Title: Is metarepresentation an effect of self-organization?

Is metarepresentation an effect of
self-organization?
Wolfgang Wildgen
  • Meta-representation and (self-) consciousness
  • Emergence of higher levels of self-organizationin
    biological and semiotic systems

Introduction Reflexion on the concept of
metarepresentation
  • Some being, which is the container of the
    representation, e.g., a human mind, which
    perceives and thinks. We call it the
    repraesentans.
  • Some entity being represented which is not
    directly accessible (absent). We call it the the
    repraesentandum. In many cases it is considered
    as in the focus of the attention of (a), or it is
    the goal of the intention of (a) (in the
    vectorial sense defined by Brentano).
  • Some entity accessible to (a) which organizes the
    link between (a) and (b) and provides a specific
    organization for the system of such
    representations. Peirce calls it the
    repraesentamen.

This discussion gives us rather two bad choices
  1. A concept of representation to which we may add
    (theoretically) an unlimited number of arguments
    (beyond the classical three ones found already in
    Augustine) and which is not only static but
    becomes a kind of unspecific basket of components
    without a clear profile.
  2. A very rudimentary notion which refers to
    processes in the brain (as a proper part of a
    biological entity). As the details we know about
    the dynamics of the brain stem from studies in
    animals, this concept does not properly sepa-rate
    human from nonhuman representations.

The prefix meta
  • The prefix meta (from the Greek adverb µeta)
    means inside of, after and the Latin noun meta
    means center, point of revolution.
  • Meta in Latin has a rather clear meaning as the
    turning point in a circus (for races). If
    representation is a goal-directed process, then
    the turning point after which the race comes back
    to the start/goal could mark the process of
    metarepresentation.

In a circular motion the path may return to a
point identical with the start or deviate from
it. If the deviations are damped, the path is
stable if differences grow progressively, the
attractor becomes chaotic.

Vector fields of point reproductions
There is an intermediate case which is shown in
pattern reproduction and its self-organization.
Every cycle abolishes parts of the original
pattern, but there are one (or several)
attractors to which all divergences tend. In the
examples discussed by Stadler and Wildgen (1987),
a text is reproduced in different series of
reproduction. Some elements of the text are
preserved, others change and finally one or
several core texts emerge from the process of
cyclic reproduction. In the case of experimental
visual patterns reproduction, the underlying
mechanism becomes even clearer.

Literature on the topic metarepresentation
  • Linguistic utterances are public representations
    and typical objects of mental metarepresentation.
    Speakers in intending an utterance, and hearers,
    in interpreting an utterance, mentally represent
    it as a bearer of specified content, that is they
    metarepresent it. (Sperber, 2000 121)
  • Dennett (2000) considers a path from outside in
    (ibidem 21). The overt public use of signs is a
    clear indication of their metarepresentational
    nature (every body can perceive them, reflect on
    them, they are a common good like space, light,
    air, etc.). If we follow this line,
    metapresentations first become supra-individual,
    then social and finally elements of a cultural
    context, to which individuals respond (elements
    of his life world).

The phylo- and ontogenetic evolution of
metarepresentation
  • In actual behavior embedded in a situation. Such
    processes belong to microgenesis.
  • In the ontogenetic development, studies have
    revealed that two- to three year old children do
    not yet distinguish between a state of affairs p
    and a belief that p.
  • Autistic children and adults are impaired in
    their evaluation of the states of mind of others
    (often regarding emotions).
  • Schizophrenia is a late-onset breakdown of a
    metarepresentational system

10
Phylogenetic evolution
  • Current results of experimental studies and
    observations in the wild show imitation and
    simple mind-reading as mani-festations of
    metarepresentation are more common in great apes
    (e.g. chimpanzees)) than in monkeys.
  • As the scenarios of the evolution of human
    language diverge vastly (between an origin two
    million years ago with the species Homo or 50,000
    years ago with the first manifestations of cave
    art), the rise of true metarepre-sentation
    could be very recent.
  • In order to avoid such a quasi-exclusion of all
    living beings, I shall take another avenue which
    may be given the etiquette self-organization or
    emergent structure.

11
Models of self-organization, emergence of higher
complexity
In a more general way every natural system can
have such "phases" or states not altered by small
changes in parameters. The phase is a locus of
macroscopic stability. A physical system (any
system) consists of a number of components (e.g.
water in Figure 1, or a mixture of water and salt
in other cases, etc.). These components are
assumed to be independent of each other.

Extension to cognition
  • "Our results may be interpreted as follows The
    fluid posses--ses a variety of different states
    because of its internal mechanisms. But which of
    these states is realized depends on the initial
    conditions, or, to put things in a different way,
    a partially given pattern is completed in a
    unique fashion. But this is at the cognitive
    level precisely what happens in associative
    memory. Part of a set of data is completed in a
    unique fashion. Multistability means that our
    system can internally store many patterns. Their
    restoration from initial states appears
    simultaneously in all volume elements of the
    fluid, i.e. our fluid acts as a parallel
    computer."

14
The emergence of language
  • The major difference between young chimpanzees
    and children is that imitation (and teaching) is
    much more prominent in children. If humans create
    a rich environment for the training of chimpanzee
    gestures, these may come near to the semiotic
    capacity of young children, but this situation is
    artificial and does not belong to the natural
    environment of chimpanzees. The bias for
    imitation, which is more abstract than emulation
    as it is not controlled by an evaluative testing
    of the model, triggers another process called the
    ratchet effect by Boesch and Tomasello (1998
    602), i.e., the inventory of accumulated
    behavioral patterns does not decrease change
    consists of further elaboration and
    sophistication of the accumulated cultural
    goods.

15
Metarepresentation as an emergent feature of
symbolic behavior
  • The order of documentation by paleontological
    data is
  • lithic technology (after 2,3 million years BP)
  • art (geometric engraving on tools at the stage of
    Homo erectus high level iconic art after
    40,000 BP)
  • myth (probably implied by Paleolithic art, i.e.,
    before 40,000 BP)
  • language (only documented by first systems of
    writing in the Neolithic)

16
Metarepresentation and art
There is good evidence that the painter on the
chair is in fact Vermeer himself, but the drawing
he is making has obviously another motif and
structure than the one on which he appears
himself. Thus the act of drawing by Vermeer is
represented and it has a strong analogy to the
painting shown in Figure 5 in the same fashion
the picture in front of the painter is not
identical with the oil-painting by Vermeer, but
it shares the central topic (and thus the object
of the representation). In a stricter sense, this
painting is not a metarepresentation.
17
The person standing behind the door and looking
at the scene looks simultaneously at the king and
the queen. They appear in the mirror and are thus
only represented indirectly (and with side
inversion). The painter, who is Velasquez
himself, looks also at the monarch pausing for a
moment in his work. One may infer that, when he
continues his work in one moment, he will again
look at the scene with the meninas and at his
painting.
18
The case of a mirror
  • In the self-portrait on can assume that a mirror
    was used by the painter such an inference may be
    sustained by the somewhat unnatural position of
    the person, because in a self-portrait in front
    of a mirror, the painter must after each action
    on the painting return to an identical position
    in front of the mirror.
  • The self-portrait can show a part of the mirror.
  • A portrait may show the person looking into a
    mirror and thus both the painter and the painted
    person look into the mirror and the painting
    represents the effect of looking into a mirror
    (with the effect of the mirror (inversion and
    change of perspective).
  • The mirror may show the painter and his model.
    Both may look into the mirror and this can be
    shown in the painting.

19
Salvador Dali has made such a painting called
Stereoscopic Painting (1976). Figure 7 shows this
painting. In fact the action of the mirror could
be repeated whereby the painter and his model
would appear not only twice but three, four, n
times. In the latter case the of mirrors may
constitute a group of deformations (in the sense
of Leyton) re-establishing identity after a
finite number of steps. As in the case of
video-feed back it can also have a chaotic
attractor and destroy the original input and be
slaved by an internal standard (e.g. a
Sierpinki-structure).
20
The painting including the self-reference to
Velasquez is reproduced under deformations
(roughly described by the cubist style of Picasso
in this period). In this case, Picasso is not
represented, i.e. the metarepesentational
character is not overt. Nevertheless Picassos
characteristic style (in this period of his life)
is like a signature of his presence. Is this a
case of metarepresentation?

Many open questions
  • The strategy followed in the last section is a
    very optimistic one, insofar as a basic
    continuity of laws and principles throughout the
    universe (possibly fixed in the period after the
    big bang and not valid for other universes
    existing beyond ours) is assumed. A less radical
    strategy could allow for rather autonomous levels
    of organization which only share some very basic
    laws with other levels and may be described
    independently from earlier stages, from which
    they have emerged. Thus one could postulate that
    with the rise of consciousness (or
    intentionality) (meta) representations became
    rather independent from the surrounding ecology
    and are characterized by their arbitrariness (in
    the sense of Ferdinand de Saussure). Such
    arbitrary systems would not only control our
    perception of the ecology, in which we live, they
    would even change this ecology from a natural to
    an artificial one and thus reverse the Darwinian
    law of fitness.

28
  • Another path could start from the social
    organization of animals and the techniques (e.g.,
    grooming in higher apes) of social control or
    peace. A shift in the social structure triggered
    by symbolic forms, could have allowed higher
    levels of cooperation, larger societies with a
    network of levels and social subdivisions,
    different role patterns and types of
    socialization. The biological potential would
    have been exploited to a degree impossible for
    socially less organized primates. In this view
    meta (meta )representation would be a
    consequence of a social (economic, political)
    evolution rather than an effect of higher
    cognitive capacities. These two routes may be
    called
  • The route of cognitive enrichment and
    self-referentiality.
  • The route of social complexity and higher levels
    of socialization.
