|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.

Non-rigidness/Non-rigid/predicate/Stalnaker: non-rigid predicates: correspond to different intrinsic properties in various possible worlds.
Rigidness/Stalnaker: Does it presuppose cross world identity?.
Dthis/Dthat/Kaplan/Rigid-making operator/Stalnaker: (Kaplan 1978): always refers the object back to the actual world. - (make rigid) - The reference is then in each possible world the original from the real world.
E.g. Julius/Zipper/Evans/Stalnaker: can be interpreted in two ways: a) as abbreviation of a complex singular term dthis [the inventor of the zipper], then the inventor of the zipper is part of the meaning. - And it’s a logical truth that he invented it - b) as a definition: that Julius is the name of a person. - Then it would be a semantic one. ((s) not logical connection) between the name and person. - Then the role of the description, the reference would have to be defined. - E.g. someone catches the name: case a) then he does not understand the statement. - Then dthis [the person to whom Stalnaker referred on the occasion]. - Ad b) if the semantic properties of Julius are part of the historical causal chain, the competent speaker needs to know nothing about it._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
