They are truly incredible, beautiful human beings, who believe in a positive vision of what humans are capable of; that we can rise above superstition and the insanity of uncritical thought. IIRC, Penn once said that a long time ago, they would perform seances, while fully informing the audiences that nothing they're doing is supernatural and there's no actual spirits being summoned; just that they're using the same techniques that con-men mediums use. No matter what they prefaced their performances with, or assured after the performance, many members of the audience didn't believe that these weren't supernatural events, and would believe that they actually communicated with spirits. For that reason, Penn said, they stopped doing them permanently.
