“There are only two means by which men can deal with one another: guns or logic. Force or persuasion. Those who know that they cannot win by means of logic, have always resorted to guns.”

The Scientific Outlook (1931)
1930s
Context: Ordinary language is totally unsuited for expressing what physics really asserts, since the words of everyday life are not sufficiently abstract. Only mathematics and mathematical logic can say as little as the physicist means to say.

Language as Conspiracy, p. 277
Everything Is Under Control (1998)
Context: You need the "is of identity" to describe conspiracy theories. Korzybski would say that proves that illusions, delusions, and "mental" illnesses require the "is" to perpetuate them. (He often said, "Isness is an illness.")
Korzybski also popularized the idea that most sentences, especially the sentences that people quarrel over or even go to war over, do not rank as propositions in the logical sense, but belong to the category that Bertrand Russell called propositional functions. They do not have one meaning, as a proposition in logic should have; they have several meanings, like an algebraic function.

In this context, what is important to recognize is that: (a) FL_w is much broader than FL_n and subsumes FL_n as one of its branches; (b) the agenda of FL_n is very different from the agendas of classical multivalued logics; and (c) at this juncture, the term fuzzy logic is usually used in its wide rather than narrow sense, effectively equating fuzzy logic with FL_w
