"Systems theory provides:"
"# A common vocabulary unifying the several "behavioral" disciplines."
"# A technique for treating large, complex organizations;"
"# A synthetic approach where piecemeal analysis is not possible due to the intricate interrelationships of parts that cannot be treated out of context of the whole;"
"# A viewpoint that gets at the heart of sociology because it sees the sociocultural system in terms of information and communication nets;"
"# The study of relations rather than "entities" with an emphasis on process and transition probabilities as the basis of a flexible structure of many degrees of freedom."
"# "An operationally definable, objective, non-anthropomorphic study of purposiveness, goal-seeking system behavior, symbolic cognitive processes, consciousness and self-awareness, and sociocultural emergence and dynamics in general."
"Of the so-called global theories the one initially stated and defined by Bertalanffy in 1947 under the title of "general systems theory" has taken hold... Since then he has refined, modified and applied his concepts, established a society for general systems theory and published a General Systems Yearbook. Many social scientists but only a handful of psychiatrists studied, understood or applied systems theory. Suddenly, under the leadership of Dr. William Gray of Boston, a threshold was reached so that at the 122nd annual meeting of the American Psychiatric Association in 1966 two sessions were held at which this theory was discussed and regular meetings for psychiatrists were ensured for future participation in and development of this "Unified Theory of Human Behavior." If there be a third revolution (i.e. after the psychoanalytic and behavioristic), it is in the development of a general theory."
"It is sheer nonsense to expect that any human being has yet been able to attain such insight into the problems of society that he can really identify the central problems and determine how they should be solved. The systems in which we live are far too complicated as yet for our intellectual powers and technology to understand."
"A great many writers have manifestly believed that there is a way of considering phenomena which is sufficiently different from the well-established modes of scientific analysis to deserve the particular title of systems thinking."
"The basic managerial idea introduced by systems thinking, is that to manage a system effectively, you might focus on the interactions of the parts rather than their behavior taken separately."
"General systems theory is the scientific exploration of "wholes" and "wholeness" which, not so long ago, were considered metaphysical notions transcending the boundaries of science. Hierarchic structure, stability, teleology, differentiation, approach to and maintenance of steady states, goal-directedness — these are a few of such general system properties."
"There has been an increased but still rather limited response to general systems theory, as variously reflected in the work of Bateson, Vayda, Rappaport, Adams, and an interest in the use of computers, programming, matrices, etc. But the interaction between general systems theory (as represented, for example, by the theoretical work of Von Bertalanffy) has been compromised, partly by the state of field data, extraordinarily incomparable as it inevitably is, as well as historical anthropological methods of dealing with wholes. General systems theory has taken its impetus from the excitement of discovering larger and larger contexts, on the one hand, and a kind of microprobing into fine detail within a system, on the other. Both of these activities are intrinsic to anthropology to the extent that field work in living societies has been the basic disciplinary method. It is no revelation to any field-experienced anthropologist that everything is related to everything else, or that whether the entire sociocultural setting can be studied in detail or not, it has to be known in general outline."
"What I consider completely sterile is the attitude, for instance, of Bertalanffy who is going around and jumping around for years saying that all the analytical science and molecular biology doesn’t really get to interesting results; let’s talk in terms of general systems theory … there cannot be anything such as general systems theory, it’s impossible. Or, if it existed, it would be meaningless."
"General systems theory deals with the most fundamental concepts and aspects of systems. Many theories dealing with more specific types of systems (e.g., dynamical systems, automata, control systems, game-theoretic systems, among many others) have been under development for quite some time. General systems theory is concerned with the basic issues common to all these specialized treatments."
"The Society for General Systems Theory and its publication General Systems was a mixed bag. Few authors were actually doing research -they philosophized, and many prematurely resolved dilemmas by mathematical equations in a language poorly understood by the empirical investigator."
"Systems theory is an attempt to provide a general explanation for social behaviour (certain types of this theory are referred to as grand theory)."
"Project management utilises the systems approach to management by having functional personnel (the vertical hierarchy) assigned to a specific project (the horizontal hierarchy)."
"General systems theory is considered as a formal theory (Mesarovic, Wymore), a methodology (Ashby, Klir), a way of thinking (Bertalanffy, Churchman), a way of looking at the world (Weinberg), a search for an optimal simplification (Ashby, Weinberg), didactic method (Boulding, Klir, Weinberg), metalanguage (Logren), and profession (Klir)."
"For a long time, people have been trying to characterize or define the notion of system. After all, “systems” are supposed to be what System Theory is about. The results so far have been contradictory and unsatisfactory. This confusion at the foundations has led many to conclude that there is no such thing as a "system" and hence to deny that System Theory is about anything. Even those most sympathetic to the notion have difficulties at this level. The very founders of System Theory did not try to say what a system was; and as for System Theory, they characterized it only obliquely, by saying it comprised all studies of interest to more than one discipline. They thereby begged the entire question."
"(Systems science) does not aim to find the one true representation for a given type of systems (e.g. physical, chemical or biological systems), but to formulate general principles about how different representations of different systems can be constructed so as to be effective in problem-solving."
"Systems inquiry has demonstrated its capability in dealing effectively with highly complex and large-scale problem situations. It has orchestrated the efforts of various disciplines within the framework of systems thinking. It has introduced systems approaches and methods to the analysis, design, development, evaluation, and management of systems of all kinds... Systems theory pursues the scientific exploration and understanding of systems that exist in the various realms of experience, in order to arrive at a general theory of systems: an organized expressing of sets of interrelated concepts and principles that apply to all systems."
"Critical systems thinking is a robust recent trend in humanistically oriented systems work. Spearheaded by work of Ulrich (1983), Flood (1990), and Flood and Jackson (1991), this approach manages to accommodate the knowledge-constitutive interests of Jürgen Habermas (1971) and the interpretive analytical orientations of Michel Foucault (1972) through a meta-methodology involving constant critical reflection. The meta-methodology serves as the basis for the generation of a new methodology that critically applies various systems approaches to problem solving."
"Systems science and technology constitute one aspect of systems thinking, but the humanities and arts make up the other. The fact that design plays such a large part in the systemic treatment of problems makes it apparent that art has a major role in it as well. Ethics and aesthetics are integral aspects of evaluating systems... the systems approach involves the pursuit of truth (science) and its effective use (technology), plenty (economics), the good (ethics and morality), and beauty and fun (aesthetics). To compare systems methodology with that of any of the so-called ‘hard’ disciplines—for example, physics—is to misunderstand the nature of systems. The worry is not that the systems approach is not scientific in the sense which physics or chemistry or biology is, but that some try to make it scientific in that sense. To the extent they succeed, they destroy it."
"Complexity theory is really a movement of the sciences. Standard sciences tend to see the world as mechanistic. That sort of science puts things under a finer and finer microscope. In biology the investigations go from classifying organisms to functions of organisms, then organs themselves, then cells, and then organelles, right down to protein and enzymes, metabolic pathways, and DNA. This is finer and finer reductionist thinking. The movement that started complexity looks in the other direction. It’s asking, how do things assemble themselves? How do patterns emerge from these interacting elements? Complexity is looking at interacting elements and asking how they form patterns and how the patterns unfold. It’s important to point out that the patterns may never be finished. They’re open-ended. In standard science this hit some things that most scientists have a negative reaction to. Science doesn’t like perpetual novelty."
"What is systems science? This question, which I have been asked on countless occasions, can basically be answered either in terms of activities associated with systems science or in terms of the domain of its inquiry. The most natural answers to the question are, almost inevitably, the following definitions:"
"# Systems science is what systems scientists do when they claim they do science."
"# Systems science is that field of scientific inquiry whose objects of study are systems."
"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."
"A system is a set of things — people, cells, molecules, or whatever — interconnected in such a way that they produce their own pattern of behavior over time... The system, to a large extent, causes its own behavior."
"Any virtue systematically applied becomes a vice. Morality is attention, not system."
"Societies grow into systems. The systems require management and are therefore increasingly wielded, like a tool or a weapon, by those who have power. The rest of the population is still needed to do specific things. But the citizens are not needed to contribute to the form or direction of the society. The more "advanced" the civilization, the more irrelevant the citizen becomes."
"A physical system is just that: a physical system. What is systematized is matter itself, and the processes in which the system is realized are also material. But a biological system is more complex: it is both biological and physical — it is matter with the added component of life; and a social system is more complex still: it is physical, and biological, with the added component of social order, or value. … A semiotic system is still one step further in complexity: it is physical, and biological, and social —and also semiotic: what is being systematized is meaning. In evolutionary terms, it is a system of the fourth order of complexity"
"A self–organizing system acts autonomously, as if the interconnecting components had a single mind. And as these components spontaneously march to the beat of their own drummer, they organize, adapt, and evolve toward a greater complexity than one would ever expect by just looking at the parts by themselves."
"No single human being could ever comprehend or acquire the full knowledge needed to mastermind all–encompassing events. This means that sociopolitical systems can never find the perfect leader or perfect management system to fine–tune society. The inherent nature of complexity is to doubt certainty and any pretense to finite and flawless data. Put another way, under uncertainty principles, any attempt by political systems to “impose order” has an equal chance to instead “impose disorder.”"
"Going into this system means you cannot be against it. It's good to keep a non-governmental free organisation without money from the government, and without having to play the political games. Just to be free and to have the possibility to discuss and control each decision of the from the streets... It's the best and most powerful place to be."
"The sun, as we have already said, is placed in the middle of our system, as a source of light and heat, to illuminate and vivify all the planets subordinate to it. Without his benign influence the earth would be a mere block, which in hardness would surpass marble and the most compact substances with which we are acquainted ; no vegetation, no motion would be possible: in a word, it would be the abode of darkness, inactivity and death. The first rank therefore among inanimate beings cannot be refused to the sun ; and if the error of addressing to a created object that adoration which is due to the Creator atone could admit of excuse, we might be tempted to excuse the homage paid to the sun by the ancient Persians, as is still the ease among the Guebres, their successors, and some savage tribes in America."
"We are raised to believe that breaking the law is wrong and following the law is right. But what if the law itself is a miscarriage of justice, crafted by those more interested in power and politics than in fairness? …do we have no choice but to adhere to a system that is proven to be unjust? Or do we have the right to object? … One of the greatest dangers of a system that we can observe, is that citizens come to accept the system's injustices as the norm. Over time, they begin to believe that only the state apparatus [and all those who enforce its written rules and unwritten rules] can implement justice, and that questioning or opposing the justice system makes them [and others] criminals or bad citizens [or bad people]."
"A system is only for the philosopher, for a system implies analysis, and the poetic method is essentially synthesis."
"A system is a body composed of two or more components or phases."
"A saint without a system is a fool, and a fool never yet convinced anybody..."
"When a system is radically wrong, we must abandon that system and find a better one."
"System is what differentiates the professional from the amateur."
"...those people who defend a nihilistic and ruthless system may go down with it as it implodes in on itself..."
"Systems... resemble the similar parts or muscles of a body natural. By systemes; I understand any numbers of men joyned in one Interest, or one Businesse. Of which, some are Regular, and some Irregular. Regular are those, where one Man, or Assembly of men, is constituted Representative of the whole number. All other are Irregular. Of Systemes subordinate, some are Politicall, and some Private. Politicall (otherwise Called Bodies Politique, and Persons In Law,) are those, which are made by authority from the Soveraign Power of the Common-wealth. Private, are those, which are constituted by Subjects amongst themselves, or by authoritie from a stranger. For no authority derived from forraign power, within the Dominion of another, is Publique there, but Private. And of Private Systemes, some are Lawfull; some Unlawfull: Lawfull, are those which are allowed by the Common-wealth: all other are Unlawfull. Irregular Systemes, are those which having no Representative, consist only in concourse of People; which if not forbidden by the Common-wealth, nor made on evill designe, (such as are conflux of People to markets, or shews, or any other harmelesse end,) are Lawfull. But when the Intention is evill, or (if the number be considerable) unknown, they are Unlawfull. ... And this is all I shall say concerning Systemes, and Assemblyes of People, which may be compared (as I said,) to the Similar parts of mans Body; such as be Lawfull, to the Muscles; such as are Unlawfull, to Wens, Biles, and Apostemes, engendred by the unnaturall conflux of evill humours."
"According to the common system, before the creation of Matter, there was nothing but God, whose essence is immutable, and cannot be the pre-existent subject of Bodies."
"In proportion, therefore, as a system is of vast extent and made for duration, the more it requires to be governed by a simple and general law. We have only to attend to the solar system, and we shall perceive the utility of a central body on which the whole depends. In virtue of this body, it rarely happens that the planets and comets disturb each other, and these extraordinary instances form but trifling exceptions. But were we to retrench the central body, the general law would be destroyed, and the exceptions alone would remain. Harmony, in that case, must be the result of an infinite combination, of individual and discordant impulsions; insomuch, that the more our view of the whole became comprehensive, the more we should find the system, instead of tending to simplicity, confused and perplexed."
"The different progress of opulence in different ages and nations, has given occasion to two different systems of political economy, with regard to enriching the people. The one may be called the system of commerce, the other that of agriculture. I shall endeavour to explain both as fully and distinctly as I can, and shall begin with the system of commerce. It is the modern system, and is best understood in our own country and in our own times."
"Some writers have exclaimed bitterly against systems of divinity, others have exaggerated the utility of them. Perhaps the truth may be, neither side has taken sufficient pains to understand the other. Theology reduced to a system is nothing more than a regular arrangement of what we hold for religion, and there can be no damage done by such orderly dispositions of truths : on the contrary, much benefit arises to a student of divinity by them, for a system is as advantageous to a minister, as a regular set of books to a merchant."
"By the term architectonic I mean the art of constructing a system. Without systematic unity, our knowledge cannot become science; it will be an aggregate, and not a system. Thus architectonic is the doctrine of the scientific in cognition, and therefore necessarily forms part of our methodology. Reason cannot permit our knowledge to remain in an unconnected and rhapsodistic state, but requires that the sum of our cognitions should constitute a system. It is thus alone that they can advance the ends of reason. By a system I mean the unity of various cognitions under one idea. This idea is the conception--given by reason--of the form of a whole, in so far as the conception determines a priori not only the limits of its content, but the place which each of its parts is to occupy. The scientific idea contains, therefore, the end and the form of the whole which is in accordance with that end. The unity of the end, to which all the parts of the system relate, and through which all have a relation to each other, communicates unity to the whole system, so that the absence of any part can be immediately detected from our knowledge of the rest; and it determines a priori the limits of the system, thus excluding all contingent or arbitrary additions. The whole is thus an organism (articulatio), and not an aggregate (coacervatio); it may grow from within (per intussusceptionem), but it cannot increase by external additions (per appositionem). It is, thus, like an animal body, the growth of which does not add any limb, but, without changing their proportions, makes each in its sphere stronger and more active. We require, for the execution of the idea of a system, a schema, that is, a content and an arrangement of parts determined a priori by the principle which the aim of the system prescribes."
