Panpsychism has always been a problem for physicalism because it seems to be decidedly not what physicalists want to posit, but at the same time it is in no way ruled out by mainstream physicalism. — Count Timothy von Icarus
Partly because no physicalism that precludes panpsychism has been developed that doesn't seem to spawn massive problems for the theorist. — Count Timothy von Icarus
To be honest, it's really weird to me how physicalism is the most popular ontology writ large, but in the context of metaphysics as a specialty it's like a battleship that's taken direct multiple direct torpedo hits, is listing to one side, its magazine blew, and it looks liable to break in half. — Count Timothy von Icarus
I don't see any real problem. Panpsychism seems like nothing more than an unfalsifiable hypothesis that has no significant explanatory value, and Ockham razor seems like sufficient justification for dismissing panpsychism. From my perspective panpsychism doesn't seem to present any more challenge than solipsism.
This seems to me, more a matter of unrealistic expectations on the part of critics of physicalism, than it seems a problem for physicalism. Brains are enormously complex, and I say this as an electrical engineer who routinely deals with highly complex systems. Yes there is a huge way to go in developing a understanding of how brains instantiate minds, and no guarantee that human minds are up to the task of developing something approaching an ultimate explanatory theory. However, substantial explanatory progress has been made over my lifetime, and that progress is ongoing. I don't see how anything similar can be claimed for panpsychism.
In any case, I'm interested in hearing more about what you see as "massive problems" for physicalism.
But the most influential objection to supervenience physicalism (and to modal formulations generally) is what might be called the sufficiency problem. This alleges that, while (1) articulates a necessary condition for physicalism it does not provide a sufficient condition. The underlying rationale is that, intuitively one thing can supervene on another and yet be of a completely different nature. To use Fine’s famous (1994) example, consider the difference between Socrates and his singleton set, the set that contains only Socrates as a member. The facts about the set supervene on the facts about Socrates; any world that is like ours in respect of the existence of Socrates is like ours in respect of the existence of his singleton set. And yet the set is quite different from Socrates. This in turn raises the possibility that something might be of a completely different nature from the physical and nevertheless supervene on it.
One may bring out this objection further by considering positions in philosophy which entail supervenience and yet deny physicalism. A good example is necessitation dualism, which is an approach that weaves together elements of both physicalism and its traditional rival, dualism. On the one hand, the necessitation dualist wants to say that mental facts and physical facts are metaphysically distinct—just as a standard dualist does. On the other hand, the necessitation dualist wants to agree with the physicalist that mental facts are necessitated by, and supervene on, the physical facts. If this sort of position is coherent, (1) does not articulate a sufficient condition for physicalism. For if necessitation dualism is true, any physical duplicate of the actual world is a duplicate simpliciter. And yet, if dualism of any sort is true, including necessitation dualism, physicalism is false.
A final topic that I will consider is that of supervenience. The intuition of supervenience is that higher level phenomena cannot differ unless their supporting lower-level phenomena also differ. There may be something correct in this intuition, but a process metaphysics puts at least standard ways of construing supervenience into question too.
Most commonly, a supervenience base — that upon which some higher-level phenomena are supposed to be supervenient — is defined in terms of the particles and their properties, and perhaps the relations among them, that are the mereological constituents of the supervenient system [Kim, 1991; 1998]. Within a particle framework, and so long as the canonical examples considered are energy well stabilities, this might appear to make sense.
But at least three considerations overturn such an approach. First, local versions of supervenience cannot handle relational phenomena — e.g., the longest pencil in the box may lose the status of being longest pencil even though nothing about the pencil itself changes. Just put a longer pencil into the box. Being the longest pencil in the box is not often of crucial importance, but other relational phenomena are. Being in a far from equilibrium relation to the environment, for example, is a relational kind of property that similarly cannot be construed as being locally supervenient. And it is a property of fundamental importance to much of our worlds — including, not insignificantly, ourselves.
A second consideration is that far from equilibrium process organizations, such as a candle flame, require ongoing exchanges with that environment in order to maintain their far from equilibrium conditions. There is no fixed set of particles, even within a nominally particle view, that mereologically constitutes the flame.
A third, related consideration is the point made above about boundaries. Issues of boundary are not clear with respect to processes, and not all processes have clear boundaries of several differentiable sorts - and, if they do have two or more of them, they are not necessarily co-extensive. But, if boundaries are not clear, then what could constitute a supervenience base is also not clear.
Supervenience is an example of a contemporary notion that has been rendered in particle terms, and that cannot be simply translated into a process metaphysical framework [Bickhard, 2000; 2004]. More generally, a process framework puts many classical metaphysical assumptions into question.

A third problem, which we mentioned briefly above, is the problem of abstracta (Rabin 2020). This concerns the status within physicalism of abstract objects, i.e., entities apparently not located in space and time, such as numbers, properties and relations, or propositions.
To see the problem, suppose that abstract objects, if they exist, exist necessarily, i.e., in all possible worlds. If physicalism is true, then the facts about such objects must either be physical facts, or else bear a particular relation (grounding, realisation) to the physical. But on the face of it, that is not so. Can one really say that 5+7=12, for example, is realised in, or holds in virtue of, some arrangement of atoms and void? Or can one say that it itself is a physical fact or a fundamental physical fact? If not, physicalism is false: the property of being such that 5+7=12 obtains the actual world but is neither identical to, nor grounded in or realized by, any physical property. (Sometimes the problem of abstracta is formulated as concerning, not abstract objects such as numbers or properties, but the grounding or realization facts themselves; see, e.g, Dasgupta 2015. We will set this aside here.)
There are a number of responses to this problem in the literature; for an overview, see Rabin 2020, see also Dasgupta 2015 and Bennett 2017; for more general discussion of physicalism and abstracta, see Montero 2017, Schneider 2017, and Witmer 2017.
One response points out that, while the problem of abstracta confronts many different versions of physicalism, it does not arise for supervenience physicalism. After all, since numbers exist in all possible worlds, facts about them trivially supervene on the physical; any world identical to the actual world in physical respects will be identical to it in respect of whether 5+7=12, because any world at all is identical to the actual world in that respect! But the difficulty here is that supervenience physicalism seems, as we saw above, too weak anyway. Indeed, one might think that the example of abstracta is simply a different way to bring out that it is too weak.
Another option is to adopt a version of nominalism, and deny the existence of abstracta entirely. The problem with this option is that defending nominalism about mathematics is no easy matter, and in any case nominalism and physicalism are normally thought of as distinct commitments.
A third view, which seems more attractive than either of the two mentioned so far, is to expand the notion of a physical property that is in play in formulations of physicalism. For example, one might treat the properties of abstract objects as topic-neutral in something like the sense discussed in connection with Smart and reductionism above (see section 3.1). Topic-neutral properties have the interesting feature that, while they themselves are not physical, but are capable of being instantiated in what is intuitively a completely physical world, or indeed what is intuitively a completely spiritual world or a world entirely made of water. If so, it becomes possible to understand physicalism so that the reference to ‘physical properties’ within it is understood more correctly as ‘physical or topic-neutral properties’.
I began to "conceptualize reality in terms of information" about 15 years ago, when a quantum physicist --- studying the material foundation of reality --- exclaimed that he had just realized "it's all information!". His, oh-by-the-way exclamation led me back to John A. Wheeler's 1989 "it from bit" postulation*1. What he meant by that cryptic quip is : every-thing (its ; material stuff) in the world can be reduced down to binary information (bits ; mind stuff). That equation of mind & matter would not go down well with committed Materialists though, because it opened the door to such spooky ideas as "mind over matter" (magic).Intriguing! I have at times thought about conceptualizing reality in terms of information. I think I have quite a way to go before I can consider myself to have a precise well-thought out kind of manifesto about what I actually believe about reality or how I should view it. Still have to think out a lot of kinks. — Apustimelogist
Thus, while we can abstract the picture from the photograph, and we can say that there are isomorphisms between different copies of the same image, these are causally irrelevant. — Count Timothy von Icarus
Physicalism says that everything that can be known about seeing red is physical. There is nothing else. Perhaps experiencing red is a different experience than knowing "how red is experienced." This is fine, but it's going to lead you to physicalism with type or predicate dualism (which may or may not be physicalism depending on who you ask).
If physicalism isn't going to fall to Hemple's dilemma and define itself as "just whatever currently has evidential support," it seems like it has to pick a hill to die on, and superveniance is the most obvious hill.
To be fair, I think similar sorts of problems show up for idealism — Count Timothy von Icarus
Information is another abstraction and any notion of information depends on the ability for an observer or detector to make distinctions; information is therefore not really a thing but is something that manifests in the interaction between a stimulus and observer / detector. What this means is that any notion of information would be at least implicitly embodied in the physical processes that enable an observer to make distinctions (e.g. so that I can recognize a photo or a neuron can selectively respond to different inputs): the information is physical, just not in any way independent of an observer. — Apustimelogist
I find it interesting how many materialist/physicalist accounts of the mind assume the very thing they are explaining. This is often called a "hidden dualism" and amongst other things, I take this to mean that the dualism is "hidden" from the arguer.
Often times this looks like a sleight of hand between process/behavior and mental events.
Example: The neuron fires (process/behavioral). The neurons fire (process/behavioral). The networks form (process/behavioral). The sensory tissues/organs are acted upon (process/behavioral). A line or shape is processed in a visual cortex (mental). An object is perceived (mental). An object is recognized (mental). A long-term potentiation (process/behavioral). A memory is accessed (process/behavioral). "Fires together, wires together" (process/behavioral), associating one thing with another (mental).
As you see with these examples, these often are interchanged all the time, leading to a belief one is talking purely behavioral, when in fact it is a mix of process/behavioral and mental. This muddling of the two is where the hidden dualism comes into play. It is this constant category error that trips people up into not understanding any "hard problem". It leads to blind scientism, and a constant not "getting" the problems that arise from philosophy of mind. — schopenhauer1
I don't think there is anything problematic in entertaining both the mental and physical as concepts that we have constructed due to the nature of our brains. — Apustimelogist
What do you mean? — Apustimelogist
I don't see the problem. It seems to me that under your characterization, physicalism would be falsified if there existed any concepts that were not physical: e.g. organisms, economies, mountains. They are all just labels that describe our empirical observations at different scales nd levels of abstraction. I can think of an observer the same way, I just mean more or less something that can respond differently to different inputs. That seems to be the kind of minimal characterization of information processing. — Apustimelogist

My view isn't so much about falsifying qualia but about whether our concepts of qualia and their irreducibility can plausibly arise through information processing. — Apustimelogist
If that is the case then it strongly suggests to me that dualism is an illusion because it would entail epiphenomenalism which is absurd. — Apustimelogist
suggests to me that dualism is an illusion because it would entail epiphenomenalism which is absurd. On the other hand it suggests one might be able to defend the identity between brain processes and qualia even if one cannot be reduced to the other. This would allow a physicalist to defend the notion that everything is physical, or more specifically that nothing extra is needed to describe reality. — Apustimelogist
Yeah and how about that theory? How does it "arise"? "What" is it that is "arisen"? — schopenhauer1
That's only one form of dualism and even that is not entailed in physicalism. Physicalism doesn't have room for mental events other than hidden dualism (has been my premise for a while). — schopenhauer1
I think that isn't much of an argument other than we don't know. That is again, only one form of dualism, and it's one that's prone to physicalist accounts because it starts with the physical causing mental. — schopenhauer1
Emergence does have to be explained here. How is it that emergent properties exist prior to the viewer, and all that. It's bald assertion to just say that "and it emerges", it's about as explanatory as saying, "it's an illusion". — schopenhauer1
Yes, Information is inter-dependent. It's physical, in the sense that it is transmitted from mind to mind via physical vehicles (ink, sound, rhodopsin, etc). But information is also metaphysical, in the sense that Shannon defined it in terms of statistical probability (potential, correlations, not-yet-real).Information is another abstraction and any notion of information depends on the ability for an observer or detector to make distinctions; information is therefore not really a thing but is something that can be characterized in the interaction between a stimulus and observer / detector. What this means is that any notion of information would be at least implicitly embodied in the physical processes that enable an observer to make distinctions (e.g. so that I can recognize a photo or a neuron can selectively respond to different inputs): the information is physical, just not in any way independent of an observer. — Apustimelogist
When an abstraction (abstract belief or hypothetical construct) is treated as if it were a concrete, real event or physical entity — Gnomon
I think the point of the quote is that Abstraction is a function of the Observer's data-filtering belief-forming system. Hence, not so much a Dualism but merely different aspects of the same process : interpreting incoming sensory information. Reality is complicated, but perception automatically simplifies our sensory signals into parcels (e.g. Gestalts), in part by omitting unnecessary data*1; before it appears into consciousness. Observing is Interpreting.Cool stuff, but I think it goes too far. Enthusiasm for the subject doesn't pull the rabbit out of the hat, unfortunately. That is to say abstraction already needs the observer. Abstraction isn't the observer. If it is, then that has to be explained, and like "illusion" or "integration", it all becomes hidden dualisms of begging the question. — schopenhauer1
Well the way I stated it in the OP was meant to just be a counterargument against irreducibility so that a physicalist could use it. But I think my view here is mostly just an argument against dualism. I don't think I am truly a physicalist
I understand that my discussions of the Mind vs Matter question may be difficult to follow, in part because I have no formal training in Philosophy, and partly because most of my knowledge of Information is derived from Quantum Physics instead of Shannon's mathematical theory of communication. Another hurdle in communicating my ideas about a Monistic theory of Mind/Matter is that I have been forced, by the complexity of the content, to coin neologisms (new language) that bundle contrasting concepts into single words : e.g. EnFormAction and Enformy.I actually think I more or less agree with a fair amount you talk about in the last two posts you make about information and the "arms-length" separation of observer, though maybe I would describe it in different language. I definitely do have a different perspective but there is definitely stuff I agree on, I think. — Apustimelogist
That's an interesting way to phrase the "hard problem" of "what it's likeness". A computer can mechanically process information without bothering with mentally processing the mathematical data into personal (self relevant) meanings. Brainy Animals seem to be able to compute likeness (analogies) to some degree (gestures, behaviors), but not to the point of intentionally communicating meanings from mind to mind in the concise packages of intention we call "words".Thus information can process with no "what it's likeness" to it. It is just behavior all the way down. And wherever there is "what it's likeness" happening, "what" then is that as opposed to the other behavior that was going on? Then you are back to a dualism of some sort of mental space that pops out of physical space which is basically the question all over again. — schopenhauer1
