How does a fundamentalist become less conservative? What makes a person intent on marrying choose to remain celibate and enter the priesthood? How can a scientist give up believing in certainty? What makes an organ-playing pastor's wife hit the road with a band and her bass guitar? Every now and then something comes along that challenges our strongly held beliefs: new information, new experiences, or disillusion. Because we've all been there, even when we disagree we respect the beliefs of those who come to their conclusions through careful consideration. And those who have completely reversed their opinions about deeply entrenched ideas are especially compelling. What can we learn from entrepreneurs, pastors, theologians, writers, grief counselors and others about the process of how we form our beliefs? From popular voices such as Leonard Sweet and Frederica Matthews-Green to many new and compelling writers, discover the difference an open mind makes in the lives of those courageous enough to confront their own deeply held beliefs.
