"BIll will be seeking a new position" (non-identificatory stroke of the pen)

If, due to 'repeated conversational occurrences' of "Jones' butler" someone suggests, 'Let us call Jones' butler 'Bill'" the following will hold:

"If Jones has no butler, and if in consequence

it is FALSE that Jones' butler will be seeking

a new position, it will be false [a posteriori]

that Bill will be seeking a new position."

(Grice, 143, "Vacuous Names")
