Impossible Worlds

What’s the difference between the merely surprising, the highly improbable, and the truly impossible?

Philosophers often speculate about possible worlds: ways that things could be. Some of them also believe in impossible worlds: ways that things couldn't be. Are impossible worlds places where strange things happen, or descriptions, or abstract objects, or something else entirely? How can you describe an impossibility without contradicting yourself? Could we imagine worlds where even the laws of logic are different? Josh and Ray imagine the unimaginable with Koji Tanaka from the Australian National University, author of "Logically Impossible Worlds." Sunday, December 17 at 11 am.
