, on the Wall…

mirror mirror

“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.

“The common notion [is] 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.’”

The Self Illusion:  How the Social Brain Creates Identity, Bruce Hood[1] (2012)

The idea that we are a self riding through life in a body is deeply ingrained in western thinking. Descartes gets most of the credit for it, but its religious and philosophical roots are much more ancient. (The same is true of the eastern, Buddhist idea that there’s no such a thing as a self. We’ll talk origins another time.)

Descartes’ dualism has the curious effect of excusing us from thinking too closely about what we mean by it. It does this by locating the body in the physical, biological, natural world while placing the self in a transcendent realm that parallels the natural world but remains apart from it. The body, along with the rest of the natural world, is the proper subject of scientific inquiry, but the self and its ethereal realm remain inscrutable, the province of faith and metaphor, religion and the humanities. David P. Barash[2] captures the implications of this dichotomy in Through a Glass Brightly:  Using Science to See Our Species as We Really Are (2018):

“Science differs from theology and the humanities in that it is made to be improved on and corrected over time… By contrast, few theologians, or fundamentalist religious believers of any stripe, are likely to look kindly on ‘revelations’ that suggest corrections to their sacred texts. In 1768, Baron d’Holbach, a major figure in the French Enlightenment, had great fun with this. In his satire Portable Theology (written under the pen name Abbe Bernier, to hide from the censors), d’Holbach defined Religious Doctrine as ‘what every good Christian must believe or else be burned, be it in this world or the next. The dogmas of the Christian religion are immutable decrees of God, who cannot change His mind except when the Church does.’

“By contrast, science not only is open to improvement and modifications but also is to a large extent defined by this openness. Whereas religious practitioners who deviate from their traditions are liable to be derogated — and sometimes killed — for this apostasy …, science thrives on correction and adjustment, aiming not to enshrine received wisdom and tradition but to move its insights closer to correspondence with reality as found in the natural world.”

Attempts to bridge the realms of body and soul end up in pseudo-science, eventually discredited and often silly. Consider for example the ether (or sometimes “aether”) — a term that since Plato and Aristotle has been applied to both the rarefied air only the gods can breathe and the stuff light moves through in inter-stellar space.[3]

You don’t need to be a poet or or prophet to think the self is inviolate. It’s just so obvious to most of us that there’s a self inside who watches and knows all about us — who in fact is us. We experience it as that never-silent internal voice — observing and commenting, often critiquing, sometimes shaming — that always seems to be accurate. We’ve been hearing it for as long as we can remember:  it’s embedded in our brain’s memory banks, all the way back to when we first started remembering things and using language to describe and record them.

We have always been aware that we are aware:
we don’t just observe, we observe ourselves observing.

Hence the belief that we are body and soul seems not worth challenging. Which is why, in keeping with this blog’s purpose, we’re going to do precisely that.

Cartesian dualism is foundational to self-awareness and to our cultural beliefs and institutions. It guides everything from religious faith to criminal culpability, health and wellbeing to mental illness. And so much more. As a result, taking a closer look will not only challenge our perceptions of what it real, it will shake reality itself. This inquiry won’t be easy. Again from The Self Illusion:

“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.

“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.”

That’s where we going. Hang tight.
