- The purpose of this article is to provide a non-contradictory interpretation of sentences such as “Smith's murderer might not have murdered Smith”.
- An anti-actualist, two-dimensional framework including partial functions provides the basis for my solution. I argue for two claims.
- The modal1 profile of the proposition (truth-condition) expressed by “The F might not have been an F” (wher “F” is an empirical predicate) is complex: at any world where there is a unique F the proposition is true; at any world without a unique F the proposition has no truth-value; hence, at no world is it false. It remains an open semantic and epistemological question which of the first two kinds of world the actual world is.
- The semantic method should be based on explicit intensionalization in lieu of actualism. Actualism accords a privileged role to the actual world. Explicit intensionalization places all possible worlds, including the actual one, on an equal footing. Syntactically, a lambda-bound world variable replaces the (explicit or implicit) actual-world constant or operator, while the other world variable is existentially bound.
