Okay, I'm not disagreeing with you yet- I just need to make sure we are talking about the same things. I realize this is rather tedious, and I appreciate your patience and help.

BTW I'm making up most of this as I type, so I can't just refer you to an already developed model to save time. Trust me, if I could, I would.

When we talk about general conditions of existence behind apparent reality, that are causing what we can see and measure and experience -- that is metaphysics. It doesn't have to be something spiritual, or non-physical; it doesn't even have to be true about all existence. It could refer just to conditions behind one particular aspect of reality.
Your "behind apparent reality" is my "nature", and your "apparent reality" is my "evidence".
me said:
In other words, physical reality- whatever its "nature"- is evidenced in the WOE. Metaphysical reality- whatever its nature- is evidenced in the WSE.
So you are saying that I shouldn't speak of metaphysical and physical
realities but of metaphysical and physical
models. The models are only using our evidence in such a way as to give us insights into the nature of our evidence- the nature of the reality "behind" our evidence. In other words, the models are used to assign additional meaning to our evidence. One such meaning is physicalness- existence in a physical reality.
To clarify that, let me run through some of my assumptions/definitions. The phrase "conscious experience" can be used individually, collectively, and generally. That is, we can speak of individual, unique experiences, as in "seeing a live tree". After seeing more live trees, we can speak of collective experience, as in "seeing live trees". And after seeing things other than live trees, we can speak of general experience, as in "seeing". Conscious experience is what I mean by evidence.
All evidence is subjective. At least some evidence is objective in addition to being subjective. Evidence becomes objective when two people establish a correspondence between their subjective experience. We can establish this correspondence in several ways: by being in each other's presence and pointing to something, calling what we are pointing to a tree, associating the verbal word tree with the written word tree, etc. This is where signs and sign systems (chains of evidence) come in- signs are the mechanisms of establishing correspondence; being in each other's presence and pointing to something, calling what we are pointing to a tree, and associating the verbal word tree with the written word tree are all instances of creating and using signs. And tieing those signs together creates a sign system.
Perhaps this seems like I'm going too far back, but what are models if not sign systems, chains of evidence? A physical or metaphysical model can be explicitly and precisely described by explicitly and precisely describing the chain of evidence- each sign that is used in the model and the connections between them. Doing this for each model would be a monumental task, but I suspect much of the process can be generalized. This is similar to what is done in formal logic, except that semiotics goes further. For instance, logic takes certain terms as undefined. The term "number" may be left undefined in some formal logic system. But the term "number" is part of a sign- the signifier. Semiotics acknowledges what logic does not or cannot- that the term "number"
means something to the person using it- more than it means in the formal logic system; A formal sign system can describe that meaning- the signified- and trace that meaning back to a piece of individual, collective, or general evidence and make apparent whether that evidence is objective or not.
This tracking of meaning could be important in describing a person's reasoning as a formal system. What does the term "number" mean to the mathematician using it? Maybe this is why Penrose fails in trying to model human reasoning as a sound formal system- er, sorry, I have several things going on in my head right now- I don't mean to let them all intrude here. I'll stop this train and respond to the rest of your post. I just have to say that I have a strong suspicion that the distinction between individual, collective, and general evidence is the crucial distinction to make, and signifying individual evidence is the crucial step.
If, for example, some kind of huge or omnipresent consciousness has been involved in the formation of the universe, how do we model it?
What I am suggesting is that if someone has experienced this omnipresent consciousness, that person can use a formal sign system to model it, making the model more than purely speculative. Formal and informal sign systems are used when someone describes the taste of something to someone who has never tasted it. And when someone describes a perfect circle to someone else. And when two people agree about the color of a shirt or the mass of a photon. It's all the same process of linking together signs. Part of the process has already been formalized by logic. Part of the process has already been accepted by physical science. But logic stops short of incorporating all the signified parts of the signs. And physical science stops short of incorporating evidence not available to the senses. So you just need to create a model that uses logical and scientific methods and incorporates what they do not. I think a formal sign system is just the thing to do it. You can then test the system for soundness, completeness, etc. Well, I suspect you would be able to, at least. I haven't actually worked all of this out- I'm developing this idea as I'm writing.
What is consciousness? I portray it as being aware that one is aware. We are aware of light, for example, because the eyes relay that information. But a human doesn’t just “detect” light, a more central part of consciousness knows that it detected light. I modeled that “knower” as the core of consciousness, and went on to claim that it is the gradual development of the core knower as one ages that is the basis of subjectivity.
This knowing that you know is what I'm dealing with in another
thread. Actually, for now, I'm just trying to figure out how you can know that you know a statement is true in different kinds of formal systems, but I intend to extend it to knowing about your observations/"conscious experience"/evidence. You may be interested in reading http://jamaica.u.arizona.edu/~chalmers/papers/penrose.html article by Chalmers, especially "2. Penrose's Second Argument".
As you imply, all the humans living in this universe share that universe, and can receive information about it;
I'm not sure what you mean. I assumed information (evidence) could be shared between two WSEs and called the set of that shared evidence the WOE. Adding a third WSE would give you at least a second WOE which may or may not share evidence with the first WOE. Between Alice, Bob, and Cathy, you would get WOEs AB, AC, BC, and ABC, some of which may be empty and so on, I'm sure you get the picture. (BTW I mean "sharing" as "having in common", just a state of affairs, not an action.) For the WOE to be nonempty, some weaker form of your statement would have to be true. If a WOE was equivalent to a WSE, some weaker form would be true. But I wasn't equating evidence with nature or being. The WSE is only part of being human- sharing evidence isn't the same as sharing what I think you would call your "point of consciousness". So instead of "living in this universe" I would say "being evidenced in the WOE" perhaps or "being partially evidenced in the WOE". People would have to infer the nature from the evidence and this may involve induction. Though presumably you can deductively infer your own nature from your own evidence. I'm not sure what that entails, it gets tricky. I would have to consider it further, but I want to finish this post some time today.
Anyway, yes, I do personally suspect that your statement is true.
I can look at a tree, and you can look at tree, and that is one way I can know if what you say corresponds to some actual aspect of reality.
Exactly. And the same process is involved in exchanging abstract ideas. We agree that we cannot draw a perfect circle nor a line of infinite length, right? These things have a "nonphysical" nature. Yet formal languages can describe these things in such a way that different people can know they are talking about
precisely the same things (given some assumptions, of course)
without ever having pointed to the same perfect circle or infinite line in each other's presence. You and I can talk
informally about trees and come to know that we are talking about the same thing (to a certain degree of precision)
without ever having pointed to the same tree in each other's presence. Physicists can talk about photons and know they are talking about
precisely the same thing
without ever having pointed to the same photon in each other's presence. So why can't you develop a formal sign system that describes union in such a way that different people can know they are talking about
precisely the same thing (given some assumptions, of course)
without ever having pointed to the same union in each other's presence. If evidence of perfect circles, infinite lines, trees, and photons is acceptable, why would evidence of union not also be acceptable?
I'm saying that our ability to share evidence of these things depends not on the nature of the things but on our system of communication. All of our systems of communication- whether they internally ackowledge it or not- use signs- they are sign systems. I think what you are doing is the same as what could be accomplished by a formal sign system.
However, because of the apparently non-physical nature expected for a “general” consciousness pool, for this thread a certain subjective experience was relied on for evidence. As evidence I cited reports of people who’ve practice “union.” Their experience is subjective, not “objective” as science demands, but I claimed that such inner experience might provide information that the senses cannot detect, and so when added to a sense data, might allow us to create a better model.
Exactly what a formal sign system could do- be a theory incorporating all evidence- subjective and objective- bringing it all together under the same theory. Kind of like a TOE for evidence. The theory would still be inductive if it spoke to the nature of things, I'm not suggesting otherwise- well, not yet. There is possibly an interesting "out" if a person's reasoning could be modeled by a formal sign system. A formal sign system could potentially
be you in an indirect, incomplete way- it would actually just represent all of your knowledge and such so it wouldn't actually be you- but "be you" sounds more impressive. I haven't much more than an inkling of how this would work. But the system would include your knowledge about yourself- and if you knew that you were conscious, you could possibly know that other people are conscious by virtue of your shared evidence which the system would fully and precisely describe. If you could demonstrate your own consciousness to yourself, the consciousness of others could follow. I mean "know" in the strongest way- and as true justified belief. And I mean "true" in the strongest way. Anyway, that was a bunch of BIG "ifs" and "possiblies". I just get so excited I can't contain myself sometimes.
There's some link I still feel I haven't made quite clear enough yet, but I'll stop here and continue to look for it.
