Consciousness and the Social Brain

consciousnessAmazon: “What is consciousness and how can a brain, a mere collection of neurons, create it? In Consciousness and the Social Brain, Princeton neuroscientist Michael Graziano lays out an audacious new theory to account for the deepest mystery of them all. The human brain has evolved a complex circuitry that allows it to be socially intelligent. This social machinery has only just begun to be studied in detail. One function of this circuitry is to attribute awareness to others: to compute that person Y is aware of thing X. In Graziano’s theory, the machinery that attributes awareness to others also attributes it to oneself. Damage that machinery and you disrupt your own awareness. Graziano discusses the science, the evidence, the philosophy, and the surprising implications of this new theory.”

The (attention schema) theory explains why a brain attributes the property of consciousness to itself, and why we humans are so prone to attribute consciousness to the people and objects around us.

Consciousness is the window through which we understand.

Attention is a data-handling trick for deeply processing some information at the expense of most information. Awareness is the brain’s simplified, schematic model of the complicated, data-handling process of attention.

People have personal, quirky definitions of the term consciousness, whereas everyone more or less agrees on the meaning of the term awareness.

Not all information in the brain has awareness attached to it.

Consciousness refers both to the information about which I am aware and the process of being aware of it. Consciousness encompasses the whole of personal experience at any moment, whereas awareness applies only to one part, the act of experiencing.

Self-knowledge is merely another category of knowledge. How knowledge can be encoded in the brain is not fundamentally mysterious, but how we become aware of the information is. The awareness itself if the mystery.

Whatever awareness is, it musts be able to physically impact neuronal signals. Otherwise we would be unable to say that we have it.

Awareness is a description of attention. […] Attention is not data encoded in the brain; it is a data-handling method. It is an act. It is something the brain does, a procedure, an emergent process. […] In addition to doing attention, the brain also constructs a description of attention and awareness is that description. […] Awareness allows the brain to understand attention, its dynamics, and its consequences.

Awareness is the brain’s cartoon of attention.

The same machinery used to model another person’s attentional state in a social situation is also used to model one’s own attentional state. The benefit is the same: understanding and prediction one’s own behavior.

Attention is an active process, a data-handling style that boosts this or that chunk of information in the brain. In contrast, awareness is a description, a chunk of information, a reflection of the ongoing state of attention.

The unconscious machinery of the brain is so vast that it is like an elephant. Perhaps consciousness is a little boy sitting on the elephant’s head. The boy naively imagines that he is in control of the elephant, but he merely watches what the elephant chooses to do.

Your decision machinery does not have direct access to the real object, only to the information about the object that is encoded in the visual system. A perceptual representation is always inaccurate because it is a simplification.

The brain does attention but knows awareness.

(There is a ) distinction between being aware of something and knowing that you are aware of it.

Awareness is a schematized, descriptive model of attention. […] The purpose of (the) model in the brain is to be useful in interacting with the world, not to be accurate.

My awareness is located inside me. In a sense it is me. It is my mind apprehending something.

Your own private awareness and your ability to attribute awareness to someone else are products of the same machinery in your brain. That machinery computes the property of awareness and can attribute it to others.

Is it necessary to be aware of any specific information in order to be aware? Can you be aware, simply aware, without any target of the awareness? Can I be aware of being?

Consciousness (is) essentially a tale that the brain tells itself to explain what it is doing and why it is doing it. Consciousness is after-the-fact. We know about our mental states using the same tricks and inferences that we use to reconstruct the mental states of other people. We tell ourselves a story about ourselves. As a consequence, we routinely and confidently make up incorrect reasons for our own behavior.

Awareness is a model of the act of attention. […] Attention is not itself information. It is something that happens to information.

The only objective, physically measurable truth we have about consciousness is that we can, at least sometimes, report that we have it.

Consciousness is information that describes the process of attending to something.

Awareness is not knowledge about yourself as a person, or knowledge about your emotions, or knowledge about your thoughts; it is not remembering your past, or introspecting about your mood, or any other part of self-reflection. Awareness is equally present whether you are reflecting on yourself or looking out at the external world. It is present whether you are focused on your innermost feelings or on the grass and sky in the park on a nice day.

(One view of consciousness) Consciousness does not directly cause most of our actions but instead rationalizes them. In (this) view, free will plays a minor role, if any.

All consciousness is a “mere” computed model attributed to an object. One’s brain can attribute it to oneself or to something else. Consciousness is an attribution. (Consciousness) is not something a person has, floating inside. It is an attribution. […] To say that I myself am conscious is to stay, “My own brain has constructed an informational model of awareness and attributed it to my body.”

The most reasonable approach to spirituality is to accept two simultaneous truths. One, literally and objectively, there is no spirit world. Minds do not float independently of bodies and brains. Two, perceptually, there is a spirit world. We live in a perceptual world, a world simulated by the brain, in which consciousness inhabits many things around us, including sometimes empty space.

We will build computers that can construct their own awareness in the same way that the human brain does.

If I spend enough time (with him) and my friend gets to know me well, then he will construct a model in his own brain, an informational model of a mind filled with the quirks and idiosyncrasies that reflect me. His model of my mind will be the same general type of data run in the same general manner on the same general hardware architecture as my own conscious mind. It will be a copy, at low resolution, of my consciousness. In effect, I will have been copied over from one computer to another. […] Fuzzy copies of our conscious minds exist in all the people who knew us.

I consider it a technological inevitability that information will, some day, be scannable directly from the brain and transferrable directly to computers. As embarrassingly sci-fi as that sounds, no theoretical reason stands against it. If the attention schema theory is correct, then human consciousness is information processed in a specific manner. Don’t want to die? Download your consciousness onto a central server and live in a simulated world with all the other downloaded souls. When your body dies, the copy of your mind will persist. You need not know the difference. If the simulation is good, you should feel as though you are in a realistic universe. You can possess what seems to be a human body and can walk and live and eat and sleep on the familiar Earth, all simulated, all in the form of information manipulated on computer hardware. At the rate technology is advancing, give it a few centuries.

It has been said that people invented God. People will invent the afterlife too.

Across all cultures and all religions, universally, people consider God to be a conscious mind. God is aware. God consciously chooses to make things happen. […] The critical question is whether consciousness lies behind the events of the universe. If so, then God exists. If not, then God does not exist. […] The universe is conscious in the same sense that it is beautiful. It is conscious because brains attribute consciousness to it, and that is the only way that anything is ever conscious.

The ego is what you think you are

“The face in the mirror, and the haphazard story we associate with it, is the ego. (But) what we think of ourselves is constantly changing, not just day to day, but moment to moment, and mood to mood. At different times, I have thought of myself as anything from an insufferable loser, to a freaking genius, to a guy who can never quite get his shit together, to a guy who’s never had a serious problem in his life. What I think I am is so fickle and so dependent on moods and circumstances, that it can’t possibly be right — ever!”

This is what is people mean when they say the self is an illusion. It is a fictional character that is constantly changing. Therefor, not a real thing in the permanent, unchanging sense of the word real.

David Cain comes closer to explaining this than anyone I’ve read.

So I said to myself, “Self…”

If someone offered you a thousand dollars to write a 500 word essay titled “Who Am I?”… you could do that. You could knock out 500 words but I suspect most people have not given five minutes thought to this timeless, existential question.

A first draft would probably be heavily biographical. Your name; what you look like; where you’ve lived; what you do for living; maybe important relationships. You’d tell your story. So, are you your story?

The more introspective might try to describe some “essential self.” That “Real Me” that no one knows. “Thine own self” to which Polonius said we should be true. This is where you start listing all of the things you believe/know/think/fear.

Now, let’s say I give you a thousand bucks to write this essay every five years, starting at, oh, let’s say, fifteen. Now you’re 65 and we have your ten essays in front of us. Which one of those “you’s” is The Real You?

“All of them,” you explain. “That’s me at 25, that’s me at 40 (and so forth).” So, the essence, the core of who you are changes from year to year? How about month-to-month? Daily? Hourly? Sounds like there are many different Real You’s.

This is an ancient question that really smart people have thought about for thousands of years. My reading has lead me to the camp that finds no evidence of an essential, unchanging, permanent self.

I need a visual metaphor to even begin to *think* about stuff like this. Let’s try one.

Shortly after you’re born, you’re issued a little backpack. This is where you keep everything. The image of the giant people who take care of you; the smell of the places around you; the feeling you get when you’re hungry or you’ve pooped yourself. Since everything’s new at this point, your little backpack fills up pretty quickly but that’s okay because you get a bigger one whenever as needed.

All your experiences get stuffed into the backpack. If you need to know if you’re good or bad; smart or dumb; afraid or fearless… the answers are in the bag. It can get confusing because nothing ever comes _out_ of the bag but if it’s in there, it’s part of who you are.

By the time you reach your early teens you’ve traded in your backpack for a duffle bag and it’s packed! Including a couple of quarts of hormones that have soaked all those memories and feelings and beliefs. It is messy.

By the time you’re an adult, you’re dragging around a steamer trunk and adding more stuff every day. If the question, “Who am I?” comes up, well, you open the trunk and the stuff on top is you.

After dragging that fucker around for 60+ years, I’m ready to leave it behind. All the memories (good and bad) and fears and ideas and concepts and beliefs. Turns out, a lot of the stuff in that trunk was put there by someone else. Family, friends, strangers, you name it. After dragging it around for ten or fifteen years, it became “mine/me.”

The reason we don’t go insane thinking about this is we have something called the ego. But that’s just a character, like Willy Loman. A little different every time he walks onstage. Not real. For most of my life, I didn’t know it was a play. I thought I was Willy Loman. Now I’m sort of watching from the wings. I can see the make-up is a little different each performance, lines are delivered with slightly different inflection. I’m becoming aware it is a performance and that the lines aren’t mine.

“The self is impermanent. […] It is constantly changing, decaying, and being reconstructed again, always slightly differently, depending on the circumstances of the moment. […] It never repeats itself. Whenever you look, it is slightly different.” — Jon Kabat-Zinn, Wherever You Go There You Are

Why deconstruct the concept of the self (ego)? Apparently, that is the source of all suffering.

[This is where I ran out of gas on this post. Fortunately, I came across this post by Brian Hines who takes this idea on down the road.]

Consciousness

Conscious book cover“The idea that humans are special, that they are singled out by the gift of consciousness above all other creatures, stems from the deeply held Judeo-Christian belief that we occupy a privileged place in the order of things, a belief with a biblical but no empirical basis. We are not special. We are just one species among uncountable others.”

“Imagine a construction set of a thousand different types of LEGO bricks of distinct colors, shapes, and sizes. The human cerebral cortex has sixteen billion bricks chosen from these types, assembled according to fantastically elaborate rules, such as a red 2×4 brick is linked to a blue 2×4 but only if it is near a yellow 2×2 roof tile and a green 2×6 piece. From this is born the vast interconnectedness of the brain.”

“It is not the nature of the stuff that the brain is made out of that matters for mind, it is rather the organization of that stuff – the way the parts of the system are hooked up , their causal interactions.”

— Consciousness by Christof Koch

Excerpts from I Am That by Sri Nisargadatta Maharaj


All your problems are your body’s problems. All these lose their meaning the moment you realize that you may not be a mere body. You are nothing perceivable, or imaginable.#

Memory creates the illusion of continuity.

Time, space, causation are mental categories, arising and subsiding with the mind.

Nothing can happen unless the entire universe makes it happen. A thing is as it is, because the universe is as it is.

The world you can perceive is a very small world indeed. And it is entirely private. Take it to be a dream and be done with it.
