Single Idea 15183
[filed under theme 10. Modality / E. Possible worlds / 3. Transworld Objects / b. Rigid designation
]
Full Idea
'Dthat' is Kaplan's indexical operator; it operates on a given singular term, φ, and makes it into a rigid designator of whatever φ designates in the original context.

A Reaction
I like this idea a lot, because it strikes me that referring to something rigidly is a clear step beyond referring to it in actuality. I refer to 'whoever turns up each week', but that is hardly rigid. The germ of 2-D semantics is here.
