P. M. Forni, founder of the Civility Initiative at Johns Hopkins, is America's civility expert. In his first two books, Choosing Civility and The Civility Solution, he taught people the rules of civil behavior and ways of responding to rudeness. Now, in The Thinking Life, he looks at the importance of thinking in our lives: how we do it, why we don't do enough of it, and why we need to do more of it.
