Theodore Sturgeon quote: “Logic and truth are two very different things, but they often look the same to the mind that’s performing the logic.”

“Insanity is often the logic of an accurate mind overtasked.”

Oliver Wendell Holmes (1809–1894) Poet, essayist, physician

The Autocrat of the Breakfast Table (1858)
Context: Insanity is often the logic of an accurate mind overtasked. Good mental machinery ought to break its own wheels and levers, if anything is thrust among them suddenly which tends to stop them or reverse their motion. A weak mind does not accumulate force enough to hurt itself; stupidity often saves a man from going mad.

“Two people can see the same thing, disagree, and yet both be right. It's not logical; it's psychological.”

“Perhaps the logical conclusion of everyone looking the same is everyone thinking the same.”

“A frequent source of misunderstanding has to do with the interpretation of fuzzy logic. The problem is that the term fuzzy logic has two different meanings. More specifically, in a narrow sense, fuzzy logic, FLn, is a logical system which may be viewed as an extension and generalization of classical multivalued logics. But in a wider sense, fuzzy logic, FLw is almost synonymous with the theory of fuzzy sets.”

Lotfi A. Zadeh (1921–2017) Electrical engineer and computer scientist

In this context, what is important to recognize is that: (a) FLw is much broader than FLn and subsumes FLn as one of its branches; (b) the agenda of FLn 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 FLw

“Since my logic aims to teach and instruct the understanding, not that it may with the slender tendrils of the mind snatch at and lay hold of abstract notions (as the common logic does), but that it may in very truth dissect nature, and discover the virtues and actions of bodies, with their laws as determined in matter; so that this science flows not merely from the nature of the mind, but also from the nature of things.”

“There is no such thing as truth. The only thing that is actually there is your "logically" ascertained premise, which you call "truth."”

“The term fuzzy logic is used in this paper to describe an imprecise logical system, FL, in which the truth-values are fuzzy subsets of the unit interval with linguistic labels such as true, false, not true, very true, quite true, not very true and not very fake, etc…. As a consequence, the truth tables and the rules of inference in fuzzy logic are (i) inexact and (ii) dependent on the meaning associated with the primary truth-value true as well as the modifiers very quite.”

“Logic and ethics are fundamentally the same, they are no more than duty to oneself. They celebrate their union by the highest service of truth.”

Logik und Ethik aber sind im Grunde nur eines und das-selbe.
Pflicht gegen sich selbst. Sie feiern ihre Vereinigung im höchsten Werte der Wahrheit...
