Will science ever solve the hard problem? An object in this You (whoever reads this) has an inner life Antonio Damasio’s TED talk is excellent. On the inner life being an illusion, I don’t know that we actually do need it to be. Why Do You Remember The Past But Not The Future? CDZs exist in hierarchies. Change ), You are commenting using your Facebook account. It is heavily dependent on memories, along with the projections it makes for the future. Homeostasis and balanced equilibrium. as Damasio dubs it, is the Protoself. Of course, it may well be possible to use an alternate data processing model to produce the same behavior, which could imply a behavioral zombie. I haven't read Damasio's book and don't really know enough of this theory to create this article. In Damasio’s view, consciousness centers on the self. So, I agree that HLC is implemented via the brain stem while the intelligence is produced in the frontal lobe (see http://www.prequark.org/inte001.htm ). Then I realized that he was addressing primal first person experience, the state of a self experiencing perceptions and what those perceptions immediately mean to the self, to the body. From these associations, we are able to later recreate a version of the original image, although it’s never as detailed as the original since the recreated version doesn’t have the sensory data stream coming in. From this realization, springs Damasio's Things like shock don’t simply rectify themselves when a stressor is removed. Our internal self model of our mind is simplistic, mainly because there was no evolutionary need for it to be more accurate. . ... 2 CORE CONSCIOUSNESS AND CORE SELF Life systems that have been evolved beyond the level of … 1 Introduction In (Damasio, 1999) the neurologist Antonio Damasio puts forward his theory of consciousness. A relationship is I wasn’t sure of usage rights so I didn’t reproduce them here, but here are some diagrams showing the CDZ hierarchies in action. changes it is experiencing as a result of external or internal stimuli. Brains are systems evolved to preserve homeostasis and ensure survival. And at its root homeostasis gives us stromatolites, not consciousness. And the most primal level of this resonance starts in the brainstem. Consciousness and how it relates to the body and emotions is one of my favorite topics of inquiry. The same neurological stories mentioned in the review are in ‘Self…’. The lowest hierarchies receive inputs from image areas and can both output back to the those image areas as well as upstream to next level of CDZs. ( Log Out /  The proto-self’s formation begins in the brainstem, although in healthy humans the insular cortex, an area in the fold between the parietal and temporal lobe, is also involved. This occurs when the patterns contributing to I’ve never seriously considered the possibility that other people are zombies, but I just don’t see any way to explain my own experiential reality in purely physical terms. a donut), which is just a theory about the software and hardware of the brain. It doesn’t make a difference then, if you think of physiology acting like the thermostat in your house, i.e. For example, the vividness of red may be due to the fact that most primates eat fruit and ripe fruit on the African savanna is often red. But he says it is pretty much impossible to introduce better words to a wide audience so he reluctantly lives with a commonly used but ultimately limited one. This leads to a discrepancy between that simplistic model and objective data about the brain. These are the areas that drive memory, imagination, emotions, and actions. Excellent overview and thanks for the reminder – his ‘The Feeling of What Happens’ is still on my list – speaking of which, and with hindsight – I think I wish I’d read prior to ‘Self Comes …’, https://www.nytimes.com/books/99/10/24/reviews/991024.24calvint.html. Central to Damasio’s theory of consciousness is the idea of biological value, that which helps in preserving homeostasis, which of course aids in survival. The image of the bear that probably popped in your mind while reading the previous sentence was, according to Damasio, recreated from the bear related CDZs in your brain being triggered by the word “bear.”. Thank you for a very informative review. One possible flaw I see in this overall framework is that it’s more a theory of self than of consciousness in particular. To begin with, Damasio describes two types of brain areas: image making areas, and dispositional areas. Wouldn’t you say it is true that every aspect of life is rooted in physics and chemistry that life bootstrapped upon? emotion manifest as mental images, or brain movies. They have the same goals, but allostasis recognizes there’s more in the system than reactions. Three important concepts in this theory are ‘emotion’, ‘feeling’ and ‘feeling a feeling’ (or core consciousness). That being said, I think it helps to ask, from an evolutionary perspective, why do we have an inner life? Thanks for your thoughts. state of the physical structure of the organism" (Damasio 1999). These awareness signified by a collection of neural patterns We assume other humans have an experience similar to ours because we all seem like similar systems, but the further we move beyond that (other primate species, mammals, vertebrates, machines, etc) the more doubt about how similar their experience is to ours. Likewise, biological systems don’t necessarily struggle to get back to a set point until they fail. I don’t think Damasio is asserting that only systems with brains (or even only living systems) have homeostasis, only that the need to maintain it is shared by all living organisms, and that brains are one evolutionary solution for preserving it. Is very puzzling but grander philosophical structures have been built on flimsier foundations. Damasio makes no pretense of his theories being the final word, only that they add possible explanations of what is happening, and I think they definitely do that. A non conscious state, this Obviously, {intelligence and consciousness} are closely related but definitely different. Yes, it all starts there, but for human like consciousness, even the proto-self requires the insular cortex, core consciousness requires the thalamus and early sensory cortical areas, and autobiographical consciousness, the full human level experience, requires large portions of the neocortex. They also generate actions. In that sense, the hard problem of consciousness may become like the hard problem of light in the 17th century. Change ), You are commenting using your Twitter account. ( Log Out /  finally, Extended Consciousness. Thanks for the explanation. When I first read Damasio’s description of this core self concept, I wondered what he was talking about? Relating consciousness to fundamental physics seems similar to Penrose’s approach, although Penrose is looking for a new physics. No one could understand how the color white came into existence, how it became “clean” and pure. Of course, in reality the language of technological computation is (currently) transistor states, but we build layers of abstraction (languages) between the raw machine and us to make it easier to work with. My favorite philosopher of mind is David Chalmers, who makes a distinction between the hard problem and the easy problem of consciousness: the easy problem being “how does the mind work”, and the hard problem being “why is a mind conscious”. Further from the sensory pathway areas are the dispositional portions. CDRegions are probably created from genetic information, as are many primordial CDZs, but most CDZs get created from experience, from learning. Still, there’s a lot here that strikes me as very plausible. No, I think you’re right that we can never know beyond any shadow of doubt that anyone else is conscious, that everyone beside ourselves aren’t philosophical zombies. It uses these signals to construct an image map of the body. Emotions are a collection of unconscious neural responses to qualia. That said, I’d imagine you can find ‘The Feeling…’ online somewhere; Amazon shows used hardcovers from 1 cent up. Developed in his (1999) book, The Feeling of What Happens, Antonio Damasio's three layered theory of consciousness is based on a hierarchy of stages, with each stage building upon the last. This site uses Akismet to reduce spam. I like the stress on the importance of feeling within this theory of consciousness. So, their implementations can be different via different machines. That action can be to trigger the release of hormones, to initiate muscle action, or maybe to inhibit action arising from another cluster of CDZs. Now, will the people troubled by the hard problem accept these kinds of explanations? If you have the time, here’s Damasio’s TED talk on consciousness: I have read some of Damasio’s books. organism, based on its relationship to objects. If we hear a sound, a similar audio image will be formed in the audio processing centers, and so on for all the other senses. 2) Consciousness is more than wakefulness or attentiveness. a pre-conscious state, which provides a reference for the core self and I'll also remove the tag. Necessary condition: there is a ‘counting’ device (counting strews, abacus or Turing computer). But CDZs aren’t just for generating images.

I’ve recently started hearing the word “allostasis” as a substitute for “homeostasis”. A lot of computationists think that brain processing happens in a language of its own, sometimes called “mentalese.” But I personally see it as very unlikely. Based on that review (thanks! organism's awareness. I’m curious what the differences are between homeostasis and balanced equilibrium. more evolved is the second layer of Damasio's theory, Core There’s also a danger here of viewing the images as passively created by the senses, when in reality, particularly for vision, an enormous amount of active modeling is taking place from the retina on back to the brain, with even our immediate perceptions heavily influenced by preexisting associations. Necessary condition: the ability to distinguish self from others. This level could not exist The language of thought is the language of neurons and synapses. The second step for us is that we feel the emotion though the body image, which influences our inclinations, but leaves us with the power to alter the inclined actions, a capability the autobiographical self contributes toward and a possibly adaptive reason for its existence. Damasio envisions CDZs existing in the “many thousands”, but there being a few dozen CDRegions. layer emerges as Extended Consciousness. The brain simply translates the onslaught of all colors as white. interaction with internal or external stimulus. This survival impulse is shared by all life, even the simplest single celled organisms. For the universal counting device, see http://www.prequark.org/Biolife.htm ). One possible answer along these lines is Michael Graziano’s Attention Schema Theory, which I’ve addressed it other posts: https://selfawarepatterns.com/2014/10/16/the-attention-schema-theory-of-consciousness-deserves-your-attention/ We already know a lot more than most people realize. This survival impulse is shared by all life, even the simplest single celled organisms. Here is the missing parts. The dispositional areas are, evolutionarily, far more ancient, but even the brainstem has low resolution image making portions. I don’t see it that way, but I can understand why many people do. Yet they appear to enjoy sensations, music, have favorite caregivers, and generally have a sort of primal existence. How and from what is our experience of color produced, for example? On top of the proto-self is the core self. that are representative of the body's internal state. A quick warning: I didn’t find this to be easy reading. It might be best thought of as a CDRegion at the center of a galaxy of CDRegions. If perception is to be effective in leading an organism to make effective decisions, then we can ask how should they feel? Why, A Medley of Potpourri is just what it says; various thoughts, opinions, ruminations, and contemplations on a variety of subjects. We are conscious of a portion of the processing that happens in the image areas, but never conscious of what happens in the dispositional areas. It seems . I find the core assertion of defending homeostasis as somewhat suspect though. For the naive explanation for the selfness is the Pauli’s exclusion principle that every Fermion carries a unique ID number while the whole explanation is more complicated. A predator or some other kind of threat? I agree on the language / symbolism preoccupation. Change ), You are commenting using your Google account. A feeling arises when the organism becomes aware of the It doesn’t seem to address the difference between what happens in our conscious experience and what happens subconsciously, or of the experience of experience. the current status of the body's responses to environmental changes. 97% of the observable universe is forever unreachable, here are some diagrams showing the CDZ hierarchies in action, https://selfawarepatterns.com/2014/10/16/the-attention-schema-theory-of-consciousness-deserves-your-attention/, Types of sensory consciousness | SelfAwarePatterns, The system components of pain | SelfAwarePatterns, The seven attributes of minimal consciousness | SelfAwarePatterns, Talking across the boundary of the epiphany, Mind uploading and the philosophy of self. Both protoself and core consciousness, and, by the way, extended consciousness should all be sections in a new article that might be called Damasio's theory of consciousness. Three important concepts in this theory are 'emotion', 'feeling' and 'feeling a feeling' (or core consciousness). Post was not sent - check your email addresses! The neuro-anatomy of 100 billion neurons and 100 trillion synapses approaches the complexity of many galaxies – ineffable. I am skeptical, though.
