Introduction: Shannon vs Austen

Many scientists and engineers, including, surprisingly, some psychologists and
neuroscientists, seem to think that what the word “information” and its
equivalents in other languages refer to is what Claude Shannon’s ground-breaking
1948 paper referred to as “information”: a measurable property of signals that
can be stored, transmitted, compared, compressed, decompressed, corrupted,
repaired, encrypted, decrypted, etc. (Shannon, 1948).

Many of Shannon’s admirers seem to have forgotten that there is a much older,
widely used, theoretically important notion of “information”, which was familiar
to Jane Austen and used in her novels, and also occurs in non-technical,
conversational, uses of the word “information”. This concept of information is
essential for our understanding of biological evolution and its products
(including humans) and for attempts to understand what natural intelligence is
and how it works, including attempts to model and replicate natural intelligence
in machines.

Shannon himself did not make this mistake of conflating the old concept of
semantic information with what he called “information”. Margaret Boden
comments on this in her two volume survey of cognitive science and its history
(2006):


This term was drawn from Shannon’s information theory, developed at Bell Labs to
measure the reliability or degradation of messages passing down telephone lines
(Shannon 1948; Shannon and Weaver 1949). But the “messages” were thought of not
as meaningful contents, conveying intelligible information such as that Mary is
coming home tomorrow. Rather, they were the more or less predictable physical
properties of the sound signal. In Shannon’s words: “Frequently the messages
have meaning; that is, they refer to or are correlated according to some system
with certain physical or conceptual entities. These semantic aspects of
communication are irrelevant to the information problem. The significant aspect
is that the actual message is one selected from the set of possible messages.”


     ………………………

In short, “information” wasn’t a semantic notion, having to
do with meaning or truth. It was a technical term, denoting a statistical
measure of predictability. What was being predicted was the statistics of a
physical signal, not the meaning–if any–being carried by the signal. As a
technical term for something measurable, “information” needed a quantitative
unit. This new unit was the bit (an abbreviation of “binary unit”).

In contrast, Jane Austen frequently used the word “information” to refer to
information content, not properties of the information vehicles
expressing that content.

https://en.wikipedia.org/wiki/Jane_Austen

“English novelist known primarily for her six major novels, which interpret,
critique and comment upon the British landed gentry at the end of the 18th
century.”

Born 1775. Died 1817

I’ll summarise Shannon’s notion and contrast it with Jane Austen’s notion
(illustrated using extracts from her novel Pride and Prejudice
below). She was primarily concerned
with useful information contents of various kinds,
whereas Shannon, as illustrated above, was primarily concerned with mathematical
properties of information vehicles.

I’ll try to explain the differences between their approaches, and contrast both
of them with the views of Auletta et al. below
who, like Shannon, regard information as something transmitted and received,
though they focus more on the sender than the receiver.


The oldest type of information: control information

The work for which Shannon is famous was primarily concerned with information as
something that can be stored, transmitted, or transformed
(e.g. compressed, uncompressed or translated from one notation to another),
whereas the older notion of information is a notion of something that can be
used for other purposes than such “syntactic” operations, and which can
be more or less useful. Moreover its usefulness can depend on other things, such
as the state of some part of the world, or a user’s current intentions or needs.

The uses are many and varied, including recognising a need, a threat, or a
source of something useful, distinguishing known and unknown individuals,
selecting a goal (e.g. to meet a need or deflect a threat), finding a means to a
goal (e.g. selecting an available action, or an available sequence of actions,
or a route through space, to achieve the goal), making predictions, and many
more.

There are also many actions that can be performed on information, e.g. deriving
new information from old, detecting an inconsistency, detecting an ambiguity,
refining information by adding new details, using theoretical information to
explain some other information gained from observation or reasoning, checking
whether one information item is relevant to another (e.g. whether it answers, or
helps to answer, a question), and many more.

The information content of a question is a request for some other information
that will answer the question. The information content of a command or
instruction or suggestion includes specification of some action or type of
action that could be performed.

I suspect none of those statements would have surprised Jane Austen or many
other thinkers before and after her, who had never encountered Shannon
information.

Evolutionary changes produce new physical structures, capabilities, and
behaviours, but they can also extend information-processing abilities, in many
different ways, including extending uses of information during growth and
development.
(E.g. as explained below
in connection with Meta-Configured genomes.)

Being of use is a more fundamental feature of
information than being physically manipulable, since there would not be any
point in storing, manipulating or transmitting information, or even creating
information items to be stored or transmitted, if the information could not be
used.

Having the potential to be used applies to both true and false information and
information contents that are neither true nor false, e.g. questions or
imperatives (commandments?). It is possible to use false information
inadvertently or deliberately, e.g. in political speeches or commercial
advertising.

However, not all control information has the potential to be true or false: e.g.
a road sign or traffic light telling you to stop is typically part of a complex
traffic control system rather than a piece of factual information that can be
true or false.

The most basic use of information, in all forms of life, including the simplest
forms of life, is for control — initiating or modifying an action or
process, or selecting between things to do, selecting when to start or stop
processes, or modulate them, e.g. speeding up, slowing down or changing
direction, and many more.

Moreover it is often sensible to store things that are never used, e.g. plumbing
tools, because situations could arise in which they would need to be used, and
that is also true of information. Information that has the potential to
be used for control (e.g. in deciding what actions to perform) need not
actually be used for control — but that does not prevent it being
potentially useful control information.

Information, in all these cases, is something abstract, potentially but not
intrinsically concerned with relationships between some actual needs or goals,
situations, and decisions or selections.

It involves structures — parts, and wholes, and relationships — but that in
itself does not imply that there is any numerical measure. A single number, or
point on a scale does not capture the required useful properties of information.

There may be measures associated with things that are referred to in items of
information, but those are not measures of information: e.g. one piece of
information could be about a collision between a child and a doorpost, and
another about a collision between an asteroid and a planet. The two events have
many measures, e.g. amounts of physical matter involved, amounts of kinetic
energy transformed into heat energy, but those are not measures of
amounts of information.

Information can be about inaccessible or remote entities. There are old
philosophical problems about how it is possible to refer to, think about, ask
questions about, things that have never been encountered as sensed, or more
generally experienced, objects. My own view, initially proposed in
Sloman(1985) (and later extended by Ian Wright)
is that semantic content beyond what’s immediately accessible can be based on
the need to fill gaps in causal loops: e.g. if some of the contents of a
machine’s current sensory experience change spontaneously, then something
outside the machine can be postulated as a cause of the change: “loop-closing”
semantic content.

If motions of limbs or rotation of a head seem to cause changes in visual
contents and there is no direct connection between the relevant muscles and
retinal cells, then an animal or machine may use mechanisms for postulating
external causal intermediaries, and for inventing theories about what they are
and how they work, including, for example, differences between visually
perceived changes caused by moving your hand in front of your eyes, and changes
caused by rotating your head so that new parts of the environment come into
view. Of course, that sketch has to be filled in with a great deal of mechanism,
but it is clear that biological evolution combined with features of the
environment has produced extremely sophisticated and varied visual mechanisms
dealing with such “loop-closing” semantics.

Biological evolution evidently
discovered the importance of loop closing semantics in biological mechanisms
used for control on the basis of information outside the organism, or in the
organism but outside the control mechanism.

These biological mechanisms can be thought of as precursors of the more
sophisticated cases proposed by 20th Century philosophers of science (e.g.
Hempel, Pap, Tarski, and many others) who developed anti-empiricist explanations
of how scientific theories can meaningfully refer to entities that scientists
cannot experience, with properties that cannot be directly measured, e.g. the
mass and charge of an electron, or the temperature at the surface of a star
light-years away from us at a long-past time.


More on Shannon’s notion of information

I’ll present a very crude summary of Shannon’s ideas, in order to explain how
his notion of information differs from the much older notion, which is much more
familiar to most people, including people who lived long before Shannon, such as
the novelist Jane Austen, whose ideas about information are summarised below.

In Shannon’s sense of the word “information”, there is a numerical
quantity of information associated with a
signal, derived from the size of the class of alternative signals possible in
that context. In that sense “The caterpillar chewed the leaf” and “The asteroid
destroyed the island” might have comparable “amounts” of information as English
sentences of the form “The [noun] [verb] the [noun]”, since both select from the
same word classes, ignoring the structure at the level of the alphabet used.

If each signal in a set of possible signals is constructed by concatenating
symbols selected from a fixed set of symbols, then the Shannon information
content depends on the size of the set of symbols and the number of symbols in
the signal. For example if only two signal elements are used, a dot (“.”) and a
dash (“-“), as in Morse code, then any signal made of four components, e.g.
“….”, “—-“, “-.-.”, etc. has an amount of information expressible in terms
of the number of possible four component signals using only two types of
components, namely: 16. Each such four component signal eliminates 15 of the 16
possibilities.

Likewise a five component signal using a two character alphabet
eliminates 31 of the 32 possibilities. So it has more Shannon information than a
four component signal. (There are different mathematically equivalent ways of
defining a measure of information based on this idea, some more generally useful
than others.)

If instead of only a choice between two items for each signal component, the
code used allows four choices for each component, e.g. one of these: “-“, “.”,
“=”, “+”, then instead of the information measure being based on 2x2x2x2 = 16,
it will be based on 4x4x4x4 = 256. So the measure of how much is excluded
increases as the number of options for each item in the string increases and
also as the length of the string increases.

For technical reasons, Shannon’s measure did not directly use these numbers, 16
and 256, or the numbers of items excluded by each signal, e.g. 15 or 255. but
numbers derived from them. The main point is that a signal that excludes 255 of
256 possibilities can be said to have more information, in Shannon’s sense than
a signal that excludes 15 of 16 possibilities, a smaller ratio. So two equally
nonsensical words for an English user, e.g. “zzxxjalp” and “azbycxxyrk”, which
convey no information if sent unexplained as a message, will have different
amounts of Shannon information. Assuming the same alphabet is in use, the second
is longer and excludes a higher proportion of alternatives than the short word,
and therefore has more Shannon information.

This is analogous to the way in which saying that an animal in the distance is a
bird gives less information than saying it is a crow, because “crow” excludes
more possibilities, and therefore supports more inferences, than “bird” does.
E.g., you can therefore make more inferences from “Tweety is a crow” than from
“Tweety is a bird”. Intuitively the former therefore has more information. That
shows a loose connection between our ordinary concept of information and Shannon
information.

Each of the two words “bird” and “crow” contains four letters from the same set
of 26 possible letters and therefore, considered purely as signals, they have
the same amount of Shannon information. Considered as words of English, however,
they each have a smaller information measure than that, because not all
combinations of four letters of the alphabet are words of English, e.g. “iiii”,
“zyww” are not, which most English speakers will (somehow!) know without being
told, so the words “crow” and “bird” exclude a smaller number of alternatives
than they would exclude if all four letter sequences were words of English.

A further complication is that there are some four letter words, e.g. “pick”,
which have (at least) three meanings, all of which are excluded by use of the
word “crow”, so that increases the number of words excluded. But this has
nothing to do with what the word “crow” means, i.e. what information it can be
used to convey.

There are many technical details omitted by this summary. The main point to note
is that this concept of information measure, expressible as a number,
which turned out to have profoundly important applications in science and
engineering, refers only to the structure of the signal itself and the size of
the set of alternative possibilities with that structure. Shannon’s measure of
“information” in this sense has nothing to do with what we would normally refer
to as “meaning”, “content” or what is “denoted”, or “referred to”.

It is a syntactic measure that is not directly connected with
semantic content, though it may be indirectly connected when applied to
signals in a known language. Shannon understood all this, as is shown clearly by
a video presentation in which he discusses maze-learning by a mechanical mouse
he had built, clearly indicating that that the mouse acquires information that
later can be used by getting from anywhere in the maze to the goal point. But
his choice of the label “information” in his publications seems to have confused
many highly intelligent people. (He apparently later regretted using the label
“information” for his concept.)

I have found Shannon’s video online in two places:

There are many online documents explaining Shannon’s ideas in more technical
detail and contrasting them with alternative ideas. For a philosopher’s overview
see Floridi’s Stanford Encyclopedia of Philosophy entry.


Another, much older, concept of information: Jane Austen’s

In English the word “information” normally has a quite different meaning: it
does not refer to a numerical measure of the structure of a signal, or how a
particular signal relates to the set of possible signals. Rather “information”
(like related words in other languages) refers to the subject matter
conveyed to a listener or reader who understands the signal. Moreover, as we’ll
see later not all information is associated with signals sent from a transmitter
to a receiver, insofar as perception, reasoning, remembering, planning,
deciding, acting, surmising, suspecting, asking, and many more, all involve use
of information.

Sometimes the subject matter, or information, identifies an entity of some sort,
e.g. London, or the tallest building in Paris, or William Shakespeare. Sometimes
it is a fact, or possible fact, e.g. “Humans will be born in spaceships by the
year 2250”, or even something false, e.g. “The Eiffel Tower is in London”, or a
question, or an instruction or command (the answer to “what shall I do?”, which
might be “sit on the mat next to the door and twiddle your thumbs”).

These are all examples of semantic content, expressed here in printed English,
though in principle the same semantic contents could be expressed in spoken
English, hand-written English, or many other languages, using different words,
and different textual forms for those words, or in sign languages whose physical
instantiations are evanescent body movements.

Pictures and diagrams can also have semantic content though the mechanisms (in
brains or computers) required for producing and interpreting them are different
from those used for producing and interpreting words, phrases and sentences.
Perception and understanding of a picture is related to but different from
visual acquisition of information, e.g. about what exists and what’s happening
in some part of the environment. Visual information acquired in ordinary life
typically does not have a sender, and in many environments will have a large
number of independent sources, e.g. different plants, paths, walls, boundaries,
and insects seen at a moment in a garden. There will be no well defined measure
of amount of information in the whole scene though there will typically be many
different kinds of information.

However, if a picture, or video, stored in a computer is represented by a
computer memory structure composed of bits (symbols chosen from a set of two
elements, e.g. ‘0’ and ‘1’) then the number of bits will indicate the
information content as measured by Shannon.

There are ways of compressing the signal size required for transmitting or
storing such picture elements because of the amount of repetition they often
include: e.g. for large regions of an image that are all one colour, or because
of repeated pairings or groupings of information items. So the amount of Shannon
information required for storage may be different from the amount required for
the physical display mechanism that has to show all
parts of the image, not a mathematically derived summary. Again, the semantic
information content that a human looking at the image, e.g. information about a
crow next to its nest, is very different from the Shannon information measure.

That semantic sense is the sense in which Jane Austen used the word
“Information” in her novel Pride and Prejudice, published in 1813, about
135 years before Shannon published his paper, though she was mainly referring to
verbally expressed information.

The claim that she often used such a concept of information is substantiated by
a collection of examples of her use of the word “information” in the novel,
presented in the next section. However, I would not be surprised to learn that
she was perfectly well aware that information can be acquired through sensing or
perceiving other things than written or spoken words, or even by reasoning, and
also aware that information can be used in many forms of action, including, for
example, catching a ball, or locating a lost key.


Extracts from Jane Austen’s Pride and Prejudice


With thanks to Project Gutenburg:

http://www.gutenberg.org/files/1342/1342-h/1342-h.htm

Jane Austen knew a lot about human information processing as these snippets
from Pride and Prejudice (published in 1813 — over 200 years ago) show:

She was a woman of mean understanding, little information, and
uncertain temper.

Catherine and Lydia had information for them of a different sort.

When this information was given, and they had all taken their
seats, Mr. Collins was at leisure to look around him and admire,…

You could not have met with a person more capable of giving you
certain information on that head than myself, for I have been
connected with his family in a particular manner from my infancy.

This information made Elizabeth smile, as she thought of poor
Miss Bingley.

This information, however, startled Mrs. Bennet …

She then read the first sentence aloud, which comprised the information
of their having just resolved to follow their brother to town directly,…

She resolved to give her the information herself, and therefore
charged Mr. Collins, when he returned to Longbourn to dinner, to
drop no hint of what had passed before any of the family.

…and though he begged leave to be positive as to the truth of his information,
he listened to all their impertinence with the most forbearing courtesy.

Mrs. Gardiner about this time reminded Elizabeth of her promise concerning
that gentleman, and required information; and Elizabeth had such to send
as might rather give contentment to her aunt than to herself.

Elizabeth loved absurdities, but she had known Sir William’s too long. He could
tell her nothing new of the wonders of his presentation and knighthood; and his
civilities were worn out, like his information.

I was first made acquainted, by Sir William Lucas’s accidental information,
that Bingley’s attentions to your sister had given rise to a general
expectation of their marriage.

As to his real character, had information been in her power, she had
never felt a wish of inquiring.

… and at last she was referred for the truth of every particular to
Colonel Fitzwilliam himself-from whom she had previously received the
information of his near concern in all his cousin’s affairs,

When he was gone, they were certain at least of receiving constant
information of what was going on,

Mr. Bennet had been to Epsom and Clapham, before his arrival, but without
gaining any satisfactory information….

Elizabeth was at no loss to understand from whence this deference to
her authority proceeded; but it was not in her power to give any
information of so satisfactory a nature as the compliment deserved.

Upon this information, they instantly passed through the hall once more…

She began now to comprehend that he was exactly the man who, in
disposition and talents, would most suit her. His understanding and
temper, though unlike her own, would have answered all her wishes.
It was an union that must have been to the advantage of both; by her
ease and liveliness, his mind might have been softened, his manners
improved; and from his judgement, information, and knowledge of the
world, she must have received benefit of greater importance.

And will you give yourself the trouble of carrying similar assurances
to his creditors in Meryton, of whom I shall subjoin a list according to his
information?

But to live in ignorance on such a point was impossible; or at least
it was impossible not to try for information.

but to her own more extensive information, he was the person to whom
the whole family were indebted

Darcy was delighted with their engagement; his friend had given him the
earliest information of it.

“Did you speak from your own observation,” said she, “when you told him
that my sister loved him, or merely from my information last spring?”

Bingley looked at her so expressively, and shook hands with such warmth,
as left no doubt of his good information.

The joy which Miss Darcy expressed on receiving similar information,
was as sincere as her brother’s in sending it.



Exercises for the reader

What did Jane Austen know about information and the processes in which it can play a role?

What sorts of information-processing machinery can account for the phenomena she was
interested in?

Does information have to have a sender and a receiver in order to exist? Can
information be received, or acquired, without being sent intentionally? (Which
of Jane Austen’s examples might be of that sort? What if she had written
detective stories?)

Do the examples show that she understood the importance of both control information
and factual information? What is the difference?

How can information make something happen?

Do an internet search for “loop-closing semantics” — a theory in which the most
basic form of semantic information is concerned with control (e.g. information
used by a thermostat in determining when to turn a boiler on or off, or
information used by the small fan on a fan-tail windmill to determine how to
rotate the main sails to face the wind, or information used by a Watt
centrifugal controller to determine whether to increase or decrease the flow of
steam from the boiler to the pistons).

Exercise: which varieties of control information can you distinguish in
organisms, at various stages of development, learning, behaviour,
competition, cooperation, reproduction?



Emphasising the sending process, not the receiver


(Added 6 Aug 2018)

Auletta, Ellis and Jaeger (2008)
includes the following suggestion:

“One of the biggest misunderstandings in information theory is to have taken
Shannon’s (1948) theory of communication (in the context of controlled
transmission) as a general theory of information. In such a theory, centred on
signal/noise discrimination, the message is already selected and well defined
from the start, …(selected by the sender)…, and the problem here is only to
faithfully transmit or further process, … … the sequence of bits that has
been selected (Auletta 2008a).

On the contrary, a true information theory (as was Wiener’s (1948) original aim)
starts with an input as a source of variety and has the selection only at the
end of the information processing or exchanging. In other words, a message here
is only the message selected by the receiver.”

Note that this makes the assumption (of which I was once guilty) that
information is only something transmitted and received. That assumption ignores
the fact that all that encoding, transmitting, decoding, etc., would be
pointless if information could not be used. So a deep
theory of information should start with users
of information and its uses, which may differ for
different kinds of information and different users.

For example there are many important uses of information (understood by
novelists) that have nothing to do with senders and receivers, since the
information is the content of an intention, a percept, a plan for action, or an
internal self-directed question (e.g. “What made that noise?” “Where did I
previously find fruit?” “Why did my action that previously succeeded fail this
time?”). Although my examples are expressed in English, I suspect that
pre-verbal human toddlers and other animals are able to use much older
internal languages that evolved not for purposes of communication but
for intelligent (self-)control, including perception, deliberation,
control of action, reflection on successes and failures, and many more.
So in addition to discussing information in relation to senders and receivers,
we also need to discuss its relevance to information users.

Then sources, senders, receivers, encoders, decoders, etc. could be discussed as
secondary topics, though for Shannon’s job the secondary topics were the only,
or the main, matters of concern: because his employer was the Bell Telephone
Company.

In the context of the Meta-Morphogenesis project a major way in which
information of various kinds, with various sources, plays central, highly
context-sensitive roles, is in individual development, as discussed
briefly below (Meta-Configured Genomes).

Is that what Auletta et al. intended to say?



Uses of information in other, especially simpler, organisms



(Added Aug 2018)

I expect nobody knows how Jane Austen might have responded (after hearing an
extended report on biological research done long after her death) to a question
like:


“Can other animals make use of information, e.g. horses, cats, birds, snails,
butterflies, earthworms, or even flowers, trees, fungi in a forest and
micro-organisms performing essential functions in human bodies?”

I have a fantasy that one day an Austen scholar, with much deeper acquaintance
with her writings, will compose an imaginary dialogue between Jane Austen and a
biologist discussing capabilities of a wide range of organisms, perhaps starting
with these presentations by Maddie Moate and colleagues:

https://www.youtube.com/watch?v=L7FGxcNPMCE

    
Amazing Animal Architects

https://www.youtube.com/watch?v=spMkaJp975s

    
Monkeys react to magic

and perhaps going on to much simpler, smaller organisms, or even individual
cells in the bodies of living things.

Investigating the varieties of information processing between the very simplest
organisms, or proto-organisms, and the most complex, and how and why the
relevant types of use of information emerged, is the main goal of the
Turing-inspired Meta-Morphogenesis project:

http://www.cs.bham.ac.uk/research/projects/cogaff/misc/meta-morphogenesis.html

That project includes the hypothesis that the most basic and most pervasive use
of information in living things is for control:
receiving, transmitting, storing, retrieving, encoding and decoding are all of
secondary importance, insofar as they all contribute directly or indirectly,
immediately or with some delay, to the use of information, although some
processes whose function is to make information available for use may turn out
to have been redundant because the information is never used. But that doesn’t
stop it being potentially usable information.

Most philosophers who write about information tend to focus on intentional uses
or transmissions of information by humans, whose use of information is typically
complex and varied, with many subtleties. For much simpler forms of life the
uses of information and the types of information are much more restricted though
the physical mechanisms may be quite complex, as suggested by the “chemoton”
theory of Ganti(2003).



The Meta-Morphogenesis (M-M) project

(using Meta-Configured genomes)

This collection of notes on information is part of the background to the
Turing-Inspired Meta-Morphogenesis project, whose aim is to understand the
variety of roles of information in all forms of life, including the information
processing mechanisms used at various stages of biological evolution, and in
various evolutionary lineages, including microbes, plants, precursors of
animals, all varieties of animals, and in some cases uses by larger groups,
including flocks, shoals, symbiotic collaborators, and uses (including mis-uses)
of information by large “virtual” entities, such as cultures, engineering teams,
political movements, and academic disciplines.

http://www.cs.bham.ac.uk/research/projects/cogaff/misc/meta-morphogenesis.html


Meta-Configured Genomes

A key idea that has been under development for some time, in collaboration with
Jackie Chappell, which turned out to be of great
importance to The M-M project, concerns the
multi-stage, multi-level, contexts in which information from a genome (i.e.
genetic information) can be used during development, leading to wildly different
effects of a particular part of the genome in different developmental
environments.

Our ideas constitute steps toward a theory of “A meta-configured genome”,
according to which genetic information interacts during its expression both with
current aspects of the environment and with products of earlier stages of
gene-expression, as illustrated most obviously in connection with the
multi-stage processes in language development. This idea (still under
development) is outlined in: “The Meta-Configured Genomes” (work in progress).

I believe this is closely related to Annette Karmiloff-Smith’s theory of
“representational redescription” during individual development:

Frege on Sense & Reference [Sinn/Bedeutung]


(Added: Aug 2014)

Gottlob Frege made use of a distinction between two aspects of meaning, or
information content, usually translated using the words “sense” and “reference”,
echoing what earlier philosophers had referred to by distinguishing
“connotation” and “denotation”, or “intension” and “extension”. The distinction
is so pervasive that it has probably been re-invented or re-discovered many
times, though using different terminology.

As far as I know this distinction was not discussed by Shannon, although his
1948 paper implicitly makes use of the distinction insofar as he uses the word
“sense” several times, e.g. in contexts like

    
“…if
P is sufficiently large, in the sense of having an entropy power approaching P +
N”


and

    
…the evaluation is “reasonable” in the sense that…“.

However, problems arise when attempts are made to apply sense/reference
distinction to every possible word or phrase or sign or process that in some
sense can be said to convey information or have a meaning.

Examples that cause problems (some of them discussed by Frege) include
demonstrative/indexical expressions, e.g. “here”, “now”, “you”, “I”, “we”, words
that combine sentence fragments to form new larger fragments or whole sentences,
or qualify assertions, such as “but” “although” “perhaps”, “of course”, proper
names, and many others.

A good novelist with a rich and deep command of her language will use all these
hard to analyse words and phrases without worrying about philosophers’
questions. However, a complete theory of information, covering all the varieties
of information contents of portions of human languages, will have to make
explicit the roles of the more complex and subtle words and phrases, as
philosophers and linguists have attempted to do. (A survey is beyond the scope
of this paper. Is there a good tutorial reference?)

I have tried to do this with a little word that causes big problems,
namely “self”, whose linguistic function is sometimes misconstrued as referring
to a special mysterious entity (“the self”) by philosophers and others, here:

http://www.cs.bham.ac.uk/research/projects/cogaff/misc/the-self.html

    “THE SELF” — A BOGUS CONCEPT

Without a good theory covering all the obvious and unobvious cases we are
unlikely to be able to design robots that have minds like ours.

Bateson on “difference”: discussion note by A.S.

(Added here 29 Aug 2018)

What did Gregory Bateson mean when he wrote:
“information” is “a difference that makes a difference”?

http://www.cs.bham.ac.uk/research/projects/cogaff/misc/information-difference.html

Bateson is frequently quoted approvingly by unthinking admirers who seem to
ignore the fact that no matter how memorable the slogan sounds it is not at all
clear what it could possibly mean. Guided by some of Bateson’s writings, the
“difference” discussion note explains that Bateson was referring to some of the
patterns of causal influence produced in brains by information. (With thanks to
Olivier Marteaux for correcting my initial interpretation.)


Margaret Boden’s account

Margaret Boden’s “Magnum Opus” includes much that is relevant.

Mind As Machine: A history of Cognitive Science (Vols 1–2) (2006)

http://www.cs.bham.ac.uk/research/projects/cogaff/misc/boden-mindasmachine.html

The discussion starting in section 15iii (Mathematical Biology Begins),
continuing to the end of 15iv (15.iv. Turing’s Biological Turn) is specially
relevant to the M-M project, summarising work by D’Arcy Thompson, Alan Turing
and others. Most of the rest of the book is also relevant, some portions more
closely than others. In particular see her discussions of the role of the
notions of “information” (as opposed to matter, energy, force, etc.) both in
explanations of natural phenomena and in design of new machinery.

4.v. Cybernetic Circularity: From Steam-Engines to Societies (p.198)


“…the focus of cybernetics was on the flow of information, as opposed to the
matter or energy involved. Because information is an abstract notion, it could
be applied to many different types of system–even including minds.”


Jackie Chappell’s contribution

Added: 6 Jun 2018

For some time I have been collaborating with Jackie Chappell, a biologist who
works on animal cognition, using the concept of (Semantic — non-Shannon)
information attributed here to Jane Austen. Most of her publications are listed
here:

https://www.researchgate.net/profile/Jackie_Chappell

For a sample of her work closely related to this topic, see:

Jackie Chappell, 2014,
Acting on the world: understanding how agents use information to guide their action,
in
From Animals to Robots and Back: Reflections on Hard Problems in the Study of
Cognition
,
Eds., Wyatt, J.L. and Petters, D.D. and Hogg, D.C.,
Springer, pp 51–64,
978-3-319-06614-1,

http://www.cs.bham.ac.uk/research/projects/cogaff/chappell-action-on-the-world.pdf

Chappell’s paper uses the word “information” 27 times in 10 pages — in the
sense of Jane Austen, but mainly in the context of non-human intelligence.

Pre-publication summary:

Most animals navigate a dynamic and shifting sea of information provided by
their environment, their food or prey and other animals. How do they work out
which pieces of information are the most important or of most interest to them,
and gather information on those parts to guide their action later? In this
essay, I briefly outline what we already know about how animals use information
flexibly and efficiently. I then discuss a few of the unsolved problems relating
to how animals collect information by directing their attention or exploration
selectively, before suggesting some approaches which might be useful in
unravelling these problems.

Samuel Johnson on information

Added: 27 Dec 2013

The semantic concept of information is, of course, much older than Jane Austen.
Among many others, Samuel Johnson (1709–1784) used the “semantic” concept
of information:

    
“We know a subject ourselves, or we know where we can find information on it”

quoted in Boswell’s Life of Johnson, 1791.


Dennett Interview Nov 2017

(Added 2 Jan 2021)

I recently came across this interview in which Daniel Dennett reflects on
information:

https://www.edge.org/conversation/daniel_c_dennett-a-difference-that-makes-a-difference

Here’s a sample extract:


“….I’ve been trying to articulate, with the help of Harvard
evolutionary biologist David Haig, just what meaning is, what content is, and
ultimately, in terms of biological information and physical information, the
information presented in A Mathematical Theory of Communication by Shannon and
Weaver. There’s a chapter in my latest book called “What is Information?” I
stand by it, but it’s under revision. I’m already moving beyond it and realizing
there’s a better way of tackling some of these issues.

The key insight, which I’ve known for years, is that we have to get away from
the idea of there being the pure ultimate fixed proposition that captures the
information in any informational state. This goal of capturing the proposition,
this attempt at idealization that philosophers have poured their hearts and
souls into for a hundred years is just wrong. Don’t even try. I’m now coming
around to wonder why it had such a hold on us. It’s quite obvious once you start
thinking this way.”

Note:

I was surprised by the comment about “why it had such a hold on us”. To whom
does “us” refer? I’ve never thought for a moment that Shannon’s theory was about
what we normally understand by “meaning” or “information content”. I remember
arguing against this with fellow students, including at least one music student,
around 1959. My 1962 DPhil thesis was about relationships between meaning
(information content) and truth, and never mentions Shannon, or anything
remotely like Shannon information, although I had encountered his ideas and
decided they were irrelevant to my attempts to understand relationships
between meaning and truth, especially necessary truth. I am surprised that
Dennett did not notice that Shannon had simply misused the normal concept of
“information”. Although many scientists and engineers found Shannon’s ideas very
useful I would expect philosophers, linguistics, and many others to notice its
irrelevance to their work.
