Based on the NPR series of the same name, features eighty Americans—from the famous to the unknown—completing the thought that the book's title begins. Each piece compels readers to rethink not only how they have arrived at their own personal beliefs but also the extent to which they share them with others. Featuring many renowned contributors—including Isabel Allende, Colin Powell, Gloria Steinem, William F. Buckley Jr., Penn Jillette, Bill Gates, and John Updike—the collection also contains essays by a Brooklyn lawyer; a part-time hospital clerk in Rehoboth, Massachusetts; a woman who sells yellow pages advertising in Fort Worth, Texas; and a man who serves on Rhode Island's parole board. The result is a stirring and provocative trip inside the minds and hearts of a diverse group of people whose beliefs—and the incredibly varied ways in which they choose to express them—reveal the American spirit at its best.
