Consciousness and the Social Brain

Posted on by

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.

Meditation Now or Never

meditationPublisher’s Weekly: Zen priest Hagen, author of Buddhism Plain and Simple and Buddhism Is Not What You Think, offers a brief and wonderfully accessible primer on meditation, which can be a surprisingly difficult practice for many beginners. He helpfully defines meditation via negativa: meditation is not a self-help program, a quick fix, a mind-training technique or a way to relax before jumping right back into the fray of our busy lives. It’s a lifelong practice that can, and should, seep into every arena of the quotidian, so that when we’re attentively folding laundry or taking out the trash, we’re doing meditation. It involves teaching the mind just to be here, says Hagen. Amazon.

A few excerpts:

We live tuned in to ourselves, but tuned out from life.

We easily lose sight of the distinction between Reality and our ideas about Reality.

Meditation is an expression of faith in direct experience itself.

Meditation is useless. (Because) meditation is, finally, just to be here. Not over there, in some other place called peace or freedom or enlightenment. Not longing for something else. Not trying to be, or to acquire, something new or different. … We can’t do meditation for any reason other than to be aware. … If you’re sitting in meditation to get something — you’re not here.

Meditation is about deeply seeing what’s going on within your own mind.

In meditation, we see that there is no cosmic mystery to break through. … Reality and Truth don’t require any “figuring out.”

You can’t become enlightened (because) you’re already here, immersed in it. It’s like trying to become human.

The practice of meditation frees us from our insane desire to control ourselves and others.

If you can get past the resistance to meditation, nothing else in life will be an obstacle.

In each new moment we can live in either awareness or ignorance.

Our meditation practice reflects the attitude we take in life.

At the heart of meditation is the intention to be awake. (To experience) Reality as it is,before goals, ideas, or desires sprout. … Meditation is never a means to an end.

Meditation is not about doing anything. It is simply paying attention. … If our will is directed toward any object or purpose — even toward meditation correctly — then we’re not in meditation.

Meditation is continually returning to life so that we don’t miss it. There’s no gap, no distinction, between you and what you’re doing.

Instead of practicing now and here, we get lost in thought about it.

Enlightenment isn’t something we need to figure out. It’s just remembering — waking up to what you knew all along but were not paying attention to. There’s nothing to figure out. It’s only a matter of seeing and not talking to yourself.

Over time you’ll discover that meditation won’t give you ideas at all.

Meditation is a matter of zero or 100 percent. Either you’re present or you’re not. There are no in-betweens.

To the extent that we’re not fully present as we live our life, a good portion of our life passes away unlived.

Meditation is awareness.

The very distinction of “out there” and “in here” is just another mental construct. It isn’t Real.

The more present we are, the bigger the picture we see. The bigger picture we see, the more things seem to slow down. And when the Whole is seen, all is utterly still.

Almost everything we do is done for a purpose a result, an outcome. In meditation, however, we let go of hopes and fears, plans and outcomes, and simply come back to here and now.

The desire of one who is awake is simply to be awake.

We can ever really explain how we feel — we can only feel how we feel.

Waking up means, more than anything else, that we learn to see ourselves.

Meditation is about your attitude toward life.

We put together a world in our mind. We carry all kinds of ideas, beliefs, notions, and prejudices — and, for most of us, that is our reality. It’s where we live. We regularly confuse what we believe with what we actually know.

Everything in culture is built around the premise of going after something else.

We find awakening so elusive because we’re looking for it. And if we’re looking for it, that means we believe it’s not here.

There is no “out there.”

We need to awaken, again and again, in each new moment. And in each moment, we have a new opportunity to wake up.

Life is all at once. It’s forever now. It’s never “then.”

Rebirth

“You are lounging on a magnificent balcony open to the starry sky, divine music is playing with such exquisite perfection you can hardly stand it, when all of a sudden something terrible occurs: the magical sounds break up into an obscene cacophony. What is happening? Are you dying? You could put it that way. That awful noise is the first scream of an infant: you. You have been born into a human body hardwired with each and every transgression from the last time around, and now you must spend the next seventy years clawing your way back to the music. No wonder we cry.”

Who wants to die for a supermarket

“The greatest weakness of the West is that it has nothing with which to inspire loyalty except wealth. But what is wealth? Another washing machine, a bigger car, a nicer house to live in? Not much to feed the spirit in all that. What is the West but a gigantic supermarket? And who really wants to die for a supermarket?”

Immortality

Posted on by

book-coverThe Quest to Live Forever and How It Drives Civilization, by Stephen Cave (Amazon)

“The Mortality Paradox – On the one hand, our powerful intellects come inexorably to the conclusion that we, like all other living things around us, must one day die. Yet on the other, the one thing that these minds cannot imagine is that very state of nonexistence; it is literally inconceivable. Death therefore presents itself as both inevitable and impossible.”

“The Terror Management Theory – We must live in the knowledge that the worst thing that can possibly happen to us one day surely will. […] We have created institutions, philosophies and religions to protect us from this terror by denying or at least distracting us from the finality of death.”

“Immortality is not for the weak and foolish.”

“”Longevity Escape velocity” – living long enough to live forever”

“”Computational Resurrection” – the rerunning of software that is your mind on a new piece of hardware so that you might live again.”

“The Soul – the most influential single idea in the history of Western civilization”

“Whether or not we literally believe we have a soul that will go to heaven, the cosmic significance we ascribe to ourselves as unique individuals reassures us that we transcend mere biology. […] We are creating a myth of immunity to extinction.”

“Buddhists do believe in some essential part of you that survives the body in order to be reincarnated in accordance with the laws of karma. This is pure consciousness, stripped of all memories and convictions and the rest of the accumulated baggage of a lifetime. The Dali Lama describes it as a “continuum of awareness.””

“In Hinduism and Buddhism there is an undercurrent of recognition that the individual mind cannot continue without the body. Beyond the theory of reincarnation, which requires a soul robust enough to be punished for its past sins, there are hints of something more radical. Nirvana, for example, literally means “extinguishing” or “blowing out.” But what is it that is being “blown out” like a candle? Some Buddhists say worldly desires. Others, however, go further and believe it is the self that is extinguished. For some in the ascetic tradition, the source of worldly suffering is not just being in the world–it is being at all. Liberation therefore means to cease to be an individual altogether, or as the Hindus put it, to become one with the all, the Brahman.”

“We have already concluded you have no soul — no unchanging essence or immutable inner core. We could go further and say that there is, in fact, nothing that is the “real you.” You are just a collection of disparate thoughts, memories, sense impressions and the like, all bundled up together in a package we conveniently label a person. What is more, all these disparate parts are continually changing,as some things are forgotten and others learned, opinions changed and new memories formed. The question is, then, if you are such an ever-changing bundle, what does it mean for “you” to survive?”

“Psychologist Roy Baumeister has estimated the length of time for which most of us can expect to be remembered as seventy years. He points out that not many people can even *name* their great-grandparents.”

“People in modern cities long ago lost the ability to survive independently—we are utterly reliant on a complex higher level system for clean water, food, clothing, shelter, medicine, security and energy. Like the specialized cells of our bodies, which have given up their independence for the greater strength and security offered by life as part of a macro-organism, we have each given up our independence to be part of strong and secure superorganisms.”

“Individual humans are merely temporary forms taken by the single, shifting web of life on earth. If humans are not really separate things, then their births and deaths are also not real, but simply one way of seeing the rhythms of life.”

“The great social-reform movements of the last centuries — emancipation of slaves, equality between sexes and races, social welfare and son on — arose only when the preoccupation with the next world began to lose its grip on Western society. […] If this life here on earth is regarded merely as a series of tests for a place in another life, then it is necessarily devalued.”

“There are as I see it two sets of problems: on the one hand, the boredom and apathy that would result from having done and seen everything there is to do— that is, from having already lived a very long time—and on the other hand, the paralysis that would result from having an infinite future in which to do any further things. Both these problems, the backward looking and the forward-looking, threaten to suck the meaning out of life and leave one wishing for a terminal deadline.”

“Death is the source of all our deadlines.”

“Life as we know it may be too short to watch daytime TV, but eternity wouldn’t be.[…] Given infinity, time would lose its worth. And once time is worthless, it becomes impossible to make rational decisions about how to spend it. […] If civilization exists to aid our preparation into the future, then if that perpetuation were guaranteed, civilization would be redundant. […] Civilization exists to give us immortality, but if it ever succeeded it would fall apart.”

“We do not “see” or experience death; death is the end of all experience. […] Neither you nor I can ever literally *be* dead. Living things cannot be dead things. To talk of someone “being dead” is just a shorthand for saying they have ceased to exist. […] We can never be aware of (life) having an end — we can never know anything but life.”

“If you are happy now, then you are happy always, as there is only now.”
