Philosophers have been using “philosophical zombies” (hypothetical creatures that behave like humans but aren’t sentient) in thought experiments for many years. Now Stranger Genius Award–winning playwright Paul Mullin is using them in a new play about consciousness, an alcoholic professor, a depressed ex-cop, a rash of beheadings in Seattle, a corporation called “Omnisoft,” and your death. (Yes, yours.) This is a staged reading, not a full production, but it stars John Q. Smith, Susanna Burney, and other actors who are a pleasure to watch.
