EMERGENCE AND SELF-ORGANIZATION OF COMPLEX SYSTEMS : THE ROLE OF ENERGY FLOWS AND INFORMATION A PHILOSOPHICAL APPROACH

How order emerges from noise? How higher complexity arises from lower complexity? For what reason a certain number of open systems start interacting in a coherent way, producing new structures, building up cohesion and new structural boundaries? To answer these questions we need to precise the concepts we use to describe open and complex systems and the basic driving forces of self-organization. We assume that self-organization processes are related to the flow and throughput of Energy and Matter and the production of system-specific Information. These two processes are intimately linked together: Energy and Material flows are the fundamental carriers of signs, which are processed by the internal structure of the system to produce system-specific structural Information (Is). So far, the present theoretical reflections are focused on the emergence of open systems and on the role of Energy Flows and Information in a self-organizing process. Based on the assumption that Energy, Mass and Information are intrinsically linked together and are fundamental aspects of the Universe, we discuss how they might be related to each other and how they are able to produce the emergence of new structures and systems.


INTRODUCTION
To respond the basic question of the following paper we consider necessary to give a more precise definition of the concepts we use to describe the process of emergence and selforganization.On the other hand we need to say that we talk about open and complex systems in general abstract way, without dealing with specific physical, biological or social systems.
We try to describe a very basic process, which assumes different qualities at different levels of complexity.So far, concepts like information, signal, signs, and others are used independently of concepts like meaning or understanding in the sense of human communication.

BASIC PHYSICAL CONCEPTS : MASS, MATTER AND ENERGY
Matter is historically one of the oldest concepts closely related to the form of physical objects.On the other hand the term energy comes up only in the 19 th century as a counter-concept to matter and, using the words of C.F.Weizsäcker, as a "substantialisation" of the 17 th century's concept of force. 1 Energy, on the other hand, is often defined as mass in movement.This general concept of energy has two basic and antagonic aspects: a) Energy as Heat, playing the role of a universal "random generator" producing chaos, and Emergence and self-organization of complex systems:the role of energy flows and information a philosophical approach Norbert Fenzl ARTIGO b) Energy as Work, as a kind of order "generator", producing organized, system-specific structures. 2t this point we would like to recall the important statement of Tom Stonier (1992).
He said: what mass is to matter, heat is to energy, organization is to information.In agreement to this, we say that matter is organized mass, or in more precise terms, organized movement of mass.So far, to organize mass the therefore needed energy appears as system specific (useful) work.
We remember also that heat and mass are supposed to appear nearly simultaneously (protons emerge approximately 10 -11 seconds after the supposed Big Bang) with the beginning of the Universe.So we can say that heat, as unorganized movement of mass, is the mother of all forms of energy we know.All the other types of energy are ultimately expressed as work, or as ability to organize mass to matter.
Without going into thermo-dynamical details, for our further understanding we consider that input energy of open systems is basically used in two basic ways: a) to perform (system specific) work and b) to overcome structural inertia, the dissipated part of energy, called entropy.
Finally in our understanding, the concepts of work and entropy are always system specific in the sense that they only make sense "inside" the system and cannot be exported.
For example, entropy cannot be "exported" as entropy, but only as energy, or heat in a wider sense.

OPEN SELF ORGANIZED SYSTEMS
In the present analysis we concentrate our attention specifically on, open, selforganized systems (Fig. 1).
These systems are composed of three basic dimensions of space-time: -The microscopic dimension on the level of the individual elements, -The mesoscopic dimension of the whole structure, limited by the structural boundary.
-The macroscopic dimension of the field of interaction or relevant environment, limited by the system boundary.
These three dimensions of space-time are inseparable parts of open and complex systems.The dialectic relationship between these three dimensions is a basic characteristic of complex systems.

Element
The concept element is related to the smallest unity of the structure, which is still relevant for the mesoscopic characteristics of a system.The elements (also called parts) constitute the microscopic dimension of the system.For example if we talk about some complex organic molecule, the atoms (C, H, or others) are classified as elements.This is not the case of an organism, such as a plant for example, where the concept of element makes sense only if it designates at least a cell, or a society, where element designs the individual member.

Structure
The concept structure is related to the body aspect of a system.Elements are linkes by forces, which guarantee the coherence and cohesion of the structure.The sum of these binding forces (from physical up to even psychological or cultural forces in the case of human society) characterizes the identity of a system and consequently makes the difference to the rest of the Universe by creating a structural boundary, which defines the mesoscopic dimension of the system. 3Structural boundaries are interfaces, assuming a very important role as mediators between the inner and the outer space of open systems.The basic characteristic of the structure is its structural inertia, the resistance of organized matter against movement (changes).
During the vital flow and throughput of energy, part of the energy input is required to overcome structural inertia, producing entropy (heat), which is lost by dissipation.The remaining amount of energy, used to organize (or reorganize) the systemic structures is what we call system specific work.The antagonism between these two fundamental forms of energy seems to be the basic driving force of self-organization.

Field of Interaction
The concept of field of interaction (Wirkungsfeld), or system-relevant environment, 3 Meso -to describe its intermediate position between micro-and macro-dimension of the whole system.

permanently with its relevant environment through the exchange of energy and matter, characterized by energy-input of higher quality (E1) and energy-output of lower quality (E2).
The input-energy is used by the system to: a) Weaken or break up the bonds (the cohesion) between the elements of the systemto overcome the structural inertia -dissipating energy (Entropy).
b) Reorganize the elements with the aim to (re) stabilize the mesoscopic structure by realization of Work (Stonier, 1990).This is the basic process, which gives adaptability to the system with respect to environmental changes.

Energetic-Material Metabolism (EMM)
The complete process of input-transformation (throughput)-output of energy, called energetic-material metabolism (EMM) of the system, imposes specific changes to its inner (microscopic) and outer (macroscopic) space.During their "life time" open systems transform part of their survival-relevant environment, creating a specific macroscopic dimension of space-time, the field of interaction, or also called system-relevant environment, which turns out to be a characteristic and inseparable part of all open complex systems.
The fact, that we include the field of interaction into the concept of system, means that we distinguish between the structuralboundary and the system-boundary.So, open systems cannot be reduced to their structural dimensions and what we call system is necessarily greater than the physical dimensions of its structure.
On one hand the process of EMM produces its corresponding interaction field.On the other hand, the same process obliges the system to react to all changes of its relevant environment.So far, the necessary structural changes are related to the external changes, which are partly caused by the system itself.
Maybe we can recall at this point the analogy between the relationships like: particle/wave, body/mind and mass/field.
A system only can interact with its relevant environment according to the dynamics of its own structural organization, or, according to the dynamics and needs of its own EMM, which functions according to the structural organization of the system and needs to adapt the environment to its specific requirements.The units of these so caused changes in the field of interaction we call, in a very general way, signs, without distinction if these signs are intentional or not.A specific type of structural organization produces signs in its relevant environment and so far, they naturally reflect essential characteristics of the structure, which produces them.

INFORMATION
To define the concept of Information and analyse its role in the process of emergence of new systems, it is necessary to focus briefly on some underlying concepts, like sign, signal, and data.

Signs
Basically, a sign is something that stands for something else.But here we can find different approaches.For example, Korzybski defines sign as a map, which means a territory.
As an example we can mention the different worldwide used signs to design bathrooms, airports, danger, etc.For C. S. Peirce, "a sign is something that stands for something else to someone in some respect".This definition is more complex and Peirce includes the subject in his concept.
Generally we can say that people working with linguistics would say that words are signs: So, a certain word (lets say car) has a potential meaning (what is written in the dictionaries) and a specific meaning (for a specific person) when used in a specific context.
We use the terminology in the following way: Signs stand for something else "in some respect" and do not represent the entire thing or experience to which they refer.For example a footprint, or all kinds of changes in the environment, which can be computed or recognized by the structure of an open and complex system, is considered a sign in Complex System Theory.

Signals
The main two definitions for signal which are satisfying the purpose of our present analysis are: In a most general context of complex systems, changes (differences) of the energy/matter input mean something for the system if they cause perceptible changes in its structural organization.So far, when signs are carried by the EMM input and cause a systemic reaction or structural changes in the system, they are codified as signals.

Data
People working with computer science define generally data as information that has been translated into a convenient form to store, move or process.Relative to today's computers and transmission technology, data is information converted into binary digital form.
In telecommunications, data sometimes means digital-encoded information to distinguish it from analogue-encoded information such as conventional telephone voice calls.
Data can often be sent in packets that arrives separately in pieces.
In the present discussion data is used as the unit of changes (delta dIs) structural Information is going through during its EMM.The word Information itself is composed by in and form, something is put "in-to a form" and seems to be a kind of synthesis between "self formation" and alien induced transformation.So far, we agree in general terms, with all the authors who define Information as a measure of quantity of form, or as a measure of structural organization.But it seems that even on inorganic levels of evolution this is only one aspect of the information concept. 4  On the other hand the concept of information is, at least since the works of Shannon and Weaver, closely related to the idea of transformation, emergence of the new or novelty. 5

The Concept of Information
There is also a large consensus that the concept of information is related to the idea of emergence of difference, which leads us to the concept of bit, as the unit of difference, and so far as unit of information. 6 Now, if we resume the different concepts of Information actually used, we can find at least the following useful definitions: a) Transmission of Information (I) is related to the transmission of Energy (E) and Entropy (S).But (I) is not equal to (E) nor to (S) (Ebeling 1993, Wiener, 1973, Stonier, 1990); b) The emergence of Information is only possible in self organized systems (Fenzl, Hofkirchner, Stockinger) 7 ; c) Information reduces the uncertainty of a system.Information as a measure for difference (Shannon, Weaver, 1949); d) Pragmatic Information requires novelty (in the sense of Shannon) and receptivity (in the sense of Weizsäcker, 1979) ; e) Ayres, (1994) distinguishes between two basic forms of Information: -D-Information (D -doubt) -SR-Information (SR -survival relevant) f) Information is neither matter nor energy (Wiener 1973); g) Structural Information measures the complexity of a system (Stonier, 1990).Basically we consider the definition of Stonier (1990) the most adequate.But in a very general way, all these concepts can be grouped basically into 3 different types of Information.
1. Structural Information (Is): Information, which represents the structural organization and the functionality of a system.

Pragmatic Information (Ipr):
Information, which appears at a mesoscopic level and represents the way system structures act on its relevant environment.

Potential Information (Ipt):
Information that exists only in potential form, such as a set of signs, not yet received and organized to structural Information by the system (or co-systems).
It is important to point out, that the emergence of irreversible differences in evolution shows a consistent internal logic: we need to admit some logical relation between the past, the present and the future to be able to talk about information.This step leads us directly to irreversibility and probability as basic parts of evolution and of the concept of Information. 8  Since open systems need to maintain its metabolism, they require permanent interaction with its environment.So far, the cycle of inputprocessingoutput of energy flows is essential and nothing can reach the structural space of such a system without energy flows.
Following the previously discussed definitions, we resume that: -Signs are produced (as changes, differences) in the relevant environment by metabolic activities of a system, -If signs, carried and transmitted by EMM energy flows are strong enough to cause structural changes, they are codified as signals and produce the actualisation of structural information.
Emergence and self-organization of complex systems:the role of energy flows and information a philosophical If we consider, that the same process occurs in (B) with respect to (A), and (B) reacts on (A), the first step of a coherent interaction between both systems is accomplished.Now, each system reacts to the other in its specific way, but they have at least two main possibilities in common: attraction or repulsion with all possible intermediate reactions.
In the case of attraction, systems with compatible reactions start to "behave" in a coherent way and establish cohesive links.
Finally we can say that open systems don't need to be in direct structural contact to interact; self-organization is intermediated by processes beyond their respective structural boundaries and by corresponding internal changes due to: a) The exchange of energy and matter with their relevant environment; Emergence and self-organization of complex systems:the role of energy flows and information a philosophical approach Norbert Fenzl

b) The permanent actualisation of structural information (Is) and production of pragmatic information (Ipr).

CONCLUSION
To maintain the necessary flexibility to survive external changes, open complex systems must be able to respond internally by reorganizing its micro-state and externally by organizing their environment (macro-state) according to their own patterns of structural organization by setting signs, the smallest possible changes that structural transformation is able to imprint to its relevant environment.
So, structural Information is transmitted in "small energetic units" (signs), and must be "re-assembled", or in other terms, codified by the structure of the receiver system.The exchange of signals between systems requires some overlapping of their respective relevant environment (field of interaction) to create channels, able to transmit the signs through the activity of its EMM.
The incoming signals are compared to the already "embodied" structural information and classified in useful or harmful to the (Ayres, 1994).We also can say in a more "physical" way, that the incoming signals (p.ex.waves) are modifying -and being modified by -the system-specific organization of matter.
the macroscopic dimension of a system.As we know, all open systems are submitted to the same basic cycle: emergence, development, decay and death.During this cycle the structure of open systems suffers characteristic transformations interacting
