Let me get your position straight before I share my view of it. You seem to be advocating the position that words, as shared concepts, must necessarily address the same referrents, and therefore the idea that the same word (eg, green) can refer to two different things (eg, this color[/color] as experienced by A and that color[/color] as experienced by B) is nonsense. Therefore, 'green' cannot possibly refer to a subjective experience of this color or that color, but must refer to something else which is shown to be a common, consistent referrent across different people. Correct?
Almost. What I think is nonsense is the idea that you can understand consciousness to the point where you can discover that what A sees as this color[/color] is experienced by B as that color[/color]. Anyone pursuing to understand consciousness from that perspective is wasting his time.
All the same, it's not correct to say we don't understand consciousness at all. We do enough to come to a judgement of whether people are conscious or not. And that judgement, you must agree, is arrived at through observation of the physical world, not through magically peeking into their subjectivity.
So it's not only perfectly possible to understand consciousness from a purely objective standpoint, but we actually do it all the time. What you said above, I take it to mean we can't do what we've been doing quite successfully for quite some time.
I don't have to construct a reasonable facsimile of visual consciousness to try to understand what it is like to experience it, since I already experience it directly.
Sure, but do you really understand how it is you 'see' things? I for one don't.
A man blind from birth can know he is blind in an abstract sense, in virtue of what is communicated to him by other people, but he cannot know precisely what it is that he is lacking that constitutes this blindness. He could probably construct a nice analogy for himself, however, by imagining that a man deaf from birth faces a similar sort of predicament.
So how would a man unconscious from birth knows what he lacks? Can he construct a nice analogy to understand his predicament?
Notice you didn't know you could see until you learned what vision is. And you certainly don't learn what vision is by experiencing vision, you learn it by communicating with other people. Likewise, you can't know if you're conscious until you learn, from other people, what consciousness is. Which means all you know and understand about vision and consciousness is what you learn from other people. Subjective experience plays no role in gathering knowledge, just as knowledge plays no role in gathering facts about the world.
(I'll leave that last sentence unexplained)
I find some of your other claims dubious though.
I'm not preaching here, I'd like to hear different views and learn from them, but I can only take criticism from people with whom I share some common ground. Sleeth, for instance, does not understand my perspective, so even though I acknowledge his skepticism I can't possibly refute it until we learn more about each other.
That's fine, but again, what that implies is not knowing if one's own subjective experience is shared by others. It does not raise any doubt as to the existence or nature of one's subjective experience, taken on its own terms.
The doubts are not regarding the existence of subjective experience, but with claims made about it. You must agree with me that even something as subjective as "subjective experience" must have an objective counterpart, otherwise we would never know it exists for we would not be able to talk about it. The point that is difficult to get across is that when we talk about "subjective experience", we are actually talking about something quite objective. There's nothing subjective to "subjective experience" that can be talked about, the best we can do is discuss its objective aspects.
I can understand why someone would be tricked into thinking that "subjective experience" is not objective. Langauge is very deceptive in that sense, because it allows us to talk about the subjective in a purely objective way. But it's easy to become confused in the process, and I'm sure I'm not immune to confusion myself. All I know is that I'm less confused than I used to be before I understood some things, but I don't know if I'm less confused than you or anyone else.
I think you are confusing linguistic representations of phenomena with the phenomena themselves.
There you go :)
Say for argument's sake that Harry was the first guy to ever experience a peculiar set of feelings, and that Harry decided to call this set of feelings 'enlightenment.' How can others be sure that they are experiencing the same set of feelings that Harry was when they are tempted to describe their experience as 'enlightened'? Well, they can't be sure.
Actually, they can. We do that all the time. All Harry has to do is find physical correlates of 'enlightenment' in his body or his behaviour.
However, I dispute the notion that anyone can have a new experience and come up with a new word for our vocabulary. Experiences are not so neatly categorized; in a sense each experience is new and unique. We can only label experiences because we learn a way to ignore the differences between them. That subjective way of ignoring differences between experiences has an objective counterpart - it's called language.
Perhaps this would make sense, perhaps not: the reason language is important for experience is that without language you can't experience the same thing twice. Moreover, if you can't experience the same "thing" twice, then the only "thing" in your universe that you can possibly experience is a meaningless mess of something we don't have a word for.

What is there left to understand after ignoring subjective experience? Unconscious mental processes. So you are a proponent of a theory of consciousness that describes unconscious mental processes
What's unconscious about a smile?
