Galen Strawson's realistic materialism is one of the rare instances today of panexperiential monism classed as physical, if not a neutral monism in disguise.
I guess that the phrase 'panexperiential monism' can be spun in both idealist and neutral-monist/double-aspect ways. The difference between neutral-monist and double-aspect, in turn, may or many not revolve around idea that 'neutral-monist' suggests kind of a phenomenalism, describing all the various contents of experience as a single class. While 'double-aspect' is more realist, talking about the contents of nature itself having both physical and mental properies.
The thing is, I don't think that Rav is suggesting a phenomenalism, exactly. He doesn' seem to be trying to define the world as the contents of experience. That kind of theory slides into idealism, unless we go Buddhist and decide that minds are just as much a construction from experience as matter, leaving us with experience as reality's basic neutral monistic stuff.
I think that Rav accepts the idea that the fundamental components of physics really are ontological somehow, hence the 'physicalism'. If so, I would definitely agree with him on that. Where Rav and I appear to differ, is that he seemingly sees an insurmountable problem in deriving phenomenal qualitative experience from the arid mathematical world described by physics. So he apparently is hypothesizing that the qualitative experiential stuff might already be down there, somewhere, in the stuff of physics, arguing in effect that matter already has mental properties. I don't buy that part and prefer to imagine qualitative experience as emergent from the behavior of information processing systems.
His [Strawson's] stance at least partly seems to consist of the assertion that materialism and the experiential character of consciousness didn't become separate until a few centuries ago;
That may or may not be true if 'materialism' and 'the experiential character of consciousness' refer to philosophical concepts. (I'm certain that the ontology of the universe itself didn't change.) Our modern Western philosophy of mind didn't start to take form until a few hundred years ago. Many of the earlier medievals, Greeks and (especially) the Indians made similar distinctions, but not in precisely the way that we do today. It's hard for me to be sure how dramatically modern concepts differ from the earlier ideas.
and that conclusion of matter being a substance that (normally) lacks any phenomenal manifestation of itself whatsoever was, and still is, speculation or possibility treated as certainty -- which generates issues like Chalmers' hard-problem.
I'm not a devotee of Chalmers', but gather that his 'hard problem' is essentially this -- how do we get experiential qualia like red out of the world of physics? Chalmers wants to argue that he can generate a disproof of physicalism from that intuition. I'm certainly not convinced of that.
Strawson - "Many take the [mind-body problem] to be the problem of how mental phenomena can be physical phenomena given what we already know about the nature of the physical. But those who think this are already lost. For the fact is that we have no good reason to think that we know anything about the physical that gives us any reason to find any problem in the idea that mental phenomena are physical phenomena.” --from Neutral Monism, Stanford Encyclopedia of Philosophy entry
I don't understand that. Perhaps I'm missing the context.
Strawson - "Once upon a time, not so long ago, no one thought that there was a mind-body problem. No one thought consciousness was a special mystery and they were right.
I think that Chalmers' 'hard problem' is probably a pseudo-problem, the result of misconceptualizing things. (Such as imagining qualia as if they were physical things, except arguing that they are non-physical.) But like Rav said earlier, I'm not prepared to present a fully formed explanation and defense of why I'm inclined to think that. It's still a work-in-progress.
But I don't think that Galen Strawson would agree with me.
The sense of difficulty arose only about 400 years ago and for a very specific reason: people began to think they knew what matter was. They thought (very briefly) that matter consisted entirely of grainy particles with various shapes bumping into one another. This was classical contact mechanics, 'the corpuscularian philosophy', and it gave rise to a conundrum. If this is all that matter is, how can it be the basis of or give rise to mind or consciousness? It seemed clear, as Shakespeare observed, that 'when the brains were out, the man would die'.
". . . But how could the wholly material brain be the seat of consciousness? Conclusion: consciousness can't be physical, so we must have immaterial souls. Descartes went that way (albeit with secret doubts). So did many others. The mind-body problem came into existence. Hobbes wasn't bothered, though, in 1651. He didn't see why consciousness couldn't be entirely physical. And that, presumably, is because he didn't make the Great Mistake: he didn't think that the corpuscularian philosophy told us the whole truth about the nature of matter. And he was right. Matter is 'much odder than we thought', as Auden said in 1939, and it's got even odder since."
Yeah, that's probably true, but I don't think that it's very helpful.
We can and probably should replace 17th century corpuscularian physics with 20'th century relativity and quantum mechanics, but does that really make this problem of where the phenomenal quality red is to be found in the world of fundamental physics just go away? Does updating physics 300 years bring us any closer to resolving that difficulty, without our somehow putting redness into physics to begin with and waving the magic wand of quantum weirdness over it? Doing that is physicalist panexperientialism, basically. It isn't very much of a solution, just a resolution by fiat -- Red's already in there, so that's it, nothing to look at here, problem solved, move on.
People who think that way are looking for the answer in the wrong place in my opinion. At the wrong level of abstraction, we might say. It's as if we tried to explain a computer's functions in terms of the physics of computer chips. Sure, the chips and similar hardware represent the ontological level of the machine, but the functions that the machine perform center on information and what's being done to it. That's the level that I think that we need to look at if we ever hope to understand how our own experience emerges. Qualia aren't, and don't need to be, included in the fundamental inventory of physics.
