"Dan Barker's Mere Morality is a potent riposte to C. S. Lewis' Mere Christianity , a book much beloved by Christian apologists. Barker exposes the myriad of biblical practices that could be deemed immoral today, especially because so much of the Bible was written within a master-slave view of the world. Mere Morality offers a real-world view of morality grounded in behavioral biology, reason, and law." --Hector Avalos, author of Fighting Words: The Origins of Religious Violence.
