Academics From The United Kingdom

"Long before the human spirit awoke to clear cognizance of the world and itself, it sometimes stirred in its sleep, opened bewildered eyes, and slept again."

"Socrates woke to the ideal of dispassionate intelligence, Jesus to the ideal of passionate yet self-oblivious worship. Socrates urged intellectual integrity, Jesus integrity of will. Each, of course, though starting with a different emphasis, involved the other. Unfortunately both these ideals demanded of the human brain a degree of vitality and coherence of which the nervous system of the First Men was never really capable."

"As the months of agony advanced, there was bred in the warring peoples a genuine and even passionate will for peace and a united world. Out of the conflict of the tribes arose, at least for a while, a spirit loftier than tribalism. But this fervour lacked as yet clear guidance, lacked even the courage of conviction."

"In some minds the defence of the human spirit was sincerely identified with the defence of a particular nation, conceived as the home of all enlightenment."

"The economic life of the human race had for some time been based on coal, but latterly oil had been found a far more convenient source of power; and as the oil store of the planet was much smaller than its coal store, and the expenditure of oil had of course been wholly uncontrolled and wasteful, a shortage was already being felt. Thus the national ownership of the remaining oil fields had become a main factor in politics and a fertile source of wars."

"The Holy Grail of systems engineering, a generic systems methodology has been the subject of the author’s ongoing research for over 20 years."

"The real world is made from open, interacting systems, behaving chaotically."

"System engineering is the art and science of creating effective systems, using whole system, whole life principles."

"The world about us can be looked at in a variety of ways. One way is to see the world as made up from many interacting systems: weather, societal, economic, ecological, floral, faunal, tectonic plate, oceanic, and so on. This is very much a connected view of the world: nothing is isolated and totally independent; everything is part of something bigger, and everything comprises many interacting parts — subsystems."

"A system is an open set of complementary, interacting parts, with properties, capabilities and behaviours of the set emerging both from the parts and from their interactions to synthesize a unified whole."

"In 1930 I came under the spell of a considerably more literate influence, when I discovered W. Olaf Stapledon's just-published Last and First Men in the Minehead Public Library. No book before or since ever had such an impact on my imagination; the Stapledonian vistas of millions and hundreds of millions of years, the rise and fall of civilizations and entire races of men, changed my whole outlook on the universe and has influenced much of my writing ever since."

"The Space Age had to dawn before the world could understand Stapledon's thoughts and look through his eyes."

"His Marxism, which remained his only irrational faith throughout his life, told him that surely the United States could never be a positive influence."

"In a way, Stapledon took SF to its supreme heights, and there are times when I absolutely wish I could kill him because he has made so much SF instantly obsolete. He's unconcerned with, or plain bigoted about, a great deal; but what he does, he does very, very well...Stapledon is the master of supplying his readers with this raw, astronomical feeling."

"Now, I won't pretend that I made up the idea of writing histories of the future. It had been done numerous times, most effectively and startlingly by the British writer Olaf Stapledon, who wrote First and Last Men and The Star Makers."

"Stapledon's visionary account of the end of a universe and the birth of future universes is one of the high points in all human thought."

"There is, I believe, something, which may be named by the misleading and debased word 'religion', and is the most distinctively human or awakened activity of man. But clearly there is something else, which is also called 'religion', and is his greatest folly and shame."

"These three activities, then, intelligence, love and creative action, which are so closely involved in one another, I cannot but feel to be intrinsically good. In their outstanding expressions they are good in an outstanding degree. Together they form the distinctively human kind of behaviour."

"In the Far West, the United States of America openly claimed to be custodians of the whole planet. Universally feared and envied, universally respected for their enterprise, yet for their complacency very widely despised, the Americans were rapidly changing the whole character of man’s existence. By this time every human being throughout the planet made use of American products, and there was no region where American capital did not support local labour. Moreover the American press, gramophone, radio, cinematograph and televisor ceaselessly drenched the planet with American thought. Year by year the aether reverberated with echoes of New York’s pleasures and the religious fervours of the Middle West. What wonder, then, that America, even while she was despised, irresistibly moulded the whole human race. This, perhaps, would not have mattered, had America been able to give of her very rare best. But inevitably only her worst could be propagated. Only the most vulgar traits of that potentially great people could get through into the minds of foreigners by means of these crude instruments. And so, by the floods of poison issuing from this people’s baser members, the whole world, and with it the nobler parts of America herself, were irrevocably corrupted. For the best of America was too weak to withstand the worst. Americans had indeed contributed amply to human thought. They had helped to emancipate philosophy from ancient fetters. They had served science by lavish and rigorous research. In astronomy, favoured by their costly instruments and clear atmosphere, they had done much to reveal the dispositions of the stars and galaxies. In literature, though often they behaved as barbarians, they had also conceived new modes of expression, and moods of thought not easily appreciated in Europe. They had also created a new and brilliant architecture. And their genius for organization worked upon a scale that was scarcely conceivable, let alone practicable, to other peoples. In fact their best minds faced old problems of theory and of valuation with a fresh innocence and courage, so that fogs of superstition were cleared away wherever these choice Americans were present. But these best were after all a minority in a huge wilderness of opinionated self-deceivers, in whom, surprisingly, an outworn religious dogma was championed with the intolerant optimism of youth. For this was essentially a race of bright, but arrested, adolescents. Something lacked which should have enabled them to grow up. One who looks back across the aeons to this remote people can see their fate already woven of their circumstance and their disposition, and can appreciate the grim jest that these, who seemed to themselves gifted to rejuvenate the planet, should have plunged it, inevitably, through spiritual desolation into senility and age-long night."

"Broadly there are two very different spheres of our unconscious nature. The one is primitive and largely sub-human. It consists of all our bodily needs and our so-called instinctive cravings. It is all that we have in common with the beasts together with all that we share with the lowliest of our own human kind. But in addition to this there are seemingly unconscious factors in our nature which, far from being sub--human, constitute the drive of our nature toward experiences and activities of a kind more developed and more lucid than our extant ordinary conscious nature."

"I am not a Marxist, but I have learnt much from Marxists, and I am not anti-Marxist. If I had to choose (which heaven forefend) between Marxism and Christian orthodoxy I think I should have to plump for Marxism, in spite of the fact that Christianity has the core of truth which Marxism lacks. Marxism and Christianity spring from the same emotional experience, but each in its way misinterprets, falsifies. Marxism by simply denying its validity, Christianity by smothering it under doctrines. I should choose Marxism because I believe that it is pointing the way beyond itself to a deeper, more purged sort of spirituality than Christian orthodoxy can ever arouse in our day … Roughly I may put it that Marx, with all his extravagance, made a positive contribution which we must not ignore. A contribution to a revival of the spiritual attitude, I mean. Frankly, I suspect that there was more of the true spirit in Lenin (or even Haldane) than in most bishops and certainly far more in some quite humble and in many ways objectionable Communists."

"I loathe the urchin’s cruelty to the cat, but I will not loathe the urchin. I loathe Hitler’s mass-torturing, but not Hitler; and the money-man’s heartlessness, but not the man. I love the swallow’s flight, and I love the swallow; the urchin’s gleam of tenderness, and the urchin."

"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."

"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."

"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."

"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"

"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 “control.” 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."

"Arnold Tustin (1899–1994) 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..."

"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."

"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."

"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 ‘outside the box’ 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."

"Actual economic systems are constantly subjected to change and disturbances, which would result in irregularity."

"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 ’possibilities of investment’, 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 ’opportunities for investment’ 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 ’expected profitability’. One may conveniently think of all possibilities of investment as ’quanta’ that can be placed in a schedule of small ranges of expected profitability according to these assessments. The placement of a given ’opportunity for investment’ on this schedule has some ’margin of uncertainty’ (a curious analogy with the case of the quanta of physics)."

"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 ‘priming the pump’ might be dropped in favour of ‘exciting the dynamo’."

"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 ’output’ voltage to an ’input’ 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 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."

"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."

"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."

"Once a full-employment policy has been adopted... the economic ’system’ 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"

"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."

"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 ‘theory of control systems’ 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."

"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."

"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 Tustin’s 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."

"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."

"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."

"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."
