Single Idea 15174

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

Full Idea

For a term to be rigid, it is said there must be real transworld identity prior to our use of the rigid term, ..but this may only be because we have conventional principles for individuating across worlds. 'Let's call him Fred' - perhaps explicitly rigid.

Gist of Idea

A thing doesn't need transworld identity prior to rigid reference - that could be a convention of the reference

Source

Alan Sidelle (Necessity, Essence and Individuation [1989], Ch.3)

Book Ref

A Reaction

This seems right. An example might be a comic book character, who retains a perfect identity in all the comics, with no scars, weight change, or ageing.
