Nicholas Humphrey on why subjective experience feels “like” anything

Nicholas Humphrey at London Book Fair 2012

 

During my visit to the London Book Fair, I interviewed Nicholas Humphrey for the BookBaby eBook release of the 20th anniversary edition of his great work A History of the Mind.

In this clip, I ask him about what philosophers mean when they say that it feels “like” something to have subjective experience, and why he makes a distinction between perception and sensation.

Nick believes that perceptual knowledge, by itself, lacks qualitative information.  I perceive that the door is closed, but it doesn’t feel “like” something that it’s close; I may know that Paris is the capital of France, but knowing that doesn’t feel “like” anything in the way that eating a peach or hearing a siren does.  That’s because there’s a sharp distinction between perceptual knowledge and sensory expression.

Humphrey argues that we perceive in parallel with sensation, rather than building perception up from nested levels of sense data.  His experiments in blindsight show that higher level perception can go on without sensation – for blindsight sufferers, they can, in a sense, see, but it’s not “like” anything for them and doesn’t enrich their lives.  Nick’s take is that we have an ancestral pathway which supplies us the rich sense of being touched by light, smells, etc., and the experience of what’s happening to me at the moment, the thick moment in which stimuli are touching me and I’m responding to them.  This activity generates a reverberating loop which extends the moment of consciousness beyond the physical instant so that we feel that we’re living in “thick time,” the “thick moment of consciousness.”

I asked Nick why, it feels “like” something when I’m working on a difficult math problem.  He replied that while we’re working out of problem, we’re working not just with our brains, but with our bodies too: often we’re clenching fists, hunched over, and generating somatic sensations that are part of sense of working on the problem – they’re genuine sensations with qualitative dimension supplied by feedback from bodies.  So it’s not the cogitation producing that feeling – it’s the way our bodies are involved in almost everything we do.  For Humphrey, it may be “like” something  to solve a math problem, but not “like” something in the same way as it is when, for example, seeing red.

The idea of it feeling “like” something to have subjective experience was introduced by the philosopher Thomas Nagel to get at the qualitative dimension of sensory consciousness.  Nick believes that seeing red is “like” something because it has a time dimension it couldn’t have – it seems to outlast the physical moment, flowing on in subjective time from thick moment to thick moment, each one seeming to outlast its physical presence.  But while sensation is flowing on it’s not happening in physical time but instead in subjective time, from thick moment to thick moment which seems to outlast its own presence.  While that’s a physical impossibility, we feel it’s “like” that – it *couldn’t* be that, but seems to be “like” that.

On the difference between spirituality and religion

Nicholas Humphrey at London Book Fair 2012
During my visit to the London Book Fair, I interviewed Nicholas Humphrey for the BookBaby eBook release of the 20th anniversary edition of his great work A History of the Mind.

In this clip, he discusses how religion is parasitic on the human impulse to spirituality. Humphrey considers “spirituality” to stem from the “mind-body problem” which still dogs science and philosophy: how can our qualitative experiences be produced solely from the material substance of the brain? The fact that our sensory functions provide us with such rich experiences give rise to the notion that we have a “soul” as the seat of experience.

Every day, we awake to amazing sensations, a new universe we create within ourselves which is essentially unshareable – and the idea that we’re focal singularities of consciousness gives rise to the feeling of “spirituality” – that we’re special because we’re hosts to internally generated, out-of-the-world phenomena.

Humans are therefore profoundly individualist, and they discover the importance of selves through private experiences which they can glory in, develop, and feed, as a bubble of consciousness which no one else can enter. And when we attribute similar experiences to others, it changes our relationship to the world in ways which are hugely productive. So the notion that we have “souls” has transformed society – leading us to empathize with others whom (we assume) also feel as the centers of their own private experience.

For Humphrey, those impulses have been subjugated and captured by religious systems , which are parasitic on human spirituality. The real problem of having a “soul” which matters so much to us is that we invest so much in it. Our experience is that this “soul” disappears every night, but we’ve always had it come back. A primary driver of human achievement is the illusion – and mistake – that it will go on forever.

On the difference between perception and sensation

Nicholas Humphrey at London Book Fair 2012
During my visit to the London Book Fair, I interviewed Nicholas Humphrey for the BookBaby eBook release of the 20th anniversary edition of his great work A History of the Mind.

In this clip, he discusses the phenomenon of blindsight as evidence of there being different internal pathways of sensation and perception. For Nick, perception is time-independent judgment of what’s “out there” in the world, and sensation is sensation involves the subject’s own interaction with stimuli, an active process which is an emotion-laden and which accrues through time.

An experiment showed him the reality of the distinction. The visual cortex in the back of a monkey’s brain was removed, but while the monkey believed she couldn’t see, she managed quite well visually, picking up objects and navigating through the world, although she had to be continually persuaded to do it. Some humans with damage to their visual cortex have “blindsight” as well – they will say they’re blind and feel no visual sensations, but if you ask them questions, they have access to a fair amount of visual information.

Humphrey’s conclusion is that information alone is not enough to create the feeling, the joy, the sense of presence and involvement in the act of “seeing.” These blindsight patients are lacking the dimension of sensation and cannot react internally to the stimuli’s qualities with emotional bodily expression. And that expression – that active response – is the basis for the “qualia of sensation,” the qualities we value so much when talking about consciousness.

Nicholas Humphrey releases 20th Anniv. edition of A History of the Mind through BookBaby

It’s a joy to be releasing the 20th anniversary edition of Nicholas Humphrey’s A History of the Mind through BookBaby.  I had the great pleasure of writing the forward for the book and interviewing him at the London Book Fair this year.

Nick says that the book was the result of years of research and theorizing of what it’s like to be conscious, to live in what he calls “the present tense of sensation.”  AHOTM was written to be complementary to Daniel Dennett’s seminal work Consciousness Explained.  Whereas Daniel Dennett’s book discusses the mind as decision-maker, an apparatus for creating future, and a “cerebral office,” Nick emphasized the human self, and how it takes delight in the feeling of being alive.  Humphrey’s take is that we are active participants in sensation: rather than there being anything in the world inherently red, salty, or painful, our experiences are created by us and projected out into the world.  In this way, we are participants in our own experience and light the world up with our own consciousness.

Here’s his video introduction to the book:

Father to a 7-year-old existentialist

Albert Camus, Nobel prize winner, half-length ...
Image via Wikipedia

Last night, we were eating dinner at a stargazing gathering in the Mojave desert. Anatol made a comment about death, and I commented, “That’s my little existentialist.”

Anatol: “What’s an existentialist?”

Me: “Existentialism is a school of philosophy which was big after World War II… you know, Camus, Sartre… OK, it means that even if life seems absurd, you have to create your own meaning…”

Anatol: “I don’t understand.”

Me: “Suppose I were to ask, what’s the pupose of life and why are we here?”

Anatol: “We’re here because of the explosion of a supernova!”

At this, the scientists at the table from NASA and JPL pricked up their ears.

Me: “No, I mean… let me put it this way: A lot of people believe in God, and that’s OK, but suppose you don’t – what do you think, then, is the meaning of life?”

Anatol: “The meaning of life is 42!”

The whole table laughed.

Anatol: “Daddy, can I go roast some marshmallows now?”

My 7-year-old is quite proficient in finding his own meaning and living sincerely and passionately, and I’m here to help him roast those marshmallows.

Book review: Nicholas Humphrey’s “Soul Dust”

In an earlier post, I wrote about how the dinner I had at Nicholas Humphrey‘s house while visiting the UK for the London Book Fair. I was so moved that I decided to post here a book review I wrote for his latest masterwork, Soul Dust. Enjoy!

Why do people have qualitative phenomenal experiences, and why is it “like something” to have sensations? And why do we feel special and spiritual, as if we existed in a “soul niche?” In his marvelous book Soul Dust, Nicholas Humphrey provides perhaps the most sensible solutions to these fundamental but seemingly-intractable questions, and he offers some credible possibilities how and why consciousness likely evolved with these features.

The first half of Soul Dust is a whirlwind tour through Humphrey’s thoughts on sensation and why first-person experience feels like it does. As the author favors brevity, this part of the book is dense and requires some mental lifting on the part of the reader. Humphrey explains how natural selection could “adjust the properties of existing sensory feedback loops so as to steer the activity toward a special class of attractor states… [which] would seem, from the subject’s point of view, to give sensations their phenomenal properties.” Then, he illustrates multiple lines of evidence on what consciousness is for – why it may not enable you to do something but still has the crucial function of encouraging you to do something – and that primary individualism, by helping us develop a theory of mind, is beneficial for the individual *and* for the social group. Finally, he surveys the important work of scientists and convincingly argues why philosophers are still necessary, arguing that “the probability is that brain scientists would not recognize the NCC [neural correlates of consciousness] for what it is even if it were right in front of them.”

With this foundation in place, it’s the second half of Soul Dust which truly astonishes, for here, Humphrey shows why life can be beautiful in the face of death. Drawing on multiple lines of evidence (from for types and degrees of consciousness and “presentism” in other animals; poetry; primitive art, psychological studies; and even the last meals of death row inmates), Humphrey describes how and why we take pleasure in existence in itself. If natural selection can arrange pleasure in the feeling of existing, existing can become a goal, and you can plan and go through pain or delayed gratifications to achieve or continue it. In a brilliant move, Humphrey shows how and why our experience and the structure of our minds guide the false intuitions that our “souls” could somehow live on after bodily death. This helps explain why reductionist theory is counterintuitive for so many people and how religion rides as a parasite on our natural predilection for spirituality (and not vice versa).

The beautiful final chapters provide strong evidence for how phenomenal consciousness is a “magic show” you stage in your head which lights up the world so you can feel special and transcendent, and why it’s adaptive for you to feel that way (as well as even to have death anxiety). In so doing, Humphrey gives voice to the notion that there is actually beauty in being a creature which knows it’s going to die.

For thousands of years, people have told crazy stories to explain and to comfort each other in the face of death, tales which include positing earth-centered creation, the permanence of souls, and even consciousness as a separate fundamental element of the universe. But, to quote the film True Grit, “I do not entertain such hypotheticals, for the world as it is is vexing enough.” It can seem like a dark joke to have a subjective experience of consciousness for such a brief period of individual existence. But this book finds meaning and beauty in our brief skein not as a fairy tale a “gallows-humor” consolation prize; it shows how this “magical mystery show” of consciousness and sensation over a limited timeframe is actually lovely, and in so doing, it gives the reader the feeling that everything is illuminated. “Sentio ergo sum” (“I feel, therefore I am”) indeed!

Soul Dust is worth every minute of attention it demands, and it’s a mind-expanding, life-affirming work.
