D’Army Bailey has embraced many roles in public life. He’s been an activist, a politician, and a distinguished jurist, serving on the Circuit Court bench in Memphis since 1990. He was instrumental in the founding of the National Civil Rights Museum, and he’s also done a few turns as an actor, appearing in films like How Stella Got Her Groove Back and The People v. Larry Flynt. No doubt he has many stories to tell, but in The Education of a Black Radical: A Southern Civil Rights Activist’s Journey 1959-1964, he confines his memoir to one narrow segment of history: his college years, when he evolved from a very bright, conventional young man to a civil-rights firebrand who was expelled from his all-black school for leading student protests.

David Dark—a schoolteacher, scholar and evangelical gadfly—urges his readers to question everything, including the whole of orthodox religion and even their belief in God. Consequently, although his new book was clearly conceived with a Christian audience in mind, Dark’s thoughtful iconoclasm invites anyone to, as he puts it, “submit everything we’re up to, at work and at play, to the discipline of sacred questioning.”
