BUNDLE: Identity problems (1)

What’s Been Studied

We have seen what causes people to have a unified personal identity. We’ve also looked at the parts of the mind.  We can use this knowledge to look deeper into the construction of identity.  Under the rock of unified identity there are some interesting problems crawling around.

The Three Problems.

The consciousness theorists glibly divide their studies into a Hard Problem (subjectivity) and an Easy Problem (everything else). Identity studies, in contrast, are often divided according to the time scale involved.  Table 1 shows a division of analysis into three parts: longer term continuity, shorter term coherence, and multiplicity. These divisions are often seen in the literature about the origins and significance of personal identity.

The problem that we addressed in the UNITY chapter is the maintenance of longer term cohesion, which we might call the Lifetime Problem. This was the problem posed so clearly by John Locke, and then Thomas Reid, with his example of the callow youth, young lieutenant, and old general, all the same person.  When we talk about the person, their personality, or their true self we are in the territory of the Lifetime Problem.

The Right Now Problem is about shorter term coherence of personality.  We take as granted that at any one time in our consciousness that is happening happens to a single person, ourself.  This happens on the “thin moment of the present” time scale of the perceiving self, fed by the Self’s body-grounded senses of agency and ownership. However, for identity there is something more, an immediate sense, not just that “I am”, but “who I am (right now).”

The first two problems have technical names: diachronic (across time) and synchronic (at one time) identity. The third problem might be called the Plural Problem. We can seem, within ourselves and to others, to have multiple identities. These come and go on different time scales.  Different identities may overlap or alternate in time, compete or coexist.  Some identities can be stronger or more intense.  Multiplicity can vary: from mundane normality (such as playing different social roles or having imaginary playmates) to shocking pathology (dissociative identity disorder). The existence of multiplicity gives real spice to how we understand “who I am (right now)”.

The Lifetime Problem.

The Lifetime Problem of Identity, as we saw in the UNITY chapter, is fairly well understood.  Biological boundaries and our social environment are ultimately responsible for the coherence of a personal identity over one’s lifetime.  Throughout life we retain the material boundaries of body, brain and immune system, while social contacts and institutions reinforce our history to make us a particular social being. The Lifetime Problem is “easy”, but only in the analytic sense that we have access to the information needed to study it: the observations of others and of oneself about oneself.  It’s not like the social scientists, psychologists, philosophers and others haven’t fought over both theories and evidence since the time of John Locke.

Nor is it easy in terms of managing one’s life. First of all, far too many people find that maintaining an identity is a struggle against marginalizing prejudice and oppression. The magnitude and scope of this problem is such that, in the late twentieth century, schools of social criticism pronounced a coherent identity to be impossible, destroyed by power structures and the impotence of language itself.

Even for the more privileged in the world, life transitions such as graduation or parenthood are sometimes actual, problematic transitions and not just the next step. Secondly, in our current culture lots of us often need to or want to reinvent ourselves. After a mess of some kind, we may need to start over.  Or we might be lucky enough to have means and opportunities to, for instance, have a second career, or even a sequence or parallel collection of short-lived careers.  The old “modernist” industrial treadmill of one life trajectory no longer binds us, and, necessarily, no longer leads to a single lifetime identity.

Walkabout

Researchers have recently turned their attention to understanding mind wandering.  This is a mental activity that occupies some 2/3 of our conscious time.  Hundreds of times a day we involuntarily turn our mental attention from our outside surroundings or current task and start to mentally meander.  Sometimes a wander is a minor interruption from which we return to a more focused kind of thought.  Often it is reflections on our past, present, or future that may ultimately change how we behave. And for a few people a wandering mind can be pathologically diverting from real life. But the main and normal function is now believed to be knitting together pieces of our memories and imaginings, creating, in our friend T. Metzinger’s words[1],an “adaptive form of self-deception, namely, an illusion of personal identity across time.”

So for Metzinger and others mind wandering is the Right Now mental activity that solves the Lifetime Problem for us.  It’s our bridge between the present moment and our need for a continuous, cohesive identity.  We should perhaps consider it as the core activity of the narrative self.  We shall learn more later about how mind wandering fits in the spectrum of conscious states.

The Right Now Problem.

“The only Existence, of which we are certain, are Perceptions. … I never can catch myself at any Time without a Perception, and never can observe any Thing but the Perception … I may venture to affirm of the rest of Mankind, that they are nothing but a Bundle of Perceptions … ” David Hume[2], 1745

Identity’s Right Now problem perhaps began with David Hume reducing the self to a structureless bundle of perceptions.  He seems, posthumously, to have triumphed.  If there is any substantial consensus in the study of the conscious self, it is what is commonly referred to as “bundle theory” (honoring Hume).  As we have seen, experts say today that our minds are just a bubbling stew of disconnected, competing functions and mechanisms, adding up to an illusion like the Great Oz behind the curtain.  So you could say that bundle theory leads to the belief that the conscious self is an illusion. IF bundle theory THEN illusory self.

But what actually was behind that curtain?  In the Wizard of Oz, it was a man, a coherent and purposeful, if goofy, particular agent.  He had a life story.  Intuitively you might think that whether or not the self is an illusion, personal identity is a different kind of thing to understand, and it has its own properties and reality. Experts tend to agree – those who focus on the Self tend not to talk about identity, and vice-versa.  Nevertheless, the Right Now Problem of identity has a lot of overlap with study of the self and consciousness because they both are focused on the present moment.

Thus ideas we have already seen — being the agent of ones actions, ownership of ones body and perceptions, and the first person point of view — are important for understanding the internal sense of identity.  These are what give us the feeling of being a particular someone, a single coherent entity, at any given time.

The influence of bundle theory has also led research to focus instead on lower level issues: why there is (A) only one consciousness (B) with the illusion of a now, a present moment.  The estimable Thomas Metzinger calls these the one world problem and the now problem. You might have noticed that philosophers prize Problems over money.

The answers to these are being sought by research into brain activity happening during conscious experiences.  I mentioned gamma band synchrony before in connection with meditation.  Researchers have studied rhythmic synchrony (like the gamma band), other kinds of synchrony such as simultaneous activation of multiple broad brain regions, and exotic measures of the complexity of brain activity.  These are all taken to be “neural correlates”: brain measures that occur at the same time as conscious events and thus underly or explain those events.  There are quite a few theories[3] that try to explain how the mechanisms of these neural events account for features such as the unity of conscious experience or the sense of now-ness and the passage of time.  However, no clear winner has emerged.

So for the Right Now Problem of Identity we have two lines of investigation.  We can look at the neuroscience about the present, unitary conscious moment.  We can also look at psychological studies of agency and ownership.  You might say that these emphasize the “right now” part of “who I am right now.”  We shall come back to how to approach the “who I am” later.

The Plural Problem.

‘Dear, dear! How queer everything is to-day! And yesterday things went on just as usual. I wonder if I’ve been changed in the night? Let me think: was I the same when I got up this morning? I almost think I can remember feeling a little different. But if I’m not the same, the next question is, Who in the world am I? Ah, THAT’S the great puzzle!’  – Alice, speaking from Wonderland

The Oxford don Charles Dodgson must have read the previous century’s philosophical arguments about identity depending on memory.  His character Alice was often confused about who she was, and the word “remember” appears 21 times in Alice’s Adventures in Wonderland[4].  Dodgson himself seems to have felt a deep divide between being a popular writer and being an unhappy mathematician.  He also juggled being a reluctant Anglican deacon, a noted photographer, a casual inventor, a love poet without any obvious lover, and — in his words — “a vile and worthless sinner”, whatever that might have meant.

We all have our divisions.  Some of us are different people when we’re hungry and when we’ve eaten. Many of us have conflicts between social roles, like Lewis Carroll/Charles Dodgson.  Our conflicts can also be between current and future selves.  A few people lead such extraordinary or difficult lives that Arya Starck in The Game of Thrones saga might seem like at most a caricature for them.

The Plural Problem (last row in Table 1) is about accounting for all these different selves.  It tends to be the province of psychologists, psychiatrists, and people who share their orientation.  Consider that a recent encyclopedic history[5] of the idea of self and personal identity, written by two philosophers, has only a few lines about multiple personalities, and a few pages out of 380 about plurality of selves.

Plurality gets studied as a side effect of psychological curiosity about why we do what we do.  Over and over, new theories come up that try to account for the maddening inconsistency of our behavior.  America may be the home of rugged individualism, but it was two American philosophers, William James and George Herbert Mead, who brought the world’s attention to the now-obvious fact that we get nearly all of our identity from interaction with other people.  It was the philosophical interest in this kind of stuff that spun off the fields of psychology and sociology.  Indeed, James was also an early psychologist and Mead an early sociologist.

Since their beginnings in the early twentieth century, the two fields have struggled to find the right scientific methods.  How do you find a parsimonious explanation of the bewildering variety of our behavior and, even more challenging — the contradictions inherent therein?  The models that have been willing to tackle that problem have usually had some flavor of identity plurality in them.

“Life is a cabaret, old chum” — Cabaret, 1966

The song, Cabaret, has had many interpretations, but the broadest is that life is bittersweet and is like a stage production.  The musical came 10 years after the seminal dramaturgical theory[6] of the self from Erving Goffman.  He explained our playing of social roles with (you guessed it) an extended theatrical metaphor, in which we behave front stage, back stage, and off stage to make impressions on our social audience that harmonize with the roles they expect of us.  Even 60 years later this view of self presentation permeates culture, with Facebook, selfies, and personal “branding” expanding our opportunities to be “on stage.”

Goffman emphasized the self’s attempt to influence the other.  But much earlier a peer of James and Mead, Charles Horton Cooley, theorized[7] that we are in fact molded by how we imagine that others see us.  He called this the “looking glass self” because, although others are involved they don’t so much tell us directly what we ought to be. Instead we tell ourselves, based on our imaginative interpretation of what the others expect (remember his “I am what I think that you think I am”).  This is a subtle and nuanced idea for its time, early in the history of social science.

The latter half of the twentieth century was spent working out the details of these social connections that make each of us such a multifaceted person.  A lot of this development clung to the idea of a core or true self and how our multiple roles derived from, or interfered with, that central part.  We were integrated or fragmented, authentic or counterfeit, rational or automatic.  Some theorists emphasized developmental stages with major changes in our lifespan.  This was plurality where a single self held sway during a stage.  True plurality (multiple selves coexisting or alternating over a shorter time frame) would then occur in transitions between stages, when the new you and the old you were fighting it out.

Eventually, leading up to now, researchers started attributing divisions in self more to divisions in the underlying mind, as we have seen.  However, interest in plurality also cropped up from two other directions.

The first of these was microeconomics.  It started out with models of ideally rational behavior of individuals but these were found to be simplistic. Better models took into account the fact that we have conflicts behind our decisions.  Perhaps the first notice of or impetus for this work was an influential essay from Nobel economist Thomas Schelling.  He contributed this scientific insight to the erudite readers of the Journal of Political Economy back in 1961[8]: “… everybody behaves like two people, one who wants clean lungs and long life and another who adores tobacco, or one who wants a lean body and another who wants dessert.”  It came to be understood that these types of conflicts are between our immediate self (Kahneman’s experiencing self, the I*) and our longer-term self (Kahneman’s remembering, narrating, planning self, the Me*). Theorists took special notice of one self’s tricks to force “self control” on the other self.  This would include locking up the booze, or the cigs, or the potato chips, or the gun. In our house the chocolate gets stashed in the fridge crisper along with the lettuce and parsley.  There’s also the dodge of mailing yourself the smartphone to keep it away for a while. Or let somebody else do the policing: send the kid to boarding or military school; tax tobacco.

The other plurality-emphasizing movement came from depth psychology: Carl Jung and the Jungians in particular.  These theorists saw the conflicts within us not as due to social expectations, economic dilemmas, split brains, or (we’ll see this later) unconscious priming.  No, they attribute it to a mysterious shared unconscious full of mythical archetypes.  Different archetypes can compete to take over consciousness.  Jungian theory gradually became to be seen as non-scientific, but a valuable tool in a certain type of psychoanalysis.

In the 90’s a new theory came along, focused completely on plurality, that seemed to have a bit of all preceding theories in it.  Dialogical Self Theory (DST) proposes that each a human mind consists of multiple “self-positions” that act as semi-independent agents.  Some self positions are internalized versions of specific outside parties such as significant others.  Other self positions may be thought of as originating internally and include traditional social roles (son of my father, church goer, artist, soldier) and even points of view or interests (rock’n‘roll fan, foody).  These positions are “dialogical” in the sense that they each have a voice inside your head, and will engage in dialog with some of the other self positions.

DST has been used mainly for psychotherapy.  It uses questioning techniques designed to uncover self positions, and then works to externalize their dialogs so that issues and conflicts can be processed in a therapeutic setting.  When DST came along there had been two decades of strong interest in something called multiple personality disorder.  A backlash was underway, with therapists being sued for apparently promoting the creation of multiple personalities.  DST seems to be a way to accept a therapist’s ability to promote either the uncovering or creation of multiple subselves as a positive goal.  But you can also see echos of other theories.  The self-positions talk to each other like characters in a play (Goffman’s dramaturgical theory, narrative self); external characters are internalized (Williamm James, George H. Mead, Cooley’s Looking Glass Self, and many others); internal conflict (the microeconomics theorists, Jungians and many others); and there are multiple, sometimes archetypal, internal voices (Jungians).

There is very little research on DST, though its adherents would like that to happen. It appears to have some grassroots appeal to lay and self-taught therapists. We shall see later that it has been used in a cultural anthropology context to explain people who believe that they engage in “shape-shifting.”

The founders of DST acknowledge the influence of Mikhail Bakhtin, Russian philosopher, semioticist and literary critic.  They cite Bakhtin’s analysis of literary “polyphony” in which an author actually has, within particular work, multiple voices as an author, but embedded in his character creations.  This hearkens back to Shakespeare’s use of sixth order Theory of Mind intentionality in his plays.  Presumably we would have to go up to seventh order for some works (”Dostoevksy envisions that the reader must understand that Raskolnikov believes <in the truth of some narrative chain of points of view> …”).

There is a lot more to say about plurality. There are many kinds of plurality, some are obscure but not always that rare. Some of these aspects of self are claimed to come from that invisible reservoir, the unconscious, but this can happen in different ways.  Later chapters will dig deeper.  But next we need to introduce what might be considered a neglected problem of personal identity, related to plurality and quite likely caused by the late death of the Self.

MIND: Identity rides this horse (3)

Inside and Underside

Inside of a person it’s too dark to read. — after Mark Twain

There is another realm of perception — that of internal (bodily) perception.  On our mind map  (Figure 1) internal perception (in purple) is a gateway connecting the conscious Ego Tunnel with bodily events in the unconscious realm.  Philosophers are interested in our internal events because they long believed that, compared to our perception of the outside world, internal perceptions are special and thus contribute to our gaining and retaining a sense of self.

mindmodelV02

Figure 1: Map of the Embedded Mind

There’s a paradox here.  Even if you were a “philosophical zombie” (behaving like a person but with no sense of self), you would still have a rich inner life because of all the bodily sensations that you have.  But what is special about them is that (to yourself) they are so clearly yours and yours alone.  Nobody else has the itch that you are currently feeling.  Nobody else feels that particular stomach grumble, heart beat, knee pain, nausea, or dizziness.  Nobody else can use your muscles to guide your finger to your nose with your eyes closed.

This knowledge is an instance of the philosophical notion that there are some first person things we cannot be wrong about.  The philosophers say that we can’t be wrong about who we refer to when we say “I believe”, “I am” or “I feel”.  We might be wrong about the truth of a belief itself (such as “Climate change is a Chinese hoax”), or be deluded about some quality that we think we have (”Trust me, I’m like a smart person.”)  But we can’t be wrong about the fact that we are talking about ourselves, that we believe a thing.  Philosophers call this principle “immunity to error through misidentification”.  That is a truly awkward phrasing.  Even they are glad to shorten it to “IEM”, because they like to talk about it a lot.

Some things that our body knows and deals with may never rise to consciousness: that we need more blood flow, more glycogen dumped from the liver, more digestive acids, and other stuff that just keeps the human animal running.  If you went to school in the twentieth century, this was called maintaining homeostasis, a steady state. The idea that life needed a steady state was, in a way, a reflection of the needs for stability that we had in that turbulent century.  Now in the twenty-first we are all about finding and pushing our limits. We only have some inkling of these unconscious processes if we are exceeding our operating specifications.  Such excess can happen, for example, because of disease or because of some cheerleading (”Go! Do something unusual or hard to prove how good you are.”) from the conscious mind.  So a big dessert after a plenty big meal might have you tasting excess stomach acid.  A marathon makes you feel, rightly, that all the glycogen is gone, and that your heart couldn’t possibly pump any faster.  We push beyond homeostasis, and automatic processes can rise to consciousness.

There are some other internal things that we just know, as the philosophers say, transparently, without thinking about them.  These include such things as the position of our limbs, whether we are tired or hungry, where we hurt.  These may pop into consciousness or not, depending on our current needs.  If they do, they are IEM, that is, we know they are happening to us and not someone else. We probably don’t start out life knowing this IEM stuff, because for a while it is hard for us to discriminate between what is true of ourselves and what is true of others, particularly our caregivers.  We presumably learn the difference ultimately by observing others, that their reactions to things are different from our own, which leads to us acquiring the above-mentioned theory of mind.  Theorists have noted that knowledge of others might very well contribute to the development of our own sense of self.

In the long run we get quite sophisticated about inferring (or knowing) things about our selves.  These things divide quite nicely, from a philosophical point of view, into agency and ownership.  Agency is the sense that you and you alone have caused something to happen, such as taking a walking step, or heartburn after over-eating.  Ownership is the belief that some attribute (like your having two legs) is, without a doubt, yours and yours alone. These aspects of self knowledge are not always IEM (immune to error about whether they refer to our self), but we tend to think they are because we are so familiar with other aspects, as explained above, that are IEM.  Philosophers currently love to talk about agency and ownership because (1) they are important to our sense of self or personal identity, and (2) the situations where we can get them wrong are ripe for arguments over what they mean.

What would be some examples of getting them wrong?  In terms of errors about agency, people with schizophrenia often say that someone else put a thought in their own mind, or that someone else caused them to believe or even do something. A more everyday occurrence is when those of us who are not psychotic still find a way to blame someone else for our actions.  Doubt about self agency can be more subtle, as when one says or thinks: “Did I just say that (awkward or regrettable utterance) out loud?”

The most commonly known example of error about ownership is the rubber hand illusion.  This illusion, even though it is really quite mind-blowing, can be produced by anyone; you don’t have to be an experimental psychologist.  The illusion pairs the stroking of a subject’s concealed hand with a view of a rubber hand being touched in the same way.  Eventually the subject will feel his own hand being touched when he sees the rubber hand being touched, even though his own hand is NO LONGER being touched.  In effect the subject takes the ownership of the rubber hand to be his own.  We could also say that some things that happen during hypnotism disconnect us from ownership, e.g., of a physical symptom, or an emotional connection to a traumatic memory.

I leave it to the reader to imagine ways in which drunkenness could mess up agency or ownership.  In general, though, agency and ownership tend to work pretty well nearly all the time. I can tell whether I moved my arm or whether the doctor did it while examining me.  So we know what’s us and what’s not.  Some argue that such knowledge is foundational, that without it you would not have the kind of sense of self that you take for granted.  Even the Buddhists, when speaking about[1] the illusory Self, note that one may identify with some mental events as “me” (= agency) or “mine” (= ownership).  What I want to emphasize here is that these everyday things we know about ourselves, and that give us the feeling that “this is me” generally are either directly retrieved from the unconscious or else built on top of knowledge from the unconscious.

Note that if you are not psychotic, drunk or brain-damaged (which is hopefully most of the time), the self knowledge described above is also, according to Quassim Cassam[2], “trivial” because it is so easy to come by.  Cassam notes that philosophers nearly always ignore the kind of self knowledge we really care about, “substantial self knowledge”: that is, a more or less accurate understanding of our own character, limitations and aspirations.  Such knowledge requires mental sophistication and use of information from other people.  We can be very deceived about this.  A person might not know that he is a narcissistic bastard, while others, perhaps many others, do know.   Nearly all of us choose to believe only feedback about our imagined good qualities, throwing anything else into a mental trash can.

Which brings us to the fact that some deficits in our substantial self knowledge are also traceable to the unconscious.  We often feel things or take actions that seem to come from nowhere, because unconscious parts of us suddenly seize control without yielding any awareness about why.  Some people give the Jungian name, the Shadow, to these part/parts of the mind responsible for perplexing bursts of temper or tears.  These parts may have been actively repressed earlier in life.

Another mode of unconscious expression, according to anthropologist Gregory Bateson[3], is our nonverbal communications.  He said that we express though body language and tone of voice things that are not really translatable into words.  While some nonverbals can be feigned by actors or other speech makers, they normally happen without a conscious decision or even awareness.  Thus some expressions of our personal style and feelings, which might otherwise give us self insight, can be obscured from us, and often are perceived only subliminally by others.

We are only hitting the highlights here, so it is time to talk about how things get to be conscious.

Fishing in the Unconscious Reservoir.

“Consciousness … does not appear to itself chopped up in bits.  It is nothing jointed; it flows.  A ‘river’ or a ‘stream’ are the metaphors by which it is most naturally described.” — William James, 1890

William James’s metaphor of a conscious stream is meant to emphasize continuity, how one thing flows into another. He says that we have transitions from one focus of thought to another, but each transition partakes somehow of both the previous and following thought, the net result being absolute subjective continuity.  We noted before that with modern research tools we know that  there are tiny gaps that happen in perceiving and mental processing, but we aren’t aware of those in consciousness.  Therefore James is, once again, correct from his perspective of more than a hundred years ago.

Of course a real stream might have different currents going alongside one another.  Sticking with the stream metaphor, that would allow that we could have two or more thoughts running in parallel.  Can you think about more than one thing at a time?  Not at a conscious level.  You might do more than one thing at a time, but you are doing it by rapidly switching back and forth.  So our prized “multi-tasking” is just an illusion, and, research shows, is neither efficient nor harmless.  Trying to do chores and manage young children “at the same time” is incredibly wearing.  Trying to drive and mess with your phone is a major cause of “accidents.”

Now there’s a paradox here.  The brain has often been described as an enormous parallel processor.  And we know that it does fantastic numbers of things at once, like an octopus with a million arms.  But, consider that we have this commonsense concept about “paying attention”.  Attention is also a longstanding concept in psychology.  What both concepts mean is that at any given time the stream of consciousness has a single directed focus.  Our attention is on one thing at a time, such as: the appearance of the person in front of us, or what they are saying, or how what they are saying relates to what they said before, or how having to listen to them is annoying because we need to get a drink instead.  Note that in the first two examples attention is focused on the Ego Tunnel surface facing the external world.  In the other examples attention is focused on the internally facing surface, the border between consciousness and the unconscious.

“Attention” then is our everyday term for changes in the contents of our single stream of consciousness.   For a while I thought that we could blame the I* for changing attention, like it was some sort of channel changer remote control.  But that gives full control over consciousness to the part that we have described as pure awareness, i.e., an observer only.  Changes of attention are the same thing as changes to the contents of our conscious stream.  If we now sort out how those changes happen, then this long-winded “basic” overview of our simple mind map can come, mercifully, to a conclusion.

The stream of consciousness arises from five main mechanisms.

  • Unconscious mental processes have to take turns getting access to consciousness.
  • Subjectively we see this as shifting of our attention. Sometimes the shift seems volitional and sometimes it seems to be imposed upon us.
  • Memories come into consciousness, sometimes being pushed up from the unconscious and sometimes after a mental effort to find them.
  • We explore the future by imagining it.
  • We annotate our own perceptions and thoughts, adding or extracting meaning that also serves to help future extraction from memory.

So we only have a single stream of thought, more like a water pipe, really, but there’s a lot going on, both in the world around us and in the many parts of our society of mind.  How is it determined which things get into consciousness?  My 2 1/2 year old daughter once said to me, “Daddy, I know everything now.”  That would be us if we knew how consciousness keeps filled up. One natural model would be to suppose that thoughts and perceptions have to compete for access to the stream, based on some criteria.  It feels like a competition at some times (when driving, lost, in fast traffic in the rain with a baby crying in the back seat) more than others (reclining on white sand with a mild breeze and gentle waves rolling in).  But what kinds of mental events would compete?

First of all there are immediate, deliberate decisions.  Following our train of thought, we just naturally decide: to look at something, to listen for something, to say something, to recall a name or what someone said last time we saw them, to memorize a phone number, that it’s time to stop and look for birds, to take a selfie, to … OMG did I leave the water running?

I threw that last one in even though it feels different.  It might be an unconscious warning that somehow finally got access to consciousness.  It instead might be the result of thinking about what you have to do when you return home, which causes some kind of mental spark to jump from the idea of home to the memory of turning on the garden hose.  That spark is not necessarily intentional, but is a bit more than a happy accident, because you are a person who tries to avoid goof-ups.

The unconscious is a huge reservoir of stuff that sometimes becomes conscious. As Galen Strawson said, “The conscious/non-conscious border is both murky and porous.”  We symbolize this by double-headed arrow in our Map.  Some unconscious material emerges (from our conscious perspective) apparently spontaneously.  But it is probably the case that we have a large number of unconscious watchers, each with permission to interrupt consciousness when certain things happen.  This could be a long list, including internal and external perceptual events: sudden loss of balance;  the urge to sneeze; large object approaching fast; hearing your spouse’s voice; bell on the shop door rings. Basically our conscious bell gets rung because of unplanned events related to a whole spectrum of biological drives, emotions, motives and preplanned goals or intentions, all of which live in the unconscious part of the mind.

Other changes to the conscious stream are deliberate, activating dormant parts of the mind to do specific jobs.  You might need to do some arithmetic, or estimate your chances of getting away with something, or make a pizza crust, or type on a keyboard. These mental parts have been variously characterized.  For Minsky they were the utility parts of the society of mind.  Metzinger calls them “virtual organs of consciousness.“ The psychologist Robert Ornstein said they are “small minds” of different types, made up of major and minor abilities and biases.

All of your memory is unconscious until you actually recall something from it.  The act of trying to recall can provide a simple demonstration that conscious thinking is not necessarily done in words.  When you try to recall a name or other word you cannot say the word mentally because you don’t at that time know it.  But in some sense you know about it, as a hole or gap in your knowledge.

Suppose you have an intention of telling someone that the new English teacher’s given name is Myrtle.  You might want to ask Dan if he’s met Myrtle.  Mentally you start to formulate a sentence like, “Have you met the new teacher?”  But you don’t even finish the plan for saying the sentence out loud because you can’t supply her name.  So you try to remember her name, a mental effort that doesn’t use words, but instead is sort of a mental reaching that is associated with thoughts about the missing name.  Maybe you think that the name had an “r” sound, or you can “see” (i.e., recall) her face, or you know where you first met her.  Your conscious mind is doing something like a search engine query, and it somehow knows when the right answer is recalled.  This is because other memories come along with it that confirm the episode in which you learned the name.

Very often we begin with recall of an episodic memory, and then we consciously wander through other memories, exploring the past.  The conscious stream can also be taken over by explorations of the future.  We start to imagine plans and fantasies: how the future might be shaped by actions or events.  We compare this future with the past or present.  Conscious wandering in the past and future is, we think, one of our big adaptive advantages compared to other animals.  But we need our unconscious watchdogs to also take care of the present.  Early humans who were too lost in thought also got “lost” to predation, or walked off a cliff.

There is another category of conscious activity that seems obvious to me, although I have not yet seen it described.  At times when we are experiencing or thinking, we seem to mentally annotate those experiences or thoughts.  We do this by thinking or feeling more deeply about those mental events, perhaps extracting meaningfulness or assigning importance, either of which might change how the “remembering self” has access.

It is probably obvious that any overview of the mind’s structure and function, and certainly this overview, has to be shallow, ruthlessly pruning away sometimes famous material.   For instance, if you were taught Freud or Jung back in the day, you might miss them here. Some important concepts didn’t make the cut yet, but will be developed later if they help with our theme of personal identity.

MIND: Identity rides this horse (2)

The BodyMind

These days the mind is rarely considered in isolation from the body.  Even in science fiction, with mind transplants, uploads, and teleportation, they write about how mind and body are entwined, so that new minds adjust to bodies, or they miss the old bodies.  It’s also true that when people speak about the brain and the mind, it’s a shorthand because what matters is really the whole nervous system.  As time goes on, research has expanded the physical basis of the mind.  We now know that bacteria in your gut can do things like make you want to eat sugar, apparently by affecting the large part of the nervous system in the gut.

So, in Figure 1 we don’t hold body and mind that much apart.  The map has one big beehive shape, the BodyMind, that is their combination.  Its orange outline is more or less the border of the body.  The rest of the diagram is a square-topped shape representing the Outside World.

Within the BodyMind there is the Ego Tunnel, and inside it, all that we are aware of: what the philosophers call the contents of consciousness.  The rest of the BodyMind, outside of the Ego Tunnel, represents the unconscious mind, which is everything from: the sensory organs and their output, to our past stored as memories, and all the other work of the BodyMind of which we are not consciously aware.

Figure 1: Map of the Embedded Mind

The Ego Tunnel’s surface (the blue, wavy line) looks like a border between conscious and unconscious territory, but it’s not just a border.  The Ego Tunnel is also a computational process, our own personal virtual reality generator that consumes some huge fraction of the processing power of our nervous system.  Also, in our visual metaphor, the inside of the Ego Tunnel is part of it, the reason for its existence — the Jamesian Self.  We have talked about the function of its parts before.  Let’s now look into how they fit into the overall holon called the embedded mind.

Metaphors for Me*

Figure 1 shows the I* immersed in/surrounded by the yellow space of the Me*The I* can be focused on things outside of the Self, via the senses, and it can be focused on itself, the Me*.  Some information, such as raw bodily sensations, no doubt flows directly to the I* from the unconscious, but many things observed by the I* are mediated by the self model, the Me*. Anything we say about the Me* is of course just a metaphor.  The Me* is a thing unlike any other, so we struggle to classify or describe it.

The narrative metaphor discussed earlier is helpful, but it’s doubtful that we could push that any further and think of the Me* as a book, even a book that continues to write itself.  People just don’t keep their whole life available to re-examine at any time. At its most reduced the metaphor would be something like Dennett’s “center of narrative gravity.”  But Dennett is a contrarian.  This is just one of his ways of saying that consciousness doesn’t really exist as a thing, that there is nothing about it that we need to explain, that there’s no Hard Problem of Consciousness.

Another powerful metaphor for the Me* is that of a model or simulation, as proposed by Metzinger.  Either term has the sense of something that stands for something else by virtue of simplifying it.  Prior to the digital age, use of either “model” or “simulation” would have meant that the simplification was rather extreme.  Even a mathematical simulation would lack dynamism and detail.  These days, however, computation allows us to simulate something to an astonishing degree of likeness, and our thinkers routinely imagine simulations of alternate realities as being possible.  So a simulation implies the dynamism that is lacking in a narrative.

But wait a minute — if you simulate part of the Self, what is the thing being simulated?  It can’t be some Self that is more real.  Philosophy’s usual answer to that question is that the simulation is of “what it is like (remember Nagel’s conscious bat from the previous chapter?) to be you.”  This still sounds circular: the Self is a simulation of the Self?  That’s why it always seems so helpful to say that there is an I*, which at least gives us something that is aware of the simulation.

Further understanding the functioning of the Ego Tunnel needs to consider what is outside the Tunnel and how it gets into consciousness.  Let’s turn to what is outside the Ego Tunnel’s border, a border that is, according to Galen Strawson “both murky and porous.”  As our diagram shows, there are two realms outside the Ego Tunnel: the outside world and the internal, unconscious mind.

Perception and Sociality.

Figure 1 shows perceptual processing, largely automatic and unconscious, as the gateway through which the simulation of the outside world arrives into the Ego Tunnel.  As we have seen, crisp and live as that world seems, it is only a model, poor in detail, with invisible gaps.  I have been hearing that refrain since my college psych courses, but always I (actually, my Me*) thought, ‘So what, it works well enough and any goofs (illusions) that it makes are just curiosities.’  The reality behind this unreal simulation is something else, however.  First of all, quantum theory completely destroys the solidity of the outside world.  All those particles that make up our illusory environment are continually forking into different parts of the multiverse as their wave functions collapse.

Suppose you shrug off the idea of quantum theory as being reality’s clown suit, and assume that the body of reality somehow stands naked and exposed to us. There is still gobs of evidence that we see and hear and feel things that aren’t there, yet not some things that are there.  Our abilities are designed to maintain the illusion of a stable outside world, even though the raw data we start with represent only bits and pieces of that world.  We all know about the visual blind spot, but we never see it.  Our eyes continually make tiny movements, but we never are aware of it.  When we scan across a scene our minds fill in the gaps between the images seen at the beginning and end of a scan.  The fine detail of the world’s visual appearance is only there for focal vision.  Peripheral vision is an entirely different, lower resolution simulation, but we believe that it and the focal world are continuous, one and the same.  We finely discriminate colors when they are side by side, but can’t identify them later in a line-up.  The same color perception can be caused by different combinations of light wavelengths.

There is a theory, called critical realism, that evolution has forced us to evolve senses that accurately model the outside world, because how else would we find our food and mates, and escape danger.  This theory is being replaced by one based on a mathematical proof[1] that what matters is identifying something more quickly while expending less energy to do it.  That would mean that we would evolve perception that matches reality only if reality was already structured in a way that meets our needs.  Most of us do not think that the universe was designed in some way that favors human beings over trees or rocks.  Therefore it’s most likely that we are perceiving the world in our species’ own quirky ways.  This is nature’s way.  For my dog, half of the world is food and the rest is a parking lot.

The model in Figure 1 does suggest that, for our minds, other people are as important, or more so, than is the rest of the outside world. Like other social species, our senses are tuned to immediately pick out and identify our conspecifics from an early age.  When we are touched by another person it lights up a different part of the brain than other touches do.  Robin Dunbar, a primatologist, popularized the notion[2] that we have big brains because they are needed to deal with the complex soap opera called other people.  He also looked at neocortex size in primates and found that it correlated with the size of their social networks.  For humans the number is 150, which pops up all over the place, from hunter-gatherer clans to army companies, to the number of people with whom we can maintain personal relationships.  Dunbar and others then looked at levels of social intimacy and found that, starting with an inner clique of 5 best friends, the sizes of our expanding social circles increase by a factor of 3 as levels of intimacy decrease.  This is shown on our Map as concentric arcs in the social environment.

As a onetime primatologist, my heart is warmed by the fact that Dunbar (who did his thesis on the Gelada baboon at the same time that I was studying rhesus monkeys) using primate data, contributed perhaps the most widely known quantitative theory in all of social and psychological science.  But he went further than that, all the way out to philosophy, when incorporating the concept called Levels of Intentionality.  We know that a child first realizes at age 4 that other people have their own mental states.  We say that the child now has a Theory of Mind (ToM), meaning that the child believes that other people have mental states as well.

Philosophers such as John Searle say that some subjective (mental) states are directed to the outside world, creating a relationship between us and that world called intentionality.  There are levels of intentionality, denoted by how many such relationships hold simultaneously.  A child may have a theory of mind about her doll with whom she is having tea.  This is level two: she thinks (level one) that her doll likes (level two) tea .  Dunbar thinks that many animals have level one (they believe something, or intend something); some might have level two.  So how far can this levels business go?  Listen to Dunbar as he describes the magic of storytelling.  Count the italicized verbs to follow the levels.

  1. “… the audience must understand that Iago intends that Othello believes that his wife Desdemona wants to run off with Cassio (which would probably not be much more than idle fantasy by Desdemona were Iago not able to convince Othello that Cassio himself also wanted the same outcome) … if they also have to factor Cassio’s complicity into the equation to make the deception convincing for Othello, the audience has to be able to work at fifth order intentionality.  But to do this, Shakespeare himself must operate at one level higher: he must intend that the audience understands …etc.  Shakespeare was having to work comfortably at sixth order intentionality, and this is now one level beyond the normal limits for most adult humans. “

So now we know one more way in which Shakespeare was a brainiac.  Dunbar and others emphasize the cognitive processing power (hence bigger brains) that is needed for higher order intentionality. Hence bigger brains exist.  In primates, relative neocortex size correlates with social group size and other social behavior measures.   But is all that work being done consciously, i.e. by the Me*?  Perhaps not.  Metzinger and others have noted that many things we perceive about other people happen immediately, like other, seemingly simpler, perceptions that don’t require conscious thought.  The standard example of simple perception comes from philosophers, who nearly always cite seeing and touching a book in front of them. One can only wonder why they pick that example.  On the other hand your brain can heat to the smoke point when figuring out the maddeningly subtle and indirect intentionality of the characters in a John LeCarre’ novel.

So in our Map, “sensory processing” is part of the unconscious part of the mind.  We recognize birds, books, smiles and eye contact without thinking. Indeed it’s likely that all body language and other nonverbal communication is usually below the level of conscious notice entirely.  Higher level social impressions, such as any exchange involving conversation, require some conscious reflection to be understood.  Much to do with our personal identity involves higher order intentionality, as in the sociologist Charles H. Cooley’s concept of the Looking Glass Self.  There are 4 levels (just count the verbs) in his prototypical statement about social influence:

“I am what I think that you think I am.”  Charles Horton Cooley, Human Nature and the Social Order, 1902.

MIND: Identity rides this horse (1)

The Mind Map

Personal identity rides the mind.  The mind rides the brain.  The brain rides the body (surprised you there?).  The body rides whatever conveyance (horse, skateboard, car) that the identity chooses.  So it’s not riding “all the way down”, as the old joke goes.  However, the joke is about the concept of nested  levels of organization.  That concept is a powerful aid to understanding, especially when we think of holons.  A holon is a whole, made of parts whose integration into the whole creates an entirely different thing from the parts.  And of course every part is also a holon made of other parts. So it really is holons “all the way down”. What makes this so useful is what Ken Wilber claims: anything that exists or that you can name is a holon.   We are interested in personal identity.  I can summarize a lot of esoterica by stating that a personal identity is a holon made up of a human organism and a mind, embedded in a multi-layered social system.

But what’s a mind made of?  What are mind parts?  The previous chapter on the durability of personal identity made a start in naming some key parts of the mind.  But if we want to understand identity, and its most mysterious and intriguing part, indeed the very horse it rides, is a mind, then we need to know what’s included in a mind and how it all fits together.  Any solid concepts that we find could help later when talking about current and future changes to identities, and to what extent a person might have more than one.

Actually attempting to map the parts of the mind in public like this is risky because it is contested territory; the authorities, experts all, agree to disagree.  The risks might not be like walking in the proverbial mine field, but they are like walking in a dog park where the canines themselves are in charge of cleaning up: messy and likely to be embarrassing.  Still, we are engaged in chimerealism, so let’s get to it.

mindmodelV02

Figure 1: Map of the Embedded Mind

Behold Figure 1, a diagram of the holon called embedded mind.  It’s jam packed with concepts that we are going to need.  To some people it will be scary looking, having too much going on at once.  But consider it to be a map.  We can all read maps.

Our map is a necessarily simplistic guide to the territory called mind.  It’s also a way to anchor a vocabulary that will allow us to explore that territory in detail without having to deal with so much of the technical language used by the sciences and philosophy of the mind.   The map refers to models made by different experts with various purposes, so some things that might be implied by it will doubtless be wrong, or in expert eyes, incompatible.  And, as us nerds sometimes say, wrong for multiple values of wrong.  However, like any good map, it is replete with interesting places to stop off and visit.

What’s in Your Ego Tunnel?

Let’s start in the middle. There’s a circle made of a wavy blue line.  This is the surface of Thomas Metzinger’s Ego Tunnel[1].  Each one of us is enclosed inside of our own simulation of reality, which Metzinger likens to a tunnel, because all that we experience is confined to that tunnel. It’s as if we are moving through the tunnel while over time our experience changes. He might have picked another metaphor: a jail cell (too restrictive) or a cave, but that’s Plato’s metaphor and so might be confusing.  Metzinger implies that the walls of the tunnel (the “surface” in the diagram) are like a movie screen upon which our model of reality appears.  But to whom does it appear?  In the last chapter we called it “the “I”, a term that goes back to William James.  But something like it has been called other things, including the ego, the illusory self, and pure awareness.  Let’s call it the I* (think “eye-star”) just to keep it distinct. The I* in Figure 1 is a gray oval, but we think that it doesn’t have any real physical boundaries.  Research says that it is not a fixed part of the brain, but some kind of fluid, ever-changing process that provides us the illusion of a point of view.

Thinking about that “point of view” can lead us back to misunderstanding.  The error goes all the way back to Rene’ Descartes, who said that someone must be perceiving what our senses bring into the mind.  He described the perceiver as a homunculus, a little man inside your head.  Now generations of college students have been told that old Rene’ was dead wrong, because how could the homunculus perceive anything unless it had another homunculus inside it?  And then what about the third little person inside the second one, and so on “all the way down”?  The problem is that once we walk out of the classroom our experience says that someone is home inside of us, that we have, or are, a Self.  So all the philosophy and research disproving the existence of a self is hard to grasp, to put it mildly.

Some who hold to the illusory self theory still find the I*/Me distinction useful, where the I* is the pure, moment-to-moment awareness and the Me* is the observed, ongoing content of our internal lives. Let’s call it the “Jamesian Self” model, since William James stated the modern version of it[2].  There is supporting evidence for it from a number of directions.

Self Talk.

There’s a hint about the Jamesian Self in everyday life. Sam Harris reminds us that we talk to ourselves.  He notes that once children start to gain language, we hear them engaging in long monologues. The function of this might be to practice speaking out loud, but to whom are they speaking?  One possibility is imaginary friends, a subject to which we shall return later.  For now it’s worth asking, what would be the beginning of an imaginary friend except some part of your Self?

Talking to yourself, out loud or not, is common enough throughout life.  You might announce, that “I found it!”, “That was tasty”, or “I need to get going.”  If in fact someone else hears us, we can be somewhat embarrassed, depending on what was said and whether we know the hearer.  These announcements seem to be part of a private conversation.  Could it be the I* talking to the Me*? No, we have assumed that the I* is a pure observer, so it is mute. Maybe “self talk” is the Me* reporting to the I*.  This is all bound up somehow with what we know from people with split brains, that language issues from the left hemisphere.  That also is a story for later.

Meditation Can Isolate the I*.

And every morning we are chased out of bed by our thoughts. — Sam Harris, Waking Up.

Sam Harris has pointed out that the traditional rationales for meditation often come with medium to huge doses of religious ornamentation, but that the practice of meditation, while difficult, gives reproducible results.  Internally its goal, and its result when successful, is the isolation of awareness itself (the I*) from the thoughts and perceptions (the Me*) of which we are aware.  Meditation has externally measurable effects on brain function and body physiology.  Meditators have been in great demand by researchers for years now, as serious (”respectable”) interest in consciousness swelled like some kind of economic bubble.

Research has found that meditators produce strong oscillations in their gamma band brain waves.  These waves apparently reflect how the brain synchronizes data coming in from different senses with slightly different delays.  In that way it can put together information to meld sensations together, so that, for example you would both hear someone talking and see their mouth moving at the same apparent time.  The intensity of these waves is higher when meditators think that their meditation is deeper.  So perhaps gamma band synchrony is a big part of the moment to moment perceiving I*.  Studying meditators allows scientists to see the synchrony.  Outside of meditation, the brain activity of the ever busy, chattering Me* probably obscures our ability to externally measure the simpler process of the I*.

The lore of meditation says that there are levels at which the practitioner starts to perceive the universe directly, as a kind of ultimate reality.  This goes beyond our scientific understanding at this time.  Nothing we know from external study would suggest that the brain, no matter how synchronized its internal workings might get, would be able to sense anything except through the sensory equipment (eyes, ears and so on) that we all agree that we have.  Thus current mainstream theory sees no way for us to bypass those senses and “get under the skin” of reality to perceive it more like it “really is.”  The same unanswered question applies to some experiences from psychedelic drugs.

There are of course plenty of thinkers who already offer explanations, and perhaps some of these will provide a spark to work on a new consensus when mainstream science and philosophy become ready to tackle the next level. On the other hand, maybe the final understanding will somehow derive without destroying the current consensus.  The current Dalai Lama, who might be said to speak for meditators in the same way that the Pope speaks for pray-ers, has said out loud, in public, that maybe even the highest forms of consciousness must depend on the physical brain.

The Experiencing and Remembering Selves.

Research from a Nobel prize winner in Economics is a surprise fit to the theory of a Jamesian Self.  Daniel Kahneman, a cognitive psychologist and not an economist, won the prize in 2002 for work showing that people do not make decisions in the rational, self-interested way that had been assumed by economists.  These days Kahneman gives TED talks[3] about a much bigger topic: how a division between an experiencing self and a remembering self affects how we evaluate all parts of our lives.  This division helps explain many puzzling cognitive biases (thinking and judgement errors) that we all have.  Few researchers have earned the right to have a theory this broad be widely accepted.

Kahneman starts his story with a classic description of the “present moment” aspect of conscious experience.  We know that our sense of what is “now” lasts about 3 seconds.  He dramatically points out that we have about 600 million of these moments in a lifetime and yet there’s a sense in which they all flow away, lost to us like a tear dropped in a river.  As they are happening these moments are apprehended by what he calls the experiencing self.  We may naively think that we remember important ones of these moments as they were at the time, but many experiments show this is not so.

Earlier I wrote about Julian Jaynes showing us graduate students that our simplest memories, such as when we went swimming, were not recalled in a form that reproduced what we actually experienced when we swam.  Kahneman’s theory also says that memory is handled by a remembering self that summarizes what happened in ways that are definitely not the literal truth.

One of his classic studies involves the memory of pain experienced by (voluntary) immersion of a subject’s hand into cold water.  Ina typical study all subjects got a fixed period, say 60 seconds, at a painful temperature of 57 degrees Fahrenheit.  This period was continuous with another 30 seconds during which (unknown to them) the water had been warmed slightly, to 59 degrees. Half the subjects had the warmer period at the beginning, and half at the end.  Only 7 minutes later all were asked which part of the experiment they would be more willing to repeat.  The idea was that they would be more willing to repeat the part that was remembered as less painful.  Eighty per cent of them preferred to repeat the part that ended with warmer, less painful water.  This is even though both parts, as moment-to-moment experiences had exactly the same amount of time in colder and warmer water.

Kahneman did this and other studies, including ones of a naturally painful medical procedure, to show that, basically, memory is biased to emphasize the more recent experience in an event.  If a painful episode ends with a decrease in discomfort, or even some reward (as when we give a treat to a child or pet who has had to endure an unpleasantness), then the episode will be recalled as less painful than it actually was.  Note that in the cold water study this happened only 7 minutes or 140 “now moments” after the painful experience.

In study after study, the separation between memory and experience seemed to be very strong. Yuval Harari[4],in recounting Kahneman’s theory, prefers to say “narrating self” instead of remembering self, apparently because memory is often likened to story creation.  Harari points out that in our self narration we often create stories of the future.  These are plans, everything from what to do to get the kids in the car, to New Year’s resolutions.  Plans are made by the narrating self, but for them to get executed they have to engage the experiencing self.  As Harari puts it, just as the narrating self cares not for what really happens to the experiencing self, the experiencing self is not bound to the plans of the narrating self.  Thus so many times immediate experience overrules those plans.  We don’t eat the right things or we don’t maintain our cool under stress.

Kahneman’s theory of the experiencing versus remembering selves is based on findings of cognitive biases and failure of plans. There are plenty of other psychological explanations of these, but Kahneman’s theory of the two types of self fits them into a very broad picture.  How much alike are our Jamesian (I/Me) Self theory and Kahneman’s theory?  Certainly the experiencing self seems very much like the I* of pure awareness. Note however that to say the experiencing self cares for something, or “must be engaged” for something to happen, goes beyond an I* of pure awareness.  Still there are philosophers who identify Kahneman’s experiencing self with the I* that is the subjective side of the Jamesian Self.

Before going on to the Me* there is one other tidbit about the I*.  Metzinger actually gave us an evolutionary adaptive reason why the I* needs to be so focused on the present moment.  He says that it’s the present moment that carries information about immediate risk (such as an approaching predator, falling rock, falling stock price).  Therefore we have to be aware that we are in the present moment, and that the moment is more real than “our memories and fantasies” being entertained by the Me*.  So it’s no wonder that Kahneman found that, in a manner of speaking, the I* (experiencing self) does not give a cr*p about anything but right now.

We next have to ask: how does the remembering/narrating self compare to the Me*? To answer this we have to be clear about what aspect of memory is involved.  Our concept of memory includes everything from piano solos to phone numbers to faces and stories of the past.  the Me* is all about episodic memory, which is our ability to recall personal experiences of an autobiographical type; essentially, what happens to us or what we did.

We have been talking about episodic memory when trying to understand Self persistence (previous chapter) and now, self narration.  The Me* is the part of consciousness responsible for the continuing story of our lives.  Therefore the Me* would have to involve the processes of retrieving, using and forming episodic memories.  This is a big part of what Kahneman’s remembering self would have to do. So Kahneman’s theory seems to support the Jamesian Self that we are using in Figure 1.  The I* is his experiencing self, and the Me* has as part of its job what the remembering self does.

(A self disclosure: I just stood up and said out loud, without premeditation: “This is just what I wanted to do.”  Nobody else here but me and the dogs.  To whom or what was my utterance directed?  By whom?)

Split Brains and Narration.

Another strong research program fits the Jamesian Self idea:  five decades of work on people whose brains have been surgically divided in half, the so-called split brain studies.  Those and related studies have shown that on the left side of the brain there is a “left-brain interpreter[5]” that produces narrative interpretations of why new information fits with what a person already knows.  This theory is from Michael Gazzaniga, who helped originate the split-brain research and remains its most important figure.  The interpreter is always on duty when we are awake because new things are always happening.  This sounds like the Me*, and indeed people have identified[6] the interpreter with the increasingly common idea that there is a narrative self[7] that gives our identity continuity by narrating a sort of never-ending story of our lives .

Gazzaniga and others find that the right side of the brain, on the other hand, helps to insure that such interpretations conform more closely to facts than to beliefs, and is necessary for making morally sound interpretations. Most important for the I*/Me distinction, however, is this, from Gazzaniga[8]:

“Our right hemisphere behaves more like the rat’s. It does not try to interpret its experience to find the deeper meaning; it lives only in the thin moment of the present.” (italics added)

This quote suggests that at least a good chunk of the experiencing self occurs in the right hemisphere.  We can’t say that the experiencing self is confined only to the right side because plenty of split brain experiments show the left hemisphere able to report on its experience of sensory events.

Narration as a mechanism of the self seems pretty widely accepted.  For example, the highly regarded and popular philosopher of the mind Daniel Dennett wrote about[9] “The Self as a Center of Narrative Gravity”.  He develops a detailed metaphor that the self is a fictional character, like an ongoing autobiographical novel in your mind.  As one of many these days who say that the self is only an illusion, he likens it to another abstract concept, the center of gravity.  The center of gravity of a worldly object is an abstraction, not as real as the object itself, but nonetheless useful in daily life.  You implicitly calculate a center of gravity when you want to set your coffee cup down near the table edge without the cup tipping over. It’s a center of gravity mistake when you swerve your tall truck to avoid something, and the truck rolls over. Dennett calls the self a narrative center of gravity, in that all your internally generated stories revolve around that imaginary self.

Use of the term, narrative, means we are talking about the realm of language.  In the sciences of the mind it is not totally settled whether you can be conscious without language.  Some of us seem to think mostly in words, while others excel at “visualizing” stories of the past or future.  Steven Pinker says[10], “Consciousness surely does not depend on language. Babies, many animals and patients robbed of speech by brain damage are not insensate robots; they have reactions like ours that indicate that someone’s home.”  However, his examples seem to be about the awareness possessed by the I*.  The Me* is the story-maker.  Pre-verbal infants and animals might be able to create a self narrative without using words, maybe analogous to a stick-figure cartoon with only non-verbal sounds.  Dreaming dogs look and sound like they are doing this.  Our own dreams are often eerily lacking dialog.  For now let’s say that the “language” of consciousness might be in some proportions verbal, pre-verbal or non-verbal.

However, consciousness science has not clearly decided whether the I* is only an observer, as it is when one is meditating, or whether it is also responsible for decisions to act.  I hinted at this when talking about Kahneman’s experiencing self, and how it can cause actions contrary to the plans of the remembering self.  Experts often cite mindfulness meditation as the pure “I”.  But when they talk about controlling action (which the philosophers, as we shall see later, call “agency”) they cite the I* as its source, apparently because action always occurs in some present moment.  But this doesn’t make any sense.  Everything in the conscious self occurs in the present moment; that’s one of the defining characteristics of consciousness.  It makes more sense to stick with the proven existence (via studies on meditation) of the pure awareness that we call I*.  This leaves action/agency to the thinking, narrating, remembering, the Me*, which is processing the information needed to decide about actions.  There are fMRI studies that are starting to localize all these functions in particular parts of the brain.  Hopefully such studies can eventually resolve the question.

It seems clear enough that what we have called the Jamesian Self of the I* and the Me* is pretty well accepted.Before moving on we have to carefully interpret this narrative thing.  Ever since the postmodernist social critics, the word narrative has been applied to many things.  Among those who study the self there are those who think that the self narrative is a life story that we try to keep consistent.  Some say that a self narrative is the only way to live a life of which you would be proud: the old “unexamined life is not worth living” idea.  Skeptics say that neither of these things is true, that, for example, some people live more in the moment, so that their past experiences are only implicit (usually not recalled to memory) in how they affect conduct and thinking. According to the philosopher Galen Strawson[11], people just differ in how much they think about the past. Some critics think that the Me*s narratives are really short, trivial,and disconnected: on the order of, I’m hungry so I should decide what to eat.

For our purposes I think we should be flexible about the scope and continuity of what we think is self narrative.  For different people, or a person at different times, the extent to which they try to connect the present to their overall life story is going to vary.  The hungry person might decide to eat just because, or because there won’t be time later, or because the mood changes from being too hungry have led to regrettable social interactions, or because Dad always said you had to “clean your plate” to the child that you once were, or because food should not be wasted when some people in the world are going hungry.  Our stories may be short and disconnected, or thoughtfully grounded in who we are, or anything in between.  None of these differences seem pertinent to our map of the mind.

In this and the previous chapter we have seen a number of theorists and theories that map well to the Jamesian Self of the I* and the Me*.  Ken Wilber calls an idea that is generally accepted an “orienting generalization”: something that is true enough to use in understanding other things.  Now that we accept the Jamesian Self as an orienting generalization we can keep on filling out our map around that center.

UNITY: Coherence of the manifold self (3)

Material Causes

Aristotle said that explanations should include a material cause. By this he meant whatever substances are needed for a particular event or thing to happen. Suppose I ask the question, ‘What makes you a unitary personality and allows you to persist as a distinct individual?’  Those who are a little science-minded, or a little fond of the obvious, might say: “Well I’m enclosed in this body. It has a boundary between me and the world around it.” Good for you. That is indeed your material cause.

These days we know that our material uniqueness starts with our DNA, which is also becoming the ultimate ID badge. DNA is a necessary cause of individuality. It is not however a sufficient cause, because each of us also have a unique environment that also affects how we develop. Note that regardless of how many writers try to dumb down the concept, DNA is not a “blueprint”. The closest analogy might be a computer program optimized over and over so that each piece of it is used in numerous and interacting ways. Discarded sections are left in but tagged as obsolete. Random parts are repeated and randomly mutated. Then the computer code is run through a compression algorithm to pack it down, and then it’s encrypted. Placed in a sack of nutrients, it somehow unpacks itself, creates its own interpreter, and runs its program, with constant feedback from the environment (the cell, the body, the encompassing society) affecting the execution and indeed modifying, through epigenetics, the program code itself. There’s different outcomes for different tissues, as well, while the random changes to the working interpreters inside our zillions of cells continue throughout life. That’s how not simple DNA is.

So how do we extract our unique identity from the DNA program? The theoretical biologist and Buddhist mystic, Francesco Varela, has perhaps the most poetic account. His concept is called autopoiesis: how living systems self-organize so that the mechanisms of the system are encapsulated in a boundary that is created by those same mechanisms, and the boundary is what enables the system to function. You see the circularity, almost a self-referencing definition there?  Well …it might go down easier with some concrete examples. Varela says that each person has three distinct, but coexistent autopoietic systems: cellular structure, the nervous system, and the immune system. Cells of course have a membrane defining their extent, but they also get together and form the largest organ in the body, the skin. The skin is the bag that holds us together physically and acts as both barrier and transceiver to the outside world. So it clearly is one material cause of our physical integrity and persistence over time.

The second autopoietic system is the immune system. It’s very nature is to define the difference between self and non-self, and to enforce that as necessary. While it uses the body as its boundary, it also is a virtual boundary, repelling or disposing of invaders. It’s like Gandalf telling the Balrog, “You shall not pass!” (If only there was a non-copyrighted image to stick here!)

The third autopoietic system, the nervous system, has the brain as its extremely high-value, high-function core. Your brain is bounded by the cup of the skull as its primary physical protection. It also has a triple outer layer of membranes, as well as a complex of tightly fused cells around most of its blood vessels, the so-called blood-brain barrier. The penetration of these boundaries is necessary for direct computer to brain interfaces. This is why, even though such interfaces have great promise, and indeed are helping people already, most folks of any sense would find them creepy and even frightening.

And the brain does so much more for our integrity and continued existence. It guides our behavior (usually, hopefully) attempting to ensure that we survive and thrive. It also actually constructs the first-person Self — your very “I” that is your phenomenological essence — as part of a brain-made internal model of the perceived and understood world. This model sets us off (yet another boundary) from whatever ineffable cosmic reality it is that actually surrounds us.

So we have these boundaries, and uniquely programmed biological machinery, that preserve some aspects of an enormously complicated physical pattern over our lifetimes. Is this sufficient to take care of our self continuity? Not really. Any vertebrate animal has of the above boundaries. Some might even have the rudiments of a Self. When we think of ourselves as a person having an identity we are talking about much more, including a self concept (the answer to Who am I?) and the above-mentioned first-person conscious point of view. Philosophers have really dug their teeth into persistence of the Self.

Mental Multiplicity

Minds are simply what brains do.-
Marvin Minsky, The Society of Mind

The human brain has a lot to do, and so, therefore, does the mind. Most of it we are not aware of. Oddly, common sense and science disagree on the meaning of these simple statements.

In science we think that the brain, or at least the nervous system: heads up the body’s “automatic” functions like breathing and metabolism, makes the muscles move the body, decides what’s for dinner, has emotions, does math, and everything in between. Most of these numerous functions are only loosely connected to one another. Science also thinks that only some functions are conscious, that there is no real central control, that the conscious self is largely an illusion, and that all of its so-called decisions are actually determined by numerous, non-conscious factors, even before we are aware of making a decision.

On the other hand, people in general, including children and the blind, think that their essence is a disembodied point of existence behind their eyes and between their ears. This starts in early childhood at about the time (age 4) that we start to believe that other people have mental points of view, too. And even long years after we have first started being taught about the brain (age 9), we believe that the brain is a sort of mental multi-tool, there just to help out the real, feeling self which is, metaphorically if not in fact, located in the heart.[What do you think you are?] We say that if you want to make the right decision, you make it with your heart. But regardless, your decisions are your own, in the sense of both your responsibility for them, and in the sense of your conscious self being their primal cause. Bottom line is: folks are native Cartesian dualists but they get that the brain is useful in some vague way.

These days the scientific approach is where we find new understanding of identity. Let’s start breaking the science part down by addressing the “brain has lot to do” thing.

In 1985 the AI scientist Marvin Minsky wrote a book, The Society of Mind, which said that there was no big mystery in what a mind does, because it emerged from a host of simpler parts that he called agents. Each agent accomplished a particular task, but in a simple, mindless way. A mind was the “society” of these agents. Mental activity emerged from their interactions just like life emerges from myriad chemical interactions and structures that are, by themselves, not alive. Thus Minsky proposed a solution to how a mind can emerge from non-mental stuff.

The ancients did not see how a mind could be born out of matter, so they invented the soul. Because a soul was not matter and did not contain any parts, it was not subject to the inevitable decay of matter, and it therefore was eternal. Plato’s formulation of this was so influential that centuries later the Christian church adopted the it as a core belief. The idea has never died, although it is out of favor with virtually all of science and much of philosophy.

Minsky’s formulation was an early example of modern systems-oriented thinking that complexity emerges from the behavior of multiple, quite highly numerous, parts. This is apropos since the brain/mind complex is widely considered to be the most complicated thing of which we know. The Society of Mind was one of the cracks that released a flood of new work on mind and brain that is still with us today.

Just two years before Minsky’s book his philosophical colleague Jerry Fodor, also at MIT, wrote a book, Modularity of Mind. In it Fodor listed nine properties that would be evidence that a function of the mind was “modular”, which meant that, like Minsky’s agents, it was single-purpose and somewhat independent of other modules. The criteria must derive from a computational point of view because seven of them sound like well-known principles of good software design.

Since these two pioneering efforts the explosion of efforts to understand the mind has put a lot of emphasis on identifying its functional parts. Within that work there is intense debate about: How many parts? What are they? How big are they? How connected or independent are they?

On one end is “massive modularity” with lots of special purpose, quite autonomous parts that are presumed to be evolutionary adaptations. An example would be that very new infants have an inbuilt compulsion to look at patterns that resemble a human face. The modularity criteria here are (as in most evolutionary psychology examples) restriction of a function to specific inputs and rigid timing of occurrence in development.

On the other end of a rather fuzzy spectrum might be cognitivists, who emphasize much fewer, higher level mechanisms such as attention, learning, and memory. These lead to creation of conceptual knowledge and the mental construction of beliefs and cognitive biases to guide actions.

There are many and nuanced positions in between these two, but there appears to be a general belief in something like partial functional independence of many parts of the mind, based a variety of observations and experiments. For example, some illusions continue to happen even after the illusion has been explained to someone. So the perceiving part is independent of the understanding part, thus fitting Fodor’s criterion that a module is not guided by information at higher levels.

Other evidence relates to Fodor’s criterion of localization of modules to dedicated neural architecture. We have all heard the stories of bizarre effects from damage to the brain, even though these are rare and sometimes, but not always, one of a kind. Nearly every day there is a new story of some psychological concept being verified by a consistent pattern in the imaging of neural activity. Even though the concept of functional localization still has its critics, clearly we can no longer think of the brain as just one big tangled, plastic mess.

Psychologists have discovered many cognitive biases that actually reduce the accuracy with which we understand the world. For example, we are unduly influenced to value more those things that we already have. We can be “primed” to make a certain choice, judgment or perception just by prior passive exposure to emotion-laden stimuli. These and many other biases fit Fodor’s criteria that (a) a module is “mandatory”, i.e., operates automatically, and (b) is independent of other processes, in this case reasoning and even reference to previous experiences and beliefs.

In this time of high growth in the sciences of the mind, there are few things that most researchers would agree on. However, if you pick up any popular book about the mind, they nearly all will describe it in ways that mean: there are many interacting parts, most of which function without our needing to think about them, and often without us knowing about them. Given that, we have to ask, what can make such a thing the essence of a person? What holds all those parts together?

UNITY: Coherence of the manifold self (1)

Introduction

You asked, “How does the self learn to relate to the world?” But actually the self starts by dividing itself off from the world. Some parts, some sources, of stimulation are always here, others are not. That difference is one basis or beginning of selfhood. Then we elaborate it more, adding a social identity and relationships, and other things.
— Roy Baumeister,  Quid pro quo: the ecology of the self

Why in fact is there just one of you instead of a probability smear across a hive mind of some kind? The understanding of personal identity has been a puzzle for centuries. To grasp all that identity means now, we need to know what personal identity is at its core. Identity has continuity, cohesion and uniqueness, but each of these qualities can be somewhat hard to pin down.

All the evidence is that our minds consist of many interacting pieces, many of which are not even conscious. Nevertheless, the vast majority of us feel like, and present as, a single cohesive person, continuing over a lifetime. Much scientific and philosophical effort has been spent of late on the nature of the self and its conscious mind. It turns out that there is no single explanation for what holds you together. Instead, it is a coordinated meshing of multiple levels of reality: physical, personal, and social.

The physical level starts with DNA, but it’s really about how biological processes create encompassing boundaries within which are built the foundations of our uniqueness: a cellular structure, a nervous system and an immune system. We think that the physical body continues through our lifetime. In fact our component matter and structure changes continually, so that there is not really any specific physical thing we can claim to be us throughout life. Furthermore, quantum theory doesn’t even allow that any one of your atoms is the same from time to time. There essentially is no “same” to an atom. The prevailing theory, then, is that what persists physically is a pattern, not specific matter.

But there’s another level. Using our physical framework we develop a mental one. This is the reality interpreter called the Self. Thereby, we know things. The peculiar aspect of the human Self is that we self reflect. We know that we know. That Self intuitively believes in its own continuity over time but, like in the physical case, change is continual in the mind. This leads to interruptions and paradoxes that belie the continuity that we imagine ourselves to have.

What’s left to (finally!) hold us together? It’s our social environment. It’s our roles, our relationships, our tribes and institutions. We are the same person as last month because others who know us say that we are. We are the same person as an infant decades ago because our family knows it to be true. Our culture gives us an identity even before we are born, and it preserves it in some important ways even after death.

Throughout life these three levels of reality mesh to hold us together. The result is not only continuity, but uniqueness among our fellow humans. That uniqueness, as opposed to our place within family and society, is becoming more and more a focus of our conscious Selves. In the second decade of the 21st century, our “true self” has devolved into a personal brand, an attention-seeking marketing missile aimed at other people. It’s getting a little frenetic.
