【 摘 要 】

This paper develops a very simple probabilistic dynamic for-malism for a semantics of epistemic modal expressions that is essentially expressivist in nature, with a notion of information states based on prob- ability spaces. It differs from existing approaches to this task (in partic- ular [22] and [12]) in certain features that make it more appropriate for modelling actual conversational behavior, especially as regards ignorance and unawareness. It will be argued that the latter is important for an adequate treatment of the alleged non-monotonicity of conditionals. Di- rections for further research that follow from the approach will be pointed
