The Origins of Order: Self-organization and Selection in Evolution
The origins of life: a new view; 8. The origin of a connected metabolism; 9. Autocatalytic polynucleotide systems: hypercycles, spin glasses and coding; The architecture of genetic regulatory circuits and its evolution; Differentiation: the dynamical behaviors of genetic regulatory networks; Selection for gene expression in cell type; If one asks why there is and ought to be a science of biology a proper answer has to be derived from the empirically discernible differences between systems classified as living and those considered nonliving.
Granted that historically the line of demarcation between living and nonliving things has shifted flowing water, for instance, was once considered living , the distinction as drawn in the present era neatly differentiates between self-maintaining and self-reproducing material systems as living and all others as nonliving. The commonly accepted view is that this distinction is not due to some nonphysical forces acting in the living systems, although this is an empirical question.
Instead, it seems that living things owe their status to the peculiar spatiotemporal organization of quite ordinary physicochemical processes. Consequently, biology is the science of the organizational principles that make living things living. Kauffman's book is a massive attempt to provide the foundations of a theory of such organization. The big triumph of lateth-- and earlyth--century biology was the discovery of natural selection, that is, of a mechanism able to explain the origin of order in the living world. This discovery together with cell biology and genetics is the basis for the unity of biological sciences.
What is to be learned from further exploration of the origins of order? 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. Nyquist stability criterion. Warren McCulloch proposed "Redundancy of Potential Command"  as characteristic of the organization of the brain and human nervous system and the necessary condition for self-organization. In the s 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.
In the s 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"  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.
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. Examples such as critical mass , herd behaviour , groupthink and others, abound in sociology , economics , behavioral finance and anthropology. In social theory, the concept of self-referentiality has been introduced as a sociological application of self-organization theory by Niklas Luhmann For Luhmann the elements of a social system are self-producing communications, i.
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.
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". 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. Enabling others to "learn how to learn"  is often taken to mean instructing them  how to submit to being taught. Self-organised learning S. 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.
In — these complex self-organizing effects were explained by Boris Kerner 's three-phase traffic theory. Order appears spontaneously in the evolution of language as individual and population behaviour interacts with biological evolution. 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. Most scientists would agree with the critical view expressed in Problems of Biological Physics Springer Verlag, by the biophysicist L.
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.
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. 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.
In theology , Thomas Aquinas — 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: . 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.
