Abstract: In this talk, I鈥檒l reflect on the role of worlds鈥攂oth possible worlds and impossible worlds鈥攂oth in the聽semantics of various kinds of languages and logics, and in broader issues in metaphysics. I will argue that, given very modest assumptions concerning the role of worlds in semantics, that any defender of possible worlds in such a role should be聽equally comfortable with impossible worlds.

However, this argument for impossible worlds does聽not transfer straightforwardly to聽logically impossible worlds. So, in the second part of the talk I will consider what we might say, for (or against) properly logically impossible worlds.
