Sentence examples for designator in from inspiring English sources

However, if one designator in a true identity statement but not the other rigidly designates an entity like H2O diagonally, then the statement is a posteriori, as 'Water = H2O' is.

This would obviously result in taking each rigid designator (in today's terminology) to express an intuition.

It follows that no name of the piece of clay c can be a rigid designator in the standard sense.

Assuming that Kripke's arguments against widescopism are successful, it might appear that any statement S containing a proper name cannot have the same content as a statement S′ that differs from S just in the respect that a proper name in S is replaced by a non-rigid designator in S′.

Intuitively, rigid designation is needed on the part of both designators if there are to be true "theoretical identity statements": statements in which a designator designates by way of expressing explicitly in some manner one of the designatum's theoretically interesting essences.

They need not be rigid designators in models where the possible worlds represent epistemically alternative states.

And again, the rigidity of designators in a true theoretical identity statement is sufficient for the statement's necessity.
