  >And to clarify, I believe the above would be nonsense for the non-Hard Problem which is clearly related to cognition—but I'm only speaking of The Hard Problem. People can give after-the-fact subjective reports of what, if anything, they were experiencing in non-communicative states (for lack of a better term). They can tell us that something was "going on" in their head while they were dreaming, or that they don't recall experiencing anything while being in a coma or being "dead" for a few minutes before being resuscitated. We seem to agree that this is the convenient version of consciousness that people are able to communicate about. And we can look at what brain states match up with these reports -- reports of hard consciousness -- and find that certain brain configurations and activities seem to always be there when hard consciousness is there. But perhaps, you might say, a person who doesn't recall any experiences during a coma actually had experiences then, too. But just doesn't know it and/or weren't able to communicate about it. So on the one hand, the kinds of consciousness a person is able to communicate about is corroborated by some sort of interesting brain activity. And the other kind of consciousness that they can't communicate about, the kind posed by a philosopher, isn't corroborated by anything. That starts to look like a "consciousness of the gaps" problem. And this is without even taking into account aforementioned things like sophisticated behavior and other biological clues which you say are "just" the non-hard problem. There again, I think that these are important evidence, and that excluding them is borrowing from a conclusion to pay for an argument. It's also more elegant from the perspective of simple explanation. The amount of explanatory debt one incurs by taking on the construction project of a parallel, universe-spanning medium inhabited by consciousness is enormous, and there's significant risk that the investment won't pay off. >I think we're talking about different things here. I am specifically talking about people conflating the Hard Problem of consciousness with the non-Hard Problem of consciousness. Or do you mean to say that the two problems are the same and that the designation of 'Hard Problem' as something separate is vacuous? The hard problem is real in that it demands an explanation that is more than just citing brain activity or waving it away as an illusion. But the notion that physical stuff is automatically about something other than the hard problem is baking your conclusion into the definition of the problem. There are certainly all kinds of non-hard things physics/biology explains, but they may yet explain hard things too, provided a compelling enough argument can be made. >Instead, I think if you follow the problem of trying to define qualia far enough, you end up running into my fabric of the universe situation My problem with talking this way is that, if I were to do the same thing, I would end up saying that following the problem of qualia far enough leads to somethingorother about circuits of synapse firing and its intimate connection to experiences, thus the problem is "really" about those things, and someone talking about a universal medium shared by consciousness and physics but independent from them is talking about the wrong thing. But in a way I think you are right,because I think at the end of the day an adequate answer does have to be about finding some ontological level, some "medium", on which consciousness and physics can be understood to be continuous with each other. I just happen to think that that medium is physics, and that we will have to get comfortable with the idea that there are robustly physical answers to questions of what are qualia and what is consciousness. I.e. the idea that what manifests itself as experiences are at some raw level, sheer, nakedly physical events witnessed by other physical events which we call brain activity.

    > I just happen to think that that medium is physics Could you clarify what you mean by that? Physics is branch of knowledge, a collection of descriptions of regularities in material structures evolving in time. I don't see how a collection of descriptions can be the medium in which subjectivity/qualia exist. See what I mean? Or you mean what's referred to in those descriptions? If so, I see a difficulty in it because you just get back to the same subjectivity/qualia problem. I mean, what is being referred to in those descriptions? Our starting point for what physics is talking about is subjectivity—the only thing we have direct empirical contact with. Then we make abstractions on top of it so that various parts are grouped into 'objects' etc. (that grouping is largely subconscious), and then physics comes into play in giving descriptions of regularities in the time evolution of categories of those objects. But none of that deals with what the objects being discussed are, it just just talks about how a selection of characteristics which happen to be useful to use change in time. I know some people believe the best we can do is say that what something is is the collection of things we say about it. So, the things being referred to in physics are the regularities in certain of their attributes, e.g. the measurements we make of their mass and velocity, and the forces being applied to them or which they are applying etc. Personally that sounds like a cop-out, though granted, it's at least an attempt at a pragmatic cop-out: after all, what's the point in entertaining the idea that there's more to the thing if we know we can never access it/talk about it. But here's the value: if you just admit the boundaries to your knowledge, your taking a more realistic account of things (the alternative of pretending the boundaries aren't there can only lead to mistakes). In that case, we have not discovered what the things are which are referred to by physics, we have just charted regularities in certain attributes we care about (it's also important to note that we invented those attributes, and which set of attributes we deem to be the intrinsic/essential characteristics have a degree of arbitrariness to them since multiple equivalent formulations exist—e.g. reformulations of Newtonian mechanics which give the same outputs for the same inputs but in which the notion of 'force' does not exist, or relativistic/quantum mechanics of course, though that's moving beyond strict reformulation). Edit: I clarified a number of things on re-reading a few minutes after posting!
