...The examination of awareness -- and I am not convinced that I haven't left something important out -- was actually of something that I think is unconscious, or subconscious. So, yes, Skeptigirl I do think that we can be aware of things of which we are not conscious. In fact, I think the lowest level of -- or simple -- awareness is a subconscious process. My favorite example is of driving on the freeway while your mind is otherwise engaged -- you continue to attend to the road and the process necessary to keep you on the road, but you do it automatically. Most of perception fits this mold -- it is done automatically. But for percepts to have any meaning they must be linked in some way to previous memories, both declarative and emotional, probably with some bits of motivation thrown in.
The example of having a word "on the tip of your tongue" might be instructive here. You're aware of aspects of the word, the semantic net around the word, the "context", without being aware of its hub, the word itself. Yet you are aware that you're unaware, of the deficit in your "understanding". It seems to me the flipside of the driving phenomenon, where you're unaware that you're aware. Anyway, maybe a sidetrack; still interesting, though.
So, in my view, the four typical aspects of awareness -- attention, intentionality, perception, and understanding -- are subconscious processes. But they are of the type that can become conscious.
So, roughly: attention (the full context of what I'm doing); intentionality (the part of the context I'm trying to do something with); perception (changes in the environment...); understanding (...related to changes in context)? -- just to break it down into simpler terms (tho' "context", as in
background and reason, isn't simple), which are, hopefully, easier to agree on.
So, what is consciousness? I think, simply speaking, that one part of it is just awareness of awareness. Largely this is an attentional process -- attention to the processes that are carried out subconsciously -- but also including the other components such as understanding within a 'larger theater'. This is where the 40 Hz potentials and the ideas behind the global workspace hypothesis, which probably represents reverberant loops involving parietal (directed attention), frontal (working memory amongst many other things including attentional states), hippocampal (recreations of declarative memory), and limbic systems so that 'we' act as aware of our awareness and can therefore alter behavior -- which is the whole point of consciousness anyway.
I think "awareness of awareness" might be getting at it -- aware of a mobile locus of attention as a context, not as a concept (which would be "self"-consciousness). I'm trying to sort your description out into my pop philosophical approximation of the beast: a mediation between immediate gut feelings, chronic sense input, postponed rational understanding, and remembered experience: the 4 r's -- reflex, recognition, reason, and recall: two processing systems (reflex and reason) for two sorts of information (recognition and recall). Likely not the best division, but towards an understanding of how the pieces work together...
Two of the big issues become -- what exactly is 'feeling', 'emotion', 'motivation'? And does this adequately explain semantic content?
Back to the paramecium (actually, I don't know much about paramecia; let's posit a simple blob of protoplasm that is photophilic: 'likes' light and seeks it out as a source of energy): I also wonder in what sense it is "aware", if at all. There is a difference between light and dark, and it recognizes and responds to it at some level. Is its organic response just the automatic sum and sequence of its physical parts being stimulated by changes in light and each other, or is there an 'affect' there? Is the blob 'feeling': aaaaaaaaa (normal state, in the light), then AAAAAAAA (distressed state, loss of light)? Maybe more:
aaaaa (increasing energy from light); aaaaaa (rest state, adequate energy); AAAAAA (loss of light, loss of energy);
AAAAAA (almost out of energy). Is the 'feeling' coming from the movement associated with the blob's relation to the light: increasing movement with increasing energy; passive movement with adequate energy; active searching movement with decreasing energy; frantic searching with near depletion (sort of "James-Lange" applied to proto-blobs)? What is the difference between the blob's reaction to light and say a glob of phosphorescent chemicals (or even an electron in an atomic orbital)? They absorb light and change in response; however, their 'response' isn't about maximizing their energy level, which it is with our energy-seeking blob. We don't think of inanimate things as feeling; at some level we ascribe it to animate things. At what level does bodily agitation produce an 'affect'? How, and even why -- maybe the problem of consciousness reduces to the problem of feeling which reduces to the difference between inanimate and animate systems -- literally a matter of life and death?
I obviously haven't a frikkin' clue... just uncluttering, tossing junk out for thought, or not.
