[catalogued under 10. Modality / E. Possible worlds / 3. Transworld Objects / b. Rigid designation]

Full Idea

Kripke's doctrine that natural kind words are rigid designators and our doctrine that they are indexical are two ways of making the same point.


'Indexicals' point things out; 'rigid designators' baptise things for all possible worlds

Gist of Idea

Saying that natural kinds are 'rigid designators' is the same as saying they are 'indexical'

A Reaction

I think I prefer Putnam's terminology, because it is more modest in its claims Kripke gets into trouble when a natural kind in some other possible world is only subtly different from the original. How 'rigid'? Putnam sticks to how the word gets started.
