Barbara Ehrenreich has her critics—I thought her Nickel and Dimed was fairly condescending to working-class people—but even those critics must admit that she’s a gifted essayist and a relentless, curious thinker. Her new book, Living with a Wild God: A Nonbeliever’s Search for the Truth About Everything, is partially a memoir about finding an areligious belief system. But it’s also about our relationship to science, and why we cling, white-knuckled, to things that we consider to be truth. It’s a journey that we are all—atheist, religious, unsure—having together; everyone identifies with this story. (Town Hall, 1119 Eighth Ave,, 7:30 pm, $5)
