percept is usually understood as the product of mind's interpretation of sensory stimuli, the awareness of an object or event, such as grass outside your window or a car zooming by. This is distinct from the stimulus or the raw sense data (if that's a thing). And it is again distinct from the "what-it-is-likeness" of experience, which is what Nagel, Searle, Chalmers, etc. put forward as the phenomenal experience, or qualia, the thing outside the reach of physical accounting (unless we wave our hands and invoke something like "panpsychism"). (If all this seems confusing, then I've made my point.) — SophistiCat
I think that those are perhaps too many distinctions, which makes the topic more difficult than it needs be. The first sentence you write makes sense to me, and is what I take Russell to be talking about.
"This is distinct from the stimulus or the raw sense data". Why isn't the sensory stimulus raw sense data?
The whole "what it's likeness" is a complication here. It's supposed to point out that "there is something it is like" for a person (you, me, anyone) to see the colour red, or read this sentence. I can see red and am writing and reading this sentence, is there "something it is like to do this"? Sure, I guess, I don't think it says much, but I don't doubt my experiences.
Yes, Chomsky says little about this, outside of mentioning this quote of Russell's or citing Strawson's essays and books, he doesn't see a big problem here.
As far as he is concerned, materialism has been dead since at least Newton, but not for any reasons having to do with the "hard problem." — SophistiCat
Because then it meant that it was an intuitive description of the world - and crucially excluded the mental.
Since that doesn't hold up any longer, then if we want to use the word "physical", we can adopt Strawson's use of the word and say, that the physical is everything that is, unless someone can say way something isn't physical. This includes experience, at the highest grade of certainty.
Or we can say that physicalism is what physics studies and that experience is an illusion or not real. This is incoherent to me, but, it's an option.
By then it becomes terminological, and not too substantive, I think.
To be clear, it's not that consciousness isn't a hard problem - it is - but so is gravity, electromagnetism, creativity, free will, and so on. There isn't
the hard problem, but many.
Well, what the argument means to show is that phenomenal experience (which p-z's hypothetically lack) cannot be accounted for by materialism/physicalism as presently understood, and therefore materialism/physicalism is false/incomplete. (How it does that is what I don't quite understand.) — SophistiCat
That's correct. Not false, simply not all-encompassing.
Why don't they ask for a "physical explanation" of why music makes us feel good? Or a "physical explanation" of why we have dreams? And so on.
It's becomes a bit silly. Physics is the study of abstract properties of matter, and this phenomena are simple structures, nothing as complex as biology. It isn't reasonable to expect it to explain things way outside its purview.
