. This is accomplished through the creation of subsystems in an effort to copy within a system the difference between it and the environment. The differentiation process is a means of increasing the complexity of a system, since each subsystem can make different connections with other subsystems. It allows for more variation within the system in order to respond to variation in the environment. Increased variation facilitated by differentiation not only allows for better responses to the environment, but also allows for faster evolution

 is the first major theorist who develops a theory of society consisting of functionally defined sub-system, which emerges from an evolutionary point of view through a cybernetic process of differentiation. Luhmann who studied under Talcott Parsons has adapted Parsons model although changed it in various directions. Parsons regard society was the combined activities of its subsystems within the logic of the cybernetic hierarchy. For Parsons each subsystem (of which his classical AGIL scheme or AGIL paradigm

 is divided into four) would tend to have self-referential tendencies and the related path of structural differentiation but it would occur in a constant interpenetrative communication with the other subsystems and the historical equilibrium between the interpenetrative balance between various subsystem would termine the relative degree in which the structural differentiation between subsystem would occur or not. In contrast to Luhmann, Parsons would highlight that although each subsystem had self-referential capacities and had an internal logic of this own (ultimately located in the pattern maintenance of each system) in historical reality, the actual interaction, communication and mutual enable-ness between the subsystem was crucial not only for each subsystem but for the overall development of the social system (and/or "society"). In actual history, Parsons maintained that the relative historical strength of various subsystems (including the interpenetrative equilibrium of each subsystem's subsystems) could either block or promote the forces of system-differentiation. Generally, Parsons was of the opinion that the main "gatekeeper" blocking-promoting question was to be found in the historical codificaction of the cultural system, including "cultural traditions" (which Parsons in general regarded as a part of the so-called "fiduciary system" (which facilitated the normatively defining epicenter of the communication and historical mode of institutionalization between cultural and social system). (For example, the various way Islam has been transferred as a cultural pattern into various social systems (Egypt, Iran, Tunisia, Yemen, Pakistan, Indonesia etc.) depend on the particular way in which the core Islamic value-symbols has been codified within each partiular fiduciary system (which again depend on a serie of various societal and history-related factors)). Within the realm of the cultural traditions Parsons focused particular on the influence of the major world-religions yet he also maintain that in the course of the general rationalization process of the world and the related secularization process, the value-scheme structure of the religious and "magic" systems would stepwise be "transformed" into political ideologies, market doctrines, folklore systems, social lifestyles and aesthetic movements (and so on). This transformation Parsons maintain was not so much the destruction of the religious value-schemes (although such a process could also occur) but was generally the way in which "religious" (and in a broader sense "constitutive") values would tend to move from a religious-magic and primodial "representation" to one which was more secularized and more "modern" in its institutionalized and symbolistic expression; this again would coincide with the increasing relative independence of systems of expressive symbolization vis-a-vis cognitive and evaluative lines of differentiation (for example, the flower-power movement in the 60s and early 70s would be a particular moment in this increased impact on factors of expressive symbolization on the overall interpenetrative mode of the social system. The breakthrough of rockmusic in the 1950s and the sensual expressiveness of Elvis would be another example, for the way in which expressive symbolization would tend to increase its impact vis-a-vis other factors of system-differentiation, which again according to Parsons was a part of the deeper evolutionary logic, which in part was related to the increased impact of the goal-attachment function of the cultural system and at the same time related the increased factor of institutionalized individualism, which have become a fundamental feature for historical modernity). Luhmann tend to claim that each subsystem has autopoeitic "drives" of their own. Instead of reducing society as a whole to one of its subsystems, i.e.; Karl Marx

, Luhmann bases his analysis on the idea that society is a self differentiating system that will, in order to attain mastery over an environment that is always more complex than it, increase its own complexity through a proliferating of subsystems. Although Luhamnn claim that society cannot be reduced to any one of its subsystems, this critics maintain that his autopoetic assumptions make it impossible to "constitute" a society at all and that Luhmann's theory is inherently self-contradictory. “Religion

There are four types of differentiation: segmentation, stratification, center-periphery, and functional.

Niklas Luhmann

Niklas Luhmann (December 8, 1927 - November 6, 1998) was a German sociologist and "social systems theorist", as well as one the most prominent modern day thinkers in the sociological systems theory. Luhmann was born in Lüneburg

, then the world's most influential social systems theorist. In later years, Luhmann dismissed Parsons' theory, developing a rival approach of his own. His magnum opus, Die Gesellschaft der Gesellschaft ("The Society of Society"), appeared in 1997 and has been subject to much review and critique since.

Segmentary differentiation

Segmentary differentiation divides parts of the system on the basis of the need to fulfill identical functions

 over and over. For instance, an automobile manufacturer has functionally similar factories for the production of cars at many different locations. Every location is organized in much the same way; each has the same structure and fulfills the same function – producing cars (Ritzer 2007:96).

Stratifactory differentiation

Stratificatory differentiation is a vertical differentiation according to rank or status

 is an accidental variance and serves no essential function, however, inequality is systemic in the function of stratified systems. A stratified system is more concerned with the higher ranks (president, manager) than it is with the lower ranks (assembly worker) with regard to "influential communication." However, the ranks are dependent on each other and the social system will collapse unless all ranks realize their functions. This type of system tends to necessitate the lower ranks to initiate conflict

 in order to shift the influential communication to their level. (Ritzer 2007:97).

Center-periphery differentiation

Center-periphery differentiation is a link between Segmentary and Stratificatory, an example is again, automobile firms, may have built factories in other countries, nevertheless the headquarters for the company remains the center ruling, and to whatever extent controlling, the peripheral factories (Ritzer 2007: 98).

Functional differentiation

Functional differentiation is the form that dominates modern society and is also the most complex form of differentiation. All functions within a system become ascribed to a particular unit
Unit
-Mathematics:* Unit , an element that is invertible with respect to ring multiplication* 1 , the unit number* Unit vector, a of the class of objects being studied-Science and technology:...

/location. Again, citing the automobile firm as an example, it may be "functionally differentiated" departmentally, having a production department, administration, accounting, planning, personnel, etc. Functional Differentiation tends to be more flexible than Stratifactory, but just as a stratified system is dependent on all rank, in a Functional system if one part fails to fulfill its task, the whole system will have great difficulty surviving. However, as long as each unit is able to fulfill its separate function, the differentiated units become largely independent; functionally differentiated systems are a complex mixture of interdependence
Interdependence
Interdependence is a relation between its members such that each is mutually dependent on the others. This concept differs from a simple dependence relation, which implies that one member of the relationship can function or survive apart from the other....

 and independence. E.g., the planning division may be dependent on the accounting division for economic data, but so long as the data is accurately compiled the planning division can be ignorant of the methodology involved to collect the data, interdependence yet independence (Ritzer 2007:98).

Code

Code is a way to distinguish elements within a system from those elements not belonging to that system. It is the basic language of a functional system. Examples are truth for the science system, payment for the economic system
Economic system
An economic system is the combination of the various agencies, entities that provide the economic structure that defines the social community. These agencies are joined by lines of trade and exchange along which goods, money etc. are continuously flowing. An example of such a system for a closed...

, legality for the legal system; its purpose is to limit the kinds of permissible communication. According to Luhmann a system will only understand and use its own code, and will not understand nor use the code of another system; there is no way to import the code of one system into another because the systems are closed and can only react to things within their environment (Ritzer 2007:100).

Understanding the risk of complexity

It is exemplified that in Segmentary differentiation if a segment fails to fulfill its function it does not affect or threaten the larger system. If an auto plant in Michigan stops production this does not threaten the overall system, or the plants in other locations. However, as complexity increases so does the risk of system breakdown. If a rank structure in a Stratified system fails, it threatens the system; a Center-Periphery system might be threatened if the control measure, or the Center/Headquarters failed; and in a Functionally differentiated system, due to the existence of interdependence despite independence the failure of one unit will cause a problem for the social system, possibly leading to its breakdown. The growth of complexity increases the abilities of a system to deal with its environment, but complexity increases the risk of system breakdown. It is important to note that more complex systems do not necessarily exclude less complex systems, in some instances the more complex system may require the existence of the less complex system to function (Ritzer 2007:98-100).

Differentiation and modern social theory

Luhmann uses the operative distinction between system and environment to determine that society is a complex system which replicates the system/environment distinction to form internal subsystems. Science is among these internally differentiated social systems, and within this system is the sub-system sociology. Here, in the system sociology, Luhmann finds himself again, an observer

 observing society. His knowledge of society as an internally differentiated system is a contingent observation made from within one of the specialized function-systems he observes. He concludes, therefore, that any social theory claiming universal status must take this contingency into account. Once one uses the basic system/environment distinction, then none of the traditional philosophical or sociological distinctions – transcendental

Differentiation: Luhmann's critique of Grand Theory

Luhmann felt that the society that thematized itself as political society misunderstood itself. It was simply a social system in which a newly differentiated political subsystem had functional primacy. Luhmann analyzes the Marxist approach to an economy based society: In this theory, the concept of economic society is understood to denote a new type of society in which production

", of taking the part for the whole, which in this context means identifying a social subsystem with the whole of society. The error can be traced to the dramatic nature of the emergence of each subsystem and its functional primacy (for a time) in relation to the other spheres of society. Nevertheless, the functional primacy claimed for the economy should not have led to asserting an economic permeation of all spheres of life. The notion of the economy possessing functional primacy is compatible with the well-known circumstance that the political subsystem not only grew increasingly differentiated (from religion
