Grice on inflexible tying ('rigid designation')

On p. 143 of "Vacuous Names", Grice gets as close as he wants to Kripke's notion of rigid designation:

"Remarks of the form 'Bill is such-and-such' will

be inflexibly tied, as regards truth-value, not

to possible remarks of the form

'Jones' butler is such-and-such,' but to

possible remarks of the form, 'The person

whom X MEANT when he said 'Let us call Jones' butler 'Bill''

is such-and-such."
