What is Cognitive Science
Thursday, October 27, 2005, 12:00pm - 07:00pm
University of Lisbon
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
"What is Cognitive Science?"
This lunchtime talks series is designed to introduce the University community to issues in Cognitive Science. Cognitive Science is one the the few fields where modern developments in computer science and artificial intelligence promise to shed light on classical problems in psychology and the philosophy of the mind. Ancient questions of how we see the world, understand language, and reason, and questions such as 'how a material system can know about the outside world', are being explored with the powerful new conceptual prosthetics of computer modeling.
