What is Universe? What is Knowledge? What is Science?
Based on an enormous boost of distributed cognition and extended mind of humanity we witness a major paradigm shift in our understanding of the universe and our place in itand our place in it.
This big picture is important it t th f kas it sets the framework
for how we think.
That is why not only theory y y yof particular sciences or specific phenomena but even philosophy of naturemakes the differencemakes the difference.(And empirical data are as well known theory-laden, even by implicit theory)

Natural Philosophy
Natural philosophy (Philosophia Naturalis) as a study of nature and the physicalNatural philosophy (Philosophia Naturalis) as a study of nature and the physical
universe was dominant before the development of modern science in the 19th century.
Newton was natural philosopher. At older universities, long-established Chairs of
Natural Philosophy are nowadays occupied mainly by physics professors. *
At present, interesting complexity phenomena are studied on the intersection of several
research fields such as computing, biology, neuroscience, cognitive science,
philosophy physics and similar information/computation intensive fields which mightphilosophy, physics, and similar information/computation intensive fields which might
again form a core of a new life-centric natural philosophy, which will include human as
natural being.

Information as a Fabric of Reality
According to Gregory Bateson, Information is the difference that makes a difference.

Dennett And John Haugeland see information as means of unification:“It is tempting to suppose that some concept of information could serve eventually to unify mind, matter, and meaning in a single theory.” Daniel C.

Structure vs. Process
According to Informational structural Realism (Floridi, Sayre) information is the fabric of reality
As we can observe, structures in the world constantly change.
The knowledge of structures is half a story The other half isThe knowledge of structures is half a story. The other half is understanding processes, dynamics.

Info-computationalism
Information and computation are two interrelated and mutually defining phenomena – there is no computation without information (computation understood as information processing) and vice(computation understood as information processing), and vice versa, there is no information without computation (information as a result of computational processes).
Being interconnected, information is studied as a structure, while computation presents a process on an informational structure.
In order to learn about foundations of information, we must also study computation.

Computation is generally defined as information processing.(See Burgin, M., Super-Recursive Algorithms, Springer Monographs in Computer Science, 2005)p , )

Models of Computation. Beyond Turing Machine Model
With the advent of computer networks, which are the main paradigm of
computing today, the model of a computer in isolation, represented by a
Universal Turing Machine, has become insufficient.
The basic difference between an isolated computing box and a network of
computational processes (nature itself understood as a computational
mechanism) is the interactivity of computation. The most general
computational paradigm today is interactive computing (Wegner, Goldin).
M d l f C i T i M hi Li i S lf G i SModels of Computation. Turing Machine Limits. Self-Generating Systems
Complex biological systems must be modeled as self-referential, self-organizing "component-systems" (George Kampis) which are self generating and whose(George Kampis) which are self-generating and whose behavior, though computational in a general sense, goes far beyond Turing machine model.
“a component system is a computer which, when executing its operations (software) builds a new hardware.... [W]e have a computer that re-wires itself in a hardware-software interplay: the hardware defines the software and the software defines new hard are Then the circle starts again ”hardware. Then the circle starts again.” (Kampis, p. 223 Self-Modifying Systems in Biology and Cognitive Science)

The challenge to deal with computability in the real world/physical computing
(such as computing on continuous data, biological computing/organic
ti t ti ll t l ti ) h b htcomputing, quantum computing, or generally natural computing) has brought
new understanding of computation.
Natural computing has different criteria for success of a computation, halting
problem is not a central issue but instead the adequacy of the computationalproblem is not a central issue, but instead the adequacy of the computational
response in a network of interacting computational processes/devices.

Info-computationalism aims at connecting non-living and living nature in a unified natural philosophy.p p y
Among others observer is integrated in the scientific epistemology.That means that we need to understand how an observing agent interacts with the system and what knowledge might be constructed from that kind of interaction.

InfoInfo--computationalism Applied: Epistemology Naturalizedcomputationalism Applied: Epistemology Naturalized
Naturalized epistemology is an idea that knowledge may be studied as a
natural phenomenon -- that the subject matter of epistemology is not our
concept of knowledge, but the knowledge itself. (Feldman, Kornblith, Stich)
“If the stimulation of his sensory receptors is all the evidence anybody has

Naturalist Understanding of Cognition
According to Maturana and Varela (1980) even the simplest organisms possess
cognition and their meaning-production apparatus is contained in their g g
metabolism. Of course, there are also non-metabolic interactions with the
environment, such as locomotion, that also generates meaning for an organism by
changing its environment and providing new input data.
M t d V l ’ d t di th t ll li i i hMaturana and Varela’s understanding that all living organisms have some
cognition, in some degree, is the most suitable basis for the computationalist
account of the naturalized evolutionary epistemology. y p gy
Info-computational Account of Knowledge Generation
Natural computing as a new paradigm of computing goes
beyond the Turing Machine model and applies to all physical y g pp p y
processes including those going on in our brains.
To do so computer scientists must draw on the expertise in
subjects not usually associated with computing, including
organic chemistry, molecular biology, bioengineering, and
smart materials.
Info computational Account of Knowledge GenerationInfo-computational Account of Knowledge Generation
At the physical level, living beings are open complex computational
systems in a regime on the edge of chaos, characterized by maximal
informational content. Complexity is found between orderly systems

random systems with low compressibility and high information content.

The essential feature of cognizing living organisms is their ability to
manage complexity, and to handle complicated environmental
conditions with a variety of responses which are results of adaptation,
variation, selection, learning, and/or reasoning. (Gell-Mann)
Cognition as Restructuring* of an Agent in the Interaction with the Environment
As a result of evolution, increasingly complex living organisms arise that are able to survive
and adapt to their environment. It means they are able to register inputs (data) from the
environment, to structure those into information, and in more developed organisms into
knowledge. The evolutionary advantage of using structured, component-based approaches
is improving response-time and efficiency of cognitive processes of an organism.is improving response time and efficiency of cognitive processes of an organism.
The Dual network model, suggested by Goertzel for modeling cognition in a living organism
describes mind in terms of two superposed networks: a self-organizing associative memory
network, and a perceptual-motor process hierarchy.
*This is morphological computing
Cognition as Restructuring of an Agent in the Interaction with the Environment
Naturalized knowledge generation acknowledges the body as our basic cognitive instrument.
All iti i b di d iti i b th i i d h (Gä d fAll cognition is embodied cognition, in both microorganisms and humans (Gärdenfors,
Stuart). In more complex cognitive agents, knowledge is built upon not only reaction to input
information, but also on intentional choices, dependent on value systems stored and
organized in agents memory.
It is not surprising that present day interest in knowledge generation places information and p g p y g g p
