David Wiggins on Necessity - Dictionary of Arguments
II 285 Necessity/QuineVsAristotle/QuineVsEssentialism: the essence not independent of our specification of the objects. >Essentialism, >Essence, >Necessity/Quine. II 292 Wiggins: An Operator "it is necessary that ..." creates opaque contexts: E.g. to be taken for Jekyll is not the same as to be taken for Hyde, although Jekyll = Hyde. >Opacity, >Beliefs, >Speaker intention. Also rigid designators in contexts with "it is possible that .." are not interchangeable (and probably not even in "necessary..."). >Operators, >Rigidity. II 301 Necessary/Wiggins: analog to inner/outer negation: Tradition: to blurr the difference after the first method: E.g. "necessarily Socrates is a human" and "Socrates is necessarily a human". Wiggins pro second method -> Definition satisfaction for sentences with "necessary": Wiggins pro existence as necessary feature -> Existence generalization. II 303 Necessary/de dicto/Wiggins: simply wrong: E.g. necessarily (x)(x = Cicero)> (x is a human). de dicto: is it true? If so, we get the wrong thing: necessarily (Ez)(x)(x = z > (x is a human)._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
