[MP] In TGD approach UPsi_i represents the state of entire Universe

one of course cuts the universe to single self and forgets the rest.

[MP]

In TGD each self is observer and each UPsi_i decomposes

into infinitely many selves. Each self behaves like its own

sub-Universe. Therefore existence of many observers does not

affect the argument in no ways. Actually, it took quite

a lot of effort to find the proper form of strong NMP localizing

appropriately and only the concept of self solved the

problem finally.

[MP]

But is also mathematics fiction? We are doing mathematics and regard is

as very real. In TGD the space of quantum histories IS the mathematics:

there is no difference between theory of physics and physics.

Quantum jumps bring in the living mathematician. This

of course is against the dualist view about theories and reality

as separate things.

What is observed is finite but everything is not observed!

Mathematics is much more than the theorems we can prove.

For universes with overcritical mass density there

is relation between size of cosmos and Planck length.

Hubble data seem however to conform that universe is subcritical

and infinite and expanding. What is nice is that global

topology of universe manifests itself in the local

properties of universe (mass density).

[MP]

The need to transform observers to each other seems to be

the special feature of LS theory reflecting the attempt

to geometrize mind, OK?. In TGD there is no need for

mapping selves to each other. In fact the idea of transforming DNA self to

human self would be non-sensical: Human self can containg somehing like

10^17 of DNA selves!

Presumably LS approach assumes kind of hierarchy of

intelligences such that observers with different IQ cannot trasnformed

to each other smoothly, correct?

[MP] I am afraid that the modelling of quantum jump as tournament or

process could lead to problems. I do not believe that this kind of

modelling is consistent with what we know about quantum jump. How to cope

with Bell's inequalities is the problem. Everything else

in quantum mechanics, even quantum entanglmeent

at the level of configuration space, can be regarded as

classical, but not quantum jump.

I understand the need to model the quantum jump when one

believes in dualism: accepting the quantum jump as it is and adding

to the dualism gives tripartism.

No. Quantum measurement is much more general and primitive concept and

[MP] You agree that clocking and gauging require observer. But

observer is self. The idea about self-awareness as

quantum measurement of quantum measurement does not make sense to

me. Reflective level of consciousness could be identified

either the fermionic contribution to conscious experience

or as pure self awareness in contrast to the contribution

of the experiences of subselves of self to experience:

my thoughts are my subselves.

The definition of self could not be more general! It sounds almost

trivial in its generality: self as sub-system behaving effectively as

p-adic sub-universe. Not a single word about brain or biosystems! Self as

subsystem allowing description using pure quantum state.

Why I like Buddhist ideas is not detailed assumptions but similar

generality: the Westner models for brain and consciousness

are extremely culture biased: few centuries ago brain was

clockwork, then it was hydrodynamical system, then it became

computer, some regard it as a hologram,...

[MP] I would not speak about quantum measurements of meausurements.

This makes sense in dualistic framework were quantum measurement

is just dynamical process but not in quantum framework.

I would rather speak of subselves as collections of quantum measurements

such that these collections become units in the experience

of self: many to one is the basic idea of abstraction.

One of the first victories of TGD approach was solution to the other minds

problem, which I understand as problem about why we do not

have direct access to other minds. Actually we have access

to our subselves: we experiences their lifehistories as

our thoughts, mental images, sensory experiences.

We do not have direct accces to the mind of selves at the same

level as us or to subselves of other selves not to mind

of higher level selevs.

In fact, split brain patients are good test for any theory of

consciousness. I have not yet checked thoroughly whether the little

I know about this topic is certainly consistent with the concept

of self.

[MP] I already wondered whether you have hierarchy of LSs such

that bisimulation is possible only for LSs at same level of

somehow?

[MP]

I am not at all sure that brain only generates the idea of spacetime.

I cannot yet exclude the possibility that also my body contributes

to my consciousness and primary sensory experiences occur at

the level of sensory organs. This hypothesis explains elegantly

Libet's experiments showing that subjective experience of skin stimulation

occurs about 1/2 seconds before the neural activity in sensorimotor

cortex. [Also the location of experience at level of brain nuclei could

do this.]

Cognitive processing certainly occurs dominantly in brain but again

TGD suggests that also organs and even skin possess some genuine

intelligence: there are experimental claims about this. Hearthmath

homepage contains something about intelligence of heart.

Also eyes seem to perform cognitive processing as I learned

some months ago (article in Nature or Science?)

For instance, proprioception might be occur in

body. Brain would only cognitively process this

experience. The situations in which patient loses his body

experience could be explained simply as dissociation of

bodily and brainy self to separate parallel selves.

This would mean that we basically directly experience

the 3-space, brain only analyzes this experience.

[MP]

Physical realism boils down to experimental tests. The

Bell inequalities state this kind of test. If the world

is classical in the sense that quantum jump is modellable

by a process, this can be seen experimentally. Aspen

experiments demonstrated that Bell inequalities hold true

and therefore modellability hypothesis is excluded.

[MP] I am not expecting that you believe blindly what I say.

If you want to learn basic maths of TGD it is quite possible.

The locality in configuration space means

only that physical states are described by

*classical* configuration space spinor fields which are

*functionals of 3-surface*.

If I were to second quantize

these fields, physical states would become nonlocal with respect

configuration space. I would construct manyfermion states

with fermions located at different points of configuration

space (3-surfaces), etc..

Since QFT states correspond to states of field theory in fixed spacetime,

the values of configuration space spinor field for given 3-surface

are counterparts of states of quantum field theory.

Qmind files contain more detailed description of this.

[MP]

Well you state your belief very strongly. Explanatory power

and internal consistency of the

theory is the only criterion for our beliefs.

And as I hjave explained many times, observation

UPsi_i-->Psi_f selects very few classically equivalent

spacetime surface from the huge superposition represented

by UPsi_i. But somehow you fail to see this.

TGD of course reproduces EPR effect, delayed choice, etc..

I would not spend an hour with TGD if it would not.

The analysis of these experiments involves in essential

manner the approximation about pre-existing spacetime

but this is not essential. What matters are the

basic rules of quantum mechanics: quantum jump as something

irreducible, Born rule, the basic rules for constructing

many particle states by tensor product construction.

The question is about what *new* effects TGD predicts.

Libet's experiments, which I discussed in earlier posting

and Radin-Bierman experiment are examples of these new effects

and find nice explanation in terms of new time concept.

*

*>
*

*> Sure! I just fail to understand what "zero modes" are... :-(
*

*>
*

[MP] Zero modes are somewhat technical concept, explained

in qm postings. Configuration space has fiber space structure.

Fiber corresponds to the quantum fluctuating degrees of freedom

in which metric is nontrivial. Propagator is actually contravariant

metric, which shows how beautifully everything geometrizes.

One functionally integrates

over them just as in QFT.

In zero modes metric of configuration space is trivial: line element just

vanishes. There are now quantum fluctuations in these degrees of

freedom.

Zero modes characterize size, shape and classical Kahler fields

of spacetime surface. They characterize what we are used to call classical

physics. Quantum jump indeed involves localization in zero modes

so that every final state of quantum jump is classical in well defined

sense.

Zero modes are purely TGD:eish feature and derive from the

fact that particles are not more point like. They are absent

in QFT. In string models they emerge as so called moduli characterizing

the conformal equivalence classes of metrics for string world

sheets.

Zero modes make it possible to unify classical physics with

the physics of quantum field theories. Fiber<--> quantum field theories.

Base (zero modes)<-->classical physics.

Particle physics is application of quantum theory and in particle

[MP] Certainly it does not do this. It only determines

Quantum jump involving quantum measurement of density matrix

*

*

[MP] Communication at microscopic, CP_2 time level reduces to

informational time development. Selves generate no p-adic entanglement

during time evolution U lasting for infinite time (nothing to do with

psychological time). Only final state is unentangled and only p-adically.

This allows information flows between selves and formation

of cognitive representations about other selves.

One can calculate information currents etc.. and assign

information gains of various types to various selves.

This is fundamental but not very practical level.

At the level of classical spacetime surface the communication

can be seen as a formation of geometric cognitive representations.

Cognitive spacetime sheets interact with physical ones and

their behaviour reflects the behaviour of material spacetime

sheets. Wormholes mediate classical gauge fields

between spacetime sheets.

At the macroscopic level of selves communication can be simply

seen as sensory experiencing. Good working hypothesis is

that various sensory experiences are determined by location

in zero modes characterizing classical world and that

various macroscopic quantum phases quantum correlating

with qualia are determined by the location more or less

uniquely.

[MP] It is so economical to speak just one quantum computation

decomposing into sub quantum computations (selves).

[MP] We are working with quantum computer.

In quantum computation the entire quantum computation becomes

purely physical process, something analogous done by the reading

head of the Turing machine.

Quantum computation described by U last infinite

time: it does not make sense to speak about halting in finite

time(;-). To speak seriously, quantum computation halts by its very

nature. There is no line in program code telling when to halt. U is just

part of quantum jump which occurs including the halting.

My basic objection against computational

approach is that you try to apply it to basic physics.

I regard classical computation as something emerging at very

high level when selves begin to model the world and

build simulations of physics. At this level it makes sense

to speak about halting probabilities.

[MP] Fact is that GCI implies basic predictions of GRT and entire

structure of gravitational theory including even basic dynamical

principle. Without GCI one must start from scratch.

Conscious beings certainly give names to things but this is

different activity having nothing to do with Riemann geometry.

[MP] The problem is that mathematical description of change becomes

of TGD is the solution to this paradox of GRT.

[MP] I do not require you to agree with my view about reality!

I want just to compare. For rather selfish purposes(;-)! I want

to relate my approach to computationalist approach and see

what parts of it come from quantum approach. It is fine

if my counter arguments help to develop the dualistic approach.

For instance, the notion of self solved not less than six

objections.

a) How the notion of psychological time and its arrow emerge

from the theory: earlier approach was almost correct but

localization in zero modes and drift of cognitive spacetime

sheets were still missing from this picture.

b) How one can understand memories about previous conscious

experience as *genuine* memories rather than only simulated

re-epxeriences.

c) How can one understand the passive aspects of conscious experience

(sensory experience,etx..) if single quantum jump seemingly

involving selection determines the contents of conscious experience?

d) How can one achieve objectivity of sensory expeirences, if

each quantum jump replaces universe with a new one: the progress

resulted from the observation that weaker concept of objectivity

defined as quantum statistical concept is probably enough.

e) How can one understand binding: the earlier model

for binding was actually for sensory experience*r*s,

not experiences! Summation hypothesis for sensory experiences

leads to the hierarchy of selves.

f) Is there any hope of understanding how universe can understand

itself and construct a theory about itself. Hierarchy of selves

and infinitely long subjective memories gives good hopes of this.
