“Ethical judgments can be [should be] included in the scope of science”

“If the chance of error alone were the sole basis for evaluating methods of inference, we would never reach a decision, but would merely keep increasing the sample size indefinitely.”

“There would be cases where we would not want to accept an hypothesis even though the evidence gives a high d.c. [degree of confirmation] score, because we are fearful of the consequences of a wrong decision.”

“The complete analysis of the methods of scientific inference shows that the theory of inference in science demands the use of ethical judgments”

“[Scientists whose work has no clear, practical implications would want to make their decisions considering such things as:] the relative worth of (1) more observations, (2) greater scope of his conceptual model, (3) simplicity, (4) precision of language, (5) accuracy of the probability assignment.”

“[C. West Churchman exposed the indifferentist position of some researchers — planners belonging to this school in the following terms:] And if our clients blow up the world, land us in starvation or totalitarianism, that is too bad, but we remained pure in heart to the last, didn't we?”

“Another way of emphasizing this diversity is to argue that if one cannot forecast (predict), one does not have a theory, and that forecasting is the weakest link in the chain of the management sciences at present. Indeed, if one cannot predict one cannot measure, and if one cannot measure, then there is no "theory."”

“This text grew from the lecture material for the "Short Course in Operations Research" which has been offered annually (since 1952) by Case Institute of Technology.”

“No science has ever been born on a specific day. Each science emerges out of a convergence of an increased interest in some class of problems and the development of scientific methods, techniques, and tools which are adequate to solve these problems. Operations Research (O.R.) is no exception. Its roots are as old as science and the management function. It's name dates back only to 1940.”

“O.R.'s initial development began in the United Kingdom during World War II and was quickly taken up in the United States. This start took place in a military context. After the war O.R. moved into business, industry and civil government. This movement was slower in the United States than in the United Kingdom but in 1951 industrial O.R. took hold in this country and has since developed very rapidly.”

“An objective of O.R. as it emerged from this evolution of industrial organization, is to provide managers of the organizations with a scientific basis for solving problems involving the interaction of the components of the organization in the best interest of the organization as a whole. A decision which is best for the organization as a whole is called optimum decision.”

“The comprehensiveness of OR’s aim is an example of a ‘systems’ approach, since ‘system’ implies an interconnected complex of functionally related components.”

“This text is oriented toward human organizations since this has been the emphasis in the practice of O.R. in business and industry.”

“The concern of OR with finding an optimum decision, policy, or design is one of its essential characteristics. It does not seek merely to define a better solution to a problem than the one in use; it seeks the best solution... [It] can be characterized as the application of scientific methods, techniques, and tools to problems involving the operations of systems so as to provide those in control of the operations with optimum solutions to the problems.”

“Analysis of the mathematical form and underlying principles of games was made by von Neumann " as early as 1928. In this early work von Neumann was not so much interested in executive-type problems as he was in the logical foundations of quantum mechanics. It was not until 1944, when von Neumann and Morgenstern published their now well known Theory of Games and Economic Behavior, that the mathematical treatment of games "took fire."”

“We have overwhelming evidence that available information plus analysis does not lead to knowledge. The management science team can properly analyse a situation and present recommendations to the manager, but no change occurs. The situation is so familiar to those of us who try to practice management science that I hardly need to describe the cases.”

“How can we design improvement in large systems without understanding the whole system, and if the answer is that we cannot, how is it possible to understand the whole system?”

“Operations research '(OR) is the securing of improvement in social systems by means of scientific method”

“The systems approach goes on to discovering that every world-view is terribly restricted.”

“To know that we are measuring real change we need to have a strong theoretical base.”

“A system may actually exist as a natural aggregation of component parts found in Nature, or it may be a man-contrived aggregation – a way of looking at a problem which results from a deliberate decision to assume that a set of elements are related and constitute such a thing called ‘a system.”

“[Wicked problems are] social problems which are ill formulated, where the information is confusing, where there are many clients and decision-makers with conflicting values, and where the ramifications in the whole system are thoroughly confusing.”

“Deception, in turn , suggests morality: the morality of deceiving people into thinking something is so when it is not.[...] The moral principle is this: whoever attempts to tame a part of a wicked problem, but not the whole, is morally wrong.”

“What seems to emerge is not a moral reprimand of the management scientist, but rather a moral problem of the profession, a wicked moral problem.”

“Lindblom (1959) and Churchman (1967) make it clear that the assumption of synoptic or complete rationality in planning systems is not only inadequate in a methodological sense, but illegitimate in an ethical or professional sense.”

“When one is considering systems it's always wise to raise questions about the most obvious and simple assumptions.”

“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.”

“The problem of systems improvement is the problem of the 'ethics of the whole system'.”

“The idea of a ‘system approach’ is both quite popular and quite unpopular. It’s popular because it sounds good to say that the whole system is being considered, but it’s quite unpopular because it sounds either like a lot of nonsense or else downright dangerous – so much evil can be created under the guise of serving the whole.”

“We are always obliged to think about the larger system. If we fail to do this, then our thinking becomes fallacious.”

“The ultimate meaning of the systems approach, therefore, lies in the creation of a theory of deception and in a fuller understanding of the ways in which the human being can be deceived about his world and in an interaction between these different viewpoints.”

“The scientist has to have a way of thinking about the environment of a system that is richer and more subtle than a mere looking at for boundaries. He does this by noting that, when we say that something lies ‘outside’ the system, we mean that system can do relatively little about its characteristics or its behavior. Environment, in effect, makes up the things and people that are ‘fixed’ or ‘given’, from the system’s point of view.”

“The management of a system has to deal with the generation of the plans for the system, i.e., consideration of all of the things we have discussed, the overall goals, the environment, the utilization of resources and the components. The management sets the component goals, allocates the resources, and controls the system performance.”

“For the scientist a model is also a way in which the human though processes can be amplified. This method often takes the form of models that can be programmed into computers. At no point, however, the scientist intend to loose control of the situation because off the computer does some of his thinking for him. The scientist controls the basic assumptions and the computer only derives some of the more complicated implications.”

“In general, we can say that the larger the system becomes, the more the parts interact, the more difficult it is to understand environmental constraints, the more obscure becomes the problem of what resources should be made available, and deepest of all, the more difficult becomes the problem of the legitimate values of the system.”

“The ultimate meaning of the systems approach . . . lies in the creation of a theory of deception and in a fuller understanding of the ways in which the human being can be deceived about (her) his world, and in the interaction between these different viewpoints.”

“However a systems problem is solved—by a planner, scientist, politician, antiplanner, or whomever—the solution is wrong, even dangerously wrong. There is bound to be deception in any approach to the system.”

“It's not as though we can expect that next year or a decade from now someone will find the correct systems approach and all deception will disappear. This, in my opinion, is not in the nature of systems. What is in the nature of systems is a continuing perception and deception, a continuing re-viewing of the world, of the whole system, and of its components. The essence of the systems approach, therefore, is confusion as well as enlightenment. The two are inseparable aspects of human living.”

“A systems approach begins when first you see the world through the eyes of another.”

“There are no experts in the systems approach”

“The systems approach is not a bad idea”

“Knowledge can be considered as a collection of information, or as an activity, or as a potential. If we think of it as a collection of information, then the analogy of a computer's memory is helpful, for we can say that knowledge about something is like the storage of meaningful and true strings of symbols in a computer.”

“To conceive of knowledge as a collection of information seems to rob the concept of all of its life. Knowledge resides in the user and not in the collection. It is how the user reacts to a collection of information that matters.”

“Knowledge is a potential for a certain type of action, by which we mean that the action would occur if certain tests were run. For example, a library plus its user has knowledge if a certain type of response will be evoked under a given set of stipulations.”

“Design, properly viewed, is an enormous liberation of the intellectual spirit, for it challenges this spirit to an unbounded speculation about possibilities.”

“The religious Weltanschauung, … describes a certain kind of relationship – such as love, adoration and obedience – between men and other men, or between men and some superior being. or between men and "Nature".”

“Inquiry is the creation of knowledge or understanding; it is the reaching out of a human being beyond himself to a perception of what he may be or could be, or what the world could be or ought to be.”

“We must face the reality that the enemies offer: what's really happening in the human world is politics, or morality, or religion, or aesthetics. This confrontation with reality is totally different from the rational approach, because the reality of the enemies cannot be conceptualized, approximated, or measured.”

“Finally we should note the basic assumption of the classical laboratory-namely, that nature is neither capricious nor secretive. If nature were capricious, she would tell one observer one thing and another observer a quite different thing... Also nature is not secretive, in the sense that she will not forever hide certain aspects of her being...”

“For the goal planner, reality stops at the boundaries of the problem. For the objective- planner, it stops at the boundaries set by feasibility and to some extent by responsibility. For the ideal-planner, there are no "real" boundaries.”

“Enemies are hostile, out to stop you, to eliminate you and your ideas; they are also to be loved, even as yourself.”

“Suppose we consider, not the rationality of holism, but its spirituality. Holism traditionally says that a collection of beings may have a collective property that cannot be inferred from the properties of its members.”

“I am often inclined to put the implementation questions first, ie, "Can anything be changed?" Should the implementation question not accompany the whole process from its very beginning to its very end?”

“If the story of my early years with Russ sound like they were years of battle, then the sound is correct.”

“Everybody's daily life consists of problems arising from what you decided yesterday. Managers understand that. Mathematicians want to solve a theorem, publish the results and walk away clean. Managers never walk away clean. The real world is a very dirty place.Clarity is supposed to be the objective of science. I disagree. I think the objective of science is confusion, because confusions carries you into problems.”

“I was an Editor-in-Chief of Philosophy of Science during its early years. Now, over a half century later, I have to admit that I was not very clear what the journal was about, except that it tried to reflect on the meaning of science and its relation to other human activities. At this time I am even less sure of its purposes.”

“It would be a good thing, if the systems planner's germination was moral outrage and not just a mild felt need. In other words, I do not think we should view the major problems of the world today with calm objectivity. We shouldn't first ask ourselves for a precise and operational definition of malnutrition. We should begin with 'kids are starving in great numbers, damn it all!”
