"In the modern systems approach, the concept "system" is used not to refer to things in the world but to a particular way of organising our thoughts about the world."
"If Critical Systems Thinking is to contribute to enlightened societal practice, e.g., with respect to the pressing environmental and social issues of our time, it should be accessible not only to well-trained decision makers and academics but also to a majority of citizens."
"The classification of a system as complex or simple will depend upon the observer of the system and upon the purpose he has for considering the system."
"Operational research OR is regarded by many as being in crisis. If OR is taken to be ‘classical OR’, this is indisputable … If, however, the definition of OR is widened to embrace other systems-based methodologies for problem solving, then a diversity of approaches may herald not crisis, but increased competence and effectiveness in a variety of different problem contexts."
"The traditional, scientific method for studying such systems is known as reductionism. Reductionism sees the parts as paramount and seeks to identify the parts, understand the parts and work up from an understanding of the parts to an understanding of the whole. The problem with this is that the whole often seems to take on a form that is not recognizable from the parts. The whole emerges from the interactions between the parts, which affect each other through complex networks of relationships. Once it has emerged, it is the whole that seems to give meaning to the parts and their interactions. A living organism gives meaning to the heart, liver and lungs; a family to the roles of husband, wife, son, daughter"
"There exists an alternative to reductionism for studying systems. This alternative is known as holism. Holism considers systems to be more than the sum of their parts. It is of course interested in the parts and particularly the networks of relationships between the parts, but primarily in terms of how they give rise to and sustain in existence the new entity that is the whole whether it be a river system, an automobile, a philosophical system or a quality system."
"Different methodologies express different rationalities stemming from alternative theoretical positions which they reflect. These alternative positions must be respected, and methodologies and their appropriate theoretical underpinnings developed in partnership."
"The problem solver needs to stand back and examine problem contexts in the light of different “Ws” (weltanschauungen). Perhaps he can then decide which “W” seems to capture the essence of the particular problem context he is faced with. This whole process needs formalizing if it is to be carried out successfully. The problem solver needs to be aware of different paradigms in the social sciences, and he must be prepared to view the problem context through each of these paradigms."
"The classical Greek philosophers, Aristotle and Plato, established some important systems ideas. Aristotle reasoned that the parts of the body only make sense in terms of the way they function to support the whole organism and used this biological analogy to consider how individuals need to be related to the State. Plato was interested in how the notion of control, or the art of steersmanship (kybernetes), could be applied both to vessels and the State. Ships had to be steered safely toward harbour by a helmsman. A similar role needed to be followed in societies if they were to prosper."
"A.D. Hall's (1962) classic account of the methodology was based on his experience with the Bell Telephone Laboratories. Hall sees systems as existing in hierarchies. In systems engineering, plans to achieve a general objective must similarly be arranged in a hierarchy, with the systems engineer ensuring the internal consistency and integration of the plans, The methodology itself ensures the optimization of the system of concern with respect to its objectives. This requires a number of steps, the most important being problem definition, choosing objectives, systems synthesis, systems analysis, systems selection, system development, and current engineering. With Hall, the system of concern is usually a physical entity."
"We consider the notion of "system" as an organising concept, before going on to look in detail at various systemic metaphors that may be used as a basis for structuring thinking about organisations and problem situations."
"In the most abstract sense, a system is a set of objects together with relationships among the objects. Such a definition implies that a system has properties, functions, and dynamics distinct from its constituent objects and relationships."
"# Emergent structuring, whereby participants discover or adopt certain similar strategies within bounded rationality and situations with certain opportunity structures and incentive structures. Social network and ecological properties result in relatively well-defined aggregate performance characteristics..."
"Within sociology there have been several system theories, differing from one another in the extent to which, for example, human agency, creativity, and entrepreneurship are assumed to play a role in system formation and reformation; conflict and struggle are taken into account; power and stratification are part and parcel of the theory; structural change and transformation – and more generally, historically developments – are taken into account and explained. What the various system theories have in common is a systematic concern with complex and varied interconnections and interdependencies of social life. Complexity has been a central concept for many working in the systems perspective. The tradition is characterized to a great extent by a burning ambition and hope to provide a unifying language and conceptual framework for all the social sciences."
"As an intellectual enterprise, what came to be called ‘‘modernization theory’’ has many of the same positivist traits as Marxism, with which it self-consciously draws a comparison. Indeed, it could be argued that both constitute a form of ‘‘high modernism’’ that emphasize, in a deterministic form, the unity of all modern development, centered on industry and technology. The Harvard sociologist Talcott Parsons, whose 1937 book The Structure of Social Action inspired most of the postwar modernization theorists, had claimed that an integrated and stable transition to industrial society could only be achieved through changes in political and cultural values. But, unlike Marx, Parsons believed that it was the opportunities for the individual to fit into the structures of society that determined the course of history, not economic developments alone. For Parsons, for MIT’s Daniel Lerner, and for Walt Whitman Rostow – the Harvard professor whose 1960 The Stages of Economic Growth: A Non-Communist Manifesto later became a key text for modernization theory – the form of transition that they described had already taken place, in America. But there were enough ‘‘unsuccessful modernizations’’ – Germany, the Soviet Union, China – to necessitate the search for a grand theory of the road from ‘‘tradition’’ to ‘‘modernity.’’"
"Parsons, who published his first synthesizing works in economics journals, had always seen himself as a synthesizer who might do for sociology what Samuelson did for economics. Why did he fail?Part of the problem was undoubtedly the mind-set of sociologists of his time (and ours), which was to attach political messages to rather pedestrian observational and statistical material, and to reject any notion that there might be a "general theory" of sociology. But part of the problem was also Parsons' failure to articulate the close affinities of biological and economic theory with sociology."
"In sum, social actors knowledgeably and actively use, interpret and implement rule systems. They also creatively reform and transform them. In such ways they bring about institutional innovation and transformation and shape the ‘deep structures’ of human history."
"Sociology did have a period of core theory consolidation, in the person of Talcott Parsons, whose contributions in the three decades starting in 1937 were systematically geared towards synthesizing the greats of traditional sociology (Max Weber, Emile Durkheim, and Vilfredo Pareto), as well as indicating precisely how the sister disciplines of psychology, economics, and political science might articulate with core sociological theory. There is no doubt but that Parsons' body of theory is seriously flawed, but there was much more than enough to build on in forging a core sociological theory. Parsons correctly started with the division of social life into roles occupied by actors who internalize the norms and values associated with these roles. However, he made the mistake of identifying the rational actor model of economic theory with Homo economicus, the socially isolated selfish material maximizer. It is true that this is how the rational actor model was depicted in economic theory, but only by happenstance, not intrinsic logicality. Extending the rational actor model to include moral elements as well as material elements, self-regard as well as other-regard, would have given Parsons exactly the tool he needed to create a core sociological theory. However, he did not take this step, probably because (a) Pareto had convinced him that the economics/sociology split was just the norms and values/material self-interest split, and (b) he was a poor mathematician can couldn't handle the sophistication of the rational actor model. So he moved on to structural-functionalism, which is useful and insightful, but quite incapable of supporting an analytically cogent sociology."
"My analysis of Parson's failure, however, was not the reaction of other leading sociologists of the time. Rather, Parsons was bitterly criticized and rejected whole cloth. The offenders---and I here choose my words carefully---were mostly crusading left-wing sociologists who considered sociology an instrument of social change first, and a science only second. They include Alvin Gouldner, Theda Skocpol, George Homans, Lewis Coser, Ralf Dahrendorf, C. Wright Mills, Tom Bottomore, and many others. These pseudo-theorists in fact had no idea what social theory should look like, and railed against Parsons because he did not directly deal with social oppression and his language was not inherently emancipatory. To my mind, this is like criticizing da Vinci's studies of human anatomy because they don't deal with cancer and the plague---infinitely shortsighted and even risible. Habermas and others criticized Parsons on the grounds that systems theory is inherently hostile to action theory. This too is just a terrible mistake, since Parsons' theory of action was from the very first a pillar of his social theory. And what have these critics given us in place of Parsons' core theory? Some entertaining stories and a little credible philosophy, but nothing in the form of social theory."
"The rule systems governing transactions among agents in a defined sphere specify, to a greater or lesser extent, who participates (and who is excluded), who does what, when, where and how, and in relation to whom. ln particular, they define possible rights and obligations, including rules of command and obedience, governing specified categories of actors or roles vis a vis one another. The theory deals with the properties of social rule systems, their role in patterning social life, and the social and political processes whereby such systems are produced, maintained, and transformed as well as implemented in social action and interaction."
"Culture has been distinguished from the other elements of action by the fact that it is intrinsically transmissible from one action system to another from personality to personality by learning and from social system to social system by diffusion. This is because culture is constituted by "ways of orienting and acting," these ways being "embodied in" meaningful symbols."
"I regarded (and regard) Parsons’s work as mostly quite empty of serious content."
"There are two basic ways market organization is brought about... Some combination of the two is usual the case:"
"System theories have been applied to a wide spectrum of empirical cases and policy issues. Parsons and his followers, in particular, applied their systems theory to diverse empirical phenomena in sociology as well as in other disciplines: modernization, economics, politics, social order, industrialization and development, Fascism and McCarthyism, international relations, social change and evolution, complex organizations, health care, universities, religion, professions, small groups, and family as well as abstract questions such as the place of norms in maintaining social order both historically and cross-nationally. Marxian theory and dynamic system theories have also been applied to a spectrum of diverse empirical and policy subjects."
"Theory in the social sciences should have three major functions. First, it should aid in the codification of our existing concrete knowledge. It can do so by providing generalized hypotheses for the systematic reformulation of existing facts and insights, by extending the range of implication of particular hypotheses, and by unifying discrete observations under general concepts. Through codification, general theory in the social sciences will help to promote the process of cumulative growth of our knowledge. In making us more aware of the interconnections among items of existing knowledge which are now available in a scattered, fragmentary form, it will help us fix our attention on the points where further work must be done. Second, general theory in the social sciences should be a guide to research. By codification it enables us to locate and define more precisely the boundaries of our knowledge and of our ignorance. Codification facilitates the selection of problems, although it is not, of course, the only useful technique for the selection of problems for fruitful research. Further than this, general theory should provide hypotheses to be applied and tested by the investigation of these problems... Third, general theory as a point of departure for specialized work in the social sciences will facilitate the control of the biases of observation and interpretation which are at present fostered by the departmentalization of education and research in the social sciences."
"Markets are social organizations, structured and regulated by more or less well-defined social rule systems."
"A social system consists in a plurality of individual actors interacting with each other in a situation which has at least a physical or environmental aspect, actors who are motivated in terms of a tendency to the "optimization of gratification" and whose relation to their situations, including each other, is defined and mediated in terms of a system of culturally structured and shared symbols."
"suggest that we think of theories as spotlight. this imagery is useful. a spotlight will only illuminate so much. with any theory there will always be the things that are left in darkness, still unexamined and unexplained. parsons referred to these as 'residual categories'."
"The most elementary communication is not possible without some degree of conformity to the “conventions” of the symbolic system."
"A theoretical system does not merely state facts which have been observed and that logically deducible relations to other facts which have also been observed. In so far as such a theory is empirically correct it will also tell us what empirical facts it should be possible to observe in a given set."
"As a formal analytical point of reference, primacy of orientation to the attainment of a specific goal is used as the defining characteristic of an organization which distinguishes it from other types of social systems."
"The structure of a theoretical system tells us what alternatives are open in the possible answers to a given question. If observed facts of undoubted accuracy will not fit any of the alternatives it leaves open, the system itself is in need of reconstruction."
"A social system is a mode of organization of action elements relative to the persistence or ordered processes of change of the interactive patterns of a plurality of individual actors."
"Without deliberate planning on anyone's part, there have developed in our type of social system, and correspondingly in others, mechanisms which, within limits, are capable of forestalling and reversing the deep-lying tendencies for deviance to get into the vicious circle phase which puts it beyond the control of ordinary approval-disapproval and reward-punishment sanctions."
"The functions of the family in a highly differentiated society are not to be interpreted as functions directly on behalf of the society, but on behalf of personality."
"Every social system is a functioning entity. That is, it is a system of interdependent structures and processes such that it tends to maintain a relative stability and distinctiveness of pattern and behavior as an entity by contrast with its - social or other - environment, and with it a relative independence from environmental forces. It "responds", to be sure, to the environmental stimuli, but is not completely assimilated to its environment, maintaining rather an element of distinctiveness in the face of variations in environmental conditions. To this extent it is analogous to an organism"
"The most promising lines of development of theory in the sociological and most immediately related fields, particularly the psychological and cultural, therefore, seem to be two-fold. One major direction is the theoretical elaboration and refinement of structural-functional analysis of social systems, including the relevant problems of motivation and their relation to cultural patterns. In this process, the structure of social action provides a basic frame of reference, and aspects of it become of direct substantive importance at many specific points. The main theoretical task, however, is more than a refinement of the conceptual scheme of the presently reprinted book — it involves transition and translation to a different level and focus of theoretical systematization."
"In recent decades, conceptual approaches have been developed which attempt to solve the structure-agency dilemma (e.g. Giddens, 1984; Bourdieu, 1977; Burns and Flam, 1987). In these approaches, actors are seen as embedded in wider structures, which configure their preferences, aims, strategies. Despite these structuring effects, the approaches leave much room to actors and agency, i.e. conscious and strategic actions. Giddens, for instance, talks of the ‘duality of structure’, where structures are both the product and medium of action. Bourdieu coined terms such as ‘habitus’ and ‘field’ to conceptualise similar notions. And Burns and Flam developed a ‘social rule system theory’ to understand dynamic relationships between actors and structure."
"Among other related major developments, world systems theory (Wallerstein 2004) should be mentioned. Inspired by Marxist theories, it addresses dependency among nations and imperialism, placing the evolution of capitalist systems in a global and comparative perspective. Another variant of Marxist system theory is that of Pierre Bourdieu (1977) which unifies the material and the symbolic, as well as agency and structure."
"The social system is, thus, a very complex entity. As an organization of human interests, activities and commitments, it must be viewed as a system and in functional perspective. This is the key to its lines of organization, its modes of differentiation, and its integration. Such a system may be considered as both structure and process, in different aspects and for different scientific purposes. Structurally, we have suggested that there is a double basis for systematizing differentiation and variation : that internal to the primary social system itself and that involved in its relations to its primary environments, as analyzed with reference to the general system of action. Processually, the categories of analysis must follow from and integrate with those of structure. I suggest that, given the central position language as definitive of human society, the more differentiated and specialized symbolic media of interchange constitute the master scheme for the systematic analysis of social system processes."
"Actor-oriented, dynamic systems theories. This family of theories -- inspired to a great extent by Buckley -- is largely non-functionalist. It includes Buckley’s (1967, 1998) “modern systems theory,” Archer’s (1995) “morphogenetic” theory, Burns’ “actor-system-dynamics” (also ASD; Burns et al. 1985; Burns and Flam 1987), and the “” of Geyer and van der Zouwen (1978). Complex, dynamic social systems are analysed in terms of stabilizing and destabilizing mechanisms, with human agents playing strategic roles in these processes. Institutions and cultural formations of society are carried by, transmitted, and reformed through individual and collective actions and interactions."
"# Strategic structuring, informal or formal, whereby social agents, including the state, establish a rule regime regulating market access and transactions..."
"Talcott Parsons, the "incurable theorist" in his own words,... brought together, in a systematic and generalized form, the main outlines of a conceptual scheme of social action and social systems (e.g. 1951). His frame of reference focused on the description of the system of institutionalized roles, motivational process, economic exchange, political power and other Issues that according to his view should be included in a general sociological theory."
"Functionalist systems theories. The theorists in this tradition explain the emergence and/or maintenance of parts, structures, institutions, norms or cultural patterns of a social system in terms of their consequences, that is, the particular functions each realizes or satisfies. This includes, for instance, their contribution to the maintenance and reproduction over time of the larger system. The major functionalist in sociology is arguably Talcott Parsons."
"In a sense the present work is to be regarded as a secondary-study of the work of a group of writers in the field of social theory. But the genus "secondary study" comprises several species; of these an example of only one, and that perhaps not the best known, is to be found in these pages."
"'System' is the concept that refers both to a complex of interdependencies between parts, components, and processes, that involves discernible regularities of relationships, and to a similar type of interdependency between such a complex and its surrounding environment."
"Ideology is a system of beliefs, held in common by the members of a collectivity."
"Historical, political economic systems theory. The Marxian approach to system theorizing clearly points us to sociologically important phenomena: the material conditions of social life, stratification and social class, conflict, the reproduction as well as transformation of capitalist systems, the conditions that affect group mobilization and political power, and the ways ideas functions as ideologies."
