The Eureka Day School in Berkely, California, is a bastion of progressive ideals: representation, acceptance, and social justice. In weekly meetings Eureka Day’s five board members develop and update policy to preserve this culture of inclusivity, reaching decisions only by consensus. But when a mumps outbreak threatens the Eureka community, facts become subjective and every solution divisive, leaving the school’s leadership to confront the central question of our time: How do you build consensus when no one can agree on truth? “Eureka Day is so brilliantly yoked to the current American moment-it’s flighty politics, its deadly folly-that makes you want to jump out of your skin…The plays most astonishingly accurate moment comes when the board convenes a livestream…I’m stilly trying to figure out how hard is appropriate for a critic to laugh at the theatre; this night, I made myself hoars.”-The New Yorker
