Doxastic Logic of Demonstratives; Indexical and Reflexive Pronouns in Ascriptions of Propositional Attitudes
Abstract
In this article I will develop the first steps of a wholly general theory of how indexical and reflexive pronouns function in propositional attitude ascriptions. This will involve a theory of ascriptions of de se beliefs and de se utterances, which can probably be also generalized so as to apply to ascriptions of other attitudes. It will also involve a theory about the ascriptions of beliefs or other attitudes a person has at a time about what happens then (attitudes de praesente, as they are sometimes called) and the beliefs of a person concerning the one whom he is addressing (which I might call beliefs de recipiente) etc.. The most distinctive aspect of the theory will be that I will argue that many phenomena associated with such ascriptions that are nowadays most often viewed as pragmatic are semantic. I will use a system of symbolic logic to formalize such ascriptions. I will start from David Kaplan’s Logic of Demonstratives and generalize it into a logic I call Doxastic Logic of Demonstratives, DLD. Crucial to the semantics of the logic will be an exact definition of the adjustments of a character from one context to another
