Incognito – The Secret Lives of the Brain

It’s easy to think of “me” has “having” a brain, but this book left me thinking my brain has me. If there is a me apart from my brain, I fear it’s mostly along for the ride. Here are some ideas that brought out my highlighter.

The brain generally does not need to know most things; it merely knows how to go out andretrieve the data. It computes on a need-to-know basis. pg 28

You’re not perceiving what’s out there. You’re perceiving whatever your brain tells you. pg 33

We have no access to the rapid and automatic machinery that gathers and estimates the statistics of the world. pg 34

Your brain is in the dark but your mind constructs light. pg 40

The difference between being awake and being asleep is merely that the data coming in from the eyes anchors the perception. Asleep vision (dreaming) is perception that is not tied down to anything in the real world; waking perception is something like dreaming with a little more commitment to what’s in front of you. pg 45

It’s easy to spot a hallucination only when it’s bizarre. For all we know, we hallucinate all the time. pg 46

Our expectations influence what we see. There has to be a match between your expectations and the incoming data for you to “see” anything. Awareness of your surroundings occurs only when sensory inputs violate expectations. pg 48, 50

The brain refines its model of the world by paying attention to its mistakes. pg 49

The brain tries to see the world only as well as it needs to. We are not conscious of most things until we ask ourselves questions about them. What we perceive in the outside world is generated by parts of the brain to which we do not have access. pg 54

Instead of reality being passively recorded by the brain, it is actively constructed by it. pg 82

There are thoughts you cannot think. pg 82

Evolution has carefully carved your eyes, internal organs,sexual organs, and so on — and also the character of your thoughts and beliefs. pg 82

“In general, we’re least aware of what our minds do best.” — Marvin Minsky, The Society of Mind

We are not able to see the instincts that are the very engines of our behavior. These programs are inaccessible to us not because they are unimportant, but because they’re critical. Conscious meddling would do nothing to improve them. pg88

Briefly glimpsed people are more beautiful. pg 92

We come to know our own attitudes and emotions, at least partially, by inferring them from observations of our own behavior. pg 134

The Great Mystery

“I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.” — Stephen Hawking

“We’ll be alive again in a thousand blades of grass, and a million leaves, we’ll be falling in the raindrops and blowing in the fresh breeze, we’ll be glittering in the dew under the stars and moon out there in the physical world which is our true home and always was.” — His Dark Materials by Phillip Pullman

“You’re a collection of molecules and those molecules are made of smaller bits, and those bits are made of even smaller bits. The smallest bits in the universe are all identical. You are made of the same stuff as the concrete in the floor and the fly on the window. Your basic matter cannot be created or destroyed. All that will survive of what you call you life is the sum of your actions. Some might call the unending ripple effect of those actions a soul, or a spirit.” – The Religion War by Scott Adams

“When you die, it is said you see your whole life. But you don’t see it minute by minute, like a speeded-up film. It’s like everything you ever did in all your days was a brushstroke, and now you see the whole painting all at once.” — Lawrence Block’s Everybody Dies

I wonder how it all got started, this business about seeing your life flash before your eyes while you drown, as if panic, or the act of submergence, could startle time into such compression, crushing decades in the vice of your desperate, final seconds.
From The Art of Drowning by Billy Collins

You’re going to stay here for a week. Everyone gets a private room. Please feel at home. But while you’re here there’s one thing you must do. Out of the __ years of your life, we’d like to ask you to choose one memory, the one you remember and cherish most. There is a time limit. You have three days to decide. After you choose your memory, our staff will recreate it on film as exactly as possible. On Saturday we’ll show the films to everyone. The moment the memory comes back to you most vividly, you’ll go on to the other side, taking only that memory. — From the motion picture After Life

“Imagine that existence is like a sound recording. Listening to an old phonograph doesn’t alter the recording itself, and depending on where the needle is placed, you hear a certain piece of music. This is what we call the present. The music, before and after the song now being heard, is what we call the past and the future. Imagine, in like manner, every moment and day enduring in nature always. The record does not go away. All nows (all the songs on the record) exist simultaneously, although we can only experience the world (or the record) piece by piece. We do not experience time in which “Stardust” often plays, because we experience time linearly.” — Biocentrism by Robert Lanza (with Bob Berman)

“In spiritual terms the cycle of birth and rebirth is a workshop for making creative leaps of the soul. The natural and the supernatural are not doing different things but are involved in transformation on separate levels. At the moment of death the ingredients of your old body and old identity disappear. Your DNA and everything it created devolve back to their simple component parts. Your memories dissolve back into raw information. None of this raw material is simply recombined to produced a slightly altered person. To produce a new body capable of making new memories, the person who emerges must be new. You do not acquire a new soul, because the soul doesn’t have content. It’s not “you” but the center around which “you” coalesces, time after time. It’s your zero point.” — Deepak Chopra, Life After Death

Living As A River

living-riverLiving As A River: Finding Fearlessness in the Face of Change, by Bodhipaksa

The ultimate act of letting go is to abandon the delusion that consciousness and the world are separate things.

Because we fear our own eventual extinction, we construct the idea of a permanent self.

(The Buddha) saw the self as composed of a number of ever-changing processes.

Knowing that I exist, it’s hard for me to imagine never having existed, and so in my own mind there’s a certain inevitability about my existence.

When we try to imagine death, what comes to mind is imagining an experience of nothingness, as if we’d still be around to have a non-experience. […] We simply cannot imagine not being able to experience anything at all, because experience is all we know, and so we’re forced to imagine experiencing non-experience.

Since we assume that the self existed before conception and will exist after death, we’ll inevitably imagine that it persists — unchanged — throughout life.

Once we start naming things, our language reinforces our underlying tendency to see them as fixed. We name things, and then we assume that because the name is static, so too is the thing named. The mind takes the language it uses to label reality as if it were reality.

It is (the) flow of events that constitutes what we call consciousness. Consciousness is not seen as being something separate that “has” experiences. Consciousness is the activity of experiencing.

The sage at peace recognizes that aging and dying are simply stories we weave for ourselves.

The opposite of suffering turns out not to be simple happiness, but something indefinable.

We may try to shelter ourselves from an awareness of impermanence by identifying with a nation or religion or with an abstract principle such as progress. […] To cling is to seek a stable refuge in the midst of a torrent of impermanence. […] The more our sense of well-being is dependent upon something impermanent, the more there is an undercurrent of fear. […] Fear leads to clinging, which leads to fear.

Insight is not the same as intellectual understanding but is a direct recognition of impermanence in our experience.

Everything that constitutes us is in fact a process, rather than a thing or object.

“Verbal thinking” – a scrolling tickertape of more-or-less connected words that streams endlessly through the mind.

(The body is) a process that has continuity rather than identity. […] There is no being, only becoming. There is no identity, only change.

In sensing my body as a river, I begin to realize that I do not know what I am. I begin to realize that there is nothing — “no thing” — to cling to or to identify with. One cannot hold onto a river.

If the earth were shrunk to the size of a soccer ball, the average depth of the ocean covering it would be sixty-five microns, or about twice the thickness of a grocery-store plastic bag.

Life is the sustainable self-organization of energy within the material world. […] Life itself is flow, and the energy of life cannot be grasped or possessed.

We need to hold definitions lightly, remembering that they are the map rather than the territory.

Despite Copernicus, we tend to think that we are at the center of the universe — that it all exists in order to serve us. But rather, we are scavengers of energy, peripheral to the vast processes unfolding around us.

Clouds make a good analogy for the illusory nature of the self. There’s nothing permanent in a cloud, just as there’s nothing permanent to be found in the self. The cloud is not separate from its environment, just as my self has no separateness. Just as the cloud lacks the essential qualities I assume a “thing” has, so too does my self lack the qualities I assume a self has. In looking at mists or a cloud; we can see a form, often with an apparently well-defined edge, and yet there’s nothing there that can be grasped. The fact that we name something a “cloud” often seems to create in the mind the assumption that the thing that’s being named is as static as the label applied to it. Often we’ll glance at a particular cloud and then look at it a short while later. Nothing much seems to have changed, because the human mind is not well-equipped to perceive change—especially not in something as amorphous as a cloud.

All concepts are simply labels superimposed upon the reality we perceive.

As we move toward the idea of abandoning the idea of a separate selfhood, we may need to go through a phase of treating the whole of creation as if it were us. […] Extend the idea of the self out far enough, and the idea of the self becomes meaningless.

As I sit breathing in my meditation practice, I might find myself wondering exactly at what point a particular molecule of air could be said to be “in” the body. Is it when it crosses some arbitrarily drawn plane enclosed by the rims of my nostrils? Is it once it’s crossed into the bloodstream? Or bonded to a molecule of hemoglobin? Any line I choose to draw would be purely arbitrary. I look for the boundary of my physical self and can’t find one.

Noticing how my gaze can often fixate on a narrow area in front of me, I become aware of the entirety of my visual field, allowing into awareness everything from the center of my visual field to the periphery. It’s like moving from a kind of “dial-up” connection between the world and my brain to a “broadband” one. Doing this generally has a very calming effect on my inner chatter, as if the sheer volume of incoming data I’m paying attention to leaves no bandwidth available for my inner dramas.

All experience takes place in the mind. […] We can know nothing beyond our sensory experience.

Consciousness is the activity of being aware of something. There can, by definition, be no consciousness separate from the things of which it is aware. […] We can never know objective things separate from our sense-impressions, which are interpretations rather than reality.

There can be no consciousness without something to be conscious of.

There is nothing stable within the mind. There is no permanent core. Perceptions, feelings, thoughts, and emotions are simply flowing through us, but are not us. Consciousness is an activity. It’s there when it happens.

Our identity depends on the internalization of the consciousness of others. Consciousness, like all the other elements, is therefore something that extends beyond the individual and that, in some sense, flows through us like a river.

Each event of cognizing is “a consciousness.” Since perceptions come and go, so too will consciousness come and go. Each response to a perception is another consciousness. There is no enduring consciousness, no permanent watcher at the helm of our being, observing everything that happens and making decisions. There are just the multiple overlapping waves of consciousness, rising and falling, rising and falling.

Our decision-making is a post-hoc conscious labeling of activities that begin outside of awareness.

Where is the self when conscious awareness is absent?

Memories are not etched permanently in the brain. Instead, every time a memory is retrieved, it is destroyed and then re-created, and it becomes a memory of a memory. Any current memories we have are copies of copies of copies… many times over depending on how many times we have recalled that particular experience. Because of this process of creating, destroying, and re-creating memories, our recollections are unstable and subject to alteration. Each time we recall an event from our lives, the memory of that event can change. […] We never have a full recollection of anything that’s happened to us, and our memories are constructed from hints, scraps and traces found within the mind.

“We are never conscious of anything but a particular perception; man is a bundle or collection of different perceptions that succeed one another with an inconceivable rapidity and are in perpetual flux and movement.” — David Hume

The underlying principle of selfhood in Buddhism: there is continuity but no identity.

I am a field of awareness in which all my experiences arise.

It’s largely our thoughts, and the emotional qualities associated with them that create our experience. […] In every moment of perception, we are able to choose between (fear and love). Fear is marked by clinging, aggression, doubt, anxiety, and denial. Love is marked by letting go, being flexible, compassionate regard, confidence, and intelligent curiosity. We have these choices in every moment of our lives.

Every time we make a choice, we play a part in forming a new version of the self, and we also remind ourselves of the self’s unfixed nature. We begin to see more and more clearly that our present experience is produced by largely unconscious patterns of thought.

There is no succession of fleetingly short selves, but instead a never-ending process of change. (No self!)

We simply let go of identifying any part of our experience as the self. Since we don’t cling to anything as being the self, we also don’t think of anything as being other than the self. […] There is simply experience, with no absolute distinction between subject and object. There is no idea “I am perceiving.” there’s no idea that there’s a separate world being perceived. There’s just experience.

Memory is fiction

A recurring theme in some of my recent reading has been the nature of subjective time. Among other insights, that the past and the future are delusions, created by the mind. This is a little easier to grasp for the future. Any ideas we have about what is going to happen is clearly fiction. But the past feels more “real.” It happened. I remember it. But that’s fiction as well.

“A memory is only as real as the last time you remembered it. The more you remember something, the less accurate the memory becomes. The larger moral of the experiment is that memory is a ceaseless process, not a repository of inert information. It shows us that every time we remember anything, the neuronal structure of the memory is delicately transformed, or reconsolidated.” — The Frontal Cortex

This reminds me of the scene in Blade Runner when Rachel discovers her memories are implanted. A disturbing thought because (for most of us) we ARE our memories.

But if that’s not really so, if our memories are fiction, who are we? Probably not who we think.

Daniel Kahneman: Riddle of experience vs. memory

This talk runs 20 min and I realize most of you won’t invest that much time. And I’m not sure I can summarize, but let me try: There are the experiences in our lives… and our memories of those experiences. And they are not the same. Our “happiness” ( a word that no longer has much useful meaning) has more to do with the latter.

As for the future?  Kahneman  says “we think of our future as anticipated memories.”

My understanding (based on my reading on this topic): The past and the future are delusions, stories. Created by the mind to protect the ego. Only now -this moment- has any reality.

Time travel companion wanted

The following listing recently appeared on the Springfield, MO Craigslist:

“I have a functioning time machine (i know it sounds unbelievable, but I assure you it works) that I need a 2nd person to operate with me. I’m looking for someone who is adventurous and reliable. Preferable a male; or a female that can do heavy lifting. I am leaving on January 20, 2011 , in the morning and plan to return February 3,2011. I am going to June 1983 to handle some business.

If you are serious about time travel and are reliable, then please contact me. You do not have to pay anything, but you would have to provide someone to watch my cat for the time we are gone. The only qualifications needed are that you are reliable and that the circumference of your head is no more than 64cm.

We will be leaving from Springfield,Mo. Let me know if you want to go with me.”

My friend David Brazeal responded:

I stumbled upon your advertisement on Craigslist on the afternoon of January 20, 2011 — too late to join you on your excursion into the past.

Fortunately, having dabbled in time manipulation myself in the late 1830s, I was able to travel to January 17th, one day after you posted your listing, from which time I am responding.

I am both reliable and adventurous, and well-acquainted with 1983, having spent that summer as an intern in the State Department’s Office of Botswanan Affairs. In addition, I have an elderly aunt who loves cats.

Regarding your qualification that my head be less than 64cm in diameter, I assure you that, although my head is slightly too large for a standard time travel headpiece, I have crafted an adapter from a 1960s Oster beauty-salon hair dryer and the innards of a PlayStation 3 controller.

Please let me know as soon as possible whether you still require a companion for your trip. If you have filled the position, I need to return to January 20 to take some brownies out of the oven.

One more thing…

David is leaving our company (after 17 years) in a month or so, to strike out on his own (uh, should I rephrase that? Fuck it). The post above is just one more example of what I mean when I describe someone as “too funny for their job.”

TED Talk: Time and gravity

Prof. dr. Wubbo J. Ockels is a Dutch physicist, and also the Netherlands’ original astronaut. He is a Professor of Aerospace Sustainable Engineering and Technology at the University of Delft.

TEDxAmsterdam: Wubbo Ockels from TEDxAmsterdam on Vimeo.

Ockels explains how ‘time’ is created by human beings, as a way our brains can make sense of gravity. The speed of light is constant, because it is made by us: it’s the clock by which we have calibrated our existence.

Don’t interfere with the flow

“There is a profound Buddhist doctrine that speaks of a great river that flows through all of reality. Once you have found yourself, there is no more cause for action. The river picks you up and carries you along forever after. In other words, effort from the personal level, the kind of effort all of us are used to in daily life, becomes pointless after a certain point. This includes mental effort. Once you become self-aware, you realize that the flow of life needs no analysis or control, because it’s all you. The great river only seems to pick you up. Actually, you have picked yourself up — not as an isolated person, but as a phenomenon of the cosmos. No one gave you the job of steering the river. You can enjoy the ride and observe the scenery.”

I like that. I found it in a book by Deepak Chopra (“Reinventing the Body, Resurrecting the Soul”). I’m not recommending the book (you’ll read it if you’re supposed to). But this is where I jot done some of the lines and passages that I want to remember or find again.

“Eternity is a very long time, especially towards the end.”

One of our networks received an email from a listener/reader this week, objecting to our use of the adjective "elderly" to describe a 56 year old woman who was killed in a tornado. I'm sure I once considered 56 "elderly" (ancient?) but no longer.

The next day I received a phone call from an old friend of my father, Luther Pillow. He's 86 and still works ("when I want to"). Sounded very healthy and sharp. Assured me he'd get back online and check out my KBOA website.

In a little more than two weeks, I will have been working for our company for 25 years. Have you figured out the math yet?

Mr. Pillow is 25 years older than I. Which means –health and circumstances permitting– I might be nearing the halfway point in my current employment.

Think of it. 50 years with one company. And what changes will I see in the next quarter century?

No, I don't think 56 is elderly.
