In his memoir Foreskin's Lament, author Shalom Auslander writes about his attempt to break free from the strict, socially isolated Orthodox Jewish environment of his childhood.

Auslander is the author of the short-story collection Beware of God. He's contributed to The New Yorker, Esquire and The New York Times Magazine.

He spent a year reading the entire Encyclopaedia Britannica and writing The Know-It-All, an account of what he learned.

Now author A.J. Jacobs has accomplished another annually retentive feat: Living life the way the Good Book says we should.

The Year of Living Biblically: One Man's Humble Quest to Follow the Bible as Literally as Possible chronicles Jacobs' attempts to follow every rule in the Bible — and considers the lessons he learned along the way.

In a new book about the constitutional separation of church and state, Pulitzer Prize-winning historian Garry Wills insists that that separation was meant as "the great protector of religion, not its enemy." That, as Wills tells guest host Dave Davies, hasn't stopped fervent believers from challenging the concept.

Wills, a translator of St. Augustine and author of What Jesus Meant, is an emeritus professor of history at Northwestern University; the new book is titled Head and Heart: American Christianities.
