Psychology professor Stephen Hinshaw, author of Another Kind of Madness, a memoir of mental illness in his own family, discusses the books closest to his heart. Some deal directly with mental illness, like Jeanette Walls' The Glass Castle and William Styron's account of his own depression, Darkness Visible. Some deal with wrenching moral dilemmas, like Beloved and Sophie's Choice. And he draws it all together with E. O. Wilson's Consilience, which seeks to unify all knowledge.
