Self-organization
From Wikipedia, the free encyclopedia
Self-organization is the process where a structure or pattern appears in a system without a central authority or external element imposing it. This globally coherent pattern appears from the local interaction of the elements that makes up the system, thus the organization is achieved in a way that is parallel (all the elements act at the same time) and distributed (no element is a coordinator).
Overview
The most robust and unambiguous examples
[1] of self-organizing systems are from the
physics of non-equilibrium processes. Self-organization is also relevant in
chemistry, where it has often been taken as being synonymous with
self-assembly. The concept of self-organization is central to the description of biological systems, from the subcellular to the ecosystem level. There are also cited examples of "self-organizing" behaviour found in the literature of many other disciplines, both in the
natural sciences and the
social sciences such as
economics or
anthropology. Self-organization has also been observed in mathematical systems such as
cellular automata.
Sometimes the notion of self-organization is conflated with that of the related concept of
emergence.
[citation needed] Properly defined, however, there may be instances of self-organization without emergence and emergence without self-organization, and it is clear from the literature that the phenomena are not the same. The link between emergence and self-organization remains an active research question.
Self-organization usually relies on four basic ingredients
[2]:
- Strong dynamical non-linearity, often though not necessarily involving Positive feedback and Negative feedback
- Balance of exploitation and exploration
- Multiple interactions
History of the idea
The idea that the
dynamics of a system can tend by themselves to increase the inherent order of a system has a long history. One of the earliest statements of this idea was by the philosopher
Descartes, in the fifth part of his
Discourse on Method, where he presents it hypothetically.
[citation needed] Descartes further elaborated on the idea at great length in his unpublished work
The World.
The ancient
atomists (among others) believed that a designing intelligence was unnecessary, arguing that given enough time and space and matter, organization was ultimately inevitable, although there would be no preferred tendency for this to happen. What Descartes introduced was the idea that the ordinary laws of nature
tend to produce organization
[citation needed] (For related history, see Aram Vartanian,
Diderot and Descartes).
Beginning with the 18th century
naturalists, a movement arose that sought to understand the "universal laws of form" in order to explain the observed forms of living organisms. Because of its association with
Lamarckism, their ideas fell into disrepute until the early 20th century, when pioneers such as
D'Arcy Wentworth Thompson revived them. The modern understanding is that there are indeed universal laws (arising from fundamental physics and chemistry) that govern growth and form in biological systems.
Originally, the term "self-organizing" was used by
Immanuel Kant in his
Critique of Judgment, where he argued that teleology is a meaningful concept only if there exists such an entity whose parts or "organs" are simultaneously ends and means. Such a system of organs must be able to behave as if it has a mind of its own, that is, it is capable of governing itself.
| “ | In such a natural product as this every part is thought as owing its presence to the agency of all the remaining parts, and also as existing for the sake of the others and of the whole, that is as an instrument, or organ... The part must be an organ producing the other parts—each, consequently, reciprocally producing the others... Only under these conditions and upon these terms can such a product be an organized and self-organized being, and, as such, be called a physical end. | ” |
The term "self-organizing" was introduced to contemporary science in 1947 by the psychiatrist and engineer
W. Ross Ashby[3]. It was taken up by the cyberneticians
Heinz von Foerster,
Gordon Pask,
Stafford Beer and
Norbert Wiener himself in the second edition of his "Cybernetics: or Control and Communication in the Animal and the Machine" (MIT Press 1961).
Self-organization as a word and concept was used by those associated with
general systems theory in the 1960s, but did not become commonplace in the scientific literature until its adoption by
physicists and researchers in the field of
complex systems in the 1970s and 1980s.
[4] After 1977's
Ilya Prigogine Nobel Prize, the
thermodynamic concept of self-organization received some attention of the public, and scientific researchers start to migrate from the
cybernetic view to the
thermodynamic view.
Examples
The following list summarizes and classifies the instances of self-organization found in different disciplines. As the list grows, it becomes increasingly difficult to determine whether these phenomena are all fundamentally the same process, or the same label applied to several different processes. Self-organization, despite its intuitive simplicity as a concept, has proven notoriously difficult to define and pin down formally or mathematically, and it is entirely possible that any precise definition might not include all the phenomena to which the label has been applied.
It should also be noted that, the farther a phenomenon is removed from physics, the more controversial the idea of self-organization
as understood by physicists becomes. Also, even when self-organization is clearly present, attempts at explaining it through physics or statistics are usually criticized as
reductionistic.
Similarly, when ideas about self-organization originate in, say, biology or social science, the farther one tries to take the concept into chemistry, physics or mathematics, the more resistance is encountered, usually on the grounds that it implies
direction in fundamental physical processes. However the tendency of hot bodies to get cold (see
Thermodynamics) and by
Le Chatelier's Principle- the
statistical mechanics extension of
Newton's Third Law- to oppose this tendency should be noted.
Self-organization in physics
Convection cells in a gravity field
There are several broad classes of physical processes that can be described as self-organization. Such examples from
physics include:
- self-organizing dynamical systems: complex systems made up of small, simple units connected to each other usually exhibit self-organization
- In spin foam system and loop quantum gravity that was proposed by Lee Smolin. The main idea is that the evolution of space in time should be robust in general. Any fine-tuning of cosmological parameters weaken the independency of the fundamental theory. Philosophically, it can be assumed that in the early time, there has not been any agent to tune the cosmological parameters. Smolin and his colleagues in a series of works show that, based on the loop quantization of spacetime, in the very early time, a simple evolutionary model (similar to the sand pile model) behaves as a power law distribution on both the size and area of avalanche.
- Although, this model, which is restricted only on the frozen spin networks, exhibits a non-stationary expansion of the universe. However, it is the first serious attempt toward the final ambitious goal of determining the cosmic expansion and inflation based on a self-organized criticality theory in which the parameters are not tuned, but instead are determined from within the complex system.[5]
Self-organization vs. entropy
Statistical mechanics informs us that large scale phenomena can be viewed as a large system of small interacting particles, whose processes are assumed consistent with well established mechanical laws such as entropy, i.e., equilibrium thermodynamics. However, “… following the macroscopic point of view the same physical media can be thought of as continua whose properties of evolution are given by phenomenological laws between directly measurable quantities on our scale, such as, for example, the pressure, the temperature, or the concentrations of the different components of the media. The macroscopic perspective is of interest because of its greater simplicity of formalism and because it is often the only view practicable.” Against this background, Glansdorff and
Ilya Prigogine introduced a deeper view at the microscopic level, where “… the principles of thermodynamics explicitly make apparent the concept of irreversibility and along with it the concept of dissipation and temporal orientation which were ignored by classical (or quantum) dynamics, where the time appears as a simple parameter and the trajectories are entirely reversible.”
[6]
As a result, processes considered part of thermodynamically open systems, such as biological processes that are constantly receiving, transforming and dissipating chemical energy (and even the earth itself which is constantly receiving and dissipating solar energy), can and do exhibit properties of self organization far from thermodynamic equilibrium.
A
laser can also be characterized as a self organized system to the extent that normal states of thermal equilibrium characterized by electromagnetic energy absorption are stimulated out of equilibrium in a reverse of the absorption process. “If the matter can be forced out of thermal equilibrium to a sufficient degree, so that the upper state has a higher population than the lower state (population inversion), then more stimulated emission than absorption occurs, leading to coherent growth (amplification or gain) of the electromagnetic wave at the transition frequency.”
[7]
Self-organization in chemistry

atomic force microscopy at right. Image from Strong.
[8]Self-organization in
chemistry includes:
- molecular self-assembly
- reaction-diffusion systems and oscillating chemical reactions
- autocatalytic networks (see: autocatalytic set)
- liquid crystals
- colloidal crystals
- self-assembled monolayers
- micelles
- microphase separation of block copolymers
- Langmuir-Blodgett films
Self-organization in biology
According to
Scott Camazine.. [et al.]:
| “ | In biological systems self-organization is a process in which pattern at the global level of a system emerges solely from numerous interactions among the lower-level components of the system. Moreover, the rules specifying interactions among the system's components are executed using only local information, without reference to the global pattern.[9] | ” |
The following is an incomplete list of the diverse phenomena which have been described as self-organizing in
biology.
- spontaneous folding of proteins and other biomacromolecules
- formation of lipid bilayer membranes
- homeostasis (the self-maintaining nature of systems from the cell to the whole organism)
- pattern formation and morphogenesis, or how the living organism develops and grows. See also embryology.
- the coordination of human movement, e.g. seminal studies of bimanual coordination by Kelso
- the creation of structures by social animals, such as social insects (bees, ants, termites), and many mammals
- flocking behaviour (such as the formation of flocks by birds, schools of fish, etc.)
- the origin of life itself from self-organizing chemical systems, in the theories of hypercycles and autocatalytic networks
- the organization of Earth's biosphere in a way that is broadly conducive to life (according to the controversial Gaia hypothesis)
Self-organization in mathematics and computer science
As mentioned above, phenomena from
mathematics and
computer science such as
cellular automata,
random graphs, and some instances of
evolutionary computation and
artificial life exhibit features of self-organization. In
swarm robotics, self-organization is used to produce emergent behavior. In particular the theory of random graphs has been used as a justification for self-organization as a general principle of complex systems. In the field of
multi-agent systems, understanding how to engineer systems that are capable of presenting self-organized behavior is a very active research area.
Self-organization in cybernetics
Wiener regarded the automatic serial
identification of a
black box and its subsequent reproduction as sufficient to meet the condition of self-organization.
[11] The importance of
phase locking or the "attraction of frequencies", as he called it, is discussed in the 2nd edition of his "
Cybernetics".
[12] Drexler sees
self-replication as a key step in nano and
universal assembly.
By contrast, the four concurrently connected galvanometers of
W. Ross Ashby's
Homeostat hunt, when perturbed, to converge on one of many possible stable states.
[13] Ashby used his state counting measure of
variety[14] to describe stable states and produced the "
Good Regulator"
[15] theorem which requires internal models for self-organized
endurance and
stability.
Warren McCulloch proposed "Redundancy of Potential Command"
[16] as characteristic of the organization of the brain and human nervous system and the necessary condition for self-organization.
Heinz von Foerster proposed Redundancy, R = 1- H/Hmax , where H is entropy.
[17] In essence this states that unused potential communication bandwidth is a measure of self-organization.
In the 1970s
Stafford Beer considered this condition as necessary for
autonomy which identifies self-organization in persisting and
living systems. Using Variety analyses he applied his neurophysiologically derived recursive
Viable System Model to management. It consists of five parts: the monitoring of
performance[18] of the survival processes (1), their management by recursive application of regulation (2),
homeostatic operational control (3) and development (4) which produce maintenance of identity (5) under environmental perturbation. Focus is prioritized by an "algedonic loop" feedback:
[19] a sensitivity to both pain and pleasure.
In the 1990s
Gordon Pask pointed out von Foerster's H and Hmax were not independent and interacted via
countably infinite recursive concurrent
spin processes
[20] (he favoured the
Bohm interpretation) which he called concepts (liberally defined in
any medium, "productive and, incidentally reproductive"). His strict definition of concept "a procedure to bring about a relation"
[21] permitted his theorem "Like concepts repel, unlike concepts attract"
[22] to state a general spin based
Principle of Self-organization. His edict, an exclusion principle, "There are
No Doppelgangers"
[23] means no two concepts can be the same (all interactions occur with different perspectives making time incommensurable for
actors). This means, after sufficient duration as differences assert, all concepts will attract and coalesce as
pink noise and
entropy increases (and see
Big Crunch,
self-organized criticality). The theory is applicable to all organizationally
closed or homeostatic processes that produce
endurance and
coherence (also in the sense of
Reshcher Coherence Theory of Truth with the proviso that the sets and their members exert repulsive forces at their boundaries) through interactions:
evolving,
learning and
adapting.
Pask's
Interactions of actors "hard carapace" model is reflected in some of the ideas of
emergence and
coherence. It requires a
knot emergence topology that produces radiation during interaction with a
unit cell that has a prismatic
tensegrity structure.
Laughlin's
contribution to emergence reflects some of these constraints.
Self-organization in human society
Social self-organization in international drug routes
The self-organizing behaviour of social animals and the self-organization of simple mathematical structures both suggest that self-organization should be expected in human
society. Tell-tale signs of self-organization are usually statistical properties shared with self-organizing physical systems (see
Zipf's law,
power law,
Pareto principle). Examples such as
Critical mass (sociodynamics),
herd behaviour,
groupthink and others, abound in
sociology,
economics,
behavioral finance and
anthropology.
[24]
In social theory the concept of self-referentiality has been introduced as a sociological application of self-organization theory by
Niklas Luhmann (1984). For Luhmann the elements of a social system are self-producing communications, i.e. a communication produces further communications and hence a social system can reproduce itself as long as there is dynamic communication. For Luhmann human beings are sensors in the environment of the system.{p410 Social System 1995} Luhmann developed an evolutionary theory of Society and its subsytems, using functional
analyses and systems
theory. {Social Systems 1995}.
Self-organization in human and computer networks can give rise to a decentralized, distributed, self-healing system, protecting the security of the actors in the network by limiting the scope of knowledge of the entire system held by each individual actor. The
Underground Railroad is a good example of this sort of network. The networks that arise from
drug trafficking exhibit similar self-organizing properties. Parallel examples exist in the world of privacy-preserving computer networks such as
Tor. In each case, the network as a whole exhibits distinctive synergistic behavior through the combination of the behaviors of individual actors in the network. Usually the growth of such networks is fueled by an ideology or sociological force that is adhered to or shared by all participants in the network.
[original research?][citation needed]
In economics
In economics, a
market economy is sometimes said to be self-organizing.
Paul Krugman has written on the role that market self-organization plays in the business cycle in his book "The Self Organizing Economy"
[25].
Friedrich Hayek coined the term
catallaxy to describe a "self-organizing system of voluntary co-operation," in regard to capitalism. Most modern economists hold that imposing
central planning usually makes the self-organized economic system less efficient. By contrast, some socialist economists consider that
market failures are so significant that self-organization produces bad results and that the state should direct production and pricing. Many economists adopt an intermediate position and recommend a mixture of market economy and
command economy characteristics (sometimes called a
mixed economy). When applied to economics, the concept of self-organization can quickly become ideologically-imbued (as explained in chapter 5 of A. Marshall, The Unity of Nature, Imperial College Press, 2002).
In collective intelligence
Visualization of links between pages on a wiki. This is an example of collective intelligence through collaborative editing.
Non-thermodynamic concepts of entropy and self-organization have been explored by many theorists.
Cliff Joslyn and colleagues and their so-called "
global brain" projects.
Marvin Minsky's "
Society of Mind" and the no-central editor in charge policy of the open sourced internet encyclopedia, called
Wikipedia, are examples of applications of these principles - see
collective intelligence.
Donella Meadows, who codified
twelve leverage points that a self-organizing system could exploit to organize itself, was one of a school of theorists who saw human creativity as part of a general process of adapting human lifeways to the planet and taking humans out of conflict with natural processes. See
Gaia philosophy,
deep ecology,
ecology movement and
Green movement for similar self-organizing ideals. (The connections between self-organisation and Gaia theory and the environmental movement are explored in A. Marshall, 2002, The Unity of Nature, Imperial College Press: London).
Self-organization in linguistics
Self-organization refers to a property by which complex systems spontaneously generate organized structures"
[26].
[Full citation needed] It is the spontaneous formation of well organized structures, patterns, or behaviors, from random initial conditions. It is the process of macroscopic outcomes emerging from local interactions of components of the system, but the global organizational properties are not to be found at the local level. The systems used to study this phenomenon are referred to as dynamical systems: state-determined systems. They possess a large number of elements or variables, and thus very large state spaces.
Traditional framework of good science is
Reductionism, in the sense that sub-parts are studied individually to understand the bigger part. However, many natural systems cannot simply be explained by a reductionist study of their parts. Self-organization is not studying the whole structure by breaking it down to smaller sub-parts which are then studied individually. The emphasis of the “self-organization” is, rather, the process of how a super macro global structure evolves from local interactions.
"The self that gets organized should not be just the language ability but the cluster of competencies through which it emerges. These probably include a variety of cognitive, social, affective, and motor skills."
[27][Full citation needed] The human brains, and thus the phenomena of sensation and thought, are also under the strong influence of features of spontaneous organization in their structure. Indeed, the brain, composed of billions of neurons dynamically interacting among themselves and with the outside world, is the prototype of a complex system. A good example of self organization in linguistics is the evolution of
Nicaraguan Sign Language. Examples of linguistic questions in the light of self organization are: e.g. the decentralized generation of lexical and semantic conventions in populations of agents.
[28][Full citation needed][29][Full citation needed];the formation of conventionalized syntactic structures
[30];
[Full citation needed] the conditions under which combinatoriality, the property of systematic reuse, can be selected
[31];
[Full citation needed] shared inventories of vowels or syllables in groups of agents, with features of structural regularities greatly resembling those of human languages
[32][Full citation needed][33][Full citation needed]
Methodology
In many complex systems in nature, there are global phenomena that are the irreducible result of local interactions between components whose individual study would not allow us to see the global properties of the whole combined system. Thus, a growing number of researchers think that many properties of language are not directly encoded by any of the components involved, but are the self-organized outcomes of the interactions of the components.
Building mathematical models in the context of research into language origins and the evolution of languages is enjoying growing popularity in the scientific community, because it is a crucial tool for studying the phenomena of language in relation to the complex interactions of its components. These systems are put to two main types of use: 1) they serve to evaluate the internal coherence of verbally expressed theories already proposed by clarifying all their hypotheses and verifying that they do indeed lead to the proposed conclusions ; 2) they serve to explore and generate new theories, which themselves often appear when one simply tries to build an artificial system reproducing the verbal behavior of humans.
Therefore, constructing operational models to test hypothesis in linguistics is gaining popularity these days. An operational model is one which defines the set of its assumptions explicitly and above all shows how to calculate their consequences, that is, to prove that they lead to a certain set of conclusions.
[edit] In the emergence of language
The emergence of language in the human species has been described in a game-theoretic framework based on a model of senders and receivers of information (Clark 2009
[34], following Skyrms 2004
[35]).
[Full citation needed] The evolution of certain properties of language such as
inference follow from this sort of framework (with the parameters stating that information transmitted can be partial or redundant, and the underlying assumption that the sender and receiver each want to take the action in his/her best interest)
[36].
[Full citation needed] Likewise, models have shown that
compositionality, a central component of human language, emerges dynamically during linguistic evolution, and need not be introduced by biological evolution (Kirby 2000)
[37].
[Full citation needed] Tomasello (1999)
[38][Full citation needed] argues that through one evolutionary step, the ability to sustain culture, the groundwork for the evolution of human language was laid. The ability to ratchet cultural advances cumulatively allowed for the complex development of human cognition unseen in other animals.
[edit] In language acquisition
Within a species' ontogeny, the acquisition of language has also been shown to self-organize. Through the ability to see others as intentional agents (theory of mind), and actions such as '
joint attention,' human children have the scaffolding they need to learn the language of those around them (Tomasello 1999)
[39].
[Full citation needed]
In articulatory phonology
Articulatory phonology takes the approach that speech production consists of a coordinated series of
gestures, called 'constellations,' which are themselves dynamical systems. In this theory, linguistic contrast comes from the distinction between such gestural units, which can be described on a low-dimensional level in the abstract. However, these structures are necessarily context-dependent in real-time production. Thus the context-dependence emerges naturally from the dynamical systems themselves. This statement is controversial, however, as it suggests a universal phonetics which is not evident across languages
[40]. Cross-linguistic patterns show that what can be treated as the same gestural units produce different contextualised patterns in different languages
[41]. Articulatory Phonology fails to attend to the acoustic output of the gestures themselves (meaning that many typological patterns remain unexplained)
[42]. Freedom among listeners in the weighting of perceptual cues in the acoustic signal has a more fundamental role to play in the emergence of structure
[43]. The realization of the perceptual contrasts by means of articulatory movements means that articulatory considerations do play a role
[44], but these are purely secondary.
In diachrony and synchrony
Several mathematical models of language change rely on self-organizing or dynamical systems. Abrams and Strogatz (2003)
[45][Full citation needed] produced a model of language change that focused on “
language death” - the process by which a speech community merges into the surrounding speech communities. Nakamura et al. (2008)
[46][Full citation needed] proposed a variant of this model that incorporates spatial dynamics into language contact transactions in order to describe the emergence of creoles. Both of these models proceed from the assumption that language change, like any self-organizing system, is a large-scale act or entity (in this case the creation or death of a language, or changes in its boundaries) that emerges from many actions on a micro-level. The microlevel in this example is the everyday production and comprehension of language by speakers in areas of language contact.
