“I have experienced personally over the past few years how a purity of diet and thought are interrelated. And when Americans become truly concerned with the purity of the food that enters their own personal systems, when they learn to eat properly, we can expect to see profound changes effected in the social and political system of this nation. The two systems are inseparable.”

— Dick Gregory

“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.”

C. West Churchman (1913–2004) American philosopher and systems scientist

“[In the year 1957] I have just returned from an exciting meeting of the American Society for Engineering Education where I heard a paper on the new discipline of systems engineering. It is no longer sufficient for engineers merely to design boxes such as computers with the expectation that they would become components of larger, more complex systems. That is wasteful because frequently the box component is a bad fit in the system and has to be redesigned or worse, can lead to system failure. We must learn how to design large-scale, complex systems from the top down so that the specification for each component is derivable from the requirements for the overall system. We must also take a much larger view of systems. We must design the man-machine interfaces and even the system-society interfaces. Systems engineers must be trained for the design of large-scale, complex, man-machine-social systems.”

“The past can be told as it truly is, not was. For recounting the past is a social act of the present done by men of the present and affecting the social system of the present.”

“The systems approach to problems focuses on systems taken as a whole, not on their parts taken separately. Such an approach is concerned with total- system performance even when a change in only one or a few of its parts is contemplated because there are some properties of systems that can only be treated adequately from a holistic point of view. These properties derive from the relationship between parts of systems: how the parts interact and fit together”

“The trouble in school is that you can do so little to help kids because you come up against this dead end of the educational system. I think a comprehensive system is the only answer for these kids, if it is carried through properly. But education reflects the system, rather than changes it. People say it’s an instrument of social change; well, if it is, it’s a bloody slow one. I think education reflects the class system, and the system has to change before education can.”

Barry Hines (1939–2016) British author

Barry Hines 1970 interview

“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.”

“The concept of a system is not a simple or unique one. There are many different kinds of systems, and different systems may be organized and operated in different ways. As individuals we all belong to some social system, we participate in an economic system, we are the product of several educational systems, and we are members of one or more family systems. In a similar fashion, the equipment of which physical systems are made may be members of many other systems, such as electrical, mechanical, sensing, actuating, energy, materials, and/or information systems. One of the challenges to the person who engineers a system is to find the many alternative ways in which the function, the operation, and/or the equipment of concern and interest may be considered, understood, and made to perform most effectively.”
