Philosophy Lexicon of Arguments

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. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments.
