Title : Counterfactual attitudes and multi-centered worlds
Author(s) : Dilip Ninan
Abstract :
Counterfactual attitudes like imagining, dreaming, and wishing create a problem for the standard formal semantic theory of de re attitude ascriptions. I show how the problem can be avoided if we represent an agent’s attitudinal possibilities using multi-centered worlds, possible worlds with multiple distinguished individuals, each of which represents an individual with whom the agent is acquainted. I then present a compositional semantics for de re ascriptions according to which singular terms are assignment-sensitive expressions and attitude verbs are assignment shifters.
