Wiggins: 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 - also rigid designators in contexts with "it is possible that .." are not interchangeable (and probably not even in "necessary...").

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).
