“A system is said to be coherent if every fact in the system is related every other fact in the system by relations that are not merely conjunctive. A deductive system affords a good example of a coherent system.”

“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 (1925–2006) American electrical engineer

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.

“For a general semanticist, communication is not merely words in proper order properly inflected (as for the grammarian) or assertions in proper relation to each other (as for the logician) or assertions in proper relation to referents (as for the semanticist), but all these together, with the chain of 'fact to nervous system to language to nervous system to action.”

“In calling society an ecological system we are not merely using an analogy; society is an example of the general concept of an "ecosystem" that is, an ecological system of which biological systems--forests, fields, swamps--are other examples.”

“General systems theory (in the narrow sense of the term) is a discipline concerned with the general properties and laws of “systems”. A system is defined as a complex of components in interaction, or by some similar proposition. Systems theory tries to develop those principles that apply to systems in general, irrespective of the nature of the system, of their components, and of the relations or “forces” between them. The system components need not even be material, as, for example, in the system analysis of a commercial enterprise where components such as buildings, machines, personnel, money and “good will” of customers enter.”

“Just suppose for a moment that every fact reported to us by others were viewed in the light of the skeptical system”

Robert Chambers (publisher, born 1802) (1802–1871) Scottish publisher and writer

Source: Testimony: its Posture in the Scientific World (1859), p. 7
Context: Just suppose for a moment that every fact reported to us by others were viewed in the light of the skeptical system, as to the fallaciousness of the senses and the tendency to self-deception. Should we not from that moment be at a stand-still in all the principal movements of our lives?
