The 17th annual Chicago Humanities Festival, this year themed “Peace and War,” runs through 11/12, offering dozens of lectures, readings, and discussions by an international coterie of writers, artists, and scholars as well as film screenings (see reviews in Movies) and theatrical and musical performances. And for the first time the festival introduces science-focused “Wonder Cabinet” programs and free “Sidebars at the Center” events. Programs are $5 in advance, $6 (cash only) at the door, unless otherwise noted. (Tickets for sold-out programs often become available due to attrition; arrive at the venue no later than 30 minutes before the program, and available tickets will be sold on a first-come, first-served basis.) Tickets can be ordered by phone at 312-494-9509 or online at chfestival.org. Following is the schedule through 11/9; a complete schedule is available at chicagoreader.com.
