"In a life-long partnership with his wife Jessie, James Grier Miller contributed substantially to the development of and to the integration of disciplines through general systems theory, remaining actively engaged in these areas throughout his working life. From his early work on the human brain in the 1940s, Miller worked for over 60 years within influential circles to foster a wide range of new endeavours. In 1949, as Chair of the Psychology Department at the University of Chicago, he founded the new field of behavioural science, devoted to the theoretical integration of the biological and social sciences, through the establishment of the influential Committee on Behavioral Science. In 1955, he got funding from the State of Michigan to set up the Mental Health Research Institute at the University of Michigan; and in 1967, he became President of the University Louisville where he established a Systems Science Institute. His comprehensive integration of the sciences, in Living Systems (1978), remains core to the study of Living Systems and many other fields of research and practice within the systems community."
"Second order Cybernetics presents a (new) paradigm in which the observer is circularly (and intimately) involved with/connected to the observed. The observer is no longer neutral and detached, and what is considered is not the observed (as in the classical paradigm), but the observing system. The aim of attaining traditional objectivity is either abandoned/passed over, or what objectivity is and how we might obtain (and value) it is reconsidered. In this sense, every observation is autobiographical. ⌠The principle of the Black Box is that, where we observe some change in a behavior, we construct and insert a Black Box allowing us to interpret the change as the result of the operation of an invisible mechanism, held within the Box, on what is now seen as input giving rise to output. The observer/scientist develops a description functioning as a mechanism/explanation (i.e. model) which accounts for the transformations of what are now input into output. The explanation is purely historical and the product of the interaction between the observer and his inventive, fictional insertion, the Black Box. What is vital, for the development of second order Cybernetics, is that the Black Box is essentially and crucially a construct of the observer. When we use this concept, we bring the observer in to the process, rather than denying him. That the Black Box requires the observerâs presence is acknowledged, and is circularly connected in. The observer watches and changes. What the observer learns he learns from interaction with the Black Box (which is his construct). When what is observed is observed by an observer, that observer is responsible for the observation, the sense he makes of it, and the actions he takes based on that sense. Von Foerster gives an Ethical Imperative: âAct always so as to increase the number of choices.â (This is joined by an accompanying Aesthetical Imperative: âIf you desire to see, learn how to act.â The third is that we construct our realities. âDraw a Distinction!â"
"We have our gurus, we admire them â and with good reason. But they become in the end a source of laziness because we just accept them and we know the little we know of them without feeling the need either to pursue their work very thoroughly, or the need to question it."
"Tsai's Multi-kinetics were dynamically integrated multiple constructions, employing thirty-two kinetic units, each of which contains a configuration of multi-colored gyroscopic forms. With these elements he created an active environmental field that could, apparently, be infinitely extended. Each motorized unit was a self-sufficient entity, and when it was combined with other similar units produced a large-scale kinetic work that joined visual intensity with mechanical power. By controlling the time sequence of each unit in skillful compositions, Tsai used engineering principles to achieve aesthetic ends."
"As far as the sensory experience of the spectator goes, the most outstanding American kinetic artist is unquestionably the Chinese-born Wen-Ying Tsai. His pieces, which are perfect on the technological level, serve the primary purpose of giving a complete visual experience to the spectator, whose sound solicitations provoke a choreographic, chromatic and rhythmic response in the âcybernetic sculpturesâ. [...]"
"There can be no doubt that Tsai's phenomena (whether they be works of art in the strict sense, or whether they be fantastic artifices) are extremely important. They show what promises and dangers may be in here in a "play," if it is proposed by a great artist. Because, even if Tsai's phenomena be considered artifices, there can be no doubt that Tsai is a great artist. Not because what he does is pleasant, or because he proposes a play, or because he represents the spirit of our times, but because he reveals to us, through artifice or works of art, the concrete experience of a future full of promise or abysmal danger."
"Another tradition in systems theory, known as system dynamics, originated at Massachusetts Institute of Technology. The founder of this tradition was Jay Forrester, a creative engineer who invented the magnetic core memory for computers and who built the , which is now in the Smithsonian Institution."
"The "second order cyberneticians" claimed that knowledge is a biological phenomenon (Maturana, 1970), that each individual constructs his or her own "reality" (Foerster, 1973) and that knowledge "fits" but does not "match" the world of experience (von Glasersfeld, 1987)."
"Systems science is generally said to have emerged during and after World War II, although there were precursors to the basic ideas. The people who created each school of thought were working largely independently, although many of them knew each other. They came from different disciplines, they were working on different problems, they formulated different variations of the principles of systems and cybernetics, and they often chose to affiliate with different academic societies."
"During the 1950s and 1960s most of the work which was called cybernetics tended to focus on control systems in engineering or on applications of the concept of feedback in fields ranging from mathematics to sociology. At the 1970 meeting of the American Society for Cybernetics in Philadelphia Heinz von Foerster sought to redirect attention to the original interests which had led to the founding of the field of cybernetics. In a paper titled "Cybernetics of Cybernetics" he made a distinction between first order cybernetics, the cybernetics of observed systems, and second order cybernetics, the cybernetics of observing systems."
"A key location for the development of general systems theory was the University of Michiganâs Mental Health Research Institute (MHRI) where General Systems, the yearbook of the (SGSR) was based for many years. A mental health research institute may seem a peculiar place to find systems theory."
"A group that was somewhat connected with general systems theory is usually associated with the term, the systems approach. They were located originally at the University of Pennsylvania. They later went to Case Western Reserve University and then back to the University of Pennsylvania. Their founding philosopher was E. A. Singer, Jr. One of Singer's students was C. West Churchman, and Churchman's first student was Russell Ackoff."
"Another group at MIT and Harvard University developed the notion of âorganizational learning.â Chris Argyris and Donald SchĂśn were the key figures in this group. Argyris was a student of Kurt Lewin, who was a participant in the Macy Foundation meetings that were chaired by Warren McCulloch."
"Cybernetics is the study of systems and processes that interact with themselves and produce themselves from themselves."
"Heinz performs the magic trick of convincing us that the familiar objects of our existence can be seen to be nothing more than tokens for the behaviors of the organism that apparently create stable forms. These stabilities persist, for that organism, as an observing system. This is not to deny an underlying reality that is the source of objects, but rather to emphasize the role of process, and the role of the organism in the production of a living map, a map that is so sensitive that map and territory are conjoined."
"Arnold Tustin (1899â1994) introduced the that bears his name to the control community to relate discrete-time and continuous-time systems."
"Interest in the human-operator problem was stimulated by Prof. Arnold Tustin of the University of Birmingham, England, who suggested the application of the delay-line synthesizer to the study of some tracking records which he had brought with him from England. His experimental setup from which data were obtained consisted of a movable handle unit whose output was integrated once and then made to position a mechanical pointer. A second pointer, located next to the handle-driven pointer, was given an input motion consisting of a number of sinusoidal components of a nature sufficiently involved to prevent anticipation by an operator. The operator, upon noticing an error or difference between the two pointers, was required to move the handle in such a way as to reduce this error to a minimum value..."
"Arnold Tustin is best known for his contributions to control theory and its application to electrical machines. However, his interests were much wider than electrical engineering, for he was a polymath who brought a systems approach to each of the many areas that he investigated. In the modern jargon he thought âoutside the boxâ and in doing so championed the use of control systems theory beyond its traditional limits. His impact was such that, in addition to his engineering contributions, he is well known for his systems treatment of economics and to a lesser extent... biology."
"The writer, who as an engineer has spent most of his life in factories, is inclined to look at the basis for investment from a technological point of view... Consider ⌠the class of industrial investments only... The situation is one of entrepreneurs and boards of directors considering, from time to time, various âpossibilities of investmentâ, such as extra lathes or looms, an extension to a factory, a venture in some completely new product, and so on. It is helpful to think of these âopportunities for investmentâ as existing, in a given situation, in great number and variety, whether they are at that moment under active consideration or not. When any such possibility is considered it is assessed in respect of âexpected profitabilityâ. One may conveniently think of all possibilities of investment as âquantaâ that can be placed in a schedule of small ranges of expected profitability according to these assessments. The placement of a given âopportunity for investmentâ on this schedule has some âmargin of uncertaintyâ (a curious analogy with the case of the quanta of physics)."
"An economic system is not a linear system, and... this fact stands in the way of the determination of the parameters of the system by methods that presume linearity, and... it introduces great difficulties in the extrapolation from past behaviour for purposes of prediction."
"It is possible that the major collaboration between economists and engineers is still to come, in the greater use of physical analogues and computers of the analogue type to avoid the difficulties of calculation. Apart from their major use as possible tools for economic regulation, physical analogues have a subsidiary use, for there are students of economics, as there are many students of engineering, who can better understand the significance of the somewhat formidable mathematics that tends to be used in this field, if they can first acquaint themselves with the types of behaviour in question as exhibited by physical objects that can be seen, felt, handled and experimented with. It may also be suggested that economists may find that what they have to say about economic policy will be very readily assimilated by one group of attentive pupils, namely the scientists, engineers and technicians of industry, if explanatory notions can be drawn from the theory of automatic control, which is now part of a normal engineering education. The aim of this essay has been to give explanations of system behaviour, and some approaches to its analysis, using geometrical construction and physical analogy where possible to clarify the implications of the more usual formal algebraic approach."
"Simulators set up the required system of interdependences, usually between electrical potentials or voltages as variables, by means of valve-amplifiers and electrical networks. Since the voltage across a capacitance is proportional to the integral of a current, that across an inductance to the first derivative of a current, and that across a resistor to the current itself, it is possible to arrange a network of electrical elements, with amplifiers and feeds-back where necessary, so that a given linear differential equation is caused to relate an âoutputâ voltage to an âinputâ voltage. Thus a given linear system of interdependences can be simulated, either directly or in any convenient transformation. If non-linear relationships are required there is no universally applicable simple device, but there do exist a great variety of non-linear elements with non-linear characteristics that are known and to some extent; adjustable. These include non-linear resistors... and the characteristic curves of thermionic valves, of rectifiers and discharge vessels and of magnetic materials. Limits may be set by the use of neon tubes that become conducting when a certain voltage is exceeded, or by relays, and so on"
"The âtheory of control systemsâ in engineering is now a well-developed subject, making use of some remarkably powerful concepts and methods of analysis, especially in relation to problems of stabilization and the prevention of unwanted oscillations."
"The striking parallel between the economic models that are currently under discussion and some engineering systems suggests the hope that in some way the rapid progress in the development of the theory and practice of automatic control in the world of engineering may contribute to the solution of the economic problems."
"The separate excitation of the dynamo corresponds with the independently determined investment in the economic model, and the total excitation with income. Perhaps in this electrical age, the conventional metaphor of âpriming the pumpâ might be dropped in favour of âexciting the dynamoâ."
"Actual economic systems are constantly subjected to change and disturbances, which would result in irregularity."
"Once a full-employment policy has been adopted... the economic âsystemâ just on that account is significantly different. Its equilibrium position has been shifted to a rising curve of trend close to and following the employment ceiling. The conditions of stability about this new level are radically different because the region of operation is now within the less flexible and sharply non-linear range of employment saturation"
"There are certain formal similarities between the problems of devising policies for economic stabilisation and those of designing automatic control systems. Methods have recently been developed by engineers for analysing the dynamic properties of quite complex models... [which] can also be used for the analysis of dynamic process models in economics... Professor Tustinâs book contains material of fundamental importance for all who are engaged in either theoretical or empirical studies of dynamic processes in economics. It throws new light on the possibilities and the difficulties of quantitative research in this field."
"Two kinds of self-controlling machines exist: the regulators whose effect has a fixed value and the Servo-mechanisms whose effect has a value depending on the value of a variable which is the âcontrol.â The idea is simple and reveals itself to be accurate. We have found it confirmed by the technical authority, Prof. Arnold Tustin, of the University of Birmingham, who during the war elaborated a system for the movement of gun turrets and naval guns. According to him, if a machine were entrusted with driving a car, it would be a regulator on a straight road and a servo on a winding one."
"During the early phase of World War II, Britain was challenged to refine the understanding of human control of tanks and aircraft. The first engineering-oriented manual control models were probably those of Prof. Arnold Tustin in the United Kingdom applied to tank-control, followed closely by models by J.P. North of Boulton- Paul Aircraft Co."
"Methods by which engineers stabilise their mechanisms suggest analogous possibilities for stabilising economic systems."
"Feedback: It is the fundamental principle that underlies all self-regulating systems, not only machines but also the processes of life and the tides of human affairs."
"He is transported to that curious world of decibels and negative frequencies where filter experts live."
"Already well known to engineers all over the world as a pioneer in the development of automatic control, it may well turn out that Gordon Brown will make a still deeper mark on the engineering development of this century."
"The topic that I have attempted to explore is the usefulness of these notions of the engineer, about feeds-back, harmonic components and the like, in application to the analogous problems of economic fluctuation and economic regulation."
"Consideration of a further possibility, namely that of constructing physical systems that are analogues of the economic system, and of observing and recording their behaviour."
"When beliefs need some modification, We make it with much trepidation, For our world is then new, And things seem all askew, 'til we're used to the new formulation."
"The analysis of engineering systems and the understanding of economic structure have advanced since then, and the time is now more ripe to bring these topics into a potentially fruitful marriage."
"The nature of the instability of an unregulated free-enterprise system is only now beginning to be clearly understood. Perhaps the degree of understanding already attained ensures that the grosser shortcomings have gone for ever, and to that extent the conflict between Capitalism and Communism is about issues that belong to the past. It may now be too late. The gods must smile to note how different the state of the world might have been if the progress of economic thought of the last twenty years had been advanced by even ten years. The possibility of a stable economic life with full utilization of our resources is still not sufficiently assured, and it is extremely important that it should be so assured, and that the whole world should accept this as a fact. The work that is being done in econometrics is massive, and undaunted by mathematical difficulties, but it appears, at any rate as viewed from outside, to be unclear as to its aim."
"With the death of Lawrence K. Frank on September 23, 1968, one of the founders and major catalysts of the child development movement was lost to the field."
"Frank was one of the two or three men who used foundations the way the Lord meant them to be used."
"We are living the events which for centuries to come will be minutely studied by scholars who will undoubtedly describe these days as probably the most exciting and creative in the history of mankind. But preoccupied with our daily chores, our worries and personal hopes and ambitions, few of us are actually living in the present."
"[I call for] imagination and courage in the endless endeavor to make human life more meaningful and significant, more nearly expressive of the values we cherish... A national policy for the family will earn affirmation and as such should give re-direction to what we are now doing in our social life, and new hope and inspiration to individual men and women and new promise to youth."
"We exist in the geographical environment, moving about in space-time, as we carry on our continual intercourse with nature, through breathing, drinking, eating, absorbing light, heat and other forms of radiant energy, eliminating through breathing, urination and defecation, through the skin and by radiation of heat, as the geographical environment flows in and out of us, as it does in all other organisms."
"A policy is a formulation of long term goals and purposes and of the values and aspirations by which those goals and purposes are not only defined but are to be translated into activities and practices. Thus a policy is an affirmation, perhaps a reaffirmation, of what may be taken for granted or is implied, but what is frequently ignored or neglected or inadequately recognized in plans and programs and customary operations. Sometimes a policy serves to point out where these goals and purposes and these values are being blocked or sacrificed to various short-term ends or convenience."
"When we scrutinize the actual procedures that may be called projective methods we find a wide variety of techniques and material being employed for the same general purpose, to obtain from the subject 'what he cannot or will not say,' frequently because he does not know himself and is not aware what he is revealing about himself through his projections."
"A policy therefor might be likened to strategy, the broad, overall, long term conception which gives direction and purpose to the tactics of immediately daily operations and decisions."
"While he served as a foundation officer, he fostered studies of child growth and development, adolescents, family living, and aging; parent education programs; and nursery schools. He was long active in the field of mental health, stressing what is now called "Primary Prevention, "and emphasizing the importance of mental health programs in schools and colleges."
"The concept of teleological mechanisms, however it be expressed in many terms, may be viewed as an attempt to escape from these older mechanistic formulations that now appear inadequate, and to provide new and more fruitful conceptions and more effective methodologies for studying self-regulating processes, self-orienting systems and organisms, and self-directing personalities. Thus, the terms feedback, servomechanisms, circular systems, and circular processes may be viewed as different but equivalent expressions of much the same basic conception"
"The concepts of purposive behavior and teleology have long been associated with a mysterious, self-perfecting or goal-seeking capacity or final cause, usually of superhuman or super-natural origin. To move forward to the study of events, scientific thinking had to reject these beliefs in purpose and these concepts of teleological operations for a strictly mechanistic and deterministic view of nature. This mechanistic conception became firmly established with the demonstration that the universe was based on the operation of anonymous particles moving at random, in a disorderly fashion, giving rise, by their multiplicity, to order and regularity of a statistical nature, as in classical physics and gas laws. The unchallenged success of these concepts and methods in physics and astronomy, and later in chemistry, gave biology and physiology their major orientation. This approach to problems of organisms was reinforced by the analytical preoccupation of the Western European culture and languages. The basic assumptions of our traditions and the persistent implications of the language we use almost compel us to approach everything we study as composed of separate, discrete parts or factors which we must try to isolate and identify as potential causes. Hence, we derive our preoccupation with the study of the relation of two variables. We are witnessing today a search for new approaches, for new and more comprehensive concepts and for methods capable of dealing with the large wholes of organisms and personalities."
