Self-organization, also called spontaneous order in the social sciences, is a process where some form of overall order arises from local interactions between parts of an initially disordered system. The process can be spontaneous when sufficient energy is available, not needing control by any external agent. It is often triggered by seemingly random fluctuations, amplified by positive feedback. The resulting organization is wholly decentralized, distributed over all the components of the system. As such, the organization is typically robust and able to survive or self-repair substantial perturbation. Chaos theory discusses self-organization in terms of islands of predictability in a sea of chaotic unpredictability.

Self-organization occurs in many physical, chemical, biological, robotic, and cognitive systems. Examples of self-organization include crystallization, thermal convection of fluids, chemical oscillation, animal swarming, neural circuits, and black markets.

Overview

Self-organization is realizedGlansdorff, P., Prigogine, I. (1971).

The concept has proven useful in biology, from the molecular to the ecosystem level.Compare: {{cite book| last1=Camazine| first1=Scott| title=Self-organization in Biological Systems| url= https://books.google.com/books?id=zMgyNN6Ufj0C |series= Princeton studies in complexity| edition= reprint| publisher=Princeton University Press| publication-date=2003| isbn=978-0-691-11624-2| access-date= 2016-04-05| year=2003}} Cited examples of self-organizing behavior also appear in the literature of many other disciplines, both in the natural sciences and in the social sciences (such as economics or anthropology).

Principles

The cybernetician William Ross Ashby formulated the original principle of self-organization in 1947.{{Cite journal | doi=10.1080/00221309.1947.9918144| pmid=20270223| title=Principles of the Self-Organizing Dynamic System| journal=The Journal of General Psychology| volume=37| issue=2| pages=125–28| year=1947| last1=Ashby | first1=W. R.}}Ashby, W. R. (1962). [http://csis.pace.edu/~marchese/CS396x/Computing/Ashby.pdf "Principles of the self-organizing system"], pp. 255–78 in Principles of Self-Organization. Heinz von Foerster and George W. Zopf, Jr. (eds.) U.S. Office of Naval Research. It states that any deterministic dynamic system automatically evolves towards a state of equilibrium that can be described in terms of an attractor in a basin of surrounding states. Once there, the further evolution of the system is constrained to remain in the attractor. This constraint implies a form of mutual dependency or coordination between its constituent components or subsystems. In Ashby's terms, each subsystem has adapted to the environment formed by all other subsystems.

The cybernetician Heinz von Foerster formulated the principle of "order from noise" in 1960.Von Foerster, H. (1960). [http://e1020.pbworks.com/f/fulltext.pdf "On self-organizing systems and their environments"], pp. 31–50 in Self-organizing systems. M.C. Yovits and S. Cameron (eds.), Pergamon Press, London It notes that self-organization is facilitated by random perturbations ("noise") that let the system explore a variety of states in its state space. This increases the chance that the system will arrive into the basin of a "strong" or "deep" attractor, from which it then quickly enters the attractor itself. The biophysicist Henri Atlan developed this concept by proposing the principle of "complexity from noise"See [https://www.google.com/search?&tbm=bks&q=inauthor:%22Henri+Atlan%22%22complexity+from+noise%22 occurrences] on Google Books.{{cite book |editor-last=François |editor-first=Charles |editor-link=Charles François (systems scientist) |title=International Encyclopedia of Systems and Cybernetics |year=2011 |orig-date=1997 |edition=2nd |publisher=Walter de Gruyter |location=Berlin |page=[https://books.google.com/books?id=XCn2mn98uEAC&dq=%22complexity+from+noise+principle%22+Atlan+1972&pg=PA107 107] |isbn=978-3-11-096801-9 |title-link=International Encyclopedia of Systems and Cybernetics }} ({{langx|fr|le principe de complexité par le bruit}})See [https://www.google.com/search?&tbm=bks&q=inauthor:%22Henri+Atlan%22%22complexité+par+le+bruit%22 occurrences] on Google Books. first in the 1972 book L'organisation biologique et la théorie de l'information and then in the 1979 book Entre le cristal et la fumée.

History

The idea that the dynamics of a system can lead to an increase in its organization has a long history. The ancient atomists such as Democritus and Lucretius believed that a designing intelligence is unnecessary to create order in nature, arguing that given enough time and space and matter, order emerges by itself.{{cite book |last1 =Palmer |first1= Ada |author-link1= Ada Palmer |title= Reading Lucretius in the Renaissance |date= October 2014|publisher= Harvard University Press |isbn= 978-0-674-72557-7|quote= Ada Palmer explores how Renaissance readers, such as Machiavelli, Pomponio Leto, and Montaigne, actually ingested and disseminated Lucretius, ... and shows how ideas of emergent order and natural selection, so critical to our current thinking, became embedded in Europe’s intellectual landscape before the seventeenth century. |url= http://www.hup.harvard.edu/catalog.php?isbn=978-0-674-72557-7}}

The philosopher René Descartes presents self-organization hypothetically in the fifth part of his 1637 Discourse on Method. He elaborated on the idea in his unpublished work The World.{{efn|For related history, see Aram Vartanian, Diderot and Descartes.}}

Immanuel Kant used the term "self-organizing" in his 1790 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.{{cite book|title= German Aesthetic|url= https://books.google.com/books?id=eC88AAAAIAAJ&pg=PA64|publisher= CUP Archive|pages= 64–|id= GGKEY:TFTHBB91ZH2}}

{{blockquote|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.}}

Sadi Carnot (1796–1832) and Rudolf Clausius (1822–1888) discovered the second law of thermodynamics in the 19th century. It states that total entropy, sometimes understood as disorder, will always increase over time in an isolated system. This means that a system cannot spontaneously increase its order without an external relationship that decreases order elsewhere in the system (e.g. through consuming the low-entropy energy of a battery and diffusing high-entropy heat).Carnot, S. (1824/1986).

18th-century thinkers had sought to understand the "universal laws of form" to explain the observed forms of living organisms. This idea became associated with Lamarckism and fell into disrepute until the early 20th century, when D'Arcy Wentworth Thompson (1860–1948) attempted to revive it.{{cite book |author1= Ruse, Michael |editor1-last= Henning |editor1-first= Brian G. |editor2-last= Scarfe |editor2-first= Adam |title= Beyond Mechanism: Putting Life Back Into Biology |date= 2013 |publisher= Lexington Books |page= 419 |url= https://books.google.com/books?id=3VtosxAtq-EC|chapter= 17.

The psychiatrist and engineer W. Ross Ashby introduced the term "self-organizing" to contemporary science in 1947. It was taken up by the cyberneticians Heinz von Foerster, Gordon Pask, Stafford Beer; and von Foerster organized a conference on "The Principles of Self-Organization" at the University of Illinois' Allerton Park in June, 1960 which led to a series of conferences on Self-Organizing Systems.Asaro, P. (2007). [http://peterasaro.org/writing/Asaro%20HVF%26BCL.pdf "Heinz von Foerster and the Bio-Computing Movements of the 1960s"] in Albert Müller and Karl H. Müller (eds.) An Unfinished Revolution? Heinz von Foerster and the Biological Computer Laboratory BCL 1958–1976. Vienna, Austria: Edition Echoraum. Norbert Wiener took up the idea in the second edition of his Cybernetics: or Control and Communication in the Animal and the Machine (1961).

Self-organization was associated{{by whom|date=May 2018}} with general systems theory in the 1960s, but did not become commonplace in the scientific literature until physicists Hermann Haken et al. and complex systems researchers adopted it in a greater picture from cosmology Erich Jantsch,{{clarify|date=May 2018}} chemistry with dissipative system, biology and sociology as autopoiesis to system thinking in the following 1980s (Santa Fe Institute) and 1990s (complex adaptive system), until our days with the disruptive emerging technologies profounded by a rhizomatic network theory.

As an indication of the increasing importance of this concept, when queried with the keyword self-organ*, Dissertation Abstracts finds nothing before 1954, and only four entries before 1970. There were 17 in the years 1971–1980; 126 in 1981–1990; and 593 in 1991–2000.

Around 2008–2009, a concept of guided self-organization started to take shape. This approach aims to regulate self-organization for specific purposes, so that a dynamical system may reach specific attractors or outcomes. The regulation constrains a self-organizing process within a complex system by restricting local interactions between the system components, rather than following an explicit control mechanism or a global design blueprint. The desired outcomes, such as increases in the resultant internal structure and/or functionality, are achieved by combining task-independent global objectives with task-dependent constraints on local interactions.Phys.org, [https://phys.org/news/2014-02-self-organizing-robots-robotic-crew-foreman.html Self-organizing robots: Robotic construction crew needs no foreman (w/ video)], February 13, 2014.Science Daily, [https://www.sciencedaily.com/releases/2015/10/151027123342.htm Robotic systems: How sensorimotor intelligence may develop... self-organized behaviors ], October 27, 2015.

The mathematical biologist Stuart Kauffman and other structuralists have suggested that self-organization may play roles alongside natural selection in three areas of evolutionary biology, namely population dynamics, molecular evolution, and morphogenesis. However, this does not take into account the essential role of energy in driving biochemical reactions in cells. The systems of reactions in any cell are self-catalyzing, but not simply self-organizing, as they are thermodynamically open systems relying on a continuous input of energy.{{cite journal |last1=Fox |first1=Ronald F. |title=Review of Stuart Kauffman, The Origins of Order: Self-Organization and Selection in Evolution |journal=Biophys.

The evolution of order in living systems and the generation of order in certain non-living systems was proposed to obey a common fundamental principal called “the Darwinian dynamic”Bernstein H, Byerly HC, Hopf FA, Michod RA, Vemulapalli GK. (1983) The Darwinian Dynamic. Quarterly Review of Biology 58, 185–207. {{JSTOR|2828805}} that was formulated by first considering how microscopic order is generated in simple non-biological systems that are far from thermodynamic equilibrium. Consideration was then extended to short, replicating RNA molecules assumed to be similar to the earliest forms of life in the RNA world. It was shown that the underlying order-generating processes of self-organization in the non-biological systems and in replicating RNA are basically similar.

=Cosmology=

In his 1995 conference paper "Cosmology as a problem in critical phenomena" Lee Smolin said that several cosmological objects or phenomena, such as spiral galaxies, galaxy formation processes in general, early structure formation, quantum gravity and the large scale structure of the universe might be the result of or have involved certain degree of self-organization.{{cite conference |last1=Smollin |first1=Lee |title=Cosmology as a problem in critical phenomena |book-title=Complex Systems and Binary Networks: Guanajuato Lectures Held at Guanajuato, México 16–22 January 1995 |editor=Ramón López-Peña |editor2=Henri Waelbroeck |editor3=Riccardo Capovilla |editor4=Ricardo García-Pelayo |editor5=Federico Zertuche |date=1995 |volume=461-461 |doi=10.1007/BFb0103573 |arxiv=gr-qc/9505022}} He argues that self-organized systems are often critical systems, with structure spreading out in space and time over every available scale, as shown for example by Per Bak and his collaborators. Therefore, because the distribution of matter in the universe is more or less scale invariant over many orders of magnitude, ideas and strategies developed in the study of self-organized systems could be helpful in tackling certain unsolved problems in cosmology and astrophysics.

=Computer science=

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.

=Cybernetics=

Norbert Wiener regarded the automatic serial identification of a black box and its subsequent reproduction as self-organization in cybernetics.Wiener, Norbert (1962) "The mathematics of self-organizing systems". Recent developments in information and decision processes, Macmillan, N.Y. and Chapter X in Cybernetics, or control and communication in the animal and the machine, The MIT Press. The importance of phase locking or the "attraction of frequencies", as he called it, is discussed in the 2nd edition of his Cybernetics: Or Control and Communication in the Animal and the Machine.Cybernetics, or control and communication in the animal and the machine, The MIT Press, Cambridge, Massachusetts and Wiley, NY, 1948. 2nd Edition 1962 "Chapter X "Brain Waves and Self-Organizing Systems" pp. 201–02. K. Eric 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.Ashby, William Ross (1952) Design for a Brain, Chapter 5 Chapman & Hall Ashby used his state counting measure of varietyAshby, William Ross (1956) [http://pespmc1.vub.ac.be/books/introcyb.pdf An Introduction to Cybernetics], Part Two Chapman & Hall to describe stable states and produced the "Good Regulator"{{cite journal|title=Every good regulator of a system must be a model of that system |author=Conant, R.

Warren McCulloch proposed "Redundancy of Potential Command"Embodiments of Mind MIT Press (1965)" 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/H_max, where H is entropy.{{cite journal|author=von Foerster, Heinz |author2= Pask, Gordon |title=A Predictive Model for Self-Organizing Systems, Part I|journal=Cybernetica|volume= 3|pages= 258–300|year=1961}}{{cite journal|author=von Foerster, Heinz |author2= Pask, Gordon |title=A Predictive Model for Self-Organizing Systems, Part II|journal=Cybernetica|volume= 4 |pages=20–55|year= 1961}} In essence this states that unused potential communication bandwidth is a measure of self-organization.

In the 1970s Stafford Beer considered self-organization necessary for autonomy in persisting and living systems. He applied his viable system model to management. It consists of five parts: the monitoring of performance 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 alerting "algedonic loop" feedback: a sensitivity to both pain and pleasure produced from under-performance or over-performance relative to a standard capability."Brain of the Firm" Alan Lane (1972); see also Viable System Model in "Beyond Dispute", and Stafford Beer (1994) "Redundancy of Potential Command" pp. 157–58.

In the 1990s Gordon Pask argued that von Foerster's H and Hmax were not independent, but interacted via countably infinite recursive concurrent spin processes which he called concepts. His strict definition of concept "a procedure to bring about a relation" permitted his theorem "Like concepts repel, unlike concepts attract"{{Cite journal | doi=10.1108/03684920110391913| title=On Gordon Pask| journal=Kybernetes| volume=30| issue=5/6| pages=673–82| year=2001| last1=Green | first1=N. }} to state a general spin-based principle of self-organization. His edict, an exclusion principle, "There are No Doppelgangers" means no two concepts can be the same. After sufficient time, all concepts attract and coalesce as pink noise. The theory applies to all organizationally closed or homeostatic processes that produce enduring and coherent products which evolve, learn and adapt.Pask, Gordon (1993) [http://www.cybsoc.org/PasksIAT.PDF Interactions of Actors (IA), Theory and Some Applications] {{Webarchive|url=https://web.archive.org/web/20040607170929/http://www.cybsoc.org/PasksIAT.PDF |date=June 7, 2004 }}.{{cite journal |author=Pask, Gordon |year=1996 |url=http://www.cybsoc.org/GPprog.PDF |title=Heinz von Foerster's Self-Organization, the Progenitor of Conversation and Interaction Theories |journal= Systems Research |volume=13|issue= 3 |pages=349–62 |doi=10.1002/(sici)1099-1735(199609)13:3<349::aid-sres103>3.3.co;2-7}}

=Sociology=

File:CIA Map of International illegal drug connections.gif

The self-organizing behavior 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. Examples such as critical mass, herd behavior, groupthink and others, abound in sociology, economics, behavioral finance and anthropology.[http://cmol.nbi.dk/models/ Interactive models for self organization and biological systems] Center for Models of Life, Niels Bohr Institute, Denmark

Spontaneous order can be influenced by arousal.{{Cite journal|url=http://www.jstor.org/stable/201903|title=Emergence, Self-Organization, and Social Interaction: Arousal-Dependent Structure in Social Systems|author1=Smith, Thomas S.|author2=Stevens, Gregory T.|year=1996|journal=Sociological Theory|volume=14|issue=2|pages=131–153|doi=10.2307/201903|jstor=201903 }}

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. Luhmann developed an evolutionary theory of society and its subsystems, using functional analyses and systems theory.Luhmann, Niklas (1995) Social Systems. Stanford, California: Stanford University Press. {{ISBN|0-8047-2625-6}}

=Economics=

The 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.Krugman, P. (1995) The Self Organizing Economy. Blackwell Publishers. {{ISBN|1-55786-699-6}} Friedrich Hayek coined the term catallaxyHayek, F. (1976) Law, Legislation and Liberty, Volume 2: The Mirage of Social Justice. University of Chicago Press. to describe a "self-organizing system of voluntary co-operation", in regards to the spontaneous order of the free market economy. Neo-classical economists hold that imposing central planning usually makes the self-organized economic system less efficient. On the other end of the spectrum, economists consider that market failures are so significant that self-organization produces bad results and that the state should direct production and pricing. Most 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.{{Cite journal| author=Biel, R. |author2=Mu-Jeong Kho |url=http://rechercheregulation.files.wordpress.com/2013/01/rr_working_serieid_2009-1.pdf |title=The Issue of Energy within a Dialectical Approach to the Regulationist Problematique |journal=Recherches & Régulation Working Papers, RR Série ID 2009-1 |pages=1–21 |publisher=Association Recherche & Régulation |date=November 2009 |access-date=2013-11-09}}Marshall, A.

=Transportation=

The self-organizing behavior of drivers in traffic flow determines almost all the spatiotemporal behavior of traffic, such as traffic breakdown at a highway bottleneck, highway capacity, and the emergence of moving traffic jams. These self-organizing effects are explained by Boris Kerner's three-phase traffic theory.{{cite journal | last1 = Kerner | first1 = Boris S. | year = 1998 | title = Experimental Features of Self-Organization in Traffic Flow | journal = Physical Review Letters | volume = 81| issue = 17 | pages = 3797–3800| doi=10.1103/physrevlett.81.3797 | bibcode=1998PhRvL..81.3797K}}

=Research=

Self-organized funding allocation (SOFA) is a method of distributing funding for scientific research. In this system, each researcher is allocated an equal amount of funding, and is required to anonymously allocate a fraction of their funds to the research of others. Proponents of SOFA argue that it would result in similar distribution of funding as the present grant system, but with less overhead.{{cite journal |last1=Bollen |first1=Johan |title=Who would you share your funding with? |journal=Nature |date=8 August 2018 |volume=560 |issue=7717 |pages=143 |doi=10.1038/d41586-018-05887-3 |pmid=30089925 |language=EN|bibcode=2018Natur.560..143B |doi-access=free }} In 2016, a test pilot of SOFA began in the Netherlands.{{cite web |last1=Coelho |first1=Andre |title=Netherlands: A radical new way do fund science {{!}} BIEN |date=May 16, 2017 |url=https://basicincome.org/news/2017/05/netherlands-radical-new-way-fund-science/ |access-date=2 June 2019}}

Criticism

Heinz Pagels, in a 1985 review of Ilya Prigogine and Isabelle Stengers's book Order Out of Chaos in Physics Today, appeals to authority:{{cite journal|url=http://www.fefox.com/ARTICLES/Pagels-PrigogineinPhysicsToday1985.pdf|author=Pagels, H. R. |title=Is the irreversibility we see a fundamental property of nature?|journal=Physics Today|volume=38 |issue=1 |date=January 1, 1985|pages=97–99|doi=10.1063/1.2813716|bibcode=1985PhT....38a..97P}}

{{blockquote|Most scientists would agree with the critical view expressed in Problems of Biological Physics (Springer Verlag, 1981) by the biophysicist L. A. Blumenfeld, when he wrote: "The meaningful macroscopic ordering of biological structure does not arise due to the increase of certain parameters or a system above their critical values. These structures are built according to program-like complicated architectural structures, the meaningful information created during many billions of years of chemical and biological evolution being used." Life is a consequence of microscopic, not macroscopic, organization.}}

Of course, Blumenfeld does not answer the further question of how those program-like structures emerge in the first place. His explanation leads directly to infinite regress.

{{blockquote|In short, they [Prigogine and Stengers] maintain that time irreversibility is not derived from a time-independent microworld, but is itself fundamental. The virtue of their idea is that it resolves what they perceive as a "clash of doctrines" about the nature of time in physics. Most physicists would agree that there is neither empirical evidence to support their view, nor is there a mathematical necessity for it. There is no "clash of doctrines." Only Prigogine and a few colleagues hold to these speculations which, in spite of their efforts, continue to live in the twilight zone of scientific credibility.}}

In theology, Thomas Aquinas (1225–1274) in his Summa Theologica assumes a teleological created universe in rejecting the idea that something can be a self-sufficient cause of its own organization:[http://www.newadvent.org/summa/1002.htm#article3 Article 3. Whether God exists?] newadvent.org

{{blockquote|Since nature works for a determinate end under the direction of a higher agent, whatever is done by nature must needs be traced back to God, as to its first cause. So also whatever is done voluntarily must also be traced back to some higher cause other than human reason or will, since these can change or fail; for all things that are changeable and capable of defect must be traced back to an immovable and self-necessary first principle, as was shown in the body of the Article.}}
