Your post deserves a detailed response but for sake of all the other things I ought to be doing I'll try to skip through it a bit superficially. We agree on many things but I'll focus on where we disagree.
Your use of capitalization startled me. Just last week I thought of the same idea of capitalization to clear up a confusion which has popped up several times on PF between me and others and which always seems to get dropped without resolution.
Capitalisation is commonly used in the mystical literature for this purpose. As you say, it avoids a lot of confusion.
God=You=Me=Plato=Mind=Buddha=Athman=Brahman=
Can't argue with that.
First, I have always been a little bit uneasy with Nagel's 'what it is like'. It just seems that we could come up with a better characterization of what we mean, but it is also clear that nobody has done so yet. Taking the characterization literally, it says that consciousness is a metaphor. We are saying that We are conscious of A if and only if We know that A is like B
This seems to be a misunderstanding. By 'what it is like' is meant A knowing what A is like, not A knowing what B is like. Of course, when we describe 'what it is like' we must use metaphors and analogies, but in immediate experience knowing what A is like is knowing what A is like, not B or C. So I'd say your definition "the ability to know" is not fundamentally different to "what it is like", since we cannot know what it is like without being able to know.
You have a much better grasp of Rosenberg than I do so I won't comment on that part of your post. I find his theory too complex to grasp. I agree with equating individuating sentient beings to natural individuals, but either I disagree with his ideas about effective and receptive properties or I haven't understood them, or both.
As I see it, the mysterious "communication link" i keep talking about between Mind and brain is exactly what Rosenberg calls a "carrier".
Makes sense. But is there a need to to posit a carrier if Mind and mind and brain are ultimately all the same thing?
With the possible exception of the word 'duality', I think We now do agree on the key definitions and I think We agree on most of the rest.
I agree. But the issue of dualism is for me so fundamental that until we resolve that one I feel our agreement will be a bit superficial. Perhaps one of us could start a thread on dualism/nondualism.
And I think the only way to remove the sloppiness is to revert to mathematics and develop these ideas as formal systems. You have gotten My hopes up that Spencer-Brown has already got a start on this, but I don't know enough about his work yet to be sure. I would very much like to know more about it.
Yes, I find it very useful to relate all this to formal mathematical systems, and in fact find it quite impossible to separate metaphysics from mathematics. I'd argue that GSB did a lot more than make a start and that he got to the end. But again, perhaps that's one for another thread.
Concerning the definition of 'duality', it is not really important to Me. I don't care whether people call me a dualist or not, and i don't use the term, or any connotations of it, to try to express My ideas. I feel the same way about the term 'God'. Both terms seem to have such very different meanings to different People, that unless they are carefully defined first, I think it is a mistake to use either one. So I try not to.
I've got a feeling we misunderstand each other when it comes to dualism. You say it is not an important issue, yet it is a vital issue for mystical writers, which suggests a significant difference in views.
Concerning Buddhism, because of your suggestions i have now completed two courses covering the subject. I have been fascinated by what I learned. The net of it is that I can interpret Buddhist doctrines, or sutras, to be completely in accord with My own cosmological views.
Was the lower case 'i' deliberate?

It seems to me also that your view is nearly consistent with Buddhist doctrine. However, the concept of nonduality is so central in Buddhist cosmology that it cannot be skated over. This is something we might discuss at length sometime.
On the other hand, I can identify what you might call "sloppiness" or "confusion" in each one. I learned that these same problems were identified by later Buddhist thinkers who founded new schools that fixed the problems. To my surprise, as I learned about these "fixes", I found Myself in agreement that they were an improvement on the previous notions.
I'm not sure how you would have reached this view. Can you give examples? It's very hard to find instances of sloppiness or confusion in the sutras, and I've never heard any Budhhist suggest that there are any.
But, with one exception, I think we can come to understand and explain everything that exists. That one exception is the problem of the ultimate origin of the ultimate ontological entity. That one, I think we have to leave open.
I'm not so sure about that, but maybe.
Buddhists themselves don't have a single view on these things, so We can't assume that They have the "correct" view.
The appearance of different views is usually superficial. Do you have examples of different views on anything important.
I think We should feel as empowered as Anyone to think these things through trying to make sense of them. After all We are Brahman.
Quite agree. It's the only way to make sense of them.
If We attribute all free will to the One consciousness, and recognize that the One acts out that free will through us, then everything makes sense.
I sort of agree. However, as far as I can tell, in Buddhism and Taoism what is fundamental does not act at all.
You mentioned quite some time ago in our conversations that we might disagree on the issue of freedom. Here, I can see that we do. If what you said here is a precept of Buddhism, then i would have to say that they are wrong. In My view, the personal 'freedom' so valued in materialist societies, if exercised by Mind, is the most precious and important feature in all of reality.
OK, but you are assuming that this freedom is exercised by Mind. I'm suggesting that it's exercised by mind.
"If one thinks that his infinite Spirit does the finite work which nature does, he is a man of clouded vision and he does not see the truth."
Bhagavad Gita
Chap. 18
I think it is clear from human history, that to the extent that humans think for themselves, their condition greatly improves.
Hmm. I don't find this to be at all clear. But perhaps I'm reading the wrong meaning into the sentence.
In my view, all the discussions surrounding the notion of duality are nothing but sophism.
Great. At last we have something we can really disagree about.
I don't think anything can be learned or gained by precisely defining 'dualism' and then taking stands on implications of that definition. That is not to say that there aren't logical problems (which I think you might call metaphysical) with any proposal for cosmic origins. In fact, as i have consistently said, I maintain that each and every proposed explanation for the origin of reality, whether it is string theory, religious creationism, some mythical epic account, or any other philosophical, religious, fictional, mythical, whimsical, logical, or psychological account, will have exactly the same problem: whether reality had a beginning or not, and if so, how did it get started, and if not how can we explain its existence.
This is just the point. These problems do not arise is nondual cosmologies. Lao-Tsu, the Buddha, Spencer Brown et al, they all claim to know the truth about our origins. Indeed, knowing this is necessary as a basis for knowing anything much, according to the mystics, for to know what one is one has to know how one originates. As Lao-Tsu says, knowing the ancient beginnings is the essence of Tao.
As you said, the concept of duality plays no part in My view of reality and I don't think it ever will.
Wanna bet? You won't be able to explore Buddhism and yet avoid this issue, It is the key to everything. Buddhism is sometimes called the 'Middle Way' view. The reason for this cannot be understood without an understanding of duality and nonduality.
For example, to understand Buddhist docrine it is necessary to understand the nonduality of Samsara and Nirvana, the unity of appearances and reality. And only by understanding nonduality is it possible to see how metaphysical questions like "Did the universe have a beginning or not?" can be resolved. Crucially, the central mystical experience is one of nonduality, and it is the principle or fact of nonduality that lies at the heart of the mystical doctrine.
"If we ask definitely ‘What is Brahman?’ the answer in modern terms would be: ‘Brahman cannot be defined because it is Infinite. It is beyond thought and beyond imagination. It is nothing in the mind and nothing outside the mind, nothing past, present or future. These are only conceptions in time and space. But the nearest conception of Brahman we can have is to say that it is a state of consciousness beyond time when SAT, CIT and, ANANDA, Being and Consciousness and Joy are ONE.’ We thus have the Mandukya Upanishad that explains the paradox that Brahman is all, and Brahman is nothing, or no-thing."
Translators Introduction (xl)
The Bhagavad Gita
(Trans. Juan Macaró, Penguin, 2003 (xviii))
"When we encounter the Void, we feel that it is primordial emptiness of cosmic proportions and relevance. We become pure consciousness aware of this absolute nothingness; however, at the same time, we have a strange paradoxical sense of its essential fullness. This cosmic vacuum is also a plenum, since nothing seems to be missing in it. While it does not contain in a concrete manifest form, it seems to comprise all of existence in a potential form. In this paradoxical way, we can transcend the usual dichotomy between emptiness and form, or existence and non-existence. However, the possibility of such a resolution cannot be adequately conveyed in words; it has to be experienced to be understood."
Stanislav Grof
The Cosmic Game
I'd just add that it is my understanding that although this resolution, the nonduality of existence and non-existence, something and nothing and so forth, cannot be adequately conveyed in words it can nevertheless be discussed in terms of the principles involved. But only by getting to grips with dualism and the extent to which it infects our thinking. It seems correct to say that in GSB's mathematical model of the universe it is specifically dualism, the making of false distinctions or 'indications', that is responsible for our existence as human beings.
Thank you for the enjoyable discussion.
