| Rigidity, philosophy: Rigidity is an expression for the property of names to stand for the same object in all possible worlds, as opposed to descriptions that are not rigid and can change their reference. E.g. it is pointless to ask whether Napoleon might have been someone else but Napoleon in a possible world, but it is not meaningless to say that there is a possible world in which Napoleon is not the winner of Austerlitz. See also descriptions, names, possible worlds, range, necessity, possibility, reference, semantics of possible worlds, intensions, propositions._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Hartry Field on Rigidity - Dictionary of Arguments
II 54 Name/non-rigid/FieldVs: assume, names would be considered as non-rigid. Then: to believe that Russell was bald, you have to believe a sentence that contains an identifier of Russell "F" and "G" stands for baldness; a sentence of the form ("G (ixFx)". N.B.: why should we introduce possible worlds and propositions together with them? - Assuming propositions and explaining them with worlds and then wanting to distinguish between propositions, then one has to accept names and expressions such as "temperature" as non-rigid. >Names, >Descriptions, >Possible worlds, >Identification, >Cross world identity._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
