"Reflections on Doubt with Edin Čekić" is a philosophical dialogue on the nature, types, functions, pros and cons of doubt, with emphasis on its role in scientific development. Edin is an Earth Science teacher in Brooklyn, NY and a former philosophy student of mine (Rick Repetti). This discussion was inspired by an informal debate on the utility of doubt on Twitter between myself and a number of Twitter followers of Objectivist philosopher and actor, Mark Pellegrino (who played Lucifer on Supernatural, Jacob on Lost, and number of other prominent roles in various film media).
