Les Sleeth said:I suppose I'd say that the history of our experience is what establishes knowing, and is the basis of memory of course.
You have circumscribed a lot of deep ideas in that statement in addition to the more trivial semantic choices of terms. Here's what I think you are saying: Knowledge is the information that is derived from the conscious experience of the present moment and which is accumulated over the course of time in some sort of memory. The conscious act of knowing occurs only in the present moment but it has access to this accumulation of information in addition to the present stimuli reported by the body and brain.
I think most people would agree that that describes what goes on in each human life. but here I think we are talking about what goes on in reality as a whole. The mystery we are exploring is how to explain the evident plurality of this process if it is indeed singular, as we suspect ( and as Schrödinger suspected) that it is. My time-sharing computer and your ocean of consciousness are simply analogies we are using trying to make sense of this mystery.
Les Sleeth said:As far as I can tell, there is nothing but "now." It has always been now, and it will always be now.
Let me explain some of the relationships I was talking about wrt "now", "the stream of conscousness", "the flow of time", and "the physical world". In Brian Greene's "The Fabric of the Cosmos", he describes our 4D space-time continuum as a loaf of bread (by reducing our three spatial dimensions to two and by considering the long axis of the loaf to be our temporal dimension). Our world lines, then, wiggle through the loaf generally in the direction of the long axis. The notion of "here and now" would be a single point on a world line as we (the person traveling that world line) experience that moment. From that person's perspective, the universe at that moment would be a slice through the loaf which intersects the world line at that "now" point.
He points out that SR says that those slices will have different angles through the loaf depending on the speed of the person (i.e. the angle his world line makes with the time axis). Even small differences in the angles make huge differences at great distances from the world line. Furthermore, GR says that the slices are not planar but have bulges and bends. These facts force us to conclude that the entire loaf must exist at all times rather than "now" (a particular rather arbitrary slice) being all there is.
So, how do we reconcile that with your statements that "...there is nothing but "now." It has always been now, and it will always be now."?
Here's my suggestion. Greene's conclusion is that the entire past history of the universe is as real, and exists in the same sense, as the universe at the present moment. Not only that, the future also exists "now" and is real. This raises a couple questions: How much of the past are we talking about and ow much of the future?
My guess is that the past part of the loaf goes all the way back to the Big Bang. (In my view, the BB was the beginning of our physical universe (the 4D one) but not of all of reality (the 11D one, or whatever the dimensionality).) But as for the future, I think the universe is a work in progress and it extends only to some finite extent beyond the time of this writing on 11/23/04. That makes the entire thing finite in extent.
If you imagine the universe as that static, finite, loaf of bread laced with the world lines of all of us who have ever lived, there doesn't seem to be any special point you could call "now". Using your approach and calling the whole thing "now" doesn't help. The question is, What's so special about this particular point here in Seattle now on 11/23/04?
Well, I think it works like this. Since our loaf of bread is static, and the time axis in the loaf looks just like the other spatial axes, it makes the whole universe a static spatial structure. But since we know there is dynamism in reality, in virtue of our certain knowledge that our thoughts change, there must be a dimension of time which accommodates this dynamism and which is separate and distinct from that long axis on the loaf.
Given that cosmic dimension of time, and given the premise that there is exactly and only one consciousness, the possibilities are obvious for the consciousness to "travel" along any and all of those world lines in any sequence, or in either direction, and for any number of repetitions it wanted. By "traveling along a world line" I mean actually experiencing the life of the organism owning that world line. It would be analogous to one of us traveling from Seattle to Atlanta. You could represent the trip by drawing a wiggly line on a map of the US that would correspond to our loaf with its world line. Or you could talk about the moment to moment experience of the actual trip itself, which is the aggregate of all the "now" moments that occurred at each point on the itinerary.
Now, about the unfinished part. If the loaf is a work-in-progress, how is it changed and extended? I think it is done in two ways: First, there are the laws of physics which inexorably determine the evolution of the gross loaf. Second, there are deliberate, conscious, willful actions performed by organisms during these various "now" points on their respective world lines. These actions don't violate the laws of physics since they are done in a manner I described earlier. They are "under the radar" limits set by the uncertainty principle and they appear to be "random" actions.
The actual sequence and pattern (in the cosmic time dimension, of course) of the single consciousness visiting and acting through these many world lines remains a huge mystery we can only guess at. One possibility is, along the Many-Worlds line, that myriad new loafs are duplicated at each point of choice each with a different choice of a "random action".
Another possibility is that the one consciousness drives one body for a while, then hops to another for a while (these "whiles" are all in cosmic time, of course, but they may have corresponding traces as segments along particular world lines.) each time making choices that push the end crust of the loaf ever further on.
If this guess is close to being right, it would seem obvious that our intermittent periods of sleep and wakefulness might mark those segments on our world lines where the one consciousness "hopped in" and drove for a while before hopping back out to drive another organism. Keep in mind that this activity is done in cosmic time and not in the time represented as the long axis of the loaf -- our familiar time dimension. I favor this guess because it would explain sleep. (In my opinion, sleep is the most baffling mystery of biology. All other biological mysteries, such as origins, specieation, development, morphology, etc. have promising theories to explain them. Sleep has none. Not only does anyone have the faintest idea why animals sleep, the fact that they do seems to me to be an extreme counter-example for evolutionary development. Any animal that developed the habit of sleeping, with its dangerous attendant risks and no known reward, would have been selected against and gone extinct long ago. We see that this has not happened..)
That's probably enough elaboration on your point.
Les Sleeth said:We have plenty of time to discuss this,
Yes, I suppose we do. I don't have a lot of time each day to respond but I do intend to live a long time. So if you can bear with my slow response, we will have plenty of time. Thank you in advance for your patience.
Les Sleeth said:... but I disagree that individual consciousness must be illusory.
Yes, so do I. I hope I didn't claim that they must be. I would only say that it is a common illusion for people to think that their consciousness is separate and distinct from yours or mine or the one which we all are.
Les Sleeth said:I am quite certain that both whole and individual consciousness are simultaneously possible if one learns the secret of the experience.
I agree with you even though I have not learned the secret. But in spite of that, I am quite certain, especially now that I know that Schrödinger agreed, that we can logically deduce the singularity of consciousness.
