No but here are links to the books referred to I believe.@Soupie: have you been able to follow up on these?
Here there is good news. We have substantial progress on the mindbody
problem under conscious realism, and there are real scientific theories.
We now have mathematically precise theories about how one type
of conscious agent, namely human observers, might construct the visual
shapes, colors, textures, and motions of objects (see, e.g., Hoffman 1998;
Knill and Richards 1996, Palmer 1999).
When I said "tripped up", I meant literally tripped up in his speech. Not being able to make sense of something in one's mind will often do that when one is trying to explain what they mean in a coherent manner. It demonstrates a level of confusion. Or maybe he was feeling like he was going to sneeze or something ... LOL. I dunno. I just thought I'd point it out. See it for yourself in the direct quote and the video.Hm, no, I'm not seeing where he gets tripped up. That is, I'm not seeing any logical inconsistency.
That wording ( 5 ) appears to conflate material reality ( the objective universe separate from ourselves ) with mental reality ( the subjective experience of being in the objective universe ). Phenomenal objects; e.g. a Ferrari in ones driveway, aren't made of the same type of physicality as their mental counterparts ( the Ferrari we imagine is in our driveway ). For reasons that seem more obvious to bankers than philosophers, the former will also make it much easier to get a car loan than the latter ... LOL. So I'm not saying that, "conscious experience is not something". I'm saying that it is it's own special type of something that while physical in nature, is of a type that is distinct from all the other types of physical things.Perhaps it's just Are you suggesting that conscious experience is not "something?" (Indeed a very good case can be made (is being made) that it's the ultimate something.)
(1) Objective Reality consists of systems of interacting Conscious Agents
(2) Evolved systems of Conscious Agents perceive Objective Reality (other Conscious Agents) via a User Interface.
(3) The human UI manifests phenomenal objects such as atoms, molecules, cells, organisms, etc.
(4) These phenomenal objects must be taken seriously, but not literally.
(5) Thus, it can be said that consciousness (Conscious Agents) is fundamental and matter (phenomenal objects) is derivative.
On this, I suggest that if you haven't already done so, that you first review: Brain in a Vat Argument, The | Internet Encyclopedia of PhilosophyIndeed, how do we know they're not just manifestations of our own consciousness?
Actually, when describing his Conscious Realism Thesis, he does quite literally replace spacetime and the material world with consciousness only. It is I who is suggesting that doing so is where he goes over the ledge. If however, you don't go over that ledge with him, then there is usefulness in the way he formulates the hypothetical connections between conscious agents.Do these hypothesized agents have to exist within something? What Hoffman is saying is that human percepts and concepts such as spacetime need to be taken seriously but not literally. Thus, the logic of our world (subjective reality) need not apply to what-is (objective reality).
Conscious Agents exist because a philosopher ( Shaun Gallagher ) conceived them.(1) Why do Conscious Agent(s) exist?
Conscious agents are assumed to interact for the purpose of thought experiments about consciousness.(2) Why do they interact?
Conscious agents are assumed to interact by affecting the experiences of other conscious agents.(3) How do they interact?
A system of conscious agents may or may not share one POV depending on what one means by "POV" and "experience"(4) Does a system of Conscious Agents share one POV? Why or why not?
I'm sure you do. There are different ways of answering the questions depending on context. I've used one particular context that may seem a bit facetious on the surface, but can be taken quite seriously as well. It all makes for interesting discussion. Why do you feel that you ( as a conscious agent ) exist?I've got my own thoughts and hypothetical answers to these questions.
Hey, if we've kicked the can down the road, then we've gotten a little further down the road and shared a small part of the journey. It's all good .One could argue we've just kicked the can down the road, but I disagree. In my own very limited time and effort thinking about the MBP, this is the most promising model I've encountered.
As McGinn
(1989) puts it,
I think we have to challenge the underscored portion of McGinn's sentence. How do we"know that brains are the de facto causal basis of consciousness" if we cannot prove it, i.e., demonstrate it, which McGinn goes on to recognize?“we know that brains are the de facto causal basis of consciousness, but we have, it seems, no understanding whatever of how this can be so.”
He provides two very good reasons for why the world "out there" should be discarded and replaced with consciousness.On logical consistency, what I'm saying is that the CRT ( Conscious Realism Thesis ) seems logical because he includes "the World" in the theorem, and therefore it seems as though he recognizes that there is a world out there beyond our selves; but in the definition of Conscious Realism, that world ( W ) consists only of other conscious agents, which makes the logic circular and therefore although internally consistent, doesn't explain why the world "out there" should be discarded from the thesis and simply replaced with conscious agents.
Ill have to re-watch the video you reference. In all the material ive encountered, Hoffman makes it very clear that photons are part of the UI and thus not a fundamental denizen of objective reality.Neither does it explain how stimuli such as photons ( his own example ) can come into the eye as a stimulus response and give rise in some way to the MUI icons. The CRT ( basically the same as subjective idealism ), would suggest that the photons that come into the eye are being sent from other conscious agents rather than any objective light source. I don't think you'll find many who think that idea should be taken seriously. I'm just trying to save you some time here in your search, but by all means feel free to continue pondering the implications for yourself. I think you'll come to the same conclusion.
You're presupposing that objective reality is material. How do you know that objective reality is material? That is, how do you know that objective reality is composed of quarks, electrons, photons, atoms, molecules, cells, etc?That wording ( 5 ) appears to conflate material reality ( the objective universe separate from ourselves ) with mental reality ( the subjective experience of being in the objective universe ).

We also do not know how McGinn is defining 'consciousness' in that sentence. Is he thinking in that statement only of consciousness as awareness of self and environment in waking states or is he thinking of consciousness as a spectrum of experience known {comprehended} prereflectively as well as reflectively in the evolution and development of consciousness within the evolution of species of life. In physical evolution, living species develop increasing levels of consciousness and increasing powers of recognizing their situatedness relative to what appears as environment and 'world'. In humans, the philosophizing species, consciousness demonstrates the further capability to reflect on its own nature relative to
a) the physical being of the things-that-are, and
b) the developed social/cultural, historical being constructed out of the activities of conscious beings in situation].
What is refreshing in Hoffman's thinking, and moreso in that of Christopher Fuchs (see the Quanta interview with him that I posted last night), is their apparent ability to recognize that consciousness is broad, deep, and multileveled, and exceeds the possibilities of description offered by neuroscientists who presuppose that brain functions alone can account for consciousness. Phenomenological philosophy recognizes that human consciousness could not arise without existing in a physical world, that consciousness stands both within and at a slight distance from the natural physical world out of which it has evolved. This is the meaning of what Evan Thompson writes in the NDPR review quoted several times above:
“… As Havi Carel and Darian Meacham state in their "Editors' Introduction," "whereas naturalism takes objectivity as its point of departure, phenomenology asks how objectivity is constituted in the first place" (p. 3).
We can now state the objection that phenomenology makes to the methodological component of scientific naturalism. Phenomenology charges that scientific naturalism is oblivious to the priority of the world as the space of meaning and does not recognize the need for specifically philosophical methods, especially transcendental and existential phenomenological ones, for investigating and understanding it.
Many of the essays take this phenomenological charge against naturalism as the background against which to consider whether there may be ways to revise phenomenology and naturalism in order to make them compatible or somehow reconcilable. Central to these discussions is the problem of consciousness. One approach, known as the "naturalizing phenomenology" project (Petitot et al. 1999; Roy et al. 1999), seeks to absorb phenomenological analyses of consciousness into some kind of naturalistic framework. Another approach, "phenomenologizing nature," uses phenomenology to enrich our understanding of nature, especially living being and the body, in order to do justice to consciousness as a natural phenomenon. Ultimately, both strategies are necessary and must be pursued in a complementary and mutually supporting way, if phenomenology is not to be reduced to or eliminated in favor of scientific naturalism, and if naturalism is not to be rejected in favor of metaphysically dualist or idealist forms of phenomenology.”
But Hoffman seems to be comfortably (even blissfully) unaware of phenomenological philosophy and recent developments in biological research concerning protoconsciousness as rooted in the affectivity of primordial organisms, and thus unaware of the ways in which affective neuroscience and phenomenology increase our understanding of the evolution of embodied prereflective consciousness that enables the development of reflective consciousness and mind. Indeed, Hoffman builds his ambitious hypothesis on a mechanical theory of visual processing (not a broad investigation of perception involving the complement of sensory experience and sensory-motor contingencies), and never connects his notion of perception to either consciousness or mind. His ideas might range over a variety of topics [many not adequately connected to his core hypothesis], but his approach remains reductive and also fanciful.
For example, Hoffman writes (quoted in post 139):
"But what is your relational brain? Does it resemble your phenomenal brain? There’s no reason to suppose it does. In fact, as we saw with the volleyball, there’s no reason to suppose that the nature of the phenomenal brain in any way constrains the nature of the relational brain. Your phenomenal brain is simply a graphical interface that allows you to interact with your relational brain, whatever that relational brain might be. And all that’s required of a graphical interface is that it be systematically related to what it represents."
Hoffman's profound error is in assuming that something he calls the 'relational brain' can be distinguished from what he calls the 'phenomenal brain', failing to comprehend the phenomenological insight that the phenomenal appearances by which we have awareness of and access to actual 'things' in our environment also disclose to us our (ambiguous) relation to those things, to that environment -- this disclosure constituting the existential situation that Heidegger is at pains to articulate in Being and Time, one of the most influential texts in modern philosophy. Well after all, Hoffman is not a philosopher. But then why should we take him seriously as a philosopher? The next question is, should we take him seriously as a scientist?
McGinn's claim above, that "brains are the de facto causal basis of consciousness," also rests on incomplete reading of [or perhaps no reading of] phenomenological philosophy. He's not alone in that, which is unfortunate since it is this 100-year-old school of philosophy, supplemented by Panksepp's new Affective Neuroscience, that seals consciousness and mind back into the evolution of physical nature from which both capacities arise.

{quoting Hoffman} "Third, although science is laudably conservative, yet when pushed to the wall by recalcitrant data and impotent theories, scientists have repeatedly proved willing to reexamine dearly held presuppositions and to revise or jettison the ineffectual in favor of unorthodox assumptions, provided that these assumptions permit the construction of explanatory theories that answer to data."
He provides two very good reasons for why the world "out there" should be discarded and replaced with consciousness.
(1) The mind-body problem. A very serious scientific problem that scientists havent gotten close to resolving using the physicalist paradigm.
(2) Hoffman presents a very good argument that the Hypothesis of Faithful Depiction is wrong. Thus, the apparently physical world that appears to us in experience need not be a faithful depiction of objective reality and most likely is not.
Ill have to re-watch the video you reference. In all the material ive encountered, Hoffman makes it very clear that photons are part of the UI and thus not a fundamental denizen of objective reality.
So while we may subjectively perceive photons to stimulate cells in the eye, understand that perception hasn't evolved to disclose objective reality to us veridically, only adaptively. It follows then that the photons and cells we perceive are icons—quite rich in their own right—of more complex processes taking place in objective reality.
In order for you to overcome this problem, Ufology, I think you'll need to defend the Hypothesis of Faithful Depiction.
You're presupposing that objective reality is material. How do you know that objective reality is material? That is, how do you know that objective reality is composed of quarks, electrons, photons, atoms, molecules, cells, etc?
Also, you continue to insist that consciousness is physical but you provide no model—not even a conceptual model—that can begin to support this claim.
A 100-year-old school of philosophy that hasn't made any progress in resolving the MBP.
And while there are currently ongoing attempts to naturalize phenomenology a la Thompson, a resolution of the MBP still eludes us.
As noted Hoffman's thesis of Conscious Realism is certainly not the complete picture, but his desire to branch away from physicalism/emergentism is certainly warranted.

I should have added that, your having not as yet read any phenomenological philosophy, I would not have expected you to recognize the progress it has made [particularly in Merleau-Ponty's works] in demonstrating the intimate and inescapable relationship of mind and body. While you wait for a full resolution of the mind-body problem you might find some satisfaction in finally reading this philosophy.
Not everyone accepts that the mind body problem is a legitimate "problem". Searle calls it a "false dichotomy" and similarly, I would say that the mind-body problem is a scientific problem to the same extent that there's a magnet-magnetism problem or a mass-gravitation problem. That's because science deals with the properties and behavior of the extant, not the nature of existence itself. That's the job of philosophers So the mind-body problem is only a "problem" for philosophers who choose to look at the co-existence of the mind and body as "problematic" in their context, and therefore since the nature of the problem in philosophical terms it's not relevant to science, I would question the relevance of your comment. Searle has no problem saying that we can take an objective and scientific approach to studying subjective experience. I agree.He provides two very good reasons for why the world "out there" should be discarded and replaced with consciousness.
(1) The mind-body problem. A very serious scientific problem that scientists havent gotten close to resolving using the physicalist paradigm.
We know our senses can be fooled and that what we perceive is a mental construct rather than an experience of the actual object being perceived, but this translates to: "Objective external reality isn't what we perceive it to be." not to "There is no objective external reality."(2) Hoffman presents a very good argument that the Hypothesis of Faithful Depiction is wrong. Thus, the apparently physical world that appears to us in experience need not be a faithful depiction of objective reality and most likely is not.

Hoffman makes it quite clear at the start of the video that we don't perceive photons. We perceive the resulting mental experience that the photons initiate via the biology of our eyes and visual processing centers in the brain. He even has pictures that explain this in no uncertain terms. This is just fine. It's where he wanders off in his suggestion that all reality including spacetime and atoms and so on are also conscious constructs that he falls off the ledge.So while we may subjectively perceive photons to stimulate cells in the eye, understand that perception hasn't evolved to disclose objective reality to us veridically, only adaptively.

If you're alluding to the mind-body problem, as the "problem", then it's not a "problem" for me because I accept that there are both minds and bodies and that they coexist in the universe as physical, in the sense that physical is not to be confused with "material", as in material vs. non-material. So for me, unless you are alluding to a different problem, there is no "problem to overcome". There are only relationships to study.In order for you to overcome this problem, Ufology, I think you'll need to defend the Hypothesis of Faithful Depiction.
Not quite. Basically, I'm presupposing that all reality is physical in the sense that that everything that exists has properties and behaviors that lead to arbitrary relationships between them. This is a physicalist ( as opposed to materialist ) perspective because the "physical" isn't simply what we perceive to be "material". To be more specific there are branches of Physicalism and although I'm not sure where the philosophers would place me if they were able to see inside my head, it seems that I'm somewhere off in the realm of Emergentism. This seems to be a good overview: http://www.brynmawr.edu/biology/emergence/stephan.pdfYou're presupposing that objective reality is material. How do you know that objective reality is material? That is, how do you know that objective reality is composed of quarks, electrons, photons, atoms, molecules, cells, etc?
I don't actually "insist" that consciousness is physical but I do look at it as a physical phenomenon in the same way as we look at other phenomena like gravity, magnetism, etc. as being physical phenomena, and are equally perplexed as to the fundamental nature of their existence, but nevertheless have been able to map out their relationships to other materials and phenomena in a way that has proven to be very useful in many practical applications.Also, you continue to insist that consciousness is physical but you provide no model—not even a conceptual model—that can begin to support this claim.

I'm not sure what would qualify in your comment as "beginning to support this claim.", but I would say that the number of posts I've contributed more than constitute a "beginning" and most are either based on or include accepted scientific information, particularly those that directly correlate brain function to conscious experience, and those that explore the idea that consciousness is an emergent property.
I'll close this post by saying that somewhat ironically, even though Chalmers criticizes emergentism, he also favors the idea that consciousness is something fundamental, which is also a feature of emergent phenomena. So Chalmers is actually endorsing emergentism, and his objection to it because it doesn't explain why consciousness should be accompanied by brain material and EM fields, is irrelevant. We may never be able to explain why consciousness should be accompanied by brain material and EM fields just like we may never know why objects should have mass.
Why type questions imply some purpose, and purpose is a concept that only has meaning to entities that are capable of understanding that concept, which is only a very small subset of all which appears to exist. So there is no reason "why" many things happen unless we invoke some omniscient God and claim it's all because of his or her divine will. In short: In the absence of a creator there is no "why" answer for fundamental phenomena. There is simply acceptance that it exists. Feynman goes through a rather long winded and painful explanation of this below as well:
