ABSTRACT
None of this is to block a Fregean from motivating his position by simply pointing to ‘Hesperus is Hesperus’ and ‘Hesperus is Phosphorus’, thumping the table, and saying: ‘These sentences just obviously differ in meaning – and something’s wrongwith any theory which says that they don’t!’ Personally, I think that this table-thumping argument has more than a little plausibility. But making an intuitive claim about a single pair of sentence tokens (or even several pairs of sentence tokens) is a far cry from presenting a general puzzle aboutmeaningwhich we can then ask whether various approaches to semantics solve.
