‘1. Building artificial living beings/objects as a proof for competing claims about different aspects of life and different levels of the living organization. This is the same motivation of artificial intelligence in regards to cognitive science. It is indeed an innovation in science, since physics relied principally on prediction for proof and validation. In these cases we also have validation by construction,
quite a different matter.’
I have promised that the theory is explicit: the model does as the subject does. This quote from the introduction of the article deals with the same idea: to prove aspects of life by constructing it artificially. That means, like in the case of the firm that one develops a model that shows the behavior of the thing. When this is sufficiently recognized then it must be a firm. This train of thought reminds me of that of Wolfam who considers behavior of a system interesting if it produces interesting pictures, a visual check. This is sufficient because the processes at the basis o our powers of perception are the same as those that generate the behavior in focus.
‘2. The
Autonomy Viewpoint
Proposition 1:
Organisms are fundamentally a process of
constitution of an identity.
(a) By identity I intend here a unitary quality, a coherence of some kind. It is not meant as a static structural description (it is a process), nor as carrying a mentalistic or psychological connotations (it is identity
in a generalized not a personalistic sense).
(b) The nature of this process is always one of a operational closure (Varela, 1979), that is, a circular
reflexive interlinking process, whose primary effect is its own
production.
(c) It is this
operational closure which gives rise to an emergent or global
coherence, without the need of a “central controller,” hence the
identity I have in mind here is nonsubstantially localized, and yet
perfectly able to generate interactions.
(d) An essential
key here is, of course, what we have recently learned about
“emergent” properties in various complex systems.
(e) Different
organisms differ in the kinds of multifarious identity mechanisms
they have, due to their unique evolutionary pathways.’
One side of the coin
is the identity as a kind of coherence emerged from the multitude
that is now itself capable of interacting.
‘Proposition 2:
The organism’s emergent identity gives, logically and
mechanistically, the point of reference for a domain of interactions.
(a) The living
identities are produced by some manner of closure, but what is
produced is an emerging interactive level. The interactions have
relevance and consequences for the unitary identity, although
mechanistically all interactions occur both at component level and
unity’s level.
(b) The
configurations of a level of interaction for the entire unit
creates a perspective from which an interaction can occur. In
other words, this is the source for informational, intentional, or
semantic values to all living organisms.
(c) This entails that living systems bring forth significance: organisms are autonomous, not heteronomously
directed.’
The
identity determines (is the reference for) which interactions the
unity can do.
P1
and P2 say that the identity of an organismic unity ensures that it
can both cognize and be cognized.
‘More precisely defined: An autopoietic system is organized (defined as unity) as a network of processes of production (synthesis and destruction) of components such that these components: (i) continuously
regenerate and realize the network that produces them, and (ii)
constitute the system as a distinguishable unity in the domain in
which they exist.’
The
system is a network of processes of production of components that
reproduce the network and constitute the system as a distinguishable
unity. AP captures processes that generate the identity of the living
and makes a distinction possible from non-living: self-produced
identity. It will keep in play as long as it can remain operationally
closed. All of the above is tricky because it is only about biology.
‘Second,
I take here the view that reproduction is not intrinsic to
the minimal logic of the living. Reproduction must be
considered as an added complexification superimposed on a more basic
identity, that of an autopoietic unity, a complexification which is
necessary due to the constraints of the early conditions on a
turbulent planet. It is here where particular molecular classes play
a key role, such as nucleic acids. Reproduction is essential for the
longterm viability of the living, but only when there is an identity
can a unit reproduce. In this sense, identity has logical and
ontological priority over reproduction, although not historical
precedence.’
Can
this be an argument to counter the distinction between biological
systems and social systems? Because an important comment always is
that the ss cannot reproduce because they have no means to reproduce.
‘For as long as it exists, the autopoietic organization remains invariant. In other words, one way to spotlight the specificity of autopoiesis is to think of it self-referentially as that organization which maintains the very organization itself as an invariant.’
It
is in fact the organization itself that is invariant because it
manages to keep itself invariant. That which keeps your cells into
your body and that which keeps individual persons showing coherent
behavior. Add to that, also not new: ‘Every class of entities
has an identity which is peculiar to them; the uniqueness of the
living resides in the kind of organization it has.’ Waarom een
bakker nooit een goede slager wordt.
‘Now, the history of biology is, of course, marred by the traditional opposition between the mechanist/reductionists on the one hand and holist/vitalists on the other, a heritage from the biological problem-space of the 19th century. One of the specific contributions of the study of self-organizing mechanisms – of which autopoiesis is a specific instance – is that the traditional opposition
between the component elements and the global properties disappears.
In the simple example of the cellular automaton illustrated above, it
is precisely the reciprocal causality between the local rules of
interactions (i.e., the components rules, which are akin to chemical
interactions) and the global properties of the entity (i.e., its
topological demarcation affecting diffusion and creating local
conditions for reaction) which is in evidence. It appears
to me that this reciprocal causality does much to evacuate the
mechanist/vitalist opposition and allows us to move into a more
productive phase of identifying various modes of self-organization
where the local and the global are braided together explicitly
through this reciprocal causality. Autopoiesis is a prime
example of such dialectics between the local component levels and the
global whole, linked together in reciprocal relation through the
requirement of constitution of an entity that self-separates from its
background. In this sense, autopoiesis as the
characterization of the basic pattern of the living does not fall
into the traditional extremes of either vitalism or reductionism.’
This
explains the micro-to-macro aspect of the autopoiesis theory. And
theref roe the diffusion of the distinction between the components
and the newly emerging unity from the networks of processes.
‘It is
ex-hypothesis evident that an autopoietic system depends on its
physicochemical mileu for its conservation as a separate entity,
otherwise it would dissolve back into it. Whence the intriguing
paradox proper to an autonomous identity: the living system must
distinguish itself from its environment, while at the same time
maintaining its coupling; this linkage cannot be detached since it is
against this very environment from which the organism arises, comes
forth.’
I
have used the formula of Ashby to show that an a is required to do
the calculations and that a is not part of S. And so I concluded that
a, if it cannot be part of S, can only be a part of the environment,
and so the system in focus exists distinct from its environment yet
maintaining its coupling.
‘In defining what it is as unity, in the very same movement it defines what remains exterior to it, that is to say, its surrounding environment. A closer examination also makes it evident that this exteriorization can only be understood, so to speak, from the “inside”: the autopoietic unity creates a perspective from which the exterior is one, which cannot be confused with the physical surroundings as they appear to us as observers, the land of physical and chemical laws simpliciter, devoid of such perspectivism.’
The
system creates its own (not to be confused with ours) perspective on
its environment. The fundamental difference is that, different from
the environment, the system is active.
‘However,
on the other hand the sucrose gradient and flagellar beat are
interesting to analyze only because the entire bacteria points to
such items as relevant: their specific significance as components of
feeding behavior is only possible by the presence and perspective of
the bacteria as a totality. Remove the bacteria as a unit, and all
correlations between gradients and hydrodynamic properties be’
How
can this be translated to the case of a firm? What does the behavior
of a firm point at? And if the firm weren’t there (were removed
from the scene) then what would their environment return to? This is
in fact a question that might belong to the proof of existence of the
firm. The answer would be of the category of: If the firm were
removed from the scene then the people included by its ideas would
return to their normal non firm-induced behavior and as a consequence
the firm would no longer be recognized as a firm.
‘I
believe that this truly dialectical relationship is a key point. In
fact, it might appear as so obvious that we do not appreciate its
deep ramifications. I mean the important distinction between the
environment of the living system as it appears to an observer and
without reference to the autonomous unity – which we shall call
hereafter simply the environment – and the environment for the
system, which is defined in the same movement that gave rise to its
identity and that only exists in that mutual definition –
hereinafter the system’s world.’
I
call the environment as it is perceived by us the observer the
environment of the system. And I call the part of that environment
which is relevant for the system its milieu. The formulation for
the environment must change to the environment with the definition
that part of the world that us the observer perceives as a possibly
relevant background for the system?? But this implies that the milieu
is not a subset of the environment, it can be a different set. Varela
calls our world in which we perceive the system’s existence the
environment and and the system’s environment he calls its world.
‘The difference between environment and world is the surplus of signification which haunts the understanding
of the living and of cognition, and which is at the root of how a
self becomes one.’
‘Its world is where a system becomes and it begets its identity. Once it has become a unity then it internally develops a significance concerning its world that is in a surplus over what we can tell about it: ‘There is no food significance in sucrose except when a bacteria swims upgradient and its metabolism uses the molecule in a way that allows its identity to continue’.
‘What the autopoietic system does – due to its very mode of
identity – is to constantly confront the
encounters (perturbations, shocks, coupling) with its environment
and treat them from a perspective
which is not intrinsic to the encounters themselves.’
I must try to adapt this to the making of distinctions and then the erasing of them. But that seems to be very close to the adaptation processes: once a distinction is made then how does the organism ensure that it cannot damage it? It can only make itself and so it makes itself so that it is not damaged. If this is a temporary thing of its present AP organization it is adaptation and if its operational closure changes then it is accommodation: ‘If we invert our perspective, this constant bringing forth of signification is what we may describe as a permanent lack in the living: it is constantly bringing forth a signification that is missing, not pregiven or
pre-existent.’
‘The source for this world-making is always the breakdowns in
autopoiesis, be they minor, like changes in concentration of some
metabolite, or major, like disruption of the boundary. Due to the
nature of autopoiesis itself – illustrated in the membrane repair
of the minimal simulated example above – every breakdown can be
seen as the initiation of an action on what is missing on the part of
the system so that identity might be maintained.’
This I know but it is well-written in the sense of the breakdown of AP.
‘In brief, this permanent, relentless action on
what is lacking becomes, from the observer side, the
ongoing cognitive activity of the system, which
is the basis for the incommensurable difference between the
environment within which the system is observed and the world within
which the system operates. This cognitive activity
is paradoxical at its very root. On the one hand the action that
brings forth a world is an attempt to reestablish a coupling with an
environment which defies the internal coherence through encounters
and perturbations. However, such actions, at the same time, demarcate
and separate the system from that environment, giving rise to a
distinct world.’
Quote this! How adaptation and accommodation erase the differences
with the environment. Very important contribution to that part of the
actual business processes.
‘In brief, the term cognitive has two constitutive dimensions:
first its coupling dimension, that is, a
link with its environment allowing for its continuity as
individual entity; second its interpretative
dimension, that is, the surplus of significance a physical
interaction acquires due to the perspective provided by the global
action of the organism.’
How do I understand this?
‘It introduces an explicit alternative to the dominant
computationalist tradition in the study of cognitive properties for
which the central idea is that of processing an external information
successively elaborated to reconstitute a centralized representation.
This fundamental paradigm of the digital computer program will not do
for biology, nor for AI. I have raised this point to caution the
reader against the force of many years of dominance of
computationalism and the consequent tendency to identify the
cognitive self with some computer program or high level computational
description. This will not do. The cognitive self is its own
implementation: its history and its action are of one piece.’
This is an important argument against the use of computationalism as
a framework of theorizing. But I’m not using computation in this
sense, but in the sense of Wolfram and Dodig (I remember?). The
system is its history and its capabilities at the present point. It
is what it is capable of. It is not a set of rules inscribed in it,
it is its rules.
‘Ordinary life is necessarily one of situated, embodied agents,
continually coming up with what to do faced with ongoing parallel
activities in their various perceptuomotor systems. This continual
redefinition of what to do is not at all like a plan, stored in a
repertoire of potential alternatives, but enormously dependent on
contingency, improvisation, and more flexible than planning.
Situatedness means that a cognitive entity has – by defini-tion –
a perspective. This means that it is not related to its environment
“objectively,” that is independently of the system’s location,
heading, attitudes, and history. Instead, it relates to it in
relation to the perspective established by the constantly emerging
properties of the agent itself and in terms of the role such running
redefinition plays in the system’s entire coherence.’
This can be a useful addition in the part of the nomads. Situated as
a perspective of the system which is different from an objective
perspective. An ongoing instantaneous plan of what to do which seems
to be intentional, given the situation of its environment at that
point.
‘However, this coupling is possible only if the encounters are
embraced from the perspective of the system itself. This amounts,
quite specifically, to elaborating an interpretation relative to this
perspective. Whatever is encountered must be valued one way or
another – like, dislike, ignore – and acted on some way or
another – attraction, rejection, neutrality. This basic assessment
is inseparable from the way in which the coupling event encounters a
functioning precept–motor unit, and it gives rise to an intention
that unique quality of living cognition.’
I like this one for the reference to the perception (Like&c.) as
well as the reference to the action (Attraction&c.).
