You might say it’s possible that Tom Selleck could have played Indiana Jones. But what does that actually mean? Can you prove that this statement is true or false in the some way? In today’s episode we look at how truth functional statements can be evaluated in the context of more than just our world. We look at the role of Possible Worlds and Modal Logic through the work of Saul Kripke, Ruth Barcan Marcus and David Lewis with a little help from the creative vision of Steven Spielberg and George Lucas. How do we describe the world where the role of Indiana Jones, not might have been, but actually was played by the actor Tom Selleck? And how do we tell the difference between a possible world and the alternate reality of the Multiverse? We also discuss some listener mail about our use of the term ‘Handsome’ and we get a unique first look at Chad’s personal definition of the three types of luck.    Music and Sound Effects Attribution: Gun noise http://soundbible.com/2091-MP5-SMG-9mm.html Whip Crack http://soundbible.com/1375-Whip-Crack.html Music: https://www.facebook.com/musicbyscottbuckley
