Does all of reality exceed what we believe about it? Even the reality of fun? How about the reality of pain? Eric Linus Kaplan is an author (Does Santa Exist?), a TV writer (Big Bang Theory, Futurama), and an all-around philosophical dude (Buddhist monk, UC Berkeley philosophy doctoral student). Eric joins philosophy professors Richard Brown and Pete Mandik, co-hosts of the SpaceTimeMind podcast, for a discussion of ontology.
