The theme of this 20th edition is “Laughter,” and as usual the organizers have brought together an eclectic assortment of writers, artists, scientists, scholars, and performers to address the topic in dozens of programs running through 11/15, including lectures, readings, discussions, and theatrical and musical presentations. Tickets are available via the festival box office at 312-494-9509 or online at chicagohumanities.org; advance purchase is encouraged, as a $5 per ticket surcharge applies at the door. Many of the high-profile events are now sold out, but here’s a few recommendations for ones that weren’t at press time; for a complete schedule see the festival Web site.
