„In the folklore of systems engineering, there are sayings, “If it isn't testable, it isn't a requirement,” and, “If it is not quantifiable, it is not testable.” I had always tended to subscribe to the particle of wisdom in these sayings. One of the many lessons that I learned from the CATIE experience, however, was that systems engineering had to be able to deal directly and purposively with what are usually considered to be strictly qualitative (unquantifiable) aspect of systems, such as quality of life, for example. The agricultural practices of these small farmers in Central America is such a large part of their lives that to change any part of their agricultural practices might be seen as diminishing their quality of life - even with respect to the color of the beans that the new practices might require. But even if we cannot deal directly with quality of life or user friendliness or enmity/sympathy, we can identify quantifiable figures of merit relating to these qualitative aspects and if we find enough figures of merit and combine them suitably, we might eventually obtain agreement that we have captured the essence of the qualitative aspect, at least as far as this particular set of stakeholders is concerned.“

„In our definition of system we noted that all systems have interrelationships between objects and between their attributes. If every part of the system is so related to every other part that any change in one aspect results in dynamic changes in all other parts of the total system, the system is said to behave as a whole or coherently.“

—  Arthur D. Hall American electrical engineer 1925 - 2006

At the other extreme is a set of parts that are completely unrelated: that is, a change in each part depends only on that part alone. The variation in the set is the physical sum of the variations of the parts. Such behavior is called independent or physical summativity.

„We are not simply in the universe, we are part of it. We are born from it. One might even say we have been empowered by the universe to figure itself out — and we have only just begun.“

Контексте: Yes, the universe had a beginning. Yes, the universe continues to evolve. And yes, every one of our body's atoms is traceable to the big bang and to the thermonuclear furnace within high-mass stars. We are not simply in the universe, we are part of it. We are born from it. One might even say we have been empowered by the universe to figure itself out — and we have only just begun.

„An internal combustion engine is 'clearly' a system; we subscribe to this opinion because we know that the engine was designed precisely to be a system. It is, however, possible to envisage that someone (a Martian perhaps) totally devoid of engineering knowledge might at first regard the engine as a random collection of objects. If this someone is to draw the conclusion that the collection is coherent, forming a system, it will be necessary to begin by inspecting the relationships of the entities comprising the collection to each other. In declaring that a collection ought to be called a system, that is to say, we acknowledge relatedness. But everything is related to everything else. The philosopher Hegel enunciated a proposition called the Axiom of Internal Relations. This states that the relations by which terms are related are an integral part of the terms they relate. So the notion we have of any thing is enriched by the general connotation of the term which names it; and this connotation describes the relationship of the thing to other things… [There are three stages in the recognition of a system]… we acknowledge particular relationships which are obtrusive: this turns a mere collection into something that may be called an assemblage. Secondly, we detect a pattern in the set of relationships concerned: this turns an assemblage into a systematically arranged assemblage. Thirdly, we perceive a purpose served by this arrangement: and there is a system.“

„The merit of Marx is that he suddenly produces a qualitative change in the history of social thought.“

—  Ernesto Che Guevara Argentine Marxist revolutionary 1928 - 1967

Notes on the Cuban Revolution (1960)
Контексте: The merit of Marx is that he suddenly produces a qualitative change in the history of social thought. He interprets history, understands its dynamic, predicts the future, but in addition to predicting it (which would satisfy his scientific obligation), he expresses a revolutionary concept: the world must not only be interpreted, it must be transformed. Man ceases to be the slave and tool of his environment and converts himself into the architect of his own destiny.

„There was a plea from honourable Members relating to the need for formal Gross National Product figures. Such figures are very inexact even in the most sophisticated countries I think they do not have a great deal of meaning, even as a basis of comparison between economies. That other countries make use of them is not, I think, necessarily a good reason to suppose that we need them. But, although I am not entirely clear what practical purpose they would serve in Hong Kong, I am sure they would be of interest. I suspect myself, however, that the need arises in other countries because high taxation and more or less detailed Government intervention in the economy have made it essential to be able to judge (or to hope to be able to judge) the effect of policies, and of changes in policies, on the economy. One of the honourable Members who spoke on this subject, said outright, as a confirmed planner, that he thought that they were desirable for the planning of our future economic policy. But we are in the happy position, happier at least for the Financial Secretary where the leverage exercised by Government on the economy is so small that it is not necessary, nor even of any particular value, to have these figures available for the formulation of policy. We might indeed be right to be apprehensive lest the availability of such figures might lead, by a reversal of cause and effect, to policies designed to have a direct effect on the economy. I would myself deplore this.“

„Ur-Fascism is based upon a selective populism, a qualitative populism, one might say.“

—  Umberto Eco Italian semiotician, essayist, philosopher, literary critic, and novelist 1932 - 2016

Ur-Fascism (1995)
Контексте: Ur-Fascism is based upon a selective populism, a qualitative populism, one might say. In a democracy, the citizens have individual rights, but the citizens in their entirety have a political impact only from a quantitative point of view—one follows the decisions of the majority. For Ur-Fascism, however, individuals as individuals have no rights, and the People is conceived as a quality, a monolithic entity expressing the Common Will. Since no large quantity of human beings can have a common will, the Leader pretends to be their interpreter. Having lost their power of delegation, citizens do not act; they are only called on to play the role of the People. Thus the People is only a theatrical fiction. To have a good instance of qualitative populism we no longer need the Piazza Venezia in Rome or the Nuremberg Stadium. There is in our future a TV or Internet populism, in which the emotional response of a selected group of citizens can be presented and accepted as the Voice of the People.
