6WHAT IS REALITY (FOR AN AGENT)?
- When discussing cognition as a bioinformatic
process of special interest, we use the notion of
agent, i.e. a system able to act on its own
behalf 1. Agency in biological systems has
been explored in 23. The world (reality) as
it appears to an agent depends on the type of
interaction through which the agent acquires
information and on agents own information-processi
ng 1. - Groups of agents communicate by exchanging
messages (information) that help them coordinate
their actions based on the (partial) information
they possess and share as a part of social
cognition.
7COGNITION AS LIFE
- Agency and cognition is a property of all living
organisms. - Agents themselves can consist of networks of
agents, recursively. A single biological cell
consists of network of agents. Networks of cells
form tissues that form organs that form organisms
that organize in ecologies. - The question is how artifactual agents should be
built in order to possess different degrees of
cognition and eventually even consciousness. Is
it possible at all, for an artifactual agent to
be cognitive given that cognition in living
organisms is a deeply biologically rooted process
connected to survival?
8LANGUAGE AS A TOOL OF HIGH LEVEL COGNITION
- Increasing levels of cognition developed in
living organisms evolutionary, starting from
basic automatic minimally adaptive behaviours
such as found in bacteria and even insects (even
though insects have nervous system and brain,
they lack the limbic system that controls
emotional response to physical stimuli,
suggesting they don't process physical stimuli
emotionally) to increasingly complex behaviour in
higher organisms such as mammals.
9LANGUAGE AS A TOOL OF HIGH LEVEL COGNITION
- Recent advances in natural language processing,
such as Watson computer that wins Geopardy,
present examples of developments towards machines
capable of both understanding natural language
and speaking in a human way. - Along with reasoning, language is often
considered a high-level cognitive activity that
only humans are capable of. - Can AI jump over evolutionary steps in the
development of cognition and base language use on
pure machine learning from vast data sets?
10INFO-COMPUTATIONAL FRAMEWORK FOR STUDY OF
COGNITION
- The framework for the discussion here is the
computing nature in the form of
info-computationalism. - It takes reality to be information for an agent
with a dynamics of information understood as
computation. - Information is a structure and computation its
dynamics. - Information is observer relative and so is
computation. 145
11INFO-COMPUTATIONAL FRAMEWORK FOR STUDY OF
COGNITION
- Cognition is studied as information processing in
such simple organisms as bacteria 6, 7 as
well as cognitive processes in other, more
complex multicellular life forms. - We discuss computational mind and consciousness
that have recently been widely debated in the
work of Giulio Tononi 8 and Christoph Koch. 9
12INFO-COMPUTATIONAL FRAMEWORK FOR STUDY OF
COGNITION
- While the idea that cognition is a biological
process in all living organisms, as argued by
Humberto Maturana and Francisco Varela 10,
11, it is not at all clear that all cognitive
processes in different kinds of organisms are
accompanied by anything akin to (human)
consciousness. - The suggestion is made that cognitive agents with
nervous systems are the step in evolution that
first enabled consciousness of the kind that
humans possess. Argument is advanced that
ascribing consciousness to the whole of the
universe is not justified.
13REALITY AS INFORMATION FOR AN AGENT
- Defining reality as information leaves us with
the question what is it in the world that
corresponds to information and its dynamics,
computation? How do we model information/
computation? Answers are many and they are not
unambiguous.
14INFORMATION, COMPUTATION, COGNITION
- We can compare the present situation regarding
information, computation and cognition with the
history of the development of other basic
scientific concepts. Ideas about matter, energy,
space and time in physics have their history. The
same is true of the idea of number in mathematics
or the idea of life in biology. - So, we should not be surprised to notice the
development in the theory of computation that
goes hand in hand with the development of
information science, cognitive science,
computability, robotics, new computational
devices and new domains of the real world that
can be understood info-computationally.
15LIFE AS INFO-COMPUTATIONAL GENERATIVE PROCESS OF
COGNITION AT DIFFERENT LEVELS OF ORGANIZATION
-
- An agent is an entity capable of acting on its
own behalf. It can be seen as an "actor" in the
Actor model of computation in which "actors" are
the basic elements of concurrent computation
exchanging messages, capable of making local
decisions and creating new actors. Computation is
thus distributed in space where computational
units communicate asynchronously and the entire
computation is not in any well-defined state. (An
actor can have information about other actors
that it has received in a message about what it
was like when the message was sent.) (Hewitt,
2012)
16COGNITIVE INFORMATION PROCESSING THEORY OF
LEARNING ACCORDING TO (GAGNÉ, 1985)
- This is an old and simplistic idea of cognition
as information processing. Missing in this scheme
are feedback loops that are absolutely essential
for cognition and learning. Also missing is
information integration from different sensors
and couplings to actuators. Memory is not a
passive storage but active ingredient in
perception, that is both used for recognition and
anticipation.
Cognitive / Information Processing Theory of
Learning according to (Gagné, 1985)
17WHAT IS REALITY (FOR AN AGENT)?
- Whatever is a reality today, whatever you touch
and believe in and that seems real for you today,
is going to be, like the reality of yesterday, an
illusion tomorrow. - Luigi Pirandello, Six Characters in Search of an
Author - The father, in Six Characters in Search of an
Author, act 3 (1921).
18WHAT IS REALITY (FOR AN AGENT)?
- Would we agree that reality resides in that which
is now, taking into account that our cognitive
apparatus has a finite resolution in time (it
might be as much as 7 seconds delay between
decision and action) where now would be
measured, perhaps in minutes? - What about phenomena that change more slowly? For
such phenomena, now could be days, or years
depending on the phenomenon. But if it is longer
time than what we immediately observe, then the
reality must be based not only on current
perception/understanding but also on memory. - How about reality of future (anticipated) events?
What is a difference of a highly probable event
(such that the Earth revolves the Sun hundred
years from now)?
Chun Siong Soon, Marcel Brass, Hans-Jochen Heinze
John-Dylan Haynes, Unconscious Determinants of
Free Decisions in the Human Brain. Nature
Neuroscience, April 13th, 2008.
19WHAT IS REALITY (FOR AN AGENT)?
- Undoubtedly, we base our decisions/actions on
both memory, current observations and
anticipations. - There is a difference between fiction or virtual
reality and anticipated event based on firm past
evidence. - Degree of reality varies between anticipated
highly probable event and fiction or virtual
representation of any state of similar event.
20COMPUTATION ALL THE WAY DOWN TO QUANTUM
- In his new book, Explaining the Computational
Mind 49 Marcin Milkowski portrays current state
of the ideas about computational mind. The author
presents and systematically dissects number of
misconceptions about what is computation, clearly
placing both neural networks and dynamical
systems into the domain of computational. This is
something that some philosophers would deny,
while practitioners would agree with. 36
21COMPUTATION ALL THE WAY DOWN TO QUANTUM
- Milkowski proposes his own view of computational
models in the following - (O)n my mechanistic account, only one level of
the mechanism the so-called isolated level is
explained in computational terms. The rest of the
mechanism is not computational, and, indeed,
according to the norms of this kind of
explanation, it cannot be computational through
and through. - In this article I argue that this
one-level-approach is not adequate for natural
(intrinsic) computation which appear in hierarchy
of levels. The reason why Milkowski tries to
avoid multiplicity of computational levels is a
fear of computationalism being trivial
22COMPUTATION ALL THE WAY DOWN TO QUANTUM
- In this article I argue that this
one-level-approach is not adequate for natural
(intrinsic) computation which appear in hierarchy
of levels. The reason why Milkowski tries to
avoid multiplicity of computational levels is a
fear of computationalism being trivial - the bottoming-out principle of mechanistic
explanation () says that a phenomenon has to be
explained as constituted by some other phenomenon
than itself. For a pancomputationalist, this
means that there must be a distinction between
lower-level, or basic, computations and the
higher level ones. Should pancomputationalism be
unable to mark this distinction, it will be
explanatorily vacuous. 50
23COMPUTATION ALL THE WAY DOWN TO QUANTUM
- From the above I infer that the model of
computation, which Milkowski assumes in his book,
is a top-down, designed computation. Even though
he rightly argues that neural networks are
computational models and even dynamical systems
can be understood as computational, Milkowski
does not think of intrinsic computation as
grounded in physical process driven by causal
mechanism, characteristics of computing nature.
24COMPUTATION ALL THE WAY DOWN TO QUANTUM
- The fundamental question that worries Milkowski
is the grounding problem that can lead to the
conclusion about triviality. I will argue that
this really is a non-problem. - To start with, grounding is always anchored in an
agent who is the narrator of the explanation. The
narrator choses the granularity of the account.
No picture has infinite granularity and nothing
hinders to imagine even lower levels of existence
(such as more and more elementary particles).
This means that grounding is done over and over
again in all sciences.
25COMPUTATION ALL THE WAY DOWN TO QUANTUM
- When constructing computational models,
Milkowskis focus on only one layer is
pragmatically justified, but not a matter of
principle. Even though one can reconstruct many
intrinsic computational layers in the human brain
(depending on the granularity of the account),
for an observer/narrator often one layer is in
focus at a time. In such simplified models the
layers above and below, even though
computational, are sketchy and used to represent
constraints and not mechanisms. That is at least
the case in designed computation as found in
conventional computers. But e.g. looking at the
experimental work of Subrata Ghosh et al.
building a functional model of brain, we find
twelve-layer computational architecture applied.
51
26COMPUTATION ALL THE WAY DOWN TO QUANTUM
- What is at stake in a theory of implementation?
The main problem seems to me exactly the
opposite. - It is not so interesting to study how brain
implements computation top-down (how do we know
112) but how intrinsic information processing,
that is evidently going on in the brain can be
interpreted as computation. What are the
characteristics of that new kind of computation
that information processes in the brain
constitute?
27COMPUTATION ALL THE WAY DOWN TO QUANTUM
- In that sense of bottom-up intrinsic computation
Chalmers characterization holds, 54 p. 326 - A physical system implements a given computation
when the causal structure of the physical system
mirrors the formal structure of the computation.
- This position is called the Standard Position
(SP) by Sprevak. 55 p. 112. It is applicable to
intrinsic computation (bottom up,
natural/intrinsic), but not to designed
conventional computation (top-down) as this
mirroring would be a very complex process of
interpretation, coding, decoding and
interpretation again. - Thus, not only neurons and whole brains compute
(in the framework of computing nature) but also
the rest of nature computes at variety of levels
of organization.
28COMPUTATIONAL MODELS OF MIND EXCULPATED
- Sprevaks 55 p. 108 concerns about
computationalism - (R1) Clarity Ultimately, the foundations of our
sciences should be clear. Computationalism is
suspected to lack clarity. - (R2) Response to triviality arguments (O)ur
conventional understanding of the notion of
computational implementation is threatened by
triviality arguments. Computationalism is
accused of triviality. - (R3) Naturalistic foundations The ultimate aim
of cognitive science is to offer, not just any
explanation of mental phenomena, but a
naturalistic explanation of the mind.
Computationalism is questioned for being formal
and unnatural.
29COMPUTATIONAL MODELS OF MIND EXCULPATED
- Let me summarize the distinction between
intrinsic /natural/ spontaneous computation and
designed computation used in our technological
devices. - In the info-computationalism, that is a variety
of pancomputationalism, physical nature
spontaneously performs different kinds of
computations (information dynamics) at different
levels of organization. This is intrinsic,
natural computation and is specific for a given
physical system. Intrinsic computation(s) of a
physical system can be used for designed
computation, such as one found in computational
machinery, but it is far from all computation
that can be found in nature.
30COMPUTATIONAL MODELS OF MIND EXCULPATED
- Why is natural computationalism not vacuous?
- For the same reason that physics is not vacuous
which makes the claim that the entire physical
universe is material. Now we will not enter the
topic of ordinary matter-energy vs. dark
matter-energy. Those are all considered to be the
same kind of phenomena natural phenomena that
must be studied with methods of physics. - Why is natural computationalism not vacuous? For

studied with methods of physics.
31WHY PANCOMPUTATIONALISM IS USEFUL AND PANPSYCHISM
IS NOT
- Some computational models of consciousness 8,
58, 59, 9 seem to lead to panpsychism - a
phenomenon defined as follows - Panpsychism is the doctrine that mind is a
fundamental feature of the world which exists
throughout the universe. 60
32WHY PANCOMPUTATIONALISM IS USEFUL AND PANPSYCHISM
IS NOT
- Pancomputationalism (natural computationalism,
computing nature) is the doctrine that whole of
the universe, every physical system, computes. In
the words of 61 - Which physical systems perform computations?
According to pancomputationalism, they all do.
Even rocks, hurricanes, and planetary systems
contrary to appearances are computing systems.
Pancomputationalism is quite popular among some
philosophers and physicists.
33WHY PANCOMPUTATIONALISM IS USEFUL AND PANPSYCHISM
IS NOT
- Info-computationalism starts bottom-up, from
natural processes understood as computation. It
means that computation appears as quantum,
chemical, biological-cognitive, etc. - Only those transformations of informational
structures that correspond to intrinsic processes
in natural systems qualify as computation.
34WHY PANCOMPUTATIONALISM IS USEFUL AND PANPSYCHISM
IS NOT
- Given the argument for info-computational
modelling of nature, and the argument that every
living organism possesses some extent of
cognition one can ask why should we not do
similar move and ascribe consciousness to the
whole of the universe (hypothesis called
panpsychism)? Searle describes consciousness as
follows - Consciousness consists of states of awareness
or sentience or feeling. These typically begin in
the morning when you wake up from a dreamless
sleep and go on all day until you go to sleep or
otherwise become 'unconscious.' 62
35WHY PANCOMPUTATIONALISM IS USEFUL AND PANPSYCHISM
IS NOT
- The simple answer why panpsychism is not a good
idea is in the case of panpsychism we have no
good model. Unlike computational models of
physical and thus biological and cognitive
processes we have no good psychical models. - In fact only naturalists accounts of
consciousness provide models, others prefer to
see consciousness as totally inexplicable in
rational terms, a mystery. - From the naturalist, knowledge generation point
of view, trying to understand everything as
psyche got it backwards we do not know what to
do after the very first move, other than to say
that it is mysterious.
36WHY PANCOMPUTATIONALISM IS USEFUL AND PANPSYCHISM
IS NOT
- The simple answer why panpsychism is not a good
idea is in the case of panpsychism we have no
good model. Unlike computational models of
physical and thus biological and cognitive
processes we have no good psychical models. - In fact only naturalists accounts of
consciousness provide models, others prefer to
see consciousness as totally inexplicable in
rational terms, a mystery. - From the naturalist, knowledge generation point
of view, trying to understand everything as
psyche got it backwards we do not know what to
do after the very first move, other than to say
that it is mysterious.
37WHY PANCOMPUTATIONALISM IS USEFUL AND PANPSYCHISM
IS NOT
- On the contrary, if we try to understand psyche
or better to say mind and consciousness as
manifestations of physical info-computational
processes in the nervous system of a cognizing
agent, we immediately have an arsenal of
modelling tools to address the problem with and
successively and systematically learn more about
it, even construct artefacts (such as cognitive
robots) and test it.
38WHY PANCOMPUTATIONALISM IS USEFUL AND PANPSYCHISM
IS NOT
- That is the main reason why panpsychism is not a
good scientific hypothesis. Instead of opening
all doors for investigation, it declares
consciousness permeating the entire universe and
that's it. One can always generalize concepts if
they lead to better understanding and enable
further modelling. But generalizations of the
idea of psyche is akin to homeopathic procedure
diluting it to concentrations close to zero, and
that will not give us anything in terms of
understanding of mechanisms of mind. - Moreover, as a theory panpsychism belongs to
medieval tradition that which is to be
explained is postulated. I wonder how would
anyone ever get unconscious in a conscious
universe? What would be the difference between
human consciousness and the consciousness of a
bacterium or even a consciousness of vacuum?
39CONCLUSIONS AND FUTURE WORK
- Questions that we posed in the beginning of the
article What is reality for an agent? How does
reality of a bacterium differ from a reality of a
human brain? Do we need representation in order
to understand reality? led us to the discussion
of info-computational models of cognition and
consciousness. - When talking about models of cognition, the very
mention of computationalism typically evokes
reactions against Turing machine model of the
brain and perceived determinism of computation.
Neither of those two problems affects natural
computation or computing nature where model of
computation is broader than deterministic symbol
manipulation.
40CONCLUSIONS AND FUTURE WORK
- Computing nature consists of physical structures
that form levels of organization, on which
computation processes differ. It has been argued
that on the lower levels of organization finite
automata or Turing machines might be adequate,
while on the level of the whole-brain non-Turing
computation is necessary, according to Andre
Ehresmann 63 and Subrata Ghosh et al. 51
41CONCLUSIONS AND FUTURE WORK
- Finally, an argument is advanced that the idea of
panpsychism as a consequence of computational
models by no means should be understood as
necessary. It rather seems to be an artefact of
the model and there is a variety of ways to
correct the model so that non-physical properties
do not follow.
42CONCLUSIONS AND FUTURE WORK
- For the future a lot of work remains to be done,
especially on the connections between the low
level cognitive processes and the high level
ones. It is important to find relations between
cognition and consciousness and the detailed
picture of info-computational mechanisms behind
those phenomena.

49ADDITIONAL MATERIAL
50ACTOR MODEL OF CONCURRENT DISTRIBUTED COMPUTATION
In the Actor Model Hewitt, Bishop and Steiger
1973 Hewitt 2010, computation is conceived as
distributed in space, where computational devices
communicate asynchronously and the entire
computation is not in any well-defined state.
(An Actor can have information about other Actors
that it has received in a message about what it
was like when the message was sent.) Turing's
Model is a special case of the Actor Model.
(Hewitt, 2012)
Hewitts computational devices are conceived as
computational agents informational structures
capable of acting on their own behalf.
51ACTOR MODEL OF CONCURRENT DISTRIBUTED COMPUTATION
- Actors are the universal primitives of
concurrent distributed digital computation. In
response to a message that it receives, an Actor
can make local decisions, create more Actors,
send more messages, and designate how to respond
to the next message received. - For Hewitt Actors rise to the level of Agenthood
when they competently process expressions - for commitments including the following
- Contracts, Announcements, Beliefs, Goals,
Intentions, Plans, - Policies, Procedures, Requests, Queries.
- In other words, his agents are human-like.
52LIFE AS INFO-COMPUTATIONAL GENERATIVE PROCESS OF
COGNITION AT DIFFERENT LEVELS OF ORGANIZATION
- This paper presents a study within
info-computational constructive framework of the
life process as ltknowledgegt generation in living
agents from the simplest living organisms to the
most complex ones. Here ltknowledgegt of a
primitive life form is very basic indeed it is
ltknowledgegt how to act in the world. An amoeba
ltknowsgt how to search for food and how to avoid
dangers.
53LIVING AGENTS
- A living agent is a special kind of actor that
can reproduce and that is capable of undergoing
at least one thermodynamic work cycle. (Kauffman,
2000) - This definition differs from the common belief
that (living) agency requires beliefs and
desires, unless we ascribe some primitive form of
ltbeliefgt and ltdesiregt even to a very simple
living agents such as bacteria. The fact is that
they act on some kind of ltanticipationgt and
according to some ltpreferencesgt which might be
automatic in a sense that they directly derive
from the organisms morphology. Even the simplest
living beings act on their own behalf.
54LIVING AGENTS
- Although a detailed physical account of the
agents capacity to perform work cycles and so
persist in the world is central for understanding
of life/cognition, as (Kauffman, 2000) (Deacon,
2007) have argued in detail, this work is
primarily interested of the info-computational
aspects of life. - Info-computational approach takes information an
computation to be the two basic building block
concepts, corresponding to structure and process,
being and becoming. - Given that there is no information without
physical implementation (Landauer, 1991),
computation as the dynamics of information is the
execution of physical laws.
55LIVING AGENTS
- Kauffmans concept of agency (also adopted by
Deacon) suggests the possibility that life can be
derived from physics. That is not the same as to
claim that life can be reduced to physics that is
obviously false. - However, in deriving life from physics one may
expect that both our understanding of life as
well as physics will change. - We witness the emergence of information physics
(Goyal, 2012) (Chiribella, G. DAriano, G.M.
Perinotti, 2012) as a possible reformulation of
physics that may bring physics and life/cognition
closer to each other. This development smoothly
connects to info-computational understanding of
nature (Dodig-Crnkovic Giovagnoli, 2013).
56THE COMPUTING NATURE
- Life can be analyzed as cognitive processes
unfolding in a layered structure of nested
information network hierarchies with
corresponding computational dynamics (information
processes) from molecular, to cellular,
organismic and social levels. - In order to construct life as cognitive process
we will introduce two fundamental theories about
the nature of the universe and propose their
synthesis - The first one with focus on processes is the
idea of computing universe (naturalist
computationalism/ pancomputationalism) in which
one sees the dynamics of physical states in
nature as information processing (natural
computation).
57THE COMPUTING NATURE
- The parallel fundamental theory with focus on
structures is Informational structural realism
(Floridi, 2003) that takes information to be the
fabric of the universe (for an agent). - Combining definitions of Bateson
- information is a difference that makes a
difference (Bateson, 1972) - and Hewitt
- Information expresses the fact that a system is
in a certain configuration that is correlated to
the configuration of another system. Any physical
system may contain information about another
physical system. (Hewitt, 2007), we get - information is defined as the difference in one
physical system that makes the difference in
another physical system.
58THE COMPUTING NATURE
- information is defined as the difference in one
physical system that makes the difference in
another physical system. - This implies relational character of information
and thus agent-dependency in agent-based or
actor model. - As a synthesis of informational structural
realism and natural computationalism,
info-computational structuralism adopts two basic
concepts information (as a structure) and
computation (as a dynamics of an informational
structure) (Dodig-Crnkovic, 2011) (Chaitin,
2007). - In consequence the process of dynamical changes
of the universe makes the universe a huge
computational network where computation is
information processing. (Dodig-Crnkovic
Giovagnoli, 2013) Information and computation are
two basic and inseparable elements necessary for
naturalizing cognition and ltknowledgegt.
(Dodig-Crnkovic, 2009)
59THE COMPUTING NATURE
-
- Agents - systems able to act on their own behalf
and make sense (use) of information are of
special interest with respect to ltknowledgegt
generation. - This relates to the ideas of participatory
universe, (Wheeler, 1990) endophysics (Rössler,
1998) and observer-dependent ltknowledgegt
production.
60MORPHOLOGICAL COMPUTATION FROM SIMPLEST TO THE
MOST COMPLEX ORGANISMS
- In the computing nature, ltknowledgegt generation
should be studied as a natural process. That is
the main idea of Naturalized epistemology (Harms,
2006), where the subject matter is not our
concept of ltknowledgegt, but the knowledge itself
as it appears in the world as specific
informational structures of an agent. - Maturana and Varela were the first to suggest
that knowledge is a biological phenomenon. They
argued that life should be understood as a
process of cognition, which enables an organism
to adapt and survive in the changing environment.
(Maturana Varela, 1980)

63Info-computational framework connecting
informational structures and processes from
quantum physics to living organisms and
societies
- Nature is described as a complex informational
structure for a cognizing agent. - Computation is information dynamics (information
processing) constrained and governed by the laws
of physics on the fundamental level. - Information is the difference in one information
structure that makes a difference in another
information structure.
64COMPUTING NATURE
- The basic idea of computing nature is that all
processes taking place in physical world can be
described as computational processes from the
world of quantum mechanics to living organisms,
their societies and ecologies. Emphasis is on
regularities and typical behaviors. - Even though we all have our subjective reasons
why we move and how we do that, from the
bird-eye-view movements of inhabitants in a city
show big regularities. - In order to understand big picture and behavior
of societies, we take computational approach
based on data and information. - See the work of Albert-László Barabási who
studies networks on different scales - http//www.barabasilab.com/pubs-talks.php
65COMPUTATION AS INFORMATION PROCESSING
- Info-computational approach takes information as
the primary stuff of the universe, and
computation is as time-dependent behavior
(dynamics) of information. - This results in a Dual-aspect Universe
informational structure with computational
dynamics. (Info-Computationalism, Dodig Crnkovic) - Information and computation are closely related
no computation without information, and no
information without dynamics (computation).
66COGNITION AS COMPUTATION
Information/computation mechanisms are
fundamental for evolution of intelligent agents.
Their role is to adapt the physical structure and
behavior that will increase organisms chances of
survival, or otherwise induce some other behavior
that might be a preference of an agent. In this
pragmatic framework, meaning in general is use,
which is also the case with meaning of
information.
