This book is dedicated to all those heroes and heroines who have seen and will see life as a daring adventure to be given in the name of service to humanity, to justice and to freedom. We know a few of them, but many others are lost among the nameless crowd. Albert Camus and Martin Luther King Jr are two first class role models who lived out thier passion for justice and freedom. Today, they are among the heroes who are well remembered around the world. The following words seem appropriate to reflect what they stood for: “For all who have sought to make a difference in the lives of men by their service and life, and to lighten the dark places of the earth” (Source: inscription on the wall of the Civil Rights Museum, 16th street, Birmingham, Alabama, USA) (Author unknown).
