Abstract

Frege's puzzle for demonstratives is accounting for the cognitive significance of identity statements containing demonstratives, such as "That [demonstration-1] is identical to that [demonstration-2]". Since the demonstrative 'that' makes the same semantic contribution (has the same 'character') on both occurrences, the difference must be due to the cognitive significance or 'senses' of the associated demonstrations. But what is the sense of a demonstration? Kaplan's suggested solutions in terms of gestures and appearances are not compatible with his general theory, and do not work - a different solution must be found.
