[KM] Right.  The phrase saying “a difference that makes a difference” must be a 
prototypical example of second-order logic in that the difference appearing 
both in the subject and predicate can accept quantification. Most statements 
framed in second-order logic  are not decidable. In order to make them 
decidable or meaningful, some qualifier must definitely be needed. A popular 
example of such a qualifier is a subjective observer. However, the point is 
that the subjective observer is not limited to Alice or Bob in the QBist 
parlance.

Sorry Loet, but I just don't see the need for an observer. I do think the 
difference must be by something to something (perhaps the same thing) but 
Koichiro's formulation implies this.  Again, I warn against unneeded 
complication.

Koichiro: In order to make them decidable or meaningful, some qualifier must 
definitely be needed. A popular example of such a qualifier is a subjective 
observer.

A difference that makes a difference for a qualifier, thus requires 
specification of:

1.  The first difference;

2.  The second difference;

3.  The qualifier (e.g., the observer).

The first difference can be measured using Shannon-type information, since a 
probability distribution can be considered as a set of (first-order) 
differences. Brillouin tried to specify the second difference as a ?H. ?H can 
also be negative (negentropy). But how does one proceed to the measurement?

“A difference that makes a difference” for a qualifier, thus requires 
specification of: 

1.  The first difference; 

2.  The second difference; 

3.  The qualifier (e.g., the observer).

 

The first difference can be measured using Shannon-type information, since a

 Dear all,
I think that Wheeler's it from bit was the great step in physics, it was the 
basis of modern information interpretations 
of QM, due to Zeilinger and Brukner, and Quantum subjective probability 
interpretation of QM, QBism of Fuchs.

From Pedro's post of: Fri Jun 26 14:39:52 CEST 2015

it is nice returning to the main discussion topic . . . 
Am I out of step, did I miss a topic chance? I thought the discussion topic was 
still Four Domains


Re Xueshan's post of: Tue Jun 23 05:10:30 CEST 2015

So far, on the argument of “It from Bit”, we can not prove it is correct, but 
can not prove it is wrong too.
I argue “It from Bit,” if taken literally, is patently wrong in claiming to 
present ANY information. To even raise to the level of presenting some type of 
entropic value it would at least need to be It from BitS (but it is not 
framed so). . . and a close reading of Wheeler's writing shows his mention of 
bits and he never(?) references a naked bit as having informational value. 
Further, he notes the posing of yes–no questions and that this is equivalent 
to a participatory universe. So, who or what is formulating and then asking 
these universal questions, and what is the point or cause of those questions?! 
This is Krassimir's inferred God, from the earlier posting, is it not?

To my eye It from Bit is a step backwards, and further muddies the waters, as 
the author did not clearly frame his true meaning in this too simplistic 
phrasing – leading to misinterpretations, etc.. This is the same muddy 
problem (but now made worse) in the earlier noted bizarre and unsatisfying 
use of the term information in Shannon-Weaver.

The whole matter of referencing the Tao in tandem with It for Bit I find odd. I 
recall from my own studies that The Tao that can be named is not the true 
Tao. So, to take a purely(?) mystical notion and then to try to overlay or 
relate that notion to information . . . just don't see how that would fit. At 
best I would see an encounter with the Tao as an encounter with Kantian like 
noumena.

My thoughts, for what they are worth . . .

Dear Marcus,

Thank you for this simple and absolutely essential intervention. Allowing
ourselves the freedom to use the same term—'information' which is the
defining term for this entire enterprise—for such different relationships
as intrinsic signal properties and extrinsic referential and normative
properties is a recipe for irrelevance.

 Dear Andrei,



 I would ask for clarification on whether you speak of information in
 your examples as something that has innate meaning or something that is
 innately meaningless . . . which has been a core issue in earlier
 exchanges. If this issue of meaning versus meaningless in the use of
 the term information is not resolved (for the group?) it seems hard (to
 me) to have truly meaningful exchanges . . . without having to put a
 meaningful or meaningless qualifier in front of information every
 time it is use.



 Thanks.

Re: [Fis] It-from-Bit and information interpretation of QM

2015-06-26 Thread John Collier
Dear folks,

I believe that information in itself must be interpreted, and is not, therefore 
intrinsically meaningful. The addition requires, I think, semiotics. Without 
that there are mere mechanical relations, and at best codes that translate one 
domain to another without understanding or integration required. I also see no 
reason that Bateson’s difference that makes a difference needs to involve 
meaning at either end. He did not add makes a difference “to something about 
something”. He just talked about making a difference. Best not to 
over-interpret.

I think that to ignore this distinction does a great disservice to information 
theory by glossing over a problem that any information processing system needs 
to deal with if it is to achieve meaning.

John
