| Description | Some authors (e.g. Wisniewski, Fritz) recently proved that there must be possible world propositions that cannot be expressed in language. In this talk, I show particular examples of fine-grained (hyper-)propositions that correspond to some such possible world propositions. They contain notions such as assertion, knowledge, belief, truth, and necessity. The inexpressibility (first noticed by Prior and Tichy on the example of the Liar paradox) thus reveals principal limits on any logical explication of these notions. |
