 That is not so clear to me as it seems to be to you.  
 
 Suppose that being conscious is something a brain does.  Then a 
 Observer-second would be one second of that brain activity.  When this OS was 
 magically initiated it would already include potentials traveling down axons, 
 etc, the residue of the previous OS and the precursors of later milliseconds 
 in this OS.  But those underlying physical processes are not what we 
 generally think of as conscious.  They are not things we would report if 
 asked what we are thinking.  Nevertheless they may be necessary for the 
 continuity of consciousness, where consciousness here means the inner 
 narrative - the story I tell myself in my head.  In these thought experiments 
 about OMs there seem to be two contrary implicit assumptions: 
 
 (1) that just the content of the inner narrative constitutes consciousness, 
 as in the analogy of cutting up a book and then reconstructing it's order 
 from the content of the segments,
 
 (2) the feeling of continuity remains in a segment 1sec or 0.1sec or 0.01sec 
 even if that is too short a segment to allow reconstruction of the order from 
 the content.

I suppose you could say that there is no feeling of continuity from one 
microsecond to the next in a normally functioning brain either, because it 
takes many microseconds to make a thought. My point is that whatever it takes 
to make a thought and however vague the distinction between one thought and the 
next is, arbitrarily slicing up the physical activity underlying consciousness 
should not make a difference to the sense of continuity, and no explicit 
ordering is necessary. The counting sequence one, two, three may involve 
millions of slices of brain activity or computer emulation activity spread 
throughout space and time, and it may take many of these slices to form a 
moment of consciousness just as it takes many milliseconds of normal brain 
activity to form a moment of consciousness, but the feeling of continuity 
should be preserved.

You have to say that, given a particular theory of consciousness,

I think we're in agreement, Stathis, but I'm trying to focus on a
problem, and what I think is a non-trivial aspect of evolved brain
functionality that would be required to overcome it. Of course, I agree
with you that each aspect of the experience '.falls perfectly into
position in each case by virtue of its content alone' - it's precisely
what I've been arguing. But there's a subtler point here also, I think,
that leads to the problem. Let's take the 'cat sat on the mat': now
'cat' starts at t1 and 'mat' ends at t2. Let's subdivide t1t2 into
occasions o1-o1000, and let teleportation occur between each. Each
occasion o1-o1000 is as informationally closed as OMt1t2 (the
'teleportation' is of course inserted precisely to make this point),
but now it has become implausible to believe that any individual
occasion, say o492, is of sufficient extent to recover any coherent
component whatsoever of the conscious thought 'the cat sat on the mat'.
And yet, we know that we *are* in fact able to routinely recover such
components, corresponding loosely to a 'specious present' of some 1.5
seconds extent.

Now comes the problem: how do we account for our manifest ability to do
this without invoking some form of illicit 'continuity' between
informationally separated occasions of arbitrarily fine granularity? No
individual occasion apparently contains all the necessary information,
and it seems that we almost can't stop ourselves imaginatively invoking
some sort of continuity over multiple occasions, in order that coherent
experiences can somehow be recovered by summing over the sequence.

I think, if true, this would be a real problem in reconciling our
experience with the facts, and I think therefore that it requires a
real solution (actually an aspect of Barbour's time capsule theory
which I'm extrapolating a bit further). Simply, if what I'm arguing is
valid, it must follow that my assumption about individual occasions
'not containing the necessary information' *must be wrong*.
Consequently, sufficient information to recover 'speciously present'
dynamic experiences *must* in fact be *simultaneously* represented by
the brain - be present on one occasion - and that this simultaneous
'dynamic' presentation must be the engine that renders both the
duration and the dynamism of the experience. And, to complete the
(evolutionary) circularity, this would be precisely *why* the brain
would possess this capability - because without it, extended, dynamic
environmental presentations would simply be *unavailable* to the
organism.

Does this make sense?

David

 David,

 Consider these three examples:

 (a) You utter sentence S, the cat sat on the mat. The word on
 starts at time t1 and finishes at time t2.

 (b) At time t1 while uttering S you are intantaneously teleported to a
 distant location.

 (c) You have no actual past but materialise de novo at time t1 as if in (b),
 uttering  ... on the mat.

 We are interested in your phenomenal consciousness between t1 and t2 in
 each case (ignoring the change of scenery due to the teleportation). It is no
 doubt quite complex, involving not only saying the word on but also a sense
 of self, a sense of the whole sentence and your place in it, an idea that 
 this is
 part of an experiment, and so on. There may even be a lag between action and
 awareness, so that you are actually conscious of saying sat in the interval
 t1t2 rather than when you actually said it, and there will probably be at 
 least some
 sense of continuity between sat and on during t1t2.

 The point is, whatever you are thinking during t1t2, you are thinking 
 *something*,
 and you are thinking the same something in (a), (b) and (c). Whatever complex
 brain processes are occurring during t1t2 in (a) are also occurring in (b) 
 and (c), and
 therefore whatever conscious processes are occurring during that interval in 
 (a) will
 also occur in (b) and (c), and you will not lose your place in the sentence 
 or your sense
 of continuity of consciousness. The OM t1t2 is exactly the same in each case, 
 and falls
 perfectly into position in each case by virtue of its content alone.

I don't think that is a necessary or obvious truth. If there

only contain time-stamps indicating the order

can co-exist simultaneously, just as a the frames

The stored experience is not conscious in itself
any more than the stored movie involves any (ilusion of) motion.

 Now comes the problem: how do we account for our manifest ability to do
 this without invoking some form of illicit 'continuity' between

That all depends on what you mean by individual occasion.
In physics that a purely 3d (0 time-dimensional)
doesn't contain enough information to recover
standard dynamics, and instead a kind of specious present
known as instantaneous velocity is used -- i.e.
the snapshot is of an infinitessimal slice, not a 0-width slice.
(Barbour's Machianism keeps the 0-slices and does without
some features of standard dynamics).

 and it seems that we almost can't stop ourselves imaginatively invoking

Hmmm. Well, sequence per se doesn't require continuity.

Yes, I think this could have been better put. I meant that each aspect

independent 'pov'. etc.

'Isolated' might be a better term. As DD puts it 'other times are
special cases of other worlds'.

Precisely, my dear Watson.

 The stored experience is not conscious in itself
 any more than the stored movie involves any (ilusion of) motion.

 In both cases, that comes in with the recovery.

And I'm saying that the recovery *is* a structure that implements a
specific set of relations between the 'time-stamped' data and the
perceptual apparatus - what I've termed the perceiver-percept dyad. The
dyad's function is to render the time-stamped data in the form of
environmentally-embedded dynamic processes centred on a 1-person pov.
If you press me for the detail of 'render' I'm afraid I can only
respond 'in some way', as you do with respect to RITSIAR. My point is
that the dyad is rendered as a simultaneously compresent structure. As
to *why* the structure is experienced as an 'A'-series, I can but refer
you to my previous suggestions, which you may or may not find
persuasive.

 That all depends on what you mean by individual occasion.
 In physics that a purely 3d (0 time-dimensional)
 doesn't contain enough information to recover
 standard dynamics, and instead a kind of specious present
 known as instantaneous velocity is used -- i.e.
 the snapshot is of an infinitessimal slice, not a 0-width slice.
 (Barbour's Machianism keeps the 0-slices and does without
 some features of standard dynamics).

We don't have to define the occasion in this way. Rather, we look at
what information is available for 'dyadic rendering'. My point to
Stathis was that unless the information representing all stages of a
specific dynamic experience is simultaneously compresent in a single
occasion, however delimited, there could be no such experience present
in that occasion.

  and it seems that we almost can't stop ourselves imaginatively invoking
  some sort of continuity over multiple occasions, in order that coherent
  experiences can somehow be recovered by summing over the sequence.

 Hmmm. Well, sequence per se doesn't require continuity.

No, but the temptation is to try to assemble the information from
different OMs or occasions by surreptitiously invoking 'continuity' -
peeking, IOW.

 Soo...what you are saying is that experiences of
 (seemingly) continuous processes are incompatible with
 presentism, the idea that everything must be recovered
 from a 0-width (temporally) slice. Well, maybe,
 but not even physics goes in for presentism in exactly *that* sense.

Am I? I'm saying that the information driving the experience of
(seemingly) continuous processes must be recovered from simultaneously
compresent sources. The reason is that if one assumes the opposite -
that such information is just recovered from individual events 'smeared
over time' - then you keep losing bits of the (psychological) 'specious
present' because, as the information sequence moves forward, the
earlier bits *just aren't available any longer*. So I'm saying that in
the B-series events are indeed sequentially 'laid out', but that this
of itself is insufficient to account for our own species of episodic
dynamic experience. The A-series (i.e. time-as-experienced) seems to
proceed via sequences not of single events, but simultaneously rendered
'dynamic  capsules' generated by (god-knows-what) brain mechanisms that
have specifically evolved towards this end.

involves taking infinite limits in sets that are already ordered (Dedekind cuts

continuous processes in a continuous spacetime.  Though there have been many 
attempts, no one has shown with mathematical rigor how a continuous spacetime 
can emerge as an approximation of a discrete one.  Physicists mostly think it 
is true, but mathematicians think they're hand waving.  The difficulties of 
numerically solving partial differential equations in computers don't give much 
comfort.

  That is not so clear to me as it seems to be to you.
 
  Suppose that being conscious is something a brain does.  Then a 
  Observer-second would be one second of that brain activity.  When this OS 
  was magically initiated it would already include potentials traveling down 
  axons, etc, the residue of the previous OS and the precursors of later 
  milliseconds in this OS.  But those underlying physical processes are not 
  what we generally think of as conscious.  They are not things we would 
  report if asked what we are thinking.  Nevertheless they may be necessary 
  for the continuity of consciousness, where consciousness here means the 
  inner narrative - the story I tell myself in my head.  In these thought 
  experiments about OMs there seem to be two contrary implicit assumptions:
 
  (1) that just the content of the inner narrative constitutes consciousness, 
  as in the analogy of cutting up a book and then reconstructing it's order 
  from the content of the segments,
 
  (2) the feeling of continuity remains in a segment 1sec or 0.1sec or 
  0.01sec even if that is too short a segment to allow reconstruction of the 
  order from the content.

 I suppose you could say that there is no feeling of continuity from one 
 microsecond to the next in a normally functioning brain either, because it 
 takes many microseconds to make a thought. My point is that whatever it takes 
 to make a thought and however vague the distinction between one thought and 
 the next is, arbitrarily slicing up the physical activity underlying 
 consciousness should not make a difference to the sense of continuity,

Should not, assuming physicalism? Should not, assuming
computationalism?

 and no explicit ordering is necessary. The counting sequence one, two, 
 three may involve millions of slices of brain activity or computer emulation 
 activity spread throughout space and time, and it may take many of these 
 slices to form a moment of consciousness just as it takes many milliseconds 
 of normal brain activity to form a moment of consciousness, but the feeling 
 of continuity should be preserved.

Why? Maybe it supervenes on whatever propels one physical state
to evolve into another.

STEP 7:  Something from nothing. (the big bang)

U(.) = (*) from previous STEP.
 = (()()()()()()()()()()...()()()()())

There is some need to deal with this issue because it leads to the
mathematical drive of EC that we inside see as the second law of
thermodynamics.

NOTES:
1) The axiom set is one single huge fluctuation (*) which I have
previously labelled U and depicted as U(.).

2) The overall 'fluctuation' is the same (a fluctuation!) but different in
that it consists of the temporary coherence of a massive collection of
individual (). The overall process could really be labeled U( as what is
happening is one massive fluctuation followed by a return to 'nothing'
where all the () disperse. In terms of physics you could call this a
single massive 'symmetry breaking' event caused by a single massive
coherence.

3) At the initial point (big bang) there is no structure in U(.) other
than the initial coherence (which can vary throughout but overall still
add up to one super-fluctuation).

4) The underlying processes that are the source of each () are, in
essence, deep randomness. Depth unknown. Call the deeper randomness of
which a () is constructed a []. There can be a variable number of [] in a
(). For EC at this stage we don't have to worry about the number of [] in
(). Although it will determine the initial rules of formation.

5) The underlying processes [] can be incoherent, but dispersal of [] from
coherent () will tend to reinforce coherent emergent [] structures back up
into it. Thus the situation can dynamically persist.

6) The reason it happens at all is that a perfect 'nothing', everywhere
and always, requires an infinite amount of energy. Infinities are
impossible, so the something comes from nothing as an 'average' nothing.
'Nothing' can therefore be be viewed as intrinsically unstable. Any
appearance of anything can be regarded as a temporary failure to be
'Nothing'. This sounds nuts but it's consistent with the facts and
logical.

7) The net result is that the dispersal of () partly or fully into [] and
deeper is the natural drive of U(). () Each () can be thought of as a
mathematician. The number of mathematicians in EC is equal to the number
of () that collaborate according to the rules of formation.

At this point and with further thoughtEC predicts what we see as
energy, entropy, black holes, background radiation, gravity and the
origins of some of our laws of nature. But that's way too much info and a
side issue. We are really interested in the entire class of possible EC
treated as structure made of change based on an arbitrarily large source
of randomness pumped by the instability of 'Nothing'.

I think I've blown your brains out enough with this lot.

NEXT
Before rules of formation we have to look at dynamic hierarchies, lossy
and lossless entities and 'symmetry breaking'.
