This talk deals with the conditions under which indexical beliefs, especially beliefs expressed by perceptual demonstratives('this'), spatial indexicals ('here'), and temporal indexicals ('today'), can be retained as time goes by. One of the key issues in the area is this.If one holds an indexical belief by asserting or accepting a sentence containing one of these terms on a given occasion, then what sentence orsentences should one assert or accept on a later occasion in order to preserve the original belief. I critically examine David Kaplan's and GarethEvans's views on the issue and propose an account of persistence on which the notion of a memory demonstrative, a demonstrative typically linked to amemory image of a past object (an object which is no longer perceptually available), plays a central role
